    Analizar los procesos de gesti贸n y beneficios que trae consigo la implementaci贸n dela contabilidad ambiental en las empresas del sector textil en ColombiaLa contabilidad ambiental ha demostrado serun 谩rea de muy poco conocimiento para las empresas de los diferentes sectores econ贸micos del pa铆s, puesto que hoy en d铆a son muy limitadaslas organizaciones que implementan dentro de sus pol铆ticasempresarialeslos diferentes rubrosa tener en cuenta dentro del desarrollo de gesti贸n ambiental;al igual que el desconocimiento que tienen de los beneficios tributarios que esto conlleva; por otro lado, es claro determinar que dentro del proceso productivo de toda empresa se est谩n generando afectaciones a la sociedad en cuanto al uso excesivo de losrecursos naturales trayendo como consecuencia la generaci贸n, destrucci贸n y contaminaci贸n ambiental.Por tal raz贸n, y con el fin de abordar la problem谩tica planteada es necesario recalcar la importancia de conocer y entender c贸mo es el desarrollo e implementaci贸n en los procesos de gesti贸n ambiental en las empresas del sector textil en Colombia, partiendo de revisiones bibliogr谩ficas que permitan saber la opini贸n de los diferentes autores y como ha sido el proceso de la contabilidad ambiental en las empresas. Igualmente se utiliz贸 como instrumento para la recolecci贸n de informaci贸n una encuesta, realizada a empresas del sector textil, alimentos, manufacturero, de servicios, entre otros, lo que permiti贸 obtener datos necesarios con el fin de realizar los c谩lculos pertinentes y as铆 determinar cifras reales de las organizaciones que est谩n implementando de la contabilidad ambiental dentro de sus pol铆ticas empresariales

    Introdu莽茫o: Por defini莽茫o, ordem de n茫o reanimar (ONR) consiste 鈥渘a manifesta莽茫o expressa da recusa de reanima莽茫o cardiopulmonar por paciente com doen莽a avan莽ada em progress茫o.鈥 (PUTZEL; HILLESHEIN, BONAMIGO, 2016). Por ser conduta m茅dica, a tomada de decis茫o baseia-se no quadro cl铆nico do paciente, com seu consentimento ou de representante legal, seguindo princ铆pios bio茅ticos. Objetivo: O trabalho objetivou contextualizar a ordem de n茫o reanimar com base nos dispositivos 茅ticos e legais nacionais. Metodologia: Foi realizada revis茫o bibliogr谩fica nas bases de dados Scielo, PubMed e Google Acad锚mico a partir dos descritores 鈥渘茫o reanimar鈥 ou 鈥渇ase terminal鈥 ou 鈥渃onsidera莽玫es 茅ticas鈥 e 鈥減aciente terminal鈥, publicados no per铆odo de 2007 a 2017. Resultados: Foram encontrados 20 artigos e inclu铆dos cinco, al茅m de duas resolu莽玫es. No Brasil, a ONR n茫o possui uma resolu莽茫o vigente, apresentando-se como uma cl谩usula das diretivas antecipadas de vontade, em que o paciente pode manifestar sua vontade em caso de ocorr锚ncia de parada cardiorrespirat贸ria, conforme Resolu莽茫o CFM 1.995/12 (CFM, 2012). De acordo com essa Resolu莽茫o, qualquer pessoa pode elaborar uma Diretiva Antecipada ou pode o m茅dico registrar em prontu谩rio seus desejos. Ressalve-se que essa vontade prevalece sobre qualquer outro parecer n茫o m茅dico, sendo o paciente quem define sobre tratamentos ou cuidados que quer receber, ou n茫o, quando estiver incapacitado de expressar sua vontade (CONSELHO FEDERAL DE MEDICINA, 2012). Tal orienta莽茫o, al茅m de disciplinar a conduta m茅dica, respeita a autonomia e tem como princ铆pio n茫o prolongar o sofrimento de pacientes terminais. Em estudo realizado em servi莽o oncol贸gico, foram entrevistados 104 pacientes e 100 familiares, no ano 2014, e a maioria mostrou-se favor谩vel 脿 ONR para paciente em estado terminal de vida e mostrou prefer锚ncia pela realiza莽茫o da decis茫o compartilhada entre pacientes, familiares e m茅dico (EIDT; BRUNERI; BONAMIGO 2017). Nunes (2009) relata que mesmo na aus锚ncia do consentimento informado, o m茅dico deve envolver o paciente na decis茫o de seu tratamento, bem como esclarecer sobre as circunst芒ncias e as consequ锚ncias que podem advir da sua decis茫o na terminalidade da sua vida. De acordo com a Resolu莽茫o n. 1.805/2006 do Conselho Federal de Medicina, na fase terminal de enfermidades 茅 permitido ao m茅dico limitar procedimentos e tratamentos que prolonguem a vida do doente, garantindo-lhe al铆vio dos sintomas que levem ao sofrimento, assist锚ncia integral, respeitando a vontade do paciente ou de seu representante legal. Segundo o artigo 41, par谩grafo 煤nico do C贸digo de 脡tica M茅dica (CONSELHO FEDERAL DE MEDICINA, 2009), justifica-se a n茫o reanima莽茫o nos casos de doen莽a incur谩vel e terminal, mas o m茅dico deve oferecer cuidados paliativos, levando em considera莽茫o a vontade do paciente ou representante legal (CONSELHO FEDERAL DE MEDICINA, 2009). Conclus茫o: Entende-se que os m茅dicos devem abordar os pacientes em fim de vida sobre a ONR, levando em considera莽茫o sua vontade ou a do representante legal, tratando-o com empatia e respeitando sua decis茫o auton么mica. Al茅m disso, desponta a necessidade de se promover uma melhor qualidade de vida nesse espa莽o de tempo por meio de cuidados paliativos oncol贸gicos. Ademais, o m茅dico est谩 autorizado a moderar os procedimentos em pacientes fora de possibilidades terap锚uticas de cura, evitando uma morte dolorosa e indigna.Palavras-chave: Paciente terminal.

    Targeting the gut microbiota with dietary fibers: a novel approach to prevent the development cardiovascular complications linked to systemic lupus erythematosus in a preclinical study.

    This study is to investigate whether dietary fiber intake prevents vascular and renal damage in a genetic mouse model of systemic lupus erythematosus (SLE), and the contribution of gut microbiota in the protective effects. Female NZBWF1 (SLE) mice were treated with resistant-starch (RS) or inulin-type fructans (ITF). In addition, inoculation of fecal microbiota from these experimental groups to recipient normotensive female C57Bl/6J germ-free (GF) mice was performed. Both fiber treatments, especially RS, prevented the development of hypertension, renal injury, improved the aortic relaxation induced by acetylcholine, and the vascular oxidative stress. RS and ITF treatments increased the proportion of acetate- and butyrate-producing bacteria, respectively, improved colonic inflammation and integrity, endotoxemia, and decreased helper T (Th)17 proportion in mesenteric lymph nodes (MLNs), blood, and aorta in SLE mice. However, disease activity (splenomegaly and anti-ds-DNA) was unaffected by both fibers. T cell priming and Th17 differentiation in MLNs and increased Th17 infiltration was linked to aortic endothelial dysfunction and hypertension after inoculation of fecal microbiota from SLE mice to GF mice, without changes in proteinuria and autoimmunity. All these effects were lower in GF mice after fecal inoculation from fiber-treated SLE mice. In conclusion, these findings support that fiber consumption prevented the development of hypertension by rebalancing of dysfunctional gut-immune system-vascular wall axis in SLE.This work was supported by Grants from Ministry of Science and Innovation of Spain (MCIN) (Ref.

    Brazil has the second-largest dairy cattle herd in the world, and bovine mastitis still can cause significant losses for dairy farmers. Despite this fact, little information is available about milk microbial composition of Brazilian dairy cows, as well as the potential use of bacteriophages in the control of S. aureus. Here, we investigated milk bacterial composition of 28 Holstein Fresian cows (109 teats), selected in the dry-off period, using 16S rRNA analysis. Furthermore, a representative S. aureus strain (UFV2030RH1) was obtained at drying-off for isolation of a bacteriophage (vB_SauM-UFV_DC4, UFV_DC4) and bacterial genomic comparison purposes. Our outcomes revealed that Staphylococcus was the third most prevalent genus and positively correlated with subclinical mastitis events. As a major finding, genomic analyses showed the presence of adhesive matrix molecules that recognize microbial surface components (MSCRAMM) in UFV2030RH1 and might indicate great biofilm formation capability. A minimum inhibitory concentration (MIC) assay showed that resistance to ampicillin was the highest among the antibiotic tested in S. aureus 3059 and UFV2030RH1, displaying values four and sixteen times greater than MIC resistance breakpoint, respectively. Together, our results suggest that Staphylococcus is highly prevalent in dairy cows at drying-off and the use of the phage UFV_DC4 as a biocontrol agent must be investigated in future studies

    Como formador de formadores, debemos hacer que el futuro profesorado tome conciencia sobre la necesidad de conseguir una sociedad inclusiva, innovadora y reflexiva que proporcione a las futuras generaciones una formaci贸n matem谩tica de calidad. La perspectiva de g茅nero resulta un enfoque esencial, cuya incorporaci贸n en los contenidos de investigaci贸n e innovaci贸n se considera elemento fundamental para introducir factores actitudinales, emocionales y formativos. Situamos esta perspectiva en el epicentro, para fomentar la presencia de mujeres en carreras universitarias de Ciencia y Tecnolog铆a. En el trabajo que aqu铆 presentamos se muestran los primeros resultados, tras analizar mediante un instrumento dise帽ado por el grupo de investigaci贸n, distintas unidades did谩cticas, contenidas en libros de textos de secundaria de diversas editoriales, para valorar la potencialidad formativa de las mismas desde una perspectiva de g茅nero. Se pretende averiguar las principales carencias y limitaciones de las unidades analizadas y establecer prioridades y recomendaciones para mejorar la calidad de la Educaci贸n Matem谩tica en nuestro entorno y optimizar el material curricular creado por las editoriales. De forma general, los primeros resultados, muestran que, de acuerdo con la primera categor铆a de an谩lisis, 鈥渋magen de la ciencia鈥, los libros de texto est谩n lejos de mostrar una imagen colaborativa, no estereotipada, profesional, conectada con la vida real y m谩s all谩 de lo emp铆rico; con respecto a la segunda 鈥渃onocimiento de referentes femeninos鈥, no se visibiliza a las mujeres, sus aportaciones y los contextos sociales en los que se crearon. Y por 煤ltimo respecto a la categor铆a de 鈥渓enguaje e imagen no sexista鈥, observamos que no se emplean alternativas al masculino gen茅rico, y que tanto el lenguaje como en la imagen, siguen apareciendo, mayoritariamente, sin cuidar los rasgos sexistas.Universidad de M谩laga.

    Desarrollo sostenible en Paraguay: un enfoque en el potencial de las biorrefiner铆as y las energ铆as renovables

    Get PDF
    In Paraguay, the final energy consumption is unsustainable due to a greater participation of petroleum derivatives (39%) and uncertified biomass (41%) compared to electricity (19%). Paraguay is a net importer of petroleum derivatives, where global concern about the volatility of their cost, added to the environmental damage they generate, compromises the scientific community regarding the technological/economic challenges for the exploitation of renewable resources as a productive platform for the country. The objective of this research is to carry out an analysis on the potential development of biorefineries and renewable energies at the country level. The methodology is based on exploratory/descriptive bibliographic research, based on the SWOT analysis. The results reveal the real situation of Paraguay in terms of its potential for sustainable development, as well as the diagnosis of opportunities in research, development and innovation ("R+D+i") and strategies to mitigate possible risks for the implementation of biorefineries in the medium and long term at the national level.En Paraguay, el consumo final de energ铆a es poco sostenible debido a una mayor participaci贸n de los derivados de petr贸leo (39%) y de biomasa no certificada (41%) respecto a la electricidad (19%). Al ser un pa铆s importador neto de derivados del petr贸leo, la preocupaci贸n sobre la volatilidad del precio de los mismos, sumado al perjuicio ambiental que generan, compromete a la comunidad cient铆fica en cuanto a los desaf铆os y retos tecnol贸gicos/econ贸micos para la explotaci贸n de los recursos renovables como plataforma productiva del pa铆s. El objetivo de esta investigaci贸n es realizar un an谩lisis sobre el potencial desarrollo de las biorrefiner铆as y energ铆as renovables a nivel pa铆s, a partir de una revisi贸n bibliogr谩fica del tipo exploratoria/descriptiva basada en un an谩lisis FODA.

    bicyclogermacrene (35.12%), (E)-caryophyllene (14.19%) and α-copaene (8.19%). The antimicrobial and antileishmanial activities were investigated. The oil showed potent antimicrobial activity against Candida albicans and Rhodococcus equi. The oil also showed significant antileishmanial activity, giving the best results against Leishmania guyanensis. A preliminary cytotoxicity assay for this oil was carried out on hamster and mice (Balb/c) peritoneal macrophages. The results obtained were similar to pentamidine and considered not to be cytotoxic to macrophages.7881Conselho Nacional de Desenvolvimento Cient铆fico e Tecnol贸gico (CNPq)Coordena莽茫o de Aperfei莽oamento de Pessoal de N铆vel Superior (CAPES

    AFLP analysis reveals high genetic diversity but low population structure in Coccidioides posadasiiisolates from Mexico and Argentina

    Get PDF
    BACKGROUND: Coccidioides immitis and C. posadasii cause coccidioidomycosis, a disease that is endemic to North and South America, but for Central America, the incidence of coccidioidomycosis has not been clearly established. Several studies suggest genetic variability in these fungi; however, little definitive information has been discovered about the variability of Coccidioides fungi in Mexico (MX) and Argentina (AR). Thus, the goals for this work were to study 32 Coccidioides spp. isolates from MX and AR, identify the species of these Coccidioides spp. isolates, analyse their phenotypic variability, examine their genetic variability and investigate the Coccidioides reproductive system and its level of genetic differentiation. METHODS: Coccidioides spp. isolates from MX and AR were taxonomically identified by phylogenetic inference analysis using partial sequences of the Ag2/PRA gene and their phenotypic characteristics analysed. The genetic variability, reproductive system and level of differentiation were estimated using AFLP markers. The level of genetic variability was assessed measuring the percentage of polymorphic loci, number of effective allele, expected heterocygosity and Index of Association (I(A)). The degree of genetic differentiation was determined by AMOVA. Genetic similarities among isolates were estimated using Jaccard index. The UPGMA was used to contsruct the corresponding dendrogram. Finally, a network of haplotypes was built to evaluate the genealogical relationships among AFLP haplotypes. RESULTS: All isolates of Coccidioides spp. from MX and AR were identified as C. posadasii. No phenotypic variability was observed among the C. posadasii isolates from MX and AR. Analyses of genetic diversity and population structure were conducted using AFLP markers. Different estimators of genetic variability indicated that the C. posadasii isolates from MX and AR had high genetic variability. Furthermore, AMOVA, dendrogram and haplotype network showed a small genetic differentiation among the C. posadasii populations analysed from MX and AR. Additionally, the I(A) calculated for the isolates suggested that the species has a recombinant reproductive system. CONCLUSIONS: No phenotypic variability was observed among the C. posadasii isolates from MX and AR. The high genetic variability observed in the isolates from MX and AR and the small genetic differentiation observed among the C. posadasii isolates analysed, suggest that this species could be distributed as a single genetic population in Latin America
