Results provide a meaningful signal of massage effect for primary care patients with chronic low back pain and call for further research in practice settings using pragmatic designs with control groups.
The role supporting electrolyte plays on the transport of the redox probe tris(bipyridine)ruthenium(II) chloride through the ion exchange polymer Nafion® was examined using cyclic voltammetry, rotating disk voltammetry, and spectroscopic techniques. Variations in both the extraction coefficient (κ) and the diffusion coefficient (D) were observed as the supporting electrolyte was varied. The anion of the supporting electrolyte was not found to influence mass transport, but the cation significantly influenced both extraction and diffusion of the redox probe within the polymer. A series of monovalent (Li+, Na+, K+, Rb+) and divalent (Mg2+, Ca2+, Ba2+, Zn2+) cations were studied, as well as the trivalent cation La3+.
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.
