WT-MSCs act through paracrine vs. direct mechanisms.
In this sense, there is no loss of generality in restricting attention to direct mechanisms.
Direct mechanisms suggested are the ionization and the Cherenkov effect caused by highly charged particles.
Much of the literature on mechanism design and implementation uses the revelation principle to restrict attention to direct mechanisms.
That is, in mechanism design problems with multiple agents the use of direct mechanisms may be suboptimal.
Downward migration of particles originating in the combustion residues is suggested to be the direct mechanisms of the metal enrichments.
Direct mechanisms of TRPA1 activation have been described, although the precise mechanisms of sensitization/desensitization by which the inflammatory mediators potentiate the channel activity remain poorly understood.
Herein, to address this question, direct mechanisms of raw SWNHs on the growth, proliferation, and apoptosis of mice microglia cell lines were studied.
Taken together, these findings provide strong evidence that injury to the endothelial barrier is more severe in indirect mechanisms of acute lung injury than in direct mechanisms.
Historically, democracy first took hold in the ancient city states of Mesopotamia and Greece through direct mechanisms such as sortition (Keane 2009).
The results show that visitors prefer direct mechanisms for obtaining information about the exhibits, such as text on a panel or videos on a screen.
