RUB biologists deliberately transform spinal cord stem cells into immature nerve cells

RUB biologists have deliberately transformed stem cells from the spinal cord of mice into immature nerve cells. This was achieved by changing the cellular environment, known as the extracellular matrix, using the substance sodium chlorate.

Study reveals technique that allows scientists to watch lipid metabolism in live zebrafish

In mammals, most lipids are absorbed into the body via the small intestine. The complexity of the cells and fluids that inhabit this organ make it very difficult to study in a laboratory setting. New research from Carnegie's Steven Farber, James Walters and Jennifer Anderson reveals a technique that allows scientists to watch lipid metabolism in live zebrafish. This method enabled them to describe new aspects of lipid absorption that could have broad applications for human health.

Study explains why memory improves on a high-DHA diet

We've all heard that eating fish is good for our brains and memory. But what is it about DHA, an omega-3 fatty acid found in fish, that makes our memory sharper? Medical researchers at the University of Alberta discovered a possible explanation and just published their findings in the peer-reviewed journal Applied Physiology, Nutrition, and Metabolism.

Researchers identify genes that influence degeneration of the hippocampus

In a genome-wide association (GWA) study, researchers from Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) have identified several genes which influence degeneration of the hippocampus, the part of the brain most associated with Alzheimer disease (AD).

Novo Nordisk, BRI collaborate to speed-up translational research of autoimmune diseases

Benaroya Research Institute at Virginia Mason (BRI), a non-profit biomedical research institute in Seattle, Wash., and Novo Nordisk, a global health care company headquartered in Denmark, today announced a three-year collaborative agreement to potentially speed-up translational research of the diagnosis and treatment of rheumatoid arthritis, inflammatory bowel disease and lupus.

Researchers use DNA molecules to stimulate repair of nerve coatings that mimic MS

Mayo Clinic researchers have successfully used smaller, folded DNA molecules to stimulate regeneration and repair of nerve coatings in mice that mimic multiple sclerosis (MS). They say the finding, published today in the journal PLoS ONE, suggests new possible therapies for MS patients.

Boston College chemists use nanowires to power photosynthesis

Harnessing the power of the sun has inspired scientists and engineers to look for ways to turn sunlight into clean energy to heat houses, fuel factories and power devices. While a majority of this research focuses on energy production, some researchers are looking at the potential uses of these novel solar technologies in other areas.

Scientists use patient cells to generate human model of Huntington's

Scientists at the Gladstone Institutes and an international team of researchers have generated a human model of Huntington's disease-directly from the skin cells of patients with the disease.

Flu immunity depends on number of viruses involved during initial infection

Not only does the type of flu virus affect a patient's outcome, but a new research report appearing in the Journal of Leukocyte Biology suggests that the number of viruses involved in the initial infection may be important too.

Scientists use new method to assemble massive catalogue of data on proteins

Scientists at the Novo Nordisk Foundation Center for Protein Research at the University of Copenhagen have used a new method to assemble a massive catalogue of data on proteins. This gives them unprecedented insight into a process called protein phosphorylation.

New laboratory model for Huntington's disease

Cedars-Sinai scientists have joined with expert colleagues around the globe in using stem cells to develop a laboratory model for Huntington's disease, allowing researchers for the first time to test directly on human cells potential treatments for this fatal, inherited disorder.

Researchers probe origin of optimized antibodies against infections

An organism's ability to make new antibodies and use them to optimize its own immune defenses is of central importance in the fight against pathogens. In the case of severe infections, the overall relative speed with which an immune response proceeds could mean the difference between life and death.

Millennium introduces novel pharmacogenetic testing

Millennium Laboratories, the leading research-based clinical diagnostic company dedicated to improving the lives of people suffering from pain, announced today the introduction of Millennium Pharmacogenetic Testing.

Researchers create first animal model for RA

Researchers at Northwestern University Feinberg School of Medicine have created the first animal model that spontaneously develops rheumatoid arthritis (RA) and is predisposed towards atherosclerosis, or hardening of the arteries.

Scientists discover new gene in the influenza virus

Scientists have discovered a new gene in the influenza virus that helps the virus control the body's response to infection.

Researchers create 'Huntington's disease in a dish' to enable search for treatment

Johns Hopkins researchers, working with an international consortium, say they have generated stem cells from skin cells from a person with a severe, early-onset form of Huntington's disease (HD), and turned them into neurons that degenerate just like those affected by the fatal inherited disorder.

UTMB researchers improve existing experimental vaccine for Rift Valley fever virus

University of Texas Medical Branch researchers have significantly improved an existing experimental vaccine for Rift Valley fever virus, making possible the development of a more effective defense against the dangerous mosquito-borne pathogen.

Scientists identify abnormal gene that leads to Parkinson's

An international team including scientists from the University of Saskatchewan-Saskatoon Health Region and University of British Columbia, with the help of Saskatchewan Mennonite families, has identified an abnormal gene which leads to Parkinson's disease.

Prenatal exposure to PCBs impacts reproductive function in offspring

Prenatal exposure to the environmental contaminants polychlorinated biphenyls, or PCBs, causes long-term changes to the developing brain that have adverse effects on reproductive function later in life, a new study finds. Results will be presented Saturday at The Endocrine Society's 94th Annual Meeting in Houston.

Study suggests new treatment strategy for heart attacks and strokes

A heart attack doesn't just damage heart muscle tissue by cutting off its blood supply, it also sets off an inflammatory cascade that worsens underlying atherosclerosis, actively increasing the risk for a future heart attack. These findings from a study receiving advance online publication in Nature suggest an important new therapeutic strategy for preventing heart attacks and strokes, both of which are caused when atherosclerotic plaques rupture and block important blood vessels.
