pioglitazone (pg) is one of thiazolidinediones used for the treatment of type ii diabetes mellitus. some reports of its hepatotoxicity exist, but the mechanism of its hepatotoxicity is not well known. in the present study, the protective effect of some atp suppliers are investigated against mitochondrial toxicity of pg in isolated rat mitochondria. mitochondrial viability was investigated by mt...

background: friedreich ataxia (frda) is an autosomal recessive disorder caused by guanine-adenine-adenine (gaa) triplet expansions in the fxn gene. its product, frataxin, which severely reduces in frda patients, leads to oxidative damage in mitochondria. the purpose of this study was to evaluate the triple nucleotide repeated expansions in iranian frda patients and to elucidate distinguishable ...

background: the mitochondria are an important source of adenosine triphosphate (atp) production in pre-implantation embryo. therefore, the objective of this study was to investigate the effect of vitrification and in vitro culture of mouse embryos on their mitochondrial distribution and atp content. methods: the embryos at 2-pn, 4-cell and blastocyst stages were collected from the oviduct of st...
