Abstract: The present disclosure provides a method for improving bioavailability of an NAD+ derivative. The method improves the bioavailability of the NAD+derivative by arranging a CD38 inhibitor and the NAD+ derivative in a same preparation, and controlling the CD38 inhibitor to release first rapidly, and then the NAD+ derivative releases after the CD38 inhibitor has taken effect, thereby increasing the level of NAD+ in vivo.

Abstract: An interaction method is provided, which includes: generating a target conference code matching a target language, and sending the target conference code to the target user. The target language is determined according to a target user, and the target conference code indicates a multimedia conference.

Abstract: Disclosed in embodiments of the present disclosure are a communication method and apparatus, and an electronic device. A specific implementation of the method comprises: in response to a call initiation operation of a multimedia conference, determining a candidate object of the multimedia conference according to an object targeted by the call initiation operation; and displaying, on a multimedia conference interface of the multimedia conference, call state information for the candidate object.

Abstract: A method of fabricating a conductor includes preparing an aramid nanofiber solution in which a matrix of aramid nanofibers is dispersed, preparing a dispersion of copper nanoparticles, each copper nanoparticle of the dispersion of cooper nanoparticles having an organic capping ligand attached to the copper nanoparticle, and incorporating copper nanoparticles of the dispersion of copper nanoparticles into the matrix of aramid nanofibers such that each incorporated copper nanoparticle is bonded to a respective aramid nanofiber of the matrix of aramid nanofibers via the organic capping ligand to which the copper nanoparticle is attached. The organic capping ligand may include a mercaptocarboxyiic acid.
