Researchers identify protein that affects production of extracellular vesicles

Researchers at NYU Langone Medical Center have discovered a protein called TAT-5 that affects the production of extracellular vesicles, small sacs of membrane released from the surface of cells, capable of sending signals to other cells.

New computer chip models how neurons communicate with each other at synapses

For decades, scientists have dreamed of building computer systems that could replicate the human brain's talent for learning new tasks. MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain's neurons adapt in response to new information. This phenomenon, known as plasticity, is believed to underlie many brain functions, including learning and memory.

DNP effectively identifies structure of biological proteins in small samples

Researchers from Hull, Bristol and Frankfurt have shown that a new technique for identifying molecular structure can be used effectively on small samples of biological proteins, particularly proteins that are targeted for drug development.

Scientists discover promising approaches for treatment of pain

Scientists are discovering promising approaches to treating pain, one of the most common and debilitating neurological complaints, according to research released today at Neuroscience 2011, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

Researchers identify how to design drugs to target specific brain areas

The future of drug design lies in developing therapies that can target specific cellular processes without causing adverse reactions in other areas of the nervous system. Scientists at the Universities of Bristol and Li-ge in Belgium have discovered how to design drugs to target specific areas of the brain.

Low-grade inflammatory processes drive development of osteoarthritis

In a study to be published online Nov. 6 in Nature Medicine, investigators at the Stanford University School of Medicine have shown that the development of osteoarthritis is in great part driven by low-grade inflammatory processes.

Study finds spinal bleeding in young children with abusive head trauma

A new study found that spinal bleeding is found often in young children who are victims of abusive trauma. The findings support performing complete spine imaging for children undergoing brain magnetic resonance imaging (MRI) for moderate or severe traumatic brain injury and suggest a pathway for distinguishing between abusive and accidental injury.

MRSA co-infection increases risk of flu-related mortality among children

During the 2009 H1N1 influenza pandemic, many previously healthy children became critically ill, developing severe pneumonia and respiratory failure, sometimes fatal. The largest nationwide investigation to date of influenza in critically ill children, led by Children's Hospital Boston, found one key risk factor: Simultaneous infection with methicillin-resistant Staphylococcus aureus (MRSA) increased the risk for flu-related mortality 8-fold among previously healthy children.

X-ray crystallography identifies structure of apoA-I molecule

Using a sophisticated technique of x-ray crystallography, researchers Xiaohu Mei, PhD, and David Atkinson, PhD, from Boston University School of Medicine (BUSM) have for the first time obtained an "image" of the structure and the precise arrangement of the atoms in a truncated form of the apolipoprotein A-I (apoA-I) molecule.

Eliminating senescent cells could prevent or delay onset of age-related disorders

Researchers at Mayo Clinic have shown that eliminating cells that accumulate with age could prevent or delay the onset of age-related disorders and disabilities. The study, performed in mouse models, provides the first evidence that these "deadbeat" cells could contribute to aging and suggests a way to help people stay healthier as they age.

Scientists identify distinct tobacco transporter for nicotine metabolism

A team of Virginia Tech and Purdue University scientists have identified a distinct transporter used by tobacco plant cells for nicotine metabolism. The research appears in the Oct. 17 online before print issue of the Proceedings of the National Academy of Sciences (PNAS) in the article, "A tobacco nicotine uptake permease effects alkaloid metabolism."

ECMO and heart procedures performed as a bridge to lung transplantation

Surgeons at UK HealthCare recently became the first ever to perform two specific procedures together as a bridge to lung transplantation. Wanda Craig, of Lexington, Ky., is the first patient in history to receive these procedures, and at the age of 68, she is also the oldest living human to be bridged to transplant using an artificial lung device, also known as an extracorporeal membrane oxygenation (ECMO).

Aspirin may reduce risk of bowel cancer by half: Study

According to a new study published in The Lancet, a regular dose of aspirin may not only stave off heart disease but also cut the risk of developing hereditary cancer in half.

Neutralization approach appears to prevent proliferative vitreoretinopathy

Proliferative vitreoretinopathy (PVR), or the formation of scar tissue within the eye, is a serious, sight-threatening complication in patients recovering surgical repair of retinal detachment. A new study conducted by investigators at the Schepens Eye Research Institute, the Department of Ophthalmology at Harvard Medical School, and the Massachusetts Eye and Ear Infirmary in Boston, published in the December issue of the American Journal of Pathology, suggests that a cocktail containing reagents to neutralize a relatively small subset of vitreal growth factors and cytokines may be an effective treatment.

Study: Reduced secretion of beta-amyloid signals beginning of Alzheimer's

For decades the amyloid hypothesis has dominated the research field in Alzheimer's disease. The theory describes how an increase in secreted beta-amyloid peptides leads to the formation of plaques, toxic clusters of damaged proteins between cells, which eventually result in neurodegeneration. Scientists at Lund University, Sweden, have now presented a study that turns this premise on its head.

Spinal cord meninges is a potential source of self-renewing stem cells

Italian and Spanish scientists studying the use of stem cells for treating spinal cord injuries have provided the first evidence to show that meninges, the membrane which envelops the central nervous system, is a potential source of self-renewing stem cells.

Researchers uncover molecular pathway critical to cardiac arrhythmia

University of Maryland School of Medicine researchers have uncovered a previously unknown molecular pathway that is critical to understanding cardiac arrhythmia and other heart muscle problems.

Comprehensive ADMESeq Research Screening Panel launched

RainDance Technologies, Inc., the Digital Biology Company, and Ambry Genetics, today announced the launch of a comprehensive targeted sequencing panel to screen genes involved with drug absorption, distribution, metabolism, and excretion (ADME) research. The ADMESeq Research Screening Panel enables researchers to simultaneously interrogate 242 known pharmacogenetic genes using next-generation sequencing (NGS) systems.

Australian researchers make a quantum leap in understanding key cell structures

Researchers in Australia and the UK have made a world first discovery that will provide the most accurate understanding to date of the structure and function of the most important energy converting protein, critical to the function of all organs and a cause of disease when malfunctioning.
