Three new genetic associations identified for primary open angle glaucoma

Researchers from Massachusetts Eye and Ear/Harvard Medical School and Case Western Reserve University School of Medicine have led an international effort to identify three genetic associations that influence susceptibility to primary open angle glaucoma -- the most common form of adult onset glaucoma and the leading cause of irreversible blindness in the world.

UTA researchers map out chemical mechanism of key enzyme found in autism, Alzheimer's and Down syndrome

Biochemists at The University of Texas at Arlington are mapping the catalytic processes of sulfur-oxidizing enzymes to improve understanding of the chemical imbalances found in patients with autism, Alzheimer's disease and Down syndrome.

Could statins treat muscular dystrophy? An interview with Dr. Nick Whitehead and Dr Stan Froehner

In addition to their well established cholesterol lowering benefits, statins also have potent anti-inflammatory, anti-fibrotic and antioxidant effects, which continue to be identified in a wide range of diseases.

WPI researchers awarded $1.3 million NIH grant to study use of copper to battle bacterial invader

Copper is an essential micronutrient that all organisms need to maintain healthy metabolism. But unless it is bound to proteins, copper is also toxic to cells. With a $1.3 million award from the National Institutes of Health, researchers at Worcester Polytechnic Institute will conduct a systematic study of copper in the bacteria Pseudomonas aeruginosa (P. aeruginosa), a leading cause of hospital-associated infections that is increasingly resistant to antibiotics, with the hope of discovering new drug targets that might allow cells in the body to use copper to fight back against this bacterial invader.

MCG researchers explore how neurofibromatosis puts young patients at risk for cardiovascular disease

It's a fairly common genetic condition that can surface as a series of dark skin spots and result in a host of maladies from tumors to premature cardiovascular disease. Medical College of Georgia researchers hope their studies of how neurofibromatosis 1, or NF1, can dangerously thicken or thin blood vessel walls will one day help physicians better identify and treat these young patients at cardiovascular risk.

Genetic reduction of AMPK enzyme can prevent or delay hearing loss

A mitochondrial defect is responsible for a type of human hereditary deafness that worsens over time and can lead to profound hearing loss.

Study reports discovery of new class of DNA repair enzyme

This year's Nobel Prize in chemistry was given to three scientists who each focused on one piece of the DNA repair puzzle. Now a new study, reported online Oct. 28 in the journal Nature, reports the discovery of a new class of DNA repair enzyme.

New single-agent phototherapy system may form valuable new tool to combat cancer

Researchers at Oregon State University today announced an important advance in the field of cancer imaging and phototherapy, using a single-agent system that may ultimately change the efficacy of cancer surgery and treatment around the world.

Findings suggest link between cancer drug resistance and reactive oxygen species found in mitochondria

Increased levels of certain chemically reactive, oxygen-containing molecules in the body can cause patients to become resistant to cancer drugs such as chemotherapy, according to researchers at Georgia State University.

Discovery allows study of naturally occurring forms of HCV in the lab

Worldwide, 185 million people have chronic hepatitis C. Since the late 1980s, when scientists discovered the virus that causes the infection, they have struggled to find ways to grow it in human cells in the lab -- an essential part of learning how the virus works and developing new effective treatments.

Researchers use advanced photodynamic therapy to combat ovarian cancer in laboratory animals

Researchers at Oregon State University have made a significant advance in the use of photodynamic therapy to combat ovarian cancer in laboratory animals, using a combination of techniques that achieved complete cancer cell elimination with no regrowth of tumors.

Study suggests potential target for treating familial form of ALS

A healthy motor neuron needs to transport its damaged components from the nerve-muscle connection all the way back to the cell body in the spinal cord. If it cannot, the defective components pile up and the cell becomes sick and dies. Researchers at the NIH's National Institute of Neurological Disorders and Stroke have learned how a mutation in the gene for superoxide dismutase 1 (SOD1), which causes ALS, leads cells to accumulate damaged materials.

Sigma 1 receptor appears to play vital role in supporting the retina

A receptor that is already a target for treating neurodegenerative disease also appears to play a key role in supporting the retina, scientists report.

TSRI study shows antioxidants slow aging process, reduce risk of infection

Scientists from the Florida campus of The Scripps Research Institute have shown how aging cripples the production of new immune cells, decreasing the immune system’s response to vaccines and putting the elderly at risk of infection.

Researchers demonstrate direct connection between NOX proteins and liver fibrosis

Researchers at the University of California, San Diego School of Medicine have demonstrated a direct connection between two signaling proteins and liver fibrosis, a scarring process underlying chronic liver disease, the 12th leading cause of death in the United States.

Study provides new insights into mechanism that controls differences in gut's ability to fight infections

Considering how many microorganisms we ingest each day, our gut has an extensive and well-developed immune system. This defense is involved in acute and chronic gut diseases, but it varies dramatically among people. A persistent question is how our genetic make-up affects our gut's ability to fight infections. EPFL scientists have found that gut immunity is not affected by single genes but by entire groups of genes.

Metabolic imbalance caused by radiation from wireless devices linked to many health risks

A metabolic imbalance caused by radiation from your wireless devices could be the link to a number of health risks, such as various neurodegenerative diseases and cancer, a recent study suggests.

Aging may trigger adaptive response to offset effects of oxidative stress on blood vessels

Although the causes of many age-related diseases remain unknown, oxidative stress is thought to be the main culprit. Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress.
