Published: May 2021

La tuberculosis constituye un problema mundial de salud pública. En edades pediátricas representa entre el 3% y el 40% del total de la enfermedad. En países con alta incidencia, como Ecuador, la presencia de casos de tuberculosis infantil siempre indica la circulación de Mycobacterium tuberculosis o el contacto con un enfermo no tratado o no diagnosticado. En nuestro país se presenta un alto porcentaje de subdiagnóstico de tuberculosis infantil y una carga menor a la esperada, principalmente en menores de 5 años. La tuberculosis meníngea es la forma más grave de presentación de infección por M. Tuberculosis en la edad pediátrica, ya que ocasiona una gran parte de muertes y discapacidad. El diagnóstico de la meningitis tuberculosa se logra teniendo en cuenta criterios epidemiológicos, estudios de laboratorio en sangre, líquido cefalorraquídeo y neuroimágenes. El tratamiento temprano mejora el pronóstico, pero el problema radica en hacer el diagnóstico temprano, ya que tiene diferentes formas de presentación clínica que van desde síntomas inespecíficos hasta afectación neurológica grave.

Measuring Market Risk of Commercial Banks Implementing VaR with Historical Simulation Approach
Authors: Haq Minhaz-Ul
Published: May 2021

This paper attempts to picture the impact of the market risk of ten commercial banks located in Bangladesh with the help of a non-parametric model known as the Historical Simulation Approach over the course of eight years. These banks' daily stock prices were used as inputs and analyzed in Microsoft Excel by means of Percentile and LN function. The study revealed market risk exposure as third, second-and first-generation banks from the least to the highest. It also pointed out the ups and downs of these banks' share prices in the selected period. Further analysis showed the portfolio VaR estimation for different time intervals.

Human Behavior in Organizations Related to Abraham Maslow's Hierarchy of Needs Theory
Authors: Altymurat Altymurat
Published: May 2021

The use of Abraham Maslow's hierarchy of needs principle in organisations is discussed in this essay. Physiological requirements, comfort needs, the desire to be loved and respected, and the need for self-esteem are also part of the hypothesis. This is what becomes a model on how to act in an organisation such that the organization's success improves in fulfilling the goal and purpose that has been set out to serve others. The company will function at its best when the requirements for confidentiality, convenience, and certainty are met, allowing the process of meeting user knowledge needs to operate smoothly. That almost all, regardless of their degree of need, desires peace, oversight, and consistent employment opportunities.

Published: May 2021

É imprescindível buscar reconstruir nossas representações sobre a Amazônia, se de fato desejamos colocá-la no centro do destino nacional e do equilíbrioclimático global. E isso passa certamente pelo exercício de uma pesquisa social que esteja seriamente comprometida em tentar ouvir os povos que habitam os territórios amazônicos. Reconfigurar nossas representações depende fundamentalmente de nos deixarmos impactar por esses lugares, seus saberes, suas histórias de resistências... é desarmar-se de nosso instrumental teórico forjado “de fora”, abolindo as hierarquias epistemológicas para nutrir-se das categorias e representações das pessoas que comvivem com as Amazônias. Assim sendo, povos e culturas, com suas formas e visões de mundo, produzem manifestações e caminhos de análise múltiplos. Seja no campo da História ou das demais Ciências Sociais, em crescente movimento de ampliar horizontes sobre as Amazônias,intelectuais têm se debruçado em análises sobre relações que permeiam sentidos e ênfases distintas. Em interfaces de tempos e espaços, desde concepções coletivas, comunitárias ou grupais, produzindo e transmitindo e culturas e saberes, em distintas linguagens, materialidades e espiritualidades, sujeitos históricos emergem em narrativas inovadoras sobre a região.
Percepción del uso de los recursos naturales en la comunidad de Altavista, reserva de la biósfera sierra de vallejo, Nayarit
Authors: Triana Abundis Yimeth Zohara , Ramírez Silva Juan Pablo
Published: May 2021

La situación de protección de la naturaleza es alarmante, debido a que el desarrollo de la sociedad desvalora el papel de la naturaleza. México, país megadiverso plantea como una de las principales estrategias de conservación las Áreas Naturales Protegidas (ANP), que deben involucrar a las comunidades que las habitan, a través del manejo de recursos naturales, en función sus propias necesidades y de la conservación. El estado de Nayarit posee gran diversidad biológica, reflejada en las ANP’s existentes, tal es el caso de la Reserva de la Biósfera Sierra de Vallejo (RBSV) (estatal), regida bajo parámetros federales, aunque no recibe la misma atención; carece de la visión que las comunidades tienen al respecto. Esta investigación analiza la percepción de los habitantes de Altavista sobre el uso de recursos naturales, al vivir en una ANP; abordando un enfoque mixto, aplicando encuesta, y observación, para realizar un diagnóstico social-económico-ambiental, que determine la percepción del uso de los recursos naturales, en diferentes sectores de esta comunidad. El 95% de los encuestados no fue consultado para el establecimiento del ANP, no obstante el 86% está de acuerdo con vivir en ella; asimismo la mitad, recibe un beneficio económico por vivir en la ANP principalmente por el pago por servicios ambientales, el principal recurso que se utiliza es la madera (81%) y en menor grado el agua (5%). Así, la percepción de los habitantes debe ser considerada para la mejora de sus condiciones como también en previos procesos de consulta en futuras declaraciones de ANP.
Re-presenting the Black Gamer : a practice-based exploration of the representation of people, bodies and communities of colour in selected video games
Authors:   , Zindela Luyanda
Published: May 2021

This study uses my art practice to explore and critique stereotypical and violent representations of people, bodies and communities of colour in selected video games. I draw from the work of selected artists, Eva and Franco Mattes as well as Joseph Delappe, who use their art practice to address and unsettle stereotypical and violent video game representations. This study also draws from the work of Kishonna L Gray, who centres her critique of stereotypical and violent representations of people of colour in video games around her own experiences as a gamer of colour. Due to my art practice being at the centre of this study, this study thus adopts a practice based research methodology with an emergent design. Literature suggests that despite having evolved significantly due to rapid advances in computer technology, video games are still often sites where well-trodden tropes and stereotypes in the representation of the racialised other continue to be reproduced and reinforced as the ‘norm’ (Sisler 2008, Leonard 2003, Conditt 2015, Gray 2014). People, bodies and communities of colour represented in the selected video games are often reduced through in-game narrative or gameplay to exotic sites for lustful desire, consumption or violent subjugation (Brock 2011, Sisler 2008, Leonard 2003, Conditt 2015, Gray 2014). This study argues that stereotypical portrayals of people, bodies and communities of colour in video games are often informed by dominant social constructions of race and hierarchal racial difference: often presented by their creators as ‘authentic’ virtual recreations of the real world. Racial stereotypes in video games perpetuate the socially constructed myth that hierarchal racial difference is a naturally occurring phenomenon, permanently fixed and imbedded in nature. This study challenges this myth on the premise that race is not naturally fixed but socially constructed. Drawing from the work of the selected artists as well as my own experiences as a black South African artist and gamer, my art practice challenges various visual/audial representations of hierarchal racial difference in the selected video games. My art practice recontextualises these video game representations, re-presenting them through my lens as a black South African gamer. This research resulted in a body of work, exhibited in partial fulfilment of the Master’s Degree in Fine Art.
Mapping gaseous amines, ammonia, and their particulate counterparts in marine atmospheres of China’s marginal seas: Part 1 – Differentiating marine emission from continental transport

Published: May 2021

Abstract. To study sea-derived gaseous amines, ammonia, and primary particulate aminium ions in the marine atmospheres of China's marginal seas, an onboard URG-9000D Ambient Ion Monitor-Ion chromatography (AIM-IC, Thermo Fisher) was set up on the front deck of the R/V Dongfanghong 3 to semi-continuously measure the spatiotemporal variations in the concentrations of atmospheric trimethylamine (TMAgas), dimethylamine (DMAgas), and ammonia (NH3gas) along with their particulate matter (PM2.5) counterparts. In this study, we differentiated marine emissions of the gas species originating from continental transport using data obtained from December 9 to 22, 2019 during the cruise over the Yellow and Bohai Seas, facilitated by additional measurements collected at a coastal site near the Yellow Sea during summer 2019. The data obtained during the cruise and the coastal site demonstrated that the observed TMAgas and protonated trimethylamine (TMAH+) in PM2.5 over the Yellow and Bohai Seas overwhelmingly originated from marine sources. During the cruise, there was no significant correlation (P > 0.05) between the simultaneously measured TMAH+ and TMAgas concentrations. Additionally, the concentrations of TMAH+ in the marine atmosphere varied around 0.28 ± 0.18 μg m−3 (average  ±  standard deviation), with several episodic hourly average values exceeding 1 μg m−3, which were approximately one order of magnitude larger than those of TMAgas (approximately 0.031 ± 0.009 μg m−3). Moreover, there was a significant negative correlation (P < 0.01) between the concentrations of TMAH+ and NH4+ in PM2.5 during the cruise. Therefore, the observed TMAH+ in PM2.5 was overwhelmingly derived from primary sea-spray aerosols. Using the TMAgas and TMAH+ in PM2.5 as tracers for sea-derived basic gases and sea-spray particulate aminium ions, the values of non-sea-derived DMAgas and NH3gas, as well as non-sea-spray particulate DMAH+ in PM2.5, were estimated, and the estimated average values of each species contributed to 16 %, 34 %, and 65 % of the observed average concentrations, respectively. Uncertainties remained in the estimations as TMAH+ may decompose into smaller molecules in seawater to varying extents. The non-sea-derived gases and non-sea-spray particulate DMAH+ likely originated from long-range transport from the upwind continents, according to the recorded offshore winds and increased concentrations of SO42− and NH4+ in PM2.5. The lack of a detectable increase in the particulate DMAH+, NH4+, and SO42− concentrations in several SO2 plumes did not support the secondary formation of particulate DMAH+ in the marine atmosphere.

Atores, ações e dominação cultural na construção da indústria de capital de risco no Brasil
Authors: Mundo Neto Martin , Saltorato Patricia
Published: May 2021

Este artigo aborda a indústria brasileira de capital de risco a partir da trajetória dos agentes que contribuíram para seu desenvolvimento. O Estado desempenhou um papel importante na regulamentação dessa indústria, notadamente a partir da criação da Comissão de Valores Mobiliários (CVM), da Financiadora de Estudos e Projetos (FINEP) e da BNDESPar, subsidiária do Banco Nacional de Desenvolvimento Econômico e Social (BNDES). O artigo conclui que, apesar da legitimidade desta indústria estar ligada ao financiamento da inovação tecnológica pelas firmas gestoras que atuam junto ao segmento venture capital, aqueles que dominam culturalmente a indústria, preferem investir no segmento private equity, onde o retorno sobre o investimento é significativamente maior e o risco, menor. Como resultado, os dados extraídos da CVM, indicam que, o financiamento via venture capital, onde a incerteza e os riscos são mais elevados, recaem principalmente sobre as agências governamentais, reproduzindo a dominação cultural predominante na indústria mundial.
A celebrização como sucessora do carisma ou como contrapartida secular? O papel dos famosos na sociedade contemporânea
Authors: Kamradt João
Published: May 2021

Este artigo busca compreender qual o papel do carisma na sociedade contemporânea e qual sua relação com as celebridades – indivíduos que atualmente são responsáveis por concentrar a atenção da sociedade. O carisma, na concepção weberiana, é entendido como uma qualidade de poucos indivíduos, vista como algo mágico, extracotidiano, responsável por dar legitimidade ao líder. A celebridade é um sujeito que ascendeu ao estrelato sem, necessariamente, ter nenhuma qualidade que não seja a de ser conhecido por um grande número de pessoas. Com o declínio das religiões e a diminuição da importância dada aos líderes políticos/religiosos, viso compreender se e até que ponto as celebridades incorporaram elementos típicos da conduta dos líderes carismáticos, se as celebridades são uma forma moderna de carisma, se o carisma weberiano é um conceito datado, não servindo para analisar o atual tempo, ou se continua tendo seu espaço na atual conjectura.

Published: May 2021

O agronegócio se organiza em redes de políticas. Orquestrações das associações de interesses são importantes para revelar o campo da governança política agroindustrial que cresceu com as políticas agrícolas em nível corporativista no Brasil, isto é, sob a regulação estatal da agricultura brasileira nos anos 1960 e 1970, e que se transformaram em governanças mais plurais ou em redes coordenadas e orientadas por negócio, por produto agrícola ou setor agroindustrial. O presente artigo mostra, por meio dos estudos dos casos agroindustriais citrícola e sucroalcooleiro no estado de São Paulo no período 1964/2010, as transformações mais importantes nas duas redes de políticas mais importantes do agronegócio paulista, a partir do campo teórico do neoinstitucionalismo político.
Crime ou desordem de acumulação de animais? O papel das redes sociais no entendimento dos acontecimentos de Santo Tirso

Published: May 2021

Na madrugada de 19 de Julho (2020). em Santo Tirso (Portugal), um fogo florestal atingiu dois abrigos ilegais para animais de companhia. Meia centena morreu. Foram resgatados com vida 110 nào-humanos. As informações veiculadas pelos media indicam a possibilidade de estarmos perante um caso de acumulação de animais. Tendo por base as publicações de Facebook relacionadas com o incidente de duas das maiores organizações portuguesas defensoras da causa animal, procurámos perceber como é que as mesmas e os seus seguidores reagiram ao acontecimento. A análise foi feita com base na técnica de análise de contéudo. Os resultados sugerem que tanto as organizações em causa como os seus seguidores percepcionaram o acontecimento como um acto criminoso. Apesar das informações disponíveis, a possibilidade de estarmos perante a “desordem de acumulação de animais” nunca foi mencionada nas publicações dos murais analisados e surge apenas tuna vez no comentário de um dos seus seguidores.

Kegiatan pelatihan diversifikasi produk olahan jagung manis telah dilaksanakan di Kelurahan Kalampangan Kota Palangka Raya. Keberhasilan pertanian lahan gambut Desa Kalampangan, salah satunya ditunjang oleh sektor hortikultura. Umumnya pemenuhan kebutuhan sayuran sekitar Kota Palangka Raya dipasok dari Desa Kalampangan. Desa Kalampangan merupakan sentral produksi jagung manis di wilayah Kota Palangka Raya. Luas areal penanaman jagung manis menempati urutan teratas yaitu seluas 205 ha dengan produksi sebesar 215 ton/ha. Produksi ini sesuai dengan deskripsi varietas jagung manis dataran rendah  Kegiatan pengabdian ini telah dilaksanakan pada bulan September sampai Oktober 2019 dengan kelompok sasaran ibu - ibu petani Desa Kalamapnagan. Metode kegiatan meliputi : 1) Sosialisasi dan Penyuluhan, 2) Pelatihan dan demontrasi, 3) Pembinaan/ pendampingan, 4) Monitoring.  Tujuan dari kegiatan pelatihan diversifikasi produk olahan jagung manis. berupa puding dan kue talam diharapkan menjadi rintisan wirausaha bagi ibu - ibu petani Desa Kalampangan, adapun untuk pengolahan produk makanan ini hanya perlu teknologi yang sederhana. Sedangkan kontribusi yang diberikan kepada ibu – ibu petani mitra adalah dengan pelatihan pembuatan dua produk makanan yang terbuat dari jagung manis (puding dan kue talam jagung manis), diharapkan menjadi rintisan wirausaha baru skala home industri sehingga dapat menambah pendapatan income keluarga sekaligus untuk  konsumsi sendiri guna memenuhi gizi keluarga.   Dari kegiatan pelatihan ini diharapkan dapat menjaga kestabilan harga  jagung manis di tingkat petani serta ada nilai tambah dari hasil produk olahan jagung manis.

Published: May 2021

O presente artigo tem como objetivo discutir o fenômeno do tráfico de mulheres da região de Kachin, no Mianmar, para a China, através da fronteira terrestre com a província chinesa de Yunnan. Para tanto, utiliza-se dos três níveis de análise explorados pelas teorias de migração: o macro/estrutural, o meso/de redes e sistemas, e o micro/individual. A hipótese central é que as variáveis macro e meso são mais determinantes para a ocorrência do processo em questão. Conclui-se que a existência de um padrão específico de emigrantes não se traduz na escolha racional de migração, haja vista a interferência de fatores macro e meso no fluxo de informações necessário para o cumprimento do processo.
Single-institution retrospective review of elective and emergency embolization of renal angiomyolipoma
Authors: Chapman David , Tyson Matt , Buckley Brendan
Published: May 2021

Introduction: We aimed to evaluate the size reduction and complications after transcatheter embolization of renal angiomyolipomas (AMLs).

Methods: Cases from a single tertiary center were analyzed retrospectively. A blinded radiologist provided measurements of AMLs using a combination of ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). Electronic clinical notes, radiographic imaging, and laboratory data were reviewed.

Results: Twenty-one embolization procedures from 2002–2019 were analyzed. Four cases were emergency, the remainder elective. The average followup time after intervention was 42 months. Techniques included ethanol, PVA, Gelfoam, Embospheres®, Histacryl®, and coils. The median diameter size of AMLs was 8.6 cm pre-procedure and 6.0 cm post-procedure. The median volume of AMLs was 200 cc pre-procedure and 67 cc post-procedure, with a median reduction in volume of 55%. One case (4.8%) had a re-embolization and three cases (14.3%) proceeded with surgical management of the AML. No cases re-presented with bleeding. Post-embolization syndrome is common. Renal arterial dissection and renal abscess are infrequent complications (9% and 4.5%, respectively). There was no treatment-based mortality.

Conclusions: Embolization for renal AMLs is an established, safe, and effective method of treatment and our series further supports that. Determining when to intervene and how long to follow up patients is an issue that has not been well-described; more research needs to be done in this area.

O presente artigo propõe uma metodologia de priorização dos principais incidentes atendidos pelo departamento de Tecnologia da Informação (TI) de uma universidade pública. Para isso, utilizou-se as recomendações da Biblioteca Information Technology Infrastructure Library (ITIL®), para identificação e categorização dos principais incidentes, e, posteriormente, o método Analytic Network Process (ANP), por meio do software SuperDecisions, a fim de determinar um ranking de prioridade nos atendimentos a tais incidentes, nos diferentes cenários analisados. Além disso, visando reduzir o número de cenários, compactando cenários similares em apenas um único cenário, através da teoria da compatibilidade, os vetores de decisão obtidos para tais cenários foram avaliados. Os resultados sugeriram, ao departamento de TI, diferentes formas de atuações, de acordo com os rankings gerados para cada cenário, e uma impossibilidade na generalização entre os cenários relacionados às visitas.

Tendo em vista que o OSSP é NP-hard, uma meta heurística híbrida busca tabu/iterated local search (ILS) é proposta. Foram realizados testes computacionais em 140 instâncias disponíveis na literatura. Foram avaliadas as regras de prioridade LPT, SPT, LAPT e LTRPOM como algoritmos para construção de uma solução inicial. A função objetivo utilizada foi a minimização do makespan e o desvio percentual relativo foi a medida de desempenho adotada. Os resultados computacionais apontam para a competitividade da meta-heurística proposta nas instâncias avaliadas.
Kartellrechts-Compliance für Manager
Authors: Chorongiewski Natascha
Published: May 2021

Antitrust law has become increasingly controversial and relevant in recent decades. This study examines the cases in which managers can be held liable for antitrust violations and compliance failures.

To this end, the author first analyses fundamentally in which cases a compliance obligation exists and from what it can be derived, and then focuses on antitrust violations and, in particular, cases in which manager liability can be considered. In doing so, it also includes criminal liability and a mitigation of liability in accordance with a so-called compliance defence. A comparative analysis of different jurisdictions concludes the work.
Revision of the genus Miridiba Reitter, 1902 (Coleoptera, Scarabaeidae, Melolonthinae): genital morphotypes and new taxonomic data
Authors: Gao Chuan-bu , Coca-Abia María Milagro
Published: May 2021

The genus Miridiba Reitter, 1902, of phytophagous chafers from Asia, is revised based on external morphological and genital (male and female) characters. In this study, a total fifty-eight species of Miridiba were examined, and the genus is redescribed. Male genital characters of Miridiba, especially the morphology of parameres and endophallus, are studied in depth herein. The female genitalia of Miridiba are studied and described in detail for the first time. According to genital characters, nine genital morphotypes, including fifty-four species, are established under the genus Miridiba. Sixty-seven type specimens are studied. Miridiba gressitti (Frey, 1970) comb. nov., Miridiba borneensis (Moser, 1918) comb. nov., Miridiba coxalis (Arrow, 1944) comb. nov., Miridiba rugaticollis (Moser, 1913) comb. nov., Miridiba nigrescens (Moser, 1916) comb. nov., Miridiba scutata (Reitter, 1902) comb. nov., Miridiba ciliatipennis (Moser, 1903) comb. nov. and Miridiba brunneipennis (Moser, 1916) comb. nov. are transferred from Holotrichia. Holotrichia dalatensis Frey, 1970 is transferred to Miridiba as a synonym of Miridiba sinensis (Hope, 1842). Four junior subjective synonyms are proposed: Miridiba pilosella (Moser, 1908) (= Holotrichia formosana Moser, 1909), Miridiba sinensis (= Holotrichia dalatensis Frey, 1970), Miridiba scutata (= Holotrichia scutulata Dalla Torre, 1912 and Miridiba lassallei Keith, 2010). Miridiba frontalis (Fairmaire, 1886) is resurrected as a valid species. A key to 51 of the 58 valid species of Miridiba is presented.
Creative economy: Exploring the concept and European perspective
Authors: Đorić Žarko
Published: May 2021

In recent times, our environment and the way we produce and consume cultural goods and services are changing radically due to the strong influence of globalization, faster communication channels, global connectivity and the implementation of new information and communication technologies. In the conditions of convergence of economic, social, cultural and technological changes, the importance of strengthening creative potentials and capacities to achieve economic and other gains is very much recognized, so new development strategies are needed in this area. In such circumstances, the concept of "creative and cultural economy" is popularized worldwide as the interface between culture, economics and technology. Our world is increasingly dominated by images, sounds, symbols and ideas that create new jobs, wealth and new culture. Because of this, economic development can no longer be considered unilaterally, only through the accumulation of economic capital, but as a three-dimensional space whose dimensions are the size, structure, and the change in the relationship between economic and creative resources. In this paper, the author deals with theoretical and applied aspects of the creative economy development. The obtained results indicate a significant economic potential that the creative economy brings within the European Union, primarily in terms of employment and contribution of enterprises within the creative sector. The research aims to interpret data, describe facts, processes, and objects and empirically confirm their connections and relationships using a descriptive method and a compilation method.
Practice-led Research in the Art Museum
Authors: Engen Line
Published: May 2021

As art museum education practices get more ambitious in form and content, and to a higher degree inform the overall audience strategies, the need for a research framing is required. The art museum is facing new and high expectation from society and policy makers in terms of being a relevant social and democratic platform inclusive for everyone. To manifest the changes, the institution must draw on all the different museal knowledges, not least the one about the audience. There has been a history of professional hierarchy and knowledge hegemony inside the art museum, where the object-based knowledge has trumped the practice-based. An important reason for this imbalance has been the lack of adequate practice related research methods and a theoretical framing within art museum education. Research in art museum has to a large extent operated within the classical art historical field, but more and more museums are looking to and are drawing on other models outside the museum disciplines to develop new adequate research standards. One of the museums that have undergone a profound change much due to a change in how they think about practice and research, is Tate with research leader Emily Pringle in the lead. Inspired by models within the arts and school system, they have developed a practice-led research method. In this article I will reflect on how and why it is important for art museum educators to do research on their own practice, drawing on both the Tate model and my own experience from working at the National Museum for over ten years.
Testing the effectiveness of the forest integrity assessment: A field‐based tool for estimating the condition of tropical forest

Published: May 2021

Global targets to halt biodiversity losses and mitigate climate change will require protecting rainforest beyond current protected area networks, necessitating responsible forest stewardship from a diverse range of companies, communities and private individuals. Robust assessments of forest condition are critical for successful forest management, but many existing techniques are highly technical, time‐consuming, expensive or require specialist knowledge.

To make assessment of tropical forests accessible to a wide range of actors, many of whom may be limited by resources or expertise, the High Conservation Value Resource Network (HCVRN), with the SE Asia Rainforest Research Partnership (SEARRP), developed a South East Asian version of the Forest Integrity Assessment (FIA) tool as a rapid (< 1 hour) method of assessing forest condition in the field, where non‐experts respond to 50 questions about characteristics of the local environment while walking a site transect. Here, we examined the effectiveness of this survey tool by conducting ∼ 1000 assessments of forest condition at 16 tropical rainforest sites with varying levels of disturbance in Sabah, Malaysian Borneo.

We found good agreement (R‐squared range: 0.50–0.78) between FIA survey scores and independent measures of forest condition, including biodiversity, vegetation structure, aboveground carbon and other key metrics of ecosystem function, indicating that the tool performed well. Although there was variation among assessor responses when surveying the same forest sites, assessors were consistent in their ranking of those sites, and prior forest knowledge had a minimal effect on the FIA scores. Revisions or further training for questions where assessors disagree, for example, on the presence of fauna at a site, could improve consistency.

We conclude that the FIA survey tool is a robust method of assessing forest condition, providing a rapid and accessible means of forest conservation assessment. The FIA tool could be incorporated into management practices in a wide range of forest conservation schemes, from sustainability standards, to community forestry and restoration initiatives. The tool will enable more organizations and individuals to understand the conservation value of the forests they manage and to identify areas for targeted improvements.

Identifying miRNAs in multiple sclerosis gray matter lesions that correlate with atrophy measures
Authors: Tripathi Ajai , Pandit Ishani , Perles Aaron , Zhou Yadi , Cheng Feixiong , Dutta Ranjan
Published: May 2021

Objective

Multiple sclerosis (MS) is an inflammatory, demyelinating and neurodegenerative disease of the central nervous system (CNS). Though MS was initially considered to be a white matter demyelinating disease, myelin loss in cortical gray matter has been reported in all disease stages. We previously identified microRNAs (miRNAs) in white matter lesions (WMLs) that are detected in serum from MS patients. However, miRNA expression profiles in gray matter lesions (GMLs) from progressive MS brains are understudied.

Methods

We used a combination of global miRNAs and gene expression profiling of GMLs and independent validation using real‐time quantitative polymerase chain reaction (RT‐qPCR), immuno‐in situ hybridization, and immunohistochemistry.

Results

Compared to matched myelinated gray matter (GM) regions, we identified 82 miRNAs in GMLs, of which 10 were significantly upregulated and 17 were significantly downregulated. Among these 82 miRNAs, 13 were also detected in serum and importantly were associated with brain atrophy in MS patients. The predicted target mRNAs of these miRNAs belonged to pathways associated with axonal guidance, TGF‐β signaling, and FOXO signaling. Further, using state‐of‐the‐art human protein–protein interactome network analysis, we mapped the four key GM atrophy‐associated miRNAs (hsa‐miR‐149*, hsa‐miR‐20a, hsa‐miR‐29c, and hsa‐miR‐25) to their target mRNAs that were also changed in GMLs.

Interpretation

Our study identifies miRNAs altered in GMLs in progressive MS brains that correlate with atrophy measures. As these miRNAs were also detected in sera of MS patients, these could act as markers of GML demyelination in MS.

Conventional self‐charging systems are generally complicated and highly reliant on the availability of energy sources. Herein, a chemically self‐charging, flexible solid‐state zinc ion battery (ssZIB) based on a vanadium dioxide (VO2) cathode and a polyacrylamide‐chitin nanofiber (PAM‐ChNF) hydrogel electrolyte is developed. With a power density of 139.0 W kg‐1, the ssZIBs can deliver a high energy density of 231.9 Wh kg‐1. The superior electrochemical performance of the ssZIBs is attributed to the robust tunnel structure of the VO2 cathode and the entangled network of PAM‐ChNF electrolyte, which provide efficient pathways for ion diffusion. Impressively, the designed ssZIBs can be chemically self‐charged by the redox reaction between the cathode and oxygen in ambient conditions. After oxidation for 6 h in air, the ssZIBs manifest a high discharging capacity of 263.9 mAh g‐1 at 0.2 A g‐1, showing excellent self‐rechargeability. With the assistance of a small amount of acetic acid added to the hydrogel electrolyte, the galvanostatic discharging and chemical self‐charging cycles can reach 20. More importantly, such ssZIBs are able to operate well at chemical or/and galvanostatic charging hybrid modes, demonstrating superior reusability. This work brings a new prospect for designing flexible chemically self‐charging ssZIBs for portable self‐powered systems.
Enhancing Electrochemical CO2 Reduction using Ce(Mn,Fe)O2 with La(Sr)Cr(Mn)O3 Cathode for High‐Temperature Solid Oxide Electrolysis Cells

Published: May 2021

Robust oxide electrodes with high activity and durability have attracted significant attention as alternatives for Ni‐based cathodes in high‐temperature solid oxide electrolysis cells (SOECs). Noncoking La(Sr)Cr(Mn)O3 (LSCM)‐based oxide cathodes have shown promise as durable ceramic cathodes; however, they suffer from low electrocatalytic activities in electrochemical CO2 reduction. In this study, a dual‐phase composite electrode consisting of LSCM and Ce(Mn, Fe)O2 (CMF) is developed to enhance the electrocatalytic activity of CO2 reduction in SOECs. The developed electrode shows excellent electrolysis performance of 2.64 and 1.22 A cm–2 at 1123 K, when voltages of 1.5 and 1.2 V are applied, respectively, without using any precious metal catalysts. The enhanced electrolysis performance is attributed to increases in electrocatalytic activity and surface oxygen vacancies caused by the CMF, which accelerates CO2 adsorption and results in the subsequent dissociation of the carbonate intermediate in the CO2 reduction.

The Nb doping of Li[Ni0.855Co0.13Al0.015]O2 (NCA85) modifies its primary particle morphology to allow precise tailoring of its microstructure. The Nb dopant (1 mol%) elongates the primary particles and aligns them in the radial direction, creating a configuration that effectively dissipates the abrupt internal strain caused by H2↔H3 phase transitions near the charge end. The negation of the internal strain substantially improves the long‐term cycling stability achieved by the Nb‐doped NCA85 cathode; it retains 90% of its initial capacity after 1000 cycles while an undoped cathode retains 57.3%. Moreover, the enhanced mechano‐chemical stability of the Nb‐doped NCA85 cathode enables fast charging; accordingly, the Nb‐doped NCA85 cathode cycles stably for 500 cycles even when charged at 3 C (full charge is achieved in 20 min). The Nb‐doped cathode also demonstrates enhanced chemical and structural stability during calendar aging and under thermal load. The simple strategy of introducing Nb ions during the lithiation of NCA85, proposed in this paper, represents an effective solution that guarantees sufficient battery life, fast charging, and safety without compromising battery capacity for next‐generation electric vehicles.

Objective

Attentional deficits following degeneration of brain cholinergic systems contribute to gait–balance deficits in Parkinson disease (PD). As a step toward assessing whether α4β2* nicotinic acetylcholine receptor (nAChR) stimulation improves gait–balance function, we assessed target engagement of the α4β2* nAChR partial agonist varenicline.

Methods

Nondemented PD participants with cholinergic deficits were identified with [18F]fluoroethoxybenzovesamicol positron emission tomography (PET). α4β2* nAChR occupancy after subacute oral varenicline treatment was measured with [18F]flubatine PET. With a dose selected from the nAChR occupancy experiment, varenicline effects on gait, balance, and cognition were assessed in a double‐masked placebo‐controlled crossover study. Primary endpoints were normal pace gait speed and a measure of postural stability.

Results

Varenicline doses (0.25mg per day, 0.25mg twice daily [b.i.d.], 0.5mg b.i.d., and 1.0mg b.i.d.) produced 60 to 70% receptor occupancy. We selected 0.5mg orally b.i.d for the crossover study. Thirty‐three participants completed the crossover study with excellent tolerability. Varenicline had no significant impact on the postural stability measure and caused slower normal pace gait speed. Varenicline narrowed the difference in normal pace gait speed between dual task and no dual task gait conditions, reduced dual task cost, and improved sustained attention test performance. We obtained identical conclusions in 28 participants with treatment compliance confirmed by plasma varenicline measurements.

Interpretation

Varenicline occupied α4β2* nicotinic acetylcholine receptors, was tolerated well, enhanced attention, and altered gait performance. These results are consistent with target engagement. α4β2* agonists may be worth further evaluation for mitigation of gait and balance disorders in PD. ANN NEUROL 2021;90:130–142
