Ominously, my usually responsive agent went silent for weeks.
The drug carriers contain stimuli-responsive agents, which are stable before they reach the target location, but enable rapid drug release that is triggered by the generation of CO2 bubbles, which are chemically inert, under certain stimuli.
Even though the identities of the primary UV-responsive agents are unknown, both keratinocytes and melanocytes produce various substances that enhance melanogenesis upon UV stimulation [ 6, 12, 13].
Efforts have been made to design MRI-responsive agents for the following biologically relevant metal ions: Ca2+ (Atanasijevic et al., 2006); Zn2+ (Esqueda et al., 2009); Mg2+ (Hifumi et al., 2007); Fe2+ (Livramento et al., 2005); Cu2+ (Que and Chang, 2006); Cu+ (Que et al., 2012); and K+ (Hifumi et al., 2007).
Its core function is to act as a wise, well-informed, responsive and responsible agent of the Scottish people in identifying that excellence, and in providing funds to support it.
Phosphoprotein DAB2 is a mitogen-responsive agent, acting as tumor suppressor in normal ovaian epithelial cells and down-regulation of this gene modulates the TGF-β signalling pathway [ 67].
We believe that the proposed technique can be applied to different stimuli responsive miniaturized agents, allowing the user to estimate the full configuration of complex agents from visual marker-less observations.
"Responsive" EV agents are the ones that respond rationally to the virtual pricing signals, whereas "Unresponsive" EV agents define their charging schedule regardless the virtual cost.
The results highlighted the adaptive behaviour of "Responsive" EV agents and proved their ability to charge preferentially from renewable energy sources.
Responsive contrast agents are key to furthering the diagnostic potential of MRI, both to provide anatomical information and to discern biochemical activity.
