.... when oxygen is released by the red blood cells in people with , the cells become distorted, forming a rigid banana or sickle shape that can clog blood vessels. Sickle cells tend to become trapped and destroyed in the liver and in the spleen. This results in a shortage of red blood cells called anemia which, when severe, can cause the patient to be pale, short of breath and easily tired. Certain conditions, such as infections, may worsen a patient's anemia by speeding up destruction of red blood cells or reducing red blood cell production. Two of the most common forms of are sickle cell anemia (SS disease) and sickle "C" disease. Sickle beta thalassemia is a l .....

.... of AIDS. This sees the disease as a process in which cells of the immune system that guard against infection become wrongly programmed and start killing themselves they are not killed by the virus, as had been thought. But Duesberg, professor of molecular and cell biology at the University of California at Berkeley and a member of the American National Academy of Sciences, goes further. HIV is not a new virus, he says. It is perhaps "as old as America". It is carried by a small, fairly constant proportion of the population and is harmless. It is present in many AIDS patients because most of them have risk factors in their lives such as drug abuse, sexual b .....

.... are considered normal and do not interfere with strength, joint mobility, endurance, or any other body function. They are not true , and do not increase the likelihood of developing back pain, arthritis, disc herniation, or any other musculoskeletal problem. Treatment of scoliotic curves of ten degrees or less is unnecessary; sometimes these curves may correct themselves (. 1997). However, curvatures that measure between ten and twenty degrees bear watching (Rosenthal, Mark S. MD : A sensible approach. 1997). These behave much the same as those under ten degrees, except that they may progress during growth. Therefore, if a patient has finished growing .....

.... in different ways. It also depends on what kind of society and atmosphere you live in. Not everyone attempts suicide when faced with unbearable situations. Some people cannot cope with it as others can and they feel suicide is an easy way out. It is a known fact, that in today¡¯s fast moving world there is so much of competition everywhere in every field. Every day we hear cases of adults, teenagers, and even children being pushed around to their best. It brings out the best in some people but not everyone. Those who are pushed to their limits and cannot cope with it feel let down by themselves. They feel as if they are not wanted anymore by the society. .....

.... to external stimuli and control our thoughts and behavior. When we're asleep, acetylcholine - producing cells in the lower brain trigger bursts of electrical activity that radiate up to the cortex, which makes sense of these signals by reaching into it's memory file for images, information and experiences and weaving them into a story (Kopecky,76). Psychiatrist and philosopher Gordon Globus of the University of California at Irvine, says to determine what kinds of stories they are and to figure out what they can tell us. He says "you need to look beneath the surface of a dream to find the coherence" (78). Since 1853, when REM, or the dream state, was f .....

.... is installed in a vehicle, mounted on the roof or rear window. Communication between a mobile telephone and the nearest base station is achieved by the microwave emissions from the antenna. Concerns have been raised about the type of mobile telephone that has the antenna in the handset. In this case, the antenna is very close to the user's head during normal use of the telephone and there is concern about the level of microwave emissions to which the brain is being exposed. Those telephones that have the antenna mounted elsewhere are of no concern, since exposure levels decrease rapidly with increasing distance from the antenna. Cordless telephones, wh .....

.... The 'orthodontically' challenged are always the center of electricity and lip-locking jokes. The dentist's office is also a source of embarrassment. Most offices are filled with other patients and operating rooms are easily accessible making it easy for others to watch the pain and embarrassment the patient has to goes through. If one should forget to brush their teeth before their visit, they will regrettably become immortal as the doctor announces the left-over remains of a Turkey and Cheese sandwich stuck between the molars. Braces become a constant source of embarrassment. Braces are three to four years of physical torture beginning with the very .....

.... a complete definition of eclampsia we must define pre-eclampsia. Pre-eclampsia does not have chronic hypertension but becomes hypertensive in late pregnancy. With pre-eclampsia a woman doesn't experience a coma or convulsions, her blood pressure returns to normal after delivery. Although the majority of women who experience pre-eclampsia never get eclampsia-if the blood pressure gets out of hand suddenly, the disease may progress to eclampsia. Eclampsia is pre-eclampsia that has progressed to the point of convulsions and possible coma. Resulting in retardation for the child with lack of oxygenation and other proteins to fetus. A term that must be know .....
