.... Sleep is regulated by a connected series of structures in the deep midline areas, and along other way stations that extend through the central axis of the brain, these structures relay information about things that affect sleep. In Dr. Regestein notes, he spoke of experiments that were performed by researchers. The researchers he spoke of would destroy specific brain structures of a lab animal and then note how the animal slept. 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 .....

.... is the environment you live in. The environment you are in may affect how you develop. For instance, if you have a talent for music, but have no way to acquire instruments, then it is doubtful that you will ever discover your talent with music. Physically, you may have great potential as a runner, but, if you do not get enough to eat, then it is doubtful that you will ever live up to your potential. Traits such as what you look like are inherited from your parents. Your potential is also inherited from your parents. Chromosomes contain the information of a person's potential height, potential strength against disease, and other physical characteristics. A .....

.... rejection preventative, that would alter the immune system so that it cannot destroy the transplanted tissue. Research has shown to work in various patients for different time periods, showing a hope for the procedure in the future. Pigs were found to be the best donors in this process. Pigs are easily raised, have similar organs that are 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. coul .....

Psychological changes may come in changes of mood and diseases that are due to aging. is the cessation of menstruation cycles, it begins sometime in the middle forties, for most women it serves as a biological age marker in many societies for the start of advancing age. The direct cause of is a steady and continuing decline in the production of estrogen by aging ovaries. This decrease along with other hormonal changes has some side affects. One major consequence is vasomotor instability. Other wise known as hot flashes, these may occur when sort burst of capillary expansion that cause a warm flushed feeling around the neck or head these .....

.... Louise Brown. (Dreher 1). Louise Brown was the world's first "test-tube baby," denoting one of the greatest marvels of 20th century science. However, the medical phenomena of being able to fertilize an egg outside of the body, a technique known as in vitro fertilization (IVF), has also become a high-tech dilemma. A number of ethical concerns have been raised since Louise Brown was born 16 years ago, causing many people to question IVF as a morally acceptable means of conception. Among these concerns are the following: (1) Is IVF morally unacceptable because it is an "unnatural" means of conception? (2) Does IVF threaten the moral status of women? .....

.... for example, if after eating a large fairly acidic food, and lying straight back, the acid moves back from the stomach. Also, if you lean over while working, pressure builds in the organs, pushing the acids upwards. Heartburn is often very uncomfortable for the individual who has it. There are not many symptoms, but the ones most commonly found are, a burning sensation in the chest and upper abdomen, sore throat, and when the mouth sometimes fills with a liquid called water brash. Heartburn has many affects on the body, but I will focus now on the effect on the digestive system. Heartburn causes ulcers, which eat through the mucous layer of the organs in t .....

.... set up, physically or therapeutically, to benefit the cognitively impaired resident. Current nursing home regulations provide for “warehouse-style” settings and are in most cases not therapeutic to the Alzheimer’s or dementia resident. Many of these regulations border on abusive for the dementia patient (Johnson 11). Some nursing homes are beginning to respond to this growing issue by developing 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 benefi .....

.... 1978). The drug is PCP, and to this day it is the scourge of the underground drug community, and the focal point of intense scientific research. Parke Davis and Company did not know how terrible, and wonderful, a discovery they made that day; but our world has been changed forever because of it.quite possibly for the better. The Dust of Angels Phencyclidine, more commonly known as PCP, is a polycyclic compound belonging to the arylcyclohexylamine class of chemicals [figure 1.0] (Souza 1993). In pure form, it is a white powder which readily dissolves in water. The cyclohexamines are known for their the potent neurological effects, with PCP being the most .....
