... over chemical agents at times because of the fact they have the potentials to mutate, reproduce, multiply and spread over an extensive geographical territory through wind, animal and insect transmission. Also, unlike chemical weapons, due to its’ lively state biological agents tend to find niches, and continue to grow exponentially without termination. Because it hardly reaches a closure, biological weapons are not widely used. Nevertheless, history states it has been used during World Wars (I & II), cold war, and last but not least, also very recently in Tokyo, Japan by terrorists. Using such lethal weaponry kill people in exceptional amounts. Furthermore, ...
... the latter crises and their potential to influence the health of an elderly individual, I expect to learn of means by which the elderly may give way to in order not to become overwhelmed with the changes. . In many cases, however, it may be possible to anticipate crises and prepare for them. It may also be useful to recognize the impact of crises that have occurred so that one can take account of them appropriately. Holmes and Rahe with the Social Readjustment Scale have done some very interesting work in this area. This allocates a number of “Life Crisis Units” to different events, so that one can evaluate them and take action accordingly (Niven 99). ...
... scientists of his day, was so entranced by the excitement of synthesizing his product and achieving his goal that he did not stop to think of the ramifications of his accomplishment. The ethical dilemma was not explored before hand, and this to me is the great tragedy of most scientific discovery, since I firmly believe each scientist is responsible for that which he creates. Djerassi does confront a few questions of ethics and morality after the fact. On page 61, in chapter 6, he reflects on the argument of the use of poor Mexican and Puertorrican women for preliminary experiments. Is this just another manifestation of exploitation of the poor? Djerassi says absolu ...
... 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 applied. Scientists accomplished this by linking the disease to a specific chromosome. After this linkage, they isolated the gene of interest on the chromosome and then tested its product. Before the disease could be linked to a specific chromosome, a marker needed to be found that would always travel with the ...
... Cystic fibrosis is the most common inherited fatal disease of Caucasians, occurring about once in every 2500 births. If both parents carry the gene responsible for the disease, they have a one-in-four chance of having an affected child. In 1989, the gene responsible for cystic fibrosis was identified on chromosome 7 (out of 23 chromosomes). Since that time more than 200 different mutations in the cystic fibrosis gene have been described, and tests have been developed to detect the most common alterations. These tests can identify unaffected carriers of the disorder. Sickle-Cell Anemia Sickle-Cell Anemia, also called sickle-cell disease, is a hereditary condition w ...
... it. Dyslexia is not the result of low intelligence. The problem is not behavioral, psychological, motivational, or social. It is not a problem of vision; people with dyslexia do not “see backward.” Dyslexia results from the differences in the structure and function of the brain. People with dyslexia are unique; each having individual strengths and weaknesses. Many dyslexics are creative and have unusual talent in areas such as art, athletics, architecture, graphics, electronics, mechanics, drama, music, or engineering. Dyslexics often show special talent in areas that require visual, spatial, and motor skills. Their problems in language processing dis ...
... repeated attacks. Except for lotions to relieve pain, itching, or inflammation, no established treatmemt has actually been developed. The second type of the herpes simplex virus, however, is the usual cause of genital herpes. Herpes infections of the genital area have become increasingly common, going along with a rise in general of many sexually transmitted diseases. Sometimes accompanied by headache and fever, the condition usually begins with a mild itching, followed by the development of clusters of blisters that break and crust to form scabs that eventually dry up. The process may last one to three weeks. In many cases new clusters of blisters appear as oth ...
... was an amine (a type of Nitrogen-containing compound), so Funk proposed that it be named vitamine, from vital amine. It was later discovered that different vitamins have different chemical properties. This discovery caused vitamine to be turned into vitamin. In 1912 Hopkins and Funk made a hypothesis. The hypothesis stated the absence of some vitamins could cause diseases such as beriberi and scurvy. Later a letter was assigned to each vitamin. The letters which were assigned to vitamins in the early years of vitamin research categorize them according to their functions. As research progressed, the vitamins were given scientific names. Fo ...
... are illegal to use if not prescribed by a physician, and have been banned by nearly all athletic organizations, both professional and amateur. When you think of someone who uses steroids you typically picture someone who is massive, and whose muscle mass is very well defined. A picture comes to mind of the giant body builder, who is so big he can't touch his back because his biceps are in the way, but he can manage to bench press his car. The possible growth and development is amazing. With much less work necessary, the results can be astounding. Athletes can get bigger, stronger and faster, with less effort than previous. The limits of an athletes potential ...
... subway system on March 20, 1995. The five packages were disguised to look like lunch boxes or soda conta iners and it was reported that the chemical agent used was an impure or dilute solution of sarin, a nerve agent developed by Nazi Germany during the '30's. This was the beginning of a frightening future for the modern world. "Organized and indiscriminat e murder" (Tokyo, A1) on a large scale is clearly possible and chemical weapons are likely to be a terrorist's vehicle for mass destruction. The threat of terrorist use of chemical weapons is now quickly forcing its way into the thoughts of people all around the world. The attack in Japan, "says Israeli terrori ...
