Keine Unterbrechung der Rechtsmittelfrist durch weiteren (überflüssigen) Antrag auf Verfahrenshilfe / Rechtsprechungsänderung

Wurde schon ein Rechtsanwalt rechtskr?ftig zum Verfahrenshelfer bestellt, so bewirken ein weiterer diesbezüglicher Antrag und eine neuerliche Bestellung eines Verfahrenshelfers keine zus?tzliche Unterbrechung der Rechtsmittelfrist. Der neuerliche Antrag w?re richtigerweise als unzul?ssig zurückzuweisen.

应用CT三维重组技术判定胸骨性别的研究

目的建立利用三维重组形态学指标判定胸骨性别来源的方法,并对其判定效果进行评价,考察虚拟骨骼的法医学应用价值。方法应用胸部螺旋CT扫描图像,通过多层面重组法获取胸骨的二维影像,结合容积再现技术得出的三维模型,分别测量胸骨的全长、柄长、体长、柄最大宽、体最大宽、柄最大厚、体最大厚、体上端厚等8项指标,并计算出3个比值指标;筛选出其中有性别差异的指标,建立性别判别方程并评价其判别效果。结果 11个指标的性别差异均具有统计学意义(P0.05),但以胸骨全长、胸骨体长、体最大厚及柄最大宽的判别效果较好。所建方程组中,全指标、长度指标判别方程及逐步判别方程的判别率较高,88.6%的判定率与近期国外有关性别判定研究的报道结果基本一致。结论应用多层螺旋CT三维重组技术判定国人胸骨性别具有较高的可行性和准确性,该技术有望应用于胸骨年龄推断及其它虚拟骨骼的研究。     

引物3'端第二个碱基SNP变异的长度多态性遗传标记检测

目的为了获得引物3'端存在SNP点突变的插入缺失遗传标记rs10644346所有等位基因片段。方法基于等位基因特异性PCR原理,设计一条共用上游引物,二条3’端倒数第二个位置特异性碱基的下游引物。运用该三条引物检测150个无关个体及10例亲子关系已确定的三联体,同时运用其中二条引物(共同上游引物和其中一条下游引物)扩增9例样本。结果三条引物扩增150个无关个体均有清晰扩增片段;10例三联体案例亲代与子代扩增片段均符合孟德尔遗传定律;二条引物扩增9例样本后发现特定片段丢失。结论本次研究设计的三条引物PCR,证明特异性碱基位置除了通常的3'末端,理想条件下3'端的其他位置(如倒数第二个位置)也可以成为有效选择,该三条引物设计方法为检测引物侧翼存在点突变的遗传标记提供了一种新的参考。     

云南汉族NR3C1基因多态性与暴力攻击行为相关性

目的为了探讨云南汉族人群糖皮质激素受体基因(NR3C1)多态性与攻击行为的相关性。方法应用改良多重高温连接酶反应(improve multiplex ligasedetection reaction,iMLDR)技术检测194例云南汉族有攻击行为的监狱服刑人员和301例健康对照样本的NR3C1基因SNPs(rs6190、rs6191、rs6198、rs41423247、rs56149945)基因型,采用SPSS19.0软件、PHASE2.1平台进行统计学分析。结果 rs6191和rs41423247单个基因座的等位基因分布在非攻击组与攻击组、抢劫亚组和故意伤害亚组中均无显著性差异;rs41423247的基因型在非攻击组与抢劫亚组中的分布有显著性差异(p=0.048);构建的4种单倍型分布在非攻击组与攻击组、抢劫亚组和故意伤害亚组中均无显著性差异。结论云南汉族人群NR3C1基因的rs41423247基因座的单基因座多态性可能与指向他人的躯体攻击行为相关,rs6191基因座的单基因座多态性可能与暴力攻击行为无关。     

TAR DNA结合蛋白43的表达与脑损伤的相关性研究进展

TAR DNA结合蛋白43(TAR DNA-binding domain protein 43,TDP-43)是一种高度保守、广泛表达的核蛋白。如今发现TDP-43在大多数神经退行性疾病如阿尔茨海默症患者中表达,为神经退行性疾病相关的标记蛋白。本文从目前国内外的研究现状出发,围绕TDP-43的表达与脑损伤的相关性,在对TDP-43生物学特性认识的基础上,着重探讨TDP-43在急、慢性颅脑损伤中的特殊表达与作用,从而探索TDP-43在法医病理学中确定死亡原因、判定致伤致残情况的可行性。     

Testing a Novel 3D Printed Radiographic Imaging Device for Use in Forensic Odontology

There are specific challenges related to forensic dental radiology and difficulties in aligning X‐ray equipment to teeth of interest. Researchers used 3D printing to create a new device, the combined holding and aiming device (CHAD), to address the positioning limitations of current dental X‐ray devices. Participants (N = 24) used the CHAD, soft dental wax, and a modified external aiming device (MEAD) to determine device preference, radiographer's efficiency, and technique errors. Each participant exposed six X‐rays per device for a total of 432 X‐rays scored. A significant difference was found at the 0.05 level between the three devices (p = 0.0015), with the MEAD having the least amount of total errors and soft dental wax taking the least amount of time. Total errors were highest when participants used soft dental wax—both the MEAD and the CHAD performed best overall. Further research in forensic dental radiology and use of holding devices is needed.     

Case of Fatal Starvation: Can Stable Isotope Analysis Serve to Support Morphological Diagnosis and Approximate the Length of Starvation?

The diagnosis of death as a result of starvation is established on anthropological measurements, visual appearance of the deceased on external and internal examination, microscopic analysis, laboratory testing, and exclusion of other causes of death. Herein, we present our findings on a case of 95‐year‐old man who died of starvation. After the diagnosis of starvation was established by traditional forensic medicine methods, we have conducted retrospective segmental analysis of stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope ratios in hair sample. This method reveals periods of starvation through decrease in δ¹³C and increase in δ¹⁵N along the strand of hair. Our analysis revealed the decrease of 0.6 ‰ in δ¹³C during the last 10–12 weeks prior to death, similar as reported in other investigations. Also, a decrease of 0.7 ‰ in δ¹⁵N during the last 8–10 weeks prior to death was determined that was different than observed in previous studies.
