Protecting genes, one molecule at a time

An international team of scientists has shown at an unprecedented level of detail how cells prioritize the repair of genes containing potentially dangerous damage. Cells use proteins to detect and replace damaged DNA, with critical steps at individual protein reads likely critical for successful repair.

Wolf mange part of nature's cycle

Researchers tracked parasite-induced disease and death in reintroduced wolf packs in Yellowstone National Park, finding that mange did not infect wolves until 2007. The diseases that infected the wolves quickly were all viral, including canine distemper and parvovirus, while mange is a skin infection caused by scabies mites.

Antibiotic therapy improves moderate exacerbations of mild-to-moderate COPD

A multicenter trial found that antibiotic treatment with amoxicillin/clavulanate significantly improved clinical cure rates and prolonged the median time to next exacerbation in patients with mild-to-moderate COPD. Patients with elevated capillary C-reactive protein (CRP) levels were more likely to be cured without antibiotics.

Blood sugar control does not help infants and children undergoing heart surgery

A recent study funded by the NIH found that tight glycemic control in pediatric cardiac surgery patients did not reduce healthcare-related infections, organ failure, or death. The study's findings diverge from previous studies on adult intensive care unit (ICU) patients who showed benefits from blood sugar control.

Employees at 'green' companies are significantly more productive, study finds

A new UCLA-led study found that employees in green companies, which adopt international environmental standards, are 16 percent more productive than the average. The researchers discovered a positive correlation between the adoption of these practices and increased employee motivation, training, and interpersonal relationships.

Strategy developed to improve delivery of medicines to the brain

Scientists at NIEHS discover a way to turn off P-glycoprotein, a major gatekeeper preventing medicinal drugs from reaching the brain, allowing small therapeutic agents to cross the blood-brain barrier. This breakthrough could lead to new treatments for central nervous system diseases such as brain and spinal cord injury, brain cancer, ...

Tight glycemic control has no proven benefits for children in the cardiac ICU

A new study conducted at Boston Children's Hospital found that tight blood sugar control does not benefit pediatric patients undergoing heart surgery. The Safe Pediatric Euglycemia in Cardiac Surgery (SPECS) trial examined the effects of insulin on glucose management and showed no impact on infection rates, length of stay, or mortality.
