2. Septic Pulmonary Embolism Requiring Critical Care: Clinicoradiological Spectrum, Causative Pathogens and Outcomes
OBJECTIVES: Septic pulmonary embolism is an uncommon but life-threatening disorder. However, data on patients with septic pulmonary embolism who require critical care have not been well reported. This study elucidated the clinicoradiological spectrum, causative pathogens and outcomes of septic pulmonary embolism in patients requiring critical care. METHODS

3. Effect of new innovative restorative carbomised glass cement on intrapulpal temperature rise: an ex-vivo study
Abstract This study aimed to evaluate the temperature changes that occurred in the pulp chamber when using GCP Glass Carbomer Fill (GCP) and two different resin-modified glass-ionomer (RGI) restorative materials at different dentin thicknesses. A standardized Class I occlusal cavity with 1 mm or 2 mm dentin thickness was prepared in the extracted human molar

4. Septic pulmonary embolism caused by a Klebsiella pneumoniae liver abscess: clinical characteristics, imaging findings, and clinical courses
OBJECTIVES: Septic pulmonary embolism caused by a Klebsiella (K.) pneumoniae liver abscess is rare but can cause considerable morbidity and mortality. However, clinical information regarding this condition is limited. This study was conducted to elucidate the full disease spectrum to improve its diagnosis and treatment. METHOD: We reviewed the clinical cha

5. Multidrug resistant tuberculosis versus non-tuberculous mycobacterial infections: a CT-scan challenge
INTRODUCTION: Clinical, laboratory and imaging findings in patients with multidrug resistanttuberculosis (MDR-TB) and non-tuberculosis mycobacterium (NTM) are similar, and the majority of these patients present with positive smear for Acid Fast Bacilli (ADB) and no response to first line anti-TB treatment, so sputum culture and PCR are necessary, especially

6. Análise de um amplificador klystron de múltiplas cavidades / Analysis of a klystron amplifier of multiple cavities
Neste trabalho investiga-se, inicialmente, o comportamento de um amplificador klystron de múltiplas cavidades segundo uma análise a pequenos sinais linear considerando o efeito de carga espacial para, na seqüência, apresentar uma análise do dispositivo utilizando um modelo não-linear a grandes sinais. Na primeira investigação apresenta-se, a partir d

8. A field-trial of two restorative materials used with atraumatic restorative treatment in rural Turkey: 24-month results
OBJECTIVE: The purpose of this study was to investigate the clinical performance of high-strength glass ionomer cement (HSGIC) and resin-modified glass ionomer (RMGIC) in single and multiple surface carious cavities in the field conditions. MATERIAL AND METHODS: A split-mouth design, including ninety-one fillings placed on contra lateral molar pairs of 37 ch

9. Properties and adhesion of glass ionomer cements modified by resin and bioactive glass-ceramic / Propriedades e adesão de cimentos de ionômero de vidro modificados por resina e vitrocerâmicas bioativas
Bioactive glass-ceramics are synthetic materials capable of chemically bonding to dental structures. Adhesion of resin-modified glass-ionomer cements (RMGICs) to dentin may be influenced by different types of dentin pre-treatments. The objective of this study was to analyze the compressive strength, roughness and adhesion to dentin of RMGICs (Fuji II LC and

10. Evolução de acarodomácias em Bignonieae (Bignoniaceae) / Evolution of acarodomatia in Bignonieae (Bignoniaceae)
Acarodomatia (or leaf domatia) are cavities or hair tufts found on the axils of veins on the abaxial surface of leaves. Several species of woody angiosperms mediate a mutualism with benefic mites (fungivorous and predaceous) through these structures. In this symbiotic relation, the leaf domatia provide refuge and protection to mites against natural enemies a

11. Influência dos níveis de energia do laser Er:YAG na capacidade de ablação, microdureza e morfologia da dentina superficial e profunda / Influence of Er:YAG laser energy levels on ablation rate, microhardness and morphology of superficial and deep dentin
This study evaluated the ablation rate and the subsurface microhardness of superficial and deep dentin irradiated with different Er:YAG laser energy levels, and observed the micromorphological aspects of the lased substrates by means of Scanning Electron Microscopy (SEM). Seventy-two molar crowns were bisected, providing 144 specimens, which were randomly as

12. EFEITO DO NAOCL A 10% E DA APLICAÇÃO DO COMPÓSITO DE BAIXA VISCOSIDADE SOBRE A RESISTÊNCIA DA UNIÃO COMPÓSITO-DENTINA / EFFECT OF NAOCL 10% AND THE APPLICATION OF LOW-VISCOSITY COMPOSITE ON RESIN/DENTIN BOND STRENGTH
The aim of this in vitro study was to evaluate the effect of NaOCl 10% as dentin superficial treatment and the application of a low-viscosity composite (LVC) on resin/dentin bond strength. Twenty human third molars, recently extracted, were divided in four experimental groups. The occlusal enamel was removed with a mechanical grinder perpendicular to the lon
