    Shiga Toxin Detection Methods : A Short Review

    Full text link
    The Shiga toxins comprise a family of related protein toxins secreted by certain types of bacteria. Shigella dysenteriae, some strain of Escherichia coli and other bacterias can express toxins which caused serious complication during the infection. Shiga toxin and the closely related Shiga-like toxins represent a group of very similar cytotoxins that may play an important role in diarrheal disease and hemolytic-uremic syndrome. The outbreaks caused by this toxin raised serious public health crisis and caused economic losses. These toxins have the same biologic activities and according to recent studies also share the same binding receptor, globotriosyl ceramide (Gb3). Rapid detection of food contamination is therefore relevant for the containment of food-borne pathogens. The conventional methods to detect pathogens, such as microbiological and biochemical identification are time-consuming and laborious. The immunological or nucleic acid-based techniques require extensive sample preparation and are not amenable to miniaturization for on-site detection. In the present are necessary of techniques of rapid identification, simple and sensitive which can be employed in the countryside with minimally-sophisticated instrumentation. Biosensors have shown tremendous promise to overcome these limitations and are being aggressively studied to provide rapid, reliable and sensitive detection platforms for such applications.Comment: 16 pages, 2 figure

    The first order equation relating object and image location for a mirror of arbitrary conic-sectional shape is derived. It is also shown that the parabolic reflecting surface is the only one free of aberration and only in the limiting case of distant sources.Comment: 9 page

    ¿Qué es una carretera inteligente?

    A smart road is the planning of avenues or roads that become advanced intelligent platforms, which allow detailed infrastructure to embody or develop their functions (such as traffic signals and tolls). It allows vehicles to communicate and share an essential information base with deterministic characteristics between a system for receiving and exporting information. In this way, a driver can know in advance if a traffic accident has occurred or if weather conditions are making it difficult for vehicles to pass. This article documents several characteristic aspects of the functioning of each of the parts that make up the intelligent highway.Una carretera inteligente consiste en la planeación de avenidas o caminos que se conviertan en avanzadas plataformas inteligentes, que permiten que la detallada infraestructura plasme o desarrolle sus funciones (como señales de tránsito y peajes). Permite que los vehículos se comuniquen y compartan una base información esencial con características determinantes a los factores, entre un sistema de recepción y exportación de información. De esta manera, un conductor puede conocer con anticipación si se registró un accidente de tránsito o si las condiciones climáticas están dificultando el paso de vehículos. Este articulo documenta varios aspectos característicos del funcionamiento de cada una de las partes que componen a la carretera inteligentes
