For instance, it has been shown that after an experimental psychologic stress, the evoked cortisol response in fatigued breast cancer survivors is much smaller than that in nonfatigued ones, pointing to the involvement of the HPA axis in cancer-related fatigue (286)
This pentadecapeptide demonstrates resistance to degradation in gastric juice, a property that distinguishes it from many therapeutic peptides that require modified administration routes to avoid gastric inactivation
