Mechanical Loading As Potential Treatment For Wnt Inhibitor Induced Bone Loss, Juraj Zahatnansky Md, Daniel Dick, Gabrielle Foxa, Robert Baker, Bart Williams Phd

Research Day

The Wnt signaling pathway has been shown to play a role in bone homeostasis and carcinogenesis. On the one hand, a decrease in signaling has been associated with a decrease in bone mass, on the other, an increase in signaling with cancer development. LGK974 is a Wnt signaling inhibitor currently being investigated as a potential cancer therapeutic agent. This molecule inhibits Porcupine, a transmembrane protein necessary for Wnt ligand secretion. In light of the above and based on our preliminary data, treatment with LGK974 leads to bone mass loss. Our investigation aims to address whether such bone loss can be …

Retrospective Analysis Of Contact Sport Participation On Cognitive Function In Healthy Athletes, Lisa C. Martinez

Cal Poly Humboldt theses and projects

This study explored the effects of contact and limited contact sport participation on neurocognitive function in non-concussed collegiate and adolescent athletes over time. Athletes participating in contact and limited contact sports have an increased risk of sustaining neurocognitive injuries, known as subconcussive blows, compared to non-contact sport athletes. We hypothesized that athletes participating in contact and limited contact sports, would exhibit a deficit in neurocognitive function following multiple seasons of play when compared to athletes participating in non-contact sports. Using a mixed repeated measures MANOVA statistical design, we analyzed computerized neurocognitive baseline ImPACT composite scores (verbal memory, visual memory, visual …
