BALTIMORE – March 19, 2013. Researchers at the University of Maryland School of Medicine have identified a peptide, or protein, derived from Pacific cod that may inhibit prostate cancer and possibly other cancers from spreading, according to preclinical research published online in the Proceedings of the National Academy of Sciences (PNAS).

New Rochelle, NY, Mar 19, 2013—Chronic fatigue, a persistent lack of energy that does not improve with rest, is at least three times more prevalent among adult survivors of acute lymphoblastic leukemia and lymphoma experienced during childhood or adolescence than in the general adult population, according to an article in Journal of Adolescent and Young Adult Oncology (JAYAO), (http://www.liebertpub.com/JAYAO) a multidisciplinary peer-reviewed publication from Mary Ann Liebert, Inc., publishers.

Screening for breast cancer every two years appears just as beneficial as yearly mammograms for women ages 50 to 74, with significantly fewer "false positives" – even for women whose breasts are dense or who use hormone therapy for menopause.

That is the finding of a new national study involving more than 900,000 women.

The study was published on March 18 in JAMA Internal Medicine.

The same team of researchers from UC San Francisco and Seattle-based Group Health Research Institute recently reported similar results for older women ages 66 to 89 years old.

PHILADELPHIA — The overexpression or underexpression of a newly identified set of genes related to lipid metabolism may help physicians identify whether or not a woman is at risk for hormone receptor-positive or hormone receptor-negative breast cancer and to subsequently tailor prevention strategies appropriately, according to data published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

CHICAGO --- A newly identified set of genes may predict which women are at high risk for getting breast cancer that is sensitive to estrogen and, therefore, would be helped by taking drugs to prevent it, reports a new Northwestern Medicine study.

Making headway against a major public health threat, Dartmouth College researchers have invented the first ever secondhand tobacco smoke sensor that records data in real time, a new study in the journal Nicotine and Tobacco Research shows.

UCLA researchers have genetically engineered tomatoes to produce a peptide that mimics the actions of good cholesterol when consumed.

Published in the April issue of the Journal of Lipid Research and featured on the cover, their early study found that mice that were fed these tomatoes in freeze-dried, ground form had less inflammation and plaque build-up in their arteries.

BUFFALO, N.Y. – Consumption of foods high in carbohydrates immediately after birth programs individuals for lifelong increased weight gain and obesity, a University at Buffalo animal study has found, even if caloric intake is restricted in adulthood for a period of time.

The research on laboratory animals was published this month in the American Journal of Physiology: Endocrinology and Metabolism; it was published online in December.

Parasitoid wasps of the family Braconidae are known for their deadly reproductive habits. Most of the representatives of this group have their eggs developing in other insects and their larvae, eventually killing the respective host, or in some cases immobilizing it or causing its sterility.

A study published in the March issue of Hepatology, a journal of the American Association for the Study of Liver Diseases, estimates that the prevalence of acute hepatitis C virus (HCV) infection is nearly one percent among newly incarcerated inmates with a history of recent drug use. Findings suggest that systematic screening of intravenous (IV) drug users who are new to the prison system could identify more than 7,000 cases of HCV across the U.S. annually—even among asymptomatic inmates.

Teen-age college students are significantly more likely to abstain from drinking or to drink only minimally when their parents talk to them before they start college, using suggestions in a parent handbook developed by Robert Turrisi, professor of biobehavioral health, Penn State.

AMHERST, Mass. – When researchers at the University of Massachusetts Amherst led by microbiologist Derek Lovley discovered that the bacterium Geobacter sulfurreducens conducts electricity very effectively along metallic-like "microbial nanowires," they found physicists quite comfortable with the idea of such a novel biological electron transfer mechanism, but not biologists.

Individuals infected by the hepatitis C virus (HCV) have nothing to fear from sex in a monogamous, heterosexual relationship. Transmission of HCV from an infected partner during sex is rare according to new research published in the March issue of Hepatology, a journal published by Wiley on behalf of the American Association for the Study of Liver Diseases (AASLD).

Psychologists have traditionally characterized compulsive gambling as an "impulse control disorder," and treated it by addressing the patient's obsessive tendencies. But according to Prof. Pinhas Dannon of Tel Aviv University's Sackler Faculty of Medicine and the Beer Yaakov Mental Health Center, not all pathological gamblers fit the same profile.

Daphnia is a genus of small, planktonic crustaceans, commonly called 'water fleas' because of their jumpy swimming style and their size (between 0.2 and 5 mm). They live in various aquatic environments, ranging from acidic swamps to freshwater lakes, ponds, streams and rivers.
