Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

Comparative diagnostic accuracy study of point of care ultrasound techniques for detection of left atrial enlargement by hospital medicine physicians from archived echocardiogram images

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background Left atrial enlargement (LAE) is predictive of cardiovascular morbidity and mortality. Prior studies of point‐of‐care ultrasound (POCUS) interpretation methods for identifying LAE utilized older echocardiographic reference ranges. Objectives Compare the test characteristics of hospitalist‐performed POCUS techniques for identifying ...

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

open access: yesJournal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...
