Increased Expression of Tubulin A, Cyclin B1, and Ki67 May Associate with Cell Death Mechanism Caused by Noncontact Electro Capacitive Cancer Exposure in vitro
Authors: Sahudi Abdul Mujib
Published: April 2021

Background: Noncontact Electro Capacitive Cancer Therapy (ECCT) is a novel treatment modality incancer that uses low-intensity intermediate-frequency alternating electric field. A previous study has reportedECCT could induce cell death in cancer cells, but the molecular mechanism underlining this process remainsunclear. Therefore, this study aims to uncover the molecular mechanisms of the pathology induced by thedevice and to determine whether Tubulin A, Cyclin B, and Ki67 can serve as biomarkers for this exposure.Methods: This study was an in vitro laboratory experiment with Completely Randomized Block Design.Two different types of cancerous cell lines were used in this study: oral squamous cell carcinomas and Helacells. In addition, non-cancerous cell line, bone marrow mesenchymal cell, was also subjected to the electricfield produced by ECCT. All three cell lines were divided into two groups: the ECCT-exposed group andthe control group. After exposure, the protein expression of Tubulin A, Cyclin B, and Ki-67 was examinedusing immunocytochemistry staining.Results: The results showed that the number of Tubulins A, Cyclin B1, and Ki-67 expression wassignificantly higher in ECCT-exposed group than in the control group (p<0.05). Increased expression oftubulin A indicates a disruption to microtubule polymerization, an increase in Cyclin B expression indicatesmitotic arrest or incomplete mitosis, whereas the increase of Ki-67 expression occurs when cells stop in themetaphase phase (mitotic arrest).Conclusion: It could be concluded that increased Tubulins A, Cyclin B1, and Ki-67 expression may associatewith the death cell mechanism induced by exposure to Noncontact Electro Capacitive Cancer devise.

By April 1st 2020, the confirmedcases were over 800,000 around the world with over 40,000 fatalities. Individuals with cancer are morevulnerable to COVID-19 impact because of compromised health-status.Methods A comprehensive search method was applied by searching the google scholar using the keywordsto select eligible studies to be included in the reviewResults The findings showed that patients with cancer, especially thoracic malignancies that wereinfected with COVID-19 infection during the hospital stay developed severe cardiorespiratory symptomsthat warranted use of a mechanical ventilator. The cancer patients with COVID-19 had increased rateof hospitalization and a poor outcome as well as a higher risk of mortality when compared to healthyindividuals. It is recommended that cancer patients taking anti-tumour drugs should undergo early screeningfor COVID-19 because the anti-tumour drugs also suppress the immune system. Hence, their dosage shouldbe regulated appropriately in case of COVID-19 co-infection.Conclusion. In risk-mitigation pandemic scenario in COVID-19 period, efforts should be made not tocompromise the prognosis of cancer in these patients by adhering to treatment guideline.

The paper examines financial architecture in the context of digital globalization. The current state of financial architecture as a science of creating financial architecture, the nature, specificity, principles of development of financial systems of different levels, based on unity, general patterns of their development and regulation. The current stage of development of national financial architecture is characterized by significant contradictions. On the one hand, the national-state form of its organization is preserved, on the other hand, the possibilities of national financial policy are limited due to the growing importance of international financial instruments, increasing international capital and strengthening the role of international financial organizations. The nature of relations and interrelations of national financial architecture is changing – its openness and interdependence is increasing, the scale of chain reactions is increasing, according to which negative phenomena spread from one class of financial assets, types of financial institutions, financial market segments to others. It is accepted that financial architecture should achieve a specific goal, and its results should be measured by performance indicators that have certain specifics at different economic levels. The changes characterizing the development of the financial environment are outlined, the necessity of forming a new financial architecture taking into account the existing globalization processes and challenges is revealed. The directions of ensuring successful realization of means of digitalization of financial infrastructure, financial market are offered. We can say that the development of economic systems, technologies, real markets directly depends on the depth of financial architecture of the country's financial architecture, is the ability of a set of banking and non-banking financial institutions to effectively distribute and redistribute the movement of financial capital.

Authors: Mujica-Sequera Ruth M.
Published: April 2021

Al reflexionar sobre el término alfabetización, los individuos de inmediato se imaginan a un sujeto sin competencias mínimas de lectoescritura. El presente artículo se concibió con el fin de llevar a cabo un estudio sobre la importancia de generar conocimiento en el siglo XXI. El cual, surgió del antagonismo, de que las publicaciones científicas solo deben ser publicadas por expertos. Para el emprendimiento del estudio, se sostuvo una aproximación multidisciplinar, donde se incorporaron diferentes perspectivas, así como, concepciones sobre las Ciencia Sociales, psicología, participación ciudadana, social y pedagógica. Se realizó una investigación cualitativa de enfoque fenomenológico-hermenéutico, donde se entrevistaron a diez (10) actores sociales del Taller Internacional de Redacción de Artículos Científicos, para luego estructurar, codificar hasta categorizar los resultados. Este recorrido epistémico permitió un acercamiento teórico, centrado en la alfabetización de los actores sociales, en calidad de, generar conocimiento a través de educación científica significativa. Partiendo de la voz de los actores sociales, se estableció el desgarramiento de las cadenas burocráticas de cada editorial, debido a que el conocimiento es más accesible en la era digital. No obstante, el analfabetismo se ha propagado vertiginosamente, incitada por los grupos de la vieja escuela, creando confusión en el qué de los sucesos, para expandir su hegemonía. Por ende, alfabetización científica (AC) no solo está centrada en el factor común de la actividad científica del cómo, sino también en el fortalecimiento de la ciencia a través de las Instituciones de Educación Superior, grupos de investigación, organizaciones y empresas educativas.

El uso de la tecnología dentro del espacio educativo tiene un papel muy importante para el desarrollo de materiales o recursos didácticos innovadores. A pesar de los grandes cambios que tiene consigo la tecnología se puede cuestionar a instituciones educativas fiscales del ministerio de educación del Ecuador donde aún es evidente el desconocimiento en relación con el uso de recursos educativos digitales en los procesos de inclusión de personas con discapacidad sensorial. Por tal motivo, la presente investigación originó la integración de las tecnologías de la información y comunicación TIC como recurso didáctico en los procesos comunicativos y de enseñanza-aprendizaje que se generan en la comunidad educativa.  Es así como el proceso de investigación se utilizó el enfoque mixto, donde participaron 35 docentes de diferentes instituciones educativas a quienes se les aplicó como instrumentos encuesta basada en escala de LIKERT, una entrevista, como, además la observación directa y revisión bibliográfica. Dentro de los resultados obtenidos se evidencio una diversidad de recursos tecnológicos que se pueden utilizar en los procesos de inclusión educativa entre los que se puede mencionar los pictogramas digitales, infografía y aplicaciones móviles, los cuales permiten fortalecer el proceso comunicativo y de enseñanza-aprendizaje de la comunidad educativa. En consecuencia, se puede aseverar que la incorporación de tecnologías en las comunidades educativas permite fortalecer los procesos de enseñanza aprendizaje y a su vez masifican los procesos de inclusión educativa.

The petroleum industry in Algeria takes a predominant place in the econo-my. This industry amplifies the environmental contamination and affects microbial diversity of soils. Bioremediation is a cost-effective and efficient process for removing hydrocarbon pollutants. The aim of the study was to isolate cultivable telluric bacteria and to assess their potential as bioremedi-ation agents against the contamination of petroleum hydrocarbons. Crude oil polluted soil samples were taken from different oil refinery in Algeria. Elemental analysis was determined by inductively coupled plasma optical emission spectrometry (ECP-OES). The screening of bacteria degrading hy-drocarbons was studied with oil spreading technique on mineral salt medium (MSM agar) supplemented with crude oil as the only carbon source and en-ergy for direct visualization of clear zones on agar plates. Among the isolates, ten were selected for their degradation potential based on their large clear zone (from 0.5 to 3.2 Cm) for phenotypic and genotypic characterization. Molecular identification was performed by sequencing the gene encoding 16s rRNA. The comparison of sequences with GenBank database showed similarity with different strains Aeromonas hydrophila, Stenotrophomonas maltophilia, Enterobacter xiangfangensis, Pseudomonas aeruginosa, Serratia marcescens, and Raoultella sp. These results are significant for the applica-tion of these isolates at the environmental scale in bioremediation of pollut-ed soils.

Published: April 2021

Despite recent progress and therapeutic advances made in the field of breast cancer. This pathology remains the main cause of female cancer and repre-sents a real major public health problem in Algeria as well as globally. The objective of this study, carried out in the Algerian West, was to assess the epidemiological profile of breast cancer in the Oran region through the pa-tients recruited in the Regional Military Hospital of Oran University (HMRUO), then to determine the clinical, biological and pathological factors that conditioned the overall survival. Among the methodological approaches used in our study were classical histology, immunohistochemistry and fluo-rescence in situ hybridization (FISH) techniques of different biological mar-kers (HER2, hormone receptors (RE and RP). The analysis is carried out using the Epi Info software version 3.4 on all invasive cancers. In a retrospective study of 265 patients with breast cancer over 3 years (February 2017–October 2019), we examined the epidemiological profile of breast cancer to determine the impact of biological and prognostic factors on survival over 3 years. Invasive tumours were found in 95.5% of the women. The average tumour size was big [3.6 (SD 2.6) cm] and only 14% were histological grade I. Overall survival at 3 years was only 49% for the RE–/RP–/HER2– subtype and 75% for the RE–/RP–/HER2+ subtype, while it was 96% for the RE+/RP+/HER2– subtype. The young age, large tumour size and high histological grade in our population suggest a lack of awareness of women about breast can-cer.

Allium section Rhizirideum is reviewed for South Korea and neighboring northeastern China based on critical observation of wild populations and herbarium materials. Species delimitations are re-evaluated on the basis of morphological and somatic chromosome numbers, resulting in the recognition of five species. Allium dumebuchum from Ulleungdo Island, South Korea, is described as a new species. This species is most similar to A. senescens due to its habits, but is clearly distinguished particularly by its rhomboid scapes in cross-secion, light purple perianth color, entire and narrowly triangular inner filaments, and flowering season from late September. One previously recognized species is placed into synonymy: A. pseudosenescens (under A. senescens). Photographs and a key to species of Allium section Rhizirideum in South Korea and northeastern China are provided in addition to information on nomenclatural types, synonymies, chromosome numbers, distribution, and specimens examined.

Scène et hors-scène : la tragédie grecque entre théâtre et cinéma
Authors: Brunet Philippe
Published: April 2021

On tente ici un essai de dramaturgie comparée : de la tragédie grecque en tant que texte à sa mise en scène, fondée sur une opposition entre espace visible et espace hors scène. Ce hors-scène du passé ou des actions lointaines est parfois médié par l’intrusion de l’image vidéographique. Que devient la tragédie, lorsque la possibilité d’une narration double, articulant la scène et le hors-scène, devient l’enjeu d’une proposition cinématographique ? C’est ce que tente d’expliquer Philippe Brunet à travers ses propres mises en scène théâtrales d’Antigone abyssinienne (2010), d’Œdipe roi (2014), et expériences de cinéma, dont le Double destin du roi Œdipe, en voie d’achèvement en 2020.

Published: April 2021

This study aims to explore the inclusion of microfibre in fine recycled aggregate (FRA) mortars under dynamic impact load. A 12-mm-diameter Split Hopkinson Pressure Bar (SHPB) was employed to test the impact of a recycled mortar with a single and hybrid fibre system and to determine potential improvements in its dynamic mechanical properties. In recycled mortar production, two microfibres with different sizes and types, namely, polypropylene and nylon, were added whilst keeping the amount of microfibres at a volumetrical fraction of 0.6%. An impact loading test was conducted by using the striking bar of SHPB at impact speeds of 2, 4 and 6 m/s. The effects of fibre on failure mode, tensile curve, compressive strength and dynamic increase factor (DIF) were then analysed. Experimental findings show that the improved mortar fibre mix has superior quasi-static and dynamic compression power compared with the reference mortar mix. Meanwhile, compared with the single fibre mix, the hybrid fibre mix is more effective in enhancing the dynamic compressive ability of the recycled mortar. The recycled-hybrid-fibre-enhanced mortar showed lower DIF values compared with the reference mortar, and the inclusion of fibre reinforcement can reduce the fragmentation of the recycled mortar mix after being subjected to impact.
[Considerations on an alleged specimen of a Tingitan raven Corvus corax tingitanus Irby, 1874 from the Arrigoni degli Oddi Collection]
Authors: Fraticelli Fulvio , Marangoni Carla
Published: April 2021

[The Common raven Corvus corax is an holoartic species, divided into 12 subspecies, three of which are present in Italy. Based on the most recent systematics, the sub-specific attribution of the Italian populations has been discussed. In the Arrigoni degli Oddi’s bird collection a specimen from Sardinia was attributed to C. c. tingitanus, a subspecies of the North Africa coasts and accidental in Italy. Some biometric parameters have been measured and compared with the literature data. This work allowed to review the attribution of this specimen by Arrigoni degli Oddi and report it to C. c. hispanus.]

Plastic Screen Versus Aerosol Box as a Barrier During Endotracheal Intubation
Authors: Ponnappan Karthik T. , Dhingra Udit , Yadav Anil Yogendra , Sam Amal Francis
Published: April 2021

Background:

The severe acute respiratory syndrome coronavirus-2-2019 pandemic has posed significant challenges and barrier devices such as aerosol/intubation box, intubation tent, and intubation screen have been widely used during endotracheal intubation by the clinicians without any definite proven benefit. The initial experience at our institute with the intubation box posed some difficulties leading to failed intubations. Hence, as an alternative, we switched to a transparent plastic intubation screen that is likely to provide better vision and space during intubation. We evaluated the impact of intubation box and plastic screen on intubations in this simulation-based crossover study.

Materials and Methods:

Ten anesthesiologists performed 90 intubations in an operating room on a Laerdal® adult airway management trainer. Each participant performed 9 intubations, 3 without any barrier and 3 each with intubation box and plastic screen. The primary outcome was intubation time; secondary outcomes included first-pass success and breaches to personal protective equipment.

Results:

Intubation time with no barrier was significantly shorter than with the intubation box (median interquartile range [IQR]: 25 [22–28] vs. 40 [30–51] s, P < 0.001) and with the screen (median [IQR] 29 [25–35] s, P = 0.015). The intubation time was significantly lesser with the screen compared to the box (P = 0.023). The first-pass success was 86.66%, 96.66%, and 100% in the box, screen, and no barrier groups, respectively.

Conclusion:

In comparison to an intubation box, the transparent plastic screen decreases intubation times and has greater operator comfort. These devices require further evaluation for patient safety.
Single-triangle technique for congenital ptosis repair with a frontalis sling in blepharophimosis patients
Authors: Mehta Anuj , Naik Mayuresh , Agarwal Siddharth
Published: April 2021

The purpose of this study was to describe the single-triangle technique for congenital ptosis repair with a frontalis sling in blepharophimosis patients. The single-triangle technique was used in 40 eyes of 20 patients of blepharophimosis syndrome. The center point of the lid is marked. The desired base length is calculated depending on the available horizontal fissure width. Two marks are inked 2 mm above the lid margin, equidistant from the central mark. A single brow mark is placed in such a way that it is directly above the center point of the lid. These are now joined to complete the triangle. In blepharophimosis patients, the mean preoperative margin reflex distance (MRD1) was 1.0 ± 1.1 mm which increased to 4.1 ± 1.6 mm after surgery. The MRD1 increased by 3.1 ± 1.7 mm. Cosmetic outcome was graded with a score of 0, 1, or 2 to indicate poor, good, and excellent results, respectively. Out of the 40 eyes that were operated, 33 eyes had a score of 2, 5 eyes had a score of 1, and 2 eyes were scored 0. The single-triangle technique has several advantages over both the Fox pentagon technique and modified Crawford technique in severe blepharophimosis patients. It is not only a much simpler procedure to perform but also has a better control over the curvature of the lid without any central focal notching, thus providing better cosmesis and esthetic results.
External balance sheets of emerging economies: low-yielding assets, high-yielding liabilities
Authors: Akyüz Yılmaz
Published: April 2021

The new millennium has witnessed a rapid expansion of external balance sheets and significant changes in the capital, currency and sectoral compositions of foreign assets and liabilities of emerging economies. These have created new channels of transmission of global financial shocks and amplified the susceptibility of the value of their outstanding stocks of gross foreign assets and liabilities to global financial conditions, leading to sizeable wealth transfers between emerging and advanced economies. They have also resulted in significant income transfers in view of negative yield differentials between their gross external assets and liabilities. Altogether, such transfers to advanced economies are estimated to have reached 2.3 per cent of the combined GDP of the G20 emerging economies per annum during 2000–2016.
Expectations and exchange rates in a Keynes–Harvey model: an analysis of the Brazilian case from 2002 to 2017
Authors: Lima Leandro Vieira Araújo , Terra Fábio Henrique Bittes
Published: April 2021

This paper investigates the statistical relationship between the future expectations of the exchange rate and GDP growth and the current nominal exchange rate in Brazil during the period 2002–2017. The theoretical framework on which the paper is based is a decision-making model grounded in Keynes (1921; 1936) and Harvey (2006; 2009a), from which the paper's empirical model emerges. This model is tested empirically with autoregressive distributed lag models to identify short- and long-term statistical relationships in time series. The empirical estimations suggest that expectations of future changes in both the exchange rate and GDP growth have a statistically significant relationship with the current nominal exchange rate in Brazil, just as the Keynes–Harvey model predicts.
Applicability of IFRS in Vietnam stock exchange listed companies: Perspective from Theory of Planned Behavior
Authors: Diep Nguyen Thi Ngoc
Published: April 2021

The research, based upon data collected from 273 enterprises, uses the Theory of Planned Behavior (TPB) to identify and estimate the degree to which factors the ability to apply IFRS in listed non-financial enterprises has been affected. Through Exploratory Factor Analysis (EFA) and multivariate linear regression approach, the research proves that there are four factors placing impacts on IFRS adoption in listed companies in Vietnam. Those are management’s attitude, costs, economic integration, accounting staff’s knowledge and skills. The research results are the foundation for businesses to be fully prepared for the favorable and successful application of IFRS. In addition, the results of this study are also useful references for policy-making agencies and professional associations in promoting IFRS application in Vietnam the next time.
Trade and income distribution: Is natural disaster an actor?
Authors: Tam Doan Ho Dan , Vy Nguyen Phuc Phuong , Tham Nguyen Thi Xuan , Thang Hoang Thi Ngoc
Published: April 2021

This paper examines the impact of trade on household income inequality (measured using Gini index) under the condition of disaster (measured using various proxies). The paper uses panel regression on a balanced dataset of 48 countries for 2011-2017 to estimate the impacts, with data combined from World Development Indicators, World Income Inequality Database, and World Risk Report. Various robustness checks are also carried out. The results show that trade does not have any impact on inequality on its own. However, with the existence of disaster, the increase of trade leads to higher income inequality. Finally, the effects are stable when disaster is measured using Composite index or Vulnerability component but becomes not clear when using Exposure component, suggesting that it is vulnerability the main factor that moderates the impact of trade on income inequality.
Nguồn thông tin, lòng tin và sự lựa chọn nơi mua rau: Nghiên cứu ở Thành phố Hồ Chí Minh
Authors: Thanh Lê Thị Tuyết
Published: April 2021

Sau một thời gian dài không thay đổi trong thói quen chọn nơi mua rau hay thực phẩm nói chung, người tiêu dùng Thành phố Hồ Chí Minh (TP.HCM) thời gian gần đây đã bắt đầu dịch chuyển mạnh mẽ từ các kênh truyền thống sang các kênh hiện đại như siêu thị hay siêu thị mini. Một trong các nguyên nhân thay đổi là vấn đề thực phẩm bẩn mà cụ thể là rau tại các kênh phân phối truyền thống không đảm bảo an toàn vệ sinh thực phẩm. Nghiên cứu này phân tích tác động của (1) lòng tin đối với người bán và quản lý nhà nước về VSATTP và (2) kênh tìm kiếm thông tin về VSATTP đến tần suất mua rau tại các kênh bán lẻ. Số liệu tự điều tra từ 254 người mua rau tại TP.HCM được phân tích bằng mô hình Seemingly Unrelated Negative Binomial. Kết quả nghiên cứu cho thấy những người tin ở chính sách quản lý VSATTP có xu hướng chọn mua rau ở chợ nhiều hơn và do đó cải thiện chính sách quản lý an toàn thực phẩm đối với rau sẽ giúp cải thiện hoạt động của chợ truyền thống. Ngoài ra những người tìm hiểu thông tin qua truyền thanh truyền hình và báo chí có tần suất mua rau ở siêu thị cao. Cửa hàng RAT có thể nhờ kênh truyền miệng để tăng lượng khách hàng vì những người tìm hiểu thông tin qua kênh truyền miệng có xu hướng mua rau ở cửa hàng RAT nhiều hơn.
