IBN scientists harness ultrasmall peptides to repair spinal disc damage

New ultrasmall peptides that can be used as building blocks for a wide range of regenerative applications such as spinal disc replacement and cartilage repair have been developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute. These peptides spontaneously assemble in water to form hydrogels, which resemble collagen, a major component of connective tissues found in cartilage, ligaments, tendons, bone and skin.

Crocus plant to provide a tumor killing “smart bomb”

According to the latest research, a drug derived from plant extracts could wipe out tumors in a single treatment with minimal side effects. Scientists have turned a chemical found in crocuses into a ‘smart bomb’ that targets cancerous tumors. The advantage is that healthy tissue is unharmed, reducing the odds of debilitating side effects. And unlike other side effect-free drugs, it is able to kill off more than one type of the disease, including breast, prostate, lung and bowel cancer. Potentially, all solid tumours could be vulnerable to drugs developed this way, meaning it could be used against all but blood cancers.

Mayo Clinic develops genome-based immunization strategy against feline AIDS

Mayo Clinic researchers have developed a genome-based immunization strategy to fight feline AIDS and illuminate ways to combat human HIV/AIDS and other diseases. The goal is to create cats with intrinsic immunity to the feline AIDS virus. The findings -- called fascinating and landmark by one reviewer -- appear in the current online issue of Nature Methods.

General anesthesia can cause cognitive impairment in children

General anesthesia administered to the developing animal brain depresses much needed neuronal activity and communication resulting in long-lasting cognitive impairment, according to an article published in the August issue of Current Opinion in Anesthesiology.

Scientists successfully disrupt function of MYC cancer gene

Dana-Farber Cancer Institute scientists have successfully disrupted the function of a cancer gene involved in the formation of most human tumors by tampering with the gene's "on" switch and growth signals, rather than targeting the gene itself.

LC-MRM could provide better understanding of multiple myeloma drug resistance

"Acquired drug resistance" (ADR) is a major problem encountered in treating some forms of cancer. The ability to monitor the proteins involved in drug resistance has been a hurdle facing cancer researchers.

Preliminary research shows how Fusarium microbes travel through the air

Preliminary research on Fusarium, a group of fungi that includes devastating pathogens of plants and animals, shows how these microbes travel through the air. Researchers now believe that with improvements on this preliminary research, there will be a better understanding about crop security, disease spread, and climate change.

New treatment strategy for dominant forms of muscular dystrophy

Investigators at The Research Institute at Nationwide Children's Hospital are studying a potential new treatment strategy for dominant forms of muscular dystrophy, thanks to preliminary funding from The Ohio State University Center for Clinical and Translational Science.

Human gliomas release excess levels of glutamate and trigger seizures

Glioma, one of the most deadly and common types of brain tumor, is often associated with seizures, but the origins of these seizures and effective treatments for them have been elusive. Now a team funded by the National Institutes of Health has found that human gliomas implanted in mice release excess levels of the brain chemical glutamate, overstimulating neurons near the tumor and triggering seizures.

Researchers describe new function of HCN channels in the heart

The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle cells (depolarization) through channels in their membranes, and are followed by a compensating reverse ion current (repolarization), which restores the original state. If the duration of the repolarization phase is not just right, the risk of ventricular arrhythmia and sudden cardiac death increases significantly.

Common genetic variant may predispose people to acute dissections

Richard Holbrooke, John Ritter, Lucille Ball, Jonathan Larson and Great Britain's King George II were all taken by the same silent killer: an acute aortic dissection. Now, scientists led by researchers at The University of Texas Health Science Center at Houston and Baylor College of Medicine have found an association with a common genetic variant in the population that predisposes people to acute dissections and can approximately double a person's chances of having the disease.

WSU researcher receives $418,000 NINDS grant to study spinal muscular atrophy

Graham Parker, Ph.D., assistant professor of research in the Department of Pediatrics at Wayne State University's School of Medicine, was awarded $418,000 from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health to study how a particular gene might be involved in the progression of spinal muscular atrophy (SMA) - the number one genetic killer of children younger than 2 years old.

Researchers identify 29 DNA sequence variations linked with blood pressure

A study involving more than 200,000 people worldwide has identified 29 DNA sequence variations in locations across the human genome that influence blood pressure.

Researchers discover 16 new gene regions that influence blood pressure

Findings, published today in Nature and Nature Genetics by the International Consortium for Blood Pressure Genome-Wide Association Studies represent a major advance in our understanding of the inherited influences on blood pressure and offer new potential therapeutic targets for prevention of heart disease and stroke - the biggest cause of death worldwide.

Study pinpoints relationship between primary brain tumors and onset of epileptic seizures

New research from the University of Alabama at Birmingham pinpoints the relationship between primary brain tumors and the onset of epileptic seizures and reveals that a drug used to treat Crohn's disease inhibits those seizures and may be able to slow a tumor's growth.

Researchers demonstrate connection between circadian rhythm, platelet function and cardiovascular risk

Researchers at Brigham and Women's Hospital (BWH) have demonstrated that the circadian system, the body's internal clock, regulates human platelet function and causes a peak in platelet activation corresponding to the known morning peak in adverse cardiovascular events. These findings are published in PLoS ONE on September 8, 2011.
