OBJECTIVE Evidence for a connection between stress and selected neurodegenerative diseases as well as mental disorders is analyzed. Does stress cause or exacerbate related pathophysiological disease processes? METHOD The stress phenomenon is illustrated and the impact of stress on the nervous system, neurodegenerative diseases, and mental disorders is examined. The connection between stress a...

background: occupational exposure to excessive level of copper results in many adverse health effects. objective: to measure pulmonary function, oxidative stress, and extent of dna damage in workers of a copper processing industry. methods: 30 men working in a copper processing industry and 30 men matched for age and socioeconomic status (comparison group) were included in this study. pulmonary...

Background and Objective: Spermatogenesis and oogenesis stress is a primary epigenetic element that can cause lifelong modifications in neural system functions. This study was designed to elucidate whether preconceptional stress during spermatogenesis and oogenesis affects the seizure behaviors and body weight of the offspring later in life. Materials and Methods: In this experimental study, 1...

We assess the impact of an acute restraint stress on the persistence of long term potentiation, a cellular model widely assumed to underlie learning and memory. Results indicate a restraint stress attenuates long term potentiation. This finding may have clinical implications in terms of acute stress possibly promoting deficits in cognitive functions in populations already at risk for stress-rel...

background: incidence of asthma in adolescents leads to variations in family status, roles and interaction with peers for them, which could be a source of stress and psychological tensions in them. therefore, the present study was conducted to investigate the effect of orem’s self-care model on perceived stress in adolescents with asthma. methods: in this semi-experimental study conducted from ...

During the earliest stages of Caenorhabditis elegans embryogenesis, the transcription factor SKN-1 initiates development of the digestive system and other mesendodermal tissues. Postembryonic SKN-1 functions have not been elucidated. SKN-1 binds to DNA through a unique mechanism, but is distantly related to basic leucine-zipper proteins that orchestrate the major oxidative stress response in ve...

Acute stress has an important impact on higher-order cognitive functions supported by the prefrontal cortex (PFC) such as working memory (WM). In rodents, such effects are mediated by stress-induced alterations in catecholaminergic signaling, but human data in support of this notion is lacking. A common variation in the gene encoding Catechol-O-methyltransferase (COMT) is known to affect basal ...
