Interrogation of short tandem repeats using fluorescent probes and melting curve analysis: A step towards rapid DNA identity screening

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR^® SGM Plus^® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h.     

对重点人口管理制度的经济分析

重点人口管理在实践中存在着许多普遍性问题,原因在于制度设计时未考虑经济因素.对重点人口管理制度进行经济分析,可以发现其管理制度存在运行成本过高导致执行主体缺乏投入的积极性和可能性、监督成本过高导致监督缺位和"产权"设定的不合理挫伤了成本投入主体的积极性等缺陷.重点人口管理应从列管、核实查证、日常管理三个环节来降低运行成本;通过改革监督评价指标来降低监督成本;通过交易明晰"产权",使成本投入者在重点人口管理工作中获得应有的收益.     

刑事附带民事诉讼死亡、残疾赔偿金审判探析

死亡赔偿金、残疾赔偿金的刑事附带民事赔偿问题，囿于立法、司法解释不明确和矛盾、司法实践中当事人赔偿能力低下、大多无财产可供执行的困难等诸因素，在是否列入刑事附带民事的赔偿范围及如何判赔问题上存在颇多争议。笔者在综合考察研究相关的立法、司法解释及刑事附带民事赔偿审判实践的基础上，主张应当列入赔偿范围且应当全额判赔。但应当给原告出具风险告知书并尽可能争取调解解决。进入强制执行阶段後，如有财产的，全额执行；如无履行能力的，则应中止或终结执行。同时，对因中止或终结执行而生活极端贫困被害人及其抚养人应给予国家补偿救济或“低保”。     

论濒危民俗文化知识产权行政保护管理机制——基于制度分析视角

目前,我国许多民间文化艺术形式正面临着割裂消失、甚至被异化的危险境地;中国传统的口头、形体和其他种类的艺术形式,譬如刺绣、印染、剪纸、雕刻、中医药、针灸等民俗文化遗产的生存发展和保护都面临困境。我国正式加入《保护非物质文化遗产公约》后,应当加强保护民俗文化遗产的行政管理机制,提高对民俗文化遗产保护和知识产权行政管理保护水平。

网络格式合同若干法律问题的探讨

消费者进行网上访问、参与电子商务交易活动大多通过订立网络格式合同进行,而网络格式合同作为人们从事电子商务活动的最主要的手段,在迅速发展起来的同时被赋予了新的内容和形式,不可避免地对传统的合同法律制度提出了挑战。基于此在探析网络格式合同的新内涵并分析和审视网络格式合同法律效力的基础上,提出借鉴外国相关立法和实践经验,针对电子商务交易进行单独立法和课以网络格式合同提供方以合理提示义务,加强行业协会监管作用等措施来规范网络格式合同使用过程中产生的法律关系。     

Survival analysis: A survey

This paper is a survey of statistical methods used to analyze the length of time until a specified event occurs. These models have often been used to analyze the survival times (i.e., time until death) of medical patients, and so the term survival analysis is natural. In criminology, the main application of these models has been to analyze the time until recidivism, but many other applications are possible. The paper summarizes the statistical literature on survival analysis, and describes its applications in criminology. The methods are illustrated by an application to the prediction of time until recidivism for a sample of North Carolina prison releasees.     

Toxicological analysis after asphyxial suicide with helium and a plastic bag

A 23-year-old man was found on a raised hide in lying position, the head wrapped in a plastic bag connected with a helium gas cylinder by a polypropylene tube. The autopsy did not show any specific findings nor did the routine toxicological analysis reveal significant information regarding the cause of death (BAC 0.9 mg/g, diphenhydramine 0.81 μg/ml in heart serum). For the detection of helium in the lungs, gas samples from both lungs were collected by a method ensuring minimal dilution. Gas analyses were performed using a GC–MS with a split–splitless injector and a headspace syringe. As carrier gas the commonly used helium was replaced by nitrogen. Helium was found in clearly elevated concentrations in gas samples from both lungs. Therefore, suffocation by breathing helium enriched, and thus oxygen deficient atmosphere, can strongly be assumed as the cause of death.     

Detection of Gamma-Hydroxybutyric Acid in Various Drink Matrices via AccuTOF-DART*

Abstract: A new screening method for detecting gamma-hydroxybutyric acid (GHB) in drink matrices, using the IonSense, Inc. (Saugus, MA) direct analysis in real time (DART) ion source coupled to a JEOL exact mass time-of-flight mass spectrometer (AccuTOF), was validated and compared with the current screening methodology. The DART ion source allows for analysis of samples under ambient conditions with little to no sample preparation. Fifty drink specimens were spiked at levels of 1, 2, 3, and 4 mg/mL GHB, and analyzed on the AccuTOF-DART. Positive detection of GHB occurred for each of the samples at each concentration level, giving 100% accuracy for the samples tested. Twenty-five of the 50 drink specimens were spiked at 1 mg/mL GHB and tested using a color test known as the GHB Color Test #3. Only two of these 25 specimens tested positive for the presence of GHB, giving only 8% accuracy. Implementation of this new methodology as a screening tool for GHB analysis will quickly eliminate negative specimens allowing the examiner to focus analysis time on those that screened positive.
