'Salinity Stress: Physiological Constraints and Adaptive Mechanisms'
, 2012A significant part of the world's land area is salt-affected. Most crops are not able to handle large amounts of salt without a negative impact on their growth and metabolism, so understanding the physiological mechanisms by which plants deal with ...

Physiology and Abiotic Stresses
2015Clusterbean is a robust crop and copes with almost all the physiological and abiotic stresses; however, for good crop productivity these stresses should be properly addressed. The physiological aspects associated with seed maturation, seed coat colour, germination, seedling/plant growth, seed yield and seed storage in clusterbean are taken in hand.

Physiologic stress and tooth contact
Journal of Periodontal Research, 1969This investigation was undertaken to study the relationship between physiologic data, such as pulse rate and stroke volume, to the occurrence of tooth contacts. The tooth contacts were monitored in the intercuspal (I.C.) position and lateral or eccentric to this position with the aid of radio‐transmitters constructed into dental bridgework as described

The Physiology of Abiotic Stresses
2012Plants are often exposed to several adverse environmental conditions that potentially generate stress and thus negatively affect their growth and productivity. Understanding the physiological responses of crops to stress conditions is essential to minimizing the deleterious impacts of stress and maximizing productivity.

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 ...

BioScience, 1980
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 ...

Physiological functions of glucocorticoids in stress and their relation to pharmacological actions.
Endocrine reviews, 1984Almost any kind of threat to homeostasis or stress will cause plasma glucocorticoid levels to rise. The increased levels have traditionally been ascribed the physiological function of enhancing the organism's resistance to stress, a role well recognized ...
