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.

Protein-restricted diet supplemented with IGF-I may protect from Alzheimer's

Mice with many of the pathologies of Alzheimer's Disease showed fewer signs of the disease when given a protein-restricted diet supplemented with specific amino acids every other week for four months.

Study determines effectiveness of sewage lagoons at removing pharmaceuticals from wastewater

2012 marked the 40th anniversary of the Clean Water Act, which established regulations for the discharge of pollutants to waterways and supported the building of sewage treatment plants. Despite these advances, sewage remains a major source of pharmaceuticals and personal care products (PPCPs) and naturally occurring hormones found in the environment.

Nucleic Acid Therapeutics publishes special research section on noncoding RNAs

As scientists continue to unravel the complexity of the human genome and to uncover vital elements that play a role in both normal physiology and disease, one particular class of elements called noncoding RNAs is gaining a lot of attention. Guest Editor Tom Cech, PhD and Executive Editor Fintan Steele, PhD explore the enormous potential value of this rapidly advancing research area in their Editorial " The (Noncoding) RNA World."

DNA repair mechanisms tied to reproductive aging

Age-related decline in the efficacy of DNA repair may underlie reproductive aging, say researchers.

Blood’s tendency to clot may contribute to white matter hyperintensities in post-menopausal women

New Mayo Clinic research suggests that blood may hold clues to whether post-menopausal women may be at an increased risk for areas of brain damage that can lead to memory problems and possibly increased risk of stroke. The study shows that blood's tendency to clot may contribute to areas of brain damage called white matter hyperintensities.

Early detection, treatment needed to reduce risk of death and CVD in older Cushing's disease patients

Even after successful treatment, patients with Cushing's disease who were older when diagnosed or had prolonged exposure to excess cortisol face a greater risk of dying or developing cardiovascular disease, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

High anti-M-llerian hormone levels signal increased likelihood of pregnancy, birth

Women with a high concentration of anti-M-llerian hormone stand a better chance of giving birth after in vitro fertilization, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

GSK, Vanderbilt partner to develop and commercialize new therapies for severe obesity

Vanderbilt University announced today that it has signed a collaboration agreement with GlaxoSmithKline (GSK) for the discovery, development and commercialization of novel therapies for severe obesity.

Tips for menopausal women to better enjoy their sex lives

Menopause can be a real rollercoaster—and that can impact women's sex lives. It can cause women's libidos to climb, suddenly drop, and then climb again due to the combination of estrogen and women's own levels of testosterone powering this wild cycle.

Low vitamin D not linked to poor physical performance in octogenarians

Researchers have found no evidence for a link between low vitamin D levels and impaired physical performance in people aged 80 years or older.

Two different mechanisms trigger early-onset prostate cancers

While prostate cancer is the most common cancer in elderly Western men it also, but more rarely, strikes patients aged between 35 and 50. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, in collaboration with several other research teams in Germany, have discovered that such early-onset prostate cancers are triggered by a different mechanism from that which causes the disease at a later age.

MicroRNA can be used to define four subtypes of triple-negative breast cancer

A new, large-scale study of triple-negative breast cancer shows that small molecules called microRNA can be used to define four subtypes of this aggressive malignancy.

Long-acting reversible contraception with progestin may increase risk of type 2 diabetes in women

A first-of-its-kind study by researchers at the Keck School of Medicine of the University of Southern California (USC) indicates that healthy, obese, reproductive-age women who use long-acting reversible contraception (LARC) containing the hormone progestin have a slightly increased risk for developing type 2 diabetes when compared to those who use non-hormonal contraception.

Northwestern Medicine expert offers tips to battle seasonal affective disorder

Winter is in full force. With short days and less exposure to sunlight, everyone feels less energetic and more people are vulnerable to depression. Seasonal Affective Disorder (SAD), or winter depression, is a mood disorder related to seasonal variations of light. Symptoms start in late fall and oftentimes last until April or early spring. It affects between 10 to 20 percent of Americans, primarily younger adults and women.

Combination of two antibodies prevents growth and spread of triple-negative breast tumors

Cancer drugs of the new, molecular generation destroy malignant breast tumors in a targeted manner: They block characteristic molecules on tumor cells - receptors for the hormones estrogen or progesterone, or a co-receptor, called HER2, that binds to many growth factors. But about one in every six breast tumors has none of these receptors. Such cancers, called triple-negative, are particularly aggressive and notoriously difficult to treat.

Researchers design guideline for physicians and patients on Androgen Insensitivity Syndrome

University of Granada researchers have designed a guideline for physicians and patients on the Androgen Insensitivity Syndrome (AIS), a rare disease that makes the subject develop reverse sex, which occurs when a subject looks like a woman but has male genes.

Tumor suppressor mutant may predict poor outcome in breast cancer

An oncogenic variant of the Krüppel-like family 6 tumor suppressor gene appears to play a role in driving breast cancer metastasis and may be a prognostic marker for poor patient outcome, report researchers.

Investigators use genome analysis to eliminate lifetime drug prescription in two children

Using genome-wide analysis, investigators at the Sainte-Justine University Hospital Research Center and the University of Montreal have potentially eliminated a lifetime drug prescription that two children with a previously unknown type of adrenal insufficiency had been receiving for 14 years.

Identification of progenitors may help treat clinical taste dysfunction

Scientists at the Monell Center have identified the location and certain genetic characteristics of taste stem cells on the tongue. The findings will facilitate techniques to grow and manipulate new functional taste cells for both clinical and research purposes.
