BACKGROUND: Adenosine deaminase acting on RNA 1 (ADAR1) is an RNA-editing enzyme that significantly impacts cancer progression and various biological processes. The expression of ADAR1 mRNA has been examined in multiple cancer types using The Cancer Genome Atlas (TCGA) dataset, revealing distinct patterns in kidney chromophobe (KICH), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), and liver hepatocellular carcinoma (LIHC) compared to normal controls...

Chronic kidney disease (CKD) is a major contributor to morbidity and mortality in sickle cell disease (SCD). Anemia, induced by chronic persistent hemolysis, is associated with progressive deterioration of renal health resulting in CKD. Moreover, patients with SCD experience acute kidney injury (AKI), a risk factor for CKD, often during vasoocclusive crisis associated with acute intravascular hemolysis. However, the mechanisms of the hemolysis-driven pathogenesis of the AKI-to-CKD transition in SCD remain elusive...

Although dietary potassium restriction is an acceptable approach to hyperkalemia prevention, it may be insufficient for outpatients with chronic kidney disease (CKD). Most outpatients with CKD use community pharmacies owing to the free access scheme in Japan. The MieYaku-CKD project included a community pharmacist-led nutritional intervention for dietary potassium restriction, with the goal of determining its efficacy for patients' awareness of potassium restriction and serum potassium levels in outpatients with CKD...

BACKGROUND: Renal proximal tubule plays a pivotal role in regulating sodium reabsorption and thus blood pressure. Transient receptor potential ankyrin 1 (TRPA1) has been reported to protect against renal injury by modulating mitochondrial function. We hypothesize that the activation of TRPA1 by its agonist cinnamaldehyde may mitigates high salt intake induced hypertension by inhibiting urinary sodium reabsorption through restoration of renal tubular epithelial mitochondrial function. METHODS: Trpa1-deficient (Trpa1-/-) mice and wild-type (WT) mice were fed standard laboratory chow [normal diet (ND) group, 0...

New treatment options and low attack-related mortality have changed the life expectancy of patients with acute porphyria (AP) to that of the general population. Clinicians should therefore be aware of the long-term complications of AP, which typically include chronic neuropathy and encephalopathy, high blood pressure and porphyria-associated kidney disease. Patients have an increased risk of primary liver cancer (PLC), but no increased risk of non-hepatic cancers. Chronic pain occurs in patients with recurrent attacks, combined with chronic fatigue and nausea, leading to poor quality of life...

CONTEXT: End-stage renal disease (ESRD) refers to the development of chronic kidney disease to stage 5. Elevated blood pressure is one of the main symptoms of older adults with ESRD. The severity and difficulty of curing ESRD with hypertension in older adults has attracted a great deal of attention from the medical community. OBJECTIVE: The study intended to analyze the correlation between blood-pressure level and FRAIL scores and adverse health events for older adults with ESRD and hypertension...

OBJECTIVE: This study explicitly demonstrates the roles of natural killer (NK) cells in different types of kidney transplantation. METHODS: We'd done the whole study from October 2022 to October 2023. To further explore the significance of NK cells during renal transplantation, we provide a theoretical basis for clinically overcoming immune rejection after renal transplantation by developing new anti-rejection drugs. We selected twelve male mice and divided them into three groups (Syngeneic transplant group allograft transplant group allograft transplant (priming) group) by random...

INTRODUCTION: This study was designed to investigate whether renal α-klotho levels are associated with renal pathology. This is the first report on patients with chronic kidney disease (CKD). METHODS: We conducted a retrospective observational study. A total of 65 CKD patients were enrolled. Serum and renal biopsy samples were collected. Estimated glomerular filtration rate (eGFR) was examined by biochemical test. And α-klotho expressions were assessed by RT-PCR and immunohistochemistry...

BACKGROUND: Interleukin-18 (IL-18), also known as interferon-gamma inducing factor is a protein which in humans is encoded by the IL18 gene, it is a member of the IL 1 family and has a molecular weight of 18 kDa. Innate and adaptive immunity can be regulated by IL-18, and disorders involving its dysregulation might result in inflammatory or autoimmune conditions. AIM OF THE WORK: To distinguish between acute kidney injury (AKI) and chronic renal failure (CRF), this research investigates the utility of IL-18 as a novel biomarker and examines how age affects its level...

BACKGROUND: Uncontrolled donation after circulatory death (uDCD) increases organ availability for kidney transplantation (KT) at the expense of a higher risk of primary graft nonfunction (PNF). At least half of the cases of PNF are secondary to graft venous thrombosis. The potential benefit from prophylactic anticoagulation in this scenario remains unclear. METHODS: In this single-center retrospective study we compared 2 consecutive cohorts of KT from uDCD with increased (≥0...

INTRODUCTION: Kidneys are a retroperitoneal organ but the widely practiced laparoscopic approach to renal surgery is transperitoneal due to the advantages of greater working space at the cost of entering the peritoneal cavity, risk of injury to intraperitoneal organs, and the increased risk of postoperative bowel complications. The classic open approach to kidney procedures has been the flank approach without violating the peritoneal cavity instead of the retroperitoneal approach to renal surgery with the advantages of direct access to the renal hilum, especially the renal artery...

Antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (GN) is an immune-mediated kidney disease characterized by the inflammation of small blood vessels in the kidney, leading to renal impairment and potentially irreversible damage. Concerns have been raised over the reports of myeloperoxidase/perinuclear (MPO/p) ANCA GN following the coronavirus disease 2019 (COVID-19) vaccination. Our study provides a comprehensive insight into perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA) GN after COVID-19 vaccination...

INTRODUCTION: Kidney tumors have an important place among urological malignancies. The increased utilization of imaging methods has led to a rise in renal cell carcinoma (RCC) diagnoses, albeit with declining mortality rates, particularly in developed countries. Radical nephrectomy remains the gold standard treatment. The aim of this study was to share a tertiary oncology hospital's initial experiences with laparoscopic nephrectomy. MATERIALS AND METHODS: This retrospective study analyzes data from patients who underwent laparoscopic nephrectomy, focusing on demographic characteristics, tumor features, and operative outcomes...

BACKGROUND: Acute kidney injury (AKI) is a common clinical syndrome with high morbidity and mortality rates. The use of pluripotent stem cells holds great promise for the treatment of AKI. Urine-derived stem cells (USCs) are a novel and versatile cell source in cell-based therapy and regenerative medicine that provide advantages of a noninvasive, simple, and low-cost approach and are induced with high multidifferentiation potential. Whether these cells could serve as a potential stem cell source for the treatment of AKI has not been determined...

BACKGROUND: To investigate the diagnostic efficacy of high-frame-rate contrast-enhanced ultrasound (H-CEUS) in differentiating between clear cell renal cell carcinoma (CCRCC) and angiomyolipoma (AML). METHODS: A retrospective study was performed on the clinical data of 79 patients diagnosed with CCRCC and 31 patients diagnosed with AML at the First Affiliated Hospital of Nanchang University between October 2022 and December 2023. Conventional ultrasound (US) and H-CEUS examinations were conducted on all patients prior to surgery, dynamic images were recorded from the US, and the qualitative and quantitative parameters of H-CEUS were collected...

INTRODUCTION: ACE cleaves angiotensin I (Ang I) to angiotensin II (Ang II) inducing vasoconstriction via Ang II type 1 (AT1) receptor, while ACE2 cleaves Ang II to Ang (1-7) causing vasodilatation by acting on the Mas receptor. In diabetic kidney disease (DKD), it is still unclear whether plasma or urine ACE2 levels predict renal outcomes or not. RESEARCH DESIGN AND METHODS: Among 777 participants with diabetes enrolled in the Urinary biomarker for Continuous And Rapid progression of diabetic nEphropathy study, the 296 patients followed up for 9 years were investigated...

Group 3 innate lymphoid cells (ILC3s) regulate inflammation and tissue repair at mucosal sites, but whether these functions pertain to other tissues-like the kidneys-remains unclear. Here, we observed that renal fibrosis in humans was associated with increased ILC3s in the kidneys and blood. In mice, we showed that CXCR6+ ILC3s rapidly migrated from the intestinal mucosa and accumulated in the kidney via CXCL16 released from the injured tubules. Within the fibrotic kidney, ILC3s increased the expression of programmed cell death-1 (PD-1) and subsequent IL-17A production to directly activate myofibroblasts and fibrotic niche formation...

Background Chronic kidney disease (CKD) is a progressive systemic condition characterized by numerous complications. Among these, alterations in skeletal muscle physiology, such as sarcopenia, are particularly significant, as they are associated with poor outcomes and reduced quality of life. Summary Various interventions, including pharmacological approaches and lifestyle modifications have been investigated to slow CKD progression and prevent or treat its complications. Physical exercise, in particular, has emerged as a promising intervention with multiple beneficial effects...

BACKGROUND: Quality assessment of modified or processed red blood cell (RBC) components, such as pathogen-reduced RBCs, using only in vitro testing may not always be predictive of in vivo performance. Mouse or rat in vivo models are limited by a lack of applicability to certain aspects of human RBC biology. Here, we used a guinea pig model to study the effects of riboflavin combined with UV light on the integrity of RBCs in vitro and following transfusion in vivo. MATERIALS AND METHODS: Guinea pig RBCs were collected from whole blood (WB) treated with varying UV doses (10, 20, 40 or 80 J/mL) in the presence of riboflavin (UVR-RBCs)...

Hypertension affects approximately 1 in 2 US adults and sex plays an important role in the pathogenesis of hypertension.​ The sodium chloride cotransporter (NCC), regulated by a kinase network including with-no-lysine kinases (WNK) 1 and WNK4, STE20/SPS1-related proline alanine rich kinase (SPAK), and oxidative stress response 1 (OxSR1) is critical to sodium reabsorption and blood pressure regulation. Dietary salt differentially modulates the NCC in salt-sensitive and salt-resistant rats, in part by modulation of WNK/SPAK/OxSR1 signaling...
