abstract：:Microencapsulation of ketoprofen using Eudragit RS and RL (acrylic resins) was investigated based on the dispersion system of ketoprofen-containing acetone in liquid paraffin. Aluminium tristearate was used as an additive for the preparation of microcapsules. Good reproducibility was observed in the microencapsulation...

abstract：:The sorption of 5-fluorouracil from aqueous solutions onto poly(methyl methacrylate) was investigated. Linear sorption isotherms were obtained and no crystallinity of the nanoparticles after sorption was detectable by X-ray analysis indicating a partitioning of the drug into the polymer particles-forming a solid solut...

abstract：:Bacampicillin hydrochloride has been microencapsulated to mask its very bitter taste. The objective of the study was to compare the in vitro release and bioavailability of bacampicillin hydrochloride from microcapsules coated with two principally different polymers: a water-insoluble polymer, ethylcellulose, and an ac...

abstract：:The development of microparticulate food particles for marine suspension-feeders is discussed with respect to the difficulties of nutrient delivery in the aquatic environment and to feeding and digestion in crustacea and bivalve molluscs. Loss of nutrients from particles suspended in seawater must be minimized by eith...

abstract：:Since 1978 we have prepared microencapsulated insecticides by complex coacervation and interfacial polymerization for household insect pest control, fenthion being the main core element. A series of tests have been conducted against mosquitoes (Culex pipiens quinquefasciatus), cockroaches (Periplaneta americana) and b...

abstract：:The degradation of polybutylcyanoacrylate (PBC) and polyhexylcyanoacrylate (PHC) nanoparticles, together with their association with and toxicity towards isolated hepatocytes, were determined. Nanoparticles were not taken up by rat hepatocytes at a significant level. The LD50S of PBC and PHC nanoparticles towards hepa...

abstract：:H-n.m.r. spectroscopy of small unilamellar phospholipid vesicles in the presence of the lanthanide probe ion Dy3+ has been used to study the permeability of these liposomes induced by the bile salts (glycocholate and glycodeoxycholate) and pancreatic phospholipase A2. A marked synergism is demonstrated in the combined...
