The primary aim was to determine frequencies of mutations related to risk of venous thrombosis in healthy Caucasians in Central Bohemia. In a cohort of 1527 healthy individuals the frequency of risk alleles for the mutations FV Leiden and FII 20210G>A was 4.5 % and 1.3 %, respectively. Frequency of 4G PAI-1 allele was 55.5 %. Genotype frequencies were: GG 91.03 %, GA 8.91 %, an d AA 0.07 % for FV Leiden; GG 97.45 %, GA 2.49 %, and AA 0.07 % for FII 20210G>A; 4G/4G 30.26 %, 4G/5G 50.56 %, and 5G/5G 19.19 % for PAI-1. Frequency of the risk allele A in polymorphism SERPINC1 (IVS +141G >A) was 11.3 %, and frequencies of genotypes were as follows: GG 78.36 %, GA 20.66 %, and AA 0.98 %. Frequency of the risk allele T for polymorphism GP6 13254T>C was 87.7 %, and frequencies of genotypes were as follows: TT 77.14 %, TC 21.15 %, and CC 1.70 %. Frequency of the risk allele A in polymorphism CYP4V2 (Lys259Gln ) was 65.2 %, and frequencies of genotypes were: CC 12.25 %, CA 45.12 %, and AA 42.63 %. All observed genotypes and alleles frequencies were without gender differences. Their occurrences confirm a relatively high prevalence of hereditary thrombophilia predisposition in the Czech Republic., T. Kvasnička ... [et al.]., and Obsahuje bibliografii a bibliografické odkazy
A mineralogical study of the weathering crusts rich in P and Mn from the locality Hodušín - Božetice at Milevsko is presented. The locality belongs to the central part of the variegated group of Sušice and Votice in the Moldanubian Unit. From the analytical methods used, the IR-spectroscopy yielded satisfactory results. The main crust components subjected to weathering are apatite (of a CarHap B - dahllite type) and Mn-minerals (massive black psilomelane, the needle-aggregates probably comprise a poorly recrystallized psilomelane). Disintegrated rocks consist of a mixture of clay minerals, calcite and relicts of primary minerals (quartz, K-feldspars, albite, pyroxene and rutile). The origin and the source material of these crusts rich in P and Mn can not be unambiguously determined. Apatites without CL-effects indicate that the weathering crusts have originated in a strongly oxidative environment. Well documented neighbouring occurrences of phosphate minerals in the variegated group of Sušice and Votice are associated with graphitic rocks. Optical and quantitative chemical analyses of the rocks suggest that the source of apatite could possible be calc-silicate rocks (erlans) close to the graphitic rocks. Hypothetically, the metaphosphorite layers in the variegated Moldanubian Unit can also be considered a possible source of phosphorus., M. Brož, M. Kovářová, Z. Losos, M. Linhartová and V.

Od počátku 90. let 20. století dochází k poměrně velkým změnám v reprodukčním chování obyvatel České republiky, mimo jiné výrazně narůstá podíl dětí narozených mimo manželství. Článek podrobně popisuje vývoj intenzity plodnosti nevdaných žen ve srovnání s ženami vdanými v letech 1989-2014 na základě dat běžné evidence. Pozornost je věnována třem hlavním vlivům působícím na podíl dětí narozených mimo manželství, nejvíce pochopitelně intenzitě mimomanželské a manželské plodnosti (podle věku a pořadí narozených dětí). Analýza ukazuje, že přestože dochází od počátku 21. století ke sbližování intenzity plodnosti vdaných a nevdaných žen, prokreační chování těchto žen se stále výrazně odlišuje (průměrný věk matky při narození (prvního) dítěte, struktura narozených dětí podle pořadí narození)., Since the beginning of the 1990´s there have been relatively large changes in the reproductive behaviour of the population of the Czech Republic, including a significant increase in the proportion of children born out of wedlock. The paper describes the development of fertility rates among unmarried and married women in the years 1989-2014 in detail. Attention is paid to three main influences which are responsible for the proportion of children born out of wedlock, and obviously above all to the rates of nonmarital and marital fertility (by age and by birth order). The analysis shows that although there has been a convergence of the rates of fertility of married and unmarried women since the beginning of the 21st century, the reproductive behaviour of these women is still significantly different (average age of mother at birth of (first) child, distribution of birth order)., Barbora Kuprová., and Obsahuje bibliografii
