A Comparison of Physical Activity Levels, Sleep Disrupting Behavior, and Stress/Affective Distress as Predictors of Sleep as Indexed by Actigraphy.

J Phys Act Health 2021 Jun 13:1-12. Epub 2021 Jun 13.

Background: Several behaviors have been reported to interfere with sleep in otherwise healthy adults, including low physical activity (PA) levels. However, few studies have compared low PA with the other behavioral risk factors of objective sleep impairment, despite the behavior tending to cooccur in highly stressed and affectively distressed individuals. Thus, the authors compared objective and subjective measures of PA and other potential sleep disrupting behaviors as predictors of objective sleep (sleep onset latency, actual sleep time, total sleep duration, awake time, and sleep efficacy) at baseline (T1) and 3 months later (T2).

Combined toxicity of nano-TiO and Cd to Scenedesmus obliquus: Effects at different concentration ratios.

J Hazard Mater 2021 Jun 9;418:126354. Epub 2021 Jun 9.

Shenzhen International Graduate School, Tsinghua University, Shenzhen 518055, China.

The continuous release of manufactured nanomaterials (MNMs) to environments raised concerns on their combined toxicological risks with co-existing contaminants, since MNMs might severely alter the environmental behavior and fate of the contaminants. In this study, the combined toxicity of nano-sized titanium dioxide (nTiO) and cadmium (Cd) to the green alga Scenedesmus obliquus and the underlying physicochemical mechanisms were investigated for the first time at different concentration ratios of Cd to nTiO to closely mimic the realistic environment scenarios where the concentration ratios of nTiO to other contaminants are constantly changing. Our results suggested that under the co-exposure to different concentration ratios of Cd to nTiO, the co-exposure contaminants exhibited three different combined toxicity modes (antagonistic, partially additive, and synergistic).

The effect of vascular health factors on white matter microstructure mediates age-related differences in executive function performance.

Cortex 2021 May 25;141:403-420. Epub 2021 May 25.

The University of Texas at Dallas, School of Behavioral and Brain Sciences, Center for Vital Longevity, Dallas, TX, USA. Electronic address:

Even within healthy aging, vascular risk factors can detrimentally influence cognition, with executive functions (EF) particularly vulnerable. Fronto-parietal white matter (WM) connectivity in part, supports EF and may be particularly sensitive to vascular risk. Here, we utilized structural equation modeling in 184 healthy adults (aged 20-94 years of age) to test the hypotheses that: 1) fronto-parietal WM microstructure mediates age effects on EF; 2) higher blood pressure (BP) and white matter hyperintensity (WMH) burden influences this association.
