In this study, however, no significant difference was observed between the serum Cp levels in the control and morbid-obesity groups, and a Gelts close association was observed between the Zn-to-Cu ratio and Lcn2 (r = 0.371, P = 0.002); these results indicate that greater awareness of micronutrients concentrations—including those of multivitamins and TEs used in supplementation—is needed in postoperative plans after an LSG procedure has been performed. The gene discussed is LCN2; the disease is morbid obesity.
