上海大学学报（自然科学版） 2004年第B10期10卷 25-28页

There are two different methods for coronary artery bypass grafting: end-to-side and side-to-side anastomosis. In vitro mock test, flow visualization and animal experiments were performed in parallel to compare the hemodynamic effect between two methods. Thus, bioengineers can provide practical useful information to the clinical team.

为了估测肉牛怀孕期的能量需要,利用日本黑牛作了一系列的试验。试验从头胎产前开始,延续到第四产。每一试验用六头牛。怀孕青年牛或母牛分为三组,喂以三个水平的试验饲粮,即,(1)生长或维持,(2)生长(或维持)+怀孕,(3)生长(或维持)+2×怀孕需要量(日本饲养标准1975)。利用能量代谢试验所得资料,以因子与复回归公式法作了估计。由此得出用于胎儿生长的代谢能利用效率为14.9％,母牛在怀孕期维持能量需

An important factor in the emergence and progre sion of osteosarcoma(OS)is the dysregulated expression of microRNAs(miRNAs).Transcription factor 7-like 1(TCF7LI),a member of the T cell factor/lymphoid enhancer factor(TCF/LEF)transcription factor family,interacts with the Wnt signaling pathway regulator β-catenin and acts as a DNA-specific binding *** study sought to elucidate the impact of the interaction between miR 3293p and TCF7L1 *** growth and apoptosis of OS and analyze the regulatory expression relationship between miRNA and mRNA in osteosarcoma cells using a variety of ***329-3p was significantly downregulated,while TCF7L1 was considerably up-regulated in all examined OS cell ***,a clinical comparison study was performed using the TCGA ***,the regulatory relationship between miR-329-3p and TCF7L1 on the proliferation and apoptosis of OS cells was verified through in vitro and in vivo *** miR 329-3p was transfected into the OS cell line,the expression of TCF7L1 decreased,the proliferation of OS cells was inhibited,the cytoskeleton disintegrated,and the nucleus condensed to fom apoptotic *** expression of proteins that indicate apoptosis increased *** cell cycle was arrested in the G0/G1 phase,and the G1/S transition was *** introduction of miR 3293p also inhibited downstream Cyclin D1 of the Wnt *** experiments indicated that the overexpression of miR-329-3p signi ficanly inhibited the growth of OS xenografts in nude mice,and the expression of TCF7L1 and C-Myc in tumor tssues *** 329-3p was significantly reduced in OS cells and played a suppressive role in tumorigenesis and proliferation by targeting TCF7L1 both in vitro and in *** cell cycle arrest and pathway inhibition were observed upon the regulation of TCF7LI by miR *** these results,it can be inferred that miR.3293p exerts anticancer efects in osteosarcom

Aqueous-phase reforming(APR)is an attractive process to produce bio-based hydrogen from waste biomass streams,during which the catalyst stability is often challenged due to the harsh reaction *** this work,three Pt-based catalysts supported on C,AlO(OH),and ZrO_(2)were investigated for the APR of hydroxyacetone solution in afixed bed reactor at 225℃and 35 *** them,the Pt/C catalyst showed the highest turnover frequency for H_(2)production(TOF of 8.9 molH_(2)molPt^(-1)min^(-1))and the longest catalyst *** the AlO(OH)and ZrO_(2)supported Pt catalysts,the side reactions consuming H_(2),formation of coke,and Pt sintering result in a low H_(2)production and the fast catalyst *** proposed reaction pathways suggest that a promising APR catalyst should reform all oxygenates in the aqueous phase,minimize the hydrogenation of the oxygenates,maximize the WGS reaction,and inhibit the condensation and coking reactions for maximizing the hydrogen yield and a stable catalytic performance.
