1. Quantification of cell-free circulating mitochondrial DNA copy number variation in hepatocellular carcinoma
SUMMARY OBJECTIVE: Hepatocellular carcinoma is the most common primary malignant liver tumor. Mitochondrial DNA copy number has been shown to be associated with various malignancies. However, there has not been any study on the absolute quantification of mtDNA copy number in hepatocellular carcinoma. The aim of this study was to develop a new method for abs

2. O código de barras de DNA revela os primeiros registros de três gêneros raros de coleópteros nos lagos do norte do Egito
Resumo Uma espécie de coleópteros aquático da família Dytiscidae e dois gêneros de coleópteros aquáticos da família Hydrophilidae foram registrados no período de verão e representam os primeiros registros nos lagos egípcios. Os besouros foram coletados em dois lagos do norte, o lago Idku e o lago Burullus, e identificados por características morf

3. Código de barras de DNA à base de CO1 para avaliar a diversidade de Pteropus giganteus do estado de Azad Jammu e Caxemira, Paquistão
Resumo A raposa-voadora (Pteropus giganteus), também conhecida como morcego indiano, pertence à ordem dos Chiroptera e à família Pteropodidae. A presente pesquisa dá ênfase ao código de barras de DNA de P. giganteus em Azad Jammu e Caxemira. Sequências genéticas dos morcegos foram amplificadas, e os produtos de PCR foram sequenciados e examinados po

4. Bacteriological assessment and multiplex-PCR test for the detection of meat adulteration of different animal species
Abstract Meat samples of various animal species have been obtained from Giza Governorate's butcher shops, common retail markets, veterinary faculties, Zoo and hospitals. Physical, bacteriological, and molecular analysis was carried out on the meat samples. Physical examination showed that typical and untypical meat differed. Bacteriological examination showe

5. Quantification of mitochondrial DNA damage and copy number in circulating blood of patients with systemic sclerosis by a qPCR-based assay,
Abstract Background: Although not fully understood, oxidative stress has been implicated in the pathogenesis of different autoimmune diseases such as systemic sclerosis. Accumulating evidence indicates that oxidative stress can induce mitochondrial DNA (mtDNA) damage and variations in mtDNA copy number (mtDNAcn). Objective: The aim of this study was to exp

6. Genetic Diversity and Phyletic Evolution of Eleven Chinese Indigenous and Three Commercial Chicken Breeds by mtDNA Sequences
ABSTRACT Chinese indigenous chicken breeds are geographically widespread, and a total of 116 indigenous chicken breeds are listed as Chinese national genetic resources. However, these indigenous chicken breeds are facing serious challenges as declining population and germplasm degeneration because lots of commercial chicken breeds had been introduced. In thi

7. How history and geography may explain the distribution in the Comorian archipelago of a novel mutation in DNA repair-deficient xeroderma pigmentosum patients
Abstract Xeroderma pigmentosum (XP) is a rare, genetic, autosomal nucleotide excision repair-deficient disease characterized by sun-sensitivity and early appearance of skin and ocular tumors. Thirty-two black-skinned XP from Comoros, located in the Indian Ocean, were counted, rendering this area the highest world prevalence of XP. These patients exhibited a

8. Isoenzyme and molecular approach for authenticating and monitoring of animal cell lines
Abstract: Authentication of cell lines is of paramount importance to validate the results from their use in biomedical research. Although isoenzyme polymorphism is the standard method, molecular methods based on mitochondrial DNA (mtDNA) have been developed to replace it. The aim of this study was the improvement of our isoenzyme electrophoretic analysis and

9. Leigh Syndrome Due to mtDNA Pathogenic Variants
Abstract Leigh syndrome is a devastating neurodegenerative disease, typically manifesting in infancy or early childhood. Hallmarks of the disease are symmetrical lesions in the basal ganglia or brain stem on MRI, and a clinical course with rapid deterioration of cognitive and motor functions. It is genetically heterogeneous, causative mutations have been dis

10. The Complete Mitochondrial Genome of the Donganyellow Chicken and Its Phylogenetic Analyses
ABSTRACT Donganyellow chicken (Gallus gallusdomesticus, DYC) is one of the famous native breeds of Hunan province in China. It is the first time that the complete mitochondrialgenome sequence of DYC was reported. The total length of the mtDNA is16, 786bp. It contains 22transfer RNA genes, 2 ribosomal RNA genes,13 protein-coding genes and 1 D-loop region. The

11. Crane flies (Diptera, Tipuloidea) from southern Neotropical salt marshes: survey with DNA barcoding
ABSTRACT Crane flies are the most diverse group within Diptera, but they are rarely studied in coastal ecosystems. Considering the scarcity of information on the biology and ecology of this group in the Neotropics, and the sparse literature available for taxonomic identification, we developed a descriptive checklist that incorporates morphology and DNA barco

12. Phylogeographic analyses of the pampas cat (Leopardus colocola; Carnivora, Felidae) reveal a complex demographic history
Abstract The pampas cat is a small felid that occurs in open habitats throughout much of South America. Previous studies have revealed intriguing patterns of morphological differentiation and genetic structure among its populations, as well as molecular evidence for hybridization with the closely related L. tigrinus. Here we report phylogeographic analyses e
