Calibration standards were prepared by spiking 50 L of human plasma with appropriate amount of thiols to obtain the following concentrations: 20, 40, 60, 100, 200, 300, 600 nmol/mL plasma for Cys, 2, 4, 6, 10, 20, 30, 60 nmol/mL for Hcy, GSH and 0.1, 0.5, 1.0, 2.0, 4.0, 5.0, 10.0 nmol/mL for N-Hcy-Lys
Unlike MC4R-targeted agonists such as setmelanotide, whose efficacy is intrinsically limited by the functional status of the impaired receptor, GLP-1 RAs operate via pathways largely independent of the leptin-melanocortin circuitry
In contrast, participants in the control group exhibited deterioration in several inflammatory and clinical parameters, including a significant increase in CRP levels, and STAT3 and DAS28 scores
