Z., Epigenetic mechanism of maternal post-traumatic stress disorder in delayed rat offspring development: dysregulation of methylation and gene expression, vol. 15, p. -, 2016.

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 were randomly grouped into PTSD and control groups.

Bovine dopamine receptors DRD1, DRD4, and DRD5: genetic polymorphisms and diversities among ten cattle breeds

A. M. Sifuentes-Rincón, Trejo-Tapia, A. G., Randel, R. D., Ambriz-Morales, P., Parra-Bracamonte, G. M., Sifuentes-Rincón, A. M., Trejo-Tapia, A. G., Randel, R. D., Ambriz-Morales, P., and Parra-Bracamonte, G. M., Bovine dopamine receptors DRD1, DRD4, and DRD5: genetic polymorphisms and diversities among ten cattle breeds, vol. 15, p. -, 2016.

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 estimated. There were significant differences in the allelic frequencies (P G and DRD5-378C>T were also significantly different between groups differing in genetic background.

Morphological and phylogeographic analysis of Brazilian tortoises (Testudinidae)

T. L. Silva, Venancio, L. P. R., and Bonini-Domingos, C. R., Morphological and phylogeographic analysis of Brazilian tortoises (Testudinidae), vol. 14. pp. 18604-18606, 2015.

The discriminative potentials of biogeography, vocalization, morphology, cytogenetics, hemoglobin, and molecular profiling of cytochrome b as taxonomic techniques for differentiating Brazilian tortoises were evaluated in this study. In Brazil, two species of tortoises are described, Chelonoidis carbonarius and Chelonoidis denticulatus. However, in the present study, some animals that were initially recognized based on morphological characters and coloring did not correspond to the typical pattern of C.
