Dendrimer diffusion in kappa-carrageenan gel structures.

The effect of the kappa-carrageenan concentration on gel microstructure and self-diffusion of polyamideamine dendrimers has been determined by transmission electron microscopy (TEM), image analysis, and nuclear magnetic resonance (NMR) diffusometry. Different salt conditions of KCl, NaCl, and mixtures thereof allowed for formation of significantly different microstructures. The kappa-carrageenan concentrations were varied between 0.

[Human serum insulin-binding component in health and in type 1 diabetes mellitus].

Serum-affine components have been detected in the sera of healthy donors and patients with diabetes mellitus. Human serum has been ascertained to contain insulin-binding component. The latter has not been shown to be immunoglobulin, i.
