One click away: Pilot study of the perceived academic impact of screen time among pharmacy students.

Introduction: We examined the perceived impact (direct and indirect) of screen time on pharmacy students' academics and how pharmacy students attempt to overcome perceived negative impacts.

Methods: Focus group interviews with first-year and third-year pharmacy students at a single school of pharmacy were conducted, digitally audio-recorded, transcribed, and analyzed. Screen time was defined as time on any device with internet access, and academic impact was referred to as studying and academic performance.

A randomized trial of the efficacy of hand disinfection for prevention of rhinovirus infection.

Background: Hand disinfection is frequently recommended for prevention of rhinovirus (RV) infection and RV-associated common colds. The effectiveness of this intervention has not been established in a natural setting. The purpose of this study was to determine the effect of hand disinfection on RV infection and RV-associated common cold illness in a natural setting.

Yield of human adipose-derived adult stem cells from liposuction aspirates.

Background: Primary cultures of isolated human adipose-derived adult stem (ADAS) cells are multipotent and differentiate in vitro along the adipocyte, chondrocyte, neuronal, osteoblast, and skeletal muscle pathways.

Methods: We examined the ADAS cell yield per unit volume of liposuction tissue, and their surface protein phenotype by flow cytometry. Adipogenesis was assessed by Oil Red O staining and ELISA analysis of leptin secretion.

Estimation of available energy of dietary fibres by indirect calorimetry in rats.

Background: Knowledge of energetic availability of dietary fibres is important for human nutrition. But up to now results are often different and depend on the methods used. Estimation of metabolisable energy of dietary fibres (mainly by balance technique) is a time-consuming procedure and needs special technical effort.

Energy expenditure and substrate oxidation rates of obese rats during a 12-day treatment with dexfenfluramine.

Serotoninergic neuronal networks are included in regulation and modification of eating behavior and energy metabolism. Dexfenfluramine (dF), a serotonin releaser and reuptake inhibitor, was used to investigate changes in food intake, body weight development, energy expenditure, respiratory quotient, and substrate oxidation rates for 12 days. Rats which had been made obese by postnatal overfeeding received an energy-controlled mash diet and water ad libitum and were intraperitoneally injected with either saline or 5 or 10 mg dF/kg.
