Serum activin-A as a predictive marker for postacne scarring
Authors: Abdel-Bary Ahmed , Tayae Eman , Magdy Basma , Hussein Tarek
Published: January 2023

Background

Postacne scar is the most distressing sequelae of inflammatory acne vulgaris. It develops owing to abnormal wound healing process in response to inflammation. Activins are members of the family named transforming growth factors-b that are involved in inflammation, immunity, and wound healing.

Objective

To evaluate human activin-A as a predictive marker for postacne scarring and the effect of treatment with oral isotretinoin on its serum level.

Patients and methods

A total of 40 patients who presented with either moderate or severe acne vulgaris were selected for this case–control study. Patients were classified into two groups: group A had no scarring and group B had postacne scarring. Group B patients were treated with oral isotretinoin therapy. Measurement of serum activin-A levels was done using the enzyme-linked immunosorbent assay technique.

Results

The mean serum level of human activin-A was significantly higher in patients with postacne scarring (189.47±59.63 ng/ml) than patients without scarring (155.4±41.19 ng/ml). Moreover, the mean serum level of human activin-A in group B was significantly decreased after treatment with oral isotretinoin. Patients with serum human activin-A level of more than 144.8 ng/ml are more liable to develop postacne scarring with 80.0% sensitivity and 55% specificity.

Conclusion

Serum level of activin-A could be a good and reliable marker for the prediction of those patients liable to develop postacne scarring, but more in-depth studies are still required to detect the exact pathogenic action of activin-A in the development of acne scars and to test the targeting of activin-A in an attempt to prevent postacne scarring.
Deep Reinforcement Learning for Intelligent Reflecting Surface-assisted D2D Communications
Authors: Nguyen Khoi Khac , Masaracchia Antonino , Yin Cheng
Published: January 2023

In this paper, we propose a deep reinforcement learning (DRL) approach for solving the optimisation problem of the network’s sum-rate in device-to-device (D2D) communications supported by an intelligent reflecting surface (IRS). The IRS is deployed to mitigate the interference and enhance the signal between the D2D transmitter and the associated D2D receiver. Our objective is to jointly optimise the transmit power at the D2D transmitter and the phase shift matrix at the IRS to maximise the network sum-rate. We formulate a Markov decision process and then propose the proximal policy optimisation for solving the maximisation game. Simulation results show impressive performance in terms of the achievable rate and processing time.
The Role of English in the Shaping of Polish Marketing Discourse
Authors: Smoleń-Wawrzusiszyn Magdalena
Published: January 2023

The aim of this article is to show the influence of academic and professional marketing English on Polish marketing discourse. In view of Poland’s transformative role in communist Europe, the paper can be regarded as a pilot study for the discussion of the phenomenon addressed in the context of the experience of other post-socialist nations. The analysis of the adaptation of English borrowings was based on numerous documents, participant observations and interviews. Critical Discourse Analysis with qualitative methods was the main methodological approach. The study shows that Polish marketing discourse is a linguistic-cognitive hybrid of Western and Polish cultures. For this hybrid, English has become both a trigger and a marker, as well as a carrier of the power of Western marketing ideology. Terminological borrowings from English were much needed, but in many situations there were conceptual or linguistic problems with their adaptation.
The Role of English Literature in Teaching Englishes: Moving Towards Educating Transcultural Communicators
Authors: Dunková Jiřina , Quinn Novotná Veronika
Published: January 2023

With the globalization of English, multilingual speakers of other languages have started to influence it linguistically and culturally, potentially challenging its established norms and standards. This paper first addresses terminological issues related to the area of Global Englishes and English as a lingua franca, then upon reviewing curricular documents relevant to the Czech educational context it summarizes findings from a pilot study conducted at local academically oriented high schools, which reveal that the English teachers still seem to associate “English” literature with inner circle creative production. Intending to bridge the gap between theory and practice, we designed and piloted several lesson plans taking heed of a broader conception of the anglophone literary canon inclusive of works from across all Kachruvian circles. We postulate that extended exposure to such literary creativity may help raise a generation of transcultural communicators, i.e., language users who thrive in dynamic language interactions across cultures.
Portraying the Male Abuser in Contemporary Women’s Fiction
Authors: Al Thobaiti Fatmah
Published: January 2023

Newspaper headlines show that awareness of intimate partner violence is a complicated issue that needs further examination. Works of fiction narrated by women trapped in abusive relationships are useful sites for the exploration of what intimate partner violence usually includes, and the identification of subtle behaviours that can be defined as violent and abusive but usually go unnoticed. This article submits two contemporary works of fiction, First Love and the Fifty Shades series, for a study of the covert mechanisms of emotional abuse. To understand such mechanisms, the article engages with feminist as well as postfeminist contemporary thinking on intimate partner violence. The analysis shifts the focus back to the male abuser by carefully depicting how he uses under-recognized, gendered forms of power to abuse his partner. The aim is to elucidate the capacity of first-person narratives to allow access to the abused woman’s mind, while simultaneously provoking questions about the abusers’ behaviours, making them a more powerful tool for understanding intimate partner violence than a newspaper report.
Liminal Femininity: Magical Realism and the Abject in Louise Erdrich’s Tracks
Authors: Mrak Anja
Published: January 2023

The article examines the liminal nature of the two central female characters in Louise Erdrich’s novel Tracks. Despite appearing as opposites, Fleur and Pauline, members of the Chippewa tribe, are both portrayed as socially abject and victims of the inexorable social transformation brought about by American imperialism to establish patriarchy and capitalism. Enhanced through magical realism, their animality and monstrosity call attention to a liminal femininity trapped in a social order that seeks to subjugate it. The novel also considers female sexual agency and different modes of exerting and losing control in encounters defined by sexual objectification and the male gaze. Fleur’s and Pauline’s stories demonstrate how the female body becomes a site of colonial enterprise, which devalues, exploits, and nearly eradicates the Native American community, their culture, and philosophies.

Published: January 2023

The concept of community of practice in the context of a selected group of speakers of a Fala de Xálima

The purpose of this paper is to study the current sociolinguistic situation of the language community of Xálima through the prism of the theory of community of practice. We define the community of practice as an aggregate of people who come together around mutual engagement in an endeavour of preserving and promoting their vernacular language. The empirical material will be a series of anthropological observations and comments on the semi-directed interviews, made in situ by the authors, in which we will analyse the efforts towards the orthographic standardization and their possible effects. We aim to demonstrate that the methodological principle of community of practice is applicable and suitable to shed new light over sociolinguistic minorized contexts, especially when conducting research in the field of the so-called third wave of sociolinguistics.
Semejanzas y contrastes en los sistemas de puntuación y en el uso de la coma en las oraciones subordinadas sustantivas y de relativo en español y polaco
Authors: Pawlak Aneta
Published: January 2023

Similarities and contrasts in punctuation systems and in the use of commas in subordinate nouns and relative clauses in Spanish and Polish

The objective of the article is twofold. On the one hand, it aims to briefly compare the definitions of punctuation marks in Spanish and Polish, to justify their syntactic-logical function from a diachronic point of view, and to compare the graphic representations of punctuation marks in both languages. On the other hand, it attempts to compare, in more detail, the use of the comma in subordinate substantive clauses and in relative clauses in both languages, starting from the Spanish syntax and based on the corpus from literary works. The conclusion shows that, between both languages, there are more similarities when it comes to defining punctuation marks than when comparing the use of commas in specific syntactic structures.
Hallucinating curls and a man-coffin. Occultist traces in Central European Surrealism
Authors: Kornhauser Jakub
Published: January 2023

The aim of the article is to analyse the influence of occultism on the development of the Central European avant-garde, especially the Surrealism of the ‘30s and ‘40s. On the one hand, occultists affirm a retreat from the tyranny of reason, which for many avant-garde artists embodies the pettiness of human existence, stifled by the forces of family and public duties. On the other hand, they are an inexhaustible source of props, actions and rituals. Both aspects are extremely important for both Czech Artificialists (Toyen and Štyrský) and Surrealists (Teige, Nezval); however, they gain particular importance in the theories and practice of Romanian Surrealists – Victor Brauner, Gherasim Luca and, above all, Gellu Naum. The space in which these transformed entities with a new status enter consciousness are the eponymous „dangerous territory” that André Breton wrote about, and which become a metaphor (but is it only a metaphor?) of the alliance of the proto-language and the proto-image.

L’idéal corrompu et l’idéal retrouvé. La fonction de la métaphore dans le Donet baillié au roy Loÿs douzieme de Jean Molinet
Authors: Gęsicka Anna
Published: January 2023

The corrupted ideal and the rediscovered ideal. The function of metaphor in Donet baillié au roy Loÿs twelfth by Jean Molinet

The subject matter of the analysis is an interesting poem by Jean Molinet. This paper focuses on the aspect of a certain nostalgia for the ideal which aims at both the semantic and poetic aspects of the poem. The existential ideal ‒ conceived from a spiritual perspective – is transmitted through a refined metaphorical system, conveying complex ideas and equivocal meanings, and covers two eponymous aspects, one of which turns out to be denied by the second. From an eschatological perspective, the author demonstrates how insignificant the old “worldly” ideal and alleged intellectual ideal will be in the eyes of God at the moment of Judgment. The opposition within the same metaphor of the two antithetical ideals is a process accentuating a revalorization of the existential perspective of the poet.
Le spleen et l’idéal. Pour une relecture de la fin’amor dans le Tristan de Thomas d’Angleterre
Authors: Gorecka-Kalita Joanna
Published: January 2023

Spleen and ideal. The concept of the fin’amor in Thomas’ Tristan

The concept of fin’amor in Thomas’ Tristan is traditionally subject to two interpretations: either it is glorified as a religion, with lovers as its martyrs, or it is criticized within the framework of Christian principles. This paper proposes an alternative to such interpretative dichotomy: it attempts to prove that glorifying the fin’amor as an ideal does not mean idealizing the lovers. In fact, Thomas judges severely his characters not in the name of Christian religion but in the name of an entirely profane, yet highly spiritual ideal of courtly love. The lovers, although far from being its embodiment, still aspire and refer to it, suffering from their own imperfection. This tension is highlighted by the aesthetics of doubling characterizing Thomas’ writing.
American Media Coverage of the January 6, 2021 Events at the United States Capitol: A Glimpse into the Polarisation of the United States News Media
Authors: Ostafiński Witold
Published: January 2023

Amerykańskie relacje medialne z wydarzeń na Kapitolu z 6 stycznia 2021 roku. Polaryzacja mediów informacyjnych w Stanach Zjednoczonych

Celem artykułu jest ukazanie skrajnej polaryzacji politycznej mediów informacyjnych w Stanach Zjednoczonych przez pryzmat doniesień dotyczących szturmu na Kapitolu 6 stycznia 2021 roku. Analiza tekstów prasowych, liberalnych i konserwatywnych źródeł informacyjnych donoszących o tym ataku pozwoliła pokazać, że szturm na Kapitol był zarówno produktem samej polaryzacji mediów, jak i wydarzeniem, które przyspieszyło dalszą polaryzację mediów. Uzyskane wyniki badań ujawniają, że istnieje poważna rozbieżność w zakresie relacjonowania tego samego wydarzenia przez różne media, bazujące na odmiennych źródłach informacji. Artykuł pokazuje, że wydarzenia z 6 stycznia 2021 roku dostarczają środków poznawczych, za pomocą których można zrozumieć trwającą od dawna polaryzację ideologiczną amerykańskich źródeł medialnych.

This paper aims to examine the extreme political polarization of the United States news media through the lens of the reporting on the January 6, 2021 Capitol insurrection. Through a close reading of news articles reporting on this event from both liberal and conservative news sources, this paper argues that the insurrection was both the product of this media polarization, as well as an event which precipitated further polarization of these media sources. The results of this research demonstrate that there is indeed a major discrepancy in media coverage of this event between the two disparate sources of news. Overall, this paper demonstrates that the January 6, 2021 events provide a cognitive means by which one can best ascertain the long-standing ideological polarization of the American news media sources.

Published: January 2023

A wireless sensor network (WSN) is an environment monitoring network that collects and transmits data wirelessly to the base station. Due to their inability to be recharged or replaced, sensors face battery constraints. Considering how much energy is wasted by sensors in WSN, this is one of the most popular research topics in WSN. Protocols for improving energy efficiency have been developed to improve the network's energy dissipation and, ultimately, its lifetime. An energy-efficient and throughputenhancing clustering technique is presented in this paper, which is superior to existing protocols based on LEACH. A cluster head in LEACH elected from a cluster that includes nodes with small residual energy will lead to an early death of the network, which will adversely affect its efficiency. The proposed clustering technique, on the other hand, uses the remaining energy of the sensor to make the sensor a cluster head. The base station finds the shortest path between the cluster heads. Through this compound, power dissipation is reduced, which contributes to a longer network lifespan and higher throughput. According to simulations performed with the NS3 simulator, the proposed clustering technique achieves higher network lifetime and throughput compared to some recent clustering protocols, i.e. LEACH, BCE-LEACH, and MO-LEACH.

—Standard datasets in deep learning-basedimage classification usually provide two favorable conditions for design: preservation of visual homogeneity of each category and uniform distribution of sample images. These conditions are not assured in a dataset of plant images. Two different species of plants under the same genus look very similar and the number of collectible images has a large variation over species.Visual similarity, however, can be turned into advantage in hierarchical approach, by assigning two-fold labels of species and genus, in two phases ofrough classification of genera and fine classification of species. We propose a hierarchical classification in which the concatenation scheme is augmented with a channel attention which focuses on the sibling relation of species. We compared our method with flat classification and conventional hierarchical classification. The test was on a PlantNet-300K dataset 300k images, composed of 303 genera and 1081 species. In experimental results, the channel attention layers lead to stable discerningof the minute difference among visually similar species. The proposed hierarchical classification method outperforms both the flat classification and the conventional hierarchical classification.

Competitive anxiety is the greatest challenge for athletes, especially in games involving big competitions. This study aims to formulate athletes' anxiety based on their sports performance. Therefore, this study found three parameters influencing athletes' anxiety: heart rate, blood pressure and muscle tension. Hence, the data collection from three phases, namely before, during and after the competition, was recorded. The data were analyzed based on the anxiety index formulation to obtain the athletes' anxiety index rate. By comparing the reading pace of normal persons to the results of this data analysis, the researcher created a set of athlete anxiety indexes. For future research, an anxiety monitoring system prototype based on IoT technology will be created using coding from the athlete's anxiety index to ensure that the coach can notice the athlete's anxiety rate early. With this study, it is believed that future sports athlete performance in the country will be more consistent.

Research depicts that vehicular accident is inevitable, especially during long-distance driving journeys due to occurrence such as dehydration and discomfort owing to the inadequate or poor operating performance of car airconditioning systems which can result in loss of the driver’s attention on the road. However, the aforementioned research gap or problem needs to be addressed to ensure the efficient operation of the car air-conditioning system to avert vehicular accidents. Hence, the goal of this research is to utilize a microcontroller to automatically control the car airconditioning system to ensure enhanced operating performance. Moreover, the key merit of this research is to assist drivers by preventing them from losing attention on the road due to a phenomenon such as dehydration and discomfort, especially, during long-distance driving journeys, which can cause vehicular accidents. Besides, another imperative component of this research is to automatically control, thus closing the vehicle’s window louvre once the air conditioner is in operation or turned on to ensure efficient utilization of energy (fuel) of the vehicle and ensure that the ambience in the vehicle is pretty comfortable for the passengers on board. The automated power window system is comprehensively verified by the proteus software. Nonetheless, the results via the simulation depict that the automated power window circuit considered in this paper can effectively and automatically close the vehicle’s window louvre once the air conditioner is turned on.

This study aims to develop an eddy current testing (ECT) probe that generates eddy current signals when a coil is placed above copper101 metal testing with and without nonconductive coating and the presence of lift-off height, i.e., 0, 2.5, 5.0, 7.5, and 10.0 0.5 mm. Then, the metal test with a variety of thicknesses, i.e., 1.5, 3.0, and 5.0 0.5 mm, and with varies of surface defects, i.e., 10, 20, and 30  0.5 mm, engraved on the metal testing. The coil probe is a rodshaped solenoid coil designed with an iron core with 65 mm length, 5 mm area, and 200 N turns. It demonstrates how the rod-shaped solenoid coil may be used to detect various surface defects on copper101 (C101). The optimal frequencies for C101 are 7.850 MHz. In conclusion, the output voltage signals for larger surface defect sizes increase but decrease as the thickness becomes thicker. Furthermore, as the lift-off height increases, the output voltage for both coated and non-coated metal decreases accordingly. Therefore, besides comparing the output voltage for coated and non-coated metals, there are minor differences which shows that the ECT technique in this studyis capableto detect surface defects appropriately.

Published: January 2023

A phototrophic purple bacterium Allochromatium sp. strain GSKRLMBKU–01 was used in this study for the reduction of hexavalent chromium. This phototrophic bacterium was isolated from samples collected from the coastal area of Visakhapatnam, India. Both the cells (free (FC) and alginate entrapped immobilized (IC)) are used for the reduction of chromate. Among them, chromate reduction was increased using immobilized cells. Immobilized cells entrapped in sodium alginate reduced the chromate up to 33 ± 3.0 μM on the 8th day of incubation by Allochromatium sp., incubated in presence of light (2000 lx) under the strictly anaerobic conditions, while a chromate reduction up to 26 ± 0.20 μM was recorded by FC of Allochromatium sp. Chromate reduction can be recorded even up to the 20th day by both FC and IC. An incubation period of 8 days was found to be optimum for its growth and chromate reduction. The maximum growth in terms of dry cell weight (DCW) of FC is recorded up to 1.7 ± 0.20 g.L-1 and IC is 2.0 ± 0.30 g.L-1. The growth was recorded even on complete chromate reduction. The final pH of the FC was recorded at pH 8.5 ± 0.10, while the final pH of 8.6 ± 0.20 was recorded for the IC of Allochromatium sp. in the growth medium. The obtained results were mentioned in terms of mean and standard deviation which are statistically significant at P ≤ 0.001 level. The detoxification of chromium in the large-scale systems by employing a purple phototrophic bacteria Allochromatium sp., is proposed.

Introduction: Sporadic presentation of hydatidiform has been reported previously as 1 in 1000 pregnancies. In rare cases asymptomatic molar pregnancies can cause problems if not identified in early radiological investigations. The aim of this study is to evaluate the frequency of hydatidiform (molar pregnancy) presenting with associated symptoms, analysis of determinants and management in Sindh, Pakistan. Methodology: This is a cross sectional study, patients were divided into categories according to maternal age, gravida while Beta HCG values were reported along with radiological investigation reporting to confirm hydatidiform molar pregnancy. Statistical package of social science version 21 was used to analyze the data. Results: Total 51 patients were identified with hydatidiform molar pregnancy during study period of 12 months from more than 1000 full term reported pregnancies, indicating 5.1% prevalence of disorder. The diagnosis has been confirmed only 1 (1.9%) case of partial molar pregnancy while 50 (99.1%) were complete molar pregnancy cases, managed by suction evacuation method, risks factors of hydatidiform molar pregnancy with advanced maternal age, recurrent molar pregnancy and positive family history the odds ratio has indicated positive association between first two determinants with OR of 1.71 and 1.21 respectively. Conclusion: Overall recorded frequency of hydatidiform in our institute is 5.1% within 1 year. Advanced maternal age and previous history of molar pregnancies are risk factors of hydatidiform.

Thermophilic bacteria are a group of bacteria that adapt to environmental conditions with high temperatures, ranging from 45 ° - 90 ° C. as the ring of fire, Indonesia has many volcanic areas as the source of thermophilic bacteria, once is in Ijen Crater, East Java. Thermophilic bacteria have the potential to produce heat-resistant / thermostable enzymes such as polymerase. DNA polymerase is a key enzyme in amplification process of DNA fragment. The objective of this study was to found the novels thermophilic bacteria isolated from Ijen Crater which has potential to be the source of DNA polymerase production. This study was carried out by growing the bacterial strains on suitable media, followed with thermal screening (70-900C), isolating and identifying the morphological and molecular characteristics of the selected isolates. Total of 12 isolates have selected after thermal screening in 700C for, which were identified as positive and negative bacteria in gram staining assay. All the selected isolates found to have same colony color in white, but various types in shape, border, elevation, and border with. There were 4 isolates that selected after incubation in 900C for 30 minutes, which were isolate 1, 5, 9, and 11. The DNA genome of four selected isolates then amplified using universal primer (16S rDNA) and pol1 to detect the presence of gene encoding polymerase. The result indicated that isolate 1, 5, 9, 11 were able to be the candidate thermophilic bacteria to produce DNA polymerase.

Published: January 2023

Alzheimer disease (AD) diderita oleh 30-35 juta penderita di dunia dan diperkirakan akan meningkat hingga 400% dalam 30 tahun kedepan di Indonesia. Salah satu obat yang telah diterima untuk pengobatan AD diisolasi dari tanaman Galanthus nivalis berperan sebagai inhibitor acetylcholinesterase (AChe), galantamine, yang memiliki efek yang singkat. Penerimaan terhadap senyawa herbal semakin luas karena kebutuhan obat baru dengan efek samping lebih sedikit dibandingkan obat sintetis. Studi ini bertujuan untuk mengetahui potensi piperine (PIP), piperlongumine (PL), dan thymoquinone (TQ) yang berasal dari Cabe Jawa (Piper retrofractum), Sirih Hitam (Piper betle var. nigra), dan Jinten Hitam (Nigella sativa) sebagai obat AD. Struktur senyawa diperoleh dari PubChem, kemudian struktur 3D-nya dibangun menggunakan Chimera agar kompatibel untuk docking molekular dengan Autodock, PyRx, dan Biovia Discovery Visualization. Aktivitas biologi ketiganya diprediksi menggunakan PASS way2drug, sedangkan sifat fisikokimia dan farmakokinetiknya dengan Swiss ADME dan pkCSM. Berdasarkan prediksi sifat fisikokimia dan farmakokinetik, ketiga senyawa tersebut memenuhi syarat sebagai obat. Docking molekular menunjukkan bahwa ketiganya dapat berinteraksi dengan reseptor. Untuk interaksi dengan AChe, PIP paling baik, disusul dengan PL dan TQ. PL Untuk interaksi dengan butyrylcholinesterase (BChe), PL paling baik, disusul dengan PIP dan TQ. Walaupun nilai binding affinity TQ lebih rendah dibandingkan kedua senyawa lainnya, namun TQ lebih mudah menembus blood brain barrier (BBB) dan memiliki aktivitas biologi yang berpotensi aktif (nilai Pa > 0.7) terkait AD lebih banyak dibandingkan kedua senyawa lainnya. Dengan demikian, TQ berpotensi lebih tinggi untuk dipelajari lebih lanjut secara in vitro maupun in vivo untuk penanganan AD.
