Social priming: Exploring the effects of speaker race and ethnicity on perception of second language accents
Authors: McLaughlin Drew Jordan , Van Engen Kristin J.
Published: April 2022

Listeners use more than just acoustic information when processing speech. Social information, such as a speaker’s perceived race or ethnicity, can also affect the processing of the speech signal, in some cases facilitating perception (“social priming”). We aimed to replicate and extend this line of inquiry, examining effects of multiple social primes (i.e., a Middle Eastern, White, or East Asian face, or a control silhouette image) on the perception of Mandarin Chinese-accented English and Arabic-accented English. By including uncommon priming combinations (e.g., a Middle Eastern prime for a Mandarin accent), we aimed to test the specificity of social primes: For example, can a Middle Eastern face facilitate perception of both Arabic-accented English and Mandarin-accented English? Contrary to our predictions, our results indicated no facilitative social priming effects for either of the second language (L2) accents. Results for our examination of specificity were mixed. Trends in the data indicated that the combination of an East Asian prime with Arabic accent resulted in lower accuracy as compared to a White prime, but the combination of a Middle Eastern prime with Mandarin accent did not (and may have actually benefitted listeners to some degree). We conclude that the specificity of priming effects may depend on listeners’ level of familiarity with a given accent and/or racial/ethnic group, and that the mixed outcomes in the current work motivate further inquiries to determine whether social priming effects for L2-accented speech may be smaller than previously hypothesized and/or highly dependent on listener experience.

Published: April 2022

Objectives. There are, on average, three people who die daily from an asthma attack in the UK. Asthma self-management and good adherence can reduce this rate of mortality. Since adherence to preventative medication is important for many people with asthma, we investigated asthma patients' and non-patients’ perceptions about asthma, the similarities between themes in interviews and on Twitter and potential influence on adherence. Design. Both patients' and non-patients' perceptions about asthma were examined in a combination of interviews and content analysis of Twitter data.Methods. Fourteen semi-structured interviews were conducted and analysed using thematic analysis; A coding instrument was developed to capture perceptions on Twitter and a content analysis was conducted on 3.000 tweets. Convergence analysis identified similar topics between interviews and social media data analysis and where these were similar or different. Results. Several themes emerged from interviews, grouped as patients’ internal perceptions (about asthma) and external perceptions (what they considered were others’ perceptions). Qualitative analysis of Twitter content resulted in identification of several themes with negative humour and self-pity being the most prominent ones. Convergence analysis revealed mutual topics from tweets and interviews: self-pity, humour, disclosure, lack of understanding - topics that reflect stigmatization; attachment to inhaler and perceived sense of community.

Published: April 2022

This study sought to investigate the perceived influence of stressful events (i.e., the outbreak of the war in Ukraine, the political situation, and the COVID-19 pandemic) on the depressive symptoms and psycheache experienced by Polish adults. The study also aimed to explore the association between experiential avoidance and emotional distress. More than half of the participants reported experiencing a subjective increase in their depressive symptoms since the outbreak of the war in Ukraine. A larger percentage of participants associated their emotional distress with the outbreak of the war and the political situation than with the COVID-19 pandemic. In addition, experiential avoidance was found to be associated with subjective increases in the participants’ depressive symptoms and emotional distress.

In this article, we wish to present a new psychological method of analysis of the gender questions that has affected our world in the last centuries. We wish herein to analyse the question of gender relations through the lens of Jungian psychology and symbolic shift in human psychology effected through a fundamental change in the structure of the psychological human world. Through this method, we wish to analyse and decipher the psychological relations that have affected mankind most deeply since times immemorial, reach at a better understanding of human psychology and its structure at large, and perhaps a better of understanding of not only human civilisation at large but ourselves on an individual level as well.
POWER, EMERGENCE, AND THE MEANINGS OF RESISTANCE: OPEN ACCESS SCHOLARLY PUBLISHING IN CANADA
Authors: Price Taylor , Puddephatt Antony J
Published: April 2022

Open access publishing is an increasingly popular trend in the dissemination of academic work, allowing journals to print articles electronically and without the burden of subscription paywalls, enabling much wider access for audiences. Yet subscription-based journals remain the most dominant in the social sciences and humanities, and it is often a struggle for newer open access publications to compete, in terms of economic, cultural, and symbolic capital (Bourdieu, 2004). Our study explores the meanings of resistance held by the editors of open access journals in the social sciences and humanities in Canada, as well as the views of university librarians. To make sense of these meanings, we draw on Lonnie Athens’ (2015) radical interactionist account of power, and expand on this by incorporating George Herbert Mead’s (1932, 1938) theory of emergence, arguing that open access is characteristic of an “extended rationality” (Chang, 2004) for those involved. Drawing on our open-ended interview data, we find that open access is experienced as a form of resistance in at least four ways. These include resistance to (1) profit motives in academic publishing; (2) access barriers for audiences; (3) access barriers for contributors; and (4) traditional publishing conventions.
AN OVERVIEW OF THE LEGAL FRAMEWORK GOVERNING CYBERBULLYING AMONG CHILDREN IN MALAYSIA
Authors: Nurulhuda Ahmad Razali  , Nazli Ismail Nawang
Published: April 2022

The Internet has changed people’s lifestyles since its inception in the nineties. Since then, it has become an essential tool and daily need for all generations, including children. Despite its significant advantages for online class, gathering knowledge and information, it also has its disadvantages. One of the disadvantages is that children can be potentially exposed to cyberbullying, either as a victim or a perpetrator. Easier access to the Internet via various types of electronic devices such as smartphones, tablets, laptops, and desktop computers has contributed to the increase in child cyberbullying incidents. A survey conducted by the United Nations Children’s Fund (UNICEF) in 2019 discovered that 28% children in Malaysia were victims of online violence. In global statistics among 28 countries, Malaysia was ranked 6th place and 2nd place among the Asia countries in cyberbullying. The objectives of this study are to examine the scenario of child cyberbullying in Malaysia and identify related legal provisions that existed in Malaysia. The method used in this study is doctrinal research by referring to journals, books, conference papers, newspapers, and other periodicals. This research found out that the existing laws are not adequate to protect children from cyberbullying. Thus, it is suggested that there should be specific provisions on cyberbullying protection especially for child in Malaysia.

Published: April 2022

Migration occurs for a variety of reasons, including political, economic, social, and environmental considerations. Migrants frequently bring members of their families to receiving countries in search of a new and better life. Like many other countries, Malaysia has long struggled with the issue of undocumented migrants, including children. One of the most critical issues concerning migrant children is the deprivation of their right to an education. This issue is a serious concern because education is regarded as a fundamental human right that can realize and fulfil various other rights. This paper aims to investigate Malaysian law concerning the right of undocumented migrant children to an education. It adopts qualitative research of doctrinal and comparative nature. It will comparatively analyse the existing Malaysian legal framework on the right of undocumented migrant children to education in light of international human rights standards established by international instruments. The article also attempts to identify the barriers that undocumented migrant children experience when trying to obtain an education. The paper concludes that the current Malaysian legal framework is incomprehensive and inadequate to guarantee the right to education of undocumented migrant children. As such, the paper provides recommendations towards the improvement of the existing laws and policies on this particular issue of concern.

The article examines the process of vermicomposting of municipal organic waste. To determine the optimal composition of bio humus, various options and proportions of mixingorganic waste with soil are considered. In the course of the study, three different variations of organic waste were developed, mixed with manure: 1 — soil, paper, vegetables, fruits, wood waste, cow manure (1:0.5:1); 2 — soil, vegetables and fruits, wood waste (1:1); 3 — soil, cow manure (1:1). The results of the experiment showed that all substrates have high germination of tomato seeds. However, a mixture of soil, paper, vegetables,fruits, wood waste, cow manure increases the yield of tomatoes by 11 % compared to other experimental substrates. Vermicomposting E. was performed using E. fetida worms. This kind of worms is characterized by high yield. For vermic content, the moisture content must be at the level of 60 %. Bacteria also play an important role in vermicompost. With air humidity below 40 %, their activity decreases and stops at temperatures below 10 %.In this experiment, solid organic waste processing technology reduces the shortage of cheap organic fertilizers in the market and offers new opportunities for profit for small enterprises. The results obtained can be usedfor processing organic waste of the city on an industrial scale and applied as fertilizer in agriculture.

Currently, modern satellite systems are increasingly used in various areas of studying natural resources and the dynamics of natural phenomena, and in carrying out an ecological assessment of the state of the environment. At the same time, remote sensing data provide greater visibility, data acquisition in dynamics, high speed of image acquisition, and transmission. The article presents the results of spatio-temporal changes in the vegetation biomass of the Kokshetau National Park based on the calculation and analysis of the vegetation index. Based on the analysis of the NDVI values, the tendencies of changes in phytomass were estimated and correlations with the main climatic characteristics of the territory for the studied period were revealed. For the research, we used Landsat satellite images and geoinformation mapping in the ArcGIS software package. In general, there is a negative trend in the values of the indices for theforests of all functional zones over a 10-year period. For the preservation and further renewal of forests, the National Park of Kokshetau needs to carry out a number of regulatory measures.

Host genes act as a factor related to susceptibility and resistance to viral infections. The article provides a description of modern scientific studies devoted to the study of the role of the ACE2, TMPRSS2 genes, and their single-nucleotide polymorphisms in infection with the SARS-CoV-2virus. SNPs of the ACE2 gene, TMPRSS2 can affect the penetration of SARS-CoV-2 into the cell. In addition, the study of these polymor-phisms will determine the predisposition of an individual to the disease COVID–19, or the nature of its course. Based on the literature sources, the role of angiotensin-converting enzyme 2 and transmembrane proteases in the participation of the SARS-CoV-2 virus penetration process with the body cells is noted. Other functions that ACE2 and TMPRSS2 receptors perform in the human body are also described. The characteristics of two genes and their fairly well-known polymorphisms are given. The tissues and organs in which genes are expressed are marked. Information on the frequency of alleles of genetic variants of genes in different populations is shown. In addition to describing the relationship of gene polymorphisms with the disease caused by SARS-CoV-2, information is provided on the association of these genetic variations with diseases of the blood vascular system and oncological diseases.

В Казахстане и во всем мире существует проблема утраты биоразнообразия растительных ресурсов. Поэтому ведутся работы по созданию криогенных банков, в которых проводится длительное хранение гермоплазмы растений при сверхнизкой температуре –196 °С. Для семян, сохраняемых в криогенных банках, требуется изучение их состояния покоя и действия веществ, которые могли бы стимулировать их всхожесть. Важными объектами для исследования являются лекарственные растения, так как в Рес-публике отсутствует отлаженная система промышленного выращивания лекарственных растений и производства фармацевтических препаратов на основе местного сырья. Поэтому требуется научная информация о долгосрочном сохранении жизнеспособного семенного материала и способах стимуляции проращивания семян. В результате проведенных экспериментов выявлено положительное влияние гибберелловой кислоты (ГК) и жидкого азота (ЖА) на увеличение процента энергии прорастания (ЭП) и лабораторной всхожести (ЛВ) семян лекарственных растений. В среднем,после воздействия ЖА на семена, увеличивался процент ЭП в 1,4 и ЛВ в 1,5 раза. После воздействия на семена ГК процент ЭП увеличивался в 1,2 раза, а ЛВ — в 2,9 раза. Выявлено, что для стимуляции ЭП и ЛВ достаточно обработки семян одним из способов, ГК или ЖА. Установлено, что семена расторопши пятнистой теряют всхожесть после хранения при температуре 1±1 °С в течение 9 месяцев. Возможно, для стимуляции ЭП и ЛВ требуется обработка химическими реагентами свежесобранных семян. Отмечена эффективность воздействия ЖА на ЭП в культуре in vitro семян валерианы лекарственной и ромашки аптечной сорт «Карагандинская» в 4,5 и в 1,8 раза соответственно. Процент ЛВ валерианы лекарственной после воздействия ЖА возрос в 1,3 раза, при этом не было отмечено влияния ЖАна ЛВ семян ромашки аптечной сорт «Карагандинская».

This article is devoted to the study of the effect of macroparticles and nanoparticles of zinc and zinc oxide on animals. The toxicity of pollutants to the fauna of aquatic ecosystems was assessed in course of a laboratory experiment. The test objects, the larvae of crustaceans of Artemia salina, were exposed to the particles of zinc (Zn) and zinc oxide (ZnO). The particle content in the water was 5 mg, 10 mg, 20 mg per 100 ml. The obtained results of the research indicate that the zinc and zinc oxide nanoparticles in the studied concentrations show a slight degree of toxicity during the 48-hour experiment period. The macroparticles of these substances have higher toxic properties for eggs and larvae of Artemia salina.
Editorial Introduction
Authors: Schweitzer Reinhard , Humphris Rachel , Monforte Pierre
Published: April 2022

This article introduces the theme and scope of this Special Themed Section on the role of ‘voluntariness’ in the governance of migration. It provides an overarching framework for defining and operationalising the notion of voluntariness in the field of migration studies; and for investigating how voluntariness works across different sites, situations and in distinct national contexts. We understand voluntariness as a general principle and instrument that (re)produces the active participation of different actors across society in the (state-driven) management of migration. This focus leads us to explore key dimensions in the shifting (neo-liberal) governmentality of migration in contemporary societies. The introduction makes the case for bringing together seemingly disparate examples and case studies in order to shed new light on how certain ascribed meanings and understandings of voluntariness can shape the actions of very different subjects involved in contemporary bordering processes.

Published: April 2022

This article draws on our experiences of carrying out PhD research on migration during the COVID-19 pandemic. We are all involved with the University College London Migration Research Unit (MRU), and our PhD research explores the lived experiences of migrants and people affected by migration. This is the first of two articles in this issue of Migration and Society addressing the implications of COVID-19 on migration research from the perspective of postgraduate researchers. In this article, we firstly reflect on how “crises,” including the COVID-19 pandemic, inevitably shape contexts of migration research. We then share how COVID-19 has shaped our relationship to “the field” and our formal research institutions. Finally, we share how we have adapted our methodologies in response to COVID-19 and, considering the complex ethical and practical challenges posed by this context, reflect on what it means to make methodological “adaptations” in times of overlapping crises.

Scorodocarpus borneensis Becc is an ancient tree in Borneo island, that produces a unique odor like garlic. Thus, it is utilized to enhance food flavor by the locals. This study investigated phytochemical compounds, antioxidant activity, and toxicity of the S. borneensis leaves fractions. The fractions were prepared using several gradient elutions in the sequence: n-hexane, ethyl acetate, ethanol, methanol, and 70% methanol. Phytochemicals were observed qualitatively toward the presence of phenol, alkaloid, tannin, flavonoid, and terpenoid; quantitatively conducted toward phenolic, flavonoid, and alkaloid contents. DPPH free radical scavenging activity method was conducted to identify the antioxidant activity. The BSLT Test determined the toxicity. The result revealed that all the leaves' fractions showed the absence of terpenoids. The rest of the phytochemicals screened positively in all fractions. The ethyl acetate fraction owned the most prominent phenolic, alkaloid, and flavonoid content (614.86 ± 35.82 mg GAE/g, 462.25 ± 5.12 mg BE/g 271.67 ± 1.30 mg QE/g of extracts, respectively). The antioxidant activity (IC50 value) varied from 100.24 ± 19.69 to 237.89 ± 2.66 μg/mL. All fractions obtained were classified as non-toxic, except methanol fraction showed low toxicity against nauplii of Artemia salina L.

Sida rhombifolia or sidaguri, was taken from two regions in East Java Province, Indonesia, namely Batu (SB) and Ngawi (SN), was investigated in this study. The two samples were determined the content of secondary metabolites by using LC-MS/MS. They were also evaluated for their phytochemical content, total phenolic content (TPC), and antioxidants activity, using the DPPH and ABTS methods. The highest TPC (126.93 ± 0.63 mg GAE / g) was observed in the ethyl acetate fraction of SN. The antioxidant activity against DPPH and ABTS from crude extracts and fractions showed that SB was more potent than SN, although the values were both less active. A total of 54 secondary metabolites were identified by the LC-MS-MS method from both species, with SB samples producing more secondary metabolites (48 compounds) than SN (37 compounds). These compounds are included in lipids, alkaloids, ester lactones, benzoic acid derivatives, steroids, carboxylic acid derivatives, flavonoids, and phenyl propanoic.

A simple and efficient one-pot three-component microwave assisted syntheses of 3,4-dihydropyrimidin-2(1H)- ones/thione derivatives were carried out by condensation of ethylacetoacetate/ methylacetoacetate, aromatic aldehydes and urea/thiourea by using silica ferric hydrogen sulfate as a reusable catalyst.It has been observed that a small amount of SFHS (5 mol%) is sufficient to bring out the synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones. Structurally diversed aromatic aldehyde bearing electron donating, withdrawing groups and hetero-atom were reacted smoothly used under the same reaction condition.High yields, shorter reaction times, one pot condensation, operational simplicity, easy work-up, and purification of products by non-chromatographic methods are some additional features of this method.Furthermore, the catalyst can be recovered and reused five times without any significant loss of activity.

Published: April 2022

Potassium-magnesium ores of the Chelkar deposit in Kazakhstan have a complex mineralogical composition and contain soluble sodium salts, which are an impurity component in the processing of ore into potassium fertilizers. In this regard, enrichment of natural potassium salt by incomplete dissolution was studied. Based on the experimental results the optimal washing mode was determined which ensures maximum removal of sodium salts from the natural salt composition and minimal losses of potassium salts with washing water. Mathematical models of the process under study were obtained through statistical processing of the experimental data. The results have shown that statistically, reliable regression equations are ones that describe potassium and sodium content in the solid phase relative to the process duration and water consumption for washing. The models can be used to operate the potassium ore enrichment process and to predict dependencies under various process conditions. 3D visual analysis of the process using regression surfaces for all significant equations has revealed the relationship between potassium ore enrichment indicators and process parameters.

This study aims to conduct the synthesis and characterization of nanohybrid multilayer ZnO-SiO2/Chitosan (NHMZnO-SiO2/Chitosan) using SEM and TEM to show the rod-shape morphology. Furthermore, the compound is used as a textile fiber coating material for anti-bacterial and UV-protected applications. The process was followed by hydrophobization of Dodecyltrietoxysilane (DTS) using a 1,2,3,4-butane tetracarboxylic acid (BTCA) crosslinker. FT-IR showed that the coating of NHM-ZnO-SiO2/Chitosan on textile fibers has covalent ester interactions with the appearance of the C=O stretching functional group at ~1700 cm-1 and each cotton fabric provided different intensity. Meanwhile, SEM showed that the layer has a rough surface, which is associated with the distribution of NHM-ZnOSiO2/Chitosan to create a hydrophobic surface, as evidenced by the water contact angle WCA = 100-119o. Furthermore, UV-DRS analysis was also conducted for UV protection testing and a decrease in the value of Eg = 2.87 eV on textiles coated with NHM-ZnO-SiO2/Chitosan and DTS was obtained. Anti-bacterial activity of uncoated, BTCA - ZnO-SiO2/Chitosan coating, BTCA - ZnO-SiO2/Chitosan coating, and DTS textiles were evaluated against bacterial cells of Staphylococcus epidermidis (37.7 - 47.2) mm and Pseudomonas aeruginosa (42.0 - 49.2) mm.

ZSM-5 was enriched with NiO (nickel oxide) or MoO3 (molybdenum oxide) and used as a catalyst to increase selectivity towards the bio-jet fuel fraction from the hydrocracking of coconut oil. NiO and MoO3 were incorporated into ZSM-5 through wet impregnation at various concentrations of 0.5–5% (wt.). The catalyst material characteristics were analyzed using XRD (X-ray Diffraction), TEM (Transmission Electron Microscope), and nitrogen gas adsorption instruments. The catalyst activity was observed through a hydrocracking reaction at a temperature of 475 °C for 3 hours, using coconut oil as feed and the catalyst concentration was 2 (wt.%). The results showed that NiO and MoO3 were distributed successfully into ZSM-5. Catalyst's catalytic activity was strongly influenced by the amount of NiO and MoO3 embedded into ZSM-5. The Ni-1, Ni-5, Mo-1, Mo-3, Mo-4, and Mo-5 catalysts increased the selectivity towards the bio-jet fraction by 55%, 34%, 49%, 37%, 36%, and 62%, respectively when compared to ZSM-5.

Peels, seeds, liquids, and molasses are among the waste products produced by the fruit and vegetable processing industries. These waste products are rich in carbohydrates, proteins, fibers, vitamins, and minerals. Fermentation can be used to produce colors from this waste. Our trash disposal concerns are solved and pollution in the environment is reduced by reusing these materials. Solid-state fermentation of Blakeslea transport (+) MTCC 884 was used. Orange, carrot, and papaya peel waste can be used to mine and optimize environmental elements for the formation of carotene. All factors had a significant impact on -carotene production, with a determined yield of 0.125-0.128 mg/mL. A variety of techniques were used to characterize the extracted color, including High-Pressure Liquid Chromatography (HPLC), LC-MS, mass spectroscopy, and FTIR. (Rt 13.37) was confirmed by mass spectroscopy of the extracted color, which yielded 537.608 as the mass/charge ratio (m/z). A further 76 percent of these fruits and vegetable wastes contained -carotene, suggesting that they could be used to produce pure carotene. DPPH and ABTS tests indicate that it has good antioxidant capabilities. Keywords: Fruit Peel Waste, Fermentation, HPLC, FTIR, UV-V

A potent antiepileptic drug was developed by synthesizing a set of novel thiazoles substituted oxazole derivatives using multi-step synthesis. FT-IR, 1H-NMR, Mass spectroscopy, and elemental analyses are employed to confirm the structure of compounds. Molinspiration online tool was used to predict the molecular properties and molecular docking was employed to predict the antiepileptic potency of the title analogs. MES and scPTZ tests were employed to determine the antiepileptic potency of thirteen prepared novel thiazole substituted oxazole derivatives. In addition, the neurotoxicity of the compounds was also estimated using the rotarod test. Entire tested derivatives displayed varying degrees of antiepileptic and neurotoxicity potency. The pharmacological potency of prepared derivatives was compared with their chemical structures. Among fifteen tested title compounds the potent compound of this series was found to be 4-(4-(2-(4-chlorobenzylideneamino)thiazol-4-yl)benzylidene)-2-methyloxazol-5(4H)-one BTBO3 which may act as a lead molecule to find potent and safer antiepileptic drug

Authors: Kasemsuwan J. , Sabau S.V. , Somboon U.
Published: April 2022

The purpose of this research is to present the steps of one-dimensional differential transformation method (DTM) to find the series solutions for the vibrations of a circular membrane under the specified initial and boundary conditions. The problems will be studied in the both cases of vibrations depending only on radius and of the vibrations depending on both radius and angle. We illustrate four examples of problems which the exact solutions can be solve analytically and compare them to the DTM results, to show that the DTM is reliable and of high accuracy. This work shows that the DTM is easier to use than the analytical method from the point of view of programming.

Published: April 2022

BACKGROUND: Not much is known about developmental motor disorders in the first year of life of children diagnosed with idiopathic scoliosis (IS). OBJECTIVE: This study aimed to compare the occurrence of asymmetry or muscle tone disorders in the first year of life in adolescents with IS and their healthy counterparts. METHODS: The parents of adolescents with IS and without scoliosis completed a survey on the occurrence of asymmetry, abnormal muscle tone, and physiotherapy in their children in the first year of life. Pearson’s chi square test and Cramer’s coefficient were used. RESULTS: The final analysis included 527 surveys completed by parents of adolescents with idiopathic scoliosis (150) and without scoliosis (377). A significantly higher frequency of asymmetry (p= 0.001) and muscle tone disorders (p= 0.001) was noted in adolescents with idiopathic scoliosis. The results also revealed a significant association between scoliosis and asymmetry (p= 0.001), as well as muscle tone (p= 0.001). CONCLUSIONS: Developmental asymmetry or improper muscle tone in the first year of life could be considered a potential factor in the development of scoliosis; however, this hypothesis should be confirmed in future studies. Infants diagnosed with developmental disorders require systematic observation.
lncRNA ELFN1-AS1 predicts poor prognosis and promotes tumor progression of non-small cell lung cancer by sponging miR-497
Authors: Yang Bin , Miao Shuai
Published: April 2022

BACKGROUND: More novel biomarkers need to be discovered to improve the therapeutic efficiency of non-small cell lung cancer (NSCLC). lncRNA ELFN1-AS1 (ELFN1-AS1) was proved to play crucial roles in numerous diseases, its intention in NSCLC remains unclear. OBJECTIVE: This study aimed to investigate the function of ELFN1-AS1 and its potential mechanism in NSCLC development. METHODS: A total of 117 NSCLC patients were recruited and provided paired NSCLC tissues and normal tissues. The expression of ELFN1-AS1 was analyzed by PCR. The biological function of ELFN1-AS1 was estimated by CCK8 and Transwell assay. Additionally, the potential mechanism underlying the function of ELFN1-AS1 was explored by the dual-luciferase reporter assay and western blotting. RESULTS: The significant upregulation of ELFN1-AS1 was found in NSCLC tissues and cells, which was closely associated with the TNM stage, lymph node metastasis status, and overall survival of patients. The knockdown of ELFN1-AS1 was found to inhibit the cellular processes and EMT of NSCLC. Moreover, ELFN1-AS1 was found to serve as a sponge to binding with miR-497, and CCNE1 was demonstrated to be the downstream target of miR-497, which was speculated as the potential mechanism underlying the function of ELFN1-AS1. CONCLUSIONS: ELFN1-AS1 acts as an independent prognostic biomarker and tumor promoter of NSCLC by sponging miR-497/CCNE1 axis.

Published: April 2022

Background: Information on prevalence, pathophysiology, and clinical assessment of paratonia are scarce. In a previous study, we suggested that surface electromyography (EMG) can be used to assess paratonia. Objective: To assess clinical and EMG features of paratonia in both patients with cognitive impairment and healthy subjects. Methods: We examined 18 patients with Alzheimer’s disease (AD), 21 patients with mild cognitive impairment (MCI), 30 healthy seniors (seniors), and 30 healthy juniors (juniors). Paratonia was assessed using the “Paratonia Scale”. EMG bursts were recorded from biceps and triceps during manually applied passive movements of elbow joint. Continuous (sinusoidal) and discontinuous (linear) movements were applied at 2 different velocities (fast and slow). Results: In comparison to juniors, seniors had higher clinical scores. In comparison to seniors, AD had higher oppositional scores, while MCI had higher facilitatory scores. EMG activity during passive movements correlated with paratonia clinical scores, was velocity-dependent and increased with movement repetition, most effectively for sinusoidal movements. Similar EMG activity was detected in not paratonic muscles. Conclusion: Paratonia increases with normal aging and cognitive decline progression. While facilitatory paratonia is due to involuntary contraction of the shortening muscle, oppositional paratonia is due, at least partially, to involuntary contraction of the lengthening muscle. Most characteristic feature of this muscle contraction is the progressive increase with movement repetition, that helps distinguish oppositional paratonia from spasticity and rigidity. A similar EMG activity is detected in not paratonic muscles, showing that, during tone assessment, the descending motor system is incompletely inactivated also in normotonic muscles.
