AIMS Neurogenesis in adult humans occurs in at least two areas of the brain, the subventricular zone of the telencephalon and the subgranular layer of the dentate gyrus in the hippocampal formation. We studied dentate gyrus subgranular layer neurogenesis in patients subjected to tailored antero-mesial temporal resection including amygdalohippocampectomy due(More)
Hepatocyte growth factor (HGF) is a mesenchymal derived growth factor known to induce proliferation and "scattering" of epithelial and endothelial cells. Its receptor is the tyrosine kinase encoded by the c-MET protooncogene. Here we show that highly purified recombinant HGF stimulates hemopoietic progenitors to form colonies in vitro. In the presence of(More)
Diamond-Blackfan anemia (DBA) is an inherited pure red blood cell aplasia that often requires lifelong transfusional support. The origin of the imperfect erythrogenesis is not known. The existence of more than one molecular basis for DBA is indicated by its different modes of inheritance and widely variable clinical phenotypes. Several erythroid growth(More)
The aim of this study was to evaluate the effect of stem cell factor (SCF) on the in vitro growth of bone marrow hematopoietic progenitors from patients with acquired severe aplastic anemia (AA) or Fanconi's anemia (FA). For this purpose, we studied 11 patients with acquired AA (5 at diagnosis, 6 after ALG treatment), 12 patients with FA, and nine normal(More)
We describe a system for computer-assisted writing of legal documents via a question-based mechanism. This system relies upon an underlying ontological structure meant to represent the data flow from the user's input, and a corresponding resolution algorithm, implemented within a local engine based on a Last-State Next-State model, for navigating the(More)
