Advertisement SELECT was designed to determine whether semaglutide can exert protective cardiovascular effects in patients with overweight or obesity in the absence of diabetes
For this purpose, we used T1w (available in FSL) and magnetic resonance angiography (MRA) maps [42] in the MNI space with 2-mm isotropic resolution to extract anatomical ROIs for the pituitary gland and the nearby internal carotid arteries
For the quantification of sulfur metabolites in the tissue samples, the tissue metabolites were extracted and derivatized with NEM in ice-cold extraction solvent (80% MeOH: 20% H 2 O containing 25 mM NEM and 10 mM ammonium formate, pH=7.0) which includes stable isotope labeled internal standards (20 M [ 13 C 3 , 15 N]-cysteine-NEM, 36.4 M [ 13 C 2 , 15 N]-GSH-NEM, 10 M [D 4 ]-Cystine, 0.92 M [ 13 C 5 , 15 N 2 ]-GSSG, 20 M [D 4 ]-Hypotaurine, and 20 M of [ 13 C 2 ]-Taurine at a final concentration of 50 mg/mL followed by incubation on 4 C for 24 hr
The margin for error is significant, especially at lower doses where small volume differences translate to large percentage changes in the delivered dose
