Elucidating Human Mitosis Using an Anaphase-Like Cell-Free System.

A balanced progression through mitosis and cell division is largely dependent on orderly phosphorylation and ubiquitin-mediated proteolysis of regulatory and structural proteins. These series of events ultimately secure genome stability and time-invariant cellular properties during cell proliferation. Two of the core enzymes regulating mitotic milestones in all eukaryotes are cyclin dependent kinase 1 (CDK1) with its coactivator cyclin B, and the E3 ubiquitin ligase anaphase promoting complex/cyclosome (APC/C).

An Evaluation of Kiosks for Direct-to-Consumer Telemedicine Using the National Quality Forum Assessment Framework.

Evaluation of direct-to-consumer (DTC) telemedicine programs has focused on care delivery via personal electronic devices. Telemedicine kiosks for the delivery of virtual urgent care services have not been systematically described. Our institution has placed kiosks for DTC urgent care in pharmacies.

Complex Cartography: Regulation of E2F Transcription Factors by Cyclin F and Ubiquitin.

The E2F family of transcriptional regulators sits at the center of cell cycle gene expression and plays vital roles in normal and cancer cell cycles. Whereas control of E2Fs by the retinoblastoma family of proteins is well established, much less is known about their regulation by ubiquitin pathways. Recent studies placed the Skp1-Cul1-F-box-protein (SCF) family of E3 ubiquitin ligases with the F-box protein Cyclin F at the center of E2F regulation, demonstrating temporal proteolysis of both activator and atypical repressor E2Fs.

Cell cycle oscillators underlying orderly proteolysis of E2F8.

E2F8 is a transcriptional repressor that antagonizes E2F1 at the crossroads of the cell cycle, apoptosis, and cancer. Previously, we discovered that E2F8 is a direct target of the APC/C ubiquitin ligase. Nevertheless, it remains unknown how E2F8 is dynamically controlled throughout the entirety of the cell cycle.

It's not just FaceTime: core competencies for the Medical Virtualist.

New applications for virtual healthcare have resulted in an expansion of medical care beyond traditional healthcare settings. However, the rapid development of telemedicine as a field has resulted in poor standardization of the care provided through this new medium. The authors outline core competencies to be used in developing training programs for practicing physicians, medical students, and other clinicians using telemedicine as a medium for providing patient care.
