Pharmacokinetic model analysis of interaction between phenytoin and capecitabine.

Objective: Recent reports have shbown an increase in serum phenytoin levels resulting in phenytoin toxicity after initiation of luoropyrimidine chemotherapy. To prevent phenytoin intoxication, phenytoin dosage must be adjusted. We sought to develop a pharmacokinetic model of the interaction between phenytoin and capecitabine.

A Study on Drug Interaction between Warfarin and Capecitabine with Special Reference to the Co-Administered Term or the Discontinuation Term of Capecitabine.

We used the prothrombin time international normalized ratio(PT-INR)to investigate the change in degree and term of warfarin following co-administration and after discontinuation of capecitabine. In this study, approximately 3 years of medical records of 7 patients receiving co-administration therapy of warfarin and capecitabine were obtained from 4 hospitals. We observed daily increases in PT-INR values up to peak PT-INR levels following co-administration of warfarin and capecitabine.

Expression of the mammalian homologue of vacuolar protein sorting 16 (Vps16p) in the mouse and rat brain.

Synaptic vesicle fusion events are essential for synaptic transmission. Membrane docking and fusion events are highly regulated processes requiring the participation of a large number of soluble N-ethylmaleimide-sensitive factors (SNAREs) and SNARE-interacting proteins. We report the neuronal expression of mammalian homologue of vacuolar protein sorting 16 (mVps16p) which exhibits a high homology to the yeast Vps16p, a component of Class C Vps.

Identification of mouse Vps16 and biochemical characterization of mammalian class C Vps complex.

Many multiprotein complexes mediate the fusion of the intracellular membranes. The question how the specificity of the membrane fusion is controlled has not been fully elucidated. Here we report the identification of a mouse homologue Vps16p (mVps16), which exhibits a high homology to the yeast Vps16p, a component of Class C vacuolar protein sorting (Vps) complex implicated in the yeast vacuole membrane fusion.
