Insulin (Ins) spontaneously and easily complexed with the hydrogel nanoparticle of hydrophobized cholesterol-bearing pullulan (CHP) in water. The complexed nanoparticles (diameter 20-30 nm) thus obtained formed a very stable colloid. The thermal denaturation and subsequent aggregation of Ins were effectively suppressed upon complexation. The complexed Ins(More)
Two months after the 2010 Haiti Earthquake, a reconnaissance team from the University of Notre Dame traveled to Léogâne with a follow up trip in August 2010. The team sought to determine the failure modes for residential housing in the area and survey the structural systems, construction materials, building practices, and non-engineering constraints that(More)
The modification of human insulin by the covalent attachment of monosaccharide moieties to insulin amino group(s) alters the aggregation and self-association behavior, improving both the pharmaceutical stability and biological response. The synthesis of p-succinamidophenyl glucopyranoside-insulin conjugate(s) (SAPG-insulin) has resulted in seven possible(More)
Treatment of diabetes mellitus by insulin injections provides long-term control of the disease but lacks any feedback response to glucose concentration changes, which finally leads to a number of life-threatening conditions. The purpose of this study was to improve and optimize an implantable, concanavalin A (Con A) based, glucose-responsive insulin(More)
Biomer/poly(N-isopropylacrylamide)/[poly(NiPAAm)] thermosensitive polymer blends were prepared and their application as heparin-releasing polymer coatings for the prevention of surface-induced thrombosis was examined. The advantage of using poly (NiPAAm)-based coatings as heparin-releasing polymers is based on the unique temperature-dependent swelling of(More)
A method of achieving dimensionality reduction is presented. The reduced dimensionality is achieved by utilizing a least squared error technique under the assumption that the goodness criterion is the maximum separation of classes. The criterion is met by first maximizing the spread of the cluster centers, and then minimizing the within class scatter. The(More)
The biochemical and pharmacological properties of bioactive peptides and proteins can be altered by conjugation with polymers. This report describes site-specific attachment of insulin to activated carboxyl groups of carboxymethyl dextran (CMD, MW=51000) through the GlyA1 insulin amino group. On average, three or four insulin molecules were grafted to a CMD(More)
