Gut Development Studied Through Cannibal Tadpoles
Date: May-13-2013A carnivorous, cannibalistic tadpole may play a role in understanding the evolution and development of digestive organs, according to research from North Carolina State University. These findings may also shed light on universal rules of organ development that could lead to better diagnosis and prevention of intestinal birth defects. NC State developmental biologist Nanette Nascone-Yoder, graduate student Stephanie Bloom, and postdoctoral researcher Cris Ledon-Rettig looked at Xenopus laevis (African clawed frog) and Lepidobatrachus laevis (Budgett's frog) tadpoles...
Gene Expression Profiling In Breast Cancer
Date: May-13-2013Predicting outcomes for cancer patients based on tumor-immune system interactions is an emerging clinical approach, and new research from Wake Forest Baptist Medical Center is advancing the field when it comes to the most deadly types of breast cancer. "We know that one function of our immune system is to detect and destroy pre-malignant cells before they can become cancer," said lead author Lance D. Miller, Ph.D., associate professor of cancer biology at Wake Forest Baptist. "However, sometimes the immune system becomes unresponsive to the presence of these cells and a tumor develops...
Sexual Harassment Linked To Eating Disorder In Men
Date: May-12-2013Men who experience high levels of sexual harassment are much more likely than women to induce vomiting and take laxatives and diuretics in an attempt to control their weight, according to a surprising finding by Michigan State University researchers. Their study is one of the first to examine the effects of sexual harassment on body image and eating behaviors in both women and men...
Opportunity In Health Care System To Reach Out To Boys Contemplating Suicide
Date: May-12-2013More than 80 per cent of youth who die by suicide had some form of contact with the health care system in the year before their death, according to a new study from St. Michael's Hospital. "This suggests there are a lot of opportunities for prevention," said Dr. Anne Rhodes, a research scientist at the hospital's Suicide Studies Research Unit. "Most of these youth were seen by an outpatient physician or went to an emergency department where they could have potentially benefited from an intervention." Among those seen by an outpatient physician, half of young men and 67...
Children At Greatest Risk Of Cerebral Malaria Identified By New Malaria Tool
Date: May-12-2013Researchers at Michigan State University have identified a test that can determine which children with malaria are likely to develop cerebral malaria, a much more life-threatening form of the disease. The screening tool could be a game-changer in resource-limited rural health clinics where workers see hundreds of children with malaria each day and must decide which patients can be sent home with oral drugs and which need to be taken to hospitals for more comprehensive care...
New Inhaler Drug Approved By FDA For Chronic COPD
Date: May-12-2013The U.S. Food and Drug Administration has just announced the approval of a form of new long-term treatment for patients suffering from chronic obstructive pulmonary disease (COPD). The new treatment is an inhaler drug called Breo Ellipta (fluticasone furoate and vilanterol inhalation powder). It is also approved for the treatment of exacerbations in COPD patients. COPD is a form of lung disease that progressively gets worse, it is characterized by the occurrence of chronic bronchitis or emphysema (a pair of co-existing diseases that narrow the airways)...
Clinical Guide On Endometrial Assessment In Postmenopausal Women Published In Maturitas
Date: May-12-2013Elsevier, a world-leading provider of scientific, technical and medical information products and services, has announced the publication of a clinical guide by the European Menopause and Andropause Society (EMAS) in the journal Maturitas on endometrial assessment in peri and postmenopausal women with summary recommendations. The main onus of endometrial assessment is to exclude carcinoma of the endometrium and premalignant endometrial hyperplasia. Assessment of the endometrium in the absence of bleeding should be limited to women at high risk of endometrial cancer...
Engineers Develop More Sensitive Electronic Nose
Date: May-12-2013Swedish and Spanish engineers have created a system of sensors that detects fruit odours more effectively than the human sense of smell. For now, the device can distinguish between the odorous compounds emitted by pears and apples. Researchers from the Polytechnic University of Valencia (UPV, Spain) and the University of Gävle (Sweden) have created an electronic nose with 32 sensors that can identify the odours given off by chopped pears and apples...
Prostate Cancer Tool Tested By UC San Francisco Helps Identify Those Best Suited For Active Surveillance
Date: May-12-2013A new genomic test for prostate cancer can help predict whether men are more likely to harbor an aggressive form of the disease, according to a new UC San Francisco study. The test, which improves risk assessment when patients are first diagnosed, can also aid in determining which men are suitable for active surveillance - a way of managing the disease without direct treatment. Prostate cancer often grows slowly, and many of the quarter-million patients diagnosed annually in the United States never need treatment, which typically involves surgery, radiation or both...
Widespread PCB Pollution
Date: May-12-2013Since polychlorinated biphenyls (PCBs) are produced through industrial processes or activities, it is assumed that people living in industrial cities will have higher concentrations of these toxic chemicals in their blood than people in rural communities. Researchers at the University of Iowa say this isn't the case. In a paper published recently in the journal Environmental Science & Technology, scientists report that mothers and children in East Chicago, Ind., and Columbus Junction, Iowa, had only subtle differences in their PCB blood levels...
