Authors: Gunawan Gunawan , Haris Abdul , Widodo Didik Setiyo , Suyati Linda , Septina Wilman
Published: February 2021

Methylene blue degradation carried out using cadmium sulfide (CdS) photoanode in photofuel cell (PFC) had been done. CdS synthesized by chemical bath deposition (CBD) on the FTO substrate was used as anode and platinum as a cathode in photoelectrochemical studies. Characterization of CdS thin film was done using EDX, XRD, SEM, Raman, UV-Vis absorption spectrophotometer as well as photocurrent test of the CdS thin film under illumination using potentiostat with the three-electrode system. The EDX result indicated the presence of CdS with an elemental composition of Cd rich. XRD showed the appearance of CdS crystals in cubic and hexagonal formations. SEM image of CdS gave results in the form of crystals of less than 1 mm. Raman spectrum showed the appearance of CdS peaks. The bandgap of CdS was estimated to be 2.38 eV, and the photocurrent test confirmed that the film had a property of n-type semiconductor. Application of CdS thin film as a photoanode in the PFC system using 100 mg/L methylene blue solution showed degradation up to 48% for 2.5 h using a 4 cm2 photoanode, and the maximum potential of 0.8 V was obtained with a photoanode area of 1 cm2.

This paper reports the effects of polypropylene-graft-maleic anhydride (PP-g-MA) and graphene nanoplatelet (GNP on tensile stress of various PLA/PP weight ratio. The PLA/PP blends prepared with the ratio 70/30, 80/20, and 90/10 with the addition of PP-g-MA (1 to 5 phr) and GNP (1 to 3 phr) by using an injection molding machine. The tensile stress (MPa) was analyzed based on 11 runs of full factorial design. The results showed that the tensile stress of PLA/PP blends gradually increased after the addition of PP-g-MA and GNP. There is a relationship between PP-g-MA and GNP which causes a positive impact on the mechanical properties of PLA/PP blends. The optimum tensile stress of 50.06 MPa achieved at the ratio of 90/10 blends with 5 phr of PP-g-MA and 3 phr of GNP.

Andrographolide, the major constituent from the terrestrial plant Andrographis paniculata is a much-studied bioactive ent-labdane diterpene lactone and has become an important medicinal intermediate. Its structure as determined by X-ray crystallography has been applied in molecular docking studies to explain biological activities. Nevertheless, recently there has been a number of conflicting reports concerning the stereochemistry at the C-14 and C-10 positions affecting the absolute configuration (AC) of the compound. Since a lack of information on the molecular flexibility of the molecule can lead to misleading conclusions on biological activity, a conformational analysis of the molecule in the solution state was necessary. The conformational analysis was performed by the Spartan14 package using the Merck Molecular Force Field (MMFF). The exciton chirality method in electronic circular dichroism spectroscopy (ECM-ECD) and vibrational circular dichroism (VCD) techniques were then jointly employed to re-establish the AC of andrographolide. Theoretical calculations were performed using TD-DFT methods by using the hybrid functionals B3LYP and CAM-B3LYP combined with 6-31G(d,p) basis set. Long-range exciton coupling of 2-naphthoyl chromophores at C-14 and C-19 led to the establishment of the AC to be 3R, 4R, 5S, 9R, 10R and 14S. Comparison between the theoretical VCD data of 14-S and 14-R stereoisomer confirmed a configuration of S at C-14 position instead of R.

Published: February 2021

A sustainable method was considered for the preparation of nanosilver and its allied nanoparticles. Nicotiana tabacum, an abused plant, has found an application as a bio-chemical instead of lethal chemical in the synthesis of nanoparticles. As part of green chemistry implementation, double distilled water was the solvent used for extraction. The phytochemicals present were analyzed using standard procedures. Nanoparticle synthesis was carried out at varying precursor concentrations, and the reaction was monitored with a UV-visible spectrophotometer. Another optical characterization was also achieved with photoluminescence. Other characterization involved: X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray (EDS), and Fourier transform infrared spectroscopy techniques (FTIR). A matched phase identification of nanosilver resembled a face-centered cubic of Ag with a mean size of 11.68 nm, and a lattice constant of 4.0862 Å. The Ag NPs displayed activity against clinical isolates of fungi, Gram-positive, and Gram-negative bacteria as the growth inhibition was significant at P < 0.05. Ag NPs obtained from the Nicotiana tabacum proved to be an antibacterial and antifungal candidate, unlike the Ag NPs derived using chemical and physical methods, which were harmful for this purpose. Both the Ag NPs and Ag-Ni NPs displayed optical activity, which qualifies them for application in visual materials.

Published: February 2021

Erlotinib, Afatinib, and WZ4002 are quinazoline derivative compounds and classified as first, second, and third-generation EGFR inhibitor. All inhibitors have been given directly to cancer patients for many years but find some resistance. These three compounds are candidates as the lead compound in designing a new inhibitor. This work aims to design a new potential quinazoline derivative as an EGFR inhibitor focused on the molecular docking result of the lead compound. The research method was started in building a pharmacophore model of the lead compound then used to design a new potential inhibitor by employing the AutoDock 4.2 program. Molecular dynamics simulation evaluates the interaction of all complexes using the Amber15 program. There are three new potential compounds (A1, B1, and C1) whose hydrogen bond interaction in the main catalytic area (Met769 residue). The Molecular Mechanics Generalized Born Surface Area (MM-GBSA) binding energy calculation shows that B1 and C1 compounds have lower binding energies than erlotinib as a positive control, which indicates that B1 and C1 are potential as EGFR inhibitor.
Конница тюрко-монгольских народов Великой степи в российской армии XVIII – начала XIX в. Часть 2

Published: February 2021

The article examines activities of Turko-Mongols to have inhabited the Great Steppe and adjacent territories in the military service of Russia throughout the 18th and early 19th centuries. The period witnessed the employment of ethnic military units of irregular cavalries Russian army recruited from the Mongolian-speaking Kalmyks and Buryats, Turkic-speaking Bashkirs, Teptyars, Mishar and Tatars. The work focuses on the largest ethnic military forces ― those of the Kalmyks and Bashkirs. Despite Russian forces were reorganized to from a regular army in the early 18th century, the latter still contained significant irregular components, including ones recruited from Turko-Mongols. Initially, the ethnic groups had served as independent military contingents with traditional structures, tactics, and weapons, but by the late 18th century all ethnic forces were clustered into Don Cossack-type regiments. The first part of the article deals with the features of military service of the Kalmyks and Bashkirs in their usual habitat ― in the Great Steppe. The second part of the article, which will be published in the next issue, analyzes the actions of the Turkic-Mongol cavalry in the three largest wars of Russia in the XVIII – early XIX centuries. (The Northern, Seven-Year War, the Patriotic War of 1812 and the Foreign Campaign of 1813–1814). Rational approaches and command of the ethnic units would yield good results ― both in Eurasian plains and European battlefields. The use of ethnic forces within the Russian army not only saved essential financial and physical resources for the defense of large territories and dramatically long frontiers but also facilitated further integration of their elites into the Empire’s community.

Introduction. During the period from 1898 till 1901 the German researcher Benjamin Bergman travelled to the Kalmyk steppes where he collected a lot of historical, literature and folklore materials. The result of this travel was the publication of the four-volume book “The Nomadic Roaming among Kalmyks in 1802–1803” by B. Bergman in 1804–1805 in Riga, this book is an important source of the information about the literature and culture of Kalmyks of the XIX century. Among the translations of the texts, this publication contains the translation of two songs of Geser from Kalmyk into German. This translation is the first translation of the Geser songs in Kalmykia. Goal. The goal of the article is to give to the fullest extent possible the bibliographic information about Benjamin Bergman as the researcher of the Kalmyk ethnos and highlight the nature of his translation of the two songs of Geser. Materials.Materials about Bergman family in German and four-volume book “The Nomadic Roaming among Kalmyks in 1802–1803” are used in the article. Results. In 1804–1805 on the results of the travel to the Kalmyk nomad roaming, Bergman published his famous four-volume work where he not only presented a lot of information about Kalmyks but also tried todispel several wrong perceptions about Kalmyks. His work is still relevant for the researchers of Kalmyk culture, history and literature. That is why it was republishedin Europe in 1969.

The history of the appearance of the oirat translation of the “Golden Light Sutra” and its significance in the religious tradition of the oirats is one of the most interesting problems of modern mongolian studies. This paper examines the woodcut text of the oirat translation of one of the most famous texts of mahayana buddhism, “Golden Light Sutra”. Despite the huge number of manuscripts of this sutra on the oirat “clear letter”, only two woodcuts of this sutra are known to have survived to this day. One copy of the woodcut it was kept kept in the manuscript collection of the Institute of Language and Literature of the Academy of Sciences of Mongolia. Another copy of the woodcut “ Golden Light Sutra “, known as the Kalmyk woodcut, is kept in the personal archive of Uwelzeng Genge in the territory of the Xinjiang Uygur Autonomous Region of the People’s Republic of China.

One of the interesting issues of the contemporary Mongolian Literature Studies is the history of the introduction of different literary terms and concepts. Some terms over the time have obtained a new meaning different from the initial one. One of the terms that has undergone this evolution is the term nӓӓrgll (poem). This term denoting a ‘poem’ first appeared in Mongolia in the work of the famous Mongolian philologist, academician M. Gaadamba “Essay on the Theory of Literature” and in the translation of the famous Soviet researcher G. L. Abramovich “Introduction into the Literature Studies”. In 1950, this term was actively used by critics and historians of the contemporary Mongolian literature of China. Initially, the term nӓӓrgll denoted a “poetic story” (shülglsn tüük (shüleglesen tuuzh)) which had a borderline position between a “poetic novel” (shülglsn roman) and a “poetic narrative” (shülglsn түүк (hüleglesen tuuzh)). However, the deeper analysis of the critical and Literary Studies works of the given period showed that this term was used for different types of literary works.

The article gives the analysis of the memorialization process of the residents of the Kalmyk ASSR — the participants of the Great Patriotic War 1941–1945 in the memorial books of the regions and villages of Kalmykia. Nowadays, in the regional historiography there are memorial books of the four regions (Priyutnenskiy, Tselinniy, Yashkulskiy and Chernozemelskiy) and the three village municipal units (Chilgir, Erdnievskiy and Artezian). These publications have different annotated and non-annotated lists of the participants of the 1941–1945 war from the respective regions and villages. These lists have varying degrees of informational content, but the lists that have been methodically and conscientiously complied for a long time cover most of the persons they were looking for. Nevertheless, the task of complete memorialization of our fellow countrymen who participated in the Great Patriotic War of 1941–1945 remains unresolved to this day.

The article introduces the Oirat handwritten text “Coqtu Zandan” (‘Shining Sandalwood’) from the collections of the Russian National Library. The text “Coqtu Zandan” is a translation of the prayer of repentance common in the Tibetan-Mongolian buddhist tradition, which is read out during the ritual of restoring the sojong vows. This prayer is mentioned under no. 23 (as “bodhi sadv-yin unal namančilaxui kemekü sudur”) in the list of translations of Zaya Pandita Namkhaijamts. The Tibetan original of this work, researchers call the text “Ltung Bshags” or one of the versions of the “Sutra of the Three Piles” (tib. phung po gsum pa’i mdo), included in the collection of the terma-works “Rinchen Terdzo”. The Sanskrit text of the Sutra “Aryatriskandha sūtram” has also reached our time, a digital copy of which is available on the website of the Digital Sanskrit Buddhist Canon Input Project. The publication of parallel Sanskrit and Tibetan Sutra texts within the framework of this article is also very relevant.

O artigo faz uma abordagem teológico-pastoral da missão ad gentes antes, durante e depois do Concílio Vaticano II, a partir de estudos bibliográficos de autores que se debruçaram sobre o tema. O texto tem dois momentos. O primeiro apresenta a situação da missão antes e no contexto do Vaticano II. O segundo enfoca a missão no contexto da implementação da renovação conciliar. O estudo mostra que o conceito de missão foi mal entendido no período da cristandade, levando a um desvio da atividade missionária na igreja da época. O Concílio, em sua volta às fontes, corrigiu equívocos e colocou as bases de uma atualizada teologia da missão, em sintonia com o espírito da proposta evangélica.
A DIMENSÃO PRÁTICA NO PENSAMENTO DE MELANCHTHON
Authors: Gross Eduardo
Published: February 2021

O presente estudo visa mostrar como a pesquisa recente sobre Melanchthon tem ressaltado a dimensão prática em seu pensamento para além da já antes amplamente reconhecida preocupação com a ética, que por isso não será discutida aqui diretamente. Apresentam-se resultados de pesquisas significativas sobre seu viés prático humanista enquanto princípio para a crítica da Escolástica, sobre o caráter existencial de sua perspectiva reformatória luterana e sobre a dimensão pedagógica de sua reflexão, entendida não no sentido de propostas educacionais concretas, mas como princípio interno que guia a reflexão em si. Para clarificação do conceito de prática parte-se da referência à distinção aristotélica entre práxis e poiesis feita por Vítor Westhelle.

a specialized function, and is known to transfer antifungal microbes to
eggshells during oviposition. We hypothesize that the cloacal microbiome
is distinct from other parts of the digestive and reproductive systems.
Here, we compare the microbiome of tissue samples from the cloaca, lower
intestine, upper intestine, and oviduct. We further assessed whether
common methods of microbial sampling – cloacal swabs and feces –
provide accurate representations of these tissues, and whether feces
might “seed” the cloacal microbiome. We found that the upper intestine
and oviduct had unique microbial communities, while the lower intestine
and cloaca had similar communities with lower diversity indicative of
regional specialization. The cloacal community, in particular, showed
extreme specialization averaging 99% Proteobacteria (Phylum) and 83%
Enterobacteriacaea (Family). Cloacal swabs recovered communities similar
to that of lower intestine and cloacal tissues, but fecal samples had
much higher diversity and a distinct composition (62% Firmicutes and
39% Lachnospiraceae) relative to all gut regions. This result serves as
a caution against the frequent assumption that fecal samples provide an
accurate representation of the gut. Finally, we found that defecation
did not alter the cloacal microbiome, suggesting that community is
robust to perturbations from transient microbiota.
Climate and density-dependent population dynamics: Lessons from a simple high-Arctic ecosystem

The strikingly diverse population dynamics of herbivorous small mammals,
ranging from high-amplitude, multi-annual cycles to relatively stable
dynamics, have puzzled ecologists for a century. Theory predicts that
this diversity is shaped by density-dependent food web interactions and
stochastic weather events. Recent disrupted cycles through amplitude
dampening have been attributed to climate change. However, empirical
testing has been hampered by the complexity of the food webs in which
these herbivores normally are found. Here we analyze population dynamics
of a grazing vole species in a uniquely simple high-Arctic food web
without top-down regulation. In accordance with theory, the population
dynamics was mostly ruled by overcompensatory density-dependence in
winter that without environmental stochasticity would have yielded
seasonality driven high-amplitude 2-year cycles. In this simple food
web, rain-on-snow events disrupted cyclicity, but not through amplitude
dampening. Our case study highlights how food web structure may modify
the impact of climate change on population dynamics.
Contrasting effects of ecological and evolutionary processes on range expansions and shifts
Authors: Weiss-Lehman Christopher , Shaw Allison
Published: February 2021

Research has conclusively demonstrated the potential for dispersal
evolution in range expansions and shifts through a process termed
spatial sorting. However, the degree of dispersal evolution observed has
varied substantially among organisms. Further, it is unknown how the
factors influencing dispersal evolution might impact other ecological
processes at play. We use an individual-based model to investigate the
effects of the underlying genetics of dispersal and mode of reproduction
in range expansions and shifts. Spatial sorting behaves similarly to
natural selection in that dispersal evolution increases with sexual
selection and loci number. Contrary to our predictions, however,
increased dispersal does not always improve a population’s ability to
track changing conditions. The mate finding Allee effect inherent to
sexual reproduction increases extinction risk during range shifts,
counteracting the beneficial effect of increased dispersal evolution.
Our results demonstrate the importance of considering both ecological
and evolutionary processes for understanding range expansions and
shifts.

Covid-19 is a viral multisystemic disease that caused a worldwide
pandemic in 2020 (1). Due to the rapidly increasing number of cases, all
medical doctors in many countries of the world, regardless of their
specialties, took part in the treatment of COVID-19 patients.It has been
reported that a significant number of COVID ‐ 19 patients appear to have
loss of smell (anosmia) and taste (dysgesuia). We observed that the loss
of taste and smell improved in 2-5 days with doxycycline treatment in 4
covid-19 patients .Doxycycline, whose effectiveness against Covid-19 has
been shown by various studies, can be a considerable therapeutic option,
regarding that it may also improve loss of taste and smell that are very
distressing symptoms. We contribute to this recommendation with four
cases we present in this article.

Authors: Yurt Nur Simsek , Ocak Metin , Yurt Yusuf Can
Published: February 2021

Introduction: As COVID-19 disease has rapidly spread across the world,
its impact has grown with increasing number of cases and mortality rate
in Turkey. Aim: The aim of this study is to examine epidemiologic and
clinical features of the patients that admitted to the hospital with the
pre-diagnosis of coronavirus disease-2019 (COVID-19) in Turkey. Method:
In this retrospective study, epidemiologic and clinical features,
laboratory findings, radiologic features, therapeutic approaches and
survival conditions of the patients with the pre-diagnosis of COVID-19
from March 11th to June 30th, 2020. The all data of the cases were
compared in 4 groups: 1st group for the confirmed cases reverse
transcriptase polymerase chain reaction (RT-PCR) +, chest computed
tomography (CT) +, 2nd group for the clinically diagnosed cases (RT-PCR-
CT +), 3rd group for the mild and asymptomatic cases (RT-PCR + CT-), 4th
group for the suspected cases (RT-PCR - CT -). Post-hoc analysis was
performed to evaluate the differences among the groups. Results: In
total, 3334 patients with the pre-diagnosis of COVID-19 admitted to the
emergency department. Based on the post-hoc analyses, significant
differences were found among the four groups in terms of their test
results of leucocytes, hemoglobin, platelets, neutrophils, urea and
C-reactive protein (CRP) (p<0.001). Furthermore, the factors
of age groups, hospitalization, intensive care follow-up and mortality
rate of the four groups showed a significant difference among the groups
(p=0.001). Conclusion: Mean of leucocytes, neutrophile and platelet
values of the patients with tested positive for the RT-PCR was found
lower compared to the ones with tested negative for the RT-PCR. Mean of
CRP values was found higher in patients with lung involvement compared
to other patient groups.

Aims Delay and false positivity in PCR test results have necessitated
accurate chest CT reporting for management of patients with COVID-19
suspected symptoms. Pandemic related workload and level of experience on
covid-dedicated chest CT scans might have effected diagnostic
performance of on-call radiologists. The aim of this study is to reveal
the interpretation errors in chest-CT reports of COVID-19 suspected
patients admitted to the ER. Methods COVID-19 dedicated chest-CT scans
which were performed between March and June 2020 were re-evaluated and
compared with the former reports of these scans and PCR test results. CT
scan results were classified into four groups. Parenchymal involvement
ratios, radiology departments’ workload, COVID-19 related educational
activities have examined. Results Out of 5721 Chest-CT scans, 783 CTs
belonging to 664 patients (340 female, 324 male) were included to this
study. RT-PCR test was positive in 398; negative in 385 cases. PCR
positivity was found to be highest in “normal” and “typical for
covid” groups whereas lowest in “atypical for covid” and “not
covid” groups. 5-25% parenchymal involvement ratio was found in 84.2%
of the cases. Regarding number of chest CT scans performed,
radiologists’ workload have found to be increased six-folds compared to
the same months of the former year. With the re-evaluation, a total of
145 IEs (18.5%) have been found. IEs were mostly precipitated in the
first two months (88.3%) and mostly in “not covid” class (60%)
regardless of PCR positivity. COVID-19 and radiology entitled
educational activities along with the ER admission rates within the
first two months of pandemic have seem to be related with the decline of
IEs within time. Conclusion COVID-19 pandemic made a great impact on
radiology departments with an inevitable burden of daily chest-CT
reporting. This workload and concomitant factors have possible effects
on diagnostic challenges in COVID-19 pneumonia.

Background: Covid-19 is an extremely contagious illness caused by the
severe acute respiratory syndrome (SARS-CoV-2) virus. Although this
disease primarily involves pulmonary tissue, rapidly advancing research
has established cardiac involvement in Covid-19 patients. Objective:
This systematic review article aimed to compile and illustrate clinical
characteristics, diagnostic findings, management, and outcomes
manifesting in myocarditis linked with Covid-19. Methods: A literature
search was accomplished for published eligible articles with
MEDLINE/PubMed and Embase databases. All eligible case reports and case
series were included from around the world without any language
restrictions. For this review, inclusion criteria were
laboratory-confirmed SARS-CoV-2 infection cases reporting a diagnosis of
acute myocarditis. Results: Data from 41 studies describing myocarditis
in 42 Covid-19 patients was obtained. The median age of these patients
was 43.4 years, with 71.4% of them being male. Fever was the most
prevalent presenting symptoms seen in 57% of patients. Hypertension was
the most pervasive comorbidity accompanying these patients. Cardiac
biomarkers troponin and Brain natriuretic peptide (BNP) were raised in
almost 90% and 87% of patients, respectively. Electrocardiogram
findings were Non-specific and included ST-segment and T-wave changes.
The most prevalent histopathological feature appreciated was diffuse
lymphocytic inflammatory infiltrates. Antivirals and corticosteroids
were the most frequently used medications. About 38% of patients also
needed vasopressor assistance. Out of 42 patients, 67% recovered, and
eight died. Conclusion: Due to the risk of a sudden worsening of
patients conditions and myocarditis association with considerable
mortality and morbidity, a knowledge of this cardiac complication of
Covid-19 disease is crucial for healthcare professionals.

Introduction Detail 3D mapping have been useful for effective
radiofrequency catheter ablation. Rhythmia system can create the
atrio-ventricular dual chamber mapping, which reveals the atrial and
ventricular potentials all at once in the same map. The aim of this
study was to investigate the utility of Rhythmia system for catheter
ablation of accessory pathways (AP). Methods From July 2015 to August
2020, 111 patients underwent ablation of APs. The dual chamber mappings
were created in 50 patients [median age 15 (10-54), 32
male(64.0%)], while 61 patients underwent the radiofrequency (RF)
ablations with conventional single chamber 3D mappings. The background
characteristics and procedure details were compared between the dual
chamber mapping group and conventional single chamber mapping group.
Results The number of RF application [1 (1-3) vs 3 (1-6), p=0.0023],
RF time [9.2 (2.0-95.7) vs 95.6 (4.1-248.7), p=0.0023], RF energy
[248.4 (58.7-3328.2) vs 2867.6 (134.2-7728.4), p=0.0115] were
significantly lower in dual chamber group. Fluoroscopy time [19.9
(14.2-26.1) vs 26.5 (17.7-43.4), p=0.0025], and fluoroscopy dose
[52.5 (31.3-146.0) vs 119.0 (43.7-213.5), p=0.0249] were also
significantly lower than in single chamber mapping group. Conclusion The
dual chamber mappings were useful for effective ablation with reducing
the radiation exposure.
