Introducción: La administración de surfactante pulmonar tradicionalmente se realiza mediante un tubo endotraqueal, pero desde hace años existen técnicas menos invasivas como la administración mediante másscara laríngea, aerosolización y cateterización traqueal. Objetivos: Demostrar la evolución...
Copaifera spp. essential oil (EOC) was extracted by hydrodistillation of Copaifera oleoresin (COR). The EOC was characterized by GC/MS and a novel EOC-loaded nanoemulsion was developed to enhance the EOC solubility and to evaluate its utility as antinflammatory. EOC contain 14 volatile compounds (includ...

Abstract The objective of this study was to determine the influence of nonionic surfactants on the effectiveness of preservatives used in emulsions containing high surfactant content. Mixtures of different concentrations were prepared between polyethoxylated (40) hydrogenated castor oil (PHCO) and polyox...
Resumen Introducción: Los trastornos genéticos que afectan la homeostasis del surfactante pulmonar son una causa importante del síndrome de dificultad respiratoria en el recién nacido a término y de enfermedad pulmonar intersticial difusa en niños. El transportador ABCA3 (ATP binding cassette A3) ...

Science has greatly contributed to the advancement of technology and to the innovation of production processes and their applications. Cleaning products have become indispensable in today’s world, as personal and environmental hygiene is important to all societies worldwide. Such products are used in t...
Abstract Synthetic dyes, particularly reactive and acid dyes, are commonly used in the textile industry because of their advantages as excellent color fastness and brightness. Also, surfactants are used for an increment of coloring success in the textile industry. One of the major problems concerning tex...
BACKGROUND: The present study describes the production of biosurfactant (BS) and emulsifier (BE) by the filamentous fungus Mucor hiemalis UCP 0039, as well as the characterization and stability of the both biomolecules for environmental or industrial applications. RESULTS: Biosurfactants and bioemulsifie...
BACKGROUND: Biosurfactants are biomolecules that have the potential to be applied in food formulations due to their low toxicity and ability to improve sensory parameters. Considering the ability of yeasts to produce biosurfactants with food-friendly properties, the aim of the present study was to apply ...
ABSTRACT Objective: To analyze the accuracy of the Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE II) as a death predictor, to determine the cutoff point for mortality, and to analyze the association of independent variables with death. Methods: Prospective, longitudinal, hospital-base...
