Rabbit Genetics :: essays research papers

Rabbit Genetics The similarity between the physiology of rabbits and humans makes the rabbit a good model for research into human disease. The most prevalent types of rabbits are cottontails and European rabbits. Domestic rabbits are tame assortments of European rabbits. The Californian, Florida White, and New Zealand White are the most common breeds used in research. Until 1912 rabbits were classified as rodents. Scientists discovered that the two types of animals differed in several distinct anatomical ways. Rabbits, for instance, have a second pair of upper incisors, known as "peg teeth," that are found behind the two main visible incisors in the upper jaw. Rabbits have elongated hind legs adapted for moving at high speeds over open areas. Rabbits generally move in a hopping motion. They also have webbed toes to keep them from spreading as they hop. Rabbits have flexible necks, which allow them to turn their heads more than rodents. Their spines are long and fragile and susceptible to fractures if the animal is held improperly. Research The ability to produce tumors in rabbits makes them useful models to study chemo/immunotherapy, as well as immunoprevention of certain cancers. Cholesterol studies: Rabbits have been used to test Probucol, a drug that lowers blood cholesterol and retards the development of hardening of the arteries. Eye ear and skin studies: Rabbits are used to study middle and inner ear infections, which affect millions of infants and children each year. †¢ Rabbits are also used to study Entropion, a condition in which the eyelashes are turned inward, as well as Glaucoma, which often results in blindness. †¢ Rabbits are used in eye and skin irritation tests to develop appropriate procedures for handling certain chemicals and to predict the toxicity of accidental exposure. †¢ More than 10,000 blind or visually impaired people have benefited from corneal transplants, possible only because of hundreds of trials on rabbits. Drug metabolism: Rabbits have been used to study the effects of marijuana on the central nervous system. Pregnacy Test Presently a woman who wants to find out if she's pregnant need only make a quick trip to the local drug, grocery, or convenience store; purchase an over-the-counter home pregnancy test kit; perform a simple test; and she'll know the results within a matter of minutes. Not so long ago, however, it was not nearly as quick or easy: Awomawho thought she might be with child had to schedule an appointment with her doctor, make a trip to his office, give a urine sample, go home, then spend an anxious couple of days waiting for the office to telephone with the test results.

Alahmad and Murphy on Business Ethics Essay - 981 Words

The first two journal articles that were compared and contrasted were Ala Alahmad’s 2010 article on To Be Ethical or Not to Be: An International Code of Ethics for Leadership and Patrick Murphy’s 2009 article on The Relevance of Responsibility to Ethical Business Decisions. Some key findings of Alahmad’s writings were that ethics and leadership were closely tied together; they were found to be derivatives of one another. He mentioned that ethics is an individual thought process of making good or poor decisions. Alahmad described an international code of leadership that was heavily veiled with great moral fibers. Some notable characters of his code included honesty, respect, punctuality, humbleness, and great dignity. However, in†¦show more content†¦Finally, in comparison Murphy elicits empirical researchers to explore, examine, and refine his findings. In essence, he did not perform an extensive review of his results similar to Alahmad’s re sults. Alahmad and Murphy both shared similar ideas about the moral compasses be pointed in the right direction as it relates to ethics. Rather if it was a code for international ethics or an examination on responsible both cases proved to be win-wins for ethics. There were no major points of contrast that were note worthy. On some level, both writers were going for the same goal just in different way. The next two articles that were compared and contrasted were Peter Drucker’s 1981 article on What Is Business Ethics? and Milton Friedman’s 1970 article on The Social Responsibility of Business Is To Increase Its Profits. Drucker linked business ethics as a monitoring tool that called out businesses who received special ethical treatments. He noted that what we refer to as ethics should be called ethical chic. This turned out to be highly debated statement of that period. Drucker’s statement did not seem to be related to the core principles of what ethics was established for. Drucker’s main claim was that business ethics elevates businesses to a higher level than that of regular citizens.
