Increased levels of stress hormones in mother can affect foetal development

Increased levels of stress hormones can lead pregnant mice to overeat, but affect growth of the foetus and, potentially, the long term health of her offspring, according to a study published today.

Large numbers of boys suffer from cognitive disabilities linked to lead than girls

A study recently published in the Journal of Environmental Health provides evidence the female hormones estrogen and estradiol may help ward off the effects of lead exposure for young girls, explaining why boys, in greater numbers than girls, are shown to suffer from the cognitive disabilities linked to lead.

Study shows how gut bacteria can affect normal brain activity

The hundred trillion bacteria living in an adult human--mostly in the intestines, making up the gut microbiome--have a significant impact on behavior and brain health. The many ways gut bacteria can impact normal brain activity and development, affect sleep and stress responses, play a role in a variety of diseases, and be modified through diet for therapeutic use are described in a comprehensive Review article in Journal of Medicinal Food, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Thyroid disease can affect woman's reproductive health

Thyroid disease can have significant effects on a woman's reproductive health and screening for women presenting with fertility problems and recurrent early pregnancy loss should be considered, suggests a new review published today (23 January) in The Obstetrician & Gynaecologist.

Taking hormonal contraceptives for five years doubles brain tumour risk

Taking a hormonal contraceptive for at least five years is associated with a possible increase in a young woman's risk of developing a rare tumour, glioma of the brain. This project focussed on women aged 15 -49 years and the findings are published in the British Journal of Clinical Pharmacology.

Study: Prostate cancer drug stabilizes memory loss for a year in women with Alzheimer's disease

Women with Alzheimer's disease showed stable cognition for a year when a drug that is more commonly used to treat advanced prostate cancer was added to their drug regimen, according to a new study from researchers at the University of Wisconsin-Madison.

Long years of diabetes research now ripe for reinterpretation

Years of diabetes research carried out on mice whose DNA had been altered with a human growth hormone gene is now ripe for reinterpretation after a new study by researchers at KU Leuven confirms that the gene had an unintended effect on the mice's insulin production, a key variable in diabetes research.

Study suggests link between neonatal ghrelin and obesity risk

Our subconscious motivation to eat is powerfully and dynamically regulated by hormone signals. The gut-derived hormone ghrelin is one such key regulator, promoting appetite through its effects on neurons in a small region of the brain called the hypothalamus.

GSU researchers discover how steroids use a novel 'trick' to suppress inflammation

A new "trick" steroids use to suppress inflammation, which could be used to make new anti-inflammatory drugs without the harmful side effects of steroids, has been discovered by researchers at Georgia State University.

Research findings may lead to new treatment for hypothyroidism

An international research team led by physician-scientists at Rush University Medical Center have gained new insights into hypothyroidism - a condition affecting about 10 million people in the U.S. - that may lead to new treatment protocols for the disease, particularly among the approximately 15 percent of patients for whom standard treatments are less effective.

Knocking down a single gene can help stop stress from causing infertility, miscarriage

Scientists from the University of California Berkeley have discovered that by knocking down a single gene, they can stop stress from causing female infertility and miscarriage - in rats.

Scientists find that blocking hormone reduces stress-induced infertility in female rats

University of California, Berkeley, scientists have discovered that chronic stress activates a hormone that reduces fertility long after the stress has ended, and that blocking this hormone returns female reproductive behavior to normal.

Personal gender identity of every human being is reflected in the structure of brain networks

Our sense of belonging to the male or female gender is an inherent component of the human identity perception. As a general rule, gender identity and physical sex coincide. If this is not the case, one refers to trans-identity or transsexuality. In a current study, brain researcher Georg S. Kanz of the University Clinic for Psychiatry and Psychotherapy of the MedUni Vienna was able to demonstrate that the very personal gender identity of every human being is reflected and verifiable in the cross-links between brain regions.

Adding radiation treatment to hormone therapy saves older men with prostate cancer

Adding radiation treatment to hormone therapy saves more lives among older men with locally advanced prostate therapy than hormone therapy alone, according to a new study in the Journal of Clinical Oncology this week from Penn Medicine researchers.

New study shows that menstrual cycle may have an effect on nicotine cravings

The menstrual cycle appears to have an effect on nicotine cravings, according to a new study by Adrianna Mendrek of the University of Montreal and its affiliated Institut universitaire en santé mentale de Montréal.

Two hormones better than one for hypoglycaemia prevention with artificial pancreas

Artificial pancreas systems significantly improve glycaemic control in adolescents and adults with Type 1 diabetes, shows a head-to-head trial of single- and dual-hormone systems versus a conventional insulin pump.

Even men undergo hormonal changes on way to fatherhood, study finds

Impending fatherhood can lower two hormones--testosterone and estradiol--for men, even before their babies are born, a new University of Michigan study found.

Sensitive toxicity test aims to detect dangerous side effects in pharmaceutical development

Because of undetected toxicity problems, about a third of prescription drugs approved in the U.S. are withdrawn from the market or require added warning labels limiting their use. An exceptionally sensitive toxicity test invented at the University of Utah could make it possible to uncover more of these dangerous side effects early in pharmaceutical development so that fewer patients are given unsafe drugs.

Three studies reveal effects of blocking androgen receptors in breast cancer

Three studies presented by University of Colorado Cancer Center researchers at the San Antonio Breast Cancer Symposium 2014 demonstrate the effects of blocking androgen receptors in breast cancer.

Male hormone testosterone may increase risk of colon cancer

Previous cancer research has revealed that women are less likely than men to suffer from non-sex specific cancers such as cancer of the colon, pancreas and stomach. Scientists theorized that perhaps this trend was due to a protecting effect created by female hormones, such as estrogen, that help prevent tumors from forming. Now, researchers at the University of Missouri have found evidence suggesting that the male hormone testosterone may actually be a contributing factor in the formation of colon cancer tumors.
