Abstract Objective: Glucocorticoid (GC) treatment suppress the hypothalamic-pituitary-adrenal axis, which may lead to tertiary adrenal insufficiency. This study aimed investigate prevalence of insufficiency among patients with oral lichen planus treated topical GC (clobetasol propionate) in cavity, a standard option for this condition. Methods: In cross-sectional study, we included 24 receiving...

Adrenal hormones, ACTH plasma concentrations and the ultrasonographic evaluation of adrenal glands are considered complementary in clinical evaluations hypothalamic–pituitary–adrenal (HPA) axis function several species. In dogs, age, size weight have a significant effect on glands. neonatal foals, measurements been demonstrated to be reliable; however, individual variables features has not inve...

ABSTRACT As a response to environmental cues, maternal glucocorticoids (GCs) may trigger adaptive developmental plasticity in the physiology and behavior of offspring. In North American red squirrels (Tamiasciurus hudsonicus), mothers exhibit increased GCs when conspecific density is elevated, selection favors more aggressive perhaps active under these conditions. We tested hypothesis that elev...

We reviewed neuromedin U (NMU) and neuromedin S (NMS) involvement in the regulation of the hypothalamo-pituitary-adrenal (HPA) axis function. NMU and NMS are structurally related and highly conserved neuropeptides. They exert biological effects via two GPCR receptors designated as NMUR1 and NMUR2 which show differential expression. NMUR1 is expressed predominantly at the periphery, while NMUR2 ...

OBJECTIVE This study investigated whether baseline cortisol measures predicted future anxiety, and compared cortisol values of groups with different developmental pathways of anxiety. METHOD Cortisol levels were assessed in 1768 individuals (10-12 years). Anxiety levels were assessed at the same age and 2 years later. RESULTS Cortisol measures did not predict future anxiety levels. Individu...

Stereotypic behaviours are common in animals in impoverished housing, arising from two complementary processes: (1) thwarted attempts to perform motivated behaviours; (2) forebrain dysfunction impeding normal behavioural inhibition. When enriched animals are moved to impoverished housing, they are sometimes protected against developing stereotypic behaviour, but in other cases become even more ...

In this issue of the JCI, Aberg and colleagues report that psychological stress disrupts the skin's antimicrobial barrier and increases the severity of cutaneous infections (see the related article beginning on page 3339). This effect is mediated by endogenous glucocorticoids produced secondarily to stress-related activation of the hypothalamic-pituitary-adrenal axis. Thus, this study provides ...

Glucocorticoid (GC) is an adrenal steroid with diverse physiological effects. It undergoes a robust daily oscillation, which has been thought to be driven by the master circadian clock in the suprachiasmatic nucleus of the hypothalamus via the hypothalamus-pituitary-adrenal axis. However, we show that the adrenal gland has its own clock and that the peripheral clockwork is tightly linked to ste...

A narrative review of the major evidence concerning the relationship between emotional regulation and depression was conducted. The literature demonstrates a mediating role of emotional regulation in the development of depression and physical illness. Literature suggests in fact that the employment of adaptive emotional regulation strategies (e.g., reappraisal) causes a reduction of stress-elic...
