Transport of L-[3H]carnitine and acetyl-L-[3H]carnitine at the blood-brain barrier (BBB) was examined by using in vivo and in vitro models. In vivo brain uptake of acetyl-L-[3H]carnitine, determined by a rat brain perfusion technique, was decreased in the presence of unlabeled acetyl-L-carnitine and in the absence of sodium ions.

Purpose Rho kinase (ROCK) pathways control fundamental cell functions, making ROCK an important therapeutic target in several pathophysiologic conditions. The purpose of this study was to investigate whether inhibition of ROCK can suppress apoptosis of the corneal endothelium and to determine the role of ROCK signaling in regulating apoptosis.
