“The development of a genetic vaccine against malaria, its mode of administration, and its possible mode of action. “

Malaria is a desease in which there are vast research studies going on to develop a vaccine. Malaria is a life threatening desease caused by paprasites that are transmitted to people by the bite of an infected mosquito. Malaria is preventable and curable however there is no effective vaccine in place. Malaria kills about one million people each year. The hardest hit is countries that are undeveloped like Africa. The children of Africa are the most vulnerable due to the poverty: no food and dirty water. Dirty swampy water is breeding gound for mosquitos. 1 in every 5 childhood deaths is due to malaria and its effect of the desease. In my research of this desease I came across PATH Malaria Vaccine Iniative. They work in connections with GSK(GlaxoSmithKline) who have developed the Vaccine RTS,S/AS for the treatment of Malaria. GSK is one of the worlds leading research Pharmacuetical headcare companies. They have been working on the improving the Vaccine since 1980 and have finished with PhaseII test study. They did this study in children ages 1-4 and adminisitered the vaccine along with child vaccinations that they would normally get. The study came back positve and they saw a decline in the study group that clinical Malaria incidents were down. The RTS,S/AS is administered intradermally with a needle. They are currently getting ready to go into Phase III.
“While drugs, insecticide-treated bednets, and other interventions are currently being used to help reduce malaria’s impact, the parasite is complex and adaptable, and it has survived for millennia. We need many tools to defeat this disease—tools that save lives today and those with the potential to save lives in the future. A safe…...

Seed in Bangladesh

...INTRODUCTION Seed is an important vehicle for technological innovations. And good seed is one of the first and foremost prerequisites for a healthy and vigorous crop. However, seed is more than an agricultural input and a source of new technologies. A range of developmental, socio-economic, environmental and political issues are also covered by seed: food security, natural resource management, agro biodiversity, intellectual property rights, social dynamics, gender, cultural and religious dimensions, policies and regulations. And seed technology is the total of all the systematic activities necessary for production and supply of quality seeds in the crop culture of a country. These systematic activities are: multiplication, processing and preservation, quality assurance, marketing and finally ensuring the use of seed by farmers. The sequential approach in ensuring the use of quality seed has been undertaken in mid seventies and the quantity of seeds supplied by following the seed technological activities is only 6% of the total requirement. Rest of the seed used in the country is almost of unknown quality. Researches undertaken in these areas are inadequate and fragmentary. History of Seed System Development Traditionally, farmers keep a part of their produce as seed and use it for subsequent crop production. They also collect seed from their neighbors’ when necessary. Seeds were also sold in village markets. Seed...

Fruit & Seed Dispersal

...Fruit & Seed Dispersal Fruits and seeds are a very important component to the longevity of human race. They are a very important source of nutrients that one has to intake to stay vital in their everyday life. The dispersal of fruits and seeds are factors that distributed in many ways. Seeds are dispersed in many ways by the wind, human dispersal, and animal dispersal are sources that contribute to very favorable environment for plants to flourish, and be able to grow. In order for plants to be able to survive, and grow they need to be in a separate environment from the parent plant so that they are able to thrive, and not become overcrowded. Essentially, a seed consists of a miniature undeveloped plant which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat. Frequently small in size and making negligible demands upon their environment, seeds are eminently suited to perform a wide variety of functions the relationships of which are not always obvious: multiplication, perennation, dormancy and dispersal. (Britannica Online seed and fruit 2012). Why are some fruits sweet and some sour, whereas others have no specific taste? The taste of fruits depend on a lot factors such as the chemistry of the plant where it is derived from, how much glucose that may be in the particular fruits as many fruits are made up of many ingredients such has vitamin fructose, acids, vitamins, starch, proteins and cellulose...

The Bad Seed

...Landon White Mrs. Morgan Theatre 1 October 9, 2012 The Bad Seed The bad seed is about a young girl. Her family is rich and her aunt spoils her to no end. She likes jewelry. She goes to a manners class. The mother of this girl is very protective and doesn’t like the aunt to spoil her daughter. One Sunday evening, the daughter is at a manners picnic and the mother and aunt are at home. They here on the radio that an eight year old child has drowned. The mom starts to panic. The aunt tells her that her daughter is too smart to do something like that. The radio said they would contact the parents of the child before they gave out the child’s name to the public. After that they never receive a phone call. Later that night they hear it was an eight year old boy. Her daughter comes home on the bus and acts like nothing is affecting her at all. The mom tells her not to be scared of drowning because of the accident that had just happened. The daughter told her mom that she wasn’t afraid of what had happened at all. This bothers the mother a little bit. The daughter is very proper and has a cocky attitude. She is mean to the person that cleans their house. The person that cleans their house is very creepy and talks about when he and the little girl’s aunt are alone at the house. I didn’t get to see the end of the movie but I think the little girl pushed the boy that drowned into the water and stole the jewelry that was on him. I also think that in the end of the story the man......

Seed Saving 101

...We’re coasting out of summer. At first, it seemed like it would never arrive; now, it seems to be clawing at the rim, refusing to leave. Soon enough, the main gardening activity we’ll all be doing is poring over seed catalogs, dreaming of warm summer days and freshly-picked produce from the garden. Right now is a great time to save the seeds of the best-producing of those veggies from this year’s garden. Why pay a seed company 65 cents a seed for a tomato seed when you can save for yourself and your gardening friends (and drop off a few in the Wimer Seed Library) with just a few minutes work. There is also the huge satisfaction of completing the circle from seed to harvest and back to seed again – SUSTAINABILITY! If providing an entire meal at this time of year with vegetables grown less than 100 feet from your back door, then how much more local it is to use vegetables where the seed never came from more than 100 feet away! There is nearly a mystique about sustainability and propagating life, whether human, animal or plant. With plants, the work is almost unquestioningly left to ‘experts’, even though the processes are natural and have gone on since time immemorial. “Experts” may have their place, but when it comes to the incredible variety of vegetables available, backyard seed-savers also deserve due recognition. Saving the seed from any heirloom vegetable is easy. If you have a favorite variety, or even just want to try seed saving for the fun of it...

Seed Dormancy

...INTRODUCTION Seed dormancy refers to a state in which viable seeds fail to germinate when provided with conditions normally favourable to germination i.e adequate moisture, appropriate temperature regime, a normal atmosphere and in some cases light. Dormancy has evolved as a strategy to avoid germination under conditions where seedlings survival is likely to be low. Despite the fact that many researchers study dormancy, there is no unambiguous definition of the phenomenon, perhaps because it manifest and broken in different ways in different species( Bewley and Black,1994; Vleeshouwers et al.; Lange ,1996). It is a condition in which seeds will not germinate even when the conditions are permissive for germination (Braford et al;1994).This not only prevent immediate germination but also regulates the time, condition and place that germination will occur. In plant physiology, dormancy is a survival strategy exhibited by many plant species which enable them to survive in climate where part of the year is unsuitable for growth ( Crowe and Crowe,1992). Seed dormancy is nature’s way of setting a time clock that allows the seed to initiate germination when condition are favourable for germination and survival of the seedlings. Dormancy in seeds may be advantageous or problematic during seed handling . The advantage is that it prevents seeds from germinating during storage and other handling procedures, and induction of dormancy, for example by drying and...

Essay: the Bad Seed

...The world itself is full of people and the secrets hidden within. A prime example of this are from books like The Bad Seed by William March and We Have Always Lived in the Castle by Shirley Jackson. These two novels both contain characters with many secrets, many dark secrets that cause them to hide and live away from society. In a sense, these characters live in “secret worlds”. Starting off with The Bad Seed, Rhoda, the main character who is responsible for violent crimes and her mother Christine who is the “guardian angel” that’s responsible for keeping Rhoda out of trouble. Just like Rhoda, the character Merricat from We Have Always Lived in the Castle is the one causing the trouble and her sister Constance is the protector. The dark secrets of both Rhoda and Merricat involving murder provide reasons as to why they separate themselves from society, why this secrecy leads them to perversity and violence and why the emotions felt within encourage this life of secrecy. Both characters live in a world where they have a difficult time adapting to society and life problems. As a result, they do what they feel is needed even if it involves performing murderous actions. The secrecy deep within the characters lead to violence and is probably due to the fact that they don’t have the support that they need. For instance in Rhoda’s situation, her father Kenneth leaves at the beginning of the novel and heads out on a business trip. This leaves her to mainly rely on her mother...

Seed Germination

...1 (1) (2) Physiology of Seed Germination Miller B. McDonald Seed Biology Program Department of Horticulture and Crop Science The Ohio State University Columbus, OH 43210-1086 mcdonald.2@osu.edu (3) In the germination process, the seed’s role is that of a reproductive unit; it is the thread of life that assures survival of all plant species. Furthermore, because of its role in stand establishment, seed germination remains a key to modern agriculture. Thus, especially in a world acutely aware of the delicate balance between food production and world population, a fundamental understanding of germination is essential to crop production. (4) Definition of Seed Germination. Various definitions of seed germination have been proposed, and it is important to understand their distinctions. The the seed physiologist, germination is defined as the emergence of the radicle through the seed coat. Such a definition says nothing about other essential structures such as the epicotyl or hypocotyls that become the above ground parts of a successful seedling. To the seed analyst, germination is “the emergence and development from the seed embryo of those essential structures which, for the kind of seed in question, are indicative of the ability to produce a normal plant under favorable conditions.” This definition focuses on the reproductive ability of the seed, an essential objective in agriculture. Does it have the capacity to produce a normal plant? Others consider germination to be the...

Pepper Seed Dna Extraction

...Pepper Seed DNA Extraction Biochem lab: CHE 452L marisol gomez Pepper Seed DNA Extraction Biochem lab: CHE 452L marisol gomez 2015 2015 INTRODUCTION The jalapeno is a member of the capsicum family, along with many other peppers. The usual methods for characterization of different pepper species are based on their morphological and physiological traits, however this many not always be enough. For peppers, their traits are influenced by things like their genotype or their specific environment. Genomic markers can allow for a more direct comparison of closely related individuals (Ansari and Khan, 2012). In our case we focus on DNA extraction. The two basic parts of a DNA extraction procedure include the breaking of the cell walls to expose the DNA and the use of enzymes to remove contaminants. The DNA is analyzed for purity by taking the absorbance. The pure DNA is then visualized by gel electrophoresis. The DNA extraction of plant seeds is difficult because of their cell wall. The method used to break the cell wall includes grinding the seeds with liquid nitrogen. The addition of DNAzol is used to isolate genomic DNA (Chomczynski et al. 1997). Restriction enzymes are necessary to fragment patterns of the DNA and in turn making it easier to analyze the DNA through gel electrophoresis. BACKGROUND The purpose of our experiment is to extract the DNA from pepper seeds to be able to compare and contrast the similarities in their DNA. The extraction of DNA from a...
