A novel role of the dihydroorotatedehydrogenase (DHODH) inhibitor leflunomide as a potential anti-melanoma therapy was recently reported (Nature 471: 518-22, 2011). We previously reported that leflunomide strongly activates the transcriptional activity of the Aryl Hydrocarbon Receptor (AhR). We therefore tested whether the AhR regulates the anti-proliferative effects of leflunomide in...
The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that plays multiple roles in regulation of immune and inflammatory responses. The ability of certain AhR ligands to induce regulatory T cells (Tregs) has generated interest in developing AhR ligands for therapeutic treatment of immune-mediated diseases. To this end, we...

Non-coding ribonucleic acid (ncRNA) is of interest for its diverse roles in cell and viral biology. RNA molecules vary greatly in terms of size, structure, and function. In recent years, the modification of existing RNA structures has been used for biochemical methods of enormous impact including CRISPR and RNAi methods....
Premature birth interrupts the typical development of the human fetus, leaving the infant born with underdeveloped gastrointestinal and immune systems. Preterm infants have reduced stomach acidity, reduced digestive protease activity, more permeable intestinal membranes, impaired innate and adaptive immune response, and poor microbiome development. Due to these factors, preterm infants...
This paper is part of an effort to examine the application of discontinuous Galerkin (DG) methods to the numerical modeling of the general circulation of the ocean. One step performed here is to develop an integral weak formulation of the lateral pressure forcing that is suitable for usage with a...
This paper addresses some issues involving the application of discontinuous Galerkin (DG) methods to ocean circulation models having a generalized vertical coordinate. These issues include the following. (1) Determine the pressure forcing at cell edges, where the dependent variables can be discontinuous. In principle, this could be accomplished by solving...
