How should characters and taxa be sampled to resolve efficiently the phylogeny of ancient and highly speciose groups? We addressed this question empirically in the treefrog family Hylidae, which contains > 800 species and may be nonmonophyletic with respect to other anuran families. We sampled 81 species (54 hylids and 27 outgroups) for two mitochondrial genes (12S, ND1), two nuclear genes (POM...

Mitochondrial enzyme activities and ultrastructure of mitochondria prepared from klotho mutant mice were compared with those in wild-type mice. We also measured the levels of expression of ND1, 51kDa, and 75kDa mRNA associated with the genes encoding NADH dehydrogenase and complex I and that of alpha cardiac myosin heavy chain mRNA in both groups. Mitochondrial NADH oxidoreductase activity was ...

We aimed to investigate the influence of inverse moxibustion on the translocation of telomerase from cardiomyocyte mitochondria of growing mice following exercise. Sixty mice were divided into six groups (n = 10 each). For the control groups, mice were handled each day, but not subjected to moxibustion. For the inverse moxibustion groups, Guan yuan and Zusanli acupuncture points were moxibusted...

In the present study, we determined the complete mitochondrial DNA (mtDNA) sequences of two species of Cistopus, namely C. chinensis and C. taiwanicus, and conducted a comparative mt genome analysis across the class Cephalopoda. The mtDNA length of C. chinensis and C. taiwanicus are 15706 and 15793 nucleotides with an AT content of 76.21% and 76.5%, respectively. The sequence identity of mtDNA ...

BACKGROUND Colorectal cancer as a mortal disease affected both sexes of all ethnic and racial human groups. Former studies have indicated some mutations in the mitochondrial DNA (mtDNA) in different human cancers. Complex I NADH has the most subunits encoded by mtDNA. For a better understanding of the mtDNA abnormality in colorectal cancer some genes of this complex is screened for existence of...

Economical breeding is important to obtain maximum gain from the breeding in the animal sector. The economic loss has to be eliminated or should be minimized. The liver fluke, Fasciola hepatica, present mostly in sheep and dairy cattle affect the yield of animals and even cause their death. To eliminate or minimize the impact of these parasites on the animals, it is important to understand the ...
