Insights into renal damage in hyperuricemia: Focus on renal protection (Review).

The incidence of hyperuricemia has increased recently, posing a serious threat to public health. Hyperuricemia is associated with an increased risk of gout, chronic kidney disease (CKD), obesity, metabolic syndrome, type 2 diabetes mellitus, hypertension, hypertriglyceridaemia, metabolic dysfunction‑associated steatotic liver disease, acute kidney injury, coronary heart disease and cardiovascular disease (CVD). These diseases are commonly accompanied by varying degrees of kidney damage.

Stimulating the Potential of Zn Anodes to Operate in Low pH and Harsh Environments forHighly Sustainable Zn Batteries.

Compared to near-neutral electrolytes (pH=3-6), Zn||Mn batteries in acidic environments can achieve voltages up to ~2 V. However, high proton concentrations raise concerns about Zn anode stability. Current strategies for inhibiting hydrogen evolution corrosion (HEC) on the anode in Zn-based batteries mainly focus on the near-neutral electrolytes.

Magnetic iron oxide nanoparticles: An emerging threat for the environment and human health.

Magnetic iron oxide nanoparticles (FeO NPs, mainly FeO and γ-FeO) are nanomaterials ubiquitously present in aquatic, terrestrial, and atmospheric environments, with a high prevalence and complex sources. Over the past decade, numerous reports have emerged on the presence of exogenous particles in human body, facilitated by the rapid development of separation and detection methods. The health risk associated with magnetic FeO NP have garnered escalating attention due to their presence in human blood and brain tissues, especially for their potential association with neurodegenerative diseases like Alzheimer's disease.

CITED2 Mediates Metabolic Reprogramming in Renal Tubular Epithelial Cells via the AKT Signaling Pathway to Induce Sepsis-Associated Acute Kidney Injury.

Background: Sepsis-associated acute kidney injury (S-AKI) is a prevalent and severe clinical complication in intensive care units (ICUs) and is associated with high mortality and poor prognosis. The dysfunction of renal tubular epithelial cells (TECs), particularly through their metabolic reprogramming, plays a critical role in the onset and progression of S-AKI. CITED2 is shown to regulate a variety of cellular processes, but its specific impact on TECs metabolism and S-AKI pathogenesis remains unclear.
