Injectable Genetic Engineering Hydrogel for Promoting Spatial Tolerance of Transplanted Kidney in Situ.

The establishment of a tolerant space to realize the co-stimulation of cytokines and contact-dependent molecules remain challenging in allotransplant. Here, an injectable genetically engineered hydrogel (iGE-Gel) is reported, which developed with a multivalent network of FOXP3 engineered extracellular vesicles (Foe-EVs) through the hydrophobic interaction between stearic acid modified hyaluronic acid (HASA) and the membrane phospholipids of extracellular vesicles (EVs). The iGE-Gel exhibited self-healing properties, injectability and biocompatibility.

Integrated multi-omics revealed that dysregulated lipid metabolism played an important role in RA patients with metabolic diseases.

Objectives: Patients with rheumatoid arthritis (RA) commonly experience a high prevalence of multiple metabolic diseases (MD), leading to higher morbidity and premature mortality. Here, we aimed to investigate the pathogenesis of MD in RA patients (RA_MD) through an integrated multi-omics approach.

Methods: Fecal and blood samples were collected from a total of 181 subjects in this study for multi-omics analyses, including 16S rRNA and internally transcribed spacer (ITS) gene sequencing, metabolomics, transcriptomics, proteomics and phosphoproteomics.

Genome-Wide Characterization of the () Zinc Finger Gene Family in and the Functional Analysis of in Shoot Gravitropism.

The plant-specific transcription factors (TFs) are vital for regulating plant growth and developmental processes. However, the characteristics and biological roles of the gene family in tomato () are still largely unexplored. In this study, 17 genes were identified in the tomato genome and classified into seven subgroups according to the evolutionary relationships of IDD proteins.

Urinary Sodium Excretion and Kidney Disease Progression in IgA Nephropathy: A Cohort Study.

Introduction: The role of dietary sodium intake in the risk of chronic kidney disease progression remains controversial. This study aimed to evaluate the association of urinary sodium excretion and progression of IgA nephropathy.

Methods: We assessed 596 patients with IgA nephropathy, and urinary sodium excretion was measured at the time of kidney biopsy.

Experimental models for preclinical research in kidney disease.

Acute kidney injury (AKI) and chronic kidney disease (CKD) are significant public health issues associated with a long-term increase in mortality risk, resulting from various etiologies including renal ischemia, sepsis, drug toxicity, and diabetes mellitus. Numerous preclinical models have been developed to deepen our understanding of the pathophysiological mechanisms and therapeutic approaches for kidney diseases. Among these, rodent models have proven to be powerful tools in the discovery of novel therapeutics, while the development of kidney organoids has emerged as a promising advancement in the field.

A modified open surgical revision technique for malfunctioning peritoneal dialysis catheter.

The malfunction of peritoneal dialysis (PD) catheter is still an intractable problem. A modified open surgical revision technique with suturing fixation and without catheter removal for malfunctioning catheter was developed to evaluated the efficacy and safety between simultaneous catheter replacement technique. A total of 167 PD patients with malfunctioning catheter were retrospectively reviewed.

Systemic Analyses of Anti-Cell-Senescence Active Compounds in Sect. Chang and Their Mechanisms.

Aging is an irreversible pathophysiological process for all organisms. The accumulation of senescent cells in pathological sites or tissues is recognized as the major cause of diseases and disorders during the aging process. Small molecules that reduce senescent cell burdens have gained increasing attention as promising intervention therapeutics against aging, but effective anti-senescence agents remain rare.

Obinutuzumab in Refractory Membranous Nephropathy: A Case Series.

Rationale & Objective: Membranous nephropathy (MN), recognized as an autoimmune kidney disease, responds well to anti-CD20 monoclonal antibodies. Obinutuzumab, a type Ⅱ humanized anti-CD20 and immunoglobulin G1 Fc-optimized monoclonal antibody, when compared with rituximab, has demonstrated superior efficacy in B-cell leukemia and lymphoma, especially in rituximab-resistant cases. However, the efficacy and safety of obinutuzumab in MN remain unclear.

Irisin preserves mitochondrial integrity and function in tubular epithelial cells after ischemia-reperfusion-induced acute kidney injury.

Aims: A myokine secreted by skeletal muscles during exercise called irisin mitigates ischemia-reperfusion (I/R) injury in epithelial cells of various organs by limiting damage to mitochondria. We test whether irisin may preserve the mitochondrial integrity and function in renal tubular epithelial cells and protect against ischemia-reperfusion-induced acute kidney injury (AKI).

Methods: We correlated serum irisin levels with serum creatinine and BUN levels from both AKI patients and healthy individuals.

: A challenging diagnosis in a kidney transplant patient.

Key Clinical Message: In addition to post-transplant lymphoproliferative disorders, it is necessary to be alert to the drug-resistant bacteria or fungal infection, especially , in kidney transplant patients who have failed antibiotic treatment and whose PET-CT indicates high metabolic mass in the transplanted kidney with a large number of other organs and lymph nodes.

Abstract: (TM) is a rare pathogenic fungus that primarily affects individuals with compromised immune systems. Post-transplant lymphoproliferative disorders (PTLD) are serious complications that can occur after solid organ and cell transplantation.

Clinical characteristics and outcomes of hospitalized kidney transplant recipients with COVID-19 infection in China during the Omicron wave: a single-center cohort study.

: Following the short-term outbreak of coronavirus disease 2019 (COVID-19) in December 2022 in China, clinical data on kidney transplant recipients (KTRs) with COVID-19 are lacking. : We conducted a single-center retrospective study to describe the clinical features, complications, and mortality rates of hospitalized KTRs infected with COVID-19 between Dec. 16, 2022 and Jan.

The Efficacy and Safety of Roxadustat for the Treatment of Posttransplantation Anemia: A Randomized Study.

Introduction: Roxadustat, an oral hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor, can stimulate erythropoiesis. Our objective was to evaluate the efficacy and safety of roxadustat for the treatment of posttransplantation anemia (PTA).

Genome-Wide Identification and Expression Analysis of the PHD Finger Gene Family in Pea ().

The plant homeodomain finger (PHD finger) protein, a type of zinc finger protein extensively distributed in eukaryotes, plays diverse roles in regulating plant growth and development.

In this study, we identified 84 members of the PHD finger gene family in pea, which displayed an uneven distribution across seven chromosomes.

Deciphering three predominant biopsy-proven phenotypes of IgG4-associated kidney disease: a retrospective study.

Background: IgG4-associated kidney disease (IgG4-RKD) encompasses a spectrum of disorders, predominantly featuring tubulointerstitial nephritis (TIN) and membranous glomerulonephropathy (MGN). The limited understanding of the co-occurrence of IgG4-RD-TIN with anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) poses a diagnostic and therapeutic challenge.

Methods: We examined 49 cases, comprising 21 cases of IgG4-RD-TIN (group A), 10 cases of IgG4-RD-TIN accompanied with MGN (group B), and 18 cases of IgG4-RD-TIN concurrent with AAV (group C), at the First Affiliated Hospital of Zhejiang University, China, from June 2015 to December 2022.
