Uric acid is the final product of purine metabolism, and excessive serum uric acid can cause gouty arthritis and uric acid nephropathy. Therefore, lowering the uric acid level and alleviating inflammation in the body are the key points to treating these diseases. A stable nanosuspension of peptide BmK9 was prepared by the precipitation-ultrasonication method. By combining uricase on the surface of a positively charged carrier, a complex consisting of neutral rod-shaped BmK9 and uricase nanoparticles (Nplex) was formed to achieve the delivery of BmK9 and uricase, respectively. The formulation of Nplex has a diameter of 180 nm and drug loading up to 200%, which releases BmK9 and uricase slowly and steadily in drug release tests . There was significantly improved pharmacokinetic behavior of the two drugs because Nplex prolonged the half-life and increased tissue accumulation. Histological assessments showed that the dual drug Nplex can reduce the inflammation response in acute gouty arthritis and chronic uric acid nephropathy . In the macrophage system, there was lower toxicity and increased beneficial effect on inflammation with Nplex than free BmK9 or uricase. Collectively, this novel formulation provides a dual drug delivery system that can treat gouty arthritis and uric acid nephropathy.

Background: Inflammation and hyperuricemia are closely associated with chronic kidney disease (CKD). The systemic inflammation response index (SIRI), systemic immune-inflammation index (SII), monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are emerging as novel biomarkers. While, the synergistic effects of these biomarkers with hyperuricemia on CKD remain unclear.

Globally, the South Asian Cocktail (SAC), a substance of abuse, is becoming popular. The effects of SAC on male fertility are unknown; however, its component pharmaceuticals, such as codeine, rohypnol, and promethazine, have been linked to male infertility. Thus, this study assessed SAC's influence and putative mechanisms on male fertility among SAC consumers.

Prototheca, a genus of opportunistic pathogenic microalgae, can cause protothecosis in humans and animals, manifesting as cutaneous lesions or disseminated/systemic infections. This report describes a rare case of Prototheca wickerhamii toe infection in a 78-year-old Chinese male, presenting initially as gouty arthritis. The patient, who worked in fish farming with frequent water exposure, had a history of herpes zoster and hypertension.

Introduction: The increasing use of biodegradable plastics has led to the inevitable human consumption of biodegradable microplastics (MPs). These MPs can be degraded and absorbed into various organs and tissues via the gastrointestinal tract, with the liver being the primary target for digestion and absorption.
Objectives: This study aimed to investigate the toxic effects and mechanisms of biodegradable MPs on the liver following gastrointestinal degradation.

Background: Obesity has emerged as a critical global public health challenge. Postmenopausal women experience significantly elevated risks of metabolic disorders and a marked increase in obesity prevalence due to declining estrogen levels. The uric acid to high-density lipoprotein cholesterol ratio (UHR), an emerging biomarker for metabolic syndrome, is gaining clinical recognition.
