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.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Teaching the concepts of oxidation and reduction contextualized in the study of corrosion
Revista Eureka sobre Enseñanza y Divulgación de las Ciencias, 2013 The contextualization of chemistry is of great importance to our society as it allows to bring this science to students of secondary education thus facilitating the learning process, so that students can identify and explain the phenomena that occur ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

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 ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
