1. Validation of a classification and scoring system for the diagnosis of laryngeal and pharyngeal squamous cell carcinomas by confocal laser endomicroscopy
Abstract Introduction: Confocal laser endomicroscopy is an optical imaging technique that allows in vivo, real-time, microscope-like images of the upper aerodigestive tract’s mucosa. The assessment of morphological tissue characteristics for the correct differentiation between healthy and malignant suspected mucosa requires strict evaluation criteria. Ob

2. Comparative effects of final canal irrigation with chitosan and EDTA
Abstract Chitosan is a natural, biocompatible chelating substance with potential for dental use. This study compared the effects of final canal irrigation with chitosan and EDTA on dentin microhardness, sealer dentin tubules penetration capacity, and push-out strength. Methodology: Fifty canine roots were distributed according to the final irrigation protoc

3. A new species of Clausidium Kossmann, 1874 (Crustacea, Copepoda, Cyclopoida, Clausidiidae) associated with ghost shrimps from Iran
Abstract A new species of the Clausidium Kossmann, 1874 copepods is described, illustrated and provided by Confocal Laser Scanning Microscope photo on the basis of specimens from the gill chamber of Callianidea typa H. Milne Edwards, 1837 from the Iranian coast of the Persian Gulf. Clausidium persiaensis sp. nov is unique in the possession of a fine spine on

4. Resin-based sealer penetration into dentinal tubules after the use of 2% chlorhexidine gel and 17% EDTA: in vitro study
Aim: To evaluate, by confocal laser scanning microscopy (CLSM), the influence of 17% EDTA final irrigation on the penetration of an endodontic resin-based sealer into dentinal tubules after use of 2% chlorhexidine gel. Methods: Forty extracted bovine incisors were instrumented according to the groups: G1 - root canal preparation with 2% chlorhexidine gel (n=

5. Desenvolvimento de um microscópio confocal de varredura laser para caracterização topográfica de superfícies / Development of a microscope confocal scanning laser surface characterization of surveying
Este trabalho tem como objetivo desenvolver uma técnica de caracterização topográfica de superfícies. Desta forma, foi desenvolvido um Microscópio Óptico Confocal de Varredura Laser, alcançando resolução submicrométrica. A amostra é varrida por laser e sua imagem é virtualmente montada ponto a ponto pela detecção da intensidade da reflexão da

6. Avaliação da vasculatura pulmonar na esclerose sistêmica / Evaluation of pulmonary vasculature in systemic sclerosis
A lesão pulmonar é a principal causa de morte da Esclerose Sistêmica (ES), e as alterações principais são: o acometimento intersticial e o vascular. No presente estudo analisamos através do microscópio confocal a laser 40 artérias pulmonares de pequeno e médio calibre de pacientes com ES e 16 controles. Medimos a área do lúmen, a área total do v

7. Análise "in vitro" da resistência adesiva de sistemas adesivos autocondicionantes com o substrato dentinário após a desproteinização dentinária
The purpose of this study was to evaluate in vitro the bond strength of the self etch adhesive systems One Coat SE Bond, Self Etch Bond, and XENOIII with the dentin substrate, by means of the microtensile bond strength test, after dentin deproteinization. The conventional adhesive system Adper Single Bond/3M-ESPE was used as group control. Thirty five human

8. Embryo sac development in yellow passion fruit Passiflora edulis f. flavicarpa (Passifloraceae)
The yellow passion fruit, Passiflora edulis f. flavicarpa, is one of the most important Brazilian fruit crops. It is an allogamous, diploid, and self-incompatible species. It has hermaphrodite, solitary flowers, located in the leaf axils and protected by leaf bracts. The flower has an androgynophore, which is a straight stalk supporting its reproductive part

9. Implementação de um sistema de eletroforese capilar com detecção de fluorescência induzida por laser
A capillary electrophoresis system using laser induced fluorescence detection is described. A Raman system equipped with a microscope has been used to focus the laser beam on the capillary giving a lateral resolution of 1.5 mm. The fluorescence signal of the analyte (ZnPcTS - tetrasulfonated zinc-phthalocyanine) was collected by the microscope objectives and

10. Lateral diffusion measurement at high spatial resolution by scanning microphotolysis in a confocal microscope.
Fluorescence photobleaching methods have been widely used to study diffusion processes in the plasma membrane of single living cells and other membrane systems. Here we describe the application of a new photobleaching technique, scanning microphotolysis. Employing a recently developed extension module to a commercial confocal microscope, an intensive laser b

11. Differential trafficking of live and dead Mycobacterium marinum organisms in macrophages.
We characterized the Mycobacterium marinum phagosome by using a variety of endocytic markers to follow the path of the bacteria through a mouse macrophage cell line. Using a laser confocal microscope, we found that the majority of viable M. marinum cells were in nonacidic vacuoles that did not colocalize with the vacuolar proton ATPase (V-ATPase), the calciu

12. Line-scanning microphotolysis for diffraction-limited measurements of lateral diffusion.
Fluorescence microphotolysis was combined with confocal laser-scanning microscopy to yield a method, herein referred to as line-scanning microphotolysis (LINESCAMP), for the measurement of molecular transport at a lateral resolution of approximately 0.34 microns and a temporal resolution of approximately 0.5 ms. A confocal microscope was operated in the line
