PsA inhibits the development of bovine embryos through epigenetic and oxidative stress
Authors: Ma Xin , Zhan Chenglin , Ma Panpan , Jing Guo , Liyan Su , Zhang Yanlin , Jing Zhao , Liu Hongyu , Wang Jun , Lu Wenfa
Published: February 2023

OBJECTIVE

Histone deacetylases (HDACs) are the key regulators involved in the process of embryo development and tumor progression and are often dysregulated in numerous disordered cells, including tumor cells and somatic cell nuclear transfer (SCNT) embryos. Psammaplin A (PsA), a natural small-molecular therapeutic agent, is a potent histone deacetylase inhibitor (HDACi) that alters the regulation of histone.

SAMPLES

Approximately 2,400 bovine parthenogenetic (PA) embryos.

PROCEDURES

To investigate the effect of PsA on bovine preimplanted embryos, we analyzed the preimplantation development of PA embryos treated with PsA in this study.

RESULTS

The blastocyst formation rate of bovine PA embryos decreased sharply with an increase in concentration and duration. Furthermore, the expression of the pluripotency-related gene Nanog was decreased, and the inhibitory effects on histone deacetylases 1 (HDAC1) and DNA methylation transferase 1 (DNMT1) were observed in bovine PA embryos. The acetylation level of histone H3 lysine 9 (H3K9) was enhanced by a PsA treatment of 10 μM for 6 h, while the DNA methylation appeared unchanged. Interestingly, we also found that PsA treatment enhanced the intracellular reactive oxygen species (ROS) generation and decreased the intracellular mitochondrial membrane potential (MMP)- and superoxide dismutase 1 (SOD1)-induced oxidative stress. Our findings improve the understanding of HDAC in embryo development and provide a theoretical basis and reproduction toxicity evaluation for the application of PsA.

CLINICAL RELEVANCE

These results indicate that PsA inhibits the development of bovine preimplantation PA embryos, supplying data for the PsA clinical application concentration to avoid reproductive toxicity. In addition, the reproduction toxic effect of PsA may be modulated through increased oxidative stress on the bovine PA embryo, suggesting that PsA in combination with antioxidants, for example, melatonin, might be an effective clinical application strategy.

Published: February 2023

The origins of scientific nature collections in Wielkopolska (Western Poland) date back to the seventeenth century. Their development was repeatedly disrupted by major events, including two world wars fought in Poland in the twentieth century. The rescued historical collections as well as specimens of algae, plants, fungi and animals systematically collected after 1945 are now stored under optimal conditions at the Faculty of Biology of Adam Mickiewicz University in Poznań (FBAMU). The current collections include approximately 2.2 million pre-catalogued objects that document not only the biodiversity of Wielkopolska and Poland but also that of many regions of the world on all continents. Specimens included in the FBAMU are used extensively in taxonomic, biogeographic, phylogenetic, ecological and genetic studies. The collections also have significant educational value and help disseminate knowledge about biodiversity.

Carex brunnescens (Pers.) Poir. in Poland and in the neighbouring regions – in the past and at present
Authors: Kruk Jerzy
Published: February 2023

In the article, new and historical locations of Carex brunnescens (Pers.) Poir. from Poland and the neighbouring regions are described. This species was found in 2019 at two stands in north-eastern Poland – on the peaty shores of two small lakes; one situated in the Suwałki Landscape Park and the other in the Augustów Forest. Three historical records, supported by the herbarium materials, from the turn of the 19th and the 20th centuries, were situated in the Lower Vistula region (north-central Poland), i.e. in the vicinity of Kielno, Nowe and Susz. The literature data indicates the existence of many stands in the historical Eastern Prussia, one of which was situated south of the Romnicka Forest in Poland and all the others in the Kaliningrad region. Moreover, numerous incorrect reports from the Sudetes and the Carpathians were discussed. As Carex brunnescens is probably extinct at all the historical locations in the present territory of Poland, the species deserves special attention and protection at the two recently indentified stands.

Published: February 2023

Background

Solitary pulmonary nodules (SPNs) are one of the most common chest computed tomography (CT) abnormalities clinically. We aimed to investigate the value of non-contrast enhanced CT (NECT), contrast enhanced CT (CECT), CT perfusion imaging (CTPI), and dual- energy CT (DECT) used for differentiating benign and malignant SPNs with a multi-institutional and prospective study.

Patients and methods

Patients with 285 SPNs were scanned with NECT, CECT, CTPI and DECT. Differences between the benign and malignant SPNs on NECT, CECT, CTPI, and DECT used separately (NECT combined with CECT, DECT, and CTPI were methods of A, B, and C) or in combination (Method A + B, A + C, B + C, and A + B + C) were compared by receiver operating characteristic curve analysis.

Results

Multimodality CT imaging showed higher performances (sensitivities of 92.81% to 97.60%, specificities of 74.58% to 88.14%, and accuracies of 86.32% to 93.68%) than those of single modality CT imaging (sensitivities of 83.23% to 85.63%, specificities of 63.56% to 67.80%, and accuracies of 75.09% to 78.25%, all p < 0.05).

Conclusions

SPNs evaluated with multimodality CT imaging contributes to improving the diagnostic accuracy of benign and malignant SPNs. NECT helps to locate and evaluate the morphological characteristics of SPNs. CECT helps to evaluate the vascularity of SPNs. CTPI using parameter of permeability surface and DECT using parameter of normalized iodine concentration at the venous phase both are helpful for improving the diagnostic performance.

Анотація. У поточній дослідницькій статті автори розкривають поетапний механізм визначення метафор як репрезентантів перцептивно-образного елемента концепту НЕЗАЛЕЖНІСТЬ в сучасній американській свідомості. Розвідка виконана в контексті шарової моделі концепту українського вченого А.М. Приходька на дискурсивному матеріалі (мовне середовище свідомої об’єктивації концепту), скомпонованого в мінімодель – корпусну вибірку ілюстративних контекстів. Ресурсною базою для укладання вибірки послугував Corpus of Contemporary American English (COCA) як найбільш авторитетний і регулярно оновлюваний банк оцифрованих американських текстів. У ньому згенеровано конкорданс за запитом «independence», з якого випадково вилучені 150 контекстів актуалізації концепту НЕЗАЛЕЖНІСТЬ в сучасному американському соціумі. Обрані для студії ресурси автори опрацювали за методикою визначення концептуальних метафор Дж. Лакоффа і М. Джонсона в єдності з параметрами порядку метафоризації Н. В. Таценко – спаціальність, дименсіальність, дискретність, посесивність, артефактність, перцептивність, персоніфікація тощо. У результаті аналізу вибірки встановлено 24 метафори як актуалізатори перцептивно-образного шару концепту НЕЗАЛЕЖНІСТЬ в американському дискурсі: НЕЗАЛЕЖНІСТЬ є МІСЦЕ; ДВЕРНИЙ ЗАМОК; ФІЗИЧНЕ ТІЛО; ВОГОНЬ; ЗАВДАННЯ; МЕТА / ПРОДУКТ; РЕЗУЛЬТАТ; НОВОСТВОРЕНИЙ ОБ’ЄКТ; ДАТА; ВІДОКРЕМЛЕНИЙ СУБ’ЄКТ / ОБ’ЄКТ; СТАН СУБ’ЄКТА / ГАЛУЗІ; ВЛАСНІСТЬ; ВАРІАТИВНИЙ ОБ’ЄКТ; КОМПЛЕКСНИЙ ОБ’ЄКТ; РЕСУРС / ІНСТРУМЕНТ; МЕХАНІЗМ / МАШИНА; ЖИВИЙ ОРГАНІЗМ; ЛЮДИНА; ОБ’ЄКТ СПРИЙНЯТТЯ, ВІДЧУТТЯ / УЯВЛЕННЯ, АНАЛІЗУ, ПОШАНУВАННЯ або ЗНЕВАГИ; МИСЛЕННЄВИЙ ВИСНОВОК.

Authors: Quoc Thao Tran , Hoang Chau Long Nguyen
Published: February 2023

Listening is considered one of the most challenging language skills, so most of EFL learners find it difficult to get engaged in learning it. Various obstacles have been reported causing challenges for EFL learners in English listening comprehension. This study, therefore, aimed to explore EFL students’ learning engagement and their problems in English listening comprehension. The research was conducted at a high school in Ca Mau province, Vietnam with the participation of 180 tenth grade EFL students in answering the questionnaires. The collected quantitative data were analyzed using SPSS software. The findings revealed that EFL students got engaged in listening comprehension emotionally and agentically rather than behaviorally and cognitively, and their emotional engagement tended to be the most influential. It was also found out that EFL students sometimes faced different types of difficulties (perception problems, parsing problems and utilization problems) in their English listening comprehension.

Authors: Dinh Phuong Khanh Ho , Thi Nhu Ngoc Truong
Published: February 2023

The study investigates Vietnamese non-English-majored freshmen's speaking anxiety. 297 non-English-majored freshmen enrolled at a public university in Vietnam answered the Questionnaire of Speaking Anxiety. The results show that participants had a moderate level of English-speaking anxiety, with female students having a higher level of speaking anxiety than male students. To provide insights into sources of speaking anxiety, anxiety-provoking situations and strategies that students use to cope with speaking anxiety, follow-up qualitative data was collected. 24 students from the pool of participants were conveniently recruited and randomly assigned to five focus groups, who answered the semi-structured interview questions. The findings show that students experience a higher level of speaking anxiety when they are called to answer questions by their teacher in class and during a speaking test, and to make an oral presentation than when they perform a role-play in front of the class and work in groups. Besides, students attributed their speaking anxiety to their English-speaking abilities, the nature of teachers' questions, fear of losing face and being judged, and fear of receiving low scores. To cope with speaking anxiety, students reported using social and cognitive strategies. The study provides helpful information for English lecturers to understand the nature of students' speaking anxiety and help students tackle speaking anxiety.

Authors: Phuong Linh Tran , Minh Hoang Do
Published: February 2023

The study investigates the reliability and user feedback about the rubrics to evaluate English – Vietnamese consecutive interpreting tests taken by undergraduates at VNU-ULIS created by Tran and Do (2022). Five VNU-ULIS raters – two experienced raters and three novice ones – independently rated ten different interpreting tests and provided their feedback on the rubrics. The results reveal the newly created rubrics is mostly considered user-friendly and practical application for interpreting evaluation. Overall, inter-rater reliability, which was presented through Cronbach’s alpha and the single measure intra-class coefficient, was acceptable. Besides, the value among the novice raters was higher than that between the two experienced ones. The raters’ perception of each quality criterion and their rating process may account for the differences in their score decisions. The findings also suggest further improvements in terms of descriptor wording, weightings and rater training.

Published: February 2023

Metacognitive reading strategies which include (1) global reading strategies, (2) support reading strategies, (3) problem solving strategies are critical for effective reading comprehension (Mokhtari & Reichard, 2002). This research aims to explore how high-achieving and low-achieving students at Faculty of Foreign Languages at a university in Vietnam use metacognitive reading strategies in comprehending English reading texts. A mixed research method is employed with two data collection instruments - a survey questionnaire adopted from MARSI Scale by Mokhtari and Reichard (2002) and semi-structured interviews. Forty two English-majors participated in the questionnaire, then representatives of high-achievers and low-achievers participated in semi-structured interviews to provide deeper information. The findings revealed students’ different frequency levels of using metacognitive reading strategy groups in reading comprehension. Additionally, the results indicated how frequently each metacognitive reading strategy is used by the high-achievers and low-achievers. This research would enhance teachers’ awareness of using metacognitive reading strategies for English majors at their different levels and suggest how they instruct their students of different levels to practice metacognitive reading strategies appropriately and effectively.

The Deities of Arabs before Islam: Between Sanctification and Underestimation
Authors: Mafraji Waaddullah
Published: February 2023

The pagan religion was the most widespread religion in the region of the Arabian Peninsula before Islam. It was a religion that is based on the worship of a certain idol or monument, which they considered as their gods. The purpose of their worship was to obtain the approval of these gods and avoid their anger and resentment, and to obtain success in their socio-economic, religious and political lives. Therefore, these deities were revered. Before Islam, Arabs reached the limit of reverence for their gods to offer vows and offerings, and they reached the point of offering human, animal and material offerings. At the same time, these idols were exposed to abuse and underestimation by some people. The study shows how Arabs reverence their idols as well as underestimate them, and how do they reach to this duality in dealing with deities .

Published: February 2023

This article analyzes the flouting types of maxim in classroom interaction videos on YouTube. The aims of this study are to find out the flouting types of maxim and also the gender representation of it. Descriptive qualitative method was used. The corpus of the study were 10 classroom interaction videos that were taken from YouTube. Grice’s theory was used to find and analyze the flouting types of maxim found in the video, those are; maxim of quality, quantity, relevance, and manner. The result showed that those four types of flouting maxim were found in the classroom interaction videos on YouTube. The highest flouting maxims found were maxim of quantity, relevance and manner and the least one is maxim of quality. This is probably because the speaker wants to build trust and cheer the hearer. The findings of the second research question shows that male was the most dominant gender flouting the maxims. Based on the results and limitation of the study, it is recommended for further research to take the data directly to schools to compare videos taken from YouTube and those taken directly from schools.

Although teachers in Ethiopia are given pre-service training to upgrade their pedagogical knowledge and teaching proficiency, they may not be fully prepared for all the challenges they will face throughout their careers. This is particularly true in the current situation that requires teachers to be able to meet the changing needs of the current learners that use technology. The federal ministry of education has been making efforts to provide teachers at all levels concerning information communication technologies (ICTs) utilization in their educational activities.  In addition to the government–initiated training packages, teachers are expected to familiarize themselves with ICTs through their own self-initiated efforts. The purpose of this study was to investigate the use of ICTs in University EFL teachers’ Self-initiated professional development. The study participants were 35 EFL university teachers from Addis Ababa Science and Technology University. They were selected using total population sampling. Concurrent mixed methods were employed in the study. The data were collected using a questionnaire and semi-structured interviews. The data were then analyzed separately and finally mixed during the discussion of the data. The findings of the study indicated that teachers' beliefs about the use of ICTs in self-initiated professional development were positive.

This study aims to investigate EFL students’ perception of English Corner (EC) and how EC is constructively designed and developed in English Education at Galuh University as a non-credit course that consists of five programs that all participants might optionally select dealing with their interests and talent. Singing, poetry reading, storytelling, drama, and public speaking are sophisticated complete packages to predominantly uphold participants’ English performance due to English as the only language used in EC. It is as opposed to the preliminary EC that originated in China that was undertaken for the public elsewhere. However, EC at Galuh University consists of the statement of the problem of this study consists of finding out how EC using creative work is developed and investigating EC participants’ perception of participating in EC using creative work. This is the exploration of the case study because EC has been practiced for the last four semesters in English Education. The data to be analyzed were collected from the observation and questionnaire from 40 participants of EC and the data analysis used Triangulation. The findings showed that all facilitators and participants get involved to opt, adjust and match the materials over steps and strategy. They opt for one of the programs following their interest and talent. Based on the questionnaire computation using SPSS, from the highest scale 5, the average of participants’ responses is 4,43 for improving their English vocabulary, 4,4 for improving their English speaking skills, 4,35 for improving their English grammar, 4,38 for affecting other academic courses, and 4,38 of dismissing their fear of making mistakes in using English vocabulary. In conclusion, EC using creative work is beneficial to use and it can be a booster and supplement to support participants’ English performance.

Один из самых сложных моментов в изучении московских живописных изразцов XVIII в. это определение их изготовителя. Счастливым исключением могут быть изразцы, сделанные в отдаленных от центра городах с единственным изразцовым заводом, продукция которого была узнаваема в силу своих особенностей. В статье на основе опубликованных материалов, найденных новых архивных сведений, проведенных лабораторных исследований черепка, поливы и красок белоглиняных плиток и изразцов первой половины XVIII в. утверждается возможность атрибутировать последние как продукцию известной московской фабрики А. Гребенщикова.

One of the most complicated issues in studying 18th century Moscow painted ceramic tiles is to identify where they were produced. An exception to this rule are, luckily, tiles made in small remote towns with a single brickyard. Its production can then by identified by its specific look. Relying on published materials, new archival finds and laboratory studies of ceramic fragments, glazing and paint on white clay tiles produced in the first half of the 18th century, the article suggests that the tiles might have been made at the well-known Moscow brickyard owned by A. Grebenschikov.

Solid Pseudopapillary Neoplasms (SPN) of the pancreas are rare neoplasms representing 1-2% of all pancreatic tumors, and considered as low-grade malignancies. This pathology mainly affects young women. Its prognosis is usually excellent when the tumor is limited to the pancreas, with a cure rate greater than 95% after a complete surgical resection. Preoperative diagnosis is always difficult. SPNs can be metastatic. Hepatic and lymph node localizations are the most reported in the literature. The recurrence rate after surgical resection is 3-9%. We report the case of a 36-year-old patient who was complaining of abdominal pain for 2 months. An abdominal contrast-enhanced Computed Tomography (CT) scan showed a solido-cystic mass of the tail of the pancreas. The patient underwent laparoscopic radical antegrade modular pancreatosplenectomy. The diagnosis of SPN with lymph node metastasis was confirmed by histopathology and immunohistochemistry, requiring adjuvant chemotherapy.

Cancer patients are frequently treated by physical therapists. Chemotherapy, radiation, and surgery are examples of cancer treatments that are always improving and thereby increasing patient survival with each new cancer diagnosis. More specifically, with each cancer diagnosis, 5-year survival rates rise. Muscle weakness, lung dysfunction, weariness, and discomfort are all issues that cancer patients face. Finally, cancer patients’ activities of daily living (ADL) and quality of life tend to deteriorate (QOL). The inclement of increased breast and ovarian cancer in females are leading year by year. The psychological consequences of breast and ovarian cancer on women, as well as the psychosocial elements that may influence the cancer’s disease process and psychophysical result. The female cancer patients frequently experience worsening disease, sadness, and worry. Physical therapy can help patients regain strength and physical function, as well as enhance their quality of life and daily living independence, which may have been lost as a result of cancer or its treatment. Physical therapy may become increasingly important in the treatment of female cancer patients in the future.
Investigating Daptomycin-Membrane Interactions Using Native MS and Fast Photochemical Oxidation of Peptides in Nanodiscs
Authors: Reid Deseree , Dash Tapasyatanu , Wang Zhihan , Aspinwall Craig , Marty Michael
Published: February 2023

Daptomycin is a cyclic lipopeptide antibiotic that targets the lipid membrane of Gram-positive bacteria. Membrane fluidity and charge can affect daptomycin activity, but its mechanisms are poorly understood because it is challenging to study daptomycin interactions within lipid bilayers. Here, we combined native mass spectrometry (MS) and fast photochemical oxidation of peptides (FPOP) to study daptomycin-membrane interactions with different lipid bilayer nanodiscs. Native MS suggests that daptomycin incorporates randomly and does not prefer any specific oligomeric states when integrated into bilayers. FPOP reveals significant protection in most bilayer environments. Combining the native MS and FPOP results, we observed that stronger membrane interactions are formed with more rigid membranes, and pore formation may occur in more fluid membranes to expose daptomycin to FPOP oxidation. Electrophysiology measurements further sup-ported the observation of polydisperse pore complexes from the mass spectrometry data. Together, these results demonstrate the complementarity of native MS, FPOP, and membrane conductance experiments to shed light on how antibiotic peptides interact with and within lipid membranes.
Geometry Optimization: A Comparison of Different Open-Source Geometry Optimizers

Published: February 2023

Based on a series of energy minimizations with starting structures obtained from the Baker test set of 30 organic molecules, a comparison is made between various open source geometry optimization codes that are interfaced with the open-source QUantum Interaction Computational Kernel (QUICK) program for gradient and energy calculations. The findings demonstrate how the choice of the coordinate system influences the optimization process to reach an equilibrium structure. With fewer steps, internal coordinates outperform Cartesian coordinates while the choice of the initial Hessian and Hessian update method in quasi-Newton approaches made by different optimization algorithms also contributes to the rate of convergence. Overall, DL-FIND, geomeTRIC and ASE, using Hartree--Fock theory with the 6-31G** basis set, needed a comparable number of geometry optimization steps to the approach of Baker using a unit matrix as the initial Hessian to reach the optimized geometry. Due to its performance and the fact that DL-FIND is feature rich we use itas the default optimizer for QUICK.
