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.

Direct-to-consumer ‘low-T’ medication advertising increases prescriptions but may not improve health

Direct-to-consumer advertising for drugs to treat testosterone deficiency -- or "low T" -- increases prescriptions to men for hormone-replacement therapies but may not improve their health, UC Davis physician Richard Kravitz said in an editorial published in the March 21 issue of the Journal of the American Medical Association.

Insulin resistance linked to more rapid decline in cognitive performance

A new Tel Aviv University study published in the Journal of Alzheimer's Disease finds that insulin resistance, caused in part by obesity and physical inactivity, is also linked to a more rapid decline in cognitive performance.

Vanderbilt study compares side effects, outcomes of prostate cancer treatments with active surveillance

Faced with the negative quality-of-life effects from surgery and radiation treatments for prostate cancer, low risk patients may instead want to consider active surveillance with their physician, according to a study released Tuesday by the Journal of the American Medical Association

Penn scientists discover method that appears to provide early warning of transplant rejection

Approximately 30,000 organ transplants occur in the United States each year. However, between 20 and 50 percent—depending on the organ type—of the transplanted organs fail within five years, most often because the recipient's immune system attacks, or "rejects," the donated organ.

Scientists identify molecules that may be key to drug resistance in estrogen-driven breast cancers

Three-quarters of all breast cancer tumors are driven by the hormone estrogen. These tumors are frequently treated with drugs to suppress estrogen receptor activity, but unfortunately, at least half of patients do not respond to these treatments, leaving them with drug-resistant tumors and few options.

Circadian misalignments may favor diabetes development

Like almost all light-sensitive living beings, human beings follow biological rhythms set on a period of about 24 hours.

Why don’t patients always discuss hyperglycemia with their doctor?

Hyperglycemia occurs when a patient has higher than normal blood sugar levels. If the levels are very high, consistently 13-14 or above, the patient will start to feel tired, thirsty and feel the urge to go to the toilet frequently to pass urine (micturition).

Yale study identifies racial and ethnic disparities in Oncotype DX testing for women with breast cancer

In a simple definition, cancer is a disease of the cells, which is caused by gene mutations. For a proportion of patients, including women with hormone receptor positive (HR+) breast cancer, gene expression profiling has a substantial impact on treatment decision-making by determining which patients might—or might not—respond to particular treatment options.

Tulane researcher aims to improve hormone replacement therapy for post-menopausal women

New research at the Tulane School of Medicine is looking at an estrogen receptor that could be a site for targeted hormone replacement therapy in post-menopausal women.

Study: Phthalate exposure during early pregnancy can alter hormone levels in developing fetuses

Exposure during early pregnancy to some phthalates—man-made chemicals commonly found in household plastics, food and personal care products—can have adverse impacts on developing fetuses, according to a new study led by Dr. Sheela Sathyanarayana, a pediatric environmental health specialist at Seattle Children's Research Institute and associate professor at the University of Washington.

Study provides new insights into biological mechanisms underpinning type 2 diabetes pathology

It has been estimated that the number of people with diabetes worldwide reached 422 million in 2014, boosting prevalence to 8.5% among adults over 18 years of age. This figure is expected to rise to 642 million people by 2040.

Whole-body vibration can mimic muscle, bone health benefits of regular exercise in mice

A less strenuous form of exercise known as whole-body vibration can mimic the muscle and bone health benefits of regular exercise in mice, according to a new study published in the Endocrine Society's journal Endocrinology.

Type 2 diabetes can be reversed with intensive medical treatment, study shows

Type 2 diabetes can be reversed with intensive medical treatment using oral medications, insulin and lifestyle therapies, according to a study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

Women experience higher stress from major life events than men, study reveals

New research has highlighted the potential gender gap in stress, with women reporting higher stress from life events such as death of a loved one, illness, losing their smartphone and Brexit.

LCSB researchers identify how the body influences differentiation of progenitor cells

Stem cells are unspecialised cells that can develop into any type of cell in the human body. So far, however, scientists only partially understand how the body controls the fate of these all-rounders, and what factors decide whether a stem cell will differentiate, for example, into a blood, liver or nerve cell.

Study: Common drug used to prevent preterm births provides no benefit but may cause side effects

A drug commonly prescribed to pregnant women with a history of delivering babies early provides no benefit. In fact, this drug may even increase the risk of developing gestational diabetes.

Low levels of allopregnanolone hormone may predict risk of postpartum depression

In a small-scale study of women with previously diagnosed mood disorders, Johns Hopkins researchers report that lower levels of the hormone allopregnanolone in the second trimester of pregnancy were associated with an increased chance of developing postpartum depression in women already known to be at risk for the disorder.

Exposure to EDCs alters thyroid hormone signalling, early brain development in frog embryos

Findings published today provide evidence that exposure to endocrine disrupting chemicals (EDCs) causes changes in thyroid hormone signalling, which disturbs brain development.

Survey finds that most military physicians did not receive any formal training on transgender care

A small survey of military physicians found most did not receive any formal training on transgender care, most had not treated a patient with known gender dysphoria, and most had not received sufficient training to prescribe cross-hormone therapy, according to a new research letter published online by JAMA Internal Medicine.

Novel androgens play major role in development of PCOS, research shows

Scientists led by the University of Birmingham have discovered that a new class of male sex hormones known as androgens plays a key role in the development of polycystic ovary syndrome (PCOS).
