INTRODUCTION |
Cortisol awakening response (CAR) is a rapid increase of cortisol levels within 30-45 min after awakening. |
OBJECTIVE |
This study evaluates CAR compared with cortisol circadian rhythm in active and in remission Cushing's disease (CD). |
MATERIALS AND METHODS |
We evaluated healthy controls (HC, n=19), obese (OB, n=10), in remission (n=08), and active CD patients (n=10). Salivary free cortisol (SF) was determined at 0800, 1100, 1700, 2000, and 2300 h on the first day. CAR was obtained the next morning immediately upon awakening and at 15, 30, 45, and 60-min post-wake up. |
RESULTS |
We observed differences in SF levels throughout the day in HC, OB, and in remission CD (ANOVA P=0.0001) but not in active CD (P=0.2). We demonstrated SF increment after awakening in HC, OB, and in remission CD (ANOVA P=0.007), with no effect of time on SF in active CD. The relative increment of SF obtained at the peak ... |
CONCLUSION |
This study originally described a blunted CAR in active CD in contrast to its presence in HC, OB, and in remission CD. This subtle dysfunction of the hypothalamus-pituitary-adrenal axis may represent a distinct and additional physiopathological phenomenon superimposing the dysregulated cortisol circadian rhythm in this... |

In this research Particle Swarm Optimization (PSO) algorithm is employed to solve mixed- variable nonlinear problems. PSO is an efficient me... |
Abstract As the cost of financial information dissemination continues to decline, investors, firms, and regulators are gradually adopting the principle of fair disclosure, which requires no preferential public disclosure. We use a simple model to examine the impact of this change on information acquisition with two alt... |
In part I of this paper we introduced what we called «relevance structures». In the present part we describe the logic RMI which corresponds to these structures, proving it to be sound and strongly complete relative to them. The language of RMI is similar to that of the systems of Anderson and Belnap, but unlike them i... |
Stillborn calves of a large dairy cattle herd were used for investigations of trace element (Fe, Zn, Cu, Mn) content of the liver and heart muscle. Trace element content varied markedly in the liver and in the heart muscle too but in the heart muscle with a smaller degree. Calves from heifers had a greater trace elemen... |

Foxp3+ T regulatory cells are required to prevent autoimmune disease, but also prevent clearance of some chronic infections. While natural T regulatory cells are produced in the thymus, TGF‐β1 signaling combined with T‐cell receptor signaling induces the expression of Foxp3 in CD4+ T cells in the periphery. We found th... |
