OBJECT The aim of this study was to assess whether aneurysm surgery can be performed in patients with ruptured cerebral aneurysms by using three-dimensional computerized tomography (3D-CT) angiography alone, without conventional catheter angiography. METHODS In a previous study, 60 patients with subarachnoid hemorrhage (SAH) from ruptured aneurysms were… (More)
A case of partial trisomy 17 with partial monosomy X resulting from a maternal X-autosomal translocation t(X;17)(q13;q21) is presented. Three previously reported cases are reviewed and the phenotypic features of trisomy 17 are discussed.
Paroxysmal nocturnal hemoglobinuria is an acquired hematopoietic disease characterized by abnormal blood cell populations in which the biosynthesis of the glycosylphosphatidylinositol (GPI) anchor is deficient. Deficiency of surface expressions of GPI-anchored complement inhibitors leads to complement-mediated hemolysis. Here we report that PIG-A, which… (More)
The site of action of a Vero toxin (VT2 or Shiga-like toxin II) from enterohemorrhagic Escherichia coli and Shiga toxin from Shigella dysenteriae 1 on eukaryotic ribosomes was studied. Treatment of eukaryotic ribosomes with either toxin caused the release of a fragment of 400 nucleotides from 28S ribosomal RNA when the isolated ribosomal RNA was treated… (More)
The recent identification of two mannose-binding lectin-associated serine protease clones from Halocynthia roretzi, an ascidian, suggested the presence of a complement system in urochordates. To elucidate the structure and function of this possibly primitive complement system, we have isolated cDNA clones for ascidian C3 (AsC3) and purified AsC3 protein… (More)
IgM is the first antibody to be produced in a humoral immune response and plays an important role in the primary stages of immunity. Here we describe a mouse Fc receptor, designated Fc alpha/microR, and its human homolog, that bind both IgM and IgA with intermediate or high affinity. Fc alpha/microR is constitutively expressed on the majority of B… (More)
Mannose-binding lectin-associated serine protease (MASP) is a newly identified member of the serine protease superfamily. MASP is involved in host defense against pathogens through a novel system of complement activation, designated the lectin pathway. To elucidate the origin of the lectin pathway and the molecular evolution of MASP, we cloned six MASP… (More)
BACKGROUND AND AIMS Corticotropin releasing hormone (CRH) is a major mediator of the stress response in the brain-gut axis. Irritable bowel syndrome (IBS) is presumed to be a disorder of the brain-gut link associated with an exaggerated response to stress. We hypothesised that peripheral administration of alpha-helical CRH (alphahCRH), a non-selective CRH… (More)
The lectin complement pathway is initiated by binding of mannose-binding lectin (MBL) and MBL-associated serine protease (MASP) to carbohydrates. In the human lectin pathway, MASP-1 and MASP-2 are involved in the proteolysis of C4, C2 and C3. Here we report that the human MBL-MASP complex contains a new 22 kDa protein [small MBL-associated protein (sMAP)]… (More)
Juxtaglomerular cell tumors are rare. This report presents a case of juxtaglomerular cell tumor without hypertension. All previously reported cases showed marked hypertension, whereas this is the first case of juxtaglomerular cell tumor without hypertension. The immunohistochemistry and ultrastructure of this case are discussed.
