The choice of cortisol sampling times in early childhood studies varies widely. Given that recommendations on protocols are largely based adults, the present study aimed to broaden current knowledge by examining how reliably measures obtained at different daytimes would reveal between-individual differences toddlers’ levels. Parents were instructed take 10 saliva samples consecutively (five per...

Markers of HPA axis function, including diurnal cortisol rhythm and cortisol responses to stress or pharmacological manipulation, are increasingly reported as disrupted in schizophrenia (SZ) and bipolar disorder (BD). However, there has been no direct comparison of cortisol responses to stress in SZ and BD in the same study, and associations between cortisol dysfunction and illness characterist...

PURPOSE Central fat distribution is significantly associated with an increased cortisol levels. We hypothesized that men with metabolic syndrome have a higher serum cortisol levels compared to women. The purpose of this study was to compare serum cortisol levels, and its correlation with serum leptin levels, between men and women with and without metabolic syndrome. METHODS A cross sectional ...

Cortisol coregulation, which is the up- or down-regulation of partners' physiological stress responses, has been described for individuals with strong attachment bonds, e.g. parents and their children, and romantic relationship partners. Research into moderating effects on cortisol coregulation suggests stronger covariation among distressed partners. Whether cortisol coregulation is unique to h...

The relationship between self-reported traumatic childhood experiences, cortisol levels, aggression, and psychopathy was investigated in prison inmates (n=47) and healthy controls (n=27). Besides questionnaires, a brief salivary diurnal profile was measured. Results show that criminals (both psychopaths and non-psychopaths) demonstrate more traumatic childhood experiences than the control group...

PURPOSE: To compare salivary and serum cortisol levels, salivary alpha-amylase (sAA), and unstimulated whole saliva (UWS) flow rate in pregnant and non-pregnant women. METHOD: A longitudinal study was conducted at a health promotion center of a university hospital. Nine pregnant and 12 non-pregnant women participated in the study. Serum and UWS were collected and analyzed every trimester and tw...

Fisheries Department, Faculty of Natural Resources, University of Guilan, Sowmeh Sara,1144, Iran ABSTRACT This study was conducted the effect of stress on blood glucose and cortisol levels in cultured great sturgeon. Blood sampling was done and then water level decreased to the half in experimental tanks. The fish were exposed in that situation and second blood sampling was taken after ...

We have previously shown that dog-owner interaction results in increasing oxytocin levels in owners and dogs, decreasing cortisol levels in owners but increasing cortisol levels in dogs. The present study aimed to further investigate whether oxytocin and cortisol levels in the previously tested owners and dogs were associated with their behaviors during the interaction experiment. Ten female vo...
