BACKGROUND The aim of this study was to compare the efficacy of axillary brachial plexus block using an ultrasound-guided method with the nerve stimulator-guided method. We also compared the efficacy of ultrasound-guided single-injection with those of double-injection for the quality of the block. METHODS Ninety patients scheduled for surgery of the forearm or hand were randomly allocated int...

RNA interference (RNAi) is a powerful strategy for gene function study in insects. Here, we described the development of a RNAi technique by microinjection of double-stranded RNA (dsRNA) in the brown planthopper Nilaparvata lugens. Based on the mortality and RNAi efficiency criteria, the conjunctive between prothorax and mesothorax was selected as the injection site and 50 nl as injection volum...

BACKGROUND We conducted prospective, randomized, observer-blinded trial to compare two double-injection perivascular (PV) ultrasound-guided techniques of axillary brachial plexus block (BPB). METHODS American Society of Anesthesiologists physical status I-II, 50 patients undergoing surgery of the forearm, wrist or hand were randomly allocated to two groups. For PV12 group, injection was carri...

Methods: Two experiments were conducted. In experiment 1, sows received one of two treatments: either a single IM injection of 175 μg cloprostenol at day 113 of gestation (n=49) or an IM injection of 175 μg cloprostenol at day 113 of gestation followed by second IM injection of 175 μg cloprostenol 6 hours later (n=54). In experiment 2, sows received either a single (n=59) or a double (n=48) clo...

Critical limb ischemia (CLI) is one of the most severe forms of peripheral artery diseases, but current treatment strategies do not guarantee complete recovery of vascular blood flow or reduce the risk of mortality. Recently, human bone marrow derived mesenchymal stem cells (MSCs) have been reported to have a paracrine influence on angiogenesis in several ischemic diseases. However, little evid...

GaAs-GaAlAs double-heterostructure distributed-feedback injection lasers are investigated a t temperatures between 80 and 150 K under pulsed operation. The optical feedback for laser oscillation is provided by a corrugated interface between the p-GaAs active layer and the pGaA1As layer. The corrugation is made by two methods, ion milling and chemical etching, and the latter method is found to g...
