7910657-7	1994	The delay in the restoration of the sodium gradient may in turn prolong the neuronal exposure to toxic [Ca2+]i values, due to the decrease in the efficiency of the Na+/Ca2+ exchanger to extrude calcium.	Sodium	36-42	nascent polypeptide associated complex subunit alpha 2	Homo sapiens	164-171	
1438878-11	1992	Blockade of the response in the absence of external sodium suggests that Na+/Ca2+ exchanger participates in this response.	Sodium	52-58	nascent polypeptide associated complex subunit alpha 2	Homo sapiens	73-80
