• ATAD3A plays an oncogenic role in head and neck cancer

      Loveless, Jenni; Lang, Lewei; Jensen, Caleb; Teng, Yong; Dentistry (2020-02)
      With approximately 500,000 new cases diagnosed each year, head and neck squamous cell carcinomas (HNSCC) remain one of the leading causes of cancer related deaths. Thus, there is great interest to identify novel therapeutic targets against HNSCC. In this project, we aim to gain a deeper appreciation of ATAD3A, the ATPase family AAA-domain containing protein3A, and its oncogenic role in HNSCC, as well as its potential as a target in future patient therapies.

    • UV-VIS Spectral Profiles of Probable Photoinitiators in 3D Dental Resins

      Bowerman, Brielle; Brenes, Christian; Rueggeberg, Fred; Dentistry (2020-02)
      Dental 3D printing resins utilize a different range of wavelengths for photo-activation than those commonly found in visible light-cured, direct dental restorative materials, and thus contain different photoinitiators (PIs). This project sought to provide preliminary identification of PIs present in a wide variety of commercial, 3D photo-printing dental resins.
    • Invasion and Survival of Porphyromonas gingivalis in Human ARPE-19 Cells

      Yuan, Jessie; Swaminathan, Radhika; Cutler, Christopher; Arjunan, Pachiappan; Dentistry (2020-02)
      Age-related macular degeneration (AMD), a leading cause of irreversible vision loss in elderly is associated with several systemic conditions. Recent studies link Periodontal Disease (PD) to AMD. As we demonstrated previously, Porphyromonas gingivalis (Pg),a keystone oral-pathobiont that cause periodontitis, invades blood dendritic and gingival epithelial cells. However, there is no evidence that Pg invades retinal-pigment epithelial (RPE) cells. The primary objective of this study is to test whether Pg and its fimbrial-mutants invade human ARPE-19 cells after infection.
    • Tip-to-Target Distance Effect on Irradiance Delivered by Dental Curing Lights

      Klein, Laura; Rueggeberg, Fred; Dentistry (2020-02)
      Dental light curing units (LCUs) are often evaluated using exitance irradiance values. These values do not predict irradiance levels observed at common working distances. This project categorized LCUs by the tip-to-target distances where exitance irradiance dropped by 50%.
