OBJECTIVES:A primary defect of the tight junctions and, hence, increased intestinal epithelial permeability has been proposed as a basic pathogenic event in Crohn's disease. Challenge of the mucosal immune system by the commensal gut flora would then result in chronic inflammation. Alternatively, increased permeability could be the result of inflammation.(More)
Bevacizumab (Avastin) is a humanized monoclonal antibody that inhibits the activity of vascular endothelial growth factor (VEGF), a key molecule controlling tumour blood vessel formation (angiogenesis). By inhibiting VEGF and thus tumour angiogenesis, bevacizumab inhibits tumour growth and survival. In patients with metastatic colorectal cancer (CRC),(More)
Introduction of microbial trehalose biosynthesis enzymes has been reported to enhance abiotic stress resistance in plants but also resulted in undesirable traits. Here, we present an approach for engineering drought stress tolerance by modifying the endogenous trehalase activity in Arabidopsis (Arabidopsis thaliana). AtTRE1 encodes the Arabidopsis(More)
OBJECTIVES:Etanercept, an injectable tumor necrosis factor (TNF) receptor fusion protein, binds and inactivates human TNF and is used in active rheumatoid arthritis. Blocking TNF with monoclonal antibodies has also been beneficial in Crohn's disease. We attempted to determine the efficacy and safety of etanercept for induction of clinical, endoscopic, and(More)
