Nowadays, a great attention is paid to the biological activity of plant polyphenols and their potential importance for the human health. Therefore knowledge regarding the dietary intake of polyphenols and their particular subclasses has gained interest. In this report, the results of a pilot study evaluating the average polyphenol content in the Czech diet have been presented.

Objective: The marine n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) exert numerous beneficial effects on health, but their potency to defend against development of peripheral insulin resistance of healthy person with overweight remains poorly characterized. We aimed to evaluate the effect of a combination intervention using EPA + DHA and the lifestyle modification (LSM) in women with overweight.Method: In a parallel-group, three-arm, randomized trial (UMIN Clinical Trials Registry - R000031131), 34 women were assigned to a 12-week-intervention using corn oil (1.5 g/day; placebo); LSM and corn oil (1.5 g/day; LSM); or LSM and EPA + DHA concentrate (1.5 g/day, containing ~ 0.6 g EPA + DHA; LSM & n-3). At baseline and after intervention, anthropometric measurements including bioelectrical impedance analysis, spiroergometry, 24-hours dietary recall, and various metabolic markers, adiponectin and cytokines were evaluated in serum using standard procedures. Data from 29 women were used for the final evaluation. Wilcoxon two-sided rank-sum test was used to inspect the differences between LSM and LSM & n-3, and placebo groups, with a p-value of ≤ 0.05. All computations were performed with MATLAB Statistics Toolbox.Results: In comparison with placebo, LSM and LSM & n-3 decreased body weight, waist circumference, and body fat, and increased VO2max/kg. LSM & n-3 increased adiponectin levels in comparison to LSM. Fasting insulin, IL8, and cholesterol were decreased by LSM, but were unchanged by LSM & n-3. IL6 was not affected in LSM & n-3, while it was increased in LSM. Other inflammatory markers, as well as leptin, LIF, follistatin, BDNF, and fasting triacylglycerol were not significantly affected by any of the interventions.Conclusion: Besides preventing a modest negative effect of LSM on IL6 and adiponectin level, the combination of LSM and EPA + DHA supplementation could be probably used to improve the functional capacity of adipose tissue in women with overweight.

The paper discusses selected aspects of media education in relation to issues currently discussed in the Czech media. It outlines how these aspects are treated in one introductory seminar when teaching three different types of students - secondary school students, university students and University of the Third Age (U3A) students. It shows that students are introduced to the concept of media in a similar way, even though the specific topics discussed in the following seminars are different. The paper stresses the need to focus on critical analysis of media communications using essential questions asking about the ownership of the media, information processing and transmission, the phenomenon of representation, and the audience.

Background. Fish pond management can substantially modify the hydrological regime and ecological quality of receiving waters (usually rivers, canals, and ponds downstream in an interconnected system) with potentially positive or negative impacts on watershed functioning. To evaluate these effects with respect to carp pond management, the environmental impacts of semi-intensive farming on discharged water quality were monitored at four differently managed carp ponds, differing in trophic status (two eutrophic and two hypertrophic ponds). Materials and methods. Fundamental determinants of pond inflow and outflow water quality were monitored monthly from April to October 2009. Water temperature, pH, and dissolved oxygen concentration and saturation were measured in situ whilst hydrochemical and microbiological parameters were assessed in the laboratory. Results. Compared to the inflow water, in the effluents there was a significant decline in numbers of bacterial loading indicators (Escherichia coli, enterococci, faecal coliform and mesophilic bacteria) in the outflow water. In ponds with the poor quality inflow water (downstream of water treatment plant discharges), a significant decrease was also registered in nutrients (N-NH4, N-NO3, total nitrogen, P-PO4, and total phosphorus) and organic loads? (five-day biological oxygen demand, chemical oxygen demand) of pond effluents. At the pond supplied with good quality river water, however, the same determinants showed that effluent water quality worsened significantly. Total organic carbon and suspended solids increased in effluents of ponds with high fish biomass stocked. Conclusion. The results demonstrate that, during the growing season, properly managed carp ponds represent ecosystems with high self-cleaning ability. They may play an important role in the nutrient balance, storage and trapping in agricultural landscape with high population density. [ABSTRACT FROM AUTHOR]

We found a male Hyalomma rufipes Koch, 1844 tick feeding on a horse grazing near Valtice, south Moravia, Czech Republic on October 24, 2019. The horse was born in Czechland and did not leave the country at least during the last five years. Relevant findings of Hyalomma ticks in other parts of central Europe are reviewed, including also records of pre-imaginal Hyalomma marginatum complex ticks on migrating birds all over Europe.

Aim: Obesity and physical inactivity had already reached epidemic, becoming one of the leading causes of death and disability worldwide. The objective of this study was to investigate the current level and a nearly three decades' trend of muscular fitness (MF) and the nutritional state of Czech children.Methods: In 2013, cross-sectional epidemiological survey was conducted in schoolchildren with examination of the anthropometric characteristics and measured MF using a UNIFIT test, which normative for MF categories was given as results of national monitoring data collected in 1987. In total 896 current schoolchildren (472 aged 8-9 years and 424 aged 12-13 years) were examined from selected children through stratified sampling from the Czech Republic.Results: Against 31% of children from 1986 there were 74% of current children classified as "poor" or "below normal" in the MF category (p<0.001). MF was inversely associated with BMI. Poor posture was diagnosed in 24% of children, more frequently in overweight (OW) and obese (OB) children in comparison to normal body weight children (p<0.001). In comparison to 10% of OW and OB children in 1991, using these cut-off points for body mass index references, the current prevalence of OW and OB doubled (19.8%).Conclusions: Current Czech schoolchildren showed a doubled prevalence of OW and OB during the last two decades and simultaneously during nearly three decades there were more than doubled prevalence of "poor" or "under normal" MF of children, with overall dramatic decrease of MF in current schoolchildren.
