Preparation and in vitro evaluation of a novel chitosan-based hydrogel for injectable delivery of enrofloxacin
BACKGROUND: The development of injectable sustained-release products are of great interest to veterinary pharmaceuticals and animal health business. Recently, great attention has been paid to in situ gel-forming chitosan/beta-glycerophosphate (chitosan/β-GP) solutions due to their good biodegradability and thermosensitivity. OBJECTIVES: The general aim of this study was to prepare a novel in si...

متن کاملFermentation, biodegradation and tensile strength of poly(3-hydroxybutyrate- co-4-hydroxybutyrate) synthesized by Delftia acidovorans
This study discusses poly(3-hydroxybutyrate-co-4-hydroxybutyrate) that is produced by Delftia acidovorans bacteria in fed-batch cultures from various carbon sources. The experimentally determined optimal fed-batch culture conditions are as follows: pH: 7.0, incubation temperature: 26 8C, incubation time: 72 h, and concentration of carbon source: 10 g/L. The maximum 4HB unit composition of P(3HB...
متن کاملInvestigation of Swelling Behavior and Mechanical Properties of a pH-Sensitive Superporous Hydrogel Composite
The objective of the present study is to develop and investigate the swelling behavior of pH-sensitive Superporous Hydrogel (SPH) and SPH composite (SPHC). A novel superporous hydrogel containing poly (methacrylic acid-co-acrylamide) was synthesized from methacrylic acid and acrylamide through the aqueous solution polymerization, using N,N-methylenebisacrylamide as a crosslinker and ammonium...
