Valerie Vi Thien Mac, Linda A McCauley
PURPOSE: To review factors that impact the effect of hot environments on the human body in order to develop a conceptual model of human biological response. METHODS: The organizing concept for the model development was the multilevel integration of three major factors, exposure to heat, sensitivity and adaptive capacity, and the heat stress response. Exposure of a vulnerable occupational group was used to illustrate the components of the model. FINDINGS: Components of this framework include the hazard (environmental heat stress), vulnerability factors (workplace exposure, sensitivity and adaptive capacity), and the heat stress response...

Nowadays, silver nanoparticles (AgNP) have been widely used and there are raising concerns about their potential adverse effects on organism. As for the exact toxicity mechanism of AgNP, opinions still vary and whether the released silver ions (Ag(+)) or AgNP themselves are responsible for the toxicity remains debatable. In the present study, we have designed two exposure systems where Ag(+) and AgNP coexisted but differed in quantification by using photo-reduced method with cysteine enantiomers, and their toxicities to freshwater microalgae Scenedesmus obliquus and model plant Arabidopsis thaliana were determined...

BACKGROUND: Disordered eating, ranging from occasional binge eating or restriction to behaviors associated with eating disorder diagnoses, is common among military personnel and veterans. However, there is little information on how military service affects eating habits. OBJECTIVE: To describe possible pathways between military service and disordered eating among women veterans, a high risk group. MATERIALS AND METHODS: Twenty women veterans who reported changing eating habits in response to stress participated in audio-recorded focus groups or dyadic interviews between April 2013 and October 2014...

P Vargovic, M Laukova, J Ukropec, G Manz, R Kvetnansky
Continuous exposure to cold leads to activation of adaptive thermogenesis in brown adipose tissue but also to induction of brown/beige cell phenotype in white adipose tissue. The aim of this work was to investigate whether prior exposure to immobilization (IMO) stress may affect immune response associated with adipocyte "browning" in mesenteric adipose tissue (mWAT). In the first experiment, Sprague-Dawley rats were exposed to acute (3 h) or prolonged (7 days) cold exposure (4 ± 1 °C). 7-day cold stimulated gene expression of uncoupling protein 1 and other "browning"-associated factors...

PURPOSE: Effort-reward imbalance (ERI) is a well-tested work-related stress model with three components, the two extrinsic components "efforts" and "rewards" and the one intrinsic component "overcommitment". While an imbalance between "efforts" and "rewards" leads to strain reactions, "work-related overcommitment" (OC) has been described as a personal characteristic with a set of attitudes, behaviours, and emotions reflecting excessive striving combined with a strong desire for approval...

PURPOSE: Postgraduate year 1 (PGY1) doctors suffer from high levels of psychological distress, yet the contributory factors are poorly understood. This study used an existing model of workplace stress to explore the elements most pertinent to PGY1 doctors. In turn, the data were used to amend and refine the conceptual model to better reflect the unique experiences of PGY1 doctors. METHOD: Focus groups were undertaken with PGY1 doctors working at four different health services in Victoria, Australia...

BACKGROUND: Work-related stress and burnout syndromes are unfortunately common comorbidities found in health professionals. However, burnout syndrome has only been partly and episodically assessed for community pharmacists whereas these professionals are exposed to patients' demands and difficulties every day. Prevalence of burnout, associated comorbidities and coping strategies were assessed in pharmacy teams (pharmacists and pharmacy technicians) in French community pharmacies. METHODS: This online survey was performed by emails sent to all French community pharmacies over 3 months...

BACKGROUND: Several studies have shown that professional drivers are at risk of developing work-related stress. Stress may be responsible for a variety of adverse effects and may also be associated with an increased number of accidents. OBJECTIVE: Perform an integrated, objective and subjective evaluation of work-related stress in bus drivers, that also considered the role of personality traits. METHODS: Salivary α-amylase and cortisol were measured in 42 bus drivers...

Advances in HIV treatment through highly active antiretroviral therapy (HAART) have led to a steady decline in HIV-related mortality rates. However, HAART requires adherence to strict and often complicated medication regimens, and nonadherence to HAART can significantly decrease its effectiveness. Depression has consistently shown a robust association with medication nonadherence; consequently, numerous psychological interventions have been developed to target depression and increase medication adherence among HIV-infected individuals...

Transendothelial migration of cancer cells is a critical stage in cancer, including breast cancer, as the migrating cells are generally believed to be highly metastatic. However, it is still challenging for many existing platforms to achieve a fully covering endothelium and to ensure transendothelial migration capability of the extracted cancer cells for analyses with high specificity. Here, we report a microfluidic device containing multiple independent cell collection microchambers underneath an embedded endothelium such that the transendothelial-migrated cells can be selectively collected from only the microchambers with full coverage of an endothelial layer...

Adipose tissue is fundamental to energy balance, which underpins fitness and survival. Knowledge of adipose regulation in animals that undergo rapid fat deposition and mobilisation aids understanding of their energetic responses to rapid environmental change. Tissue explants can be used to investigate adipose regulation in wildlife species with large fat reserves, when opportunities for organismal experimental work are limited. We investigated glucose removal, lactate, glycerol and NEFA accumulation in media, and metabolic gene expression in blubber explants from wild grey seals...

BACKGROUND: Hospital staff experience high level of work stress and they have to find strategies to adapt and react to it. When they perceive emotional exhaustion and job dissatisfaction in response to constant work stress, one reaction might be emotional withdrawal. This emotional distancing can be seen as an adaptive strategy to keep 'functionality' in the job. Both, perception of emotional exhaustion and emotional distancing as a strategy, can be operationalized as 'Cool Down'. We assume that work stress associated variables are positively associated with Cool Down reactions, while internal and external resources are negatively associated and might function as a buffer against emotional distancing...

BACKGROUND: Traction Force Microscopy (TFM) is a widespread technique to estimate the tractions that cells exert on the surrounding substrate. To recover the tractions, it is necessary to solve an inverse problem, which is ill-posed and needs regularization to make the solution stable. The typical regularization scheme is given by the minimization of a cost functional, which is divided in two terms: the error present in the data or data fidelity term; and the regularization or penalty term...

Although sociologists have long been interested in the stratification of emotions, the occupational stratification of anger has been investigated in only a few general population studies. Through analyses of data representative of workers in Toronto, we evaluate the hypothesis that workplace hierarchical position, defined by supervisory level, has an inverted u-shaped association with the frequency of anger about work. We also evaluate the more specific hypothesis that the difference in work-related anger between front-line supervisors and nonsupervisory workers will be relatively larger among workers in the commodified services sector than other sectors...

Drawing on interview and focus group data, this article explores research undertaken as part of a larger research project exploring precarity in the nonprofit employment services sector in a mid-sized Canadian city. We critically survey major legislative changes to Canadian employment and income security policies and programs, including the restructuring of work and labor relations, growth of performance-based contracting-out, erosion of intergovernmental transfers, worker stress, and emotional tolls. Our study's results demonstrate how employment precarity in the nonprofit employment services sector is amplified by top-down and centralized relationships with funding partners and policymaking divorced from the employment experiences of frontline staff...
