Congrats to Audrey Ford on her paper titled “A Modular Approach to Creating Large Engineered Cartilage Surfaces” being accepted for publication in the Journal of Biomechanics. Current tissue engineering strategies are limited in developing large-scale tissues with clinically-relevant dimensions. In Audrey’s work, she explored using the inherent stickiness of new tissue growth to develop larger tissue surfaces with dimensions that are relevant for clinical applications.

Congrats to Semih Bezci on his paper titled “Effects of Axial Compression and Rotation Angle on Torsional Mechanical Properties of Bovine Caudal Discs” being accepted for publication in the Journal of the Mechanical Behavior of Biomedical Materials. In his work, Semih explores the relationship between rotation angle and axial compressive preload on torsional mechanics. The paper also provides statistical relationships between geometric parameters and mechanical properties, allowing researchers in spine biomechanics to easily account for differences in disc height or area and to compare results across various protocols presented in the literature.

Congrats to Ben Werbner and Minhao Zhou on their paper titled “A Novel Method for Repeatable Failure Testing of Annulus Fibrosus” being accepted to the Journal of Biomechanical Engineering. Testing failure properties of fiber reinforced soft materials, such as the annulus fibrosus and meniscus, has been a significant challenge due to tissue specimens often failing prematurely at the grips. Ben and Minhao’s collaborative effort combined computational (finite element modeling) and experimental approaches to determine an appropriate geometry to ensure that tissue failure would occur in the mid-substance. Experimental tests validated our models with approximately 90% agreement.

The O’Connell Lab has received a donation from a private donor and Berkeley alum for work with Professor Agogino on the Million Hands project. Part of this donation will also be used to expand ME178: Designing for the Human Body, which will focus on designing and prototyping prosthetics. A huge thank you from the entire lab!

Congratulations to Semih Bezci on having his paper accepted for publication in Spine. Passive diffusion is not sufficient for achieving full recovery from daily living; therefore, other mechanisms may play an important role in water absorption during an 8-hour bed-rest.
Semih’s recent research evaluated the role osmotic loading plays on time-dependent recovery behavior of the intervertebral disc following mechanical loading.

Recent work finite element modeling work by Bo Yang has been accepted for publication in Biomechanics and Modeling in Mechanobiology. In this study, Bo explores the importance of fiber angle orientation on disc mechanics in torsion, which will help researchers understand how some patients may be predisposed to more micro-damages in rotation or twisting.

Congratulations to Megan Pendleton for having her abstract accepted to the Annual ASBMR Meeting, which will be held in Denver, CO in September. Megan’s work focuses on understanding the effect of radiation on bone mechanical behavior. While her research is supported by NASA to understand what will happen to astronauts as they travel to Mars, her work can help cancer researchers understand what happens to noncancerous tissues following radiation treatment. You can find her abstract under Conference Proceedings.
