Authors: Godse Kiran , Godse Gauri , Patil Anant
Published: May 2021

Symptomatic dermographism, a type of physical urticaria is a common condition affecting patient’s quality of life. For its diagnosis, clinicians in India currently use tip of the ball point pen for estimating the provocation threshold. However, because of single tip of fixed length, ball point pen can-not differentiate between different grades of symptomatic dermographism. With variations in the intensity of stroke, there is a possibility of even missing the diagnosis. Hence, there is a need of a better method to diagnose symptomatic dermographism and determine the provocation threshold. Skin writometer, a plastic instrument with three arms of varying length can be novel in this regards. This instrument is simple, user friendly, easy to use and inexpensive. It can be used for diagnosis as well as assessment of treatment response in patients with symptomatic dermographism.

A Multilabel Classifier for Text Classification and Enhanced BERT System
Authors: Bhamare Bhavana R. , Prabhu Jeyanthi
Published: May 2021

Now-a-day, a vast variety of reviews are published on the web. As a result, an automated system to analyze and extract knowledge from such textual data is needed. Sentiment analysis is a well-known sub-area in Natural Language Processing (NLP). In earlier research, sentiments were determined without considering the aspects specified in a review instance. Aspect-based sentiment analysis (ABSA) has caught the attention of researchers. Many existing systems consider ABSA as a single label classification problem. This drawback is handled in this study by proposing three approaches that use multilabel classifiers for classification. In the first approach, the performance of a model with hybrid features is analyzed using the multilabel classifier. The hybrid feature set includes word dependency rule-based features and unigram features selected using the proposed two-phase weighted correlation feature selection (WCFS) approach. In the second and third approaches Bidirectional Encoder Representation from Transformers (BERT) language model is used. In the second approach, a BERT system is enhanced by applying max pooling on target terms which specify an aspect of a review instance and a multibit label is given as input to the BERT system. In the third approach, the basic BERT system is used for word embedding only and classification is done using multilabel classifiers. In all approaches, the label used for all training instances specifies aspects with its sentiments. The experimentation shows that the results gained using the system proposed in the first approach are comparable to the results gained using the BERT system. The experimental results depict that the Enhanced BERT system gives better results compared to the existing systems.
The determinants of Covid-19 mortality rates across Europe
Authors: Psycharis Yannis , Tsimbos Cleon , Verropoulou Georgia , Doukissas Leonidas
Published: May 2021

The aim of this paper is to examine empirically the impact of the demographic structure and socio-economic environment on the Covid-19 mortality rate across 29 European countries. The analysis is based on empirical data recorded cumulatively from the start of the Covid-19 disease until 26th May 2020 covering ‘the first wave of the pandemic’. Results indicate that, although countries with a higher degree of ageing structure are anticipated to be more vulnerable to Covid-19, this study provides evidence that population ageing contributes only marginally to Covid-19 death rates across Europe. Urbanization, the level of economic development and health care systems, seem to better explain patterns of interstate mortality rates. The analysis provides important policy implications since it underlines the importance of urbanization and socio-economic conditions in the accelerating incidence of casualties and signifies the importance of health care systems for the protection of people and places from the pandemic.

Authors: Pinto Vânia , Alves Vandressa , Amorin Sandra , Santos Gustavo , Deon Vinicius
Published: May 2021

O emprego de amidos não convencionais em alimentos e embalagens biodegradáveis, bem como modificações físicas, química ou enzimáticas, possibilitam ampliar as aplicações do amido e agregar valor às matérias-primas. Assim, objetivou-se avaliar o efeito da pré-hidrólise com a enzima α-amilase, na produção de amido ácido-tratados ou amidos hidrolisados, avaliando-se a cinética da hidrólise ácida, o rendimento do processo e a estrutura molecular dos amidos de pinhão e feijão carioca. O percentual da pré-hidrólise com α- amilase foi 7% e 3% para o amido de pinhão e feijão, respectivamente. A cinética de hidrólise ácida com H2SO4 foi maior no amido de pinhão que no de feijão e a pré-hidrólise teve leve efeito em ambos os amidos. O modelo linear apresentou 2 etapas na hidrólise ácida, sendo a primeira fase mais rápida e sensível à pré-hidrolise enzimática. O rendimento da hidrólise foi superior no amido de feijão e a pré-hidrólise aumentou o rendimento no amido de pinhão ácido-tratado somente após 5 dias. A pré-hidrólise enzimática promoveu alterações na estrutura molecular dos amidos, porém após a hidrólise ácida, o efeito predominante foi o do ácido sulfúrico. A ordem molecular de curto alcance específico se perdeu e a proporção de 1047/1022 cm-1 e 1022/995 cm−1 reduziram com a hidrólise ácida. O amido de feijão carioca se mostrou promissor para a produção de amido ácido-tratado, principalmente pelo elevado rendimento (>35%), sendo 180% maior do que o verificado na literatura com a mesma metodologia.

Published: May 2021

Apesar do alto valor nutricional e potencial econômico, muitas espécies nativas e exóticas brasileiras permanecem inexploradas. No Planalto Norte Catarinense, diversas espécies de flora nativa ainda não foram estudadas, dentre elas está o anil (Coccocypselum geophiloides). Assim, este trabalho visou caracterizar o anil quanto a sua composição química e potencial antioxidante. As amostras parcialmente secas foram avaliadas quanto a sua composição química (umidade, cinzas, proteínas, lipídeos, fibra alimentar e suas frações solúvel e insolúvel) e potencial antioxidante (teor de polifenóis e capacidade antioxidante). Dentre os resultados obtidos têm-se destaque para a fibra alimentar a qual representa 64,48% da composição química do anil. Este componente possui elevada relevância funcional e nutricional devido ao papel que desempenha no organismo humano. O teor de polifenóis e a elevada capacidade antioxidante do anil também merecem destaque, principalmente por não terem sido influenciados pelo processo de secagem. Na literatura não existem estudos já publicados sobre o anil, dessa forma todos os resultados obtidos neste trabalho são inéditos. Baseado na sua composição química e propriedade antioxidante, o anil apresenta potencial para ser utilizado em formulações alimentícias, seja por conferir propriedades nutricionais ou funcionais. No entanto, estudos fitotécnicos, toxicológicos, bromatológicos e sobre a aplicação do anil em formulações alimentícias precisam ser conduzidos. Estes resultados poderão estimular o plantio comercial desta espécie nativa e sua inserção no agronegócio local, como uma nova fonte de renda e emprego na região.

Published: May 2021

A indústria de alimentos sofre elevadas perdas com a frutas e hortaliças ao longo de toda cadeia produtiva, tal fato a instiga a buscar alternativas como o desenvolvimento de filmes para revestir alimentos e prolongar sua vida de prateleira. Se faz necessário um estudo principalmente das propriedades mecânicas e de barreira dos filmes, as quais comprovem a eficiência de sua aplicação. Portanto, objetivou-se neste trabalho foi elaborar um filme com base de gelatina extraída da pele de tilápia do Nilo e adição de surfactantes como o Tween 80 e o dodecil sulfato de sódio (SDS) para investigação dessas propriedades. Encontrou-se valores de resistência a tração, módulo de Young e elongação de 3,49 a 38,78 MPa; 1,97 a 14,16 MPa; e 16,40 a 120,49%, respectivamente. Quanto a propriedade de barreira de permeabilidade a vapor de água encontrou-se faixa de baixo valor de 5,90 a 10,12 g.mm.h-1.m2.kPa-1. A espessura  variou conforme a adição de surfactante, sendo de 0,10 a 0,25 mm. O tratamento com a menor concentração de surfactante (SDS e Tween 80) foi o mais eficiente, pois apresentou as melhores propriedades de barreira e foi o menos espesso, o que o classifica como sendo uma boa opção para ser utilizado como uma embalagem com intuito de revestir alimentos para sua preservação.

Authors: Carneiro de Souza Luanna , Mayara Elita Carneiro  , Agnes de Paula Scheer  , Luana Carolina Bosmuler Züge
Published: May 2021

Os óleos essenciais são compostos conhecidos pelas fragrâncias que exalam e suas propriedades funcionais. O manjericão (Ocimum basilicum L.) possui substâncias em sua composição com propriedades antioxidantes e antimicrobianas, como o linalol e o eugenol. O objetivo deste trabalho foi avaliar as propriedades antioxidantes, antimicrobianas e termogravimétricas do óleo essencial de manjericão extraído por hidrodestilação a partir de três amostras diferentes, uma obtida comercialmente já seca, uma seca em estufa e outra liofilizada. Os dados demonstraram que o óleo essencial obtido do manjericão liofilizado apresentou maior atividade antioxidante pelos métodos de captura do radical ABTS•+ e pelo método da inibição da oxidação do complexo β-caroteno/ácido linoleico. Esse óleo também apresentou melhor desempenho de atividade antimicrobiana para diferentes microrganismos. Entretanto, o processo de secagem do manjericão em estufa permitiu um maior rendimento durante a extração. O óleo essencial do manjericão comercial, por sua vez, apresentou baixo rendimento e propriedades antioxidante e antimicrobiana piores que os demais. Na análise termogravimétrica (TG) foi possível perceber que as principais perdas de massa ocorreram em temperaturas entre 105 e 170 °C, com exceção do óleo essencial do manjericão comercial, que apresentou também um pico de degradação a 230°C A partir dos resultados obtidos, pode-se concluir que o óleo essencial proveniente da amostra seca em estufa apresenta maior viabilidade para aplicação comercial, pois teve um maior rendimento e propriedades próximas ao obtido da amostra liofilizada.

Published: May 2021

Objective: Cup therapy has an important place in traditional and complementary medicine applications. The purpose of our study, this is the first time to investigate the protective effect of cup therapy in rats on experimentally generated epileptic seizures in new rat modeling created by different anatomic regions.

Methods: In our study, 42 Wistar albino rats 3-4 months old (200-250 g) were used. Four other groups (n=7) except G3 and G4, 24 hours after cup therapy application, PTZ (35 mg/kg, sc., 0.2 cc) was injected, followed by behavioral epilepsy scoring.

Results: In the 'Open Area' and 'Elevated Plus Maze' tests, there was no behavioral difference between the cup therapy group and the control group (p > 0.05). Given all the parameters, the G4 group significantly reduces the seizure compared to other groups (p < 0.05). There is a significant difference in G2, G5 and G6 groups compared to G3 in the phases parameter (p < 0.05).

Conclusions: In this study, the new wet cup therapy (G2), which was applied for the first time, had a protective effect on seizures. G2, G5 and G6 groups are observed to suppress seizures compared to G3. Our findings are expected to contribute greatly to animal model analysis in the future.

Published: May 2021

Хиландарска библиотека подељена је у три целине, физички одвојене, засноване на различитим карактеристикама књига, разврстаних по хронолошком и формалном начелу. Тема овог рада је тзв. Средња библиотека, која је до данас, као целина, потпуно непозната јавности. Она садржи највећим делом књиге руског порекла, штампане црквенословенским језиком, у распону од 17. до 20. века. Оне су највећим делом богослужбене, а знатан је удео и „књига за читање“. Само мали део збирке је на руској грађанској ћирилици, а као подзбирка постоји и српска књига 18. века. Сви саставни делови Средње библиотеке укратко су описани у својим основним елементима, а изложена је и кратка историја њене обраде од седамдесетих година прошлог столећа.
Византинци и писана реч
Authors: Радић Радивој
Published: May 2021

Византијска цивилизација била је цивилизација рукописа и рукописних књига (кодекса) за које су коришћени папирус, пергамент и папир. Како би могле да се дистрибуирају до читалаца и како би се сачувале од пропадања, рукописне књиге су преписиване у скрипторијумима у којима нису деловали само монаси, него и световни људи различитих занимања. Књиге су биле веома скупе, а библиотеке јавне, царске, патријаршијске, монашке и приватне са не тако великим фондом рукописа. Како се византијска цивилизација ближила своме заласку, почела је селидба грчких рукописа из Визaнтије у латински свет западне Европе. На тај начин је велико наслеђе античке цивилизације сачувано и пренето у европске земље.
Кодиколошки или материјални опис рукописа?
Authors: Тријић Владан
Published: May 2021

У литератури је истакнута разлика између „кодиколошког“ и „физичког“ описа материјалних особина рукописних књига. Тим поводом, у раду се, најпре, у кратким цртама представља историјски развој кодикологије као научне дисциплине која се бави рукописном књигом, превасходно полазећи од физичких особина, како би се указало на могуће импликације које термин собом носи. Затим се пружа осврт на њен релативно слаб одјек у нашој научној средини, што се објашњава самосвојним развојем српске археографије, њеном јединственом методологијом, као и одсуством теоријске освешћености односа између кодикологије и археографије. Најзад, детаљније се пореде особине археографског и кодиколошког приступа рукописној књизи, уз закључак да није оправдано синонимно коришћење термина кодикологија и археографија, чак ни када им се садржина подудара и да би почетни део пуног археографског описа требало да се назива „материјалним“, како би се избегла забуна и спречио губитак драгоцених нијанси у значењу.

Links between White Settler Colony in Quebec and the Barriers to the Economic Integration of Skilled Latin American Immigrants
Authors: Calderon Moya Milagros
Published: May 2021

Although Quebec has gone through a period of strong economic growth, it is now struggling with a new labour shortage caused by the shrinking labor pool. Ironically, many foreign-educated immigrants face difficulties associated with entering the labour market and integrating into the workforce. Specifically, recent immigrants from African, Asian, and Latin American countries, who are considered part of visible minority groups, have faced barriers to entry. This paper focuses on the Latin American economic immigrant group and argues that the gap on human and social capital of minority group immigrants and majority group Quebecers cannot be explained simply by analyzing racially motivated actions. Rather, Quebec as a White colonial settler society plays a much more important role in making it very difficult for skilled immigrants to get equal levels of income. By analyzing postcolonial concepts, this document underlines how language politics, notions of citizenship and global neoliberal capitalism have shaped a harsh labour market that contributes to structural causes for inequality among skilled Latin American immigrants in Quebec.

Published: May 2021

Um dos aspectos mais relevantes da riqueza cultural do povo Boe Bororo é a expressão artística, que exibe uma exuberância e sofisticação estética muito própria. Este trabalho iconográfico faz uma delimitação em uma destas expressões, que é a pintura facial. Para isso, este trabalho, de forma introdutória, apresenta a história deste povo e suas divisões parentais, também chamadas de clãs, para que o leitor possa entender a lógica das divisões que esta arte assume em seu contexto cultural. É importante ressaltar que não se trata de uma pesquisa finalizada, pois a grandeza destas pinturas ainda não foram totalmente identificadas. Ela parte de um trabalho Etnográfico, Netnográfico e Bibliográfico, construído por um designer Boe Bororo e por um designer “braedog” (não indígena). Optou-se por utilizar o recurso de ilustração[1] digital para as representações visuais.

Philosophy of Financial Market
Authors: Milovidov V.
Published: May 2021

The existing financial theories fail to explain the causes of the contemporary financial crisis, in particular, of the 2008 crisis. The author claims that in order to understand what affects the current financial system we have, perhaps, to apply a philosophical approach. Such an approach seems to be supportive for comprehending the actual roles of the state and the market in this area. This will, at least partially, help to answer the question of why there are financial crises.

YOKSULLUKLA MÜCADELEDE TÜRKİYE’DEKİ BELEDİYELERİN SOSYAL YARDIM FAALİYETLERİNE İLİŞKİN BİR DEĞERLENDİRME
Authors: GİTMEZ Emin
Published: May 2021

Yoksulluk tüm Dünya’da yaygın olarak görülen önemli bir toplumsal sorundur. Yoksulluğu tamamen ortadan kaldırmak mümkün olmamakla birlikte, toplum kesimlerinin gelir kaynaklarını çeşitlendirerek ve gelir seviyelerini yükselterek yoksullukla mücadele edilebilir. Türkiye’de yoksullukla mücadelede en temel politika aracı sosyal yardımlardır. Sosyal yardımların toplumsal gelir dağılımı üzerindeki etkisinin ülkeden ülkeye farklılık göstermektedir. Türkiye’de yardımların düzensiz dağıtılması, yardım başına verilen tutarın düşük olması, yardım kuruluşları arasındaki iletişim eksikliği yardımların etkinliğini azaltmaktadır. Kamu tarafından verilen sosyal yardımlara ilişkin işlemler merkez ve yerelde faaliyet gösteren kurum ve kuruluşlarca yürütülmektedir. Yereldeki sosyal yardım faaliyetlerinin neredeyse tamamı belediyeler vasıtasıyla yerine getirilmektedir. Uygulamada belediyelerin sosyal yardımların dağıtımı konusunda şeffaf olmadığı değerlendirilmekle birlikte yardımların yararlanıcılara dağıtımında kayırmacılığın ön plana çıktığı görülmüştür.

Bu araştırmanın amacı, Yozgat’ta bir kamu hastanesinden hizmet almak üzere hastaneye başvuran bireylerin memnuniyet düzeylerinin belirlenmesidir. Araştırmanın evrenini, Yozgat’ta bir kamu hastanesinden hizmet alan hastalar oluşturmaktadır. Bu kamu hastanesinden günlük yaklaşık 400, aylık 12.500 ayaktan hasta hizmet almaktadır. Bu durumda araştırmanın örneklem büyüklüğü 373 olarak hesaplanmış ve 401 kişiye ulaşılmıştır. Araştırmada veri toplama aracı olarak Sağlık Bakanlığı Sağlık Hizmetleri Genel Müdürlüğü tarafından geliştirilen Sağlıkta Kalite Standartları (SKS)-Anket Uygulama Rehberi içerisinde yer alan “Hasta Deneyimi Anketi-Ayaktan Hasta” anket formu kullanılmıştır. Araştırma ölçeği maddelerinin 5 boyut altında toplandığı belirlenmiştir. Araştırmada en fazla memnun olunan boyutun çalışanlar olduğu, en az memnun olunan boyutun ise hastaneye ve hizmet birimlerine ulaşım olduğu görülmektedir. Ölçeğin tamamından memnuniyet ortalaması 3,78 (±0,61) olup, bu durum hastaneden memnuniyetin iyi olduğunu göstermektedir. Yapılan analizler sonucunda hasta memnuniyetinin hastaların yaş, cinsiyet, eğitim, sağlık sigortası, iş durumu ve aylık gelire göre istatistiksel olarak anlamlı şekilde farklılaştığı belirlenmiştir. Bu araştırma sonucunda başta hastaneye ulaşım olmak üzere hasta memnuniyetinin artırılması için çeşitli önerilerde bulunulmuştur.
Selective Inhibition of Heparan Sulphate and Not Chondroitin Sulphate by a Small, Soluble Competitive Inhibitor

The glycosaminoglycan, heparan sulphate (HS), orchestrates many developmental processes. Yet its biological role has not yet fully been elucidated. Small molecule chemical inhibitors can be used to perturb HS function and these compounds pro-vide cheap alternatives to genetic manipulation methods. However, existing chemical inhibition methods for HS also interfere with chondroitin sulphate (CS), complicating data interpretation of HS function. Herein, a simple method for the selective inhibition of HS biosynthesis is described. Using endogenous metabolic sugar pathways, Ac4GalNAz produces UDP-GlcNAz, which can target HS synthesis. Cell treatment with Ac4GalNAz resulted in defective chain elongation of the polymer and decreased HS expression. Conversely, no adverse effect on CS production was observed. The inhibition was transient and dose-dependent, affording rescue of HS expression after removal of the unnatural azido sugar. The utility of inhibition is demonstrated in cell culture and in whole or-ganisms, demonstrating that this small molecule can be used as a tool for HS inhibition in biological systems.
Evaluating the Prevalence of Psychological Outcomes in Chinese Healthcare Workers During the COVID-19 Pandemic
Authors: Sadjadi Ryan
Published: May 2021

The aim of this systematic review and meta-analysis is to evaluate the prevalence of depression, anxiety, insomnia, stress, PTSD, and distress in Chinese healthcare workers (HCWs) and the changes in prevalence before and after the peak incidence of COVID-19 in China. 20 cross-sectional studies assessing the aforementioned psychological outcomes were included. Eligible studies were searched from the following databases: PubMed, Scopus, and Web of Science. Comparative analysis based on the time period of the included studies was conducted to assess changes in prevalence before and after peak incidence. Additionally, subgroup analyses based on study quality, province, survey tools, gender and healthcare profession, frontline or non-frontline working status, and severity of psychological outcomes were conducted to evaluate the prevalence of outcomes across various study methods, geographic regions, and professions. The findings of this study suggest that the overall prevalence of depression, anxiety, insomnia, stress, PTSD, and distress before peak incidence were 36.2%, 34.2%, 22.4%, 31.3%, 9.8%, and 56.7% as opposed to 31.8%, 24.1%, 34.4%, 59.0%, 20.9%, and 40.7% after the peak. The higher prevalence of depression, anxiety, and distress prior to the peak incidence of COVID-19 in China and of insomnia, stress, and PTSD thereafter serve as evidence that the mental health decline of HCWs is dynamic and should be addressed with adaptive approaches that provide tailored treatments.
Quantitative tRNA-sequencing uncovers metazoan tissue-specific tRNA regulation
Authors: Pinkard Otis , Mcfarland Sean , Sweet Thomas , Coller Jeff
Published: May 2021

Transfer RNAs (tRNA) are quintessential in deciphering the genetic code; disseminating nucleic acid triplets into correct amino acid identity. While this decoding function is clear, an emerging theme is that tRNA abundance and functionality can powerfully impact protein production rate, folding, activity, and messenger RNA stability. Importantly, however, the expression pattern of tRNAs is obliquely known. Here we present Quantitative Mature tRNA sequencing (QuantM-tRNA seq), a technique to monitor tRNA abundance and sequence variants secondary to RNA modifications. With QuantM-tRNA seq we assess the tRNA transcriptome in mammalian tissues. We observe dramatic distinctions in isodecoder expression and known tRNA modifications between tissues. Remarkably, despite dramatic changes in tRNA isodecoder gene expression, the overall anticodon pool of each tRNA family is similar across tissues. These findings suggest that while anticodon pools appear to be buffered via an unknown mechanism, underlying transcriptomic and epitranscriptomic differences suggest a more complex tRNA regulatory landscape.

The performance of DNA-PAINT in biological samples is often constrained by strong background signals and non-specific binding events, both of which are exacerbated by high imager concentrations. Here we describe the procedure for conducting Repeat Domain DNA-PAINT, a method that substantially reduces imager concentration and thus suppresses spurious signals.
