The empathic, physiological resonance of stress
Social Neuroscience, 2012Physiological resonance between individuals is considered fundamental to the biological capacity for empathy. Observers of pain and distress commonly exhibit increases in reported distress, autonomic arousal, facial mimicry, and overlapping neural activity.

Stress response physiology of thermophiles
Archives of Microbiology, 2017Thermo (or hyperthermo) philic microorganisms are ubiquitous having a wide range of habitats from freshly fallen snow to pasteurized milk to geothermal areas like hot springs. The variations in physicochemical conditions, viz., temperature, pH, nutrient availability and light intensity in the habitats always pose stress conditions for the inhabitants ...

This quotation and the subsequent publication of the details of the General Adaptation Syndrome (Selye 1937) have become the basis for a vast number of studies on the subject of stress in animals. Despite the fact that the term stress seems imprecise because it means different things to different people, the broad concept has proved to be remarkably ...

Stress hormones: physiological stress and regulation of metabolism
Current Opinion in Pharmacology, 2009Stress, defined as a state of threatened homeostasis, mobilizes a complex spectrum of adaptive physiologic and behavioral responses that aim to re-establish the challenged body homeostasis. The hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS) constitute the main effector pathways of the stress system, mediating its ...

Environmental Constraints and Stress Physiology
2010Grapevines are often exposed to suboptimal growing conditions that cause environmental or abiotic stress. Such resource limitation leads to acclimation processes throughout the plant that shift investment to those organs or processes that favor acquisition of the limiting resource.

Measurement of physiological stress
Proceedings of the IEEE 23rd Northeast Bioengineering Conference, 2002In this tutorial paper, the methods presently used for measuring the degree of stress and relaxation in human physiology are discussed. Measurements include heart rate variability, respiration, blood levels of substance such as cortisol and catecholamine levels, EEG effects and the change in peripheral blood flow.

Physiology of Stress Resistance
1995The terms stress and stress resistance are used in the same way for plants as for man and other animals. Stress (= State of tension) signifies the effects of a “load” on the organism, caused by the influences of external factors (stress factors) which lead to an impairment or reduction in metabolism or development.
