复旦大学生命科学院遗传工程系三年级学生李辉在卢大儒、金力两位教授指导下,对“指间区纹的进化和遗传”进行了研究,在国内外首次发现人的手掌皮肤纹路与人的基因和智商有关,由单一基因起决定作用,并且存在单基因遗传。这一发现推翻了人体肤纹由多基因遗传的经典学说。受到著名的遗传学家、中国科学院院士谈家桢教授的高度评价,认为该项研究已达到国际先进水平。所谓指间区纹是指与手指相连的手掌部分的花纹。它比其它肤纹变化多样,又比指纹等的观察分析简单,因此特别适合作为肤纹的模式型,为肤纹的各项研究提供突破口。李辉调查了…  相似文献

中国人肤纹研究 Ⅰ.汉族10项肤纹参数正常值的测定   总被引:17,自引:2,他引:15  
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。  相似文献

Dermatoglyphics of 100 phenylketonurics and 200 controls matched for ethnic origin and sex were compared. The present study of dermatoglyphics in phenylketonurics is consistent with results showing that single gene disorders have fewer and less striking anomalies of ridge development than diseases with gross chromosomal defects.Analysis revealed a decreased frequency of whorl patterns on the finger tips and a wider mean summed atd angle among affected females as compared to normal females. The males showed no significant differences. Limited as they were to one sex, the differences seem unlikely to be attributable to the effect of the phenylketonuric gene.This research was supported by the Minnesota Association for Retarded Children, The Graduate School of the University of Minnesota and United States Public Health Service Grant Number HD 01507-01.  相似文献

Studies have been conducted with the arginase (l-arginine amidinohydrolase, EC 3.5.3.1) of two legumes: jack bean, Canavalia ensiformis (L.) DC., a l-canavanine-containing plant and soybean, Glycine max, a canavanine-free species. Analyses of the arginase obtained from gradient-purified mitochondria of these legumes revealed that the arginine-dependent (ADA) and canavanine-dependent activities (CDA) were localized within this organelle.  相似文献

A total of 203 couples with unexplained habitual abortions and 364 consecutive normal puerperae along with their live-born babies were studied. The analysis of wife-husband joint ABO blood group distribution in couples with habitual abortion showed an excess of A incompatible mating type and a defect of B incompatible type as compared with expected proportions assuming random mating. The joint wife-husband ABO blood group distribution was further analysed in relation to the adenosine deaminase (ADA) genotype. A defect of O-A and A-O couples when the wife carries the ADA*1/*1 genotype and the husband carries the ADA*2 allele, and a defect of O-O and A-A when the wife carries the ADA*2 allele were observed. In the sample of normal puerperae, analysis of the joint mother-newborn ABO distribution in relation to the ADA genotype showed a pattern similar to that observed in couples with habitual abortion, i.e. there is a defect of O-A and A-O when the mother carries the ADA*1/*1 genotype and the newborn carries the ADA*2 allele and a defect of O-O and A-A types when the mother carries the ADA*2 allele. Altogether the data suggest an early loss of O-A and A-O zygotes when they carry the ADA*2 allele and an early loss of O-O and A-A zygotes when the mother carries the ADA*2 allele resulting in a deficit of these zygotic classes among both spontaneously aborted fetuses and live-born infants. The pattern of association observed in the mother-fetus type O-A (incompatible according to conventional terminology) appears similar to that observed for the reciprocal A-O type (compatible according to conventional terminolgy). Therefore strictly conventional immunological mechanisms cannot explain the whole pattern of associations. Cell to cell interactions involving ABO antigens may have an important role at implantation: ADA, through the control of local adenosine concentration, could modulate these interactions influencing the probability of successful implantation.  相似文献

ObjectiveTo explore the prevalence of gestational diabetes mellitus (GDM), defined by the previous criteria of the American Diabetes Association (ADA), as well as the criteria suggested by the International Association of Diabetes and Pregnancy Study Groups (IADPSG), in an unselected group of urban Mexican pregnant women and to analyze the frequency of large for gestational age (LGA) newborns in this same group of women with use of both diagnostic criteria.MethodsA cross-sectional study included 803 consecutive Mexican urban women with a singleton pregnancy, without concomitant diseases and no prior history of GDM, who underwent a 2-step screening protocol for diagnosis of GDM at admission to prenatal care.ResultsThe ADA criteria identified 83 women (10.3%) whereas the IADPSG criteria diagnosed 242 women (30.1%) having GDM (P = .0001). Fasting glucose concentrations during the 100-g 3-hour oral glucose tolerance test were abnormal in 116 women (14.4%) and in 160 women (19.9%) on the basis of ADA and IADPSG criteria, respectively (P = .004). The frequency of LGA newborns was 7.4% based on IADPSG criteria and 6.0% based on ADA criteria—no significant difference (P = .64).ConclusionWith use of the IADPSG criteria, the prevalence of GDM increased almost 3-fold in comparison with that for the ADA criteria. Nevertheless, no significant difference was found in the prevalence of LGA newborns. (Endocr Pract. 2012;18:146-151)  相似文献

The Computational Modeling in Biology Network (COMBINE) is an initiative to coordinate the development of community standards and formats in computational systems biology and related fields. This report summarizes the topics and activities of the fourth edition of the annual COMBINE meeting, held in Paris during September 16-20 2013, and attended by a total of 96 people. This edition pioneered a first day devoted to modeling approaches in biology, which attracted a broad audience of scientists thanks to a panel of renowned speakers. During subsequent days, discussions were held on many subjects including the introduction of new features in the various COMBINE standards, new software tools that use the standards, and outreach efforts. Significant emphasis went into work on extensions of the SBML format, and also into community-building. This year’s edition once again demonstrated that the COMBINE community is thriving, and still manages to help coordinate activities between different standards in computational systems biology.  相似文献

Congenital dyserythropoietic anemias (CDA) are genetic disorders characterized by anemia and ineffective erythropoiesis. Three main types of CDA have been distinguished: CDA I and CDA III, whose loci have been already mapped, and CDA II (MIM 224100), the most frequent among CDAs, which is transmitted as an autosomal recessive trait and is known also as "HEMPAS" (hereditary erythroblast multinuclearity with positive acidified serum). We have recruited a panel of well-characterized CDA II families and have used them to search for the CDA II gene by linkage analysis. After the exclusion of three candidate genes, we ob-tained conclusive evidence for linkage of CDA II to microsatellite markers on the long arm of chromosome 20 (20q11.2). A maximum two-point LOD score of 5.4 at a recombination fraction of .00 was obtained with marker D20S863. Strong evidence of allelic association with the disease was detected with the same marker. Some recombinational events established a maximum candidate interval of approximately 5 cM.  相似文献

A new type of cellulose derivative, cellulose dehydroabietate (CDA), was synthesized by the O-acylation reaction of cellulose with dehydroabietic acid chloride (DHAC) using ionic liquid 1-butyl-3-methylimidazolium bromide ([bmim]Br) as a solvent and 4-dimethyl-aminopyridine (DMAP) as a catalyst. The resulting CDA was characterized by means of FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), and elemental analysis. Also, some properties of CDA were determined. These results showed that CDA has better solubility, water-repellency, and resistance to acids and bases than raw cellulose, and these properties increase with the DS of CDA.  相似文献

Dermatoglyphics of schizophrenics, patients with Down's syndrome and mentally retarded males were compared with those of normal Australian Europeans. A computer programme of multivariate analysis of fifteen dermatoglyphic features was utilized. This analysis produces two significant variates of each of the populations plotted in two-dimensional space. The distance, measured in arbitrary units, between any two populations was studied for its significance. It was noticed that the patients with Down's syndrome separated significantly from the rest of the groups. The importance of multivariate analysis in the study of dermatoglyphics in comparing two or more populations is discussed.  相似文献
