Phage‐mediated horizontal transfer of Salmonella enterica virulence genes with regulatory feedback from the host

iMeta, EarlyView.
In this study, we found evidence of phage‐mediated horizontal transfer of virulence genes in Salmonella enterica in global habitats from a molecular evolutionary perspective. Notably, csrA, a global regulator in Salmonella enterica, curbed horizontal gene transfer by inhibiting the cyclization and release of prophage.

Is It an Intrapericardial Mass or a Localized Pericardial Effusion? A Case Report of Tuberculous Pericarditis Evaluated by Multimodal Imaging

Journal of Clinical Ultrasound, EarlyView.
Tuberculous pericarditis is a common type of pericarditis, but it is difficult to be diagnosed. The application of combined transesophageal echocardiography, contrast echocardiography, and CT multimodal imaging provides sufficient clinical diagnosis basis and guidance for distinguishing encapsulated pericardial effusion or mass.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...
