Reinforced Polymer–Nanoparticle Hydrogels for Subcutaneous and Sustained Delivery of Trastuzumab
Advanced Healthcare Materials, EarlyView.Biologic therapy development is rapidly accelerating, requiring extended delivery formulation strategies. Supramolecular hydrogels and electrostatic complexation create subcutaneous depots that release clinically relevant trastuzumab doses in a controlled manner through simple component mixing without chemical modifications.

The development of human sera tests for HDL-bound serum PON1 and its lipolactonase activitys⃞
Journal of Lipid Research, 2007 Serum paraoxonase (PON1) is a lipolactonase that associates with HDL-apolipoprotein A-I (HDL-apoA-I) and thereby plays a role in the prevention of atherosclerosis. Current sera tests make use of promiscuous substrates and provide no indications regarding
