Vitamin C megadosage Based on that study, the American Burn Association (ABA) considers high-dose ascorbic acid an option to be considered for adjuvant therapy in addition to the more accepted standard treatments. Atrial fibrillation (AF) is a common cardiac rhythm disturbance and it is associated with oxidative stress. Four meta-analyses have concluded that there is strong evidence that 1-2 g/day of vitamin C before and after cardiac operations can decrease the risk of post-operative AF. However, five randomized studies did not find benefit in the USA, so that the benefit was restricted to less wealthy countries. Exercise-induced bronchoconstriction (EIB) indicates acute narrowing of
Nucleic acid structure determination short lived in solution they need to be generated. This can be done using HO, ascorbic acid, and Fe(II)-EDTA complex which is attached to the backbone through EDTA. The Fe(II) along with ascorbic acid generates hydroxyl radicals which then can react with the nucleic acid molecules. Hydroxyl radical probing is often used in conjunction with chemical probing of nucleic acid molecules that are thought to associate with proteins, this is due to the modification done by hydroxyl radicals. Hydroxyl radicals attack the ribose/deoxyribose ring and this results in breaking of the phosphate backbone, which is independent of secondary structure, as
