.... other organs, contain an inner core with high pressure zones that compress and collapse blood vessels, often 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. Malignant tumours are diagnosed by examination of their vascularity, shapes, forms of cells division, and differentiation. More than a hundred different types have been identified in humans. In general, those derived from epithelial tissue are carcinomas, and those from connective tissue ar .....

.... normal cells undergo physical and structural changes as they develop to form different tissues of the body. Differentiated cells specialize in multiple physiological functions. For example, a highly differentiated cell like a nerve cell still shares many features in common with all cells (i.e. nucleus, cell membrane, and mitochondria). However, microscopically and functionally it is unique from other cell types in the body and performs certain functions specific to that cell. Benign are usually associated with a more favorable outcome, unless their presence causes pressure in critical areas such as the brain. The degree of diff .....

.... were caused by a demon who took possession of the victim’s body. The early civilizations would treat the mental illnesses by trying to make the body so uncomfortable that the demon would want to leave. But, by the late eighteenth century, most people were convinced that mental disturbances were not caused by supernatural powers. Scientists, however, were still unsure whether such illnesses stemmed from physical problems or psychological abnormalities. The nineteenth century saw an explosion of interest in medical theories regarding mental disorders. In 1861, Paul Pierre Broca discovered that tumors led to speech loss, and sp .....

.... to warn their customers, except if a new ingredient is added, in which case they should be notified. No one is saying get rid of the Surgeon General warnings, but enough is enough! If a person wants to smoke 3 packs of a day, then that is their choice; tobacco companies should not be held responsible. Let us examine the hype surrounding the supposed danger and addition of nicotine. The Food and Drug Administration tells us that nicotine (the addictive drug found in ) is just as addictive as cocaine and should be illegal. "Much of the rhetoric of the anti-smoking movement seeks to demonize tobacco smokers as "nicotine addicts". In .....

.... polls before the vote revealed strong support for it,the ballot was defeated by fifty-four to forty-six percent,and euthanasia remains illegal in Noth America. In addition to violating civil law,euthanasia also contradicts the laws of many religions of the world. It is God who controlls life and death. Man will take this responsibility if euthanasia is permitted. It is stated in the ten commandments,"Do not commit murder". Murder can take many forms,one of which is suicide,the taking of one's own life. This is forbidden by the Christian religion. There is a picture on my grand-mothers wall which stated that"human life is no .....

.... it has also been transmitted by the reuse of needles because the health care systems are so under financed. Ebola wasn't thought to be an airborne virus, but recent studies by the US Army Medical Research Institute of Infectious Diseases and the CDC found that monkeys showed Ebola like symptoms after being exposed to aerosolized Ebola. The studies also found that the virus is many times present in the respiratory systems of Ebola victims. Although the 1989 outbreak in Reston, Virginia wasn't harmful to humans, it was found that droplet and vomit transmission played a major role in spreading the disease through the quarantine .....

.... amplification or mutation, aberrant tumor suppressor expression or mutation. Also, subversion of host antitumor immune responses may play a role in the pathogenesis of cancer (Sharp, 77). Ovarian clear cell adenocarcinoma was first described by Peham in 1899 as "hypernephroma of the ovary" because of its resemblance to renal cell carcinoma. By 1939, Schiller noted a histologic similarity to mesonephric tubules and classified these tumors as "mesonephromas." In 1944, Saphir and Lackner described two cases of "hypernephroid carcinoma of the ovary" and proposed "clear cell" adenocarcinoma as an alternative term. Cle .....

.... are not. Fit people also tend to live a longer life. Doing aerobic and weight exercises such as running, walking, swimming, weight lifting etc. and a healthy diet is important in preventing or treating the above diseases or conditions. When you are fit, you feel energized and want to be active. Unfit people are always sitting around saying they are tire and don't want to do things. The truth is, unfit people are always tire. Their heart and metabolism rate are low, so when they want to do something, they do not have enough energy to do it. But when you feel energized, you perform task better, whether in school or at work. .....

.... used, in this case, by a HIV positive person.) The criminalization of intentionally spreading AIDS has been a big issue recently, and still remains so. As of September, 1991, legislation criminalizing AIDS transmission has been passed in 24 states. Among these states are California, Idaho, Ohio, Missouri, Michigan, and South Carolina. Under these current laws, it is a crime to knowingly transmit the virus through sex, sharing needles, donating infected blood, organs, or skin tissue. The first person to go to court under these laws in Michigan was Jeffrey Hanlon. Hanlon was a gay man who infected another man from .....

.... although the mild carcinogenic has been deemed safe for human consumption, several studies have linked the chemical to bladder cancer. If the chemical were truly safe, it would not require a warning label on products that contain it. Despite the fact that the United States government has deemed saccharin safe, in actuality, it should be banned until its effects on the human body are completely understood. Saccharin is an organic petroleum-based compound that is three to five hundred times sweeter than sucrose. It is non-nutritive because the human body is unable to metabolize the foreign chemical. Saccharin does not contribute ca .....
