NF-kappa B-induced gene expression contributes significantly to the pathogenesis of inflammatory diseases such as arthritis. I kappa B kinase (IKK) is the converging point for the activation of NF-kappa B by a broad spectrum of inflammatory agonists and is thus a novel target for therapeutic intervention. We describe a small molecule, selective inhibitor of(More)
MOTIVATION Prediction of ligand binding sites of proteins is significant as it can provide insight into biological functions and reaction mechanisms of proteins. It is also a prerequisite for protein-ligand docking and an important step in structure-based drug design. RESULTS We present a new algorithm, Roll, implemented in a program named POCASA, which(More)
PURPOSE Determine the failure patterns of oral cavity squamous cell carcinoma (SCC) treated with intensity-modulated radiotherapy (IMRT). METHODS AND MATERIALS Between May 2001 and July 2005, 55 patients with oral cavity SCC were treated with IMRT for curative intent. Forty-nine received postoperative IMRT, 5 definitive IMRT, and 1 neoadjuvant. Three(More)
Interleukin-8 (IL-8/CXCL8) is a chemokine that increases endothelial permeability during early stages of angiogenesis. However, the mechanisms involved in IL-8/CXCL8-induced permeability are poorly understood. Here, we show that permeability induced by this chemokine requires the activation of vascular endothelial growth factor receptor-2 (VEGFR2/fetal(More)
PURPOSE To review the University of Iowa experience with intensity-modulated radiotherapy (IMRT) in the treatment of head-and-neck squamous cell carcinoma. METHODS AND MATERIALS From October 1999 to April 2004, 151 patients with head-and-neck squamous cell carcinoma were treated with IMRT for curative intent. One patient was lost to follow-up 2 months(More)
BACKGROUND There is overwhelming evidence that dietary supplementation with n-3 polyunsaturated fatty acids (PUFAs), mainly EPA (C20:5n-3) and DHA (C22:6n-3), has cardiovascular protective effects on patients with type 2 diabetes mellitus (T2DM) but not on healthy people. Because the T2DM heart increases fatty acid oxidation (FAO) to compensate for the(More)
PURPOSE To determine the accuracy and prognostic significance of post-treatment [(18)F]-fluorodeoxyglucose positron emission tomography (FDG-PET) in head-and-neck squamous cell carcinoma after radiotherapy (RT). METHODS AND MATERIALS This was a retrospective study of 188 patients with head-and-neck squamous cell carcinoma who had undergone FDG-PET within(More)
PURPOSE The role of neck dissection after definitive radiation for head-and-neck cancer is controversial. We select patients for neck dissection based on postradiation therapy (post-RT), computed tomography (CT), and [18F] fluorodeoxyglucose positron emission tomography (FDG PET). We summarize the clinical outcomes of patients treated with this policy to(More)
By stimulating the migration and proliferation of endothelial cells (ECs), vascular endothelial growth factor (VEGF) is a potent angiogenic factor. However, the molecular mechanism involved in the VEGF-induced angiogenesis remains elusive. We hypothesized that sterol regulatory element binding proteins (SREBPs), transcription factors governing cellular(More)
Influenza A virus (IAV) is one of the most common infectious pathogens in humans. Since the IVA genome does not have the processing protease for the viral hemagglutinin (HA) envelope glycoprotein precursors, entry of this virus into cells and infectious organ tropism of IAV are primarily determined by host cellular trypsin-type HA processing proteases.(More)
