Background: Microbiota of the distal part of the intestine produces Urolithin A (Uro A) as a derivative of ellagitannins hydrolysis. Recently, the mitophagy, anti-inflammatory, and antioxidant properties of Uro A have focused more attention on its probable beneficial effects on neurodegenerative states. The purpose of this research was to study the impact of Uro A on the histopathology of the cerebellum in a rat model of streptozotocin-induced Alzheimer's disease.

Background: Microvascular dysfunction (MVD) is a recognized sign of disease in heart failure progression. Intact blood vessels exhibit abnormal vasoreactivity in early stage, subsequently deteriorating to rarefaction and reduced perfusion. In managing heart failure with preserved ejection fraction (HFpEF), earlier diagnosis is key to improving management.

Hyperuricemia-related diabetic wounds are notoriously difficult to treat due to elevated uric acid (UA) levels, excessive reactive oxygen species (ROS), and chronic inflammation. Current therapies often fail to address these underlying causes, underscoring the need for innovative approaches that not only clear UA but also mitigate inflammation and promote tissue regeneration. In this study, we developed a polyrotaxane-based microsphere (HPR MS) system conjugated with 4,5-diamino-2-thiouracil (DT) to achieve high-affinity UA clearance without increasing cytotoxicity.

Unlabelled: Cytarabine (CTR) is a hydrophilic anticancer drug used to treat leukemia. It suffers from poor permeability and intestinal metabolism, diminishing its oral bioavailability.
Background/objectives: The objective was to develop and evaluate niosomes and bilosomes for enhanced intestinal absorption; hence, oral bioavailability.
