Identification of Signal Pathways and Hub Genes of Pulmonary Arterial Hypertension by Bioinformatic Analysis by Rui-Qi Wei, Wen-Mei Zhang, Zhe Liang, Chunmei Piao, Guangfa Zhu

“…GO enrichment analysis showed that these DEGs were mainly enriched in mitotic nuclear division, organelle fission, chromosome segregation, nuclear division, and sister chromatid segregation. Significant KEGG pathway enrichment included ribosome biogenesis in eukaryotes, RNA transport, proteoglycans in cancer, dilated cardiomyopathy, rheumatoid arthritis, vascular smooth muscle contraction, focal adhesion, regulation of the actin cytoskeleton, and hypertrophic cardiomyopathy. …”

<i>Allosaurus europaeus</i> (Theropoda: Allosauroidea) Revisited and Taxonomy of the Genus by André Burigo, Octávio Mateus

“…A detailed cranial description and specimen-based phylogeny were performed and resolved many of the open questions: (1) The diversity of <i>Allosaurus</i> is limited to three named species: <i>A. fragilis</i>, <i>A. europaeus</i>, and <i>A. jimmadseni</i>. (2) Nine autapomorphies were found in <i>A. europaeus</i>, confirming the validity of the species. (3) Phylogenetic analyses place both Portuguese specimens in the genus <i>Allosaurus</i>, based on the following synapomorphies: jugal bone lateral view, relative heights of quadratojugal prongs, the dorsal prong is equal in height, the jugal bone in lateral view shows shallow accessory pneumatization of the antorbital fossa, the palatine pneumatic recess shape is small, and lacrimal horn morphology has a triangular horn. (4) The Andrés specimen is placed with the <i>A. europaeus</i> and they are considered here to be the same species, which is paleo-geographically and biochronologically congruent. (5) <i>A. europaeus</i> and <i>A. jimmadseni</i> are sister taxa and closer to each other than to <i>A. fragilis</i>. …”
