TL;DR: The results of this investigation confirm the results of previous investigations on genetic red cell enzyme markers, i.e. a relatively high genetic heterogeneity of Corsicans compared with other Mediterranean populations.
Abstract: By this investigation, the AA. want to contribute to the knowledge on the genetic characteristics of the Corsican population. The distribution of seven genetic serum protein markers (PI, TF, GC, ORM, HP, C3, PLG) was analized in a sample of 291 individuals coming from the central and northern areas of Corsica, i.e. from Corte and Bastia. The two samples do not show significant differences in the distribution of the genetic markers under study. The comparisons with other Mediterranean populations confirm the results of previous investigations on genetic red cell enzyme markers (Vona et al. 1995), i.e. relatively high genetic heterogeneity of Corsicans compared with other Mediterranean populations

TL;DR: The interaction between nutritional status, estimated by using Body mass index, and fertility outcome was tested in two female samples from Northern Namibia and it turned out, that !Kung San undernourished females had significantly more total and surviving offspring than well-nourishing and overweight females of these population.
Abstract: The interaction between nutritional status, estimated by using Body mass index, and fertility outcome was tested in two female samples from Northern Namibia. It turned out, that !Kung San undernourished females had significantly more total and surviving offspring than well-nourished and overweight females of these population. In contrast within the Kavango group well-nourished females had the highest reproductive success. These group specific differences can be interpreted as special reproductive strategies to maximize the reproductive success under different ecological conditions.

TL;DR: The results indicate that the values of kinship are not associated with the geographic distances, and the kinship values between pairs of populations show some preferential relationship and an evident differentiation between Gavoi and Bitti.
Abstract: Summary: Temporal changes in the matrimonial structure of four Sardinian populations (Bitti, Lula, Lode and Gavoi) have been studied The endogamy rates and the average marriage distances indicate that the four villages experienced a long period of isolation Only in recent decades endogamous marriages have fallen shortly The trends of marital isonymy and inbreeding, evaluated both from isonymy and dispensation for consanguineous marriages, are similar to those of endogamy The kinship values between pairs of populations show some preferential relationship (Bitti-Lode, Lode-Lula) and an evident differentiation between Gavoi and Bitti The results also indicate that the values of kinship are not associated with the geographic distances The possible impact of the matrimonial structure on the genetic structure and the relationships among the studied populations will be examined in further investigations, in which the genetic markers will be considered Zusammenfassung: In vier sardischen Bevolkerungen (Bitti, Lula, Lode und Gavoi) wurden die zeitlichen Veranderungen in den Heiratsverhaltnissen untersucht Die Endogamieraten sowie die durchschnittlichen Entfernungen bezuglich der Herkunft der Ehepartner lassen fur alle vier Bevolkerungen eine zeitlich lange Isolation erkennen Erst in den letzten Jahrzehnten hat die Haufigkeit endogamer Heiraten deutlich abgenommen Die Trends bezuglich „marital isonymy" und „inbreeding", die anhand der Isonymie und der bei Verwandtenehen erforderlichen Heiratsgenehmigungen ermittelt wurden, entsprechen denen fur die Endogamie Die „kinship values" zwischen den paarweise verglichenen Bevolkerungen zeigen charakteristische Beziehungen, so zwischen Bitti und Lode sowie zwischen Lode und Lula, andererseits eine deutliche Differenzierung zwischen Gavoi und Bitti Die Ergebnisse lassen schlieslich auch erkennen, das die „kinship values" nicht mit den geographischen Entfernungen assoziiert sind Die mogliche Bedeutung dieser Heiratsverhaltnisse fur die genetische Struktur dieser Bevolkerungen sowie fur die genetischen Beziehungen zwischen ihnen wird anhand genetischer Marker in weiteren Untersuchungen analysiert

TL;DR: Dental morphology as adjudged from dental casts of children (boys and girls) 6-13 years of age from four Bedouin tribes of Southern Sinai and a mixed group designated as "other tribes", showed a higher rate of asymmetry in molars than in the mandible.
Abstract: Data are presented on dental morphology as adjudged from dental casts of children (boys and girls) 6-13 years of age from four Bedouin tribes of Southern Sinai (Gebeliya, Muzeina, Hamada and Aliquat) and a mixed group designated as "other tribes", (Awlad Said, Gararsha, Sawalcha, Haweitat and Beni-Wassal). Alginate was the impression material used and the casts were made of artificial stone poured into the irreversible hydrocolloid impression. A total of 352 casts were available for study. In the maxilla, 29 dental discrete traits of permanent teeth and 2 traits of deciduous teeth were observed, and in the mandible, 24 traits of permanent teeth and 2 traits of deciduous teeth; in all, 57 traits were observed. Only clear traits were considered. From the studied 57 traits only 30 morphological traits were used for the estimation of the asymmetry. Total symmetry was observed in 2 mandibular teeth and traits: a) Lateral incisor-LI-slight inclination; b) Canine-Cn-no lingual cingulum and in 3 maxillary teeth and traits a) Central incisor-CI-slight convexity of labial profile curvature; b) First premolar-PM1-intercuspal distance more than 3 mm; and c) Second molar,-M2-pit groove pattern similar to the first molar. Low values of asymmetry (1-5.1%) were observed in traits describing outline form and shape, surface outline, and number of cusps in three maxillary and two mandibular teeth (nine discrete traits). High values of asymmetry (12.7-37.0%) were observed regarding traits describing styles on slopes, ridges, pits, grooves and lingual tubercles in three maxillary and one mandibular teeth (15 discrete traits). The high rate in molars was higher than that in the incisors. A higher rate of asymmetry occurred in the maxilla than in the mandible.

TL;DR: By comparing the methods for age estimation using the number of teeth or the roentgenological method from Demirjian et al. (1973) it could be shown that both methods lead to comparable results in the first period of permanent teeth eruption.
Abstract: Based on the process of tooth eruption in children of Jena during the first period of erupting permanent teeth secular changes of the dentition were investigated and the topicality of the current tables for dental age were checked. Mean age of eruption was computed for the individual types of teeth and for each sex in Jena's children and curves for eruption were constructed. On this basis population-specific standards for the dental age were calculated and the children were subdivided into "late, normal or early teether". By comparing the methods for age estimation using the number of teeth or the roentgenological method from Demirjian et al. (1973) it could be shown, that both methods lead to comparable results in the first period of permanent teeth eruption.

TL;DR: The detection of unchanged nicotine indicates that nicotine remained present in bones up centuries, and points out the assumption that nicotine was used antemortem.
Abstract: Human remains from excavation sites in southern China, dated from 100 to 10,000 years, were investigated for nicotine. The nicotine concentrations were measured by radioimmunoassay. Consequently, the values measured represent the sum of nicotine and its metabolites. Positive results were observed in 25.9% (mean values of all samples). The concentrations ranged from 11.8 to 474.2 ng/g sample. From the excavation sites with the highest number of individuals, Chongtong (18 individuals) were 38.9%, and from the site Leigund (21 individuals) were 28.6% from the samples nicotine positive. The highest level with 474.2 ng/g nicotine was found in a sample dated 100 years. It is possible, that this individual was smoker. In addition the samples were investigated also by gas chromatography/mass spectrometry. The GC/MS indicated the presence of nicotine and its primary metabolite, cotinine. The presence of cotinine points out the assumption that nicotine was used antemortem. The detection of unchanged nicotine indicates that nicotine remained present in bones up centuries.

TL;DR: Keratins extracted from the hair of several mammals were characterized by SDS-PAGE and isoelectric focusing and differences were found in the intensity of polypeptide bands in the acidic pH range (< 5.1).
Abstract: Keratins extracted from the hair of several mammals were characterized by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and isoelectric focusing (IEF). By SDS-PAGE, most differences between species were detected in the position and intensity of polypeptide bands with MW in the range 30-10 KDa (high sulphur keratins, hair matrix proteins, HMP). By IEF, differences were found in the intensity of polypeptide bands in the acidic pH range (< 5.1). Electrophoretic techniques could therefore have a taxonomic usefulness.

TL;DR: It was showed that though Chinese females had less digital hair on the hands than Chinese males, they showed a much larger variety of patterns of digital hair distribution than males.
Abstract: Hair distribution on the dorsum of phalanges of the hand was studied on 302 Chinese subjects (134 males and 168 females) randomly selected from the residents of Kota Bharu, Malaysia. Proximal phalangeal hair was seen on the dorsum of both hands in 99.3% of male subjects but in only 85.1% of female subjects. Chinese females showed a significantly lower (p < 0.05) incidence of proximal phalangeal hair on the hands than Chinese males. Comparison with other racial groups showed that Chinese females had significantly less (p < 0.05) hair on the proximal phalanges of the hands than Malay and African (Nigerian) females. The least common digital combination of proximal phalangeal hair in female subjects was the presence of proximal phalangeal hair only on the fourth digit (ring finger) and was noted in 0.6% of subjects. This has not been reported before. The frequency of middle phalangeal hair (MPH) distribution in Chinese falls between that in Malays and in Japanese which is probably explained by the fact that all these three racial groups originate from Asia. A study of digital combination of MPH in Chinese showed that the most common and the least common combinations in the Chinese differ considerably from those in other races. A total of 16 patterns of hair distribution was noted on the dorsum of the phalanges of the hands in Chinese subjects. Our study showed that though Chinese females had less digital hair on the hands than Chinese males, they showed a much larger variety of patterns of digital hair distribution than males.

TL;DR: Following the anthropometric method of Heath-Carter (1967) individual somatotypes of a sample of 1260 school children living in Bilbao and aged between 14-19 years have been investigated, finding that in both sexes, somatotype varies with age.
Abstract: Following the anthropometric method of Heath-Carter (1967) individual somatotypes of a sample of 1260 school children (605 boys and 655 girls) living in Bilbao and aged between 14-19 years have been investigated. Age differences of the somatotype components and sexual dimorphism of the physique were also analyzed. In both sexes, somatotype varies with age. The main factor for these variations of the somatotype is in the boys the endomorphy, and in the girls the mesomorphy. The mean somatotypes of the total sample are in boys central (3.9-3.9-2.7) and in girls mesomorphic-endomorphic (5.3-3.1-2.3).

TL;DR: The genotype distribution and the allele frequency of the VNTR locus D1S80 have been studied in a population of 378 unrelated Germans living at Düsseldorf and it is demonstrated that the locus is highly polymorphic with an observed heterozygosity of 75.66%.
Abstract: Hypervariable loci within the human genome are useful tools in several disciplines: for example in forensic medicine (paternity testing and forensic identification). One of these genetical markers is located at chromosome 1 and is called D1S80 (MCT118). The genotype distribution and the allele frequency of the VNTR locus D1S80 have been studied in a population of 378 unrelated Germans living at Dusseldorf. The determination of genotypes has been carried out by using the polymerase chain reaction and subsequent analysis of the amplified products by polyacrylamide electrophoresis followed by silver staining. The data demonstrate that the locus is highly polymorphic with an observed heterozygosity of 75.66%. The frequency distribution found does not meet Hardy-Weinberg expectations. We think that this is not astonishing because we found only 80 of the possible 231 phenotypes (alleles 16-34, 36-37, without anodal and cathodal variants). So before using the D1S80 data in forensic analyses and paternity tests a larger data base has to be established. The data of the Dusseldorf sample are compared with data of studies on other populations.
TL;DR: A population study was carried out on Caucasians from Düsseldorf using the short tandem repeat (STR) system HumVWA (von Willebrand factor; locus 12p12-12pter; intron A) and no deviations from the Hardy-Weinberg equilibrium could be observed.
Abstract: A population study was carried out on Caucasians from Dusseldorf using the short tandem repeat (STR) system HumVWA (von Willebrand factor; locus 12p12-12pter; intron A). After amplification, electrophoresis and silver staining 9 alleles could be detected in the sample of 304 unrelated individuals. No deviations from the Hardy-Weinberg equilibrium could be observed. The results were compared with other population studies.
TL;DR: In all the three groups, in all household membership categories, the intake of cereal is higher than the recommended intake, but the male-female differences in net intakes are higher in peak season than in lean season.
Abstract: Food may not be equitably distributed within the household. The distribution depends on some factors, one of which is availability of food. The generalised proposition of gender bias against women in the distribution of food in South Asia has been examined here in three culturally contrasting population groups in two seasons, viz. lean and peak. The result shows that in all the three groups, in all household membership categories, the intake of cereal is higher than the recommended intake, but the male-female differences in net intakes are higher in peak season than in lean season.

TL;DR: In Medzev, a village located in South-Eastern Slovakia, the secular variation of two indices of genetic isolation has been studied and it could be seen that this village was highly isolated till the beginning of the 20th century.
Abstract: In Medzev, a village located in South-Eastern Slovakia, the secular variation of two indices of genetic isolation has been studied. It could be seen that this village was highly isolated till the beginning of the 20th century. Both indices show a tendency to increase in the first five decades of this century. For the entire period from 1766-1950 the coefficient of inbreeding estimated by the method of isonymy was found to be F = 0.0074 with different ratios of random (Fr) and non-random (Fn) components in particular periods. The coefficient of inbreeding estimated from the ecclesiastical dispensations for marriages comes to F = 0.0019. The genetic significance of the changes in the population structure of this village will be analyzed in further studies.
TL;DR: The significant finding of the study is that the palmar interdigital ridge-counts follow normal distribution and that they are useful in studying inter-population affinities.
Abstract: Bilateral palmar prints of 2927 males of 20 endogamous Dhangar castes of Maharashtra, India, were studied for the distributions of a-b, b-c and c-d interdigital ridge-counts. The ridge-counts have been utilized for examining the inter-population affinities among the Dhangar castes. The distribution of a-b ridge-counts is symmetrical and normal in Dhangar castes. The distributions of b-c and c-d ridge-counts on both palms also show (nearly) normal distribution, but with a tendency of negative skewness and platykurtosis in c-d ridge-count. Equality of means and standard deviations depict significant heterogeneity. The decreasing order of magnitude of means of interdigital ridge-counts is a-b > c-d > b-c among all the Dhangar castes. Intercaste comparisons reveal a great deal of variations in all ridge-counts. The pattern of relationship between the Dhangar castes based on the three ridge-counts is in agreement with the expected patterns of affinities based on the known ethno-historical evidence. The significant finding of the study is that the palmar interdigital ridge-counts follow normal distribution and that they are useful in studying inter-population affinities.

TL;DR: In a sample of 410 Families eight body characteristics were examined concerning the appearance of heterosis effects in newborns and the best criteria for classification proved to be the categorization by morphological typology of the parents.
Abstract: In a sample of 410 Families eight body characteristics were examined concerning the appearance of heterosis effects in newborns. Distance between the parents' birthplaces, ABO blood groups and morphological typology were used as measures for the genetic differences of the parents. The t-test was applied to test differences between newborns of different distance groups of homogenic and heterogenic parents. Differences were scarcely seen. The best criteria for classification proved to be the categorization by morphological typology of the parents.
TL;DR: The distribution of glyoxalase 1 (GLO1) phenotypes in eight geographical regions of Turkey was studied and the GLO1*1 allele frequency varies from 0.3630 to 0.4118, which is in good agreement with the previously estimated range of variability.
Abstract: The distribution of glyoxalase 1 (GLO1) phenotypes in eight geographical regions of Turkey was studied. The GLO1 * 1 allele frequency varies from 0.3630 to 0.4118, which is in good agreement with the previously estimated range of variability. Excess numbers of heterozygotes compared to the Hardy-Weinberg equilibrium were observed in all regions. The reasons of this requires further investigations
TL;DR: Le « tamisage » (« Siebung ») fut conceptualise par Richard Thurnwald, au debut de 1904, pour decrire les processus sociaux, evoques par la migration and le contact de differents groupes culturels.
Abstract: Le « tamisage » (« Siebung ») fut conceptualise par Richard Thurnwald (1869-1954). Il developpa ce concept, au debut de 1904, pour decrire les processus sociaux, evoques par la migration et le contact de differents groupes culturels. Desormais le « tamisage » permet d'attribuer certaines positions dans les societes aux personnes ayant des attributs speciaux. Chaque societe possede son propre systeme de valeurs qui peut etre soit conscient soit inconscient. Les effets des processus de « tamisage » peuvent concerner le changement genetique d'une population a long terme
TL;DR: Within the frame of an anthropobiological survey on some populations of Cameroon (1985-1991), Hb beta data were collected from numerous ethnic groups including Bakaka, Bamileke, Daba, Fali, Guiziga, Kanuri, Mada, Mafa, Mundang, Uldeme, Podokwo, Tali, Tupuri, Fulbe, Mandara, Ewondo and Bassa.
Abstract: Within the frame of an anthropobiological survey on some populations of Cameroon (1985-1991), Hb beta data were collected from numerous ethnic groups including Bakaka, Bamileke, Daba, Fali, Guiziga, Kanuri, Mada, Mafa, Mundang, Uldeme, Podokwo, Tali, Tupuri, Fulbe, Mandara, Ewondo and Bassa. Hb beta *S allele frequencies ranged from 0.008 +/- 0.003 (among Fali) to 0.152 +/- 0.020 (among Mandara) and 0.152 +/- 0.044 (among Podokwo), whereas Hb beta *S was found to be absent among Tupuri. Hb beta *C was observed among Bamileke (0.001 +/- 0.001), Fali (0.003 +/- 0.002), Fulbe (0.002 +/- 0.002), Mafa (0.005 +/- 0.005), Mundang (0.005 +/- 0.005), Tupuri (0.010 +/- 0.007) and Podokwo (0.015 +/- 0.015). The possible reasons for these variations in allele frequencies are discussed.
TL;DR: It could be shown, that in body measurements as well as in head measurements late teether seem to have a tendency to the smallest mean values, early teether show a tendencies to higher mean values.
Abstract: Body height, body weight and several head measurements from children with different dental age were compared. In addition, it was investigated, if the increasing rates in the body and head measurements in the separate dentition stages show a connection between the development of the body and the dentition. It could be shown, that in body measurements as well as in head measurements late teether seem to have tendency to the smallest mean values, early teether show a tendency to higher mean values. This trend is in girls clearer than in boys. The increasing rates of the body and head measurements differ in the separate dentition stages, but do not allow conclusions of the dentition process
TL;DR: A population study was carried out on 301 ethnic Germans from Düsseldorf (Northrhine Westphalia) using the short tandem repeat (STR) system HumF13B (Coagulation Factor XIIIB) and five different alleles were detected.
Abstract: A population study was carried out on 301 ethnic Germans from Dusseldorf (Northrhine Westphalia) using the short tandem repeat (STR) system HumF13B (Coagulation Factor XIIIB). Five different alleles were detected. No deviations from the Hardy-Weinberg equilibrium could be observed. In spite of the successfulness of the system only a few population data exist. A pooled sample from Northrhine Westphalia has to be used as preliminary database for forensic and anthropological purposes.

TL;DR: In a randomly selected sample of 1579 individuals, aging from 14 to 65 years and representing all the socioeconomic groups of Multan, age (Yr), height, height, weight, BMI, BMI and blood pressure were recorded.
Abstract: In a randomly selected sample of 1579 individuals (male = 1334 and female = 245), aging from 14 to 65 years and representing all the socioeconomic groups of Multan, age (Yr), height (cm), weight (kg), BMI (kg/m 2 ) and blood pressure (mmHg) were recorded. Height was measured on a Holtain portable stadiometer, weight on beam scale and blood pressure was recorded with sphygmomanometer as per auscultatory method. The correlation coefficient between different independent (age, height, weight and BMI) and dependent (SBP, DBP and MAP) parameters in male, female and total population were calculated and strong association between different parameters was observed (p < 0.001 or p < 0.05). The regression equations (simple and multiple) were worked out. The regression coefficient of different independent parameters with dependent parameters are higher in female except for height and age-weight and age-BMI had higher contribution in female as compared with that of male
TL;DR: The results show that while effects of religious practices do not seem to exist on the haematological traits considered, significant effects of rural/urban residence do.
Abstract: As a part of an ongoing multidisciplinary biomedical research programme, initiated by the Indian Statistical Institute in early 1976, entitled "Human Adaptability Programme", the present study was undertaken among the Lepchas of Kalimpong subdivision, Darjeeling district, West Bengal (India) to enquire at a micro-level into the possible relationship between the major sociocultural factors, viz. religious practices and rural/urban residence, on the one hand, and haematological traits such as haemoglobin level, haematocrit and anaemia, on the other. The results show that while effects of religious practices do not seem to exist on the haematological traits considered, significant effects of rural/urban residence do.

TL;DR: This paper analyzed deux populations of the region du Sud de l'Allemagne presentant un fort taux de mortalite infantile au 19 eme siecle, i.e., a mortalite fraction of the infantile fraction in the population catholique, l'autre protestant and aucun mariage entre des membres des deux confessions.
Abstract: Une mortalite infantile elevee, des differences regionales et le maintien des differences sur une longue periode apparaissent des le 19 eme siecles. Les modeles multifactoriels explicatifs de ce phenomene ont ete discutes et une grande importance a ete accordee aux facteurs sociaux. Les AA. analysent deux populations de la meme region du Sud de l'Allemagne presentant un fort taux de mortalite infantile au 19 eme siecle. Il apparait que le contexte etait similaire, les deux villages ayant de faibles differences au niveau de la taille demographique. Depuis la fin du 16 eme siecle, les deux villages se reclament de differentes confessions religieuses : l'un est catholique, l'autre protestant et aucun mariage entre des membres des deux confessions n'a eu lieu jusqu'a aujourd'hui. On note que la mortalite infantile fut plus elevee dans la population catholique. L'analyse de l'influence du nombre d'enfants par famille et de l'âge de la mere a la naissance des enfants confirme l'hypothese que les facteurs sociaux, fortement influences par la confession religieuse, sont les principaux facteurs expliquant les differences intercommunautaires
TL;DR: Genetic polymorphism of the PLG serum protein was examined in the Namibian !Kung San and Kavango (Bantu) populations by means of IEF technique and the distributions were within previously observed African PLG ranges.
Abstract: Genetic polymorphism of the PLG serum protein was examined in the Namibian !Kung San and Kavango (Bantu) populations by means of IEF technique. The two samples revealed very similar allele frequencies (!Kung San: PLG*A = 0.8351, PLG*B = 0.1649; Kavango: PLG*A = 0.8228, PLG*B = 0.1732 and PLG*M4 = 0.004). The Namibian distributions were within previously observed African PLG ranges. The effects of natural selection were also discussed.
