Like any other organ, the heart requires a steady flow of oxygen and nutrients to provide energy f .....

.... homocysteine in the blood. Even though many physicians attribute heart related diseases to cholesterol, studies have shown that there may not be a direct correlation between these levels and heart diseases(McCully, 1997). Other risk factors of heart disease include obesity, high blood pressure and smoking. Contrary to past knowledge, most heart attack victims actually have levels 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).

.... yet. Alcohol can cause disorders such as Fetal Alcohol Syndrome and Fetal Alcohol Effects. Fetal Alcohol Syndrome, FAS, is a congenital disorder which is characterized by a variety of physical and behavioral traits that result from maternal alcohol consumption during pregnancy. The term Fetal Alcohol Effects, FAE, indicates that alcohol is being considered as one of the possible causes of a patient's birth defects. In other words, FAE is a less severe form of FAS. Both FAS and FAE are the results of the use of teratogens, which are nongenetic influences that can potentially complicate fetal development.(Harris, p.85) FAS is due to the mother's cons .....

This debate leaves less medically educated people who are not professionals, and who are going by the advice of the people who are, in a bit of a rough spot.

.... leaders of the 21st Century. In my opinion, physicians and others associated with the medical profession will participate in one of the most vital and urgent roles entering into the new era. This is one of the reasons that I intend to pursue a career in the medical field after I graduate from The University of Tennessee. Of all occupations in the next millennium, medicine will be perhaps the most important and influential in combating the problems of mankind and in solving them. People in the field of medicine will continue, as they have in this century, to address and participate in almost all concerns. For example, methadone is currently being used a .....

.... any of the Heavenly Religions appeared. In fact, the most traditional and conservative type of circumcision is the Pharoanic type (Infibulation), where the complete removal of the clitoris occurs and the vulva walls are stitched together leaving a small opening for urination and menstrual discharge. Nowadays, however, it continues to be practiced in Africa and the Middle East mostly due to social forces. New reasoning developed through the years to keep the ritual going on. The many reasons given for the practice are bewildering and unfounded in any scientific or medical fact. They fall into four main categories: psycho-sexual, religious, sociological and hygi .....

.... chances of having a Down Syndrome baby are slim, (1 in 1000) it is still an issue that to-be parents should discuss and prepare for. People with Down Syndrome are identified by many physical characteristics. Some of these are: larger or almond shaped eyes (sometimes Brushfield spots on the irises), smaller than normal features, such as smaller ears or a smaller nose, short stubby fingers, a single palmar crease on their hands, and having exceptional social intelligence.
