Until now there were only indirect evidence of the transfer of thyroid hormones from mother to fetus through the placenta during pregnancy. That event is very important because the maternal thyroid hormones appear to play a key role in the development of the nervous system and other organs of the fetus; so it's true that in case of maternal thyroid disease, such hypothyroidism, have a direct bearing on the unborn child with reduction, also significant, to its Q.I.. That passage of maternal...

New findings by UT Southwestern Medical Center researchers suggest that the hormones leptin and insulin work together in specific neurons in the hypothalamus region of the brain to affect both the regulation of blood sugar levels in the body and, surprisingly, female fertility. "Many people, and even many physicians, think you develop diabetes that is solely secondary to obesity," said Dr. Joel Elmquist, professor of internal medicine and pharmacology at UT Southwestern and senior author of...

Bad behavior in childhood is associated with long-term, chronic widespread pain in adult life, according to the findings of a study following nearly 20,000 people from birth in 1958 to the present day. Chronic widespread pain is a common complaint that can have a major adverse effect on quality of life, often requiring referral to a hospital specialist for investigation and treatment. The research, published online in the journal Rheumatology today (Wednesday 10 March), found that children...

We all have at one time or another experienced the typical signs of an infection: the fever, the listlessness, the lack of appetite. They are orchestrated by the brain in response to circulating cytokines, the signaling molecules of the immune system. But just how cytokines' reach extends beyond the almost impenetrable blood-brain barrier has been the topic of much dispute. In their latest study, researchers at the Salk Institute for Biological Studies describe how, depending on the nature of...

Previous work in birds and sheep shows a wealth of clinical possibilities Nearly 10 years after the discovery that birds make a hormone that suppresses reproduction, University of California, Berkeley, neuroscientists have established that humans make it too, opening the door to development of a new class of contraceptive and possible treatments for cancer or other diseases. The hormone, gonadotropin inhibitory hormone (GnIH), has the opposite effect from gonadotropin releasing hormone, a key...

Persons with higher levels of leptin, a protein hormone produced by fat cells and involved in the regulation of appetite, may have an associated reduced incidence of Alzheimer disease and dementia, according to a study in the December 16 issue of JAMA. Previous studies have shown that overweight and obesity in mid-life are associated with poorer cognitive function in the general population and an increased risk of dementia. There has been evidence that leptin exerts additional functions on...

Even the anticipation of sweets may cause our muscles to start taking up more blood sugar, say researchers reporting in the December issue of Cell Metabolism, a Cell Press publication. That message is delivered via neurons in the brain's hypothalamus containing the chemical known as orexin and the sympathetic nervous system, the studies in mice and rats suggest. Orexin neurons are known to switch on when we are motivated to eat or seek other rewards. They also play a role in active...

Contrary to the prevailing view, the hormone leptin, which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain, according to a recent study published in Cell by Yale School of Medicine researchers and colleagues at Columbia University. This new finding contradicts the view that leptin acts primarily in the hypothalamus. "Our study challenges the view that the hypothalamus is the...

Leptin-serotonin pathway offers new clues for obesity and osteoporosis prevention New research from Columbia University Medical Center has illuminated a previously unknown leptin-serotonin pathway in the brain that simultaneously promotes appetite and bone mass accrual. The research, which explains how leptin "“ well-known appetite-suppressing hormone "“ acts in the brain, is published in the Sept. 4 issue of Cell. When the leptin-serotonin pathway is turned on in mice, the...

The weight-loss effect of leptin, a hormone produced by fat tissue, has been linked to higher levels of the brain chemical dopamine, U.S. researchers said. The animal studies, published in Cell Metabolism, found neurons with receptors for the hormone leptin exist in many parts of the brain -- not just the area controlling satiety. Martin Myers Jr. of the University of Michigan in Ann Arbor says rat studies suggest that in addition to the area controlling the feeling of fullness after eating,...

The hypothalamus is an organ that serves as an important link, along the hypothalamic-hypophyseal axis, between the nervous system and the endocrine system. It is located within the cranial cavity, in the cerebrum, right below the thalamus. It also forms the floor of the third ventricle in the brain. It contains neural pathways, blood vessels, glial cells, and secretory cells—all of which work together to control things like body temperature, hunger, thirst, sleep, and hormonal and...
