Washington, Sept 19 : Researchers at the University of Toledo in Toledo, Ohio have identified a panel of 15 genes that could serve to predict lung cancer.

If enough of their collective activity becomes ‘too quiet’, it could mean they are being suppressed by other factors in the cell, a step that may lead to cancer.

According to lead researcher, James C. Willey, M.D., a test for these genes, in normal cells sampled via bronchoscopy, could serve as a technique to identify those individuals genetically at risk for lung cancer.

Washington, Sept 19: According to a study, those who stay in school for a longer time period have the best chances of remaining healthy, as education majorly influences income, thus enabling people to live a healthier lifestyle.

The researchers say education influences occupation, income and wealth — and with higher education come healthier behaviors, such as good diet, increased physical activity, reduced stress and better use of preventive and therapeutic healthcare.

Washington, Sept 19 : A mathematical model developed by researchers at University of Pittsburgh School of Medicine to predict the public-health impact of pre-exposure chemoprophylaxis (PrEP) – an HIV prevention strategy that uses antiretroviral drugs, has found that giving a daily antiretroviral pill to people to prevent HIV could profoundly slow the spread of the infection in sub-Saharan Africa.

The strategy is based on the hypothesis that HIV transmission can be curtailed if treatment is given before exposure to the infection occurs.
