Hormone News and Research

RSS

A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

Men treated with hormone-based therapy for prostate cancer face higher risk of colorectal cancer: Study

Men treated with hormone-based therapy for prostate cancer faced a 30 percent to 40 percent higher risk of colorectal cancer, compared to patients who did not receive this treatment, according to a new study.

Food, drugs of abuse engage same brain systems, show studies

New animal research helps explain why some eat without hunger or to excess. The studies explore the biological effects of poor eating habits, showing that high-fat diets cause lasting brain changes that may impair healthy eating. Additional studies show that food and drugs of abuse engage many of the same brain systems. The findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.

Women and cancer today

Experts have warned that women who have their breasts removed out of fear of a high hereditary risk of breast cancer may be doing so needlessly. Genetic tests like for the BRCA mutations have predicted a high risk of getting breast cancer in women with many breast cancer sufferers among their first degree relatives. Earlier studies suggest the risk of the mutation to predict the cancer 87% of the time. Now experts want that this is an overestimate.

Women abused as kids at increased risk of developing diabetes: Study

The latest research shows that women who were victims of childhood abuse may be at increased risk of developing diabetes in adulthood. For the study the scientist team looked at 67,853 U.S. nurses in the Nurses Health Study II and found that 54 percent reported physical abuse and 34 percent reported sexual abuse before age 18. Moderate and severe physical and sexual abuse was associated with a 26 percent to 69 percent increased risk of type 2 diabetes in adulthood.

Novel mechanism regulating circadian rhythm identified

Scientists from the Florida campus of The Scripps Research Institute have identified for the first time a novel mechanism that regulates circadian rhythm, the master clock that controls the body's natural 24-hour physiological cycle. These new findings could provide a new target not only for jet lag, shift work, and sleep disturbances, but also for disorders that result from circadian rhythm disruption, including diabetes and obesity as well as some types of cancer.

Hormones and stress are major contributors to depression in women who undergo IVF

Between 20 and 30 percent of women who undergo in vitro fertilization (IVF) procedures suffer from significant symptoms of depression. Many practitioners believe that the hormone therapy involved in IVF procedures is primarily responsible for this. But new research from Tel Aviv University shows that, while this is true, other factors are even more influential.
