Polymorphism of Glutathione S-Transferase (GST) Variants and Its Effect on Distribution of Urinary Arsenic Species in People Exposed to Low Inorganic Arsenic in Tap Water: An Exploratory Study
(Taylor & Francis, 2013-07-09)
Glutathione S-tranferases (GST) are multigenic enzymes that have been associated with
arsenic metabolism. The objective of this study was to evaluate the relationship between polymorphic
variants of GST and urinary ...
Silicates characterization as potential bacteriocin-carriers
(Elsevier, 2010-01)
Two different silicates, zeosil and expanded perlite, were characterized as potential carriers of a bacteriocin with anti-Listeria monocytogenes activity, produced by Enterococcus faecium CRL1385. Specific surface areas ...
