The ST131 strain of E. coli is a major cause of serious antimicrobial-resistant infections in the US, accounting for 67-69% of resistant isolates. Researchers urge discovering its sources to prevent further spread.
Research found that proton pump inhibitors (PPIs) are a risk factor for Clostridium difficile-associated diarrhea (CDAD) recurrence. The study, published in the World Journal of Gastroenterology, identified age, low serum albumin levels, and PPI use as risk factors for CDAD recurrence.
JILA's technique uses infrared laser light to quickly and precisely heat 'nano bathtubs'—tiny sample containers—for microscopy studies of single molecules and nanoparticles. The new method enables fast, noncontact heating of very small samples, enabling new experiments with single molecules.
Researchers found that epigenetic profiles of tumors had a direct association with diet, alcohol, and tumor size, providing new biomarkers for disease subtype and severity. The study's data show promise for tumor epigenetic signatures to provide more detailed tumor staging and prediction of prognosis.
A 3-year study found no significant positive effect of soy isoflavones on preventing bone loss in postmenopausal women. However, a moderate dose of 120mg showed a modest benefit when combined with lifestyle factors.
DZNE and LMU researchers have identified alpha secretase enzyme ADAM10, which cleaves amyloid precursor protein without forming beta-amyloid plaques. This discovery opens up new possibilities for diagnosing and preventing Alzheimer's disease.
A recent study found that transforaminal steroid injection is a viable alternative to surgery for lumbar radicular pain due to disc herniation, with 54% of patients achieving pain relief after 1 month. The treatment was shown to be more effective than other methods, including local anesthesia and saline injections.
