Decreased endothelium-dependent vasoconstriction to noradrenaline in acute-stressed rats is potentiated by previous chronic stress: Nitric oxide involvement
(Elsevier B.V., 1998-01-01)
1. The objective was to determine whether nitric oxide participates in stress adaptive responses. Acute stress (AS) decreased endothelium-dependent vasoconstriction to noradrenaline (NA) in rat aorta [control rat (CR) ...

The importance of androgen on noradrenergic responses of vas deferens isolated from acutely stressed rats
(Academic Press Ltd, 1999-10-01)
This study investigated the importance of androgen on responses to alpha and beta (norepinephrine) and alpha(1) (phenylephrine and methoxamine) agonists in vasa deferentia isolated from adult, immature, cryptorchid, and ...
Acute stressor-selective effect on total plasma homocysteine concentration in rats
(Elsevier B.V., 2004-02-01)
Stress produces several physiological and behavioral alterations that increase cardiovascular morbidity and mortality. Nonetheless, there is a dearth of studies that have evaluated the effects of stress on total plasma ...
Emotional stress and cardiovascular complications in animal models: A review of the influence of stress type
(2016-06-01)
Emotional stress has been recognized as a modifiable risk factor for cardiovascular diseases. The impact of stress on physiological and psychological processes is determined by characteristics of the stress stimulus. For ...
Techniques to minimize the effects of acute heat stress or chronic in broilers
(2019-01-01)
High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat ...
Human sensory processing under acute psychosocial stress : neurophysiological correlates
(2021)
The acute state of stress can alter some sensory systems by modifying the sensitivity and specificity of sensory processing. Limbic areas, like the amygdala and locus coeruleus, may have a fundamental role in this process. ...
Acute stress or systemic insulin injection increases flunitrazepam sensitive-GABAA receptor density in synaptosomes of chick forebrain: Modulation by systemic epinephrine
(Taylor & Francis Ltd, 2009-06-07)
Interactions between acute stress and systemic insulin and epinephrine on GABAA receptor density in the forebrain were studied. Here, 10 day-old chicks were intraperitoneally injected with insulin, epinephrine or vehicle ...
