A formyl group-ended poly(DL-lactic acid) (PLA-aldehyde), synthesized in the same manner as reported previously, was utilized to produce the polymeric marker for PLA-related nanoparticles. Namely, pyrene-ended poly(DL-lactic acid) (PLA-pyrene) was prepared as a polymeric marker by the reductive
Irinotecan-containing nanoparticles (NP) were prepared by coprecipitation with addition of water to acetone solution of poly(DL-lactic acid), poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) and irinotecan, and subsequent evaporation of organic solvent. NP were purified
The novel nanoparticles (CPT-NP) were prepared by the solvent evaporation method using methoxypolyethylene glycol-poly(DL-lactic acid) block copolymer as a matrix and camptothecin (CPT) as an antitumor agent, and the antitumor characteristics were examined in vitro and in vivo. The mean diameter of
Two bleomycin (BLM)-containing agents (BLM-PLA, BLM-SOL) were prepared, and the drug distribution and antitumor effect were studied. BLM-PLA is an agent in which BLM is incorporated into biodegradable low-molecular-weight polylactic acid, and BLM-SOL is an aqueous solution of BLM. BLM-PLA or BLM-SOL
Purpose: Yttrium-90 (90Y)-polymer composite (radiogel) may be administered directly into cancerous tissues to deliver highly localized beta radiation for therapy. In a dose-escalation study, the authors investigated the feasibility of treating feline and canine soft-tissue sarcomas
Camptothecin (CPT)-loaded nanoparticles were prepared using poly(dl-lactic acid) (PLA) and poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) copolymer (PEG-PPG-PEG), and examined for particle characteristics, in vitro release, pharmacokinetics and efficacy. The
Poly(DL-lactic acid) (PLA)/poly(ethylene glycol)-block-poly (propylene glycol)-block-poly(ethylene glycol) copolymer (PEG-PPG-PEG) nanoparticles loaded with camptothecin (CPT), called CPT-NP, were prepared and examined for particle size change and drug release in phosphate-buffered saline, pH 7.4,
