The aim of this study was to develop and evaluate a new test for the soccer goalkeeper that involved perceptual and movement response components (i.e., sprint running, jumping, diving, and direction changing). The evaluation consisted of measurements in different age (U19 [18.0 ± 0.9 years], n = 21; U14 [14.1 ± 0.3 years], n = 13) and performance (i.e., first goalkeepers and substitutes) groups...

Balance is hypothesized to be important in alpine skiing, while it is known that balance depends on anthropometric indices. The aim of this investigation was to explore the association between balance, anthropometrics and skiing-results over two competitive seasons among youth alpine-skiers. Eighty-one skiers (40 females) participated in this study. The participants were tested twice over two c...

We point out a symmetry exhibited by pairs of entangled states and discuss its possible applications in quantum information. More specifically, we consider quadripartite systems prepared in bipartite product states of the form #!$= #"$12 ! #"$34 and let the uncorrelated subsystems 14 and 23 interact by a given unitary U14 ! U23 describing two bilinear interactions: we show that entanglement bet...

The aim of this study was to identify the relative age effect (RAE) in young Polish male (n = 3849) and female (n = 3419) basketball players aged 14 to 22 years competing in the elite games of the Polish Youth Championships. The distribution of birth dates, body height, players' match statistics, and the results of teams participating in championships were identified. The RAE was observed in ma...

The aim of this study was to quantify the motion demands of match-play in elite U12 to U16 age-group soccer players. Altogether, 112 players from two professional soccer clubs at five age-group levels (U12-U16) were monitored during competitive matches (n = 14) using a 5 Hz non-differential global positioning system (NdGPS). Velocity thresholds were normalized for each age-group using the mean ...

The aim of this study was to evaluate the antitumour activities and genotoxic effects of isoliquiritigenin (ISL) combined with cyclophosphamide (CP) in vitro and in vivo. U14 cells were treated with either of ISL (5-25 μg/mL) or CP (0.25-1.25 mg/mL) alone or with combination of ISL (5-25 μg/mL) and CP (1.0 mg/mL) for 48 h. The proliferation inhibitory effect in vitro was evaluated by MTT and co...

This study aimed to assess the anthropometric characteristics, nutrient intake levels, nutritional status of elite adolescent soccer players, and dietary quality athletes. Elite male players youth team a club in Turkish Super League were included this by categorizing them into three separate groups as U14/U15 (n=32), U16/U17 (n=44), U19 (n=17). Anthropometric measurements athletes food consumpt...

The buccal mucosa is the site with the highest risk of contracting a malignancy in habitual betel quid chewers who expose the buccal mucosa to high doses of carcinogens. Of all oral cancers, those of the buccal mucosa are associated with the poorest prognoses. Therefore, it would be helpful to have an animal model to evaluate new treatment modalities for buccal mucosa cancer. In the present stu...

We have analyzed the organization of pre-rRNA processing by confocal microscopy in pea root cell nucleoli using a variety of probes for fluorescence in situ hybridization and immunofluorescence. Our results show that transcript processing within the nucleolus is spatially highly organized. Probes to the 5' external transcribed spacer (ETS) and first internal transcribed spacer (ITS1) showed tha...
