The circadian body temperature rhythm of Djungarian Hamsters (Phodopus sungorus) revealing different circadian phenotypes

Abstract: Djungarian hamsters (Phodopus sungorus) of our breeding stock show three rhythmic phenotypes: wild type (WT) animals which start their activity shortly after “lights-off” and are active until “lights-on”; delayed activity onset (DAO) hamsters whose activity onset is delayed after “lights-off” but activity offset coincides with “lights-on”; and arrhythmic hamsters (AR) that are episodically active […]

Predicting energy expenditure of physical activity using hip- and wrist-worn accelerometers

Abstract To investigate the association between physical activity and health, we need accurate and detailed free-living physical activity measurements. The determination of energy expenditure of activity (EEACT) may also be useful in the treatment and maintenance of nutritional diseases such as diabetes mellitus. Minute-to-minute energy expenditure during a 24-h period was measured in 60 sedentary […]

Chemotherapy-induced cognitive impairment is associated with decreases in cell proliferation and histone modifications

BACKGROUND: In this study, we examined the effects of cyclophosphamide, methothrexate, and 5-Fluorouracil (CMF) drug combination on various aspects of learning and memory. We also examined the effects of CMF on cell proliferation and chromatin remodeling as possible underlying mechanisms to explain chemotherapy-associated cognitive dysfunction. Twenty-four adult female Wistar rats were included in the study […]

Sleep assessments in healthy school-aged children using actigraphy: concordance with polysomnography

Abstract Actigraphic (ACT) recordings are used widely in schoolchildren as a less intrusive and more extended approach to evaluation of sleep problems. However, critical assessment of the validity and reliability of ACT against overnight polysomnography (NPSG) are unavailable. Thus, we explored the degree of concordance between NPSG and ACT in school-aged children to delineate potential […]
