... of Alzheimer's disease are rather easy to distinguish and classify. Patients of the disease lose much of the information that they have recently learned and cannot learn anything new. They begin to constantly misplace objects, often repeat themselves, and usually become confused in simple situations. When in relatively simplex places patients may become lost or even forget where they are. Psychologically however, patients begin to become depressed most of the time and be anxious or confused. Some become restless and can barely ever sleep. The cause of the disease, although not completely proven, is strictly genetics. It is passed down from generation to genera ...
... programs to gain weight. However this kind of desired weight is not measured in fat but in muscle mass. Many muscle and fitness magazines will feature advertisements and articles for such gains in body mass. Advertisements for diets can sometimes be very dangerous though. Pretty well all the people used in these particular ads are slim and beautiful and it can therefor be very misinterpreting to someone who is overweight. The pressure of being fit can lead to very damaging disorders such as anorexia and bulimia. These two very serious conditions affect a very large amount of women and men in North America these days and can be quite lethal if not cured. S ...

Of course everybody wants better biceps and triceps but when using steroids to achieve this goal there is a large price to pay. However, stero ...
... Vegas has the highest per-capita suicide rate in the country. This coincides with its enormous expansion, yet the most talked-about suicides -- those of tourists leaping from hotel balconies after losing everything they had -- are dangerous myths for a city poised to become America's newest economic icon. In fact, tourists taking their own lives surrounded by the glamour of the Strip comprise only a small percentage of the fatalities. The bulk are those who moved here for jobs, who live just beyond the lights. Eight times as many residents kill themselves here as do visitors. Second, I am told that in Las Vegas I will feel more alive. Anything can be had here; this ...
... serious thought for about a year, and then one day she actually attempted to kill herself. I thought if someone wanted to kill themselves it would be hard to fail. That's when I figured she didn't really want to die. It was a cry for help, and she didn't know of any other way to ask for it. I stayed a week with her through this trying period in her life, and found out it was partly because of her French exchange student boyfriend. They weren't broken up, but he had to go back to France, and she couldn't see him as much as she would have liked to. Her mother started taking her to a psychiatrist to help her through her depression. If we hadn't have done this she migh ...
... must first ascertain what HIV is, how the body attempts to counter the effects of viruses in general, and how HIV infects the body. Definition HIV is the virus that causes AIDS. HIV is classified as a RNA Retrovirus. A retrovirus uses RNA templates to produce DNA. For example, within the core of HIV is a double molecule of ribonucleic acid, RNA. When the virus invades a cell, this genetic material is replicated in the form of DNA . But, in order to do so, HIV must first be able to produce a particular enzyme that can construct a DNA molecule using an RNA template. This enzyme, called RNA-directed DNA polymerase, is also referred to as reverse ...
... mucous glands. Its epithelial cells release large amounts of glycogen, which is anaerobically metabolized to lactic acid by resident bacteria. Consequently, the pH of a woman’s vagina is normally quite acidic. This acidity helps keep the vagina healthy & free of infection, but it is also hostile to sperm. Although vaginal fluid of adult woman is acidic, it tends to be alkaline in adolescents, predisposing sexually active teenagers to sexually transmitted diseases. In virgins, the mucosa near the distal vaginal orifice forms an incomplete partition called the hymen. The hymen is very vascular & tends to bleed when it is ruptured during the first coitu ...

... importance to educate people about AIDS and to promote safer sex. The key word now is prevention. Among many proposed policies to help prevent AIDS infection, one of the most controversial is mandatory AIDS testing. Mandatory AIDS testing is theoretically very effective, however, when it is applied, it is not practical at all because one is dealing with human nature, the odd nature of the virus itself, and also all of the stigmas that are attached to AIDS. Therefore, not only will mandatory AIDS testing not prevent HIV infection, it will indirectly increase HIV infection because of the adverse effect it will have on voluntary testers. One of the major flaws ...
