The air we breathe out can help us improve the quality of the air we breathe in. But to do so, one needs a reliable way to calculate the concentration of carbon dioxide we produce indoors. Researchers have developed a new computation method that uses well-established concepts from the study of human metabolism and exercise physiology to significantly improve how this important data is derived.
In an analysis of Medicare billing data submitted by more than 2,300 United States physicians, researchers have calculated the average number of surgical slices, or cuts, made during Mohs micrographic surgery (MMS), a procedure that progressively removes thin layers of cancerous skin tissue in a way that minimizes damage to healthy skin and the risks of leaving cancerous tissue behind.
Although most topical steroids prescribed to patients were generic in a new American study, there was a sharp increase in Medicare Part D and out-of-pocket spending for elderly patients taking these drugs.
Conventional wisdom has held that tropical forest growth will dramatically slow with high levels of rainfall. But researchers turned that assumption on its head with an unprecedented review of data from 150 forests that concluded just the opposite.
Testosterone makes men less likely to realize when they're wrong, a new study shows. The researchers found that men given doses of testosterone performed more poorly on a test designed to measure cognitive reflection than a group given a placebo.
Nearly half of previously employed adult survivors of acute respiratory distress syndrome were jobless one year after hospital discharge, and are estimated to have lost an average of $27,000 in earnings, new research concludes.
Analysis of the drugs that were approved for use by the NHS Cancer Drugs Fund (CDF) in England has shown that the fund was not good value for patients and society and may have resulted in patients suffering unnecessarily from toxic side effects of the drugs.
A five-year study has found the mechanism responsible for repairing damage to mitochondrial DNA. This discovery could pave the way for new treatments for cancer and neurodegenerative diseases, say the researchers. This research may also have important implications for clinical advances in so called ‘three-parent baby’ mitochondrial donation.
Yersinia pestis, the bacterium that causes bubonic plague, can survive within the ubiquitous soil protozoan, the amoeba, by producing proteins that protect against the latter microbe's digestion, report scientists.
