1. Influence of Cavity Dimensions on Microleakage of Two Bulk-Fill Composite Resins
Abstract Objective: To evaluate the effect of cavity dimensions on the amount of microleakage in two different types of bulk-fill composite resins. Material and Methods: Forty class II cavities were prepared in the mesial and distal surfaces of human molars without any carious lesions. The samples were divided into 4 groups (n=10): Group 1: cavities with 3

3. Lesions in 224 spleens of splenectomized dogs and evalution of alternative techniques for previous microscopic diagnosis
RESUMO: Rotineiramente, frente à detecção de uma lesão proliferativa esplênica, médicos veterinários costumam optar pela esplenectomia antes de se obter o diagnóstico definitivo da lesão esplênica, o que pode trazer consequências deletérias ao cão. O mais apropriado seria, contudo, a sua adoção, como medida terapêutica, apenas nos casos com c

6. Internal configuration of maxillary molars in a subpopulation of Brazil’s Northeast region: A CBCT analysis
Abstract The present study aimed to evaluate the internal configuration of the maxillary molars of a population from the Northeast region of Brazil. Cone-beam computed tomography (CBCT) exams from 512 patients (1501 teeth) were evaluated regarding the anatomical configuration of the root canal system, according to Vertucci’s classification. The images were

8. Vibration analysis of laminated functionally graded shallow shells with clamped cutout of the complex form by the Ritz method and the R-functions theory
Abstract The R-functions theory and Ritz approach are applied for analysis of free vibrations of laminated functionally graded shallow shells with different types of curvatures and complex planforms. Shallow shells are considered as sandwich shells of different types: a) face sheets of the shallow shells are made of a functionally graded material (FGM) and t

9. Detection of sputum cofilin-1 as indicator of malignancy
Cofilin-1 (CFL1), a small protein of 18 kDa, has been studied as a biomarker due to its involvement in tumor cell migration and invasion. Our aim was to evaluate CFL1 as an indicator of malignancy and aggressiveness in sputum samples. CFL1 was analyzed by ELISA immunoassay in the sputum of 73 lung cancer patients, 13 cancer-free patients, and 6 healthy volun

11. Soil Biodegradation of PLA/CNW Nanocomposites Modified with Ethylene Oxide Derivatives
Due to its ester bonds, poly(lactic acid) (PLA) undergoes biodegradation in humid environments, attracting market attention. The goal of this work was to observe the biodegradation in garden soil of PLA nanocomposites with neat (PLA/CNW) and surfactant modified cellulose nanowhiskers (PLA/CNW/S). Three types of surfactants were tested: poly(ethylene glycol)
