Spatial variance in the 12-lead ECG and mechanical dyssynchrony
(Springer, 2021-05)
Introduction: Electrical transmission disorders have a deleterious effect on cardiac depolarization, resulting in a disorganized ventricular contraction that reduces global mechanical efficiency; this mechanical dyssynchrony ...
Biomarkers of fluoride in children exposed to different sources of systemic fluoride
(SAGE Publications, 2011)
There has been no comparison between fluoride concentrations in urine and nails of children exposed to different sources of systemic fluoride. The aim of this study was to compare the relationship between fluoride intake ...

Design of variance control charts with estimated parameters: A head to head comparison between two perspectives
(Taylor and Francis Ltd.GB, 2022)
Since parameter estimation degrades chart performance, it is important to design a control chart correctly, that is, taking account of the estimation effects. To this end, two perspectives are available in the literature: ...

Reliability of maximum bite force measurements in age-varying populations
(WILEY-BLACKWELL PUBLISHING, INC, 2009-11-01)
Summary In order for bite forces to be used clinically, they must be reliable. While bite force transducers are accurate and precise during bench tests, widely varying reliabilities of intra-oral bite forces have been ...
Facial asymmetry and genetic ancestry in Latin American admixed populations
(Wiley, 2015)
Fluctuating and directional asymmetry are aspects of morphological variation widely used to infer environmental and genetic factors affecting facial phenotypes. However, the genetic basis and environmental determinants of ...

The short-term effects of diammine silver fluoride on tooth sensitivity: A randomized controlled trial
(SAGE Publications, 2011)
Tooth sensitivity is a common clinical problem. This multi-center randomized clinical trial assessed the effectiveness and safety of topical diammine silver fluoride. From two sites (Lima and Cusco, Peru), 126 adults with ...
