Examination Of Birth Outcomes With Mode Of Delivery For Breech Presentation, Kelly Marie Arey Jan 2007

Examination Of Birth Outcomes With Mode Of Delivery For Breech Presentation, Kelly Marie Arey

Theses and Dissertations

Introduction: Approximately 3% to 4% of all pregnancies at term will have a fetus with a breech presentation. Studies have shown that the US has almost completely abandoned vaginal delivery for breech presentation through the influence of the "Term Breech Trial" (TBT) which concluded that a policy of planned caesarian section would reduce perinatal mortality, late neonatal mortality, and serious neonatal morbidity by approximately two-thirds for term fetuses. However, the recommendations are still being challenged by others.Objectives: The purpose of the study was to describe who in Virginia is having a vaginal delivery for a breech presentation and to determine …

Concurrent Whitening And Orthodontic Treatment, Jason Thomas Gladwell Jan 2007

Concurrent Whitening And Orthodontic Treatment, Jason Thomas Gladwell

Theses and Dissertations

The aim was to evaluate whether a whitening system, when used during the final stages of orthodontics, would yield results comparable to whitening alone. Patients were assigned to either the control (n=20) or experimental (n=26) groups. At T1, patients were given a ten day supply of Trèswhite™ by Opalescence®, instructions on use, and initial shade determination was made and photographs were taken. At T2 and T3, shade determination was accomplished and updated photographs were taken. Whitening of the teeth occurred in both groups on average, but significantly more whitening was experienced in the experimental group (p < 0.004). An average of 87% of teeth whitened during orthodontic treatment compared to 97% of control teeth (p < 0.01) were judged to be uniform in appearance. In conclusion, the data do not contraindicate the concurrent accomplishment of teeth whitening during orthodontic treatment.

Interactions Of Mtfabh With Its Substrates And Inhibitors Reveal Novel Mechanistic Insights, Sarbjot Singh Sachdeva Jan 2007

Interactions Of Mtfabh With Its Substrates And Inhibitors Reveal Novel Mechanistic Insights, Sarbjot Singh Sachdeva

Theses and Dissertations

Tuberculosis emerged from its grave to be one of the deadliest diseases of the present time after recently developing a synergy with AIDS. A fatty acid condensing enzyme-mtFabH has been proposed to connect the key processes involved in biosynthesis of mycolic acids, an important component of mycobacterial cell wall. It condenses long acyl Coenzymes A (CoA; up to C20CoA) with malonyl Acyl Carrier Protein (ACP) to form the elongated β-ketoacyl-ACP which further undergoes rounds of elongation to form mero-mycolate branch of mature mycolic acids. Owing to its proposed central position in mycolic acid synthesis, mtFabH has attracted considerable attention as …

A Comparision Of Delta-9-Tetrahydrocannabinol Dependence In C57bl/6j Mice And Fatty Acid Amide Hydrolase Knock Out Mice, Brittany Leigh Alice Carlson Jan 2007

A Comparision Of Delta-9-Tetrahydrocannabinol Dependence In C57bl/6j Mice And Fatty Acid Amide Hydrolase Knock Out Mice, Brittany Leigh Alice Carlson

Theses and Dissertations

The idea that humans and laboratory animals can become physically dependent on marijuana or its primary psychoactive constituent, delta-9-tetrahydrocannabinol (THC), is gaining acceptance. However, there are no currently approved pharmacotherapies to treat cannabinoid withdrawal. The objective of this thesis was to evaluate whether elevating endogenous anandamide levels using mice lacking fatty acid amide hydrolase (FAAH), the enzyme responsible for anandamide metabolism, would ameliorate THC dependence. Mice were treated subchronically with a low or high THC dosing regimen and challenged with the CB1 receptor antagonist, rimonabant, to precipitate withdrawal. Following subchronic THC treatment, rimonabant precipitated a significant increase in paw flutters …

Telomerase Inhibition And Sensitization Of Breast Tumor Cells, Kennon R. Poynter Jan 2007

Telomerase Inhibition And Sensitization Of Breast Tumor Cells, Kennon R. Poynter

Theses and Dissertations

Telomerase, a ribonucleoprotein enzyme minimally composed of an RNA template (hTR) and a catalytically active protein subunit (hTERT), synthesizes telomeric repeats onto chromosome ends and is obligatory for continuous tumor cell proliferation, as well as malignant progression of breast cancer cells. Telomerase is an attractive anticancer therapeutic target because its activity is present in over 90% of human cancers, including more than 95% of breast carcinomas, but undetectable in most somatic cells. Traditions chemo- and radio-therapies lack the ability to effectively control and cure breast cancer, in part because residual cells are or become resistant to DNA damaging modalities.While various …
