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.

Experts discuss link between breast milk components, circadian variation, and infant health

The fat content and levels of several key nutrients and hormones in breast milk vary with the mother's circadian rhythm, which may have implications for the timing of breastfeeding and feeding of expressed milk, especially for high-risk infants.

Research deepens understanding of interconnection between nervous and immune system

A newly-discovered reflex arc mediates a process which leads to a disruption in the hormones secreted by the adrenal glands which, in turn, results in an increased susceptibility to bacterial infections.

Epidemiologist to advance research on hormonal markers for better prediction of breast cancer risk

Epidemiologist Susan Hankinson at the University of Massachusetts Amherst has received a five-year, $4.2 million grant from the National Cancer Institute to build upon and advance her research group's earlier work to identify and validate hormonal markers to better predict the risk of invasive breast cancer in postmenopausal women.

Lower-than-normal TSH levels linked to increased risk of thyroid cancer

There is an increased risk of thyroid cancer associated with lower-than-normal thyroid hormone levels, a finding that could have a major impact on patients fighting the disease.

Researchers precisely describe effects of frequent genetic mutation in congenital hyperinsulinism

Diabetes is characterized by a deficiency of insulin. The opposite is the case in congenital hyperinsulinism: patients produce the hormone too frequently and in excessive quantities, even if they haven't eaten any carbohydrates.

Link between breast cancer and obesity may be more complex than previously thought

Obese women with large bellies may be at risk of developing a different subtype of breast cancer than those with widespread fat accumulation, according to a new study published in The Oncologist. This suggests that the link between breast cancer and obesity may be more complex than previously thought.

Research unravels how stem cells in the ovaries may be harnessed to revolutionize fertility treatments

About 13 years ago, Northeastern professor Jonathan Tilly, a reproductive biologist, made a discovery that challenged everything scientists thought they knew about female reproduction. The long-held belief that mammals were born with a set number of eggs -- and no ability to create new ones -- was wrong.

Hormone therapy for menopausal symptoms does not increase mortality risk, according to a long-term study

An 18-year follow-up study of postmenopausal women in the Women’s Health Initiative trials has shown that the use of hormone therapy was not associated with any increased risk of all-cause, cardiovascular or cancer death.

Study uncovers how inflammation contributes to key feature of diabetes

A new study by researchers at the University of Maryland School of Medicine has uncovered how inflammation contributes to a key feature of diabetes, the body's inability to metabolize glucose, a condition known as insulin resistance.

Phthalate levels in expectant fathers influence sperm epigenetics, study suggests

Early results from a larger, ongoing study led by environmental health scientist Richard Pilsner at the University of Massachusetts Amherst suggest that phthalate levels in expectant fathers have an effect on couples' reproductive success via epigenetic modifications of sperm DNA.

Most patients treated for atrial fibrillation have sleep apnea, study shows

A study involving cardiac patients at the University Hospital of Umeå shows that over 80 percent of patients treated for atrial fibrillation also have sleep apnea - a condition with pauses in breathing during sleep.

Abdominal weight found to be key predictor of cancer risk in postmenopausal women

Body fat distribution in the trunk is more important than body weight when it comes to cancer risk in postmenopausal women, according to a study presented at the ESMO 2017 Congress in Madrid.

Regulatory T-cells can support fat depots in dealing with environmental challenges

Immunosuppressive regulatory T-cells play an important role in the functioning of adipose tissue. This is the discovery of scientists from the Helmholtz Diabetes Center at Helmholtz Zentrum München and the Technical University of Munich.

AI used to detect sexual orientation from facial images

New research has used a novel technology to successfully determine the sexual orientation of people from facial images or photographs. The accuracy of these techniques is reportedly more than those detected by humans. The study details are to be published n the Journal of Personality and Social Psychology. At present the study is available in a draft form.

Bariatric surgery in men linked to frequent sperm aberrations and lower fertility rates

A meta-analysis of studies in which men underwent Roux-en-Y gastric bypass (RYGB) procedures found frequent sperm aberrations and lower fertility rates despite improvements in weight, androgen levels, and sexual quality of life following the procedure.
