Monitoring Changes in Sperm Concentration and Quality Help Improve Captive Breeding Outcomes of the Endangered Amphibian Rawlinsonia littlejohni

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are among the most threatened taxonomic groups, with many species experiencing rapid declines that have resulted in small, isolated populations vulnerable to inbreeding depression and reduced fertility. One major outcome of inbreeding is lowered fecundity, often linked to morphological changes in gametes.

Predicting cochlear structural alterations from auditory function in age‐related hearing loss mice based on optical coherence tomography

open access: yesJournal of Intelligent Medicine, EarlyView.
Abstract With global population aging, age‐related hearing loss has become a major public health concern. Understanding the relationship between auditory functional decline and cochlear structural degeneration is essential for early detection and precise intervention.

Comparison of 3‐Dimensional Ultrasound and Computed Tomography for Imaging of Abdominal Aortic Aneurysms

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives Three‐dimensional ultrasound (3D US) is emerging as a novel imaging method for abdominal aortic aneurysms (AAAs) as it creates a low‐cost 3D AAA overview without harmful radiation and nephrotoxic contrast agents, as opposed to conventional imaging. 3D US can be used with a non‐nephrotoxic contrast agent (3D‐CEUS) for lumen delineation.

Quantifying harvest of barren‐ground caribou off a winter road in the Northwest Territories – An Indigenous Guardian‐led initiative

open access: yesThe Journal of Wildlife Management, EarlyView.
The North Slave Métis Alliance's Indigenous Guardianship Program conducted on‐the‐ground patrols monitoring caribou interactions with the Tibbitt to Contwoyto Winter road and quantify caribou harvest. Quantifying the impacts of winter roads on barren‐ground caribou herds supports community members’ commitment to safeguarding their traditional territory

The Early Regenerative Events in the Human Tympanic Membrane After In Vivo Traumatization

open access: yesThe Laryngoscope, EarlyView.
At 20 h after in vivo traumatization a regenerative response in the human tympanic membrane is activated. The results show an upregulated proliferation activity in the UPT in early healing and confirm the previously described regenerative regions of the annulus and malleus.
