In the present communication, we report remarkably elevated levels of xanthine oxidase activity in the blood of the patients with myocardial infarction when compared to age and sex matched healthy persons. Highly significant increase of malondialdehyde, serving as an index of lipid peroxidation and thus free radical mediated damage, has also been found in the patients. We propose the measurement of the blood levels of xanthine oxidase, a very simple, reliable and less time consuming method as an indicator of myocardial infarction.

Background: Oxidative stress is formed by a perturbation of redox homeostasis and linked to the development of Alzheimer's disease (AD) [1]. This imbalance results in an abundance of free radicals that exceeds the antioxidant capacity. Xanthine oxidase (XO) is an enzyme responsible for producing uric acid through the metabolism of purine nucleotides, specifically hypoxanthine and xanthine to uric acid [2].

Introduction: Studies show that Pinelliae Rhizoma Praeparatum (PRP) has some pharmacological effects in enhancing immunity and against gout.
Objectives: A mathematical model was created for extraction process optimization, analysis and identification, activity screening, and isolation and purification; moreover, the mechanism of action was studied.
Methods: First, the extraction of PRP was investigated using the gray wolf optimization mathematical regression model; the extraction variables were optimized to maximize the yield.

The serum uric acid-to-creatinine ratio (UCR) may be a simple method for assessing xanthine oxidase overactivation, which may contribute to an increase in serum uric acid production and oxidative stress. In this study, we investigated the nonlinear association between the UCR and long-term mortality in patients with hypertension. Data were acquired from the National Health and Nutrition Examination Survey database, and a total of 11,346 patients with hypertension were included.

Natural Xanthine oxidase (XOD) inhibitors represent promising therapeutic agents for hyperuricemia (HUA) treatment due to their potent efficacy and favorable safety profiles. This study involved the construction of a comprehensive database of 315 XOD inhibitors and development of 28 machine learning-based QSAR models. The ChemoPy light gradient boosting machine model exhibited the best performance (AUC = 0.
