Functional Activities And Immunohistochemical Cellular Distribution Of Glutathione S-Transferases In Normal, Dysplastic, And Squamous Cell Carcinoma Human Oral Tissues., Peter J. Giannini, Mark A. Morse, Christopher M. Weghorst, Ping Pei, Susan R. Mallery Jan 2008

Functional Activities And Immunohistochemical Cellular Distribution Of Glutathione S-Transferases In Normal, Dysplastic, And Squamous Cell Carcinoma Human Oral Tissues., Peter J. Giannini, Mark A. Morse, Christopher M. Weghorst, Ping Pei, Susan R. Mallery

Journal Articles: College of Dentistry

Clinical data show a strong correlation between tobacco and alcohol use and the development of oral squamous cell carcinoma (SCC). While this association implies that the oral mucosa actively metabolizes carcinogens, there is little information which depicts the carcinogen metabolizing enzymes within the oral cavity. Glutathione S-transferases (GSTs) primary function is to detoxify carcinogens by increasing their water solubility, GSTs represent key carcinogen metabolizing enzymes. Notably, individuals with a null phenotype for certain GST isoforms are at an increased risk to develop cancer. This study investigated the function and distribution of GSTs in human oral tissues. Our results from this …

Enzymatic Processing Of Amelogenin During Continuous Crystallization Of Apatite, Vuk Uskoković, M.-K. Kim, W. Li, S. Habelitz

Pharmacy Faculty Articles and Research

Dental enamel forms through a protein-controlled mineralization and enzymatic degradation with a nanoscale precision that new engineering technologies may be able to mimic. Recombinant fulllength human amelogenin (rH174) and a matrix-metalloprotease (MMP-20) were employed in a pHstat titration system that enabled a continuous supply of calcium and phosphate ions over several days, mimicking the initial stages of matrix processing and crystallization in enamel in-vitro. Effects on the self-assembly and crystal growth from a saturated aqueous solution containing 0.4 mg/ml rH174 and MMP-20 with the weight ratio of 1:1000 with respect to rH174 were investigated. A transition from nanospheres to fibrous …

Friction Produced By Esthetic Brackets With Varying Ligation, Christine Knox Abenoja Jan 2008

Friction Produced By Esthetic Brackets With Varying Ligation, Christine Knox Abenoja

All ETDs from UAB

Controlling friction is an important aspect of orthodontics because it allows more predictable tooth movement with less anchorage loss. Friction at the bracket/archwire/ligation interface can reduce the force available for desired tooth movement. Initial stages of orthodontic treatment depend on the ability of the archwire to slide freely through the bracket, making friction an important aspect of all orthodontic brackets in the early phases of orthodontic treatment. The purpose of the present in vitro study was to measure the force to move esthetic brackets over an archwire using different ligation methods. A stainless steel model reproducing the maxillary right dentition …

Variability Of Two Sampling Methods In Plaque Samples, Kuei C. Hsu Jan 2008

Variability Of Two Sampling Methods In Plaque Samples, Kuei C. Hsu

All ETDs from UAB

Introduction: Dental caries remain the most common infectious disease in children, and is in fact, on the rise in the U.S. among 2 to 5 year olds. Among hundreds of oral bacteria, mutans streptococci (MS) are considered the major species associated with dental caries. Studies have shown that increased MS in saliva or plaque is an important indicator for caries. The use of standard plate count (SPC) from plaque samples particularly yield variable quantitative results because of complexities of sample collection and processing. Objectives: This study was undertaken to determine collection reproducibility in plaque samples from permanent first molars using …
