Screening for cannabinoids in blood using EMIT: concentrations of delta-9-tetrahydrocannabinol in relation to EMIT results.

The EMIT d.a.u. cannabinoid assay of methanolic extracts of blood was found to be usable as a screening method in cases of suspected impairment by cannabis, when delta-9-tetrahydrocannabinol (THC) was analysed in the subsequent assay. A prerequisite is that the blood sample is taken some time after cannabis smoking. When a cut-off limit corresponding to 50 nM delta-9-tetrahydrocannabinol carboxylic acid (17 ng/ml) was used, 86% of the EMIT positive blood samples contained THC concentrations above the cut-off limit of 1 nM (0.3 ng/ml). A high EMIT result gave a high probability of finding a high THC concentration in the subsequent confirmation analysis.     

Sexing of human clavicles using length and circumference measurements

Measurement of clavicular length and circumference, and computation of clavicular robustness and length-circumference product from 724 autopsied adults of known age, sex, and body length between the ages of 15 and 96 years produced useful sex-predictive values. This predominantly North American white population contained 560 males and 164 females with intact, nondeformed clavicles. Clavicle length and circumference and particularly their product have been found useful in sexing, but robustness as a single trait has not. Despite a significant overlap of male and female values, the use of single cutoff values allowed correct sex assignment of up to 93% of the entire study population, including 94% of males and 89% of females. The ratios of body length to clavicle circumference and to clavicle length are on average greater in women than in men. The former ratio yields male predictive values greater than 95% for those individuals with ratios falling below the cutoff value of 43, whereas the latter ratio is a relatively poor sex predictor.     

The Injustice of Enforced Equal Access to Transplant Operations: Rethinking Reckless Claims of Fairness

The globalizing or totalizing imposition of a particular understanding of justice, fairness, or equality, as seen, for example, in Canada's single health care system, which forbids the sale of private insurance and the purchase of better basic health care, cannot be justified in general secular terms because of the following limitations: (1) the plurality of understandings of justice, fairness, and equality, and (2) the inability to establish one understanding as canonical. The secular state lacks plausible moral authority for the coercive imposition of one such account on peaceable, consenting adults. This state of affairs, with regard to the weakness of human moral epistemological powers, means that the secular state fails to have the moral authority to forbid coercively the sale and purchase of organs. It further lacks the secular, moral authority to impose equal access to organ transplantations. Assertions of such authority amount to reckless claims of fairness, and for this reason, health care policy must be set within the constraints of limited, constitutional regimes.     

试论康有为关于孔教运动的理论建设问题

本文论述了康有为孔教运动的理论建设问题。在致思理路上,康有为的孔教运动有着由儒学而来的宗教内容,由佛学而来的宗教精神以及由基督教而来的宗教形式。在具体的理论建设上,康有为的孔教运动分为确定孔教运动理论建设的基本框架,阐述孔教运动的远景目标、必经阶段理论以及阐明孔教运动中＂出世间事＂理论这样三个阶段。康有为孔教运动的理论建设开辟了儒学研究中宗教儒学的新向度。     

青海血蜱成蜱cDNA表达文库的免疫学筛选及阳性克隆分析

采用兔抗青海血蜱幼蜱阳性血清,对青海血蜱成蜱cDNA表达文库进行免疫学筛选,并对获得的阳性克隆进行序列测定及同源性分析.结果显示,共获得9个新cDNA序列,其中3个新基因序列已被GenBank接受,并获得序列接受号.表明,从青海血蜱成蜱cDNA表达文库筛选到一批新基因,为青海血蜱保护性抗原的筛选奠定了基础.     

PKC在青壮年猝死综合征心肌组织中的变化

目的探讨蛋白激酶C（PKC）与青壮年猝死综合征之间的关系。方法取30例青壮年猝死综合征、20例正常对照心脏标本的左右心室肌、窦房结、房室结组织,通过免疫组化学染色,应用图像分析软件对PKC分布及强度变化进行定量检测分析,并进行统计学处理。结果青壮年猝死者心肌细胞PKC平均灰度值及面积代数和显著高于正常对照组（P〈0.05）;其中青壮年猝死者窦房结中的PKC平均灰度值大于房室结（P〈0.05）。结论PKC作为体液调节的途径之一,参与青壮年猝死发病过程,并起到保护性作用。PKC可以作为诊断青壮年猝死的一项参考指标。     

让"无处不在的眼睛"更敏锐——当前新闻舆论监督的问题与对策

新闻舆论监督在当今社会生活中发挥着日益强大的影响力,是现代社会监督体系的一个重要方面,其作用越来越受到党和政府及社会各界的重视。但是,由于我国正处在经济转型期,新闻舆论监督进程中还存在一些不容忽视的问题,新闻要真正发挥舆论监督作用还存在着一定的难度。要让＂无处不在的眼睛＂在构建和谐社会的今天更敏锐,必须科学认识舆论监督的意义,加快新闻立法进程,健全新闻舆论监督的法律体系,同时建立多层次、多渠道的舆论监督网络,强化新闻工作者的素质提升和形象塑造等,进而探寻我国新闻舆论监督的完善路径。
