Multiple Sclerosis (MS) is a neurodegenerative and autoimmune disease that it’s molecular etiology and factors involving in its progression remains unknown. In this study for evaluation effect of mercuric on progression of MS we investigated the additive effect of mercuric sulfide on the brain mitochondrial dysfunction in experimental autoimmune encephalomyelitis (EAE) model of MS in C57BL/6 mi...

Cultures of mutant cni-1, a chromosomal mutant of Neurospora crassa, undergo a marked change in respiratory properties as the age of the culture increases. Early log phase cultures have a high level of respiration that is insensitive to inhibition by cyanide or antimycin A. Late log and stationary phase cultures have reduced rates of respiration. A high percentage of this respiration is inhibit...

We sequenced 1077 bp of the mitochondrial cytochrome b gene and 511 bp of the nuclear Apolipoprotein B gene in bicoloured shrew (Crocidura leucodon, Soricidae) populations ranging from France to Georgia. The aims of the study were to identify the main genetic clades within this species and the influence of Pleistocene climatic variations on the respective clades. The mitochondrial analyses reve...

Initial amplification and sequencing of a 366-bp fragment of the cytochrome b gene by a conserved primer pair (MVZ 03 and MVZ 04) revealed a nonfunctional copy of the gene with two deletions (one of which is 17 bp in length and the other of which is 3 bp in length) in Chroeomys jelskii, a South American akodontine rodent. By means of an alternative primer to MVZ 03--namely, MVZ 05--from the reg...

The number of species salamanders the genus Onychodactylus in Japan has increased from one to six nominal over past decade, by taxonomic studies based not only on morphological but also molecular phylogenetic data. However, presence an additional cryptic been suggested a series previous studies. Here, we describe new species, pyrrhonotus sp. nov., Kinki, Chubu and Hokuriku Districts central Hon...

In a prior study, we identified seven clinical isolates of an Aspergillus sp. that were slow to sporulate in multiple media and demonstrated decreased in vitro susceptibilities to multiple antifungals, including amphotericin B, itraconazole, voriconazole, and caspofungin. These isolates were initially considered to be variants of Aspergillus fumigatus because of differences in mitochondrial cyt...

Nuclear mutants of Saccharomyces cerevisiae assigned to complementation group G34 are respiratory-deficient and lack cytochrome oxidase activity and the characteristic spectral peaks of cytochromes a and a(3). The corresponding gene was cloned by complementation, sequenced, and identified as reading frame YGR062C on chromosome VII. This gene was named COX18. The COX18 gene product is a polypept...

In this research, we investigated the cytotoxic mechanisms of one of the widely used pharmaceuticals that are regularly associated with the adverse effects on the liver, sometimes leading to acute liver failure, diclofenac. Diclofenac liver cytotoxicity was associated with reactive oxygen species (ROS) formation and lipid peroxidation which were inhibited by antioxidants and ROS scavengers, fer...

Complete mitochondrial cytochrome b gene sequences were determined from 12 species of the Australo-Papuan birds-of-paradise (Paradisaeidae) representing 9 genera. Phylogenetic analysis of these and 5 previously published sequences reveals a radiation of the main paradisaeinine lineages that took place over a relatively short evolutionary time scale. The core paradisaeinines are resolved as the ...
