.... Chemokines are proteins or (protein receptors) on the surface of T-cells and microphages, they are used to "talk" to, arouse, and attract cells. There are two variants of chemokines, alpha and beta chemokines. Among these there are many different chemokines from CCR5, CCR3, CXCR4, etc… Now AIDS needs the CD4 molecule and the CCR5 protein to be present on a T-cell to successfully infect the cell. It needs the CD4 molecule to latch on to the cell. Once this is accomplished it needs the CCR5 protein to be able to get inside of the cell in order to infect it. Both of thes .....

.... 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 greatly so that new anti-bodies cannot be produced and the defenceless 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 .....

.... probably was spread especially fast by primarily female prostitutes there. AIDS has already become a crisis of STAGGERING proportions in parts of Africa. In Zaire, it is estimated that over twenty percent of the adults currently carry the virus. That figure is increasing. And what occurred there will, if no cure is found, most likely occur here among heteroosexual folks. AIDS was first seen as a dise.ase of gay males in this country. This was a result of the fact that gay males in this culture in the days before AIDS had an average of 200 to 4 .....

.... out literature and condoms to adults, but are they really going to listen? As a community, we can encourage HIV/AIDS testing, but will it be taken advantage of? Since these are adults being familiarized with HIV/AIDS, how to contract it, the consequences, and the raw statistics, they will probably disregard all of the information. Education on the issue of HIV/AIDS obviously needs to begin at an earlier age. Since this is such a controversial issue, the age at which education should begin is debatable. The children need to be mature enough to handle the concerns and they ne .....

.... of losing their role as a parent and needing to find a new sense of identity without this role. Feelings that come with this part of the crisis include depression, self-doubt, heartache and low spirits. They must also handle any kind of regret or feeling of failure about their time and place as a parent. As a mid-life parent, some people (mostly women) can feel caught in the "sandwich generation". This means they are taking care of not only their children, but often grandparents all the way down to grandchildren. This would be a major stressor and crisis on the mid-life par .....

.... pharmacological response. Amphetamine and methamphetamine was used as a recreational drug, which made the user restless, euphoric and alert. Amylnitrite produced strong rushes of euphoria. The average man could not seem to control his/hers use of the drugs, and as a consequence, all of theese products where put under federal control. They cannot be obtained legally without a prescription from a doctor. People with an insight in chemistry and a lack of morale, startet to produce these compunds for their own financial gains. The really clever chemists avoided doing anything .....

.... dwarfism may vary. Abnormally short height in childhood may be due to the pituitary gland not functioning correctly, resulting in underproduction of growth hormone. This may result from a tumor in the pituitary gland, absence of the pituitary gland, or trauma. Growth retardation may become evident in infancy and persists throughout childhood. Normal puberty may or may not occur depending on the degree of pituitary insufficiency that is present, which is the inability of the pituitary to produce adequate hormone levels other than growth hormone. Physical defects of the f .....

.... can be bacteriostatic (bacteria stopped from multiplying) or bactericidal (bacteria killed). To perform either of these functions, antibiotics must be brought into contact with the bacteria. It is believed that antibiotics interfere with the surface of bacteria cells, causing a change in their ability to reproduce. Testing the action of an antibiotic in the laboratory shows how much exposure to the drug is necessary to halt reproduction or to kill the bacteria. Although a large amount of an antibiotic taken at one time might kill the bacteria causing an illness, such a d .....
