Hormone found naturally in the body has the ability to cause limited weight loss

Research at the Oregon National Primate Research Center (ONPRC) at Oregon Health & Science University has demonstrated that a hormone found naturally in the body has the ability to cause limited weight loss. Specifically, the research revealed that peptide YY (PYY) can reduce food consumption in the morning, leading to a mild level of weight loss in the short term.

Early detection and improved treatment have contributed almost equally to the substantial decrease in breast cancer

Early detection through screening mammography and improved adjuvant treatment have contributed almost equally to the substantial decrease in breast cancer death rates over the past 10 to 15 years, researchers conclude in an unprecedented effort to parse out the factors that have led to the decline.

Growth hormone illegal for off-label anti-aging use

Because of 1988 and 1990 amendments to the Food, Drug and Cosmetic Act, off-label distribution or provision of human growth hormone to treat aging or age-associated illnesses is illegal in the United States, according to a report in the Journal of the American Medical Association.

The face represents an important window into the influences of stress and emotion on health

A provocative new study has found that people who respond to stressful situations with angry facial expressions, rather than fearful expressions, are less likely to suffer such ill effects of stress as high blood pressure and high stress hormone secretion.

Women on breast cancer treatment opt for injections to curb hot flashes

Apparently, given a choice, many breast cancer patients using hormone therapies such as Tamoxifen to cut the risk of recurrence, would opt for pills rather than injections.

Testosterone may improve women's sex lives after menopause

The addition of testosterone to hormone therapy in women after menopause enhances their sexual function. However, it may also reduce HDL cholesterol (the "good" cholesterol) in women, according to a systematic review of current evidence.

Diabetes drugs may also prevent nerve degeneration caused by Alzheimer's disease

Recent research has shown a surprising link between Alzheimer’s and diabetes, two of the major health challenges facing society today. According to Dr Holscher modern lifestyle promotes the development of type 2 diabetes, which in turn could drastically increase the number of people to develop Alzheimer’s disease as people with type 2 diabetes are much more likely to develop the disease than healthy people of the same age.

IVF gives women false expectations

Experts are warning that women are risking their chances of having children because they are delaying motherhood on the basis of "false expectations" about the success of IVF treatment.

Distress caused by hot flushes seriously under-played

A study by UK researchers of over 200 breast cancer patients receiving hormone treatments such as tamoxifen has found that nearly two-thirds would prefer to take a tablet daily and around a quarter would prefer a monthly injection, given that both treatments would be equally effective and have similar side-effects.

Blocking macrophage migration inhibitory factor molecule might prevent the progression of multiple sclerosis

A new study suggests that a substance made by immune cells plays a key role in the progression of a disease in animals that closely mimics multiple sclerosis (MS). The findings further suggest that blocking the molecule, known as macrophage migration inhibitory factor (MIF) might prevent the progression of the disease.
