Gene :: Fruit Fly Study Identifies Gene Mutation That Regulates Sensitivity to Alcohol

Researchers at the University of California, San Francisco (UCSF) have discovered a gene mutation in fruit flies that alters sensitivity to alcohol. The findings, reported in the October 6 issue of the journal Cell, may have implications for human studies seeking to understand innate differences in people?s tolerance for alcohol. The research was supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institute on Drug Abuse (NIDA) of the National Institutes of Health (NIH), part of the U.S. Department of Health and Human Services.

Dementia :: Researchers Discover Misfolded Protein Clumps Common to Dementia, Lou Gehrig?s Disease

Scientists have identified a misfolded, or incorrectly formed, protein common to two devastating neurological diseases, frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig?s disease), according to a report in the Oct. 6, 2006, issue of Science. The findings suggest that certain forms of FTD, ALS and possibly other neurological diseases might share a common pathological process.

DNA :: NHGRI Aims to Make DNA Sequencing Faster, More Cost Effective

Bethesda, Md. ? The National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), today announced the latest round of grant awards totaling more than $13.3 million to speed the development of innovative sequencing technologies that reduce the cost of DNA sequencing and expand the use of genomics in medical research and health care.

Irritable Bowel Syndrome :: Traveller’s diarrhoea may raise risk of IBS

People who experience traveller’s diarrhoea appear to be at significantly increased risk of subsequently suffering from irritable bowel syndrome (IBS), a condition characterised by abdominal pain, bloating, diarrhoea, and constipation.

Smoking :: Nabi biopharmaceuticals completes enrollment in nicvax phase iib ‘proof-of-concept’ clinical trial

Nabi Biopharmaceuticals (Nasdaq: NABI) today announced it has completed enrollment for its Phase IIB “proof-of-concept” study for NicVAX(R) (Nicotine Conjugate Vaccine), the company’s novel, innovative and proprietary investigational vaccine being developed to treat nicotine addiction and prevent smoking relapse. Enrollment for the trial was completed three months earlier than anticipated, paving the way for the release of trial results early in the second quarter of 2007.

Gene :: Does missing gene point to nocturnal existence for early mammals?

A gene that makes cells in the eye receptive to light is missing in humans, researchers have discovered. They say that whereas some animals like birds, fish and amphibians have two versions of this photoreceptor, mammals, including humans, only have one. The findings – published in the Public Library of Science journal PLoS Biology – reveal how our experience of the light environment may be impoverished compared to other vertebrates and fits with the suggestion that early mammals were at one time wholly nocturnal creatures.

Breast Cancer :: Regular exercise, keeping weight in check reduces breast-cancer risk in postmenopausal women

Postmenopausal women who want to significantly decrease their breast-cancer risk would be wise to exercise regularly and keep their weight within a normal range for their height, according to new findings from the Women’s Health Initiative to be published in the journal Obesity.

Nutrition :: Researchers look to solve mystery behind egcg and probiotics

When talking about nutrition, EGCG and probiotics are two words that we’ve been hearing a lot about these days. But most consumers don’t know what they are, where they are found and what they do. Some of that mystery was cleared up this week at the 47th Annual Symposia of the American College of Nutrition (ACN) where leading nutrition experts revealed new research about the health benefits of these two ingredients.

Breast Cancer :: Genetic alterations may explain racial disparity in breast cancer

Molecular and genetic alterations that cause tumors and drive the course of disease may someday explain the differences in incidence and mortality between African American and European American breast cancer patients. This is the conclusion of a literature review by a research team at Roswell Park Cancer Institute (RPCI) led by Christine B. Ambrosone, PhD, Chair of Epidemiology at RPCI. Results of the study are published in the September edition of Cancer Research.

Flu :: Novel way to protect against all flu, even pandemics

A novel way of slowing down the rate at which a flu virus infects the body could well become an effective protector from all types of influenza, even pandemics, say researchers from the University of Warwick, UK. Animal studies have shown this procedure protects against a wide range of influenza viruses.
