Avoiding handling-induced stress in poultry: use of uniform parameters to accurately determine physiological stress

Effect of Melatonin Premedication on Some Physiological Parameters and Reduction of Oxidative Stress in Tagetes etecta Seedlings under Salt Stress

Salinity is one of the most important environmental stresses which affect the growth of plants. Most of the plants are sensitive to salt stress at the seedling stage, so the growth of them in salt-water accompanies with problems. Various agronomic and physiological practices (treatments) are applied to minimize the adverse effects of salinity on plant growth and using of plant growth regulator ...

Model of physiological stress in chickens 1. Response parameters.

A model was developed to study stress in chickens. Continuous administration of adrenocorticotropic hormone was employed (ACTH) using physiological mini-osmotic pumps. A validation of controls for this procedure showed that nonhandled (NHCON), sham surgical procedure for pump implantation (SMCON) and surgical implantation of a pump delivering saline (SALCON) were all acceptable controls. Contin...

Responses of Almond Genotypes to Osmotic Stress Induced In Vitro

Drought is one of the major limitations to crop production worldwide. This study was conducted to evaluate the response of five almond genotypes and peach×almond hybrid GF to drought stress in vitro, and screening drought tolerance. Explants subjected to polyethylene glycol osmotic stress ( , , and . % WV) on the MS medium. Increasing PEG level in the medium significantly reduced fresh weight a...

PHYSIOLOGICAL STRESS (RE)ACTIVITY IN RELATION TO SUBSTANCE USE DISORDERS Physiological stress (re)activity in adolescents from the general population

Evaluation of environmental heat stress on physiological parameters

Background Thermal component of the atmospheric environment is an important issue which is related to human's health. Thermal environment includes both heat exchange conditions (stress) and the physiological response (strain). The aim of this study was to measure the association of heat indices (PSI, HSI, Humidex) especially subjective one (STI) with some physiological parameters (Blood pressur...
