CHICAGO – Researchers in London say they have found an effective two-part treatment for microtears in the hamstring: injections of the patient's own blood and a steroid along with "dry-needling," in which repeated needle punctures cause controlled internal bleeding in the injured area. Results of the study were presented today at the annual meeting of the Radiological Society of North America (RSNA).

CHICAGO – For years, it was believed that obese women were at lower risk for developing osteoporosis, and that excess body fat actually protected against bone loss. However, a study presented today at the annual meeting of the Radiological Society of North America (RSNA) found that having too much internal abdominal fat may, in fact, have a damaging effect on bone health.
Obesity is highly heritable, but so far genetic association studies have only explained a small fraction of this heritability. Now, in a study published in BioMed Central's open access journal Genome Biology, researchers have identified DNA variants in two nervous system genes that are associated with an excessively high BMI.
A new drug called FG-2216 can stimulate production of the hormone erythropoietin (EPO) in dialysis patients—possibly offering a new approach to treatment of kidney disease-related anemia, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).
Through an innovative use of cell phone records, researchers at UCLA, the University of Miami and Cal State, Fullerton, have found that women appear to avoid contact with their fathers during ovulation.
"Women call their dads less frequently on these high-fertility days and they hang up with them sooner if their dads initiate a call," said Martie Haselton, a UCLA associate professor of communication in whose lab the research was conducted.
DURHAM, N.C. -- Humans are known to play it safe in a situation when they aren't sure of the odds, or don't have confidence in their judgments. We don't like to choose the unknown.
And new evidence from a Duke University study is showing that chimpanzees and bonobos, our closest living primate relatives, treat the problem the same way we do.
In studies conducted at the Tchimpounga Chimpanzee Sanctuary in Republic of Congo and Lola ya Bonobo Sanctuary in Democratic Republic of Congo, researchers found the apes prefer to play it safe when the odds are uncertain.
Celecoxib may help prevent nonmelanoma skin cancers in patients with extensive actinic keratosis, which is often a precursor to these cancers, according to a randomized clinical trial published online November 29 in The Journal of the National Cancer Institute.
CORAL GABLES, FL (December 7, 2010)— Previous research has shown that when women are in their most fertile phase they become more attracted to certain qualities such as manly faces, masculine voices and competitive abilities. A new study by University of Miami (UM) Psychologist Debra Lieberman and her collaborators offers new insight into female sexuality by showing that women also avoid certain traits when they are fertile.
URBANA – The University of Illinois scientists who linked eating tomatoes with a reduced risk of prostate cancer have developed a tool that will help them trace the metabolism of tomato carotenoids in the human body. And they've secured funding from the National Institutes of Health to do it.
"Scientists believe that carotenoids—the pigments that give the red, yellow, and orange colors to some fruits and vegetables—provide the cancer-preventive benefits in tomatoes, but we don't know exactly how it happens," said John W. Erdman, a U of I professor of human nutrition.
A new study by researchers at the Walter and Eliza Hall Institute in Melbourne, Australia, has shown that mature blood cells can communicate with, and influence the behaviour of, their stem cell 'parents'.
CAMBRIDGE, Mass. (November 29, 2010) – Whitehead Institute researchers have shown in mouse models that overexpression of the microRNA 125b (miR-125b) can independently cause leukemia and accelerate the disease's progression. Their results are published in this week's online edition of the Proceedings of the National Academy of Sciences (PNAS).
PITTSBURGH, Nov. 29 – Breast cancers that arise sporadically, rather than through inheritance of certain genes, likely start with defects of DNA repair mechanisms that allow environmentally triggered mutations to accumulate, according to researchers at the University of Pittsburgh School of Medicine, Magee-Womens Hospital of UPMC and the University of Pittsburgh Cancer Institute.
ROCHESTER, Minn. - A team of Mayo Clinic researchers has found that patients with broken heart syndrome, also known as apical ballooning syndrome (ABS), have blood vessels that don't react normally to stress. These results offer clues to the cause of this rare syndrome and may help with efforts to identify patients who are more vulnerable to mental stress so that appropriate therapies can be developed. The study is published online in the Journal of the American College of Cardiology.
Can a road-trip across eastern North America, ancient ice sheets, and DNA samples unlock the ancestral history of jack pine trees? Julie Godbout and colleagues from the Université Laval, Quebec, Canada, certainly hoped that driving across northeastern U.S. and Canada to collect samples from jack pine trees would shed some light on how glaciers may have impacted present-day pine genetics.
