Iron buffer system in the water column and partitioning in the sediments of the naturally acidic Lake Caviahue, Neuquén, Argentina
(Elsevier Science, 2016-05)
Sedimentary iron partitioning was studied for five sediment strata (16 cm depth) at three sampling sites of the naturally-occurring acidic Lake Caviahue (Patagonia, Argentina). Additionally, water column iron was modeled ...
Mathematical modeling of the dynamic storage of iron in ferritin
(BIOMED CENTRAL LTD, 2010-11-03)
Background: Iron is essential for the maintenance of basic cellular processes. In the regulation of its cellular levels,
ferritin acts as the main intracellular iron storage protein. In this work we present a mathematical ...
Construction and application of an electrochemical sensor for paracetamol determination based on iron tetrapyridinoporphyrazine as a biomimetic catalyst of P450 enzyme
(Soc Brasileira Quimica, 2008-01-01)
This work describes the construction and application of a biomimetic sensor for paracetamol determination in different samples. The sensor was prepared by modifying a glassy carbon electrode surface with a Nafion (R) ...

Lipid peroxidation, antioxidant enzymes and glutathione levels in human erythrocytes exposed to colloidal iron hydroxide in vitro
(Associação Brasileira de Divulgação Científica (ABRADIC), 1999-06-01)
The free form of the iron ion is one of the strongest oxidizing agents in the cellular environment. The effect of iron at different concentrations (0, 1, 5, 10, 50, and 100 µM Fe3+) on the normal human red blood cell (RBC) ...

Development and application of a highly selective biomimetic sensor for detection of captopril, an important ally in hypertension control
(2010-09-01)
A biomimetic sensor is proposed as a promising new analytical method for determination of captopril in different classes of samples. The sensor was prepared by modifying a carbon paste electrode with iron (II) phthalocyanine ...
