Aging reduces axonal regeneration after spinal cord injury

Older Americans are increasingly active, and this lifestyle shift has contributed to the rise in average age of a person experiencing a spinal cord injury. The changing demographic calls for a better understanding of how aging impacts recovery and repair after a spinal cord injury.

Tumor suppressor p53 gene twice as likely to be defective in autistic children

A large study by researchers with the UC Davis MIND Institute has found that a gene whose role is to suppress cellular damage from environmental stressors is nearly twice as likely to be defective in children with autism spectrum disorder (ASD), and that the deficit is also present in their fathers.

Experimental urine test identifies 92% of men with elevated PSA levels

An experimental urine test that detects genetic changes associated with prostate cancer identified 92 percent of men with elevated PSA (prostate-specific antigen) levels who had high-grade cancers, according to a study published today in JAMA Oncology online.

Study points to possible new genetic risk factor for celiac disease

Researchers have identified a common variant in a non-coding RNA that may contribute to the intestinal inflammation that occurs in people with celiac disease. The findings point to a possible new risk factor for developing celiac disease in people with celiac disease risk genes.

Commonly used fungicides could cause gene expression changes in brain cells

Scientists at the UNC School of Medicine have found a class of commonly used fungicides that produce gene expression changes similar to those in people with autism and neurodegenerative conditions, including Alzheimer's disease and Huntington's disease.

Right side of the brain reorganizes itself after stroke to help recover speech-motor functions

New research suggests that looking at structures in the right side of the brain may help predict who will better recover from language problems after a stroke, according to a study published in Neurology, a medical journal of the American Academy of Neurology.

Penn researchers discover molecular mechanism that underlies common cerebrovascular disease

Cerebral cavernous malformations (CCMs) are clusters of dilated, thin-walled blood vessels in the brain that can cause stroke and seizures, yet exactly how they form is somewhat of a mystery. Now, a team from the Perelman School of Medicine at the University of Pennsylvania has discovered the molecular mechanism that underlies this common cerebrovascular disease. They published their results this week online ahead of print in Nature.

Scientists develop mouse model to gain new insights into genetic mechanisms underlying AML

A novel mouse model of a highly lethal form of acute myeloid leukemia (AML) offers a new tool for scientists working to better understand this disease and research new therapeutic targets.

Understanding neuronal feedback could provide new insight into visual perception

Ever see something that isn't really there? Could your mind be playing tricks on you? The "tricks" might be your brain reacting to feedback between neurons in different parts of the visual system, according to a study published in the Journal of Neuroscience by Carnegie Mellon University Assistant Professor of Biological Sciences Sandra J. Kuhlman and colleagues.

Study finds correlation between male sex hormones and oral health

More than 20 species of macaques, the most widely distributed nonhuman primates in the world, socialize in lively troops and make frequent appearances on National Geographic documentaries. But, what can we learn from one of our closest primate relatives about our own oral health?

LMU-led researchers define previously unknown signaling pathway that triggers inflammation

Using a combination of newly developed methods, researchers led by Ludwig-Maximilians-Universitaet (LMU) in Munich immunologist Veit Hornung have defined a previously unknown pathway that triggers inflammation.

Scientists identify RingoA protein as key regulator of meiosis

Published today in Nature Communications, a study by scientists at the Institute for Research in Biomedicine headed by ICREA researcher Angel R. Nebreda has reported that the protein RingoA is a key regulator of meiosis--the cell division process that gives rise to ovules and sperm for sexual reproduction in mammals.

New Rutgers study links protein that helps fight infection to heart and liver disease

A protein that should help fight infection and keep us healthy may be targeted for treating devastating illnesses like heart and liver disease, according to a new Rutgers study.

FDA announces availability of investigational test to screen donated blood for Zika virus

The U.S. Food and Drug Administration today announced the availability of an investigational test to screen blood donations for Zika virus. The screening test may be used under an investigational new drug application (IND) for screening donated blood in areas with active mosquito-borne transmission of Zika virus.

Mom needs to get more vitamin D during second trimester to reduce child's asthma risk

The best way to reduce a child's chances of developing asthma might be making sure Mom had enough vitamin D during the second trimester, a new study from the University of Kansas shows.

UCJC study reveals excessive electrolyte loss may lead to hyponatraemia

Spanish researchers have analysed how the sodium lost through sweat during a marathon influences the maintenance of stable and physiologically sound conditions that allow the body to carry out its functions. Excessive electrolyte loss may lead to a medical problem known as hyponatraemia.

Measuring brain signal variability could help identify patients at higher risk of dementia

Dementia will develop in about 80% of patients with Parkinson's disease, and a new study has found significant variability in brain signaling that could serve as a predictive marker for identifying which patients are at highest risk of dementia.
