Winner doesn't always take all Theoretically predicted and now demonstrated experimentally for the first time using soil bacteria: weaker organisms can prevail against stronger ones -- if they are superior in number. This acts as a driving mechanism in the maintenance of genetic diversity, scientists report.
Gene modulation method may provide insight on regrowing inner-ear sensory hair cells An expert in the biology and physiology of the inner ear has developed a method to temporally modify the expression of the retinoblastoma-1 gene in mice. Modulation of the RB1 gene can allow for the regrowth of cells in the inner ear and potentially restore hearing and balance caused by the loss of sensory hair cells.
Vitamin D shows promise for treating Crohn's disease New research suggests that supplementation with vitamin D may impact on the intestinal barrier dysfunction associated with Crohn's disease, and could have a role in the treatment of the condition.
How to manage pain in the ER: Ask the patient Simply asking the question, 'Do you want more pain medication?' resulted in satisfactory pain control in 99 percent of emergency department patients participating in a study of a new evidence-based protocol to treat acute, severe pain in emergency department patients.
Study may help to find vets with high-risk of suicide Veterans Affairs health data has been used to identify very small groups of patients with very high, predicted suicide risk -- most of the individuals had not been identified for suicide risk by clinicians. Such methods can help the Veterans Health Administration to target suicide prevention efforts for patients at high risk, and may have more wide-ranging benefits.
