新疆额尔齐斯河水系银鲫克隆多样性研究 [PDF]

open access: yes, 2009
银鲫(Carassius auratus gibelio Bloch)由于其独特的遗传背景和繁殖方式而成为研究进化遗传学和选择育种的一个独特的模式生物。到目前为止,我们对新疆额尔齐斯河水系银鲫群体的多样性状况一直知之甚少。为了更好地了解额尔齐斯河水系银鲫群体的克隆多样性状况,本研究中,我们采集了来自新疆额尔齐斯河水系的4个鲫鱼群体。通过流式细胞术分析血细胞样品,结果证实这些鲫鱼均为三倍体银鲫。通过血清转铁蛋白电泳表型分析,我们从这些银鲫群体中鉴定出总共8个不同的克隆。在这些鉴定的克隆中,有4个克隆 ...

Acid‐Etched Co‐Vacancy‐Tunable CoFeP/N,P‐Codoped Carbon Nanocages for Highly Efficient Alkaline Water Electrolysis

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

DNA微阵列芯片法与常规生化法在分枝杆菌菌种鉴定方面的比较

open access: yesZhongguo shiyan zhenduanxue, 2013
目的通过DNA微阵列芯片法进行分枝杆菌菌种鉴定与常规生化法进行比较,分析其特点,提高分枝杆菌菌种鉴定水平,更好的为临床服务。方法选择我院2010年1月至2013年3月从临床标本中分离培养后所得的结核分枝杆菌复合群12株(其中含1株牛型结核分枝杆菌),非结核分枝杆菌31株,分别用DNA微阵列芯片法和常规生化法进行鉴定。结果 DNA微阵列芯片法进行分枝杆菌菌型鉴定与普通生化培养法鉴定结果符合率为100%,对常规生化法未定型的两株非结核分枝杆菌也分别定型为1株土分枝杆菌,1株耻垢分枝杆菌。结论 ...

Empirical research on procedures for compulsory medical treatment of mental patient [PDF]

open access: yes, 2015
2012年,新修订的《刑事诉讼法》新增设了“依法不负刑事责任的精神病人的强制医疗”这一特别程序,使我国的精神病人强制医疗程序明确进入司法审查的范围,填补了该领域的立法空白,对于保护公共安全、保障精神病人人权,解决我国强制医疗领域长期存在的“该收治的不收治、不该收治的被收治”问题起到了根本性的作用。2015年8月7日,湖南省高级人民法院召开新闻发布会,称新刑诉法实施以来,湖南省法院共受理强制医疗案件157件,受理申请解除强制医疗决定案件18件,取得积极的效果。但从刑事强制医疗程序运行两年多的情况看 ...

基于粪便DNA技术的鸟类物种鉴定体系研究

open access: yes野生动物学报, 2020
利用粪便DNA技术对候鸟进行物种鉴定,对了解鸟类在繁殖地和越冬地的种类分布、研究其迁徙路线等具有重要意义。本研究扩增、测定了76份雁形目鸟类粪便的D-loop区序列,将其与NCBI数据库中已知鸟类同源序列进行比对分析(BLAST比对法)。结果表明:相似度为98.07% —100%,其中75%的单倍型可以被认定为单一物种,25%的单倍型检测为非单一物种,即包含2个近缘物种。比较基于Ts、Ts +Tv碱基替换计算的K2P遗传距离,说明后者更适合于D-loop区序列特征。而且,以此为基础的遗传距离法 ...

Design and Implementation of Urban Housing Security Identification Management System [PDF]

open access: yes, 2016
随着我国经济不断发展和商品房制度改革,我国城镇化水平不断提高,房地产市场得到快速发展,每年各类新增房屋规模和数量非常巨大。在这一背景下,不论是新增房屋还是存量房屋的城市房屋安全质量问题正成为城市居民和房地产行政管理主管部门日益关注的重要问题之一。 房屋安全鉴定工作是房地产行政主管部门管理工作的重要组成部分,使用传统人工作业的方式往往难以满足日常房屋安全鉴定各项工作。进入21世纪,随着计算机科学技术、信息化技术和互联网技术浪潮席卷而来,随着信息化、网络化技术日益进步和拓展 ...

A Tale of Two Programs? Stigma and Administrative Burdens in CHIP and Medicaid

open access: yesWorld Medical &Health Policy, Volume 18, Issue 1, March 2026.
ABSTRACT One contributing factor to undersubscriptions is administrative burdens. To explore whether program stigma affects attitudes about administrative burdens, a survey (N = 2204) was fielded to assess differences in attitudes about seven policies decreasing administrative burdens and two policies increasing administrative burdens.
