11103842-8	2000	The highest activity of U-NAG was observed in the exposed workers with the lower concentrations of selenium in whole blood.	Selenium	99-107	N-acetyl-alpha-glucosaminidase	Homo sapiens	26-29	
31505350-7	2020	U-NAG levels were significantly negatively associated with the interaction between Cd and Se (B: -0.511, 95% CI: -0.886, -0.136).	Selenium	90-92	N-acetyl-alpha-glucosaminidase	Homo sapiens	2-5	
16804628-7	2006	The serum selenium concentration and serum glutathione peroxidase activity were associated with the activity of N-acetyl-beta-D-glucosaminidase in urine (U-NAG).	Selenium	10-18	N-acetyl-alpha-glucosaminidase	Homo sapiens	156-159	
16804628-8	2006	The results indicate that having higher glutathione peroxidase activity or a higher serum selenium concentration results in a lower excretion of U-NAG.	Selenium	90-98	N-acetyl-alpha-glucosaminidase	Homo sapiens	147-150	
16804628-10	2006	Apparently the well-known association between U-NAG and age could only be found for the participants with a lower selenium status.	Selenium	114-122	N-acetyl-alpha-glucosaminidase	Homo sapiens	48-51	
16804628-12	2006	Selenium status has a substantial impact on U-NAG activity and should be considered in studies of U-NAG excretion.	Selenium	0-8	N-acetyl-alpha-glucosaminidase	Homo sapiens	46-49	
16804628-12	2006	Selenium status has a substantial impact on U-NAG activity and should be considered in studies of U-NAG excretion.	Selenium	0-8	N-acetyl-alpha-glucosaminidase	Homo sapiens	100-103
