BACKGROUND The aim of study was to evaluate the application of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride regarding their effect on the shear bond strength (SBS), bond failure pattern of brackets using the adhesive remnant index (ARI) and assessing the quality of enamel surface using the enamel damage index (EDI). MATERIAL AND METHODS Sixty extracted premolar tee...

The mechanism of arrhythmogenicity in heart failure remains poorly understood. We examined the relationship between electrical abnormalities and ventricular arrhythmia by using experimental heart failure models. Sixty unipolar electrograms were recorded from the entire cardiac surface in control dogs (n = 13) and pacing-induced heart failure dogs (n = 16). In failing hearts, activation time (AT...

Cerebral autoregulation adjusts cerebrovascular resistance in the face of changing perfusion pressures to maintain relatively constant flow. Results from several studies suggest that cardiac output may also play a role. We tested the hypothesis that cerebral blood flow would autoregulate independent of changes in cardiac output. Transient systemic hypotension was induced by thigh-cuff deflation...

BACKGROUND Acute respiratory illness (ARI) accounts for a large proportion of all visits to pediatric health facilities. Quantitative real-time polymerase chain reaction (qPCR) analyses allow sensitive detection of viral nucleic acids, but it is not clear to what extent specific viruses contribute to disease because many viruses have been detected in asymptomatic children. Better understanding ...

INTRODUCTION Acute respiratory infections (ARI) are the leading cause of pediatric morbidity and mortality worldwide. Information about etiological agents of ARI in developing countries is still limited. METHODOLOGY Throat swabs collected from children hospitalized with ARI between December 2009 and May 2010 were investigated for Chlamydophila pneumoniae, Mycoplasma pneumoniae, and influenza ...

BACKGROUND Self-collection of nasal swabs could improve the timeliness of influenza virus detection in older adults. OBJECTIVES Measure the acceptability, adequacy, timeliness, and validity of self-collected nasal swabs among adults >65 years in Thailand. METHODS Our evaluation consisted of two parts: a one-month study among randomly selected, community-dwelling older adults to simulate com...

Introduction: The bonding process of the brackets to enamel has been a critical issue in orthodontic research. The purpose of this study was to evaluate the shear bond strength of 3 light-cured adhesives (transbond XT, Z250, light bond). Materials &Methods: In this study sixty extracted human premolars were collected and randomly divided into 3 test groups. All teeth were etched by 37% phosp...

Background The current study aims to describe the demographical and clinical characteristics of elderly nursing home (NH) residents with acute respiratory infections (ARIs) during four winter seasons (2013/2014-2016/2017), as well as the microbiological etiology of these infections. Methods Seventeen NHs with at least one ARI resident in Corsica, France, were included. An ARI resident was def...
