The lesser Japanese mole, Mogera imaizumii, recognized by Motokawa and Abe (1996), occurs in eastern Honshu, western Honshu and Shikoku. Mitochondrial and nuclear DNA were analyzed for mole samples from eastern Honshu to elucidate intraspecific differentiation. Analyses of sequences of the mitochondrial cytochrome b gene (Cytb) and of a restriction fragment length polymorphism of the nuclear 28...
DNA sequences for the mitochondrial cytochrome b gene were determined for 13 species of sharks. Rates and patterns of amino acid replacement are compared for sharks and mammals. Absolute rates of cytochrome b evolution are six times slower in sharks than in mammals. Bivariate plots of the number of nonsynonymous and silent transversions are indistinguishable in the two groups, however, suggesti...
Mitochondrial oxidative phosphorylation (OXPHOS) is responsible for generating the majority of cellular ATP. Complex III (ubiquinol-cytochrome c oxidoreductase) is the third of five OXPHOS complexes. Complex III assembly relies on the coordinated expression of the mitochondrial and nuclear genomes, with 10 subunits encoded by nuclear DNA and one by mitochondrial DNA (mtDNA). Complex III deficie...
the spinocerebellar ataxias (sca) comprise a heterogeneous group of severe late-onset neurodegenerative diseases that are promoted by the expansion of a tandem-arrayed dna sequence that modifies the primary structure of the protein. method: genomic dna of 20 patients with scas was extracted from peripheral blood and screened for deletions in mitochondrial dna (mtdna). sequencing of trna(leu), t...
how to cite this article: khatami m, heidari mm, mansouri r, mousavi f. the polg polyglutamine tract variants in iranian patients with multiple sclerosis. iran j child neurol. 2015 winter; 9(1):37-41. abstract objective multiple sclerosis (ms) is a common disease of the central nervous system. the interaction between inflammatory and neurodegenerative processes typically results in irregular ne...
Peacock bass or the cichlids are known locally as top predator fishes which invasive in Malaysia freshwater system. Detection probabilities for these typically low, especially using conventional capture-survey method due to fish’s behaviour of hiding beneath water’s surface. Hence, environmental DNA (eDNA) monitoring is a relatively new approach that can be used assess distribution fishes. Here...
DNA was extracted from an 11,700-year-old rodent midden from the Atacama Desert, Chile and the chloroplast and animal mitochondrial DNA (mtDNA) gene sequences were analysed to investigate the floral environment surrounding the midden, and the identity of the midden agent. The plant sequences, together with the macroscopic identifications, suggest the presence of 13 plant families and three orde...
Malaysia remains as a crossroad of different cultures and peoples, and it has long been recognized that studying its population history can provide crucial insight into the prehistory of Southeast Asia as a whole. The earliest inhabitants were the Orang Asli in Peninsular Malaysia and the indigenous groups in Sabah and Sarawak. Although they were the earliest migrants in this region, these trib...
Adequate species’ identification is critical for the detection and monitoring of biological invasions. In this study, we proposed assessed efficiency newly created primer sets genetic non-indigenous species (NIS) fishes in Volga basin based on: (a) a “long” fragment cytochrome c oxidase subunit one mitochondrial gene (COI) (0.7 kb), used “classical” DNA barcoding; (b) short 3’-fragment (0.3 kb)...
