ISOLATION OF POTENTIAL ANTIMICROBIAL METABOLITE FROM ENDOPHYTIC BACILLUS AMYLOLIQUEFACIENS DL06 OF CARNIVOROUS PLANT DROSERA BURMANNII VAHL.
Authors: CHAUDHURI MADHUBANTI , AK PAUL , PAL ARUNDHATI
Published: January 2021

Objectives: Exploitation of bacterial endophytes for production of antimicrobial substances has led to the discovery of novel natural metabolites of diverse chemical nature. The present study focuses attention toward optimization of cultural conditions for production of antimicrobial compound(s) by an endophytic bacterium DL06 followed by its extraction and partial purification.

Methods: The leaf endophytic bacterium Bacillus amyloliquefaciens DL06 (GenBank Accession no. MK696415, Microbial Culture Collection Accession no. 4186) isolated from carnivorous plant Drosera burmannii has been identified as a potent producer of antimicrobial metabolite following agar cup assay against several test bacterial and fungal strains. Cultural conditions for production of antimicrobials were optimized by “one variable at a time” method. The active fraction was isolated and purified partially using solvent extraction, thin-layer chromatography, and high performance liquid chromatography (HPLC) analysis.

Results: B. amyloliquefaciens DL06 produced maximum antimicrobial compound in tryptic soy broth and Davis–Mingioli’s medium when grown under shake culture. Production of the antimicrobial metabolite has been optimized for the inoculum density, aeration, temperature, pH as well as carbon, and nitrogen sources. The antimicrobial metabolite was extracted from the cell-free culture filtrate in butanol and partially purified by silica gel column chromatography and HPLC.

Conclusions: The antimicrobial metabolite, tentatively identified as quercetin showed broad spectrum bioactivity affecting several fungi and a number of Gram-positive and Gram-negative bacteria.

This study's objectives were to identify how subtle differences in ultimate pH relate to differences in pork quality and to understand how early-postmortem glycolysis contributes to variation in ultimate pH. The hypothesis was that elements in early-postmortem longissimus thoracis et lumborum proteome and metabolome could be used to predict quality defects associated with pH decline. Temperature and pH of the longissimus thoracis et lumborum were measured at 45 min, 24 h, and 14 d postmortem. Quality measurements were made after 14 d of aging. Groups were classified as normal pH (NpH; x̄ = 5 . 59 [5.53–5.67]; NpH, n = 10) and low pH (LpH; x̄ = 5 . 42 [5.38–5.45]; LpH, n = 10) at 14 d postmortem. Metabolites from 45 min postmortem were identified using GC-MS. Relative differences between proteins were quantified with two-dimensional difference in gel electrophoreses, and spots were identified with MALDI-MS. Western blot analyses were used to measure phosphofructokinase, peroxiredoxin-2, and reduced and non-reduced adenosine monophosphate deaminase-2 at 45 min and 14 d postmortem. Ultimate pH classification did not affect 45-min-postmortem pH (P = 0.64); 14-d pH was different between groups (P < 0.01). NpH had less purge loss (P < 0.01), was darker (P < 0.01), had lower star probe (P < 0.01), and had less intact day-7 desmin (P = 0.02). More pyruvate (P = 0.01) and less lactate (P = 0.09) was observed in NpH, along with more soluble lactate dehydrogenase (P = 0.03) and pyruvate kinase (P < 0.10). These observations indicate that differences in enzyme abundance or solubility may produce more pyruvate and less lactate. Fructose 6-phosphate was more abundant (P = 0.08) in the LpH group, indicating that phosphofructokinase may be involved in glycolytic differences. Furthermore, greater abundance of heat shock proteins, peroxiredoxin-2 (P = 0.02), and malate (P = 0.01) early postmortem all suggest differences in mitochondrial function and oxidative stability that contribute to quality differences. These results show that even subtle changes in ultimate pH can influence pork quality. The proteome and metabolome at 45 min postmortem are associated with variation in the extent of pH decline.

Trabajo de campo virtual en investigación cualitativa
Authors: Hamui Sutton Liz , Vives Varela Tania
Published: January 2021

Las restricciones impuestas por la contingencia sanitaria y el riesgo de contagio han influido en la movilidad y las modalidades de las interacciones. El objetivo de este trabajo es explorar la pluralidad de opciones para la cogeneración y recabación de material en la fase de trabajo de campo en proyectos de investigación cualitativa. Se transita por los componentes del diseño metodológico (sujetos participantes, recursos tecnológicos disponibles, acuerdos previos al encuentro y plan de análisis) para reflexionar sobre las transformaciones que involucra la modalidad virtual. Enseguida se discute la manera en que el entorno virtual abre nuevas posibilidades para investigar y procesar datos. La mediación tecnológica abre canales de comunicación que convocan a una gran diversidad de perfiles con características interseccionales diversas. También se pluralizan los formatos para procesar y presentar los hallazgos de investigación como videos documentales, infografías, fotomontajes, comics, animaciones, textos con distintos géneros literarios, entre otros. El cambio en las estrategias en campo, afecta a nivel epistemológico, pues el conocimiento se construye de otra manera, por medio de narrativas situacionales y experienciales compuestas de conocimientos, emociones y descripciones relacionales diacrónicas y sincrónicas, expresados en el espacio virtual. No obstante, las consideraciones éticas del trabajo de campo en la modalidad virtual se mantienen. Ante la nueva normalidad, existen tres respuestas ante los desafíos para la recabación de información o co-construcción de datos: mantener en la medida de lo posible el proyecto original y ver la manera de propiciar encuentros físicos con sana distancia y otras medidas higiénicas. La segunda respuesta es trasladar los encuentros presenciales al espacio virtual, y la tercera es pensar nuevas modalidades investigativas y crear narrativas en formatos innovadores utilizando tecnologías versátiles.

The translation from Arabic into Indonesian on the Islamic field has its long history. However, researches on the subject are a little bit rare. Therefore, the study of the item using a modern approach is required. This research described the use of amplification and descriptions techniques in the translation of Arabic phrases in the reading of Matan al-Ghayah wa al-Taqrib by Ahmad Ma'ruf Asrori. Besides, this paper aimed to describe the quality of the text that is seen from the aspect of readability. This research used a qualitative analysis combined with a quantitative data approach. The data were selected and classified based on procedures of translation techniques. The results showed that based on the amplification techniques there were 35 data in Matan al-Ghayah wa al-Taqrib found 35 which can be divided into four Arabic phrases based as follows: 1) 'atfy phrases are 12 data, 2) idhafy phrases are 13 data, 4) syibhu al-jumlah phrases are 5 data, and 5) adjective phrases are 5 data. Whereas in the description technique, the researchers found 31 data divided into five Arabic phrases based on their constituent elements, namely the 'atfy phrase 12 data, idhafy phrase 12 data, ‘adady phrase 3 data, syibhu al-jumlah phrase 3 data, and adjective phrase 2 data. From the translation quality, it showed that the use of these two techniques could be seen from the assessment of the readability aspects of 42 respondents. It rated 52% high readability on the amplification technique, and 56% high readability on the description technique.

Elementary school students in general are still learning traditionally. Especially elementary school students learn entrepreneurship to train to create value innovations that are valuable independently. However, in this 4.0 era, many elementary students still run entrepreneurship in the traditional way by producing physical works, this is certainly because elementary school students do not experience development with the interference of technology. What should be elementary school students should have started to know technology early on. So, the purpose of this research is to empirically discuss how elementary school students are able to learn entrepreneurship digitally from an early age. With the iLearning method elementary school students are able to develop with a blend of technology 4.0 to create innovative results visually. The presence of the SEP (School Enrichment Program) system which is a bridge for elementary school students in learning entrepreneurship through learning so that they can improve their quality early on. In addition, the gamification techniques that exist in the system make elementary school students significantly more motivated in entrepreneurial learning. The sample data test results show that Cronbach's Alpha 0.702> 0.6 on the SEP system is significantly reliable.

Defining quantum divergences via convex optimization
Authors: Fawzi Hamza , Fawzi Omar
Published: January 2021

We introduce a new quantum Rényi divergenceDα#forα∈(1,∞)defined in terms of a convex optimization program. This divergence has several desirable computational and operational properties such as an efficient semidefinite programming representation for states and channels, and a chain rule property. An important property of this new divergence is that its regularization is equal to the sandwiched (also known as the minimal) quantum Rényi divergence. This allows us to prove several results. First, we use it to get a converging hierarchy of upper bounds on the regularized sandwichedα-Rényi divergence between quantum channels forα>1. Second it allows us to prove a chain rule property for the sandwichedα-Rényi divergence forα>1which we use to characterize the strong converse exponent for channel discrimination. Finally it allows us to get improved bounds on quantum channel capacities.

Significado de La Alianza en el pueblo de Israel.
Authors: Esquivel Monge Gerardo
Published: January 2021

Es notorio y sorprendente el manifiesto interés que en los últimos 20 años especialistas de las Sagradas Escrituras han mostrado por el estudio de la Alianza entre Yahvéh y el pueblo de Israel. En este sentido, el presente ensayo reconoce que la alianza exódica es el hecho fundamental del pueblo de Israel, trata de desentrañar los fundamentos y consecuencias socio-teológicas de este hecho, y destaca que Yahvéh, por medio de la hierática figura de Moisés, libera al pueblo de la esclavitud de Egipto. En esa liberación, Yahvéh se revela como padre que defiende a los oprimidos y exige justicia.Los profetas Amós, Isaías, Jeremías, Miqueas, entre otros, en nombre de la alianza, amonestan al pueblo para que reoriente sus prácticas sociales. Al final se señala que la situación social, que viven los pueblos del tercer mundo, encuentra en la alianza una rica veta para la reflexión y esperanza de liberación.
Desarrollo histórico del Derecho Comercial.
Authors: Torres José Luis
Published: January 2021

En el presente artículo se intenta realizar un análisis histórico- jurídico de la evolución del Derecho Comercial desde fines de la Edad Media hasta el presente. Se hace hincapié en que el Derecho Comercial es una categoría histórica  que responde a una realidad social, modificada por circunstancias económicas, sociales y políticas. Con el proceso de transición del feudalismo al capitalismo, surgen nuevas instituciones jurídicas del Derecho Comercial como la banca, la bolsa, el cheque, el pagaré, la letra de cambio, que contribuyen a potenciar el desarrollo de los nuevos estados nacionales europeos. Se analizan las nuevas concepciones jurídicas del Derecho Comercial, tales como: la tesis subjetiva,  objetiva, la teoría de la empresay los nuevos enfoques del Derecho Comercial posmoderno.

Endemic corporate responsibility dimensions in the developing economy: An exploratory study
Authors: Gokarna Poojaa , Krishnamoorthy Bala
Published: January 2021

The current understanding of corporate social responsibility (CSR) and its associated dimensions have majorly been developed by western researchers (Xu & Yang, 2010). An exhaustive study of CSR as a concept based in the specific socio-cultural settings of India is imminent (Mohan, 2001). Hence, this research is predominantly intended to identify the endemic CSR dimensions as well as the actions that constitute these dimensions for organisations based in India. The official company website is the common communication medium for publishing information about CSR. Therefore, inductive research was conducted for twenty-seven corporate websites of companies in India using qualitative content analysis. Nine dimensions of CSR along with the actions that constitute these dimensions were identified. The dimensions are economic dimension, environment protection, ethical consideration, employee, consumerism, community development, legal, stakeholder expectation and philanthropy. Thus, this study helps develop knowledge and understanding about CSR within a specific context, i.e., India. This research will lend a holistic perspective for creating a CSR strategy for an organisation
The level of perception, awareness, and behavior on intellectual property protection: A study of the emerging country
Authors: Tam Le Thi Thanh , Thai Hoang Dinh , Hai Pham Thi Thanh , Tuan Tran Diep , Thanh Tran Chi
Published: January 2021

Emerging economies are facing problems in the administration and compliance with intellectual property protection in their countries. The IP term is now much more familiar to the public, but it is not well understood completely in a lawful way. The public is misinformed (or, at best, under-informed) about IP leading to higher levels of infringement as well as reducing the use and value of IP. Our study aimed to determine the level of perceptions, awareness, and behavior (PAB) on IP Protection of the medical technology students with the cross-sectional on-line survey on 795 students by electronic European Union Intellectual Property Office (EUIPO) questionnaire. The overall level of PAB was very high, greater than three quarters. The demographic factors related significantly to right PAB on IP protection were sex (female higher than male) and residency (other cities higher than Ho Chi Minh City). Only the awareness had the covariance with the behavior in structural equation modeling (SEM) model with a significant coefficient of 0.55. We should focus on an education program to increase the right awareness, then it would improve the right behavior on intellectual property protection in students who are living in the emerging countries.
Dual aortic aneurysms with coronary artery and multiple cerebrovascular stenoses
Authors: Hashimoto Masafumi , Mogi Kenji , Sakurai Manabu , Tani Kengo , Ito Shuntaro , Takahara Yoshiharu
Published: January 2021

Simultaneous thoracic and abdominal aneurysms comprise approximately
10–20% of all cases of aortic aneurysms. Whether simultaneous or
staged therapy can be used to treat multilevel aortic aneurysms remains
controversial. Herein, we report the case of a 79-year-old woman with
both huge abdominal and saccular thoracic aortic aneurysms who was
referred to our hospital. Multiple stenotic lesions were observed in the
major cerebral arteries; moreover, triple-vessel disease was observed on
the coronary angiogram. Although this case required immediate primary
surgery, cardiopulmonary bypass was difficult due to multiple stenoses
in the cerebral arteries. We performed simultaneous surgery with total
debranching thoracic endovascular aortic repair, endovascular aortic
repair, and off-pump coronary artery grafting. Total debranching
thoracic endovascular aortic repair is useful for avoiding neurological
complications in cases where cardiopulmonary bypass is difficult.
Furthermore, it helps devise an intraoperative cervical branch
reconstruction method.
Effect of COVID-19 on air pollution and respiratory viral infection of children in South Korea
Authors: Park Hyung Kyu , Shim Jung Yeon , Jung Hye Lim , Shim Jae Won , Kim Deok Soo , Kwak Ji Hee , Yang Aram , Sol In Suk
Published: January 2021

Background: Air pollution can be a risk factor for respiratory viral
transmission and infection. The COVID-19 outbreak in 2020 may have
affected ambient air pollution levels. Therefore, this study aimed to
investigate air pollution levels and respiratory virus infection rates
before and after the COVID-19 pandemic as well as determine
relationships between these factors. Methods: The daily mean temperature
and concentrations of air pollutants (PM2.5, PM10, O3, NO2, CO, and SO2)
in five metropolitan cities in South Korea were collected for the months
of February to May from 2015 to 2020. Results of 14 respiratory viruses
isolated using polymerase chain reaction in children with upper or lower
respiratory tract infections were gathered during the same period.
Trends of respiratory virus infection, temperature, and air pollutant
level from February to May for six years were evaluated and possible
relationships between respiratory virus infections and ambient air
pollutant levels were assessed. Results: Most air pollutants exhibited
significantly decreasing trends in 2020 compared to the years before
COVID-19. There were no differences in temperature. Adenovirus,
bocavirus, metapneumovirus, parainfluenza virus 3, and rhinovirus were
the most frequently detected viruses from February to May from 2015 to
2019, and infection rates dropped significantly in 2020. The
concentration of ambient O3 was associated with rhinovirus infection in
hospitalized children (aOR [95% CI], 1.028 [1.002, 1.055]).
Conclusions: After the COVID-19 outbreak, ambient air pollution levels
and respiratory virus transmission decreased in the pediatric population
of South Korea.

Prevalence of Diabetes Mellitus in Selected Turkish Prisons and Exploration of Related Factors
Authors: KASIM İsmail , Şahin Murat
Published: January 2021

Background: It’s known that prisoners have worse physical and mental
health conditions. Objective: This study aims to determine the
prevalence of DM in the selected Turkish prisons. Methods: In this
cross-sectional study, 722 volunteer from a total of 4000 prisoners in
Ankara Sincan Prison Campus between March and June 2013, were enrolled.
Results: Mean FBG level of whole study population was 101±28mg/dL. The
mean age and BMI of the prisoners with DM was significantly higher when
compared to the non-diabetics. We found the prevalence of DM as 3.8%.
Despite the presence of 252 (FBG≥100 mg/dL) prisoners with impaired FBG,
we could perform OGTT only in 12 prisoners. Three of them were diagnosed
with impaired glucose tolerance, and one was diagnosed with overt
diabetes. Conclusions: It may be estimated that there must be 4990
(3.8%) diabetic patients including 525 (0.4%) newly diagnosed ones
among in all Turkish prisons. In our study, the most important handicap
for determining DM prevalence in prisons is the tendency of the
prisoners to hide their disease.
