Vitamins and Cardiovascular Disease
A recent study on has cast doubt on the effectiveness of high doses of vitamins to help prevent heart disease in men. The study was conducted on 14 000 doctors. The physicians participated in the study for almost a decade and took high doses of C and E. The study concluded there was no proof that either C or E made a difference in the prevention of cardiovascular disease.
Genetically Modified Pigs to Produce Human Organs
According to UNet an online database system developed by UNOS(United Network for Organ Sharing)nearly 100,000 people are on the waiting list for organ transplant in the US alone. This research may bring them some hope in the new future. Scientists researching on genetically modified pigs believes that the first human transplant of an organ grown in a humanized pig could take place in the next decade. These pigs are genetically modified to contain 6 human genes that partially “humanize” them in order to prevent rejection by the immune system of organ recipients.
Women more prone to Strokes
When blood flow to the brain is suddenly disrupted by a clot or a burst vessel brain damage occurs and it is called stroke. There are 700 000 people each year who suffer stroke. According to a research, women account for 60 percent of death caused by stroke. The chances of stroke is increased by birth control pills and pregnancy. Migraines, also have been linked to strokes.

Out-of-body experience To be Researched
Out-of-body experience has been reported in several incidents by people who cheat death at the last moment. Around 10 to 20 per cent of people whose heart stops after a cardiac arrest report some near-death experiences. But its never been scientifically proved whether they are real or just a trick of the mind. Scientists in UK are to examine the near-death experiences of 1,500 hospital patients to find out the truth. The research will be carried out for the next three years. Pictures will be placed on shelves high up in hospital rooms so that they can be seen only from above. If any patients recall the images, it would be the first hard proof that out-of-body experiences are real.
Wide Disparities in Health Care by Race and Region
Most of us would agree race could be a determining factor in the quality of service a person gets. But a new study shows place of residence could play a role in quality of the medical treatment a patient receives. According to a new study in United States that women in Mississippi are far less likely to have mammograms than those in Maine. The study also revealed that blacks with diabetes or vascular disease are nearly five times more likely than whites to have a leg amputated. “In U.S. health care, it’s not only who you are that matters; it’s also where you live,” wrote the study’s authors, led by Dr. Elliott S. Fisher.

Moisturizers Can Cause Skin Cancer!
According to a new study by researchers at Rutgers University in New Jersey, several commonly used skin creams may cause skin tumors. Dr. Allan Conney and colleagues stumbled across the findings after they exposed hairless mice to ultraviolet radiation to mimic sun exposure. Afterward, they applied four popular moisturizers to the mice. They found all four moisturizers caused tumors to grow on the mice. However, this study does not confirm that people using moisturizers are exposed to the same risks as mice were.
Down Syndrome In A Dish
Harvard scientists have created stems cells for 10 genetic disorders. These stems cells will allow these researchers to watch the diseases develop in a lab. This new technique could help to find treatments for some of the genetic diseases. Dr. George Daley and his colleagues at the Harvard Stem Cell Institute produced these stem cells by using skin cells and bone marrow from people with diseases such as Parkinson’s, Huntington’s and Down syndrome. The new technique of re-programing cells gives these cells the qualities like embryonic stem cells, which can morph into all kinds of tissue, such as heart, nerve and brain. So researchers can see progression of each diseases in a dish. This technique can help to find a cure by knowing what goes right or wrong in a dish.

Bad Guys Get More Girls
Bad boys get the most girls,the finding is backed by two new studies. People with antisocial personality traits known as the “dark triad”,self-obsession of narcissism; the impulsive, thrill-seeking and callous behaviour of psychopaths, have a prolific sex life. The finding may help explain why antisocial personality traits exists in the human population. One study was conducted among 35,000 people in 57 countries.
New Brain mapping technique
Neurosurgeons from the University of California, San Francisco are reporting significant results of a new brain mapping technique that allows for the safe removal of tumors near language pathways in the brain. The technique minimizes brain exposure and reduces the amount of time a patient must be awake during surgery.
Language mapping, originally created to help guide epilepsy surgery, has proved to be an essential tool in helping neurosurgeons identify which parts of the tumor can be safely removed and in protecting patients from damage to speech and language centers.
Earlier it was estimated that 20,500 men and women will be diagnosed with, and 12,740 men and women will die of, cancer of the brain and other areas of the nervous system in 2007, according to the American Cancer Society.
