测量中国汉族女性腰椎,建立腰椎推断身高的方法。按人体骨骼测量方法,对第一至第五腰椎的10项指标进行测量,并将各腰椎的测量数据与身高进行相关分析,建立中国汉族女性腰椎推断身高的回归方程。获得的推断身高的5个回归方程,其相关系数(r)和标准差(s)分别为 r_1=0.751,s=45.0171;r_2=0.698,s=48.2804;r_3=0.758,s=43.3508;r_4=0.497,s=56.0890;r_5=0.606,s=53.3158。本研究建立的方法误差小,可以用于中国汉族女性腰椎的身高推断。 相似文献

身高作为一项重要的人体测量学特征,不仅有助于认识其他人类学特征和遗传风险因素,也是法医DNA表型研究的重要内容。对于身高的准确推断可以更完整地提供嫌疑人的表型信息,为案件侦破提供帮助。近年分子生物学技术和生物信息学快速发展,身高相关的遗传学研究也取得一定研究进展。本文主要从遗传变异和表观遗传两方面阐述身高推断的研究进展,并对今后研究方向进行展望。 相似文献

犯罪现场中人体生物性物质来源鉴定在重现犯罪过程方面发挥了重要作用,寻找特异性遗传标记鉴定人体不同生物性物质来源是近年来法医学工作者研究的重点和难点。本文就目前研究较多的用于人体生物性物质来源鉴定的遗传标记进行综述,包括DNA甲基化、mRNA、microRNA、微生物菌群、蛋白质等。通过比较不同种类遗传标记鉴定人体生物性物质来源的原理和方法,发现人体不同生物性物质来源的鉴定都有其最适合的遗传标记种类,并且可以采用单一遗传标记或联合多种遗传标记进行检验。尽管目前各法医学实验室无统一的标准和方法鉴定人体生物性物质来源,但研究开发一系列成熟可靠的方法区分人体不同生物性物质,进而发挥其法庭证据作用,将是未来的发展方向。 相似文献

Estimation of stature from foot and shoe measurements using multiplication factors is well known. It is a simple method and it is used very frequently as a ready reckoner in forensic anthropology. However the individual error is quite large. In the present work an attempt has been made to evolve revised multiplication factors to reduce this error so that this method (multiplication factor) can be used more effectively with smaller error. 相似文献

Stature is a fundamental anthropometric character to trace the biological profile of a person. In some cases, when dismembered or mutilated bodies are discovered in a forensic context, it is essential to estimate stature from single districts of the body. Nevertheless, to date and worldwide, there are only few population-specific studies on stature estimation from leg length and none of them concerns modern populations in southern Europe. We attempted to fill this gap, focusing on the estimation of stature from the length of the tibia in a Mediterranean population (Italians). We carried out the current study on a sample of 374 Italian university students of both sexes (age range: 19.9–34.4). Both, actual stature and percutaneous length of tibia were measured and new equations were developed for stature estimation. We tested separate regression equations for each sex, as well as an equation for remains, whose sex is unknown. To assess their reliability, the equations were tested on a holdout sample of 30 individuals from the same population. Moreover, results of new specific linear regression equations were compared to others from the literature. We demonstrated that the newly proposed formulae (for males and combined sexes) and the ones by Olivier (for females) provided the most reliable estimations of stature for southern Europeans. 相似文献

代谢组学是运用色谱、质谱、核磁共振(NMR)、毛细管电泳(CE)等技术对细胞、体液和器官等样品中的代谢物进行分离、纯化和检测,再用生物信息学的手段对所获得数据进行分析处理,从而得到一个或一组生物标记物信息的一门新兴学科。本文通过分析近年来有关代谢组学研究的文献报道,从历史渊源、概念、优点、分析方法、应用研究、存在问题及发展机遇、专业期刊和网站等方面对其进行综述,并根据现有研究对其在法医学各专业的应用作以展望,相信其能为法医学各专业和法医学鉴定提供一条新的研究思路。 相似文献
