    Este documento está dedicado al recuerdo de Fernando de Buen, a quién podríamos considerar como uno de los primeros “ictiólogos iberoamericanos”. En este caso nos encontramos con un profesional que, por la locura de una guerra fratricida, tuvo que dejar su patria y trasladarse al continente americano, residiendo inicialmente en México dónde adopta su ciudadanía. Posteriormente viaja a Sudamérica para trabajar en Uruguay y luego en Chile. En esa extensa travesía generó parte de su legado, dejando aportes substanciales para el crecimiento y consolidación de la ictiología neotropical. Por ello, a más de cincuenta años de su desaparición, junto a la invalorable colaboración de los colegas de Chile, España, México y Uruguay, concretamos este modesto archivo con la idea de que su figura y su obra no se pierdan en la “bruma de los tiempos” y que las jóvenes generaciones conozcan a quiénes abrieron los surcos de nuestra disciplina aún, como en este caso, llevando consigo el dolor y la angustia del destierro

    En el presente trabajo se presenta la serie de acciones realizadas para una labor de consultoría en una Mypes. El objetivo principal de este proyecto consiste en proporcionar a la MYPE un medio para contribuir a su consolidación, a través de un modelo de consultoría con intervención de estudiantes universitarios que da origen al nombre de “Consultorías Universitarias” y que es fomentado por el Centro Universidad Empresa del CUE. Primero se realizó un análisis contextual para entender el mercado y regulación de acción, posteriormente se realizó un diagnostico donde se encontró que la empresa estaba en un nivel confiable de maduración y que el problema principal había sido su crecimiento descontrolado basado en una deficiente planeación estratégica. Para favorecer al crecimiento controlado de la Mypes el equipo de trabajo se enfocó en realizar labores de estandarización a través de: diferentes manuales de procedimientos en las áreas de recursos humanos, mercadotecnia y administración, ayudar a entender la importancia de una planeación con objetivos operativos y estratégicos, además a lograr enfocar la acción social de la A.C. a mercados que podrían verse beneficiados en una relación ganar-ganar y a sus finanzas que deben tener un marco especifico de ganancia y reinversión. Los resultados de la implementación indican que la empresa logro adecuar su labor práctica a su área organizacional y sobre todo tener claro cómo, por qué, cuándo y dónde iban a enfocar sus actividades para el desarrollo.ITESO, A.C

    Twenty years of ground-based NDACC FTIR spectrometry at Izaña Observatory-overview and long-term comparison to other techniques

    High-resolution Fourier transform infrared (FTIR) solar observations are particularly relevant for climate studies, as they allow atmospheric gaseous composition and multiple climate processes to be monitored in detail. In this context, the present paper provides an overview of 20 years of FTIR measurements taken in the framework of the NDACC (Network for the Detection of Atmospheric Composition Change) from 1999 to 2018 at the subtropical Izaña Observatory (IZO, Spain). Firstly, long-term instrumental performance is comprehensively assessed, corroborating the temporal stability and reliable instrumental characterization of the two FTIR spectrometers installed at IZO since 1999. Then, the time series of all trace gases contributing to NDACC at IZO are presented (i.e. C2_{2}H6_{6}, CH4_{4}, ClONO2_{2}, CO, HCl, HCN, H2_{2}CO, HF, HNO3_{3}, N2_{2}O, NO2_{2}, NO, O3_{3}, carbonyl sulfide (OCS), and water vapour isotopologues H2_{2}16^{16}O, H2_{2}18^{18}O, and HD16^{16}O), reviewing the major accomplishments drawn from these observations. In order to examine the quality and long-term consistency of the IZO FTIR observations, a comparison of those NDACC products for which other high-quality measurement techniques are available at IZO has been performed (i.e. CH4_{4}, CO, H2_{2}O, NO2_{2}, N2_{2}O, and O3_{3}). This quality assessment was carried out on different timescales to examine what temporal signals are captured by the FTIR records, and to what extent. After 20 years of operation, the IZO NDACC FTIR observations have been found to be very consistent and reliable over time, demonstrating great potential for climate research. Long-term NDACC FTIR data sets, such as IZO, are indispensable tools for the investigation of atmospheric composition trends, multi-year phenomena, and complex climate feedback processes, as well as for the validation of past and present space-based missions and chemistry climate models

    Innate and adaptive immune defects associated with lower SARS-CoV-2 BNT162b2 mRNA vaccine response in elderly people

    The immune factors associated with impaired SARS-CoV-2 vaccine response in the elderly are mostly unknown. We studied old and young people vaccinated with SARS-CoV-2 BNT162b2 mRNA before and after the first and second dose. Aging was associated with a lower anti-RBD IgG levels and a decreased magnitude and polyfunctionality of SARS-CoV-2 specific T cell response. The dramatic decrease in thymic function in the elderly, which fueled alteration in T cell homeostasis, and lower CD161+ T cell levels were associated with decreased T cell response two months after vaccination. Additionally, a deficient dendritic cell (DC) homing, activation and Toll like receptor (TLR)-mediated function, along with a proinflammatory functional profile in monocytes, were observed in the elderly, which was also related to lower specific T cell response after vaccination. These findings might be relevant for the improvement of the current vaccination strategies and for the development of new vaccine prototypes.This study was funded by Consejeria de Transformacion Economica, Industria, Conocimiento y Universidades, Junta de Andalucia (CV20-85418 and P20_00906, DOC-01659 and DOC-00963); Consejeria de Salud, Junta de Andalucia (RH-0037-2020), Instituto de Salud Carlos III (CP19/00159, FI17/00186, FI19/00083, PI19/01172, CM20/00243) Fondos FEDER, and National Spanish Research Council (CSIC).N

    Immune defects associated with lower SARS-CoV-2 BNT162b2 mRNA vaccine response in aged people

    The immune factors associated with impaired SARS-CoV-2 vaccine response in elderly people are mostly unknown. We studied individuals older than 60 and younger than 60 years, who had been vaccinated with SARS-CoV-2 BNT162b2 mRNA, before and after the first and second dose. Aging was associated with a lower anti–RBD IgG levels and a decreased magnitude and polyfunctionality of SARS-CoV-2–specific T cell response. The dramatic decrease in thymic function in people > 60 years, which fueled alteration in T cell homeostasis, and their lower CD161+ T cell levels were associated with decreased T cell response 2 months after vaccination. Additionally, deficient DC homing, activation, and TLR-mediated function, along with a proinflammatory functional profile in monocytes, were observed in the > 60-year-old group, which was also related to lower specific T cell response after vaccination. These findings might be relevant for the improvement of the current vaccination strategies and for the development of new vaccine prototypes.This work was supported by the Consejería de Transformación Económica, Industria, Conocimiento y Universidades, Junta de Andalucía grants CV20-85418 and P20_00906 and by research contracts DOC-01659 and DOC-00963, as well as by Consejería de Salud, Junta de Andalucía research contract RH-0037-2020 and Instituto de Salud Carlos III CP19/00159, FI17/00186, FI19/00083, PI19/01127, and CM20/00243 from Fondos FEDER.
