High Power Laser Science and Engineering 2017年第4期5卷 14-19页

With European Laser Facilities such as the Extreme Light Infrastructure(ELI) and the Helmholtz International Beamline for Extreme Fields(HIBEF) scheduled to come online within the next couple of years, General Atomics, as a major supplier of targets and target components for the High Energy Density Physics community in the United States, is gearing up to meet their demand for large numbers of low cost targets. Using the production of a subassembly for the National Ignition Facility's fusion targets as an example, we demonstrate that through automation of assembly tasks, the design of targets and their experimental setup can be fairly complex while keeping the assembly time and cost as a minimum.A six-axis Mitsubishi robot is used in combination with vision feedback and a force–torque sensor to assemble target subassemblies of different scales and designs with minimal change of tooling, allowing for design flexibility and short assembly setup times. Implementing automated measurement routines on a Nikon NEXIV microscope further reduces the effort required for target metrology, while electronic data collection and transfer complete a streamlined target production operation that can be adapted to a large variety of target designs.

通过精浆免疫抑制可逆性实验,精浆对淋巴细胞表面蛋白影响:白细胞趋化运动及巨噬细胞吞噬等试验,研究短时间与人精浆接触对人淋巴细胞和巨噬细胞的生物合成和免疫功能的影响。结果表明人精浆有不可逆影响活化淋巴细胞合成DNA;RNA和蛋白的能力,但不影响细胞表面蛋白的表达。提示人精液中的淋巴细胞已受精浆中某些物质所麻痹。然而人精浆并不影响巨噬细胞的吞噬功能,通过人精浆中的某些趋化因子可将巨噬细胞吸引到有精浆的部位。

Caregiver burden is increased in Parkinson’s disease with mild cognitive impairment (PD-MCI)

Background & Objectie:Sulfation of steroid hormones renders them receptor-inactive. Sulfotransferases (SULTs) catalyze the reaction with 3’-phosphoadenosine-5’-phosphosulfate(PAPS) as the sulfuryl moiety donor. Tibolone is a unique steroid that improves cliimacteric symptoms and prevents postmenopausal osteoporosis. It is the first in the STEAR class of compounds (Selective Tissue Estrogenic Activity Regulator). The active metabolites 3α-hydroxytibolone (3α-OHT)and 3β-hydroxytibolone (3β-OHT) undergo sulfation. Our objective was to characterize the human liver SULT activities involved in the sulfation of tibolone metabolites. Methods A pool of human liver cytosol

Peroneal tendon and retinacular pathology contributes to chronic lateral ankle instability. The “gold standard” surgical treatment for chronic lateral ankle instability has been the Brostrom-Gould procedure with its modifications. An ankle arthroscopy is an adjuvant procedure to address any intra-articular pathology. We review our results of two study groups. The first group underwent an ankle arthroscopy and a Brostrom-Gould procedure. The second group (triad) underwent an ankle arthroscopy, the Brostrom-Gould procedure and excision of low lying peroneal muscle belly with tightening of the inferior peroneal retinaculum. The triad technique was performed on 97 patients and results compared to 71 ankle arthroscopies with the Brostrom-Gould procedure. The patients were contacted at a mean follow-up time of 30 months for postoperative ACFAS scores, VAS scores, and overall satisfaction. Patients were also asked to report incidence of ankle sprain recurrence. The average postoperative ACFAS hindfoot and ankle score was 92 for the triad group and 89 for the arthroscopic debridement and Brostrom-Gould group. The average overall satisfaction was 98% in the triad group and 91% in the scope and Brostrom group. There were 4 (4.3%) recurrences in the triad group and 12 (17.6%) in the Brostrom-Gould with scope group. Each group had a similar incidence of wound healing complications. Peroneal tendon and retinacular pathology contributes to continued ankle instability and pain. We believe that the triad procedure is superior to the Brostrom-Gould procedure.
