The paper gives the results of a clinical and biochemical study of 165 patients with urolithiasis and 46 healthy persons. Their urinary samples and renal biopsy specimens were analysed to assess the structural and functional status of nephron cell membranes. In urolithiasis patients, the urine was found to contain a great quantities of emulsified lipids enriched in toxic phospholipid and cholesterol metabolism products; renal tissue cytomembranes in the patients were depleted of phospholipids, free cholesterol and enriched in phospholipid lysoforms and cholesterol esters. Lipid phase destabilization of nephron epithelial membranes was shown to be pathogenetically associated with concrement formation. The examination of emulsified urinary lipids is an objective tool of renal tissue crystallization activity and may be recommended for the early diagnosis of urolithiasis, as well as an indicator of membrane-stabilizing therapy efficiency.

Purpose: Renal medullary carcinoma (RMC) is a highly aggressive malignancy defined by the loss of the SMARCB1 tumor suppressor. It mainly affects young individuals of African descent with sickle cell trait, and it is resistant to conventional therapies used for other renal cell carcinomas. This study aimed to identify potential biomarkers for early detection and disease monitoring of RMC.

Hypertension, commonly known as high blood pressure, is a significant health issue that increases the risk of cardiovascular diseases, stroke, and renal failure. This condition broadly encompasses both primary and secondary forms. Despite extensive research, the underlying mechanisms of systemic arterial hypertension-particularly primary hypertension, which has no identifiable cause and is affected by genetic and lifestyle agents-remain complex and not fully understood.

Nickel pollution adversely affects human health and causes various disorders, mainly hepatic and renal dysfunction. The present work focused on a comparative evaluation of the pure form of curcumin (CU) with curcumin-encapsulated chitosan nanoconjugates (CS/CU NCs), on mitigation of the delirious effects of Ni on hepatorenal tissue. Forty-two male rats were allocated into 6 groups (n = 7 for each) as follows: (1) control, (2) CU, (3) CS/CU NCs, (4) Ni, (5) Ni + CU, (6) Ni + CS/CU NCs.

Acute kidney injury (AKI) is one of the most serious and common complications in the course of sepsis, known for its poor prognosis and high mortality rate. Recently, ferroptosis, as a newly discovered regulatory cell death, might be closely associated with the progression of AKI. METTL14 is a writer of RNA m6A, an abundant epigenetic modification in transcriptome with broad function.

Introduction: Lupus nephritis (LN), caused by immune complexes produced or deposited from the bloodstream, is one of the most severe features of Systemic Lupus Erythematosus (SLE) leading to an increased morbidity and mortality. Toll like receptors (TLRs), such as TLR3, TLR7 and TLR9, may play a key role in its pathogenesis. Interleukin-32 (IL-32), a cytokine involved in both innate and adaptive immune responses, has been widely considered in autoimmune-inflammatory rheumatic diseases.
