The synthesis, characterization and inclusion in liposomes of a glucosylated bolaamphiphile built on a calix[4]arene scaffold are described. The new glucocalixarene bolaamphiphile destabilizes bilayers of saturated lipids whereas it rigidifies those of unsaturated lipids, thus reducing leakage of calcein from the liposome internal aqueous compartment. Moreover, from fluorescence and turbidimetr...

The aggregation of insulin is complicated by the coexistence of various multimers, especially in the presence of Zn(2+). Most investigations of insulin multimerization tend to overlook aggregation kinetics, while studies of insulin aggregation generally pay little attention to multimerization. A clear understanding of the starting multimer state of insulin is necessary for the elucidation of it...

A multicenter study conducted in healthy population of 6 cities from the 4 corners and central China for 7 serum-specific proteins to identify the sources of variation and establish the reference intervals on 2 automation platforms.A total of 3148 subjects aged 19 to 64 years old were enrolled in this study to ensure at least 120 participants in each 10-year age group and each city. The majorit...

The effect of heparin on both native and denatured protein aggregation was investigated by turbidimetry and dynamic light scattering (DLS). Turbidimetric data show that heparin is capable of inhibiting and reversing the native aggregation of bovine serum albumin (BSA), β-lactoglobulin (BLG), and Zn-insulin at a pH near pI and at low ionic strength I; however, the results vary with regard to the...
