Acupuncture has pain-relief effects, but no data were available on the use of transcutaneous electric acupoint stimulation (TEAS) in pain relief during oocyte retrieval. This study was designed to ...examine the effect of TEAS for pain relief in women undergoing transvaginal ultrasound-guided oocyte aspiration. This single-blinded, multicenter, randomized controlled trial was performed in China between May 2013 and May 2015. The subjects were randomized to mock TEAS and TEAS. TEAS or mock TEAS was administered 30 min before oocyte retrieval until the end of the operation. The primary and secondary endpoints were the pain measured using the visual analog scale (VAS) within 1 min and 1 hour after oocyte retrieval, respectively. Serum β-endorphin levels were tested in the first 50 patients/group. 390 women were undergoing oocyte retrieval. Pain levels evaluated using VAS within 1 min (18.6 ± 1.3 vs. 24.4 ± 1.7, P<0.01) and 1 h after oocyte aspiration (4.6 ± 0.7 vs. 6.8 ± 0.8, P<0.05) were lower in the TEAS group than in the mock TEAS group. Nausea assessment revealed a significantly lower VAS score in the TEAS group within 1 min (1.2 ± 0.4 vs. 2.9 ± 0.7, P<0.033). Serum β-endorphin levels were significantly higher in the TEAS group than in the mock TEAS group (11.4 ± 0.5 vs. 9.1 ± 0.4, P<0.001) after retrieval. Serum β-endorphin levels were higher in the TEAS group after the procedure than baseline (11.4 ± 0.5 vs. 9.1 ± 0.3, P<0.001). Oocyte retrieval causes pain and discomfort, but TEAS is effective and safe for suppressing the pain and alleviating nausea associated with the operation.

The size and shape of the plant leaf is an important agronomic trait. To understand the molecular mechanism governing plant leaf shape, we characterized a classic rice (Oryza sativa) dwarf mutant ...named narrow leaf1 (nal1), which exhibits a characteristic phenotype of narrow leaves. In accordance with reduced leaf blade width, leaves of nal1 contain a decreased number of longitudinal veins. Anatomical investigations revealed that the culms of nal1 also show a defective vascular system, in which the number and distribution pattern of vascular bundles are altered. Map-based cloning and genetic complementation analyses demonstrated that Nal1 encodes a plant-specific protein with unknown biochemical function. We provide evidence showing that Nal1 is richly expressed in vascular tissues and that mutation of this gene leads to significantly reduced polar auxin transport capacity. These results indicate that Nal1 affects polar auxin transport as well as the vascular patterns of rice plants and plays an important role in the control of lateral leaf growth.
Cluster-based servers delivering timely responsive service can shorten response latency and maximize system throughput through multi-threading. However, under high workload, large volume of threads ...may overload the kernel, leading to an inoperational system "hold-out" status. Majority of overload control work have been done at application level, but lack the collaboration between application and kernel to proactively respond to overloading. In this paper we propose two application-kernel cooperative mechanisms, of which the Flush-Out function recovers system from overloading by filtering out certain amount of events from kernel, and the Early-Drop mechanism protects system from overloading by proactively responding to load status. Experiments on a cluster server indicate the proposed mechanisms improve serverpsilas responsiveness under high load condition by substantially cutting the response time by 7~22% and event drop rate to 10~21%. The application-kernel mechanisms demonstrate its effectiveness in keeping mission-critical servers in operational state and delivering improved performance under high .workload.
