“APLICACIÓN DE LA NUTRICIÓN EN LA ALIMENTACIÓN SUSTENTABLE Y EL PAPEL DEL NUTRIÓLOGO EN EL CUIDADO DEL MEDIO AMBIENTE”

La sustentabilidad se refiere a todo aquello que contribuye con las necesidades de las generaciones presentes sin colocar en riesgo las necesidades de las futuras generaciones. Esto quiere decir que se busca la manera de aprovechar de la mejor manera posible, los recursos con los que se cuenta, procurando que esos mismos se renueven o no se exploten en demasía para que futuras generaciones puedan aprovechar sus beneficios también. En cuanto a la nutrición, la sustentabilidad pretende que la dieta actual cumpla con los requisitos de ser equilibrada, variada, completa, suficiente, inocua y adecuada para cada individuo, procurando que los alimentos sean de la mayor calidad posible y buscando maneras de que no se afecte al ecosistema en la producción de los mismos. Por lo tanto, los hábitos alimenticios deben ser considerados saludables desde un punto de vista nutricional y ambientalmente compatibles. La salud es la principal preocupación de todos los seres humanos y la alimentación es parte inseparable de una buena salud. La producción y venta de alimentos ecológicos, y por lo tanto sustentables, vienen a dar respuestas a los consumidores y a la cada vez mayor atención que se presta a la alimentación en la actualidad. La alimentación sustentable consiste, principalmente, en buscar la manera de consumir productos orgánicos o ecológicos. Este tipo de productos son aquellos que son producidos sin pesticidas ni agroquímicos de síntesis y que son controlados durante toda la cadena productiva, de tal forma que se garantizan alimentos sanos para el consumidor y con grandes beneficios al ambiente antes, durante y después de su producción

Host-Microbiome Interaction and Cancer: Potential Application in Precision Medicine

It has been experimentally shown that host-microbial interaction plays a major role in shaping the wellness or disease of the human body. Microorganisms coexisting in human tissues provide a variety of benefits that contribute to proper functional activity in the host through the modulation of fundamental processes such as signal transduction, immunity and metabolism. The unbalance of this microbial profile, or dysbiosis, has been correlated with the genesis and evolution of complex diseases such as cancer. Although this latter disease has been thoroughly studied using different high-throughput technologies, its heterogeneous nature makes its understanding and proper treatment in patients a remaining challenge in clinical settings. Notably, given the outstanding role of host-microbiome interactions, the ecological interactions with microorganisms have become a new significant aspect in the systems that can contribute to the diagnosis and potential treatment of solid cancers. As a part of expanding precision medicine in the area of cancer research, efforts aimed at effective treatments for various kinds of cancer based on the knowledge of genetics, biology of the disease and host-microbiome interactions might improve the prediction of disease risk and implement potential microbiota-directed therapeutics. In this review, we present the state of the art of sequencing and metabolome technologies, computational methods and schemes in systems biology that have addressed recent breakthroughs of uncovering relationships or associations between microorganisms and cancer. Together, microbiome studies extend the horizon of new personalized treatments against cancer from the perspective of precision medicine through a synergistic strategy integrating clinical knowledge, high-throughput data, bioinformatics and systems biology

La Constitución Política de los Estados Unidos Mexicanos 1917-2017 a 100 años

resultado de la primera revolución social del siglo XX fue la Constitución Política de los Estados Unidos Mexicanos, documento que plasmó las aspiraciones de toda una nación, marcando el rumbo de nuestro país hacia la democracia. Gracias a la Carta Magna hoy tenemos garantizados amplios derechos y podemos ejercer plenamente nuestras libertades. Celebro que la Universidad Autónoma del Estado de México conmemore los cien años de nuestra Constitución con la publicación de este libro, elaborado por un grupo multidisciplinario de investigadores, pertenecientes a diversas instituciones educativas del país, que analizan los diferentes artículos de la Constitución de 1917, desde los ámbitos histórico, filosófico, jurídico, educativo y social. Para el Gobierno del Estado de México, un libro conmemorativo de nuestra Carta Magna es invitación a reflexionar sobre las características de nuestras instituciones, así como la conveniencia de mantener o reformar sus artículos para continuar respondiendo a las necesidades de la ciudadanía. En cada propuesta de este libro, desde sus respectivos campos de estudio, los autores analizan los retos de la sociedad actual; además en su lectura e interpretación demuestran que los 136 artículos no son letra muerta, siguen vigentes

System controls of coastal and open ocean oxygen depletion

The epoch of the Anthropocene, a period during which human activity has been the dominant influence on climate and the environment, has witnessed a decline in oxygen concentrations and an expansion of oxygen-depleted environments in both coastal and open ocean systems since the middle of the 20th century. This paper provides a review of system-specific drivers of low oxygen in a range of case studies representing marine systems in the open ocean, on continental shelves, in enclosed seas and in the coastal environment. Identification of similar and contrasting responses within and across system types and corresponding oxygen regimes is shown to be informative both in understanding and isolating key controlling processes and provides a sound basis for predicting change under anticipated future conditions. Case studies were selected to achieve a balance in system diversity and global coverage. Each case study describes system attributes, including the present-day oxygen environment and known trends in oxygen concentrations over time. Central to each case study is the identification of the physical and biogeochemical processes that determine oxygen concentrations through the tradeoff between ventilation and respiration. Spatial distributions of oxygen and time series of oxygen data provide the opportunity to identify trends in oxygen availability and have allowed various drivers of low oxygen to be distinguished through correlative and causative relationships. Deoxygenation results from a complex interplay of hydrographic and biogeochemical processes and the superposition of these processes, some additive and others subtractive, makes attribution to any particular driver challenging. System-specific models are therefore required to achieve a quantitative understanding of these processes and of the feedbacks between processes at varying scales

High-Sustained Concentrations of Organisms at Very low Oxygen Concentration Indicated by Acoustic Profiles in the Oxygen Deficit Region Off Peru

International audienceThe oxygen deficient mesopelagic layer (ODL) off Peru has concentrations below 5 μmol O 2 kg –1 and is delimited by a shallow upper oxycline with strong vertical gradient and a more gradual lower oxycline ( lOx ). Some regions show a narrow band of slightly increased oxygen concentrations within the ODL, an intermediate oxygen layer ( iO 2 ). CTD, oxygen and lowered Acoustic Doppler Current Profiler (LADCP, 300 kHz) profiles were taken on the shelf edge and outside down to mostly 2000 m. We evaluate here the acoustic volume backscatter strength of the LADCP signal representing organisms of about 5 mm size. Dominant features of the backscatter profiles were a minimum backscatter strength within the ODL, and just below the lOx a marked backscatter increase reaching a maximum at less than 3.0 μmol O 2 kg –1 . Below this maximum, the acoustic backscatter strength gradually decreased down to 1000 m below the lOx . The backscatter strength also increased at the iO 2 in parallel to the oxygen concentration perturbations marking the iO 2 . These stable backscatter features were independent of the time of day and the organisms represented by the backscatter had to be adapted to live in this microaerobic environment. During daylight, these stable structures were overlapped by migrating backscatter peaks. Outstanding features of the stable backscatter were that at very low oxygen concentrations, the volume backscatter was linearly related to the oxygen concentration, reaching half peak maximum at less than 2.0 μmol O 2 kg –1 below the lOx , and the depth-integrated backscatter of the peak below the lOx was higher than the integral above the Ox. Both features suggest that sufficient organic material produced at the surface reaches to below the ODL to sustain the major fraction of the volume backscatter-producing organisms in the water column. These organisms are adapted to the microaerobic environment so they can position themselves close to the lower oxycline to take advantage of the organic particles sinking out of the ODL

Understanding the impact of climate change on the oceanic circulation in the Chilean island ecoregions

International audienceAbstract Transient mesoscale oceanic eddies in Eastern Boundary Upwelling Systems are thought to strongly affect key regional scale processes such as ocean heat transport, coastal upwelling and productivity. Understanding how these can be modulated at low-frequency is thus critical to infer their role in the climate system. Here we use 26 years of satellite altimeter data and regional oceanic modeling to investigate the modulation of eddy kinetic energy (EKE) off Peru and Chile by ENSO, the main mode of natural variability in the tropical Pacific. We show that EKE tends to increase during strong Eastern Pacific (EP) El Niño events along the Peruvian coast up to northern Chile and decreases off central Chile, while it is hardly changed during Central Pacific El Niño and La Niña events. However the magnitude of the EKE changes during strong EP El Niño events is not proportional to their strength, with in particular the 1972/1973 El Niño event standing out as an extreme event in terms of EKE increase off Peru reaching an amplitude three times as large as that during the 1997/1998 El Niño event, and the 2015/2016 El Niño having instead a weak impact on EKE. This produces decadal changes in EKE, with a similar pattern than that of strong EP El Niño events, resulting in a significant negative (positive) long-term trend off Peru (central Chile)
