13. POLYETHERIMIDE/POLYVINYLPYRROLIDONE HOLLOW-FIBER MEMBRANES FOR USE IN HEMODIALYSIS
Abstract In this study, polyetherimide/polyvinylpyrrolidone (PEI/PVP) hollow fiber membranes (HFMs) were synthesized by the phase inversion method. The synthesized PEI/PVP membranes were characterized by morphological analysis and transport properties (hydraulic permeability and solute rejection coefficient). Their performance in uremic solutes separation wa

14. Effect of passive ultrasonic activation on microorganisms in primary root canal infection: a randomized clinical trial
Abstract Objective: This clinical study sought to evaluate the effectiveness of passive ultrasonic activation (PUA) in eliminating microorganisms in primary endodontic infection (PEI) after instrumentation of root canals using microbiological culture and checkerboard DNA-DNA hybridization. Methodology: Twenty root canals with PEI and apical periodontitis w

15. Cardioprotection of Rosuvastatin Pre-conditioning on Myocardial Ischemia / Reperfusion Injury in a Rat Model
Abstract This study aimed to investigate the cardioprotection of rosuvastatin pre-conditioning (R-Pre) in a rat model of myocardial ischemia / reperfusion (I/R). Male SD rats were assigned into three groups: sham group, I/R group and R-Pre group. Rats in I/R group and R-Pre group received ischemia for 30 min and reperfusion for 2 h. In R-Pre group, rats rec

16. Role of low dose 256-slice CT perfusion imaging in predicting mediastinal lymph node metastasis of lung cancer
RESUMO OBJETIVOS: A perfusão por TC objetiva (CTP) é uma técnica de imagem que pode ser usada para avaliar as alterações na microcirculação de tecidos tumorais. Nosso estudo teve como objetivo investigar o papel da CTP na predição de metástases em linfonodos mediastinais. MÉTODOS: Dados clínicos de 58 pacientes que receberam ressecção cirúrg

17. PERTINENCE CURVES IN FUZZY MODELING OF THE PRODUCTIVE RESPONSES OF BROILERS
ABSTRACT The selection of the type of fuzzy systems pertinence curve allows a better representation of the mathematical model and a smaller simulation error. We aimed to study the effect of pertinence curves in fuzzy modeling of broiler performance, created in different production systems. For the development and testing of fuzzy models, three commercial avi

18. Correlation Between Volume of Root Canal, Cultivable Bacteria, Bacterial Complexes and Endotoxins in Primary Infection
Resumo Este estudo clínico foi conduzido para correlacionar os níveis de endotoxinas e bactérias cultiváveis encontradas na infecção endodôntica primária (IEP) com o volume do canal radicular determinado pelo uso da Tomografia Computadorizada de Feixe Cônico (TCFC); e avaliar a diversidade bacteriana correlacionada com características clínicas.

19. PRODUCTIVE RESPONSES FROM BROILER CHICKENS RAISED IN DIFFERENT COMMERCIAL PRODUCTION SYSTEMS - PART I: FUZZY MODELING
ABSTRACT Broiler chickens are classified as homoeothermic animals and require a production environment within well-defined thermal comfort intervals. Therefore, the development of algorithms (mathematical models) to control the environment that can be embedded in microcontrollers becomes necessary. Hence, this work aimed to develop a fuzzy model for predicti

20. Inclusão escolar e o planejamento educacional individualizado: estudo comparativo sobre práticas de planejamento em diferentes países
RESUMO Traça-se um panorama histórico acerca do conceito de plano educacional individualizado - PEI, apontando as consequentes mudanças nas práticas nele estabelecidas em decorrência da segregação e da inclusão escolar. Apresenta-se análise da legislação sobre PEI e dos modelos de execução desse tipo de planejamento em países, a saber: França,

22. Synthesis, Characterization, and Photocatalytic Properties of Flower-like Mn-doped Ceria
Mn-doped CeO2 flower-like microstructures have been synthesized by a facile one-step composite-hydroxide-mediated method. The structure, morphology, optical and the surface properties of Mn doped CeO2 have been investigated by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), UV-Vis absorption spectroscopy and X-ray photoelectron

23. Performance of probe polymerization-conjunction-agarose gel electrophoresis in the rapid detection of KRAS gene mutation
Abstract This study aimed to develop a simple and rapid method to detect KRAS gene mutations for conventional clinical applications under laboratory conditions. The genotype of mutation sites was determined based on the occurrence of target bands in the corresponding lanes of the reaction tubes through polymerization-conjunction of the probes, probe purifica

24. Cytidine-phosphate-guanosine oligodeoxynucleotides in combination with CD40 ligand decrease periodontal inflammation and alveolar bone loss in a TLR9-independent manner
Abstract Local administration of toll-like receptor 9 (TLR9), agonist cytidine-phosphate-guanosine oligodeoxynucleotide (CpG ODNs), and CD40 ligand (CD40L) can decrease ligature-induced periodontal inflammation and bone loss in wild type (WT) mouse. Objective: This study aimed to explore whether such effect is dependent on TLR9 signaling. Material and Meth
