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

4. Do different strains of E. faecalis have the same behavior towards intracanal medications in in vitro research?
Abstract: The aim of this study was to evaluate the antimicrobial action of different endodontic pastes against Enterococcus faecalis ATCC 29212, isolated from the urinary tract, and compare the action with E. faecalis ATCC 4083, isolated from the root canal. For this purpose, dentin blocks were infected for 21 days with both bacteria at different time-inter

5. 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

6. 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=

7. 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

8. 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

10. Disfunção cardíaca em animal nocaute para o receptor do tipo 2 para bradicinina
The Kinins are important peptides concerning control of cardiovascular function. Their action mechanism depend on the activation of two distinct receptor, type 1 and 2 bradykinin receptor (B1R and B2R). They both are coupled to G protein, which are responsible to activate different intracellular pathways, involved in different cellular process. Their role in

11. Análise estrutural e funcional da região promotora de rDNA de Leishmania (Viannia) braziliensis e estudo comparativo com as regiões de Leishmania (Leishmania) / Structural and functional caracterization of rDNA promoter region of Leishmania (Viannia) braziliensis and comparative study with the Leishmania (Leishmania) region
Leishmaniasis is the generic name of a serious public health problem that is caused by protozoa of the genus Leishmania. In its lifecycle, the parasite has two hosts, a vertebrate and an invertebrate. The genus Leishmania is divided into two subgenera: Leishmania (Leishmania) and Leishmania (Vianna), according to the position occupied by the promastigotes fo

12. Restauração de imagens de microscopia confocal utilizando técnicas POCS.
Computer Optical Sectioning Microscopy (COSM) is widely used in morphological studies of cellular structures. COSM appears as a great challenge to digital image processing, because the large size of the three-dimensional files. The major problem in COSM is the blurring, which practically turn the image unusable without the use of digital image processing tec
