This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...
Radiation therapy treatment planning and optimization requires accurate, precise,
and fast computation of absorbed dose to all critical and target volumes in a patient. A
new method for speeding up the computational costs of Monte Carlo dose calculations is
described that employs a hybrid classical-quantum computing architecture.
Representative results are...
Sickle cell disease (SCD) is a phenotypically variable disorder of hemoglobin that leads to abnormally shaped and dysfunctional red blood cells. Several studies have attempted to construct early predictive models for SCD, including Miller et al.’s (2000) model which uses easily identifiable predictors in early life. The primary aim of...

The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...
