... eye surgeon cleared up the myth that dyslexia is caused bye vision problems. There are many distinct types of dyslexia, but there is not just one particular cause of dyslexia. The causes are usually a combination of both biological and environmental influences. The left part of the brain controls the production and comprehension of language and it also deals with orderly and precise thought. The right part of the brain controls visual perception, emotion, instincts, and non-verbal responses. Both the right and left part of the brain must work together to create speech, writing, and mathematics. Some scientists say that the cause of dyslexia don’t have ...
... to be normal and she can therefore compensate for this defect. There are two types of haemophilia, haemophilia A and B. Haemophilia A is a hereditary disorder in which bleeding is due to deficiency of the coagulation factor VIII (VIII:C)3. In most of the cases, this coagulant protein is reduced but in a rare amount of cases, this protein is present by immunoassay but defective. Haemophilia A is the most common severe bleeding disorder and approximately 1 in 10,000 males is effected. The most common types of bleeding are into the joints and muscles. Haemophilia is severe if the factor VIII:C levels are less that 1 %, they are moderate if the levels are 1-5 ...
... 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). 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. Conventionally speaking, the blockage of LDL would be the onset of a very fatty diet. However, it has ...
... into sugars in the human digestive system and then course through the blood stream fueling muscles and nerves. Rather, when eaten they tumble intact through the stomach and small intestine and end up in the colon where billions of bacterial feed on them - in turn producing intestinal gas. No wonder, then, that dietary fibre has been unwelcome in many of history's nicer neighborhoods. Even 20th century doctors reasoned that since the bulky material provided not a single nutrient, it would only strain already troubled guts. Accordingly, they recommended low-fibre diets for patients suffering from hemorrhoids and other colon disorders often found in the West. ...
... The formation of a clot (or thrombus) in the region of this plaque can block the flow of blood to part of the heart muscle and cause a heart attack. If a clot blocks the flow of blood to part of the brain, the result is a stroke. A high level of LDL reflects an increased risk of heart disease. That is why LDL is often called "bad" . comes from two sources. It’s produced in your body, mostly in the liver (about 1,000 milligrams a day). And it’s found in foods that come from animals, such as meats, poultry, fish, seafood and dairy products. Foods from plants (fruits, vegetables, grains, nuts and seeds) do not contain For some people, exercise affects blood c ...
... corpus luteum deteriorates causing uterine contraction to expell the endometrium. However, if the egg is fertilized the level of estrogen and progesterone must remain high so the endometrium is not shed. The outer layer of the egg mass(blastocyct) produces a hormone(HCG) to maintain the corpus luteum for the first 3 months of pregnancy so it can provide high levels of estrogen and progesterone. After the third month the placenta provides enough estrogen and progesterone to maintain the endometrium and also to inhibit further ovulation. Conception is when the egg and the sperm meet in the oviduct to form the zygote. If the egg or the sperm have any chromosome abnor ...
... water or drinking water due to the fact the grounds acidic or if it's soft enough. Either way it stays a long time on the soil or in water. Months or years down the road after the lead has built up it starts to become a problem for children that play outside of their homes (Xintaras, 1993). These lead containing soil particles get on the child's hands or clothing and end up in the child's mouth. After the build up of so much lead it leads to a problem commonly known as lead poison. Lead poisoning has been an issue since the early 1900s, when the use of lead started being banned from the manufacturing of paint in foreign countries such as Australia(Monheit, 199 ...
... from the beginning of the earliest civilizations as a tool to conquer, kill and destroy and it was usually used as a justification of those actions. People were not responsible for the killings, instead gods were. When people can not handle problems, which arise every day in front of them, they try to hide under the mask called god, but by doing that they do not solve them, they only ignore and try to escape their everyday problems, which makes everything worse. The desperate attempt to explain their own existence took people to the creation of many various myths, which also incorporated in them many different aspect of the culture and everyday life of their creator ...
... before the tissues become irreversibly damaged. Because of this preservation restriction, the donor heart is ultimately given to someone whose tissues do not match up as well, so there is a greatly increased chance for rejection of the organ by the recipient. As far as the man in Oregon goes, he will probably not receive a donor heart before his own expires. Currently, when a heart is being prepared for transplantation, it is simply submerged in an isotonic saline ice bath in an attempt to stop all metabolic activity of that heart. This cold submersion technique is adequate for only four hours. However, if the heart is perfused with the proper media ...
... due to violent crimes. This is not surprising that young males commit most of the serious crimes. According to an article in Scientific American, only 12.5 percent of violent crime in the U.S. in 1992 was committed by females. What is also surprising according to W.W. Gibbs the author of "Seeking the Criminal Element," in Scientific American,(1995 March) pp 100-107, is that a very small number of criminals are responsible for the majority of the violent crime. Sullivan who is now the president of the Morehouse School of Medicine in Atlanta wanted to try and address the violence as a public health issue. In an interview after he left office in 1993, Dr. Sullivan e ...
