3Preparation and characterization of some surface negatively charged residue mutants of cytochrome b_5显示文摘Site-directed mutagenesis was used to obtain seven variants of tryptic fragment of bovine liver cytochrome bs (cyt bs), in which the negatively charged residues around the heme exposed edge of cyt bs were replaced by hydropho-bic amino acid alanine. Double-site mutants, triple-site mutants and even quadruple-site mutants were obtained. DNA sequencing and molecular weight measurements of the mutant proteins both confirmed that these site-directed muta-genesises were successfully performed. Spectroelectrochem-istry of these mutant proteins revealed that the apparent redox potentials of these mutant proteins caused a positive shift of 2-10 mV. The global structure of these mutant proteins did not show much difference from that of the wild type cyt bs, providing a solid base for the further study on the roles of the proteins’ surface charges.WANG Yunhua, WANG Wenhu, LU Junxia, REN Yi, GU Shaohua, XIE Yi & HUANG Zhongxian1.

9Adaptive deinterlacing algorithm based on motion compensation显示文摘An adaptive deinterlacing algorithm based on motion compensation is presented. It consists of the detection of motion blocks, the adaptive motion estimation with Kalman filtering, and the motion compensation for motion blocks and field repetition for static blocks. The detection of motion blocks can accurately identify the motion blocks by using successive 4field images. The motion estimation module with Kalman filtering searches motion vectors only for motion blocks, and the search model is adaptive to motion velocity and acceleration. Two deinterlacing methods are adopted to satisfy the different requirements of motion blocks and static blocks. Compared with full search algorithm, the proposed algorithm greatly reduces the computational amount while keeping the performance approximately.Gao Xinbo Gu Junxia 2005Journal of Systems Engineering and Electronics2005,16,4:0
10Effect of vanadium on the microstructure and properties of metastable austenitic stainless steel AISI 301LN显示文摘In this study,the effect of vanadium on the microstructure and properties of the metastable austenitic stainless steel AISI 301LN was investigated.Results of the study show that the addition of vanadium can refine grains and increase the strength of AISI 301LN by solution treatment.After 60%cold-rolling reduction,the microstructure of the steel was composed of work-hardened austenite bands and deformation-inducedɑ′martensite.Considerable work-hardening and phase transformation strengthening occurred.After cold rolling and subsequent annealing,the deformation-inducedɑ′martensite was reversed into fine-grained austenite.The work-hardened austenite bands underwent recrystallization;however,the structure of the recrystallized austenite grains was coarser than that of the reversed ones.Simultaneously,the strength of the experimental steels decreased with the increase in annealing temperature.The pinning effect of precipitates of vanadium inhibited the growth of austenite grains.Thus,the desirable combination of strength and ductility was obtained by grain refinement.HUANG Junxia GU Jiaqing 2021Baosteel Technical Research2021,15,2:0
11Effect of the cold deformation regime on microstructure and mechanical properties of AISI 301LN stainless steel显示文摘This study analyzed the effect of cold-rolling reduction(in a wide range of 10%-80%) and subsequent annealing on the microstructure and mechanical properties of AISI 301 LN stainless steel.Results indicated the formation of shear bands and nucleation of strain-induced α'-martensite at their intersections.The volume fraction of α'-martensite increased with increase in cold-rolling reduction by the continuous growth of embryos.This,in turn,resulted in an increase in yield and tensile strengths.The reversion of α'-martensite to austenite occurred after subsequent annealing.The observed variation in the grain size of reversed austenite can be related to the annealing regime.A good combination of strength and ductility can be obtained upon annealing at 650℃ for 30 min.The effect of grain size on yield strength conformed to the Hall-Petch relationship in the entire range of our analysis.HUANG Junxia YE Xiaoning GU Jiaqing 2014Baosteel Technical Research2014,8,3:0
12Transcriptome Analysis of Schwann Cells at Various Stages of Myelination Implicates Chromatin Regulator Sin3A in Control of Myelination Identity显示文摘Enhancing remyelination after injury is of utmost importance for optimizing the recovery of nerve function.While the formation of myelin by Schwann cells(SCs)is critical for the function of the peripheral nervous system,the temporal dynamics and regulatory mechanisms that control the progress of the s lineage through myelination require further elucidation.Here,using in vitro co-culture models,gene expression profiling of laser capture-microdissected SCs at various stages of myelination,and multilevel bioinformatic analysis,we demonstrated that SCs exhibit three distinct transcriptional characteristics duringmyelination:the immature,promyelinating,and myelinating states.We showed that suppressor interacting 3a(Sin3A)and 16 other transcription factors and chromatin regulators play important roles in the progress of myelination.Sin3A knockdown in the sciatic nerve or specifically in SCs reduced or delayed the myelination of regenerating axons in a rat crushed sciatic nerve model,while overexpression of Sin3A greatly promoted the remyelination of axons.Further,in vitro experiments revealed that Sin3A silencing inhibited SC migration and differentiation at the promyelination stage and promoted SC proliferation at the immature stage.In addition,SC differentiation and maturation may be regulated by the Sin3A/histone deacetylase2(HDAC2)complex functionally cooperating with Sox10,as demonstrated by rescue assays.Together,these results complement the recent genome and proteome analyses of SCs during peripheral nerve myelin formation.The results also reveal a key role of Sin3A-dependent chromatin organization in promoting myelinogenic programs and SC differentiation to control peripheral myelination and repair.These findings may inform new treatments for enhancing remyelination and nerveregeneration.Bin Zhang Wenfeng Su Junxia Hu Jinghui Xu Parizat Askar Shuangxi Bao Songlin Zhou Gang Chen Yun Gu 2022Neuroscience Bulletin2022,38,7:0
