This review focuses on the mechanisms of stress response in the synovial tissue of rheumatoid arthritis. The major stress factors, such as heat stress, shear stress, proinflammatory cytokines and oxidative stress, are discussed and reviewed, focusing on their potential to induce ...

ABSTRACT Objective: The aim of this study was to investigate the effects of acute physical and psychological stress and temporary central nucleus of the amygdala (CeA) block on stress-induced visceral hypersensitivity. Methods: Forty two male Wistar rats were used in this study...

Numerous studies demonstrate links between chronic stress and indices of poor health, including risk factors for cardiovascular disease and poorer immune function. Nevertheless, the exact mechanisms of how stress gets “under the skin” remain elusive. We investigated the hypothesi...

Abstract Stress affects the productivity and fertility of cattle. Stress causes strain and individual animals experience different amounts of strain in response to the same amount of stress. The amount of strain determines the impact of stress on fertility. Typical stresses exper...

Este estudo investigou a influência do stress e da raiva de mães hipertensas e normotensas no nível de stress dos filhos. A amostra foi composta por dois grupos, sendo um composto por 10 mães hipertensas, e o mais velho de seus filhos, a faixa etária entre 6 e 10 anos, sem restri...

This study of stress-related antinuclear antibody (ANA) reactivity was undertaken with the objective of improving clinical ANA testing. ANA was determined by parallel enzyme-linked immunosorbent assays of crude nuclear protein antigen extracted from HEp-2 cells either grown under...

Chronic stress exposure has been reported to induce dendritic remodeling in several brain regions, but it is not known whether individual neural circuits show distinct patterns of remodeling. The current study tested the hypothesis that the projections from the infralimbic (IL) a...

This work presents a hybrid experimental theoretical technique for residual stresses analysis of mechanical components. It was used the blind hole technique along with the Electronic Speckle Pattern Interferometry (ESPI) method and Airy stress functions for the determination of t...

O presente estudo teve por objetivos, levantar o perfil sócio-demográfico e cultural, de auxiliares de enfermagem, avaliar o grau e presença de sintomas de stress, avaliar e descrever reajustamento social tecendo relação entre variáveis relacionadas ao labor e o stress. Participa...

Neste trabalho, apresentamos uma investigação realizada com professores, no qual se procura determinar a vulnerabilidade ao stress; identificar as principais fontes de stress; estabelecer as principais estratégias de coping; analisar se as estratégias deste condicionam a presença...

Abstract Crocus sativus L., Iridaceae, has been used worldwide in traditional medicinefor treatment ofsome neurological disorderssuch as depression. Post-traumatic stress disorder is a mental disorder developed in peoplewho experience stressful events. Since stress has been propo...

Foi estudada uma amostra de 28 professoras do ensino fundamental quanto à interação entre stress, burnout e sentido e quanto à eficácia de dois tipos de treinamento para redução do stress excessivo. Utilizou-se como instrumentos de aferição o Inventário de Sintomas de Stress de L...

The main purpose of this research was to study the stress level in journalists working on television, specially reporters and cameramen, and know the relationship level with the professional performance. The aim was also to compare the stress related to the abilities and technica...

Previous work has implicated the Hog1 stress-activated protein kinase (SAPK) in osmotic and oxidative stress responses in the human pathogen Candida albicans. In this study, we have characterized the role of Hog1 in mediating these and other stress responses in C. albicans. We pr...

Abstract Dynamic compression behaviors of density-homogeneous and density-graded irregular honeycombs are investigated using cell-based finite element models under a constant-velocity impact scenario. A method based on the cross-sectional engineering stress is developed to obtain...

Sometimes organizations described as benevolent, focusing on stable procedures and cordial relations are regarded as examples of collective indolence and likely to be out-competed by aggressive, merciless and stress-prone organizations. In this paper we suggest that some managers...

Environmental stress activates sigma B, the general stress response sigma factor of Bacillus subtilis, by a pathway that is negatively controlled by the RsbX protein. To determine whether stress activation of sigma B occurs by a direct effect of stress on RsbX, we constructed B. ...

Active repression of protein synthesis protects cells against protein malfolding during endoplasmic reticulum stress, nutrient deprivation and oxidative stress. However, long-term adaptation to these conditions requires synthesis of new stress-induced proteins. Phosphorylation of...

Stress-induced activation of the Bacillus subtilis transcription factor ςB is transitory. To determine whether the process that limits ςB activation is itself triggered by stress, B. subtilis strains in which the stress pathway was artificially activated by the induced expression...

Para muitos autores, o stress está negativamente relacionado ao desempenho individual. Algumas evidências, entretanto, sugerem que a performance em determinada tarefa será mais baixa sob níveis muito reduzidos ou muito elevados de stress, e ótima sob níveis moderados de stress. O...

Chronic Mild Stress-induced anhedonia is an animal experimental model that exposes rats to a mild stressors regime for a long period of time. This model was proposed in 1987 Willner, Towell, Sampson, Sophokleus e Muscat. The purpose of the present study was to verify whether the ...
