introduction: ghrelin is a potent orexigenic agent in rodents and humans. some studies have shown that ghrelin participates in the adaptive response to weight loss and plasma concentration of ghrelin rises with dieting. on the other hand, weight loss and fasting is accompanied by increased levels of epinephrine and cortisol. in this study, we investigated the effects of epinephrine and cortisol...

In liver cirrhosis with bacterial infection, hepatoadrenal syndrome has been described recently as a progressive impairment in the adrenocortical reserve, with deficient production or action of glucocorticoids resulting in adrenal insufficiency. The aim of this study was to explore the characteristics of cortisol in hepatitis B virus (HBV) cirrhosis patients in the absence of bacterial infectio...

Rationale: Exogenous cortisol is a modulator of behavior related to increased motivated decision making (Putman et al., 2010), where risky choices yield potentially big reward. Making risk based judgments has been shown to be important to athletes in optimizing pacing during endurance events (Renfree et al., 2014; Micklewright et al., 2015). Objectives: Therefore, the aims of this study were to...

The study assessed the correlation between cortisol (COR) levels and concurrent infection for the patients with hepatitis B cirrhosis for corresponding countermeasure analysis. In total, 86 patients with hepatitis B cirrhosis (non-infection group) and 32 patients with hepatitis B cirrhosis complicated with infection (infection group) who were diagnosed and treated in the Beijing YouAn Hospital ...

Reboxetine is a selective noradrenaline reuptake inhibitor, whereas mirtazapine acts as an antagonist at noradrenergic ·2, serotonin (5-HT2), 5-HT3 and histamine H1 receptors. In a former study we could demonstrate an inhibitory impact of mirtazapine on cortisol secretion. In the present investigation, the influence of combined administration of 15 mg mirtazapine and 4 mg reboxetine on the cort...

The world tilapia production faces seasonal variations. However, very few nutritional studies have addressed suboptimal temperature. We evaluated the effect of two temperatures (20 or 30 °C) and vegetable oil blends (one rich in corn ( COR ) one linseed LIN )) on growth, body composition, blood parameters using a 2 × factorial design with following treatments: COR-20; LIN-20; COR-30; LIN-30 Tri...

Although hyperglycemia at admission with colic has been reported to have a poor prognosis, there is no report specifically about acute colitis with systemic inflammatory response syndrome (SIRS) in horses. In this study, we measured blood glucose (Glu), insulin (Ins), and cortisol (Cor) levels in 17 Thoroughbred racehorses diagnosed as having acute colitis with SIRS, and examined the relationsh...

To the Editor: The concentration of cortisol in the saliva reflects the activity of the hy-pothalamic-pituitary-adrenal axis (1), and an increased late-night salivary cortisol has Ͼ95% sensitivity and spec-ificity for Cushing syndrome (1, 2). We compared a commonly used modification of a RIA for serum cor-tisol with a new enzyme immunoas-say (EIA) specifically designed to measure salivary corti...

In this single-blind study, the effects of acute oral administration of high-dose Hypericum perforatum extract WS 5570 on the cortisol (COR), adrenocorticotropic hormone (ACTH), growth hormone (GH), and prolactin (PRL) secretions were examined in 12 healthy male volunteers. In a randomized order, the subjects received placebo or WS 5570 at several dosages (600, 900, and 1,200 mg) at 08.00 h on ...
