The Designs Of Miniscrew-Assisted Transpalatal Arch Affect Molar Intrusion, Ornnicha Pooktuantong

Chulalongkorn University Theses and Dissertations (Chula ETD)

Abstract: An anterior open bite is one of the most difficult malocclusions in orthodontic treatment. For such malocclusion, orthodontic miniscrews insertion into both buccal and palatal alveolar regions has been indicated for molar intrusion, but it involves a risk of tooth root injury. To solve the problem, midpalatal miniscrew-attached extension arm (MMEA) is adopted. However, this method causes palatal tipping of the molar because intrusive loads were applied only from palatal side. Currently, transpalatal arch is added to avoid tipping movement, but it induces patient's discomfort. Hence, the objective of this study was to evaluate the loading conditions for maxillary …

Ck2 Phosphorylation Of Human Papillomavirus 16 E2 On Serine 23 Promotes Interaction With Topbp1 And Is Critical For E2 Plasmid Retention Function, Apurva Tadimari Prabhakar

Theses and Dissertations

Human papillomaviruses (HPVs) are the causative agents in most cervical cancers and have been implicated in a rising number of oropharyngeal cancers. HPV positive oropharyngeal cancers have increased significantly over the last two decades with no specific anti-viral therapeutic options for the treatment of HPV diseases. During its lifecycle, HPV16 encoded E2 protein interacts with host cellular factors to regulate viral transcription, replication and genome segregation/retention. Our understanding of the cellular partner proteins that E2 uses to mediate its functions remains incomplete.

Previously, an interaction between E2 and the host protein TopBP1 was identified. In earlier studies, it was also …

Il-36g Cytokine Induction In Oral Epithelial Cells Triggered By Treponema Denticola And Their Role In Chronic Periodontitis, Christopher Blake

Theses and Dissertations

Periodontal disease is a polymicrobial disease affecting 10-15% of the population. Periodontal disease affects the quality of life by reducing mastication and potentially causing tooth loss. Periodontal disease is also linked to more severe, systemic diseases such as cardiovascular disease and rheumatoid arthritis. Development of the diseased state occurs when the plaque biofilm shifts from healthy to dysbiotic. The shift to a dysbiotic biome brings with it a shift in bacterial presence, specifically an increase in gram-negative bacteria, such as T. denticola. T. denticola is a gram-negative, anaerobic spirochete whose relationship with oral epithelial cells is poorly understood. Preliminary data …
