Background: Diabetic kidney disease (DKD) stands as a primary contributor to end-stage renal disease, associated with heightened mortality in cardiovascular diseases. This study aimed to explore the impact of an eight-week high-intensity interval training (HIIT) on renal injury in diabetic rats.

Methods: Twenty-eight male Wistar rats were randomly allocated into four groups: healthy control (CTL), diabetic control (DC), exercise (EX), and diabetes-exercise (D + EX). Induction of diabetes in the DC and D + EX groups occurred through a two-month high-fat diet followed by a single dose of 35 mg/kg streptozotocin (STZ). Rats in the EX and D + EX groups underwent 4-10 intervals of HIIT (80-100% Vmax) over 8 weeks. Subsequently, pathological and biochemical parameters were assessed in the serum and kidney tissue of the experimental groups.

Results: In the DC group, diabetes led to elevated kidney damage, glomerulosclerosis, fasting blood glucose (FBG), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index, animal weight, kidney dysfunction, albuminuria, and glomerular filtration rate. Additionally, serum and kidney levels of fetuin-A increased, along with kidney levels of KIM-1. Mechanistically, diabetes induction resulted in kidney inflammation by elevating levels of tumor necrosis factor-alpha (TNF-α), transforming growth factor beta (TGF-β), and interleukin 6 (IL-6), while reducing IL-10 levels and increasing the IL-6/IL-10 ratio. Furthermore, diabetes triggered renal oxidative stress, evidenced by increased Malondialdehyde (MDA) levels and decreased levels of glutathione peroxidase (GPx), catalase, and superoxide dismutase (SOD). HIIT mitigated the adverse effects of diabetes in the D + EX group compared to the DC group.

Conclusion: Our findings suggest that HIIT ameliorates type 2 diabetes (T2D)-induced kidney damage by mitigating inflammation, lowering serum levels of fetuin-A, and bolstering antioxidant defenses. This study highlights the potential of HIIT as a time-efficient intervention for diabetic nephropathy

Hepatorenal syndrome-acute kidney injury (HRS-AKI) occurs in the setting of advanced chronic liver disease, portal hypertension, and ascites. HRS-AKI is found in ∼20% of patients presenting to the hospital with AKI, but it may coexist with other causes of AKI and/or with preexisting chronic kidney disease, thereby making the diagnosis challenging. Novel biomarkers such as urinary neutrophil gelatinase-associated lipocalin may be useful.

Introduction: Electrical injuries (EIs) represent a significant clinical challenge due to their complex pathophysiology and variable presentation, ranging from minor burns to severe internal organ damage. Despite their prevalence in both; domestic and occupational settings, there remains a rareness of systematic guidelines and comprehensive literature to aid clinicians in effectively managing these injuries. Understanding these factors is crucial for developing protocols that can mitigate the risk of delayed complications, such as cardiac arrhythmias, in patients who initially appear stable.

Diabetes nephropathy (DN) is a severe diabetic chronic microvascular complication and the major cause of end-stage renal disease (ESRD). Our study aimed to investigate the effects of isoliquiritigenin (ISL) a natural flavonoid compound on DN and to explore the underlying mechanisms. The db/db mice were received intragastric treatments of ISL (5, 10, or 20 mg/kg), vehicle or positive drug metformin (300 mg/kg) once a day for 12 weeks, and the db/m mice treated with vehicle were used as controls.

Because acute kidney injuries (AKI) are one of the critical health problems worldwide, studies on the risk factors, mechanisms, and treatment strategies seem necessary. Glycerol (GLY), known to induce cell necrosis via myoglobin accumulation in renal tubules, is widely used as an AKI model. This study aimed to evaluate the protective effects of gallic acid (GA) against GLY-induced AKI.
