Experiments on rats showed that complete Freund's adjuvant-induced low-grade fever and pyrogenal-induced fever of different duration are accompanied by an increase in the content of lipid peroxidation products and components of the antioxidant system not only in blood plasma, but also in the central lymph. These changes reflect activation of drainage, evacuation, and transport function of the lymphatic system. We conclude that the lymphatic system plays an important role in the maintenance of the prooxidant-antioxidant balance under these pathological conditions.

Tityus serrulatus accident promote vast symptomatology related to toxins of the venom, which leads to a massive release of neurotransmitters, notably dopamine, affecting behavior and neurochemistry. The recommended treatment for envenomation is the antiscorpionic serum (SAEsc) administration. Related to this complexity of the Tityus serrulatus envenomation, this study aimed to assess organism responses to the venom, its impact on behavior, oxidative stress, neurochemistry, and genetic impacts, as well as the efficacy of SAEsc, especially concerning dopamine levels and genetic interactions.

Objective: The purpose of this work was to investigate whether resveratrol affects lead-induced oxidative damage in HT-22 cells, characterizing mechanisms and strategies for preventing and treating lead-induced neurotoxicity.
Methods: Various lead and resveratrol concentrations were applied to HT-22 cells over different time periods. First, we established the lead treatment (12.
Chronic environmental exposure to polystyrene microplastics increases the risk of nonalcoholic fatty liver disease.

Microplastics (MPs), as the crucial environmental pollutants, can be easily transported into the human body and accumulate in the liver. However, current studies mainly focus on acute exposure to MPs, investigations on long-term interactions with MPs alone remain limited. Thereby, we examined noxious properties of MPs and selected the most common polystyrene (PS) MPs as the research object, including unmodified PS MPs (PS-MPs) and positive-charged PS MPs (PS-NH) at 10 mg/L employing oral drinking water methods in mice for six consecutive months in vivo.

Objective: Patients with osteosarcoma (OS) exhibit metastasis upon diagnosis, and the condition frequently acquires resistance to traditional chemotherapy treatments, failing the therapy. The objective of this research was to examine the impact of curculigoside (Cur), a key phenolic compound discovered in the rhizome of C. orchioides Gaertn, on OS cells and the surrounding tumor environment.

Hemorrhagic shock and reperfusion (HSR) is the main cause of death following trauma. Cognitive impairment may persist after successful resuscitation from hemorrhagic shock, but the mechanisms remain elusive. This study demonstrated the presence of ferroptosis in an in vitro model of oxygen-glucose deprivation and reoxygenation (OGD/R) in HT22 neurons, and also in a murine model of HSR using 3-month-old C57BL/6 mice.
