María L. Gallego, Isabel A. Pérez-Hernández, Rosario Palacios, Josefa Ruiz-Morales, Enrique Nu?o, Manuel Márquez, Jesús Santos
Open Journal of Internal Medicine (OJIM) , 2012, DOI: 10.4236/ojim.2012.21002
Abstract: Objective: To examine the association between elevated levels of red cell distribution width (RDW) and cardiovascular risk factors (CVRF) and metabolic syndrome (MS) in HIV-patients. Methods: Cross-sectional study including all asymptomatic HIV-outpatients under follow-up during 2007. Patients completed a questionnaire about CVRF, underwent a physical examination, and an 8-hour fasting blood analysis. Elevated RDW was defined as ≥75th percentile. Patients with and without an elevated RDW were compared. Results: 666 patients (79.3% men) were included: mean age 44.7 years, mean CD4 506/mm3 and 87.5% on antiretroviral therapy (85.3% with undetectable viral load). Mean RDW was 13.7% (range: 7.7% - 33.6%; 75th percentile, 14.1%). The prevalence per quartile of MS was 15.7%, 9.3%, 18.8% and 16.6% and of patients with CVRF > 20% was 8.4%, 4.0%, 4.4%, and 6.4%, respectively (p > 0.05); 23.4% of the patients had an elevated RDW (>14.1%). The top percentile of RDW was associated with AIDS (OR 1.6; 95% CI, 1.0 - 2.4; p = 0.02), detectable viral load (OR 1.5; 95% CI, 1.01 - 2.4; p = 0.04) and hypertension (OR 2.3; 95% CI, 1.4 - 4.0; p = 0.001). Conclusions: In HIV-outpatients, higher RDW is related with detectable viral load and with AIDS. Although it was associated with hypertension, we found no relation with MS nor with higher cardiovascular risk.

Abstract: Los sarcomas de la laringe son neoplasias que constituyen menos del 1% de los tumores malignos, y su tratamiento habitual es quirúrgico que incluye la laringectomía parcial o total y la cordectomía endoscópica con láser, con recurrencias de hasta 20%. Debido a experiencia positiva en nuestro país con la laringotomía transversa en casos de aritenoidectomía para tratar parálisis bilateral de las cuerdas vocales como consecuencia de tiroidectomía total, el propósito de este reporte fue el de informar el resultado obtenido con esta técnica de laringotomía transversa a un caso raro de sarcoma glótico en un médico de 47 a os que tenía cuatro meses de disfonía moderada sin disnea, disfagia ni estridor y sin historia de radioterapia o quimioterapia previas. La lesión fue evaluada por endoscopia y tomografía laríngea que mostraron un tumor del lado derecho de la glotis de 3 a 4 cm de tama o no ulcerado. El informe patológico fue de un fibrohistiocitoma maligno. Cinco a os después el paciente está bien y sin evidencia de enfermedad.

Memorias conformacionales en la predicción de estructura terciaria de polipéptidos
Ramón Gardu?o Juárez,Luis B. Morales
Revista de la Sociedad Química de México , 2003,
Abstract: Para reducir el espacio conformacional presente en la predicción de la estructura terciaria de polipéptidos, el cual crece exponencialmente con el número de residuos, hemos dise ado un algoritmo de búsqueda heurística que es robusto y que puede proporcionar estructuras cercanas a la nativa con relativa facilidad. Específicamente, hemos desarrollado un algoritmo genético híbrido (AGH) que usa números reales en lugar de bits para describir a los genes de cualquier cromosoma, y que incluye un operador de perfeccionamiento cuya función es reorientar la búsqueda hacia los individuos mejor adaptados. Al final de cada ciclo del AGH, un análisis de la población resultante indica la presencia de cúmulos bien definidos en los valores de ángulos de torsión para cada cromosoma. Estos segmentos corresponden a diferentes conformaciones de baja energía, y son relativamente constantes cada vez que se practica un nuevo experimento de AGH sobre la misma molécula. A estos segmentos les hemos llamado memorias conformacionales , y son usados como los límites de un espacio conformacional reducido dentro del cual se realiza la siguiente ronda del AGH. El empleo de las memorias conformacionales acelera y afina la localización de la estructura correspondiente al Mínimo Global de Energía (MGE). Este algoritmo ha sido empleado para localizar con éxito el MGE de la Met- y la Leuencefalina.

Informes de la Construccion , 2010,
Abstract: Experimental research was made in compressed soil block (BTC) piles. These specimens were reinforced with hexagonal mesh and welded wire mesh to determinate its mechanics characteristics by means of axial and diagonal compression, and flexion tests. We made experimental assays in accord with Mexican Code specifications of NTCM(1) and UNAM(2) Engineering Institute researchers. In axial compression test, the piles reinforced with welded wire mesh had a significant increase in maxim admissible load (39%) but had not in masonry strength (4%). In diagonal compression test, the reinforced groups had significant increases in both, load capacity (90-125%) and masonry strength (60-83%). The strength and deformation capacity were higher in specimens reinforced with welded wire mesh. In the flexion test had similar results. Although the compression, shear and flexion design parameters was determinate, it’s important and necessary to make more tests to corroborate these results. Se realizó una investigación experimental en pilas de bloques de tierra compactados (BTC) reforzadas con malla hexagonal y malla electrosoldada para determinar la influencia del refuerzo, mediante ensayes de compresión axial, compresión diagonal y flexión lateral, según lo especifican las Normas Técnicas Complementarias para Mampostería (NTCM(1) y UNAM(2)) del DF, en México. En el ensayo a compresión axial, se determinó que la carga máxima admisible se incrementó significativamente en el grupo reforzado con malla electrosoldada (39%), no así la resistencia (4%). En el ensaye a compresión diagonal, el incremento en la carga máxima admisible y resistencia fue significativo para los dos grupos reforzados, de 90 a 125% y de 60 a 83% respectivamente. A flexión lateral los incrementos fueron altamente significativos para el grupo reforzado con malla electrosoldada. Aunque se determinaron los parámetros de dise o a compresión, cortante y flexión del BTC, es importante realizar mas ensayes para corroborar estos resultados.

Francisco Javier Barbero Juárez,Francisco José Martín Ca?ete,Vicenta Galbis Valero,Josefa García López
NURE Investigación , 2004,
Abstract: One of the most important problems that a patient with a colostomy has to face after surgery is the intestinal continence. This lead these patients to experience not only a series of physical changes but also hygienic, dietetic, social, etc. As nurses, we must learn how to detect the needs of these patients in order to offer them an appropriate attention to improve their quality of life. Our aim is to assess if the irrigation technique (IT) as a method for intestinal continence improves the quality of life in these patients. Methodology: A Pretest-postest study without control group was carried out in order to evaluate the usefulness of IT to improve the quality of life in patients with colostomy. Following a normalized protocol, the technique was taught to patients whose quality of life was evaluated before and after the application of IT. Results: Quality of life rate before intervention was 54,2% and reached 77,3% (statistically significant) once the patient has used IT for two months. Conclusions: IT is associated with a remarkable improvement in the quality of life of patientes with colostomy. This improvement is reflected in the eight dimensions analysed: psychological welfare, physical welfare, body image, pain, sexual activity, nutrition, social preoccupations and device handling.

Abstract:

Tomato is one the most important vegetables worldwide and mineral nutrition in tomato crops is considered as the second most important factor in crop management after water availability. Mathematical modeling techniques allow us to design strategies for nutrition management. In order to generate the necessary information to validate and calibrate a dynamic growth model, two tomato crop cycles were developed. Several mineral analyses were performed during crop development to determine the behavior of N, P, K, Ca, Mg and S in different organs of the plant. Regression models were generated to mimic the behavior of minerals in tomato plants and they were included in the model in order to simulate their dynamic behavior. The results of this experiments showed that the growth model adequately simulates leaf and fruit weight (EF > 0.95 and Index > 0.95). As for harvested fruits and harvested leaves, the simulation was less efficient (EF < 0.90 and Index < 0.90). Simulation of minerals was suitable for N, P, K and S as both, the EF and the Index, had higher values than 0.95. In the case of Ca and Mg, simulations showed indices below 0.90. These models can be used for planning crop management and to design more appropriate fertilization strategies.
