RESUMO

Media can play a key role in shaping public opinion and setting a policy agenda by conveying and influencing public discourse. This article evaluates how the Spanish media has covered the topic of the forest bioeconomy and what kind of discourse it has produced and reproduced around it. For this purpose, we analysed the content of 204 national and regional newspaper articles. The results reveal the scarce penetration of the forest bioeconomy in media and some weaknesses in the narrative production and communicative dimension. The discourse is mainly constructed by governments with a limited presence of multiple stakeholders and an absence of conflict and divergent or alternative views. In addition, the discourse only addresses regional or local problems within the framework of an extended and dominant paradigm of economic growth considering the forest bioeconomy as an opportunity to combat fire, rural abandonment, smallholdings, and poor forest management. We conclude that media is not using its strategic potential and capacity as a public space. To become agents of change, the media should reflect a forest bioeconomy based on successful experiences of innovation and valorization, and adopt a transformative social vision that gives relevance to the interconnection between multiple stakeholders, forest multifunctionality and rural development.

RESUMO

OBJECTIVE: Vitamin D deficiency has been linked to increased risk of multiple sclerosis (MS) and poor outcome. However, the specific role that vitamin D plays in MS still remains unknown. In order to identify potential mechanisms underlying vitamin D effects in MS, we profiled epigenetic changes in vitamin D receptor (VDR) gene to identify genomic regulatory elements relevant to MS pathogenesis. METHODS: Human T cells derived from whole blood by negative selection were isolated in a set of 23 relapsing-remitting MS (RRMS) patients and 12 controls matched by age and gender. DNA methylation levels were assessed by bisulfite cloning sequencing in two regulatory elements of VDR. mRNA levels were measured by RT-qPCR to assess changes in VDR expression between patients and controls. RESULTS: An alternative VDR promoter placed at exon 1c showed increased DNA methylation levels in RRMS patients (median 30.08%, interquartile range 19.2%) compared to controls (18.75%, 9.5%), p-value<0.05. Moreover, a 6.5-fold increase in VDR mRNA levels was found in RRMS patients compared to controls (p-value<0.001). CONCLUSIONS: An alternative promoter of the VDR gene shows altered DNA methylation levels in patients with multiple sclerosis, and it is associated with VDR mRNA upregulation. This locus may represent a candidate regulatory element in the genome relevant to MS pathogenesis.

RESUMO

Objetivo. Evaluar la efectividad y seguridad del fingolimod en la práctica clínica en las regiones de Navarra, Gipuzkoa y La Rioja. Pacientes y métodos. Estudio retrospectivo y multicéntrico de pacientes con esclerosis múltiple recurrente tratados con fingolimod, siguiendo la ficha técnica. Se evaluó la tasa anualizada de brotes (TAB), el porcentaje de pacientes libres de brotes, la discapacidad usando la escala expandida del estado de discapacidad (EDSS) y el porcentaje de pacientes sin lesiones captantes de gadolinio. Resultados. Un total de 113 pacientes fueron tratados con fingolimod: el 6%, naïve, y el 58% y 35%, pacientes tratados previamente con inmunomodulador y natalizumab, respectivamente. El fingolimod disminuyó la TAB tras el primer (67%; 1 a 0,3; p < 0,0001) y segundo (89%; 1 a 0,1; p < 0,0001) año de tratamiento, y aumentó así el porcentaje de pacientes libres de brotes durante el tratamiento. La EDSS basal fue 3 y después del tratamiento con fingolimod fue 2,5 en ambos años. El porcentaje de pacientes sin lesiones captantes de gadolinio tras el primer año de tratamiento fue del 77%. Resultados similares se observaron en los pacientes naïve y en los tratados previamente con inmunomodulador. En los pacientes tratados previamente con natalizumab no se observaron cambios tras el tratamiento. Conclusiones. El uso del fingolimod en la práctica clínica mostró una efectividad similar a la eficacia observada en ensayos clínicos. No hubo cambios en la TAB al cambiar desde natalizumab, y sólo un paciente tras suspender el natalizumab presentó ‘rebrote’. El fingolimod se comporta como un fármaco seguro, con escasos efectos adversos y con un bajo porcentaje de abandonos (AU)


Aim. To evaluate the effectiveness and safety of fingolimod in clinical practice in Navarra, Gipuzkoa and La Rioja regions. Patients and methods. We conducted a retrospective multi-centre study with recurrent multiple sclerosis patients treated with fingolimod, following the product data sheet. The following data were evaluated: annualised relapse rate (ARR), percentage of patients free from relapses, disability using the Expanded Disability Status Scale (EDSS) and the percentage of patients without gadolinium-enhancing lesions. Results. A total of 113 patients were treated with fingolimod: 6% were naïve, and 58% and 35% were patients previously treated with an immunomodulator and natalizumab, respectively. Fingolimod lowered the ARR after the first (67%; 1 to 0.3; p < 0.0001) and second (89%; 1 to 0.1; p < 0.0001) years of treatment, and thus the number of patients free from relapses during the treatment increased. The baseline EDSS was 3 and after treatment with fingolimod was 2.5 in both years. The percentage of patients without gadolinium-enhancing lesions after the first year of treatment was 77%. Similar results were observed in naïve patients and in those previously treated with an immunomodulator. In patients previously treated with natalizumab no changes were observed following the treatment. Conclusions. The use of fingolimod in clinical practice showed an effectiveness similar to that observed in clinical trials. There were no changes in the ARR after changing from natalizumab, and only one patient presented a ‘relapse’ after withdrawal of natalizumab. Fingolimod acts like a safe drug, with scarce side effects and a low percentage of drop-outs (AU)

RESUMO

Covalent mechanochemistry within bulk polymers typically occurs with irreversible deformation of the parent material. Here we show that embedding mechanophores into an elastomeric poly(dimethylsiloxane) (PDMS) network allows for covalent bond activation under macroscopically reversible deformations. Using the colorimetric mechanophore spiropyran, we show that bond activation can be repeated over multiple cycles of tensile elongation with full shape recovery. Further, localized compression can be used to pattern strain-induced chemistry. The platform enables the reversibility of a secondary strain-induced color change to be characterized. We also observe mechanical acceleration of a flex-activated retro-Diels-Alder reaction, allowing a chemical signal to be released in response to a fully reversible deformation.
