Determination of periodontopathogens in patients with cri du chat syndrome

2013

Objectives: Cri du chat syndrome is a genetic alteration associated with some oral pathologies. However, it has not been described previously any clinical relationship between the periodontal disease and the syndrome. The purpose of this comparative study was to compare periodontopathogenic flora in a group with Cri du chat syndrome and another without the síndrome, to assess a potential microbiological predisposition to suffer a periodontitis. Study Design: The study compared nineteen subjects with Cri du chat Syndrome with a control group of nineteen patients without it. All patients were clinically evaluated by periodontal probing, valuing the pocket depth, the clinical attachmente level…

Effects of photodynamic therapy in periodontal treatment: A randomized, controlled clinical trial

2017

Aim To evaluate the effects of photodynamic therapy (PDT) in the nonsurgical treatment of chronic periodontitis. Materials and methods A randomized, single-blind, controlled, parallel-group clinical trial was performed. Sixty patients were enrolled: 20 healthy controls and 40 patients with periodontitis. The 40 patients were randomized for scaling and root planing (SRP) or SRP+PDT. Periodontal (plaque index, probing depth, clinical recession, clinical attachment level, bleeding on probing, and gingival crevicular fluid volume, corresponding to 381 vs 428 critical sites), microbiological (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema dentico…

Oxidative Stress Parameters in Saliva and Its Association with Periodontal Disease and Types of Bacteria

2015

Objective. To determine the association between oxidative stress parameters with periodontal disease, bleeding, and the presence of different periodontal bacteria.Methods. A cross-sectional study in a sample of eighty-six patients, divided into three groups depending on their periodontal status. Thirty-three with chronic periodontitis, sixteen with gingivitis, and thirty-seven with periodontal healthy as control. Oxidative stress biomarkers (8-OHdG and MDA), total antioxidant capacity (TAOC), and the activity of two antioxidant enzymes (GPx and SOD) were determined in saliva. Subgingival plaque samples were obtained from the deepest periodontal pocket and PCR was used to determine the prese…

Prevalence of fimA genotypes of Porphyromonas gingivalis and other periodontal bacteria in a Spanish population with chronic periodontitis

2012

Objectives: The aim of this study was to determine the prevalence of the different fimA genotypes of Porphyromonas gingivalis in adult Spanish patients with chronic periodontitis, patients with gingivitis and periodontally healthy subjects, and the relationship between these genotypes and other periodontopathogenic bacteria. Study design: Samples of subgingival plaque were taken from 86 patients (33 with chronic periodontitis, 16 with gingivitis, and 37 periodontally healthy) in the course of a full periodontal examination. PCR was employed to determine the presence of the 6 fimA genotypes of Porphyromonas gingivalis (I-V and Ib) and of Aggregatibacter actinomycetemcomitans, Tannerella fors…

Mündliche Kompetenz und Bewusstsein beim unterrichtlichen Fremdsprachenlernen

2014

Das Buch befasst sich mit dem Zusammenspiel von kognitiven, emotionalen und motivationalen Faktoren beim Aufbau von mündlicher Kompetenz in Deutsch als Tertiärsprache bei erwachsenen Italienern. Es stützt sich dabei auf ein interdisziplinäres Vorgehen, das theoretisch erörtert und in seiner Methodenwahl ausführlich dargelegt wird, insbesondere die Videografie sowie intro-/retrospektive Verfahren. Die Ergebnisse der Studie veranschaulichen die Lernprozesse einmal klassenübergreifend, zum anderen erfolgt eine detaillierte Analyse der einzelnen Lernenden. Das Literaturverzeichnis liefert Lehrenden, Studierenden und Forschern eine erschöpfende bibliographische Quelle zu den behandelten Themen.

The think aloud method in studying the translation process

2019

This paper presents a theoretical description of the process-oriented research method in translation studies known as the think aloud method and a case study of an experimental application of think-aloud protocols (TAP). The article begins with a brief description of the relevance of its topic, taking into account the state of current researches in the field of translation studies. A literature review of recent publications where the think aloud method and think-aloud protocols as the principal introspective and retrospective method in different translation studies is given. The shortcomings and advantages of applying the think aloud method are discussed and the ways to optimise the use of …

A new neuraminic acid derivative and three types of glycopeptides isolated from the Cuvierian tubules of the sea cucumber Holothuria forskali

1973

The Cuvierian tubules of Holothuria forskali Della Chiaje, a sea cucumber found in the Adriatic Sea, were investigated with regard to their carbohydrate moieties. From a Pronase digest of these tubules three types of carbohydrate units were isolated and characterized. 1. A high-molecular-weight glycopeptide fraction was shown to contain sulphated polyfucose, galactosamine, a uronic acid and a previously unknown neuraminic acid derivative. The sulphate was shown by i.r. analysis to be present as an O-ester. The carbohydrate unit was linked O-glycosidically to threonine and serine residues in the polypeptide chain. The hitherto unknown neuraminic acid derivative (Hf-neuraminic acid) was resis…
