Ezrin is a cytoskeleton linker protein that is actively involved in the metastatic process of cancer cells. We have searched for a prognostic value of ezrin and some of its partners: α-smooth muscle actin and CD44H in 37 patients with an osteosarcoma. Automate immunohistochemistry (IHC) with anti-ezrin, α-smooth muscle actin and CD44H antibodies was(More)
OBJECTIVE This is a retrospective study of 18 patients harboring a solitary fibrous tumor of the central nervous system. Therapeutic management and outcome were analyzed. METHODS Between 1999 and 2004, 18 patients harboring central nervous system solitary fibrous tumors were surgically treated at our two institutions. There were nine men and nine women.(More)
BACKGROUND Pilocytic astrocytomas (PAs) are characterized by an excellent prognosis although several factors of adverse outcome have been reported. The mitogen-activated protein kinase pathway plays a major role in their tumorigenesis. AIM To report a series of 148 PAs in children to define clinicopathological and biological prognostic factors. METHODS(More)
In contrast to pilocytic astrocytomas (WHO grade I gliomas) that are circumscribed and cured by surgical resection, invasion is a hallmark of grades II–IV gliomas. Proteases play a major role in the invasion process and correlations between glioma grading, survival and protease expression have been demonstrated. In this study, we have chosen to study using(More)
Virus-prokaryote interactions were investigated in four natural sites in Senegal (West Africa) covering a salinity gradient ranging from brackish (10‰) to near salt saturation (360‰). Both the viral and the prokaryote communities exhibited remarkable differences in their physiological, ecological and morphological traits along the gradient. Above 240‰(More)
Low-grade osteosarcoma is a rare malignancy that may be subdivided into two main subgroups on the basis of location in relation to the bone cortex, that is, parosteal osteosarcoma and low-grade central osteosarcoma. Their histological appearance is quite similar and characterized by spindle cell stroma with low-to-moderate cellularity and(More)
Meningeal solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) are distinct entities in the World Health Organization (WHO) classification of central nervous system (CNS) tumors while they belong to the same spectrum of tumors in other locations. Well-defined histological prognostic factors are also lacking for these tumors. In order to clarify the(More)
To assess the prognostic value of histological classification for renal outcome, we did a multivariate analysis of 194 patients with immunoglobulin A (IgA) nephropathy between 1985 and 1995. We also evaluated semiquantitative scales of tubular lesions and vessel lesions. At the time of the biopsy, 65 patients (33.5%) had chronic renal failure. At the end of(More)
Gliomas are the most frequent tumors of the central nervous system. The WHO classification, based on the presumed cell origin, distinguishes astrocytic, oligodendrocytic and mixed gliomas. A grading system is based on the presence of the following criteria: increased cellular density, nuclear atypias, mitosis, vascular proliferation and necrosis. The main(More)
The reduction of E-cadherin expression, which is involved in the initial step of invasion and metastasis of cancer, was investigated in 218 human breast carcinomas. Quantitative immunohistochemical assays (ICAs) were performed on frozen sections. Quantitation was assessed by processing digitized microscopic images of immunoreactions using a computerized(More)
