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.

Internal Stress in a Model Elasto-Plastic Fluid [PDF]

open access: yes, 2005
Plastic materials can carry memory of past mechanical treatment in the form of internal stress. We introduce a natural definition of the vorticity of internal stress in a simple two-dimensional model of elasto-plastic fluids, which generates the internal

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

Periodic Mechanical Stress INDUCES Chondrocyte Proliferation and Matrix Synthesis via CaMKII-Mediated Pyk2 Signaling

open access: yesCellular Physiology and Biochemistry, 2017
Background/Aims: Periodic mechanical stress can promote chondrocyte proliferation and matrix synthesis to improve the quality of tissue-engineered cartilage. Although the integrin β1–ERK1/2 signal cascade has been implicated in periodic mechanical stress-
