On the one hand, this confirms the fact that despite analogous behavioural reactions, corticosterone
responses may vary greatly even between individuals and between breeds ; on the other hand, it has been shown that white-feathered hens are more susceptible to stress than hens with dark feathers [2,12,14,25].
05) relationships were found between the logarithm of fecal corticosterone
concentration and slope, distance to water, fecal N, fecal C, parasite load, date, vehicle traffic on the day of sample collection, vehicle traffic during the week before sample collection, and vehicle traffic during the month before sample collection, or the number of days since deer or bison hunting began or the midpoint of the rutting season.
The serum corticosterone
concentrations are shown in Figure 5; these results indicate significant effects of noise exposure only at 1DPN, which was when serum corticosterone
was significantly elevated in every noise-exposed group compared with the control group.
These markers include hormones such as cortisol and the closely related corticosterone
, both of which correlate with chronic stress, as well as epinephrine (adrenaline) and norepinephrine (noradrenaline), which indicate immediate stress and anxiety.
05) among patients with APAs than BAH, peripheral venous concentrations of corticosterone
, cortisol, DHEA, and DHEA-S were higher (P < 0.
All the rats in the 21-day study were subjected to anxiety test after 21 days of icv colchicine/artificial CSF injection and then serum corticosterone
levels were measured in these rats in the same manner like the 14-day study.
In addition, two studies examined biological mechanisms associated with stress responses of the neuroendocrine system, specifically the effects of corticosterone
administration  and norepinephrine levels  on motor symptom outcomes.
Honey also modulates ACTH and corticosterone
levels following noise stress either by suppressing HPA mobilization in response to stress or by facilitating elevated plasma corticosterone
and ACTH levels back to baseline following the termination of the stress.
Dexamethasone suppression test showed that CUMS produced a significant reduction in the percentage of dexamethasone induced plasma corticosterone
Table 1 shows the effects of chronic administration of nicotine on lipid profile and serum corticosterone
levels in male and female mice.
All core clinical biochemistry and hormonal tests were performed at Royal Hospital, Oman, using Architect 8000c and Architect 2000i, respectively, with Automated Processing System (Abbott, USA); and 17[alpha]-hydroxyprogesterone, renin and aldosterone were performed by ELISA (DRG, USA); while 11-deoxycortisol, 11-deoxycorticosterone, corticosterone
, androstenedione and ACTH were performed at Laboratoroire Cerba (France).
We estimated the concentration of corticosterone
and neopterin (IBL, Germany), total testosterone (DBC, Canada), estradiol (Cusabio, China) and progesterone (DBC, Canada), and TGF-[beta] (eBioscience, Austria) in the serum by ELISA.
