Environmental sustainability assessment of municipal solid waste management through carbon footprint

One of the most challenging issues for building sustainable cities is the improvement of municipal solid waste management (MSWM), which requires a substantial effort to reduce its production and improve its different stages: collection (or pre-collection/containerization), transport and treatment. Each of these stages has environmental impacts stemming from the use of bags to hold the waste generated by residents in their homes, from the containers placed in public roads for drop-off, from the use of lorries or systems to transport waste to the processing plants, and from the construction and operation of plants to treat each waste fraction. In Europe, the Waste Framework Directive specifies Life Cycle Assessment (LCA) as a necessary policy-making tool, ensuring that impacts are assessed from cradle to grave, and avoiding ?hiding? impacts by moving them to other countries or stages of production/consumption. One of the environmental impacts evaluated is climate change (CC), in which greenhouse gas (GHG) emissions from the whole life cycle are calculated: carbon footprint (CF). This poster shows a methodology, based on LCA standards (ISO 14040 / 14044 / 14067), to calculate CF of MSWM. This methodology was applied to Madrid City

Loneliness, ageism and mental wellbeing in nursing homes during the COVID-19 pandemic

16th European Public Health Conference 2023 Our Food, Our Health, Our Earth: A Sustainable Future for Humanity Dublin, Ireland 8-11 November 2023.Background: The measures imposed during the COVID-19 pandemic, especially social distancing, had important effects on feelings of loneliness. The objective of this work is to assess the perception of loneliness in older adults living in nursing homes during the pandemic, how it has changed during the pandemic and its explanatory factors. Methods: The data come from the cross-sectional project "Protective environments of the elderly in health crises", carried out in the Community of Madrid (Spain) in 2021. The variables used were the frequency of feelings of loneliness and its change during the pandemic, as well as socio-demographic, health, emotional and contextual characteristics. Descriptive statistics and logistic regression analysis were calculated. Results: The sample consisted of 447 people; mean age was 83.8; 63.1% were women; half of the sample were widowed; 40% had an educative level lower than primary. Almost 3 out of 10 residents stated that they often or always/almost always felt alone. In the regression model, loneliness was negatively associated with age, number of medications, emotional balance, coping ability, self-perception of aging, and engaging in rewarding activities; while having a low assessment of mobility in the residential environment was positively associated. In addition, 28% of the participants who declared loneliness, also felt lonelier than before the pandemic. The variables associated with change in feelings of loneliness were age, self-perception of aging and a low assessment of the residential environment. Conclusions: The restrictions on mobility and social relationships during the COVID-19 epidemic have affected older people who were living in residences, with an increase in the feeling of loneliness related to demographic, emotional and contextual variables. Interventions on the design of residential spaces can mitigate the effects of isolation and loneliness related to health crises such as COVID-19 pandemic.S

Bex3 dimerization regulates NGF-dependent neuronal survival and differentiation by enhancing trkA gene transcription

The development of the nervous system is a temporally and spatially coordinated process that relies on the proper regulation of the genes involved. Neurotrophins and their receptors are directly responsible for the survival and differentiation of sensory and sympathetic neurons; however, it is not fully understood how genes encoding Trk neurotrophin receptors are regulated. Here, we show that rat Bex3 protein specifically regulates TrkA expression by acting at the trkA gene promoter level. Bex3 dimerization and shuttling to the nucleus regulate the transcription of the trkA promoter under basal conditions and also enhance nerve growth factor (NGF)-mediated trkA promoter activation. Moreover, qChIP assays indicate that Bex3 associates with the trkA promoter within a 150 bp sequence, immediately upstream from the transcription start site, which is sufficient to mediate the effects of Bex3. Consequently, the downregulation of Bex3 using shRNA increases neuronal apoptosis in NGF-dependent sensory neurons deprived of NGF and compromises PC12 cell differentiation in response to NGF. Our results support an important role for Bex3 in the regulation of TrkA expression and in NGF-mediated functions through modulation of the trkA promoter.This work was supported by Ministerio de Ciencia e Innovación Grant BFU2008-00162, by Ministerio de Economía y Competitividad Grant (BFU2011-22898 to J.C.A. and BFU2013-39394-P to P.P.), by a Marie Curie International Reintegration Grant within the European Community 7th Framework Programme, by the Consejería de Educación Grant SA074A08, and by a Consejería de Sanidad de Junta Castilla y León grant to J.C.A.

Differences in gene expression patterns between cultured and natural Haloquadratum walsbyi ecotypes

Solar crystallizer ponds are characterized by high population density with a relatively simple community structure in terms of species composition. The microbial community in the solar saltern of Santa Pola (Alicante, Spain), is largely dominated by the hyperhalophilic square archaeon Haloquadratum walsbyi. Here we studied metatranscriptomes retrieved from a crystallizer pond during the winter of 2012 and summer of 2014 and compared Hqr. walsbyi’s transcription patterns with that of the cultured strain Hqr. walsbyi HBSQ001. Significant differences were found between natural and the cultured grown strain in the distribution of transcript levels per gene. This likely reflects the adaptation of the cultured strain to the relative homogeneous growth conditions while the natural species, which is represented by multiple ecotypes, is adapted to heterogeneous environmental conditions and challenges of nutrient competition, viral attack, and other stressors. An important consequence of this study is that expression patterns obtained under artificial cultivation conditions cannot be directly extrapolated to gene expression under natural conditions. Moreover, we found 195 significantly differential expressed genes between the seasons, with 140 genes being higher expressed in winter and mainly encode proteins involved in energy and carbon source acquiring processes, and in stress responses.RR received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no. 818431 (SIMBA).

La educación física en la normativa provincial

La promulgación de la Ley Nacional de Educación Nº 26206, acaecida en el pasado 2006, dejo atrás la Ley Federal de Educación, sancionada en 1993, la cual mereció tantas opciones encontradas, dejando entre otras cuestiones un anárquico sistema educativo propagado a lo largo y ancho de nuestro país. Ahora bien dado nuestro sistema federal, y ante la presencia de una legislación nacional macro, las provincias comenzaron a normatizarse para sus jurisdicciones, así entonces nos encontramos que la Pcía de Bs. As., en el 2007, sanciono la Ley Nº 13688, la cual incorpora interesantes aspectos de acuerdo con las líneas directrices dadas por la Ley Nacional de Educación. Sobre los tópicos introducidos en la normativa provincial, nos dedicaremos a aquellas referidas al área de la Educación Física.Panel: "Deporte, Política y Estado".Departamento de Educación Físic

Representaciones sociales en torno a un programa de actividad física recreacional en espacios socioresidenciales vulnerables del Partido de La Matanza

En los últimos años, el Estado argentino ha comenzado a desarrollar un conjunto de Programas Sociales que desde un enfoque del derechos propone una acción dirigida a promover la actividad física y el juego recreativo en espacios sociales vulnerables. Estos programas encuentran fundamento en el amplio conocimiento construido en torno a la importancia que tiene en la niñez el logro de la socialización. En este artículo se presentan avances de investigación sobre un estudio de caso en torno al Programa “Actividad Física en Familia”, y en particular, las representaciones sociales construidas por niños/as entre 6 y 12 años y adultos de referencia residentes en tres espacios socio-residenciales de villa o asentamiento urbano del Municipio de La Matanza. Se analizan seis entrevistas en profundidad a niños/as y adultos referentes participantes y no participantes de dicho programa durante el primer cuatrimestre del 2012.Fil: Tuñón, Ianina.

A DNA vaccine encoding foot-and-mouth disease virus B and T-cell epitopes targeted to class II swine leukocyte antigens protects pigs against viral challenge

Development of efficient and safer vaccines against foot-and-mouth disease virus (FMDV) is a must. Previous results obtained in our laboratory have demonstrated that DNA vaccines encoding B and T cell epitopes from type C FMDV, efficiently controlled virus replication in mice, while they did not protect against FMDV challenge in pigs, one of the FMDV natural hosts. The main finding of this work is the ability to improve the protection afforded in swine using a new DNA-vaccine prototype (pCMV-APCH1BTT), encoding FMDV B and T-cell epitopes fused to the single-chain variable fragment of the 1F12 mouse monoclonal antibody that recognizes Class-II Swine Leukocyte antigens. Half of the DNA-immunized pigs were fully protected upon viral challenge, while the remaining animals were partially protected, showing a delayed, shorter and milder disease than control pigs. Full protection in a given vaccinated-pig correlated with the induction of specific IFNγ-secreting T-cells, detectable prior to FMDV-challenge, together with a rapid development of neutralizing antibodies after viral challenge, pointing towards the relevance that both arms of the immune response can play in protection. Our results open new avenues for developing future FMDV subunit vaccines.Fil: Borrego, Belén. No especifíca;Fil: Argilaguet, Jordi M.. Universitat Autònoma de Barcelona; EspañaFil: Pérez Martín, Eva.

Sociabilidad y modelos de identificación de deportistas juveniles expertos

Actualmente los procesos de construcción de la expertise deportiva son un campo fecundo para desarrollar programas que persigan un desarrollo integral del deportista. En ello la familia, los afectos y los referentes del deporte juegan un papel fundamental. Se trabajó con una muestra de 408 deportistas de entre 13 y 17 años de ambos sexos preclasificados para los Juegos Olímpicos de la Juventud de Buenos Aires 2018 encuestados anónima y voluntariamente. Se resalta el rol de la familia, la dinámica de las relaciones sociales construidas entorno al deporte y el desarrollo de la identidad deportiva de los jóvenes que se diferencian en algunos aspectos entre aquellos que practican distintos tipos de deportes y según el sexo. Este estudio avanza en el análisis del perfil psicológico del deportista joven y en la identificación de las competencias psicosociales necesarias para el desarrollo integral de los procesos de construcción del deporte de elite.Fil: Lavignolle, Brigida Ines.
