αB-crystallin response to a pro-oxidant non-cytotoxic environment in murine cardiac cells: An "in vitro" and "in vivo" study.

2020

The αB-crystallin (HSPB5) protein is modulated in response to a wide variety of stressors generated by multiple physio-pathological conditions, sustained by reactive oxygen species (ROS) production. In cardiac muscle tissue, this protein regulates various cellular processes, such as protein degradation, apoptosis and the stabilization of cytoskeletal elements. In this work, we studied the role of HSPB5 expression, activation and localization in HL-1 murine cardiomyocytes exposed to pro-oxidant and non-cytotoxic H2O2 concentration, as well as in cardiac tissue isolated from mice following an acute, non-damaging endurance exercise. Our results demonstrated that HSPB5 is the most abundant HSP …

Physical exercise as an epigenetic modulator: Eustress, the "positive stress" as an effector of gene expression.

2012

Physical exercise positively influences epigenetic mechanisms and improves health. Several issues remain unclear concerning the links between physical exercise and epigenetics. There is growing concern about the negative influence of excessive and persistent physical exercise on health. How an individual physically adapts to the prevailing environmental conditions might influence epigenetic mechanisms and modulate gene expression. In this article, we put forward the idea that physical exercise, especially long-term repetitive strenuous exercise, positively affects health, reduces the aging process, and decreases the incidence of cancer through induced stress and epigenetic mechanisms. We pr…

Sources of stress and scholarly identity: the case of international doctoral students of education in Finland

2020

AbstractAlthough stressors and coping strategies have been examined in managing stress associated with doctoral education, stress continues to have a permeating and pernicious effect on doctoral students’ experience of their training and, by extension, their future participation in the academic community. International doctoral students have to not only effectively cope with tensions during their training and their socialization in their discipline but also address the values and expectations of higher education institutions in a foreign country. Considering the increase of international doctoral students in Finland, this study focuses on perceived sources of stress in their doctoral traini…

Cross‐national outcomes of stress appraisal

2012

PurposeThe present study aims to analyze the role of the appraisal of stressors as harmful and threatening (distress) and/or as opportunities and challenges (eustress) in inducing negative (burnout) and positive (engagement) effects. It compares appraisal of occupational stressors in Poland and Spain and looks for differences between these countries in the associations between different types of appraisals and their positive and negative outcomes.Design/methodology/approachThe study analyzes the equivalence of relations across cultures by constraining structural equation models to be equivalent across the Spanish (n=603) and Polish (n=147) data sets of social care services employees. Multig…

Hierarchy of Eustress and Distress: Rasch Calibration of the Valencia Eustress-Distress Appraisal Scale

2016

The purpose of the study was to uncover the hierarchy of eustress and distress appraisal and calibrate the Valencia Eustress Distress Appraisal Scale (VEDAS, Rodríguez, Kozusznik, & Peiró, 2013) using the Rasch Analysis (RA). A cross-sectional study was conducted on sample of 603 Spanish social service professionals. The VEDAS included four subscales addressing work demands that can be appraised as sources of eustress and distress. RA was carried out for eustress and distress appraisal scales. A graduation of stressful situations appraised as distress and/or as eustress was revealed. One of the greatest sources of distress and one of the lesser sources of eustress was “switching off at …

The Valencia Eustress-Distress Appraisal Scale (VEDAS): Validation of the Italian Version

2018

© 2018 by the authors. The aim of this study is to validate the Italian version of the Valencia Eustress-Distress Appraisal Scale (VEDAS). Two hundred and thirty-two Italian workers were involved in the study. Dimensionality, reliability, and concurrent validity were analyzed. Confirmatory factor analysis supported a four-dimensional structure. In addition, the Italian version of the scale showed good internal consistency and validity. The results indicate that the Italian version of the VEDAS is a valid instrument for measuring eustress and distress appraisal in the Italian context. ispartof: SUSTAINABILITY vol:10 issue:11 status: published

Distress, Eustress, or No Stress? Explaining Smartphone Users' Different Technostress Responses

2018

Technostress is common and has harmful consequences. Therefore, researchers have shown increasing interest in explaining technostress in the field of information systems (IS). While extant research merits in identifying the causes and consequences of technostress, it has not explained empirically why information technology (IT) users have different responses to similar potentially stressful IT events. Indeed, events such as smartphone failures can derive negative distress responses for some users and positive eustress responses for others. To address this gap in research, we conducted a qualitative study by interviewing users who had experienced smartphone failures. As a contribution, our f…
