Researchers have developed a new "clinicogenomic model" to accurately test for lung cancer. The model combines a specific gene expression for lung cancer as well as clinical risk factors.

Reshaping of the DNA scaffolding that supports and controls the expression of genes in the brain may play a major role in alcohol withdrawal symptoms, particularly anxiety, that makes it so difficult to stop using alcohol by alcoholics, researchers report in the Journal of Neuroscience.

Thanks to a new surgical technique used on Vasser's left knee called "cellular grafting," the 23-year-old is out cycling and refereeing soccer games on a virtually pain-free knee. The procedure was done for the first time on three young patients with steroid-induced osteonecrosis of the knee by a Stanford orthopedic surgeon.

Female vets run twice the risk of miscarriage as a result of exposure to anesthetic gases and pesticides, suggests a study in Occupational and Environmental Medicine.

Both short and long sleeping times predict an increased risk of future body weight and fat gain in adults. Short and long duration sleepers were 35 percent and 25 percent more likely to experience a 5 kg weight gain, respectively, as compared with average duration sleepers over six years. The risk of developing obesity was elevated for short and long duration sleepers as compared with average duration sleepers, with 27 percent and 21 percent increases in risk, respectively.

Surgeons and patients can now show that corneas from older donors are as successful for transplants after five years as is tissue from younger donors, allowing possible expansion of the donor pool.

Scientists have discovered a new technique for turning embryonic stem cells into insulin-producing pancreatic tissue in what could prove a significant breakthrough in the quest to find new treatments for diabetes.

Sleepwalkers are advised to keep a regular bedtime to avoid unwanted evening strolls, based on new research. In the study, patients were kept awake for the entire evening and remained under constant supervision. Recovery sleep was allowed the next morning after patients had been awake for 25 hours. The research team evaluated their behavior, which ranged from playing with bed sheets to trying to jump over the bed rails. Results were striking.

A diagnostic kit shows new promise for distinguishing between tuberculosis and its infections from disease caused by related mycobacteria family, which mimic TB and other lung disease in symptoms but require distinctly different clinical treatments.

Combining a breast cancer patient's clinical characteristics with a genomic profile of her tumor may provide important information for predicting an individual patient's prognosis and accurately guiding treatment options, according to a new study.
