This study investigated the way in which feeding rats with two fat sources (olive or sunflower oils) affected electron-transport components and function of mitotic (liver) and postmitotic (heart and skeletal muscle) tissues during ageing. Rats adapted the mitochondrial-membrane-lipid profile to dietary fat throughout the study, suggesting that the benefits to eat either of the two fats might be...

Mitochondrial DNA (mtDNA) is the most popular marker of molecular diversity in animals, primarily because of its elevated mutation rate. After >20 years of intensive usage, the extent of mitochondrial evolutionary rate variations across species, their practical consequences on sequence analysis methods, and the ultimate reasons for mtDNA hypermutability are still largely unresolved issues. Usin...

Arsenic exposure mainly through food and water has been shown to be associated with increased incidence of numerous cancers and non-cancer harmful health. It is also used in cancer chemotherapy and treatment of several cancer types due to its apoptogenic effects in the various cancer and normal cell lines. We have already reported that liver is the storage site and important target organ in As ...

The recent demonstration that certain mitochondrial subunits of cytochrome oxidase (CO) are regulated by neuronal activity has stimulated interest in the molecular processes that coordinate nuclear and mitochondrial gene expression following synaptic stimulation. We have studied the constitutive expression and activity-guided regulation of cytochrome b (cyt b), a gene that is encoded by mitocho...

sergentomyia sintoni is the natural vector of sauroleishmania species of lizards. this sandfly isabundance in and around the burrows of great gerbils. s. sintoni was collected from peridomestic animalshelters, inside and around houses and also from the nearby burrows of the gerbil reservoir hosts,rhombomys opimus, in several provinces of iran. mitochondrial cytochrome b (cyt b) of sandflies, wh...
