A formal framework of knowledge to support rational psychoactive drug selection.

Rational psychoactive drug selection is a data and knowledge intensive task which requires true expertise from clinical, pathophysiological and pharmacotherapeutic knowledge. This paper presents a framework of knowledge, which relates concepts from several disciplines required for psychoactive drug selection in a formal way. A framework, when based on formal semantics, avoids ambiguity and gives conceptual clarity and supports precise use of terminology which is required when many domain experts (clinicians, pharmacologists and basic science researchers) are involved.

Towards a more rational use of psychoactive substances in clinical practice.

Complex knowledge and data intensive nature of the psychoactive drug selection and prescription process often makes for irrational and inconsistent use of psychoactive drugs in clinical practice. After describing the state of the art with respect to psychoactive drug prescription practices and selection processes, our aim is to analyze the advantages of computer support systems in assisting the clinician in his clinical decisions. Finally, we will review the neuropsychiatric expert systems developed for the neuropsychiatric domain.

Sandimmune to Neoral conversion and value of abbreviated AUC monitoring in stable pediatric kidney transplant recipients.

Neoral is a new microemulsion formulation of cyclosporin A (CsA) that has been reported to have better absorption characteristics than sandimmune. We converted 25 long-term pediatric renal transplant recipients with a mean age of 14.1 yr and a mean follow-up period of 6.

Use of the methylxanthine derivative A802715 in transplantation immunology: II. In vivo experiments.

Background: We have previously demonstrated in vitro that the methylxanthine derivative A802715 suppresses the cyclosporine (CsA)-resistant "signal two"-dependent pathway of T cell activation and hence acts synergistically with CsA. Here, this synergism was further investigated in vivo in rats.

Methods: Primary cardiac allografts were placed in the neck, and secondary grafts were transplanted intra-abdominally.
