.... more heavily than other age groups. It is often difficult to distinguish such heavy and abusive drinking from the early stages of alcoholism. How well the person can tolerate giving up alcohol for an extended time and the effects of drinking on the family, friends, work, and health, may indicate the extent of the alcohol problem. More than ten million Americans are estimated to be alcoholic. Alcoholism is found in all ages, cultures and economic groups. It is estimated that 75 percent of alcoholics are male and 25 percent are female. Alcoholism is a worldwi .....

.... weak. TB can attack any part of the system. The lungs are the most common area of attack. People with the TB disease have one or more of the following symptoms: a cough that hangs on, fevers, weight loss, night sweats, constant fatigue, and loss of appetite. A person with the TB disease in the late stages will cough up blood streaked sputum. People who have Active TB disease usually only have mild symptoms. There are three tests to diagnose TB disease. One is the Tuberculin Mantoux PPD skin test; two is a Chest X-ray which is given after the Skin test is .....

.... of minced pancreas from unrelated donor rats for one year while a control group was left untreated. Then both the treated and control groups received injections of approximately 500-800 islets of Langerhans from unrelated donors. Of the five treated animals, two became clinically and biochemically permanently normal. Six months later, Martin examined the cured rats and found intact, functioning islets secreting all of their hormones, including insulin. None of the controls were cured. Encouraged by their first results, Leibel, Martin, and Zingg decided to repe .....

.... 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 eff .....

.... and elections by dividing those who support and those who consider it a form of murder. It also has been a topic that has divided the Christian community. A movement began in the 1970's when Americans started to demand "death with dignity" (Worsnop 1). In the event of a terminal illness or injury, people were refusing life-sustaining treatment to preserve life, especially life without quality. Public opinion overall supports some form of assisted suicide. Because of this support, most states have some form of legislation that allows for "living wills" .....

.... the brains of Alzheimer's victims. They are found within the cell bodies of nerve cells in the cerebral cortex, and take on the structure of a paired helix. Other diseases that have "paired helixes" include Parkinson's disease, Down's Syndrome, and Dementia Pugilistica. Scientists are not sure how the paired helixes are related in these very different diseases. Neuritic Plaques are patches of clumped material lying outside the bodies of nerve cells in the brain. They are mainly found in the cerebral cortex, but have also been seen in other areas of the brain. At .....

.... to the host. Most pathogens we are familiar with today fall into the latter category. In this case, virulence of the pathogen can, and is, measured by mortality rates. Here, more virulent strains kill more hosts. If mortality rates are very low or not present at all, greater virulence can be expressed as causing more symptoms of illness. One such pathogen is Vibrio cholerae, which causes the disease known as cholera. The subject of this paper will focus on the V. cholerae pathogen and the significance of its presence on Earth. I will examine virulence .....

.... (Myers 260). With Pavlov's new observations a new set of stimulus and response was found. This new set is known as the conditioned stimulus and the conditioned response. What is meant by conditioned response here is that the response was learned. The stimulus begins as neutral and causes no conditioned response. However, if the neutral stimulus can be associated with another stimulus, then it becomes a conditioned stimulus. Classical conditioning can be exemplified in the home, school, and school. In the home a child could smell brownies baking in t .....
