The AKT2 gene is one of the human homologues of v-akt, the transduced oncogene of the AKT8 virus, which induces lymphomas in mice. In previous studies, AKT2, which codes for a serine-threonine protein kinase, was shown to be amplified and overexpressed in some human ovarian carcinoma cell lines and amplified in primary tumors of the ovary. To confirm and(More)
The possibility of generating neural stem/precursor cells (NPCs) from induced pluripotent stem cells (iPSCs) has opened a new avenue of research that might nurture bench-to-bedside translation of cell transplantation protocols in central nervous system myelin disorders. Here we show that mouse iPSC-derived NPCs (miPSC-NPCs)-when intrathecally transplanted(More)
Endothelin-1 (ET-1) is a peptide classically produced by endothelial cells and known for its powerful vasoconstrictor activity. However, recent data suggest an involvement of ET-1 also in reproductive function. This study was designed to examine the possible presence and role of ET-1 in human luteal cells. Purified luteal cells were incubated for different(More)
PURPOSE OF REVIEW Transplantation of neural stem/precursor cells (NPCs) has been proposed as a promising therapeutic strategy in almost all neurological disorders characterized by the failure of central nervous system (CNS) endogenous repair mechanisms in restoring the tissue damage and rescuing the lost function. Nevertheless, recent evidence consistently(More)
OBJECTIVE The aim of this prospective study is to assess the time lapse between the onset of recurring headache and the correct diagnosis in a cohort of pediatric patients attending an Italian children's headache center for the first time. METHODS One hundred and one patients and parents, referred to the Pediatric Headache Centre of San Raffaele Hospital(More)
BACKGROUND Antibodies against aquaporin-4 (AQP4), a water channel particularly expressed on perivascular astrocytic podocytes, are proposed as a marker for the diagnosis of neuromyelitis optica (NMO). However, a consensus on seroprevalence and optimal detection method has not yet been reached. OBJECTIVES To investigate the performance of different assays(More)
OBJECTIVE To examine the possible effect of growth hormone-releasing hormone (GHRH), vasoactive intestinal peptide, and pituitary adenylate cyclase-activating peptide on basal and hCG-stimulated P production by human luteal cells. DESIGN Cultures of human luteal cells from the early and midluteal phase. SETTING All corpora lutea were obtained from the(More)
Migraine patients with multiple brain white matter hyperintensities (WMHs) may represent a diagnostic challenge. Using double inversion recovery (DIR) imaging, we studied whether cortical lesions (CLs) could be seen in these patients. Approval of the institutional review boards and written informed consent were obtained from each participant. CLs and WM(More)
PROBLEM Several recent data suggest an involvement of endothelin (ET)-1, a powerful vasoconstrictor peptide, in reproductive function. This study was designed to investigate the presence and role of ET-1 in human corpus luteum. METHOD OF STUDY Purified luteal cells were incubated for different times with ET-1 or ET-3 alone or associated with human(More)
