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.

Chances of survival due to chemotherapy significantly lower for older breast cancer patients

Chemotherapy prolongs life for older adults with most types of cancer, but for women over the age of 80 with breast cancer, the chances of survival due to chemotherapy are significantly lower, according to a study led by researchers from The University of Texas Health Science Center at Houston.

New research could help develop precision medicine for primary aldosteronism

Each of your kidneys wears a little yellow cap that helps keep your blood pressure in check, and much more. But in some people, it starts running amok, pumping out a hormone that sends blood pressure sky-high.

Postmenopausal women more likely to use vaginal estrogen to achieve significantly higher sexual quality of life

Local vaginal estrogen (VE) appears to have escaped the shroud of doubt cast upon hormone therapy as a result of the Women's Health Initiative Study by providing numerous medical benefits without systemic effects. That's according to a new study reported online today in Menopause, the journal of The North American Menopause Society.

Retrieving eggs at earlier stage of fertility treatment may improve pregnancy rates for older women

IVF success rates for women aged 43 and above could improve by retrieving eggs from their ovaries at an earlier stage of fertility treatment, according to a new study published today in the Journal of Endocrinology.

Researchers elucidate mechanism that induces skeletal muscle atrophy in patients with congestive heart failure

It is a paradox: Patients with advanced congestive heart failure lose skeletal muscle mass, but their heart muscles become enlarged to provide the body with an adequate supply of blood and thus with oxygen. It has long been known that the protein angiotensin II plays a villainous role in this process, but the exact mechanism has remained unclear.

TEAAM trial finds that testosterone has no effect on atherosclerosis progression

Testosterone sales have grown rapidly over the last decade, but few studies have examined the long-term effects of taking testosterone on cardiovascular health and other important outcomes. This week, investigators from Brigham and Women's Hospital report the results of the Testosterone's Effects on Atherosclerosis Progression in Aging Men (TEAAM) trial in the Journal of the American Medical Association.

Education intervention can improve physicians’ understanding of transgender issues

The term "transgender" has made its way into mainstream media thanks to Caitlyn Jenner, previously known as Bruce Jenner, who came out as a transgender woman earlier this year.

TSRI study shows antioxidants slow aging process, reduce risk of infection

Scientists from the Florida campus of The Scripps Research Institute have shown how aging cripples the production of new immune cells, decreasing the immune system’s response to vaccines and putting the elderly at risk of infection.

Clinical study shows two-drug combination can prolong survival in men with metastatic prostate cancer

Newly diagnosed patients with metastatic, hormone-sensitive prostate cancer gained a dramatic survival benefit when started on two drugs simultaneously, rather than delaying the second drug until the cancer began to worsen, according to results of a clinical trial led by a Dana-Farber Cancer Institute scientist.

Oral contraceptives give long-term protection against endometrial cancer, shows study

Use of oral contraceptives, even for just a few years, gives substantial long-term protection against endometrial cancer, and the longer the pill is used the greater the reduction in risk, according to a detailed re-analysis of all the available evidence, published in The Lancet Oncology journal.

Swedish study reveals combined effects of smoking and early menopause on overall mortality

Women may now have yet another reason to quit smoking given the results of a new study that is being reported online today in Menopause, the journal of The North American Menopause Society. The Swedish study involving 25,474 women is the first to quantify the combined effects of smoking and age at menopause on overall mortality in terms of survival time by investigating the role of smoking as a possible effect modifier.

Researchers reveal how insulin reaches and acts in the brain to improve memory

Researchers at the UW Medicine, Veteran's Administration Puget Sound and Saint Louis University have made a promising discovery that insulin delivered high up in the nasal cavity goes to affected areas of brain with lasting results in improving memory.

Research: Critical aspects of human genome's regulatory program encoded by genomic sequence elements

Since the classical studies of Jacob and Monod in the early 1960s, it has been evident that genome sequences contain not only blueprints for genes and the proteins that they encode, but also the instructions for a coordinated regulatory program that governs when, where and to what extent these genes and proteins are expressed.

Researchers explore key factors to improve astronauts’ nutrition needs during space missions

Centuries ago, ships often sailed with crews numbering in the hundreds returning with tens. Cause of death: Scurvy - a severe depletion of Vitamin C.

Atomic level images reveal how neuropeptide hormone neurotensin may activate its receptors

Many hormones and neurotransmitters work by binding to receptors on a cell's exterior surface. This activates receptors causing them to twist, turn and spark chemical reactions inside cells.

Study sheds light on certain antagonist drugs that block physiological responses

Members of the Consolidated Research Group of Molecular Neurobiology of the Department of Biochemistry and Molecular Biology of the University of Barcelona (UB), affiliated with the Centre for Networked Biomedical Research on Neurodegenerative Diseases (CIBERNED), have published a study in the journal Proceedings of the National Academy of Sciences (PNAS) about the formation of G protein-coupled receptors (GPCRs) which allows understanding the unexpected behaviour of some antagonists that block physiological responses.

New research shows promising progress in use of anti-inflammatory cytokine for T1D treatment

New research from Uppsala University shows promising progress in the use of anti-inflammatory cytokine for treatment of type 1 diabetes. The study, published in the open access journal Scientific Reports (Nature Publishing Group), reveals that administration of interleukin-35 (a protein made by immune cells) to mice with type 1 diabetes, reverses or cures the disease by maintaining a normal blood glucose level and the immune tolerance.

Endocrine Society recommends removal of tumor as first-line treatment for endogenous Cushing's syndrome

The Endocrine Society today issued a Clinical Practice Guideline (CPG) on strategies for treating Cushing's syndrome, a condition caused by overexposure to the hormone cortisol.

LixiLan-O Phase III clinical trial meets primary endpoint in patients with type 2 diabetes

Sanofi announced today that the LixiLan-O Phase III clinical trial met its primary objective in patients with type 2 diabetes treated with metformin. The fixed-ratio combination of insulin glargine 100 units/mL and lixisenatide, a GLP-1 RA, demonstrated statistically superior reduction in HbA1c (average blood glucose over the previous three months) compared with lixisenatide and compared with insulin glargine 100 units/mL.
