Abstract:
:Uncertainty in exposure assessment and uncertainty in kinetic models of early effects after exposure to a toxin are addressed in this paper. Sources of uncertainty in the determination of exposure of workers in chemical industry exposed to dioxins are exhibited and a simple kinetic model for biomonitor measurements of the concentrations from occupational exposure is derived. Model uncertainty, and uncertainty in the model parameters of physiologically-based pharmacokinetic models (PBPK models) are addressed when these models are used to estimate the effective dose in risk assessment. Uncertainty in the model parameters originating from the use of different statistical analysis methods is exhibited for Hill type nonlinear kinetics of enzyme induction mediated by a toxin.

杂志文章abstract::We review the effects of two transcription factor decoy oligonucleotides on apoptosis of human osteoclasts (OCs). The first decoy molecule was designed to inhibit nuclear factor kappa-B (NF-kappaB) binding to target sequence, the second to increase estrogen receptor (ER) alpha expression. We found that both decoy mole...
