Evaluación de los indicadores de desempeño de 3M Petrifilm Staph Express (STX) frente a la norma ISO 6888-1: 2003 en el recuento de Staphylococcus aureus en quesos frescos por contaminación artificial

Con-ciencia (La Paz); 6 (1), 2018
Staphylococcus aureus puede contaminar una gran gama de alimentos, siendo los quesos frescos un medio diferencial y selectivo para el desarrollo de este microorganismo, llegando a la producción de enterotoxina termoestable ocasionando una intoxicación estafilocóccica trasmitida por alimentos. El emple...

Do We Need to Personalize Renal Function Assessment in the Stratification of Patients Undergoing Cardiac Surgery?

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Renal dysfunction is an independent predictor of morbidity and mortality in cardiac surgery. For a better assessment of renal function, calculation of creatinine clearance (CC) may be necessary. Objective: To objectively evaluate whether CC is a better risk predictor than serum cre...

Objetivo: Desarrollar y v...

Simultaneous Determination of Furan and Vinyl Acetate in Vapor Phase of Mainstream Cigarette Smoke by GC-MS

An. acad. bras. ciênc; 89 (1,supl), 2017
ABSTRACT A simple and sensitive method for simultaneous determination of furan and vinyl acetate (VA) in vapor phase of mainstream cigarette smoke with cold trap and gas chromatography-mass spectrometry (GC-MS) was developed. A Cambridge filter pad (CFP) was placed in front of the impingers of smoking ma...

Biological X-ray irradiator characterization for use with small animals and cells

Braz. j. med. biol. res; 50 (3), 2017
This study presents the characterization of an X-ray irradiator through dosimetric tests, which confirms the actual dose rate that small animals and cells will be exposed to during radiobiological experiments. We evaluated the linearity, consistency, repeatability, and dose distribution in the positions ...

Digital orthodontic radiographic set versus cone-beam computed tomography: an evaluation of the effective dose

ABSTRACT Objective: The aim of this study was to compare the equivalent and effective doses of different digital radiographic methods (panoramic, lateral cephalometric and periapical) with cone-beam computed tomography (CBCT). Methods: Precalibrated thermoluminescent dosimeters were placed at 24 locat...

Calibration of the maximum carboxylation velocity (Vcmax) using data mining techniques and ecophysiological data from the Brazilian semiarid region, for use in Dynamic Global Vegetation Models

Braz. j. biol; 76 (2), 2016
Abstract The semiarid region of northeastern Brazil, the Caatinga, is extremely important due to its biodiversity and endemism. Measurements of plant physiology are crucial to the calibration of Dynamic Global Vegetation Models (DGVMs) that are currently used to simulate the responses of vegetation in fa...
