This study retrospectively characterized population-based pharmacokinetic parameters for gentamicin in neonates and young infants, and evaluated the predictive performance of these parameters in a Bayesian forecasting program. Population parameter...

The region of human chromosome 19 which includes the myotonic dystrophy locus (DM) has recently been redefined by the tight linkage between it and the gene for muscle-specific creatine kinase (CKMM), whichlies just proximal to DM.

Purpose: Molecular mechanisms by which balloon angioplasty injury-induced neointimal hyperplasia can be reduced by intravascular brachytherapy are unclear. We investigated the role of nuclear factor-kappaB (NF-B-K) in neointimal hyperplasia follow...
