Renal Transplantation in Relation to Positive T-cell Flow Cytometric Crossmatch: A Retrospective Study.

Background: Human leukocyte antigen antibodies play a significant role in kidney transplant rejection at all stages. Cross-matching and human leukocyte antigen antibody testing, especially in donor-specific antibody (DSA)-positive cases, are essential for reducing the risk of antibody-mediated rejection. Despite increasing numbers of DSA-positive transplants with desensitization therapy, guidelines for assessing transplant suitability and therapy selection remain undefined.

Tacrolimus-Associated Leukoencephalopathy Following a Living Donor Kidney Transplant for Autosomal Recessive Alport Syndrome: A Case Report.

A 20-year-old male patient diagnosed with chronic renal failure owing to autosomal recessive Alport syndrome underwent kidney transplant, with his mother as the donor. After transplant, the patient's renal function was enhanced; however, owing to preoperative nonadherence, he required sedation and mechanical ventilation. Sedation and mechanical ventilation were discontinued on postoperative day 5.

A case of mucormycosis caused by Rhizopus microsporus in a renal transplant patient.

A 54-year-old man who had been on the kidney donor register for 32 years received a kidney from a 9-year-old boy who had died of fulminant myocarditis. The post-operative course was poor, and hemodialysis was still needed after surgery. A kidney biopsy one hour after surgery showed a neutrophil-predominant inflammatory cell infiltrate localized to the peritubular capillaries (PTC) and acute tubular necrosis of the proximal tubule.

Treatment of emphysematous polycystic renal infection in patients with autosomal dominant polycystic kidney disease: Feasibility and limitations of percutaneous cyst drainage.

Emphysematous polycystic renal infection (EPRI) has a poor prognosis with conservative management, and early surgical nephrectomy has been recommended. However, percutaneous cyst drainage may be a possible treatment option. We experienced 6 patients with autosomal dominant polycystic kidney disease (ADPKD) presenting with EPRI.

BK Virus Nephropathy After Kidney Transplantation and Its Diagnosis Using Urinary Micro RNA.

BK virus-associated nephritis (BKVAN) is an important cause of graft loss in renal transplant recipients B K viremia occurs in up to 30% of renal transplant recipients. Since the discovery of BKV in 1971, effective prophylaxis and treatment have not been established, and it is not uncommon for a transplant kidney to be lost without cure of BKVAN. BK virus infection is reactivated when cellular immunity is suppressed, which is often during the first year after kidney transplantation when cellular immunity is most suppressed.

Wnt signal-dependent antero-posterior specification of early-stage CNS primordia modeled in EpiSC-derived neural stem cells.

The specification of the embryonic central nervous system (CNS) into future brain (forebrain, midbrain, or hindbrain) and spinal cord (SC) regions is a critical step of CNS development. A previous chicken embryo study indicated that anterior epiblast cells marked by N2 enhancer activity are specified to the respective brain regions during the transition phase of the epiblast to the neural plate-forming neural primordium. The present study showed that the SC precursors positioned posterior to the hindbrain precursors in the anterior epiblast migrated posteriorly in contrast to the anterior migration of brain precursors.

Epiblast cells gather onto the anterior mesendoderm and initiate brain development without the direct involvement of the node in avian embryos: Insights from broad-field live imaging.

Live imaging of migrating and interacting cells in developing embryos has opened a new means for deciphering fundamental principles in morphogenesis and patterning, which was not possible with classic approaches of experimental embryology. In our recent study, we devised a new genetic tool to sparsely label cells with a green-fluorescent protein in the broad field of chicken embryos, enabling the analysis of cell migration during the early stages of brain development. Trajectory analysis indicated that anterior epiblast cells from a broad area gather to the head axis to form the brain primordia or brain-abutting head ectoderm.

Live imaging of avian epiblast and anterior mesendoderm grafting reveals the complexity of cell dynamics during early brain development.

Despite previous intensive investigations on epiblast cell migration in avian embryos during primitive streak development before stage (st.) 4, this migration at later stages of brain development has remained uninvestigated. By live imaging of epiblast cells sparsely labeled with green fluorescence protein, we investigated anterior epiblast cell migration to form individual brain portions.

[A CASE REPORT OF VESICAL CALCULUS FORMATION WITH CHROMIC CATGUT AT THE URETEROVESICAL ANASTOMOTIC SITE 28 YEARS AFTER RENAL TRANSPLANTATION].

A 69-year-old man underwent renal transplantation due to chronic renal failure of unknown cause in 1991. Furthermore, in 2012 he again underwent renal transplantation due to renal graft dysfunction with focal segmental glomerulosclerosis. After the second renal transplantation, his renal function has been stable.

Modeling early stages of endoderm development in epiblast stem cell aggregates with supply of extracellular matrices.

Endoderm precursors expressing FoxA2 and Sox17 develop from the epiblast through the gastrulation process. In this study, we developed an experimental system to model the endoderm-generating gastrulation process using epiblast stem cells (EpiSCs). To this end, we established an EpiSC line i22, in which enhanced green fluorescent protein is coexpressed with Foxa2.

The absence of SOX2 in the anterior foregut alters the esophagus into trachea and bronchi in both epithelial and mesenchymal components.

In the anterior foregut (AFG) of mouse embryos, the transcription factor SOX2 is expressed in the epithelia of the esophagus and proximal branches of respiratory organs comprising the trachea and bronchi, whereas NKX2.1 is expressed only in the epithelia of respiratory organs. Previous studies using hypomorphic alleles have indicated that reduced SOX2 expression causes the esophageal epithelium to display some respiratory organ characteristics.

The efficacy and safety of anti-interleukin-6 receptor monoclonal blockade in a renal transplant patient with Castleman disease: early post-transplant outcome.

Background: Multicentric Castleman disease (MCD) is an uncommon lymphoproliferative disease characterized by systemic inflammatory reactions associated with the dysregulated production of interleukin-6 (IL-6). In patients with MCD, renal involvement is uncommon, with only one report published regarding kidney transplantation (KTx) to treat end-stage renal disease (ESRD) secondary to MCD. Recent clinical observations have shown that IL-6 production is implicated in allograft rejection, while IL-6 receptor blockade (with tocilizumab [TCZ]) reduces alloantibody generation and thereby improves graft survival; however, the efficacy and safety of TCZ in MCD patients undergoing KTx is still unknown.

Microscopic polyangiitis necrotizing glomerulonephritis associated with pregnancy: case with a 20-year clinical course and review of the literature.

A 29-year-old woman with past medical history of hypertension was referred to our hospital for the evaluation of kidney dysfunction (serum creatinine 1.0 mg/dL), proteinuria (0.54 g/gCre), and microscopic hematuria.
