[Medical genetic study of the population of Turkmenia. VI. An analysis of the genetic component of fertility dispersion in the population of Nokhor].

The index of the total opportunity for selection (the Crow index) and the genetic part of total variance in progeny size was studied in small Turkmenian isolated population "Nochur". The average number of children per family in families that had completed their reproductive period was 6.84, the variance being 12.31. The index of total opportunity for selection was computed by the standard method of J. Crow: Jm = 0.313, Jf = 0.454, Jtot = 0.909. Some correlation coefficients of the progeny size were calculated. The sister-sister correlation coefficient was significantly distinguished from 0 and was equal to +0.22. Thus, the genetic part of total variance of the progeny size is 0.4-0.5. It is essential for understanding of the Jf estimation.

[Polymorphism of human erythrocyte carbonic anhydrase in the population of Moscow and in the native populations of Siberia detected by polyacrylamide gel electrophoresis].

Carbonic anhydrase of human erythrocytes was separated by polyacrylamide electrophoresis into four fractions determined, obviously, by two loci, CAI and CAII. Investigation of Moscow population sample of 458 men (516 healthy and 42 with schizophrenia) showed monomorphism of carbonic anhydrase for these two loci. Carbonic anhydrase I and carbonic anhydrase II were differentiated with fluorogenic substrates. The polymorphic variant of CAII was discovered while studying the sample of Siberian mongoloids (Evenks and Jakuts) with frequency 0,047 and 0,045, respectively.

Robust estimation of population size in closed animal populations from capture-recapture experiments.

In this paper the problem of finding robust estimators of population size in closed K-sample capture-recapture experiments is considered. Particular attention is paid to models where heterogeneity of capture probabilities is allowed. First, a general estimation procedure is given which does not depend on any assumptions about the form of the distribution of capture probabilities. This is followed by a detailed discussion of the usefulness of the generalized jackknife technique to reduce bias. Numerical comparisons of the bias and variance of various estimators are given. Finally, a general discussion is given with several recommendations on estimators to be used in practice.

[Genetic composition of the Chilean population: the population from San Pedro de Atacama].

This work describes the genetic composition of atacameños from San Pedro de Atacama. The results show that a) the contribution of non-indigenous genes is relatively low, in relation to the spanish immigration period. b) the Hardy-Weinberg genetic disequilibrium for MNSs system should have biological implications c) the variant for esterasa D enzyme may be the same found in other chilean populations.

[The consumption of food of animal origin distinct from milk: meat, fish, eggs in the school-age population of the community of Madrid. The Food Consumption and Nutritional Status of the School-Age Population of the Autonomous Community of Madrid Group].

The aim of this study was to assess the intake of foods of animal origin other than milk, as well as their role in the diet of children, in a representative sample of a school-aged population from the Community of Madrid (CAENPE study). A 4 day assessment of the dietary intake was conducted by applying a combination of the methods of 24-hour recall and a written record of the estimated consumption. We studied 2,608 schoolchildren between the ages of 6 and 14 years. The subjects were divided into groups according to age and sex. We found that the average meat intake was 213 +/- 87 g/person/day. The consumption of meat was significantly higher in boys (p < 0.05) and increased with age both in boys (p < 0.001) and girls (p < 0.05). Meat provided 40% of the saturated fat, 34% of the cholesterol and 33.5% of the protein in the diet. Fish intake was 77 +/- 64 g/person/day, with higher consumption in boys (p < 0.05) and with no influence of age. Fish supplied 11% of the dietary protein and only 1.2% of the saturated fat. Egg consumption was 31 +/- 20 g/day/person, which represents 3 eggs per week. The consumption of eggs was also higher in boys than in girls (p < 0.05) and provides 28% of the dietary cholesterol. We conclude that meat provides more than one third of the dietary protein and alone covers the RDA for protein. In addition, meat also contributes the highest amount of dietary saturated fat and cholesterol. Egg and fish intake is adequate; hence, it would be desirable to reduce the excessive meat intake in order to equilibrate the macronutrients and cholesterol supplied by the diet.

Population review: (5). The population aged 60 and over.

The elderly population of the UK is currently growing more slowly than in the past, but is becoming older. When the larger post-Second World War birth cohorts reach their sixties this trend will be reversed. In comparison with their predecessors, more of today's elderly have spouses and children. The proportions of divorced people among the elderly, while growing rapidly, are still small. Changes in living arrangements have been substantial. Co-residence between generations has continued to become less, and living alone more common. The number of elderly people with children close at hand has fallen and the proportion of very old people living in institutions has increased. Elderly people are far less likely to be in paid work than in the past, but provide a great deal of the informal care needed by disabled parents and other people aged 65 or over. Mortality rates at older ages have fallen, but the extent of self-reported limiting long-term illness has risen. This may reflect increased awareness of health problems among elderly people. More positively, there are signs that the extent of serious disability has fallen.

[Participation of the population in mass screening and the role of complete population surveillance for detection of the disease studied (from the experience of the methodical measures for the prevention of ischemic heart disease in Kaunas)].

A comparison of the results of examination of 100 individuals, some of whom had taken part in the survey while the others had refused it and information about them was specially obtained by other means (in some cases by collecting the medical documentation), is presented. Factors conducive to the development of ischemic heart disease predominated among individuals who refused to take part in the survey. The incidence of ischemic heart disease and arterial hypertension was also higher among them. It is concluded that individuals who refuse examination during preventive survey form a group with a high risk of the development of ischemic heart disease; this group should be taken into account when therapeutic and preventive measures are conducted among the population.
