The immunocytochemical detection of Tie-2/Tek, CD105, and CD31 was assessed in a large series (n = 905) of breast carcinomas on frozen sections. Results were correlated with patients' long-term outcome (median, 11.7 years) to define the respective prognostic significance of these markers. Univariate (Kaplan-Meier) analysis demonstrated that higher(More)
Micrometric lipid compartmentation at the plasma membrane is disputed. Using live confocal imaging, we found that three unrelated fluorescent sphingomyelin (SM) analogs spontaneously clustered at the outer leaflet into micrometric domains, contrasting with homogeneous labelling by DiIC18 and TMA-DPH. In erythrocytes, these domains were round, randomly(More)
Shaken baby syndrome, a rotational acceleration injury, is most common between 3 and 6 months of age and causes death in about 10 to 40% of cases and permanent neurological abnormalities in survivors. We developed a mouse model of shaken baby syndrome to investigate the pathophysiological mechanisms underlying the brain damage. Eight-day-old mouse pups were(More)
Our purpose was to determine the respective prognostic significance of CD105 and CD31 immunoexpression in node negative patients with breast carcinoma, since angiogenesis induces blood borne metastases and death in carcinomas. CD105 (endoglin) has been reported as expressed by activated endothelial cells and consequently should better reflect(More)
OBJECTIVES The aim of this study was to investigate the prognostic value of vascular endothelial growth factor (VEGF) receptors, VEGFR-1 (Flt-1) and VEGFR-2 (KDR/Flk-1) in breast carcinoma. METHODS VEGF receptor expression was investigated using immunohistochemical assays with monoclonal antibodies on frozen sections in a series of 918 patients and was(More)
PURPOSE The aim of the study was to evaluate CD31 and CD105 immunohistochemical expressions in tissue microarrays from 360 breast carcinomas. STUDY DESIGN Computerized (ACIS/Chromavision) assisted image analysis was performed to compare immunoreactions in tissue microarrays with those in current paraffin and frozen sections. We also aimed to determine the(More)
We undertook a multicenter randomized trial to compare the efficacy of terlipressin combined with transdermal nitroglycerin and that of octreotide in the emergency control of acute variceal hemorrhage in cirrhosis. Over 16 mo, 87 patients with endoscopically proved active bleeding from esophageal or cardiac varices were enrolled in five centers in France(More)
Quantitative immunocytochemical assays of 1,200 breast carcinomas were assessed after construction of tissue microarrays. A total of 42 markers were evaluated for prognostic significance by univariate log rank test (mean follow-up, 79 months), using quantitative scoring by an image analysis device and specific software. Complete data were obtained for 924(More)
We aimed in this study at identifying prognostic immunohistochemical molecular signatures indicative of disease outcome, also relevant for development of new specific therapies, in triple-negative (ER, PR, c-erbB2- negative) breast carcinoma subtypes. We evaluated 42 markers in tissue micro-arrays from a series of 924 breast carcinomas including 184(More)
The aim of this study was to identify a prognostic immunohistochemical signature indicative of risk of early metastasis in node-negative breast carcinomas that would also be relevant to the development of new tailored therapy. Quantitative measurements of the immunohistochemical expression of 64 markers (selected from literature data) using high-throughput(More)
