Influence of N, P additions on the transfer of nickel along the food-chain

【中文摘要】 采用放射性同位素示踪法,研究氮或磷添加对镍在东海原甲藻(Prorocentrum donghaienseLu)和中肋骨条藻(Skeletonema costatum)胞内累积的影响;并将其分别投喂中华哲水蚤(Calanus sinicus)后,探讨镍在桡足类体内的吸收和生理周转。结果表明,经过24h暴露后,氮或磷显著影响这两种藻类对镍的吸收,且高浓度氮或磷均能促进镍在这两种藻类细胞内的累积,因而促进镍在中华哲水蚤体内的吸收;而镍在中华哲水蚤体内的生理周转率却不受氮或磷浓度的影响,似乎更受动物个体的生理状态影响;中华哲水蚤对镍的吸收率与藻类细胞内镍含量呈极显著相关(p<0.001),证明了"桡足类只吸收饵料细胞内的水相金属库"的假说。由此可见,近海富营养化可促进浮游植物对镍的吸收,进而影响该金属在浮游生物食物链上的传递。 【英文摘要】 We examined the influence of macronutrient (nitrate or phosphate) additions on the bioaccumulation of Ni in two species of phytoplankton (Prorocentrum donghaiense Lu and Skeletonema costatum), and its subsequent assimilation and physiological turnover in marine copepod (Calanus sinicus) after ingestion, using a radioactive-tracer method.

采用rAPd和MTdnA16SrrnA基因序列分析方法对海南和马来西亚斑节对虾(PEnAEuS MOnOdOn)种群进行了遗传多样性和遗传分化研究。结果表明:15个rAPd随机引物共检测到82个位点,海南和马来西亚种群的多态位点比例分别为75.90%和76.83%,杂合度分别为0.199和0.218,遗传多样性指数分别为0.276和0.288,种群间的遗传距离为0.015;16SrrnA基因检测的种内遗传变异较低,马来西亚和海南种群的核苷酸多样性分别为0.011和0,种群之间的遗传距离为0.008;马来西亚种群比海南种群的遗传变异水平要高得多,且海南种群可能起源于马来西亚种群;进行遗传选育时可考虑引进马来西亚亲虾作为奠基群体。By using RAPD and mtDNA 16S rRNA gene sequence analysis,this paper studied the genetic diversity and differentiation of two Penaeus monodon wild broodstock populations collected from Hainan and Malaysia.Using 15 random primers,a total of 82 RAPD loci were detected.For the Hainan and Malaysia populations,the proportion of polymorphic loci was 75.90% and 76.83%,heterozygosity was 0.199 and 0.218,and genetic diversity index was 0.276 and 0.288,respectively,and the genetic distance between the two populations was 0.015.The genetic variation revealed by 16S rRNA gene sequence analysis was low.The nucleotide diversity of the Hainan and Malaysia populations was 0.011 and 0,respectively,and the genetic distance between the two populations was 0.008.Phylogeographic pattern analysis indicated that Malaysia population had a higher genetic diversity than Hainan population,and the Hainan population could be derived from Malaysia population.Therefore,the broodstock imported from Malaysia could be used as the founder in genetic breeding programs.国家自然科学基金项目(30471322);湖南省教育厅资助科研项目(08B024)资

斑节对虾的遗传育种研究

斑节对虾(Penaeus monodon)俗称草虾,是世界三大养殖虾类之一。广泛分布于印度洋和西太平洋,也是我国本土优质对虾资源之一,但尚未形成遗传稳定的养殖品系,养殖种苗除少数来自海捕外,绝大多数通过人工繁殖获得。供人工繁殖的亲虾主要来自两方面:一是捕捞野生怀卵虾,二是通过摘除眼柄和人工诱导野生雌虾性成熟和产卵,但二者均依赖野生资源。斑节对虾养殖的迅速发展对野生资源造成了极大的压力,过度开发势必引起种质的退化;同时,长期依赖野生亲体培育苗种产生了一些弊端,如亲体携带病毒,养殖对象生长减慢,抗病力下降等。因此,为保护野生资源和阻止野生虾类遗传多样性的丧失,尽快形成遗传稳定的养殖品系显得尤为迫切

人脐血间质干细胞一般特性及其多向分化潜能

【目的】观察人脐血间质干细胞增殖能力、细胞表面分子标志及多向分化潜能。【方法】从人脐血中分离出单个核贴壁细胞并进行体外培养。将细胞以单克隆抗体标记后用流式细胞仪进行检测。向培养细胞中加入成骨、成软骨和成脂肪诱导剂，检测其多向分化能力。【结果】脐血间质干细胞原代培养时间为7周。流式细胞分析显示这些细胞CD29、CD13、CD44等表达为阳性，但是它们不表达造血干细胞表面标志物。加入成骨诱导剂会导致细胞碱性磷酸酶的表达。采用微球培养法并加入软骨诱导剂对细胞进行诱导，用阿尔新蓝染色显示有蛋白多糖表达。在加入成脂诱导剂后，会导致细胞形态学改变，且油红O染色为阳性。【结论】通过体外传代培养的方法可以从人脐血单个核贴壁细胞中得到纯化的间质干细胞。脐血有望成为间质干细胞的替代来源

Formation and solving for the micro-waves of fly-cut surface introduced by spindle error

为分析超精密飞切机床加工表面微波纹的形成机理,研究了主轴回转误差信息提取与表面形貌仿真技术,获取微波纹误差来源并研究解决方案。首先,在超精密飞切机床主轴上搭载五通道在线电容位移检测系统,并对采集到的信号进行误差分析提取。然后,建立飞切加工表面微观形貌三维仿真模型,仿真分析主轴误差引入的加工表面微波纹,并与表面检测结果比对确定误差来源。最后,通过调整主轴电机控制系统抑制该误差。三维仿真和实测结果相吻合,证实超精密飞切机床主轴转速波动导致的回转误差造成了工件表面1 Hz左右的规律性条纹,对主轴转速控制系统进行数字化改造后,基本消除了该因素导致的表面微波纹,表面粗糙度从5 nm以上抑制到2 nm左右,PV值优于10 nm。超精密飞切机床主轴转速波动会对飞切加工表面微观形貌以及表面粗糙度产生显著影响,需至少控制在0.5 r/min以内。In order to find out the formation mechanism of micro-waves on the fly-cut surface,the spindle motion error was sampled and a 3D topography simulation model was compiled. Firstly,a nano-class testing and evaluation system was established on the fly cutting machine,the displacement data was sampled and the spindle motion error was analyzed.Then a 3D surface profile topography simulation model was established to analyze the micro-waves caused by the spindle motion error. The simulated surface was compared with the measured surface to find out the error sources. Finally,the characteristics of spindle were improved by adjusting the control system of the spindle motor. The simulated 3D surface profile topography was similar to that of the measured profile,which verified that the macro-waves was caused by the undulate of the spindle speed. When the spindle characteristics was improved,the macro-waves caused by the spindle motion error almost disappeared,and the surface roughness reduced from more than 5 nm to 2 nm. It is thus concluded that the undulate of ultra-precision fly cutting machine spindle speed causes macro-waves on the work-piece surface,and the undulate spindle speed must less than 0. 5 r / min.基金项目:高档数控机床与基础制造装备《强激光光学元件超精密制造关键装备研制》(2013ZX04006011-102-001
