Ultrasound-Assisted Distal Radius Fracture Reduction.

Introduction Closed reduction of distal radius fractures (CRDRF) is a commonly performed emergency department (ED) procedure. The use of point-of-care ultrasound (PoCUS) to diagnose fractures and guide reduction has previously been described. The primary objective of this study was to determine if the addition of PoCUS to CRDRF changed the perception of successful initial reduction.

Detection and purification of glucose 6-phosphate dehydrogenase, malic enzyme, and NADP-dependent isocitrate dehydrogenase by blue native polyacrylamide gel electrophoresis.

We describe a blue native polyacrylamide gel electrophoretic technique that allows the facile detection, quantitation and purification of three NADPH-producing enzymes. Glucose 6-phosphate dehydrogenase, malic enzyme and NADP-dependent isocitrate dehydrogenase were detected simultaneously. Activity staining based on the formation of NADPH from the respective substrates and the subsequent precipitation of formazan enabled the relative quantitation of enzymatic activities, while Coomassie staining on one-dimensional or two-dimensional gels helped monitor the amount of protein associated with these enzymatic activities.
