Sporadic gliomas in companion dogs provide a window on the interaction between tumorigenic mechanisms and host environment. We compared molecular profiles of canine with those human pediatric adult to characterize evolutionarily conserved mammalian mutational processes gliomagenesis. Employing whole-genome, exome, transcriptome, methylation sequencing 83 gliomas, we found alterations shared such as receptor tyrosine kinases, TP53 cell-cycle pathways, IDH1 R132. Canine showed high similarity...

Astrocytomas and oligodendrogliomas represent one third of histologically confirmed canine brain tumors. Our purpose was to describe the magnetic resonance (MR) imaging features intracranial astrocytomas examine for MR that differentiate these tumor types. Thirty animals with astrocytoma (14) or oligodendroglioma (16) were studied. All 12 located in cerebrum thalamus, remainder cerebellum caudal brainstem. Most (27/30) tumors associated both gray white matter. The signal characteristics...

ABSTRACT A severe, sometimes fatal respiratory disease has been observed in captive ball pythons ( Python regius ) since the late 1990s. In order to better understand this and its etiology, we collected case control samples performed pathological diagnostic analyses. Electron micrographs revealed filamentous virus-like particles lung epithelial cells of sick animals. Diagnostic testing for known pathogens did not identify an etiologic agent, so unbiased metagenomic sequencing was performed....

Previously we showed therapeutic efficacy of unprotected miR-124 in preclinical murine models glioblastoma, including heterogeneous genetically engineered by exploiting the immune system and thereby negating need for direct tumor delivery. Although these data were promising, to implement clinical trials, required a scalable formulation that afforded protection against circulatory RNases.We devised lipid nanoparticles encapsulate protect miRs from degradation provide enhanced delivery into...
