Visibilización de la agroecología periurbana durante la pandemia: el uso de las redes sociales para la militancia del plato
Authors: POGGI MARINA , Pinto Lucas Henrique 
Published: December 2020

Nos proponemos indagar los modos en los que -a partir de la pandemia mundial por COVID-19- los productos agroecológicos se visibilizaron virtualmente y el debate acerca de la soberanía alimentaria seincrementó en las preocupaciones sociales colectivas. En este sentido, partimos de que las redes sociales virtuales son potenciadas por las tecnologías de la información y la comunicación, vinculadas a la mirada tradicional de red conformada por entidades y por relaciones entre esas entidades. A partir del advenimiento del mundo global, las redes fueron revitalizadas por la web y adquirieron nuevas dinámicas sociales, tomaron diferentes formas y dimensiones, ya que en el espacio virtual se multiplican (Kauchakje, Penna, Frey, Klaus y Duarte, 2006). Con el objetivo de indagar en los hábitos de consumo de alimentospre-pandemia y las modificaciones realizadas durante la misma, elaboramos una encuesta cuyos resultados presentamos en este trabajo, pretendiendo con ello aportar datos actuales de las elecciones, posibilidades de acceso, conocimiento, etc., acerca de los alimentos y su procedencia. Apelamos a los conceptos de agroecología y periurbano, considerando las prácticas y el espacio de estudio. El primero refiere al“campo de conocimientos que reúne, sintetiza y aplica conocimientos de la agronomía, la ecología, la sociología, la etnobotánica y otras ciencias afines, con una óptica holística y sistémica, para generar, validar yaplicar estrategias adecuadas para el diseño, el manejo y la evaluación de sistemas agroalimentarios sustentables” (Sarandón y Flores, 2020, p. 59). El segundo se define como “territorio de borde sometido a procesos sociales y económicos relacionados con la valorización capitalista del espacio, como consecuencia de la incorporación real o potencial de nuevas tierras a la ciudad” (Feito y Barsky, 2020, p. 897). Si biencontemplaremos diversas experiencias, nos centraremos en el caso de la cooperativa de consumo “Pueblo a Pueblo”, una iniciativa de comercialización que propone constituirse como alternativa de circuito cortode alimentos sanos en las ciudades, mediante trabajo digno.

A cidade-lar e o lar-cidade
Authors: Braga Robson da Silva 
Published: December 2020

Em 2020, durante o isolamento social de combate à Covid-19, o ambiente doméstico despontou como uma extensão da cidade por meio das materialidades das tecnologias de comunicação e informação, numa intensificação da confusão entre público e privado que vem sendo consolidada na contemporaneidade. As reuniões remotas amplificaram um processo de exposição da intimidade que já vem se consolidando com as redes sociais desde o início dos anos 2000. Com base nisso, este artigo analisa de que modo grupos de pessoas têm utilizado ferramentas de videoconferência em substituição aos encontros realizados antes da quarentena na cidade de Fortaleza, capital que, em março de 2020, chegou a ser a mais afetada do Brasil, segundo dados do Ministério da Saúde. Como recorte, analisamos o uso de três ambientes virtuais (1. lives de apresentações de artistas; 2. reuniões remotas de trabalho; 3. e comemorações virtuais de aniversário) com base em dois procedimentos principais: a) observação participante feita pelo pesquisador; b) e entrevista semiaberta com cinco moradores de Fortaleza. Os eventos analisados foram realizados por meio de plataformas como YouTube e Instagram (no caso das lives de artistas) e por meio de plataformas de reuniões virtuais, a exemplo de Jitsi, Zoom e Skype.

La memoria en tiempos de pandemia. Registro visual del 24 de marzo de 2020 en Argentina.
Authors: Rodríguez María Graciela , Gamarnik Cora , Vázquez Cecilia 
Published: December 2020

Este Ensayo Visual propone una reflexión sobre los vínculos entre memoria, imágenes y ciudad, a partir de una selección de imágenes que acompañaron el evento del 24 de marzo de 2020, cuatro días después de que comenzara a regir en Argentina el Aislamiento Social Preventivo y Obligatorio (ASPO). Los organismos de Derechos Humanos tomaron la iniciativa de realizar una campaña para conmemorar a través de otros recursos este aniversario del 24 de marzo teniendo en cuenta las restricciones de circulación. Las ciudades se llenaron ese día de carteles caseros y pequeñas obras artísticas que fueron a su vez retratados por fotógrafos profesionales o amateurs. Entendemos que el formato de Ensayo Visual nos permite combinar un repertorio de imágenes que condensan modos alternativos de ejercitar la memoria, con algunas reflexiones –urgentes, excepcionales, provisorias- que nos despierta la pandemia.

Novel Phytochemical Constituents and their Potential to Manage Diabetes
Authors: Khalivulla Shaik I. , Mohammed Arifullah , Mallikarjuna Kokkanti 
Published: December 2020

Background:
Diabetes is a chronic disease affecting a large population worldwide and stands as one
of the major global health challenges to be tackled. According to World Health Organization, about 400 million
are having diabetes worldwide and it is the seventh leading cause of deaths in 2016. Plant-based natural products
have been in use from ancient times as ethnomedicine for the treatment of several diseases, including diabetes.
As a result of that, there are several reports on plant-based natural products displaying antidiabetic activity.
In the current review, such antidiabetic potential compounds reported from all plant sources along with their
chemical structures are collected, presented and discussed. These kinds of reports are essential to pool the
available information to one source, followed by statistical analysis and screening to check the efficacy of all
known compounds in a comparative sense. This kind of analysis can give rise to a few potential compounds
from hundreds, which can further be screened through in vitro and in vivo studies, and human trails leading to
the drug development.

Methods:
Phytochemicals, along with their potential antidiabetic property, were classified according to their
basic chemical skeleton. The chemical structures of all the compounds with antidiabetic activities were elucidated
in the present review. In addition to this, the distribution and their other remarkable pharmacological activities
of each species are also included.

Results:
The scrutiny of literature led to the identification of 44 plants with antidiabetic compounds (70) and
other pharmacological activities. For the sake of information, the distribution of each species in the world is
given. Many plant derivatives may exert anti-diabetic properties by improving or mimicking insulin production
or action. Different classes of compounds including sulfur compounds (1-4), alkaloids (5-11), phenolic compounds
(12-17), tannins (18-23), phenylpropanoids (24-27), xanthanoids (28-31), amino acid (32), stilbenoid
(33), benzofuran (34), coumarin (35), flavonoids (36-49) and terpenoids (50-70) were found to be potential active
compounds for antidiabetic activity. Of the 70 listed compounds, majorly 17 compounds are obtained from
triterpenoids, 13 from flavonoids and 7 from alkaloids. Among all the 44 plant species, the maximum number
(7) of compounds were isolated from Lagerstroemia speciosa followed by Momordica charantia (6) and S. oblonga
with 5 compounds.

Conclusion:
This is the first paper to summarize the established chemical structures of phytochemicals that
have been successfully screened for antidiabetic potential and their mechanisms of inhibition. The reported
compounds could be considered as potential lead molecules for the treatment of type-2 diabetes. Further, molecular
and clinical trials are required to select and establish therapeutic drug candidates.
Anti-carcinogenic Effect of Cathepsin K Inhibitor, Odanacatib with a Low Dose of Cisplatin Against Human Breast Carcinoma MCF-7 and MDA-MB231 Cells
Authors: Vashum Yaongamphi , Kottaiswamy Amuthavalli , Loganathan Tholcopiyan , Sheriff Fathima B. , Samuel Shila 
Published: December 2020

Background:
A cross-linking agent commonly used for cancer chemotherapy is a platinum
compound such as cisplatin. However, with the acquisition of cellular drug resistance and adverse
side effects, the potency of cisplatin is, therefore, often tempered. To overcome these issues,
the present study has established the use of cathepsin k (CTSK) inhibitor as a potent chemosensitizer.

Methods:
The cytotoxic effect of cisplatin and odanacatib (ODN) on two different breast cancer patient-
derived cell lines, MDA-MB-231 and MCF-7, was assessed by MTT-based colorimetric assay.
The drug interaction coefficient CDI was used to evaluate the synergistically inhibitory impact
of the drug combination and immunoblot was used to examine the expression of certain proteins responsible
for cell survival and the mechanism of apoptosis.

Results:
In this study, we found that IC50 of ODN in combination with cisplatin (half of IC25) induced
a synergistic cytotoxic effect in different breast cancer cells. Diminished expression of Bcl-2
and increased expression of Bax aroused the cytochrome release, that triggered caspase-9 and -3 activation
in the combinatorial group. ODN with a lower dose of cisplatin significantly inhibited the
protein expression of novel chemoresistant factors such as STAT3, NFκB and IL-6.

Conclusion:
This study highlights the potential effects of the combination of ODN with a reduced
dose of cisplatin on improving the growth inhibition and apoptosis-inducing effect on breast cancer
cells via combined inhibition of NF-κB-induced IL-6 and STAT3 activation. The study result
suggests that the further development of this novel inhibitor in combination with a low dose of standard
cisplatin-based chemotherapy may contribute to an alternative treatment option for certain
cancers.
Cell Arrest and Apoptosis Induced by the Next Generation of Vanadium Based Drugs: Action Mechanism to Structure Relation and Future Perspectives
Authors: Vlasiou Manos C. , Pafiti Kyriaki S. 
Published: December 2020

Background:
Every year, we encounter more projects indicating the promising anticancer activity of
vanadium molecules against different types of cancer cells. The new generation of metal-based drugs, targets
the energy supplies of the cell through ROS generation leading them to cell arrest and apoptosis. The relatively
low toxicity of vanadium metal, the different oxidation states that it can occur and in general, the lipophilicity
of transition metals, gave attention to vanadium after the exhausting research in platinum-based drugs.
Herein, the latest advances in the apoptotic activity of vanadium complex molecules have been reviewed and revealed
the structure to action relationship. Future perspectives of vanadium anticancer drugs are also discussed.

Methods:
Data were collected from Web of Science, Scopus, Pubmed, through searching of these keywords:
“apoptosis”, “anticancer drugs”, “vanadium complexes”, “synthesis” and “cell arrest”.

Results:
A good amount of vanadium complexes gave promising results over the past few years, showing that a
more careful approach of a ligand design could give rise to the next generation of vanadium drugs.

Conclusion:
The low toxicity of vanadium ion in combination with its V(IV) species selectivity gives the vanadium
a head starts against other transition metal complexes.

Authors: Ge Yanyan , Wu Juanjuan , Xiao Maohua , Su Zichao 
Published: December 2020

Background:
Crop straw is a valuable renewable biological resource. In this study, a mobile straw granulator
was designed to fully and efficiently use crop straw. The key crushing mechanism device of the mobile straw granulator
was also designed in detail.

Methods:
The first three natural frequencies and vibration modes of the crushing roller are obtained by applying ANSYSWorkbench software to the modal analysis of the crushing roller.

Results:
The lowest natural frequency of the crushing roller was 165.83 Hz, which was higher than its working frequency
of 30 Hz and would not cause resonance. Three factors and three levels were tested using the average resistance of the
blade as an index and the blade edge angle, the blade thickness, and the blade end width as the test factors.

Conclusion:
The optimal parameter combination obtained by software analysis is blade edge angle of 30°, blade thickness
of 8 mm, and blade width of 75 mm. With this parameter combination, the blade power consumption is the smallest, the
service life is the largest, and the crushing effect is the best.
A Robust Fuzzy Decision Making on Global Warming
Authors: Bhattacharya Kousik , Kumar De Sujit , Nayak Prasun Kumar 
Published: December 2020

Background:
In this article we develop a global warming indicator model under fuzzy system. It is the light of
sun that environmental pollution is responsible for the cause and immediate effect of global warming. Limited amount of
oxygen in the air, continuous decrease of fresh water volume, more especially the amount of drinking water and the rise of
temperature in the globe are the major symptoms (variants) of global warming. Thus, to capture the facts we need to
develop a mathematical model which has not yet been developed by the earlier researchers.

Introduction:
An efficient literature survey has been done over the three major parameters of the environment namely
oxygen, fresh water and surface temperature exclusively. In fact we have accumulated 150 years-data structure for these
major components and have analyzed them under fuzzy system so as to develop an efficient global warming indicator
model.

Method:
First of all, we gave few definitions on fuzzy set. Utilizing the data set we have constructed appropriate
membership functions of the three major components of the environment. Then applying goal programming problem, we
have constructed a fuzzy global warming indicator (GWI) model subject to some goal constraints with respective priority
vectors (Scenario 1 and Scenario 2). An extension has also been included for multi-valued goal programming problem and
numerical illustrations have been done with the help of LINGO software.

Result:
Numerical study reveals that the GWI takes maximum and minimum values in a decreasing manner as time
increases. It is seen that for scenario 1, the global environmental system will attain its stability after 30 years by degrading
31% of GWI with respect to present base line. For scenario 2, after the same time the global environmental system will
attain its stability quite slowly by degrading 28% of GWI with respect to present base line.

Conclusion:
Here we have studied a mathematical model of global warming first time using fuzzy system. No other
mathematical models have been existed in the literature. Thus, the basic novelty lies in a robust decision-making approach
which shows the expected time of extinction of major species in this world. However, extensive study on data analytics
over major environmental components can tell the stability of the global warming indicator and hence the future fate of
the globe also.

Formulation of the problem. The completeness of the characteristics of one of the most serious threats to the security of information today – its leakage through the transient electromagnetic pulse emanation standard (TEMPEST) from computer equipment (CE) is determined not only by the number of detectable signs of leakage but also by several other parameters characterizing the dynamics of the implementation of such a threat. The established patterns in the scenarios of violators’ actions associated with the use of technical reconnaissance equipment (TRQ) to intercept informative TEMPEST signals from computer equipment made it possible to form a model of all possible options for using TRQ to obtain confidential information processed by computer equipment. The proposed model provides the implementation of the methodological principles of the recognition theory for a more complete characterization of threats of information leakage through the channels of spurious electromagnetic radiation and interference from CE in the process of their detection.Objective. Development of methodological grounds for presenting signs of the violator’s implementation of certain functions associated with the use of technical reconnaissance equipment to intercept informative signals of spurious electromagnetic radiation and interference from computer equipment as signs that identify the most significant conditions for the recognition and prevention of such threats.Results. Methodological solutions for the identification of three states significant for the prevention of threats are given based on the structuring of the functional representation of the intruder’s actions to implement such threats. Mathematical models for assessing the predicted amount of information disclosed in the process of intercepting TEMPEST informative signals from computer equipment, and assessing the level of security threats in case of interception of information are also presented.Practical significance. The paper presents the main options for the operation of a complex of programs for recognizing threats of information leakage through TEMPEST channels from computer equipment developed within the framework of the presented methodology.

Published: December 2020

Stress is a common mental issue among students during the COVID-19 outbreak. This study aimed to determine and to compare the stress level among health sciences and non-health sciences students during the Movement Control Order. Cross-sectional study design was used, and the Perceived Stress Scale questionnaire was distributed for this study. The majority of 145 students (81.4%) had a moderate stress level, and there was no significant difference in the mean of the stress level between the health sciences and non-health sciences students(p>0.05). This research provides preliminary insight into the stress level among students and the need for further actions.

Improving Heart Disease Risk Through Quality-Focused Diet Logging: Pre-Post Study of a Diet Quality Tracking App
Authors: Kwon Bum Chul , VanDam Courtland , Chiuve Stephanie E , Choi Hyung Wook , Entler Paul , Tan Pang-Ning , Huh-Yoo Jina 
Published: December 2020

Background
Diet-tracking mobile apps have gained increased interest from both academic and clinical fields. However, quantity-focused diet tracking (eg, calorie counting) can be time-consuming and tedious, leading to unsustained adoption. Diet quality—focusing on high-quality dietary patterns rather than quantifying diet into calories—has shown effectiveness in improving heart disease risk. The Healthy Heart Score (HHS) predicts 20-year cardiovascular risks based on the consumption of foods from quality-focused food categories, rather than detailed serving sizes. No studies have examined how mobile health (mHealth) apps focusing on diet quality can bring promising results in health outcomes and ease of adoption.

Objective
This study aims to design a mobile app to support the HHS-informed quality-focused dietary approach by enabling users to log simplified diet quality and view its real-time impact on future heart disease risks. Users were asked to log food categories that are the main predictors of the HHS. We measured the app’s feasibility and efficacy in improving individuals’ clinical and behavioral factors that affect future heart disease risks and app use.

Methods
We recruited 38 participants who were overweight or obese with high heart disease risk and who used the app for 5 weeks and measured weight, blood sugar, blood pressure, HHS, and diet score (DS)—the measurement for diet quality—at baseline and week 5 of the intervention.

Results
Most participants (30/38, 79%) used the app every week and showed significant improvements in DS (baseline: mean 1.31, SD 1.14; week 5: mean 2.36, SD 2.48; 2-tailed t test t29=−2.85; P=.008) and HHS (baseline: mean 22.94, SD 18.86; week 4: mean 22.15, SD 18.58; t29=2.41; P=.02) at week 5, although only 10 participants (10/38, 26%) checked their HHS risk scores more than once. Other outcomes, including weight, blood sugar, and blood pressure, did not show significant changes.

Conclusions
Our study showed that our logging tool significantly improved dietary choices. Participants were not interested in seeing the HHS and perceived logging diet categories irrelevant to improving the HHS as important. We discuss the complexities of addressing health risks and quantity- versus quality-based health monitoring and incorporating secondary behavior change goals that matter to users when designing mHealth apps.
