Chronic stress is a public health problem that affects a significant part of the population. While the physiological damage it causes is under ongoing scrutiny, its behavioral effects have been overlooked. This is one of the first studies to examine the relation between chronic stress and decision-making, using a standard lottery paradigm. We measured risk taking in the gain domain through bina...

BACKGROUND Prolonged stress leads over time to allostatic load on the body and is likely to exacerbate a disease process. Long-term of stress exposure is one of a risk factor for metabolism-related diseases such as obesity and type 2 diabetes. However, the relationship between chronic stress and non-alcoholic fatty liver disease (NAFLD) remain unknown. METHODS To address the hypothesis that c...

Increased vulnerability to psychiatric disorders, such as schizophrenia, has been associated with higher levels of stress. In the early development of the central nervous system, changes in function of glutamatergic N-Methyl-D-aspartate (NMDA) receptors can possibly result in the development of psychosis, cognitive impairment and emotional dysfunction in adulthood. Thus, in this study we examin...

While modernization has dramatically increased lifespan, it has also witnessed that the nature of stress has changed dramatically. Chronic stress result failures of homeostasis thus lead to various diseases such as atherosclerosis, non-alcoholic fatty liver disease (NAFLD) and depression. However, while 75%-90% of human diseases is related to the activation of stress system, the common pathways...

OBJECTIVE This article aims to examine the role of work stress as a moderating variable in the chronic pain-depression association, as well as sex differences in this link. METHODS The analyses were carried out using the Canadian Community Health Survey Cycle 1.1. Key variables were chronic pain conditions (fibromyalgia, arthritis/rheumatism, back problems, and migraine headaches), work stres...

background: recently, it has been revealed that tyrosine kinase inhibitors (tkis) act through inducing both oxidative and endoplasmic reticulum (er) stress in chronic myeloid leukemia cells. however, er stress signaling triggers both apoptotic and survival processes within cells. nevertheless, mechanisms by which tkis avoid the pro-survival effects are not clear. the aim of this study was to ev...

Background Chronic stress induces male reproductive dysfunction; however, the involved mechanisms are not clear. It has been suggested that the gonadotrophin-inhibitory hormone, known as RF-amide related peptide (RFRP) in mammalian species, may mediate this inhibitory effect of stress. The objective of the present study was to compare the effect of chronic stress and glucocorticoids receptor an...

Major depressive disorder patients present chronic stress and decreased immunity. The Wistar-Kyoto rat (WKY) is a strain in which the hypothalamic-pituitary-adrenal axis is overactivated. To determine whether chronic stress induces changes in corticosterone levels and splenic lymphoid tissue, 9-week-old male rats were subject to restraint stress (3 h daily), chemical stress (hydrocortisone trea...
