Con la construcción de la estación de Trindade se crearía una nueva plaza. El acceso a esta estación se realiza desde ésta. La cubrición de la Estación de Superficie es una plataforma accesible a los peatones que une la Rua de Camões a la Rua Alferes Malheiro y a una travesía de mismo nombre. Se prevé a lo largo de de Jornal de Notícias una galería metálica que hará de puente entre Rua Gonçalo Cristóvão y la Travessa Alferes Malheiro. También una nueva calle peatonal en la parte posterior de la estación unida mediante un ascensor a la travesía con la Rua Alferes Malheiro. Este acceso ofrece también la conexión con la cubrición y la estación de la línea S. Se propuso rediseñar el bloque enmarcado por las calles de Fernandes Thomas, Trinidad, y Ensign Malheiro Bonjardim con nuevos edificios y la restauración de los ya existentes. Todo el interior de este parque sería un aparcamiento que sustituiría al actual.

En España el consumo energético en edificación supone el 20% del consumo de energía final, representando la climatizaciónun 40% del mismo. Uno de los objetivos generales del CTE es reducir este consumo energético de las viviendas. Asimismo, enel caso particular de su DB-HS3 uno de los objetivos es garantizar unos caudales de ventilación mínimos. El equilibrio entreambos supone un importante reto tecnológico necesario de abordar. La búsqueda de este equilibrio supone obtener la mejorcalidad de aire con el mínimo consumo energético, mediante una ventilación eficiente y eficaz, que responda adecuadamente a CUÁNDO, DÓNDE y CUÁNTO.
El conocimiento arquitectónico en la era de la información: los repositorios digitales
Authors: Madrazo Leandro
Published: October 2022

La arquitectura, al igual que otras disciplinas, aspira a delimitar su ámbito de estudio identificando y nombrando, definiendo y clasificando los objetos –conceptuales y materiales– que le son propios. Sin embargo, a diferencia de las ciencias de la naturaleza, el objeto de estudio de la arquitectura se encuentra en sus propias creaciones: en las edificaciones que conforman el entorno construido, y en los procesos de proyecto y de construcción que las preceden. Por tanto, indagar acerca de lo que constituye la arquitectura comporta no solo analizar proyectos y edificios, sino también comprender los vínculos entre ambos.
Disminución de la probabilidad de atascos por la presencia de un obstáculo cerca de la salida
Authors: Lozano Celia , Janda Álvaro , Maza Diego , Garcimartín Angel , Zuriguel Iker
Published: October 2022

Los medios granulados –materia inerte compuesta por sólidos divididos– al pasar por una abertura que sea sólo un poco mayor al tamaño de las partículas se pueden atascar. Se ha estudiado como disminuye la probabilidad de que este sistema se atasque gracias a la colocación de un obstáculo delante de la salida. El resultado obtenido demuestra que se disminuye la probabilidad de atasco dependiendo dónde esté colocado el obstáculo, siendo una posición óptima donde la distancia entre el obstáculo y la salida es similar al tamaño de la abertura. Estos resultados pueden ser interesantes para el diseño óptimo de una salida de evacuación.

Published: October 2022

Convertir en extensible una superficie de doble curvatura puede plantear problemas de difícil solución. Incluso en ocasiones una superficie así puede no ser extensible. En el caso de este proyecto la extensibilidad se consigue mediante una geometría muy precisa aplicada a una superficie que no es exactamente esférica.
Edificio de viviendas en Sarriguren
Authors: Capilla-Frías Conrado , Vallejo-Lobete José V.
Published: October 2022

El trazado definitivo de Sarriguren tiene un carácter híbrido. Desde su origen, concebido simultáneamente con ambición por el hecho urbano, ilusión por la sostenibilidad, ha evolucionado -quizás inevitablemente- hacía lo pragmático y convencional. De este modo el asentamiento de Sarriguren al fin se ha visto rodeado por edificaciones con un trazado y una imagen que le son extraños. Dentro de ese contexto este edificio se sitúa en un lugar privilegiado, entre el pueblo de Sarriguren y el lago, de modo que conformará parcialmente la imagen desde el norte del nuevo Sarriguren.

Rascacielos bioclimático - Aprendiendo de Bawa
Authors: Beng-Kiang Tan , Robson David
Published: October 2022

Este documento describe el que se considera uno de los primeros edificios de oficinas bioclimáticos diseñado para tener iluminación y ventilación natural y expone lecciones para la práctica. El Edificio State Mortgage Bank de 12 plantas (conocido ahora como Edificio Mahaweli) en Colombo, Sri Lanka, diseñado por el fallecido arquitecto asiático Geoffrey Bawa en 1972,incorporó muchos principios de diseño receptivos al medio ambiente mucho antes de que las palabras bioclimático y arquitectura sostenible se convirtieran en frecuentes. Describe el entorno y el contexto para el cual se diseñó el proyecto y sus principios de diseño y estrategias eficaces de energía pasiva. También discute si estos principios y estrategias se pueden aplicar todavía en el diseño de bloques de oficinas bioclimáticos en nuestros días. Los autores han entrevistado a los miembros del equipo de diseño original, han recopilado material de los archivos de Bawa, han investigado las condiciones actuales y las pautas de uso del edificio, han entrevistado a los usuarios del edificio y han construido un modelo del edificio en 3D por ordenador.

Authors: Sosa Edgar , Vargas-Huertas William , Fernández Diego Andrés
Published: October 2022

Este estudio describe las prácticas docentes mediadas por TIC durante la situación de emergencia originada por el COVID-19 en el primer semestre de 2020 en colegios oficiales de Bogotá-Colombia y determina la relación entre variables sociodemográficas y las relacionadas con la pandemia.  Se efectuó a través de un diseño metodológico cuantitativo con alcance descriptivo y correlacional con una muestra de 113 docentes, quienes en su mayoría utilizaron entre dos y tres alternativas para seguir con sus clases, entre las que se destacan las tareas por mail o WhatsApp, video o audios grabados, uso de plataformas educativas y videoconferencias. Los docentes más jóvenes percibieron la experiencia de usar las TIC como buena y excelente, en comparación con los de mayor edad, quienes la calificaron como regular y mala.  De igual manera, los docentes con menos años (biológicos y de experiencia) manifestaron diferencias entre el proceso de evaluación antes y durante la pandemia. Con relación a la periodicidad de contacto con los estudiantes, esta fue mayor en los niveles de preescolar y primaria vs. Los de secundaria y media. Finalmente, los resultados evidenciaron que los docentes reconfiguraron sus prácticas y las TIC fue el mediador de estas.
TIPOS DE INTERACCIONES EN FACEBOOK A PARTIR DE UN EJERCICIO DE EDUCACIÓN INFORMAL APOYADO EN RETOS MATEMÁTICOS
Authors: Garzón-Bermúdez Wilson Fernando , Cortés-Escobar Lady Milena
Published: October 2022

Las posibilidades que dan las aplicaciones web y su uso masivo desde gran cantidad de dispositivos electrónicos recrean nuevos espacios y dinámicas en el ámbito educativo, entendido éste más allá de los procesos escolares formales. Cada vez es más difusa la brecha entre la educación formal y la informal, profundizadas por  las aceleradas transformaciones curriculares acarreadas por metodologías remotas. En un intento de incorporar las facilidades de los dispositivos electrónicos en la gestión organizacional y del conocimiento, las instituciones escolares integran paquetes Learning Management Systems con evidentes falencias en el aspecto social.  Desde allí surge la aplicación de la teoría conectivista en el ámbito educativo, potencializada por la web 2.0, lo que brinda una perspectiva educativa fundamentada en lo espontáneo, caótico, informal y complejo, que sucede en las redes de individuos.  Estos enlaces son la metáfora de las interacciones que se presentan en complejos procesos comunicativos mediados por las TIC.

La presente investigación se aborda desde el paradigma hermenéutico cualitativo. El estudio contó con la participación voluntaria de los sujetos inscritos en un grupo en Facebook, en el marco de una propuesta educativa informal. Los procesos se enmarcaron en una inmersión, actuación docente, una observación constante de las interacciones y una entrevista a algunos participantes seleccionados en un muestreo por criterios. Se triangularon los datos emergiendo varios tipos de interacción (dirección, temática, propósito, extensión y formato)  relacionados significativamente con la actuación del investigador que se presentó como docente y las publicaciones que este realiza. Se determinó que hay una relación entre los elementos, lo que llevó a proponer una escala multilineal para estimar el nivel de interacción de los mensajes. Además de ello, se vislumbró la importancia de la participación del docente en el tipo de interacciones del grupo.

Authors: Benítez-Chará Willington , Saldarriaga-Salazar María Eugenia
Published: October 2022

En tiempo de COVID-19 los desafíos enfrentados por los docentes han sido numerosos, se evidenció inequidad y falta de preparación del sistema educativo para responder a retos fuera del aula. Como consecuencia, el grupo de investigación Historeo adelantó el estudio macro “La Educación en tiempo de COVID-19”, que surgió de reflexiones pedagógicas de maestros al interior del aula. En este marco, se realizó la investigación con docentes de la Institución Educativa César Negret Velasco de Popayán, cuyo objetivo fue identificar desafíos de los docentes, a través de sus vivencias en el proceso de enseñanza-aprendizaje en tiempo de COVID-19. Es una institución pública con 525 estudiantes para quienes el cambio en la educación y las condiciones socioeconómicas fueron difíciles y del cual se da cuenta en el presente escrito. La metodología fue exploratoria e identificó conceptos, dejó validar relaciones, hechos, entre otros. Además, se recolectó información con encuestas aplicadas a cinco docentes de matemáticas, y 178 estudiantes de los grados sexto a undécimo, para lo cual se definieron 4 desafíos: formación y experiencia en manejo de Tics como docente; actividades realizadas que dan continuidad al aprendizaje; problemas encontrados en educación desde casa y relación con el otro. En resultados: los docentes reconocen falta de competencias para manejo de tics, se procura una buena comunicación en la formación, buscan recursos didácticos acorde a necesidades. Identifican problemas como: apoyo a familias, la salud mental de menores en aislamiento y evaluación académica. La relación con la comunidad educativa en fundamental. Como conclusiones: unen educación presencial y virtual para obtener el modelo “educación en casa”, evidencian falta de competencias digitales para docentes y estudiantes, la enseñanza y aprendizaje de matemáticas se permea por el uso de Tics aunque, evidencian brechas tecnológicas y sociales que demuestran urgente intervención para disminuirlas.  El acercamiento docente a estudiantes y sus familias disminuye brechas emocionales.

Published: October 2022

En este documento se realiza la descripción de la experiencia pedagógica basada en la lectura dramatizada con estudiantes de grado once, que se suscitó a través de la educación remota generada por la pandemia durante el año 2020. Esta propuesta se enmarca dentro del deseo de generar un trabajo interdisciplinar que le permitiera tanto a los estudiantes como a los docentes crear espacios de discusión con un propósito en común: la lectura de la obra literaria “Ensayo sobre la ceguera”. Se abordan las categorías: interdisciplinariedad, comprensión de lectura, pensamiento crítico y goce literario. En la sistematización se sigue el camino metodológico propuesto por Jara (2018) quien nos invita a realizarla en cinco momentos: punto de partida, plan de sistematización, recuperación del proceso vivido, reflexiones y puntos de llegada. Los hallazgos obtenidos ponen a dialogar nuestra experiencia a la luz de los constructos teóricos, para finalmente, reflexionar acerca del quehacer docente y las oportunidades en la construcción de nuevas formas de entender y relacionarse con el mundo literario.

The current understanding of the carbonation and the prediction of the carbonation rate of alkali-activated concretes is complicated inter alia by the wide range of binder chemistries used and testing conditions adopted. To overcome some of the limitations of individual studies and to identify general correlations between mix design parameters and carbonation resistance, the RILEM TC 281-CCC ‘Carbonation of Concrete with Supplementary Cementitious Materials’ Working Group 6 compiled and analysed carbonation data for alkali-activated concretes and mortars from the literature. For comparison purposes, data for blended Portland cement-based concretes with a high percentage of SCMs (≥ 66% of the binder) were also included in the database. The analysis indicates that water/CaO ratio and water/binder ratio exert an influence on the carbonation resistance of alkali-activated concretes; however, these parameters are not good indicators of the carbonation resistance when considered individually. A better indicator of the carbonation resistance of alkali-activated concretes under conditions approximating natural carbonation appears to be their water/(CaO + MgOeq + Na2Oeq + K2Oeq) ratio, where the subscript ‘eq’ indicates an equivalent amount based on molar masses. Nevertheless, this ratio can serve as approximate indicator at best, as other parameters also affect the carbonation resistance of alkali-activated concretes. In addition, the analysis of the database points to peculiarities of accelerated tests using elevated CO2 concentrations for low-Ca alkali-activated concretes, indicating that even at the relatively modest concentration of 1% CO2, accelerated testing may lead to inaccurate predictions of the carbonation resistance under natural exposure conditions.
Determination of Resmethrin in Corn Silk Matrix by Gas Chromatography-Flame Ionization Detector (GC-FID)
Authors: SERBEST Hakan
Published: October 2022

The use of pesticides provides benefits such as growing food products necessary for life, sustainability of production efficiency and prevention of diseases caused by pests. However, these benefits can turn into negative effects for humans and other living organisms with the use of pesticides in inappropriate doses and application methods. In this study, it was aimed to determine resmethrin, which belongs to the insecticide class, by gas chromatography-flame ionization detector (GC-FID) method. Hence, a suitable temperature program was utilized to determine resmethrin at a certain retention time. Limit of detection (LOD) and limit of quantification (LOQ) values were recorded as 0.02 and 0.08 mg/L under the proposed conditions, respectively. After corn silk sample was extracted using acetonitrile, analytical measurements were carried out to investigate the presence of resmethrin. There was no analytical signal detected that belonged to resmethrin in the analyzed sample. Recovery experiments were performed using external calibration method with spiked samples at three different concentrations and good percent recovery results were obtained between 93 and 97%.
An Innovative Application On Supermarket Selection Through Using Intuitionistic Fuzzy TOPSIS Method
Authors: TUĞRUL Feride
Published: October 2022

Multi-criteria decision making methods have recently attracted the attention of researchers and have had a large share in multidisciplinary fields. In this study, using the intuitionistic fuzzy TOPSIS method, supermarket chains were evaluated in the consumer context and the most preferred supermarket was determined. Consumers' opinions were expressed using linguistic term. The reason why the intuitionistic fuzzy TOPSIS method is preferred; it is the ability of consumers to express their opinions easily, to take into account the undecided situations with the help of intuitionistic fuzzy sets, and thus to create an objective decision making mechanism.
Being polite and subordinate: Morphosyntax determines the embeddability of Utterance Honorifics in Japanese
Authors: Tomioka Satoshi , Ishii Keita
Published: October 2022

Utterance Honorifics (UHs) are generally regarded as a main clause phenomenon as they reflect the speaker’s attitude towards the addressee/audience. UHs in Japanese present a challenging problem to this view, however, as it has been reported that they can be embedded under some circumstances (Miyagawa 2012; Yamada 2019 and references therein). In this paper, we closely examine the embedding patterns of the three UH markers in Japanese, the verbal UH, the UH copula for a noun, and the UH copula for an adjective, and show that there are considerable variations among the three UH markers. We argue that their distributional differences are intimately tied to their morphosyntactic characteristics and their interaction with the tense and finiteness specifications in the language. More specifically, we propose that there is a close, though possibly not perfect, correspondence between the degree of embeddability of the UH markers and the syntactic size of constituents that contain them. The proposed analysis is couched within Porter et al’s (2019) syntactic analysis of UHs which posits the UH head, c°. It will be demonstrated that the varying embeddability of the Japanese UH markers is, for the most part, consistent with Porter et al’s proposal that c° is projected only at the root level, but we identify a few exceptional cases in which some radically ‘root-like’ embedded clauses can have their own cPs. We further suggest that an embedded UH is licensed via multiple Agree from the matrix clause, which makes the Japanese UH marking a kind of concord phenomenon.
A research on the tourists’ destination selection attributes and satisfaction: Text mining and fuzzy-set qualitative comparative analysis
Authors:   The Tourism Sciences Society Of Korea, Park Ji-Won , Lee Hyung-Ryong
Published: October 2022

The purpose of this study is to add to our understanding of actual traveler interest in the tourism market by investigating the causal conditions of tourist destination attributes on tourist satisfaction. Prior to proceeding, natural tourist destinations that were recommended 5 times in a row in South Korea's top 100 must-see tourist destinations were chosen as the study's target. Seoraksan National Park, Hallasan National Park, Suncheonman Wetland (Suncheonman National Garden), Nami Island, and Udo are among them. For an analysis of the online reviews of these five well-known tourist destinations, topic modeling was used, and the latent dirichlet allocation (LDA) technique with TF-IDF weight was used to create a comprehensive list of the topics posted by Tripadvisor reviewers. Making scientific inferences about nature tourism phenomena, such as Fuzzy-set Qualitative Comparative Analysis (FsQCA), to better predict and explain real-world nature tourism phenomena using a configurational approach, is becoming more popular. The purpose of this article is to identify the key contribution and knowledge structure of tourist destination selection attributes as well as their overall satisfaction research using complexity theory and FsQCA. The primary goal of this study is to investigate not only the influence of tourist destination selection attributes as a single variable in online reviews, but also how these selection attributes influence tourist satisfaction with various combinations of causal conditions. These findings are useful in understanding individual travelers' perceptions of tourist destinations as well as their overall satisfaction.
A study on perception and attitude on wellness tourism using big data: Semantic network analysis and sentiment analysis
Authors:   The Tourism Sciences Society Of Korea, Bae So-Hyun , Lee Su-An
Published: October 2022

This study used big data to conduct text mining and sentiment analysis on individuals' perceptions and attitudes toward wellness tourism. From October 8th, 2018 to October 7th, 2021, web documents containing keywords such as 'wellness tourism' and 'wellness travel' were collected from Naver, Daum, and Google. A total of 23,770 documents were used to analyze keywords frequency, TF-IDF, N-gram, degree centrality, CONCOR, and sentiment analysis after duplicated posts and meaningless words were removed. The findings revealed that the words most frequently appearing and having high TF-IDF values were mentioned in the context of wellness tourism destination selection and development, purposes and types of wellness travel, and information on domestic wellness tourist spots. Words associated with wellness, tourism, tourism destinations, selections, and so on played critical roles in the network, according to degree centrality measures. Six clusters emerged from CONCOR analysis, including core attributes, projects, wellness tourism development, and so on. Finally, sentiment analysis revealed that people had a generally positive impression of wellness tourism. This study contributes to a better understanding of wellness tourism perceptions and aids in the development of marketing strategies to revitalize wellness tourism.

The current stage of development of the world community is characterized by an everincreasing role of the information sphere and is completely dependent on information resources and technologies, their quality and security. Computerization of all aspects of life has become the main reason that a significant part of the elements of social relations cannot be implemented without the use of new IT in various subject areas, and hence without the implementation of a reliable system of integrated security of the developed information automated systems. This article gives the concept of network traffic, considers the classification of network traffic, in which classification by port numbers, deep packet analysis, stochastic packet analysis, and the use of machine learning were identified. Methods for protecting information using trusted technologies were defined, where a general presentation of trust technologies was considered. The main conclusions are drawn on the prospects of using machine learning to classify network traffic in trusted technologies.
Estimating microbial population data from optical density v2
Authors: Yeh Pamela
Published: October 2022

The spectrophotometer has been used for decades to measure the density of bacterial populations as the turbidity expressed as optical density – OD. However, the OD alone is an unreliable metric and is only proportionately accurate to cell titers to about an OD of 0.1. The relationship between OD and cell titer depends on the configuration of the spectrophotometer, the length of the light path through the culture, the size of the bacterial cells, and the cell culture density. We demonstrate the importance of plate reader calibration to identify the exact relationship between OD and cells/mL. We use four bacterial genera and two sizes of micro-titer plates (96-well and 384-well) to show that the cell/ml per unit OD depends heavily on the bacterial cell size and plate size. We applied our calibration curve to real growth curve data and conclude the cells/mL – rather than OD – is a metric that can be used to directly compare results across experiments, labs, instruments, and species.
Gastos ambientais dependem de folga financeira? Estudo longitudinal no Brasil
Authors: Santos José Glauber Cavalcante dos , Vasconcelos Alessandra Carvalho , Mendes De Luca, Doutora Márcia Martins
Published: October 2022

Objetivo: Examinar se nas empresas brasileiras de capital aberto os gastos ambientais são influenciados pela folga financeira.

Método: A amostra reuniu 53 empresas listadas na B3, com gastos ambientais realizados no período 2008-2018, totalizando 308 observações. Além dos gastos ambientais, tratados como medida dependente, o construto folga financeira atua como medida independente, sob três enfoques (caixa e disponibilidades, fluxo de caixa operacional e capacidade de dispêndios/investimentos – KZ index). Foram feitas estimações por Pooled Ordinary Least Squares (POLS), com controle de efeitos fixos por setor e ano, além de outras medidas de controle. Empregou-se a defasagem temporal.

Resultados: Os resultados principais comprovaram que a folga financeira baseada no caixa e nas disponibilidades afeta negativamente os gastos ambientais, sendo essa relação algo persistente. Constatou-se ainda que a folga financeira baseada na medida abrangente do índice de Kaplan e Zingales (1997) afeta positivamente os gastos ambientais, sem relação de persistência.

Contribuições: A pesquisa traz implicações pertinentes para a literatura e para o contexto das empresas, ao evidenciar como a folga financeira pode interferir na predisposição da firma para realizar dispêndios de natureza ambiental. Sugere-se, assim, uma correlação entre a condição financeira da empresa e o aporte de recursos na dimensão corporativa ambiental.
Quantitative Empirical Research in Management Accounting: A Proposed Typology and Implications for Internal versus External Validity
Authors: Aguiar, Doutor Andson Braga de , Magalhães Mucci Daniel , Modolon Lima Myrna
Published: October 2022

Purpose: The purpose of this study is twofold. First, we propose a typology of quantitative empirical research in management accounting based on two design features: presence of control group and sample representativeness. Second, we discuss implications of the methods for trade-offs between internal and external validity.

Method: Based on previous methodological studies we develop a typology with eight quantitative empirical methods.

Results: Based on the two design features, we propose eight quantitative empirical methods for management accounting studies: (1) laboratory experiment, (2) crowdsourcing experiment, (3) field experiment, (4) natural experiment, (5) single entity survey, (6) proprietary archival study, (7) large-scale survey and (8) pre-structured archival study. In addition, we critically compare the trade-offs and discuss the implications of these methods for internal and external validity.

Contributions: The contribution is twofold. First, the proposed typology can help junior management accounting researchers increase the familiarity with the available empirical methods, some of which are still incipient in Brazil. Second, this study states that the choice of an empirical method typically implies benefits in terms of a validity type (e.g. internal validity) at the expense of other validity type (e.g., external validity). Claims of causality and results generalizability depend on which validity type is prioritized and remedies adopted to increase the overall validity of a study’s results.
Class backwards: linguistic racism and educational malpractice in American schooling
Authors: Baugh John
Published: October 2022

Darder’s depiction of “Linguistic Racialization”, described herein, provides the foundation for this discussion, where raciolinguistic pedagogy has perpetuated a diverse and troubling legacy of educational malpractice against underrepresented language minority students who attend underresourced public schools throughout America. Due, in part, to paradoxical educational practices with differential access to unequal educational resources, the vast majority of linguistically disenfranchised students are often overlooked, or worse, subjected to misguided educational practices that fail to reduce academic disparities that are reinforced by poverty, unequal access to fair housing, and a lack of pedagogical dexterity that might have the potential to promote improved educational outcomes. Some policy proposals conclude this discussion, which, if implemented, could potentially overcome the history of unequal academic achievement that has resulted from a combination of De Jure and De Facto educational apartheid.
Spatiotemporal Dispersal Study of Mangrove Avicennia marina and Rhizophora apiculata Propagules
Authors: Wong Yun Yun , Foong Swee Yeok , Wang Youshao , Dai Lu , Mao Limi , Goh Thian Lai
Published: October 2022

The propagule dispersal pattern of the two common mangrove species, Avicennia marina (Forsk.) Vierh. and Rhizophora apiculata Blume at a mangrove fringed coast, in the southwest tip of Penang Island was examined. Propagule dispersal study of both species were carried out by release and recapture method, while early developments of propagule were observed by an on-site tethering system. A. marina propagules recorded higher dispersal rate as compared to R. apiculata. After 60 tidal cycles, almost all propagules had moved away from the initial release site under the influence of strong wave current. The A. marina propagules were observed to grow better and faster than the R. apiculata propagules. However, the propagules of both species eventually failed to establish at the study site due to strong wave effect as well as unfavourable soil condition. A. marina and R. apiculata were found to adopt different strategies in propagule dispersal and early growth. A. marina was notably better adapted to thrive in the coastal environment. In a similar open coastal area, wave current and soil condition are suggested to be the most critical factors affecting the mangrove propagule dispersal and early establishment.
Hot Water Extract from Saccharomyces cerevisiae Scavenges DPPH and Reduces Senescence Associated b-galactosidase (SA-b-Gal) in Human Dermal Fibroblasts

Published: October 2022

Extracts from Saccharomyces cerevisiae are incorporated in a lot of cosmetic products on the market, but the benefits of the extracts lack scientific reports. We tested the toxicity and anti-senescent activity of an extract from S. cerevisiae on an in vitro model, the human dermal fibroblast (HDF) cell culture. We chronicled the development of the extraction method and the subsequent biochemical assays. We used two extraction methods which were hot water extraction and rapid spin. The optimum duration and growth phase to harvest S. cerevisiae were determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, which also proved that the extracts exhibited antioxidant activity. Hot water extract showed a higher antioxidant activity, and not toxic to HDF. When subjected to senescence-associated β-galactosidase (SA-β-Gal) assay, the hot water extract significantly reduced the expression of SA-β-Gal in pre-senescent (passage 20, 30 < population doubling < 40) and senescent (passage 30, population doubling > 50) HDF. In conclusion, S. cerevisiae hot water extract possessed antioxidant activity by scavenging DPPH, and anti-senescent activity by reducing the expression of SA-β-Gal in pre-senescent and senescent HDF.

Introduction Adduction or flexion-adduction contracture of the hip joint often causes static and dynamic impairments in children with spastic cerebral palsy that can be corrected with hip abduction orthosis. No reports confirming or rejecting the effectiveness of the method in the gait correction have not found. The objective was to explore the effect of the hip abduction orthosis on gait kinematics in children with spastic cerebral palsy. Material and methods Twelve biomechanical tests were performed for 6 patients of GMFCS level 3 (6 tests with hip abduction orthosis and 6 tests with no hip abduction orthosis). Gait analysis was produced using the Qualisys Miqus M5 motion capture system (Sweden). Clinical gait analysis was performed with PAF 2.0 of QTM software, Visual3D, Statistica 10 and Excel. Results A comparative analysis of the mean values showed differences in the gait parameters depending on test conditions. Improvements in the spatial-temporal parameters ranged between 0.4 % and 23.6 % with use of orthosis. The kinematic analysis of large joints demonstrated a slight positive effect on the hip joint function. There were no significant differences in the function of other joints. The use of orthosis improved the overall gait index score for the left and right lower limbs by 12.5 % and 5.7 %, respectively.

Introduction Bone mineral density (BMD) of the vertebrae is a critical issue before performing stabilizing interventions at the lumbar level. Determination of BMD in Hounsfield units (HU) according to CT data is a more accurate method versus to the "gold" standard – densitometry. Purpose To determine BMD of key anatomical areas of the lumbar vertebrae in HU and correlate with densitometry data. Methods A retrospective cohort of patients was studied prior to decompression and stabilization intervention at the lumbar level. The BMD of each lumbar vertebra in its different anatomical regions in HU was assessed according to CT of the lumbar spine and was compared with densitometry data. Results In the roots of the L2-S1 arch of the vertebrae, BMD was significantly higher than in the bodies of the same vertebrae (p < 0.01); in the L1 and S1 vertebrae, the difference in BMD between the body and the roots of the arch was not significant. An increase in the density of bone tissue in the vertebral bodies to the underlying levels was determined; BMD in the roots of the arch also increases, but only up to the L5 vertebra. BMD in the roots of the arch of the S1 vertebra is significantly lower than in the overlying L5 vertebra (p = 0.032). Discussion The obtained findings supplement the reported data in the current literature. The HU value is a more accurate and significant parameter of BMD, which should be considered in the practice by a spinal surgeon. Conclusions According to CT data of the lumbar spine, the BMD of L2-L5 in the arch roots is significantly higher than in the vertebral bodies. The BMD of the S1 vertebra in the arch roots is significantly lower than in the L5 vertebra. It may be the reason of high failure rate of caudal fixation at this level. Particular attention should be paid to the planning and surgical techniques in patients not only with osteoporosis but also with osteopenia. BMD findings obtained by densitometry in these conditions do not have a significant difference.

Introduction The article presents a case report and a brief literature review of an adverse event of brachial plexus injury associated with prone positioning in spinal surgery. The purpose was to report a case of bilateral brachial plexus injury after correction of Scheuermann's kyphosis. Material and methods Reported is a case of brachial plexus injury in a patient with Scheuermann's kyphosis after surgical correction. Results The patient could completely regain motor function of the left limb at 6 months with palsy scored 3 proximally retained in the right hand. Discussion The literature describes three pathophysiological conditions that predispose to brachial plexus injury in the postoperative period: sprain, compression, and ischemia. The adverse event is reversible in most cases and recovery depends on the degree of neurological deficit at an early stage. Recommendations are offered for surgeons and anesthesiologists to avoid the occurrence of the complication or take timely measures to alleviate the consequences. Conclusion Upperlimb somatosensory evoked potentials, a part of neurophysiological monitoring can be practical for prevention of the complication. Prevention of brachioplexopathy should be part of perioperative care.

Background: To describe the patient characteristics and usage pattern of biosimilar bevacizumab for the treatment of metastatic colorectal cancer (mCRC) in India.Methods: This real-world, retrospective analysis included adult patients receiving biosimilar bevacizumab between April 2021 and March 2022.Results: A total of 1125 patients with mCRC who received biosimilar bevacizumab-based chemotherapy were included. The mean age at diagnosis was 57.8 years. Majority of the patients were males (71%) and belonged to the age groups of 41-76 years. The primary tumor site was right colon (52.6%) followed by left colon (29.2%) and rectum (17.3%), and tumor grade was reported as high in most (88.7%) of the patients. Majority of the patients received biosimilar bevacizumab-based chemotherapy as first-line therapy (61.3%), followed by second-line (31.9%) and third-line therapy (6.8%). In combination with biosimilar bevacizumab, FOLFOX (folinic acid, 5-fluorouracil, and oxaliplatin) was the most commonly administered chemotherapy regimen (42.9%), followed by CAPOX (capecitabine and oxaliplatin, 26.5%) and FOLFIRI (folinic acid, 5-fluorouracil, and irinotecan, 22.8%).Conclusions: Biosimilar bevacizumab-based chemotherapy is being widely used in real‑world clinical setting in India for the management of patients with mCRC.
Efficacy of ormeloxifene in comparison to norethisterone in the management of abnormal uterine bleeding
Authors: Srinivasan Suguna
Published: October 2022

Background: Abnormal uterine bleeding (AUB) is the most common complaint worldwide. In India, most of the women present with menorrhagia and majority of them are anemic and require medical management to avoid its consequences. Hence this study is done to compare the efficacy of ormeloxifene with norethisterone in women presenting with AUB.Methods: In this study 61 women suffering from AUB were included. This prospective randomized double blinded study was done on women between the age group of 19-45 years and were allocated randomly into two groups, one group was given ormeloxifene and the other was given norethisterone for a period of 3 months. Haemoglobin levels, endometrial morphology on ultrasound were assessed before and after the treatment in both the groups.Results: It is observed in our study, that both ormeloxifene and norethisterone reduced menorrhagia. The rise in hemoglobin concentration was significantly more with ormeloxifene than norethisterone (8.3 g/dl to 10.3 g/dl versus 9.0 g/dl to 10.4 g/dl). In our study, the significant reduction in the endometrial morphology was more with ormeloxifene than norethisterone (9.3 mm to 7.8 mm versus 8.3 mm to 7.2 mm).Conclusions: Ormeloxifene is a new modality drug and is found to be a better option in reducing menorrhagia compared with norethisterone in respect to a greater success rate, better compliance and cost effectiveness. Hence our study concludes ormeloxifene as a better choice over norethisterone in the treatment of AUB.
