... of cells that are being made in period I, is the plasma cell, a specialized antibody factory. It can make up to 30,000 antibodies a second. The second type of cell being made in period I is a memory cell. They also produce antibodies, however they live for long periods of time (up to a lifetime), compared to a plasma cell that lives only a few days. Memory cells are made so they can recognize this same antigen if it were to ever reenter the body again. Interactions between T cells are also known as the cell-mediated response. T cells are not just active against viruses and bacteria, but they also interact with eukaryotic cells. There are three types of T ce ...

... the surface of the skin. Second are the basal cells and finally are the melanocytes, which give the skin its color. The second layer of skin is the dermis, which is much thicker than the epidermis. This layer contains sweat glands, nerves and blood vessels. The dermis also contains follicles, which are tiny pockets from which the hair grows. The most common malignant cells are the basal cells. Cancer in the basal cell is called nonmelanoma cancer. This means that the cancer did not start in the melanocytes located in the epidermis. Basal Cell Carcinoma is caused by overexposure to the sun. The sun gives off ultraviolet rays, which are harmful to the human ...
... the lower needs, and the upper point representing the need for self-actualization. Each level of the pyramid is dependent on the previous level. For example, a person does not feel the second need until the demands of the first have been satisfied. 1. Physiological Needs. These needs are biological and consists of the needs for oxygen, food, water, and a relatively constant body temperature. These needs are the strongest because if deprived, the person would die. 2.

The U.S. Public Health Service estimates that in 1993, the lifetime cost of treating a person with AIDS from infection to death is approximately $119,000. Outpatient care, including medication, visits to doctors, home health aids, and long-term care, accounted for approximately 32 percent of the total cost. Persons exposed to HIV may have difficulty in obtaining adequate health-insurance coverage. Yearly AZT expenses can average approximately $6,000, although in 1989 the drug's maker did offer to distribute AZT freely to HIV- in ...
... infections are treated with antibiotics, Mostly with aerosols that relieve constriction of the airways. Physical therapy Is used to help patients cough up the obstructing mucus. Intestinal obstruction, Which occurs mostly in infancy, may require surgery. In 1989, researchers fond the abnormal gene that causes cystic fibrosis. This gene is located on chromosome 7 . A person who has two cystic fibrosis Genes has the disease . A person that carries one of the genes does not have the Genetic disease, but is a carrier. The symptoms of cystic fibrosis sometimes occur immediately after birth. Mucus secretions may appear in the baby’s intestines, which can cause Obstr ...

For instances, in one lab animal the researcher cut through the axis of the brain at one level, which would prevented the animal from awakening; showing that brain structures below the level of the cut were responsible for awakening the lab animal. The American Sleep Disorders Association (ASDA), Association for the Psychophysiological Study of Sleep (APSS), Association of Sleep Disorder Centers (ASDC), and the American Psychiatric Association (APA) has studied sleep and sleep disorders since the early 1970's.
