Embolization for pediatric trauma.

Background: The management of pediatric trauma with trans-arterial embolization is uncommon, even in level 1 trauma centers; hence, there is a dearth of literature on this subject compared to the adult experience.

Objective: To describe a single-center, level 1 trauma center experience with arterial embolization for pediatric trauma.

Materials And Methods: A retrospective review was performed to identify demographics, transfusion requirements, pre-procedure imaging, procedural details, adverse events, and arterial embolization outcomes over a 19-year period.

Exposure to IR Rotations in Osteopathic Medical Schools: Trends in Residency Applications and Matching.

Medical student exposure to interventional radiology (IR) through dedicated rotations represents a vital component for students to consider IR as a career and to ensure a successful match into the integrated residency pathway. Students from osteopathic medical schools have historically been underrepresented in integrated IR positions. During the 2022 match, 84.

Generation Z and the Radiology Workforce: Ready or Not, Here I Come.

In 2023, the radiology community will experience the beginning of a generational change by matching its first class of Generation Z residents. To best welcome and embrace the changing face of the radiology workforce, this Viewpoint highlights the values that this next generation will bring, how radiologists can improve the way they teach the next generation, and the positive impact that Generation Z will have on the specialty and the way radiologists care for patients.

The Frog Motor Nerve Terminal Has Very Brief Action Potentials and Three Electrical Regions Predicted to Differentially Control Transmitter Release.

The action potential (AP) waveform controls the opening of voltage-gated calcium channels and contributes to the driving force for calcium ion flux that triggers neurotransmission at presynaptic nerve terminals. Although the frog neuromuscular junction (NMJ) has long been a model synapse for the study of neurotransmission, its presynaptic AP waveform has never been directly studied, and thus the AP waveform shape and propagation through this long presynaptic nerve terminal are unknown. Using a fast voltage-sensitive dye, we have imaged the AP waveform from the presynaptic terminal of male and female frog NMJs and shown that the AP is very brief in duration and actively propagated along the entire length of the terminal.
