Abstract: La anemia nutricional durante el embarazo es consecuencia de una dieta inadecuada y bajo contenido de hierro, el cual es un alto factor de riesgo para la salud materno infantil.Con el presente estudio se determinó la prevalencia de la anemia nutricional materna en los Centros de salud Solomon Klein y el de Sarcobamba en el periodo de enero del 2010 a enero del 2011. Es un estudio retrospectivo tipo descriptivo transversal donde se utilizó las variables de niveles de hemoglobina y grado de anemia. Se revisaron 98 Historias clínicas prenatales, en el centro de Sarcobamba ,137 en el centro Solomon Klein de mujeres embarazadas que asistieron a sus tres controles y se realizaron una prueba hematológica. La prevalencia de anemia nutricional en mujeres embarazadas fue de 40,8%, los niveles de anemia fueron 65,3% anemia leve, el 28,7% anemia moderada y el 5,9% anemia grave. Por lo tanto se concluye que la anemia nutricional en el embarazo aún sigue teniendo una alta prevalencia en los centros de primer nivel y sigue siendo uno de los retos en salud materna infantil que se debe vencer en los controles prenatales con un tratamiento oportuno y eficaz.

Fractional Integration and Fractional Differentiation for d-dimensional Jacobi Expansions
Cristina Balderrama,Wilfredo Urbina
Mathematics , 2006,
Abstract: In this paper we consider an alternative orthogonal decomposition of the space $L^2$ associated to the $d$-dimensional Jacobi measure and obtain an analogous result to P.A. Meyer's Multipliers Theorem for d-dimensional Jacobi expansions. Then we define and study the Fractional Integral, the Fractional Derivative and the Bessel potentials induced by the Jacobi operator. We also obtain a characterization of the potential spaces and a version of Calderon's reproduction formula for the d-dimensional Jacobi measure.
Water Adsorption Isotherms of Amaranth (Amaranthus caudatus) Flour  [PDF]

Water sorption isotherms are unique for individual food materials and can be used directly to predict shelf life and determine proper storage conditions. In this context, the aim of this study was to determine the moisture adsorption isotherms of amaranth flour at 15℃, 25℃ and 35℃ in a range of water activity from 0.1 to 0.9. Experimental data were modeled using five equations commonly applied in the foods field. The goodness of the fit for each isotherm model was evaluated through the coefficient of determination, the variance due to error and the confidence interval of the estimated parameters. All models can predict the adsorption isotherms of amaranth flour, but the GAB equation gives a better understanding of the observed sorption behavior. Estimated adsorption monolayer water contents ranged from 6.4 g to 7.2 g of water per 100 g of dry material. It was observed by a weak dependence of water activity with temperature. For ensuring microbiological stability, water content in amaranth flour should not be higher than 13 g of water per 100 g of dry material.

Mecanismo antidiurético en Rhodnius Prolixus (Stal, 1859) (Hemiptera, Reduviidae)
Gómez, Ivonne;Balderrama, Norberto;
Memórias do Instituto Oswaldo Cruz , 1986, DOI: 10.1590/S0074-02761986000400012
Abstract: an antidiuretic mechanism is proposed for rhodnius prolixus, whose activity is manifested when the diuretic phase has terminated and is maintained until the insect has fed again. presumably this mechanism acts at the level of the proximal rectal sphincter and is inhibited by ingestion, mechanical distension of the gut and central desinhibition by decapitation. it is suggested that the antidiuretic activity is maintained by the nervous system and is modified when there is distention of the gut or when the nervous signal is interrupted by decapitacion. it is demonstrated that the excretion of urine in r. prolixus is not controlled exclusively by the diuretic hormone, but rather that factors not linked to the haemolvmph maintain the insects in a diuretic or nondiuretic state.

Existence and multiplicity of periodic solutions for a hematopoiesis model

Abstract: A general nonautonomous Mackey-Glass equation for the regulation of the hematopoiesis with several non-constant delays is studied. Using topological degree methods, we prove the existence and multiplicity of positive periodic solutions.
