Screen viewing, body mass index, cigarette smoking and sleep duration in Belgrade University student population: results of an observational, cross-sectional study.

Background: Subjects that spend more time working on computers or watching television could have a higher body mass index.

Aim: To assess the relationship between time spent in front of a screen and studying, body mass index (BMI), smoking, and sleep duration among university students.

Material And Methods: A cross-sectional study of 734 randomly selected students aged 21 ± 2 years (450 females) that responded an anonymous, structured questionnaire about time spent watching television or in front of a computer, time spent studying, number of daily hours of sleep, smoking habits and number of daily meals.

[Delta sleep-inducing peptide and its analogues alleviate the severity of metaphit-induced audiogenic seizures in rats].

Introduction: We investigated the potential of delta sleep-inducing peptide (DSIP) and its analogue DSIP-12 (a nonapeptide with alanine in position 2 of DISP molecule substituted by beta-alanine) and tetrapeptide analogue DSIP1-4, to antagonize metaphit(1-1 (3-isothiocyanatophenl)-cvyclohexyl piperidine) induced generalized reflex audiogenic seizures in adult male Wistar albino rats.

Material And Methods: Five groups of adult male Wistar rats were intraperitoneally treated with: (1) saline; (2) metaphit: (3) metaphit + DSIP, (4) metaphit + DSIPI-4 and (5) metaphit + DSIP-12. To examine the blocking effects of DSIP and its analogues on fully developed metaphit seizures, in the last three groups they were administered 8h after metaphit injection.
