Resumen en español Las técnicas experimentales de microrreología óptica y reología clásica han sido aplicadas para estudiar las propiedades viscoelásticas de un copolímero asociativo (PA) de tipo multiunión en disolución acuosa en el régimen semidiluido no entrelazado. Este copolímero está constituido de acrilamida en mayor proporción (99 % mol) y una pequeña cantidad de un monómero hidrófobo N,N-dioctilacrilamida (DOAM) (<1 % mol). Bajo ciertas condiciones fisicoquímica (mas) s los PA se autoasocian en agregados de tamaño nanométrico formando microgeles físicos temporales con propiedades viscoelásticas. La técnica de microrreología pasiva utiliza la dispersión dinámica de luz (DLS) para obtener información de las propiedades dinámicas locales del PA en solución acuosa, por medio de la difusión de traslación de partículas trazadoras inmersas en el fluido complejo. Con esta técnica experimental el rango de frecuencias es extendido hasta 50,000 s-1, permitiendo obtener mayor información de los módulos viscoelásticos G'() y G"(). En este trabajo se presenta un estudio de las propiedades viscoelásticas en función de la concentración y tamaño de la partícula trazadora, y también de la concentración del PA. El comportamiento viscoelástico del PA en solución acuosa ha sido interpretado utilizando el modelo de Rubinstein y Semenov [1]. Resumen en inglés The experimental techniques of optical microrheology and classical rheology have been applied to study the viscoelastic properties of aqueous solution of an associative copolymer (AP) multisticker in the unentangled semidiluted regimen of concentration. Polymer chains consists of polyacrylamides (99 %mol), hydrophobically modified with low amounts (<1 % mol) of N,N-dioctylacrylamide (DOAM). Under certain physicochemical conditions these AP self assemble in aggregates o (mas) f nanometric size to form physical transitory microgeles, resulting in viscoelastic fluids. The passive microrheological technique uses dynamic light scattering to obtain the information of the local dynamic properties of aqueous solutions of associating polymers. With these experimental techniques the range of frequencies is extended up to 50,000 s-1, allowing to obtain more information of the moduli G'() y G"(). In this work, a study of the concentration and diameter of tracer particles also the concentration of AP on the viscoelastic properties has been performed. The viscoelastic behavior of aqueous solutions of AP has been interpreted using the theoretical model of Rubinstein and Semenov [1].

Asociación molecular y función del agente tensioactivo pulmonar de ternera/ Molecular association and function of calf lung surfactant

Martínez Montaño, María del Lurdez Consuelo; Muñoz Sánchez, José Luis; Baeza Ramírez, Isabel
2007-06-01

Resumen en español El agente tensioactivo pulmonar es un material compuesto de fosfolípidos, lípidos neutros y proteínas que se encuentra en la superficie alveolar de los pulmones y facilita la ventilación alveolar. La organización molecular de los componentes del agente tensioactivo aislado de pulmones de ternera fue analizada por calorimetría diferencial de barrido y por dispersión dinámica de luz y posteriormente comparada con los componentes organizados en liposomas uni y multil (mas) amelares; además, se probó la actividad de superficie al desarrollar en cobayos el síndrome de dificultad respiratoria. Los estudios de calorimetría mostraron que las interacciones lípido-proteína fueron considerablemente abatidas en el agente tensioactivo nativo, en comparación con las del agente tensioactivo en forma de liposomas uni o multilamelares. Los experimentos de dispersión dinámica de luz indicaron que el agente tensioactivo nativo tiene forma fibrilar con interacciones limitadas entre lípidos y proteínas, lo que sugiere que se encuentra organizado en una estructura en forma de reja formando una película de estructura estable. Los resultados obtenidos resaltan la importancia de la organización molecular del agente tensioactivo. Cuando éste fue usado para tratar a los animales con síndrome de dificultad respiratoria, los valores del pH arterial y de PaCO2 mejoraron casi hasta alcanzar los valores normales; cuando se utilizó el agente tensioactivo reconstituído como liposomas uni o multilamelares, los animales no se recuperaron. Es importante enfatizar que el método seguido en el protocolo de aislamiento del agente tensioactivo pulmonar de ternera permitió obtenerlo en una forma fisiológicamente activa. Resumen en inglés Surfactant, a highly surface-active material composed of phospholipids, neutral lipids and proteins, lines the lungs' alveolar surface facilitating alveolar ventilation. The molecular organization of surfactant components isolated from calf-lungs was analyzed by differential-scanning calorimetry and dynamic light-scattering, and subsequently compared to surfactant components organized in uni and multilamellar liposomes. The respiratory distress syndrome developed in adult (mas) guinea pigs was used for assessing surfactant activity. Calorimetry studies showed that lipid-protein interactions were considerably abated in native surfactant as compared to those of surfactant in uni or multi-lamellar liposomes. Light-scattering experiments indicated that native surfactant has a fibrillar shape with limited lipid-protein interactions, suggesting that it is organized in a lattice-like structure forming a stable film. These findings underscore the importance of the native molecular organization of surfactant. When surfactant reconstituted as uni- or multilamellar liposomes was administred to animals under respiratory distress, they did not recover. In contrast, when native surfactant was used to treat sick animals, arterial pH and PaCO2 values improved, almost reaching normal values. It is important to emphasize that fewer steps in the protocol for isolation of calf lung surfactant made it possible to obtain it in a physiologically active molecular form.

Método de difusión lumínica aplicado a la capacidad inhibitoria para epitopes ABO en Ascaris lumbricoides/ Light Diffraction of suspended particles Method (Light Scattering) applicable to Inhibitory Capacity in relation to ABO epithopes in Ascaris lumbricoides

Ponce de León, Patricia; Foresto, Patricia; Valverde, Juana
2005-12-01

Resumen en español Experiencias previas demostraron la presencia de epitopes ABO en Ascaris lumbricoides. El objetivo de este trabajo fue determinar la capacidad inhibitoria del parásito para estos epitopes por cuantificación de la hemaglutinación aplicando el método de difusión lumínica por partículas en suspensión. Se seleccionaron 8 extractos parasitarios (EA) de pacientes grupo sanguíneo B y 4 de grupo A (con y sin epitopes ABO). Los EA fueron enfrentados a diluciones de antisu (mas) ero monoclonal (anti A o anti B) y el antisuero excedente fue neutralizado con eritrocitos de isogrupo. Se midió la extinción óptica de la aglutinación resultante. Se graficó el porcentaje de aglutinación en función de la dilución del antisuero para calcular Título-50 (T-50). Se definió Poder Inhibitorio (PI) como la relación entre el T-50 del EA estudiado y el T-50 de un EA control. Se determinó la concentración proteica del extracto para expresar PI/ gramo de proteína. Los valores de PI para los EA con epitopes ABO fueron mayores a 1. El cociente PI/ gramo de proteína permitió obtener valores representativos de la cantidad de epitopes presentes. La utilización de este método corroboró la presencia de epitopes ABO en los extractos y comparó la capacidad inhibitoria de diferentes extractos para estos epitopes. Resumen en inglés Previous experiences have shown ABO epithopes presence in Ascaris lumbricoides. The aim of this work was to determine the inhibitory capacity of A. lumbricoides in relation to ABO epithopes by light diffraction of suspended particles method (Light Scattering). Eight parasite extracts (AE) from B Group patients and 4 AE from A Group patients (AE with and without ABO epithopes) were selected. The AE were faced against dilutions of monoclonal antibody (anti A or anti B). The (mas) exceeding antibody was neutralized with isogroup erythrocytes. The optical extinction of the agglutinates was measured. The agglutination percentage versus antibody dilution was graficated. Titre-50 (T-50) was calculated. Inhibitory Power (IP) was defined as the relation between T-50 of the studied extract and T-50 of the control extract The protein concentration of the AE was determined to express IP/ protein gram. IP values for the AE with ABO epithopes were greater than 1. The IP/ protein gram made it possible to obtain representative values of the ABO epithopes amount in each extract l. The utilization of this method enabled corroboration of the ABO epithopes presence and comparison of the inhibitory capacity for these epithopes between different extracts.
