Abstract:

This study focuses on the components and levels of polycyclic aromatic hydrocarbons (PAHs) and their derivatives (MPAHs and OPAHs) in plasma samples from 19 oil workers, pre- and post-workshift, and their exposure–response relationship with mitochondrial DNA (mtDNA) methylation. PAH, MPAH, OPAH, and platelet mtDNA methylation levels were determined using a gas chromatograph mass spectrometer (GC-MS) and a pyrosequencing protocol, respectively. The total plasma concentrations of PAHs in mean value were, respectively, 31.4 ng/mL and 48.6 ng/mL in pre- and post-workshift, and Phe was the most abu

Abstract:

AbstractThe aim of the study was to describe the mechanism of mitochondrial DNA inheritance in a group of farmed raccoon dogs. The study involved 354 individuals. Whole peripheral blood was the research material. DNA was isolated and PCR was performed for two fragments of mitochondrial genes: COX1 (cytochrome oxidase subunit 1 gene) and COX2 (cytochrome oxidase subunit 2 gene). The PCR products were sequenced and subjected to bioinformatics analyses. Three mitochondrial haplotypes were identified in the COX1 gene fragment and two in the COX2 gene fragment.

Abstract:

The study aimed to analyze the genetic diversity in the Czech population of Apis mellifera using mitochondrial DNA markers, tRNAleu-cox2 intergenic region and cox1 gene. A total of 308 samples of bees were collected from the entire Czech Republic (from colonies and flowers in 13 different regions). Following sequencing, several polymorphisms and haplotypes were identified. Analysis of tRNAleu-cox2 sequences revealed three DraI haplotypes (C, A1, and A4). The tRNAleu-cox2 region yielded 10 C lineage haplotypes, one of which is a newly described variant. Three A lineage haplotypes were identifie

Abstract:

AbstractSparganosis is a serious food-borne parasitic zoonosis caused by infection with Spirometra spargana. The prevalence of sparganum infection in wild frogs (Rana nigromaculata, R. limmochari, R. temporaria and Bufo gargarizans) was investigated in Henan Province of central China during 2008–2012. Of 3482 caught wild frogs, 565 (16.23%) were found to be infected with plerocercoids (spargana) of the genus Spirometra. Spargana were found in 14.85% (320/2155) of R. nigromaculata, 20.82% (233/1119) of R. limmochari and 10.91% (12/110) of R. temporaria frogs. However, no sparganum was found in

Abstract Formalin-fixed paraffin embedded (FFPE) tissue is the most common histopathological technique for tumour assessment in the veterinary pathology. Due to easy availability of FFPE blocks, the aim of this retrospective study was to identify molecular defects caused by mutations in mitochondrial DNA (mtDNA) in cases of canine malignant mammary gland tumours (MGTs). DNA was isolated from 88 FFPE samples, then quantity and quality analyses were performed. Amplification was conducted on 10 selected fragments of 8 mitochondrial genes (COX1, COX3, ND1, ND2, ND4, ND4L, ND5 and ATP6), and finall

Abstract:

The information about mtDNA methylation is still limited, thus epigenetic modification remains unclear. The lack of comprehensive information on the comparative epigenomics of mtDNA prompts comprehensive investigations of the epigenomic modification of mtDNA in different species. This is the first study in which the theoretical CpG localization in the mtDNA reference sequences from various species (12) was compared. The aim of the study was to determine the localization of CpG sites and islands in mtDNA of model organisms and to compare their distribution. The results are suitable for further

Abstract:

Abstract Honey bees are used in intensive way in agriculture due to their vital role in pollination of crops. Moreover, there are many valuable products from the bee colonies. Unfortunately, there are many enemies to honey bees. These enemies belong to various taxonomic ranks, including birds, insects and mites. Serious damages can be caused to honey bee colonies by these enemies. The sophisticated evolutionary relationships between honey bees and their enemies are not well investigated. In this study, phylogenetic trees between honey bees and their enemies were constructed based on the mtDNA

Honey bee Apis cerana is widely distributed in Asia and the Indonesian archipelago, including Sumatra. We studied the molecular variations of A. cerana using cytochrome c oxidase subunits 1 and 2 genes (cox1 and cox2) and the cox1/cox2 intergenic spacers (igs) in several altitudes in the six provinces of Sumatra. We explored the haplotype distributions of those three mtDNA markers for A. cerana in the low-, mid-, and highlands of Sumatra. We also analyzed their relationship with A. cerana in Sundaland and Asia using those markers. Our study revealed 12 new haplotypes of A. cerana cox1 in Sumat

Abstract:

Despite the epidemiological significance of the trematodes Clonorchis sinensis and Metagonimus suifunensis, these species are insufficiently studied in the Russian Far East. In this work, we compare various nuclear and mitochondrial markers used for population genetic studies, based on previously published articles, as well as new data on the nad1 mtDNA gene obtained for M. suifunensis. Even such conservative markers as the ITS1–5.8S-ITS2 rDNA region and the cox1 mtDNA gene are suitable for the analysis of genetic variability in the C. sinensis population, while more variable mtDNA genes must

Abstract:

Spinocerebellar ataxias (SCAs) are a genetically heterogeneous group of cerebellar degenerative disorders, characterized by progressive gait unsteadiness, hand incoordination and dysarthria. The mutational mechanism in spinocerebellar ataxia type1 (SCA1), a dominantly inherited form of SCA, consists of an expanded trinucleotide CAG repeat that encodes a polyglutamine tract in ataxin1. Mutant SCA1 transgenic mice present pathological cerebellar signs with concomitant progressive Purkinje neuron atrophy and relatively little cell loss, at least in the early stage of life; this evidence suggests

High fishing pressures, coupled with declining fish stocks has led to changes in mean size and reproductive age of many exploited species.
