Introduction: This study aimed to describe the course of patients with lung cancer from treatment initiation to end-of-life.

Methods: This retrospective cohort study used Claims Data from the National Health Insurance and Advanced Elderly Medical Service System. We analyzed data from patients newly diagnosed with lung cancer between April 2013 and March 2021 who had been hospitalized at our University Hospital in urban area.

A Pragmatic Method to Integrate Data From Preexisting Cohort Studies Using the Clinical Data Interchange Standards Consortium (CDISC) Study Data Tabulation Model: Case Study.

Background: In recent years, many researchers have focused on the use of legacy data, such as pooled analyses that collect and reanalyze data from multiple studies. However, the methodology for the integration of preexisting databases whose data were collected for different purposes has not been established. Previously, we developed a tool to efficiently generate Study Data Tabulation Model (SDTM) data from hypothetical clinical trial data using the Clinical Data Interchange Standards Consortium (CDISC) SDTM.

BMP4-SMAD1/5/9-RUNX2 pathway activation inhibits neurogenesis and oligodendrogenesis in Alzheimer's patients' iPSCs in senescence-related conditions.

In addition to increasing β-amyloid plaque deposition and tau tangle formation, inhibition of neurogenesis has recently been observed in Alzheimer's disease (AD). This study generated a cellular model that recapitulated neurogenesis defects observed in patients with AD, using induced pluripotent stem cell lines derived from sporadic and familial AD (AD iPSCs). AD iPSCs exhibited impaired neuron and oligodendrocyte generation when expression of several senescence markers was induced.

Association between 3-Year Repetitive Isolated Hematuria and eGFR Deterioration in an Apparently Healthy Population: A Retrospective Cohort Study.

Microscopic hematuria is being increasingly recognized as a major indicator of kidney deterioration. Persistent hematuria may better detect estimated glomerular filtration rate (eGFR) deterioration and potential glomerulonephritis. We conducted a retrospective cohort study to investigate the associations between persistent hematuria: the frequency or consistency of positive dipstick hematuria defined by the preceding 3 years urinalyses, and eGFR deterioration over 5 years and abnormal urinalyses suggesting potential glomerulonephritis (hematuria 1+ or higher, 2+ or higher, proteinuria, and hematuria and proteinuria) 5 years later, among adult participants with positive dipstick hematuria at baseline in a large-scale Japanese health checkup setting (n = 2104).

Identification of High-Risk Groups in Urinalysis: Lessons from the Longitudinal Analysis of Annual Check-Ups.

Background: For effective screening in urinalysis, information on high-risk groups is needed; however, there is a lack of evidence in young adults in particular. The aim of this study was to provide information on urinalysis in young adults and to identify high-risk groups of urinalyses using multi-year data obtained from annual large-scale check-ups.

Method: We used annual health check-up data collected from 2011 to 2016 at Kyoto University in Japan.

Cost Analysis of Screening for IgA Nephropathy Using Novel Biomarkers.

Objectives: IgA nephropathy (IgAN) is the most common primary chronic glomerulonephritis and a major cause of end-stage kidney disease worldwide. Novel biomarkers, including the aberrantly glycosylated IgA1 and glycan-specific antibodies, could be useful in the diagnosis of IgAN. The aim of this study was to assess the cost analysis of IgAN screening using novel biomarkers in addition to the conventional screening compared with conventional screening alone.

The association between depressive symptoms and self-rated health among university students: a cross-sectional study in France and Japan.

Background: Depressive disorders in University students have risen dramatically in the past few decades to the extent that students' mental health has become a current global public health priority. Obtaining information from University students about their mental health is challenging because of potential embarrassment of disclosing one's concerns and fear of stigmatization. Self-rated health might be a good solution to evaluate mental health state by a simple and neutral indicator.

Hematopoietic Stem Cell Transplantation Nephropathy Associated with Chronic Graft-versus-Host Disease without Extrarenal Involvement.

A 30-year-old woman with myelodysplastic syndrome underwent allogeneic hematopoietic stem cell transplantation (HSCT) derived from her HLA-matched sister six years previously. She received preconditioning total body irradiation with renal shielding and was subsequently administered cyclosporin A (CyA) as prophylaxis against graft-versus-host disease (GVHD). Four months after HSCT, asymptomatic proteinuria and glomerular hematuria developed during CyA tapering without obvious extrarenal involvements of GVHD, and persisted for six years.

The COUP-TFII/Neuropilin-2 is a molecular switch steering diencephalon-derived GABAergic neurons in the developing mouse brain.

The preoptic area (POa) of the rostral diencephalon supplies the neocortex and the amygdala with GABAergic neurons in the developing mouse brain. However, the molecular mechanisms that determine the pathway and destinations of POa-derived neurons have not yet been identified. Here we show that Chicken ovalbumin upstream promoter transcription factor II (COUP-TFII)-induced expression of Neuropilin-2 (Nrp2) and its down-regulation control the destination of POa-derived GABAergic neurons.

A new spiroindene pigment from the medicinal fungus Phellinus ribis.

A new spiroindene pigment, phelliribsin A, was isolated from the medicinal fungus Phellinus ribis, and its structure was determined by two dimensional (2D)-NMR methods. Phelliribsin A is an unprecedented spiroindene compound, and was found to have cytotoxic activity against PC12 cells at a concentration of 30 µM.

A Japanese Family Suffering from Familial Juvenile Hyperuricemic Nephropathy due to a Rare Mutation of the Uromodulin Gene.

We report the case of a Japanese family suffering from familial juvenile hyperuricemic nephropathy (FJHN) due to a rare missense mutation of the uromodulin (UMOD) gene. An 18-year-old male presented with gout, hyperuricemia, and stage 3 chronic kidney disease. Mostly, FJHN is caused by a mutation altering the cystine residue of UMOD/Tamm-Horsfall protein.

Association of a novel in-frame deletion mutation of the MYH9 gene with end-stage renal failure: case report and review of the literature.

MYH9 disorders are autosomal dominant diseases characterized by giant platelets, thrombocytopenia, and granulocyte inclusion bodies. These diseases are caused by mutations in the MYH9 gene that encodes nonmuscle myosin heavy chain IIA. We describe the case of a 27-year-old male who presented with macrothrombocytopenia and leukocyte inclusion bodies.

Peritoneal mesothelial cells as a target of local aldosterone action: upregulation of connective tissue growth factor expression via serum- and glucocorticoid-inducible protein kinase 1.

Background/aims: Peritoneal fibrosis can lead to the discontinuation of continuous ambulatory peritoneal dialysis. The present study investigated the direct effect of aldosterone, which influences tissue fibrosis, and its cellular mechanism using cultured rat peritoneal mesothelial cells (RPMCs).

Materials And Methods: The expression of aldosterone synthase (CYP11B2), mineralocorticoid receptors, 11beta-hydroxysteroid dehydrogenase 2, serum- and glucocorticoid-inducible protein kinase 1 (SGK1) and connective tissue growth factor (CTGF) was evaluated using reverse transcriptase-polymerase chain reaction and Western blot.

Expression of Sema3D in subsets of neurons in the developing dorsal root ganglia of the rat.

We investigated the expression of the semaphorin family member, Sema3D, in the developing dorsal root ganglia of the rat. Sema3D expression was observed in a subpopulation of dorsal root ganglion (DRG) neurons. The expression peaked at E15 and thereafter it declined.

Identification and tissue-specific expression of a novel isoform of Semaphorin 3D.

Background: Semaphorins are a family of secreted and membrane-associated proteins involved in axon guidance in the developing brain as well as morphogenesis in various organs. There has been no report on the expression of different transcripts of the genes encoding Class 3 Semaphorins with different protein structures.

Methods: Molecular cloning of rat Semaphorin 3D gene and the expression analysis at gene and protein levels were performed.

SUMO-1 immunoreactivity co-localizes with phospho-Tau in APP transgenic mice but not in mutant Tau transgenic mice.

Sumoylation is a post-translational modification process that is supposed to be implicated in the pathogenesis of several neurodegenerative diseases. Recently, the microtubule-associated protein Tau was identified as a target for sumoylation in the analysis of the transfected cells. We investigated the localization of SUMO-1 protein in APP transgenic mice and mutant Tau transgenic mice, and found that SUMO-1 immunoreactivity was co-localized with phosphorylated Tau aggregates in amyloid plaques of APP transgenic mice.

Reduced pain sensitivity in mice lacking latexin, an inhibitor of metallocarboxypeptidases.

Latexin, the endogenous protein inhibitor of the A/B subfamily of metallocarboxypeptidases, is expressed in small nociceptive neurons in sensory ganglia and in a subset of neurons in the telencephalon. In this study, we generated latexin-deficient mice that exhibited increased tail-flick latency compared to wild-type animals upon noxious heat stimulation. The reduced pain sensitivity in the mutants was rescued by the systemic administration of a plant carboxypeptidase inhibitor that inhibits the A/B subfamily of metallocarboxypeptidases.

Intracellular cAMP controls a physical association of V-1 with CapZ in cultured mammalian endocrine cells.

V-1, an ankyrin repeat protein with the activity to control tyrosine hydroxylase (TH) gene expression and transmitter release in PC12D cells, associates with CapZ, an actin capping protein, and thereby regulates actin polymerization in vitro. In this study, immunoprecipitation and Western blot analysis showed that V-1 was physically associated with CapZ-beta in PC12D transfectants overexpressing V-1. These proteins were co-localized in the soma of Purkinje cells of rat cerebellum as assayed by immunohistochemistry.
