BACKGROUND AND PURPOSE Despite the widespread use of angioplasty, adjunct chemical therapy is often needed to treat patients with cerebral vasospasm. In this study, we examined the safety of intraarterial administration of verapamil to patients with cerebral vasospasm. We herein summarize our 2-year experience with this treatment. METHODS We(More)
This paper adopts various data envelopment analysis (DEA) approaches to investigate the technical efficiency and service effectiveness for some selected 76 railways (DMUs) in the world during the period 1999-2001. We estimate technical efficiency by the input-oriented DEA models and service effectiveness by the output-oriented DEA models. The technical(More)
Input congestion very likely existed in rail transport. However, early works measuring the rail transport efficiencies rarely took the input congestion into account; hence, the proposed strategies for enhancing efficiencies can be misleading. This study revisited the rail transport efficiencies with consideration of input congestion. We employed data(More)
An automated data processing pipeline, designed for handling a large throughput of sequentially acquired MRI brain data, is described. The system takes as input multiple diffusion weighted (DWI) and perfusion weighted imaging (PWI) volumes acquired at different temporal points, automatically segments and registers them, and ultimately outputs a database(More)
In the light of occasional involvement of traffic accidents and of seldom costless to dispose such undesirable accidents, conventional data envelopment analysis (DEA) methods, which assume that traffic accidents are freely disposable in bus transit efficiency measurement, may not be appropriate. To rectify this shortcoming, this paper attempts to construct(More)
The choice of an animal model for cerebrovascular research is often determined by the disease subtype to be studied (e.g. ischemic stroke, hemorrhage, trauma), as well as the nature of the intervention to be tested (i.e. medical device or pharmaceutical). Many initial studies are performed in smaller animals, as they are cost-effective and their encephalic(More)
Consistent high-quality of papers published in “Chemico-Biological Interactions” can only be maintained with the co-operation and dedication of a number of expert referees. The Editors would like to thank all those who have donated the hours necessary to review, evaluate and comment onmanuscripts; their conscientious efforts have enabled the journal to(More)
