1. Laryngopharyngeal Reflux: Symptoms, Signs, and Presence of Pepsin in Saliva - A Reliable Diagnostic Triad
Abstract Introduction Twenty-four-hour multichannel intraluminal impedance with double probe pH monitoring (MII-pH), though considered the most sensitive tool for the diagnosis of gastroesophageal reflux disease (GERD), is invasive, time consuming, not widely available, and unable to detect non-acid reflux. In contrast, the presence of pepsin in the saliva

2. Serum regucalcin is a useful indicator of liver injury severity in patients with hepatitis B virus-related liver diseases
Regucalcin is a soluble protein that is principally expressed in hepatocytes. Studies of regucalcin have mainly been conducted in animals due to a lack of commercially available kits. We aimed to develop an enzyme-linked immunosorbent assay (ELISA) to quantify serum regucalcin in patients with hepatitis B virus (HBV)-related disease. High-titer monoclonal an

3. Implantação de stent autoexpansível para tratamento de estenose uretral em cão: relato de caso
RESUMO O stent endovascular autoexpansível pode ser utilizado como forma de tratamento para estenose uretral em cães. O stent de nitinol é composto por uma liga de níquel e titânio que permite mudanças em suas estruturas sob a influência da temperatura corporal e tem excelente biocompatibilidade na uretra canina. Este estudo relata o caso de um cão,

4. Immunogenicity and safety of the combined vaccine for measles, mumps, and rubella isolated or combined with the varicella component administered at 3-month intervals: randomised study
BACKGROUND Field testing required to license the combined measles, mumps, and rubella (MMR) vaccine must take into account the current recommendation of the vaccine in Brazil: first dose at 12 months and second dose at 15 months of age in combination with a varicella vaccine. OBJECTIVES This study aimed to evaluate the clinical consistency, immunogenicit

5. Free vibration analysis of nano-tubes consisted of functionally graded bi-semi-tubes by a two-steps perturbation method
Abstract Free vibration of a bimaterial circular nano-tube is investigated. The tube is formed by bonding together a Si3N4/SUS304 functionally graded upper semi tube and a ZrO2/Ti-6Al-4V functionally graded lower semi tube. The material properties of the tube are assumed to vary along the radius according to power law with the power index of upper semi tube

6. Numerical Studies of Penetration in Light Armor, Concrete and Brick-Wall Targets
ABSTRACT The accurate numerical simulation of projectile penetration process is a complex challenge. Experimental investigation of these time-dependent non-linear events is expensive and time-consuming. In this paper, 3-D numerical simulations are carried out to estimate the penetration performance of designed penetrators against the double and triple brick-

7. MANEJO DE RESIDUOS DE Eucalyptus grandis Hill ex Maiden EN SITIOS CONTRASTANTES
ABSTRACT In northeastern Argentina, very little is known about the impact of various techniques of management of residues from forest harvesting on soil properties. We carried out this study in two sites in Entre Ríos Province (Argentina): post-harvest of Eucalyptus grandis Hill ex Maiden stands in an Aquic Hapludert (S1) and in a Fluventic Hapludoll (S2).

8. Intraparenchymal hematoma as a late complication of retrograde intrarenal surgery
ABSTRACT A 34 year-old woman was admitted to our hospital with left flank pain. A non-contrast enhanced computerized tomography (NCCT) revealed a 1.5x2cm left proximal ureter stone. Patient was scheduled for ureterorenoscopy (URS) and stone removal. She was submitted to retrograde intrarenal surgery (RIRS). At the postoperative 1st day, the patient began to

9. Analysis of labour risks in the Spanish industrial aerospace sector
ABSTRACT Labour risk prevention is an activity integrated within Safety and Hygiene at Work in Spain. In 2003, the Electronic Declaration for Accidents at Work, Delt@ (DELTA) was introduced. The industrial aerospace sector is subject to various risks. Our objective is to analyse the Spanish Industrial Aerospace Sector (SIAS) using the ACSOM methodology to as

10. Multidrug resistance and ESBL-producing Salmonella spp. isolated from broiler processing plants
Abstract The aim of this study was to investigate the occurrence of multidrug-resistant, extended spectrum beta-lactamase (ESBL) producing Salmonella spp. isolated from conveyor belts of broiler cutting rooms in Brazilian broiler processing plants. Ninety-eight strains of Salmonella spp. were analyzed. Multidrug resistance was determined by the disk diffusio

11. Assessment of hospital daily cleaning practices using ATP bioluminescence in a developing country
Visual assessment of surfaces may not be enough to document the level of cleanliness in the hospital setting. It is necessary to introduce quantitative methods to document the results of this practice.Objective:To evaluate the efficacy of hospital terminal cleaning procedures, using an adenosine triphosphate (ATP) bioluminescence method in a teaching hospita

12. Discrepancies in degree of conversion measurements by FTIR
The purpose of this study was to evaluate the influence of the internal standard peak on the measured degree of conversion (DC) for methacrylate-based resins analyzed by Fourier-transform infrared spectroscopy (FTIR). The influence of different baseline measurement methods was also determined. Different blends were prepared, mixing BisGMA/BisEMA and BisGMA/T
