Attenuation of NASH by stimulation of free fatty acid metabolism
Medically-complicated obesity is a societal problem that needs to be solved. Liver disease, specifically non-alcoholic steatohepatitis or NASH, is just one of the many complications of increased body weight.   view more (2007-10-29)

Walking prevents bone loss caused from prostate cancer treatment
Exercise may reduce, and even reverse, bone loss caused by hormone and radiation therapies used in the treatment of localized prostate cancer, thereby decreasing the potential risk of bone fractures and improving quality of life for these men.   view more (2007-10-29)

'Knocking Out' Cell Receptor May Help Block Fat Deposits in Tissues, Prevent Weight Gain
University of Cincinnati (UC) pathologists have identified a new molecular target that one day may help scientists develop drugs to reduce fat transport to adipocytes (fat cells) in the body and prevent obesity and related disorders, like diabetes.   view more (2007-10-26)

Contribution of cholesterol transporter to vascular disease
Low-density lipoprotein (LDL), a transporter of cholesterol, may also contribute to vascular diseases by a previously unidentified mechanism, according to a report published online this week in EMBO reports.   view more (2007-10-26)

Food restriction increases dopamine receptor levels in obese rats
A brain-imaging study of genetically obese rats conducted at the U.S. Department of Energy's Brookhaven National Laboratory provides more evidence that dopamine - a brain chemical associated with reward, pleasure, movement, and motivation - plays a role in obesity.   view more (2007-10-25)

Accessory protein determines whether pheromones are detected

Structure of influenza B virus protein gives clues to next pandemic
Determining the structure of a protein called hemagglutinin on the surface of influenza B is giving researchers at Baylor College of Medicine and Rice University in Houston clues as to what kinds of mutations could spark the next flu pandemic.   view more (2007-10-16)

Genes that both extend life and protect against cancer identified
A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported today in the journal "Nature Genetics" identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm.   view more (2007-10-15)

How does the opioid system control pain, reward and addictive behavior?
The opioid system controls pain, reward and addictive behaviors. Opioids exert their pharmacological actions through three opioid receptors, mu, delta and kappa whose genes have been cloned (Oprm, Oprd1 and Oprk1, respectively).   view more (2007-10-15)

Media Availability: Low-Fat Dietary Pattern May Lower Risk of Ovarian Cancer -- The WHI Dietary Modification Trial
A diet low in fat could reduce the risk of ovarian cancer in healthy postmenopausal women, according to new results from the Women's Health Initiative (WHI) Dietary Modification Trial. Researchers found that after four years, women who decreased the amount of dietary fat they consumed were 40... view more (2007-10-10)

Hip size of mothers linked to breast cancer in daughters
In a study of the maternity records of more than 6,000 women, David J.P. Barker, M.D., Ph.D., and Kent Thornburg, Ph.D., of Oregon Health & Science University discovered a strong correlation between the size and shape of a woman's hips and her daughter's risk of breast cancer. Wide, round hips,... view more (2007-10-08)

Scripps research scientists develop innovative dual action anthrax vaccine-antitoxin combination

Brown Researchers Make Major Signal Transduction Discovery
The chemical process known as acetylation plays a central role in cytokine receptor signal transduction - a fundamental biochemical cascade inside cells that controls the activity of antiviral and tumor-suppressing genes.   view more (2007-10-05)

What emotional memories are made of
Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences.   view more (2007-10-05)

Linking 2 molecular pieces of the Alzheimer's puzzle
Researchers have uncovered a biological link between the protein whose mutation causes early-onset Alzheimer's disease (AD) and a gene variant linked to late-onset AD. The researchers said their finding could lead to new approaches to treating AD.   view more (2007-10-04)

First significant genetic finding in severe PMS, or PMDD
