Published: March 2022

Objectives

Liver illnesses are a major public health issue all over the world. Medicinal plants constituents a viable alternative for the development of phytopharmaceuticals with hepatoprotective activity in order to solve some of these health-related problems. The present study is focused on the phytochemical and biological investigation on Indian traditional medicinal plant extracts, for their cytotoxic and hepatoprotective activity. The isolated compounds showed the presence of phenolic constituents which lead to cytotoxicity and hepatoprotective activity of medicinal plant. Cancer causes about 13% of all human deaths in 2007 (7.6 million) (American Cancer Society and WHO December 2006–07). The American Cancer Society estimates that 12,990 new cases of cervical cancer will be diagnosed in the United States year 2016. Cancer-related deaths are expected to increase, with an estimated 11.4 million deaths in 2030.

Methods

The ethanolic extracts of Centella asiatica, Myristica fragrans, Trichosanthes palmata, Woodfordia fruticosa, Curculigo orchioides were evaluated against HEP-G2 cell lines for hepatoprotective activity and Curculigo orchioides was further promoted for the isolation of secondary metabolites based on inhibitory concentration.

Results

The ethanolic extracts of C. asiatica, M. fragrans, T. palmata, W. fruticosa, Curculigo orchioides shown significant cytotoxic activity (IC50≤100 μg/mL). The plant extracts also shown significant hepatoprotective activity in a dose dependent manner when tested against HEP-G2 cell lines and cytotoxicity studies against HeLa and HEP-G2 cells.

Conclusions

The extract of Curculigo orchiodes rhizome showed significant cytotoxicity results. Hence the Curculigo orchiodes rhizome was selected for further phytochemical studies to isolate active compounds and their Characterization by GCMS.

Towards a Phenomenology of Kenosis: Thinking after the Theological Turn
Authors: Cassidy-Deketelaere Nikolaas
Published: March 2022

What could it mean to think “after the theological turn”? This article proposes one possible answer by reframing the theological turn in light of the way in which Paul’s kenosis serves as a metaphor for deconstruction in a variety of continental philosophers who are all nevertheless hostile to overt theologising. Tracking this notion through the history of theology and philosophy, the article argues that it has been philosophically appropriated so as to indicate the point within the Christian theological complex that constitutes its fatal agent by setting in motion Christianity’s own self-deconstruction or de-theologisation. This dynamic, which implies that every engagement with theology ultimately carries itself outside of theology proper, will then allow the article to reconceive the gesture operated by phenomenology’s theological turn: in their right turn towards theology, the philosopher must be careful not to simply remain stuck there, for it only serves their investigation insofar as this engagement is precisely what allows them to turn away from “the theological,” or for phenomenology de-theologise itself. By drawing out the kenotic motif in contemporary continental philosophy and connecting it to phenomenology’s theological turn, the article thus argues that what is needed now is a deconstruction of the theological turn. This can be accomplished by way of what the article proposes to call a “phenomenology of kenosis”: namely, a phenomenology that starts from theology (Paul’s notion of kenosis), precisely so as to move beyond it (to de-theologise itself).
Global Control of Tuberculosis: Current Status and Future Prospects
Authors: Huang Fei , Zhao Yanlin
Published: March 2022

Tuberculosis is a zoonotic disease that is caused by mycobacterium tuberculosis complex and can infect humans, livestock, and wildlife. It spreads primarily through the respiratory tract and was the leading cause of death due to a single infectious disease before the COVID-19 pandemic. TB is a global public health emergency that has reemerged over the past few decades. Substantial efforts are needed to achieve the goals of the End TB Strategy. The World Health Organization has estimated that approximately 9.9 million people worldwide contracted TB in 2020 and that approximately 140,000 of the 10 million new cases of active TB in 2019 were zoonotic TB. During the COVID-19 pandemic, the number of new TB diagnoses and reports decreased sharply, from 7.1 million in 2019 to 5.8 million in 2020, returning to 2012 levels far below the approximately 10 million TB cases in 2020. Simultaneously, the global decrease in the absolute number of TB deaths until 2019 was followed by an increase in 2020 in four of the six WHO regions and most of the 30 high-TB-burden countries. Therefore, extensive immediate actions worldwide are required to restore the health system, and innovations are needed to accelerate progress toward a tuberculosis-free world.

Authors: Voronina Elena S. , Bucharskaya Alla B. , Palatova Tatiana V. , Fomkin Roman N. , Navolokin Nikita A. , Maslyakova Galina N.
Published: March 2022

Objective — To compare the expression of the LC3B autophagy marker before and after treatment with high-intensity focused ultrasound therapy (HIFU) and combined therapies: androgenic deprivation AD + HIFU, AD + radiation therapy in patients with and without recurrent prostate adenocarcinoma. Material and Methods — The objects of our study were biopsy specimens of prostates obtained from 70 patients with prostate adenocarcinoma before and after treatment. The first group consisted of patients without signs of relapse after treatment, as evidenced by a normal blood PSA level, the results of ultrasound procedure and biopsy. The second group included patients who had a recurrence of adenocarcinoma after treatment. Patients received the following cancer treatments: ultrasound ablation (HIFU), combination therapy: androgenic deprivation AD + HIFU, AD + radiation therapy. An immunohistochemical staining in two groups was performed with an anti-LC3B antibody. Results — In the group of patients without relapse, the expression of the autophagy marker sharply decreased in the tumor tissue after treatment, but it increased in the stroma of muscle connective tissue and the vascular wall. In the group of patients with relapse, the expression of anti-LC3B antibody significantly increased in tumor cells, in stroma of muscle connective tissue, and in vascular wall after treatment. In both groups, the magnitude of the autophagy marker expression did not depend on the treatment method. Conclusion — The autophagy is one of the factors contributing to the survival of prostate adenocarcinoma cells after treatment; the increase in autophagic protein expression after treatment in patients with prostate adenocarcinoma can be used to assess the risk of relapse.

Authors: Klimenko Elizaveta S. , Igumnov Ilya A. , Markova Daria P. , Belkova Natalia L. , Suturina Larisa V.
Published: March 2022

Human oral cavity is a diverse habitat, consisting of many locations with its microbiotas. It was proven that bacteria detected in saliva could be the indicators of disease and be useful for diagnosis, monitoring, and overall assessment of the patient health. As pilot research of microbial communities associated with polycystic ovary syndrome (PCOS), biomaterials were collected from two patients (saliva, the contents of gingival pockets) for sequencing the amplicon libraries V4-V6 of variable regions of the 16S rRNA gene. Our study aimed at comparing the taxonomic and functional profiles of different locations in the oral cavity. Material and Methods — DNA samples were sequenced using Illumina MiSeq; the qiime2-2020.2 and PICRUSt2 v2.4.1 software packages were used to process the sequencing results of the amplicon libraries. Results — We demonstrated that the salivary microbiome had a greater taxonomic diversity, compared with the microbiome of the periodontal pockets. Regarding the ratios of different taxonomic group abundances, the species ratio in the saliva community significantly differed from the ratio in periodontal pockets. The microbiota of the oral cavity was classified as a producing community, since many different biosynthetic pathways were predicted. Similar functional features were identified for microbial communities in other locations. Conclusions — Different locations in the biotope of the oral cavity have varying species richness of their communities and specific taxonomic composition. However, the microbiotas of different microniches perform similar metabolic functions. This finding allows considering the analysis of saliva microbiota sufficiently representative tool for characterization of the entire oral microbiome.
Locally invasive classical papillary thyroid carcinoma with TSH receptor I568T mutation: case report
Authors: Nguyen Jay , Joseph Dennis
Published: March 2022

Autonomous thyroid adenomas are caused by activating mutations in the genes encoding the thyroid-stimulating hormone receptor (TSHR) or mutations in the Gas subunit of the TSHR. Nodules with suspicious sonographic features should be submitted to fine-needle aspiration. Additional molecular testing may be performed to characterize the thyroid nodule’s malignant potential further. We present a patient who underwent whole-transcriptome RNA-sequencing that indicated a TSHR I568T mutation after an ultrasound showed suspicious sonographic features and fine-needle aspiration was ‘suspicious for malignancy’. The patient underwent thyroid resection and was found to have a locally invasive classical papillary thyroid carcinoma. Most reports of TSHR I568T mutation have been seen in patients with benign thyroid conditions. While there is insufficient data to suggest that the TSHR I568T mutation causes aggressive thyroid malignancy, we believe clinicians who identify the presence of this mutation on genome sequencing should be cautious about the possibility of locally invasive thyroid malignancy, especially when associated with Bethesda V cytopathology.

Learning points

Germline and somatic activating mutations in the genes coding for the thyroid-stimulating hormone receptor (TSHR) have been frequently reported in familial and sporadic autonomous thyroid adenomas and non-autoimmune hyperthyroidism.

Most reports of TSHR I568T mutation have been detected in patients with benign thyroid conditions.

We present a patient who underwent whole-transcriptome RNA-sequencing that indicated a TSHR I568T mutation and subsequently underwent thyroid resection and was found to have a locally invasive classical papillary thyroid carcinoma.

Clinicians who identify the presence of TSHR I568T mutation on genome sequencing should be cautious about the possibility of locally invasive thyroid malignancy, especially when associated with Bethesda V cytopathology.

Published: March 2022

Obstetric violence is an often overlooked obstacle to quality of health care service during childbearing and it has not received much attention in India. In this paper, our aim is to study the experiences and impacts of Obstetric violence on Indian women during the period of childbearing. A total of 256 women were interviewed in two districts (Sambalpur and Bargarh) of Odisha, India in between the age of 18 and 35 years in their latest childbirth within the last 5 years. We found that 83 women (32.4 percent) have experienced obstetric violence (Non-dignified care and physical abuses) and the prevalence is more among the women of lower caste and lower socio economic groups. Results also indicate that obstetric violence has long-lasting, chronic and fatal health consequences and many victims also reported serious deterioration in spousal and family relationship. It is a human rights problem that must be prevented and eradicated.
Development Aspects of Archaeological Sites in Latvia
Authors: Kairišs Andris , Oļevska Irina
Published: March 2022

Archaeological sites as part of cultural heritage satisfy a broad range of interests of different stakeholders. Along with satisfying cultural, social, scientific, etc., interests, their role is no less important in strategic socio-economic development.Unlocking asocio-economic potential of archaeological sites requires clear vision of how to conserve and protect each particular site, how and by what means to maintain and manage the object as well as what to do with it next. It is widely acknowledged that archaeological sites, in particular those having the status of archaeological monuments, play a socially important role, but their maintenance and development often require significant investment. While the laws make owners of archaeological sites, both private and public, solely responsible for conservation, restoration and maintenance of cultural monuments in their property, there should be appropriate mechanisms that mitigate the financial and legal burden and support owners along the way.Based on the review of legal regulation, scientific literature, information of the authorities and mass media, multiple expert interviews, consultations with professional archaeologists, and using an integrated socio-economic and legal approach to the researched issue, the article provides theoretical and practical insight into the actualities of archaeological heritage development potential in Latvia (making international comparisons) and possible solutions thereto.

Authors: Buržinskas Žygimantas
Published: March 2022

This study presents data reflecting the urban development of Merkinė in the 16th–18th centuries. The old names of the city streets and the development of the street structure are analyzed. After the analysis of historical sources, the approximate location of the lost masonry and other town buildings is presented, as well as the data of residential and public town buildings and the manor house. In the 16th–18th centuries, wooden buildings dominated in the town, but sources testify that, especially before the mid-17th century war, brick residential buildings were also built in the main town streets. Along with the town hall, the parish church dominated in the structure of the town, as well as the churches and monasteries of the Jesuit residence and the Dominican convent, and on the top of the town a wooden St. Peter’s and St. Paul’s Church stood, which was to be prominently seen in the town’s skyline.
The Research of Clay Tobacco Pipes and Its Methodological Aspects
Authors: Žvirblys Atas
Published: March 2022

Clay pipes are quite a common finding in the study of urban cultural strata, a dozen thousand fragments of them are counted in the collections of Lithuania museums. Nevertheless, the terminology of these of tobacco pipes is not yet quite settled in Lithuania, and archaeologists who investigate urban areas do not even have a methodical material published in Lithuanian. The article aims to distinguish and define the methodological aspects of the analysis of clay tobacco pipes dated from the first half of 17th century to 19th century, which would be suitable for the Lithuanian context. At the beginning of this article, the history of clay tobacco pipes research is analyzed in a methodological aspect, the links to the whole development of archaeology science are presented, and the current tendencies in the tobacco pipes researches are described. The other chapters focus on the matters of clay pipes terminology, methods of analysis, and dating. Considering the locally produced and imported pipes found in Lithuania, methodical matters of recording and describing these findings are analyzed, as well as possible interpretations of the collected data.

Published: March 2022

The average gamma-ray spectrum of 114Cd after thermal neutron capture in 113Cd was evaluated in units of mb/MeV. Two approaches are considered for estimation of the average gamma-ray spectrum with normalization of the experimental data: mean spectra for all gamma-energies were found by averaging frequency polygon for experimental data histogram, and mean spectra were estimated as the combination of theoretical values at low gamma-ray energies and averaging experimental data in high-energy range. The experimental spectra were evaluated from the gamma-intensities presented by Mheemeed et al. [A. Mheemeed et al. Nucl. Phys. A 412 (1984) 113] and Belgya et al. [T. Belgya et al. EPJ Web of Conf. 146 (2017) 05009]. They were normalized to the average theoretical spectrum which was calculated using EMPIRE and TALYS codes. The procedure of normalization of the high-energy part of the spectrum was described. Estimated gamma-spectra for 113Cd(n, {xγ}) reaction induced by thermal neutrons were presented.

Impact of Magnetic Field on Magnetic States in Kagome Magnets
Authors: Tran Thanh Mai , Tran Minh Tien
Published: March 2022

Impact of magnetic field on the magnetic states in kagome magnets is studied. The magnetic field is patterned in such a way that it can generally maintain the most prominent magnetic states in kagome magnets, such as the out-of-plane ferromagnetism and the in-plane antiferromagnetism. The tight-binding model with the spin-orbit coupling and the magnetic field on the kagome lattice is exactly solved. In both the out-of-plane ferromagnetic and the in-plane antiferromagnetic states the magnetic field opens a gap at half filling. In the out-of-plane ferromagnetic state both the half topological state, where only one spin component is topologically nontrivial, and the quantum spin anomalous Hall effect, where both spin components are topologically nontrivial, can be observed. The in-plane antiferromagnetic state may be insulating, but it is topologically trivial. The quantum anomalous Hall effect may also be observed in canted \(\sqrt{3} \times \sqrt{3}\) antiferromagnetic state.

Authors: Pham Cong Ly , Ngoc Tri Huynh Nguyen , Pham Huong Huyen Nguyen , Nguyen Khanh Son
Published: March 2022

Soil bio-cementing is a promising technique for ground stabilization and/or production of unfired clay brick using bacteria. This study reported new findings using Sporosarcina pasteurii, a ureolytic baterium and a mixture of perfect particle package of expanded glass granules as a soil model. For bacteria growth, the nutrition solution was carefully prepared in the laboratory condition from different indigents such as casein, soymeal, NaCl, urea and CaCl2. Three mixtures containing large, medium and small granules were analyzed with regards to its compactness. As constated, round shape and high water absorption of glass granules helps us providing an ideal condition for biomineralization process. Precipitated products responsible for bonding glass beads were characterized with different techniques such as XRD, SEM. Calcium carbonate was regconized as the main generated product due to bacteria metabolism. Results of microscopic observation revealed the various position of bonding bridges between glass granules that placed side by side on petri dish and in the cylindrical mold. Obviously, the effect of curing time on the result of bonding materials was observed as a decisive factor for 7 and 21 days specimens. The model of soil particle packing from glass granules help us more easily to investigate the cementing ability of bacteria. From this study, we could consider future studies of soil biocementing with different strains of bacteria.
Cimento de baixo impacto ambiental a partir dos resíduos cauliníticos da Amazônia
Authors: Arruda Junior Euler Santos , Barata Márcio Santos
Published: March 2022

RESUMO O emprego de adições minerais como substituição parcial do clínquer no cimento Portland tem sido uma das principais estratégias para redução da emissão de CO2 por parte da indústria mundial do cimento. Contudo, a disponibilidade de escórias de alto forno e cinza volante não supre a demanda. Na Amazônia, as indústrias de beneficiamento de caulim como cobertura para papel já depositaram cerca de 70 milhões de toneladas de resíduos constituídos essencialmente por caulinita extremamente fina. Uma alternativa para a região seria o emprego do cimento Portland com adições minerais de calcário e argila calcinada para a produção de um cimento de baixa emissão de CO2, o limestone calcined clay cement (LC3). O objetivo deste trabalho foi avaliar as propriedades desses cimentos a partir de elevadas incorporações de calcário e do metacaulim proveniente do resíduo calcinado do processamento da mina, o caulim flint. Os percentuais avaliados de substituição do clínquer Portland pelas adições minerais foram 45% e 60%. As variáveis investigadas foram a massa específica, a área superficial especifica Blaine, a água de consistência, os tempos de pega e a resistência à compressão. Os cimentos de metacaulim e calcário apresentaram maior demanda de água e menores de tempos de pega em razão da elevada finura da caulinita. Entretanto, os ganhos de resistência à compressão foram significativos em comparação aos obtidos com os cimentos Portland composto e comum, demonstrando a alta eficiência deste ligante. Os resultados são promissores, mas requerem estudos mais aprofundados, principalmente no que tange à durabilidade e à estabilidade dimensional de concretos e argamassas produzidos a partir destes cimentos.

Matched-accent processing: Bulgarian-English bilinguals do not have a processing advantage with Bulgarian-accented English over native English speech
Authors: Dokovova Marie , Scobbie James M. , Lickley Robin
Published: March 2022

The Interlanguage Speech Intelligibility Benefit (ISIB) hypothesis for Talkers suggests that there is a potential benefit when listening to one’s second language when it is produced in the accent of one’s first language (matched-accent processing). This study explores ISIB, considering listener proficiency. According to second language learning theories, the listener’s second language proficiency determines the extent to which they rely on their first language phonetics, hence the magnitude of ISIB may be affected by listener proficiency. The accuracy and reaction times of Bulgarian-English bilinguals living in the UK were recorded in a lexical decision task. The English stimuli were produced by native English speakers and Bulgarian-English bilinguals. Listeners responded more slowly and less accurately to the matched-accent stimuli than the native English stimuli. In addition, they adapted their reaction times faster to new speakers with a native English accent compared to a Bulgarian accent. However, the listeners with the lowest English proficiency had no advantage in reaction times and accuracy for either accent. The results offer mixed support for ISIB for Talkers, and are consistent with second language learning theories according to which listeners rely less on their native language phonology when their proficiency in the second language has increased.
Learning from Psychiatry? Gottfried Benn, Alfred Döblin, and the Limits of ‘Narrative Medicine’
Authors: Craig Robert
Published: March 2022

In critical dialogue with contemporary ‘narrative medicine’, a concept popularised by Rita Charon, this article re-examines representations of mental illness in the short prose of the German Expressionist writers and doctors Alfred Döblin (1878–1957) and Gottfried Benn (1886–1956). Taking as my focus Döblin’s story, ‘The Murder of a Buttercup’ [‘Die Ermordung einer Butterblume’] (1912), and Benn’s cycle of ‘Rönne novellas’ (1916), I argue that their protagonists embody a form of ‘narrative modality’: a futile attempt to fashion entangled and chaotic mind-body relationships into self-controlled and socially sanctioned subjectivities. Michael Fischer’s hallucinations have often been read as the symptom of nature’s mythic revenge on the alienated modern subject, and they have also been associated with various specific psychopathologies. By considering the story’s resonances with contemporary biopolitical discourses, Döblin’s own psychiatric research, and Oliver Sacks’ neurological case studies, I read our inability to ‘pin Fischer down’ both as the mirror image of his inability to control a wayward body and mind, and as the marker of his broken yet irreducible humanness. Benn’s autobiographically inflected ‘novellas'—as he termed his experimental pieces—trace the repeated collapse of Dr Werff Rönne’s attempts to re-establish a stable sense of self. This collapse sounds the death knell for those endeavours and, at the same time, it opens radically new possibilities for both thinking and being. My article shows how these authors probe the very limits of literary narrative in its capacity for doing justice to the strange and singular lived experiences of mental illness.Featured image: A Detail from Egon Schiele, Der Tod und das Mädchen [Death and the Maiden], 1915.

Language Learning through Interaction: Issues in Second Language Acquisition
Authors: Tshering Karma
Published: March 2022

This study was done to investigate how children acquire and learn languages as they grow mentally and physically. The theories of second language acquisition state that the dominating factor affecting second language acquisition are motivation, cognitive style, sociocultural, and other linguistic factors. The Behaviorist Theory of Language acquisition states that children learn language through motivation while the Cognitivist theory claims that language develops through the concepts of memory and time. Likewise, the Innatists claim that children are born with an innate quality of universal grammar to acquire language automatically as they grow. The socioculturalists claim that language acquisition and learning occurs through social interaction without having required to force them to learn a language. The paper found that “input” factor has improved and progressed the linguistic competence of the learners which is seen in Bhutanese children being able to understand more than two languages like Nepali and Hindi. Most of the Bhutanese children understand the above two languages without

having attended any formal classes but all learned through the “Input” factors of exposure to television and contacts. The findings of this paper indicated that conversational interaction in second language learning had enhanced the language development of children at a young age.

Authors: Pokhrel Sumitra
Published: March 2022

This study attempts to present reflective teaching practice as a tool for educators for continued professional development. Reflective teaching allows to adopt and develop classroom practices making educator a lifelong learner. Enhancing the quality of teacher to improve the quality of education is one of the strategies of education system of many countries ,including Bhutan. Education system of Bhutan is built on the unique Bhutanese values of tha dam- tshig ley gjudrey and philosophies of child centeredness, inclusivity and lifelong learning. Upholding these values, educator must engage in introspecting their teaching practices, analyzing how something was taught and ways to improve/modify practices to enhance academic performance of the learner. The purpose of this paper is to promote reflective thinking and reflective teaching practice among educators and adopt better technique of teaching methods to suit the evolving learning need of the students. It is also to encourage continuous enhancement of teaching profession. It incorporates the case study carried out for a considerable group of students in the class levels where the researcher was teaching. The case study throws some light on how different

components of classroom teaching is implemented and identifies adjustments required.

Authors: Dorji Tshering , Nima Pelden
Published: March 2022

The present study developed and evaluated the content validity of a survey questionnaire titled, “Instrument to Assess Teachers’ Practice of

Differentiated Instruction (IATPDI).” The items of IATPDI questionnaire were adapted from the pre-existing survey questionnaires and existing literatures on differentiated instruction. To quantify content validity of IATPDI questionnaire, a pre-developed survey questionnaire with 40 items was emailed to two established content experts to: (1) rate each item in terms of its clarity and relevancy to the measured domain; (2) evaluate which item should be deleted or revised; and (3) get recommendation about whether additional items are needed to

adequately tap the domain of interest. The Delphi method was used to collect the data. Subsequently, two rounds of Delphi process culminated in a revised and refined IATPDI questionnaire with 40 simplified items divided into four sections. Content validity of IATPDI questionnaire was quantified by calculating content validity index (I-CVI and S-CVI) and modified kappa statistics, which indicated high content validity of the 40 items. Taken together, the results show that the IATPDI questionnaire is a content valid instrument.
Effectiveness of Group Work in the Colleges of Royal University of Bhutan
Authors: Utha Karma , Tshering Tshering
Published: March 2022

Group work has become an essential assessment practice to enhance students' learning and develop social skills in all higher education

institutions. The study was undertaken to find out the effectiveness of group work. A mixed method sequential explanatory design was

adopted with 181 tutors and 1241 students of nine constituent colleges of Royal University of Bhutan. The findings revealed that the students

prefer group work and were aware of its benefits. However, the individual and group accountability were lacking leading to the presence of free riders. Further, awarding the same grade on a task irrespective of individuals’ contribution has led to increased free riders resulting in preference of individual tasks. Unless documentation is used for fair assessment, giving the same grade is seen as not a viable

option in the current practice. Also, group work lacked interdependence due to division of work among members leading to limited opportunities for students to collaborate and enhance their social skills. Some of the recommendations are: to pay attention to group work design to promote interdependence in enhancing learning and social skills; to use documentation as evidence for group work assessment to minimize free riders; and to conduct a study to find out whether use of documentation in group work assignments leads to individual

accountability.
