Cholesterol oxidized products in foods: potential health hazards and the role of antioxidants in prevention

open access: yesGrasas y Aceites, 2004
Cholesterol is a molecule with a double bond in its structure, and therefore it is susceptible to oxidation leading to the formation of oxysterols. These oxidation products are found in many commonly consumed foods and are formed during their manufacture

Mathematical Analysis of FLASH Effect Models Based on Theoretical Hypotheses [PDF]

open access: yesPhys. Med. Biol. 2024. 69: 245005, 2023
Clinical applications of FLASH radiotherapy require formulas to describe how the FLASH radiation features and other related factors determine the FLASH effect. Mathematical analysis of the models can connect the theoretical hypotheses with the radiobiological effect, which provides the foundation for establishing clinical application models.
