Annealing effect on temperature stability and mechanical stress at the “CdxPb1−xS film – substrate” interface

open access: yesChimica Techno Acta, 2020
The article establishes the upper temperature steadiness limit of СdxPb1-xS supersaturated solid solutions obtained by chemical bath deposition. СdxPb1-xS (x = 0.06; 0.122; 0.176) and (x = 0.02–0.05) films remained stable under the heating up to 405–410 ...

Stress mechanisms in hypertension [PDF]

open access: yesPostgraduate Medical Journal, 1986
Summary Recent studies of stress mechanisms in hypertension have focussed on the cardiovascular and neuroendocrine reactions to challenging or threatening psychosocial stimuli. Fixed hypertension may develop in some animal models following chronic exposure to psychosocial conflict.

The Role of Mechanical Stresses in Angiogenesis [PDF]

open access: yesCritical Reviews in Biomedical Engineering, 2005
Angiogenesis is the formation of new capillary blood vessels from preexisting vessels. It is involved in many normal and diseased conditions, as well as in the application of tissue-engineered products. There has been extensive effort made to develop strategies for controlling pathological angiogenesis and for promoting vascularization in biomedical ...

Epigenetic mechanisms in stress and adaptation [PDF]

open access: yesBrain, Behavior, and Immunity, 2011
Epigenetic mechanisms are processes at the level of the chromatin that control the expression of genes but their role in neuro-immuno-endocrine communication is poorly understood. This review focuses on epigenetic modifications induced by a range of stressors, both physical and psychological, and examines how these variations can affect the biological ...

Stress Mechanisms and Metabolic Complications

open access: yesHormone and Metabolic Research, 2007
Stress can be defined as a state of threatened homeostasis or disharmony. An intricate repertoire of physiologic and behavioral responses is mobilized under stressful situations forming the adaptive stress response that aims to reestablish the challenged body equilibrium. The hypothalamic-pituitary-adrenal axis and the central and peripheral components
