Loma Linda University Electronic Theses, Dissertations & Projects

Objectives: To examine adolescent patient attitudes and understanding of basic orthodontic treatment information presented in either comic book format or plain text.

Methods: This study involved subjects undergoing orthodontic treatment at the Loma Linda University Graduate Orthodontic Clinic. Subjects were randomly assigned to two groups: Group 1 subjects received an orthodontic comic book to read, while Group 2 subjects received a plain text information sheet containing the same pertinent information as Group 1. All subjects completed an identical survey regarding the material they read. Statistical analysis consisted of a chi-square test at α = 0.05 to determine potential …

Since the 1960s federal and local initiatives have been put in place to decrease the staggering socioeconomic disparities in the United States. Considerable debate has been fueled by the conception of adequate solutions to address the employment crisis (Kregel, 2011). Despite the increase in supportive services made available to the public, low-income families continue to face distinct challenges that limit employment and vocational opportunities (Athreya & Romero, 2015; Crouter & Booth, 2014; Presser, 2014), a situation particularly true for ethnic minorities navigating the systems of employment in the US (Fullerton & Anderson 2013; Mazumder, 2011). The purpose of this study …

Synthesis And Characterization Of Hemocompatible Antibiotic Nanoparticles, Elvin Muhindo Walemba

Loma Linda University Electronic Theses, Dissertations & Projects

Porphyromonas gingivalis is a causative agent of periodontal disease and a risk factor for cardiovascular disease. Novel treatment of periodontal disease using nanomaterials can supplement or replace the use of antibiotics and mechanical debridement. Nanomaterials can be optimized for effectiveness and specificity and minimum toxicity. Synthesized Ag nanoparticles stabilized in Pluronic F127 were used to produce bimetallic core/shell Ag/Au nanoparticles with optimized Ag+ release and reduced toxicity. We tested the F127-stabilized nanoparticles for their antimicrobial activity and hemocompatibility in planktonic bacteria and citrated whole blood, respectively. Both Ag and Ag/Au bimetallic nanoparticles inhibited P. gingivalis W83 growth. We then evaluated …
