The effect of sleep on the psychological functions of adolescents

The quality of sleep is one of the main factors for the homeostasis of the body, the functioning of the brain and therefore the psychological functions of the individual. Sleep undergoes various changes during life. Significant sleep changes can be observed in adolescents. During this developmental period, there is a shift in circadian preferences towards a later chronotype, which is often in conflict with the demands of functioning in everyday life (for example waking up to school). Because of that this group is highly vulnerable to chronic sleep restriction and associated sleep deprivation, which can lead to many pathologies. The aim of this study was to investigate the effect of partial sleep deprivation on cognitive function and emotional regulation in adolescents. The study involved 59 adolescents aged 14 to 21 years, 30 of them were exposed to partial sleep deprivation (4 hours/night) and 29 of them slept normally (8 ± 1 hours/night). The day after instructed sleep/sleep deprivation, participants completed an experimental battery of cognitive tests. The study found that adolescents after one night of partial sleep deprivation showed greater levels of subjective sleepiness than their peers after a night of normal sleep. This effect of sleep deprivation was stronger in girls than in boys. Also...

Interakce proteinů \kur{Methoprene tolerant a Taiman} - Příprava konstruktů pro expresi v S2 buňkách
 KITZBERGER, František
The aim of this thesis was to create a set of construct consisted of actin or Hsp70 promoter and complete coding DNA sequence (CDS) of Met (Methoprene tolerant) or tai (taiman) genes from lindenbug (Pyrrhocoris apterus) tagged by green fluorescent protein, or red fluorescent protein. These constructs will be used to study interaction of these proteins in vivo (Schneider S2 cell line) in the future.
