UTMB researchers awarded grant to study gene therapy techniques to eliminate neuropathic pain

University of Texas Medical Branch at Galveston researchers have been awarded a five-year, $1.8 million grant by the National Institute of Neurological Disorders and Stroke to apply the techniques of gene therapy to the problem of neuropathic pain - that is, pain that arises from a malfunction in the nervous system.

Scientists design 'fishing' technique to show health benefits of foods

New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells' "superpower" to escape death.

Genetic markers improve detection of individuals with high risk for CHD

The study comprised over 24,000 Finnish subjects and was led by Professor Samuli Ripatti. The results revealed that a panel of 28 genetic markers improved detection of individuals with high risk for coronary heart disease (10-year risk ≥20%) over traditional risk factors.

Researchers pinpoint catalytic trigger for onset of Alzheimer's disease

Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease - when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.

New breakthrough in progeria treatment

Pharmaceuticals that inhibit a specific enzyme may be useful in treating progeria, or accelerated aging in children. A new study performed at the Sahlgrenska Academy, University of Gothenburg, Sweden, indicates that the development of progeria in mice was inhibited upon reducing the production of this enzyme.

Researchers examine how BRD4 contributes to sustained presence of NF-kappa B in cancer cells

In a new study described in the journal Oncogene, researchers reveal how a key player in cell growth, immunity and the inflammatory response can be transformed into a primary contributor to tumor growth.

Measuring genetic diversity within tumor predicts outcomes of patients with head and neck cancer

A new measure of the heterogeneity - the variety of genetic mutations - of cells within a tumor appears to predict treatment outcomes of patients with the most common type of head and neck cancer.

Targeting glucagon action: A new frontier for regulating diabetes

For the first time, scientists at the Toronto General Research Institute showed that targeting glucagon action in the brain may be a new frontier for regulating diabetes.

Promising method to distinguish pancreatic cancer from chronic pancreatitis

Researchers at Mayo Clinic have developed a promising method to distinguish between pancreatic cancer and chronic pancreatitis - two disorders that are difficult to tell apart. A molecular marker obtained from pancreatic "juices" can identify almost all cases of pancreatic cancer, their study shows.

Joint replacement surgery might be avoidable in the future, suggest scientists

Scientists at Johns Hopkins have turned their view of osteoarthritis inside out. Literally. Instead of seeing the painful degenerative disease as a problem primarily of the cartilage that cushions joints, they now have evidence that the bone underneath the cartilage is also a key player and exacerbates the damage.

Certain varieties of clay have ability to kill MRSA, says ASU researcher

In the race to protect society from infectious microbes, the bugs are outrunning us. The need for new therapeutic agents is acute, given the emergence of novel pathogens as well as old foes bearing heightened antibiotic resistance.

Students receive Addiction Science Award at 2013 Intel International Science and Engineering Fair

An exploration of electronic "screen time" and sleep on mood, memory and learning was given the top Addiction Science Award at the 2013 Intel International Science and Engineering Fair - the world's largest science competition for high school students.

Researchers examine new zinc-based bioabsorbable stents

In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked by clots or plaque deposits. After about six months, most damaged arteries are healed and stay open on their own. The stent, however, is there for a lifetime.

Keystone molecules in chemical communication, defense have dominant consequences in nature

Naturally occurring "keystone" molecules that have powerful behavioral effects on diverse organisms often play large but unrecognized roles in structuring ecosystems, according to a theory proposed in the June issue of BioScience.

Non-invasive brain stimulation techniques improve memory

Non-invasive brain stimulation techniques aimed at mental and neurological conditions include transcranial magnetic stimulation for depression, and transcranial direct current (electrical) stimulation, shown to improve memory.

Understanding the role of dsRNA in antiviral host defense systems

Animals, insects, and plants use a variety of sensing mechanisms to detect invading pathogens such as viruses. One complex and effective antiviral defense system they share is based on recognition of double-stranded RNA, often produced when a virus invades a host cell.

Leslie G. Ungerleider to receive Andrew Carnegie Prize in Mind and Brain Sciences from Carnegie Mellon

Carnegie Mellon University will award the first Andrew Carnegie Prize in Mind and Brain Sciences to Leslie G. Ungerleider, chief of the Laboratory of Brain and Cognition at the National Institute of Mental Health.

Research: Women's reproductive function may be tied to their immune status

New research indicates that women's reproductive function may be tied to their immune status. Previous studies have found this association in human males, but not females.

Innovative X-ray method advances new treatments for genetic diseases

An international team of scientists using a new X-ray method recorded the internal structure and cell movement inside a living frog embryo in greater detail than ever before.

Study: VEGF inhibitor appears to improve glaucoma surgical outcomes

The most common cause of failure after glaucoma surgery is scarring at the surgical site, so researchers are actively looking for ways to minimize or prevent scar formation. Previous work had suggested that vascular endothelial growth factor (VEGF) activates fibrosis, whereas VEGF inhibition results in reduced scar formation and better surgical results.
