... of males who smoke decreased from more than 60 percent to about 25 percent; however, the percentage of women who smoke cigarettes increased. Smoking also became more prevalent among young adults, with about 29 percent of high school seniors admitting to smoking in 1975; but by 1987 this proportion decreased to 18.7 percent. There are programs that exist to help smokers quit. Some involve group support, whereas others use aversive techniques in which participants smoke many cigarettes rapidly to the point of becoming sick of them. More than 30 million persons in the U.S. say that they would like to quit smoking but c ...

... abortion. Many people approve of abortion because they consider that a fetus is not an individual human until birth. Abortion is wrong and it shouldn't be legal. If a doctor killed a baby one minute after it were born, they would be charged with murder. But if they were to kill a baby one minute before it were born, and a minute before that and so on, they would not be considered a murderer. At what minute can one consider life worthless and the next precious? Some people will say that abortion is not a matter of life and death, but medical research proves that the fetus is a living organism. People also a ...

... discussing the protein defect in the CF gene, the bio-chemical defect associated with CF, and possible treatments of the disease. Finding the Cystic Fibrosis Gene: The classical genetic approach to finding the gene that is responsible for causing a genetic disease has been to first characterize the bio-chemical defect within the gene, then to identify the mutated protein in the gene of interest, and finally to locate the actual gene. However, this classical approach proved to be impractical when searching for the CF gene. To find the gene responsible for CF, the principle of "reverse genetics" was appl ...

... long been a fascination with the human race. The ancient Aztec cultures used to perform a type of brain surgery on humans. This is evident from the human remains that we find with incisions and piece's missing of the skull. Whether or not these primitive surgeries were successful is unknown. The earliest way for man to observe the brain was by noticing brain damage to a particular area of the brain that was damaged. Such observations were first recorded some 5,000 years ago (Myers,1995). The most popular case is that of Phineas Gage a railroad worker that had severe frontal lobe damage. This happened when a ...

... of her doctor. She suffered from a terminal illness called ALS (a.k.a. amyotrophic lateral sclerosis or Lou Gehrig's disease). The disease progressively worsens until it robs the individual of all their abilities (like walking, control of body movement, swallowing and breathing) until they are totally dependent on mechanical devices to survive. Before she ended her life, she brought the debate over assisted suicide and the right to die to the Supreme Court of British Columbia (which was denied) and then to the British Columbia Court of Appeal which was lost. She fought though for the right to change the l ...

... one to five. Level 5 having the most lethal virus. Why would I want to be a virologist? Well the reason for me is, I find viruses fascinating. Trying to find cures for diseases like HIV and the common cold. Yes, the common cold is caused by a virus. And there is no cure for the common cold, just vaccines. I don't know, and could not find that much information on exactly how virologists find cures and vaccines. But I know that they need antibodies to make these cures. And there are two primary ways of making these antibodies. One, they can take them from patient zero. Patient zero would be wher ...

... affecting the entire mind and body, causing a person to feel miserable in many ways. Changes in brain chemistry make it happen. It is a brain disease. We do not know what causes depression . We used to think it was due to something unhappy in a person's life or to some psychological hang-up. We now know, however, that this disease happens to people who have no reason "to be depressed." In other words, depression can strike normal and healthy people. A depressed person will feel very tired all the time, even when they have not worked or exerted themselves very much. They will be just as tired on days when they have r ...

... understood to be a complex combination of one or more factors, such as psychological and physiological factors as well as chemical interference (such as alcohol and drug abuse). The source of the behavior varies according to age with the younger sufferers having more physiological problems which they grow out of, while with older people, stress and substance abuse play a larger role. is most common among children from the ages of 4 to 12. Estimates for the percentage of the population which will sleepwalk at least once in their lifetime range quite a bit. Some sources say that most children will walk in their slee ...

... is not legal for medical or personal use in the U.S. It is the biggest debated issue of drug legalization today. Marijuana is a natural drug that is a product of the hemp plant. The leaves and flowering top of this plant are usually dried and then smoked or eaten. It causes a state of relaxation and does not produce hyperactivity or impair vision like other drugs, such as, cocaine or methanfedamines. Marijuana as opposed to cocaine and methanfedamines is not addictive. Cocaine and methanfedamines are however legal for specific medical uses. When marijuana is mentioned in emergency room episodes, it is only in ...

... the virus. AIDS is transmitted this way by way of the semen. This is also the way most people get AIDS. (Madaras,187) The second most common way people get AIDS is by dirty intravenous needles. It is transmitted by the blood or other body fluids on the needle, and when someone else then uses the same needle, they have a high risk of catching the virus. The third most common way AIDS is spread is by blood transfusions. This is done almost the same way as by IV needle but it is always by the blood.(Madaras,187) The most rare way the AIDS virus is spread is by a mother passing it to fetus inside her.(Madaras,18 ...
