FK506 accelerated functional recovery of facial nerve function after crush injury. Neuroregeneration was inhibited by FKBP-52 antibody in the rat midface but not the upper face. FK506 may be a viable adjuvant treatment for facial nerve neurapraxic injury.
The surface interactions of the thermodynamically stable oxides of the firstrow transition metals with hydrazine, N,H,, have been assessed by X-ray photoelectron spectroscopy (X.P.S.), and the observed reactivity explained on the basis of the oxides' thermodynamic and acid-base properties. Microgravimetry, transmission electron microscopy (TEM) and X.P.S. studies of copper(1r) oxide (CuO) reduction by hydrazine indicate morphological changes associated with enhanced reactivity. Comparison of hydrazine and hydrogen reduction treatments shows that CuO reduction by hydrazine is more spontaneous and provides a greater increase in surface area than does hydrogen at similar reaction conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
