Malaria - Research Paper Essays - Plasmodium, Malaria, Apicomplexa

Malaria - Research Paper Research Paper- Malaria Malaria is a disease caused by a parasite that lives both in mosquitoes and humans (9). Malaria lives in tropical and sub-tropical areas such as Southeast Asia, the Middle East, Haiti, India, The Dominican Republic, Africa, Papua New Guinea, and Central and South America (3). Malaria is one of the largest diseases around the world. About one out of every 20 people on earth, almost 300 million people, suffer from malaria yearly. Almost 2 million of those 300 million people die each year. Many new drugs are being tested to prevent malaria but no sure vaccine has been discovered (1). Malaria has terrorized this earth since the mid-Pleistocene age. No one knows just when malaria showed up in the Western Hemisphere however. Many say that malaria roamed the New World before the Europeans came over. Yet others will tell you that the Western Hemisphere had no contact with malaria until the end of the fifteenth century. Many other diseases similar in destruction as malaria were brought over from the old world from Europe and Africa (5). Malaria limited colonization all over the world. West Africa and Northern Australia were major hot spot for malaria attacks during the colonization of those areas. Malaria also resulted in many casualties in wars form Ancient Greece to Vietnam and present (2). The Old World supposedly gave malaria to the New World. However, the New World found the first effective treatment for the disease. In 1632, a piece of bark form a Peruvian Tree was taken to Europe by a Spanish priest. The bark was soon found to be a remedy to the constant fevers. Malaria was extremely active in Ancient Rome and Europe. However, it is proven that the malaria back then was much less destructive than it has been in recent centuries. This is because P. falciparum, the most deadly type of malaria, was not present back in Ancient Europe. After the fall of the Roman Empire, the History of malaria is unknown for quite some time in Ancient Europe. It was not until the seventeenth and eighteenth centuries that malaria became a problem again in Europe. The Netherlands, southern Scandinavia, Poland and Russia all experienced malaria terror. Ronald Ross was the first man to reveal the development of the malarial parasite in the mosquito (5). The new era of malariology came in the last two decades of the nineteenth century (5). Earlier theories on malaria included an idea by Alphonse Laveran in 1880, who claimed that malaria came form the mud. Malaria was often thought of as coming form bad air as well. No one knew what it cam from, they just new it was present in swamps were there was mud and bad air. However, this new era included the idea that parasites were the root to malaria. This idea is what Ronald Ross had explained. (2). This new era led to the new ideas for malaria control, which took place in the first couple of decades of the twentieth century. Malaria control was strengthened in the 1930's when synthetic antimalarials. They were very useful in the treatment of malaria. In the 1940's DDT was introduced. This was the first pesticide to be used in order to kill mosquitoes (5). This new pesticide led people to believe that with the right malaria control they could wipe out malaria. DDT was extremely successful e specially in India where a DDT spraying program brought malaria cases down by thousands in 1950. Then the mosquitoes became immune to DDT, DDT became expensive, and India had a great big problem all over again. From 1920 to 1950 antibiotics were the most widely used and best treatment for malaria. Since then, no new history has been made. The US Government continues to spend very low income on malaria research and we still have a malaria problem today (2). There are four kinds of malaria that infect humans. P. falciparum, P. vivax, P. ovale, and P. malariae are the four diseases humans are endanger of getting. The most severe of them all is P. falciparum. P. falciparum has horrible effects. The effects include fever and chills occurring at irregular intervals. P. vivax is the most common

David Awaiting Goliath essays

David Awaiting Goliath essays Before going to Eleganza, the only sculpture that I had ever seen, besides the small statues in neighbors' yards, was in books that I had looked at. When I entered the museum I noticed the many sculptures that occupied the small space. After walking around, observing the different sculptures and listening to Dr. Roselle speak, I came to a decision that David was my favorite statue in the museum. The complexity, texture, and realistic characteristics of Michelangelo's David made this a beautiful sculpture. I had only been exposed to pictures in books of sculpture before visiting Eleganza. For me to be able to see the sculptures in their three-dimensional form right in front of me was an experience I had never thought that I would have, unless I traveled to Europe. David's body structure looked so firm and strong. I gained much respect for Michelangelo after hearing the stories Dr. Roselle told about his remarkable success in sculpting. It is hard for me to imagine the tools used to create the intricate details existed back when Michelangelo was working on his sculptures. The texture of David was smooth to the touch; every curve seemed to flow with the rest of the body structure. The ivory color of the statue was pleasing to the eye and gave the statue even more of a soft, smooth texture. I was very pleased with the fact that I was allowed to touch David to feel the texture for myself. One thing that I noticed that seemed to stand out to me about all of the statues was that all of the toes were exceptionally long. David's appearance was that exactly of a human being; I observed the body and there wasn't a flaw to be found. The realness found in looking at David was astonishing. Everything from the muscles in his arms and stomach to the curl in his hair made him an exceptional piece of art. Unlike a lot of the Greek sculpture, of gods, David is constructed as a young man that s ...

Discrimination in hispanic business Research Paper - 1

Discrimination in hispanic business - Research Paper Example The majority of the Hispanic business owners underline that employees in their companies are lacking of management skills. There is no essential source of financing directed on employees skills development. On the one hand, it is rather effective to promote Hispanic business in case of employees are of Hispanic origin, because very often non-Hispanics are not hired as a major part of employees. Hispanic business owners are prevented from private and public market options. A great number of respondents agree upon the fact that the government does not give them an equal opportunity for business development and promotion. There are many cases, when Hispanic business owners were oppressed and discriminated. One of the main examples is the following: "Latino business owners in Queens have complained that they feel discriminated against by Community Board 3 when they apply for licenses to sell alcohol" (Medina, 2012). There is a clear rejection in license because of business owners Hispanic origin. Palagauchi accuses government of racial prejudices. He underlines that Hispanic business owners know English and they can be good specialists, but they can find no help. The government remains silent. Other businessmen of Hispanic origin underlined that a hostile mood, an aggressive behavior, total prejudice and abuse were experienced by them in the process of documents collecting and applying for alcohol trade license. Very often people in different business fields are complaining about a cruel attitude. It is necessary to introduce new perspectives and the new waves of immigrants of Hispanic origin to America are also looking forward to finding new ways of personal realization of business goals. On the one hand, America is a big country and there are many different options for realization of goals of these people. As a matter of fact, ethnic minorities are exposed to
