Measuring vitamin B-12 bioavailability with [13C]-cyanocobalamin in humans

For patients with significant injury histories, the combination is almost always more appropriate than either peptide alone

Research on this specific application is limited

Consistent with these findings, recent reviews have identified recurring antiviral mechanisms among carbon-dot-based nanomaterials, including viral surface protein interference and redox-mediated viral inactivation, however, they also emphasis the lack of standardised synthesis, limited in vivo validation, and incomplete toxicological characterisation, which collectively constraint clinical translation [131]
