Care And Maintenance Of Dental Restorations, Ibeth Erazo Dec 2020

Care And Maintenance Of Dental Restorations, Ibeth Erazo

Publications and Research

Contributing to the longevity of the restoration by minimizing the effects of surface corrosion, maintaining the esthetic appearance and the smooth surface characterization, and contributing to gingival health by lessening the potential for plaque retention are the principal reasons for taking care of dental restorations. However, during oral hygiene routine procedures and prevention treatments, these desired effects are not always achieved. In many cases, the restorative materials are not identified in a patient’s record leading to damage during oral hygiene performance by dental professionals. Therefore, it is important to be able to recognize the different restorative materials and employ the …

Regulation Of Transposable Elements By Tumor Suppressor Protein 53, Andrew J. Rosato Dec 2020

Regulation Of Transposable Elements By Tumor Suppressor Protein 53, Andrew J. Rosato

Theses

Multiple transposable elements have been identified by colocalization analysis that display a strong predicted regulatory relationship with p53 associated peaks. RNA-Seq was used to identify differentially expressed transposable elements. ChIP-Seq was used to identify peaks representing transcription factor binding sites in p53 activated cells. The results of both experiments were then combined in a colocalization analysis identifying transposable element locations that were both differentially regulated and located near p53 associated peaks. The colocalization of ChIP-Seq and RNA-Seq analyses allows for the verification of p53’s regulatory role in the expression of transposable elements across the genome. A Monte Carlo simulation was …

Between The Visceral And The Lie : Lessons On Teaching Violence, Brian Gibbs Dec 2020

Between The Visceral And The Lie : Lessons On Teaching Violence, Brian Gibbs

Intersections: Critical Issues in Education

Drawing from two qualitative case studies, one researching how teachers teach about war to the children of soldiers and the other examining how teachers teach lynching near historic lynching sites, this critical phenomenological study weighs how much horror and how much hope should be taught if the aim of the instruction is a liberating education. The author argues that a balance of both is necessary. Students cannot be left in the hopelessness of knowledge alone but must be taught how to engage their world with the possibility of making change.
