A new extraction technique based on the off-line combination of pressurized-liquid with solid-phase extraction (PLE-SPE) is described. The method was used for the extraction of bioactive phenolic acids (protocatechuic, p-hydroxybenzoic, 2,3-dihydroxybenzoic, chlorogenic, vanillic, caffeic, p-coumaric, salicylic acid), cinnamic acid and hydroxybenzaldehydes(More)
The need to overcome gender differences in physical activity (PA) is an essential part of health and education policy. Adolescent girls display less PA than boys. The aim of the presented research was to determine whether 4-week monitoring with pedometers can influence differences between the level of PA amongst adolescent girls and boys. Four-week(More)
The plant hormones cytokinins (CKs) regulate multiple developmental and physiological processes in Arabidopsis (Arabidopsis thaliana). Responses to CKs vary in different organs and tissues (e.g. the response to CKs has been shown to be opposite in shoot and root samples). However, the tissue-specific targets of CKs and the mechanisms underlying such(More)
Long-term day-to-day monitoring of physical activity (PA) has not been undertaken in adolescents despite PA declines rapidly during adolescence. This study monitored the school year-round pedometer-determined PA of pupils attending high school in the Czech Republic. We assessed their PA levels; appraised the school year-round variability of their PA; and,(More)
This study assessed the physical activity (PA) levels and its variability across days, months and seasons of two groups of high school pupils: those who did and those who did not participate in regular organized after-school physical activity (ASPA). Thirteen pupils wore pedometers continuously for one school-year, logged their step counts into record(More)
The pedometer is a widely used research tool for measuring the level and extent of physical activity (PA) within population subgroups. The sample used in this study was drawn from a population of university students to examine the influence of the monitoring interval and alternate starting days on step-count activity patterns. The study was part of a(More)
OBJECTIVE Good parent-child communication is associated with adolescent well-being. The aim of the present study was to report time trends in parent-adolescent communication in biological and stepfamilies in the Czech Republic between 2002 and 2014 and to assess gender and age differences. METHODS The research sample consisted of 16,160 adolescents aged(More)
Transjugular intrahepatic portosystemic shunt (TIPS) is a side-to-side portocaval shunt for threatening complications of portal hypertension. The purpose of this study was to evaluate in first 33 patients indicated for TIPS insertion in our institution the efficacy, complications, and mortality. Indication was failure of sclerotherapy or ligation in control(More)
BACKGROUND A multilevel theoretical framework of physical activity (PA) promotion that addresses supportive environments, PA behavior, community action, and PA promoting policies is related to research and development in an international comparative study. METHODS Most-different and most-similar case selection was applied to data from 8 European Union(More)
OBJECTIVE School is a place where students spend most of their daytime hours. Previous studies indicate that the class climate significantly affects students in both positive and negative ways. The aim of our study is to describe the trends in the psychosocial school environment based on four surveyed years in the Czech Republic. METHODS The trends in(More)
