Analyzing the production, quality, and potential uses of solid recovered fuel from screening waste of municipal wastewater treatment plants

Over time, wastewater management evolves into a circular model, producing energy and moving towards zero waste. The usual screening waste treatment is the elimination, with no energy recovery processes. As an alternative, the production of solid recovered fuel (SRF) from screening has been studied, both non-densified and densified, in pellet form. The densification was developed, taking as variables the input moisture and size of the die, obtaining 20 different samples. The optimum pelletizing conditions are an input moisture content of 10% and dies with a compression ratio of 6/20, 6/24 and 8/32. SRF properties have been evaluated based on a quality proposal presented in this paper, which has been developed given the lack of uniformity in the existing SRF standards. The SRF produced complies with fuel quality requirements, such as lower calorific value, with values between 13.37 and 25.65 MJ/kg; Cl and Hg content, with maximums of 0.066% and 1.0 × 10����� 5 mg/MJ, respectively; and ash content, between 7.22% and 9.85%. Energy from waste plants could be the destination for all the SRF produced. Its use in cement plants and gasification processes, more restrictive than the previous one, would require manufacturing processes with adequate moisture levels and die size.EMASAGRA 4325University of Granada / CBU

A Novel NFIX-STAT6 Gene Fusion in Solitary Fibrous Tumor: A Case Report

Solitary fibrous tumor is a rare subtype of soft-tissue sarcoma with a wide spectrum of histopathological features and clinical behaviors, ranging from mildly to highly aggressive tumors. The defining genetic driver alteration is the gene fusion NAB2–STAT6, resulting from a paracentric inversion within chromosome 12q, and involving several different exons in each gene. STAT6 (signal transducer and activator of transcription 6) nuclear immunostaining and/or the identification of NAB2–STAT6 gene fusion is required for the diagnostic confirmation of solitary fibrous tumor. In the present study, a new gene fusion consisting of Nuclear Factor I X (NFIX), mapping to 19p13.2 and STAT6, mapping to 12q13.3 was identified by targeted RNA-Seq in a 74-year-old female patient diagnosed with a deep-seated solitary fibrous tumor in the pelvis. Histopathologically, the neoplasm did not display nuclear pleomorphism or tumor necrosis and had a low proliferative index. A total of 378 unique reads spanning the NFIXexon8–STAT6exon2 breakpoint with 55 different start sites were detected in the bioinformatic analysis, which represented 59.5% of the reads intersecting the genomic location on either side of the breakpoint. Targeted RNA-Seq results were validated by RT-PCR/ Sanger sequencing. The identification of a new gene fusion partner for STAT6 in solitary fibrous tumor opens intriguing new hypotheses to refine the role of STAT6 in the sarcomatogenesis of this entity

Reflexiones sobre ‘Occupy. The spatial dynamics of discourse in global protest movements’ de Luisa Martin Rojo

La publicación del libro Occupy. The spatial dynamics of discourse in global protest movements, editado por Luisa Martin Rojo abre un nuevo campo para los estudios del discurso en el que se otorga centralidad al espacio en un sentido dinámico. Por este motivo, como parte del foro e-conversa (promovido por la Asociación Internacional de Estudios sobre Discurso y Sociedad EDiSo; http://www.edisoportal.org/) se planteó la lectura del capítulo introductorio (cuya traducción al español se encuentra en este número de Discurso y Sociedad) y debatir sobre algunas de las cuestiones que en él se plantean. El resultado está formado por varias contribuciones que, tomando como punto de partida el texto de Martín Rojo, reflexionan, entre otros temas, sobre las prácticas espaciales, el papel de los medios de comunicación y las redes sociales, el nuevo sujeto político emergente, las formaciones contrahegemónicas, el multilingüismo, prácticas prefigurativas, etc. De este modo, este texto dialógico es una invitación a seguir pensando el análisis del discurso desde una perspectiva novedosa ligada al espacio / The publication of the volumen Occupy. The spatial dynamics of discourse in global protest movements, edited by Luisa Martín Rojo, opens up a new field of discourse studies in which the focus lies on space, in a dynamic sense. For this reason, and as part of the forum e-conversa (hosted by the International Association of Discourse Studies and Society (EDiSo); http://www.edisoportal.org/Ediso), it was suggested to read the introduction (the Spanish translation of which is included in this issue of Discurso y Sociedad) and to debate over some of the topics presented in the book. The result consists of several contributions which, by taking Martin Rojo’s text as the starting point, reflect on spatial practices, the role of mass media and social networks, the new emerging political subject, counter-hegemonic formations, multilingualism, and prefigurative practices, among other issues. Thus, this dialogic text is an invitation to continue thinking about discourse analysis from a new perspective linked to space

The nutrigenetic influence of the interaction between dietary vitamin E and TXN and COMT gene polymorphisms on waist circumference: a case control study

Journal Article; Research Support, Non-U.S. Gov't;BACKGROUND Abdominal obesity (AO) is a common modifiable risk factor for certain non-communicable diseases associated with enhanced oxidative stress (OS). The objective of this work was to investigate whether the interaction between antioxidant vitamin intake and OS-related polymorphisms modulates gene-associated anthropometry in a Spanish population. METHODS A total of 246 subjects with AO, and 492 age and gender matched non-AO subjects were included in the study. Anthropometric, biochemical, and OS parameters, and antioxidant dietary intake data were assessed using validated procedures. DNA from white blood cells was isolated and the genotype of seven polymorphisms from genes involved in OS (pro-oxidant and antioxidant) were analyzed using the SNPlex system. The effects of the c.-793T > C polymorphism on promoter activity and thus thioredoxin (TXN) activity were examined using reporter assays. RESULTS The AO group had higher 8-Oxo-2'-deoxyguanosine levels and took in less vitamin A and vitamin E compared to the non-AO group. Logistic regression analysis revealed that the rs2301241 polymorphism in TXN and rs740603 in catechol-O-methyltransferase (COMT) were associated with waist circumference (WC) and AO. Moreover, these polymorphisms were more strongly associated with variations in WC in subjects with low vitamin E intakes. A promoter assay revealed that the T to C conversion at c.-793 (rs2301241) induced a more than two fold increase in reporter gene expression. CONCLUSIONS WC is associated both with dietary vitamin E intake and genetic variants of TXN and COMT suggesting that existence of a complex nutrigenetic pathway that involves regulation of AO.This work was co-funded with European Funds for Regional Development (FEDER), the Spanish Science and Technology Ministry [SAF2005-02883]; the health research fund from the Carlos III Health Institute [PI070497], CIBER Fisiopatología Obesidad y Nutrición (CIBERobn) [CB06/03], and CIBER de Diabetes y Enfermedades Metabólicas Relacionadas (CIBERDEM).

Biomaterials from beer manufacture waste for bone growth scaffolds

Agricultural wastes are a source of renewable raw materials (RRM), with structures that can be tailored for the use envisaged. Here, they have proved to be good replacement candidates for use as biomaterials for the growth of osteoblasts in bone replacement therapies. Their preparation is more cost effective than that of materials presently in use with the added bonus of converting a low-cost waste into a value-added product. Due to their origin these solids are ecomaterials. In this study, several techniques, including X-ray diffraction (XRD), chemical analysis, mercury intrusion porosimetry (MIP), scanning electron microscopy (SEM), and bioassays, were used to compare the biocompatibility and cell growth of scaffolds produced from beer bagasse, a waste material from beer production, with a control sample used in bone and dental regenerative processes

Unravelling the Gut Microbiota of Cow’s Milk–Allergic Infants, Their Mothers, and Their Grandmothers

The gut microbiome constitutes a highly complex ecosystem in which bacteria are the most prominent components. Around 70% of primary colonization of the gut microbiota is maternal in origin [1], and the first 1000 days of life are crucial for the development of the intestinal microbiota [2]. Despite its early formation, the gut microbiota is highly dynamic and dependent on host-associated confounding factors such as age, diet, antibiotics, lifestyle, and environmental conditions [3,4]. Alterations in gut microbiota have been described in people with different types of allergy, including cow’s milk allergy (CMA)This work was supported by Instituto de Salud Carlos III (PI17/01087) and Fundación Sociedad Española de Alergia e Inmunología Clínica (FSEAIC_2016).

Synthesis of giant globular multivalent glycofullerenes as potent inhibitors in a model of Ebola virus infection

The use of multivalent carbohydrate compounds to block cell-surface lectin receptors is a promising strategy to inhibit the entry of pathogens into cells and could lead to the discovery of novel antiviral agents. One of the main problems with this approach, however, is that it is difficult to make compounds of an adequate size and multivalency to mimic natural systems such as viruses. Hexakis adducts of [60]fullerene are useful building blocks in this regard because they maintain a globular shape at the same time as allowing control over the size and multivalency. Here we report water-soluble tridecafullerenes decorated with 120 peripheral carbohydrate subunits, so-called ‘superballs’, that can be synthesized efficiently from hexakis adducts of [60]fullerene in one step by using copper-catalysed azide–alkyne cycloaddition click chemistry. Infection assays show that these superballs are potent inhibitors of cell infection by an artificial Ebola virus with half-maximum inhibitory concentrations in the subnanomolar range
