说明

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).
