Scientists discover specific neurons that promote reward-like behaviors, alcohol consumption

Fri, 12/13/2019 - 02:00
Scientists have known that a region of the brain called the central nucleus of the amygdala (CeA) plays a role in behaviors related to alcohol use and consumption in general. It's been less known which precise populations of brain cells and their projections to other brain regions mediate these behaviors.

Study shows unexpected mechanism for lipid acquisition by breast cancer cells

Fri, 12/13/2019 - 01:53
High-fat diets and obesity have been shown to increase the risk of breast cancer and worsen outcomes and prognosis of breast cancer patients. A team of researchers from Dartmouth and Dartmouth-Hitchcock Norris Cotton Cancer Center led by William Kinlaw III, MD, sought to understand how fat from the diet might influence breast cancer cells.

Out-of-pocket costs for out-of-network, non-emergency hospital care nearly doubled in five years

Fri, 12/13/2019 - 01:50
The out-of-pocket financial burden for insured working Americans is substantial and growing - especially when it comes to out-of-network, non-emergency hospital care, a new study has found.

Researchers examine p53-deficient colon cancer cells to identify how p53 impacts metabolic adaptation

Fri, 12/13/2019 - 01:37
Colon cancer cells deficient in p53, one of the most important control proteins in cell growth, activate a particular metabolic pathway to adapt to the lack of oxygen and nutrients inside the tumor. Statins, which are often prescribed to lower cholesterol, block this metabolic pathway and cause the cancer cells to die, as scientists from the German Cancer Research Center have now discovered.

Researchers aim to improve oral delivery of insulin for diabetes patients

Fri, 12/13/2019 - 01:34
Diabetes is a chronic disease that occurs when the pancreas does not produce enough insulin -- a hormone that regulates blood sugar-- or the body cannot effectively use the insulin it produces.
