The tsetse fly is predominant found in large areas of sub-Saharan Africa where there is human settlement and agriculture. The tsetse flies are cousins of the house fly, however they are larger than a common house fly. Approximate length of a house fly is 6 to 7 mm while a tsetse fly ranges anywhere from 6 to 16 mm in length. There are approximately 22 different kinds or species of tsetse fly living on the continent of Africa presently. The scientific name for the tsetse fly is Glossina. Each of the different species of a tsetse fly has its own identifying name following the name Glossina. The generic or genus name is Glossina, A genus is a group of closely related species. The name that follows is the name of the species, or the specific name. For example, the Glossina Palpalis.
All of the species of the tsetse fly is generally the same in appearance with their color ranging from a yellowish brown to dark brown. When the tsetse fly is in a resting position the wings are usually flat over the back. One differentiating characteristic of the tsetse fly that distinguish them from other flies are a row of long, branched hairs that is present on each of their antennas.
The average lifespan of a tsetse fly adult ranges from one to three months. The process of reproduction begins with the larva hatching from an egg within the female and the development of the young tsetse occurring within the uterus. The larva growth process usually take about nine days. While in the uterus, the larva get nutrients from fluid secreted from the female tsetse’s uterine wall. Proper nutrition is necessary because if under nourished the female fly will produce a small, underdeveloped and nonviable larva. On the other hand, adequate nutrition will ...

...ecrease the effects of the sleeping sickness and the rate of infection. Organizations such as the World Health Organization have taken the forefront in creating certain partnerships with drug companies to ensure there is available treatment for individuals requiring them; also partnerships was created to allow for a better accountability of the infected subjects, an ensuring they receive the necessary care.
As a young boy growing up, one of my first memories of a science lesson involves learning about the tsetse fly of the Sub Saharan Africa. It fascinated me to know that the fly was capable of putting people to sleep for life with one bite; hence the reason for me choosing the topic for my presentation. By researching this topic, I learned some very interesting information about the species, it definitely gave a larger view of what I thought I knew in my youth.
As of now, many of the sicknesses are completely prevented and controlled. People of today have the conveniency to run to the store or their cabinet, eat a pill, and feel better in a short notice. Most of the time, it goes unnoticed for one to wonder how they would cope with their throbbing h...
“Flight Patterns,” by Sherman Alexie, tells an interesting story of a man named William, who is a Spokane Indian and lives in Washington State with his wife Marie and five-year-old daughter Grace. William struggles with living between the traditionalist American and Indian worlds by appearing confident and assured, but on the inside, he is actually weak, fearful, and has an abundance of obsessions. He loves his job and hates it at the same time, He needs to fly for his job, but flying scares him since the terrorist attacks that happened on September 11th. He seems very indecisive and unassured at times. He stays in the same hotel chain, eats at the same restaurants, and has the same exercise routine while
The Asian Tiger Mosquito looks very similar to our common, everyday mosquitos except for a few differences. This six-legged insect averages a length of about ten millimeters. The abdomen of this species is black with white horizontal bands. These white bands are also found on the legs and have white tips on the palp. The thorax is also black and the dorsal side of the thorax has a white stripe down the center, starting at the back of the head and continues along the thorax.
"In the past two decades or so, health care has been commercialized as never before, and professionalism in medicine seems to be giving way to entrepreneurialism," commented Arnold S. Relman, professor of medicine and social medicine at Harvard Medical School (Wekesser 66). This statement may have a great deal of bearing on reality. The tangled knot of insurers, physicians, drug companies, and hospitals that we call our health system is not as unselfish and focused on the patients' needs as people would like to think. Pharmaceutical companies are particularly ruthless, many of them spending millions of dollars per year to convince doctors to prescribe their drugs and to convince consumers that their specific brand of drug is needed in order to cure their ailments. For instance, they may present symptoms that are perfectly harmless, and lead potential citizens to believe that, because of these symptoms, they are "sick" and in need of medication.
Sherman Alexie’s Flight Patterns tries to tackle a challenging subject. It probes the underbelly of modern life, sifting through the cloudy American mind that’s full of seemingly useless information, in search of what’s truly important in life. This happens through the stories two main scenes. The first depicts William’s relationship with his daughter and wife, and conflicts in life. The second engages William in a taxi-cab conversation that shuffles his priorities and forces him to confront his problem. This pushes him to his tipping point, and when the ride is over, he becomes uneasy and cares only to hear his family’s voice, not about his job, or the fears that had previously been driving forces. Alexie is trying to show that temporary concerns should never come before a thing like family, something that will remain permanent.
...influenza pandemic in one way or another; the use of quarantines were extremely prevalent among them. Also, the pandemic is directly responsible for the creation of many health organizations across the globe. The organizations help track and research illnesses across the globe. The CDC (Centers for Disease Control and Prevention) for example, strive to prevent epidemics and pandemics. They also provide a governing body with directives to follow in case an outbreak does occur, and if one shall occur the efforts of organizations across the globe will be crucial for its containment. It is amazing that with modern medicine and proper organization that influenza still manages to make its appearance across the globe annually.
This relates strongly with my long term professional goals. In the long run, I really wish to help as many people as I can by advancing pharmacy. It is a dream to be able to go to a developing country or be part of an organization such as the World Health Organization and spread the knowledge of pharmacy and bring h...
There are nearly one million species of insects known. Insects are defined by having six legs and a body divided into three segments: head, thorax, and abdomen. Chitin is an organic material that makes up an insects exoskeleton. There are three life cycles of insects, ametabolous or incomplete and paurometabolous or gradual, and homotabolous or complete metamorphosis. These life cycles are important in the aging of insects for aiding in legal investigations, (Houck and Siegel. Entomology).
The pharmaceutical and biotech industries must be free to develop and research life saving medicines and other advancements that will benefit society. If this cannot be done, progress would never be made. People would still be contracting polio a...
The cicada is a stout, black insect about an inch in length. Various species of this insect can be found all over North of the America. When the cicada is at rest, its large, transparent, veined wings are folded over the top of its body and extend about a quarter of an inch beyond it. Cicada wing veins are and information reddish orange in color, as are its eyes and legs. The front legs are sharp and crablike, allowing the animal to hold tight to the bark of trees. The species of American cicada most written about by scientists and most wondered about by the general public is known as the periodical cicada. Its scientific name is Magicicada septendecim. This species of cicada appears above ground only once every seventeen years.
They are very popular because they have a relatively short life cycle, which lasts about 9 days. This makes it easy to observe multiple generations in a short period of time. The fly’s life cycle consists of egg, larvae, pupa, and adult stages. At each of these stages of development, Drosophila exhibits different phonotypical identities and mutations. The flies that were crossed contained a genetic mutation called apterous. Apterous can be observed by looking for flied that are missing wings. Flies with apterous will not have any wings. If this mutation is sex linked, it is expected that the male population will only be wingless in the F2 generation. If the mutational is autosomal, it is expected that the mutation to normal fly ratio is
...f ivermectin in the first place. Furthermore, we wouldn’t want to risk Merck going out of business, as it seems they had the capability to produce many useful medications. They’d already proved to make six useful, safe, and powerful drugs—the medical world wouldn’t want to lose such able creators. The best choice, therefore, would have Merck contributing to the research, but include other pharmaceutical companies and private donors to help with the financial and personnel costs. This funding would allow Merck and the other companies to sell at low costs, or even give, the medication to those who desperately need it. In order to implement such this type of plan, Merck would have to take the lead. They would have to actively seek out organizations, companies and private donors and explain the wonderful consequences for huge populations with the success of ivermectin.
Sherman Alexie’s short story “Flight Patterns” is an intriguing story about many themes, including identity, stereotypes, and the illusions of society. The story is written from an American Indian’s viewpoint and provides and interesting and different perspective on identities and relations in America after the terrorist attack on Spetember 11, 2001. The main character William, a native American man who has a wife and a daughter named Marie and Grace respectively, leaves his family for a business trip. On his way to the airport, he encounters a black taxi driver, named Fekadu, who tells him his story. He is not sure whether or not he should believe it but by the end of their trip together William realizes how much he loves and cares for his
Insect, small, air-breathing animal characterized by a segmented body with three main parts—head, thorax, and abdomen. In their adult forms, insects typically have three pairs of legs, one pair of antennae, and in most instances, two pairs of wings. Insects rank among the most successful animals on Earth. About one million species of insects have been identified so far, which is about half of all the animals known to science. That is why for every pound of human on the earth there are 10 pounds of insects. So that is why there are many reasons why insects are so successful, their exoskeleton, their size, their body function, the way they reproduce, and their development of metamorphosis.
Neck and beak – *The neck is long and felixble as a result bird is able to rotate its head for reaching food and can see all around. *The jaws are teethless and are produced into beak which are variously modified to pick up food, making nests and preening etc. Skin – *The skin of bird is loose which allows movement of the flight muscles. Limbs –*Forelimbs are modified into wings and are attached closer to center of gravity and farther from head than in other animals. *The wings act as propelling organs for flight. *Hand bones are small, fused, flattened and specialized to manipulate the flight
