Melanoma caused by low DNA repair capacity

Melanoma is the deadliest form of skin cancer and it has been shown through previous research studies that the risk is increased by exposure to sunlight, whose UV rays cause damage to DNA that triggers cancer. However, it has not been clear why some people are more prone than others to melanoma. Researchers have now found out through a study involving a group of 312 people with melanoma t...

Measuring Exercise Capacity To Predict Heart Disease

Research shows that measuring the body’s capacity to exercise through cardiac stress tests can predict the risk of coronary heart disease. This and heart rate recovery can improve dramatically on existing techniques // that predict who is most likely to suffer a heart attack or die from coronary heart disease (CHD). In the September edition of the journal Circulation, the Jo...

Genetics of Ageing with Preserved Mental Capacity.

Research conducted by George S. Zubenko, MD, PhD, Professor of Psychiatry and Biological Sciences at the University of Pittsburgh School reported that genes relating to aging with preserved mental capacity have been identified.// This research was the first of its kind and was funded by National Institutes of Health (NIH). The study analyzed 100 individuals who were ninety year...

9/11 Firefighters' Can Regain Lung Capacity: Study

A new study appearing in the American Journal of Respiratory and Critical Care Medicine says that firefighters //at Ground Zero on September 11 had a loss in lung capacity equivalent to what usually happens after 12 years on duty a year after the terror attacks. An average loss of 372 milliliters was noted, which is equal to 6 percent of the lung's capacity. This loss is at least 10 t...

A Human Brain Gene Could Hold Clues On The Evolution Of Brain Capacity

Scientists claimed to have discovered a gene that could hold clues as to the evolution of the capacity of the brain.// The scientists have explained that the gene discovered has undergone a quickened evolutionary change in humans and are active during a vital stage in brain development. The researchers have stated that though they are yet to resolve the precise function of the gene, t...

Genes determine the capacity to fight HIV in early stages

The capacity of an individual's immune system to control HIV infection appears to depend on both the specific versions of key immune-system molecules// called HLA Class I that have been inherited, as well as on the fragments of viral protein those molecules display to the T lymphocytes that usually destroy infected cells. In a report in the November issue of PLOS Medicine, researchers fro...

Dementia Delayed by the Capacity to Speak Two Languages

“The ability to speak two languages can delay the onset of dementia”, claims a research report. This study was conducted by Professor Ellen Bialystok of York University// at Toronto, Canada on 184 elderly patients. Ninety three patients in this group were bilingual while the remaining spoke only one language. The average age in the bilingual group when dementia set in was 75.5 while i...

Kenya, Surrounding Region Lack Capacity To Handle XDR-TB, Experts Say

Kenya and its surrounding region lack the capacity to handle extensively drug-resistant tuberculosis, if the disease spreads to the region. //The TB virus is said to be resistant to two most potent first-line treatments and some of the available second-line drugs, according to some Kenyan medical experts. Treating a case of nondrug-resistant TB requires roughly $400, compared with $1...

Reduced Lung Capacity Linked to Cardiovascular Disease by Inflammation

The New Zealand researchers took measurements of lung capacity and inflammation in 1,000 adults aged between 26 and 32 years. To measure inflammation, they looked at the amount of C-reactive protein (CRP), an inflammatory marker, circulating in the blood. Higher levels of CRP were found in the blood of those with smaller lung capacities. Although increased levels of markers for inf...

Prions Capacity can Be Aggrevated by Solid Particles

According to a new study,the rogue proteins that cause chronic wasting disease (CWD) exhibit a dramatic increase in their infectious nature when bound to common soil particles . Writing in the journal Public Library of Science (PLoS) Pathogens, a group led by University of Wisconsin-Madison prion expert Judd Aiken reports that prions, the protein agents of a family of fatal brain disor...
