Introduction: The mitochondrial defects in Friedreich ataxia (FRDA) have been reported in many researches. Friedreich ataxia is an autosomal recessive neurodegenerative disorder caused by decreased expression of the Frataxin protein. Frataxin deficiency leads to excessive free radical production and dysfunction of respiratory chain complexes. Mitochondrial DNA (mtDNA) could be considered as a c...
in many models of programmed cell death, the mitochondrial protein aif translocates to the nucleus, where it induces the chromatin condensation and dna degradation. however, today it is well established that this flavoprotein is bifunctional. in addition to its lethal function in the nucleus of dying cells, aif plays a vital bioenergetic role in healthy ones by regulating mainly the activity of...
Highlights • Reconstruction of mitochondrial protein import and cofactor metabolism in the model eukaryote Saccharomyces cerevisiae Quantification proton motive force shows significant energy cost metabolite transport Protein activity depends on growth rate respiratory iron-sulfur cluster requirements show dependence
Introduction: Alzheimer’s disease is a progressive neurodegenerative disorder, characterized by impairment of memory and changes in behavior and personality. Recent evidence suggests that mitochondrial channels play important roles in memory disorders. Accordingly, the biophysical properties of a single potassium channel were investigated in the brain mitochondrial inner membrane of rat with...
A Thai plant Clitoria macrophylla Wall. was claimed to possess some pharmacological activities. The phytochemical studies reported a rotenoid compound, 6-deoxyclitoriacetal, which exhibits the cytotoxic effect in several cell line experiments. This report was to study the effect of 6-deoxyclitoriacetal on rat liver mitochondria, which may associated to its cytotoxic phenomena. Mitochondrial sus...

results the results reveal that pq can decrease mitochondrial viability, deplete gsh content, increase mitochondrial ros formation, and enhance lpo and mitochondrial membrane damage. the pretreatment of mitochondria with ng has the ability to reduce the toxic effects of pq in isolated mitochondria. background paraquat (pq) is a dipyridyl herbicide that sustains damage due to redox cycling. an i...
BACKGROUND Fluorescent-magnetic-biotargeting multifunctional nanospheres are likely to find important applications in bioanalysis, biomedicine, and clinical diagnosis. We have been developing such multifunctional nanospheres for biomedical applications. METHODS We covalently coupled avidin onto the surfaces of fluorescent-magnetic bifunctional nanospheres to construct fluorescent-magnetic-bio...
Resource misallocation can lower aggregate total factor productivity (TFP). We use microdata on manufacturing establishments to quantify the potential extent of misallocation in China and India versus the United States. We measure sizable gaps in marginal products of labor and capital across plants within narrowly defined industries in China and India compared with the United States. When capit...
