Electromyography of pongid shoulder muscles II. Deltoid, rhomboid and "rotator cuff"

Red cell antigen, serum protein and red cell enzyme groups were determined for a series of 1,821 individuals belonging to six language families in Western New Guinea. Three of the language families represent groupings of languages spoken by people in the swampy coastal plain of south central Western New Guinea, two belong to the Central Highlands and one to the Lake Plain area near the confluence of the Idenburg and Rouffaer Rivers. The distribution of genetic markers reveals similarities with other parts of New Guinea. The A₂ allele is absent in the ABO system, the frequency of Ns in the MNS system is very high as is the R₁ (CDe) allele in the Rh system. Hp¹ frequencies are high, and the transferrin allele Tf^D 1 is present as in other parts of New Guinea. In the red cell enzyme systems several alleles were detected which are characteristic of Papuan, and in some cases other Melanesian populations: these include MDH³, PGK⁴, PGK², PGM⁹₂, PGM¹⁰₂, as well as some very restricted alleles such as Peptidase B⁶ and Pep B². Three indices of genetic distance were computed. The most striking results are the genetic closeness of the Dani and Moni populations from the Central Highlands to the Asmat on the southern coastal plain, and the relative remoteness of the Awyu from the other south coastal populations. The results are discussed in terms of recent theories on the origin and dispersal of Papuan languages.     

Blood groups in the Chueta community (Majorcan Jews)

A sample of 443 Chuetas (descendents of Majorcan Jews) was typed for the ABO, Rh, Lewis, Duffy, MNSs, Kell and P blood groups. Significant deviations from the Hardy-Weinberg equilibrium were observed in the MNSs and Duffy systems with a deficiency of heterozygotes. The gene frequencies were compared with those of the Balearic non-Jewish populations and significant differences were found. Genetic distances and cluster analysis demonstrated that the Chuetas resemble more their neighboring non-Jewish populations than other Jewish populations. Discriminant analyses showed that the Chuetas and other Jews considered in this study do not resemble each other but their host peoples with respect to these markers.     

Distribution of the blood groups of the Norwegian lapps

Blood groups have been determined in samples from 423 Norwegian Lapps. The findings in the ABO, MNSs, P, Rh, Lewis, Duffy and Kidd systems are presented and compared with previous observations in various Lapp populations. Rather marked differences were observed between Lapps living in different geographical locations.     

Anthropometrical study of the Asmat (Irian Jaya).

An anthropometric study in the Asmat population, a coastal group of Papua living in the south-western part of Irian Jaya (Indonesian New Guinea) covered 318 subjects of both sexes, belonging to four different villages (Basim, Senggo, Ewer and Piramanak) of the Asmat region. The dimensions and derived indices, describing body, head and face morphology as well as body composition show the Asmat to be slender and muscular, with shoulders, chest and pelvis of medium dimensions and with long legs in relation to the trunk. They are dolichocephalic with narrow faces and rather large noses. Comparisons of the four Asmat groups indicate the importance of geographic position on size of the subjects and the similarities detected between the groups by discriminant and principal component analysis.     

Trace elements in human scalp hair and soil in irian jaya

Pb, Cd, and Ni contents were determined in the scalp hair of the Asmat of Irian Jaya (Indonesian New Guinea) on 35 adult subjects. These data are presented together with those of Al, Ca, Ti, Fe, Cu, Zn and Sr, which were determined in previous research on the same group. Hair samples were analyzed by EDXRS and ICP. Trace elements were also determined in 12 soil samples from the same area by EDXRS (Al, Si, K, Ca, Fe) and ICP (Cu, Sr, Ti), and by AAS (Cd, Ni, Pb). When hair element levels are compared and discussed with those of other New Guinea populations, acculturated and nonacculturated tropical groups, populations from Western countries and from polluted areas, and “recommended levels” in the literature, they greatly exceed Western levels and generally fit those of other New Guinea populations, stressing the importance of common environment, subsistence, and behavior. The results of soil analyses are consistent with the presence of those elements in hair, and their quantitative distribution follows a common trend. Metal mobility in soil, patterns of absorption, and transfer from soil to plants and to humans are considered here.     

Blood groups and HLA antigens in patients with abdominal aortic aneurysms

Frequencies of blood groups (ABO, Rh, MNSs, P, Kell, Lewis and Duffy) and HLA antigens were studied in a series of patients from northern Sweden with abdominal aortic aneurysms. The following significant differences from the controls were found: a decreased frequency of the Rh-negative blood group and increased frequencies of the Kell-positive and MN blood groups. Previously reported associations with the ABO and Rh systems were not confirmed.     

Genetic polymorphisms in the Kuwaiti Arabs

Blood samples were collected from 162 Kuwaiti Arabs. These samples were typed for the ABO, MNSs, Rh, Kell and Duffy blood group systems, serum protein haptoglobins, the red cell isoenzymes acid phosphatase, phosphoglucomutase (locus 1), adenylate kinase, 6-phosphogluconate dehydrogenase, and the lactate and malate dehydrogenase variants. Comparisons were made with serological findings for other Arab populations in the Arabian peninsula.     

Red cell antigen, serum protein and red cell enzyme polymorphisms in Karkar Islanders and inhabitants of the adjacent North Coast of New Guinea

Blood samples from the Waskia and Takia populations of Karkar Island, Papua New Guinea, and other nearby mainland populations, were tested for genetic variation in blood group, serum protein and red cell enzyme systems. Polymorphic variation was present in the ABO, P, MNS, Rh, Lewis, Duffy, Kidd and Gerbich blood group systems, in the Hp and Tf serum protein systems, and in the acid phosphatase, 6-PGD, ADA, PGM, MDH, and G-6-PD enzyme systems. A small number of variants was found in other systems: there were 4 Lu(a+), 1 Kp(a+), 2 C variants in the acid phosphatase system, 6 LDH variants, 1 ADA3-1 and 1 AK2-1 sample. All samples were negative for the red cell antigens Cw, Vw, He, K, Jsa, Dia, Wra, Rd and Marriott, and no variation was observed in the PHI enzyme system. The results are discussed in relation to those obtained on other Papua New Guinea populations.     

Genetics of Caucasian population: distribution of various immunological and biochemical markers in western Georgia

The distribution of genetic markers of blood groups (ABO, Rhesus, MNSs, P, Duffy, Kell-Cellano), plasma proteins (Hp, Gc, Tf, C'3) and red-cell enzymes (AcP, EstD, GLO-1), and also ABH secretion among 10 populations of Western Georgia has been studied. The common characteristic of distribution of gene frequencies for the markers studied was obtained as a whole in Georgia. The Georgians were compared for these markers with some populations of the Caucasus, Europe and West Asia. Among Caucasian populations, Georgians are most similar to Abkhasians. According to some systems, Georgians are close to European groups (ABO, Dubby, GLO-1, EstD), while they are similar to West-Asian groups, as judged by other systems (ABH secretion, AcP). According to Rhesus and MNSs systems, Georgians differ both from populations of Europe and from populations of West Asia.     

Comparison of erythrocyte markers gene frequencies in different populations

A comparison of erythrocyte markers (ABO, Rh system) gene frequencies was done by bar code diagrams in populations of variable ethnic origin. The results from missions for the development in Far East Asia (China, Indochina, New Guinea) were compared to well known gene frequencies of the populations living in other regions: inhabitants of the islands of the Pacific ocean, Europeans of New Zealand and Western Europe (France), Europeans of North America, Ameridans of Peru and Bolivia, Somalians of Africa. Polymorphism was observed in immense country very peopled, monomorphism was found in small and isolated region but polymorphism existed in tribes living in very isolated islands.     

Variation in the gene frequencies of three generations of humans from Monterrey, Nuevo León, Mexico

Allele frequencies for the ABO, Rh, MNSs, Duffy, Kidd, Lutheran, P and Lewis blood group systems in 207 persons whose 4 grandparents were born in the Monterrey Metropolitan area (MMA), grouped into 3 generations, were ascertained along with other related population from the MMA, Mestizos from Saltillo, Coahuila and Tlaxcala, and from the populations thought to have contributed to their genetic constitution (native Mexican Indians and Spanish). Genetic admixture and distance estimates were calculated. Gene frequencies of the three generations from MMA are intermediate to those of the ancestral populations, indicating that they are Mestizo but with a genetic structure different from Mestizos of Saltillo and Tlaxcala. Both genetic admixture and distance estimates indicate that the oldest generation exhibits the greatest Spanish influence which decreases in the youngest generation and in the other MMA populations as a result of the immigration from the central states of Mexico.     

The genetic demography of the Gainj of Papua New Guinea. I. Local differentiation of blood group,red cell enzyme,and serum protein allele frequencies

Allele frequencies are reported for 19 blood group, red cell enzyme, and serum protein loci (ABO, Rh, MN, Hb-A, LDH-A, LDH-B, SOD, PGM-1, PGM-2, 6PGD, GPT, ESD, ADA, ACP, PGK, MDH, Alb, Hp, and Tf) determined from 310 blood samples collected among the Gainj, a small population of tribal horticulturalists from highland Papua New Guinea. Fourteen of these loci display genetic variants, and ten of them are sufficiently polymorphic to permit a preliminary analysis of Gainj population structure. Patterns of variation among subdivisions of the population are analyzed using an approach analogous to a multivariate analysis of variance with unbalanced design, and weighted genetic distances are extracted from the results. The distance analysis indicates that patterns of genetic variation within this population reflect the geographical distribution of subdivisions, as well as subdivision size and movement among subdivisions. A parallel analysis of the Gainj and two other tribal groups from highland New Guinea, the Murapin Enga and the Simbai Valley Maring, suggests that the Gainj are both genetically divergent from neighboring populations and internally highly differentiated.     

Red cell antigen, serum protein and red cell enzyme polymorphisms in Eastern Highlanders of New Guinea

A series of 1,187 blood samples from eight population groups in the Eastern Highlands of Papua New Guinea were tested for genetic variation in blood groups, serum proteins and red cell enzyme systems. The populations belonged to the language groups Gahuku-Asarc-Bena Bena, Kamano, Yagaria, Keiagana, Fore, Agarabe, Auyana and Tairora. Polymorphic variation was found in the ABO, MNS, P1, Rh, Hp, Tf, SEP, 6-PGD, ADA, MDH, and PGM genetic systems. East to West variation was shown in the language groups; the O, S, R2, and R0 genes increase in frequency from East to West and the A, R1, and M genes decrease in the same direction. In the East higher frequencies were found for the Du antigen, for the PGM21 gene and for a PGM second locus variant. The MDH 3 variant was found in all the populations, its highest value being in the Tairora.     

The diego blood groups: A genetic linkage analysis

Data are presented which show that the Diego blood groups are not part of the Dombrock or Yt blood group systems and that the locus controlling Di is not closely linked to the loci controlling ABO, Fy, Jk, Kell, MNSs, Rh, Gm, Inv, AcP,ADA, PGD, and UMPK.     

Genetic studies on the Asmat population (Irian-Jaya, Indonesia)

The Asmat are a population of about 35,000 people living on the South-West coast of Irian-Jaya (Indonesia; New Guinea). This paper presents the results of enzyme group and serum protein group typings in a sample of Asmats living in the coastal region around Agats. Red cell enzyme polymorphisms (EaP, PGM1, 6-PGD, EsD, ADA and AK) could be typed in 154 blood samples, serum protein polymorphisms (Ge, alpha 1-AT, PLG, Tf and Hp) in 160 blood samples. The results of this study are discussed in detail.     

Balanced hereditary polymorphism and the mortality from cardiovascular diseases in the populations of 17 countries of Europe. I. A correlation analysis

The correlation analysis of ratios between six polymorphic genetic systems (ABO, MNSs, Rh, Hp, Gm, HLA) and mortality from ishemic heart disease, brain vascular lesions, and hypertensive disease in 17 European populations has been made. A statistically significant correlation has been established between the populational frequency of most of the 50 phenotypes and genes under study, and mortality. The qualitative structure of correlations and their quantitative expression depend on the cause of death, age and sex. The possible mechanisms of relationship between the genetic populational differences and mortality from cardiovascular diseases are discussed.     

The peopling of New Guinea: evidence from class I human leukocyte antigen.

This study utilizes newly developed direct DNA typing methods for human leukocyte antigens (HLA) to provide new information about the peopling of New Guinea. The complete polymorphism of eight Melanesian populations was examined. The groups included were highlanders, northern and southern highlands fringe populations, a Sepik population, northern and southern coastal New Guinea populations, and populations from the Bismarck Archipelago and New Caledonia. The study concluded that, based on HLA and other evidence. Melanesians are likely to have evolved largely from the same ancestral stock as Aboriginal Australians but to have since differentiated. Highlanders are likely to be descendants of earlier migrations who have been isolated for a long period of time. Northern highlands fringe and Sepik populations are likely to share a closer common ancestry but to have differentiated due to long term isolation and the relative proximity to the coast of the Sepik. Southern fringe populations are likely to have a different origin, possibly from the Gulf region, although there may be some admixture with neighboring groups. Coastal populations have a wider range of polymorphisms because of the genetic trail left by later population movement along the coast from Asia that did not reach Australia or remote Oceania. Other polymorphisms found in these populations may have been introduced by the movement of Austronesian-speaking and other more recent groups of people into the Pacific, because they share many polymorphisms with contemporary southeast Asians, Polynesians, and Micronesians that are not found in highlanders or Aboriginal Australians. There is evidence suggestive of later migration to Melanesia from Polynesia and Micronesia.     

Mitochondrial DNA variability of West New Guinea populations.

This paper reports human mitochondrial DNA variability in West New Guinea (the least known, western side of the island of New Guinea), not yet described from a molecular perspective. The study was carried out on 202 subjects from 12 ethnic groups, belonging to six different Papuan language families, representative of both mountain and coastal plain areas. Mitochondrial DNA hypervariable region 1 (HVS 1) and the presence of the 9-bp deletion (intergenic region COII-tRNA(Lys)) were investigated. HVS 1 sequencing identified 73 polymorphic sites defining 89 haplotypes; the 9-bp deletion, which is considered a marker of Austronesian migration in the Pacific, was found to be absent in the whole West New Guinea study sample. Statistical analysis applied to the resulting haplotypes reveal high heterogeneity and an intersecting distribution of genetic variability in these populations, despite their cultural and geographic diversity. The results of subsequent phylogenetic approaches subdivide mtDNA diversity in West New Guinea into three main clusters (groups I-III), defined by sets of polymorphisms which are also shared by some individuals from Papua New Guinea. Comparisons with worldwide HVS 1 sequences stored in the MitBASE database show the absence of these patterns outside Oceania and a few Indonesian subjects, who also lack the 9-bp deletion. This finding, which is consistent with the effects of genetic drift and prolonged isolation of West New Guinea populations, lead us to regard these patterns as New Guinea population markers, which may harbor the genetic memory of the earliest human migrations to the island.     

Reduced Y-chromosome,but not mitochondrial DNA,diversity in human populations from West New Guinea

To investigate the paternal population history of New Guinea, 183 individuals from 11 regional populations of West New Guinea (WNG) and 131 individuals from Papua New Guinea (PNG) were analyzed at 26 binary markers and seven short-tandem-repeat loci from the nonrecombining part of the human Y chromosome and were compared with 14 populations of eastern and southeastern Asia, Polynesia, and Australia. Y-chromosomal diversity was low in WNG compared with PNG and with most other populations from Asia/Oceania; a single haplogroup (M-M4) accounts for 75% of WNG Y chromosomes, and many WNG populations have just one Y haplogroup. Four Y-chromosomal lineages (haplogroups M-M4, C-M208, C-M38, and K-M230) account for 94% of WNG Y chromosomes and 78% of all Melanesian Y chromosomes and were identified to have most likely arisen in Melanesia. Haplogroup C-M208, which in WNG is restricted to the Dani and Lani, two linguistically closely related populations from the central and western highlands of WNG, was identified as the major Polynesian Y-chromosome lineage. A network analysis of associated Y-chromosomal short-tandem-repeat haplotypes suggests two distinct population expansions involving C-M208--one in New Guinea and one in Polynesia. The observed low levels of Y-chromosome diversity in WNG contrast with high levels of mtDNA diversity reported for the same populations. This most likely reflects extreme patrilocality and/or biased male reproductive success (polygyny). Our data further provide evidence for primarily female-mediated gene flow within the highlands of New Guinea but primarily male-mediated gene flow between highland and lowland/coastal regions.     

Blood groups of the people of Ahwaz, Iran

ABO, Rh and MN blood groups were studied among the people of Ahwaz, Khuzistan, Iran. The people of Ahwaz are characterized by high frequencies of the blood groups 0 (41.16%), Rh-positive (90.0%) and MN (48.13%). These frequencies are significantly different from those obtained in other Iranian populations, which is caused by the co-operation of various factors.
