Regenerating sensory hair cells could help treat hearing loss

Regenerating sensory hair cells, which produce electrical signals in response to vibrations within the inner ear, could form the basis for treating age- or trauma-related hearing loss. One way to do this could be with gene therapy that drives new sensory hair cells to grow.

Even mild head injuries can cause abnormalities in brain function

Even mild head injuries can cause significant abnormalities in brain function that last for several days, which may explain the neurological symptoms experienced by some individuals who have experienced a head injury associated with sports, accidents or combat, according to a study by Virginia Commonwealth University School of Medicine researchers.

FDA advisory committee supports lorcaserin for weight management

Arena Pharmaceuticals, Inc. and Eisai Inc. announced today that the US Food and Drug Administration Endocrinologic and Metabolic Drugs Advisory Committee voted 18 to 4, with one abstention, that the available data demonstrate that the potential benefits of lorcaserin outweigh the potential risks when used long-term in a population of overweight and obese individuals.

Less invasive procedure for heart disease

Doctors at Regions Hospital have begun performing a less invasive procedure for heart disease. Transcatheter aortic valve replacement (TAVR) was approved last November by the U.S. Food and Drug Administration for elderly patients who are too frail or too old for open heart surgery. The device is not approved for patients who are eligible for open heart surgery.

Researchers develop new form of specially bred mouse that mimics ADHD

The number of attention deficit hyperactivity disorder (ADHD) cases in the United States are exploding. According to a 2011 statement by the Centers for Disease Control and Prevention, nearly one in 10 American children is diagnosed with the disorder.

Excess brain activity contributes to amnestic mild cognitive impairment

A study led by a Johns Hopkins neuroscientist and published in the May 10 issue of the journal Neuron suggests a potential new therapeutic approach for improving memory and interrupting disease progression in patients with a form of cognitive impairment that often leads to full-blown Alzheimer's disease.

Eisai, Arena announce expansion of lorcaserin marketing and supply agreement

Arena Pharmaceuticals, Inc. and Eisai Inc. announced today the expansion of the lorcaserin marketing and supply agreement between Arena Pharmaceuticals, Inc.'s wholly owned subsidiary, Arena Pharmaceuticals GmbH, and Eisai Inc. Lorcaserin is an investigational drug candidate intended for weight management.

MAGI genes play a role in psychiatric disease

These findings are not about the classic story of gift-giving, although the MAGI genes (officially named membrane associated guanylate kinase, WW and PDZ domain containing proteins) do influence brain function in important ways.

New approach to advance quality of pregnancy monitoring

The University of California, San Diego Jacobs School of Engineering announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation. Bioengineering Professor Todd Coleman, in collaboration with Materials Science and Engineering Professor John A. Rogers at the University of Illinois at Urbana-Champaign, will pursue an innovative global health and development research project, titled "Epidermal Electronics for Continuous Pregnancy Monitoring."

Genes determine brain size: Global brain study

In the world's largest study of the human brain, involving more than 200 scientists worldwide, researchers have found that genes that affect brain size may play a part in intelligence and memory function. The study was put together by combining brain scans and genetic data from 21,000 people worldwide.

Study compares three new methods to study disorders of consciousness

Disorders of consciousness such as coma or a vegetative state caused by severe brain injury are poorly understood and their diagnosis has relied mainly on patient responses and measures of brain activity. However, new functional and imaging-based diagnostic tests that measure communication and signaling between different brain regions may provide valuable information about the potential for consciousness in patients unable to communicate. These innovative approaches are described and compared in a Review article in the groundbreaking neuroscience journal Brain Connectivity, a bimonthly peer-reviewed publication from Mary Ann Liebert, Inc., publishers.

KLF15 molecule inhibits action of estrogen in the endometrium

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a molecule that inhibits the action of estrogen. This female hormone plays a key role in the growth, maintenance and repair of reproductive tissues and fuels the development of endometrial and breast cancers.

Scientists pinpoint mechanism essential for memory formation

Now, in a study that appears in the May 10, 2012 issue of the journal Neuron, scientists from the Florida campus of The Scripps Research Institute have pinpointed a mechanism that is essential for forming memories in the first place and, as it turns out, is equally essential for eliminating them after memories have formed.

Chronic exposure to cocaine drives structural changes in the brain

Chronic exposure to cocaine reduces the expression of a protein known to regulate brain plasticity, according to new, in vivo research on the molecular basis of cocaine addiction. That reduction drives structural changes in the brain, which produce greater sensitivity to the rewarding effects of cocaine.

Janssen submits XARELTO sNDA with FDA to reduce risk of stent thrombosis in ACS patients

Janssen Research & Development, LLC announced today that it has submitted a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) seeking approval for the use of XARELTO, an oral anticoagulant, to reduce the risk of stent thrombosis in patients with Acute Coronary Syndrome.

Non-drug therapy with NeuroStar TMS improves depression symptoms and QOL

New data released today at the annual meeting of the American Psychiatric Association show that patients with unipolar, non-psychotic Major Depressive Disorder (MDD) receiving transcranial magnetic stimulation (TMS) with NeuroStar TMS Therapy achieved significant improvements in both depression symptoms and in quality of life measurements.

Antidepressives reduce risk of suicides in schizophrenic patients

Antidepressive drugs reduce the mortality rate of schizophrenic patients, while treatment with bensodiazepines greatly increases it, especially as regards suicide. Giving several antipsychotics simultaneously, however, seems to have no effect at all. This according to a new study examining different drug combinations administered to patients with schizophrenia.

Study shows how adolescent cannabis use can cause schizophrenia

New research from the Royal College of Surgeons in Ireland (RCSI) published in Nature's Neuropsychopharmacology has shown physical changes to exist in specific brain areas implicated in schizophrenia following the use of cannabis during adolescence. The research has shown how cannabis use during adolescence can interact with a gene, called the COMT gene, to cause physical changes in the brain.

Chemically altered proteins may be key to understanding memories

Having a fat head may not be a bad thing, according to new findings at The Johns Hopkins University. As reported in the February 9 issue of Neuron, researchers have made a significant discovery as to how adding fat molecules to proteins can influence the brain circuitry controlling cognitive function, including learning and memory.
