We studied the effect of isolated and combined exposure to 24-h illumination and industrial frequency magnetic field on the expression of intracellular molecular apoptosis regulator Bcl-2 in the liver. Previous experiments showed enhanced expression of Bcl-2 protein in liver cells in animals maintained under conditions of 24-h illumination, whereas exposure to industrial frequency magnetic field had practically no effect on this process. Under conditions of combined exposure to 24-h illumination and industrial frequency magnetic field, magnetic field partially suppressed the expression of Bcl-2 induced by 24-h illumination.

The study of circadian rhythms has been critically dependent upon analysing mouse home cage activity, typically employing wheel running activity under different lighting conditions. Here we assess a novel method, the Digital Ventilated Cage (DVC, Tecniplast SpA, Italy), for circadian phenotyping. Based upon capacitive sensors mounted under black individually ventilated cages with inbuilt LED lighting, each cage becomes an independent light-controlled chamber.

Introduction: The relationship between 24-h movement behaviours (i.e. sleep, sedentary behaviour and physical activity) and adiposity in preschoolers remains unclear.

Direct thrombin inhibitors (designated as EuRL-DTIs) were partially purified from ethanol extracts of Euphorbia resinifera O.Berg latex. The obtained EuRL-DTIs comprised four major compounds: two isomers of phenolic compounds (CHO) and two amide compounds (tentatively identified as CHNO and CHNO), as identified by liquid chromatography and electrospray ionisation quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS), attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, and/or nuclear magnetic resonance (NMR) spectroscopy.

Circadian rhythms, intrinsic 24-h cycles that drive rhythmic changes in behavior and physiology, are important for normal physiology and health. Previous work in adults has identified sex differences in circadian rhythms of melatonin, temperature, and the intrinsic period of the human circadian timing system. However, less is known about sex differences in circadian rhythms at other developmental stages.

This research aimed to assess the shear bond strength (SBS) of metal brackets bonded to composite veneers using different surface preparations. One-hundred composite disks were divided into 10 different groups whereby each group combines a surface preparation (roughening or no roughening), etching agent (37% phosphoric or 9.5% hydrofluoric acid), adhesive protocol (self-etch or total-etch), and bonding agent (with or without G-Premio Bond).
