    Evaluation of inulin extracted from Mexican wild dahlias (Dahlia coccinea Cav.)

    Santana Legorreta S1, A Villanueva-Carvajal2, EJ Morales-Rosales2, A Laguna-Cerda2, A Dominguez-Lopez2

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 63-70, 2016, DOI:10.32604/phyton.2016.85.063

    Abstract The Dahlia (Dahlia coccinea Cav.) is a plant that has been cultivated and genetically improved due to its ornamental importance; anyhow, its radical system accumulates reserve carbohydrates in the form of inulin and other fructans. Inulin is considered a part of the dietetic fiber from vegetable food sources, and it is also considered as a prebiotic compound. Inulin is extracted mainly from chicory and artichoke through different separation methods being Dahlia’s tubers an interesting option for industrial utilization. The aims of this study were to (1) propose a simple extraction method of inulin from Dahlia’s tubers,… More >

    Natural pollution (As, F) and eutrofication (N, P) in the basin of El Divisorio stream, Argentina

    Espósito ME1,3, MdelC Blanco1, ME Sequeira2,4, JD Paoloni3, SN Fernández2, NM Amiotti1,4, SL Díaz1

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 51-62, 2016, DOI:10.32604/phyton.2016.85.051

    Abstract The interrelation between hydrochemistry and hydrodinamics was analyzed in the basin of El Divisorio stream. This was to gain undestanding in the magnitude, distribution of toxic ions (As, F) and behaviour in the discharge of main nutrients (P, N) contributing to the eutrofication of Paso de las Piedras Dam. During two years, 47 sites were sampled determining several parameters: geographical position for each sampling point, phreatic level depth, and As, F, PO4 and N-NO3 concentrations. Repeated measures, Fisher test, correlation and regression analysis were applied to all variables. Highly significant space and time differences (P<0.01) with… More >

    Productive efficiencies in corn, bean and squash (Cucurbita pepo L.) associations, intercropped with rows of fruit trees

    Molina-Anzures MF1, JL Chávez-Servia2, A Gil-Muñoz1, PA López1, E Hernández-Romero1, E Ortiz-Torres1

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 36-50, 2016, DOI:10.32604/phyton.2016.85.036

    Abstract Mesoamerican agrosystem ‘milpa’ is the association of maize, beans (Phaseolus sp.) and squash (Cucurbits sp.) in the same space and time. It is characterized by the production of a large diversity of species in small areas, but currently its use tends to decrease because of technological introductions of monocultures. In this work, the yield and productive efficiency of the association maize, beans and squash, intercropped with fruit tree rows were evaluated in two locations from Puebla, Mexico, through 32 experimental treatments clustered in three agrosystems. They were: triple associations of maize-beans-squash intercropped with fruit trees, double… More >

    Floral differentiation and growth rhythm of rhizome buds of the spring ephemeroid plant Adonis amurensis Regel et Radde

    Liu XL1,2, JH Li2,3, JY Zhu2, YF Yang1

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 297-304, 2016, DOI:10.32604/phyton.2016.85.297

    Abstract Spring ephemeroid plants complete their aboveground reproduction and growth during the short growing season, and may go dormant subsequently underground. Little is known about the underground dormancy and biological activities of the plants. In this study, we observed organogenesis and growth rhythm of rhizome buds of Adonis amurensis Regel et Radde, a spring ephemeroid plant from the Changbai Mountains in northeastern China. Our results showed that A. amurensis did not go through summer dormancy, but started producing mixed buds on rhizomes soon after the aboveground parts had died. The buds grew in length and diameter following an More >

    Quality and capsaicinoid concentration on genotypes of Serrano pepper (Capsicum annuum L.) produced under organic fertilization

    Valadez Sánchez YM1, E Olivares Sáenz1, RE Vázquez Alvarado1, JR Esparza-Rivera3, P Preciado-Rangel4, RD Valdez-Cepeda5, JL García-Hernandez2

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 21-26, 2016, DOI:10.32604/phyton.2016.85.021

    Abstract The aim of this study was to evaluate the effect of three organic fertilization sources on the agronomic and biochemical qualities of four genotypes of Serrano pepper. The experiment was performed at the field in Gómez Palacio, Durango (México). The capsaicinoids (CAP´s) are compounds responsible of the pungency of the peppers, and they are valuable for health and food and cosmetic food. The organic treatments applied were: solarized bovine manure (60 Mg/ha), vermicompost (10 Mg/ha) and poultry manure (5 Mg/ ha). A non-fertilized treatment was used as control. The evaluated variables were: length, diameter and… More >

    Use of diammonium phosphate on wheat grown in southwestern Buenos Aires (Argentina)

    Ron MM, T Loewy

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 15-20, 2016, DOI:10.32604/phyton.2016.85.015

    Abstract In the southwest of Buenos Aires Province (Argentina), nitrogen (N) and phosphorus (P) deficiencies are important wheat yield limiting factors. There is an information gap regarding differences between single element and binary N-P sources. The objective of this paper was to develop a general model for N-P fertilization in the area that also quantified diammonium phosphate (DAP) effect and its interactions with N-urea, applied at sowing or tillering, as compared with triple superphosphate (TSP). Between 1984 and 1985, 13 experiments were carried out in farmer’s fields N. With the yield data for each experiment, a… More >

    Single-point and Filtered Relative Position Estimation for Visual Docking

    Dylan Conway1, Daniele Mortari2

    CMES-Computer Modeling in Engineering & Sciences, Vol.111, No.2, pp. 147-169, 2016, DOI:10.3970/cmes.2016.111.147

    Abstract This paper presents a new method to estimate position from line-ofsight measurements to known targets when attitude is known. The algorithm has two stages. The first produces a closed-form unbiased estimate for position that does not account for the measurement error covariance. The second stage is iterative and produces an estimate of position that explicitly accounts for the measurement error covariance and the coupling between measurement error and sensor-to-target distance. The algorithm gives an accurate estimate of both position and the corresponding position error covariance and has a low computational cost. The computational complexity is O(n) More >

    Cardiac ischemic preconditioning prevents dystrophin proteolysis by MMP-2 inhibition

    M. Rodríguez, B. Buchholz, V. D’Annuzio, M. Donato, G.E. González, M. A. Goyeneche, T. Mazo, V. Pérez, L. Wilensky, R.J. Gelpi*

    BIOCELL, Vol.40, No.1, pp. 43-46, 2016, DOI:10.32604/biocell.2016.40.043

    Abstract Dystrophin is a membrane-associated protein responsible for structural stability of the sarcolemma in cardiac myocytes and is very sensitive to ischemic damage. The goal of our study was to determine if ischemic preconditioning could prevent dystrophin breakdown through inhibition of matrix metalloproteinase-2 (MMP-2) activity. Isolated rabbit hearts were subjected to global ischemia with or without reperfusion in order to evaluate if dystrophin is preserved by ischemic preconditioning through MMP-2 inhibition. Ischemic preconditioning significantly reduced the infarct size induced by 30 min of ischemia and 180 min of reperfusion. Importantly, it also diminished dystrophin proteolysis and More >

    Heart mitochondrial dysfunction in diabetic rats

    S.S. Bombicino*, D.E. Iglesias, I.A. Rukavina Mikusic, A. Boveris, L.B. Valdez

    BIOCELL, Vol.40, No.1, pp. 7-10, 2016, DOI:10.32604/biocell.2016.40.007

    Abstract Diabetic cardiomyopathy, i.e. the ventricular dysfunction in the absence of hypertension or coronary arterial disease, is a common complication of diabetes mellitus that leads to a heightened risk of heart failure and death among diabetic patients. This contractile dysfunction could be associated to mitochondrial dysfunction, in which mitochondrial biogenesis could emerge as a compensatory mechanism triggered in response to hyperglycemia. It has been proposed that nitric oxide synthase activities with enhanced NO production are involved in this process. Alterations in the contractile response and lusitropic reserve were observed in streptozotocin diabetic rats after β-adrenergic stimuli. Additionally,… More >
