Antioxidant Activity and Oxidative Stress

Oxidative stress and inflammation play central roles in the immunopathogenesis of COVID‐19. In this study, we investigated whether circulating carotenoids, retinol, and vitamin E metabolites can distinguish COVID‐19 patients from healthy controls and discriminate disease severity. We analyzed 44 hospitalized COVID‐19…

The development and progression of breast cancer (BC) are influenced by genetic, hormonal, and metabolic factors, as well as by signals within the tumor microenvironment. A review of studies on BC biology and treatment outcomes was undertaken. The studies were experimental, translational, and clinical, and were indexe…

Background: Omega-3 fatty acids may be relevant to mental health, but evidence among university students remains limited. This small exploratory cross-sectional study examined associations between estimated dietary omega-3 intake and anxiety and depressive symptoms among university students in the UK. Methods: Data we…

Background: Lipoprotein metabolism, inflammation, and oxidative stress (OS) play interconnected roles in the pathogenesis of acute coronary syndrome (ACS). However, the relationship between oxidative stress biomarkers and coronary artery disease (CAD) complexity, particularly as assessed by the SYNTAX II score, remain…

Background and Aim Apoptosis is one of the programmed cell death pathways. Cysteine protease, Caspase 8 ( CASP8 ), starts apoptosis signaling through the extrinsic apoptotic pathway. Oxidatively modified low-density lipoprotein (ox-LDL) activates the apoptosis in vascular endothelial cells (VECs). Ox-LDL is a crucial…

Abstract The binding interactions of (E)-2,4-di-tert-butyl-6-(((4-phenoxyphenyl)imino)methyl)phenol (TBIP) with bovine serum albumin (BSA), human serum albumin (HSA), and calf thymus DNA (CT-DNA) were investigated using square-wave voltammetry (SWV) at pH 7.40, as well as molecular docking (MD) application. In additio…

Urologic malignancies (UMs), including prostate cancer (PCa), bladder cancer (BCa), renal cell carcinoma (RCC), and testicular germ cell tumors (TGCT), are governed by interconnected molecular pathways that regulate proliferation, angiogenesis, metabolism, invasion, immune escape, and treatment resistance. Key pathway…

Growing tomatoes in season and organically are an important factor in terms of carrying higher levels of antioxidant molecules. This study aimed to demonstrate the protective effect of extracts obtained from naturally grown tomatoes, which are widely used as food, against oxidative damage caused by hydrogen peroxide o…
