Background: This study was designed to determine possible protective effect of betaine treatment against oxidative injury in pulmonary tissue induced with thermal trauma.
Methods: Under ether anesthesia, shaved dorsum of Wistar albino rats was exposed to a 90°C water bath for 10 seconds to induce burn injury. Betaine was administered orally (250 mg/kg) for a period of 21 days before burn injury, and single dose of betaine was administered after thermal injury. Control group rats were exposed to 25°C water bath for 10 seconds. Upon conclusion of experiment, rats were decapitated and blood was collected for analysis of pro-inflammatory cytokines and lactate dehydrogenase (LDH) activity. Lung tissue samples were taken to determine malondialdehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO), and Na+/K+-ATPase activity, in addition to histological analysis.
Results: Burn injury caused significant increase in both cytokine levels and LDH activity. In lung samples, raised MDA levels, MPO activity, and reduced GSH levels and Na+/K+-ATPase activity were found due to burn injury.
Conclusion: Treatment of rats with betaine significantly restored GSH level and Na+/K+-ATPase activity, and decreased MDA level and MPO activity. According to the findings of the present study, betaine significantly diminishes burn-induced damage in tissue.

Pyoderma, commonly known as impetigo, is a bacterial skin infection causing pus formation, prevalent globally, especially in resource-poor areas. It affects both children and adults, including those with conditions like diabetes. Despite its significant impact and economic burden, research on its global epidemiology is limited.

Purpose: Previous studies have reported divergent sexual responses to aging; however, specific variations in gene expression between aging males and females and their potential association with age-related retinal diseases remain unclear. This study collected data from public databases and developed a comprehensive comparison of retina between aging females and males.
Methods: Single-cell RNA (scRNA) and bulk RNA sequencing data of the aging retina from females and males in public databases were utilized for integrated analysis to investigate sex-biased expression in retina.
