Objective:

The present study aims to evaluate the antioxidant effect of beta-glucan on oxidative DNA damage by comet assay.

Methods:

A total of 19 adult females and males diagnosed with stage 3-4 colorectal cancer and a control group of 20 age-matched healthy subjects were enrolled in the study. Blood samples of the participants were analyzed using Comet Assay for the parameters of DNA damage.

Results:

Significantly increased DNA damage was observed in patients versus the control group as indicated by greater values of tail moment, tail percent DNA and tail length. Following incubation with β-glucan, a substantial reduction was found in the aforementioned parameters of DNA damage. Comet assay revealed significant levels of endogenous DNA damage in patients as shown by remarkable increases in the tail moment, the percentage of DNA in the tail and the tail length values, in comparison with the control group. Following treatment of fresh whole blood with β-glucan incubation, DNA damages were significantly reduced, but lower values were observed after β-glucan incubation in the patient group versus control group.

Conclusion:

β-Glucan was found to reduce DNA damage substantially in colorectal cancer patients and show antimutagenic effects. Our results suggested that dietary β-glucan intake might be important in the genesis of colorectal cancer tumors.

O método Quadripolar e a sua aplicação em trabalhos científicos
Authors: Gouveia Luís Borges , Nogueira Daniele
Published: February 2021

This article presents a study on the use and exploitation of the quadripolar method in the context of master's and doctoral studies mainly in Information Science. To this end, studies conducted in Portugal and Brazil between 2006 and 2019 were surveyed. In the field of Information Science, whose object information is taken as a phenomenon, therefore with greater complexity and scope, namely social, a methodological approach that deals with this complexity is required. Thus, the quadripolar method is a viable option that assists in the approach of phenomena associated with information, its use and exploitation, in the context of Information Science. The Quadripolar Method proposes a multidisciplinary approach in which it combines both the qualitative and quantitative approaches, proposing a dynamic research instrument, based on the result of the interaction between four poles: epistemological; theoretical; technical and morphological. This approach allows the double study of the problem in question, both in its context and as a representative of a common class of similar problems.

A hybrid mid-infrared photodetector has been implemented, in which silicon carbide (SiC) particles are used to increase the interaction of the electromagnetic field with the electronic subsystem of quantum wells. On the basis of direct measurements of infrared photoconductivity and calculations within the framework of the finite difference method in the time domain, it is shown that this approach makes it possible to increase the sensitivity of such infrared photodetector to electromagnetic radiation by reversing the direction of polarization of the electric field, including in the near zone of SiC particles.

COVID-19 Vaccine Hesitancy in Canada: Content Analysis of Tweets Using the Theoretical Domains Framework
Authors: Griffith Janessa , Marani Husayn , Monkman Helen
Published: February 2021

Background

With the approval of two COVID-19 vaccines in Canada, many people feel a sense of relief, as hope is on the horizon. However, only about 75% of people in Canada plan to receive one of the vaccines.

Objective

The purpose of this study is to determine the reasons why people in Canada feel hesitant toward receiving a COVID-19 vaccine.

Methods

We screened 3915 tweets from public Twitter profiles in Canada by using the search words “vaccine” and “COVID.” The tweets that met the inclusion criteria (ie, those about COVID-19 vaccine hesitancy) were coded via content analysis. Codes were then organized into themes and interpreted by using the Theoretical Domains Framework.

Results

Overall, 605 tweets were identified as those about COVID-19 vaccine hesitancy. Vaccine hesitancy stemmed from the following themes: concerns over safety, suspicion about political or economic forces driving the COVID-19 pandemic or vaccine development, a lack of knowledge about the vaccine, antivaccine or confusing messages from authority figures, and a lack of legal liability from vaccine companies. This study also examined mistrust toward the medical industry not due to hesitancy, but due to the legacy of communities marginalized by health care institutions. These themes were categorized into the following five Theoretical Domains Framework constructs: knowledge, beliefs about consequences, environmental context and resources, social influence, and emotion.

Conclusions

With the World Health Organization stating that one of the worst threats to global health is vaccine hesitancy, it is important to have a comprehensive understanding of the reasons behind this reluctance. By using a behavioral science framework, this study adds to the emerging knowledge about vaccine hesitancy in relation to COVID-19 vaccines by analyzing public discourse in tweets in real time. Health care leaders and clinicians may use this knowledge to develop public health interventions that are responsive to the concerns of people who are hesitant to receive vaccines.
A Multidimensional Data Fusion Model Based on Deep Learning for a Patient Similarity Network (Preprint)
Authors: Serhani Mohamed Adel , T. El Kassabi Hadeel , T. El Kassabi Hadeel , Oulahaj Aberrahim , Khalil Khaled
Published: February 2021

BACKGROUND

Precision medicine is a novel approach for patient care. It allows the prescription of the appropriate drug as well as suitable treatments to the right patient at the right time. It can be envisioned as the comparison of a new patient with existing patients having similar characteristics, which can be referred to as patient similarity. Several statistical, data mining, and deep learning models have been used to build and apply patient similarity network (PSN) for various purposes. However, the challenges associated with data heterogeneity and dimensionality make it difficult to use a single model that addresses both the challenges of reducing data dimensionality and capturing features of diverse data types, including contextual and longitudinal data. Furthermore, when applying multiple models, we can observe the additional challenges associated with the development of an optimum aggregation scheme that maintains high accuracy and preserves data veracity.

OBJECTIVE

In this study, we propose a multi-model PSN that considers heterogeneous data with static and dynamic characteristics for disease diagnosis for improving prediction accuracy. The static data model manages the data obtained from patient profiles, whereas the dynamic data model manages longitudinal data from patient treatment pathways and clinical data.

METHODS

We propose a combination of deep learning models and patient similarity network to obtain abundant clinical evidence and extract relevant information based on which similar patients can be explored and compared, thereby obtaining more accurate and comprehensive diagnosis and recommendations. We use the bidirectional encoder representations from transformers (BERT) to process and analyze the contextual data and generate word embedding, where semantic features are captured using a CNN. Dynamic data is analyzed using a long–short-term memory (LSTM)-based autoencoder, which reduces data dimensionality while preserving the temporal features of the data. Furthermore, we propose an aggregation-based fusion approach in which temporal data and clinical narrative data are combined for estimating the patient similarity.

RESULTS

We evaluated our proposed method through a series of experiments. The obtained results proved that our proposed deep learning-based PSN fusion model provides higher classification accuracy in determining various patient health outcomes when compared with other traditional classification algorithms.

CONCLUSIONS

Our multi-model highlights the intensity of the similarity between pairs of patients, thereby realizing precise diagnosis and recommendations for a new patient.

Published: February 2021

Background and objective

The optimal ambulatory management of renin-angiotensin-aldosterone system inhibitor (RAASi)–related hyperkalemia to reduce the risk of recurrence is unknown. We examined the risk of hyperkalemia recurrence on the basis of outpatient pharmacologic changes following an episode of RAASi-related hyperkalemia.

Design

We performed a population-based, retrospective cohort study of older adults (n=49,571; mean age 79 years) who developed hyperkalemia (potassium ≥5.3 mEq/L) while on a RAASi and were grouped as follows: no intervention, RAASi discontinuation, RAASi dose decrease, new diuretic, diuretic dose increase, or sodium polystyrene sulfonate within 30 days. The primary outcome was hyperkalemia recurrence, with secondary outcomes of cardiovascular events and all-cause mortality within 1 year.

Results

Among patients who received a pharmacologic intervention (23% of the cohort), RAASi discontinuation was the most commonly prescribed strategy (74%), followed by RAASi decrease (15%), diuretic increase (7%), new diuretic (3%), and sodium polystyrene sulfonate (1%). A total of 16,977 (34%) recurrent hyperkalemia events occurred within 1 year. Compared with no intervention (35%, referent), the cumulative incidence of recurrent hyperkalemia was lower with RAASi discontinuation (29%; hazard ratio, 0.82; 95% confidence interval, 0.78 to 0.85), whereas there was no difference with RAASi dose decrease (36%; hazard ratio, 0.94; 95% confidence interval, 0.86 to 1.02), new diuretic (32%; hazard ratio, 0.95; 95% confidence interval, 0.78 to 1.17), or diuretic increase (38%; hazard ratio, 0.99; 95% confidence interval, 0.87 to 1.12) and a higher incidence with sodium polystyrene sulfonate (55%; hazard ratio, 1.30; 95% confidence interval, 1.04 to 1.63). RAASi discontinuation was not associated with a higher risk of 1-year cardiovascular events (hazard ratio, 0.96; 95% confidence interval, 0.91 to 1.02) or all-cause mortality (hazard ratio, 1.05; 95% confidence interval, 0.96 to 1.15) compared with no intervention.

Conclusions

Among older adults with RAASi-related hyperkalemia, RAASi discontinuation is associated with the lowest risk of recurrent hyperkalemia, with no apparent increase in short-term risks for cardiovascular events or all-cause mortality.

Influence of the height of the ribbed-ring dome on the stress state of its frame during the overhang mounting process
Authors: Lebed Evgeny V.
Published: February 2021

The aim of the research. To analyze the stress state of structures of ribbed-ring domes of different heights during overhang erection. The domes have spherical metal frames and a support contour of the same diameter. Due to different heights, the steepness of the geometric shape of the domes changes. The study is devoted to establishing the relationship between the stress state of the frame and the steepness of the dome when mounted. It was investigated how the height of the ribbed-ring dome affects the stress state of its frame during overhang mounting process. Methods. Computer models of design frames of ribbed-ring domes of different heights made of steel I-beams were developed. Based on design models, a sequence of assembly models for incomplete frames was created for different stages of installation. Both for the design and for all installation models of dome frames of different heights, computer calculations were performed for the effect of the load from its own weight. As a result of calculations for all domes and at all stages of installation, deformations and stresses in the meridional ribs were determined, which were compared with the design diagrams. Results. Comparative graphs of deformations of dome frames and diagrams of changes in the degree of use of steel strength in meridional ribs at all stages of mounted installation are obtained. Comparative graphs of installation and design stresses in the meridional ribs on different tiers for all stages of mounted installation are also shown. The assessment of the installation stress states is given, their inevitability and the degree of influence on the stress state of the dome frames are noted.

Experimental studies of reinforced concrete structures of hydraulic structures strengthened with prestressed transverse reinforcement
Authors: Zyuzina Oksana V.
Published: February 2021

Relevance. When repairing hydraulic structures, it is often necessary to face the task of strengthening them. Among the methods of strengthening retaining structures, the most interesting are those that allow to immediately include reinforcement elements in joint work with the structure and carry out work without removing the backfill soil from the rear edge. When choosing repair materials, attention should be paid to corrosion-resistant composite materials, the use of which in hydraulic engineering is not yet standardized, but the scope of their application is expanding every year. The main aim of experimental research is to strengthen the reinforced concrete structures of hydraulic structures, including those with interblock construction joints and transverse cracks, using prestressed transverse reinforcement. Methods. The investigations were carried out on a reinforced concrete model of a beam type reinforced with prestressed transverse reinforcement in the zone of inclined cracks formation. The model was made taking into account the typical tasks encountered during the repair of long-term operating retaining hydraulic structures with open seams and cracks, insufficient transverse reinforcement, low reinforcement coefficient, and initial deflection. Results. The task of strengthening a special reinforced concrete model using prestressed transverse reinforcement was realized. Experimental data were obtained on the nature of deformation and destruction, the opening of interblock construction joints and cracks, and the stresses in the reinforcement. Recommendations are given for strengthening the operated low-reinforced concrete structures of hydraulic structures with interblock construction joints with prestressed reinforcement.

Authors: Khatri Govinda , Lamichhane Govind Prasad
Published: February 2021

Most stone-masonry structures were built at a time when seismic risk was not considered in their design. Recent moderate to strong earthquakes have confirmed the vulnerability of heritage buildings, especially those constructed with unreinforced-masonry materials in various developing countries, worldwide. Proper assessment of the seismic performance and of the potential deficiency of existing heritage structures forms the basis for determining the degree of intervention needed to preserve their heritage values. Analysis of masonry wall confined by wooden band has been carried out using various structural analysis programs. In analysis appropriately considered and introduced link element such as hook, gap and spring at connecting nodes of vertical and horizontal timber elements. The result shows that the traditional floors and spandrels of the existing structure are the vulnerable parts which need strengthening of them to assure the structural members are able to resist seismic vulnerability. The required improvement and strengthening technique in existing building are proposed and better results are marked. The analysis of the modified structure shows considerably improvement in the dynamic characteristics of the buildings and overall structural response of those.

Authors: Jean Paul Vladimir , Elberdov Timur A. , Rynkovskaya Marina I.
Published: February 2021

The article provides an analysis of modern and affordable software systems for modelling shells of complex geometry and the possibilities of using these software systems in 3D printing. Such an analysis made it possible to choose software systems that most accurately allow for the implementation of the 3D modeling method proposed in the article with subsequent printing on a 3D printer. This method is considered in detail on the example of constructing several types of helicoids. The process of 3D modeling of a helicoid is described step by step and is divided into several stages: parametric modeling of a helicoid in SCAD, editing of the resulting model in AutoCAD and its export to a special format for 3D printing. The use of the method of parametric modeling is due to its accuracy and uncompromisingness. With its help, one can accurately judge the type of the built surface. Parametric modeling is the construction of a surface by compiling equations on each axis, i.e. along the x, y, z axes, and for each type of surface there are specific characteristic equations. It is not possible to implement the method of parametric modeling in all software systems; in this connection, certain difficulties arise. The article analyzes the difficulties encountered in 3D modeling of the helicoid and suggests ways to solve them.

Authors: Asoyan Arthur R. , Gorshkov Alexander S. , Israelyan Ani H.
Published: February 2021

A significant proportion of mechanical losses in internal combustion engines accounted for mechanical losses in the cylinder-piston group. Depending on the operating modes of the internal combustion engine, contact interaction in the piston-cylinder pair is possible, which leads to wear of the working surfaces of the resource-determining elements and a decrease in the operational life of the power unit as a whole, in connection with which the reduction of friction losses in the internal combustion engine elements and the piston - cylinder liner coupling in particular is relevant. Both domestic and foreign researchers are engaged in the solution of the above described problems, various profiles of pistons, methods of calculating the parameters of the oil layer are proposed, but the practical state of the issue determines the relevance of research in this direction. The paper considers the possibility of reducing the wear of piston skirts by reducing the contact surface in conjugation and providing an oil film in the friction zone, regardless of engine operating conditions. This opportunity is realized by forming a certain macro profile on the working surface of the piston skirt. The formation of the macrorelief was carried out by means of surface plastic deformation, with the reciprocating movement of a spherical tool on the machined surface.
African Immigrant Teachers Teaching Young EFL Learners: A Racial Discrimination Study
Authors: Ironsi Chinaza Solomon
Published: February 2021

Teaching English language to young learners in an English as a Foreign Language/English as a Second Language context could be challenging especially for African immigrants, as they face varying arrays of challenges ranging from low wages, staff abuse, and other racial discriminations. A lot has been written about racially related issues in our school system yet there are limited works of literature that focus on the challenges of African immigrant English as a Second Language teachers with regards to racial discrimination. To investigate this, a mixed-method research design was used to elicit information from 68 African immigrant English as a Second Language teachers, teaching young English as a Foreign Language learners in 3 countries. The participants were purposively chosen after obtaining written and oral consent from them. A structured questionnaire and semi-structured interview questions were instruments for data collection. Reliability and validity checks were carried out before administering the questionnaire. After analysis, a notable finding was that African immigrant teachers felt unaccepted by the host communities and this made it difficult for the English as a Second Language learners to listen to classroom instructions given by these immigrant teachers. Again, the parents of these learners find it difficult to accept African immigrant teachers teaching their children as they deemed them incompetent to teach them. Other findings of the study were vital in making pedagogical conclusions on racial discrimination issues encountered by African immigrant English as a Second Language teachers. The ways forward for an all-inclusive educational system devoid of ethnic, religious, sexuality and racial issues were suggested.

Published: February 2021

The perceptions and attitudes of educators towards multicultural education are strongly correlated to the manner in which multicultural education is applied. Previous research indicates that culture undeniably has an effect on education, nonetheless, education administrators may not have enough knowledge about multicultural education practices. The aim of the study was to identify the perceptions and interpretations of multicultural teaching from seventeen respondents employed as educators. These educators were all Maltese, teaching Maltese as a second language to adult learners who originated from diverse cultural backgrounds and were living in Malta. The researcher used a qualitative case study design of online interviews to identify the practices that educators perceive to be the best in promoting effective multicultural education. Based on content analysis, the key concepts and activities defined as effective in maintaining multicultural education performance include equality, democracy and justice. Multi-ethnic teaching offers the opportunity to equitably consider and accept divergent viewpoints, which in turn allows proper cohesion not only among students but also educators. Indeed, multi-ethnic education is essential; individuals with varying backgrounds and experiences deserve equality, and community groups need proper representation. This research thus concludes that the majority of teachers agree that practices such as ensuring equality, democracy and justice for all learners regardless of their ethnic, gender, or religious context are of high significance in encouraging inclusion, multicultural education, and student success.
Necessary Amendments
Authors: Stuart Whipps
Published: February 2021

During the passing of the New Towns bill in 1946 the minister for Town and Country planning invoked Moore’s Utopia only to be dismissed, ridiculed and lampooned by opposition politicians in the UK parliament. Whipps’ artistic research takes this moment's crude dichotomy as a starting point to investigate the places that were built and the people who live in them 70 years later. The outcomes (films, exhibitions and publication) allow for the different reading of historical materials from the perspective of memory and community. Whipps’ creates a change to the way we remember and think of ‘new towns’ today by both; representing the stories of people who lived and live in those ‘new’ places and by reflecting upon what happens when idealism and optimism is confronted by bureaucracy and the status quo.

This research utilises historical and archival materials from Milton Keynes City Discover Centre and vintage educational videos from The Open University that were presented alongside newly created photographs, films and personal testimonies. Whipps developed a new body of work that centres around a series of films ‘Necessary Amendments’ (2014 - 2020) supported by community engagement events (e.g “Cycle Tour” around Milton Keynes public art displays, 2018), new photographic and film material from the sculpture garden created by a Harlow New Town architect Sir Fredrick Gibberd, and commissioned writing by Dr Honor Gavin (The University of Manchester).

His findings in a form of films, contemporary art exhibitions, public talks and publications were supported by MK Gallery, The Open University and the University of Hertfordshire. The project was exhibited nationally in MK Gallery, and internationally in CURRENT Athens. “Necessary Amendments: Homes for the People” film was commissioned and exhibited as part of New Geographies (funded by ACE). Whipps published a peer-reviewed paper in ‘Art & the Public Sphere’ journal (2017).
AHOK AND BLASPHEMY CASE IN KOMPAS AND REPUBLIKA ONLINE MEDIA: A CLASH OF IDEOLOGIES
Authors: Saputra Muhammad Beni
Published: February 2021

Ahok's speech in Kepulauan Seribu was viral on the internet. The speech put the ethnic Chinese Christian Jakarta governorÂ into a national spotlight. Mass media then sought to interpret Ahok's speech by framing its content. Using Robert Entman's framing theory, this paper analyzes online media framing of Republika and Kompas on Ahok and a blasphemy case involving him. Content analysis of the news articles published by the two online media shows that the framing of Ahok and the blasphemy case differ in reporting and focus. KompasÂ Online mostly reported positive news about Ahok, while Republika Online demonstrated a different pattern of framing. On the blasphemy case, Kompas Online focused on defense, whereas Republika Online emphasized that Ahok had insulted Islam and had to be jailed. These differences are manifestations of an ideological clash between Kompas and Republika.
