    "Existe una prueba clínica diagnóstica para pacientes con sospecha de síncope vasovagal (SVV), disautonomía y taquicardia postural paroxística, la cual nos ayuda a la correcta clasificación y orientación del diagnóstico. La Prueba de inclinación (PI), es un examen que consta de dos fases, una pasiva y una activa, en la fase pasiva el paciente se cambia de posición supina a posteriormente inclinado (75°); en la fase activa se hace lo mismo y se agrega un medicamento vasodilatador, se analizan las constantes vitales, frecuencia cardiaca, presión arterial y saturación de oxígeno. Con base en el comportamiento y la variación de estas constantes junto con la respuesta clínica, se ubica al paciente en el grupo que le corresponde (respuesta clínica y respuesta hemodinámica) y se inicia tratamiento. En el instituto nacional de cardiología Ignacio Chávez, al ser un centro de referencia nacional con alta demanda de pacientes, el departamento de Electrocardiología decidió acortar su protocolo de la prueba de inclinación para los pacientes con sospecha de síncope, disminuyendo el tiempo total de la prueba y aumentando el número de pruebas de inclinación al día para así poder cubrir las necesidades del servicio"

    Plantear un modelo de administración y gestión de la red de área local del Edificio Central de la Universidad Técnica del Norte, a través de la implementación de una herramienta de gestión, en base al modelo de gestión OSI con el protocolo SNMP, para mejorar el rendimiento de la red.La administración de redes es un conjunto de técnicas tendientes a mantener una red operativa, eficiente, segura, constantemente monitoreada y con una planeación adecuada y debidamente documentada. Tiene como objetivo mejorar la continuidad en la operación de la red con mecanismos adecuados de control y monitoreo, así como hacer uso eficiente de la red y utilizar mejor los recursos de la misma. Hoy en día las instituciones públicas dependen más que nunca de su infraestructura informática. La disponibilidad constante, sin interrupciones, y el rendimiento óptimo de la red, se han convertido en factores fundamentales ya que el más pequeño problema con la red puede tener efectos negativos. La red interna del Edificio Central de la Universidad Técnica del Norte, al tener una gran cantidad de usuarios es una red que está sujeta a cambios e inconvenientes frecuentes. La complejidad de la red hace que la tarea de mantener el correcto funcionamiento de la misma sea difícil. Al suscitarse un problema en alguno de los componentes de la red, éste no se notifica de manera automáticamente, además es necesario que el administrador de red y su equipo de trabajo verifiquen personalmente el funcionamiento de los equipos para encontrar la falla. Otro inconveniente es que al no tener registros que acerca de los eventos que se producen en la red no se pueden aplicar medidas preventivas. Se implementa un modelo de gestión de red en el Edificio Central de la Universidad Técnica del Norte en base a las áreas funcionales que contempla el modelo de gestión de red ISO/OSI, siendo éstas: Gestión de configuraciones, gestión de fallos, gestión de contabilidad, gestión de prestaciones y gestión de seguridad. Mediante la implementación de software de distribución libre se consigue un sistema de gestión de red que cubre las cinco áreas funcionales mencionadas, brindando una red continuamente monitoreada, en donde los problemas que se pueden suscitar son detectados a brevedad. Se establecen políticas y manuales de procedimientos en concordancia con las cinco áreas funcionales que propone el modelo de gestión de red ISO/OSI, para que sirvan como guía para la adecuada utilización del sistema de gestión de red y sus componentes

    Desde tiempos ancestrales el hombre ha hecho uso de la medición como herramienta para su desarrollo y evolución. El objetivo de esta publicación es realizar el análisis y evaluación del impacto de la metrología en el sistema de salud colombiano. Para ello se establecen inicialmente los conceptos y definiciones sobre la metrología, sus principales componentes y su historia. Enseguida se identifican cuáles son los organismos que rigen los procesos metrológicos a nivel mundial y se describe su función, los criterios de aceptación y los requisitos para la aplicación y ejecución de los procedimientos de medición tanto a nivel mundial como en Colombia. Sin embargo, a pesar de la existencia de dichos criterios y requisitos para la aplicabilidad de la metrología, el cocimiento del operador de los instrumentos de medición sobre estas normas permanece reducido. Es por ello que la supervisión de los mismos se ha convertido en un requisito claro. Actualmente la organización Internacional de Normalización ISO y La Comisión Electrotécnica Internacional IEC, forman el sistema especializado para la normalización mundial y son los encargados de formular las diferentes normas. En este documento analizaremos la norma ISO/IEC17025 de 2005 en la cual se establecen de manera clara los requisitos y requerimientos generales para la competencia de los laboratorios de ensayo y de calibración. La Norma ISO/IEC 17025 ha sido preparada por los comités de dichos organismos para la evaluación de la conformidad CASCO.1 Luego de establecer cuáles son los principales componentes y criterios de la metrología, de identificar los diferentes organismos que regulan las actividades en dicha área y la normatividad actual que rige este aspecto, se analizara la situación actual de la misma en nuestro país y posteriormente se observara la relación existente entre la metrología y el sistema de salud nacional. Finalmente se realiza la identificación de las consecuencias actuales y futuras de la metrología y el impacto en el sistema de salud nacional y se presentarán los resultados obtenidos. Adicionalmente se dejan las recomendaciones para el trabajo futuro y las respectivas referencias.RESUMEN INTRODUCCION 1. PLANTEAMIENTO DEL PROBLEMA 1.1 Criterios 1.2 Formulación del problema 2.

    Study of the Antihypertensive Peptides Derived from Alpha-Lactalbumin Hydrolysate after Simulation of Digestion

    Get PDF
    Alpha-lactalbumin is a whey protein that is a cheese-making industrial residue of high biological value. The antihypertensive capacity of three peptides obtained from the simulated gastrointestinal digestion of alpha-lactalbumin hydrolysates was studied. The alpha-lactalbumin hydrolysis was performed using the Alcalase enzyme and was subsequently subjected to a simulated digestion process using pepsin and pancreatin enzymes to mimic digestion conditions. The peptides were identified from a RP-HPLC fractionation of the digest and subsequent identification by mass spectrometry analysis. Three peptides from the alpha-lactalbumin sequence were obtained: IWCKDDQNPH (P1), KFLDDDLTDDIM (P2), and DKFLDDDLTDDIM (P3). The in vitro antihypertensive activity of the peptides was determined by studying the inhibition of the angiotensin-converting enzyme, with P1 being the only peptide with antihypertensive activity detected by this methodology (IC₅₀ = 3.91 ± 0.2 mg/mL). In order to correlate the structural (molecular dynamics simulations) and physicochemical properties with potential mechanisms of antihypertensive capacity, in silico methods were performed. The peptides P1, P2, and P3 had a negative global charge and were hydrophilic. After molecular modeling, the peptide structures were submitted to a refinement based on an energy minimization and further molecular dynamics simulation to assess their global size and conformational space. After a 50-nanosecond simulation, the global structures, solvated and immersed in an ionic water solution similar to that of blood, were studied in their solvent-accessible surfaces. A secondary structure (alpha-helix) was observed in the P1 peptide, but in general, all peptides showed an extended folding. The surfaces were charge code colored and in a visual inspection it could be conjectured that all of them exposed the charge, mainly a negative charge, to the solvent surface, in agreement with the GRAVY index, which was also evaluated. In conclusion, the structure and amino acid composition of peptide 1 assessed by in silico studies agrees with the antihypertensive activity obtained by the in vitro study.Centro de Investigación y Desarrollo en Criotecnología de Alimento

    Preliminary in vivo characterization of a theranostic aptamer: Sgc8-c- DOTA-67Ga

    Get PDF
    Nucleic acid aptamers can recognise their target with high affinity and specificity, and their potential as molecular imaging agents and use in theranostics are being explored. Compared with antibodies, aptamers can be easily synthesized and chemically modified, rendering them a valuable tool for in vivo approaches. Herein, we investigated a 41nt DNA aptamer as a theranostic agent for lymphoma and melanoma. This aptamer exhibits specific binding and high affinity for the PTK7 receptor that is overexpressed in many cancer cells. A 5’-amino-derivative of the Sgc8-c aptamer was bound to the metal chelator DOTA (1,4,7,10-tetraazacyclododecane- 1,4,7,10-tetraacetic acid) and labelled with the radionuclide 67Ga, forming the aptamer probe Sgc8- c-DOTA-67Ga. Different conditions during synthesis, purification and identification of the intermediate and final radiolabelled probe, were examined. Aptamer modification and radiolabelling were performed with high yields, resulting in a probe that was stable in neutral buffered solution. Binding to PTK7 was studied in CCRFCEM, A20 and B16F1 cell lines, and in purified PTK7-1 receptor, to confirm specificity. The in vitro cell lines showed different levels of uptake, and the signal increased over time. In vivo binding properties were studied in A20 and B16F10 tumour-bearing mice and images were acquired using X-rays and gamma imaging modalities for both models. Preliminary results in both tumour models showed good aptamer uptake by tumour. Hepatobiliar metabolism was observed with Sgc8-c-DOTA-67Ga and no signal was detected in normal tissue. In summary, these results support the utility of labelled aptamers as theranostic agents in different imaging modalities and theranostic

    Growth of pineapple plantlets during acclimatisation can be monitored through automated image analysis of the canopy

    Full text link
    [EN] Pineapple is an economically important tropical fruit crop, but the lack of adequate planting material limits its productivity. A range of micropropagation protocols has been developed over the years to address this shortfall. Still, the final stage of micropropagation, i.e. acclimatisation, remains a challenge as pineapple plantlets grow very slowly. Several studies have been conducted focusing on this phase and attempting to improve plantlet growth and establishment, which requires tools for the non-destructive evaluation of growth during acclimatisation. This report describes the use of semi-automated and automated image analysis to quantify canopy growth of pineapple plantlets, during five months of acclimatisation. The canopy area progressively increased during acclimatisation, particularly after 90 days. Regression analyses were performed to determine the relationships between the automated image analysis and morphological indicators of growth. The mathematical relationships between estimations of the canopy area and the fresh and dry weights of intact plantlets, middle-aged leaves (D leaves) and roots showed determination coefficients (R2) between 0.84 and 0.92. We propose an appropriate tool for the simple, objective and non-destructive evaluation of pineapple plantlets growth, which can be generally applied for plant phenotyping, to reduce costs and develop streamlined pipelines for the assessment of plant growthThis research was not covered by any specific grant but supported by internal funds from the Bioplant Centre (Cuba), the Agricultural Research Council-Tropical and Subtropical Crops (South Africa), and the Universitat Politecnica de Valencia (Spain).

    Tannat grape pomace as an ingredient for potential functional biscuits: bioactive compound identification, in vitro bioactivity, food safety, and sensory evaluation

    Get PDF
    Grape pomace, the main by-product of wine process, shows high potential for the development of functional foods, being a natural source of bioactive compounds and dietary fiber. Thus, the present study proposes the development of five potential functional biscuits. The five formulations were achieved by varying the Tannat grape pomace powder (TGP, 10–20% w/w total wet dough) and sweetener sucralose (2–4% w/w total wet dough) content through a factorial design with central points. TGP microbiological and pesticides analysis were performed as a food safety requirement. Identification of bioactive compounds by HPLC-DAD-MS, in vitro bioactivity (total phenol content, antioxidant by ABTS and ORAC-FL, antidiabetic and antiobesity by inhibition of α-glucosidase and pancreatic lipase, respectively) and sensory properties of the biscuits were evaluated. TGP microbiological and pesticides showed values within food safety criteria. Sensory profiles of TGP biscuits were obtained, showing biscuits with 20% TGP good sensory quality (7.3, scale 1–9) in a cluster of 37 out of 101 consumers. TGP addition in biscuits had a significant (p < 0.05) effect on total phenolic content (0.893–1.858 mg GAE/g biscuit) and bioactive properties when compared to controls: 11.467–50.491 and 4.342–50.912 μmol TE/g biscuit for ABTS and ORAC-FL, respectively; inhibition of α-glucosidase and pancreatic lipase, IC50 35.572–64.268 and 7.197–47.135 mg/mL, respectively. HPLC-DAD-MS results showed all the identified phenolic compounds in 20/4% biscuit (TGP/sucralose%) were degraded during baking. Malvidin-3-O-(6′-p-coumaroyl) glucoside, (+)-catechin, malvidin-3-O-glucoside, and (−)-epicatechin were the main phenolic compounds (in descendent order of content) found. The bioactive properties could be attributed to the remaining phenolic compounds in the biscuits. In conclusion, TGP biscuits seemed to be a promising functional food with potential for ameliorating oxidative stress, glucose and fatty acids levels with good sensory quality
