The Application of Voltammetric Analysis of Δ9‐THC for the Reduction of False Positive Results in the Analysis of Suspected Marijuana Plant Matter

The development of methodologies using inexpensive, fast, and reliable instrumention is desirable in illicit drug analysis. The purpose of this study was based on cyclic voltammetry technique to differentiate the electrochemical behavior of ?⁹‐THC, the psychoactive substance in marijuana, and five different extract plants to yield false positive results after analysis protocol for cannabinoids using thin‐layer chromatography and Fast Blue B salt. After applying a deposition potential of ?0.5 V in a glassy carbon working electrode, the results indicated an anodic peak current at 0.0 V versus Ag/AgCl after addition of ?⁹‐THC solution in the electrochemical cell, and limits of detection and quantification were 1.0 ng mL^?1 and 3.5 ng mL^?1, respectively. Other interfering plants showed distinct amperometric responses. This methodology was useful to detect ?⁹‐THC even in the presence of the Fast Blue B salt, which avoided false positive results for all the studied extract plants.     

Evaluation of Postmortem Cerebrospinal Fluid S100B Protein and Serotonin Levels: Comparison of Suicidal Versus Nonsuicidal Deaths in Konya,Turkey

Although suicide is a preventable public health problem, objective assays for suicide risk are limited. In this study, it was aimed to determine levels of S100B protein and serotonin as a marker for risk of suicide. S100B protein and serotonin levels were investigated with ELISA method in the cerebrospinal fluid (CSF) in medicolegal autopsy cases, including those of suicide cases (n = 32) and nonsuicide cases (n = 56). The CSF S100B levels were higher (9.3 ± 2.9 ng/mL vs. 5.4 ± 2.0 ng/mL), and serotonin levels were lower (10.4 ± 4.9 ng/mL vs. 19.0 ± 5.7 ng/mL) in suicide group than nonsuicide group (p < 0.05). There was no correlation between S100B protein and serotonin levels with gender, age groups, postmortem interval, and cause of death. It is concluded that both S100B protein and serotonin in CSF may be useful for determination of suicide risk.     

A case of mistaken identity: The wrongful classification of Islamic marriage contracts as premarital agreements in New York

New York precedent has mischaracterized Islamic marriage contracts, or nikah agreements, as premarital agreements. Nikah agreements are not premarital agreements; they are contracts. This mischaracterization has subjected nikah agreements to the acknowledgement requirement codified in N.Y. DRL § 236(B)(3) which has incorrectly been used to strike down valid contracts which Islamic litigants rely on. To prevent the effects of this mischaracterization, this Note suggests to New York appellate courts that a recharacterization of these agreements as contracts would prevent further confusion amongst the lower courts and allow for clearer, more uniform decisions.

GABA Receptors,Alcohol Dependence and Criminal Behavior

The aim of this study was to analyze the connection between alcohol dependence and criminal behavior by an integrated genetic–environmental approach. The research, structured as a case–control study, examined 186 alcohol‐dependent males; group 1 (N = 47 convicted subjects) was compared with group 2 (N = 139 no previous criminal records). Genetic results were innovative, highlighting differences in genotype distribution (p = 0.0067) in group 1 for single‐nucleotide polymorphism rs 3780428, located in the intronic region of subunit 2 of the GABA B receptor gene (GABBR2). Some environmental factors (e.g., grade repetition) were associated with criminal behavior; others (e.g., attendance at Alcoholics Anonymous) were inversely related to convictions. The concomitant presence of the genetic and environmental factors found to be associated with the condition of alcohol‐dependent inmate showed a 4‐fold increase in the risk of antisocial behavior. The results need to be replicated on a larger population to develop new preventive and therapeutic proposals.     

青壮年猝死综合征SCN2B、SCN4B基因检测

目的寻找SCN2B、SCN4B基因的变异位点,探讨其与青壮年不明原因夜间睡眠中猝死(SMDS)的关系。方法提取SMDS病例组及健康对照组的基因组DNA,采用聚合酶链式反应(PCR)方法扩增SCN2B、SCN4B基因编码区外显子、外显子-内含子交界区以及3'侧翼区序列,直接行DNA测序以明确遗传变异类型。结果在病例组中共检测到4个变异位点,c.237+27AG,c.*38CT,c.174CT(p.C58C)和c.*7CT。结论本研究首次对中国人SMDS病例进行了SCN2B、SCN4B基因的检测,上述基因是否为中国人SMDS的易感基因尚有待进一步研究证实。     

Der Haftrücklass im Bauträgervertrag

Das BMJ hat vor Kurzem den Begutachtungsentwurf für eine Novelle zum Bautr?gervertragsgesetz vorgelegt. Ein zentrales Regelungsanliegen des Entwurfs ist die Einführung eines zwingenden Haftrücklasses zur Sicherung allf?lliger Gew?hrleistungs- und Schadenersatzansprüche des Erwerbers auf Grund mangelhafter Leistung des Bautr?gers. Der vorliegende Beitrag setzt sich mit diesem Vorschlag kritisch auseinander.     

我国海事请求保全与美国Rule B Attachment制度之比较

我国海事请求保全制度与美国Rule B Attachment制度,作为海商法领域所特有的强制性财产保全措施,皆是本国海事诉讼中的一项重要而特有的制度,它是保证海事请求权人所受损害得到赔偿的最有效的法律手段之一。鉴于中美两国在国际航运界的显著地位,这两项制度的特殊性及重要性不言而喻,本文从比较法的层面探讨这两者之间的异同,以便更好的理解和把握。     

鸡盲肠扁桃体中B淋巴细胞的发育

通过免疫组织化学方法,应用IgM、IgG和IgA单克隆抗体研究了IgM~+、IgG~+和IgA~+B淋巴细胞在鸡盲肠扁桃体中的出现、迁移、组织定位分布以及数量变化规律等一系列发育过程.结果显示,IgM~+细胞在胚胎20日龄时开始出现,而IgG~+和IgA~+细胞均在雏鸡出壳后1日龄时出现.在定位分布变化上,4日龄之前,B淋巴细胞主要分布在黏膜上皮下固有层中;4～7日龄时,B淋巴细胞则主要分布在黏膜固有层的中上部区域,随后各日龄B淋巴细胞均匀地分布在黏膜固有层中;14日龄时,黏膜固有层中出现主要由B淋巴细胞组成的生发中心,21日龄时可见轮廓更清晰的生发中心存在于黏膜固有层中下部区域,并且生发中心中存在大量的IgM~+、IgG~+和IgA~+细胞.在数量变化上,B淋巴细胞随着日龄增长数量持续增加,直至35日龄时趋于稳定,各日龄的B淋巴细胞数量始终以IgM~+细胞最多,IgA~+细胞次之,IgG~+细胞最少.证实,鸡出壳后初期盲肠扁桃体的体液免疫功能逐渐增强,并在35日龄时达到成熟水平.
