Identification Of Virulence Determinants For Streptococcus Sanguinis Infective Endocarditis, Lauren Turner

Theses and Dissertations

Streptococcus sanguinis is the second most common causative agent of bacterial infective endocarditis (IE). Risk of S. sanguinis IE is dependent on pre-disposing damage to the heart valve endothelium, which results in deposition of clotting factors for formation of a sterile thrombus (referred to as vegetation). Despite medical advances, high mortality and morbidity rates persist. Molecular characterization of S. sanguinis virulence determinants may enable development of prevention methods. In a previous screen for S. sanguinis virulence determinants by signature-tagged mutagenesis (STM) an attenuated mutant was identified with a transposon insertion in the nrdD gene, encoding an anaerobic ribonucleotide reductase. Evaluation …

Modeling Pure Vasogenic Edema In The Rat Brain, Charles Nottingham

Theses and Dissertations

Targeted drug delivery to the brain is difficult to achieve using conventional techniques, largely due to the blood-brain barrier’s (BBB) impediment to drug diffusion into the brain parenchyma. In response, development of convection-enhanced delivery (CED) offers the ability to circumvent the BBB and target specific areas of the brain. Predictability of infusate movement in pathological brain states during CED will maximize the effectiveness of this treatment, and therefore modeling of infusate movement must be characterized. Previous work from our lab effectively modeled CED in rats using the middle carotid artery occlusion model of cytotoxic edema. However, previous models examined for …

Physiological And Molecular Characterization Of Genetic Competence In Streptococcus Sanguinis, Alejandro Rodriguez

Theses and Dissertations

The ability of bacteria to assimilate free DNA from the environment is known as competence. Though many studies have focused on competence regulation in Streptococcus pneumoniae and Streptococcus gordonii, Streptococcus sanguinis has yet to be examined. Physiological characterization of competence in S. sanguinis strain SK36 and its comC mutant, JFP41, led to the genome-wide transcriptional analysis of cells induced to competence via addition of competence-stimulating peptide (CSP). A total of 128 genes were induced at least 2-fold, 74 of which were classified as either “early” or “late” based on their induction patterns. Expression patterns were verified using qRT-PCR. This study …

The Response Of Hn4 Cells To Porphyromonas Gingivalis Dna, Cheyanne Warren

Theses and Dissertations

Periodontal disease is one of the most common human diseases. Bacteria trigger the onset and progression of the disease and among them Porphyromonas gingivalis has been demonstrated to be a major etiologic agent. Although the interaction of the bacterium with the host is of major importance for the understanding of the disease mechanisms, both the host as well as the pathogen components involved in the interaction remain poorly understood. One of the bacterial components capable of eliciting a host response is unmethylated CpG DNA motifs found in bacteria. Thus, the first aim was to determine the response of oral epithelial …

Contamination Of Dental Waterlines: Efficacy Of Seven Waterline Treatments And Three In-Office Bacteria Test Kits, Adam Davis

Theses and Dissertations

This study compared seven dental unit water line (DUWL) treatments and three in-office bacteria test kits. Sodium hypochlorite (NaOCl) 1:10 in tap water weekly; 3 drops of NaOCl in 1 liter of water; Dentapure® DP 40; ICX™ tablet; Sterilex® Ultra powder; Lines™; and Selective Micro® Dental-Clean. Traditional culture technique was compared to HPC Dental Sampler; Aquasafe™ Dental Unit Water Line Test Kit; and Bacteria in Water Test Kit. Eight dental units in the Virginia Commonwealth University Graduate Endodontic Clinic were randomly assigned treatment regimens. Samples were taken weekly initially and after flushing for 1 minute. In conclusion NaOCl hypochlorite 1:10 …

Communication Skills Instruction Utilizing Interdisciplinary Peer Teachers: Program Development And Student Perceptions, Sharon K. Lanning, Sonya L. Ranson, Rita M. Willett

Periodontics Publications

Lack of curricular time, faculty time, and funding are potential limitations for communication skills training in dentistry. Interdisciplinary collaboration amongst health care faculties could address these limitations. This article describes the development, implementation, and student perceptions of a communication skills program in dentistry. The program has four components: Knowledge, Observation, Simulation, and Experience (KOSE) and spans over the second and third years of dental school. KOSE allows students to obtain knowledge of and observe effective communication skills and practice these skills in the simulated and nonsimulated environment. A key feature of KOSE is the utilization of fourth-year medical and dental …

The Use Of Implants Vs. Endodontics: Practitioner Attitudes In 2007, Gardiner Mckay Packer

Theses and Dissertations

The purpose of this study was to determine what factors influence dentists when deciding whether to place an implant or perform endodontic retreatment. Null hypothesis: Dentists today are no more likely to place an implant than to perform endodontic retreatment. A twelve-item questionnaire was mailed to 525 general dentists and specialists who are members of the Richmond Dental Society. Response rate was 61.9%. The questionnaire included items on demographics, practice profile and cases of failing endodontic therapy which participants were asked to consider and chose between endodontic retreatment or implant placement. The relationship between the treatment choices and the characteristics …

Background

Computed tomographic (CT) colonography is a noninvasive option in screening for colorectal cancer. However, its accuracy as a screening tool in asymptomatic adults has not been well defined.

Methods

We recruited 2600 asymptomatic study participants, 50 years of age or older, at 15 study centers. CT colonographic images were acquired with the use of standard bowel preparation, stool and fluid tagging, mechanical insufflation, and multidetector-row CT scanners (with 16 or more rows). Radiologists trained in CT colonography reported all lesions measuring 5 mm or more in diameter. Optical colonoscopy and histologic review were performed according to established clinical protocols …

Information-Seeking Behaviors Of Practicing Dental Hygienists In Virginia, Joan Marie Pellegrini

Theses and Dissertations

This study explored how currently licensed, active dental hygiene practitioners in the Commonwealth of \firginia, retrieve, validate and process new knowledge in the discipline which provides a basis for clinical decisions on selection of dental hygiene interventions for patients. The research design was a non experimental, correlational design using mail survey methodology. A self-developed questionnaire was mailed to 500 practicing dental hygienists in the Commonwealth of Virginia. The survey contained questions on demographics of the respondent, current methods of retrieving new information in the discipline, and preferences for information retrieval. The completed surveys that were returned yielded a 52.7% response …
