Food addicts appear to have high neural activity in brain

Persons with an addictive-like eating behavior appear to have greater neural activity in certain regions of the brain similar to substance dependence, including elevated activation in reward circuitry in response to food cues, according to a report posted online today that will appear in the August print issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Injection of stem cells may improve effectiveness of cardiac bypass surgery

In a new research study under way at the Methodist DeBakey Heart & Vascular Center, surgeons are adding a patient's own stem cells to the heart during cardiac bypass surgery. The goal of this research study is to determine whether the stem cell infusion will generate new blood vessels and improve heart function more than what is seen through bypass surgery alone.

Vitamin D can reduce estrogen receptor-positive breast cancer

In mice models of breast cancer, researchers at the Georgetown Lombardi Comprehensive Cancer Center, a part of Georgetown University Medical Center, found that vitamin D significantly reduced development of estrogen receptor-positive breast cancer both in lean and obese mice, but had no beneficial effect in estrogen receptor-negative cancer.

New anti-angiogenic therapy can lead to tumour growth inhibition

Scientists from the School of Pharmacy at Queen's University Belfast and Almac Discovery Ltd, announce the first publication describing a potential new anti-angiogenic therapy based on a natural protein first discovered at QUB. Anti-angiogenics prevent the growth of new blood vessels in tumours and starve them of nutrients, leading to inhibition of tumour growth.
