Environmental Constraints and Stress Physiology

2010
Grapevines 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, 2002
In 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

1995
The 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.

Changes in intestinal microbiota composition and metabolism coincide with increased intestinal permeability in young adults under prolonged physiological stress.

American Journal of Physiology - Gastrointestinal and Liver Physiology, 2017
The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military training environment to determine

Stress Hormones, Physiology, and Behavior

2019
Stress, be it physical or psychological, can have a devastating long-term impact on an individual’s development, health, and well-being, and yet can be adaptive in the short term (e.g., promoting immediate survival, triggering the desire to remedy social conflict).

BIRTH ORDER AND PHYSIOLOGICAL STRESS RESPONSE

Child Development, 1970
Studies of the relation between birth order and anxiety have reported inconsistent results. However the measures of anxiety employed have often been either subjective or indirect. The purpose of the present study was to assess the relation between birth order and anxiety using direct and objective measures.
