Philadelphia, PA, July 18, 2013 – Cancer researchers have wondered why ovarian cancer cells are so attracted to the abdominal cavity, especially the omentum, with the hope that such an understanding could lead to better disease management or even prevention. Results from a series of experiments suggest a two-step model of omental colonization in which i) cancer cells are attracted to and lodge within immune cell-containing structures known as milky spots, and ii) fat storage cells (adipocytes) fuel cancer cell growth and spread.

[EMBARGOED FOR JULY 18, 2013] Facebook posts helped alert public health officials to a strep throat outbreak among a high school dance team in 2012, and DNA fingerprinting led investigators to pasta prepared by a previously ill parent as the likely source. Although strep throat, or Group A Streptococcus (GAS) pharyngitis, usually spreads from person to person by droplets, foodborne transmission is possible, as a report published online in Clinical Infectious Diseases found. The most common form of GAS illness is strep throat, but some cases can have more severe consequences.

Stricter controls over bumblebee imports to the UK are urgently required to prevent diseases spreading to native bumblebees and honeybees, scientists have warned. The call follows the discovery of parasites in over three-quarters of imported bumblebee colonies they tested. The study - the first of its kind in the UK - is published today in the Journal of Applied Ecology.

Recent changes in hockey rules regulating contact to the head have not reduced the number of concussions suffered by players during National Hockey League (NHL) season, according to research published July 17 in the open access journal PLOS ONE by Michael Cusimano and colleagues from the Injury Prevention Research Office at St. Michael's Hospital, Canada.

Some of the largest herbivorous dinosaurs replaced their teeth at a rate of approximately one tooth every 1-2 months to compensate for tooth wear from crunching up plants, according to research published July 17 in the open access journal PLOS ONE by Michael D'Emic from Stony Brook University and colleagues from other institutions.

NEW YORK, NY (July 17, 2013) — Researchers at Columbia University Medical Center (CUMC) and collaborators have identified a genetic mutation that causes congenital malformations of the kidney and urinary tract, a common form of birth defect and the most common cause of kidney failure in children. It is the first time that a specific genetic mutation has been linked to a non-syndromic form of urinary tract malformation. The findings were published in the July 17 online issue of the New England Journal of Medicine.

SAN ANTONIO (July 17, 2013) — Molecular biologists in the School of Medicine at The University of Texas Health Science Center San Antonio have found a novel way to fine-tune the activity of cells' protein-disposing machinery, with potentially cancer-fighting effects.

In patients with high-risk breast cancer, addition of the erythropoiesis-stimulating agent (ESA) epoetin alfa to the chemotherapy regimen may help avoid the decrease in hemoglobin levels and resulting anemia often seen in these patients and does not negatively affect relapse-free (RFS) or overall survival (OS). However, it can increase the risk of thrombotic events, according to a study published July 17 in the Journal of the National Cancer Institute.

SCOTTSDALE, Ariz. — July 17, 2013 — The Side-Out Foundation's breast cancer pilot study, led by the Translational Genomics Research Institute (TGen), Translational Drug Development (TD2) and Scottsdale Healthcare, has shown that cancer patients do better when their treatment is guided by molecular profiling.

A Johns Hopkins study finds that healthy people who carry a genetic mutation for arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) are at much higher risk of developing the symptoms of the life-threatening heart disease if they participate in endurance sports and frequent exercise. The study also suggests that those carriers who significantly cut back on their exercise regimen may reduce their risk or delay the onset of symptoms.

An article on the study results is published online July 17, 2013, in the Journal of the American College of Cardiology.

Irvine, Calif., July 17, 2013 — UC Irvine microbiologists have learned how a probiotic bacterium used to treat irritable bowel syndrome can soothe gut bacterial infections caused by Salmonella, paving the way for potential relief from foodborne illnesses that affect millions of people annually.

PROVIDENCE, R.I. [Brown University] — Engineers from Brown University have mapped out the amounts of compression required to cause wrinkles, creases, and folds to form in rubbery materials. The findings could help engineers control the formation of these structures, which can be useful in designing nanostructured materials for flexible electronic devices or surfaces that require variable adhesion.

CHICAGO – Certain aspects of an individual's personality may be a determining factor in whether they like their food plain and bland or spicy and hot, according to research presented at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Food Expo®.

CHICAGO— Creating and promoting foods that contain natural inhibitors of unhealthy angiogenesis – the formation of blood vessels that feed and promote disease, obesity and inflammation – is the "new frontier in dietary health," according to a presentation at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Food Expo® in Chicago.

DURHAM, N.C. -- Physicians and patients who are wary of addiction to pain medication and opioids may soon have a healthier and more natural alternative.

A Duke University study revealed that a derivative of DHA (docosahexaenoic acid), a main ingredient of over-the-counter fish oil supplements, can sooth and prevent neuropathic pain caused by injuries to the sensory system. The results appear online in the Annals of Neurology.
