In order to decrease inter- and intra-observer variability in delineating OARs relevant for neuro-oncology and thus derive consistent dosimetric data, we propose this atlas to be used in photon and particle therapy. The atlas is available online at www.cancerdata.org and will be updated whenever required.
Objective. To determine the occurrence of antineutrophil cytoplasmic antibodies (ANCA) and the specificity of these antibodies (Ab) in serum from patients with rheumatoid arthritis (RA) and patients with rheumatoid arthritis complicated by vasculitis (rheumatoid vasculitis [RV]).Methods. ANCA was detected with an indirect immunofluorescence test on ethanol-fixed granulocytes. Ab against the cytoplasmic antigens proteinase-3, elastase, lactoferrin (LF), and myeloperoxidase were measured by enzyme-linked immunosorbent assay.Results. ANCA were found in the serum of 43% of 49 patients with RV and in 36% of 50 patients with RA. Anti-LF Ab occurred more frequently in RV patients (45%) than in RA patients (4%), whereas reactivity against the other cytoplasmic antigens did not differ significantly between these groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
