Stress and adrenal function

Journal of Experimental Zoology, 1984
AbstractThe natural environment is composed of various potentially hostile stressors. It is a basic requirement of life that the cells of an organism must be maintained within closely defined physiological limits. The maintenance of a constant interior mileu results from physiological and behavioural homeostatic adaptations.

Application of Stress Functions to Initial Stress Problems

Journal of Applied Mechanics, 1978
The governing equations of the linear initial stress problem are obtained from the pertinent equations of large deformation analysis. These equations are then cast in the framework of a variational statement. The functional has the incremental stresses and displacements as competing functions. However, in contrast to mixed formulations the displacement

Stress and cognitive functioning in sport

Journal of Sports Sciences, 1989
This paper considers the relationship between stress and cognitive functioning and discusses some of the concepts and methods that may be adopted to examine the relationship between stress and sports performance. It considers only that literature that may be relevant to, or furthers, the understanding of sports performance under competitive stress. One

On Velocity Potentials and Stress Functions

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1978
AbstractBy using a variational principle which is complementary to Hamilton's Principle, and by introducing new stress functions, the domain of application of stress functions has been extended to problems of elastodynamics. The Euler‐Lagrange equations associated with the new stress functions emerge as additional compatibility conditions involving the

The Stress Clock Function in Viscoelasticity

Journal of Rheology, 1980
When subjected to creep test, aluminum exhibits characteristics which are analogous to those of thermorheologically simple material in the sense that on a plot of logarithm of creep function versus logarithm of time the curves corresponding to different stresses have the same shape so that they all could be shifted to form a master curve. Based on this

Platelet Function in Surgical Stress

Thrombosis and Haemostasis, 1985
SummaryTen patients for elective cholecystectomy were studied pre-, per- and postoperatively. All had neurolept anesthesia. Plasma concentrations of β-TG, TXB2 and 5-HT and intraplatelet 5-HT were measured. Aggregation to ADP was recorded.Serum cortisol concentration was used as index of the stress response, showing peroperative increase and ...

Stress Functions for Rotating Plates

Journal of Applied Mechanics, 1956
Abstract The general theory of two-dimensional bodies subjected to body forces is well known. However, except for a few examples in which gravity is the body force, and various examples of rotationally symmetric rotating disks, comparatively little appears to have been done with this theory.

The effect of stress on menstrual function

Trends in Endocrinology & Metabolism, 2004
Historically difficult to define, stress is, in one sense, the factor that stressors have in common in their impact on the body. Menstrual function is disrupted by stressors that activate the hypothalamic-pituitary-adrenal (HPA) axis; this activation is part of a catabolic response of the whole body that mobilizes metabolic fuels to meet energy demand.

Functions of p21Waf1 in Norm and in Stress

Molecular Biology, 2004
Cyclin-dependent kinase inhibitor p2(Waf1/Cip1/Sdi1/CAP20) plays the key part in cell cycle arrest at the G1/S checkpoint in response to DNA damage, and is involved in the assembly of active cyclin-kinase complexes, in particular, cyclin D-Cdk4/6. Recent studies extended the range of known p21Waf1 functions.
