Individuals of mussels were collected in ponds from a commercial shrimp farm the Unare region, Anzoátegui State, Venezuela. Identification was carried out using dichotomous keys and corroborated via analysis similarities between sequences partial mitochondrial DNA cytochrome oxidase gene Mytella strigata (Hanley, 1843) reported GenBank with 99-100% similarity. Morphological analyses further sup...

The Lanyu pig is an indigenous breed from the Lanyu Islet, which is southeast of Taiwan. Two herds of Lanyu pigs were introduced from the Lanyu Islet into Taiwan in 1975 and 1980. The current population of conserved Lanyu pigs consists of only 44 animals with unknown genetic lineage. The Lanyu pig possesses a distinct maternal genetic lineage remote from Asian and European pigs. The present stu...

Orosanga japonica (Melichar, 1898) (Hemiptera: Ricaniidae) is an invasive species in Turkey and Caucasian area of the Palearctic. Seventeen localities were selected for molecular studies 163 samples from Black Sea Marmara coasts collected between 2019-2020 evaluated potential distribution habitat suitability with maximum entropy method CORINE Land Cover (CLC) index. Molecular analysis revealed ...

The poorly known Clymene dolphin ( Stenella clymene ) is a small oceanic cetacean distributed in tropical and subtropical waters of the Atlantic Ocean. In this study, we report, for first time, vagrant individual Argentina (Rada Tilly) that represents current southern-most record species. We provide molecular identification dolphin, based on partial sequences mitochondrial cytochrome b gene, ge...

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...

considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (ua), a soluble salt of depleted uranium (du). we examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (bht), to prevent ua-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. beta-glucan (150 nm) and bht (20 nm) attenuated ua-indu...

Mitochondria contain their own genetic system to express a small number of hydrophobic polypeptides, including cytochrome b, an essential subunit of the bc(1) complex of the respiratory chain. In this paper, we show in yeast that Cbp3, a bc(1) complex assembly factor, and Cbp6, a regulator of cytochrome b translation, form a complex that associates with the polypeptide tunnel exit of mitochondr...

Acquisition of detailed knowledge of the structure and evolution of Trypanosoma cruzi populations is essential for control of Chagas disease. We profiled 75 strains of the parasite with five nuclear microsatellite loci, 24Salpha RNA genes, and sequence polymorphisms in the mitochondrial cytochrome oxidase subunit II gene. We also used sequences available in GenBank for the mitochondrial genes c...
