Monte Carlo calculation of the response matrix of a Bonner spheres spectrometer
(Sociedad Argentina de Radioprotección, 2008-10)
The Bonner spheres spectrometer is utilized to estimate the neutron spectrum of neutrons from
thermal up to several MeV neutrons. Its response is increased to few GeV neutrons by introducing large Z
materials as inner ...
Pro-oxidant status and matrix metalloproteinases in apical lesions and gingival crevicular fluid as potential biomarkers for asymptomatic apical periodontitis and endodontic treatment response
(2012)
Background: Oxidative stress and matrix metalloproteinases -9 and -2 are involved in periodontal breakdown,
whereas gingival crevicular fluid has been reported to reflect apical status. The aim of this study was ...
Expression of proteins in the extracellular matrix of pulp tissue in human primary teeth during physiologic root resorption
(QUINTESSENCE PUBLISHING CO INC, 2009)
Objectives: To analyze the expression of tenascin, fibronectin, collagens I and III, osteonectin, and bone morphogenetic protein 4 (BMP4) in the extracellular matrix of pulp tissue in primary teeth during physiologic root ...
Site response analysis using one dimensional equivalent linear method and Bayesian filtering
(Elsevier, 2017)
Site response analysis is crucial to define the seismic hazard and distribution of damage during earthquakes.
The equivalent-linear (EQL) is a numerical method widely investigated and used for site response
analysis. ...
Multi-energy calibration applied to atomic spectrometry
(2017-08-22)
Multi-energy calibration (MEC) is a novel strategy that explores the capacity of several analytes of generating analytical signals at many different wavelengths (transition energies). Contrasting with traditional methods, ...
In situ detection of matrix metalloproteinase-9 (MMP-9) in gingival epithelium in human periodontal disease
(2004)
BACKGROUND AND OBJECTIVE:
As the periodontal lesion develops, the junctional epithelium migrates apically in conjunction with the dissolution of the most coronal Sharpey's fibers. Because matrix metalloproteinase-9 (MMP-9) ...
Effects of platelet-rich and -poor plasma on the reparative response of gingival fibroblasts
(2012)
Objectives: Although platelet-rich plasma (PRP) has been proposed as a therapeutic tool to
enhance wound repair, the cellular and molecular mechanisms stimulated by this agent are still not
completely understood. The ...
MICROFIBRILS - NEGLECTED COMPONENTS OF PRESSURE-BEARING TENDONS
(Gustav Fischer Verlag JenaJenaAlemanha, 1994)
Platelets Regulate Pulmonary Inflammation and Tissue Destruction in Tuberculosis
(American Thoracic Society, 2018)
RATIONALE: Platelets may interact with the immune system in tuberculosis (TB) to regulate human inflammatory responses that lead to morbidity and spread of infection. OBJECTIVES: To identify a functional role of platelets ...
