The contribution of the human papillomavirus (HPV) to cancer is significant but not exclusive, as carcinogenesis involves complex mechanisms, notably oxidative stress. Oxidative stress and HPV can independently cause genome instability and DNA damage, contributing to tumorigenesis. Oxidative stress-induced DNA damage, especially double-strand breaks, aids in the integration of HPV into the host genome and promotes the overexpression of two viral proteins, E6 and E7. Lifestyle factors, including diet, smoking, alcohol, and psychological stress, along with genetic and epigenetic modifications, and viral oncoproteins may influence oxidative stress, impacting the progression of HPV-related cancers. This review highlights various mechanisms in oxidative-induced HPV-mediated carcinogenesis, including altered mitochondrial morphology and function leading to elevated ROS levels, modulation of antioxidant enzymes like Superoxide Dismutase (SOD), Glutathione (GSH), and Glutathione Peroxidase (GPx), induction of chronic inflammatory environments, and activation of specific cell signaling pathways like the Phosphoinositide 3-kinase, Protein kinase B, Mammalian target of rapamycin (PI3K/AKT/mTOR) and the Extracellular signal-regulated kinase (ERK) signaling pathway. The study highlights the significance of comprehending and controlling oxidative stress in preventing and treating cancer. We suggested that incorporating dietary antioxidants and targeting cancer cells through mechanisms involving ROS could be potential interventions to mitigate the impact of oxidative stress on HPV-related malignancies.

Sustained adrenergic overload in the heart causes maladaptive cardiac remodelling, which involves oxidative stress. Boldine (BOL) has antioxidant activity and represents a novel therapeutic approach. This study explored the cardioprotective role of BOL in adverse left ventricular remodelling induced by isoproterenol.

Atrial fibrillation (AF) is the most prevalent arrhythmia in clinical practice, and obesity serves as a significant risk factor for its development. The underlying mechanisms of obesity-related AF remain intricate and have yet to be fully elucidated. We have identified FPR2 as a potential hub gene involved in obesity-related AF through comprehensive analysis of four transcriptome datasets from AF patients and one transcriptome dataset from obese individuals, and its expression is up-regulated in both AF and obese individuals.

Chemotherapy-induced cardiotoxicity is a significant concern in cancer treatment, as certain chemotherapeutic agents can have adverse effects on the cardiovascular system. This can lead to a range of cardiac complications, including heart failure, arrhythmias, myocardial dysfunction, pericardial complications, and vascular toxicity. Strategies to mitigate chemotherapy-induced cardiotoxicity may include the use of cardioprotective agents (e.

Background: Saliva contains a variety of biochemical compounds, including antioxidants, and serves as the body's first line of defense against oxidative stress caused by free radicals. The aim of this study was to investigate the effects of dental treatments on salivary oxidative stress biomarkers in children aged 3-5 years with severe early childhood caries (S-ECC) compared to children without caries.
Method: This study was conducted on 20 children aged 3-5 years with severe early childhood caries (S-ECC) and 20 children without caries.

Metabolic syndrome (MetS) is driven by a complex interplay of genetic, lifestyle, and dietary factors, leading to weight gain, insulin resistance, dyslipidemia, and chronic inflammation. Gut microbiota dysbiosis has been recently recognized as a key contributor to MetS, leading to advancements in gut microbiome-based interventions to improve health outcomes. Considering the unique challenges associated with the use of pre/probiotics, short-chain fatty acids (SCFA), also known as postbiotics, have emerged as promising therapeutic agents due to their role in modulating host metabolism and physiology.
