A History of the Eiffel Tower
A History of the Eiffel Tower The Eiffel Tower is the most outwardly acclaimed structure in France, maybe in Europe, and has seen more than 200 million guests. However it wasnââ¬â¢t expected to be lasting and the reality it despite everything stands is down to an eagerness to acknowledge new innovation which was the way the thing came to be worked in any case. Beginnings of the Eiffel Tower In 1889 France held the Universal Exhibition, a festival of present day accomplishment planned to correspond with the primary century of the French Revolution. The French government held an opposition to plan a ââ¬Å"iron towerâ⬠to be raised at the passageway to the display on the Champ-de-Mars, somewhat to make a noteworthy encounter for guests. One hundred and seven plans were submitted, and the victor was one by designer and business visionary Gustav Eiffel, helped by planner Stephen Sauvestre and architects Maurice Koechlin and Emile Nouguier. They won since they were eager to develop and make a genuine explanation of goal for France. The Eiffel Tower Eiffelââ¬â¢s tower was to be not normal for anything yet fabricated: 300 meters tall, around then the most elevated man-made structure on earth, and worked of a latticework of fashioned iron, a material whose huge scope creation is currently equivalent with the modern upset. However, the structure and nature of the material, utilizing metal curves and supports, implied the pinnacle could be light and ââ¬Å"see-throughâ⬠, instead of a strong square, hold still its quality. Its development, which started on January 26th 1887, was quick, moderately modest and accomplished with a little workforce. There were 18,038 pieces and more than 2,000,000 bolts. The Tower depends on four huge columns, which structure a square 125 meters along each side, before ascending and joining into a focal pinnacle. The bending idea of the columns implied the lifts, which were themselves a generally ongoing innovation, must be painstakingly planned. There are seeing stages at a few levels, and individuals can make a trip to the top. Portions of the extraordinary bends are quite stylish. The structure is painted (and re-painted routinely). Restriction and Skepticism The Tower is currently viewed as a verifiable achievement in plan and development, a perfect work of art for its day, the beginning of another transformation in building. At that point, in any case, there was restriction, not least from individuals stunned at the tasteful ramifications of such an enormous structure on the Champ-de-Mars. On February fourteenth 1887, while development was progressing, an announcement of objection was given by ââ¬Å"personalities from the universe of expressions and lettersâ⬠. Others were doubtful that the undertaking would work: this was another methodology, and that consistently brings issues. Eiffel needed to battle his corner yet was fruitful and the pinnacle proceeded. Everything would lay on whether the structure really worked... The Opening of the Eiffel Tower On March 31st, 1889 Eiffel moved to the highest point of the pinnacle and raised a French banner at the top, opening the structure; different notables tailed him up. It remained the most noteworthy structure on the planet until the Chrysler building was done in New York in 1929, is as yet the tallest structure in Paris. The structure and arranging was a triumph, with the pinnacle dazzling. Enduring Impact The Eiffel Tower was initially intended to represent twenty years however has kept going longer than a century, because of Eiffelââ¬â¢s ability to utilize the pinnacle in analyses and developments in remote telecommunication, permitting the mounting of reception apparatuses. In fact, the Tower was at one point due to be torn down however stayed after it started broadcasting signals. In 2005 this custom was proceeded with when Parisââ¬â¢ first computerized TV signals were communicated from the Tower. Be that as it may, since its development the Tower has accomplished an enduring social effect, first as an image of advancement and development, at that point as of Paris and France. Media of assorted types has utilized the Tower. Its practically unfathomable that anybody would attempt to thump down the pinnacle now, as its one of the most renowned structures on the planet and a simple marker for movies and TV to utilize.

Post-wedding update
Post-wedding update So, Im back in the office after this weekends wedding. It was great to catch up with many old friends, and of course to see my old roommate tie the knot. If youre wondering what a random sampling of MIT alums 3-6 years removed from the Institute are doing job-wise, heres who was around at the wedding: software engineer/Kenjitsu instructor/author, Medical Doctor (resident), engineer for Sony Consumer Electronics, medical school student/NIH researcher, DC-area attorney, MIT physics instructor, engineer for Exxon-Mobil, city planner, chemistry PhD student, and, oh yeah, admissions officer. At the reception, I got to sit next to Julian Wheatley, a member of the Foreign Languages Literatures (Chinese) faculty and housemaster of East Campus dormitory. We chatted a bit about my slowly progressing Mandarin studies, and he pointed me to his new OpenCourseWare 21F.101: Chinese I site. The groom requested a Red Sox update during the reception, so I got on my mobile phone and called Nightline, MITs peer-listening hotline, for the score. Nightlines greatest service is in peer counseling on serious issues like stress, depression, sexuality, etc, but to encourage students to get used to talking with them, theyll take any kind of phone call. The nice Nightline staffer reported that it was 4-2 Red Sox in the 5th inning, as I reported over the DJs microphone minutes later. Sadly, the Sox lost 6-5. I did not report that over the microphone. Back in the office, Ive done two information sessions in two days as well as a local college fair last evening. At the college fair, interestingly, the two most common questions I received were about economics and varsity sports at MIT. If those were your questions, you should check out the Economics Deprtment and Athletics Department. And to the person who asked if we have any computer courses: I assure you, we have plenty.

Contextually, psychosexual development is estimate d by individual students to show how human personality developed in various phases over the course of childhood. In this context, psychosexual theory suggests that human nature is mainly established at the age of five years. As a result of this, early experiences influence the behavior of the individual by playing significant roles that contribute to the progression of the person to a completely developed adult. Learning theory This theory in human growth and development is developed to analyze major issues that are not covered in psychoanalytic theory. In this case, it includes the absence of significant empirical pieces of evidence of supporting psychoanalytic claims by developing an approach that scientifically encompasses all the aspects of development (Burns, 2013). As such, this theory thereby focuses on establishing on the issues that show how behavior is learned. Some of the factors considered for the effectiveness of this approach include classical conditioning mechanism, operant conditioning, and social learning theory. In classical conditioning theory, learning is achieved by the use of a systematic mechanism that focuses on creating an

Uncle Toms Cabin Essay - 896 Words
Few books can truly be said to have altered the course of history, and even fewer can be said to have started an entire war. Uncle Toms Cabin, written by Harriet Beecher Stowe, was one such novel.

The importance of its innovation is to upgrade the technology one step ahead. The upgrading of the cell phones plus the computer features and incorporating them all in one device called tablet was a hell of an innovation. The information about the tablet is gathered through the literature reviews of the articles present in the journals. The surveys are read and the secondary data about the Samsung tablet helped us through the research. The public responded unexpectedly in different areas of the world when it was launched. The business professionals did not get along with the size of the galaxy tablet. The youngsters and the frequently travelling people liked it. but still the innovation was not as big as ipod was. It co uldnââ¬â¢t replace the ipod. So the public acceptance for the tablet turned out to be like people were not expecting a thing as minor as the size to be the problem. I learnt that creating something new is a very risky business. People may or may not want to change their ways of seeing technology so when it comes to a technology then it should be friendly enough to meet all the requirements that the previous technology was unable to meet. We were motivated to find a good interest of people for the tablet technology. The type of innovation was a revolutionary innovation just like the computers came around as a breakthrough but the tablet PCs couldnââ¬â¢t reach that level. Introduction Overview: This project entails detailed information about the innovation embedding in the Samsung. Samsung is a South Korean company that started in 1938 as the trade export company of perishable things. But later Samsung started manufacturing the electronic devices. The breakthrough in the innovation interested the government and many investors to put in more efforts in the research and development. This project tracks the overall details on the sources of innovation and its journey through the development of the new product of Samsung named Tablet PC Galaxy tab. This is a new launch is a lot of expectations are there from the customers because it has been installed with the best applications demanded by the customers. Group information: Group members names This project is basically about the topics of ââ¬Å"sources of innovationâ⬠and ââ¬Å"types and patterns of innovationâ⬠in the product Galaxy Tablet of Samsung. We chose these topics because the electronics devices are nowadays the most prevailing and demanded by customers. The increase in the versatile use of technology like mobile phones and laptops is like a necessity to everyone, ranging from student to highly skilled professionals. The innovation in the technology is so interesting that we decided to choose our favorite and also most famous electronics company nowadays.

Industrial / company setting: The project is done through the industrial setting because there are a lot of interesting researches done on the Samsung progress that caught our attention and interest. It is interesting to know how the innovation management became the crucial part for the success of the digital equipment manufactured by Samsung as compared to its competitors. This innovation boost made its way to the global market and South Korea stamped its quality by doing exports to the rest of the world in its leading technology. The reason to choose the industrial setting is that there were a lot of other companies already present in 1969 when Samsung started manufacturing but Samsung competed with all of those companies. No wonder this aggressively competing trend and unique way of improving Its technology was the reason it grabbed a quick place in the world of technology. The progress has been improving ever since and quality is remarkable. Geographical setting: The country chosen is South Korea. The reason to choose South Korea is that USA has already made its name in the field of technology and development but South Korea started its technology improvement in the 1960ââ¬â¢s and soon it was able to compete with the USAââ¬â¢s top most high tech innovation industry. Samsung competed not only in the innovation of its technology but also through its strategies to market its electronic devises and gained success in just a couple of decades. Aims and Objectives: The aims of this project is to learn about the implementation of the theories of the innovation management and apply this knowledge at the new innovation named tablet of Samsung in the real business world. The objectives of this project are: To learn the ways of the development of new technology of tablet in a unique way. To learn about the sources of innovation that triggered the development of tablet. To understand the pattern and types of innovation in Samsung. To learn how the industry accepted and supported the new technology. How Samsung made its way to create its place in the world of technology smart companies The problem: Our motivation to work on this topic is that innovation is a tricky procedure. The public may or may not accept the up coming product. There has to be an extensive research to make the new product a success. What are the concerns of the new product development or innovation for its success? The problem under focus is ââ¬Å"Is innovation of Tablet going to be easily accepted by the public?â⬠Methodology The research methodology for this project involves extensive research and analysis of using qualitative research methods including journal articles, periodicals, newspaper articles, international journal articles, and online publications. Our group efforts have been made to make this project a complete and as transparent as possible to achieve the highest levels of precision and accuracy. The work is done with proper justification of each point described. The secondary data is being reviewed to conduct the research. Literature Review: The literature review has been done through the electronic libraries of LSE and MiddleSex Universities. The secondary data had been the part of the literature resources available on the internet. The review of these articles and journals broadened our knowledge of innovation sources and the patterns and types. The surveys had been done to observe the innovation. Samsung started in 1938. It was not an electronics company in the beginning as mentioned above. In 1969, the revolutionary innovation boosted the company to manufacture the electronic devices. South Korea, started its innovation revolution journey in 1960s when the government invested in science research and development to make South Korea a major innovator of scientific technologies. This was a turning point for Samsung in 1969 when it started manufacturing the electronic devices. These devices are now prevalent all over the world. The digital products of Samsung are worldly recognized and reputed for their quality. The breakthrough triggered in 1980ââ¬â¢s when the private companies invested more in the technology development. The government slowed down its investment but for sure there was a sudden demand of techno-smart machinery. The advancement occurred when during 1990ââ¬â¢s the innovation phase started and the exploring of emerging technologies started. In 1998 the government doubled its investment in the research and development of the technology and the workforce was increased. (Temporal 2006) The constant innovation and competitive experts in technology raised the quality of the products and entered in the digital age with revolutionary change and opportunity. Going to the official webpage of the Samsung its clear how many awards have been won by Samsung electronics. (Samsung 2010) In 1993, the Chairman of Samsung stressed on the increased branding and advertising of the innovative development of the Samsung digital devices. The completely bureaucratic and centralized organization of Samsung has developed in its research and development capabilities to compete with the next century demands. Samsung is famous with its LCD and plasma flat screens. The quality of the vacuum cleaner and the rest of its electronics products is remarkable. This characteristic paved the way of many developing technology organizations to partner with Samsung and help innovating the technology in the new and interesting ways. The mobile phones of Samsung are famous with their sound quality and camera resolution. This is due to the constant and consistent efforts of the research and development department of the Samsung. The awards winnings for its technology is written all over the profile of the Samsung website. All of the technology journals are full of the remarkable intelligence of the engineers of Samsung electronics. The innovation cycle of Samsung continues in the 2000ââ¬â¢s and on 11August 2010, Samsung is going to launch a new breakthrough technology named Samsung Tablet Pc. The model of tablet is Galaxy Tab GT-P1000. The tablet is the excellent innovation that combines the features of a laptop and those of the cell phone. Just like the iphone it has got the operating system and the RAM of as much as 512MB. There is 15GB internal memory and the 32 GB micro SD card. It displays the 16millions color capacity and is 7 inches TFT screen with the resolution of 1024 X 600 pixels. It has the feature of the internet and wireless synchronization. The video call facility that makes one feel like you are talking to a person like if s/he is standing right in front of you. The wonder battery life of 12 hours and the voice quality is sheer. The network coverage is remarkable. It is quite compact weighing only 380gm. There are other applications in the tablet like the alarm clock, messaging service, movi es, weather, news, mobile games and applications. The soft wares like the MS office suite to make it suitable for the professionals use. The office soft wares are making it very demanding for the business class. (Samsung 2010) Sources of Innovation: Samsung has been working with multiple sources of innovation. The first source of innovation is the government interest and investment in the innovation in the technology especially the mobile phones and accessories. The second sources of innovation are the users as they are the key users of the technology. The mobile users are coming up with a new demand everyday. Samsung gets the feedback of its customers and innovates the accessories and embed them in different new mobile phones providing diversified mobile phone set to the demanding users. (Hippel 1988) Another source of innovation in Samsung is through the joint venture with other partnership organizations. The university of Cape town has recently done partnership with Samsung mobiles to innovate the new mobile phones applications. These are in response to the African needs. The UCT Samsung Mobile Innovation Laboratory (SMILe) is the Samsungââ¬â¢s first manufacturing unit in Africa. This lab had been made to operate for three years. The partners in this project are the Information Systems and Computer science departments, also the Cape IT Incubator and Bandwidth Barn. This laboratory is the effort of the UCT professor named Jean Paul Ven Belle who is the head of Information Systems. The GM of Bandwidth Barn is confident that the new prototypes have been developed by the senior students of the Computer Science department under the guidance of the staff. This source of innovation is users plus manufacturers combined effort that will open new ideas to the world.(sinha 2011) One big source of innovation is the competitorââ¬â¢s latest products. The increasing demands of the customers are diversified and combining them all in one set is a difficult task. Vodafone, T-Mobiles, O2, Motorolla are the key competitors that are competing with the mobile phones of Samsung. One big competitor is Nokia. These companies are all struggling to manufacture the newest and updated versions of the previous devices.(Gossling 2011) The research and development department of Samsung has been working hard. The continuous feedback obtained through the online surveys give new ideas. The focus groups always come up with the new demands. All of new ideas are incorporated in the new technology. The source of innovation for the Samsung Tablet PC was the increased rate of the demands for the cell phones that contain the capabilities of the cell phone as well as the computer. The devices that is as small as a mobile phone and as big as to work comfortably like a laptop of small size. The size of the tablet is 7 inches which is appropriate for the frequent use like a computer. It is a mini computer that facilitates with all of the capabilities of the cell phone too. The consumers demand for the i-phones, and i-mates was increasing. The demand for the ipods to listen to music all the time anywhere also increased. This gave Samsung an idea that there should be a device with innovation in design that contains all of these features as one unit. This gave the idea of the tablet PC. The popularity of the tablet was worth watching when the competitors were unable to incorporate the camera and facilitates with the wireless coverage. Patterns of innovation: The patterns and types of the innovation depends upon the electronic devise under more demand. The type of innovation in cell phones is different for different customers likewise the other technology. The pattern of the innovation ranges from the invention of the new technology and its total life cycle and then the marketing strategies to create the product demand in the market. Samsung has increased its demand by opening the sales and design centers in different countries that contribute greatly in the market share. The countries like USA, Germany, Middle East Countries and Brazil have been demanding the high quality products of Samsung.(Hussain 2006) There are multiple patterns of innovation. One of these patterns is Technology Push or science push innovation. The new invention is push to the market with the help of the Research and development, productions and sales departments with little consideration as to if this invention is going to satisfy the consumer needs or not. This is called the science push model or the linear model of innovation. Another pattern of innovation is the market pull or market driven innovation. This is the type of innovation used by Samsung. Market creates the need for a unique feature in the product and then the research and development starts to work on it. Most of the products of Samsung are manufactured after knowing what the customer wants. A pattern often observed now which has been created by the government interest and investment in the technology is the Innovation double helix. This is like the DNA structure but one spiral of the structure shows the science and the engineering of the technolog y skills. The other spiral is the marketing, management and entrepreneurial skills. The joint ventures of the Samsung with other collaborating parties are working on this pattern. This depends on the type of the innovation. The mobile phones joint venture with the UCT is the example of innovation double helix. The industrial partners are also working on the same pattern. Another pattern is the integrative approach to Tech-push and market pull. This is the combination of the market push and market pull patterns. Samsung is working on this technique on the products like the LCD and plasma TV. The radical pattern is the new and different element which changes the whole technology. This is a technology that is working on the robots in Samsung or the highly specialized with custom details devices or machinery. The tablet is the example of radical pattern of innovation. The incremental pattern of innovation is very commonly observed in the mobile phones. This pattern deals with the improv ing versions of the Samsung mobile phones. Just like the memory cards are coming with higher capacity. And the cameras of the mobiles are coming with the better resolution. The revolutionary innovation is the breakthrough introducing a new industry. The evolutionary innovation pattern is like the incremental product or process improvement. All of these patterns of innovation are being used in one way or the other. (huang 2010) The tablet PC, Galaxy Tab GT-P1000 had the innovation pattern of revolutionary innovation with the mix of the radical pattern of innovation. The invention of Tablet was a breakthrough as the design and shape of the touch screen almost as big as a cell phone was a new look. The incorporation of the cell phones features was like the incremental innovation pattern but this hybrid of innovation patterns for sure brought the technology of advance digital age that left a mark in the history of the technological developments. Galaxy tablets are claimed to the thinnest and lightest weight gadgets that are portable and customer friendly. The introduction to the customers was amazing as the response of the people was like booking of millions of tablets the day it was launched. Many people say that the size of the tablet is not palm friendly but still they use it because of its marvelous features. The patterns of innovation of tablet PC are highly thought and well tested during the manufacturin g. Types of innovation: Samsung uses the multiple types of innovation. The type of innovation depends upon the type of product that requires the innovation techniques. The sector creating innovations are the specific kind of innovation e.g. the plasma TV. These TVââ¬â¢s are sector specific like the higher middle class or the elite class will want to purchase the flat screen plasma. The performance extending innovation is used in the mobile phones where the performance of the mobiles is extended with the incremental innovation of the product development. The technological reorganization is also the incremental innovation of the technology. The old cathode ray TVââ¬â¢s are now replaces with the flat screens. But this replacement is not completely done to make the cathode ray tv obsolete. The innovation of the plasma screens was the reorganization of the technology. Branding innovation is done with each version having the different brand name. likewise the mobile sets have different faces thus different model numbers. So the innovation is done with the brand names put ahead. Design innovation is the type where the design of the product is considered while manufacturing. E.g, the vacuum cleaners with the shapes of dogs or a robot is the design innovation. The design of the pre-existing thing is re-modeled and refigured to create the new look for the customers. The process innovation is the technology plus the management type innovation. Basically this revolves around the complete process of innovation, managing innovation, marketing and advertising the technology such that the strategy is formed. This is the way the product is engineered phase by phase. The management and monitoring for success is done throughout the process of product development life cycle. Along with this the strategies to offer the product and creating awareness amongst the customers is concerned this is all done through this type. This is an extensive process. Reformulation is the type of innovation where the t echnology item is recreated altogether. This is the reengineering of the existing product. The service innovation is the total managerial policy. The strategy to target which segment and then how to create the awareness of the need amongst the customers. The packaging innovation is the attractive new package to attract the customers to go for it. For example the new colors of the mobile phones and the versatile laptop flap covers that can be replaced very easily are the examples of the packaging innovation. Great deal of art work and redesigning and beautification of the technology products is involved. This is also an extensive procedure.(huang 2010) Samsung Tablet PC Galaxy tab GT-P1000 is the design innovation type of innovation. The design of the tablet was the breakthrough and unique of its kind. Its extensive product development life cycle managed to create the demand in the market. As it was a market wanted product as the pattern of innovation shows that it was a market pull product, so it was very much manufactured thinking about the needs of the customers. The customers pattern of use of cell phone plus the laptops was greatly researched. The launch of the tablet was very much appreciated by the customers. It was long advertised and marketed for the home customers and the business customers. The use of the tablet is like replace the blackberries. The total procedure of the innovation was made to be such that it is demanded by all types of customers. The ages of the customers and the usability of the devices was greatly researched to innovate the product that meets the demands of the maximum types of customers.(Oââ¬â¢Co nnel 2005) Data and Findings: The innovation is a completely risky process. This may or may not get accepted by the people. In order to make it appropriate for the high levels of sales, it needs to be public/consumers interacted during the developmental process. The tablet market is increasingly exploding. According to an online research and the focus group discussions, 6% of the people want to purchase the tablet in the next six months time period. (Richard 2011) the likelihood of 6% to purchase the netbook, 14% to purchase the smart phone, 14% to purchase the windows based laptops or computers, shows that the tablet is not going to finish these categories. Using these statistics there is still expectation for the selling of 360,000 tablets at the end of the spring in UK. The rumors about the buying of the tablets shows that the apple ipod are not going make much sales next year. These next twelve months are going to change the purchase patterns of the customers. The innovation is highly appreciated and also con sidered as a style. The customer friendly feature of the tablets gave Samsung once again a bloom in the consumer market. There are quite a lot of complaints from the customers showing that the size of the device is not appropriate. The size is not palm friendly and at the same time its very interesting gadget. The popularity of the tablets is seems amongst the frequent travelers. Conclusions: The Samsung tablet Galaxy tab GT-P1000 shows that innovation is helping a great deal in changing the look of the technology. The launch of the tablet pc was a marvelous innovation that was a designed innovation to meet the increasing demands of the customers. The customers responded to Samsung as soon as the Tablet was launched. The popularity was gained all of a sudden but due to the unfriendly size of the gadget, it did not make a big success like the ipod had done. Samsung has its quality and the customers trust that. The new development of the device was greatly accepted by the people who travel very often and commute long distances. It could not grab the market share of the blackberries or other professional devices available in the market offering business applications. The expectations were high of this device. The uniqueness was expected to prevail but couldnââ¬â¢t make it. The companies researching on how to make it customer friendly in terms of its size are working in the right direction. If the size of the tablet is reduced and the features are enhanced it will for sure be a highly demanded product like the laptops and the ipods were. The innovation should be appreciated but it should be worked well with all the risks. The continuous feedback from the customers for their needs is a good idea. So the companies much not invest too much in the products development and ignore the market aspects of the product that suffice. References: Gossling, R.

Relaxing Travel
Introduction Industry attractiveness and profitability depends on many varied factors. Change in the business environment or industry trends necessarily affect a companyââ¬â¢s profitability and consequently the future of the company (Macclintock, 2010, p. 48).Advertising We will write a custom report sample on Relaxing Travel specifically for you for only $16.05 $11/page Learn More This report looks into changes that have been happening in the airline industry and how the same are likely to affect the future of Relaxing Travel or any other travelling agent in Britain. From discussion in this report, on the changes in the travel industry, it will become clear that the travel agency has to work hard and re-invent self or be faced out of the industry. Changes and How they affect the Future Relaxing Travel Agency Relaxing Travel relies on other companies to provide charter flights for its customers. The company leverages on block bookings of hotels and re sorts to make its money. Secondly, the company thrives on charter flight discounts enjoyed. Resulting from economic downturn in the UK, the fortunes in the sector have plummeted as buyers and suppliers seek out new avenues of saving on their meager resources or cost cutting. For instance, rather than customers or travelers using travel agents, they personally book their accommodation via the internet and seek cheaper travel options while personally engaging budget airlines. Although, this has resulted from the economic downturn and need to save on costs, customer turned competitor of sorts is a likely result of this new development (Gitman McDaniel, 2008, p. 111). Through trial and error, as customers seek cheaper options and thus create their own packages, there is every threat that some of them could plunge into the travel agency business having learnt the ropes of finding best packages. Based on Porterââ¬â¢s five forces model of industry attractiveness and profitability, the f act that customerââ¬â¢s can create their own package means the threat of new entrants in the sector is very high. What the agency should brace for, even when the economic prospects or fortunes of Britain are to become brighter, the firm would still have to contend with increase competition posed by new entrants or customers charting their own packages.Advertising Looking for report on aviation? Let's see if we can help you! Get your first paper with 15% OFF Learn More Increasingly, as well, scheduling flights has become a challenge that travel agents have to contend with or handle. This scenario has evolved due to increasing industrial relations related problems in airlines and environmental challenges. Airlines have faced numerous employee related problems. News of British airline customers striking or threatening to strike has been a common feature. Environmental related challenges have also made air travel uncertain in many ways. For instance, the volcanic ash la st illustrated clearly how environmental challenges can impact on and inconvenience travel agents due to airlines not operating. Going into the future, with threats of global warming and climate change being evidenced, the climate is likely to continue affecting heavily the operations of travel agencies. The impact of the environmental challenges does not only remain at the level of affecting airline schedules but also impacts heavily on travelersââ¬â¢ destinations. Reports of tsunamis, cyclones and flooding of ocean beaches are more pronounced in the now (Gautam, 2008, p. 123). This points to the likelihood, that traveling agents would have to make stopgap consideration or put in place more risk management plans. Such like plans would necessarily result into higher operation costs and less profits for travel agents. In the recent past the Euro has not be performing well internationally. This was because of problems or challenges in some European Union member countries (Lannoo, 2 008, p. 22). The economic slump in Greece for instance influenced very negatively on the demand for the Euro. Due to drastic changes in world markets, exchange rates are becoming harder to predict over time. The travel agents like Relaxing Travel depend on currency exchange rates when it comes to setting prices. Fluctuation or lack of predictability in exchange rates means firms cannot have a stable price for long enough. Moreover, the fluctuations pose the risk of profit loss due to exchange rate changes. The fluctuation in prices due to unstable currency exchange rate impacts negatively on the business of travel agents because it is difficult to come up with a satisfactory pricing strategy. Given the entry, barriers are not very many, there are many competitors in the travel agency industry and more are likely to enter. The entry barriers as well as exit barriers in the industry are few making this a very dynamic sector. This is not a good sign going into the future. It means that as people learn more about destinations and mechanisms involved in travelling, competition can only get stiffer and stiffer. Recommendations Based on the impacts the changes are likely to have on the industry, Relaxing Travel or any other travelling agency for that matter will have to ride on economies of scale to make it cheaper thus attracting customers who would otherwise create their own package. This calls for Relaxing Travel seeking ways of expanding its span through either integration or partnership to enjoy economies of scale (Hill Power, 2002, p. 67).Advertising We will write a custom report sample on Relaxing Travel specifically for you for only $16.05 $11/page Learn More This, based on extrapolations of Fredrick Hegarty (2006, p. 14), would give it cost leadership over any other package that competitors can come up with or that can be developed by customers. The second recommendation for Relaxing Travel is in line with fluctuations in curre ncy. Relaxing Travel has to adopt a dynamic value based pricing strategy early enough. Based on value, despite currency fluctuation related changes, customers will remain loyal and will always appreciate the agency for its quality services. Finally, Relaxing Travel has to take into account the fact that it operates in an industry or sector with less entry and exit barriers. Therefore, they should focus more on value addition on their services. Value addition will ensure that their services have added advantage thus hooking customers despite stiff competition and challenges. The value addition should also take into account environmental challenges that people are concerned about. For instance, by engaging in environmental awareness programs, the travel agency will not only attract environment conscious customers but also keep its customers given they will be well versed with environmental risks affecting operations.

My Work Experience as an Assistant Realtor Essays
My Work Experience as an Assistant Realtor Essays My Work Experience as an Assistant Realtor Essay My Work Experience as an Assistant Realtor Essay Name: Course: Lecturer: Date: My Work Experience as an Assistant Realtor After my parents divorced, my mother decided to start a real estate family business. During the summer, she decided to employ me as an assistant realtor. Working as an assistant realtor requires professional experience and a proper way of managing the real estate properties well. However, with my little professional experience, I was able to work hard thus gaining a lot of experience in the process. I realized that being an assistant realtor, one should commit himself or herself because of the extracurricular activities involved. The nature of the work involved marketing properties, updating databases, agency services, raising the value of the real estate investments through handling the logistics of running the properties, ensuring real estate has achieved the intended revenues, ensuring insurance premiums are achieved and payrolls as well as bills were paid on time. Proper real estate management may contribute to higher income and profits. Thus, I worked hard in order to achieve success in the business. In fact, my mother had a significant influence over my work. She encouraged me to work hard and she arranged several training programs for me in order to be acquainted with more skills on how to operate a successful business. In addition, she directed me on the ways of dealing with customers because I discovered that some of the customers were stubborn and it is hard to deal with them if one is not disciplined or does not have patience. In addition, through the training programs that she organized, I developed better communication skills. This contributed to a competitive business because I managed to win many clients as well as created better relationships with the customers. This is because I had been taught that building a good rapport with customers is vital since it is one way of getting more clients leading to a better performance of the bu siness. In addition, my sister and my brother encouraged me because they showed their appreciation towards my work and decided to help me. Whenever I needed help, they were ready to assist me in accomplishing my goals. Together with my family, we were able to reach to the conclusions faster especially when making decisions. I realized that accomplishing tasks alone is not easy because it needs teamwork. Thus, my family helped me especially when I was dealing with paperwork, updating information and in the area of multiple listing systems. I came to know that when working with a team, work is accomplished in time and high quality services are produced. Moreover, teamwork enables one to identify problems and solve them easily within an organization. Being an assistant realtor requires a lot because one may need to make better decisions and this requires solid thinking or being creative. Despite the business challenges, one is required to be creative when formulating or making sound decisions. This is vital because it helps the business to thrive well in the market. One thing that I realized is that valuing customers and putting them in the forefront is essential. In case one may need to achieve a better performance in business, customers should be his or her first priority. This can be achieved through better communication and building better relationships. Every time, I made sure that I had satisfied the needs of the customers because without careful handling of customers, the business would perform poorly and even operate at a loss. Understanding diverse cultures is essential in business. I came to know that culture is fundamental because I was handling customers of different cultural backgrounds. In addition, I realized that when dealing with marketing properties, I needed to understand cultural perspectives of different customers because this was vital for marketing in the business. Despite culture, language is vital because it breaks the language barrier when dealing with various customers. Moreover, while organizing for advertisements, I discovered that understanding culture and language is crucial. Since I knew English, which most of my clients were conversant with too, I was able to interact with customers as well as pass information to customers using advertisements. I used posters, flyers and utilized the Internet sources well in making sure that the customers received the information about the different services we offered. My work was hectic but I learned that hard work pays and in order to fulfill my duties, I had to comply with the relevant legislations required in the United States of Americaââ¬â¢s law such as the local fair housing regulations as well as the Federal Fair Housing Amendment. This is fundamental because my work included renting houses, updating the information about the properties and completing sellerââ¬â¢s net sheets. Nevertheless, I was responsible for routine operations of delivering documents, running errands like taking photos, placing lockboxes as well as cleaning the office. From these multiple jobs, I discovered that being an assistant realtor meant a lot and one needed to devote his or her entire time to the job at hand. I learned that planning is crucial because without proper planning, I could not be able to accomplish my tasks. Nevertheless, I was responsible for updating contract database, files and faxing documents as well as sending them to the parties involved. This was not an easy task but I dedicated myself and worked hard to provide the best services to my clients as well as ensure the business achieved the intended goals. I worked even up to the weekends because being an assistant realtor required one to be available in order to direct the clients or handle emergency cases. Additionally, I attended official meetings, which were carried out every month and I learned a lot from these meetings. I acquired vital knowledge from attending these meetings. This is because we had people with different professional skills who encouraged me to work hard and be creative especially when making decisions. From this work experience, I have obtained exceptional experience; thus, I will be able to tackle or face any type of challenges in any company or business.

Equation for Reaction Between Baking Soda and Vinegar
Equation for Reaction Between Baking Soda and Vinegar The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas, which is used in chemical volcanoes and other projects. Here is a look at the reaction between baking soda and vinegar and the equation for the reaction. How the Reaction Works The reaction between baking soda and vinegar actually occurs in two steps, but the overall process can be summarized by the following word equation: baking soda (sodium bicarbonate) plus vinegar (acetic acid) yields carbon dioxide plus water plus sodium ion plus acetate ion The chemical equation for the overall reaction is: NaHCO3(s) CH3COOH(l) ââ â CO2(g) H2O(l) Na(aq) CH3COO-(aq) with s solid, l liquid, g gas, aq aqueous or in water solution Another common way to write this reaction is: NaHCO3 HC2H3O2 ââ â NaC2H3O2 H2O CO2 The above reaction, while technically correct, does not account for the dissociation of the sodium acetate in water. The chemical reaction actually occurs in two steps. First, there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid: NaHCO3 HC2H3O2 ââ â NaC2H3O2 H2CO3 Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas: H2CO3 ââ â H2O CO2 The carbon dioxide escapes the solution as bubbles. The bubbles are heavier than air, so the carbon dioxide collects at the surface of the container or overflows it. In a baking soda volcano, detergent usually is added to collect the gas and form bubbles that flow somewhat like lava down the side of the volcano. A dilute sodium acetate solution remains after the reaction. If the water is boiled off of this solution, a supersaturated solution of sodium acetate forms. This hot ice will spontaneously crystallize, releasing heat and forming a solid that resembles water ice. The carbon dioxide released by the baking soda and vinegar reaction has other uses besides making a chemical volcano. It can be collected and used as a simple chemical fire extinguisher. Because carbon dioxide is heavier than air, it displaces it. This starves a fire of the oxygen needed for combustion.

Language and Gender Interaction Essay Example | Topics and Well Written Essays - 2750 words
Language and Gender Interaction - Essay Example In fact, Lakoff also goes further to point out that women find themselves in a no win situation; when they use powerless talk they are not taken seriously and when they become assertive they are frowned upon. This paper is a report on a study carried out to verify whether women indeed employ a register of speech different from that of men. The study also sought to find out if the manner of speech depended on the type of audience being addressed. The audience variables included same sex, mixed sex and an audience younger than the speaker (Children). The rationale of this study was to provide facts, if any were found to exist, about the issue of gender determined language. More often than not, allegations that are mostly aimed at trying to put women down in the social hierarchy have been made to the effect that it exists. Such allegations have rarely been supported by factual data. This study therefore aimed to gather factual data that could contribute to shedding light on whether women's manner of speaking is different from that of men. This could shed light and give direction to the debate. The main thrust of gender-based analyses of language has been the norm-and-devia... The masculine manner of speech is therefore the norm while the feminine method is the deviation, Hall, K. and Bucholtz, M., (1995). This forms the basis upon which the linguistic behavior of either gender is judged. Cameron, et al (1988) point out that it can't be a coincidence that men are aggressive and hierarchically organized conversationalists while women ate expected to provide support to conversation. This position seems to point out to an actual existence of differences in manner of and role in speech delivery that is dictated by individual gender. Indeed that existence of this gender schism is a matter widely taken for granted especially when religious scriptures with Judeo-Christian allegations of male supremacy come into play. Hard data to support such conventions is what is direly needed and there is too little of it. For instance, there is little evidence that in mixed gender gatherings women talk more than men. This is an issue that is assumed rather than proven to be true. Linguists Tannen, Deborah (1994) and Holmes, Janet (2006) have investigated conversational styles in business corporations to verify the gender stereotypes. Their study found that gendered speech does not exist along a continuum. Instead, both males and females use masculine and feminine forms of expression at different times in different contexts. One such context variable is the nature of the speech community. A speech community denotes any group of people coming together to discuss any given issue of mutual interest. Such a community can range from pupil s in a classroom to a crowd at an accident scene. As soon as the group is formed, rules of engagement in the conversation emerge. People will therefore talk differently

MOVIE REVIEW Example | Topics and Well Written Essays - 750 words - 1
Movie Review Example Her head is shaved and her bangles broken. She is made to wear a piece of white unstitched fabric like the rest of the widows there. Chuiya gradually adapts to the lifestyle of Ashram and at the same time, she changes its dreary atmosphere with her innocence, energy and playfulness. Her bonding with two other widows, Shakuntala and Kalyani, is remarkable. Kalyani is the only widow who is allowed to keep her hair because she is forced to prostitute by Madhumati, the head of the ashram, to bring in money for the ashram. Chuiyaââ¬â¢s accidental meeting with Narayan, a rich law student and follower of Gandhi gives a new turn to the plot of the movie. Narayan and Kalyani fall in love but their love affair is short-lived. When Madhumati learns about her love affair, she locks her up in the room. Shakuntala is represented as a positive force in this movie. The scene in which she unlocks Kalyani to meet Narayan is symbolic of freedom of the subjugated women in the name of religion. However, Kalyani refuses to meet Narayanââ¬â¢s parents because upon seeing his home, she realizes that his father was one her clients. From this point onwards, the tragedy in the movie deepens because she commits suicide after returning to the ashram and Chuiya is chosen to do her job. In the last scene of the movie, Shakuntala hands her over to Narayan, who is angered and disgusted by his father, is leaving with Gandhi on a train. The ending scene symbolizes hope and freedom at least for Chuiya, who evades her fate as a cursed widow. This film revolves around widows in India that are treated as outcasts by the mainstream Hindu society. Though this film is set in 1938, and a conversation between Shakuntala and a priest in one of the scenes inform the audience about the new law that allows widows to remarry; yet the sub titles at the end of the movie inform the audience that even at the turn of the 21st century, many women continue

The average cost of a wedding in Patna is near about Rs.10lakh to 15 lakh in high class society and Rs.3 to 5 lakh in mediocre families and it has been increasing consistently by 5% each year. It has highest per capita gross domestic product in Bihar, which is better than the most of the metropolitan area in India. In 2009, World Bank ranked Patna as second best city in India to start a business. There many fashion and designer boutique in Patna and all of them are locally owned, single-unit operation. However there is increasing no of players entering in this sector but primary focus of these shops is to provide dresses and accessories for all occasion, no one provide accessories and dresses specially for wedding only. So the market is currently missing a place to find out a good selection of all the items for wedding together at one place. Target market:- We are going to cater the Hindus because they are the majority. The target market is brides, brides mother, grooms mother, bride and grooms sisters, brides friends. Wedding dress and accessories on average comprise about 6.8% of the total wedding expenditure, while attire and accessories for mother sister and friends comprises 7.1% of the total wedding expenditure. So we are also focusing on this 7.1% along with the 6.8%.People have joint families mostly in Bihar and Patna also. So a wedding generally have 2 mothers, 6-10 sisters and friends. Trends in Target market Because of the enhanced livelihood in Patna people dont mind to spend high amount to make the wedding a memorable one, because it is the one time function. People there are now moving toward modernization. They want to have the marriage both in traditional and modern way.

Positioning Strategy Our store will be positioned in customer mind with its name VIVHA UTSAV Wedding Shop. Any who will hear or see this name, ultimately come know that it is a store for wedding shopping. Sales Strategy Our sales strategy is designed in that way that it will lead to close the deal. When a customer will enter in our shop, she will feel that her place in wedding and needs are very important for us. We will make an environment in which shopping for other items will be as significant as the experience of shopping for wedding attire. At Vivha utsav other wedding parties like mother, sister and friends will also gain equal importance and attention as the bride receives. Market Share Initially our market share will be low or modest.But it is expected to grow at a good rate because of our unique niche the Vivha Utsav is targeting SWOT ANALYSIS Strength 1) It is the only store of its own type. While most of the boutiques focus on selling only wedding dresses, we give importance to other items also. 2) We will provide different attendants to bride, mothers, sisters and friends so that they can buy the most appropriate dress and accessories for themselves. 3) Our wide range of clothing style, designer and accessories. Weakness:- 1) We are planning to cater only the market for brides and her female relatives and friends not the groom wear market. so we may not get the attention of some customer because of this reason. 2) Wedding business is a seasonal business. We will have small no of foot falls in the off season Opportunity 1) Increasing trend of buying designer wedding dresses and accessories. 2) At our shop along with bridal dress and accessory focus is on other items also. Our customer will be offered a wide selection of their desired attire, and their needs will be our primary focus. Threats 1) Competitors who already exist in the market may have prices lower than our products. 2) People who already had a wedding in the past may prefer to go to boutique from where they bought in past.

Some sales goals will be set for all the employees and when the employees will achieve those goals they will be rewarded monrtarily .To achieve those goals employees will need to do the following things:- a) Pay attention to the customer: customers need to be acknowledges right from the time they enter in the store because everyone, who will step in our store, will be preparing for the big event. They need to be taken seriously immediately because they will not be in our store for fun or casual purpose. b) Keep customer focused: The process of choosing bridal attire and accessories can be a longer one, because it is a very important purchase and there are so many variables like colors, type, fabric etc. so if the sale representative will navigate the customer efficiently through the process it can lead to the desired outcome. c) We will not only sell goods but will also sell shopping experience. Because wedding purchase especially bridal attires are as very emotionally attached and memorable process for bride, her mother and friends. So the employees should try to satisfy them in all possible manners so that the experience becomes a positive one so that they recommend us to their friends and relative for wedding purchase. Merchandising Management The dresses and other accessories will be sold on made-to order basis. So a sample of each product of each style will be kept in store so that customer can try on. If however a customer is satisfied with the floor design she can purchase that product. We will contact the designer who set minimums that is we require purchasing a certain number of sample products. We will keep track of our entire sales in computers in terms of no of times particular is purchased, which type of product is most demanding etc. If some items are selling poorly, they will be discounted, sold off rack or will be replaced by new items. 5) Financial Plan Requirements We will need Rs.50 lakh to get our business off the ground. We are currently seeking funding from outside investors and business loans. In the starting we will raise Rs.15 lakh in equity capital. We are seeking investors for additional Rs. 25 lakh and Rs 10 lakh in loans. Use of Funds Funds will be used to pay for renovations, construction of fitting rooms, sales counter, painting, carpeting, lighting, and dà ©cor and display fixtures. We will also purchase inventory computers, a cash register and inventory management system. The remaining of the Startup funds will be utilized to cover operating expenses, such as rent, utilities, marketing, costs and wages. Profitloss projection Based on our marketing plans, location, store size and product offerings we expect to collect annual sales of Rs.5040000 in 1st year. Our average cost of goods sold will be 40%, which leaves us with a gross margin of 60%.Our monthly fixed cost is estimated to be Rs 113125, so we will need to generate sales of Rs 4, 20,000 monthly to reach the breakeven point. We will become profitable monthly basis after our first year. Break even analysis Particulars Amount(Rs) Sales 5040000 Variable cost 3252000 Contribution(sales-VC) 1788000 Fixed cost 1357500 Net profit 430500 Profit volume Ratio = (Contribution/sales)*100 = (1788000/5040000)*100= 35% BEP point (Rs) =Fixed cost/PV ratio = 1357500/35%= Rs.3826510 BEP Point (months) =BEP point (Rs)/monthly sales = 3826510/420000= 9.11 So we will take 9 months and 4 day to reach the break even sales Cash Flow Projections We will collect immediate payment from customer because we will not give credit to customer, so our cash flow statement will be substantially similar to our income statement. Our cash flow statement will clearly demonstrate our ability to cover all bills.

A Phytochemical and Pharmacological Review Essay
Sambong (Blumea balsamifera) is a native flowering or weed that is endemic in the Philippines and other tropical countries. It is a popular herb especially for its healing properties including antidiarrhetic, antigastralgic, expectorant, stomachic, and antispasmodic, among others. Aside from these, sambong is also popular for being emmenagogues, or for stimulating menstruation or the blood flow in the pelvic area and uterus. As cure for menstrual cramps, the sambong leaves are boiled to create a sambong tea, which is then consumed by the patient. Aside from easing the painful cramps by facilitating menstruation, sambong also helps in cleaning the kidneys. The plant is actually especially known as a natural cleansing herb. Since the plant is emmenagogues, drinking the sambong tea is not advisable to pregnant women as well as women who wanted to be pregnant. Moreover, drinking sambong should also be regulated because it also has hallucinogenic effects when excessively consumed Blumea b alsamifera (L.) DC. (Asteraceae), also known as sambong, has been used as medicine for thousands of years in Southeast Asia countries, such as China, Malaysia, Thailand, Vietnam, and Philippines. Sambong is the most important member of the genus Blumea and is an indigenous herb oftropical and subtropical Asia, especially in China. This plant grows on forest edges, under forests, riverbeds, valleys and grasses [4,5]. In China, it is generally a common used herb in the areas south of theYangtze River, such as Hainan, Guizhou, Yunnan, and Guangdong provinces and Taiwan [6ââ¬â8].B. balsamifera is commonly called ââ¬Å"Ainaxiangâ⬠and ââ¬Å"Dafengââ¬â¢aiâ⬠in Chinese and used as incensebecause it has a high level of essential oils [9]. It was originally recorded in ââ¬Å"Bei Ji Qian Jin YaoFangâ⬠in 652 by Sun Simiao. The whole plant or its leaves were used as a crude Chinese traditional medicinal material to treat eczema, dermatitis, beriberi, lumbago, menorrhagia, rheumatism, skininjury, and as an insecticide [10]. Bing Pian and Aipian are two important traditional Chinese medicines (TCMs) extracted from plants and have been used as one in prescriptions for centuries in China. Both of them mainly contain borneol and are similar in efficacy [11]. They are synonymous in the Chineseà pharm aceutical industry nowadays. Before 2010, sambong was one of the most important plant sources for Bing Pian, but since 2010, the Pharmacopoeia of the Peopleââ¬â¢s Republic of China records B. balsamifera as the only plant source for Aipian [11], with a consistent efficacy with B.à balsamifera medicinal materials, which could induce resuscitation, clear heat, and relieve pain. Recently, extracts of its leaves have been verified do display various new physiological activities, such as antitumor , antifungal [13,15], radical-scavenging [16], and anti-obesity properties . The main active compound is L-borneol, which was characterized by a high volatility. Besides, essential oils, flavonoids, and terpenoids with several different biological activities were also reported . These studies could explain why this plant has multiple pharmacological effects. In this review, botanical descriptions, herbal authentications, and phytochemical constituents of B. balsamifera are covered. In addition, the previous in vitro and in vivo studies conducted on its biological activities are reviewed, concentrating on antitumor, hepatoprotective, superoxide radical scavenging, antioxidant, antimicrobial, anti-inflammation, antiplasmodial, antityrosinase, platelet aggregation, wound healing, anti-obesity, disease and insect resistant activities as well as enhancing percutaneous pen etration. Sambong is a half woody, strongly aromatic shrub, densely and softly hairy, 1 to 4 meters high. Stems grow up to 2.5 centimeters in diameter. Leaves are simple, alternate, elliptic- to oblong-lanceolate, 7 to 20 centimeters long, toothed at the margins, pointed or blunt at the tip, narrowing to a short petiole which are often auricled or appendaged. Flowering heads are stalked, yellow and numerous, 6 to 7 millimeters long, and borne on branches of a terminal, spreading or pyramidal leafy panicle. Discoid flowers are of two types: peripheral ones tiny, more numerous, with tubular corolla; central flowers few, large with campanulate corolla. Involucral bracts are green, narrow and hairy. Anther cells tailed at base. Fruits are achenes, dry, 1-seeded, 10-ribbed, hairy at top. ââ¬â Considered anthelmintic, antidiarrheal, antigastralgic, antispasmodic, astringent, carminative, emmenagogue, expectorant, stomachic, and vulnerary.Leaves used a flavoring ingredient.

Biological Activities 3.1. Antitumor Activity Hasegawa et al. extracted a dihydroflavonol from B. balsamifera as a result of screening among more than 150 plant materials [12]. The dihydroflavonol components showed the most significant synergism with tumor related apoptosis inducing ligand (TRAIL). It enhanced the level of TRAIL-R2 promoter activity and promoted the expression of surface protein in a p53-independent manner. The ethanol extract of B. balsamifera leaves was tested on male mice to investigate its hepatoxicity. The results exhibited that the hepatic cells, sitplasm, nucleus, and sinusoid of the mice liver were damaged through some changes in the liver color and texture . The methanol extract of B. balsamifera inhibited the growth in rat and showed no cytotoxicity on human hepatocellular carcinoma cells. The methanol extract decreased the expression of cyclin-E and phosphorylation of retinoblastoma (Rb) protein resulting in cell cycle arrest. Likewise, it decreased the level of the proliferation related ligand (APRIL) [60,61]. Moreover, the methanol extract of B. balsamifera was used to determine its cytotoxicity on a panel of human cancer cell lines by MTT assay. There was no regular or acute cytotoxicity on the cells of HepG2, HCT-116, T-47D, NCl-H23 and CCD-18Co [62]. Saewan et al. found six compounds out of nine isolated flavonoids to have cytotoxicity against KB, MCF-7, and NCI-H187 cancer cell lines [14]. These six compounds were evaluated for cytotoxicity against KB,à MCF-7, and NCI-H187 cancer cell lines. Three compounds were active against the KB cells with the IC50 values of 17.09, 47.72, and 17.83 à ¼g/mL, respectively. Another three compounds exhibited a moderate activity against the NCI-H187 cells with the IC50 values of 16.29, 29.97, and 20.59 à ¼g/mL. Luteolin-7-methyl ether showed a strong cytotoxicity against human lung cancer (NCI-H187) cell lines with an IC50 of 1.29 à ¼g/mL and a moderate toxicity against oral cavity cancer (KB) cell lines with an IC50 of 17.83 à ¼g/mL. Li et al. studied the antitumor activity determined by means of 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay [13]. The three endophytic streptomycetes strains of B. balsamifera, including: YIM 56092, YIM 56093, and YIM 56099 exhibited anticancer activity. Yet, different strains displayed different antitumor activities. The YIM 56092 strain displayed a cytotoxic activity on polyketide synthases I (PKS-I) nonribosomal peptide synthetases (NRPS) and P388D1. The YIM 56093 strain displayed a cytotoxic activity on PKS-â⦠¡, NRPS, and P388D1. The YIM 56099 was on the PKS-I, PKS-II, and NRPS. Fuijimoto et al., extracted blumealactone A, B, and C from sambongââ¬â¢s dried leaves and found them could inhibit the growth of Yoshida sarcoma at the concentration of 5ââ¬â10 à ¼g/ml [54]. Lee disclosed a medication combination including sambong (Ainaxiang) and found it could enhance the efficiency of curing hepatoma and pancreatic cancer treatments [63]. Molecules 201 4, 19 9462 3.5. Anti-Microbial and Anti-Inflammation Activity Ongsakul et al. claimed that the crude aqueous and ethanolic extracts of B. balsamifera displayed no significant antibacterial activity against the strains of Staphylococcus aureus and Escherichia coli [73]. However, the stain of B. balsamifera, including YIM 56092 and YIM 56093, displayed a significant activity against S. epidermidis, such that YIM 56099 was active against E. coli. There seems to be no antimicrobial activity against S. aureus, Klebsiella pneumonia, and Candida albicans [13]. Chenisolated twelve new compounds [9], four of which displayed inhibitory activities against LPS-induced NO production in RAW 264.7 with the IC50 values of 40.06, 46.35, 57.80, and 59.44 à ¼g/mL, respectively. Sakee et al. reported the essential oil of B. balsamifera to have a minimum inhibitory concentration (MIC) of 150 à ¼g/mL and 1.2 mg/mL against Bacillus cereus, S. aureus and Candidaà albicans, respectively [74]. Furthermore, the hexane extract inhibited Enterobacter cloacae and S. aureus. These results suggested that the extracts of B. balsamifera possessed an activity against certain kinds of infectious and toxin-producing microorganisms. It could potentially be utilized to prevent and treat microbial diseases. 3.6. Antiplasmodial Activities According to the traditional efficacy of relieving fever, the methanol extract of B. balsamifera from Forest Research Institute Malaysia was investigated for any potential antiplasmodial activity. The extracts of roots and stems exhibited some activity against Plasmodium falciparum D10 strain (sensitive strain) with an IC50 value of (26.25 à ± 2.47) à ¼g/mL and (7.75 à ± 0.35) à ¼g/mL, respectively [75]. 3.8. Platelet Aggregation Activities The concentration of 1.26 à ¼mol/L blumeatin displayed a significant promoting activity on the rat and human platelet aggregation caused by arachidonic acid, 5-hydotypamice, and epinephrine. However, concentrations of 0.315 and 2.52 à ¼mol/L inhibited platelet aggregation. It suggested that the effects of blumeatin on the platelet aggregation were dependent upon the concentration used. The injection of B. balsamifera extracts decreased the blood pressure, expanded the blood vessels, and inhibited the sympathetic nervous system in order to address the high pressure and insomnia. The infusion of the plant also had the function of diuresis [67] Mayana (Coeus blumei Benth.) Coleus leaves are commonly known as ati-ati leaves in Malaysia. Previous study has shown that the Coleus leaves have high antioxidant activity and nutritional value. The present work is to investigate whether antioxidant, minerals and phenolic content can be extracted by boiling the leaves in water. The antioxidant was determined by mixing the extract solution with DPPH (2, 2-Diphenyl-1-Picrylhydrazyl) solution using different ratios. Acid ascorbic acid was used as standard in measurement by Uv-Vis Spectrophotometer. Phenolic content was measured by Uv-Vis Spectrophotometer using Gallic acid as standard. There is about 40.77 wt % of antioxidantà activity, 6.256998 wt% of total phenolic content, and some minerals (magnesium, calcium, iron and zinc) existing in solution after the Coleus blumei leaves were removed. The wt% of the phenolic content is directly proportional to the wt% of antioxidant activity. The mineral concentration, antioxidant activity and phenolic content seemed to be highly correlated. As a conclusion, it is proven that the Coleus blumei leaves have high potential value for the nutritional purpose. 2.1 Definition of Coleus Coleus is a name which derives from an earlier classification under the genus name Coleus, species of which are currently included in either Solenostemon or another genus, Plectranthus. The word Coleus come from the Greek ââ¬Å"koleusââ¬â¢, meaning sheath. It is believed that there are 150 species of Coleus .It is a genus of perennial plants, native to tropical Africa, Asia, Australia, the East Indies, the Malay Archipelago, and the Philippines. Many cultivars of the Southeast Asian species Coleus have been selected for their colorful variegated leaves, usually with sharp contrast between the colors where the leaves are green, pink, yellow, maroon, and red. Typically, in Malaysia this plant known as ati-ati. The plants need a well condition of in moist-drained soil to grow, and typically grow 0.5-1 m tall, though some may grow as tall as 2 meters. They are heat-tolerant, though they do less well in full sun in subtropical areas than in the shade. The leaves of the green type are often eaten raw with bread and butter. The chopped leaves are also used as a substitute for sage (Salvia officinalis Linn.) in stuffing. C. aromaticus is used for seasoning meat dishes and in food products (Uphof, 1959) while a decoction of its leaves is administered in cases of chronic cough and asthma (CSIR, 1992). It is considered to be an antispasmodic, stimulant and stomachic and is used for the treatment of headache, fever, epilepsy and dyspepsia (Khory &Katrak, 1999; Morton, 1992) . 2.2 Antioxidant An antioxidant in food is really important as it can protect human body from free radicals activity. It is also has capable of slowing or preventing the oxidation of other molecules. When electrons are transferred form a substance to an oxidizing agent, it called as oxidation reaction. Free radicals can be produced during the Oxidation reactions, where the startà chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves. As a result, antioxidants are often reducing agents such as thiols or polyphenols. Although oxidation reactions are crucial for life, they can also be damaging; hence, plants and animals maintain complex systems of multiple types of antioxidants, such as glutathione, vitamin C, and vitamin E as well as enzymes such as catalase, superoxide dismutase and various peroxidases. Low levels of antioxidants, or inhibition of the antioxidant enzym es, causes oxidative stress and may damage or kill cells. As oxidative stress might be an important part of many human diseases, the use of antioxidants in pharmacology is intensively studied, particularly as treatments for stroke and neurodegenerative diseases. However, it is unknown whether oxidative stress is the cause or the consequence of disease. Antioxidants are also widely used as ingredients in dietary supplements in the hope of maintaining health and preventing diseases such as cancer and coronary heart disease. Although some studies have suggested antioxidant supplements have health benefits, other large clinical trials did not detect any benefit for the formulations tested, and excess supplementation may be harmful In addition to these uses in medicine, antioxidants have many industrial uses, such as preservatives in food and cosmetics and preventing the degradation of rubber and gasoline. Current research into free radicals has confirmed that foods rich in antioxidants play an essential role in the prevention of cardiovascular diseases and cancers. As far as our literature survey could ascertain, antioxidant activities of this plant have not previously been published. Hence, the previous work investigated the possible antioxidat ive effects of freeze-dried powder obtained from aqueous extract of fresh leaves of C. aromaticus. In this study, they had examined the antioxidant activity of CAE (C.aromaticus hydroalcoholic extract) employing various in vitro assay systems, such as the à ²- carotene-linoleate model system, DPPH (2,2-Diphenyl-1-Picrylhydrazyl)/superoxide/ nitric oxide radical scavenging, reducing power and iron ion chelation, in order to understand the usefulness of this plant as a foodstuff as well as in medicine. 2.2.1 Antioxidant Assay using a à ²-carotene-linoleate Model System On the previous experiment, the antioxidant activity of the extract was measured by the bleaching ofà à ²-carotene. By adding CAE and BHT (Butylated Hydroxytoluene) at various concentrations, it can prevent the bleaching of à ²-carotene to different degrees. à ²-Carotene in this model system undergoes rapid discoloration in the absence of an antioxidant. This is because of the coupled oxidation of à ²-carotene and linoleic acid, which generates free radicals. The linoleic acid free radical, formed upon the abstraction of a hydrogen atom from one of its diallylic methylene groups, which attacks the highly unsaturated à ²-carotene molecules. As a result, à ²-carotene will be oxidized and broken down in part; subsequently, the system looses its chromophore and characteristic orange colour, which can be monitored spectrophotometrically. The presence of different antioxidants can hinder the extent of à ²-carotene bleaching by neutralizing the linoleate free radical and other free radicals formed in the system (Jayaprakasha, Singh, & Sakariah, 2001). It also showed that the CAE was found to hinder the extent of à ²-carotene bleaching by neutralizing the linoleate-free radical and other free radicals formed in the system. In comparison, the CAE showed an appreciable antioxidant activity of 83.0% at 250 à ¼g/ml, while BHT, a synthetic antioxidant had 89.6% antioxidant activity at 100 à ¼g/ml. Table 2.1: Antioxidant activity of aqueous extract of C. aromaticus in à ²-carotenelinoleate System Sample Concentration (à ¼g/ml) Antioxidant activity (%) Aqueous extract 125 53.2 à ± 1.04 250 83.0 à ± 1.33 500 91.3 à ± 1.41 BHT 50 64.2 à ± 1.81 100 89.6 à ± 1.52 200 95.3 à ± 1.33 2.2.2 DPPH Radical-scavenging Activity The CAE showed a concentration-dependent antiradical activity by inhibiting DPPH radical with an EC50 value of 210 à ¼g/ml (Table 2). DPPH is usually used as a substrate to evaluate antioxidative activity of antioxidants (Oyaizu, 1986). The method is based on the reduction of methanolic DPPH solution in the presence of a hydrogen donating antioxidant, due to the formation of the non-radical form DPPH-H by the reaction. The extract was able to reduce the stable radical DPPH to the yellow-coloured diphenylpicrylhydrazine. It hasà been found that cysteine, glutathione, ascorbic acid, tocopherol, polyhydroxy aromatic compounds (e.g., hydroquinone, pyrogallol, gallic acid), and aromatic amines (e.g., p-phenylene diamine, p aminophenol), reduce and decolorise 1,1-diphenyl-2-picrylhydrazyl by their hydrogen donating ability (Blois,à Oregano (Origanum vulgare L.)à oregano (Ãâ¢rÃâ¢gÃËÃâ¢nÃ
) [key], name for several herbs used for flavoring food. A plant of the family Labiatae (mint family),Origanum vulgare, also called Spanish thyme and wild marjoram, is the usual source for the spice sold as oregano in the Mediterranean countries and in the United States. Its flavor is similar to that of marjoram but slightly less sweet. In Spain and Italy many other Origanum species are also grown as oregano. A related herb ( Coleus amboinicius ) of the same family, called suganda in its native Indomalaysia, is known as oregano in the Philippines and Mexico, where it is a popular flavoring. Several other herbs also provide spices called oregano, e.g., species ofLippia and Lantana of the verbena family. In all cases the flavoring is made from the dried herbage. Oregano is classified in the division Magnoliophyta, class Magnoliopsida, order Lamiales, family Labiatae . All rights reserved. genus Origanum is a member of the Lamiaceae family and has a complex taxonomy [1]. O. vulgare plays a primary role among culinary herbs in world trade [2]. It is distributed all over Europe, West and Central Asia up to Taiwan [3]. The use of O. vulgare as medicinal plant is believed to be due to biological properties of p-cymene and carvacrol. Bernà ¡th [4] has noted that there are intras- pecific taxa of oregano having no ââ¬Å"oreganoâ⬠character that is based on the presence of carvacrol. Oregano is the common name for a general aroma and flavour primarily derived from more than 60 plant species used all over the world as a spice [5]. Four main groups of plants com- monly used for culinary purposes can be distinguished, i.e., Greek oregano (Origanum vulgare ssp. hirtum (Link) Ietswaart); Spanish origano (Coridohymus capitatus (L.) [2]; Turkish oregano (Origanum onites L.); and Mexican oregano (Lippia graveolens HBK [6]. Origano is the commercial name of those Origanum species that are rich in the phenolicà monoterpenoids, mainly carvacrol and occasionally thymol [7]. A number of chemically related compounds i.e. p-cymene; à ³-terpinene, carvacrol methyl ethers, thymol methyl ethers, carvacrol acetates and thymol acetates; as well as p-cymenene, p-cy- men-8-ol, p-cymen-7-ol, thymoquinone, and thymohy- droquinone are present in the oil of Origanum vulgare which is extremely rich in essential oils (up to 7%) with carvacrol as a major constituent present in very high quantity (75% ââ¬â 95%), followed by p-cymene (4% ââ¬â 14%) and à ³-terpinene (1% ââ¬â 10%). It seems possible that the uses of the plant in traditional medicine can be attributed to the known biological properties of p-cymene and car- vacrol [8]. Many of the studies confirmed the medicinal effects of oregano for human health. The Origanum spe- cies, which are rich in essential oils, have been used for thousands of years as spices and as local medicines in traditional medicine [9]. About 20 European public in- stitutions hold genetic resources of different species of oregano [10]. Marjoram (Origanum vulgare L.) is one of medicinal aromatic plants found wholesale almost in all areas of Albania, which is a perennial plant usually grows in dry area in smaller groups. Oregano plants are collect- ed from natural habitats and used as raw materials in the pharmaceutical, cosmetic and food industry [11]. But many countries start to cultivate it in different areas. In botanical aspects, the oregano populations differ from one to another, that is they vary depending on the content and composition of essential oils [12]. From the quantity and quality of essential oils the values of this plant were determined [11,12]. The different results showed that the effects of oregano antioxidante are associated with high content of essential oils, thymol and carvacrols, and these are the main ingredients in oregano oil. The con- tents of Thymol and Carvacrol in oregano give it differ- ent properties [13]. According to the studies, carvacrol is a powerful bactericidal agent, and provides protection against mold and other common bacteria. The main ob- jective in our study was to investigate the different re- gions and to find the variation for oil content in oregano plant populations. The research expedition was organized in 2012 in the whole territory of Albania. During this expedition are identified and collected 62 accessions. At each location were taken of the 50 samples which derived a main rep- resentativ sample. From the total samples collected, were selected 16 samples mostly widespread of natural popu- lations ofà origano (Origanum vulgare L. sp. vulgare and sp. hirtum). Those samples you perform analyzes for content of oils and their components. The confirmation of 53 essential oil was made to analyses: à ²-Pinene, p- Cymene, à ³-Terpinene, Linalool, Terpinene-4-ol, Thymol, Carvacrol dhe Caryophyllene oxide. The overground parts of the flowering plants (20 ââ¬â 25 cm from the top) were collected during the summer of 2012. The plant material was air dried, packed in paper bags and kept in a dark and cool place until analysis. Plant identity was verified and voucher specimens were deposited at the Institute of Pharmacognosy, Faculty of Pharmacy, Skopje. 2.2. Essential Oil Isolation Essential oil isolation from oregano was performed by hydro distillation in all-glass Clevenger apparatus fol- lowing this procedure: 20 g of the plant material was stored in 500 mL flask where 250 mL of water R was used as distillation liquid and 0.5 mL of xylene R was added in the graduate tube. The Distillation was per- formed for 2.5 h with a rate of 2 ââ¬â 3 mL/min. GC and GC-MS analyses: Agilent 7890à Gas Chro- matography system equipped with flame ionization de- tector (FID) and Agilent 5975C Mass Quadrupole detec- tor as well as capillary flow technology which enable simultaneous analysis of the sample on both detectors. HP-5 ms (30 m Ãâ" 0.25 mm, film thickness 0.25 ï m) cap- illary column was used. Operating conditions were as follows: GC Method for essential oils: oven temperature 60à °C (0 min), 3à °C/min to 240à °C (held for 1 min) and 10à °C/min to 280à °C (held for 1 min); helium as carrier gas at a flow rate of 1 mL/min; injector T = 220à °C and FID T = 270à °C. 1 ï L of injection volume was injected at split ratio 1:1.

Statistical Analyses All statistical analyses were performed with the SPSS software (version 15.0, SPSS) [14]. Means values and variation coefficients were used in the statistical analyses. Effects of the studied traits were evaluated by ANOVA. In order to assess the differentiation of plants of oregano based on all variables that were measured, the Canonical Discriminate Analyses (CDA) was applied Psidium guajava (Guava): Chronic degenerative diseases have reached epidemic proportions in industrialized and developing countries. Many studies have shown that plant can be helpful to prevent or treat diseases. Psidium guajava is a small medicinal tree that is native to South America and Brazil is among the worldââ¬â¢s top producers and most of the countryââ¬â¢s production is destined for the food industry. It is popularly known as guava and has been used traditionally as a medicinal plant throughout the world for a number of ailments. The aim of this review is to present some chemical compounds in P. guajava and their pharmacological effects. The main constituents of guava leaves are phenolic compounds, isoflavonoids, gallic acid, catechin, epicathechin, rutin, naringenin, kaempferol. The pulp is rich in ascorbic acid, carotenoids (lycopene, à ²-carotene and à ²-cryptoxanthin). The seeds,à skin and barks possess glycosids, carotenoids and phenolic compounds. All parts of the plant have been used for different purposes: hepatoprotection, antioxidant, anti-inflammatory, antispasmodic, anti-cancer, antimicrobial, anti-hyperglycemic, analgesic, endothelial progenitor cells, anti-stomachache and anti-diarrhea. P. guajava has many effects on health and that it should be researched more extensively in clinical trials. Furthermore leaves, seeds and peel are treated as wastes by the food processing industry and are discarded, so their use may reduce the disposal of these parts of guava as pollutants. Psidium guajava; Anti-inflammatory; Antioxidant; Cancer; Diabetes; Dyslipidemia Industrialization has led to many modifications in the lifestyle of the worldââ¬â¢s populations, giving rise to increase the indices of several diseases, including chronic degenerative diseases such as insulin resistance, diabetes mellitus, dyslipidemia, metabolic syndrome and cardiovascular diseases, reducing the quality of life and increasing costs on hospitalizations, medications and other public health interventions. Studies have demonstrated that the consumption of fruits, vegetables and seeds can be helpful to prevent the risk factors of many diseases due to the bioactive compounds. Many plants have been used for the purpose of reducing risk factors associated with the occurrence of chronic disorders and for many other purposes Psidium guajava L. is a small medicinal tree that is native to South America. It is popularly known as guava (family Myrtaceae) and has been used traditionally as a medicinal plant throughout the world for a number of ailments. There are two most common varieties of guava: the red (P. guajava var. pomifera) and the white (P. guajava var. pyrifera) All parts of this tree, including fruits, leaves, bark, and roots, have beenà used for treating stomachache and diarrhea in many countries. Leaves, pulp and seeds are used to treat respiratory and gastrointestinal disorders, and as an antispasmodic, anti-inflammatory, as a cough sedative, anti-diarrheic, in the management of hypertension, obesity and in the control of diabetes mellitus. It also possesses anticancer properties . The seeds are used as antimicrobial, gastrointestinal, anti-allergic and anticarcinogenic activity. Brazil is among the worldââ¬â¢s top producers of guava and most of the countryââ¬â¢s production is destined for the food industry to produce candies, juices, jams and frozen pulp. As result of the fruit process there is a discard of the leaves, seeds, part of the peel and pulp fraction not separated in the physical depulping process. The high cost of pharmaceutical medications conduces to the search for alternative medicines to treat many ailments. In view of this, studies are necessary to confirm the effects of medicinal plants. The aim of this review is to show that several studies have demonstrated the presence of many different chemical compounds in P. guajava and their pharmacological effects. Medical Properties and Composition of Guava Pulp The main constituents of guava are vitamins, tanins, phenolic compounds, flavonoids, essential oils, sesquiterpene alcohols and triterpenoid acids. These and other compounds are related to many health effects of guava . Some authors have found high concentrations of carotenoids (beta-carotene, lycopene, and beta-cryptoxanthin), vitamin C and polyphenols in guava pulp. Lycopene has been correlated with the prevention of cardiovascular damage because of its positive effects on dyslipidemia . Ascorbic acid is recognized for its important antioxidant effects . Shu et al. isolated nine triterpenoids from guava fruit: ursolic acid; 1beta, 3beta-dihydroxyurs-12-en-28-oic acid; 2alpha,3beta-dihydroxyurs-à 12-en-28-oic acid; 3beta,19alpha-dihydroxyurs-12en-28-oic acid; 19a-hydroxylurs-12-en-28-oic acid-3-O-alpha-L-arabinopyrano- side; 3beta, 23-dihydroxy urs-12-en-28-oic acid; 3beta, 19alpha, 23beta- tri-hydroxylurs-12-en-28-oic acid; 2alpha, 3beta,19alpha, 23beta-tetrahydroxyurs-12-en-28-oic acid and 3alpha,19alpha,23,24-tetrahydroxyurs -12-en-28-oic acid. Ursolic acid and other triterpenoids are associated with anti-cancer properties. Shu et al. found three benzophenone glycosides in ripe edible fruits of P. guajava L: 2, 6-dihydroxy-3, 5-dimethyl-4-O-beta-D-glucopyranosyl-benzophenone; 2, 6-dihydroxy-3-methyl-4-O-(6ââ¬â¢Ã¢â¬â¢-O-galloyl-beta-D-glucopyranosyl)-benzophenone and 2, 6-dihydroxy-3, 5-dimethyl-4-O-(6ââ¬â¢Ã¢â¬â¢-O-galloyl-beta-D-glucopyranosyl)-benzophenone. Benzophenone glycosides have inhibitory effect on triglycerides accumulation. Thuaytong and Anprung found antioxidant activity in guava and the major constituents identified in white and red guavas were ascorbic acid, gallic acid, catechin equivalents, cinnamyl alcohol, ethyl benzoate, ß-caryophyllene, (E)-3-hexenyl acetate and à ±-bisabolene. The antioxidant properties of the guava pulp can be related to anti-cancer effects. Studies with humans have found that the consumption of guava for a period of 12 weeks reduced blood pressure by 8%, total cholesterol levels by 9%, triacylglycerides by almost 8%, and induced an 8% increase in the levels of HDL-c. Farinazzi et al.showed that animals treated with guava pulp juice had significantly lower body weight, glycemia, cholesterol and triglycerides levels and significantly augmented the levels of HDL-c when compared to the animals from the control group. Lyophilized pulp of P. guajava in diabetic rats induces to significant hypoglycemic effects probably due to its antioxidant activity of compounds present in the pulp. Medical Properties and Composition of Guava Leaves Guava leaf extract has analgesic, anti-inflammatory, antimicrobial, hepatoprotective and antioxidant activities. These effects are probably due to the presence of phenolic compounds. à Jimà ©nez-Escrig et al., Wang et al. and Haida et. reported the presence of higher amounts of phenolic compounds with antioxidant activity in the leaves of white (Psidium guajava var. pyrifera L.) and red guava (Psidium guajava var. pomifera L.) when compared with other vegetable species. Wu et al, Melo et al. and Chen et al found gallic acid, catechins, epicatechins, rutin, naringenin and kaempferol in the leaves. Studies have shown that gallic acid, catechin, and epicatechin inhibit pancreatic cholesterol esterase, which decreases cholesterol levels. Catechins are important as a preventive treatment for diabetes type 2 and obesity. Quercetin has been associated to decreased mortality from heart disease and decreased incidence of stroke. Quercetin presents hypocholesterolemic and antioxidant activity. Rutin is effective in the inhibition of triglyceride accumulation in adipocytes. Naringenin and kaempferol can promote moderate cytostatic activity against all cell lines and kaempferol can be useful as anticancer . Fu et al.elucidated the structure of three novel sesquiterpenoid- based meroterpenoids of psidials A-C found in guava leaves. Matsuzak et al.isolated two new benzophenone galloyl glycosides, guavinosides A and B, and a quercetin galloyl glycoside, guavinoside C as well as five known quercetin glycosides from guava leaves. The structures of the novel glycosides were elucidated to be 2,4,6-trihydroxybenzophenone 4-O-(6ââ¬â¢Ã¢â¬â¢-O-galloyl)-beta-D: -glucopyranoside (1, guavinoside A); 2,4,6-trihydroxy-3,5-dimethylbenzophenone 4-O-(6ââ¬â¢Ã¢â¬â¢-O-galloyl)-beta-D: -glucopyranoside (2, guavinoside B), and quercetin 3-O-(5ââ¬â¢Ã¢â¬â¢-O-galloyl)-alpha-L: -arabinofuranoside (3, guavinoside C). Kim et al.related that the guava leaves contain ascorbic acid, citric acid,à acetic acid, epicatechin, xanthine, protocatechuic acid, glutamic acid, asparagine, malonic acid, trans-aconitic acid, maleic acid and cis-aconitic acid. Ghosh et al.isolated two terpenoids from the leaf extract of P. guajava (betulinic acid and lupeol) and reported their potential antimicrobial and phytotoxic activities. Betulinic acid and lupeol can be used in the treatment of diabetes, cardiovascular desease, obesity and atherosclerosis. Shao et al. isolated two terpenoids from guava leaves: Psiguadials A and B, two novel sesquiterpenoid-diphenylmethane meroterpenoids with unusual skeletons, along with a pair of known epimers, psidial A and guajadial. Shu et al.identified one diphenylmethane, one benzophenone, and eight flavonoids from guava fresh leaves(2,6-dihydroxy-3-formaldehyde-5-methyl-4-O-(6â⬠³-O-galloyl-à ²-D-glucopyranosyl)-diphenylmethane; 2,6-dihydroxy-3,5-dimethyl-4-O-(6â⬠³-O-galloyl-à ²-D-glucopyranosyl)-benzophenone; kaempferol; quercetin; quercitrin; isoquercitrin; guaijaverin; avicularin; hyperoside and reynoutrin. Guaijaverin has high potential antiplaque agent by inhibiting the growth of the Streptococcus mutans. Avicularin and guaijaverin work as urease inhibitors (against Helicobacter pylori urease). Shao et al. isolated four new triterpenoids, psiguanins A-D (1-4), and with 13 known compounds from the leaves of guava. à Guava aqueous leaf extract showed anti-trypanosomal properties in rats experimentally infected with Trypanosoma brucei brucei. à Rahim et al.evaluated the effects of aqueous mixture and water soluble methanol extract from guava leaves and bark against multi-drug-resistant Vibrio cholera and found strong antibacterial activity. They concluded that this plant offers potential for controlling epidemics of cholera. Birdi et al. and Birdi et al. related that P. guajava leaves have a broad spectrum of antimicrobial action (as antigiardial and antirotaviral activity) that could be effective in controlling diarrhea due to a wide range of pathogens. The antimicrobial activity can be linked to the presence of flavonoidsà extracted from guava leaves. Deguchi and Miyazaki reported that guava leaves infusion not only reduced postprandial glycemia and improved hyperinsulinemia in murine models but also contributed to reduce hypercholesterolemia, hypertriglyceridemia and hypoadiponectinemia in the animals of their study. Rutin and kaempferol found in guava leaves are compounds related to the decrease of HMG-CoA reductase activity in hepatic tissue and improve lipid profiles. Akinmoladun et al. studied methanol extracts of some fruits, including P. guajava, and demonstrated that there is a good correlation between total phenolic contents and reductive potential and a fair correlation between total phenolic contents and lipid peroxidation inhibitory activity. Several studies have shown that aqueous extract of Psidium guajava contains components with LDL-c antiglycation activity, suggesting its contribution to the prevention of neurodegenerative and cardiovascular diseases Other studies have found cardioprotective effects of aqueous extract of P. guajava in myocardial ischemia-reperfusion injury in isolated rat hearts, primarily through their radical-scavenging actions. Ojewole identified the presence of phenolic compounds in the leaves demonstrating their hypoglycemic and hypotensive effects on diabetic rats treated with aqueous leaf extract. Soman et al. reported a decline in the levels of glycated hemoglobin and fructosamines, as well as a significant reduction in the glycemic levels of diabetic rats treated with guava leaf extract. Singh and Marar studied the effects of Psidium guajava leaves on the inhibition of the activity intestinal glycosidases related with postprandial hyperglycemia, suggesting its use for the treatment of individuals with type 2 diabetes.Other studies have demonstrated that guava leaf and peel extracts also had hypoglycemic effects on experimental models drug-induced to severe conditions of diabetes. Wu et al.found that the phenolic compounds, gallic acid, catechins andà quercetins in guava leaves inhibited the glycation of proteins suggesting its use for the prevention of diabetes complications.The Psiguadials A, B and guajadial isolated by Shao et al. exhibited potent inhibitory effects on the growth of human hepatoma cells. Kim et al. related that the guava leaves contain compounds that promote free radical scavenging activity showing promising antioxidant properties. Dutta and Das identified significant anti-inflammatory activity of the ethanol extract of guava leaves in experimental models, while Kawakami et al. observed the antiproliferative activity of the leaves through inhibition of the catalytic activity of prostaglandin endoperoxide H synthases involved in the inflammatory process. Guava budding leaves aqueous extract possesses an extremely high content of poly phenolic and isoflavonoids and suppresses the cell migration and the angiogenesis. In view of this, clinically it has the potential to be used as an adjuvant anti-cancer chemo preventive . Matsuzak et al. isolated phenolic glycosides from guava leaves and showed significant inhibitory activity against histamine release from rat peritoneal mast cells, and nitric oxide production from a murine macrophage-like cell line. Roy and Das studied the hepatoprotective activity of different extracts of P. guajava (petroleum ether, chloroform, ethyl acetate, methanol and aqueous) in acute experimental liver injury induced by carbon tetrachloride and paracetamol. The effects were compared with a known hepatoprotective agent and observed that the best effects came from guava methanolic leaf extract that significantly reduced the elevated serum levels of enzymes (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase) and bilirubin. P. guajava leaves exhibit high capacity to reduced polymerization and aggregation of sickle cell hemoglobin molecule. This molecule is a product of a defective genetic code of hemoglobin molecule and is prone to deoxygenation-induced polymerization and has low insolubility. The development of chemical modification agents that reduce the tendency of sickle cell hemoglobin molecule to aggregate represents an importantà chemotherapeutic goal. Guava extract leaves can be responsible for membrane stabilizing effect on sickle erythrocytes that are susceptible to endogenous free radical-mediated oxidative damage. This effect can be attributed to the flavonoids, triterpenoids and host of other secondary plant metabolites . Chen et al. found that aqueous extract of guava budding leaves possess anti-prostate cancer activity in a cell line model and concluded they are promising anti-androgen-sensitive prostate cancer agent. Han et al. studied the effects of P. guajava ethyl acetate extract on atopic dermatitis and found that it inhibits chemokine expression in keratinocytes what suggests this extract can have possible therapeutic application in atopic dermatitis and other inflammatory skin diseases. Methanol extracts of the leaves can also be useful in the treatment of gastric ulcer disorders possibly due to the presence of volatile oil, flavonoids and saponins Methanolic extract of guava leaves can exhibit wound healing effects and this property can be explained by the presence of tannins and flavonoids. Guava leaves extract also can show anti cough effects as shown by Jaiarj et al. Medical Properties and Composition of Guava Discarded Products As told before, the fruit process results in the discard of the leaves, seeds, part of the peel and pulp. Some studies showed the presence of total phenolic compounds in the agroindustrial wastes (seeds, skin and pulp) of guava, confirming its antioxidant activity . Leaves, seeds and peels of fruits have significant proportions of bioactive compounds with beneficial physiological and metabolic properties. Its antioxidants can control body weight and biochemical variables like glycemia, dyslipidemia, hypertension and other risks of cardiovascular diseases. The antioxidant properties of the guava seeds extracts can be associated to anti-cancer effects on both hematological and solid neoplasmsà and the antioxidant properties of the guava peel can be related to anti-cancer effects. Castro-Vargas et al.and Ojewole extracted and identified significant levels of carotenoids and total phenolic compounds from guava seeds. Seeds exhibit antimicrobial, gastrointestinal and anticarcinogenic activities probably due to the presence of phenolic glycosides in the composition. Farinazzi et al. showed that Wistar rats treated with guava seed had significantly lower glycemia, cholesterol and triglycerides levels and body weight. These animals significantly increased HDL-c levels. Rai et al. reported hypolipidemic and hepatoprotective effects in diabetic rats treated with aqueous extract of lyophilized guava peel. à Psidium guajava stem-bark extract can be used to treat malaria because it presents antiplasmodial activities possibly due to the presence of anthraquinones, flavonoids, seccoirridoids and terpenoids. Related study Many researchers have been demonstrating the presence of a wide variety of bioactive compounds in the leaf, seed and bark of Psidium guajava that are capable of showing beneficial effects on human health. If we consider that chronic degenerative diseases have reached epidemic proportions in many countries and increase the socio-economic burden for the public health system, it is necessary to find non-allopathic alternatives that minimize risk factors of these diseases and help in the treatment. Furthermore, population consumes medicinal plants also to treat other kind or diseases because of high costs of allopathic medications. The studies using P. guajava bring information that may provide validation for its medicinal uses but it should be researched more extensively in clinical trials so it could be used for prevention and as an adjuvant in the treatment of numerous disorders. Nevertheless we should emphasize the importance of experimental and clinicalà studies involving more specific factors related to the bioavailability of the compounds, as well as the effective and safe doses to be used by individuals for the prevention and treatment of various disorders.
