Authors: Girod Gastón , García de la Cárcova Alejo , Petrocchi Inés
Published: August 2021

Desde el comienzo de la historia del diseño industrial –con énfasis en el diseño de mobiliario– un variado universo de profesiones, materiales, tecnologías, ideologías e intereses económicos irán delineando un repertorio objetual con la consecuente instauración de un canon. Sus protagonistas, desde el siglo diecinueve hasta la actualidad, conformarán una red de movimientos migratorios motivados por intereses propios, en algunos casos, o como consecuencia del contexto político, social y cultural, en otros. El presente trabajo hace un recorrido por dichas migraciones y estudia su influencia en la formación de los profesionales, la construcción de los programas de enseñanza, la producción de la cultura material y la ampliación del canon.
Centennials en la universidad: prosumidores de contenidos en el aula
Authors: Bertuzzi María Florencia
Published: August 2021

En un contexto tan complejo, seguir entendiendo la educación, el diseño y la enseñanza como se ha venido desarrollando hasta ahora, resulta casi surreal. Las aulas universitarias actuales se encuentran colmadas de estudiantes que pertenecen a lo que algunos autores definen como Centennials, I-GEN, D-GEN (generación digital) o Generación Z. Por tal motivo, es posible determinar que los docentes universitarios enfrentan un gran desafío, teniendo en cuenta que enseñarles no resulta tarea fácil, entendiendo que esta generación de estudiantes ha nacido en pleno desarrollo de la era digital lo que implica un acercamiento al conocimiento que dista bastante de las formas tradicionales de enseñanza. El mundo se encuentra en transición, muchos de los antiguos paradigmas están cambiando a consecuencia de las nuevas exigencias de la sociedad, nuevos estilos de vida, macrotendencias actuales, cambios culturales y, principalmente, del contexto político, económico y social a nivel global.

Authors: Suil Aravena Katherine Verónica , Gatica Ramírez Pamela Petruska
Published: August 2021

Este artículo presenta el bordado como artefacto cultural femenino, entendiendo que el bordado concebido como una actividad femenina menor se ha ido transformando, pudiendo ser un acto político, para el activismo y la memoria. Es en donde el diseño se puede articular como un actor cuya experiencia se hace vivencial además de productora de artefactos de uso. A través de la revisión teórica se enmarca el proyecto de un relato textil realizado en el contexto del denominado estallido social chileno acontecido en octubre de 2019. El proyecto constituye una bitácora a través de bordados elaborados durante el periodo de octubre del 2019 y marzo del 2020, para ser exhibido en plataformas digitales.
Método proyectual tradicional y su aplicabilidad en el contexto de ambientes virtuales de aprendizaje
Authors: Cevallos Sánchez María Dolores
Published: August 2021

Es posible aplicar el método proyectual tradicional en los ambientes virtuales de aprendizaje. Es una interrogante repetida desde el momento coyuntural de cambio que se está viviendo. Más allá de si es o no aplicable, la respuesta es que necesariamente se tiene que adaptar y evolucionar, en concordancia. Desde un enfoque de materias proyectivas, dentro del campo del Diseño Gráfico, donde se deben desarrollar propuestas tangibles desde una base conceptual, es inevitable trabajar con el método proyectual, en una modalidad de taller que requiere una constante retroalimentación de los avances del proyecto. Esto tiene sentido en tanto y cuanto se pueden dilucidar progresos y correcciones sobre la propuesta planteada por el estudiante. Al estar mediados por una tecnología que salva la distancia, los problemas existen, sobre todo al no estar "ahí" ambas partes, docente y alumno para discutir. Todo se hace en una pantalla. No se boceta ni esquematiza tangible ni directamente, esto se agrava si la clase no se da en sincronicidad. Se propone que la adaptación de la TIC que media el proceso dependa también de la adaptación del método del docente. Haciendo énfasis en el nuevo protagonismo del profesor cuya identidad es hoy por hoy, una pantalla omnipresente en todos los ambientes del estudiante. La idea es encontrar los puntos medulares de una resignificación del docente como una nueva imagen apoyada en un lenguaje audiovisual en donde la modificación tanto del modelo pedagógico como actitudinal en los encuentros sincrónicos y asincrónicos puedan ser provechosos dentro del perfeccionamiento curricular.
Modelo Didáctico Proyectual para Entornos Virtuales (MDPEV)
Authors: Marmolejo Cueva Melba Cristina , Vásquez Coisme Ladys Diana
Published: August 2021

Incorporar a las TIC en la dinámica educativa de manera que aporte significativamente al proceso formativo ha dejado de ser un reto para convertirse en un asunto prioritario debido al contexto pandémico que afecta a la comunidad global. El nuevo modelo de interacción docente-alumno está soportado por medios digitales que brindan herramientas para facilitar –en la medida de las posibilidades– al proceso educativo, sin embargo, existen aspectos esenciales en la formación, relacionados con las competencias, así como los resultados de aprendizaje, que deben tratarse a profundidad por la complejidad de su estructura y alcances. En este punto es importante establecer estrategias, métodos y técnicas destinadas al aprendizaje basado en proyectos en el espacio de trabajo virtual. El Diseño Gráfico posibilita la transformación de la teoría en práctica por medio de la creación de soluciones innovadoras. En esencia, es una disciplina proyectual porque obedece a procesos para su desarrollo, implementación y evaluación. Consecuentemente, la programación curricular presenta materias de tipo proyectual, siendo más definido en casos específicos y menos evidentes en otros. Este artículo describe un modelo de trabajo orientado a entornos virtuales, denominado Modelo Didáctico Proyectual para Entornos Virtuales (MDPEV), construido a partir de la integración del Modelo Didáctico Alternativo MDA, también llamado Modelo Integrador junto a las Metodologías Centradas en la Actividad del alumno (MCA), Aunque la propuesta no es concluyente e incluso podría ser cuestionada, constituye una alternativa válida y replicable que contribuye más allá de la estructura técnica de la metodología didáctica al aclarar algunos aspectos inherentes a este proceso a través de la reflexión basada en los aportes teóricos de los autores citados.
Ver no siempre es creer: el uso juvenil de Instagram como canal de información y noticias falsas sobre COVID-19
Authors: Tarullo Raquel , Frezzotti Yanina
Published: August 2021

Durante la pandemia por COVID-19 se incrementó la circulación de contenidos informativos y desinformativos, a la vez que se profundizó el uso de las redes sociales como fuentes de información. En este contexto, la siguiente investigación aplicó encuestas digitales (N=349) a estudiantes universitarios/as del centro de la Argentina con el objetivo de conocer sus consumos noticiosos, actitudes y percepciones en relación a los contenidos sobre COVID-19 que circulan en Instagram. Los resultados mostraron que, en su mayoría, la juventud estudiada mantiene una actitud crítica frente a la información: accede a las noticias por varios canales, confía poco, contrasta bastante y se siente con herramientas para reconocer noticias falsas.

Authors: Pardhi Seema , Sharma R.K. , Kushwah S.S. , Gallani Roshan
Published: August 2021

Background: Cowpea is one of the most important leguminous vegetable crops. It has a unique ability of biological nitrogen fixation and mobilization of insoluble soil nutrient and bringing qualitative changes in soil. The basic concept of integrated nutrient management system is to maintain of plant nutrients supply to achieve a good level of crop production by optimizing the benefits from all possible sources of plant nutrients in an integrated manner, appropriate to each farming system. Considering these aspects, a field experiment was conducted to boost up productivity of cowpea seed. Methods: A field experiment was carried out during Rabi season, 2015-16 at Research Field of the Department of Vegetable Science, College of Horticulture, Mandsaur (Madhya Pradesh). The experiment was arranged in factorial randomized block design with twenty treatment combinations comprising four cowpea varieties, viz. V1-Pusa Sukomal, V2-Kashi Unnati, V3-Kashi Kanchan and V4-Kashi Shyamal and five integrated nutrient management (INM) practices, viz. N1-Vermicompost 2.5t + Rhizobium (10g/kg seeds) + PSB (10 g/kg seeds) + N (0 kg) + P2O5 (90 kg) + K2O (70 kg)/ha; N2 -Vermicompost 2.5t + Rhizobium (10 g/kg seeds) + PSB (10 g/kg seeds) + N (15kg) + P2O5 (90kg) + K2O (70 kg)/ha; N3 -Vermicompost 2.5t + Rhizobium (10 g/kg seeds) + PSB (10 g/kg seeds) + N (20 kg) + P2O5 (90 kg) + K2O (70 kg)/ha; N4 -Vermicompost 2.5 t + Rhizobium (10 g/kg of seeds) +PSB (10 g/kg seeds) + N (25 kg) + P2O5 (90 kg) + K2O (70 kg)/ha and N5-Vermicompost 2.5 t + Rhizobium (10 g/kg seeds) + PSB (10 g/kg seeds) + N (30 kg) + P2O5 (90 kg) + K2O (70 kg)/ha. Result: In present experiment the cowpea variety V1-Pusa Sukomal recorded superior performance for growth attributes, yield and yield attributes and quality attributes. This variety had taken minimum days to first flowering, days to 50% flowering and days to harvesting. Among the nutrient levels, application of Vermicompost 2.5 t + Rhizobium (10 g/kg seeds) + PSB (10 g/kg seeds) + N (30 kg) + P2O5 (90 kg) + K2O (70 kg)/ha resulted in the highest growth parameters, yield and yield parameters of cowpea seed.
Arquitectura, territorio y gubernamentalidad
Authors: Medero Santiago
Published: August 2021

En las primeras décadas de independencia del país, no existía la arquitectura como profesión moderna y sus saberes estaban dispersos en diversas ocupaciones y tradiciones. Se sostiene aquí que el proceso de profesionalización en clave nacional estuvo íntimamente asociado al control territorial centralizado por parte del Estado que se consolidó tras la última gran guerra civil, en 1904. Asimismo, se conceptualiza tanto a la profesión arquitectónica como al Estado como un proceso de construcción continuo que tiene como finalidad el gobierno (gubernamentalidad en la concepción de Foucault). En ese sentido, la arquitectura ofreció al Estado una serie de herramientas disciplinares que conformaron el sentido de su jurisdicción profesional y la distinguieron de otros saberes y ocupaciones.

La realización de los hospitales públicos en el interior de la república en las primeras décadas del siglo XX muestra todos estos procesos y aún más: evidencia que el sistema de profesiones no solamente estaba regulado por la lucha jurisdiccional, sino que también poseía un importante grado de complementariedad. En efecto, medicina y arquitectura, fueron parte de una alianza que se construyó como parte del mismo proceso de gubernamentalidad llevado a cabo por la Asistencia Pública Nacional a partir de 1910.
Helenismo na patrística
Authors: Zukowski Jean Carlos , Alexandre Lucas Gracioto
Published: August 2021

As filosofias helênicas tiveram larga influência no mundo greco-romano. Teólogos da era patrística são um exemplo desse alcance helenístico até mesmo na teologia da igreja cristã primitiva. Orígenes, teólogo cristão do terceiro século, em seus escritos, apresenta conceitos ontológicos helenistas, que podem ser vistos na teologia oriental depois dele. O objetivo deste estudo é analisar a influência do epicurismo e o estoicismo, duas escolas filosóficas do helenismo, na visão de Deus de Orígenes e sua implicação na contemporaneidade. Para o desenvolvimento do presente trabalho foi utilizado o método de análise bibliográfica. Dentre os autores pesquisados destaca-se Geovanne Reale e Justo González. A pesquisa conclui que Orígenes foi influenciado pelo neoplatonismo, a filosofia corrente em Alexandria na sua época, sistematizada com bases estoicas. O neoplatonismo posteriormente influenciou Agostinho, e a teologia cristã latina medieval e atual.
questão soteriológica na Torá
Authors: Carvalho Leite Eliathan , Pereira Corrêa Josué
Published: August 2021

Na teologia, o termo soteriologia é utilizado para designar o estudo da salvação. Além disso, há diversos outros contextos que se relacionam com a área, como o secular e o político; o que atribui uma natureza ampla ao estudo do tema. Tendo em mente essa abrangência, potencialmente vasta, o presente estudo circunscreve-se a analisar, sem pretensões de apresentar uma pesquisa exaustiva, como o tema da soteriologia é definido e apresentado nos cinco primeiros livros da Bíblia, tendo em conta a sua importância para o desenvolvimento da concepção soteriológica do restante das Escrituras e para a teologia como um todo. Para tal, foi realizada uma análise das ocorrências de palavras e expressões do campo semântico da soteriologia em cada um dos livros que compõem a Torá, tomando como base os descritores expostos por Blazen. Trata-se, portanto, de uma pesquisa de análise documental, baseando-se nos conceitos extraídos de uma prévia revisão bibliográfica. Por meio deste estudo, concluiu-se que os primeiros cinco livros da Bíblia propõem um desenvolvimento teológico linear e progressivo sobre o tema soteriológico, e que cada um deles lida com um ou mais conceitos internos da área, variando a ênfase conforme a intenção do livro.
Análise missiológica de Atos 1:4-8
Authors: Xavier Erico Tadeu
Published: August 2021

O livro de Atos dos Apóstolos relata o cumprimento da promessa de Jesus de dar poder aos apóstolos para serem Suas testemunhas na Terra. O texto de Atos 1:4-8 é analisado neste trabalho numa perspectiva missiológica com o objetivo de reconhecer algumas aplicações significativas do cumprimento da promessa de crescimento e expansão da sua igreja como missão confiada aos seus seguidores. Verifica-se que a expansão da igreja cristã foi possível em virtude da ação do Espírito Santo sobre os discípulos e fiéis que se colocaram como testemunhas de Cristo, mesmo diante da perseguição e martírio. Os discípulos de hoje são chamados a experimentarem o poder do Espírito para dar continuidade ao crescimento da fé cristã pela proclamação do Reino de Deus e o breve retorno de Cristo a todos os povos, de modo que a mensagem de salvação chegue até aos confins da Terra.
Os novos e velhos problemas do “Novo Fundeb”: análise da Emenda Constitucional 108/2020
Authors: Souza Fábio Araujo
Published: August 2021

This article brings a research whose method is based on historical materialism and dialectic and aims to exhaust the determinations of the object of analysis revealing its pseudo-concreticity until reaching its essence. The proposal of the New Fundeb, promulgated in the National Congress (EC 108/20), presents itself as a panacea for the ills of financing basic education in the country. However, the problems of Fundeb created by EC 53/06 are accentuated with the new EC 108/20. The capitalization of public basic education has found fertile ground in the new permanent funding mechanism. Among the most questionable elements are: the mercantile logic in the distribution of the ICMS (municipal tax) and the complementation of Fundeb (2.5%); the centrality in the elevation of the learning indexes – that can generate unfair dispute between networks with greater availability of resources and those with less; the consolidation of the meritocracy and of possible frauds in the indicators; the impracticability of the CAQ in face of the not generous complementation of the entity that collects more taxes in the country. Although filled with progressive terms, from a practical point of view, the New Fundeb will probably not universalize with quality the Brazilian basic education, as it happened with its predecessor.

Introduction The COVID-19 pandemic has led to various interruptions in the implementation of healthcare services provided by hospitals. Aim The aim of this study was to evaluate the staff absenteeism during the COVID-19 pandemic at Wiktor Dega Orthopedic and Rehabilitation Clinical Hospital in Poznań as well as to present the standard of providing the healthcare services assigned to the Hospital under the contract with the National Health Fund. Material and methods Work attendance of more than 700 hospital employees at Wiktor Dega Orthopedic and Rehabilitation Clinical Hospital in Poznań was evaluated. The assessment of the number of medical services that were provided during the study time was based on monthly reports prepared for the national payer of health services. A retrospective analysis covered the period of JanuaryApril 2019 and January-April 2020. Results In the months of March and April 2020, a significant increase in staff absenteeism was reported. An evaluation of the relative values of the implementation rate of medical services for the months January-April of 2019 and 2020 showed that in April 2020, there was a substantial reduction (10%) in the implementation rate of medical services on orthopaedic wards, while on rehabilitation wards, the reduction in the implementation rate started in March 2020 and was also reported in April 2020 (6%). Conclusions The COVID-19 pandemic resulted in higher staff absenteeism rates in various professional groups working in our hospital. A reduction in the performance of healthcare procedures in our hospital, both orthopaedic and rehabilitation, will lead to a re-analysis of costs and will result in applying economizing mechanisms. Keywords:COVID-19, hospitals, health services, absenteeism, healthcare, hospital employees.

Air pollution is one of the main issues faced by urban areas. Therefore, morphological characteristic and colony coverage of lichen growing at different scale air-polluted area could become as a bioindicator of their air quality. This research aims to determine the condition of lichen in spots located at near and far from the main road (width ± 29 meter) in urban area at Banjarbaru town. This research used descriptive method with purposive sampling technique. Sample were obtained from 2 plots those were far and near the main road, each plot represented by samples from 5 different trees (densed canopy with minimum DBH at 25 cm). Lichens were taken at 50-150 cm above ground level using 20x20 cm quadrant plastic frame. Observation variables include the number and shape of colonies, color and type of thallus, and percentage of thallus cover. We determined 13 colonies from spots far from the main road (500-600 meter from main road). Lichen dominated by green to bluish color, thallus consist of crustose and foliose, and the average percentage of thallus cover was 28.01%. While from that near the main road (14-250 meter from main road), we determined 14 colonies predominantly consisted of white crustose lichens, and the average percentage of thallus cover was 10.01%. Traffic intensity showed to have significant effect on lichens community. The main difference can be seen from morphology and colony coverage. Based on this result, lichen can be used as bioindicator of air quality, especially air pollution caused by motorized vehicles. Keywords arboretum, crustose, foliose, pollution, thallus
Characterizations of Graded Rings Over Which Every Graded Semi-primary Ideal is Graded 1-absorbing Primary

Published: August 2021

Let $G$ be a group with identity $e$ and $R$ be a commutative $G$-graded ring with nonzero unity $1$. Graded semi-primary and graded $1$-absorbing primary ideals have been investigated and examined by several authors as generalizations of graded primary ideals. However, these three concepts are different. In this article, we characterize graded rings over which every graded semi-primary ideal is graded $1$-absorbing primary and graded rings over which every graded $1$-absorbing primary ideal is graded primary.

Published: August 2021

Appropriate supplementation of vitamin D can affect infections, allergy, and mental and behavioral development. This study aimed to assess the effectiveness of monitored vitamin D supplementation in a population of preterm infants. 109 preterm infants (24 0/7–32 6/7 weeks of gestation) were randomized to receive 500 IU vitamin D standard therapy (n=55; approximately 800-1000 IU from combined sources) or monitored therapy (n=54; with an option of dose modification). 25(OH)D concentrations were measured at birth, 4 weeks of age, and 35, 40, and 52±2 weeks of post-conceptional age (PCA). Vitamin D supplementation was discontinued in 23% of infants subjected to standard treatment due to increased potentially toxic 25(OH)D concentrations (>90 ng/mL) at 40 weeks of PCA. A significantly higher infants’ percentage in the monitored group had safe vitamin D levels (20–80 ng/mL) at 52 weeks of PCA (p=0.017). We observed increased vitamin D levels and abnormal ultrasound findings in five infants. Biochemical markers of vitamin D toxicity were observed in two patients at 52 weeks of PCA in the control group. Inadequate and excessive amounts of vitamin D can lead to serious health problems. Supplementation with 800–1000 IU of vitamin D prevents deficiency and should be monitored to avoid overdose.
Advances and Milestones of Radish Breeding: An Update
Authors: Kumar Anand , Kaushik Prashant
Published: August 2021

Radish is an annual herbaceous root crop, fruit, and oil crop plant belonging to the Cruciferae family. The important traits for radish breeding include high yield, early maturity, late bolting, pungency, cold-hardiness, drought resistance, heat tolerance, and soil adaptability. For successful radish production, need to the understand nature and behavior of the flower, and very important to identify the S haplotypes of parental lines to produce F1 hybrids based on self-incompatibility to get rid of laborious hand emasculation in radish. In radish some desirable genes are not present within varieties. Therefore, further breeding programmes depend on inter-specific and intra-specific hybridization, which has a vital role in genomic studies and crop improvement by introducing desirable agronomic characters. It is essential to acquire detailed genetic information on chromosomes and information on inheritance. Genomics is now at the core of crop improvement, and radish crop is exploited to study the underlying differences in genotypes. But some monogenic characters are improved by genetic engineering. A three-decade span following the first documented instance of genetic engineering has witnessed its application's unprecedented growth. Researchers have successfully produced transgenic radishes with various agronomic characteristics over the last decade.
Permanent magnet generator with axial magnetic flow for wind plants
Authors: Grebenikov Viktor , Gamaliia Rostyslav , Popkov Vladimir
Published: August 2021

The results of numerical and experimental studies of an electric generator with permanent magnets and axial magnetic flux for low-power wind turbines are presented. In order for wind turbines to successfully compete with sources of autonomous power supply based on solar energy, it is necessary to reduce the specific cost of electric generators. One of the possible ways to reduce the cost of a wind turbine is to replace a quiet-running multi-pole generator with a high-speed one, which is paired with a magnetic step-up gear. In this case, the electric generator can be designed for rotation frequency n = 1000 ÷ 3000 rpm. It is for this range of rotational speed that the optimal configuration and dimensions of the magnetic system of the electric generator have been determined, at which the maximum power value is reached. Comparisons of the calculated and experimental characteristics of the generator are carried out, the good coincidence of which confirms the adequacy of the developed mathematical models. These computer models are then used to study the dependence of the specific power of the generator on the height of the stator slots and the section of the winding wire made of copper tape. It is shown that for optimal geometrical parameters the magnetomotive force of the stator winding must be matched with the magnetomotive force of permanent magnets. Only for a certain range of slot heights is the maximum power at the rated current ensured. The characteristics of the investigated generators were calculated using the Simcenter MagNet software package.
Smoking Cessation Initiatives in Total Joint Arthroplasty

Published: August 2021

» As smoking increases the risk of adverse events and leads to increased hospital costs following total joint arthroplasty (TJA), many institutions have introduced perioperative smoking cessation initiatives. Although such programs have been demonstrated to improve outcomes for smokers undergoing TJA, the optimal approach, duration, and timing of smoking cessation models have not been well-defined.

» Overall, initiating a smoking cessation program 4 weeks preoperatively is likely adequate to provide clinically meaningful reductions in postoperative complications for smokers following TJA, although longer periods of cessation should be encouraged if feasible.

» Patients brought in for emergency surgical treatment who cannot participate in a preoperative intervention may still benefit from an intervention instituted in the immediate postoperative period.

» Cotinine testing may provide some benefit for encouraging successful smoking cessation and validating self-reported smoking status, although its utility is limited by its short half-life. Further study is needed to determine the value of other measures of cessation such as carbon monoxide breath testing.

» Smoking cessation programs instituted prior to TJA have been demonstrated to be cost-effective over both the short and long term.

As we approach the era of quantum advantage, when quantum computers (QCs) can outperform any classical computer on particular tasks, there remains the difficult challenge of how to validate their performance. While algorithmic success can be easily verified in some instances such as number factoring or oracular algorithms, these approaches only provide pass/fail information for a single QC. On the other hand, a comparison between different QCs on the same arbitrary circuit provides a lower-bound for generic validation: a quantum computation is only as valid as the agreement between the results produced on different QCs. Such an approach is also at the heart of evaluating metrological standards such as disparate atomic clocks. In this paper, we report a cross-platform QC comparison using randomized and correlated measurements that results in a wealth of information on the QC systems. We execute several quantum circuits on widely different physical QC platforms and analyze the cross-platform fidelities.

Background: Tai Chi Chuan (TCC) is one effective method used to delay cognitive decline in older adults. However, the relationship between the long-term practice of TCC and the crucial working memory updating function of the brain in the elderly has not been comprehensively researched.Objective: This cross-sectional study explores how behavioral performance in a laboratory setting is related to long term practice of TCC on the updating function in older people using reaction times (RTs) of N-back tasks. Methods: 26 healthy elderly people participated in this experiment. According to the length of time TCC was practiced, 13 subjects in the TCC group had more than 5 years’ experience of TCC exercise, and 13 elderly subjects who had not been systematically exposed to mind-body exercise were assigned to the novice group. The N-back task was administered to every participant to evaluate the updating function. Results: The TCC group had faster RTs compared to the novice group (p<0.05); For the 1-back task, the TCC group showed faster RTs than the novice group. For the 2-back task, the novice group exhibited faster RTs than the TCC group. Conclusions: TCC experts exhibit greater updating function as compared to TCC novices. Long-term TCC appears to be positive associated with the updating function of older adults, making it an effective exercise to maintain cognitive function in the elderly.

BackgroundAmphora coffeaeformis, a unicellular diatom, can accumulate large amounts of lipids under nitrogen (N) limitation, because of which it can act as a promising raw material for biodiesel production. However, the molecular mechanism underlying lipid accumulation in A. coffeaeformis remains unknown. ResultsIn this study, we investigated the mechanism underlying lipid accumulation under N deprivation conditions in A. coffeaeformis using RNA-seq. The results showed that the total lipid (TL) content of A. coffeaeformis in normal f/2 medium was 28.22% (TL/DW), which increased to 44.05% after 5 days of N deprivation, while the neutral lipid triacylglycerol (TAG) content increased from 10.41% (TAG/DW) to 25.21%. The transcriptional profile showed that 591 genes were up-regulated, with false discovery rate cutoff of 0.1%, and 1,021 genes were down-regulated, indicating that N deprivation induced wide-ranging reprogramming of regulation, and that most physiological activities were repressed. In addition, ribosome biogenesis, carbon fixation, and photosynthesis in A. coffeaeformis were considerably affected by N deprivation. ConclusionsIn summary, the findings shed light on the molecular mechanisms of neutral lipid accumulation and revealed the key genes involved in lipid metabolism in A. coffeaeformis, which will be useful in designing strategies for improving microalgal biodiesel production.

Cropland displacement is a worldwide land-use phenomenon that involves replacing cropland occupied by urbanization with newly developed cropland in remote areas. Large-scale cropland displacement to some extent helps secure food supply to the growing urban population but also drives a great need for grain transport, which leads to rising energy consumption and carbon emission. Here we show a systematic evaluation of the carbon emission associated with grain transport at the prefecture-level in China in 1990 and 2015. We found that the total emission of grain transport in China more than doubled from 4.46 million-ton to 10.73 million-ton during this period. Cropland displacement contributed more than 60% of the increased carbon emission, while dietary change and population growth contributed 31.7% and 16.6%, respectively. In contrast, improvement of transport infrastructures offset 0.54 million-ton of the increased emission. Based on the research results, we provide policy suggestions on reducing grain transport carbon emission in China in terms of land use planning, grain-based value chain, as well as transport development.

BackgroundTriple-negative breast cancers (TNBCs) patients showed poor survival outcomes due to chemoresistance, and the development of new therapeutic strategies is urgently needed. The development of cancer is mainly related to chronic inflammation. Therefore, the pharmacological reduction of inflammation by natural extract components may promote anti-cancer activity and increase chemosensitivity. Snail mucus has been reported to possess the ability against inflammation, a process closely related to tumorigenesis, suggesting a potential anti-cancer function. The direct cytotoxic activity of snail mucus in cancer cells was investigated in this study.Methods The effect of snail mucus on cell viability in breast cancer cells and normal epithelial cells were measured by MTT and IncuCyte Live-cell analysis. The active fractions of snail mucus were isolation by performing MPLC and the anti-cancer ingredients were identified by NMR spectrometer analysis.Results Snail mucus significantly decreased the proliferation and viability of TNBC cells with relatively lower cytotoxicity to normal breast epithelial cells and enhanced their response to chemotherapy. Mechanistically, snail mucus induces an extrinsic apoptotic pathway through activation of Fas signaling by suppressing nucleolin. Two possible peptide fractions have also been identified as the anti-cancer ingredients of the snail mucus.ConclusionsIn summary, snail mucus can induce programmed cell death via the extrinsic apoptotic pathway and might have therapeutic potential with chemo-sensitizing effect for TNBCs.

Fish associated microorganisms are known to be affected by the environment and other external factors, such as microbial transfer between interacting partners. One of the most iconic mutualistic interactions on coral reefs are the cleaning interactions between cleanerfishes and their clients, during which direct physical contact occurs. Here, we characterized the skin bacteria of the Caribbean cleaner sharknose goby, Elacatinus evelynae, in four coral reefs of the US Virgin Islands using sequencing of the V4 region of the 16S rRNA gene. We specifically tested the relationship between gobies’ level of interaction with clients and skin microbiota diversity and composition. Our results showed differences in microbial alpha- and beta-diversity in the skin of gobies from different reef habitats and high inter-individual variation in microbiota diversity and structure. Overall, the results showed that fish-to-fish direct contact and specifically, access to a diverse clientele, influences the bacterial diversity and structure of cleaner gobies’ skin. Because of their frequent contact with clients, and therefore, high potential for microbial exchange, cleanerfish may serve as models in future studies aiming to understand the role of social microbial transfer in reef fish communities.

We report a series of 13 patients with COVID-19 treated with Cacipliq20®, an heparan sulfate mimetic approved for the treatment of hard to heal cutaneous ulcers. Heparan sulfates play important roles in tissue repair and possess antiviral activity. Cacipliq20® was administered through nebulization at a dose of 45 mg twice a day for 5.5 consecutive days. All patients presented respiratory symptoms with some dyspnea and in most cases pulmonary abnormalities on chest CT-Scan. Eight patients presented with a moderate form of the disease, three patients with a severe form, one with a mild form, and one with a critical form. In all patients the treatment was added to the standard of care. Ten patients were treated during the acute stage of the disease (<4 weeks from symptoms onset) while 3 patients were in the post-acute stage (>4 weeks from symptoms onset). A second treatment was administered for another 5.5 days in 6 patients. All patients showed clinically improvement after treatment. The time to first improvement ranged from 2 to 4 days after first treatment onset with a median of 3 days. Time to full clinical recovery ranged between 6 to 27 days from treatment onset with a median of 6 days. Lung CT scans followed clinical impression and showed a clear improvement of the lesions in most cases. The treatment was well tolerated in all patients. These preliminary observations should justify further evaluation through a well-designed placebo-controlled therapeutic trial.

BackgroundIn rare diseases, only a low number of regionally distributed experts are available in medical care. The health service platform for rare diseases (www.se-atlas.de) provides a search for health care providers and patient organisations in Germany for specific rare diseases and presents the results to patients or physicians. The objective of this study was to examine the background and purpose, user satisfaction and usability when using se-atlas and to receive suggestions on improvements for implementation in the next release of se-atlas. MethodsWe conducted an online survey over a total period of five weeks between December 2020 and January 2021. Participants were members of patient organisations of rare diseases and experts of rare diseases centres in Germany. The questionnaire addressed the objectives of this study in 10 questions. We used Likert scales (4 to 6 points), as well as the System Usability Scale to measure usability (range: 0 to 100). The data obtained from the survey was analysed descriptively. ResultsIn total, 55 participants completed the survey (16 experts and 39 members of patient organisations). The results demonstrate that users know se-atlas mainly through patient organisations and the German National Action League for People with Rare Diseases. Furthermore, the experts use se-atlas more frequently than members of patient organisations do. Regarding to user satisfaction, participants were satisfied when using se-atlas (scale 1-6, mean = 4.31, SD = 1.18). They rated se-atlas functions with an average between 3.82 and 4.4 (scale 1-6). Additionally, se-atlas functions were considered as important with an average between 3.11 and 3.75 (scale 1-4). With regard to usability, the website was rated with an overall SUS score of 67.1, whereas the results differ between the participants group (experts = 76.1, patient organisations = 63.1). Moreover, participants made suggestions, e.g. that more disease entries should be available and usability can be improved. ConclusionsThis study involved experts and members of patient organisations to assess the background and purpose, user satisfaction and usability when using se-atlas. Despite the promising results and first new implementations, further optimisations of the platform in terms of usability and various functionalities are necessary.
