Description: Using biomimetics and 3-material 3D printing, we set out to create the first tessellated intervertebral disc implant prototype based on a self-stiffening structure found in shark cartilage. Our prototypes increased in stiffness with increasing load, similarly to shark cartilage, proving that artificial tessellated material may be a viable option for nonmetallic implants.
Thesis defense: "Gene expression of hypoxia-inducible factor (HIF-1a), its regulators, and its putative downstream targets in ventricle and telencephalon of the anoxia-tolerant turtle (Trachemys scripta)"

Description: This thesis assessed the role of HIF-1α in ventricle and telencephalon of one of the vertebrate champions of anoxia survival, the red-eared slider turtle (Trachemys scripta). Turtles acclimated to 21°C or 5°C were exposed to either normoxia, anoxia (24 h at 21°C; 24 h or 14 d at 5°C) or anoxia + reoxygenation and the effects of oxygenation state, as well as cold acclimation in normoxia, on HIF-1α and HIF-2α gene expression, some HIF regulators and eleven putative downstream targets of HIF were quantified by qPCR.
