The crushing truth about glass ionomer restoratives: exposing the standard of the standard
(Elsevier, 2012)Objectives: The compressive fracture strength (CFS) test is the only strength test for glass ionomers (GIs) in ISO 9917-1: 2003. The CFS test was the subject of much controversy in 1990 and has been challenged over its ... -
Cuspal deflection and microleakage in premolar teeth restored with bulk-fill flowable resin-based composite base materials
(Elsevier, 2012)Objectives: To assess the cuspal deflection and cervical microleakage of standardised Class II cavities incrementally filled with a dimethacrylate RBC or bulk-fill flowable RBC bases. Methods: Twenty-four sound upper ... -
The deformation and strength of a dental ceramic following resin-cement coating
(2011)Objectives: The hypothesis tested was that processing, pre-cementation and cementation techniques can modify the profilometrically measured deformation of a ceramic. Methods: Three-point flexural moduli of a resin-cement ... -
Deletion of the Candida albicans TLO gene family using CRISPR-Cas9 mutagenesis allows characterisation of functional differences in ¿-, ß- and ¿- TLO gene function.
(2023)The Candida albicans genome contains between ten and fifteen distinct TLO genes that all encode a Med2 subunit of Mediator. In order to investigate the biological role of Med2/Tlo in C. albicans we deleted all fourteen TLO ... -
A dentifrice containing salivary enzymes and xylitol exhibits superior antimicrobial activity in vitro against adherent Streptococcus mutans compared to a chlorhexidine dentifrice.
(2023)Human saliva contains natural antimicrobial enzymes. In this in-vitro study, we evaluate the antimicrobial activity of a dentifrice containing a salivary enzyme complex (SEC) with xylitol versus a standard 0.12% chlorhexidine ... -
DETECTION OF mecC-POSITIVE Staphylococcus aureus (CC130-MRSA-XI) IN DISEASED EUROPEAN HEDGEHOGS (Erinaceus europaeus) IN SWEDEN
(2013)Recently, a novel mec gene conferring beta-lactam resistance in Staphylococcus aureus has been discovered. This gene, mecC, is situated on a SCCmec XI element that has to date been identified in clonal complexes 49, 130, ... -
DETECTION OF STAPHYLOCOCCAL CASSETTE CHROMOSOME mec Type XI ENCODING HIGHLY DIVERGENT mecA, mecI, mecR1, blaZ and ccr GENES IN HUMAN CLINICAL CLONAL COMPLEX 130 METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS
(2011)Methicillin resistance in staphylococci is mediated by penicillin binding protein 2a (PBP2a) encoded by mecA on mobile staphylococcal cassette chromosome mec (SCCmec) elements. In this study two clonal complex (CC) 130 ... -
Development of Wireless Bruxism Monitoring Device Based on Pressure Sensitive Polymer
(Elsevier, 2010)A wireless pressure sensing bite guard has been developed for monitoring the progress of bruxism (teeth grinding during sleep); as well as protecting the teeth from damages. For sensing the pressure effectively in the ... -
Differential filamentation of Candida albicans and C. dubliniensis is governed by nutrient regulation of UME6 expression
(2010)Candida dubliniensis is closely related to C. albicans, however it is responsible for fewer infections in humans and is less virulent in animal models of infection. C. dubliniensis forms fewer hyphae in vivo and this may ... -
DIFFERENTIAL FILAMENTATION OF CANDIDA ALBICANS AND C. DUBLINIENSIS IS GOVERNED BY NUTRIENT REGULATION OF UME6 EXPRESSION
(2010)Candida dubliniensis is closely related to Candida albicans; however, it is responsible for fewer infections in humans and is less virulent in animal models of infection. C. dubliniensis forms fewer hyphae in vivo, and ... -
DIFFERENTIAL REGULATION OF THE TRANSCRIPTIONAL REPRESSOR NRG1 ACCOUNTS FOR ALTERED HOST CELL INTERACTIONS IN CANDIDA ALBICANS AND CANDIDA DUBLINIENSIS
(2007)Candida dubliniensis is genetically closely related to C. albicans, but causes fewer infections in humans and exhibits reduced virulence and filamentation in animal models of infection. We investigated the role of the ... -
DIFFERENTIAL REGULATION OF THE TRANSCRIPTIONAL REPRESSOR NRG1 ACCOUNTS FOR ALTERED HOST CELL INTERACTIONS IN CANDIDA ALBICANS AND CANDIDA DUBLINIENSIS
(Blackwell Publishing, 2007-09)Candida dubliniensis is genetically closely related to C. albicans, but causes fewer infections in humans and exhibits reduced virulence and filamentation in animal models of infection. We investigated the role of the C. ... -
DIFFERENTIAL VIRULENCE OF CANDIDA ALBICANS AND CANDIDA DUBLINIENSIS: A ROLE FOR TOR KINASE?
(2011)Candida albicans and Candida dubliniensis are two very closely related species of pathogenic yeast. C. albicans is the most prevalent species in the human gastrointestinal tract and is responsible for far more opportunistic ... -
DISINFECTION PROCEDURES: THEIR EFFICACY AND EFFECT ON DIMENSIONAL ACCURACY, SURFACE QUALITY AND SURFACE DETAIL REPRODUCTION OF AN IRREVERSIBLE HYDROCOLLOID IMPRESSION MATERIAL
(2011)Objectives: This study investigated the antibacterial efficacy and effect of 0.55% ortho-phthalaldehyde (Cidex OPA?) and 0.5% sodium hypochlorite (NaOCl) on the dimensional accuracy and surface quality of gypsum casts ... -
Distribution of SCCmec-associated phenol-soluble modulin in staphylococci
(2012)The recently described phenol-soluble modulin PSM-mec was detected in S. aureus, S. epidermidis, S. fleuretti, S. hominis, S. pseudintermedius, S. saprophyticus, S. simulans and S. vitulinus from different hosts (humans, ... -
DNA MICROARRAY GENOTYPING AND VIRULENCE AND ANTIMICROBIAL RESISTANCE GENE PROFILING OF METHICILLIN-RESISTANT Staphylococcus aureus BLOODSTREAM ISOLATES FROM RENAL PATIENTS
(2011)Thirty-six methicillin-resistant Staphylococcus aureus (MRSA) bloodstream isolates from renal patients were genetically characterized by DNA microarray analysis and spa typing. The isolates were highly clonal, belonging ... -
Does fluoride exposure impact on the human microbiome?
(2023)Fluoride is added to drinking water in some countries to prevent tooth decay (caries). There is no conclusive evidence that community water fluoridation (CWF) at WHO recommended concentrations for caries prevention has any ...
