Man-made CFCs Are Jeopardizing Our Future
.... in the stratosphere (Gutnik 54). CFCs are most commonly used as the propellant in spray cans, the coolant in refrigerators and air conditioners, in foam and plastic insulation, and in industrial solvents (Caldara 20).
Industry began using CFCs in the World War II era. In 1973, atmospheric chemists F. Sherwood Rowland and Mario Molina of the University of California at Irvine postulated the connection between ozone depletion and CFCs. Although CFCs were found to be harmful to the ozone twenty three .....

Diet And Disease
.... in moderation and those to be liberally consumed.
It is stated by Newkarm that general health requires that the total intake of all fats, especially animal fats is reduced. Fatty deposits in the arteries and gallstones are to a large extent made up of cholesterol (19). When foods high in fat content are eaten, excessive amounts of cholesterol are made in the body. Individuals who have fat concentrated in the waist and abdomen instead of thighs and buttocks are prone to diseases that accompany obesi .....

Antibiotics
.... Antibiotics Work ?
Antibiotics 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 bac .....

Xenotransplantation
.... comparable in size and physiology to that of humans. Further more, pigs are free from the known pathogens that would put the general human population at risk, and few would voice ethical concerns about them being slaughtered for transplants since they are currently being killed for human consumption.
Xenotransplantation could affect the overall quality of human life, if perfected. People would suffer less from hemophilia, diabetes, Alzeimers, Parkinson’s diseases, and aids. People would no longer .....

Psychological Stress
.... of certain goals or needs (Corey 207). All of the little things that frustrate us include waiting in lines or traffic, sense of failure or inadequacies, bad relationships, deaths, and loneliness. Self-defeating thoughts are a way in which we almost deliberately block attainment of our needs. If in our heads, we have this preconceived notion that we are incapable of obtaining something that we want or that others could not possibly love us, we create a self-fulfilling prophecy. I used the word "deli .....

Effects Of Drugs On The Body
.... Drug dependence is both psychological and physical. Psychological dependence involves a craving for the psychological experience a drug provides. Physical dependence means that the user builds a tolerance to the drug. When this happens the user needs more and more of the drug to achieve the same effect.
If a person develops this type of tolerance and then stops using the drug he/she will suffer from drug withdrawal. The body then needs the drug so badly that the user will seek even more of the .....

The Brain
.... known as hemispheres. These hemispheres are connected by bundles of nerve fibres. Each of theses hemispheres are divided into 4 regions names as the bone of the skull that lies above it. The outer layer of the cerebrum is called the cortex. The cortex is mainly made up of nerve cell fibres. The cerebrum cortex is folded into a surface with many ridges and grooves. This folding greatly increases the surface area of the cortex and the number of nerve cells it contains within the limited space of the .....

Managing People With AIDS
.... with AIDS. However, HIV and AIDS pose special challenges to employers.
HOW AIDS IS TRANSMITTED
HIV (Human Immunodeficiency Virus) is the retrovirus that causes AIDS, or Acquired Immune Deficiency Syndrome. While AIDS itself does not kill a person, the disease weakens the person’s immune system, allowing other diseases like Kaposi’s sarcoma invade the body. These opportunistic diseases eventually overwhelm the person’s body. The virus is found in blood and other body products like saliva, swe .....

Heart Attacks And Its Causes
.... of cholesterol that would be considered normal, and as many as one fourth of heart attacks occur in people with no known risk factors at all (Cowley, 1997).
The hypothesis that high levels of cholesterol cause heart attacks may be attributed to this: LDL, or "bad" cholesterol, induces cells to produce proteins in the arterial walls of the heart and the veins leading to the heart. Macrophages eat the fatty substances in the heart and then die, causing a build up in the veins. Conventional .....

Demanding Greatness: Steroid Use

“There are many reasons why people use steroids. But the two main ones are to excel in athletic competition and to look more like one’s ideal of a perfect body.”4 Many athletes are representing their school, state, or territory they come from at the competitions they are involved with. Most of these competitors don’t want to let down their fans in fear .....

Fetal Alcohol Syndrome
.... Alcohol attacks virtually any of the body's cell (Dorfman, 60). Mid-facial abnormalities are a part of the child for life. Some of these common abnormalities are a broad nasal bridge, poorly developed filtrum, thin upper limit, flattening of the axillary area, and a short upturned or beak-like nose.
Some of the more serious effects that can be more dangerous are a poor dental alignment, optic nerve defects, and arterial septal defect (Welkselman, 297). Welkselman thinks that fetal alcohol sy .....

Alzheimer’s Special Care Units
.... distinct units, innovative in their design and operations. These new units are dementia special care units and are necessary to the treatment and well being of a resident with Alzheimer’s disease or a related forms of dementia.
In order to understand what benefits a person will receive from a special care unit, we must first examine what dementia is. When most people think of Alzheimer’s disease and related dementias, probably the first symptom to come to mind is forgetfulness of memory loss. W .....

Addiction And Heath Professionals

The problem concerning addicted health professionals seems to affect the public as most of us seek healthcare at one time or another in our lifetimes.
First, the definition of impairment must be addressed. According to the American Medical Association’s Council on Mental Health, impairment is "the inability to practice medicine with reaso .....

Those skeptical about the value of alternative medicine claim that the Office of Alternative Medicine (OAM) does not take the proper unbiased, scientific stance but acts instead as an advocate for alternative medicine. Skeptics point to studies .....

Vegetarianism
.... a diet. In each case it can be a healthy or a harmful way to eat. The benefits or harm of vegetarianism is associated with two factors: education about nutritional needs coupled with food choices. Even groups like athletes can thrive on a vegetarian diet if they are well educated to the bodies' dietary needs and are well aware of the limit-less choices available on a vegetarian diet. What follows in this essay, is first: a brief, yet insightful look at the vegetarian diet (the nutritional aspect) and t .....
