Purpose: Statins are widely used in combination with omega-3 fatty acids for the treatment of patients with dyslipidemia. The aim of this study was to compare the pharmacokinetic (PK) profiles of atorvastatin and omega-3-acid ethyl esters between fixed-dose combination (FDC) and loose combination in healthy subjects.
Methods: A randomized, open-label, single-dose, 2-sequence, 2-treatment, 4-period replicated crossover study was performed.
Objective: Eperisone hydrochloride is used in the treatment of musculoskeletal disorders as a muscle relaxant via blocking of calcium channels. In this study, we aimed to investigate the within-subject variability (CV) of reference eperisone formulation for highly-variable drugs and to perform bioequivalence study of two oral formulations (sugar- and film-coated tablets) of eperisone hydrochloride 50 mg in healthy subjects by reference-replicated crossover study.
Materials And Methods: 36 healthy Korean male subjects were recruited, and 33 subjects completed the study.
The purpose of this study was to synthesize biocompatible poly(2-hydroxyethyl aspartamide)-C16-iron oxide (PHEA-C16-iron oxide) nanoparticles and to evaluate their efficacy as a contrast agent for magnetic resonance imaging of lymph nodes. The PHEA-C16-iron oxide nanoparticles were synthesized by coprecipitation method. The core size of the PHEA-C16-iron oxide nanoparticles was about 5 to 7 nm, and the overall size of the nanoparticles was around 20, 60, and 150 nm in aqueous solution.

Materials And Methods: The isotopes [(14)C] and [(59)Fe] were used to label the polymer backbone (CLS) and iron oxide core (FLS), respectively. In addition, unradiolabeled cold superparamagnetic iron oxide nanoparticles (SPION/ULS) were synthesized to characterize particle size by dynamic light scattering, morphology by transmission electron microscopy, and in vivo magnetic resonance imaging (MRI).
