背景:胞质雄性不育(CMS)是由于线粒体基因组突变导致无功能性花粉产生的一种现象。对CMS和非CMS线粒体基因组的比较分析,揭示线粒体基因组间结构差异及因重组导致的广泛性重排具有重要意义。然而,在辣椒中与CMS相关的线粒体基因组结构及DNA重排机制仍不清楚。结果:获得了辣椒CMS FS4401(507 452 bp)和可育系Jeju(511 530 bp)线粒体完全基因组序列。并对辣椒、烟草线粒体基因组进行了比较分析,发现其均存在广泛的DNA重排和低保守性的非编码DNA区。FS4401和Jeju线粒体基因组比较发现,除了FS4401线粒体基因组中多了一个atp6(ψatp6-2)基因拷贝外,线粒体所有蛋白编码基因都一致。在基因组结构方面,发现两个线粒体基因组上的18个同线性序列区在基因组上存在重排,这些同线性序列区之间的序列总长度分别为30 380(FS4401)和17 847 bp(Jeju)。此前报道的CMS候选基因、orf507和ψatp6-2均位于FS4401最大特异序列片段的边界,在此区间大量的短序列片段聚集在一起,而Jeju中这些短序列表现为缺失或存在于不同的位点。连接序列片段的重复序列和重叠序列(由少数几个核苷酸组成)暗示同源重组导致的广泛性重排可能涉及到该区段的序列进化。本研究还利用其他植物种类的线粒体DNA序列进行分析,揭示CMS相关基因DNA区段的共同特征。结论:辣椒CMS和雄性可育系线粒体基因组大部分序列表现出一致性,但存在大量的基因组重排现象。辣椒CMS候选基因位于高度重排的CMS特定DNA区域的边界或重复序列附近。通过对其他物种CMS相关基因的特征分析,揭示出可能涉及到CMS相关基因进化的共同机制。

Antistatic coating material consisting of poly (butylacrylate-co-styrene) core-nickel shell particle

引用

中国有色金属学会会刊：英文版 2009年第B9期19卷 119-123页

作者： Min-yeong JEONG Byung-Yoon AHN Sang-Koul LEE Won-Ki LEE Nam-Ju jo Department of Polymer Science and Engineering Pusan National University Kumho Petrochemical Samsung Corning Precision Glass Division of Chemical Engineering Pukyong National University

A transparent and antistatic coating material consisting of polymer core-metal shell particle was prepared. As a polymer core, poly(butylacrylate-co-styrene)s ([P(BA-co-sty)s]) with various compositions of butylacrylate and styrene were synthesized by emulsion polymerization. And the effect of comonomer composition on the thermal property of polymer core particle was investigated. By electroless plating method, the nickel particles were formed and deposited on the surface of P(BA-co-Sty) particles to form P(BA-co-Sty) core-nickel shell composite particles. SEM observation confirms that the nickel particles with size of 15 nm are distributed on the surface of the polymer core particles. The surface resistance of P(BA-co-Sty) core-nickel shell composite is 0.8×108Ω/cm2, enough to act as antistatic coating material.

CO2/CH4 separation using inside coated thin film composite hollow fiber membranes prepared by interfacial polymerization

Chinese journal of Chemical Engineering 2017年第3期25卷 278-287页

作者： Eun-Sung jo Xinghai An Pravin G.Ingole Won-Kil Choi yeong-Sung Park Hyung-Keun Lee Korea Institute of Energy Research(KIER) 71-2 Jang-dongYuseong-guDaejeon 205343Republic of Korea Department of Environmental Engineering Daejeon UniversityDaejeonRepublic of Korea Department of Advanced Energy and Technology University of Science and Technology(UST)217 Gajeong-roYuseong-guDaejeon 305-350Republic of Korea

Carbon dioxide(CO_2) is greenhouse gas which originates primarily as a main combustion product of biogas and landfill gas. To separate this gas, an inside coated thin film composite(TFC) hollow fiber membrane was developed by interfacial polymerization between 1,3–cyclohexanebis–methylamine(CHMA) and trimesoyl chloride(TMC). ATR-FTIR, SEM and AFM were used to characterize the active thin layer formed inside the PSf hollow fiber. The separation behavior of the CHMA-TMC/PSf membrane was scrutinized by studying various effects like feed gas pressure and temperature. Furthermore, the influence of CHMA concentration and TMC concentration on membrane morphology and performance were investigated. As a result, it was found that mutually the CHMA concentration and TMC concentration play key roles in determining membrane morphology and performance. Moreover, the CHMA-TMC/PSf composite membrane showed good CO_2/CH_4 separation performance. For CO_2/CH_4 mixture gas(30/70 by volume) test, the membrane(PD1 prepared by CHMA 1.0% and TMC 0.5%) showed a CO_2 permeance of 25 GPU and the best CO_2/CH_4 selectivity of 28 at stage cut of 0.1. The high CO_2/CH_4 separation performance of CHMA-TMC/PSf thin film composite membrane was mostly accredited to the thin film thickness and the properties of binary amino groups.

Effect of serum testosterone and percent tumor volume on extra-prostatic extension and biochemical recurrence after laparoscopic radical prostatectomy

引用

Asian journal of Andrology 2016年第1期18卷 54-59页

Several studies have revealed that the preoperative serum testosterone and percent tumor volume （PTV） predict extra-prostatic extension （EPE） and biochemical recurrence （BCR） after radical prostatectomy. This study investigated the prognostic significance of serum testosterone and PTV in relation to EPE and BCR after laparoscopic radical prostatectomy （LRP）. We reviewed 520 patients who underwent LRP between 2004 and 2012. PTV was determined as the sum of all visually estimated tumor foci in every section. BCR was defined as two consecutive increases in the postoperative prostate-specific antigen （PSA）〉0.2 ng ml^-1. The threshold for serum total testosterone was 3.0 ng ml^-1, Multivariate logistic regression was used to define the effect of variables on the risk of EPE and BCR. A low serum testosterone （〈3.0 ng ml^-1） was associated with a high serum PSA, Gleason score, positive core percentage of the prostate biopsy, PTV, and all pathological variables. On multivariate analysis, similar to previous studies, the serum PSA, biopsy positive core percentage, Gleason score, and pathological variables predicted EPE and BCR. In addition, low serum testosterone （〈3.0 ng ml^-1, adjusted OR, 8.52; 95% CI, 5.04-14.4, P = 0.001） predicted EPE and PTV （adjusted OR, 1.02; 95% CI, 1.01-1.05, P = 0.046） predicted BCR. In addition to previous predictors of EPE and BCR, low serum testosterone and PTV are valuable predictors of EPE and BCR after LRP.

辣椒(Capsicum annuum)是美洲最古老的驯化作物之一,在全世界被广泛种植。本研究对CM334(墨西哥地方品种)进行了全基因组测序和组装(覆盖度为186.6×),同时还对另外两个栽培种和一个野生种分别进行了重测序和从头(de novo)测序。结果表明辣椒基因组大小约为番茄的4倍,辣椒基因组上存在大量gypsy转座子和花椰菜病毒家族元件的积累。结合转录组综合分析认为,辣椒素合成酶基因表达模式的改变及新功能化是导致辣椒素生物合成的原因,研究还发现辣椒与番茄在乙烯合成及果实成熟调控方面存在明显不同的分子模式。辣椒参考基因组的发布为辣椒营养品质和药用价值的改善提供了重要平台。

13Cr martensitic stainless steels(API-5CT)are widely used as the casing pipes in oil and gas industry due to its high strength,hardness,and corrosion resistance,which are directly controlled by the quenching and tempering treatment[1].The quenching process should prevent the formation of carbides with no excessive grain growth for the achievement of maximum strength,while the subsequent tempering reduced
