- 13411: Current Status of Malaria Vaccinology
- ... is now accumulating evidence that CTL may be protective against malaria and that levels of these cells are low in naturally infected people. This evidence suggests that malaria may be an attractive target for a new generation of CTL inducing vaccines. The next candidate vaccine that caught my attention was one which I read about in Vaccine vol 12 1994. This was a study of the safety, immunogenicity and limited efficacy ... they seem to work do not reach a high enough standard. But having said that I hope that a viable vaccine will present itself in the near future (with a little help from the scientific world of course).
- 13412: Clinical Chemistry Tests In Medicine
- ... These monomers readily aggregates into ordered fibrous arrays. Platelets and plasma globulins release a fibrin- stabilizing factor which creates cross-links in the fibrin net to stabilize the clot. The clot binds the wound until new tissue can be built (Garrett, 1995). The alpha-, beta-, and gamma-globulins compose the globulins. Alpha- globulins transport lipids, hormones, and vitamins. Also included is a glycoprotein, ceruloplasmin, which carries copper and haptoglobulins, which bind ... The Merck Veterinary Manual, Seventh Edition. Rahway, N. J.: Merck & Co., 1991.

- 13413: AIDS and HIV
- ... Puerto Rico, and the disease had been recognized in 20 other countries. Recognizing the Extent of Infection The health of the general homosexual populations in the area with the largest number of cases of the new disease was getting looked at a lot closer by researchers. For many years physicians knew that homosexual men who reported large numbers of sexual partners had more episodes of venereal diseases and were at higher ... There are three different geographic patterns of AIDS transmission. The first one is characteristic of industrializing nations with large numbers of reported AIDS cases, such as the United States, Canada, countries in Western Europe, Australia, New Zealand, and parts of Latin America. In these areas most AIDS cases have been attributed to homosexual or bisexual activity and intravenous drug abuse. The second pattern is seen in areas of central, eastern, and ... to uninfected T4 cells, leading to their elimination by the immune system. Other autoimmune mechanisms also may play a roll in T-cell depletion. HIV infection also may directly or indirectly suppress the production of new T4 cells. Direct suppression would occur if HIV damaged T precursor cells in the bone marrow. Indirect suppression would result if HIV interfered with the production of specific growth factors. On the other hand, ...
- 13414: AIDS: Aquired Immune Deficiency Syndrome
- ... disease will be a necessity not a right, and most people are to scared or to embarassed to ask their partner if they are infected. The first case of AIDS was identified in 1979 in New York. Workers in the National Cancer Institute developed tests for AIDS enabeling them to follow the transmission of the disease and to study the origin and it's mechanism. It is thought that AIDS was originated in Africa, because it is know to infect some african monkeys and alot of cases have been reported there. In 1990 the WHO(World Health Orginization) announced that there was 203,599 reported cases of AIDS in 1996 it was in the millions! So this shows how fast this disease spreads and how it affects everyone.
- 13415: Breast Cancer
- ... the limits of time and then we will be able to fully understand cancer and its causes. The Breast Cancer Society of Canada is currently funding a 3D Droppler Color ultrasound and Vascular MRI. This new technique is more acute than mammograms because as well as detecting tumors, it can also characterize them. This allows doctors to know exactly what the type of tumor they are dealing with, helping them to ... this disease more seriously. The people who we look up to have gone through the fight against cancer and survived. One public figure who has gone through the pain of breast cancer is Julia Child, world renowned master chef, who found a lump in her breast in 1968. Back then, Breast Cancer awareness was not widespread. “Breast Cancer was barely mentioned”, says Child, now 86. Two weeks after finding the lump ...
- 13416: Humans Are Curious By Nature
- ... the extinction of the dinosaurs no such accounts exist to be taken into consideration. Thus, the scientists most more or less sit in the dark and try to guess at which shred of evidence or new idea should be pursued. Regardless of the amount of evidence present or means at hand it is clear that human curiosity is independent of realistic chances of success. We are pushed by our need to know regardless of if we ever could. So where does that leave us? Will we ever find out what happened to all these lost chapters of our world's diary? It depends on the archeologists and scholars armed with books and theories, spoons and toothbrushes to go and "dig up" the truth. Works Cited -Gould, Stephen J. "Sex, Drugs, Disasters, and the Extinction ...
- 13417: Two Sides of The Brain

The more we integrate those two sides, the more integrated we become ... thin" into the future. Even more startling is evidence coming to light that we have become a left-brain culture. Your brain's right and left side have distinctly different ways of looking at the world. Your two hemispheres are as different from each other as, oh, Micheal Wilson and Shirley Maclean. The left brain controls the right side of the body (this is reversed in about half of the 15 ... relationships. "The left brain is too slow, but the right can see around corners." Dr. Eisenberg thinks that the preoccupation with the plodding left brain is one reason for the analysis paralysis he sees affecting world leaders. "Good leaders don't lead by reading polls," he says. "They have vision and operate to a certain extent by feel." There are ways of correcting out cultural overbalance. Playing video games, for ...

- Tumours A tumour is a mass of new tissue growth that does not react to normal controls or the organizing influence of other tissues, and it has no useful function in the body. This applies to both types of tumours, malignant and benign ... preventing the penetration of blood-borne cancer treatments. It spreads to distant sites by the breaking off of malignant cells, which move through the blood and lymphatic systems, attach themselves, and begin to grow as new colonies.

Now, more than ever, agriculture is a global business, and the parts of the world that never stopped growing hemp are certain to want to infiltrate our domestic market(4). Upscale automobile manufacturer BMW is incorporating hemp into car doors and dashboards, designer Giorgio Armani is weaving hemp into ...
- 13420: History Of Social Security
- ... provide shelter for those without it. This law laid the foundations of modern day economic security. The ideology of the workers supporting the needy was brought over to America with the immigrants. Many of the new communities developed laws very similar to the English Poor Law of 1601. One of the major drawbacks to the English Poor Law of 1601 and the new laws made by Americans is that the laws discriminated against the poor. By this I mean that there was no set criteria for being poor. All the decisions on whether or not you were considered ... the elderly. One person who recognized the severity of the situation was the Revolutionary War hero Thomas Paine. In 1795 Thomas Paine called for the creation of a “public system of economic security for the new nation”.
