... of Malaria both begins and ends. The parasitic protozoan enters the bloodstream via the bite of an infected female mosquito. During her feeding she transmits a small amount of anticoagulant and haploid sporozoites along with saliva. The sporozoites head directly for the hepatic cells of the liver where they multiply by asexual fission to produce merozoites. These merozoites can now travel one of two paths. They can go to infect more hepatic liver cells or they can attach to and penetrate erytherocytes. When inside the erythrocytes the plasmodium enlarges into uninucleated cells called trophozites The nucleus of this newly formed cell then divides asexually to pr ...
... incurably ill persons ask their physician, friend or relative , to put them to death. The patients or their relatives may ask a doctor to withhold treatment and let them die. Many critics of the medical profession contend that too often doctors play god on operating tables and in recovery rooms. They argue that no doctor should be allowed to decide who lives and who dies. The issue of is having a tremendous impact on medicine in the United States today. It was only in the nineteenth century that the word came to be used in the sense of speeding up the process of dying and the destruction of so-called useless lives. Today it is defined as the deliberate endi ...
... to be due to heredity, but such factors as the mother's nourishment while she carried the child before birth may be important. An obvious biological difference exists between boys and girls. Later, as children grow and develop, sex differences become stronger. Certain glands called endocrine have different physical effects on boys than on girls. These effects, in turn, produce different psychological experiences in the sexes. But male-female differences in personality are not due solely to biology. The environment is equally important. Society tends to treat boys and girls differently from an early age. Mothers and fathers, for example, give boys trains to ...
... of pesticide usage universally, society can never be sure as to the long term effects on our environment and what they are eating or giving to the future of our world, the children. In some foreign countries pesticides are used more frequently with legislative control than in the United States. In Mexico and South America, for example, many of the pesticides that the United States and Europe have banned, wind up being used on a majority of their produce crops. The largest problem with this is that Europe and the United States import from South America for produce all of the time. What good does it do to ban harmful agricultural chemicals to be used on domestical ...
... denies it. I see that he tries to cut down, but he never stops." Many people who drink, try to relieve pressure or soothe their feelings. "Those who stay with the habit, become increasingly dependent on alcohol or drugs, are using these substances as a medication of sorts or a way to soothe feelings of anxiety, anger, or depression," says Daniel Goleman in his book, Emotional Intelligence. Many clubs and organizations around the country including S.A.D.D. (Students Against Driving Drunk) and M.A.D.D.(Mothers Against Drunk Driving) make the public aware of alcoholism through community events and general public information. Adults are not the only group of people ...
... be achieved with a better understanding of background issues, assistive devices, interview techniques and sources of further information. Guidelines for assessment of deaf and hard-of-hearing patients are provided in Table 1. Table 2 provides suggestions for conducting interviews with these patients. Illustrative Case A 60-year-old deaf woman, a native user of American Sign Language, presented as a new referral. During visits with her previous physician, she had always communicated by using her daughter as an interpreter. The referral physician arranged for a certified interpreter and then called the new patient (using the state's relay service) to inform her ...
... someones life is well worth it. A paramedic experiences much stress and sometimes trauma every day that he or she is on the job. The thrill of a paramedic is only part that you get to see, but there is much more involved in this career than you or even I know of. The career of a Emergency Medical Technician involves saving lives. The E.M.S. is only as strong as its weakest link (Caroline,3). During the 1960’s people and associations began wondering if there was any possible way to operate a ambulance and administer pre-hospital care efficiently with some other type of personnel besides a licenced doctor (Caroline,1). By 1970 the question had been answered. ...
... took a turn and began to focus on the “molecule of the year”, as proclaimed by Science magazine. Recently, Nikola Pavelitch of New York's Memorial Sloan-Kettering Cancer Center was able to get a photo of the gene, and she notices that when the disease (cancer) is forming, rogue molecules are present that keep it from performing its good deeds. There have since been 5,200 studies on p53 and researchers are sure it will be a major discovery. The p53's function is as the director to control damage within the cell. When it is healthy, normal cells keep them around and they continue to degrade and replenish themselves. If a high alert is set in the cell due ...
... lasting success. Josef Breuer, a Viennese physician, achieved better results by letting Anna O., a young woman patient, try to empty her mind by just telling him all of her thoughts and feelings. Freud refined Breuer's method by conceptualizing theories about it and, using these theories, telling his patients through interpretations what was going on inside the unconscious part of their minds, thus making the unconscious become conscious. Many hysterias were cured this way, and in 1895, Breuer and Freud published their findings and theories in Studies in Hysteria. CLASSIC PSYCHOANALYTIC THEORY Traditional psychoanalytical theory states that all human beings ...

Hepatogenous jaundice is caused by liver damage, particularly hepatitis. Hepatitis exists in an acute and/or chronic form.
