Scientists have long known that people who have a close relative with alcohol problems themselves run an increased risk of starting to abuse alcohol. The reason for this has not been known, but a new study from the University of Gothenburg, Sweden, provides part of the answer. The study shows that people who have a close relative who is an alcoholic react more positively to alcohol than other people.

PHILADELPHIA -- A physician panel in the primary care specialty of internal medicine has identified common clinical activities where changes in practice could lead to higher quality care and better use of finite clinical resources.
The study identifying the Top 5 list of internal medicine activities appears online in the Archives of Internal Medicine.
Often, the goal of science is to show that things are not what they seem to be. But now, in an article which will be published in an upcoming issue of Perspectives on Psychological Science, a journal of the Association for Psychological Science, a veteran cognitive psychologist exhorts his colleagues in memory research to consult the truth of their own experience.
ST. PAUL, Minn. – African-Americans who have multiple sclerosis (MS) have lower vitamin D levels than African-Americans who don't have the disease, according to a study published in the May 24, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology. However, most of the difference in vitamin D levels was due to differences in climate and geography.
Men with chronic obstructive pulmonary disease (COPD) who are treated with inhaled anticholinergic drugs appear to have an increased risk of developing urinary retention (inability to urinate), according to a report in the May 23 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The article is part of the journal's Less Is More series.
Limiting antibiotic prescribing for certain respiratory infections, avoiding imaging for low back pain and osteoporosis screening for certain patients, and not ordering cardiac screening tests in low-risk patients are among the suggestions to make primary care more affordable and efficient, according to a report posted online today that will be published in the August 8 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The article is part of the journal's Less Is More series.
ATLANTA – May 23, 2011 – A new study from American Cancer Society researchers finds use of 30 tablets a month or more of acetaminophen for five or more years was associated with an estimated 38% lower risk of prostate cancer. The study appears in Cancer Epidemiology, Biomarkers and Prevention and is one of only two studies of prostate cancer to date that have examined the association with acetaminophen use that was both long-term and regular.
Researchers at the Johns Hopkins University School of Medicine have devised a new technique, which helps couples that are affected by or are carriers of genetic diseases have in vitro fertilized babies free of both the disease in question and other chromosomal abnormalities. The results were reported in the April issue of Fertility and Sterility.
A team led by Thomas B. Nutman, M.D., of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has completed a large-scale analysis of most of the proteins produced by Brugia malayi, one kind of parasitic worm that causes lymphatic filariasis, or elephantiasis. The greatly swollen lower limbs that can result from chronic infection with this mosquito-borne parasite can be severely disabling.
Using bacteria to generate energy is a signifiant step closer following a breakthrough discovery by scientists at the University of East Anglia (UEA).
Published today by the leading scientific journal Proceedings of the National Academy of Sciences (PNAS), the research demonstrates for the first time the exact molecular structure of the proteins which enable bacterial cells to transfer electrical charge.
Their device can be contained on a single chip and is simple and inexpensive to manufacture. "The idea would be that doctors could take a tiny drop of blood from patients and be able to run diagnostic tests on it right there in their office, instead of sending it away to a lab where testing can take days and is expensive," said Weihua Guan, a Yale engineering graduate student who led the project.
Researchers from Virginia Tech and Oxford University have proposed a novel molecular mechanism for the living cell's remarkable ability to detect the alignment of replicated chromosomes on the mitotic spindle in the final phase of the cell division cycle. This checkpoint mechanism prevents mistakes in the cell division process that could damage dividing cells and the organism they inhabit.
In a study to be published online this week in the Proceedings of the National Academy of Sciences, researchers report the discovery of a novel hepatitis C-like virus in dogs. The identification and characterization of this virus gives scientists new insights into how hepatitis C in humans may have evolved and provides scientists renewed hope to develop a model system to study how it causes disease.
Researchers at the Peter Munk Cardiac Centre discovered a protein switch which can trigger a cascade of events leading to heart failure, pointing to a new direction for drug development.
“Our research suggests that PINK1 is an important switch that sets off acascade of events affecting heart cell metabolism,” says Dr. Phyllis Billia,principal author, clinician‑scientist and heart failure specialist at thePeter Munk Cardiac Centre. “This could be one of the inciting events in thedevelopment of heart failure.”
(Santa Barbara, Calif.) –– Laboratory studies by chemical engineers at UC Santa Barbara may lead to new experimental methods for early detection and diagnosis –– and to possible treatments –– for pathological tissues that are precursors to multiple sclerosis and similar diseases.
