Distribution of Herbivorous Fish Is Frozen by Low Temperature.
2016
AbstractThe number of herbivores in populations of ectothermic vertebrates decreases with increasing latitude. At higher latitudes, fish consuming plant matter are exclusively omnivorous. We assess whether omnivorous fish readily shift to herbivory or whether animal prey is typically preferred. We address temperature as the key factor causing their absence at higher latitudes and discuss the potential poleward dispersion caused by climate changes. A controlled experiment illustrates that rudd (Scardinius erythrophthalmus) readily utilize plant matter at water temperatures above 20 °C and avoid its consumption below 20 °C. Field data support these results, showing that plant matter dominates…
Macrophytes shape trophic niche variation among generalist fishes.
2017
Generalist species commonly have a fundamental role in ecosystems as they can integrate spatially distinct habitats and food-web compartments, as well as control the composition, abundance and behavior of organisms at different trophic levels. Generalist populations typically consist of specialized individuals, but the potential for and hence degree of individual niche variation can be largely determined by habitat complexity. We compared individual niche variation within three generalist fishes between two comparable lakes in the Czech Republic differing in macrophyte cover, i.e. macrophyte-rich Milada and macrophyte-poor Most. We tested the hypothesis that large individual niche variation…
Immunogenicity and Safety of Primary and Booster Vaccinations of a Fully Liquid DTaP-IPV-HB-PRP-T Hexavalent Vaccine in Healthy Infants and Toddlers …
2018
To support a fully liquid, diphtheria (D)-tetanus (T)-acellular pertussis (aP)-inactivated poliovirus (IPV)-hepatitis B (HB)-Haemophilus influenzae b (PRP-T) vaccine in Europe using a 2, 3, 4 month primary series and a booster at 11-15 months of age. Phase III, randomized, observer-blind studies in Germany and the Czech Republic. Participants who had not received HB vaccine were randomized to a 2, 3, 4 month primary series of DTaP-IPV-HB-PRP-T (group 1; N = 266) or a reconstituted DTaP-HB-IPV//PRP-T comparator (group 2; N = 263) and a booster of the same vaccine. Pneumococcal vaccine (PCV13) and rotavirus vaccine were coadministered at 2, 3, 4 months, and the booster was coadministered with…
Once-daily tiotropium Respimat® 5 μg is an efficacious 24-h bronchodilator in adults with symptomatic asthma
2015
SummaryIntroductionOnce-daily tiotropium Respimat® 5 μg is an efficacious add-on therapy to inhaled corticosteroids (ICS) with or without long-acting β2-agonists in patients with symptomatic asthma. The objective of this study was to investigate whether the dosing regimen of tiotropium (once- versus twice-daily), delivered via the Respimat® SoftMist™ inhaler, affected 24-h bronchodilator efficacy and safety versus placebo Respimat® in patients with asthma who were symptomatic despite medium-dose ICS therapy.MethodsA randomised, double-blind, placebo-controlled, crossover study with 4-week treatment periods of tiotropium 5 μg (once-daily, evening) and 2.5 μg (twice-daily, morning and evening…
Prevalence of antibodies to human papillomaviruses in the general population of the Czech Republic.
1998
Sera from 450 individuals between the age of 1 and 80 years, representing the general population of the Czech Republic, were tested for the presence of antibodies to human-papillomavirus(HPV)-derived antigens. The following antigens were used: (i) HPV1 virions; (ii) HPV16, -18 and -33-virus-like particles (VLP); (iii) peptides derived from L2 open reading frames (ORFs) of HPV16 and HPV6/11; (iv) peptides derived from HPV16 E2, E4 and E7 ORFs of HPV16. The prevalence of antibodies reactive with the capsid-derived antigens was age-dependent, while no clear age dependence was observed in the distribution of antibodies to peptides derived from HPV16 early proteins. In individual sera, high corr…
Bibliometric analysis of European publications between 2001 and 2016 on concentrations of selected elements in mushrooms.
2020
This article presents a bibliometric study of 200 European publications released between 2001 and 2016, about the contamination of mushrooms by selected elements. The analysis includes figures on the type of analyte, its concentration, the species of fungi, and its country of origin. In the literature review, 492 species of mushrooms (wild-growing and cultured) found in 26 European countries and their concentration of 74 associated elements were analysed. The papers, which dealt mainly with the heavy metal (Cd, Cu, Fe, Pb, and Zn) concentrations of mushrooms, primarily came from Turkey, Poland, Spain, and the Czech Republic. More than 50% of the publications provided data about edible mushr…
The rs1527483, but not rs3212018, CD36 polymorphism associates with linoleic acid detection and obesity in Czech young adults
2018
AbstractRecent evidence has raised the possibility of the existence of a sixth taste modality – that is, taste for fat – which is mediated by lingual CD36 and plays a role in obesity. Consequently, the genetic polymorphism of CD36 has been shown to be associated with altered oro-sensory detection of dietary lipids. In the present study, we investigated the relationship between oro-sensory perception of linoleic acid (LA), two CD36 polymorphisms (rs1527483 and rs3212018), obesity parameters and craving habits for dietary lipids in young Czech adults. We also sequenced 5 and 6 exons of CD36 to trace out any new mutation that might be responsible for the difference in taste perception. We obse…
The Impact of Environmental Conditions on Efficiency of Host Plant DNA Barcoding for Polyphagous Beetles.
2015
Recently, several papers were published dealing with host plant identification for selected species of insects, including beetles. These studies took advantage of the DNA barcoding approach and generally showed that it is possible to identify diet composition from plant DNA present in insect guts. However, none of these studies considered how the impact of environmental conditions affected the likelihood of insect feeding and, therefore, the presence of host plant DNA that could be amplified and sequenced. In the present study, individuals of the polyphagous weevil Centricnemus leucogrammus (Germar, 1824) (Curculionidae: Entiminae) were used to test the hypothesis that harsh environmental c…
The influence of the Covid-19 pandemic on Czech-Polish cross-border cooperation: From debordering to re-bordering?
2021
Abstract The COVID-19 pandemic brought many changes to social behaviours in Europe. One of its major consequences was the temporary closure of borders, which was introduced as a measure to prevent the uncontrolled pandemic spreading and involved internal Schengen borders. This has had a major impact in the way in which cross-border cooperation has been conducted in Europe, including the Czech-Polish borderland, as it dramatically restrained all flows across borders. In this paper, we evaluate the impact of the pandemic on five roles of cross-border cooperation: 1) as a multi-level governance form; 2) as a regional development tool; 3) as a para-diplomacy form; 4) as a post-conflict reconcil…
Trends in Medically Attended Injuries in Czech Adolescents.
2017
Objective: Due to the importance of surveillance of injuries and accidents in the Czech Republic, the purpose. of this study was to report the temporal trends of injuries of Czech adolescents between 2002 and 2014. Methods: Adolescents (N = 20,038) from the Czech Republic, that took part in the 2002, 2006, 2010 and 2014 HBSC study, reported the frequency of medically attended injuries in the past 12 months. Repeated binary logistic regressions with different years as reference categories were performed. Results: Less than half (44.7%) of all Czech adolescents reported they had experienced at least one medically attended injuries in the past 12 months, with boys experiencing more injuries th…
