Estructura económica: Análisis del mercado interno del frijol rojo en Nicaragua durante el periodo 2009-2013
El Frijol es uno de los alimentos básicos en la dieta de la población nicaragüense. A diferencia de otros granos, la producción de frijol se ha caracterizado en los últimos años por ser auto suficiente y así cada día toma mayor preeminencia en la economía nacional, pero se ha visto perjudicados por los fenómenos naturales y altos costos que afectan a los campesinos que lo cultivan. La mayoría de los productores tuvieron pérdidas en el ciclo de primera debido a las fuertes sequía que ocurriero

Generation and selection of anti-flagellin monoclonal antibodies useful for serotyping Salmonella enterica
In developing countries, bacterial acute gastroenteritis continues to be an important cause of morbidity and mortality among young children. Salmonellosis constitutes a major cause of infectious enteritis worldwide, most of them associated to the consumption of contaminated food products. Traditionally, Salmonella has been classified in serovars based on varieties of O and H surface antigens. In the present work we generated and characterized a panel of anti-flagellin monoclonal antibodies (MAbs) in order to select antibodies useful for detecting the H surface antigen. Four different MAbs were obtained by somatic hybridization of splenocytes. We found two MAbs that recognised regions of flagellin conserved among different Salmonella serovars. Other two MAbs recognised structures restricted to Salmonella enterica sv. Typhimurium, being one of them suitable for agglutination tests. Using a diverse panel of S. enterica serovars with different H antigen varieties we confirmed that this MAb agglutinates specifically S. Typhimurium (antigenic formula: 4,12:i:1,2) or other serovars expressing flagellar factor i. In conclusion, we generated a valuable immunochemical tool to be used in simple assays for serotyping of epidemiologically relevant strains. The capacity to characterize specific strains and determine the primary sources of Salmonella contamination generate valuable information of the epidemiology of this microorganism, contributing to the improvement of public health.Fil: Hiriart, Yanina.

Confined photon modes with triangular symmetry in hexagonal microcavities in 2D photonic Crystals
We present theoretical and experimental studies of the size and thickness
dependencies of the optical emission spectra from microcavities with hexagonal
shape in films of two-dimensional photonic crystal. A semiclassical plane-wave
model, which takes into account the electrodynamic properties of quasi-2D
planar photonic microcavity, is developed to predict the eigenfrequencies of
the confined photon modes as a function of both the hexagon-cavity size and the
film thickness. Modes with two different symmetries, triangular and hexagonal,
are critically analyzed. It is shown that the model of confined photon modes
with triangular symmetry gives a better agreement between the predicted
eigenmodes and the observed resonances.Comment: 14 pages, 6 figure
Is contact with birth parents beneficial to children in non-kinship foster care? A scoping review of the evidence
Many children in non-kinship foster care maintain contact with their birth parents, although debate continues
about whether or not, or under what circumstances, it is beneficial to the child. In this scoping review we analyze
the findings of studies conducted over the past two decades that have specifically examined face-to-face contact
with birth parents for children in non-kinship foster care, our aim being to determine more clearly when it may
contribute positively to the child’s well-being. The review was conducted in accordance with PRISMA-ScR
guidelines and involved a search of nine electronic databases. A total of 21 studies met the criteria for inclu-
sion in the review, namely primary studies analyzing one or more aspects of these contact visits, written in
English or Spanish, and published during the period 1997–2022. In analyzing these studies we grouped their
findings according to four broad areas of interest: characteristics of contact visits, appraisal of visits by families
and professionals, relationship between contact and fostering outcomes, and impact of contact on children. The
four main conclusions we draw from the review are: a) surprisingly few studies have specifically examined the
effects of face-to-face contact with birth parents in non-kinship foster care; b) the findings to date are neither
conclusive nor generalizable, although they are not generally encouraging; c) under the right circumstances (e.g.,
adequate supervision, conducted in a context of emotional security for the child), contact can contribute to the
child’s well-being and increase the likelihood of family reunification; and d) more robust research is needed to
guide the development of interventions that can improve parent–child relationships and the quality of contact
