Antioxidant :: Antioxidants could provide all-purpose radiation protection

Two common dietary molecules found in legumes and bran could protect DNA from the harmful effects of radiation, researchers from the University of Maryland report. Inositol and inositol hexaphosphate (IP6) protected both human skin cells and a skin cancer-prone mouse from exposure to ultraviolet B (UVB) radiation, the damaging radiation found in sunlight, the team reported today at the American Association for Cancer Research Centennial Conference on Translational Cancer Medicine.

Colorectal Cancer :: Curry-derived molecules might be too spicy for colorectal cancers

Curcumin, the yellowish component of turmeric that gives curry its flavor, has long been noted for its potential anti-cancer properties. Researchers from Tohoku University in Sendai, Japan, report on an apparent improvement upon nature: two molecular analogues of curcumin that demonstrate even greater tumor suppressive properties.

Lung Cancer :: Study identifies novel gene alterations in lung cancer

An international team of scientists, supported in part by the National Human Genome Research Institute (NHGRI), one of the National Institutes of Health (NIH), announced that its systematic effort to map the genomic changes underlying lung cancer has uncovered a critical gene alteration not previously linked to any form of cancer. The research, published in the advance online issue of the journal Nature, also revealed more than 50 genomic regions that are frequently gained or lost in lung adenocarcinoma, the most common type of lung cancer in the United States.

Aged :: Older adults not more distractible, research shows

Despite previous research suggesting that older adults are more distractible, new research shows they are no more distractible than younger adults when asked to focus their attention on their sense of sight or sound, or when asked to switch their attention from one sense to the other.

Heart :: Harvard researcher wins prize for identifying destructive heart changes

The American Heart Association awarded its Clinical Research Prize to a Harvard researcher for identifying destructive structural changes in the diseased heart and leading clinical trials showing that lifesaving therapies can limit damage.

Healthcare :: NSF awards Stevens team $1 million for research on smart, bacteria-repellent nanohydrogels

The National Science Foundation (NSF) has awarded an interdisciplinary team of five Stevens Institute of Technology researchers a four-year, $1 million grant to develop “smart, self-assembling nano-biomaterials that can control whether bacteria will adhere to synthetic surfaces, allowing for carefully targeted control over microscopic processes that occur within the human body.

Muscular Atrophy :: Molecular medical research points to treatment of spinal muscular atrophy

SMA is the second most prevalent genetic cause of infant death in the UK, after cystic fibrosis. Studies show that between 1:50 and 1:34 of the population are carriers of the disease, and that it affects in the region of 1:10,000 children born in the UK. In the USA, 1:40 are carriers and 1:6,000 children are affected by the disease.

HIV :: A hairpin to fight HIV

When a host cell is infected with HIV, the virus brings its own genetic material into the host cell. This cell then replicates, reads the viral RNA, and uses it as a blueprint to produce more viral proteins. Complete viruses are then released to attack the next cells.

Lung :: Treat all patients with rare lung disease to prevent stroke, say doctors

Treatment should be offered to all people with a particular rare lung condition, regardless of whether or not they show symptoms of it, say researchers and doctors behind a new study published today.

Obesity :: Possible link between obesity and viral infections

Experts don’t dispute the important role that diet and activity play in maintaining a healthy weight. But can poor eating habits and a less active lifestyle fully explain the prevalence of obesity in the United States today? That question has led some researchers to ask whether there might be other causes for this serious problem. In the October issue of Mayo Clinic Proceedings, researcher Richard Atkinson, M.D., asserts that there is a growing body of evidence demonstrating that viruses may play a role in causing obesity in humans.
