In this paper, the effect of chitosan molecular weight on the characteristics (size, encapsulation efficiency, zeta potential, surface morphology and release rate) of vitamin C encapsulated tripolyphosphate cross-linked chitosan (TPP-chitosan) microspheres. The molecular weight of chitosan had a noticeable influence on the size, encapsulation efficiency, zeta potential, surface morphology and c...

This paper describes the synthesis, structural characterization and cellular uptake of a supramolecular 1 : 2 inclusion complex of meso-tetraphenylporphyrin having an octaarginine peptide chain (R8-TPP) and heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (TMe-β-CD). R8-TPP was synthesized by 2 approaches: (1) on-resin conjugation of the N-terminal of octaarginine with 5-(4-carboxyphenyl)-10,15,20-t...

This article summarizes the key points of a technology and telecommunications infrastructure assessment conducted by the University of Hawai'i Telecommunications and Information Policy Group (TIPG) in partnership with the Pacific Association for Clinical Training (PACT). It includes an overview of telecommunications infrastructure and services in the U.S.-Affiliated Pacific Islands (USAPI) juri...

Introduction At the request of the Northwest Power and Conservation Council and the Pacific Northwest Aquatic Monitoring Partnership (PNAMP), the ISAB reviewed the design and proposed statistical analyses in a study comparing stream habitat monitoring protocols, which will be carried out by PNAMP. The study objectives are as follows:
