汉族人肤纹研究——男性七顶指纹参数正常值的测定

本文报道4300例汉族人男性七项指纹参数的正常值,特别是同一个体的十指指纹1001种组合的观察数据和期望频率,对进一步深人人类学、医学肤纹学,遗传学等方面的研究提供了一定的条件。     

西藏藏族起源初探——来自掌指纹的线索

本文采用分层整群抽样的调查方法捺印1183名藏族青少年的掌指纹, 分析掌指纹参数,然后与其他56个群体的掌指纹参数进行聚类分析, 进而从肤纹学角度探讨藏族的起源。发现藏族指纹以斗型纹为主(52.89%), 其次为箕型纹(42.95%), 弓形纹出现频率最低(4.16%); 总指嵴线计数为139.01(其中男性为144.75, 女性为133.87); atd角在男性为42.95°, 女性为43.28°。掌指纹参数聚类分析显示: 藏族与汉族和氐羌氏族的后裔(门巴族、普米族、羌族等)等我国北方人群聚在一起。因而从肤纹学角度推断藏族与汉族和氐羌氏族的亲缘关系较近, 而与印度人和孟加拉人的亲缘关系较远。     

肤纹与破案(上)

肤纹学是研究皮肤纹嵴的科学。皮肤纹嵴主要有指纹、掌纹、趾纹和蹠纹。另外还有近年来才引起人们注意的唇纹。肤纹学研究是在人类学、人类遗传学、医学、生物学、法庭科学等多个学科中展开的。肤纹在法庭科学中的应用,主要是指纹在犯罪现场的提取,以及对提取的指纹与嫌疑人和指纹档案中存档指纹的比对。肤纹学是法庭科学中应用最早的科学方法之一。至今,司法部门在认定罪犯方面,肤纹仍是最可信赖的证据之一。一、指纹破案的由来指纹在破案中所起的作用主要是个体识别。指纹的这种作用,由于在电影、电视、戏剧、小说等故事情节中的无数次应用,现在已是老少皆知了。指纹用于破     

躁狂抑郁症的肤纹学研究

躁狂抑郁症(简称躁郁症)的肤纹学异常,国内从未见报道。本文对140例躁郁症的手、足纹特征进行对照研究,现将结果报告如下。 对象和方法 (一)研究对象 系符合躁郁症临床工作诊断标准的140名住院病人,汉族,均为天津地区及河北省人。     

中国人肤纹研究 Ⅰ.汉族10项肤纹参数正常值的测定

我们的祖先对指纹早有观察,新石器时代陶器上的雷云纹即由指纹脱胎而来。在近代科学中,Galton(1892)首先提出指纹的系统分类。尔后Cummins等修订了肤纹分析方法。肤纹分析在医学上的应用首推Cummins,他最早描述了先天愚型患儿的肤纹特征。迄今大量的材料表明,异常肤纹组合可作为某些遗传病的辅助诊断指标。对我国人群的肤纹参数正常值,1933年Takeya曾有报道,近年来董悌忱、李崇高和王京美等人也进行了这方面的工作,但尚缺乏比较全面的肤纹参数正常值。本文报道1,040例汉族人10项肤纹参数正常值,为医学肤纹学和人类学研究提供基础数据。     

肤纹学视野中的中华民族

肤纹是灵长目特有的性状,在包括人类在内的灵长目动物的手掌、脚跖面上,布满了组成各种图案的皮肤嵴纹。不难理解,肤纹学就是对指纹、掌纹和足纹的科学研究。

Recent advances in the study of Kaposi's sarcoma-associated herpesvirus replication and pathogenesis

It has now been over twenty years since a novel herpesviral genome was identified in Kaposi's sarcoma biopsies. Since then, the cumulative research effort by molecular biologists, virologists, clinicians, and epidemiologists alike has led to the extensive characterization of this tumor virus, Kaposi's sarcoma-associated herpesvirus(KSHV; also known as human herpesvirus 8(HHV-8)), and its associated diseases. Here we review the current knowledge of KSHV biology and pathogenesis, with a particular emphasis on new and exciting advances in the field of epigenetics. We also discuss the development and practicality of various cell culture and animal model systems to study KSHV replication and pathogenesis.     

The structure, reproduction and taxonomy of Vidalia and Osmundaria (Rhodophyta, Rhodomelaceae)

Comprises species occurring mostly in subtidal habitats in tropical, subtropical and warm-temperate areas of the world. An analysis of the type species, V. spiralis (Sonder) Lamouroux ex J. Agardh, a species from Australia, establishes basic characters for distinguishing species in the genus. These characters are (1) branching patterns of thalli, (2) flat blades that may be spiralled on their axis, (3) width of the blade, (4) primary or secondary derivation of sterile and fertile branchlets and (5) position of sterile and fertile branchlets on the thalli. Application of the latter two characters provides an important basic method for separation of species into three major groups. Osmundaria , a genus known only in southern Australia, was studied in relation to Vidalia , and its separation from the Vidalia assemblage is not accepted. Species of Vidalia therefore are transferred to the older genus name, Osmundaria. Two new species, Osmundaria papenfussii and Osmundaria oliveae are described from Natal. Confusion in the usage of the epithet, Vidalia fimbriala Brown ex Turner has been clarified, and Vidalia gregaria Falkenberg, described as an epiphyte on Osmundaria pro/ifera Lamouroux, is revealed to be young branches of the host, Osmundaria prolifera.     

New or rare chromosome counts in Artemisia L. (Asteraceae, Anthemideae) and related genera from Kazakhstan

Fifteen chromosome counts of six Artemisia taxa and one species of each of the genera Brachanthemum, Hippolytia, Kaschgaria, Lepidolopsis and Turaniphytum are reported from Kazakhstan. Three of them are new reports, two are not consistent with previous counts and the remainder are confirmations of very scarce (one to four) earlier records. All the populations studied have the same basic chromosome number, x = 9, with ploidy levels ranging from 2x to 6x. Some correlations between ploidy level, morphological characters and distribution are noted.

Selection with two alleles and complete dominance

For a plant selection model with frequency-independent viabilities, fertilities and selfing rates, it is shown that apart from global fixation, for certain parameter combinations a protected polymorphism and facultative fixation (either allele may become fixed according to initial frequencies) may both occur. Facultative fixation requires different selling rates for the dominant and recessive type. Protection of the polymorphism requires resource allocation for male and female function. In this connection the problem of purely genetically caused population extinction is discussed.
For general frequency dependence and regular segregation, the chances for establishment of a completely recessive gene are compared to those of a completely dominant gene. It is proven that the process of establishment of the recessive gene, despite a fitness advantage, may be considerably endangered by drift effects if random mating prevails. The recessive gene may reach the same effectivity in establishment as a dominant gene, only if the recessive homozygote mates exclusively with its own type during the period of establishment.
