To establish further a practical quantitative in chemico reactivity assay for screening contact allergens, lysine peptide was incorporated into a liquid chromatography and tandem mass spectrometry-based assay for reactivity assessments of hapten and pre-/pro-hapten chemical sensitizers. Loss of peptide was determined following 24 h coincubation with test(More)
This study investigated the factor structure and psychometric properties of the Pain Anxiety Symptoms Scale (PASS). The PASS assesses four components of pain-related anxiety: cognitive, fear, escape/avoidance, and physiological. Confirmatory factor analyses provided support for both the one-factor and the four-factor structures reported for samples of(More)
This study included revision and systematic examination of the factor structure and psychometric properties of the Cognition Checklist. Two separate samples of college undergraduates participated. Analysis showed that all the models reported previously in the literature fitted the data poorly for Sample 1 (n = 220). Principal components and maximum(More)
1. To develop a framework for exposure calculation via the dermal route to meet the needs of 21st century toxicity testing and refine current approaches; 2. To demonstrate the impact of exposure scenario and application conditions on the plasma concentration following dermal exposure. A workflow connecting a dynamic skin penetration model with a generic(More)
The Pain Behavior Check List (PBCL) was designed to assess the frequency of four dimensions of pain behavior: distorted ambulation, affective distress, facial/audible expressions, and seeking help. This study evaluated theoretical factor structure, internal consistency, and construct validity of the PBCL in a nonclinical college sample. Results provided(More)
This study examined the effect of math history lessons (which focused on the accomplishments of Latin American, African, African-American, and Middle Eastern individuals) on the attitudes of fifteen students enrolled in an Algebra 2 class at a predominantly African-American high school. Qualitative data taken during interviews with the participants showed(More)
