唾液中乙醇含量检测试剂条的研究

目的根据唾液和血液中乙醇含量相关性的实验结果,建立了一种简便快速、准确可靠的检测唾液中乙醇含量的方法。方法本方法利用酶学原理,将一定量乙醇氧化酶(ALO)和过氧化物酶以及底物四甲基联苯胺(TMB)固定于试剂条上,当样本中含有乙醇时,酶学反应使底物TMB显色,通过比对反应的不同颜色,对样本中乙醇质量浓度进行半定量。结果用本方法检测300个自愿者的唾液,和用GC/MS法对照检测志愿者唾液中的乙醇含量,定量结果基本一致。本产品检测过程仅需2min,其检测的阈值为0.1mg/mL,敏感度为96.5%,特异性为91%,准确性为94.7%。结论采用酶学方法制备的乙醇含量检测试剂条,通过显色反应对唾液中的乙醇含量进行半定量检测,其特点为快速简便、准确可靠,适合现场使用。     

Polygraphs: Erosion of the privacy right

The polygraph is a machine which invades previously private regions in the human being. Its operation is often viewed simplistically and lacking in danger. Such naivete is the subject of this comment. The paper considers the mechanics of polygraph operation, and its theoretical basis; the legal admissibility of the polygraph in a variety of settings, and lastly the impact the polygraph has upon our private lives.Clearly, the polygraph intrudes on the private regions of each individual, and this frightening fact is cause enough to consider the human, social and constitutional implications of its use. The project considers the reliability factor of the polygraph and its questionable use in personnel and business settings; its use in disciplinary procedures and labor arbitration, as well as reviews its place in judicial process and criminal review.Most critically the paper attempts to arrive at a constitutional basis for restrictions on its use in the private sector. Ingenious arguments have been made by opponents of the polygraph, and this paper reviews the substance and content of these constitutional arguments.

Screening Test for Shed Skin Cells by Measuring the Ratio of Human DNA to Staphylococcus epidermidis DNA

A novel screening method for shed skin cells by detecting Staphylococcus epidermidis (S. epidermidis), which is a resident bacterium on skin, was developed. Staphylococcus epidermidis was detected using real‐time PCR. Staphylococcus epidermidis was detected in all 20 human skin surface samples. Although not present in blood and urine samples, S. epidermidis was detected in 6 of 20 saliva samples, and 5 of 18 semen samples. The ratio of human DNA to S. epidermidisDNA was significantly smaller in human skin surface samples than in saliva and semen samples in which S. epidermidis was detected. Therefore, although skin cells could not be identified by detecting only S. epidermidis, they could be distinguished by measuring the S. epidermidis to human DNA ratio. This method could be applied to casework touch samples, which suggests that it is useful for screening whether skin cells and human DNA are present on potential evidentiary touch samples.     

Co‐Parent Court: A Problem‐Solving,Community‐Based Model for Serving Low‐Income Unmarried Co‐Parents

The Hennepin County Co‐Parent Court Project was a 3‐year demonstration project for unmarried co‐parents. The goal of the project was to remove barriers to co‐parenting in low‐income, unmarried parents. The Co‐Parent Court Project encompassed a number of services, including educational workshops, individual case management, parenting plans, legal mediation, and, if needed, supports and treatment for domestic violence. There are published articles that highlight the participant outcomes of the Co‐Parent Project. This article, however, focuses on the background for why this project was developed, components of this project, and lessons learned from implementation.     

德州市水域中硅藻分布的研究

目的研究德州市水域中硅藻分布的特点,建立德州市春季和夏季的各水域硅藻数据库。方法对德州市主要水域的130个取水地点进行春季和夏季两次采样,用强酸消解-真空抽滤-扫描电镜法检测各水域中硅藻的种属及含量,统计分析水域中硅藻含量、群落组成、相对丰度和优势种属特点。结果夏季的硅藻含量高于春季的硅藻含量,河流两个季节硅藻含量无统计学显著差异(P>0.05),湖泊和水库两个季节硅藻含量存在统计学差异(P<0.05)。各水域之间硅藻含量存在差异,含量最高为608020个/10mL,最少为10个/10mL。各水域之间种属组成、优势种属和种属优势率存在差异。结论德州地区不同水域、不同季节的水中硅藻种属和含量具有明显的特异性;建立硅藻数据库和掌握本地区水域中硅藻种属特点,有助于德州市水域内水中尸体案件硅藻的检验和落水地点的判断。
