Authors: Balk Rodrigo De Souza , Holstein Juliana Martins , Lara Simone , Graup Susane 
Published: September 2018

Introdução: O estresse é uma reação inespecífica do corpo a qualquer demanda, interna ou externa, sendo uma parte normal do funcionamento do corpo. O interesse pelo seu estudo no trabalho se destacou nos últimos anos, principalmente no que se relaciona ao impacto negativo que pode proporcionar na saúde dos empregados e, consequentemente, no funcionamento das organizações. No caso dos agentes comunitários de saúde, considera-se que estes encontram-se em ambientes, condições e pressões maiores. Várias estratégias podem ser usadas para minimizar o estresse, entre elas a atividade física, como o método Pilates. Considerando a lacuna de trabalhos reportando os efeitos do método Pilates sobre o estresse, esse estudo teve como objetivo analisar a influência desse método como estratégia de enfrentamento do estresse em Agentes Comunitários de Saúde. Métodos: Participaram do estudo 6 Agentes Comunitários de Saúde, avaliados com o questionário de LIPP, Escala de Estresse no trabalho e Escala de Estresse percebido e submetidos a intervenção com o Método Pilates por 12 semanas para diminuição do estresse. Resultados: Houve uma diminuição dos níveis de estresse dos participantes, mais evidenciada pelo Questionário de LIPP. Conclusão: O Pilates se demonstrou eficiente na redução da sintomatologia do estresse, sendo recomendada a realização de novos estudos na área.

Published: September 2018

Este estudo verificou a prevalência de quedas e estabeleceu relações entre medo de cair, funcionalidade e estilo de vida de idosos longevos com e sem histórico de quedas. 61 idosos (83,7±6,1 anos) responderam sobre: Estilo de vida FANTÁSTICO, medo de cair (FES) e funcionalidade das Atividades Instrumentais de Vida Diária (AIVD). A prevalência de quedas foi de 34% e não houve diferença das variáveis entre os grupos. Os idosos possuem estilo de vida considerado “muito bom”, bom nível de desempenho de AIVDs e medo de cair compatível a quedas esporádicas. Houve forte correlação entre o estilo de vida e a AIVD, moderada entre FES e estilo de vida e FES e AIVD. As correlações verificadas entre FES, estilo de vida e AIVD sugerem que o estilo de vida e a capacidade para realizar as atividades instrumentais da vida diária associam-se ao menor medo de cair.

Legislação brasileira sobre o patrimônio genético e o conhecimento tradicional associado: muitas dúvidas para os pesquisadores de todas as áreas Brazilian legislation on genetic heritage and associated traditional knowledge: many doubts for researchers from all areas A nova lei 13.123, de 20 de maio de 20151 e seu decreto regulador ( 8772 de 11 de maio de 20162), que dispõe sobre o acesso ao patrimônio genético (PT) da biodiversidade brasileira, proteção e acesso ao conhecimento tradicional associado (CTA) dos povos indígenas, comunidades tradicionais e agricultura familiar, da remessa e envio para o exterior de amostras do patrimônio genético e da exploração econômica do produto acabado ou material reprodutivo, conforme análise realizada por especialistas em direito, fere a Convenção Americana de Direitos Hu­manos, do Protocolo de San Salvador e esta­belece um grave quadro de perda de direitos dos conhecimentos tradicionais associados, não admissível em Estado Democrático de Direito, o qual ruma a favor da progressão das medidas à respeito dos direitos humanos3. Mais grave ainda, é que a men­cionada legislação, que entrará em vigor em novembro de 2018, fere diretamente grupos vulneráveis, aos quais deveria ser dedicada especial proteção3. Somado a isso, está previsto um colapso burocrático na pesquisa, tanto a básica quanto a aplicada, e as que envolvem cooperação internacional, uma vez que torna obrigatório o registro anterior ao seu início, no sistema nacional de gestão do patrimônio genético e do conhecimento tradicional associado (SisGen). Prevê-se que, laboratórios de pesquisa que utilizam coleções biológicas (fungos, bactérias, etc.) deixarão de funcionar pela falta de acesso a cooperação internacional, aliada ao alto custo4.
The Cybernetic Layer of Juri Lotman’s Metalanguage
Authors: Salupere Silvi 
Published: September 2018

Most accounts of Juri Lotman’s legacy note his interest in information theory and cybernetics which is closely tied to his desire to use exact methods in the humanities. However, this connection itself has hardly been studied. This article focuses on a pair of terms with cybernetic origins found throughout Lotman’s works : “mechanism” and “ustrojstvo”. I try to show that these terms and the way they are used are not accidental but belong to an important strand in Lotman’s thought. An overview is presented of Lotman’s direct contacts with cybernetics and cyberneticians, and how the terms “ustrojstvo” and “mechanism” found their way into his metalanguage. The main focus is on exploring how Lotman understands this pair of terms. Translation problems related to them are also discussed.
Flexible and Thermally Stable Optical Polarizers Based on Highly Aligned Carbon Nanotube Sheets for the Visible Spectral Range
Authors: Jung Moonyoung , Noh Youngji , Suh Dongseok , Ahn Seung‐Eon 
Published: September 2018

AbstractDevelopment of new types of optical components applicable to flexible and stretched substrates is essential for designing innovative display platforms for wearable and outdoor applications. Here, a novel polarizer based on highly aligned macroscopic carbon nanotube (CNT) sheets with flexibility, thermal stability, high polarization efficiency, and high transmittance is introduced. Since the conductive multiwalled CNTs are essentially held together by van der Waals forces, wire‐grid‐type polarizers of well‐aligned conductive CNTs in one direction can be developed without complex and difficult manufacturing processes. The CNT sheet exhibits uniform polarization efficiency in the visible light region and maintains its polarization characteristics without physical deformation even at temperatures greater than 100 °C. Moreover, the transmission according to the angle formed by two CNT sheets follows the Malus law, similar to a typical polarizer. Finally, the applicability of the CNT sheet polarizer on a commercial liquid crystal displays monitor is demonstrated.

Published: September 2018

Abstract3D printing of metallic microstructures is highly desirable for many practical applications such as microelectronics, terahertz photonics, microelectromechanical systems, and electrochemisty. Unfortunately, high resolution microprinting of 3D metal structures with widely tunable feature sizes, high conductivities, high melting points, and highly smooth surfaces remains challenging for current microfabrication technologies. Herein, 3D printing of metallic microstructures of feature sizes ranging from ≈10 to ≈200 μm by combining femtosecond laser micromachining of 3D glass microchannels and microfluidic electroless plating is demonstrated. The proposed technique allows for producing 3D metallic structures of almost arbitrary geometries embedded in glass since the continuous flow of the plating solution enables controllable deposition of metal films inside the through microchannels. Moreover, freestanding metallic 3D microstructures are fabricated by removing the glass matrix with a wet chemical etching. As a nonthermal processing, the surface roughness of the fabricated metallic structures is as low as ≈20 nm. The 3D microstructures can be made of either silver or copper covered with a thin layer of silver, which are shown to have a high conductivity. As a proof‐of‐concept demonstration, a 3D metal scaffold structure with a size of ≈5 × 5 × 2 mm3 is printed.

Authors: Glazier Daniel A. , Schroeder John M. , Liu Jitian , Tang Weiping 
Published: September 2018

AbstractWe recently developed a novel chiral catalyst‐directed dynamic kinetic diastereoselective acylation of hemiacetals for the synthesis of carbohydrates. In this update, we describe a catalytic method for the dynamic kinetic enantioselective acylation of 2‐chromanols using benzotetramisole derived catalysts. High yields and enantiomeric excesses were obtained for a broad range of acylated 2‐chromanols, which are important intermediates for the synthesis of various bioactive pharmaceuticals. We hypothesize that the high stereoselectivity of the reaction originates from a novel cation‐n interaction between the chromanol substrate and the acylated catalyst.magnified image
P‐Type SnO Thin Film Phototransistor with Perovskite‐Mediated Photogating

Published: September 2018

AbstractA p‐type phototransistor based on tin monoxide (SnO) thin film and a perovskite‐mediated photogating effect to enhance the device performance are reported. Without the perovskite layer, the SnO thin film phototransistor exhibits a good figure of merit including on/off ratio (Ion/Ioff) over 103, hole mobility of 3.55 cm2 V−1 s−1, photoresponsivity of 1.83 × 103 A W−1, and detectivity of 2.11 × 1013 Jones at 655 nm; these values are among the highest reported for oxide‐based devices. Furthermore, it is shown that when a hybrid perovskite MAPbI3 overlayer is deposited on the p‐type SnO channel, the phototransistor behavior is significantly modified. Specifically, the field‐effect mobility increases to 5.53 cm2 V−1 s−1 and the on/off ratio increases to 2.7 × 103 compared with an on/off ratio of 519 under dark. These effects can be ascribed to a perovskite‐mediated photogating effect with favorable band alignment and interfacial charge transfer. This work not only introduces SnO as a new p‐type phototransistor material but also presents a general approach to enhance the channel transport via coating a photoactive perovskite overlayer.
Boosting Potassium Storage Capacity Based on Stress‐Induced Size‐Dependent Solid‐Solution Behavior

Published: September 2018

AbstractA prerequisite for successful development of a K‐ion battery anode based on solid‐solution behavior is to improve its potassium storage capacity. Increasing the solid‐solution domain by decreasing the particle size offers a promising strategy for enhancing the potassium storage capabilities of insertion anode materials. Extended solid‐solution composition range in nanostructured particles is mainly due to the existence of a coherency strain that suppresses phase separation upon intercalation. Here, the intercalation stress effect in size‐dependent solid‐solution behavior is explored by insertion of K+ into K2Ti6O13 nanowires with different diameters. K2Ti6O13 nanowires with small average diameter of ≈5.5 nm deliver a large initial reversible depotassiated capacity of ≈120 mAh g−1 (deinsertion of ≈2.5 K+) at 0.2 C. The remarkably high reversible depotassiated capacity is mainly ascribed to the decrease of the incoherent interface upon potassiation. The direct observation of enrichment of intragranular particles in potassiated K2Ti6O13 nanowires with average diameter of ≈38 nm provides evidence of strain‐accommodating misfits or dislocations in solid‐solution intercalation compounds. This work offers a promising route to utilize coherency strain energy for K‐ion batteries with improved specific capacity and alleviated irreversible capacity loss.

AbstractLithium‐sulfur (Li‐S) batteries are of considerable research interest for their application potentials in high‐density energy storage. However, the practical application of Li‐S batteries is severely plagued by polysulfide (PS) dissolution and serious safety concerns caused by flammable sulfur and polymer separators. Herein, a nonflammable multifunctional separator for efficient suppression of PS dissolution and high‐temperature performance of Li‐S batteries is reported. Polyacrylonitrile (PAN) and ammonium polyphosphate (APP) are electrospun into a multifunctional separator (PAN@APP) for stable and safe Li‐S batteries. Owing to the abundant amine groups and phosphate radical in APP, the PAN@APP separator has strong binding interactions with PS, which exerts strong charge repulsion to suppress the transport of negatively charged PS ions and free radicals. Furthermore, refractory APP ensures the stability of the battery at high temperatures. Using the PAN@APP separator, the Li‐S battery demonstrates a capacity retention of 83% over 800 cycles. This work provides a robust materials platform for stable and safe Li‐S batteries and points to a direction to close the current gap facing the commercialization of high‐energy next‐generation electrochemical conversion/storage devices.
“Moving from transactional government to enablement” in Indigenous service delivery: The era of New Public Management, service innovation and urban Aboriginal community development
Authors: Howard‐Wagner Deirdre 
Published: September 2018

AbstractOver the last 40 years, Aboriginal Community Based Organisations have played a distinctive role in society in relation to urban Aboriginal peoples and their rights to self‐determination and community development in the Australian city of Newcastle. They have proven essential to advocacy, the maintenance of community development, and the creation of new Aboriginal social infrastructure (community organisations, facilities, services, and supporting infrastructure). Autonomy has been empowering for local Aboriginal people. Major reforms to the delivery of government social services, particularly government enablement of a new social service market based on New Public Management principles, threaten this success. This interpretive, qualitative case study illustrates the effects of social service market enablement. It draws on a case study of the effects of social service market enablement on urban Aboriginal Community Based Organisations in Newcastle, showing the antagonistic relationship between social service market enablement and Aboriginal community enablement and development. It ends with a discussion of how Aboriginal community development in this city could be re‐enabled in light of the Prime Minister's arguments in his 2017 Annual Parliamentary Closing the Gap speech providing particular value in the context of policy discussions about moving from transactional government to enablement in Indigenous affairs.

Published: September 2018

AbstractReported herein is the first isolation of tetracyano‐naphthalenediimide [NDI(CN)4] and its radical anion, and structural elucidation through spectroscopic and X‐ray diffraction studies. The radical anion shows remarkable stability and was purified by chromatography, which is unique for planar radical anions. The stability results from multiple hydrogen bonds to the counter ion and through an array of intramolecular noncovalent interactions. The radical anion revealed one of the strongest NDI π–π interactions (3.268 Å). Electrochemical studies of [NDI(CN)4] confirm its extraordinarily low‐lying LUMO (−5.0 eV), rendering it one of the strongest electron‐deficient planar π systems to be isolated. The manifold potential, which remained unknown to date, can now be explored for these open‐ and closed‐shell planar π systems.

Published: September 2018

Premise of the StudyHigh‐yield pure chloroplast DNA (cpDNA) is necessary for whole genome sequencing. Chloroplast extraction with traditional high‐salt methods causes damage to nuclei and destroys the integrity of organelles, which leads to high genomic contamination from the nucleus and mitochondria. To overcome this issue, we modified a traditional high‐salt method to obtain a new approach called the NaOH low‐salt method (NLS).Methods and ResultsThe NLS method is based on the mild alkaline lysis of plant cells, followed by homogenization with ultrasonic waves and fractionation under reduced osmotic pressure. Results showed that this modified protocol worked efficiently to extract the intact chloroplast from Aeluropus littoralis and other grasses to obtain high‐quality pure cpDNA, which was confirmed by fluorescent microscopy, qPCR, and Illumina paired‐end sequencing analysis.ConclusionsCompared with high‐salt methods, the NLS method has proven robust for extraction of intact chloroplasts and preparation of high‐yield pure cpDNA from grasses.
Comparative binding of kaempferol and kaempferide on inhibiting the aggregate formation of mutant (G85R) SOD1 protein in familial amyotrophic lateral sclerosis: A quantum chemical and molecular mechanics study
Authors: Srinivasan E. , Rajasekaran R. 
Published: September 2018

AbstractMutation in Cu/Zn superoxide dismutase (SOD1) at position 85 from glycine to arginine was found to be a prominent cause of aggregation characterized by an increased content of β‐sheets in familial amyotrophic lateral sclerosis (fALS). Various literatures reported that natural polyphenols could act as a β‐sheet breaker and therefore, treated as a potential therapeutics against various aggregated proteins involved in neurodegenerative disorders. Through computational perspective, molecular docking, quantum chemical studies, and discrete molecular dynamics were implemented to study the binding and structural effect of natural polyphenols, kaempferol, and kaempferide on mutant SOD1. Kaempferol exhibited significant binding and greater residual energy contribution with mutant SOD1 than kaempferide. More interestingly, kaempferol was found to reduce the β‐sheet content augmenting the mutant conformational stability and flexibility relative to that of kaempferide. Hence, the inhibition of mutant SOD1 aggregation by kaempferol was explored, thereby suggesting kaempferol could act as a drug candidate for the design of the natural therapeutics against fALS. © 2018 BioFactors, 44(5):431–442, 2018
SwitCCh: Metal‐Site Design for Controlling the Assembly of a Coiled‐Coil Homodimer
Authors: Aupič Jana , Lapenta Fabio , Jerala Roman 
Published: September 2018

AbstractConformational change of proteins in response to chemical or physical signals is the underlying principle of many regulatory and transport mechanisms in biological systems. The ability to design proteins the conformational state of which can be precisely and reversibly controlled would facilitate the development of molecular machines tailored for specific applications. Here we explore metal‐binding site design to engineer a peptide‐based conformational switch called SwitCCh that assembles into a homodimeric coiled‐coil in response to the addition of ZnII ions or low pH. Addition of ZnII promoted formation of a parallel homodimer with an increase in thermal stability by more than 30 °C. The peptide could be reversibly cycled between the coiled‐coil and random conformation. Furthermore, the SwitCCh peptide was orthogonal to the previously developed coiled‐coil dimer set, indicating it could be used for regulated self‐assembly of coiled‐coil based nanostructures and materials.
Expression of the hormonal FGF co‐receptor Klotho beta in the Xenopus laevis model
Authors: Chen Geng , Tao Qinghua 
Published: September 2018

AbstractKlotho beta (Klb), a single‐pass transmembrane protein, has been described as a co‐receptor for endocrine FGFs, such as FGF15/19 and FGF21, to regulate critical metabolic processes in multiple organs and tissues in adult mice. However, its function during early embryonic development remains largely unknown. In this paper, we evaluated for the first time the expression of klb mRNA during early development of Xenopus laevis by RT‐PCR and whole mount in situ hybridization. RT‐PCR experiments showed that the expression of klb was initially detected at late gastrula stage followed by a quick increasing and continued expression throughout embryonic development. Whole mount in situ hybridization detected specific expression of klb in many primordial organs at tailbud stage such as liver primordium and pancreatic buds, implying that the hormonal FGF signaling may play a role in the foregut development. The dynamic and specific expression patterns of klb also suggest that Xenopus laevis can serve a convenient model for the function of the hormonal FGF signaling in organogenesis and metabolism regulation during embryonic development.

Published: September 2018

AbstractHerein, we report on layer‐by‐layer MnCo2O4/NiMn double hydroxide (LDH) nanosheet arrays (NAs) that are designed and synthesized by in‐situ growing the NiMn LDH NAs onto the surface of the MnCo2O4 NAs. The layer‐by‐layer architecture together with the synergistic effects between the NiMn LDH and MnCo2O4 components, substantially improves the energy storage performance of the composite NAs electrodes. The optimized composite NAs electrode exhibits a high specific capacitance of 3063 F g−1 at 3 A g−1 (four times with respect to the individual MnCo2O4 electrode), a capacitance retention of 2315 F g−1 at 30 A g−1, and a cycle stability with 94.7 % capacitance retention at 20 A g−1 over 5000 cycles. Moreover, an assembled MnCo2O4/NiMn LDH//active carbon (AC) asymmetric solid‐state supercapacitor (ASSC) is found to achieve a high energy density of 51.9 W h kg−1 at 806 W kg−1. These findings might offer a feasible strategy to synthesize the high‐performance MnCo2O4‐based composite electrodes for supercapacitors (SCs).
