.... to encourage individuality in, and a healthy relationship between, each twin from birth so that they will not experience individualisation problems (Siemon, 1980). According to Sandbank (1988), three main factors play roles in the development of twin individuality. These are: competition in the twinship, the school environment and parental attitude. Competition, according to Mathias (1992), results from being either envious or jealous of someone else. Jealousy is something that twins probably experience before other children as they are always competing for a share of parental attention. So, identical twins will adopt different strate .....

.... included activists, physicians and HIV positive women who used the meeting as a forum to voice their concerns about how best to balance women's own medical needs with those of their infants. Other concerns of activists that were voiced were that they don't want laws, policies or medical care imposed on women merely as "vectors" who may transmit HIV to their infants. The new guidelines recommend that all pregnant women should receive HIV counseling and testing. These guidelines are aimed at helping pregnant women know their HIV status early so that medical care, including zidovudine (Retrovir, known as AZT, Burroughs Welcome Co., .....

.... I may soon lose others. My own sexual behavior and that of many of my friends has been profoundly altered by it. In U.S.A. one man in10 may already be carrying the AIDS virus. While the figures may currently be less in much of the rest of the country, this is changing rapidly. There currently is neither a cure, nor even an effective treatment, and no vaccine either. But there are things that have been PROVEN immensely effective in slowing the spread of this hideously lethal disease. AIDS stands for Acquired Immune Defficiency Disease. It is caused by a virus. The disease originated somewhere in Africa about 20 years .....

.... of people who do not consume animal flesh, was not used until around the mid-1800s. The concept of vegetarianism, however, dates back much further. The Greek philosopher Pythagoras, considered by many to be the father of vegetarianism, encouraged a non-meat diet among his followers as a diet that was the most natural and healthful (Messina 3). A excludes the consumption of meat, and can be exercised by people for a number of reasons. The largest majority of individuals chose vegetarianism for health related reasons. For example, someone with an ulcer might be prescribed a strict diet of vegetables in order to promote the healing process. O .....

.... problem, a psychiatric examination can be very helpful. Many of the symptoms of suicidal feelings are similar to those of depression. Parents should be aware of the following signs of adolescents who may try to kill themselves. Child and adolescent psychiatrists recommend that if one or more of these signs occurs, parents need to talk to their child about their concerns and seek professional help when the concerns persist. Teen suicide leaves behind an unceasing wake of questions. Parents, friends, and classmates all ask in endless echo-WHY? Everyone tries to make sense of it. But no sense can be made. All questions. No answers. Just the .....

.... protein it produces, a larger than normal molecule they called huntingtin that was unlike any protein previously identified. The question that they did not know was what either the healthy huntingtin protein or its aberrant form does in a cell. Recently, a team from Johns Hopkins University found a second protein called HAP-1, that attaches to the huntingtin molecule only in the brain. The characteristics of this second protein has an interesting feature- it binds much more tightly to defective huntingtin than to the healthy from, and it appears that this tightly bound complex causes damage to brain cells. Researchers are hoping to find .....

.... the early the depression. Mueller had begun to speculate that the lack of sunlight had contributed to the women’s depression. In order to confirm this he exposed the patient to artificial sunlight. He found that over a period of time the patient had recovered from the depression. Today light therapy is the most commonly used method in treating SAD. The two hormones that are affected by the sunlight, and are thought to be the cause of SAD, are melatonin and serotonin. Both of these chemicals “are influenced by photoperiodism, the earth’s daily dark-light cycle� (Wurtman 1989). Melatonin is the chemical that effects mood and .....

.... died from smoking marijuana. (Medical Marijuana, www.norml.com) Marijuana should be studied more extensively for its medicinal purposes, and should be legally available for doctors to prescribe to their patients, judging by their therapeutic need for it. The oldest known medical use of marijuana dates back to the Emperor Shen-Nung in China in the 28th century BC. He prescribed it for such things as constipation, malaria, and absentmindedness. (Medical Marijuana, www.normal.com) Marijuana was also commonly used medically in, but not restricted to ancient Egypt to treat sore eyes, ancient India as an anesthetic, and ancient Greece to tre .....

.... which play a regulatory role in the production of antibodies in the immune system." In the course of the illness, the number of functional T4- cells is reduced to such an extent that new anti-bodies cannot be produced and the defenseless patient remains exposed to a range of infections that under other circumstances would have been harmless. Most AIDS patients die from opportunistic infections rather than from the AIDS virus itself. The initial infection is characterized by diarrhea, erysipelas and intermittent fever. An apparent recovery follows after 2-3 weeks, and in many cases the patient remains without symptoms and functions norm .....

.... 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,188) AIDS is a very rapidly-spreading disease although it is only spread four ways. Ten years ago only two cases of AIDS were known. Nine years ago only seven cases were known. In 1983 over 3,000 cases were recorded, and by 1 .....
