Popis

Application

• Nitric oxide pros and cons: The role of L-arginine, a nitric oxide precursor, and idebenone, a coenzyme-Q analogue in ameliorating cerebral hypoxia in rat.: This study discusses the dual roles of nitric oxide and sodium nitrate′s contribution to ameliorating cerebral hypoxia, providing insights into its neurological applications (Abdel Baky NA et al., 2010).


• Use of experimental design methodology for the development of new magnetic siRNA nanovectors (MSN).: This study details the innovative application of sodium nitrate in the development of magnetic siRNA nanovectors, highlighting its role in enhancing delivery systems (David S et al., 2013).
