  • A Soy Protein-Based Film Based on Chemical Treatment and Microcrystalline Cellulose Reinforcement Obtained from Corn Husk Byproducts.: This research explores the development of a soy protein-based film reinforced with microcrystalline cellulose derived from corn husk byproducts, treated chemically with sodium sulfite. The resulting film exhibited enhanced mechanical properties, making it a viable option for biodegradable packaging (Zhang et al., 2024) (Zhang et al., 2024).

  • Modelling Energy-Harvesting Processes in Primitive Cells: Proton Transport Across Bilayers Driven by the Oxidation of Sulfite.: This article models the energy-harvesting processes in primitive cells, focusing on proton transport across bilayers driven by sulfite oxidation. The findings contribute to the understanding of early cellular bioenergetics and the role of sulfite in these processes (Paula et al., 2024) (Paula et al., 2024).

Nitrone spin traps such as 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) are commonly used for free radical detection. Though proven examples are rare, artifact formation must be considered. For example, the Forrester-Hepburn mechanism yields the same radical adduct as that formed by genuine radical

Carbon monoxide-releasing molecules (CO-RMs) emulate the beneficial (e.g., anti-inflammatory) effects of CO in biology. CO release from CO-RMs is routinely determined in the presence of reduced deoxy-myoglobin by measuring the formation of carboxy-myoglobin (Mb-CO). Previous studies have highlighted discrepancies between
