The systemic inflammatory response to dental plaque
… the systemic inflammatory responses to dental plaque, and assess racial differences in these responses; 2) determine whether dental plaque accumulation causes bacteremia and subsequent systemic responses following toothbrushing. Additionally, a laboratory study was conducted to examine the …

Detection of periodontal bacteria in atherosclerotic plaque
… bacterial species present in atherosclerotic plaque tissue from the carotid artery. Immunohistological examination of the atherosclerotic plaque tissue revealed widespread localisation of the bacterial cell wall constituent peptidoglycan (PGN). Targeted PCR amplification of the 16S rRNA gene …

Classification of atherosclerotic plaque vulnerability by mechano-radiomics
… resonance (MR) images can help evaluate carotid plaque vulnerability better than conventional MR methods. Hemodynamic forces have long been associated with the destabilization of developed plaques near regions of complex blood flow e.g., the carotid bifurcation, which results in high wall shear …

A Novel Quantitative Mechanical Test of Atherosclerotic Plaque Stability
<p>Atherosclerotic plaque rupture is a major cause of myocardial infarction and stroke. The adhesive strength of the bond between the plaque and the vascular wall, measured as local energy release rate, G, was used for quantitative plaque stability estimation in mouse models. Towards the long-range …

Dreidimensionale Struktur- und Vitalitätsverteilung oraler bakterieller Biofilme (dentaler Plaque)
… Parameter "Vitalität" und "Dicke" der dentalen Plaque zu untersuchen. Hierfür wurden die Methoden der Vitalfluoreszenztechnik und der konfokalen Laser-Scanning-Mikroskopie (CLSM) kombiniert. <br>In einem Vorversuch wurde die Färbetechnik, die bei "abgekratzten" Biofilmen bereits etabliert war …

Analysis of the Clear Plaque Phenotype of the Bacteriophage HK75
… a suitable host. However, HK75 only forms clear plaques and thus appears to be defective in its ability to form lysogens. Based on published analyses of other lambdoid phages, a clear plaque phenotype is commonly due to a mutation in one of 5 phage genes: <i>cI, cII, cIII, int, xis</i> or the …

A Fluid Structure Interaction Model Of Intracoronary Atherosclerotic Plaque Rupture
Plaque rupture with superimposed thrombosis is the primary cause of acute coronary syndromes of unstable angina, myocardial infarction and sudden death. Although intensive studies in the past decade have shed light on the mechanism that causes unstable atheroma, none has directly addressed the …
-
Three-dimensional Quantitative Magnetic Resonance Imaging of Carotid Atherosclerotic Plaque
… morphological characteristics of atherosclerotic plaque such as a thin fibrous cap, large lipid-rich necrotic core, intraplaque haemorrhage and ulceration have shown correlations with subsequent clinical events. High resolution, multi-contrast magnetic resonance imaging (MRI) can qualitatively …

The role of lipoproteins in vascular calcification and plaque stabilisation
… (VC) is a feature of atherosclerotic plaques and is associated with co-morbidities such as diabetes and chronic kidney disease. While its presence is used by cardiologists to identify higher risk patients, increasing data suggests that the morphology of calcification is also important …

Imaging atherosclerotic plaque inflammation with [18F]- fluorodeoxyglucose positron emission tomography
… the pathogenesis and outcome of atherosclerosis. Plaques containing numerous inflammatory cells, particularly macrophages, have a high risk of rupture, whereas those with fewer inflammatory cells are at lower risk. The current ‘gold standard’ technique for imaging atherosclerosis is x-ray contrast …

DNA-DNA Checkerboard Hybridization to Identify Bacteria in Human Plaque Samples
… the presence of specific bacteria in human plaque samples is superior to the commonly used anaerobic cultural procedures. Some periodontal pathogens are either uncultivable or very difficult to grow, such as<em> Prevotella intermedia, P. nigrescens</em>, and <em>Eubacterium brachy</em>. …

The Effect of Dental Plaque Accumulation on Secretory IgA in Saliva
… whether there is a correlation between dental plaque accumulation , parotid and whole secretory IgA (S-IgA) concentrations and minute secretion rates of S-IgA over a six week period. Eighteen healthy, male freshmen dental students were instructed to refrain from oral hygiene care for six weeks. …

Quantifying Atherosclerosis: IVUS Imaging For Lumen Border Detection And Plaque Characterization
… understand progression of such a disease, detect plaques at risks (vulnerable plaques), and treat them selectively to prevent mortality and immobility. Consequently, several imaging modalities have been developed and among them intravascular ultrasound (IVUS) has been of particular interest since …

Characterization of native and bypass human coronary artery plaque deposits from the same heart: investigation of the chemical form of calcium in human coronary artery plaque deposits
… research, differences between native and bypass plaque deposits from the same heart were examined. In addition, the crystalline and the amorphous plaques within these native and bypass vessels were characterized. The techniques used to characterize the deposits included inductively coupled plasma …

Analyse vibroacoustique de la plaque raidie avec les éléments finis hiérarchiques trigonomériques
… le comportement acoustique et vibratoire d'une plaque munie de raidisseurs. Les plaques raidies sont à la base de plusieurs structures dans les dommaines naval et aéronautique entre autres. La compréhension des phénomènes vibroacoustiques est essentielle. En effet, les vibrations peuvent causer …

Fibromodulin and Dystrophin in Atherosclerosis: Novel roles for extracellular matrix in plaque development
… cause is atherosclerosis, and in atherosclerotic plaque progression the structure, composition and integrity of a dynamic extracellular matrix (ECM) is one very important factor. This thesis discusses the importance of the connection between the ECM and cells for atherosclerotic lesion …
