OBJECTIVE To assess the arrangement of myocardial bridges. DESIGN A necropsy study of 90 consecutive hearts (56 male, 34 female). RESULTS Myocardial bridges, either single or multiple, were seen in 50 (55.6%) of the 90 hearts. The left anterior descending artery was the most commonly affected artery. Thirty five of the 50 hearts which contained in total(More)
Our objective in this study was to determine possible associations between antiphospholipid antibodies (aPL) and histologically defined heart valve lesions in the MRL-lpr/lpr mouse, a suitable model for the antiphospholipid syndrome (APS). At monthly intervals, from 2 to 6 months of age, three MRL-lpr/lpr mice (two with anticardiolipin antibodies, one(More)
Differentiation between Marfan's disease, or its forme fruste counterpart and Erdheim's cystic medionecrosis can be made in cases of aortic dilatation or dissection. This study examined the morphological features at light microscopy of aortic tissue, removed at surgery in 10 patients with Marfan's disease. A separate group consisted of 24 patients who did(More)
The blastic transformation in vitro of peripheral blood lymphocytes was measured by the 72-hour uptake of tritiated thymidine ((3)H-6-thymidine) in 23 patients with mucosal ulcerative colitis, three patients with acute Crohn's colitis with rectal involvement, and seven normal subjects. The 23 patients with ulcerative colitis were subdivided into three(More)
CD25 is expressed at high levels on regulatory T (Treg) cells and was initially proposed as a target for cancer immunotherapy. However, anti-CD25 antibodies have displayed limited activity against established tumors. We demonstrated that CD25 expression is largely restricted to tumor-infiltrating Treg cells in mice and humans. While existing anti-CD25(More)
The early detection of relapse following primary surgery for non-small-cell lung cancer and the characterization of emerging subclones, which seed metastatic sites, might offer new therapeutic approaches for limiting tumour recurrence. The ability to track the evolutionary dynamics of early-stage lung cancer non-invasively in circulating tumour DNA (ctDNA)(More)
BACKGROUND Among patients with non-small-cell lung cancer (NSCLC), data on intratumor heterogeneity and cancer genome evolution have been limited to small retrospective cohorts. We wanted to prospectively investigate intratumor heterogeneity in relation to clinical outcome and to determine the clonal nature of driver events and evolutionary processes in(More)
