Insights from multiple stable isotopes (C, N, Cl) into the photodegradation of herbicides atrazine and metolachlor

Author(s): Levesque-Vargas M; Ohlund L; Sleno L; Gélinas Y; Höhener P; Ponsin V;

Many processes can contribute to the attenuation of the frequently detected and toxic herbicides atrazine and metolachlor in surface water, including photodegradation. Multi-element compound-specific isotope analysis has the potential to decipher between these different degradation pathways as Cl is a promising tool for both pathway identification and a s ...

The effect of micro-vessel viscosity on the resonance response of a two-microbubble system

Author(s): Yusefi H; Helfield B;

Clinical ultrasound contrast agent microbubbles remain intravascular and are between 1-8 µm in diameter, with a volume-weighted mean size of 2-3 µm. Despite their worldwide clinical utility as a diagnostic contrast agent, and their continued and ongoing success as a local therapeutic vector, the fundamental interplay between microbubbles - including bubbl ...

Asymmetric autocatalytic reactions and their stationary distribution

Author(s): Gallinger C; Popovic L;

We consider a general class of autocatalytic reactions, which has been shown to display stochastic switching behaviour (discreteness-induced transitions (DITs)) in some parameter regimes. This behaviour was shown to occur either when the overall species count is low or when the rate of inflow and outflow of species is relatively much smaller than the rate ...

The Effects of Weekly Levels of Supervisor Support and Workload on Next Week Levels of Well-Being, Satisfaction, and Performance as Mediated by Weekend Work Recovery

Author(s): Cheyroux P; Morin AJS; Colombat P; Blechman Y; Gillet N;

This diary study sought to examine the direct and indirect effects of individuals' perceptions of supervisor support and workload during a work week (week 1) on their well-being, satisfaction, and performance at work during the following work week (week 2) as mediated through the quality of their weekend work recovery experiences (psychological detach ...

Low Back Pain During and After Spaceflight: A Systematic Review with Meta-Analysis

Author(s): Ceniza-Bordallo G; Zimmermann E; Vigouroux M; Niburski K; Fortin M; Ouellet J; Cata JP; Ingelmo PM;

Space flights can produce physiological changes in the spine, leading to the development of acute and chronic pain in passengers. However, there is a lack of comprehensive literature exploring physiological spine changes and acute and chronic pain in space passengers (astronauts and animals). The ...

Developmental heterogeneity of school burnout across the transition from upper secondary school to higher education: A 9-year follow-up study

Author(s): Nadon L; Morin AJS; Gilbert W; Olivier E; Salmela-Aro K;

This study utilized piecewise linear growth mixture analysis to examine the developmental heterogeneity of school burnout among a sample of 513 (67.6% females) Finnish students as they transitioned from upper secondary school to higher education (ages 17-25 years). Encompassing five measurement points (two before the transition and three after), our resul ...

Resilience, Stress, and Mental Health Among University Students: A Test of the Resilience Portfolio Model

Author(s): Fang S; Barker E; Arasaratnam G; Lane V; Rabinovich D; Panaccio A; O' Connor RM; Nguyen CT; Doucerain MM;

In recent years, post-secondary students' mental health has become an important public health concern. However, studies examining protective factors of mental health among students and during challenging times are limited. Guided by the strength-based Resilience Portfolio Model and following ...

Impact of a national dementia research consortium: The Canadian Consortium on Neurodegeneration in Aging (CCNA)

Author(s): Chertkow H; Phillips N; Rockwood K; Anderson N; Andrew MK; Bartha R; Beaudoin C; Bélanger N; Bellec P; Belleville S; Bergman H; Best S; Bethell J; Bherer L; Black S; Borrie M; Camicioli R; Carrier J; Cashman N; Chan S; Crowshoe L; Cuello ...

The Canadian Consortium on Neurodegeneration in Aging (CCNA) was created by the Canadian federal government through its health research funding agency, the Canadian Institutes for Health Research (CIHR), in 2014, as a response to the G7 initiative to fight dementia. Two five-year funding cycles ( ...

Effects of chronodisruption and alcohol consumption on gene expression in reward-related brain areas in female rats

Author(s): Meyer C; Schoettner K; Amir S;

Circadian dysfunction caused by exposure to aberrant light-dark conditions is associated with abnormal alcohol consumption in humans and animal models. Changes in drinking behavior have been linked to alterations in clock gene expression in reward-related brain areas, which could be attributed to either the effect of chronodisruption or alcohol. To date, ...

Reduced 17β-estradiol following ovariectomy induces mitochondrial dysfunction and degradation of synaptic proteins in the entorhinal cortex

Author(s): Olajide OJ; Batallán Burrowes AA; da Silva IF; Bergdahl A; Chapman CA;

Reductions in circulating estrogens can contribute to cognitive decline, in part by impairing mitochondrial function within the hippocampal region. The entorhinal cortex provides the hippocampus with its main cortical input and, to assess the impact of estrogen deficiency on mitochondrial respiration and synaptic proteins in the entorhinal cortex, wildtyp ...
