Blood flow in brain takes a twist, affecting views of Alzheimer's
New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease. In a paper to appear in the February issue of Nature Neuroscience and now available on-line,...Genes affecting blood pressure change as children become adults
As children transform into adults some of the genes involved in controlling their blood pressure change as well, according to a study of more than 500 pairs of twins. The study of black and white identical and fraternal twins showed that changes in gene expression between ages 14 and 18 accounted for up to one third of the blood pressure variation that occurred by age 18, says Dr. Harold S...CHAVI announces international search for genes affecting HIV response
A pioneering collaboration among U.S., European and Australian researchers announced June 20, 2006, will seek to identify genetic differences in the way people respond to HIV. Suppor...More than drought affecting wheat yields
Wheat producers have more than the drought cutting into their yields this year, said two Texas Agricultural Experiment Station researchers. Dr. Tom Allen, Experiment Station assistant research scientist and plant disease diagnostician, saw more than 150 wheat samples sent to the Great Plains Diagnostic Network lab this growing season, in addition to 400-plus samples the plant pathology sta...Creating new life forms that may help eradicate cancer affecting women
Instead of using the usual cancer-fighting modalities, surgery, chemotherapy, or radiation, researchers from a drug development company called Advaxis, have embarked on a novel approach to fighting cancer: Engaging the immune system to attack cancer in the same the way it would a flu vaccine, by creating new life forms. Dr. Vafa Shahabi, Advaxis' Director of Research and Development, repo...WHO says damage to eco systems are affecting human health
In the report titled Millennium Ecosystem Assessment, scientists have said that degradation of the eco systems// of the world are having a detrimental effect to human health and may cause greater harm in next 50 years. Diseases such as malaria and cholera are threatening to cause a major outbreak and new diseases are emerging because of 60% of the beneficial factors of the eco system a...Hearing Problems Of Middle Age Are Affecting The Younger Generation
Researchers from Purdue University say that cell phones and portable digital music systems are the reason why more and more young people are having hearing problems that are typical of the middle and old ages.// "We're starting to see hearing loss in young adults that we expect to diagnose in middle-aged adults," says Robert Novak, director of clinical education in audiology and associat...Fat Consumption Could Play A Vital Role In Affecting A Child’s Memory
Based on findings of a recent study researchers say children with a higher energy intake from polyunsaturated fatty acids were more likely to have better results in the digit span test, a commonly used measure of short-term // memory and cholesterol intake appeared to reduce performance in the memory test. The researchers analyzed intake of different types of fat in 3,666 children age...Passive Immunotherapy Could Prevent Avian Flu from Affecting Humans
According to a pilot study conducted by Jiahai Lu, Ph.D., of the school of public health at Sun Yat-sen University said that passive immunotherapy// is the best way to treat highly pathogenic avian influenza in humans. Passive immunotherapy uses antibodies from horses. Purified antibodies to the H5N1 strain of avian influenza are derived from horses were used against mice and it proved...Deterioration of Air Quality Affecting Children's Health
The deterioration of Hong Kong’s air quality has resulted in increasing number of children admitted to hospital with breathing problems.// The deterioration of Hong Kong’s air quality has resulted in increasing number of children admitted to hospital with breathing problems. Researchers at Hong Kong University have found that a rise in pollutants such as sulphur di...
