C-peptide, a key biomarker for beta-cell function in diabetes, has potential understanding and managing the disease, though its application type 2 diabetes is limited by insufficient evidence. It provides insights into endogenous insulin secretion faces challenges measurement standardization. In 1 C-peptide levels reflect beta cell loss, while higher indicate risk of progression. Preserved diff...

Objective(s): Polyethylenimine (PEI) is one of the most widely used polymers in gene delivery. The aim of this study was to modify PEI by replacing some of its primary amines with Brevinin 2R (BR-2R) peptide in order to increase the efficiency of gene delivery.Materials and Methods: Polyethylenimine was modified by BR-2R peptide by two d...
