Blood preservatives (anticoagulants) prevent blood from clotting while ensuring that the concentration of the component to be analysed stays constant prior to the analytical procedures. The study was aimed to evaluate the effects of different anticoagulants, such as ethylenediaminetetraacetic acid (EDTA), fluoride oxalate, sodium citrate and lithium heparin, on the haematological parameters of African catfish (Clarias gariepinus). Forty fish were obtained and separated into four groups representing the four treatments. Blood samples were collected from ten fish from each group and stored in separate anticoagulant laden bottles. Lithium heparin was used as control in this experiment. Each sample was processed, and values of the parameters were recorded. The RBC, haemoglobin, and PCV of the anticoagulants used were similar as no significant difference (P > 0.05) was revealed among the treatments. The heterophil levels of fluoride oxalate treatment group was significantly higher than control, this in turn led to an increase in HLR (heterophil-lymphocyte ratio). Therefore, the haematologic alteration observed in this study, which include heterophilia associated with fluoride oxalate anticoagulant, should be put into consideration when making a choice of anticoagulants for haematological analysis in C. gariepinus.

Authors: Botello Chávez Carlos Noé 
Published: December 2024

Este artículo presenta el Método para un consumo responsable de cannabis medicinal, diseñado para optimizar los efectos terapéuticos del tratamiento y evitar la dependencia. La metodología consta de dos etapas: el “acercamiento,” que implica una dosis inicial elevada para activar los receptores CB1 y CB2, y la “dosificación,” donde se reduce progresivamente la dosis hasta encontrar un equilibrio que permita mantener la funcionalidad en la vida diaria. Se aborda el papel del acompañamiento cannábico en la supervisión y personalización del tratamiento, proporcionando un apoyo profesional durante el proceso de adaptación. La implementación de este método, junto con la variación de cepas recomendada por el sistema de Clasificación PCME, permitió a 5 de 6 sujetos maximizar los beneficios terapéuticos del cannabis,recuperando la sensación del efecto séquito reduciendo su consumo hasta 50% para los 5 de 6 sujetos, asegurando un tratamiento integral y adaptado a cada paciente.
«ЛЕГКО ЛИ БЫТЬ ЖУРНАЛИСТОМ?» (К ВОПРОСУ О ПРОФЕССИОНАЛЬНОЙ САМОИДЕНТИФИКАЦИИ АКТОРОВ МЕДИАПРОСТРАНСТВА УРФО)
Authors: ГАВРИЛОВ В.В. 
Published: December 2024

Статья посвящена описанию проблем профессиональной самоидентификации совре- менных журналистов. На основе данных, полученных в результате анкетирования, а также опираясь на материалы творческих работ (эссе) на тему «Легко ли быть жур- налистом?» студентов СурГПУ, автор отмечает наметившиеся и все более усиливающиеся противоречия между социальным заказом в условиях цифровизации СМИ и восприятием профессии, своего места в медиапространстве как начинающими, так и уже состоявшими- ся журналистами. Акторы медиапространства УрФО зачастую не фиксируют актуальных трансформаций в СМИ и считают, что обладают достаточными компетенциями, чтобы быть конкурентоспособными на рынке медиауслуг. В условиях усиливающейся конкурен- ции с «общественными журналистами» и искусственным интеллектом такая стратегия для профессиональных журналистов является неэффективной. В этой связи предлагается в рамках отечественного медиаобразования скорректировать подходы к обучению буду- щих журналистов и выстроить учебные курсы, а также производственные практики таким образом, чтобы учесть новейший социальный запрос и те изменения, которые происходят в отечественной журналистике (цифровизация, конвергенция жанров, виртуализация ме- диапространства).
The article is devoted to the description of the problems of professional self-identification of modern journalists. Based on the data obtained as a result of the survey, as well as based on the materials of creative works (essays) on the topic "Is it easy to be a journalist?" by the students of SurGPU, the author notes the emerging and increasingly growing contradictions between the social order in the context of digitalization of the media and the perception of the profession, their place in the media space by both novice and already established journalists. Actors in the media space of the Ural Federal District often do not record current transformations in the media and believe that they have sufficient competencies to be competitive in the media services market. In the context of increasing competition with "public journalists" and artificial intelligence, such a strategy is ineffective for professional journalists. In this regard, it is proposed to adjust approaches to the training of future journalists and build educational programs within the framework of domestic media education.
Cambios normativos en materia laboral en el contexto de la Constitución de la República del Ecuador 2008 con relación a la irrenunciabilidad de derechos
Authors: Guadalupe Oviedo Andrea Lisette , Guerra Sánchez Mayra Alejandra 
Published: December 2024

A partir del proceso constituyente y con la promulgación de la Constitución de la República del Ecuador en 2008 dentro de nuestro país se han evidenciado cambios normativos que responden a la necesidad del legislador de precautelar y garantizar los derechos laborales, logrando la prevalencia de los principios base que regulan el derecho del trabajo y la inclusión de diversas figuras que se han incorporado con el afán de lograr una protección eficaz al trabajador por su situación de desventaja frente al empleador. En esta investigación se analizará la normativa, doctrina y jurisprudencia con relación a la prestación de servicios lícitos y personales de manera directa y bilateral, aspectos sobre los cuales deben girar las relaciones de trabajo y en las que debe existir primacía en el reconocimiento de derechos fundamentales inherentes al trabajador; sobre todo desde la arista del principio de irrenunciabilidad de los derechos y la prevalencia del principio de progresividad que asegura un mínimo de dignidad existencial a los trabajadores. El abordaje de la prohibición de la tercerización laboral, la configuración de la no afiliación a la seguridad social como un delito y la configuración del acoso laboral, nos permitirán examinar si de conformidad al principio tutelar o protectorio la Constitución establece mecanismos de protección y lineamientos base para que la normativa sea aplicada en pro de siempre buscar mejores condiciones y avances en cuanto a derecho laboral se refiere.

Introdução: A tuberculose é uma doença infecto-contagiosa cuja principal via de transmissão é a respiratória. Deste modo faz-se essencial a investigação de contatos de doentes para controle da doença. Métodos: Estudo epidemiológico observacional descritivo, transversal realizado por meio de análise de dados secundários do Sistema de Informação de Notificação de Tuberculose (TBWeb - Sistema de Controle de Pacientes com Tuberculose). Resultados: Entre janeiro de 2020 e dezembro de 2021 foram diagnosticados 252 casos de tuberculose no município de São José do Rio Preto-SP. A busca ativa dos contatos foi realizada, observando-se que os 252 doentes possuíam 493 contatos, uma média de 1,96 contato/caso. Ao avaliarmos a eficiência da busca, o município foi capaz de investigar 78% dos contatos identificados. O tratamento para infecção latente de tuberculose (ILTB) foi indicado para 168 contatos (34,08%) e iniciado por 81,55% destes. Porém, é importante ressaltar que o tratamento para ILTB não é feito em dose única e o sistema TBWeb registra apenas a data de início do tratamento, não sendo possível quantificar os pacientes que abandonaram o tratamento Conclusão: Faz-se necessária a adoção de novas medidas, principalmente no que diz respeito à conhecimento, adesão e conscientização da população sobre a Tuberculose. Ademais, o Sistema Nacional de coleta de dados deveria conter mais informações, entre as quais destacam-se dados sobre o tratamento da ILTB, especialmente acerca do seguimento e alta de pacientes e contatos.

Diabetes mellitus gestacional (DMG) é uma patologia relacionada com a quebra da homeostase da glicose, bastante comum na gestação, e que pode trazer consequências maternas e fetais. Nesse contexto, o presente trabalho possui como objetivos elucidar a importância do pré-natal no controle da diabetes mellitus, assim como elencar as principais complicações do DMG. Para isso, foi realizada uma revisão integrativa de literatura, cuja questão de pesquisa foi elaborada a partir da estratégia PICO. A busca na literatura foi realizada na plataforma PubMed e Google Acadêmico utilizando a combinação de palavras-chave cadastradas nos Descritores em Ciências da Saúde (DECs): Diabetes Mellitus AND Complicações AND Pré-natal AND Tratamento. Foram incluídos artigos científicos que contemplam a temática, publicados no período de 2020 a 2024, nos idiomas português e inglês. Foram excluídos artigos de revisão não sistemática e artigos duplicados nas plataformas selecionadas. Ao todo, foram usados 17 estudos para desenvolver todo o trabalho, de modo que, foi observado que o pré-natal é um momento da gestação, no qual a mulher pode ter a atenção de uma equipe multiprofissional, voltada para a detecção precoce e prevenção de doenças, a fim de evitar complicações como macrossomia, necessidade de unidade de terapia intensiva (UTI), intubação, hipoglicemia neonatal e anomalias congênitas. Assim, a equipe pode orientar a gestante quanto a alimentação e a atividade física e avaliar a necessidade de tratamento medicamentoso. Portanto, o pré-natal é o pilar para que a gestação ocorra dentro da normalidade e com o acompanhamento adequado e monitorado.

AbstractCarbon‐based materials have been widely used in heterogeneous catalysis because of their advantages of high surface area, thermal stability, and chemical inertness. However, their role in the catalysis is not fully understood although most studies conclude that the coupling between the carbon support and catalyst could reduce the charge transfer resistance and improve the kinetics of catalytic reactions such as water splitting. In this study, a carbon‐modified FeP2 electrocatalyst with a one‐step strategy is synthesized. The tensile strain is introduced in situ in the ab crystal plane of the FeP2 catalyst. This leads to charge redistribution between H and O atoms in the OH bonds and enhances the adsorption of reaction intermediates. In the water oxidation process, this results in a decrease in the energy barrier for the rate‐determining step, specifically, the chemical step of *OH adsorption preceded by one‐electron transfer. Benefiting from the optimized adsorption energy, the strained catalysts exhibit excellent oxygen evolution reaction (OER) activity with a low overpotential in addition to their increased stability. This study provides a new strategy for the introducing of strains in functional materials and provides new insights into the influence of carbon modification on OER activity.

AbstractHerein, various 3D additive manufacturing approaches are reviewed in terms of two important figures of merit: maximum voxel printing rate and minimum voxel size. Voxel sizes from several 100 µm down to the 100 nm scale are covered. Original results on multifocus two‐photon printing at around voxel printing rates of 107 voxels s−1 are presented in this context, which significantly surpass previous best values. These advances are illustrated by and applied to the making of microstructured 3D (chiral) mechanical metamaterials that are composed of more than one‐hundred‐thousand unit cells in three dimensions. Previous best values for unit cells of similar complexity are smaller by two orders of magnitude.

AbstractWater electrolysis is an emerging energy conversion technology, which is significant for efficient hydrogen (H2) production. Based on the high‐activity transition metal ions and metal alloys of ultrastable bifunctional catalyst, the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are the key to achieving the energy conversion method by overall water splitting (OWS). This study reports that the Co‐based coordination polymer (ZIF‐67) anchoring on an indium–organic framework (InOF‐1) composite (InOF‐1@ZIF‐67) is treated followed by carbonization and phosphorization to successfully obtain CoP nanoparticles–embedded carbon nanotubes and nitrogen‐doped carbon materials (CoP‐InNC@CNT). As HER and OER electrocatalysts, it is demonstrated that CoP‐InNC@CNT simultaneously exhibit high HER performance (overpotential of 153 mV in 0.5 m H2SO4 and 159 mV in 1.0 m KOH) and OER performance (overpotential of 270 mV in 1.0 m KOH) activities to reach the current density of 10 mA cm−2. In addition, these CoP‐InNC@CNT rods, as a cathode and an anode, can display an excellent OWS performance with η10 = 1.58 V and better stability, which shows the satisfying electrocatalyst for the OWS compared to control materials. This method ensures the tight and uniform growth of the fast nucleating and stable materials on substrate and can be further applied for practical electrochemical reactions.

AbstractFlexible electronics, such as flexible displays, batteries, and sensors, are under active development, and their mechanical reliability under repeated mechanical deformations is receiving a lot of attention. The mechanical stress under simple bending has been widely investigated, and the neutral plane located tensile and compressive region has been suggested for stress‐free zone under bending. However, to develop highly reliable twistable electronics, it is essential to elucidate the stress evolution during complex twisting deformation, and determine the stress‐free zone in twisting. The mechanical reliability of flexible indium tin oxide and Cu patterns during repeated twisting motions is reported. For fixed twisting, the patterns at the center show higher stability, but for free twisting, the patterns at the edge exhibit superior mechanical reliability. The mechanical stress evolution in twisting motion is analyzed by finite element method simulation, and the stress‐free zone according to twisting motion and base is proposed. Finally, the stress‐free zone is verified by conducting real twisting tests, such as the twisting motion of the human body. This study based on experimental reliability testing and computational simulation can provide guidelines to develop highly reliable twisting electronics.
Identification of cell‐to‐cell heterogeneity through systems engineering approaches

Published: January 2020

AbstractCells in a genetically homogeneous cell‐population exhibit a significant degree of heterogeneity in their responses to an external stimulus. To understand origins and importance of this heterogeneity, individual‐based population model (IBPM), where parameters follow probability density functions (PDFs) instead of being constants, has been previously developed. However, parameter identification for an IBPM is challenging as estimating PDFs is computationally expensive. Also, because of experimental limitations and nonlinearity of models, not all parameters' PDFs are identifiable. Motivated by the above considerations, a new methodology is proposed in this study. First, a subset of parameters whose PDFs is identifiable are determined through sensitivity analysis, and only these PDFs are estimated. Second, an artificial neural network model is developed to find an empirical relation between these parameter and output PDFs to reduce computational costs of the parameter identification. The proposed approach is validated by estimating PDFs of parameters of a tumor necrosis factor‐α signaling model.

Published: January 2020

AbstractWaste heat recovery for wet flue gas desulfurization (WFGD) system is quite necessary so that both heat and water consumption can be saved. However, formerly, there existed no clear concept about the upper limit quantity of waste heat that can be recovered for a target WFGD system, and where the final operation status of WFGD system after waste heat recovered will be located is also absent. Therefore, in the current paper, a methodology is developed first to simulate the magnesium method desulfurization system with circulating water considered using Aspen Plus V8.4. After validation, the methodology with slight modification is then used to investigate the theoretical maximal quantity of waste heat that can be recovered under different conditions and study the corresponding variation tendencies of updated thermal and water equilibrium states. Desulfurization efficiency is also discussed qualitatively. Results indicate that there exist maximal 1.41 to 2.27 MW heat that can be recovered at WFGD system for an 80 t/hr coal‐fired boiler, equivalent to save standard coal from about 1,385 to 2,230 t/a. All the streams temperature are reduced after recovering waste heat, but different streams behave different variation tendency. Water consumption and desulfurization efficiency also could get improved.
Monitoring Polysulfide Solubility and Diffusion in Fluorinated Ether‐Based Electrolytes by Operando Raman Spectroscopy

Published: January 2020

AbstractPolysulfide (PS) solubility is a key property of Li−S battery electrolytes for the conversion reaction(s) at the electrolyte‐electrode interface. When PSs shuttle between the composite C/S cathode and the lithium metal anode, however, this leads to a continuous loss of active material and thus rapid capacity fading. In order to restrict the shuttle effect, fluorinated ethers have recently been proposed as a remedy; by only sparsely dissolving PSs they physically block the diffusion. We show here how the diffusion of PSs in fluorinated ethers, as monitored by operando Raman spectroscopy, is selective and that only short‐chain PS (
) are soluble and diffuse. This fundamental observation can be used to further leverage the practical performance of Li−S batteries by novel electrolyte design.

AbstractBackgroundCohort studies have shown that bariatric surgery may reduce the incidence of and mortality from cardiovascular disease (CVD), but studies using real-world data are limited. This study examined the impact of bariatric surgery on incident CVD, hypertension and atrial fibrillation, and all-cause mortality.MethodsA retrospective, matched, controlled cohort study of The Health Improvement Network primary care database (from 1 January 1990 to 31 January 2018) was performed (approximately 6 per cent of the UK population). Adults with a BMI of 30 kg/m2 or above who did not have gastric cancer were included as the exposed group. Each exposed patient, who had undergone bariatric surgery, was matched for age, sex, BMI and presence of type 2 diabetes mellitus (T2DM) with two controls who had not had bariatric surgery.ResultsA total of 5170 exposed and 9995 control participants were included; their mean(s.d.) age was 45·3(10·5) years and 21·5 per cent (3265 of 15 165 participants) had T2DM. Median follow-up was 3·9 (i.q.r. 1·8– 6·4) years. Mean(s.d.) percentage weight loss was 20·0(13·2) and 0·8(9·5) per cent in exposed and control groups respectively. Overall, bariatric surgery was not associated with a significantly lower CVD risk (adjusted hazard ratio (HR) 0·80; 95 per cent c.i. 0·62 to 1·02; P = 0·074). Only in the gastric bypass group was a significant impact on CVD observed (HR 0·53, 0·34 to 0·81; P = 0·003). Bariatric surgery was associated with significant reduction in all-cause mortality (adjusted HR 0·70, 0·55 to 0·89; P = 0·004), hypertension (adjusted HR 0·41, 0·34 to 0·50; P &lt; 0·001) and heart failure (adjusted HR 0·57, 0·34 to 0·96; P = 0·033). Outcomes were similar in patients with and those without T2DM (exposed versus controls), except for incident atrial fibrillation, which was reduced in the T2DM group.ConclusionBariatric surgery is associated with a reduced risk of hypertension, heart failure and mortality, compared with routine care. Gastric bypass was associated with reduced risk of CVD compared to routine care.
