Docking and scoring is currently one of the tools used for hit finding and hit-to-lead optimization when structural information about the target is known. Docking scores have been found useful for optimizing ligand binding to reproduce experimentally observed binding modes. The question is, can docking and scoring be used reliably for hit-to-lead(More)
Predictive models for drug safety are crucial for helping to avoid costly late-stage failures. We review recent work on models for genotoxicity, liver toxicity, CYP450 inhibition and cardiotoxicity. These models have improved somewhat in recent years, and research has expanded into new frontiers, such as the prediction of liver toxicity. However, much more(More)
Serum antibodies to the capsular polysaccharide (CPS) ~ of Neisseria meningiti-dis, as well as to other encapsulated bacterial pathogens, confer immunity to invasive diseases caused by these organisms (1-6). There is an age-related development of meningococcus group A (GrA) CPS antibodies (1, 2, 4-6). During infancy and childhood, when placentaily required(More)
Very large data sets of molecules screened against a broad range of targets have become available due to the advent of combinatorial chemistry. This information has led to the realization that ADME (absorption, distribution, metabolism, and excretion) and toxicity issues are important to consider prior to library synthesis. Furthermore, these large data(More)
This paper examines the fit of three different statistical distributions to the returns of the S&P 500 Index from 1950-2005. The normal distribution is a poor fit to the daily percentage returns of the S&P 500. The lognormal distribution is a poor fit to single period continuously compounded returns for the S&P 500, which means that future prices are not(More)
CONTEXT Low back injuries are a common occurrence in athletes and often result in missed competition and practice time. The examination of athletes with low back pain commonly involves diagnostic imaging, which rarely guides the clinician in selecting the appropriate interventions. DATA ACQUISITION All years of PubMed, CINAHL, PEDro, and SPORTDiscus were(More)
We read with interest the article on body mass index (BMI) as an indicator of obesity among athletic adolescents, which appeared in the May/June 2011 issue of Sports Health. 2 While fully appreciative of the authors' extensive research and in support of the general message of their manuscript (ie, skinfold measurements provide a superior estimate of body(More)
