A new brain-imaging study by researchers at the Montreal Neurological Institute, McGill University reveals that ghrelin - a stomach hormone, acts on specific regions of the brain to enhance our response to food related cues and eating for pleasure. This study, published in the May 7 issue of Cell Metabolism, is critical to advance understanding and treating obesity, a condition affecting millions world-wide.

A common weedkiller in the U.S., already suspected of causing sexual abnormalities in frogs and fish, has now been found to alter hormonal signaling in human cells, scientists from the University of California San Francisco (UCSF) report.

A gut hormone that causes people to eat more does so by making food appear more desirable, suggests a new report in the May issue of Cell Metabolism, a publication of Cell Press. In a brain imaging study of individuals, the researchers found that reward centers respond more strongly to pictures of food in subjects who had received an infusion of the hormone known as ghrelin.

New Analysis by Applied Data Research Examines Clinical Developments and Assesses Healthcare Impact

Tests on the influence that a stress-related hormone has on learning in ground squirrels could have an impact on understanding how it influences human learning, according to a University of Chicago researcher.

Researchers found out that the level of sex hormones in the blood has no connection with the risk of prostate cancer.

Hormonal components in over-the-counter dietary supplements may promote the progression of prostate cancer and decrease the effectiveness of anti-cancer drugs, researchers at UT Southwestern Medical Center have discovered.

A hormone secreted by cells throughout the body and known to play a role in cardiovascular disease and other cell functions is also critical for proper formation of the lymphatic system in mice, according to research from the University of North Carolina at Chapel Hill School of Medicine.

Countless movies and TV shows make light of women’s so-called “moodiness”, often jokingly attributing it to their menstrual cycle or, conversely, to menopause. In fact, mood disorders are a serious and pervasive health problem, and large-scale population studies have found women are 1.5 to 3 times more likely to suffer from major depressive disorder than are men.

Growth hormone treatments work better on some children than on others, but judging which candidates will gain those vital inches in height is no simple task. Now researchers have developed a new mathematical model which predicts the optimal dose of growth hormone to treat children who are abnormally short for a wide range of reasons.

A new UC Davis study shows that a common antibacterial chemical added to bath soaps can alter hormonal activity in rats and in human cells in the laboratory—and does so by a previously unreported mechanism.

While investigating how the hormone orexin might control sleep and hunger, researchers at UT Southwestern Medical Center have discovered, to their surprise, that it activates a protein, HIF-1, long known to stimulate cancerous tumor growth.
