Congratulations to Gustavo for his first manuscript published in Acta Biomaterialia (Impact Factor 9.7)! Pulmonary air leaks are amongst the most common complications in lung surgery and adhesives are commonly tested on pig and rat lungs, but applied to human lungs. We characterize the mechanical properties of the visceral pleura, the surface layer of the lung, of human lungs for the first time, and compare its performance to animal surrogates. 

Dr. Badrou presented advances in structural breathing computational simulations of the human lungs at the World Congress on Computational Mechanics 2024 in Vancouver Canada.  Congratulations!

Prof. Eskandari was invited to chair the Respiratory Biomechanics Session at the 29th Congress of the European Society for Biomechanics.

Congratulations to Katie and Samaneh for receiving the Graduate Research Mentorship Program and Dissertation Year Program Fellowships ! 

Congratulations to joint first co-authors Samaneh and Crystal on publishing recent groundbreaking scientific findings in the prestigious American Journal of Respiratory and Critical Care Medicine (Impact Factor 30.5). In order to mitigate ventilator injury, we address a long-standing debate in the pulmonary medical community: do ventilator breathing mechanics mimic that of natural breathing? Using an innovative multi-apparatus interface developed in our lab, we minimized confounding factors by subjecting the same lung specimen to both loading modes. We found exclusive evidence that both global and local energetics, stretches, and distortions are reduced in physiological breathing compared to artificial ventilation. This also holds implications for the COVID-19 Pandemic. News Feature

Congratulations to Samaneh on her publication in Acta Biomaterialia (Impact Factor 10.6), titled "Biaxial mechanical properties of the bronchial tree: Characterization of elasticity, extensibility, and energetics, including the effect of strain rate and preconditioning." 

Congratulations to Talyah on her first manuscript, coauthored by Katie, Samaneh, and Crystal in Physiological Reports titled "Associating local strains to global pressure–volume mouse lung mechanics using digital image correlation ." By quantifying strain evolutionary behavior in relation to pressure–volume measures, we associate time-continuous local to global mouse lung mechanics for the first time and further examine the role of volume and rate dependency. Research was conducted in collaboration with the Nordgren Lab (Colorado State University)

The non-confidential disclosure of our new device for pulmonary function testing in the 21st century (also published as a PCT patent application) is now available through the Office of Technologies Partnerships at UCR.
