.... this disease. It is "the common cold of mental-health problems", striking the rich and the poor as well as the young and the old (Rosenfeld, 1999). Experts think a genetic vulnerability combined with environmental factors may activate an imbalance in brain chemicals called neurotransmitters (Mental Health). seems to run in families and can be brought on by stress or physical illness. Having a family history of increases your risk of developing the condition. Researchers have identified several genes involved in bipolar . But not everybody with a family history of will develop the disorder. Your genes may have predisposed you to be at a certain point on the ha ....

.... by tobacco growers by imposing heavy tariffs on their tobacco crops. Tobacco use was very well established by this time however, so the taxes didn’t slow production or demand. Many countries at this time had prohibited or restricted use of tobacco. Harsh punishments for smoking tobacco were enacted in Russia, Turkey, and other countries, especially China where tobacco sellers were decapitated. Cigarette smoking did not become popular until the late eighteen hundreds. Although the U.S. was not the first country to use cigarettes, in eighteen eighty three American James Bonsack developed a cigarette rolling machine. Where a skilled cigarette roller could roll about four hu ....

.... of helping a single person or even saving a person’s life. A career in the medical field is an exceptional choice for an intelligent person who has ambition to help people in need, has the hungry for knowledge, and is motivated to work to the best of his ability. Hippocrates is the father of modern medicine (1). He probably was one of the best known physicians who really gave a basis for medicine. His enthusiasm in medicine helped him in his quest to help humanity. Hippocrates developed a set of medical ethics that influences medical practice still to this day (Hopke 494). Physicians that are starting to practice medicine generally take the Hippocratic Oath, which Hippoc ....

.... However, several investigators dispute the idea of a special type of inherited alcoholism affecting only such groups. Even for these populations, balanced genetic models leave room for the substantial impact of environmental, social and individual factors so that drinking to excess can only be predicted within a complex, multivariate framework. The denial of this complexity in some quarters obscure what has been discovered through genetically oriented research and has dangerous consequences for prevention and treatment policies. A tremendous amount of attention and research has recently been concentrated on the inheritance of alcoholism and on the poss ....

.... In the case of a.d.d. they give proper messages or do not at all in times, it all differs at times and when this happens it causes a.d.d. to occur. There are a few different categories that a.d.d. can be broken down into one of them is A.D.H.D. which makes it very difficult for children to follow along in class. Usually children with A.D.H.D. are more problematic or harder to keep in line, because A.D.H..D. is involving much more hyperactive behavior. A.D.D. is a genetic disease, and in the case of A..D..D. If a child has it there is a more than good chance the parent has it as well. Fifty percent of parents that have kids with A.D.D. have A.D.D. as well. There are m ....

.... been inoculated, the virus enters small nerve ends around the site of the bite, and slowly travels up the nerve to reach the central nervous system (CNS) where it reproduces itself, and will then travel down nerves to the salivary glands and replicate further. The time it takes to do this depends on the length of the nerve it must travel - a bite on the foot will have a much lengthier incubation period than a facial bite would. This period may last from two weeks to six months, and often the original wound will have healed and been forgotten by the time symptoms begin to occur. Symptoms in humans present themselves in one of two forms: ‘furious rabies', or ‘ dumb rabi ....

.... to achieve brought about the invention of the artificial heart. The potential for such inventions are enormous. According to the American Heart Association, there are between 16,000 and 40,000 possible recipients of artificial heart devices under the age of sixty-five. If perfected, it would enable us to save thousands of human lives. In considering the full impact of artificial heart devices on society, we must not narrow our thinking to include only the beneficial possibilities. There exist moral, ethical, and economic factors that accompany these new innovations to humanity. Who will receive these brilliant inventions? Obviously not all of the patients will get tr ....

.... It can occur any time in the year. affects the fluid lining of the brain. In the blood the virus can be fought off by white blood cells, but in the spinal fluid there is no white blood cells so it cant be fought off. Once the infection starts, it can spread very quickly thought the body. can cause a lot of brain damage in a little while, and can kill in 24 hours. The disease is often followed by a variety of after-effects, some permenant and physically disabling and some less obvious, affecting the patient emotionally. Although many people will make a quick and complete recovery others will need a lot of support and care over the weeks and months following there ....
