8328834-5	1993	Absorption of free and food-bound 57Co-vitamin B12 was evaluated separately using 24-hour urinary excretion.	Cobalt-57	34-38	NADH:ubiquinone oxidoreductase subunit B3	Homo sapiens	47-50	
16096589-0	2005	Estimated radiation dose to breast feeding infant following maternal administration of 57Co labelled to vitamin B12.	Cobalt-57	87-91	NADH:ubiquinone oxidoreductase subunit B3	Homo sapiens	112-115	
2239025-2	1990	Schilling test was performed with 37 kBq (1 microCi) of 57Co-labelled vitamin B12 as an analysis of urinary radioactivity.	Cobalt-57	56-60	NADH:ubiquinone oxidoreductase subunit B3	Homo sapiens	78-81	
6831844-3	1983	A non-absorbable tracer, 51Cr-chromic chloride, was administered firstly with 58Co-labelled vitamin B12 and then three hours later with 57Co-labelled vitamin B12 and then three hours later with 57Co-labelled vitamin B12 plus 50 mg hog intrinsic factor which normalises B12 malabsorption in patients with pernicious anaemia.
