Study finds gender difference in brain function of schizophrenics

Schizophrenia is a mental disorder that differs between the sexes in terms of age at onset, symptomatology, response to medication, and structural brain abnormalities. Now, a new study from the Universit- de Montr-al shows that there is gender difference between men and women's mental ability with women performing better than men.

Scientists solve receptor structure that responds to neurotransmitter dopamine

A team led by scientists at The Scripps Research Institute has solved the structure of one of the receptors that responds to the neurotransmitter dopamine. Although dopamine transmission is essential to normal brain functioning, the biological assembly of the molecules involved in this crucial neuronal interplay had not been known until now.

Health literacy leads to less hospitalization for heart failure

Being able to read and understand words like anemia, hormones and seizure means a patient with heart failure may be less likely to be hospitalized, according to a new study from Emory University School of Medicine. Findings will be presented Nov. 17 at the American Heart Association Scientific Sessions conference in Chicago.

Dim light at night linked to depression

Exposure to even dim light at night is enough to cause physical changes in the brains of hamsters that may be associated with depression, a new study shows.

New anti-cancer drug targeting vitamin D receptor reduces PSA level in HRPC

A new anti-cancer drug aimed at vitamin D receptors on cancer cells has prompted encouraging responses in the levels of PSA (prostate specific antigen) in men with prostate cancer that has become resistant to hormonal therapies.

Neuralstem files NSI-189 IND with FDA for Phase I safety trials for major depression

Neuralstem, Inc. announced that it has filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (FDA) to begin two Phase I safety trials to test NSI-189, its first small molecule compound, for the treatment of major depression. NSI-189 is a proprietary new chemical entity discovered by Neuralstem that stimulates new neuron growth in the hippocampus, an area of the brain that is believed to be involved in depression.

New cellular pathway could help develop therapeutic treatments for obesity-related disorders

Cardiac researchers at the University of Cincinnati (UC) have found a new cellular pathway that could help in developing therapeutic treatments for obesity-related disorders, like diabetes and heart disease.

New layer of kidney cells can purify blood

Researchers at Eindhoven University of Technology (TU/e) and the University Medical Center Groningen have succeeded in culturing a layer of kidney cells in the lab. These cells maintained their functional properties, and are able to purify blood.

Noninvasive method to determine estrogen levels in infants through diapers

With the help of babies and more than 5,000 of their diapers, Emory University researchers have developed an accurate, noninvasive method to determine estrogen levels in infants.

Teenage binge drinking could cause mental health problems in adulthood: Study

Binge-drinking teenagers may be putting themselves at higher risk in adulthood for mood disorders such as anxiety and depression, Loyola University Health System researchers report.

RNA-based drugs may prevent premature birth: Research

Tiny molecules called microRNAs act together with hormones to control the onset of labor, raising the prospect that RNA-based drugs might be able to prevent premature labor, researchers at UT Southwestern Medical Center have discovered in a preclinical study.

Researchers find additional work of oxytocin hormone

New human research suggests the chemical oxytocin dubbed the "cuddle hormone" because of its importance in bonding between romantic partners and mothers and children also influences feelings of well-being and sensitivity to advertising.

Acute sleep deprivation increases inflammation: Research

People who sleep poorly or do not get enough sleep have higher levels of inflammation, a risk factor for heart disease and stroke, researchers have found.

Women and cancer today

Experts have warned that women who have their breasts removed out of fear of a high hereditary risk of breast cancer may be doing so needlessly. Genetic tests like for the BRCA mutations have predicted a high risk of getting breast cancer in women with many breast cancer sufferers among their first degree relatives. Earlier studies suggest the risk of the mutation to predict the cancer 87% of the time. Now experts want that this is an overestimate.

Women abused as kids at increased risk of developing diabetes: Study

The latest research shows that women who were victims of childhood abuse may be at increased risk of developing diabetes in adulthood. For the study the scientist team looked at 67,853 U.S. nurses in the Nurses Health Study II and found that 54 percent reported physical abuse and 34 percent reported sexual abuse before age 18. Moderate and severe physical and sexual abuse was associated with a 26 percent to 69 percent increased risk of type 2 diabetes in adulthood.

Novel mechanism regulating circadian rhythm identified

Scientists from the Florida campus of The Scripps Research Institute have identified for the first time a novel mechanism that regulates circadian rhythm, the master clock that controls the body's natural 24-hour physiological cycle. These new findings could provide a new target not only for jet lag, shift work, and sleep disturbances, but also for disorders that result from circadian rhythm disruption, including diabetes and obesity as well as some types of cancer.

Androgen deprivation therapy may increase fracture risk in older men with localized prostate cancer: Research

Research presented today at a national conference by a team of investigators at The Cancer Institute of New Jersey (CINJ), shows careful consideration should be given before initiating androgen deprivation therapy, a common treatment for older men with localized prostate cancer.

Hormones and stress are major contributors to depression in women who undergo IVF

Between 20 and 30 percent of women who undergo in vitro fertilization (IVF) procedures suffer from significant symptoms of depression. Many practitioners believe that the hormone therapy involved in IVF procedures is primarily responsible for this. But new research from Tel Aviv University shows that, while this is true, other factors are even more influential.

Study sheds light on difficulty of controlling blood pressure in patients with high aldosterone levels

A hormone already responsible for increasing blood pressure by prompting the kidneys to retain salt appears to moonlight as a major stimulator of the brain centers that control the vascular system and blood pressure.

MicroRNAs linked to failure of duct development in mammary glands

Max Planck researchers discover novel mechanism for vertebrate organ development. Hormones, growth factors and several proteins ensure that development occurs in the right way, at the right time. The components that cause breast development in mammals, for example, were thought to be largely known. However, as a team of scientists from Göttingen, Frankfurt and Hanover have now discovered, in the case of breast development, hormones and proteins do not account for the full story.
