Anti-glomerular Basement Membrane Disease After Diagnosis of Immunoglobulin A Nephropathy: A Case Report.

Anti-glomerular basement membrane (anti-GBM) disease has one of the worst prognoses of nephritis and is rarely associated with other forms of glomerulonephritis. In this report, we present the case of a 76-year-old man who developed anti-GBM disease four months after being diagnosed with IgA nephropathy (IgAN). To our knowledge, although there have been several reports of IgAN combined with anti-GBM disease, there have been no cases in which we were able to confirm that the anti-GBM antibody titer changed from negative to positive over the disease course.

Myocardin-related transcription factor contributes to renal fibrosis through the regulation of extracellular microenvironment surrounding fibroblasts.

Fibroblast accumulation and extracellular matrix (ECM) deposition are common critical steps for the progression of organ fibrosis, but the precise molecular mechanisms remain to be fully investigated. We have previously demonstrated that lysophosphatidic acid contributes to organ fibrosis through the production of connective tissue growth factor (CTGF) via actin cytoskeleton-dependent signaling, myocardin-related transcription factor family (MRTF) consisting of MRTF-A and MRTF-B-serum response factor (SRF) pathway. In this study, we investigated the role of the MRTF-SRF pathway in the development of renal fibrosis, focusing on the regulation of ECM-focal adhesions (FA) in renal fibroblasts.

Membranous Nephropathy-Like Apolipoprotein E Deposition Disease with Apolipoprotein E Toyonaka and Homozygous Apolipoprotein E2/2 without Dyslipidemia, with Characteristic Electron-Dense Deposits.

Recently, several cases of novel apolipoprotein E (apoE)-related glomerular disease known as membranous nephropathy (MN)-like apoE deposition disease with apoE Toyonaka (Ser197Cys) and homozygous apoE2/2 have been reported. However, the clinical and pathological characteristics are uncertain due to the small number of reports. Here, we report an additional case with various clinical and pathological characteristics.

Feasibility of the automated column agglutination technique for titration of anti-A/B antibodies in ABO-incompatible living kidney transplantation.

Introduction: Quantitative measurement of anti-A/-B antibody titers is important during ABO-incompatible living kidney transplantation (ABOi-LKT).

Methods: We conducted a multi-institutional study to measure the antibody titers using the automated column agglutination technique (auto-CAT) and tube test (TT) method in ABOi-LKT recipients. Statistical analysis was performed to evaluate the two methods.

Anti-Fy-mediated delayed hemolytic transfusion reaction following emergency-release red blood cell transfusion: possible involvement of HLA-DRB1*04:03 in the Japanese population.

A 43-year-old Japanese male, who had undergone open liver surgery for tumor resection, presented with decreased hemoglobin levels on Day 13 post-emergency-release transfusion of 16 units of Fy(a +) red blood cells. As the anemia was accompanied by increased lactate dehydrogenase, indirect bilirubin, and reticulocytes, as well as decreased haptoglobin, it was attributed to hemolysis. In the diagnostic workup for hemolytic reaction, the direct antiglobulin test result for IgG was positive and the antibody dissociated from the patient's peripheral red blood cells was identified as anti-Fy (titer, 4).

Prolonged incubation period of hepatitis B in a recipient of a nucleic acid amplification test-negative hepatitis B virus window donation.

Background: The occurrence of transfusion-transmitted hepatitis B virus (HBV) infection has fallen dramatically due to continuous improvements in pre-transfusion laboratory testing. However, the characteristics of transfusion-transmitted HBV infection caused by individual donor nucleic acid amplification test (ID-NAT)-negative blood products are unclear.

Case Presentation: A 76-year-old woman with acute myeloid leukemia was diagnosed with transfusion-transmitted HBV infection after receiving apheresis platelets derived from an ID-NAT-negative blood donation.

Comparison of the tube test and column agglutination techniques for anti-A/-B antibody titration in healthy individuals.

Background And Objectives: Determination of the anti-A/-B titre pre- and post-transplantation is beneficial for treatment selection. Currently, the recommended method for antibody titration is the tube test (TT) assay. Dithiothreitol (DTT) is used for IgM antibody inactivation.

Grasping state estimation of printable soft gripper using electro-conductive yarn.

Automatic handling of many types of food materials are required to realize the automation of production of commercially prepared box lunches. A printable soft gripper was developed for food handling which is simple to produce with a 3D printer. However, the sensing ability of the printable soft gripper was not discussed in previous research.

Low-grade myofibroblastic sarcoma of the palm.

We report here a case of an unusual spindle cell tumour of the palm with myofibroblastic differentiation, which was surgically excised. Histologically and immunohistochemically, it was a low-grade myofibroblastic sarcoma. After 25 months follow-up the patient is well and free of recurrence.

Radius lengthening for the treatment of Bayne and Klug type II and type III radial longitudinal deficiency.

Purpose: We performed radius lengthening to treat radial deviation of the wrist in patients with Bayne and Klug type II and type III radial longitudinal deficiencies. The purpose of this investigation was to review our results of radius lengthening for radial longitudinal deficiency.

Methods: Beginning in 1991 radius lengthening was performed to treat 4 patients with radial longitudinal deficiency whose mean age at the initial lengthening was 16 months.

Anterior interosseous nerve palsy after reduction and percutaneous pinning of open fractures of the radius and ulna.

We report a case of an anterior interosseous nerve palsy after closed reduction and percutaneous pinning of open fractures of the radius and ulna in an adult. Operative findings showed that the anterior interosseous nerve was trapped between the distal and proximal part of the fractured radius. Treatment by neurorrhaphy gave a satisfactory result.

Bone lengthening for congenital differences of the hands and digits in children.

Purpose: We investigated the growth of bones after lengthening to evaluate the effectiveness and usefulness of bone lengthening in congenital hand deficiencies.

Methods: Bone lengthening was performed to treat congenital hand deficiencies including hypoplastic thumb, hypoplasia of the small finger, cleft hand, metacarpal synostosis, brachymetacarpia, symbrachydactyly, and amniotic band syndrome. A total of 15 patients (1-13 years old) underwent lengthening of 23 bones.
