Objective: Introduction: The clinical course of acute respiratory viral infections was not sufficiently studied, specially the state of oxidative homeostasis in children with influenza stomatitis. This fact became the base for our study. The aim: to characterize the state of oxidative-prooxidant system as one of the factors of non-specific resistance of children` organism with influenza stomatitis.
Patients And Methods: Materials and methods: A survey was conducted on 384 children with acute respiratory viral infections aged from 6 months to 12 years, among them 318 had lesions of oral cavity. The mild form was diagnosed in 52 children, moderately severe - in 185, severe - in 81 children. The control group consisted of children without lesions of oral cavity (66 people). To analyze lipid peroxidation we used a spectrophotometric determination of diene conjugates. The ceruloplasmin activity and the transferrin saturation in blood plasma by iron were determined by G. Babenko's method.
Results: Results: We found the intensification of lipid peroxidation: a significant increase of diene conjugates in serum up to 13.78 %, the level of which depended on the severity of disease. We also found the activity increase of ceruloplasmin in 1,8 times in patients with severe course of disease. The saturation of blood plasma transferrin by iron was significantly reduced - for 15.27 % in patients with severe course of influenza stomatitis.
Conclusion: Conclusions: Changes in antioxidant system happend due to the activation of lipid peroxidation, and because of the inability to neutralize toxic metabolites in the children` body the intoxication syndrome developed.

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality globally, with oxidative stress playing a pivotal role in its progression. Free radicals produced via oxidative stress contribute to lipid peroxidation, leading to subsequent inflammatory responses, which then result in atherosclerosis. Antioxidants inhibit these harmful effects through their reducing ability, thereby preventing oxidative damage.

Ferroptosis is a unique cell death mode that relies on iron and lipid peroxidation (LPO) and is extensively utilized to treat drug-resistant tumor. However, like the other antitumor model, requirement of oxygen limited its application in treating the malignant tumors in anaerobic environments, just as photodynamic therapy, a very promising anticancer therapy. Here, we show that an iridium(III) complex (Ir-dF), which was often used in proton-coupled electron transport (PCET) process, can induce efficient cell death upon photo irradiation, which can be effectively protected by the typical ferroptosis inhibitor Fer-1 but not by the classic iron chelating agents and ROS scavengers.

Ethylene glycol (EG) has been employed as a cryoprotectant for many years in mammalian semen cryopreservation but not assessed for birds except for its recently illustrated beneficial effects on commercial chicken lines. The Indian red jungle fowl is facing trouble in its native range due to human encroachment. Therefore, the present study was designed to elucidate the cryoprotective effect of different EG concentrations (5%, 10%, 15%, and 20%) on frozen Indian red jungle fowl semen.

Hydrogen sulfide (HS) is a gas signaling molecule with versatile bioactivities; however, its exploitation for disease treatment appears challenging. This study describes the design and characterization of a novel type of HS donor-drug conjugate (DDC) based on the thio-ProTide scaffold, an evolution of the ProTide strategy successfully used in drug discovery. The new HS DDCs achieved hepatic co-delivery of HS and an anti-fibrotic drug candidate named hydronidone, which synergistically attenuated liver injury and resulted in more sufficient intracellular drug exposure.

A novel molecular design based on a quinazolinone scaffold was developed the attachment of aryl alkanesulfonates to the quinazolinone core through a thioacetohydrazide azomethine linker, leading to a new series of quinazolinone-alkanesulfonates 5a-r. The antimicrobial properties of the newly synthesized quinazolinone derivatives 5a-r were investigated to examine their bactericidal and fungicidal activities against bacterial pathogens like , (Gram-positive), , , (Gram-negative), in addition to (unicellular fungal). The tested compounds demonstrated reasonable bactericidal activities compared to standard drugs.
