Disclosure of child sexual abuse: expressed emotions and credibility judgments of a child mock victim

Both lay persons and professionals believe that the emotions displayed by a child witness during disclosure of sexual abuse are a factor of importance when judging the child's credibility. Unfortunately, not all children display emotions according to expectations, leading to misjudgments, and possible miscarriage of justice. In the present study, we examined how lay people's credibility judgments were influenced by a child's displayed emotions during the disclosure of sexual abuse. Participants (n?=?119), viewed video recordings of a mock police interview of an 11-year-old child actor disclosing sexual abuse, displaying one of four emotional expressions (angry, sad, neutral, and positive). Results showed that participants were strongly influenced by the emotions displayed; in particular, the display of strong negative emotions (anger) or positive emotions during disclosure significantly reduced judged credibility. The credibility ratings predicted the participant? judgments of the defendant's guilt and the willingness to pass a guilty vote in a hypothetical trial.     

加减薯蓣丸对阿尔茨海默病模型大鼠海马区TREM2及Iba1蛋白表达的影响

目的 探讨加减薯蓣丸对阿尔茨海默病(Alzheimers disease,AD)模型大鼠海马区髓细胞触发受体2(triggering receptor expressed on moyeloid cells 2,TREM2)、Iba1蛋白表达水平及对Iba1+细胞数量的影响。方法 采用SD大鼠双侧侧脑室注射β淀粉样蛋白1-42建立AD模型,将模型复制成功的大鼠分为模型组、中药组,并设正常组进行对照,每组10只。正常组、模型组大鼠每日给予10 mL/kg生理盐水灌胃,中药组大鼠每日给予加减薯蓣丸10 g/kg灌胃,连续灌胃4周后,应用Western blot法检测海马区TREM2和Iba1蛋白表达水平,免疫荧光染色标记Iba1+细胞数量。结果 与正常组比较,模型组TREM2蛋白表达水平显著增加（P＜0.05）;与模型组比较,中药组TREM2蛋白表达水平显著降低（P＜0.05）,Iba1蛋白表达水平显著增加（P＜0.05）,中药组海马区Iba1+细胞数量明显增加（P＜0.05）。结论 加减薯蓣丸可能通过影响海马区TREM2及Iba1蛋白水平的表达,增加Iba1+细胞数量,发挥对AD的治疗作用。     

论意思表示的构建

意思表示是民法的核心概念之一。传统理论认为意思表示包括行为意思、表示意思、效果意思和表示行为。对其中表示意思、效果意思与意思表示的关系争论颇多。可以就上述问题从私法自治与信赖保护的角度作以深入的探讨。

微小牛蜱雌蜱唾液腺消减cDNA文库的构建与分析

以我国微小牛蜱半饱血雌性成蜱唾液腺cDNA为检测子Tester),饥饿雌性成蜱cDNA为驱动子(Driver),采用抑制消减杂交技术和T/A克隆技术构建了微小牛蜱半饱血雌性成蜱唾液腺消减cDNA文库。对获得的158个阳性克隆进行PCR鉴定,显示插入片段主要集中在200~550bp之间,挑取60个阳性克隆进行测序,共获得了14个有效ESTs,生物信息学分析推测,它们所编码的功能性蛋白包括卵黄蛋白原、基质蛋白、富含脯氨酸蛋白质、OTM-3假定蛋白等。根据基因序列设计引物,以微小牛蜱DNA为模板,对所得ESTs进行鉴定,证明它们都是微小牛蜱所固有的。该项工作为进一步研究微小牛蜱唾液腺差异表达基因奠定了基础。     

Exploiting expressed sequence tag databases for the development and characterization of gene-derived simple sequence repeat markers in the opium poppy (Papaver somniferum L.) for forensic applications

Simple sequence repeat (SSR) markers in the opium poppy (Papaver somniferum L.) were identified from an expressed sequence tag (EST) database comprised of 20,340 sequences. In total, 2780 SSR-containing sequences were identified. The most frequent microsatellite had an AT/TA motif (37%). Twenty-two opium poppy EST-SSR markers were presently developed and polymorphisms of six markers (psom 2, 4, 12, 13, 17, and 22) were utilized in 135 individuals under narcotic control investigation. An average of three alleles per locus (range: 2-5 alleles) with a mean heterozygosity of 0.167 was detected. Six loci identified 29 unique profiles in 135 individuals. The EST-SSR markers exhibited small degrees of genetic differentiation (fixation index = 0.727, p < 0.001). Other variable markers will be needed to facilitate the forensic identification of the opium poppy for future cases. To determine the potential for cross-species amplification, six markers were tested in five Papaver genera species and two Eschscholzia genera. The psom 4 and psom 17 primer pair was transferable. This is the first study to report SSR markers of the opium poppy.
