The influence of cytochrome P450 2D6 (CYP2D6) genetic variability was examined in psychiatric inpatients by evaluating adverse drug events (ADEs), hospital stays, and total costs over a 1-year period in an extension of a previously published brief report. One hundred consecutive psychiatric patients from Eastern State Hospital in Lexington, Kentucky, were(More)
The OECD has proposed five principles for validation of QSAR models used for regulatory purposes. Here we present a case study investigating how these principles can be applied to models based on Kohonen and counter propagation neural networks. The study is based on a counter propagation network model that has been built using toxicity data in fish fathead(More)
This work describes the in situ synthesis of oligonucleotide arrays on glass surfaces. These arrays are composed of features defined and separated by differential surface tension (surface tension arrays). Specifically, photolithographic methods were used to create a series of spatially addressable, circular features containing an amino-terminated(More)
The predictive abilities of two-group classification models (CMs) are often expressed in terms of their Cooper statistics. These statistics are often reported without any indication of their uncertainty, making it impossible to judge whether the predicted classifications are significantly better than the predictions made by a different CM, or whether the(More)
Coronary artery rethrombosis can complicate initially effective thrombolytic therapy. Platelets interacting with injured vascular endothelium in a region along the coronary artery with reduced luminal cross-sectional area contribute to rethrombosis. The purpose of this study was to investigate the potential of the F(ab')2 fragment of the murine monoclonal(More)
The acute dermal and ocular effects of chemicals are generally assessed by performing the Draize skin and eye tests, respectively. Because the animal data obtained in these tests are also used for the development and validation of alternative methods for skin and eye irritation, it is important to assess the inherent variability of the animal data, since(More)
The aim of this study was to explore the possibility of distinguishing between eye irritants (I; EU risk phrases R36 and R41) and nonirritants (NI), by using in vitro endpoints of the hen's egg test on the chorioallantoic membrane (the HETCAM test) and the neutral red uptake (NRU) test. Prediction models were derived by applying binary logistic regression(More)
It has become widely accepted that individual genetic variation is a prime determinant in both disease susceptibility and toxic response to therapeutic agents and xenobiotics. Emerging genetic sequence data and phenotype association studies are expected to enable disease risk prediction and guide subsequent therapeutic approaches in individual cases.(More)
