The ventriculus terminalis (VT) is a small ependyma-lined cavity within the conus medullaris that is in direct continuity with the central canal of the anterior portion of the spinal cord. Normally, such a cavity is identifiable only histologically in children and adults and can be visualized using common neuroradiological techniques only after dilation.(More)
The mammalian growth factor erv1-like (GFER) gene encodes a sulfhydryl oxidase enzyme, named Augmenter of Liver Regeneration (ALR). Recently it has been demonstrated that ALR supports cell proliferation acting as an anti-apoptotic factor. This effect is determined by ALR ability to support the anti-apoptotic gene expression and to preserve cellular normoxic(More)
An increase in mitochondrial DNA (mtDNA) content and mitochondrial biogenesis associated with the activation of PGC-1α signalling pathway was previously reported in type I endometrial cancer. The aim of this study has been to evaluate if mtDNA content and the citrate synthase (CS) activity, an enzyme marker of mitochondrial mass, increase in progression(More)
BACKGROUND Neuroendocrine tumors (NETs) metastasize to the bone. However, the incidence, clinical features, management and pathogenesis of bone involvement in NET patients have been poorly investigated. METHODS We reviewed all published reports of histologically confirmed bone metastatic NETs and explored clinical, radiological, prognostic and therapeutic(More)
Little is known about the immunoediting process in precancerous lesions. We explored this aspect of benign colorectal adenomas with a descriptive analysis of the immune pathways and immune cells whose regulation is linked to the morphology and size of these lesions. Two series of polypoid and nonpolypoid colorectal adenomas were used in this study: 1) 84(More)
Ewing sarcoma-primitive neuroectodermal tumors (ES/PNETs) constitute a family of neoplasms characterized by a continuum of neuroectodermal differentiations. ES/PNET of the uterus is rare. There are 48 cases of ES/PNET of the uterus published in the literature as far as we know. We describe a case of Ewing sarcoma of the uterus occurring in a 17-year-old(More)
Giant cell angiitis of the CNS is an uncommon form of vasculitis. Neurological manifestations, both of the peripheral and CNS, are common. The most frequent manifestations are visual loss and stroke. Hemorrhagic onset is uncommon. Most cases have a fatal outcome and a tissue diagnosis is rarely established in life. We describe an unusual case of giant cell(More)
