These protocols cover both intranasal and subcutaneous administration routes
Handling and Stability Risks Improper handling exposure to light, heat, repeated freeze-thaw cycles, or strongly alkaline conditions can degrade the peptide or disrupt copper coordination, producing experimental variability that is sometimes mistaken for biological inconsistency
To detect potential sources of heterogeneity, subgroup analyses were performed according to the predefined variables, including duration of the intervention, NAC dosage, study location and the type of control
Anti-Inflammatory and Antioxidant Effects: Investigate suppression of pro-inflammatory cytokines (e.g., IL-6, TNF-) and enhancement of superoxide dismutase (SOD) and other antioxidant pathways
Some peptides may take time
