The academic experience in distance (virtual) rounding and education of emergency surgery during COVID-19 pandemic.

Background: To cope with COVID-19 pandemic control precautions, many surgical residency programs have adopted a Declared Health Emergency rotation to minimize exposure to the COVID-19. We evaluated the experience and educational value of virtual education activities by reviewing the perceptions of the Declared Health Emergency rotation participants through survey questionnaire analysis.

Methods: Participants of the Declared Health Emergency rotation virtual educational activities were asked to complete a survey questionnaire describing their perception and experience.

Radiofrequency-Triggered Drug Release from Nanoliposomes with Millimeter-Scale Resolution Using a Superimposed Static Gating Field.

Drug delivery to a specific site in the body typically relies on the use of targeting agents that recognize a unique biomarker. Unfortunately, it is often difficult to identify unique molecular signatures that exist only at the site of interest. An alternative strategy is to deliver energy (e.

MicroRNAs control intestinal epithelial differentiation, architecture, and barrier function.

Background & Aims: Whereas the importance of microRNA (miRNA) for the development of several tissues is well established, its role in the intestine is unknown. We aimed to quantify the complete miRNA expression profile of the mammalian intestinal mucosa and to determine the contribution of miRNAs to intestinal homeostasis using genetic means.

Methods: We determined the miRNA transcriptome of the mouse intestinal mucosa using ultrahigh throughput sequencing.
