Redox transformations of iron at extremely low pH: fundamental and applied aspects
Frontiers in Microbiology, 2012 Many different species of acidophilic prokaryotes, widely distributed within the domains Bacteria and Archaea, can catalyze the dissimilatory oxidation of ferrous iron or reduction of ferric iron, or can do both.

Post-Electrophoretic Identification of Oxidized Proteins
Biological Procedures Online, 2000 The oxidative modification of proteins has been shown to play a major role in a number of human diseases. However, the ability to identify specific proteins that are most susceptible to oxidative modifications is difficult.

Anaerobic methane oxidation coupled to manganese reduction by members of the Methanoperedenaceae
The ISME Journal, 2020 Anaerobic oxidation of methane (AOM) is a major biological process that reduces global methane emission to the atmosphere. Anaerobic methanotrophic archaea (ANME) mediate this process through the coupling of methane oxidation to different electron ...

Indirect Spectrophotometric Determination of Niclosamide in Pharmaceutical Preparations [PDF]
مجلة التربية والعلم, 2018 A simple and sensitive indirect spectrophotometric method is developed for the determination of niclosamide in pharmaceutical preparations. The method is based on the oxidation of reduced form of niclosamide with iron ( III ) in acidic medium, then the ...

Oxidation-reduction potential as a new marker for oxidative stress: Correlation to male infertility
Investigative and Clinical Urology, 2017 Male infertility affects men worldwide. Oxidative stress (OS), characterized by an overabundance of reactive oxygen species (ROS) or a deficiency of antioxidants, is one of the major causes of male infertility.

Methane oxidation linked to chlorite dismutation.
Frontiers in Microbiology, 2014 We examined the potential for CH4 oxidation to be coupled with oxygen derived from the dissimilatory reduction of perchlorate, chlorate or via chlorite (ClO2-) dismutation.
