    Notes: The infinite dimensional highest weight representations of Uqosp(1|2) for the deformation parameter q being a root of unity are investigated. As in the cases of q-deformed nongraded Lie algebras, we find that every irreducible representation is isomorphic to the tensor product of a highest weight representation of sl2(R) and a finite dimensional one of Uqosp(1|2). The structure is investigated in detail. © 1997 American Institute of Physics.

    Notes: Superconducting MgB2 thin films were prepared on Al2O3(0001) and MgO(100) substrates. Boron thin films were deposited by the electron-beam evaporation followed by postannealing process with magnesium. Proper postannealing conditions were investigated to grow good superconducting MgB2 thin films. The x-ray diffraction patterns showed randomly oriented growth of MgB2 phase in our thin films. The surface morphology was examined by scanning electron microscope and atomic force microscope. Critical current density (JC) measured by transport method was about 107 A/cm2 at 15 K, and superconducting transition temperature (TC) was ∼39 K in the MgB2 thin films on Al2O3. © 2001 American Institute of Physics.

    Megakaryothrombopoiesis During Ex Vivo Expansion of Human Cord Blood CD34+ Cells Using Thrombopoietin (2002)

    Notes: Thrombopoietin (TPO) is one of the most promising stimulants for ex vivo expansion of haematopoietic stem cells. Previously, we have found that TPO induces a characteristic pattern of apoptosis during ex vivo expansion of human cord blood (CB) CD34+ cells and that the TPO-induced apoptotic cells belong to megakaryocyte (MK) lineage. In this study, we have examined the maturation of MK and platelet production in association with the TPO-induced apoptosis. CD34+ cells, purified from human CB, were expanded in serum-free conditions stimulated with TPO. Apoptosis was confirmed by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labelling (TUNEL) assay and electron microscopy (EM). Simultaneous measurement of DNA content and immunophenotyping revealed that the cells with higher DNA content (〉8 N) constituted less than 5% of the CD41+ fractions until day 14, implying premature apoptosis of MKs before full polyploidization. Nevertheless, EM observation showed not only platelet territories but also newly produced platelets in which granules and microfilaments could be identified. Furthermore, flow cytometry demonstrated that the platelet fraction expressed P-selectin and an activation motif on GPIIb/IIIa recognized by monoclonal antibody PAC-1 upon stimulation with adenosine diphosphate (ADP). In addition, periodic acid-Schiff (PAS)-positive materials and nonspecific esterase activities could be demonstrated. Therefore, it is suggested that platelet production and the accompanying processes, rather than apoptosis only, be hastened during the ex vivo expansion of CB CD34+ cells when using TPO.

    Notes: Anti-Golgi autoantibodies (AGAs) and their targets have been reported from several diseases. However, the association of AGAs, selective autoantigens and related clinical diseases is still obscure. In this study, the presence of AGAs in the sera of 5983 patients was screened to explore the association of AGAs and clinical diseases. By means of indirect immunofluorescence using HEp-2 cells, sera of 12 patients bearing AGAs were identified. The location of recognized Golgi autoantigen(s) was confirmed by the treatment of monensin and double immunostaining using β-COP. Using the immunoelectron microscopy, AGA immunoreactivity was clearly demonstrated at a stack structure, characteristic of the Golgi complex. Furthermore, analysis of the 12 AGA-positive sera by Western blot revealed at least 15 components of Golgi antigens with relative molecular weights ranging from 54 to 350 kDa, and several Golgi autoantigens identified may be novel. Notably, over half of the AGA-positive cases found belong to non-autoimmune diseases, particularly hepatic disorder. This study presents the association of AGAs, components of the Golgi complex and clinical diseases.

    Notes: Oyster mushrooms, Pleurotus sajor-caju, were grown on chopped corn stover substrate with increasing amounts of cracked corn supplementation and were harvested at immature and mature stages of growth. Descriptive terms for mushroom color, texture, and flavor were generated and used to determine the impact of cracked corn supplementation on the sensory attributes of fresh and stored (5C for 48h) immature mushrooms and of fresh mature oyster mushrooms. Results indicated that supplementation with cracked corn significantly (P 〈 0.05) affected the texture attributes, i.e., tough, rubbery, and fibrous of the oyster mushroom. When factor analysis (FA) was applied to the descriptor data, three factors were identified in the immature fresh and immature stored oyster mushrooms data which explained 86 and 82%, respectively, of the variation. FA of data from the mature oyster mushrooms identified 3 factors which explained 89% of the data variation.

    Immunohistochemical study of arginase in cancer of the stomach (1996)

    Notes: Abstract High levels of arginase have been detected in gastric adenocarcinoma. To examine the hypothesis that this is due to macrophage infiltration into the tumour, we localized the cellular distribution of arginase by immunohistochemical staining. We examined gastric adenocarcinomas and their corresponding normal tissues (n=45), leiomyomas (n=2), leiomyosarcomas (n=3), human gastric adenocarcinoma cell lines (n=3), and benign gastric ulcers (n=4) by the avidin-biotin-peroxidase complex technique. Macrophages with strong arginase immunoreactivity were observed infiltrating both gastric normal and cancer tissues. No arginase immunoreactivity was observed in normal mucosal gland, muscular and serosal tissues or benign gastric ulcers. The immunoreactivity of arginase was positive but heterogeneous in most specimens of gastric adenocarcinoma (62.2%) and was absent from gastric intestinal metaplasia, leiomyomas and leiomyosarcomas. Among the 28 neoplasms with arginase immunoreactivity, scattered immunoreactivity was also noted in adjacent dysplastic glands in 12 (42.8%) specimens. Arginase immunoreactivity was observed in all three gastric cancer cell lines. Arginase is present in the cytoplasm but not in the nucleus. These data suggest that the high arginase levels in adenocarcinoma cancer tissues originate largely from cancer cells.

    Notes: Abstract  We investigated the expression of Ki-67 antigen using monoclonal antibody MIB-1 in glomeruli and renal tubules of 21 children (18 males, 3 females) with post-streptococcal glomerulonephritis (PSGN). Patients were divided into two groups of active and convalescent phases. The active group (n=13) comprised those patients with clinical manifestations of the acute nephritic syndrome consisting of edema, hypertension, hematuria, and oliguria or those in whom percutaneous renal biopsy was performed within 4 weeks of onset of the symptoms of PSGN and those with serum C3 levels below 55 mg/dl at the time of biopsy. MIB-1 expression was considered positive when staining of endocapillary cells was observed. Of the 21 biopsies, expression of MIB-1 in glomeruli and renal tubules was observed in 14 cases (63.6%) and 20 cases (95.7%), respectively. The expression of MIB-1 in glomeruli of patients with active disease (11/13, 84.6%) was significantly higher than that of the convalescent group (2/8, 25%) (P=0.018). The cellularity in the glomeruli was more severe in the active group than the convalescent group (P=0.0475). There was a significant difference of neutrophilic infiltration in glomeruli between the active group and the convalescent group (P=0.0117). However, glomerular MIB-1 expression did not correlate with the degree of immunofluorescence, the number of neutrophils in the glomeruli on light microscopy, and the presence of subepithelial dense deposits on electron microscopy. There was no significant correlation between MIB-1 and serum C3 level. There was no significant correlation between glomerular MIB-1 expression and creatinine clearance (r=–0.180, P=0.556) or 24-h urinary protein excretion (r=0.434, P=0.137). Our results suggest that the expression of MIB-1 in glomeruli in the active phase in PSGN was higher than in the convalescent phase and expression of glomerular MIB-1 appears to be related to glomerular endocapillary proliferation with exudative lesions in children with PSGN.

    Notes: This time, we would like to report our recent study on Pb(ZrTi)O3(PZT)-basedferroelectrics, currently one of interesting topics in condensed matter science. In this study, a newmethod, called synchrotron X-ray microdiffraction (XRMD) in situ, was introduced to examine theelectric field-induced structural modulation of the epitaxially grown tetragonal PZT thin film. Toevaluate the d-spacing (d001) from the measured intensity contour in the two theta-chi space, the peakposition in each diffraction profile was determined by applying the two-dimensional Lorentzianfitting. By tracing the change of d-spacing as a function of the applied electric field and by examiningthe Landau free energy function for P4mm symmetry, we were able to estimate the two importantparameters that characterize the field-induced structural modulation. Further theoretical analysisshows that the compressive epitaxial in-plane stress dominantly contributes to the elongation of thec-axis lattice constant in the c-axis oriented epitaxial PZT film
