Antioxidant Activity of gamma-Oryzanol: A Complex Network of Interactions
(Mdpi Ag, 2016-08-01)
gamma-oryzanol (Orz), a steryl ferulate extracted from rice bran layer, exerts a wide spectrum of biological activities. In addition to its antioxidant activity, Orz is often associated with cholesterol-lowering, ...
Local atomic structure of lanthanide complexes in cubic ordered mesoporous silica
(Elsevier B.V., 2013-05-25)
The aim of this work was to analyze the local atomic environment around lanthanide atoms anchored inside silica matrices by means of X-ray absorption spectroscopy (XAS). Europium and cerium complexes were incorporated in ...
Thermal and morphological study of chitosan metal complexes
(Springer, 2017-07-01)
The synthesis of chitosan Schiff bases, N-benzylidene chitosan (CTB), 4-dimethylamino-benzylidene chitosan (CTDB) and 4-nitro-benzylidene chitosan (CTNB), and their interaction with Cu2+, Zn2+ and Ni2+ were studied. The ...
Characterization of the Interactions between Endocrine Disruptors and Aquatic Humic Substances from Tropical Rivers
(Soc Brasileira Quimica, 2011-01-01)
Interactions between two endocrine disruptors (ED) and aquatic humic substances (AHS) from tropical rivers were studied using an ultrafiltration system equipped with a 1 kDa cut-off cellulose membrane to separate free ED ...
Interaction Study Between Humin and Phosphate: Possible Environmental Remediation for Domestic Wastewater
(2017-01-01)
The increase in demand for food due to the rapid population growth in recent years has raised the use of fertilizers, particularly phosphate salts. This fact has contributed to the excess amount of phosphorus species in ...

Redox-active complexes formed during the interaction between glutathione and mercury and/or copper ions
(2010)
Prompted by the recently reported capacity of the physiologically occurring Cu(I)-[glutathione]2 complex (Cu(I)-[GSH)]2) to reduce oxygen, the effect of various GSH-binding metals (Co2+, Cd2+, Zn2+, Pb2+, Al3+, Hg2+ and ...
Contribution of soil organic carbon to the ion exchange capacity of tropical soils
(HAWORTH PRESS INC, 2008)
Highly weathered soils represent about 3 billion ha of the tropical region. Oxisols represent about 60% of the Brazilian territory (more than 5 million km 2), in areas of great agricultural importance. Soil organic carbon ...
