Scientists unveil mechanism of liver regeneration

The liver's unique ability among organs to regenerate itself has been little understood. Now Weill Cornell Medical College scientists have shed light on how the liver restores itself by demonstrating that endothelial cells the cells that form the lining of blood vessels play a key role.

Scientists create functional neurons to study ASD development

Using induced pluripotent stem cells from patients with Rett syndrome, scientists at the University of California, San Diego School of Medicine have created functional neurons that provide the first human cellular model for studying the development of autism spectrum disorder (ASD) and could be used as a tool for drug screening, diagnosis and personalized treatment.

Research on fruit flies reveal novel human pain gene

While it has become clear in recent years that susceptibility to pain has a strong inherited component, very little is known about actual "pain genes" and how they work. In the November 12th issue of Cell, researchers at Children's Hospital Boston and their collaborators report on a novel human pain gene. People with minor variations in this gene showed clear differences in susceptibility to acute heat pain and chronic back pain.

Research unveils epigenetic function of MECP2 gene tht cause neuropsychiatric disorders

The laboratory of Huda Zoghbi, where the discovery that mutations in the gene MECP2 cause the severe childhood neurological disorder Rett Syndrome was made, has taken yet another step toward unraveling the complex epigenetic functions of this gene, implicated also in cases of autism, bipolar disease and childhood onset schizophrenia. The November 11 issue of Nature reports that removing MECP2 from a small group of neurons that typically make the inhibitory neurotransmitter, GABA, recapitulates many symptoms of Rett as well as numerous neuropsychiatric disorders.

Elevated levels of MCP-1 found in urine of patients with acute kidney injury

The presence of certain markers in the urine might be a red flag for acute kidney injury (AKI), according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). The results suggest that a simple urine test could help prevent cases of kidney failure.

MU researchers find 70% of Amazonian cultures practiced multiple paternity

In modern culture, it is not considered socially acceptable for married people to have extramarital sexual partners. However, in some Amazonian cultures, extramarital sexual affairs were common, and people believed that when a woman became pregnant, each of her sexual partners would be considered part-biological father. Now, a new University of Missouri study published in the journal Proceedings of the National Academy of Sciences has found that up to 70 percent of Amazonian cultures may have believed in the principle of multiple paternity.

Neuron subtypes control level of fear output from amygdala

The eerie music in the movie theater swells; the roller coaster crests and begins its descent; something goes bump in the night. Suddenly, you're scared: your heart thumps, your stomach clenches, your throat tightens, your muscles freeze you in place. But fear doesn't come from your heart, your stomach, your throat, or your muscles. Fear begins in your brain, and it is there specifically in an almond shaped structure called the amygdala that it is controlled, processed, and let out of the gate to kick off the rest of the fear response.

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.

German Genetic Diagnostics Act in need of amendment

Many aspects of the German Genetic Diagnostics Act (Gendiagnostikgesetz) are out of touch with the latest technology, almost impossible to implement in clinical practice, or even detrimental to the success of recognised screening tests, such as newborn screening. The Act, which came into force in February 2010, is in desperate need of amendment.

Researcher finds new way to analyze biopsies from heart transplant patients

Michael Mengel, a pathology researcher with the Faculty of Medicine & Dentistry, has found a new way to analyze biopsies from heart transplant patients by looking at their genes. This allows him to make an early prediction whether the transplant is working.

Childhood asthma risk linked with prenatal paracetamol exposure depends on antioxidant genes in mother

Evidence suggesting that the risk of childhood asthma associated with prenatal paracetamol exposure may depend on antioxidant genes in the mother has been found by a team of UK scientists. The results of their study - which strengthens the argument for a causal link between paracetamol exposure in early life and later childhood asthma - are published online (10 November) in the Journal of Allergy and Clinical Immunology.

New discovery can develop diagnostic test to identify gene mutation in AML

Decoding the DNA of a woman who died of acute myeloid leukemia (AML) has led researchers at Washington University School of Medicine in St. Louis to a gene that they found to be commonly altered in many patients who died quickly of the disease.
