An open-source framework for synthetic post-dive Doppler ultrasound audio generation

PLOS ONE, 18(4).

By: D. Le n, A. Hoang n, A. Azarang n, R. Lance*, M. Natoli*, A. Gatrell*, S. Blogg*, P. Dayton n ...

TL;DR: A method to generate synthetic post-dive data using DU signals collected in both precordium and subclavian vein with varying degrees of bubbling matching field-standard grading metrics is developed, allowing for researchers to tune the produced dataset for their desired purpose.

2023 journal article

Development of a graphical user interface for automatic separation of human voice from Doppler ultrasound audio in diving experiments

PLOS ONE, 18(8).

TL;DR: A graphical user interface (GUI) to perform automatic speech recognition and aid in Non-speech and Speech separation and has the potential to significantly accelerate the reuse of previously-acquired datasets is developed. (via Semantic Scholar)

Effect of Anesthetic Carrier Gas on In Vivo Circulation Times of Intravenously Administered Phospholipid Oxygen Microbubbles in Rats


By: P. Durham n, A. Upadhyay*, J. Navarro-Becerra*, R. Moon*, M. Borden*, P. Dayton n, V. Papadopoulou n

author keywords: Bubble; Contrast-enhanced ultrasound; Ultrasound contrast agent; Tumor hypoxia; Radiation therapy
MeSH headings : Rats; Animals; Oxygen; Phospholipids; Microbubbles; Ultrasonography; Fluorocarbons; Anesthetics; Contrast Media
TL;DR: The findings suggest that the apparent longevity and persistence of oxygen microbubbles in circulation may not be reflective of oxygen delivery when the animal is anesthetized breathing air. (via Semantic Scholar)

2023 journal article

Overcoming biological barriers to improve treatment of a Staphylococcus aureus wound infection


By: V. Papadopoulou n, A. Sidders*, K. Lu*, A. Velez*, P. Durham n, D. Bui*, M. Angeles-Solano*, P. Dayton n, S. Rowe*

TL;DR: This study combat the two major barriers to successful aminoglycoside treatment against a biofilm-infected wound: limited antibiotic uptake and limited biofilm penetration by employing palmitoleic acid, a host-produced monounsaturated fatty acid that perturbs the membrane of gram-positive pathogens and induces gentamicin uptake.
