  • Aids As An Invader - 1,827 words
    Aids As An Invader Acquired immune deficiency syndrome, also known as AIDS, is a silent invader. The first cases of this disease were reported in the early 1980s. AIDS is caused by the infection known as human immunodeficiency virus (HIV), which is a microscopic organism that can grow and multiply inside living cells. HIV attacks and disables the bodys immune system. The immune system is the system that usually fights off illnesses. When the immune system breaks down, a person with AIDS will develop life-threatening illnesses. (Flynn & Lound, 6) The invasion of the AIDS virus in an individuals body leaves the body open to an invasion by many other different infections, called opportunistic d ...

    An Uphill Climb From the viewpoint of Sharon My husband? Yeah, he was a great guy. I havent seen him in a long time. I guess thats because, well, heaven and earth are so far apart. I always knew he loved me. He never let me forget it either. I remember the first time we met. It was in high school, I was about 14 years old, and he was a senior. I was practicing with the cheerleading squad after school when I saw him. He jumped from a window about five feet above the ground. I think he did it to impress me but Im not sure. He started to come over to talk to me and he was really sweet. I could tell that he didnt have a lot of the money that the other kids had. Later in the day my boyfriend beat ...

  • Anesthetics - 1,530 words
    Anesthetics Anesthesia is a partial or complete loss of sensation or feeling induced by the administration of various substances. For many decade, people have used one form of an anesthetic during surgical procedures. Some people also use some of these anesthetics as recreational drugs, e.g. laughing gas (a.k.a. Nitrous Oxide). The term anesthetic literally means "without feeling". There are many different types of anesthesia, but they are usually put into three groups. These groups are gene- ral anesthetics, local anesthetics, and spinal anesthetics. A general anesthetic causes a complete loss of consciousness. They are used when having a serious operation or in the case of an emergency ope ...

  • Animal Experimentation - 1,936 words
    ... and adults. The only reason man is able to perform these vital operations is because dogs, who are the closest model to humans for this type of procedure at this time, were used for experimentation. By using the canines for experimentation, they have been able to perfect heart surgery in humans (Wil 65). Another benefit humans have had because of animal experimentation is the treatment of familial hypercholestolemia. It was discovered that Watanabe rabbits have a genetic disorder in which they have dangerously high cholesterol levels. A doctor found this problem on the rabbits' feet, which had yellow "pockets" full of liquid. He soon found out this disorder was similar to the ones in hu ...

  • Animal Rights - 488 words
    Animal Rights Animal Rights As Doctor Zola-Morgan stated in a speech to animal right activists, I've seen the impact of the animal rights movement. I believe this is an attack on science of the worst kind. If we allow it to prevail it will take us back to the dark ages. Too much of the public has come to think of medical researchers as tormenters rather than healers. The good is overlooked and the bad is exploited. Although many people think that animal research is morally wrong, animal research should continue because it is critical to continued progress in human health and alternatives to research animals are not available. Animal rights activists feel that animal research is immoral. They ...

  • Animal Rights Vs Human Rights - 1,858 words
    Animal Rights Vs. Human Rights h Laboratory animals The use of laboratory animals is important to three main areas: biomedical research, product safety testing, and education. Biomedical researchers use animals to extend their understanding of the workings of the body and the processes of disease and health, and to develop new vaccines and treatments for various diseases. The research these people do isnt only for human benefit; it is also helping to develop veterinary techniques. The industry uses animals to test the effectiveness and safety of many consumer products, such as cosmetics, household cleaning products, pesticides, chemicals, and drugs. Educators, from elementary school all the ...

  • Animal Testing - 953 words
    Animal Testing For centuries, animals have been used in medical research. Since 1875, animal experimentation has been an on going heated debate on whether experiments on animals are ethical. At the very start, the movement against animal testing focused mainly on the "inhumanity of hurting and killing living beings for experimental discovery" (Achor 95). However, in these few decades, scientific invalidity was one of the focusing claims to object to vivisection, which is an "injurious use of animals in laboratories and classrooms, whether for experimentation, product testing, training, or demonstration" (Achor 94-95). Animals are innocent and they are not able to fight back for any means of ...

  • Cardiac Rehabilitation - 272 words
    Cardiac Rehabilitation Despite major advances in cardiopulmonary bypass technology, surgical techniques, and anesthesia management, central nervous system complications remain a common problem after cardiopulmonary bypass. There are several potential causes of brain damage during open-heart surgery, including prolonged or severe arterial hypotension, as well as emboli emanating from the cardiopulmonary bypass circuit or the operative field(Benedict RH, 1994, Newman 1995). In the coronary artery bypass population, advanced age (* or = 75 years) is associated with an 8.9% neurologic deficit rate. Mortality is increased ninefold in the elderly patient with a neurologic deficit. Cerebral complic ...

  • Cloning - 659 words
    Cloning Nicole Pluta November 29, 1998 Scientific experimentation has led us to many great discoveries such as: Chemotherapy, heart surgery, and bone marrow transplants. Recently scientists have discovered a new way to heal humans. This is known as cloning. Although they have yet to clone a human they have cloned sheep. Cloning has brought up a huge controversy among the American people. There are two sides to the story. Either you agree with cloning or you dont. The only way to help make that decision is to look at the good and bad points of cloning. There are many positive aspects of human and non-human cloning. Human cloning technology could be used to reverse the number one killer in the ...

  • Cloning Sheeps - 541 words
    Cloning Sheeps Three years ago a sheep named Dolly became the biggest news since the first successful open-heart surgery. Dolly, unlike every other mammal on earth is an identical copy of its mother. Dolly has no father. The "miracle" of cloning was preformed by Dr. Ian Willmut and his team at Roslin Institute in Edinburgh, Scotland. The new research has opened a large amount of possibilities for the future use of the technique as well as many ethical issues regarding human cloning. The Roslin Institute team created Dolly by transferring the nuclei of adult sheep cells in to the egg of another female sheep. The egg had its natural nucleus removed by microsurgery. Ones the new nucleus was imp ...

  • Mary Jo Bang - 595 words
    Mary Jo Bang Bill Mueller April 18, 1999 English 1-2 Prof. McMullen Mary Jo Bang : Apology for Want Quiet, unassuming, serene. These characteristics define the appearance of poet Mary Jo Bang. There is, however, another side to the humble St. Louis native which is not readily apparent by either her looks or her demeanor. Beneath her deceiving facade lies another person entirely, which only emerges through her poetic talents. Although she also read from her new manuscript which has not yet gone to print, Mary Jo Bang primarily read from her collection which won the Katherine Bakeless Nason poetry prize in 1996, entitled Apology for Want. According to Edward Hirsch Apology for Want is, a...dar ...

    ... would be too troublesome and economically unjustifiable.  Firms would not recognize the need to automate unless their competition did. They were not even getting any good publicity from their successful installations, since General Motors was down playing everything because it feared labor opposition. Something had to be done, and soon before the company was forced to fold. Engelberger commissioned a consulting firm to determine a way to promote the UNIMATE. The solution was actually quite simple; it was a matter of economics. The robot was priced to high; it was cheaper to hire more employees than it was to automate. When the price was reduced, sales jumped six fold. Which puts ...

  • Running - 512 words
    Running In this study, I investigate the affects that running has on reducing the risk of some health problems. I am doing this because I run about 40 to 60 miles per week, and my family has a history of health problems. For instance, my grandfather suffered a heart attack, and he also had cancer when he was about the age of 50. Furthermore, my grandfather, on my dads side of the family, has also had triple bi-pass heart surgery from a heart attack he has had recently. Here, I present information from some sources that talk about the affects that running has on reducing health risks. My sources agree that running, and some other aerobic exercises, reduce the risk of: Diabetes, diverticular d ...

  • Trade In Ancient Greece - 2,695 words
    Trade In Ancient Greece When we discuss the economics of the ancient world, we must be careful not to use the formal Economics which we employ in analyzing our own society, since Economics is a function of the way a society runs, not the set of rules under which a given society operates. We cannot remove ourselves from awareness of the economic disciplines which our schools teach, and even if we formally try to suspend Economics as a framework, we retain the image of the economic framework in our language and our general pool of ideas. Yet some distancing of ourselves from modern economic theory is necessary in starting an investigation of a foreign world, in order to let the economic operat ...
