OBJECTIVES We evaluated the bioavailability of Cd in 86 components of 57 jewelry items found to contain high levels of Cd (> 10,000 ppm) by X-ray fluorescence (XRF), using extractions that simulate mouthing or swallowing of jewelry items. METHODS We screened jewelry for Cd content by XRF. Bioavailability was measured in two ways. Items were placed in(More)
Chronic lymphocytic leukemia (CLL) is an incurable disease identified most commonly in elderly patients. Interphase cytogenetics, IGHV status and ZAP70 protein expression/ methylation have been used to risk-stratify patients relative to likelihood of disease progression or treatment assignment when CLL becomes symptomatic Reviewed in 1. microRNAs are short(More)
In mixture toxicity, concentration-effect data are often used to generate conclusions on combined effect. While models of combined effect are available for such assessments, proper fitting of the data is critical to obtaining accurate conclusions. In this study an asymmetry parameter (s) was evaluated for data-fitting and compared with our previous(More)
