The use of prescribed burns to manage Western forests may help the United States reduce its carbon footprint. A new study finds that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size.

Anti-obesity drugs unlikely to provide lasting benefit, according to scientists
18.03.2010 13:00 0 views 0 comments Tags: Scientists
Scientists argue that anti-obesity drugs fail to provide lasting benefits for health and well-being because they tackle the biological consequences of obesity, and not the important psychological causes of over-consumption and weight gain. Read more »

One year post-surgery, patients who underwent Descemet's stripping automated endothelial keratoplasty (DSAEK) experienced greater cell loss overall compared to those who underwent penetrating keratoplasty (PKP), according to a new analysis of data. However, the study showed that cell loss in DSAEK patients plateaued more quickly than in those who underwent PKP. Read more »

If you take simvastatin to control cholesterol, watch out for infection, says new report
18.03.2010 4:00 0 views 0 comments Tags: Scientists, First, This, First
Simvastatin might help us control our cholesterol, but when it comes to infection, it's an entirely different story says a new research study. Scientists have shown that simvastatin delivers a one-two punch to the immune system. First it impairs the ability of specialized immune cells, called macrophages, to kill pathogens. Then, it enhances production of molecules, called cytokines, which trigger and sustain inflammation. Read more »

Scientists have studied interactions between the loggerhead turtle (Caretta caretta) and fishing gear such as longline hooks used at the water surface, mass beachings, and the effects of climate change on these animals. In order to reduce captures of this marine species without causing economic losses for fishermen, the scientists are proposing that fishing in the summer should only be carried out by night and in areas more than 35 nautical miles from land.

Spanish researchers determined that rats treated with recombinant ghrelin displayed a reduction in liver fibrosis. Ghrelin, a stomach hormone, reduced the amount of fibrogenic cells by 25 percent in the treated rodents. Research further showed ghrelin prevented acute liver damage and reduced oxidative stress and inflammation in the animal models. Read more »
