Visual cognitive responses (P300) to moving stimuli were tested in 36 subjects with the aim to find the normal range of P300 parameters. Concomitantly, the circadian intra-individual variability of the P300 was studied in a subgroup of 6 subjects. Visual stimuli consisted of either coherent (frequent stimulus) or non-coherent motion (random stimulus). The oddball paradigm was applied for recording cognitive responses. P300 to rare stimuli had an average latency of 447.3±46.6 ms and amplitude of 12.9±6.0 mV. The average reaction time was in the range from 322 to 611 ms and there was no correlation between the reaction time and P300 latency. We did not find any significant circadian changes of the P300 parameters in the 6 subjects tested four times during the same day. Cognitive (event-related) responses (P300) displayed distinctly greater inter-individual variability (S.D. of 50 ms) when compared with pattern-reversal and motion-onset VEPs (S.D. of 6.0 ms and 14 ms, respectively). For this reason, the clinical use of P300 elicited by this kind of visual stimuli seems to be rather restricted and the evaluation of its intra-individual changes is preferable., Z. Kubová, J.

The relationship between vitamin D receptor (VDR) intragenic polymorphisms FokI, BsmI, ApaI and TaqI and bone mineral density (BMD) or biochemical markers of bone remodeling were investigated in 114 Czech postmenopausal women, on the average 62.5±8.9 years of age. Restriction fragment length polymorphisms in the VDR gene were assessed by PCR amplification and digestion with restriction enzymes FokI, BsmI, ApaI, and TaqI recognizing polymorphic sites in the VDR locus. Bone mineral density was measured at the lumbar spine and at the hip by dual-energy X-ray absorptiometry (DEXA, g/cm2). After adjusting for age and the body mass index (BMI), subjects with the ff genotype had 9.4 % lower BMD at the hip than those with the Ff genotype (p=0.0459, Tukey´s test). FF individuals had an intermediate BMD at the hip. A similar pattern of lower lumbar spine BMD was also found in ff individuals, but it did not reach statistical significance. There was no relationship between BsmI, ApaI and TaqI VDR polymorphisms and BMD at any skeletal site. Subjects with Aa (ApaI) genotypes had higher levels of propeptide of type I collagen (PICP) than homozygous AA (p=0.0459, Tukey´s test). In FokI, BsmI and TaqI restriction sites the biochemical markers of bone remodeling did not differ by genotype. In addition, no significant difference was observed in VDR genotypic distribution between osteoporotic women and non-osteoporotic controls in the study group. To conclude, the FokI genotype of the vitamin D receptor gene is related to bone mass at the hip in Czech postmenopausal women, whereas the importance of remaining VDR genotypes was not evident., K.

Studie shrnuje, porovnává a kriticky zhodnocuje koncepty, modely a teorie zabývající se vtahováním dětí do rodičovských konfliktů. Zabývá se modely, které vzešly z praxe systemických terapeutů, jako např. triangulace, perverzní koalice nebo aliance. Dále se věnuje konceptům, které vznikly v rámci studia rozvodových konfliktů jako je syndrom zavrženého rodiče a odcizený rodič. Cílem této studie je představit komplexní, jasný a ucelený popis, který by charakterizoval principy vtahování dětí do konfliktů jak v úplných, tak rozvedených rodinách., The review summarizes, compares, and critically evaluates theoretical constructs, which deal with the inclusion of children into the interparental conflict. The authors review constructs based on the work of systemic therapist, such as triangulation, alliance, perverse coalition, and alliance, and psychosomatization. Either, they review theories based on studies of divorced families, such as parental alienation syndrome, and parental alienation. The goal of this study is to introduce enough complex, clear, and comprehensive description, which embrace the principles of inclusion of children into interparental conflicts, both in non-divorced and divorced families., Olga Trampotová, Lenka Lacinová., and Obsahuje seznam literatury
The article outlines the book culture of the Rudolphine period on the examples of several works by Tycho Brahe (Instruments of the Renewed Astronomy), Johannes Kepler (Somnium: The Dream, or Posthumous Work on Lunar Astronomy; Conversation with the Starry Messenger) and Galileo Galilei (The Starry Messenger). It is based on both research outcomes that have already been published and those that are being prepared for printing. and Alena Hadravová.
Studie Klause Dögeho obsahuje analytické poznámky ke kompozici hudebního skladatele Bohuslava Martinů, věnovanému památce vyhlazení Lidic., In his Memorial to Lidice (composed in the summer of 1943) Martinů pays tribute to the complete extinction of the Czech village Lidice and its inhabitants by the Nazis. In the composition he uses – as he has never done before in this way – many traditional idioms and quotation-like elements in order to express all the sadness, fright and pain of his subject., Klaus Döge., Rubrika: Studie, and Německé resumé na s. 18, anglický abstrakt 5.
Objectives. The main goal of the study was to analyse in detail specific family indicators and their relation to selected indicator of life satisfaction in a representative sample of Czech children. Sample and setting. A total number of 4 351 children aged 11, 13 and 15 years out of 88 randomly selected schools in Czech Republic formed the study population. The data was acquired in the framework of the WHO study “The Health Behaviour in School-aged Children: A WHO Cross National Study” (HBSC) in June 2010 by means of standardized questionnaires. Research questions. Is formal structure of family or the quality of communication more important for children's life satisfaction? Statistical analysis. Statistical analysis included descriptive analyses, the x2 test of independence in contingency tables, Fisher’s exact test, two samples T-test, one and two way analysis of variance using the NCSS 2007 program. Logistic regression analysis was performed to evaluate the influence of family on life satisfaction of children and prevalence odds ratios with 95% confidence interval were calculated as measure of association. Results. Life satisfaction was high for majority of children, it reached two thirds of possible maximum at both of the followed scales (Cantril index, Huebner scale) for the whole sample. Life satisfaction was significantly associated (p<0,001) with age, gender, formal structure of family and quality of communication in family. Children from complete families with easy or very easy communication with both parents had the highest values at both of the followed life satisfaction scales. Study limitations. Limitations of the study result from the cross-sectional design and data based on self-reports. Both life satisfaction and family were analysed on the basis of selected question categories., L.
