Objectives: The objectives of this study were to evaluate the role of oxidative stress in benign paroxysmal positional vertigo (BPPV) by measuring urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), 8-hydroxy-guanosine (8-OHG), and 8-hydroxy-guanine levels.
Methods: Thirty-one adult female patients diagnosed with BPPV were included in this study. Patients with central pathologies and other peripheral causes of vertigo were excluded from the study. The patients were evaluated for oxidative stress during and after the BPPV attack with blood samples and spot urine tests. Depression, anxiety, and stress scale (DASS) questionnaire was used to evaluate emotional stress. A control group consisting of 30 age-matched healthy women was formed.
Results: Urinary oxidative stress values during the attack were significantly higher than the post-treatment group and the healthy control group (p<0.05). There was no significant difference between the urinary oxidative stress values of the BPPV group after treatment and the healthy control group (p>0.05). DASS scores were significantly higher during the attack and after the treatment compared to the healthy control group (p<0.05).
Conclusion: The increase in spot urinary 8-OHdG, 8-OHG, and 8-hydroxy-guanine levels can be used as a biomarker for oxidative stress in patients with BPPV. Furthermore, emotional stress can also trigger BPPV attacks by increasing oxidative stress.

Metformin, a widely used antidiabetic medication, has emerged as a promising broad-spectrum antiviral agent due to its ability to modulate cellular pathways essential for viral replication. By activating AMPK, metformin depletes cellular energy reserves that viruses rely on, effectively limiting the replication of pathogens such as influenza, HIV, SARS-CoV-2, HBV, and HCV. Its role in inhibiting the mTOR pathway, crucial for viral protein synthesis and reactivation, is particularly significant in managing infections caused by HIV, CMV, and EBV.

Multidrug-resistant tuberculosis (MDR-TB) poses a significant global health threat, especially when it involves the central nervous system (CNS). Tuberculous meningitis (TBM), a severe manifestation of TB, is linked to high mortality rates and long-term neurological complications, further exacerbated by drug resistance and immune evasion mechanisms employed by Mycobacterium tuberculosis (Mtb). Although pulmonary TB remains the primary focus of research, MDR-TBM introduces unique challenges in diagnosis, treatment, and patient outcomes.

With the increase of reactive oxygen species (ROS) production, cancer cells can avoid cell death and damage by up-regulating antioxidant programs. Therefore, it will be more effective to induce cell death by using targeted strategies to further improve ROS levels and drugs that inhibit antioxidant programs. Considering that dihydroartemisinin (DHA) can cause oxidative damage to protein, DNA, or lipids by producing excessive ROS, while, disulfiram (DSF) can inhibit glutathione (GSH) levels and achieve the therapeutic effect by inhibiting antioxidant system and amplifying oxidative stress, they were co-loaded onto the copper peroxide nanoparticles (CuO) coated with copper tannic acid (Cu-TA), to build a drug delivery system of CuO@Cu-TA@DSF/DHA nanoparticles (CCTDD NPs).

Dysregulated inflammation and oxidative stress are strongly implicated in the pathogenesis of inflammatory bowel disease. We have developed a novel therapeutic that targets inflammation and oxidative stress. It is comprised of microRNA-146a (miR146a)-loaded cerium oxide nanoparticles (CNPs) (CNP-miR146a).
