J. Y. CHOI, S. J. KIM, E. L. LEE. Change of Plantar Pressure Distribution of Open Stance during Forehand Stroke M Tennis. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 143-153, 2005. Recently among several tennis techniques forehand stroke has been greatly changed in the aspect of spin, grip and stance. The most fundamental factor among the three factors is the stance which consists of open, square and close stance and it is very important to know the patterns of plantar pressure distribution for the better understanding of forehand stroke. Therefore, the purpose of this study was to investigate the change of plantar pressure distribution in open stance during forehand stroke in tennis. Three high school tennis players were recruited for the study and required to perform forehand stroke five consecutive trials in the condition of open stance. The forehand strokes were filmed with two digital video cameras and measured with pedar system for plantar pressure. The plantar regions under the foot were divided into 3 regions, which were forefoot, midfoot, and rear foot. In conclusion, The plantar pressure of open stance during forehand stroke was distributed more largely to the right foot. The plantar pressure of open stance during forehand stroke was distributed more weight loads on forefoot of right than heel of right

This thesis proposes a new hardware allocation algorithm for design automation. The proposed algorithm works on scheduled input graph and simultaneously allocates binds functional units, interconnections and registers by considering interdependency between operations and storage elements in each control step, in order to share registers and interconnections connected to functional units, as much as possible. This thesis shows the effectiveness of the algorithm by comparing the results of our experiments with those of exiting system.

Objective To verify effects of rs1061622 at tumor necrosis factor-α receptor II (TNF-RII) gene (<i>TNF-RII</i>) on post-traumatic stress disorder (PTSD) and its interactive effects with PTSD on serum lipids levels in adolescents.Methods PTSD was measured by PTSD Checklist-Civilian Version (PCL-C) in 699 adolescent survivors at 6 months after Wenchuan earthquake in China. A polymerase chain reaction and restriction fragment length polymorphism assay were utilized for <i>TNF-RII</i> rs1061622 genotyping followed by verification using DNA sequencing. Serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol were tested using routine methods.Results G (deoxyguanine) allele carriers had higher PCL-C scores than TT (deoxythymidine) homozygotes in female subjects. Female adolescents had higher PCL-C scores than male subjects in TT homozygotes. Predictors of PTSD prevalence and severity were different between G allele carriers and TT homozygotes. Subjects with PTSD had lower TG, TG/HDL-C, TC/HDL-C, and higher HDL-C than adolescents without PTSD in male G allele carriers. G allele carriers had higher TG/HDL-C and TC/HDL-C than TT homozygotes in male adolescents without PTSD, and lower TG and TG/HDL-C in male PTSD patients. G allele carriers had higher TG than TT homozygotes only in female adolescents without PTSD.Conclusion These results suggest reciprocal actions of <i>TNF-RII</i> rs1061622 with other factors on PTSD severity, interplays of <i>TNF-RII</i> rs1061622 with PTSD on serum lipid levels, and novel treatment strategies for PTSD and comorbidities of PTSD with hyperlipidemia among adolescents with different genetic backgrounds of <i>TNF-RII</i> rs1061622 after experiencing traumatic events.

<P>We report the fabrication of a three-dimensional free-standing nitrogen-doped porous graphene/graphite foam by <I>in situ</I> activation of nitrogen-doped graphene on highly conductive graphite foam (GF). After <I>in situ</I> activation, intimate “sheet contact” was observed between the graphene sheets and the GF. The sheet contact produced by <I>in situ</I> activation is found to be superior to the “point contact” obtained by the traditional drop-casting method and facilitates electron transfer. Due to the intimate contact as well as the use of an ultralight GF current collector, the composite electrode delivers a gravimetric capacity of 642 mAh g<SUP>–1</SUP> and a volumetric capacity of 602 mAh cm<SUP>–3</SUP> with respect to the whole electrode mass and volume (including the active materials and the GF current collector). When normalized based on the mass of the active material, the composite electrode delivers a high specific capacity of up to 1687 mAh g<SUP>–1</SUP>, which is superior to that of most graphene-based electrodes. Also, after ∼90 s charging, the anode delivers a capacity of about 100 mAh g<SUP>–1</SUP> (with respect to the total mass of the electrode), indicating its potential use in high-rate lithium-ion batteries.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2015/ancac3.2015.9.issue-8/acsnano.5b03888/production/images/medium/nn-2015-03888k_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn5b03888'>ACS Electronic Supporting Info</A></P>

TIM-1 (also known as KIM-1 and HAVcr-1) is a type I transmembrane glycoprotein member of the TIM family that may play important roles in innate and adaptive immune responses. The overexpression of proteins associated with membrane proteins is a major obstacle to overcome in studies of membrane protein structures and functions. In this study, we successfully coupled the overexpression of the TIM-1 protein with a C-terminal enhanced green fluorescent protein (GFP) tag in Escherichia coli. To the best of our knowledge, this report is the first to describe the overexpression of human TIM-1 in E. coli. The purified TIM-1-EGFP fusion protein recognized and bound directly to apoptotic cells and did not to bind to viable cells. Furthermore, we confirmed that the interactions of TIM-1-EGFP with apoptotic cells were blocked by TIM-1-Fc fusion proteins. This fusion protein represents a readily obtainable source of biologically active TIM-1 that may prove useful in future studies of human TIM-1.

Most physiologicalstudies studies of oat beta(β)-glucan have shown positive effects on regulation ofblood glucose and lipid metabolism related to β-glucanmetabolism in the gastrointestinal tract. The effects of oatβ-glucan (OG), oat bran (OB), oat flour (OF), and oatmeal(OM) containing different levels of β-glucan on digestibilityand degradation were investigated in normal mice. Chymeviscosity, the gastric emptying rate, the gastrointestinaltransit rate, the activities of intestinal digestive enzymes,the levels of plasma cholecystokinin (CCK) and motlin(MOT), and degradation of β-glucan in oat products weredetermined. β-glucans from different oat products increasedintestinal chyme viscosity, delayed gastric emptying,promoted enterokinesia, decreased amylase, trypsin, lipase,and Na+, K+-ATPase activities, and promoted secretion ofCCK and MOT, especially for oat derived β-glucan.
