Immediate and long-term effects of psychological stress during adolescence in cardiovascular function: comparison of homotypic vs heterotypic stress regimens
(2015)
Adolescence has been proposed as an ontogenic period of vulnerability to stress. Nevertheless, the impact of stressful events during adolescence in cardiovascular activity is poorly understood. Therefore, the purpose of ...
Influence of pre-existing hypertension on neuroendocrine and cardiovascular changes evoked by chronic stress in female rats
(2018-11-01)
This study investigated neuroendocrine, autonomic, and cardiovascular changes evoked by daily exposure to the same type of stressor (homotypic) or different aversive stressor stimuli (heterotypic) in 60-days-old female ...
Effects of simultaneous exposure to stress and nicotine on nicotine-induced locomotor activation in adolescent and adult rats
(Associação Brasileira de Divulgação Científica (ABRADIC), 2012-01-01)
Preclinical studies have shown that repeated stress experiences can result in an increase in the locomotor response to the subsequent administration of drugs of abuse, a phenomenon that has been termed behavioral ...
TRPM4 activation by chemically- and oxygen deprivation-induced ischemia and reperfusion triggers neuronal death
(Taylor & Francis, 2017)
Cerebral ischemia-reperfusion injury triggers a deleterious process ending in neuronal death. This process has two components, a glutamate-dependent and a glutamate-independent mechanism. In the glutamate-independent ...
Reactive oxygen and nitrogen species modulate the ex-vivo effects of LPS on platelet adhesion to fibrinogen
(Pergamon-elsevier Science LtdOxfordInglaterra, 2011)
Cardiovascular and metabolic consequences of the association between chronic stress and high-fat diet in rats
(2018-05-04)
Obesity and chronic stress are considered independent risk factors for the development of cardiovascular diseases and changes in autonomic system activity. However, the cardiovascular consequences induced by the association ...
Ultraviolet-B and water stress effects on growth, gas exchange and oxidative stress in sunflower plants
(Springer, 2008-07-01)
The effects and interaction of drought and UV-B radiation were studied in sunflower plants (Helianthus annuus L. var. Catissol-01), growing in a greenhouse under natural photoperiod conditions. The plants received approximately ...
Stress induces behavioral sensitization, increases nicotine-seeking behavior and leads to a decrease of CREB in the nucleus accumbens
(Pergamon-Elsevier B.V. Ltd, 2012-05-01)
Experimental evidence shows that exposure to stress engenders behavioral sensitization and increases drug-seeking and leads to intense drug taking. However the molecular mechanisms involved in these processes is not well ...
