1. The use of a liner under different bulk-fill resin composites: 3D GAP formation analysis by x-ray microcomputed tomography
Abstract Gap formation of composite resin restorations is a serious shortcoming in clinical practice. Polymerization shrinkage stress exceeds the tooth-restoration bond strength, and it causes bacterial infiltration within gaps between cavity walls and the restorative material. Thus, an intermediate liner application with a low elastic modulus has been advis

2. Potencial antimicrobiano de diferentes retentores intrarradiculares frente a Enterococcus faecalis: uma avaliação in vitro
Resumo Introdução O tratamento endodôntico tem como objetivo erradicar microrganismos bacterianos e fúngicos do canal radicular, ou pelo menos possibilitar sua redução para níveis compatíveis com a saúde do tecido perirradicular, uma vez que, após o tratamento endodôntico, colônias de microrganismos residuais podem estar presentes nos túbulos d

3. Meglumine antimoniate intralesional infiltration for localised cutaneous leishmaniasis: a single arm, open label, phase II clinical trial
BACKGROUND Cutaneous leishmaniasis (CL) is a world-wide health problem which currently lacks effective, affordable and easy to use therapy. Recently, the meglumine antimoniate (MA) intralesional infiltration was included among the acceptable therapies for New World leishmaniasis. While this approach is attractive, there is currently little evidence to supp

4. Exogenous enzyme complex prevents intestinal soybean meal-induced enteritis in Mugil liza (Valenciennes, 1836) juvenile.
ABSTRACT Four soybean meal-based diets containing increasing levels of an enzyme complex (E50, E100, E150 and E200 at 50, 100, 150 and 200 g ton-1, respectively) and one soybean meal-based diet without the enzyme complex (E0) were fed in triplicate to M. liza juveniles in a semi-static flow system with 20 fish per tank for 75 days. There were no differences

5. Effect of glutamine supplementation on left colon healing in rats with extrahepatic biliary obstruction
PURPOSE:To evaluate the influence of glutamine and obstructive jaundice on left colon healing in rats.METHODS: Sixteen male rats were allocated across four groups: LG - Common bile duct ligation followed by colotomy and bowel suture on postoperative day 7. Supplementation with glutamine 2% from day 4 after duct ligation until euthanasia. L - Common bile duct

6. The multifaceted resources and microevolution of the successful human and animal pathogen methicillin-resistant Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most important bacterial pathogens based on its incidence and the severity of its associated infections. In addition, severe MRSA infections can occur in hospitalised patients or healthy individuals from the community. Studies have shown the infiltration of MRSA isolates of community origin int

7. Pathophysiology of bacterial infection of the central nervous system and its putative role in the pathogenesis of behavioral changes
Invasion of the central nervous system (CNS) by microorganisms is a severe and frequently fatal event during the course of many infectious diseases. It may lead to deafness, blindness, cerebral palsy, hydrocephalus, cognitive impairment or permanent neurological dysfunction in survivors. Pathogens can cross the blood-brain barrier by transcellular migration,

8. A influência da flora intestinal e da esplenectomia na resistência à insulina induzida por obesidade / Influence of gut microbiota and splenectomy over the obesity-induced insulin resistance
A high-fat diet intake induces obesity and chronic subclinical inflammation, which play important roles in insulin resistance. Increased circulating levels of proinflammatory cytokines, free fatty acids and lipopolysaccharides activate innate immune system, which triggers inflammation and cytokine expression, leading to insulin resistance. Thus, we investiga

9. Influência do alargamento foraminal na anatomia apical e na qualidade de selamento após obturação / Influence of apical foramen widening on apical foramen morphology and apical sealing
Introduction: The aim of this study was to evaluate the influence of the working length and apical foramen widening on the anatomy of the apical foramen and on the sealing ability after root canal filling. Methods: Fifty-five palatal roots of maxillary molars were selected. The samples were randomly divided into three groups (n=15) according to the different

10. Treatment of hemorrhagic shock with hypertonic saline solution modulates the inflammatory response to live bacteria in lungs
Shock and resuscitation render patients more susceptible to acute lung injury due to an exacerbated immune response to subsequent inflammatory stimuli. To study the role of innate immunity in this situation, we investigated acute lung injury in an experimental model of ischemia-reperfusion (I-R) followed by an early challenge with live bacteria. Conscious ra

11. In vitro comparative evaluation of MBPc, CPM, White Ângelus MTA cements and Lysanda paste®s sealing ability to bacterial infiltration in retrograde fillings / Avaliação comparativa "in vitro" da capacidade seladora do cimento MBPc, CPM, MTA Angelus® branco e pasta Lysanda® à infiltração bacteriana em obturações retrógradas
O objetivo deste estudo foi avaliar in vitro a capacidade seladora de alguns materiais odontológicos em retrobturações e para tanto, utilizou-se o MTA Ângelus® Branco, MBPc, CPM® e Pasta Lysanda®, através da análise da infiltração do Enterococcus faecalis. Noventa dentes humanos unirradiculares extraídos e instrumentados, tiveram seu ápice radic
