Biogeography; Cytochrome b; Endemism

The genetic relationships among 17 species of Astyanax from the Iguaçu River and adjacent river basins in Brazil were examined using nucleotide sequences of the mitochondrial cytochrome b gene (cytb). Congruent trees were constructed using neighbor-joining, maximum-likelihood, and Bayesian methods. The resulting clades suggest that at least three major groups share ... more

Behavior; Dopamine; Genetic polymorphism; Temperament

The aim of this study was to analyze the allelic frequency distribution and segregation among breeds and/or between different cattle genetic groups of four novel single nucleotide polymorphisms of the bovine DRD1 and DRD5 genes and one reported SNP from the DRD4 gene. One hundred and nine-animals from ten different cattle breeds were genotyped and allelic frequencies for each locus were ... more

morphology; Phylogeny; Salix matsudana; Species concept

The morphological species concept is based on morpho­logical traits, which are often subject to subjectivity or artifact. Molecular evidence is needed to test the reliability of morphological classification of taxa that are controversial and to provide appropriate taxonomic de­limitation. In this study, we used 15 single-copy nuclear loci and 2 chlo­roplast fragments to verify the ... more

Adhesion ability; Enterococcus faecalis; morphology; Viable but nonculturable

Enterococcus faecalis may enter a viable but nonculturable (VBNC) state under adverse conditions. E. faecalis, the major bacterial species present in failed root canal treatments, is thought to survive after endodontic treatment by entering a VBNC state. In this study, we characterized the VBNC state of E. faecalis. We designed 3 different protocols to successfully ... more

Bassia indica is a natural herb of medical and economic importance with a worldwide distribution, including in various regions of Egypt. It is primarily used for healing and is also considered a green fodder and can be used to remediate salty soils. We investigated morphological and germination parameters as well as the karyotype and genetic variation of ... more

Alcoholism; Apoptosis; blood; Cerebral ischemia; miRNA; morphology

One of the main global causes of mortality is cerebral ischemia. Studies report that alcohol abuse causes health problems, aggravating the conditions of neurological diseases. The role of microRNAs has been highlighted in the literature as biomarkers in various types of diseases, including neurological disorders. Evidence of dysregulation of serum miRNAs related to ... more

Alcoholism; Apoptosis; Cerebral ischemia; miRNA-21; morphology

Cerebral ischemia is one of the main causes of morbidity and mortality as Abusive use of alcohol also causes health problems, along with considerable social and economic repercussions. We examined how these two conditions affect histopathological signs, morphometrics, expression of apoptosis-related proteins CASPASE 3 and BCL2, and serum gene expression of miRNA-21 ... more

Maternal post-traumatic stress disorder (PTSD) increases the risk of adverse neurodevelopmental outcomes in the child. Epigenetic alternations may play an essential role in the negative effects of PTSD. This study was aimed to investigate the possible epigenetic alterations of maternal PTSD, which underpins the developmental and behavioral impact. 24 pregnant Sprague-Dawley (SD) rats ... more

The evolutionary significant units (ESUs) of the salamander Pachyhynobius shangchengensis (Hynobiidae) in the Dabieshan mountains, southeastern China, were identified based on mitochondrial DNA data. We used methods for detecting cryptic species, such as the minimum spanning tree, the automatic barcode gap discovery, and the generalized mixed Yule-coalescent model; geographical ... more
