Dentists could detect osteoporosis, automatically
Researchers in the School of Dentistry at The University of Manchester have created a unique way of identifying osteoporosis sufferers from ordinary dental x-rays.
Cold sore virus might play role in Alzheimer's
A gene known to be a major risk factor for Alzheimer's disease puts out the welcome mat for the virus that causes cold sores, allowing the virus to be more active in the brain compared to other forms of the gene. The new findings, published online in the journal Neurobiology of Aging, add some scientific heft to the idea, long suspected by some scientists, that herpes somehow plays a role in bringing about Alzheimer's disease. more
Peptide targets latent papilloma virus infections
While a newly marketed vaccine promises to drastically reduce human papilloma virus (HPV) infections, the major cause of cervical cancer, a new discovery by University of California, Berkeley, researchers could some day help the millions of people already infected and at constant risk of genital warts and cancer. more
Men with no sons more at risk for prostate cancer, according to Mailman School of PH Study
In a new and unique study to determine if genes on the Y chromosome are involved in prostate cancer, researchers at Columbia University's Mailman School of Public Health in conjunction with Hebrew University of Jerusalem found that men who had only daughters had a higher risk of prostate cancer than men who had at least one son, thus signifying a possible defect on the father's Y chromosome. The results, published in the January 3, 2007 issue of the Journal of the National Cancer Institute, further indicate that the relative risk of prostate cancer decreases as the number of sons increases. more
Interferon-treated hepatitis C patients likely to experience retinopathy
Persons with chronic hepatitis C being treated with Interferon (IFN) are at risk of developing retinopathy as early as two weeks into treatment according to the results of a new study published in the January 2007 issue of Investigative Ophthalmology & Visual Science (IOVS).
Hotspots of mercury contamination identified in eastern North America
A US and Canadian research team surveying mercury contamination in fish and birds in the northeastern United States and southeastern Canada has identified five "hotspots" where concentrations of the element exceed those established for human or wildlife health. The team focused on levels of the potent neurotoxin in yellow perch and common loons, but it also took into account contamination in other fish, birds, and mammals. In addition to these hotspots in New England, New York, and Nova Scotia, the researchers found nine "areas of concern" in these regions and in Quebec and New Brunswick. Findings from the team's analysis are summarized in the January 2007 issue of BioScience. more
Interviewing technique reduces risk for binge drinking and unplanned pregnancies
A University of Virginia Health System researcher and colleagues have just published findings showing that just a few targeted counseling sessions had a notably positive impact on women at high risk for binge drinking, unplanned pregnancy, and exposure to alcohol during pregnancy. The counseling technique, called motivational interviewing (MI), has proven effective after just four counseling sessions. In addition, Karen Ingersoll, Ph.D., has won a grant for $1.9 million from the National Institutes of Health to study how this effective counseling technique works. more
