Vascular plant one-zinc-finger (VOZ) transcription factors regulate plant growth and development under drought conditions. Six VOZ transcription factors encoding genes exist in soybean genome (both in Glycine max and Glycine soja). Herein, GmVOZs and GsVOZs were identified through in silico analysis and characterized with different bioinformatics tools and expression analysis. Phylogenetic analysis classified VOZ genes in four groups. Sequence logos analysis among G. max and G. soja amino acid residues revealed higher conservation. Presence of stress related cis-elements in the upstream regions of GmVOZs and GsVOZs highlights their role in tolerance against abiotic stresses. The collinearity analysis identified 14 paralogous/orthologous gene pairs within and between G. max and G. soja. The Ka/Ks values showed that soybean VOZ genes underwent selection pressure with limited functional deviation arising from whole genome and segmental duplication. The GmVOZs and GsVOZs were found to express in roots and leaves at seedling stage. The qRT-PCR revealed that GmVOZs and GsVOZs transcripts can be regulated by abiotic stresses such as polyethylene glycol (PEG). The findings of this study will provide a reference to decipher physiological and molecular functions of VOZ genes in soybean.
Psychological distress in late adolescence: The role of inequalities in family affluence and municipal socioeconomic characteristics in Norway
Authors: Haugan Tommy , Muggleton Sally , Myhr Arnhild
Published: July 2021

The present study aims to explore, in the national context of Norway, how municipal socioeconomic indicators affect anxiety and depressive symptom scores among senior high school students and whether this potential municipal effect is dependent on the adolescents’ family affluence levels. This cross-sectional study is based on questionnaire data collected in five waves (2014–2018) of the Ungdata survey. The study sample consisted of 97,460 adolescents aged 16–18 years attending high school in 156 municipalities in Norway. Measures of psychological distress, depression, and anxiety symptoms were based on the screening instrument, Hopkins Symptom Checklist-10. Two-level random intercept models were fitted to distinguish the individual and municipality sources of variation in adolescents’ mental health. In general, the results indicate substantial psychological symptom load among the study sample. Inequalities in adolescents’ psychological distress between family affluence groups were evident, with the lowest symptom loads in the most affluent families. The predicted depressive and anxiety symptoms among the students increased slightly along with the percentage of municipal residents with tertiary educations and with increasing income inequalities in their residential municipality. However, the interaction models suggest that the adverse effects of higher municipal education level and greater income inequality are, to a certain extent, steepest for adolescents with medium family affluence. This study highlights two key findings. Both municipality effects and family affluence account for a relatively small proportion of the total variance in the students’ psychological symptoms loads; however, the mental health inequalities we explored between socioeconomic strata on both the individual and municipal levels are not insignificant in a public health perspective. Results are discussed in the context of psychosocial mechanisms related to social comparison and perceptions of social status that may be applicable in egalitarian welfare states such as Norway.

During archaeological excavations in burial sites, sometimes stoned organic objects are found, in addition to human remains. Those objects might be of a different origin, depending on various factors influencing members of a community (i.e. diseases, trauma), which provides information about their living conditions. The St. Nicholas Church archaeological site (Libkovice, Czechia) in the 18th century horizon of the cemetery, yielded a maturus-senilis female skeleton with a stone object in the left iliac fossa. This object was an oviform cyst-like rough structure, measuring 54 mm in length, 35 mm in maximum diameter and 0.2–0.7 mm shell thickness. Within the object there were small fetal bones (long bones, i.e. femur and two tibias, two scapulas, three ribs, vertebrae and other tiny bone fragments). Methods utilized to analyze the outer and inner surface morphology of the cyst and its inside, included: X-ray, CT imaging, SEM, histological staining and EDS. The EDS analysis revealed the presence of primarily oxygen, calcium and phosphorus in bone samples, and oxygen and silicon, in stone shell. Based on the length of the femur (20.2 mm) and tibia (16 mm) shafts, the fetal age was determined as being in the 15–18 week of pregnancy. The differential diagnosis was conducted, including for the three most probable cases: fetiform teratoma (FT), fetus-in-fetu (FIF) and lithopedion. The possibility of fetiform teratoma was discounted due to the presence of an anatomically correct spine, long bones and the proportions of the find. Although the low calcium content in the shell (2.3% atom mass), the lack of skull bones and the better developed lower limbs indicate fetus-in-fetu rather than lithopedion, the analyses results are unable to conclusively identify the object under one of these two categories since there are insufficient such cases in excavation material with which to draw comparison.

Published: July 2021

A toracocentese consiste em um procedimento diagnóstico fundamental para pacientes com derrame pleural de causa desconhecida, através da correta interpretação da análise do líquido pleural. O líquido puncionado deve ser avaliado laboratorialmente e classificado. O transudato geralmente é devido a alterações no controle do fluido corporal, enquanto o exsudato é frequentemente causado por processo inflamatório ou maligno. Apesar de ser considerado um procedimento pouco invasivo, é fundamental que a toracocentese obedeça a uma técnica padronizada com a finalidade de aprimorar a chance de diagnóstico e minimizar riscos. Neste trabalho, apresentamos uma revisão anatômica e fisiológica sobre a formação do derrame pleural, bem como a técnica, os materiais necessários e as complicações da toracocentese.
Analyzing the adoption of radiofrequency ablation of thyroid nodules using the diffusion of innovations theory: understanding where we are in the United States?
Authors: Kuo Jennifer H. , McManus Catherine , Lee James A.
Published: July 2021

Thyroid nodules are very common and found in up to 68% of the general U.S. population on ultrasound. Although thyroidectomy has long been the mainstay of treatment for malignant and symptomatic benign thyroid nodules, various interventional ablative techniques have emerged in the last couple of decades as alternative non-surgical treatment options. Globally, the most widely adopted technique has been ultrasound-guided radiofrequency ablation (RFA). RFA of thyroid nodules was first performed in 2002, and there has been an expanding body of evidence since 2006 showing that RFA and other interventional ablative techniques are effective treatments for benign solid thyroid nodules, toxic adenomas, and thyroid cysts. More recently, evidence has emerged that these techniques may be effective treatment for low-risk thyroid cancer and recurrent disease. Despite these findings, the United States has been slow to adopt these techniques, with only a single publication on RFA more than a decade after the first series was published. EM Rogers’ Diffusion of Innovation Theory provides us the appropriate lens to carefully analyze the process of adoption of RFA for thyroid nodules-to understand where we are currently, as well as, the important next steps that must be accomplished in order for RFA and other ablative techniques to be successfully adopted into the management algorithm of thyroid nodules in the United States.

Pricing of Participating Forward Contract
Authors: Dchieche Amina
Published: July 2021

The purpose of this work is to model a participating forward contract permitting to avoid unlimited risk and unknown loss using a formula of risk sharing that includes the payment of an additional amount under specific price variations. This contract offers a new tool that Islamic finance can use since this finance is suspicious of classical forward contracts. The modeling is based on the classical forward equation, which incorporates the profit and loss sharing principle derived from Islamic finance. The participating forward is tested on oil data prices to compare the participating forward contract to the classical one. The participating forward offers a better possibility of profit to the seller and the buyer because of the PLS mechanism which reduces the risk for both parties. The main implication of this modeling is that the participating forward can provide some investors and Islamic banks with an alternative to conventional forward contracts.
Uninterrupted VPN Connection Service with Mobility Management and Dead Peer Detection
Authors: Hudda Shreeram
Published: July 2021

The VPN technology is used to connect client devices securely over unsecured public networks. The Connection handover and Dead Peer Detection (DPD) are the most challenging and important tasks in VPN. In this present article, a solution for connection handover is proposed which covers the pre-authentication with new credentials for a mobile device prior to connection handover. In VPN, a case where such connection handover is failed due to incomplete connection handover or several unusual events which make a VPN client to become offline or dead. To address DPD issues a solution is proposed which includes a Keep Alive Timer (KAT) server at the VPN server side. This proposed solution for DPD is far better than an already existing solution that uses a DNS server for DPD since the DNS server faces several attacks consistently. Thus, the proposed solution for DPD is more secure against such vulnerable attacks.

Published: July 2021

Software in loop simulation (SILS) based waypoint navigation test platform being presented in this paper for fixed wing unmanned aerial vehicle. The proposed platform helps to test waypoint navigation algorithm before implementing into real time environment. Matlab/Simulink and X-plane flight simulator are chosen for the proposed platform. The interface between these two platforms are done by using user datagram protocol (UDP). The waypoint navigation which is to be tested is run in Matlab/Simulink environment where as fixed wing model runs in X-plane simulator. Inverted T tail fixed wing unmanned aerial vehicle configuration is chosen for this research work to verify both its inner loop (attitude control) and outer loop (navigation control). Navigation algorithm executed in Matlab/Simulink compares difference between current and desired latitude longitude position to command flight simulator to reach its desired waypoint. Navigation towards a desired waypoint will be achieved by varying inner loop attitude command of an unmanned aerial vehicle. Finally results are observed and performances are verified in X-plane simulator.

Published: July 2021

This paper is about the designing of 3-loop structure based fuel flow controller (FFC) for efficient operation of supersonic ramjet based propulsion system. The main objective of the control design is to vary appropriately the engine controllable parameters (throttle value area) such that commanded thrust is achieved by ramjet engine without endangering the engine stability and performance. Various factors such as combustion-intake interaction, atmospheric disturbance and other flight conditions have a significant impact on the air intake operation which lead to effect on engine performance. Due to above effect, intake un-start and buzzing phenomena can occur due to back pressure fluctuation and it disturb the intake pressure recovery and air mass flow rate. So, back pressure based extra loop introduce in 2-loop FFC design to have tight control on back pressure margin for smooth and efficient operation of air intake without need of extra hardware.

Published: July 2021

The pandemic of COVID-19 has significantly impacted the tourism industry in worldwide. The main objective of this research was to explore the desire of virtual museums tourists during the quarantine regulation under impact of COVID-19 pandemic. In this light, we considered the four main step of the quarantine lockdown phase in Spain. During these phases the availability of six types of virtual museums were evaluated to figure out the visitors’ interest. The results were obtained by analysing the number and kind of the visits being recorded in the virtual museum’s tours while Spanish inhabitation used to stay at homes for long days, weeks and even months. According to the results, in the zero-quarantine phase, the highest amount of visitors tend to visits the museum parks. While the science museums were received less visits. However, overall results indicated that the reduction of strictures during the quarantine period while the intensity of people's interest were decreased. Based on the results, we conclude that this research makes significant contribution for tourism research and will benefit the decision makers and stakeholders for developing virtual tourism industry further. We also conclude that for new approaches in the post-corona, special attention should be paid to the new interest developed by tourists during the quarantine period.

Published: July 2021

The development of technology, climate change as well as the cultural and social changes cause people to change their behavior, modify priorities and adapt to the new situation. Effectiveness and competitiveness, therefore, require up-to-date information on the market participants and factors affecting their behavior. As such, the aim of this article is to illustrate the impact of the weather conditions on participants’ attendance at various urban outdoor events, crucial for a leisure market. The study presents the relationship between the number of residents and tourists visits at the St. Dominic’s Fair in Gdańsk during individual days of the event and the weather conditions (temperature, precipitation, and sunlight intensity). As one of the data illustration methods, mobile phone-base-station logs were used to analyze consumer behavior. The study proved varying behavior of the residents and the tourists participating in the same event under different weather conditions emphasize these two diverse target markets’ complementarities.

How Do Undergraduate Tourism Students Perceive the Service Quality in their Educational Institution? An Assessment Using the SERVQUAL Framework
Authors: FUCHS Kevin
Published: July 2021

Tourism education is an important component and contributor to the tourism industry's global success, particularly as technology and innovation become more prevalent in the hospitality and tourism sectors around the world. Several studies have been conducted on student perceptions of tourism education and the tourism industry's long-term viability in the current and future environment. The importance of a capable, competent, passionate, and dedicated workforce in the service industries in general, and the tourism industry in particular, cannot be overstated. Related studies have also suggested that in the service sector, workers' optimistic attitudes about their work are critical for customer loyalty and satisfaction. Service quality and customer service are leading principles in the business world. Assessing educational service quality is important for encouraging and providing feedback on the effectiveness of educational plans and their execution as higher education institutions compete for competitive advantages and high service quality. In a number of universities, as well as further afield, monitoring student satisfaction with education quality has become an important part of the educational process. This study shows how to use the SERVQUAL system to measure student satisfaction in a more effective way.It entails the use of the SERVQUAL methodology to query and survey five factors related to student services. The proposed instrument was tested on 400 undergraduate tourism students at a large regional university in Thailand. The approach's utility in collecting tourism students' impressions, evaluating them, and reducing them to a form usable by management as an off-the-shelf service quality evaluation tool is demonstrated by rigorous study.

Published: July 2021

Myriostachya is a monotypic genus in the family Poaceae, with the only known species Myriostachya wightiana (Nees ex Steud.) Hook.f. It is a mangrove associate grass primarily distributed along the muddy streams and channels in intertidal mangrove swamps of India, Bangladesh, Sri Lanka, Myanmar, Thailand and Sumatra. Molecular identification and evolutionary studies of M. wightiana is unreported till now. Therefore, in this study, the phylogenetic analysis of M. wightiana was established with related family members by using chloroplast rbcL gene-based systematics. The molecular phylogeny was accomplished by DNA extraction, PCR amplification and sequencing of the rbcL gene and phylogenetic analysis. The genomic DNA was extract using the CTAB method and the rbcL gene amplification is by using the F-5IATGTCACCACAAACAGAAACTAAAGC3I and R-5ICTTCGGCACAAAATAAGAAACGATCTC3I primers. Phylogenetic analysis of M. wightiana was performed by multiple sequence alignment with UPGMA, and the Maximum-parsimony phylogenetic tree was constructed using MEGAX. Myriostachya wightiana rbcL gene sequence shows the highest similarity to Paspalum species, and in the phylogenetic tree M. wightiana has a close branch with Paspalum vaginatum. The evolutionary divergence from M. wightiana is maximum (0.49) to Sorghum propinquum and minimum (0.01) to Oryza officinalis and Oryza punctata. This study concluded that M. wightiana has a strong morphological and phylogenetic relationship with salt-tolerant Paspalum sp.

Wstęp. Przekład intersemiotyczny w poezji Europy Środkowej w XX wieku
Authors: Stankowska Agata , Szewczyk-Haake Katarzyna
Published: July 2021

For years, Porówania has focused on diverse correspondences between cultures, ethnic literatures, areas of art, inhabitants of various geographical spaces, imagined communities, contemporary discourses, etc. This volume is dedicated to the conversational strategies artists established between language and the visual arts, but also to the broader, and often variously defined, area of Central Europe. We were interested in the relationship between different (thematically and functionally) intersemiotic translation strategies with regard to cultural events and changes in the socio-political life of Central European nations, dominant communities and ethnic minorities. We also wanted to address the similarities and differences visible in this area on the basis of the different literatures and art (domestic and emigration; high-art and popular art). The selected case studies gathered in this volume are meant at least initially to outline a map of diverse intersemiotic relations, the coordinates of which are determined, on the one hand, by the broadly understood category of visibility and, on the other, by the cultural, social, political changes imposed on the Central European nations and communities they helped form. We wanted to ask the following question: does the changeability of the intersemiotic phenomena and theories justify the strength of the caesura, which we used to take for granted in ethnic literatures of this part of Europe? Does it help to better describe the “isms,” which have been developed by modern art and literature?
Literatura niemiecka po przełomie 1989/1990 roku. Przypadek Dursa Grünbeina
Authors: Kałążny Jerzy
Published: July 2021

Urodzony w 1962 roku w Dreźnie Durs Grünbein należy do najbardziej rozpoznawalnych poetów i eseistów niemieckich w pozjednoczeniowych Niemczech. Jego liczne zbiory poezji i esejów przetłumaczono na wiele języków, m. in. angielski, francuski, rosyjski, hiszpański, japoński i polski. W artykule został przedstawiony pierwszy okres kariery Grünbeina: od debiutu w 1988 do końca lat dziewięćdziesiątych, na tle dekompozycji krajobrazu literackiego Niemiec w okresie pozjednoczeniowym. Najważniejsze zagadnienia poruszone w tym kontekście to kształtowanie się oryginalnego stylu pisarstwa i poglądów estetycznych Grünbeina, łączenie przezeń literatury z nauką oraz poetyckie opracowanie doświadczenia życia w NRD. Tradycje europejskiego modernizmu i antyku, przekonanie o potrzebie autonomii i niezaangażowania poezji oraz o fragmentarycznym charakterze doświadczenia rzeczywistości stworzyły w latach dziewięćdziesiątych fundament tożsamości artysty, który w zasadzie przetrwał nienaruszony następne dziesięciolecia.
Бег ползком (Тараканья тема в русской литературе девятнадцатого–начала двадцатого века и в творчестве Михаила Булгакова)
Authors: Яблоков Евгений
Published: July 2021

В статье рассмотрен инсектный дискурс булгаковских произведений (рассказ Таракан, пьесы Бег и Адам и Ева) в сопоставлении с русской литературной традицией девятнадцатого–двадцатого веков. Прослежено развитие “тараканьей” темы в творчестве писателя середины 1920-х гг. – в частности, показана роль рассказа Таракан в формировании замысла Бега. “Тараканьи” мотивы в произведениях Булгакова сопоставляются с сюжетами ряда его предшественников и современников – Ивана Мятлева, Федора Достоевского, Иеронима Ясинского, Максима Горького, Аркадия Аверченко, Корнея Чуковского, Евгения Замятина, Бориса Лавренёва и др.;отмечены взаимосвязи между ними. Сравнительный анализ позволяет углубить представление о роли инсектного кода в поэтике Булгакова, внести существенные уточнения в интерпретацию ряда его произведений.
Rembrandt i samotność Chrystusa: *** [Tak jak męczennik światłocienia – Rembrandt…] Osipa Mandelsztama i Ewangelia także jako arcydzieło literatury Aleksandra Wata
Authors: Śniedziewska Magdalena
Published: July 2021

W artykule staram się opisać pomijane dotychczas przez badaczy relacje między tekstami a postaciami pojawiającymi się na płótnach Rembrandta. Interesuje mnie związek pomiędzy wierszem Mandelsztama *** [Tak jak męczennik światłocienia – Rembrandt…], szkicem Wata Ewangelia także jako arcydzieło literatury a Rembrandtowskim wyobrażeniem Chrystusa oraz – co istotne w przypadku Wata – batawskiego wodza, Claudiusa Civilisa. Przykłady utworów Mandelsztama oraz Wata pokazują, że dzieło Rembrandta nie tylko może posłużyć do wyrażania osobistych lęków, ale pozwala też uporządkować relacje między jednostką a historią – staje się zatem wyzwaniem nie tylko estetycznym, ale i egzystencjalnym. Dowodzę także, iż twórczość Mandelsztama i Wata, tak silnie powiązana z tragicznym losem tych poetów, znalazła swoją kulminację w ich śmierci.
W świetle powyższej (pobieżnej) analizy: Studium fotografii w Komentarzach do fotografii Witolda Wirpszy
Authors: Zalewski Cezary
Published: July 2021

Artykuł przedstawia sposób powiązania fotografii i poezji na przykładzie czterech utworów z Komentarzy do fotografii Witolda Wirpszy. Wyróżnione i zanalizowane zostały trzy obszary wzajemnych interakcji: (a) zasada funkcjonowania foto-tekstualnego dyptyku i rola, jaką pełni tu poetycki opis; (b) zasada analogii formalnej, zgodnie z którą niektóre parametry monologu lirycznego mają swoje źródło w formalnych właściwościach zdjęcia; oraz najważniejsza (c) zasada transformacji znaczeń kompozycyjnych. Polega ona na dwustopniowej interwencji: tekst poetycki najpierw stara się zneutralizować wizualne znaczenia kompozycyjne (faza negatywna), a następnie stwarza własną interpretację fotografii (faza pozytywna).

A microstrip planar lowpass filter with ultra-wide stopband using hexagonal-shaped resonators
Authors: Jiang Shu , Wang Wenbo , Ren Le
Published: July 2021

A microstrip planar lowpass filter with ultra-wide stopband up to 40 GHz is presented. The filter is designed based on four types of hexagonal-shaped resonators, producing multiple transmission zeroes and extending the stopband. The high-impedance transmission line is folded to make the circuit more compact and form the coupling gaps between the adjacent resonators. A pair of folded open stubs are added to enhance the cut-off rate. As a result, an ultra-wide stopband with 23rd-harmonic suppression has been attained.

Since the development of GNSS techniques, the determination of a precise quasi-geoid model has become even more actual. In terms of this project the staff of the Institute of Geodesy and Geoinformatics (GGI) has developed a new quasi-geoid model based on DFHRS (Digital Finite-element Height Reference Surface) approach additionally using astrogeodetic measurements – vertical deflections (VD), which can be observed by a Digital zenith camera. This paper evaluates a quasi-geoid model results based on vertical deflections, as a study area using the territory of Latvia: the standard deviation of the solution is equal to 0.006 m with observation residuals after the adjustment of minimum and maximum differences −0.012 and 0.012 accordingly. The standard deviation of quasi-geoid heights and h-H values from LGIA database is equal to 0.012 m with minimum and maximum differences −0.026 and 0.025 accordingly. The post-processed terrestrial VD observations have been compared to VD derivatives from EGM2008 and GGMplus geopotential models. The developed quasi-geoid has been compared to the national quasi-geoid model LV’14 and to the Scandinavian NKG2015.

Authors: Mudaliana Siti
Published: July 2021

Objectives

Antibiotic treatments can create multi-drug resistance among several pathogens. There is a need for an antibiotic alternative to overcome this problem. In Indonesia, Centella asiatica (Asiatic pennywort) and Gigantochloa apus (string bamboo) are two common medicinal plants used to treat tuberculosis, diarrhea, and other symptoms. This study was done to compare the antimicrobial activity of C. asiatica and G. apus against five pathogenic bacteria, i.e., Mycobacterium tuberculosis H37Rv strain, Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Salmonella typhi.

Methods

The ethanol extracts of C. asiatica, and G. apus shoot were obtained by using speed extractor, pressure, and temperature extraction. The phytochemical contents of each extract were screened. The ethanol extract’s antimycobacterial activity was determined using Lowenstein Jensen (LJ) medium and antibacterial activity was determined using Kirby–Bauer methods on Mueller Hinton agar (MHA).

Results

The phytochemical analysis showed that G. apus extract contains alkaloids and tannins, whereas C. asiatica extract contains flavonoids, alkaloids, saponins, and tannins. This study showed that G. apus inhibited the growth of M. tuberculosis H37Rv strain and S. typhi. C. asiatica showed antimicrobial activity against all pathogenic bacteria tested, except B. subtilis.

Conclusions

Both medicinal plants extract can inhibit the growth of five pathogenic bacteria tested, thus, have the potential as an alternative treatment, or complementary, to treat the pathogenic bacterial infection.

Authors: Eryani Mikhania Christiningtyas , Hendradi Esti , Siswandono
Published: July 2021

Objectives

This study aimed to evaluate the variation concentration effect of propyleneglycol, glycerin, and polyethyleneglycol 400 as a nonvolatile solvent on the physical properties and dissolution rate of the loratadine liquisolid tablet.

Methods

The tablet was formulated into 10 formulas, where nine were liquisolid and one was conventional (CT). The concentration of propyleneglycol, glycerin, and polyethyleneglycol used in liquisolid tablets were 14, 15, and 16%. Furthermore, the mixture was evaluated based on flow properties and compressibility index. The tablet was evaluated based on hardness, friability, disintegration time, and dissolution, and the data obtained was evaluated with ANOVA or Kruskal–Wallis statistic program.

Results

The result showed that flow properties, disintegration time, and dissolution have a significant value less than 0.05. The tablet friability for all concentration solvents, hardness at 14 and 15% solvent concentration, and compressibility index at 15 and 16% have significant value more than 0.05. The 16% propyleneglycol type solvent concentration tablet has the physical properties and contains the best solution

Conclusions

From the result, it is reasonable to conclude that F7 is the tablet with all the physical properties and the best dissolution.

Published: July 2021

Objectives

This study aims to synthesize a series of benzoxazines (1–5) to be examined as an epidermal growth factor receptor (EGFR) inhibitor by in-silico study. The overexpression of EGFR causes the growth of normal lung cells to become uncontrollable, which may lead to cancer formation. We also conducted the absorption, distribution, metabolism, excretions and toxicity (ADMET) properties evaluation and also examined in vitro anticancer assay on human lung cancer cells line, which is A549.

Methods

Benzoxazines (1–5) were synthesized by reacting anthranilic acid and benzoyl chlorides. The structures of the compounds were determined with 1H, 13C-NMR, HRMS, UV and FT-IR spectrometric methods. Prediction of ADMET was using online pkCSM, and the molecular docking studies were using MVD with EGFR-TKIs as the target (PDB ID: 1M17). In vitro assay of anticancer activity was performed by MTT assay.

Results

Compounds 1–5 were successfully synthesized in good yields (71–84%). The ADMET prediction showed that benzoxazines are able to be absorbed through GIT, metabolized by CYP 450, and not hepatotoxic. The title compounds have a greater Moldock Score than Erlotinib, and 3 has the highest activity against A549 compared with other benzoxazines, IC50=36.6 μg/mL.

Conclusions

Compound (3) more active as anticancer against Human cancer cells line compared with other benzoxazines.

Published: July 2021

Objectives

For designing early treatment for liver cancer, it is important to prepare an animal model to evaluate cancer prevention treatment by using inflammation disease. The hepatocarcinogenic N-Nitrosodiethylamine (NDEA) has been reportedly able to produce free radicals that cause liver inflammation leading to liver carcinoma. This study aimed to evaluate the inflammation disease model of mice induced with hepatocarcinogenic NDEA for five weeks induction.

Methods

The BALB-c mice were induced with NDEA 25 mg/kg of body weight once a week for five weeks intraperitonially and it was then evaluated for the body weight during study periods. The mice were then sacrificed and excised for evaluating their organs including physical and morphological appearances and histopathology evaluations.

Results

The results showed a significant decrease of body weight of mice after five times induction of 25 mg NDEA/kgBW per week intraperitonially. Different morphological appearances and weight of mice organs specifically for liver and spleen had also been observed. The histopathology examination showed that there were hepatic lipidosis and steatohepatitis observed in liver and spleen, respectively that might indicate the hepatocellular injury.

Conclusions

It can be concluded that inducing mice with NDEA intraperitonially resulted in fatty liver disease leading to progress of cancer disease.
El estado espiritual y temporal de los indios de la jurisdicción de San Luis de la Paz según las autoridades religiosas, 1790-1803

Published: July 2021

En este artículo se presenta un estudio detallado en torno a las perspectivas que diversas autoridades religiosas plasmaron sobre los indios de tres rancherías en la entonces jurisdicción de San Luis de la Paz, a los que se buscaba congregar en la Misión de Arnedo, durante los últimos años del siglo XVIII y los primeros años del siglo XIX. A través de este artículo, se busca destacar la forma cómo los religiosos, tanto los frailes del Colegio Apostólico de San Pedro y San Pablo de Michoacán como los párrocos, representaron la vida de los indios en las inmediaciones del poblado de San Juan Bautista de Xichú de Indios.
De la Tierra sin historia a la historia de la Tierra. El uso de la evidencia geológica en la elaboración y el desarrollo de escalas de tiempo naturalizadas durante los siglos XVII y XVIII
Authors: Del Razo Canuto Carlo
Published: July 2021

El presente artículo es un análisis histórico-filosófico acerca de cómo se fueron desarrollando las principales ideas conceptuales, epistemológicas, metodológicas, así como los recursos cognitivos que permitieron plantear por primera vez en la ciencia moderna que la Tierra tenía una historia propia e independiente a la historia humana. Mi argumento es que el estudio de los fósiles y el de los estratos geológicos llevaron a la formulación de nuevas e inéditas ideas acerca de los procesos de transformación geológica y de fosilización en los siglos XVII y XVIII. La investigación de este segmento del mundo natural fue el antecedente que permitió establecer las primeras condiciones de posibilidad para que en el siglo XIX se aceptara que la edad de la Tierra era más antigua que el cálculo basado en las cronologías bíblicas, lo cual representó un nuevo problema métrico.
La agricultura como puente. Becarios guatemaltecos de la Fundación Rockefeller en México: un viaje de ida y vuelta, 1949-1976
Authors: Méndez Rojas Diana Alejandra
Published: July 2021

El artículo expone los resultados de una investigación centrada en el estudio de las trayectorias de los guatemaltecos que, apoyados por el Programa de Becas de la Fundación Rockefeller, completaron capacitaciones avanzadas o estudios de posgrado en ciencias agrícolas en México, entre 1949 y 1976. Desde el mirador de la historia del intercambio académico, en clave transnacional, se propone que la agricultura fungió como un puente que —a través de los itinerarios de los becarios— unió dos procesos: la profesionalización de la enseñanza agrícola en México y la profesionalización de la investigación agrícola en Guatemala. Se argumenta, además, que ambos procesos formaron parte del despliegue de la revolución verde en América Latina. Esta indagación se fundamentó en la consulta de fuentes primarias, hemerografía y entrevistas.

Authors: Gil Guillermo Rebollo
Published: July 2021

This article offers an account of the author’s experience after being falsely accused online of sexual assault by a former student. More than a chronicle of events, the article serves as a critical, self-reflexive inventory of thoughts and feelings, as the author looks to come to terms with the allegations and their consequences, as well as practice concern for his accuser. More broadly, the essay serves as an inquiry into the complexities of storytelling and self-research, in relation to shame, truth, and social privilege.
The Rituals of Pain
Authors: Frausto Mario
Published: July 2021

In this autoethnographic text I talk about my relationship with my father and my older brother as a way of analyzing the construction of my masculinity. In addition, I use the layered-account technique to alternate my personal history with fragments of texts that talk about masculinity as a social construction. In this way, I propose to turn my story into a way of showing how hegemonic masculinity is constructed through pain and violence as the bases of this gender identity.
