The intensity of lipid peroxidation in the homogenates and mitochondria of the liver, heart and skeletal muscle of hypokinetic rats was measured. The primary products of lipid peroxidation, i. e., diene conjugates, were accumulated in all tissues on hypokinesia days 3, 15, and 30. The content of the final product--malonic dialdehyde--in the mitochondria increased on hypokinesia days 15 and 30. The low level of NADPH--and ascorbate-dependent lipid peroxidation in the mitochondria at early stages of hypokinesia (up to 15 days) and diene conjugates in homogenates on hypokinesia day 7 can be attributed to an activation of the protective systems of the organism against the immobilization stress. It is suggested that at early stages of hypokinesia the process of lipid peroxidation, or to be more precise lipid hydroperoxidation can be blocked.

Multiple sclerosis (MS) is a chronic autoimmune disorder marked by neuroinflammation, demyelination, and neuronal damage. Recent advancements highlight a novel interaction between iron-dependent cell death, known as ferroptosis, and gut microbiota, which may significantly influences the pathophysiology of MS. Ferroptosis, driven by lipid peroxidation and tightly linked to iron metabolism, is a pivotal contributor to the oxidative stress observed in MS.

Today, accumulating evidence highlights the impact of oxidative stress (OS) on semen quality. It is considered to be a key factor contributing to the decline in male fertility. OS is detected in 30-80% of men with infertility, highlighting its strong association with impaired reproductive function and with clinical outcomes following the use of assisted reproductive technologies.

Background/objectives: The pathogenesis of metabolic dysfunction-associated steatohepatitis (MASH) is closely associated with increased oxidative stress and lipid peroxidation. Coenzyme Q (CoQ) and selenium (Se) are well-established antioxidants with protective effects against oxidative damage. This study aimed to investigate the effects of CoQ and Se in ameliorating MASH induced by a methionine choline-deficient (MCD) diet in mice.
