An investigation and pathological analysis of two fatal cases of cadmium poisoning

Pollution associated with population growth, and with industrial and urban development has led to a serious decline in the water quality of Chinese rivers. Cadmium (Cd) is recognized as one of the most toxic metals and is strongly accumulated by organisms. Humans are exposed to cadmium originating from the environment and from industrial pollution. In spite of thousands of published studies on Cd, there is little information on its pathological features seen in human autopsy. The gross and pathological findings of forensic autopsies of two case of cadmium poisoning are presented and related to an epidemiological investigation. In both cases, multiple organ damage was observed, involving brain, lung, liver, kidney, red blood cells, and platelets, which is consistent with reports in the literature. In particular, in both cases, transmission electron microscopy revealed a large number of dense lysosomal and phagocytic particles in the cytoplasm near the nucleus, indicating the need for a genotoxic study of cadmium. Our observations provide new clues for the future recognition and prevention of Cd poisoning.

诠释信仰:国人宗教心理透视--《中国人的宗教心理--宗教认同的理论分析与实证研究》评介

宗教是人类悠久的文化传统,是现实生活中重要的精神资源,是一种集体的社会意识。但因人类文明发展的多样性,不同的时空区域,宗教的表现形态会有所不同,民众表达其宗教虔敬的模式和信仰心理亦会有很大的差异。年轻学者梁丽萍教授所著《中国人宗教心理———宗教认同的理论分析与实证研究》(中国社会科学文献出版社2003年版),在对已有文献的系统整理基础上,借助于量化与质化多元研究的路径,提供了对中国社会宗教徒宗教心理与行为的一些新的解释框架,为我们解读国人的宗教心理打开了一扇视窗,也填补了我国宗教心理学理论研究的空白。《中国人宗…     

先富群体对社会贫富差距状况的认知:浙江之调查

目前学术界对于中国贫富差距主要从客观的指标尤其以基尼系数来测量与分析,但较少从人们的主观感受、认知来认识,尤其对于作为中国改革开放最为得益的先富群体究竟如何看待社会贫富分化,并没有什么较为实证的调查资料、数据来回答.而社会贫富分化到何种程度是同人们的主观感受有关联的.本文旨在以作者于2004年9月在浙江所做的问卷调查资料来揭示出先富群体对社会贫富状况的认知,即先富者如何看待与分析目前中国社会贫富分化情况.文章的基本结论是,作为中国改革开放得利的先富群体也认为社会贫富分化严重,而造成这种差距过大的原因主要是社会制度性的因素例如分配制度.     

"以德治国"与警察道德建设

"以德治国"是江泽民总书记在新时期提出的一项重要治国方略,其实现的关键环节就在于加强行政伦理建设.警察作为一支重要的行政管理力量,它的道德建设尤为重要.但是,由于种种原因,目前我国的警德建设现状却不容乐观.为此,本人拟对这一问题提出自己的一点思考.     

How the Framework of Implementation Science Guided an Evidence‐Based Dependency Parenting Program Initiative in Florida

In Florida, like most states, many of the parenting programs that are being utilized with families in the dependency system are non‐evidence based, and fail to provide quantifiable data on parent progress during and after completion of the programs. Providing pertinent information in court on parents’ progress in a parenting program, as opposed to simply monitoring attendance, is a growing need voiced by dependency judges and child welfare case management professionals. Clear, reliable information related to parenting skills acquisition and insight can help to ensure that families involved in the child welfare system have access to quality services that improve outcomes for their children. The purpose of this paper is to detail how a statewide initiative to increase the number of Florida circuits providing evidence‐based parenting programs to their clients utilized implementation science to guide their process, and the degree to which the participating circuits achieved full implementation of evidence‐based parenting programs.     

The study and forensic significance of drill bit use indicators

Abstract:  A case study involving an improvised pipe bomb with a drilled fuse hole is presented. This case study and its accompanying research details drill bit use and/or nonuse indicators. These indicators are then further classified to develop relevant conclusion criteria. These criteria are: (1) trace deposits in the form of particulate and/or smears on the drill bit, especially inside the flute and the tip area, (2) physical damage including chipping, abrasion, and fissuring on the drill bit which mostly occurred on the flute edge bevels and lip edges, and (3) thermal damage. One or any combination of these indicators could be used as effective criteria for concluding drill bit usage. This study also determined that a drill bit produces well-defined toolmarks on swarf shavings that could be identified back to that particular tool, and there is no mechanical break-in period for obtaining reproducible toolmarks on newly manufactured or unused bits.     

Methylation-Based Age Prediction Using Pyrosequencing Platform from Seminal Stains in Han Chinese Males

Various methods have been performed to predict an unknown individual's age from biological traces in forensic investigations. A considerably accurate age prediction for the semen donor can help narrow down the search in a sexual assault case. The aim of this study was to develop an assay for age prediction from seminal stains in Han Chinese males. We built a sperm-specific linear regression model using bisulfite pyrosequencing. Validations were conducted with a Mean Absolute Deviation from the chronological age (MAD) of 4.219 years in liquid semen, 4.158 years in fresh seminal stains, 4.393 years in aged seminal stains, and 3.880 years in mixed stains, respectively. Furthermore, our strategy enables accurate age prediction using a forensic casework sample. The strategy indicated that we produced an accurate and reliable age prediction tool for the semen donors in Han Chinese males for forensic purposes.
