UPDATES OF ‘AW3D30’ ALOS GLOBAL DIGITAL SURFACE MODEL IN ANTARCTICA WITH OTHER OPEN ACCESS DATASETS
Authors: Takaku J. , Tadono T. , Doutsu M. , Ohgushi F. , Kai H.
Published: July 2021

Abstract. In 2016, the first processing of the semi-global digital surface models (DSMs) utilizing all the archives of stereo imageries derived from the Panchromatic Remote sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS) was successfully completed. The dataset was freely released to the public in 30 m grid spacing as the ‘ALOS World 3D - 30m (AW3D30)’, which was generated from its original version processed in 5 m or 2.5 m grid spacing. The dataset has been updated since then to improve the absolute/relative height accuracies with additional calibrations. However, the most significant update that should be applied for improving the data usability is the filling of void areas, which correspond to approx. 10% of semiglobal coverage, mostly due to cloud covers. In 2020, we completed the filling process by using other open-access digital elevation models (DEMs) such as Shuttle Radar Topography Mission (SRTM) DEM, Advanced Spaceborne Thermal Emission and Reflection Radiometer Global DEM (ASTER GDEM), ArcticDEM, etc., except for Antarctica. In this paper, we report on the filling process of the remaining voids in Antarctica by using other open-access DEMs such as Reference Elevation Model of Antarctica (REMA) DSM, TerraSAR-X add-on for Digital Elevation Measurement (TanDEM-X, TDX) 90m DEM, and ASTER GDEM to complete the void-free semi-global AW3D30 datasets.

Published: July 2021

Abstract. Breakthrough imaging technologies are a potential solution to the plant phenotyping bottleneck in marker-assisted breeding and genetic mapping. X-Ray CT (computed tomography) technology is able to acquire the digital twin of root system architecture (RSA), however, advances in computational methods to digitally model spatial disposition of root system networks are urgently required.We extracted the root skeleton of the digital twin based on 3D data from X-ray CT, which is optimized for high-throughput and robust results. Significant root architectural traits such as number, length, growth angle, elongation rate and branching map can be easily extracted from the skeleton. The curve-skeleton extraction is computed based on a constrained Laplacian smoothing algorithm. This skeletal structure drives the registration procedure in temporal series. The experiment was carried out at the Ag Alumni Seed Phenotyping Facility (AAPF) at Purdue University in West Lafayette (IN, USA). Three samples of tomato root at 2 different times and three samples of corn root at 3 different times were scanned. The skeleton is able to accurately match the shape of the RSA based on a visual inspection.The results based on a visual inspection confirm the feasibility of the proposed methodology, providing scalability to a comprehensive analysis to high throughput root phenotyping.
HYBRID GIS-BIM APPROACH FOR THE TORINO DIGITAL-TWIN: THE IMPLEMENTATION OF A FLOOR-LEVEL 3D CITY GEODATABASE
Authors: Sammartano G. , Avena M. , Cappellazzo M. , Spanò A.
Published: July 2021

Abstract. The research tries to present a preliminary work into geo-spatial management of public administration assets thanks to interoperability of BIM-GIS models, related to urban scale scenarios. The strategy proposed tries to deepen the management, conversion and integration of databases related to public assets and particularly schools building, and related them into city-related geo-databases. The methodology, based on the real scenario of Torino Municipality and their needs addressed in recent studies in collaboration with FULL – Future Urban Legacy Lab from Politecnico di Torino, take advantage from the availability of two test dataset at different scale, with different potential and bottlenecks. The idea of developing a 3D digital twin of Torino actually stop long before the 3D city modelling only, but rather we have to deal with the integration and harmonization of existing databases. These data collections are often coming from different updating and based on non-homogeneous languages and data models. The data are often in table format and managed by different offices and as many management systems. Moreover, recently public administrations as the one of Torino, have increase availability of BIM models, especially for public assets, which need to be known, archived, and localized in a geographic dimension in order to benefit from the real strategic potential of a spatial-enabled facility management platform as Digital Twin. Combining the use of parametric modeler software (Revit) and visual programming language (Dynamo), the proposed methodology tries to elaborate rules on a set of shared language parameters (characterizing the buildings as attributes in both datasets: ID; address; construction; floors; rooms dimensions, use, floor; height; glass surfaces). This is tested as conversion workflow between the Municipality DB and the BIM model. This solution firstly allows the interaction and query between models, and then it proposes open issues once the enriched BIM model is imported into the geographical dimension of the Torino 3D city model Digital Twin (ArcGIS Pro platform), according to LOD standards, and enriched with semantic components from municipality DB.
ABWiSE v1.0: Toward and Agent-Based Approach to Simulating Wildfire Spread
Authors: Katan Jeffrey , Perez Liliana
Published: July 2021

Abstract. Wildfires are a complex phenomenon emerging from interactions between air, heat, and vegetation, and while they are an important component of many ecosystems’ dynamics, they pose great danger to those ecosystems, and human life and property. Wildfire simulation models are an important research tool that help further our understanding of fire behaviour and can allow experimentation without recourse to live fires. Current fire simulation models fit into two general categories: empirical models and physical models. We present a new modelling approach that uses agent-based modelling to combine the complexity found in physical models with the ease of computation of empirical models. Our model represents the fire front as a set of moving agents that respond to, and interact with, vegetation, wind, and terrain. We calibrate the model using two simulated fires and one real fire, and validate the model against another real fire and the interim behaviour of the real calibration fire. Our model successfully replicates these fires, with a Figure of Merit on par with simulations by the Prometheus simulation model. Our model is a stepping-stone in using agent-based modelling for fire behaviour simulation, as we demonstrate the ability of agent-based modelling to replicate fire behaviour through emergence alone.
Three in one: GPS-IR measurements of ground surface elevation changes, soil moisture, and snow depth at a permafrost site in the northeastern Qinghai–Tibet Plateau
Authors: Zhang Jiahua , Liu Lin , Su Lei , Che Tao
Published: July 2021

Abstract. Ground surface elevation changes, soil moisture, and snow
depth are all essential variables for studying the dynamics of the active
layer and permafrost. GPS interferometric reflectometry (GPS-IR) has been
used to measure surface elevation changes and snow depth in permafrost
areas. However, its applicability to estimating soil moisture in permafrost
regions has not been assessed. Moreover, these variables were usually
measured separately at different sites. Integrating their estimates at one
site facilitates the comprehensive utilization of GPS-IR in permafrost
studies. In this study, we run simulations to elucidate that the
commonly used GPS-IR algorithm for estimating soil moisture content cannot
be directly used in permafrost areas, because it does not consider the bias
introduced by the seasonal surface elevation changes due to active layer
thawing. We propose a solution to improve this default method by introducing
modeled surface elevation changes. We validate this modified method using
the GPS data and in situ observations at a permafrost site in the
northeastern Qinghai–Tibet Plateau (QTP). The root-mean-square error and
correlation coefficient between the GPS-IR estimates of soil moisture
content and the in situ ones improve from 1.85 % to 1.51 % and 0.71 to
0.82, respectively. We also propose a framework to integrate the GPS-IR
estimates of these three variables at one site and illustrate it using the
same site in the QTP as an example. This study highlights the improvement to
the default algorithm, which makes the GPS-IR valid in estimating soil
moisture content in permafrost areas. The three-in-one framework is able to
fully utilize the GPS-IR in permafrost areas and can be extended to other
sites such as those in the Arctic. This study is also the first to use
GPS-IR to estimate environmental variables in the QTP, which fills a spatial
gap and provides complementary measurements to ground temperature and active
layer thickness.

Published: July 2021

Mediante este trabajo se pretende analizar el impacto de la práctica coral en el contexto del Centro Penitenciario de Reinserción Social (CPRS) de “Santiaguito” en Almoloya de Juárez, en el Estado de México. Los destinatarios fueron las internas e internos del centro penitenciario mediante un taller de práctica vocal y coral, realizándose paralelamente la intervención y la investigación.
Las conclusiones de este trabajo muestran que los participantes desarrollaron y/o mejoraron habilidades específicas inherentes al hecho de cantar, así como habilidades socioemocionales.
 A través de un enfoque didáctico holístico los integrantes de ambos grupos desarrollaron la responsabilidad individual obteniendo progresivamente autoestima, confianza, seguridad y desinhibición. Así mismo, demostraron disposición para el trabajo cooperativo y para la interacción positiva entre iguales generando empatía y sentido de pertenencia. Las mujeres se empoderaron especialmente, tanto a nivel individual como grupal, venciendo la falta de habilidades vocales de partida y la situación de aislamiento e indefensión que mermaba sus habilidades socioemocionales en tanto que mujeres y reclusas en determinado contexto.
Las conclusiones de este trabajo ponen de manifiesto las potencialidades diversas de la práctica vocal en grupo como herramienta transformadora de primer orden, cuyo impacto se deja sentir en los individuos y en los grupos, mejorando la vida de las personas desde el punto de vista psicológico, emocional y social; favoreciendo el desarrollo integral del individuo que se expresa a través de la vivencia compartida del hecho artístico, generándose actitudes prosociales que, a medio plazo, fomentan la reinserción y la inclusión social, contribuyendo a dar respuesta a los desafíos de justicia social de las sociedades democráticas.
The Self-Portrait Experience (SPEX), una herramienta artística para la transformación individual y social
Authors: Nuñez Salmeron Cristina
Published: July 2021

La práctica artística de Cristina Núñez usando el autorretrato comenzó en 1988 cuando giró la cámara hacia sí misma para superar el auto-estigma derivado de la adicción. Un proceso que evolucionó de una práctica artística autodidacta a facilitar el autorretrato de otras personas, la llevó a idear The Self-Portrait Experience (SPEX). Desde 2004 Núñez realiza talleres SPEX en todo el mundo en diversos contextos, como el penitenciario, la salud mental, la recuperación de adicciones y la transición de los adolescentes. En estos talleres los participantes realizan un proceso "catalítico" transformando el dolor emocional en lo que se denomina obras de arte. La revisión de las múltiples percepciones de las imágenes producidas permite a los participantes ampliar la percepción de sí mismos. SPEX utiliza el poder de la fotografía digital ubicua de una manera que subvierte el formato común de 'selfie', aprovechando la expresión inconsciente para explorar las emociones, con el fin de obtener nuevas percepciones y estimular el proceso creativo como reflexivo. A través de la publicación de autorretratos y proyectos autobiográficos, se conectan las dimensiones personales y sociopolíticas. La práctica de Núñez con ella misma y con los demás propone un diálogo entre la expresión emocional y sus efectos de espejo en el público. El objetivo general es proporcionar beneficios sociales tangibles, en forma de identificación del espectador con los sujetos de las imágenes, más que de disociación y alienación.
Weaponized testimonial injustice
Authors: Almagro Manuel , Osorio Javier , Villanueva Neftalí
Published: July 2021

Theoretical tools aimed at making explicit the injustices suffered by certain socially disadvantaged groups might end up serving purposes which were not foreseen when the tools were first introduced. Nothing is inherently wrong with a shift in the scope of a theoretical tool: the popularization of a concept opens up the possibility of its use for several strategic purposes. The thesis that we defend in this paper is that some public figures cultivate a public persona for whom the conditions of the notion of testimonial injustice might be taken to apply, and this situation is exploited to their advantage, as a means to advance their political agendas. More specifically, they take advantage of this to generate situations of crossed disagreements, which in turn foster polarization.
Del Periodo de Adaptación al Tiempo de Acogida. Una Reflexión Colaborativa en Educación Infantil
Authors: Vizcarra Morales María Teresa , López-de-Arana Prado Elena , Gamito Gomez Rakel
Published: July 2021

Esta investigación analiza el proceso de reflexión colaborativa llevada a cabo por las educadoras de la Red Municipal de Escuelas Infantiles de Vitoria-Gasteiz para definir en su Proyecto Educativo los aspectos claves del periodo de adaptación, y su manera de entenderlo. Se ha realizado una investigación-acción desplegada en cuatro fases. En esta ocasión se presenta la tercera fase, en la que se reflexiona sobre lo que se hace actualmente durante el periodo de adaptación y cómo se deben transformar el lenguaje y los modos de acción en el futuro. En el estudio, toman parte 115 personas docentes de educación infantil, 12 investigadoras y 6 técnicas participando, en 8 grupos de trabajo para reconstruir el conocimiento gracias a diferentes estrategias. Las conclusiones evidencian que el tiempo de acogida, a diferencia del periodo de adaptación, supone aceptar a cada niña y a cada niño con lo que afectivamente traen a la escuela, para que se creen nuevos vínculos afectivos que les den seguridad, en lugar de obligarles a adaptarse a una estructura rígida prefijada con anterioridad.
Countering misinformation and disinformation during contentious episodes in a divided society: Tweeting the 2014 and 2015 Ardoyne parade disputes
Authors: Reilly Paul
Published: July 2021

Whereas there has been much research into the manufacture of ‘fake news’ to sow disunity within liberal democracies, little is known about how information disorders affect deeply divided societies. This paper addresses that gap in the literature by exploring how digital media are used to share misinformation and disinformation during contentious public demonstrations in Northern Ireland. It does so by reviewing the literature on social media information flows during acute crisis events, and qualitatively exploring the role of Twitter in spreading misinformation and disinformation during the 2014 and 2015 Ardoyne parade disputes. Results indicate that visual disinformation, presumably shared to inflame sectarian tensions during the parade, was quickly debunked in information flows co-curated by citizens and professional journalists. Online misinformation and disinformation appeared to have minimal impact on events on the ground, although there was some evidence of belief echoes among tweeters who distrusted the information provided by mainstream media.
Understanding cancel culture: Normative and unequal sanctioning
Authors: Saint-Louis Hervé
Published: July 2021

Cancel culture is a phenomenon where individuals transgressing norms are called out and ostracised on social media and other venues by members of the public. While its effects are decried by some and its existence denied by others, the processes that shape cancel culture are misunderstood. In this article, I argue that cancellation can only occur if participating third parties with oversight over transgressing individuals perform sanctions. Furthermore, I explore how cancel culture affects people unequally by looking at the phenomenon known as the Karens. Using social normative theories, I evaluate how women affected by cancellation are facing misogyny through cancel culture.
"Can I pin this?" The legal position of Pinterest and its users: An analysis of Pinterest's data storage policies and users' trust in the service
Authors: Kasakowskij Thomas , Kasakowskij Regina , Fietkiewicz Kaja J.
Published: July 2021

It has been known for some time that in the digital environment enormous data streams are generated in which data is disclosed, forwarded, and stored. Once on the Internet, data is difficult to control. Often when creating and/or sharing content on the Internet, legal concerns about copyright and data protection might arise among the user as well as the platform provider. The same holds true for Pinterest, especially when considering that the main feature of the service is the possibility to re-pin (hence, collect and publicly share) content from external Web sites and from other users (i.e., someone else’s creation). It is unclear how Pinterest handles the data of its users and external Web sites and protects it from misuse.

It is also questionable whether the users familiarize themselves with terms of use, privacy policy, and the use of cookies by Pinterest as well as their legal awareness when using the service. This study contributes to resolve this uncertainty and to secure a more precise picture of how data is handled from the company’s point of view. For this purpose, an online survey with 365 participants was carried out. It was found that many users do not read the terms and conditions or guidelines but trust the service. In addition, an investigation on Pinterest’s guidelines has shown that a great deal of different data is stored and indirectly passed on to other companies. It was also found that users in the European economic area are not protected against copyright infringements when using Pinterest. This could lead to problems with state authority, at least for European users.
The Role of Zakat in Overcoming Inflation and Unemployment: Revisiting the Trade-Off Theory
Authors: Antonio Mohammad Syafii , Ali Mohammad Mahbubi , Jebel Firdaus
Published: July 2021

The present study aims to examine the role of zakat in addressing unemployment and inflation, while also revisiting A.W. Phillips’ trade-off theory. The study adopts a qualitative methodology, using library research to critically analyse how zakat could address unemployment and inflation. The study argues that the optimal application of zakat could overcome the issue of unemployment while maintaining price stability. This is true since zakat can be distributed in two forms: consumptive and productive. Therefore, an increase in aggregate demand will always be followed by a rise in aggregate supply; the distribution of zakat in the consumptive form will increase aggregate demand, while the distribution of zakat for a productive purpose will increase aggregate supply. An increase in aggregate demand would in turn increase production, thus absorbing more labour as a result. This is where zakat addresses unemployment. On the other hand, a rise in aggregate demand will initially inflate the aggregate price. However, since the increase in aggregate demand is simultaneously followed by an increase in aggregate supply due to the distribution of zakat in its productive form, the price remains stable. Aggregate demand and aggregate supply cross at an equilibrium point. More importantly, the price is stable while the quantity of production is at its highest level. The findings of the study serve as a reference point for regulators formulating fiscal policy embedded in the zakat system.

В статті розглянуто проблеми становлення інформаційного середовища української держави у зв’язку з розвитком інформаційно-комунікаційних технологій, реклами сучасного способу життя в масових комунікаціях, комп’ютеризації освіти, поширення електронних пристроїв, що забезпечують комфорт і зручність у повсякденному житті.В науковій статті визначено, що значно зростає рівень інформаційнокогнітивна недостатності для прийняття рішень щодо захисту від знову виникаючих небезпек (загроз) і, насамперед, інформаційних. Цілком очевидно, що в таких умовах домінанта інформаційної безпеки колосально зростає. Тому чим вище рівень інтелектуалізації й інформатизації соціуму, тим значиміше й дієвіше має бути його інформаційна безпека.
Інформаційну сферу соціуму сьогодні цілком правомірно вважають домінуючою, а її зрілу форму розглядають як матеріально-технічну основу інформаційного суспільства і, разом з тим, складову частину ноосфери

Envejecimiento y control postural
Authors: Sánchez Videa Alexandro Marcelo , Martínez Carrasco Cecilia Alejandra
Published: July 2021

Varios investigadores creen que los factores que coadyuvan al envejecimiento pueden ser primarios (genética) o también secundarios (ejercicio, nutrición, lesiones y trastornos patológicos. Es por ese motivo que los adultos mayores manifiestan alteraciones del control reactivo, junto a retrasos de las diferentes respuestas musculares por lo que requieren aún más tiempo para restablecer su equilibrio. Además, existe un retraso en la activación de las respuestas posturales en el control del equilibrio proactivo, lo que produce una inestabilidad mayor para poder realizar las actividades de la vida cotidiana (levantarse, subir y bajar gradas, etc.). Varios sistemas que se incluyen dentro del equilibrio, control postural y motor se ven afectados al pasar los años, al igual que la misma hipotrofia muscular que comienza a partir de los 30 años si es que el individuo es sedentario; así como las fibras musculares de tipo I (oxidativa lenta, utilizada en actividades como control postural), que según varios estudios demostraron existe una pérdida de este tipo de fibras musculares relacionadas con la edad; de manera específica, describiendo a los factores que puedan contribuir al envejecimiento y sus complicaciones en la rehabilitación en adultos mayores tomando en cuenta los cambios relacionados con la vejez y la alteración del control postural.

Determinants of customer satisfaction in online grocery shopping
Authors: Ali Imran , Naushad Mohammad
Published: July 2021

This study aims to investigate the factors that influence consumer satisfaction with e-grocery shopping. Moreover, it also delves into factors that motivate shoppers to buy groceries from online retailers rather than conventional stores. A primary survey was administered to collect data. Initially, 500 questionnaires were circulated to respondents. People who have ordered groceries from online sites were the expected respondents. In this study, convenience sampling was used, and data were analyzed using structural equation modeling (SEM). The findings affirmed the relationship between consumer satisfaction and perceived convenience, risk factors, perceived product quality, and time value. However, perceived value and value for the time have a little significant effect on consumer satisfaction. There have been relatively few academic studies that look at the variables that influence customer satisfaction when shopping for groceries online. Most of the studies look at the variables that influence consumer satisfaction in the life insurance and financial services industries. By analyzing the data from Delhi and the Nation Capital Region (NCR) of Delhi, this research aims to bridge this gap available in the literature.

Published: July 2021

This study aims to explore the impact of satisfaction and trust on stickiness to Facebook. Also, it proposed that hedonic value, emotional value, and social value act as critical antecedents to Facebook stickiness. A quantitative methodology is used to examine the research questions. The research model was tested with data from 511 university students and five academic professors using an online survey. The proposed hypotheses were tested using regression analysis. Furthermore, Data were collected from targeted participants with Facebook experience, among the 511 participants, 353 were females (69.1%), and 158 were males (30.9%). The SEM analysis showed that satisfaction positively and significantly did affect stickiness, where trust did not. Also, results showed while hedonic value affected satisfaction, it did not impact trust. Hence, the results confirmed that hedonic value served as important value concerns for Facebook users. Nevertheless, the study found that both emotional value and social value impacted satisfaction and trust. The current research has enriched the existing study in the fields of customers’ satisfaction and trust on stickiness to Facebook. Moreover, this research is one of the earliest studies that proved that customer value creation serves as an important driving factor for customer satisfaction to generate stickiness to SNS. This study’s results help policymakers and designers of SNS to understand what value factors affect users’ stickiness to Facebook. Their marketing plans and decisions can be accordingly adjusted. This study suggests that marketers need to pay full attention to social value by adding more interactive features such as comments, likes, and shares in order to build social image and increase one’s social influence.

Developing an educational framework for using mobile learning during the era of COVID-19
Authors: Alhumaid Khadija
Published: July 2021

This paper focuses on the impact of fear emotion upon technology adoption by educators and students during Covid-19 pandemic. Mobile learning (m-learning) has been applied as the educational social platform within higher education institutes, public as well as private. The research hypotheses were associated with the Covid-19 influence on m-learning adoption with the rise of the coronavirus increasing types of fear. Such fears include fear caused by the education failure, family lockdown, and loss of social relationships. Teachers and students are mostly fearful of these aspects of the situation. An integrated model was established within the research, using theoretical models; the Planned Behavior theory, the Technology Acceptance Model, and the Expectation-Confirmation Model. The proposed integrated model (using PLS-SEM software) was analyzed using an online survey data, with 420 respondents from Zayed University, UAE. The findings indicated that attitude was the best predictor for using the m-learning system, followed by continuous intention, expectation confirmation, perceived usefulness, ease-of-use, perceived fear, behavioral control, and satisfaction. According to the research, during the coronavirus pandemic, if the m-learning system is adopted for educational reasons, the learning and teaching outcome proves quite promising. Yet there is a fear of the family being stressed, or of loss of friends, and also a fear of the results of future schooling. It is therefore necessary to assess the students efficiently during this pandemic so that the situation can be managed emotionally.

Published: July 2021

YouTube and TikTok have gained increasing recognition as social network sites to support online knowledge acquisition, sharing, and application via social media platforms in the medical field. This study examines which aspect of TikTok and YouTube stimulates doctors, nurses, and any other YouTube and TikTok in the medical setting, to rely on them as sources of knowledge acquisition and sharing to keep their medical repertoire updated. A hybrid model is designed to investigate users’ acceptance of YouTube and TikTok as social media platforms. The model focuses on four main external factors: content richness, innovativeness, satisfaction, and enjoyment. These factors are connected with two TAM constructs which are perceived ease of use and perceived usefulness. The results have shown that both YouTube and TikTok are affected by PEOU, PU, personal innovativeness, flow theory, and content richness. Both social media networks provide up-to-date sources described as useful, enjoyable, and relevant. Nevertheless, the comparative results have shown that YouTube has deeply influenced users’ medical perception and knowledge compared to TikTok. It is created for the very mere purpose of socialization and self-expression. In contrast, YouTube is used for educational and non-educational purposes due to the type of uploaded content and time management. Therefore, TikTok developers and influencers should initiate highly specialized videos and create content that raises awareness of medical field issues.

Amrtadi Churna is an Ayurvedic polyherbal formulation containing three herbs viz., Amalaki (Emblica officinalis), Gokshur (Tribulus terrestris) and Guduchi (Tinospora cordifolia). It is prescribed in India for immunomodulation and treating hyperacidity. The present work reports the acute and sub-acute toxicity assessment of Amrtadi Churna on experimental animals to rule whether it might produce toxicity on herb-herb interactions by combining its ingredient. The results showed that, the single administration of high dose (5000 mg/kg) of the Churna neither induced mortality nor any adverse toxicity signs in rats, suggesting its practically non-toxic nature in the therapeutic doses. Sub-acute toxicity testing results of hematology, serum biochemistry and organ histology showed that the product did not induce any toxic signs at the tested dose levels. However, it produced an apparently harmless hyperbilirubinemia without any signs of liver damage. There were no major gender specific variations except a few hematological parameters. It was concluded that, Amrtadi Churna could be relatively safe at therapeutic dose levels, ruling out any serious side effects by the interaction of its three herbal ingredients.

A simple, sensitive and rapid high performance liquid chromatographic method has been developed for the determination of Propofol. The main focus of the method was to determine Propofol in solution form as well as in marketed formulation. Chromatographic separation was achieved on Inertsil ODS-3V column (250mm x 4.6mm; 5µm) with a mobile phase consisting of methanol: water (85:15), with a flow rate of 1.0ml/min (UV detection at 270nm). Linearity was observed over the concentration range of 10-110µg/ml with a regression equation y=88048x + 44524 and having a regression value (R2) of 0.999. The LOD and LOQ values found to be 10ng and 100ng, respectively. No changes found in ruggedness and robustness studies. The percentage of recovery was found to be 95.25% to 101.81%. Validation studies revealed that the method was specific, accurate, precise, reliable, robust, reproducible and suitable for the quantitative analysis in its pharmaceutical formulations.

Body mass index (BMI) is a significant marker in assessing the health risk factors of an individual. Although, the discovery of BMI is over 200 years, however, its application as a measure of health is fairly new. Hitherto, the prevalence of higher BMI amongst university students is on the rise. Consequently, the present study endeavor to investigate the association of BMI and other health-related parameters namely; per cent body fat, visceral fat, basal metabolic rate (BMR), systolic and diastolic blood pressure, resting heart rate, core and upper muscle endurance, maximum oxygen consumption (V02max) and metabolic equivalent (MET). A total number of 232 university students were enrolled and completed the physical fitness assessments and health indicator measurement of the variables. A multiple Linear Regression (MLR) was used to observe the association of the BMI as the dependent variable with the physical fitness as well as health parameters as independent variables. A significant regression model was obtained F (3.225, 5) = 301.104, P <0.0001, R2 = 0.869 demonstrating that the model has accounted for about 87% variability of the whole dataset. Sensitivity analysis demonstrated that per cent body fat, visceral fat, BMR, as well as VO2max, are the major contributors towards the model prediction P <0.001. Moreover, positive significant relationships were detected between the BMI, per cent body fat, visceral fat, BMR, systolic and diastolic blood pressure whilst negative association between the BMI and performance in upper muscle endurance and VO2max were noted. BMI index could be a potential marker of assessing university students’ health-related risks that would consequently reveal vital information about their overall health status.

Capsicum annum L. is a potential natural plant that have a lot of various pharmacological effects, including as anticancer agent. This study Aim to analyze Capsicum annum extract (CAE) on T47D cells. CAE (10, 20, 40, 60, 80µg/mL) treated on T47D cells to determined IC50 value by MTT assay. Apoptosis induction is also investigated through caspase-3 expressions (IC50, 2IC50). The present study showed that CAE suppress T47D cells proliferation with IC50 value of 75.81µg/mL. The caspase-3 expression on 2IC50 is higher (67.16%) than IC50 (52.16%). This result indicate that CAE has ability as anticancer agent by inhibiting cell growth and induce apoptosis through caspase-3 expression on T47D cells. Further study of CAE holds potential for novel therapies of cancer prevention and treatment.
El Transhumanismo Ilustrado
Authors: Gayozzo Piero
Published: July 2021

El siguiente artículo propone la idea de que el transhumanismo no solo es un movimiento inspirado en la ilustración, sino que en su seno puede identificarse una corriente que actualiza los valores ilustrados para la Cuarta Revolución Industrial. Para sostener la hipótesis se revisó la literatura disponible sobre transhumanismo y se tomó como referencia la obra de algunos autores de la Ilustración francesa, entre ellos D’Holbach, Voltaire, Diderot, Condorcet y Helvétius. Se concluyó que los valores actualizados que propone el transhumanismo ilustrado son los siguientes: progreso en forma de evolución dirigida, libertad como libertad morfológica, igualdad como igualdad de consciencia, moral y tecnológica y finalmente el secularismo como la constante búsqueda por superar las supersticiones.
Medial soft-tissue complex of the knee: Current concepts, controversies, and future directions of the forgotten unit
Authors: Requicha Francisco , Comley Andrew
Published: July 2021

The medial side of the knee is comprised of ligaments, myotendinous and meniscal structures that work as a unit to stabilize the joint. The superficial medial collateral ligament is its core structure. Still, all elements of the medial side have load-sharing relationships, leading to a cascade of events in the scenario of insufficiency of any of them. Understanding the medial soft tissue structures as part of a unit is of utmost importance because the most common ligaments damaged in knee injuries belong to it. Surprisingly, there is a lack of high-level evidence published around the issue, and most studies focus on the superficial medial collateral ligament, overlooking the complexity of these injuries. Acknowledging the consequences for joint biomechanics and treatment outcomes, interest in this area is growing between researchers. Emerging evidence may become a game-changer in the future management of these injuries.

Based on a thorough research of published literature, this review provides a current biomechanical concepts and clinical guidance to treat these injuries.

Purpose of review

This is a comprehensive review of the literature regarding the use of ketamine as a treatment for treatment-resistant depression (TRD). It covers the epidemiology, risk factors, pathophysiology, and current treatment modalities regarding Major Depressive Disorder (MDD) and TRD. It provides background on the mechanism of action of ketamine, its history, current approved and off-label indications in the field of psychiatry, and then provides an overview of the existing evidence for the use of ketamine in the treatment of TRD.

Recent findings

MDD is a mental illness that puts an enormous strain on the affected and a high socio-economic burden on society. The illness is complex and combines genetic, pathophysiologic, and environmental factors that combine to negatively affect neurotransmitter balance in the brain. Additional evidence suggests dysregulation of the hypothalamic-pituitary (HPA) axis, brain-derived neurotrophic factor (BDNF), vitamin D levels, and involvement of pro-inflammatory markers. Core symptoms include depressed mood or anhedonia, combined with neurovegetative symptoms such as sleep impairment, changes in appetite, feelings of worthlessness and guilt, and psychomotor retardation. Current first-line treatment options are antidepressants of the selective serotonin reuptake inhibitor (SSRI) and serotonin-norepinephrine reuptake inhibitor (SNRI) class. Failure to respond to two adequate trials of treatment meets the criteria for TRD. Esketamine (Spravato) is an NMDA-receptor antagonist with additional AMPA-receptor agonist properties, which the FDA approved in 2019 to treat adult TRD in conjunction with an oral antidepressant. It can be administered intranasally, providing a rapid response and proven effective and safe. Additional research suggests that oral ketamine might be effective for PTSD and anxiety disorders. Intravenous administration of ketamine has also shown benefits for acute suicidal ideation and depression and substance use to reduce relapse rates.

TRD is associated with huge costs on individual and societal levels. Underlying disease processes are multifactorial and not well understood. Adjunctive therapies for TRD with proven benefits exist, but acutely depressed and suicidal patients often require prolonged inpatient stabilization. Intranasal esketamine is a new FDA-approved alternative with rapid benefit for TRD, which has also shown a rapid reduction in suicidal ideation while maintaining a favorable side-effect profile. Additional potential off-label uses for ketamine in psychiatric disorders have been studied, including PTSD, anxiety disorders, bipolar depression, and substance use disorders.
