Serum lipid peroxides, lipids, blood pressure, body mass index, and dietary intake in 190 urban men were compared with 190 age-matched rural men. Significantly higher levels of lipid peroxides, serum cholesterol, low-density lipoprotein cholesterol, and triglycerides were seen in urban men, compared with rural men. In rural men, serum lipid peroxides were related negatively to age; the same was observed in the 70 + y age group in the urban population. All the lipid constituents were related positively to age in both populations. There were statistically significant correlations between lipid peroxides and serum cholesterol and triglycerides in the urban men. The marked elevation of lipid peroxides and lipids in urban men may be the result of urbanization, including exposure to environmental pollutants.

Ferroptosis, distinct from apoptosis, is primarily characterized by the accumulation of iron-dependent lipid peroxides (LPO) and reactive oxygen species (ROS). This process plays a pivotal role in the pathophysiology of various diseases and has recently emerged as a promising therapeutic strategy in oncology, garnering significant attention. Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), serve as crucial regulators in numerous biological processes, particularly in cancer initiation and progression.

The progression of tumors has been demonstrated to have a strong correlation with ferroptosis. Bis(4-hydroxy-3,5-dimethylphenyl) sulfone (TMBPS) has been shown to effectively inhibit the proliferation of hepatocellular carcinoma (HCC), but its underlying mechanism is not clear. In this study, ferrostatin-1 (Fer-1) was employed to explore whether the death of HCC cells caused by TMBPS is related to ferroptosis.

Thyroid hormones (TH) are major regulators of cell differentiation, growth, and metabolic rate. TH synthesis in the thyroid gland requires high amounts of HO to oxidize iodide for the iodination of thyroglobulin (TG). Retinol Saturase (RetSat) is an oxidoreductase implicated in dihydroretinol formation and cellular sensitivity toward peroxides and ferroptosis.

As the central organ of metabolism, the liver plays a pivotal role in the regulation of the synthesis and metabolism of various nutrients within the body. Ferroptosis, as a newly discovered type of programmed cell death caused by the accumulation of iron-dependent lipid peroxides, is involved in the physiological and pathological processes of a variety of acute and chronic liver diseases. Ferroptosis can accelerate the pathogenetic process of acute liver injury, metabolic associated fatty liver disease, alcoholic liver disease, viral hepatitis, and autoimmune hepatitis; while it can slower disease progression in advanced liver fibrosis and hepatocellular carcinoma.

This study evaluates the impact of various processing steps in the human milk (HM) donation chain on nutritional composition and oxidative biomarkers, specifically focusing on triacylglycerols, glucose, polyphenols, and lipid peroxides. A total of 68 HM samples were collected from the Human Milk Bank of Córdoba (Argentina) between 2022 and 2023. The effects of storage and pasteurization using the Holder method were assessed.
