TLDR
Together these agents appear to determine the complex physiologic responses to a variety of stressors.Abstract:
Stress stimulates several adaptive hormonal responses. Prominent among these responses are the secretion of catecholamines from the adrenal medulla, corticosteroids from the adrenal cortex, and adrenocorticotropin from the anterior pituitary. A number of complex interactions are involved in the regulation of these hormones. Glucocorticoids regulate catecholamine biosynthesis in the adrenal medulla and catecholamines stimulate adrenocorticotropin release from the anterior pituitary. In addition, other hormones, including corticotropin-releasing factor, vasoactive intestinal peptide, and arginine vasopressin stimulate while the corticosteroids and somatostatin inhibit adrenocorticotropin secretion. Together these agents appear to determine the complex physiologic responses to a variety of stressors.read more

Physiological stress in broilers: ramifications on nutrient digestibility and responses.
W. S. Virden,M. T. Kidd +1 more
TL;DR: This review examines the physiological mechanisms that activate and control stress, as well as the effects of stress on immunity, metabolism, and broiler performance, and nutrients that have been shown to have the potential for stress reduction or amelioration.

Stress physiological responses to tourist pressure in a wild population of European pine marten.
Isabel Barja,Gema Silván,Stefano Rosellini,Ana Piñeiro,A. González-Gil,Laura Camacho,J. C. Illera +6 more
TL;DR: Wild populations of European pine marten showed stress physiological response induced by the tourist pressure and this response is higher during reproductive season.

A unifying hypothesis of Alzheimer's disease. IV. Causation and sequence of events.
TL;DR: Cumulative evidence suggests that the brain in aging and AD actively adapts to the progressive fuel deprivation and suggests that senile plaques are the dump rather than the driving force of AD.

Male-female differences in effects of parental absence on glucocorticoid stress response.
TL;DR: Examination of family environments and hormone profiles of 316 individuals residing in a rural village on the east coast of Dominica indicates that early family environment has significant effects on endocrine response throughout male life histories.

Drug-induced disorders of glucose metabolism. Mechanisms and management.
TL;DR: The hypoglycaemic effects of a drug may be turned to a therapeutic advantage in patients with diabetes mellitus or those who are at risk of developing glucose intolerance, despite the large number of anecdotal reports of drug-induced disturbances of glucose metabolism.

Characterization of a 41-residue ovine hypothalamic peptide that stimulates secretion of corticotropin and beta-endorphin
TL;DR: A peptide with high potency and intrinsic activity for stimulating the secretion of corticotropin-like and β-endorphinlike immunoactivities by cultured anterior pituitary cells has been purified in this paper.

A Syndrome produced by Diverse Nocuous Agents
TL;DR: If the organism is severely damaged by acute non-specific nocuous agents such as exposure to cold, surgical injury, production of spinal shock, excessive muscular exercise, or intoxications with sublethal doses of diverse drugs, a typical syndrome appears, the symptoms of which are independent of the nature of the damaging agent or the pharmacological type of the drug employed.

Simultaneous single isotope radioenzymatic assay of plasma norepinephrine, epinephrine and dopamine.
TL;DR: Modification of the original single isotope radioenzymatic assay of Passon and Peuler permits the direct and simultaneous analysis of norepinephrine, epinephrine and dopamine in plasma samples of 50 μl or less.
