Reading Fiction in the Tomsk City Public Library in the Late 19th — Early 20th Centuries
Authors: Timofeeva Yulija V. , Panchenko Anatoly M.
Published: April 2023

The relevance of reading is determined by its great role in the life of individual and society, due to its multifunctionality and priority position among other means of education and upbringing. Therefore, its study, including in historical retrospective, is an important area of the modern scientific research. Due to the lack of comprehensive studies of library reading in pre-revolutionary Siberia, this article for the first time examines the fiction books lending in the Tomsk City Public Library in the late 19th — early 20th centuries. The purpose of the article is to analyse the demand for fiction by users of the Tomsk City Public Library during the specified period. The tasks are to determine the share of fiction in the total amount of book lending; to make ratings of the most popular domestic and foreign authors of fiction works.

The authors use methods of comparative analysis, statistical and source studies. Data were collected from ten reports of the Tomsk City Public Library, as well as from its catalogue, that allowed us to recognize the source base of the article as representative. For the first time, the relative and average number of fiction lending was calculated. The obtained results demonstrate that in the late 19th — early 20th centuries the fiction book lending compounds at least two-thirds of all books lending in the Tomsk City Public Library.

The number of fiction lending exceeded the number of lending from other departments by dozens of times. The authors compiled and presented joint and separate ratings of popularity of Russian and foreign authors among users of the library, among whom there were almost only prose writers. It is proven that the works of domestic writers were more in demand among library users, and the percentage of female authors in the top 10 and top 30 was minimal. This study expanded the idea of reading fiction in pre-revolutionary Tomsk, its place in the reading circle and popular authors.

Authors: Maksimova Sargylana V.
Published: April 2023

The All-Russian scientific and practical conference with international participation “Gribanov Readings — 2022” was held on December 14—16, 2022 at the National Library of the Republic of Sakha (Yakutia). The article discusses the problems of the book culture of the regions of Russia; this theme was in the focus of attention of conference participants and was the subject of scientific discussion at the plenary session and in the course of the sections: “National and local history bibliography: history, status and new horizons”, “Reading infrastructure: research, exchange of experience”, “Historical and cultural studies to preserve the cultural heritage of the indigenous peoples of the Russian North, Siberia and the Far East” and “Digital transformation of libraries”. Within the framework of the conference, there were organized the round table “Modern Library Education: exchange of opinions of practitioners and theorists, managers and performers, teachers and students, readers and librarians” and the First Regional Festival of Scientific Research Cinema “Science Cinema”. The conference aroused great interest in the professional and scientific community. More than 130 specialists took part in it — theorists and practitioners of library and information activities, experts in the book industry, philosophers, historians, ethnographers, cultural scientists, art historians, employees of archives and museums from 30 regions of Russia, as well as from Belarus, Kazakhstan and Mongolia. The conference was aimed at identifying the main vectors of the history and current trends in the development of book culture in the regions of Russia, assessing the role of books and reading, bibliography, modern book publishing, discussing the key issues of the domestic book market, finding ways to digitally transform libraries and preserve the best traditions of the development of the book industry.
Maurice Maeterlinck’s Characters in Russian Book Graphics
Authors: Fomin Dmitry V.
Published: April 2023

The article discusses graphic cycles of Russian artists based on the works of the Belgian writer, playwright and philosopher Maurice Maeterlinck. This author’s enormous influence on the Russian culture of the Silver Age, alas, did not find an adequate and full-fledged embodiment in book graphics; however, it was reflected in several significant works of such prominent artists as S.Yu. Sudeikin, N.K. Roerich, B.I. Anisfeld, V.V. Spassky. In addition to belonging to the stylistic searches of Art Nouveau, their works on the themes of Maeterlinck’s plays are brought together by the desire for a symbolic and associative interpretation of the original source, the ability to use all the elements of the book ensemble to reveal its meaning.

The tradition of graphic interpretation of M. Maeterlinck’s stories and images was outlined in the 1910s, but then it was interrupted for several decades. Book artists began to show interest in the writer’s work again only in the 1970s. Illustrators of the late 20th — early 21st centuries focused their attention on the playwright’s most famous work in Russia — “The Blue Bird” fairy play. They tried various ways of its pictorial interpretation — from a purely realistic one (B.A. Dekhterev) to those much more stylized, openly grotesque (E.A. Silina, V.I. Tsikota), from attempts to strictly follow the spirit and letter of the original source (S.A. Kovalenkov) to free improvisations on the topic proposed by the author (G.A.V. Traugot, B.P. Sveshnikov, I.Yu. Oleinikov). The article notes the relevance of such dissimilar readings of the famous play, the value of their simultaneous presence in the book culture.
Alexander Tcherepnin in China: Chronicle of the Journey That Showed the Way to Chinese Musicians
Authors: Aizenshtadt Sergey A. , Czja Lujao
Published: April 2023

The article is devoted to the Chinese period of creative activity of the Russian composer-emigrant A.N. Tcherepnin (1899—1977). The propaganda of the ideas of synthesis of national music with modern Western compositional technique, conducted by Tcherepnin in China from 1934 to 1937, was of great importance for the development of Chinese musical culture. This article, for the first time, specifies many details of Tcherepnin’s activities in East Asia. There is given the exact chronology of all his four trips to China. The article provides an overview of his creative and pedagogical achievements, as well as family circumstances associated with each of these trips. The authors highlight the first composers’ competition in the history of China, organized on the initiative of Tcherepnin; the establishment of a publishing house promoting the works of Chinese authors; the concert, educational and pedagogical work in Shanghai and Beijing. The article concludes about the reasons why the composer went to China and stayed in this country for a long time. In addition to making a concert tour, a general interest in Chinese culture and a love interest for the future wife (as noted in previous studies), family problems related to the composer’s stepdaughter were of no small importance. There is provided biographical information about Tcherepnin’s relatives who played an important role in the history of his stay in China: Louisine Weekes, his first wife; Li Hsien Ming (Ming Tcherepnin), second wife; Camilla Horvat (Benois), aunt of Alexander Nikolayevich. The article tells about the creation history of the works written by Tcherepnin in China. On the basis of the study, there are revealed certain personality traits of Tcherepnin that led to such an impressive result of his musical and educational activities in China.
Long Aliphatic Chain Derivatives of Trigonal Lanthanide Complexes

Published: April 2023

The trigonal lanthanide complexes LnL (H3L = tris(((3-formyl-5-methylsalicylidene)amino)ethyl)amine) contain three pendant aldehyde groups and are known to react with primary amines. Reacting LnL (Ln = Yb, Lu) with 1-octadecylamine yields the novel aliphatic lanthanide complexes LnL18 (H3L18 = tris(((3-(1-octadecylimine)-5-methylsalicylidene)amino)ethyl)amine) where the three aldehyde groups are transformed to 1-octadecylimine groups. Herein the syntheses, structural characterisation and magnetic properties of LnL18 are presented. The crystal structure of YbL18 shows that the reaction of YbL with 1-octadecylamine leads to only very subtle perturbations in the first coordination sphere of Yb(III), with the Yb(III) ion retaining its heptacoordination and similar bond lengths and angles to the ligand. The three octadecyl chains in each complex were found to direct crystal packing into lipophilic arrays of van-der-Waals interaction-driven hydrocarbon stacking. The static magnetic properties of YbL18 were compared to those of the non-derivatised complex YbL. The energy level splitting of the 2F7/2 ground multiplet was found, by emission spectroscopy, to be very similar between the derivatised and non-derivatised complexes. A.c. magnetic susceptibility measurements on YbL18 and YbL diluted at 4.8 % and 4.2 % into the diamagnetic hosts LuL18 and LuL, respectively, revealed that the spin-lattice relaxation of both complexes is governed by a low temperature direct process and a high temperature Raman process. In the high temperature regime, the derivatised complex was also found to have faster spin-lattice relaxation, which is likely due to the increased number of phonons in the octadecyl chains.
Ingenious Dual Pulse Photoacoustic Tomography in Drug-Responsive Clinical Imaging Perspectives
Authors: Sen Diyasha , Bag Arijit
Published: April 2023

Detection of the real-time growth rate of cancer and visualization of the effectiveness of chemotherapy using live cell imaging techniques are yet to be invented. However, these could be conducive to monitoring the cancer treatment more precisely. In the present article, a new technique is proposed that will be able to accomplish the necessity mentioned earlier. The recent development and success of organometallic carbonyl clusters as photoacoustic contrast agents and cancer drugs have fetched a few freedom for the fate of new technologies towards the invention of time-dependent photoacoustic tomography (TD-PAT) that could ease the detection and treatment of cancer using advanced clinical chemotherapy.
Novel Patterns for Polymerization of Interlocked Molecular Cages
Authors: Chen Zhenghong , Wang Weihao , Zhang Shaodong
Published: April 2023

Polymerization of conventional polymers has been widely studied since the last century by forming covalent or mechanical bonds, where the latter leads to intrinsic topological properties of knots and links. However, the conventional perspective of discrete functional groups may suffer from limitation in polymerization of molecular cages by mechanical bonds of links. With a standpoint of combinatorics and statistical mechanics, we develop a practical, both graph based and kinetic model for this distinctive polymerization, indicating their diverse topological isomers and unique termination of polymerization, revealing their novel patterns from conventional linear polymers. This novel pattern and derived model may provide further strategies towards design and modification of molecular cages and their polymerization.
Defying Decomposition: The Curious Case of Choline Chloride

Published: April 2023

Chemists are exploring deep eutectic solvents (DESs) as alternatives to conventional solvents to meet modern sustainability, health, and safety requirements.[1–3] DESs incorporate renewable solids in task-specific liquids through large melting point depressions.[3] Yet, DES design is complicated by complex molecular interactions and a lack of comprehensive and reliable property databases.[3–6] Even measuring the melting properties of pure DES components can be challenging, as they often decompose before melting.[7–9] Here we overcame the decomposition of a quintessential DES constituent, choline chloride (ChCl). We measured its enthalpy of fusion (13.8 ± 3.0 kJ·mol−1) and melting point (687±9 K) by fast scanning calorimetry (FSC) combined with micro-XRD and high-speed optical microscopy. Our thermodynamically coherent fusion properties identify ChCl as an ionic plastic crystal[10] and demonstrate negative deviations from ideal mixing for ChCl— contradicting the conclusions based on previously assumed fusion properties.[5,7,11] We hypothesise that the plastic crystal nature of ammonium salts is at the basis of their resilience to melting when pure or mixed with other components. Our results thus pave the way for ionic plastic crystal-based DESs, liquid at accessible temperatures and over a broad range of compositions.
EnzymeMap: Curation, validation and data-driven prediction of enzymatic reactions
Authors: Heid Esther , Probst Daniel , Green William H. , Madsen Georg K. H.
Published: April 2023

Enzymatic reactions are an ecofriendly, selective and versatile addition, sometimes even alternative to organic reactions for the synthesis of chemical compounds such as pharmaceuticals or fine chemicals. To identify suitable reactions, computational models to predict the activity of enzymes on non-native substrates, to perform retrosynthetic pathway searches, or to predict the outcomes of reactions including regio- and stereoselectivity are becoming increasingly important. However, current approaches are substantially hindered by the limited amount of available data, especially if balanced and atom mapped reactions are needed and if the models feature machine learning components. We therefore constructed a high-quality dataset (EnzymeMap) by developing a large set of correction and validation algorithms for recorded reactions in the literature and showcase its significant positive impact on machine learning models of retrosynthesis, forward prediction, and regioselectivity prediction, outperforming previous approaches by a large margin. Our dataset allows for deep learning models of enzymatic reactions with unprecedented accuracy, and is freely available online.

Published: April 2023

The synthesis of air-persistent organic radicals (APORs) is challenging because of the presence of highly reactive species in air. It was found that N-heterocyclic carbenes (NHCs) are effective in stabilizing radical centers because of their bulky substituents and low-lying empty orbitals, thereby leading to the development of several APORs. Herein, we report the synthesis of two air-stable organic radicals derived from oxalyl chloride and cyclic (alkyl)(amino)carbene (cAAC), which included the unexpected formation of a known (amino)(carboxy) radical cation ([2]BF4) and a 1,2-dicarbonyl radical cation ([3]BF4). Most importantly, the reduced 3-oxetanone compound (4) was discovered as a new product originating from [3]BF4, which differs from the generation of NHC-based 1,2-dicarbonyl radicals. The highly strained 3-oxetanone 4 was obtained by a single-electron reduction of [3]BF4 with a mild reducing agent, chloride salt, and vice versa with a AgBF4 oxidant. Both [2]BF4 and [3]BF4 retained their intrinsic blue color and exhibited high air stability. Furthermore, [3]BF4 produced a temperature-dependent electron paramagnetic resonance spectrum.

Published: April 2023

The spread of pathogenic microorganisms on a large scale creates a health disaster for the world. Modifying the surface of the fabric so that it is antimicrobial pathogens with hydrophobic properties is one solution to inhibit the spread of microorganisms. Surface modification was carried out using Aloe vera powder as filler and polystyrene matrix with Aloe vera:PS composition variations of 1:5, 2:5, and 3:5 using the dip coating method and drying temperatures of 10◦C, 50◦C, and 90◦C. The characterization results that have been carried out with the best composition variations are 3:5 and 50◦C with a layered morphology using Scanning Electron Microscopy (SEM), resulting in a surface particle size of 21.243 nm, large contact angle/WCA using a Canon D350 camera with a size of 150.23◦, Fourier Transmission Infrared Analysis (FTIR) with the dominant functional group in the vibration band 2629 cm−1 indicates the presence of a long hydroxyl chain, the vibration band 1500 cm−1 with C-H stretching of the aromatic ring is caused by the characteristics of the polystyrene polymer and the wave number is 1700 cm−1 with stretching C=O which shows the characteristics of the carbonyl group in the Aloe vera sample is a flavonoid compound. The resistance of Aloe vera/PS solution to Klebsiella pneumonia resulted in a 20.18 mm diameter barrier showing strong resistance against bacteria and X-Ray Diffraction analysis showed that the AV powder was amorphous. Thus, the AV/PS 3:5 composition with a calcination temperature of 50◦C represents the greatest variation in the synthesis and characterization of hydrophobic thin films for pathogenic antimicrobial organisms.

Published: April 2023

The Open Unemployment Level (OUL) is the percentage of the unemployed to the total labor force. One of the provinces with the highest OUL score in Indonesia is West Java Province. If an object of observation is affected by spatial effects, namely spatial dependence and spatial diversity, then the regression model used is the Spatial Autoregressive (SAR) model. Quantile regression minimizes absolute weighted residuals that are not symmetrical. It is perfect for use on data distribution that is not normally distributed, dense at the ends of the data distribution, or there are outliers. The Spatial Autoregressive Quantile Regression (SARQR) is a model that combines spatial autoregressive models with quantile regression. This research used the data regarding OUR in West Java in 2020 from the Central Bureau of Statistics. This study develops to modeling the Open Unemployment Level in all province in Indonesia using modified spatial autoregressive model with the quantile regression approach. This study compares the estimation results based on SAR and SARQR models to obtain an acceptable model. In this study, it was found that the SARQR model is better than SAR at dealing with the problems of dependency and diversity in spatial data modeling and is not easily affected by the presence of outlier data.

Leptospirosis has worldwide occurrence and shows higher incidence in tropical areas. Equines can present several serovars according to geographic region and it is important analyze de possible contribution of animal displacement on the Leptospira spp. strains occurrence. This research aimed to conduct a serological investigation in an equine regiment belonging to the Brazilian Army Guard Cavalry, resident in an urban area of Rio de Janeiro municipality, but with history of displacement between different regions in Brazil. A microscopic agglutination test was performed in a serum bank of 197 horses using 29 Leptospira spp. strains. The test showed 94.92% positivity, with 90.36% of the animals presenting a positive result for two or more serovars. Higher titers (?1:400) could be detected in 54.31% of horses for at least one serovar, whereas seropositivity for more than one bacterial type occurred mostly at lower titers (<1:400). All animals were clinically healthy. Occurrence of serogroup Icterohaemorraghiae in urban areas was confirmed; however, equine serovars Bratislava and Australis presented low frequencies. The serovars Hardjo, Wolffi, and Canicola were detected, and indicated the presence of ruminants and dogs as reservoirs in proximity in some of the places frequented by the animals. It is suggested that travel history has contributed to the high frequency found and a possible greater contact with different types of Leptospira spp. Therefore, veterinarians should consider the history of geographic displacement and other animal species coexistence with horses when conducting their clinical investigation.

Published: April 2023

Dentre os retrovírus que causam doenças em gatos domésticos destacam-se o vírus da imunodeficiência felina (FIV) e o vírus da leucemia felina (FeLV). O objetivo deste estudo foi determinar a prevalência e os fatores de risco das infecções pelo FIV e FeLV em felinos atendidos em um hospital escola, durante o ano de 2014. Das 771 amostras testadas, houve prevalência de 5,2% (40/771) para o FIV, 1,8% (14/771) para o FeLV e 0,3% (2/771) apresentaram coinfecção. Dos infectados pelo FIV, 57,5% eram machos (23/40), 45% tinham acesso à rua (18/40) e 47,5% viviam em locais com múltiplos gatos (19/40). Dos infectados pelo FeLV, 50% eram machos (7/14), 42,9% tinham acesso à rua (6/14) e 64,3% viviam em locais com múltiplos gatos (9/14). A idade média dos infectados para o FIV (46 meses) foi maior do que dos infectados pelo FeLV (16 meses). O risco de infecção pelo FIV foi significativamente maior para gatos mais velhos, os com acesso à rua, os que conviviam com múltiplos gatos e de acordo com sua origem. Para os infectados pelo FeLV, sobressaíram-se como fatores de risco pacientes jovens e os que conviviam em residências com mais de 5 gatos. Medidas de manejo, testagem e restrição do acesso à rua são necessárias para prevenir a infecção de gatos por FIV e/ou FeLV.

Descreve-se os achados clínicos e patológicos do carcinoma pancreático em dois cães. O primeiro caso se refere a um cão sem raça definida, de quatro anos de idade, com histórico de anorexia, prostração e dispneia, vindo a óbito durante atendimento clínico. O segundo caso se refere a um cão sem raça definida, de oito anos de idade, com histórico de anorexia, adipsia e êmese há dez dias, sem melhora clínica, sendo eutanasiado posteriormente. Em ambos os casos os animais foram encaminhados para necropsia e amostras de tecidos foram enviadas para histopatologia e imuno-histoquímica. No caso 1, os principais achados macroscópicos consistiram em icterícia difusa e presença de massa expansiva, brancacenta, macia e gelatinosa no pâncreas e com metástase para estômago, fígado, rins, músculo abdominal, intestino e pele. Enquanto no caso 2, essa massa envolvia apenas pâncreas, omento e fígado. Em ambos os casos a histopatologia revelou massa não encapsulada, expansiva, constituída por proliferação epitelial pleomórfica arranjada em túbulos, cujo interior possuia material basofílico mucinoso. A mesma proliferação foi observada em estômago, fígado, rins, músculo abdominal, intestino e pele (caso 1) e em omento e fígado (caso 2). O diagnóstico de carcinoma pancreático foi estabelecido através dos achados histopatológicos, histoquímicos e imuno-histoquímico. Dentre os carcinomas pancreáticos destacam-se os neoplasmas mucinosos intraductais papilares, frequentemente diagnosticado em humanos e menos comumente em cães. Esta condição foi observada em cães adultos sem raça definida no Agreste da Paraíba e deve ser inserida no diagnóstico diferencial de patologias do trato gastrointestinal e hepáticas de cães.

Published: April 2023

Esta pesquisa tem como objetivo discutir o currículo intercultural na perspectiva da decolonialidade no âmbito da educação profissional. A ideia é propor uma reflexão teórica a partir de uma pesquisa bibliográfica sobre currículo intercultural e estudos decoloniais. A partir de uma metodologia qualitativa, a crítica foi desenvolvida considerando trabalhos teóricos dos seguintes autores sobre o currículo escolar formal: Miguel Arroyo (2013), Marise Ramos (2008), Dermeval Saviani (2011), José Gimeno Sacristán (2000), Maria Ciavatta (2005), Tomaz Tadeu da Silva (2009). Quanto aos estudos decoloniais, alguns dos autores considerados neste estudo são: Aníbal Quijano (2000), Walter Mignolo (2017), Vera Maria Ferrão Candau (2016), Catherine Walsh (2007, 2009), Boaventura de Sousa Santos (2010), autores cujos princípios são constituídos pelas contribuições da pedagogia crítica de Paulo Freire. Os resultados sugerem o conceito de interculturalidade como uma estratégia decolonial que pode ser vista como uma possibilidade de superação do currículo escolar formal como campo de relações de poder hegemônicas, bem como a base para a proposição do currículo como um projeto educacional voltado para o ser humano e emancipação social.

Designing an Equity-Centered Framework and Crosswalk for Integrated Elementary Computer Science Curriculum and Instruction
Authors: Strickland Carla , Ramirez-Salgado Andrea , Weisberg Lauren , Chandler LaToya , Di Domenico Jeanne , Lehman Elizabeth , Israel Maya
Published: April 2023

As computer science (CS) education becomes more prevalent in K-12 instruction, it is critical for educators, researchers, and curriculum developers to identify culturally responsive and pedagogically inclusive approaches that can increase participation, access, and feelings of belonging for students from historically marginalized communities. In response, we developed an equity-centered curricular framework and illustrative crosswalk that synchronizes three distinct pedagogical approaches: culturally responsive pedagogy (CRP), Universal Design for Learning (UDL), and project-based learning (PBL). We describe the framework’s theoretical underpinnings and explain how this framework informed the development of an integrated elementary science+CS curricular unit and provide examples of its implementation. Next, we describe the relationship between our framework, the integrated curricular unit, and educative materials designed to help teachers use the lessons and transform their practice. Finally, we highlight the framework’s potential for broader implementation in the quest to promote equitable CS instruction grounded in the experiences and perspectives of diverse student populations. The crosswalk is a graphical representation of the framework that communicates relationships amongst the elements in a digestible and practical way. This Equity-Centered Curricular Crosswalk addresses both lesson features and teacher practices, to underscore our belief that the responsibility of equity-based pedagogy should not be solely borne by teachers. As educators, researchers, and curriculum developers consider their interconnected roles and responsibilities in the enactment of CRP and UDL, the crosswalk provides an important link between equity-based instructional theories and the realities of classroom practices.

Objective: Due to the already observed importance of neutrophil-derived microvesicles (NMVs) in cancer development and progression, this study aims to quantify NMVs according to clinical staging and histological grade in the blood of breast cancer (BC) patients for a possible use in the liquid biopsy technique and personalized medicine, assisting in treatment decision. Methods: Peripheral blood was collected from 19 healthy women (control group) and from 51 patients with locally advanced BC (case group) in the Instituto Mário Penna, Belo Horizonte, Brazil. The study protocol was approved by the Ethics Committee of Instituto Mário Penna (CAEE 82703418.8.0000.5121). Clinical staging and histological grade data were obtained from the medical records of the study patients. The characterization of circulating NMVs was performed by immunophenotyping with specific neutrophil markers (CD66 and CD16), and quantification was performed by flow cytometry. Results: Our data showed a higher number of NMVs in BC patients, regardless of clinical staging and degree of tumor differentiation, when compared to the control group. Although no difference was observed in relation to the histopathological grade, the NMVs appear to have a potential diagnostic in BC patients. Conclusion: In a clinical scenario, they are going to use liquid biopsy as a candidate strategy to support clinical decision-making and guide therapeutic choices.

Published: April 2023

Objective: The aim of this study was to evaluate options for tissue expander and permanent implant and know the main indications, complications, effects on adjuvant treatment, impact on quality of life, and cost-effectiveness of each one. Methods: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and MetaAnalyses (PRISMA) statement. For the identification of articles on the topic, PubMed, EMBASE, and Cochrane databases were searched from 2000 to 2021, and only English terms were used. The inclusion criteria were as follows: meta-analyses, systematic reviews, randomized or nonrandomized clinical trials, and observational studies. The analysis of the studies was descriptive. Results: The initial search in the databases identified 65 articles, and after reviewing the inclusion criteria, 32 studies were available. According to relevance, 20 studies were excluded due to unavailability of the full text or irrelevance for the study purpose. Twelve articles were included with an average of 1068 patients per study. The studies were heterogeneous with results mostly favorable for reconstruction at a stage with permanent implant. Conclusion: Singlestage breast reconstruction is a promising strategy with acceptable complication rates and the described advantages. Post-mastectomy radiotherapy increases complications. Finally, studies are still heterogeneous, both in terms of methodologies and results, so it is not possible to extrapolate information without bias.

Published: April 2023

Objective: The aim of this study was to compare the protein expression of biglycan (BGN) in normal breast tissue and in breast cancer using deep learning and digital HScore techniques. Methods: In this case-control study, 24 formalin-fixed, paraffin-embedded tissues were obtained from pathological archives for analysis. Normal breast (n=9) and breast cancer (n=15) tissue sections were analyzed by immunohistochemistry using BGN monoclonal antibody (M01 – Abnova), clone 4E1-1G7 at dilution 1:300 at pH 6, and 3,3’-diaminobenzidine (DAB) as the chromogen. Photomicrographs of the slides were analyzed using the ImageJ software with “color deconvolution”. After selecting the regions of interest (ROI), deconvoluted panels with DAB only were quantified using arbitrary DAB units. Another set, with higher magnification without ROI selection, was submitted to the inception V3 deep neural network image embedding recognition model. Next, supervised neural network analysis, using stratified 20-fold cross-validation, with 200 hidden layers, ReLu activation, and regularization at α=0.0001 were applied for SDLNN. The sample size was calculated for a minimum of seven cases and seven controls, having a power of 90%, an α error=5%, and a standard deviation of 20, to identify a decrease from the average of 40 DAB units (control) to 4 DAB units in cancer. Ethical approval was obtained from the Hospital de Clínicas de Porto Alegre Ethical Review Board (2019/0337). CAAE 15329119.9.0000.5327. Results: BGN expression (mean±SD) was 6.1±3.9 in breast cancer tissue, while in normal breast tissue, it was 39.6±21.9, using D-HScore (p=0.0017, student t-test, Welch corrected). SDLNN was able to correctly classify 110 out of 129 photomicrographs of the dataset using DAB panels only, with a classification accuracy of 85.3% (95%CI 78.1–90.3%) and the area under the curve of 94.3%. Conclusion: D-HScore and SDLNN revealed that BGN protein expression is reduced in breast cancer tissue, compared to normal tissue. The use of SDLNN seems to be a potential tool for image analysis in histological samples.

As tecnologias desempenham um papel crucial na prevenção e mitigação de catástrofes naturais e humanas. Algumas tecnologias avançadas, como sistemas de alerta precoce, sensores de monitoramento de clima e ambiente, drones e robôs de resgate, contribuem para identificar e acompanhar eventos potencialmente perigosos, permitindo que as autoridades tomem medidas preventivas com antecedência.
Pensar todos os mecanismos indutores do desenvolvimento sustentável, bem como estabelecer parâmetros essenciais de ordenamento, orientação e eficácia por meio dos distintos estudos realizados pelos pesquisadores da coletânea, evidenciam-se em linguagens indutoras para a percepção de alternativas e meios imprescindíveis para a estruturação de todo o conjunto de ações estruturantes pensadas para cada fenômeno mencionado.
Aumentando, assim, a capacidade de resposta e eficiência das equipes de resgate, por meio do uso de sistemas de comunicação avançados, equipamentos de proteção individual, ferramentas de busca e salvamento, entre outros recursos, além de fomentar políticas públicas capazes de atender às distintas demandas decorrentes em distintos contextos de suas ocorrências nos mais variados territórios e espaços.
Apesar de auxiliar na prevenção e redução dos impactos das catástrofes, as tecnologias não são a solução única ou suficiente para o problema. É fundamental que as autoridades públicas e privadas assumam sua responsabilidade na gestão de riscos e planejamento de ações de prevenção e resposta, além de considerar os fatores sociais, econômicos e ambientais que podem contribuir para a ocorrência desses eventos.
Hermeneutic Analysis of International Stories: Lived Experiences During the COVID-19 Pandemic

Published: April 2023

Writing stories about distressing experiences can be a step in navigating traumatic events. With favorable conditions for novel zoonotic disease spurring future health crises, we aimed to (1) Gain insights into the lived experiences of individuals during the early phase of the COVID-19 pandemic; (2) Uncover gaps in care that individuals identified within their healthcare, community, and family settings; and (3) Understand commonalities among perceived psychological well-being of individuals working within their health care settings. Following examination by a midwestern university institutional review board, this study was found exempt from human subject research. A hermeneutic phenomenological framework guided the inquiry. Eighty-six stories came from 11 countries, with 64% submitted by healthcare team members. We found: (1) Lived experiences evolved from a fluid and dynamic process by which personal knowledge emerged from the interaction between individuals’ internal responses to the pandemic and their external behaviors that assisted with coping; (2) Inequities existed in how global resources and information to treatment and mitigation of C-19 was communicated within health care systems, communities, and families, impacting personal psychological safety and well-being; and (3) Spiritual fortitude supported individuals’ well-being as they coped with adversities related to psychologically unsafe work milieus, inequities, and losses. Communal activities within hospital, family and/or community settings improved the well-being of individuals’ lived experiences. Our findings will inform hospital leadership, communities, and families of individuals’ lived experiences early in the pandemic. We provide recommendations that assist in the management of future health crises involving novel viruses.

The lack of water: A problem that grows every day
Authors: López-Oteiza ME  , Navarro-Venegas C
Published: April 2023

If 75% of the planet is made up of water, then we shouldn't worry about anything. The problem is that desalination systems are neither sufficient nor efficient, rather the adjective to use is: scarce. Although we live in the 21st century, we still do not have the systems, and what yesterday was a science fiction movie; fighting for water, today seems to be a reality outside our door. There are various doctorates throughout the world and perhaps a few students see something as close as a topic of work and many are dedicated to more striking sciences such as new technologies in relation to computing, medicine or engineering. However, this is precisely the sciences called to partly solve what this article calls for. What university careers can be aware of or aware of this?

The health effects can be serious if it is not promptly identified and acted upon. This paper presents a case of 69 years old female patient suffered debilitating effects of Vitamin D Toxicity through self-medication, who was treated with Yoga Prana Vidya System by a team of two healers successfully. Method: This paper uses case study method of collecting data from patient records, healers’ records and patient feedback through her family. Results: Within 10 days of YPV healing, the bedridden patient regained strength progressively and was able to rise up and walk with support. After the next 4 weeks of YPV healing support she was able to do household chores and walk longer. After next four months, her blood tests showed normal levels of Vitamin D. Conclusions: Health care providers should monitor use of these supplements, especially in the population at risk due to high dose requirements. Yoga Prana Vidya system of healing offers support system needed in the management of excessive use of Vitamin D supplements, rehabilitating the patients holistically as is observed in this case study. Further research on this topic is recommended.
