Researchers have new insight into the mechanisms that underlie a pathological increase in the size of the heart. The research, published by Cell Press in the October 24th issue of the journal Molecular Cell, may lead to the development of new strategies for managing this extremely common cardiac ailment that often leads to heart failure.

Researchers from the Genome Institute of Singapore (GIS) and its collaborators have now identified for the first time a new gene that may confer susceptibility to pulmonary tuberculosis. Their findings, published October 10 in the open access journal PLoS Genetics, reported that a gene named Toll-like receptor 8 (TLR8), previously shown only to recognize some factors from viruses such as the human immunodeficiency virus (HIV), has a probable role in human susceptibility to Mycobacterium tuberculosis infections. The results from the study also found that males are more susceptible than females. Continue reading “Scientists identify gene that may make humans more vulnerable to pulmonary tuberculosis”
You know it’s good for you in other ways, but could eating your broccoli also help patients with chronic lung disease? It just might.
According to recent research from Johns Hopkins Medical School, a decrease in lung concentrations of NRF2-dependent antioxidants, key components of the lung’s defense system against inflammatory injury, is linked to the severity of chronic obstructive pulmonary disease (COPD) in smokers. Broccoli is known to contain a compound that prevents the degradation of NFRP.

A new study has shown that an investigational drug (R207910, currently in clinical trials against multi-drug resistant tuberculosis strains) is quite effective at killing latent bacteria. This revelation suggests that R207910 may lead to improved and shortened treatments for this globally prevalent disease.

For patients with clogged heart arteries who take long-term, low-dose aspirin to prevent a cardiac event, adding a stomach acid-blocking drug to their daily routine has been shown to reduce their risk for upper gastrointestinal bleeding – an infrequent, but serious side-effect of regular aspirin use.
But do the benefits of these acid blockers – called proton pump inhibitors, or PPIs – outweigh their long-term costs?
In a new study, researchers at the University of Michigan Health System reveal that, from the perspective of a long-term payer, over-the-counter PPIs are worth the price for coronary heart disease patients taking low-dose aspirin as a preventative measure. At prescription costs, however, PPIs are cost-effective only for elderly patients and patients at high risk for upper GI bleeding.

Using a breakthrough technology, researchers led by a Weill Cornell Medical College scientist have pinpointed the hormone estrogen as a key player in about half of all prostate cancers.
Estrogen-linked signaling helps drive a discrete and aggressive form of the disease caused by a chromosomal translocation, which in turn results in the fusion of two genes. Continue reading “Estrogen helps drive distinct, aggressive form of prostate cancer”
