ABSTRACT Introduction: Zirconia is classified by the mole percentage of yttria contained in the zirconia. The most strong and opaque material contains 3 mol % yttria, intermediate strength and opacity contain 4 mol %, and whereas 5 mol % is the weakest but most translucent zirconia. Refined zirconia powder is pressed into a mold to form a disc which is then milled to form a restoration. Post milling of sintered zirconia restorations is necessary to obtain final mechanical and physical properties of the restoration. Traditionally conventional sintering cycles required 6-8 hours to sinter. Whereas, fast sintering cycles have been have …
Molecular Analysis Of Streptococcus Mutans Genetic Diversity For The Epidemiological Study Of Oral Disease, Stephanie Stahlbuhk Momeni
Molecular Analysis Of Streptococcus Mutans Genetic Diversity For The Epidemiological Study Of Oral Disease, Stephanie Stahlbuhk Momeni

Dental caries is chronic global infectious disease. Streptococcus mutans are most frequently associated with dental caries. The goal of this work is to use molecular genotyping methods to investigate the genetic diversity and evidence for transmission of S. mutans for the epidemiological study of dental caries. It was first necessary to validate methods proposed in this study including choice of selective media, choice of multilocus sequence typing (MLST) scheme, and the frequency of clonality. Analysis included 13,906 S. mutans isolates obtained from oral samples collected from children and their household members in an 8-year longitudinal epidemiological study. Two genotyping methods …
Identification, Molecular Cloning And Characterization Of Transmitted/Founder Hiv-1 Subtype A, D And Ad Viruses And Envelope Glycoproteins, Joshua Baalwa

A precise molecular identification of transmitted/founder (T/F) HIV-1 genomes responsible for productive infection in humans can be an enabling strategy for elucidating mechanisms of virus transmission, immunopathogenesis and prevention. Previously, we reported a single genome sequencing approach, which when combined with a mathematical model of early random virus diversification, allowed for an unambiguous identification of T/F HIV-1 subtype B and C envelope (env) genes. Here, we apply this method to the identification and molecular cloning of full-length HIV-1 genomes and env genes of the less well-studied, but nonetheless important, HIV-1 subtypes A and D. Twelve subtype A (n=5), D (n=5) …
