Efficacy of single dose of phenytoin/fosphenytoin in benign convulsions with mild gastroenteritis
Authors: Lee Keun Soo , Lee Bo Lyun
Published: March 2023

Background. This study evaluated the efficacy of a single dose of phenytoin/fosphenytoin (PHT) to control repetitive seizures in children with benign convulsions with mild gastroenteritis (CwG).
Methods. Children aged between 3 months and 5 years with CwG were retrospectively enrolled. Convulsions with mild gastroenteritis were defined as (a) seizures with acute gastroenteritis without fever or dehydration; (b) normal blood laboratory results; and (c) normal electroencephalography and brain imaging findings. Patients were divided into two groups according to whether or not intravenous PHT (10 mg/kg of phenytoin or phenytoin equivalents) was administered. Clinical manifestations and treatment efficacy were evaluated and compared.
Results. Ten of 41 children eligible for inclusion received PHT. Compared to children in the non-PHT group, those in the PHT group had a higher number of seizures (5.2 ± 2.3 vs. 1.6 ± 1.0, P < 0.001) and a lower serum sodium level (133.5 ± 3.2 mmol/L vs. 137.2 ± 2.6 mmol/L, P = 0.001). Initial serum sodium levels were negatively correlated with seizure frequency (r = -0.438, P = 0.004). In all patients, seizures were completely resolved with a single dose of PHT. There were no significant adverse effects from PHT.
Conclusions. A single dose of PHT can effectively treat CwG with repetitive seizures. The serum sodium channel may play a role in seizure severity.

Authors: Kılıç Mehmet , Özcan Mehmet Hazar , Taşkın Erdal , Şen Aşkın
Published: March 2023

Background. Chronic mucocutaneous candidiasis (CMC) is characterized by recurrent or persistent infections of the skin, nail, oral, and genital mucosa with Candida species, mainly Candida albicans. In a single patient, the first genetic etiology of isolated CMC autosomal recessive interleukin-17 receptor A (IL-17RA) deficiency was reported in 2011.
Case. We report four patients with CMC who displayed autosomal recessive IL-17RA deficiency. The patients were from the same family, and their ages were 11, 13, 36, and 37 years. They all had their first CMC episode by six months of age. All patients manifested staphylococcal skin disease. We documented high IgG levels in the patients. In addition, we found the coexistence of hiatal hernia, hyperthyroidism, and asthma in our patients.
Conclusions. Recent studies have provided new information on the heredity, clinical course, and prognosis of IL-17RA deficiency. However, further studies are needed to reveal the full picture of this congenital disorder.

Published: March 2023

Background. Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a peripheral nervous system disease associated with polyautoimmunity.
Case. We report a previously healthy 13-year old boy who was referred to our outpatient clinic with gait disturbance and distal lower limb weakness that had been increasing for six months. The patient had decreased deep tendon reflexes in the upper extremities and absence in the lower extremities, reduced muscle strength in the distal and proximal lower extremities, muscle atrophy, drop foot, and normal pinprick sensations. The patient was diagnosed with CIDP as a result of clinical findings and electrophysiological studies. Autoimmune diseases and infectious agents were investigated in terms of triggering CIDP. Although there was no clinical sign other than polyneuropathy, he was also diagnosed with Sjögren`s syndrome due to positive antinuclear antibodies and antibodies against Ro52, and with autoimmune sialadenitis. After six months of monthly intravenous immunoglobulin and oral methylprednisolone treatments, the patient was able to dorsiflex his left foot and walk without support.
Conclusions. To our knowledge, our case is the first pediatric case with the coexistence of Sjögren`s syndrome and CIDP. Therefore, we suggest investigating children with CIDP in terms of underlying autoimmune diseases such as Sjögren`s syndrome.

Background. Osteosarcoma is the most common type of primary malignant bone tumor in the extremities. The main purpose of this study was to determine clinical features, prognostic factors, and treatment results of patients with osteosarcoma at our center.
Methods. We retrospectively analyzed the medical records of children with osteosarcoma between the years 1994-2020.
Results. 79 patients were identified (54.4% male, 45.6% female). The most common primary site was the femur (62%). Twenty-six of them (32.9%) had lung metastasis at diagnosis. The patients were treated between 1995- 2013 according to the Mayo Pilot II Study protocol, while the others were treated with the EURAMOS protocol between the years 2013-2020. Sixty-nine patients underwent limb salvage surgery as a local treatment, whereas seven underwent amputation. The median follow-up time was 53 months (2.5-265 months). The event-free survival (EFS) and overall survival (OS) rates at 5 years were 52.1% and 61.5%. The 5-year EFS and OS rates were 69.4% and 80% in females; 37.1% and 45.5% in males (p=0.008/p=0.001). The 5-year EFS and OS rates of the patients without metastasis were 63.2% and 66.3%; with metastasis 28.8% and 51.8% (p=0.002/p=0.05). For good-responders, the 5-year EFS and OS rates were 80.2% and 89.1%; while for poor-responders, 35% and 46.7% (p=0.001). Mifamurtide was used in addition to chemotherapy as of the year 2016 (n=16). The 5-year EFS and OS rates were 78.8% and 91.7%, respectively for the mifamurtide group; 55.1% and 45.9%, respectively for the non-mifamurtide group (p=0.015, p=0.027).
Conclusions. Metastasis at diagnosis and poor response to preoperative chemotherapy were the most important predictors of survival. Females had a better outcome than males. In our study group, the mifamurtide group`s survival rates were significantly higher. Further large studies are needed to validate the efficacy of mifamurtide.
Modelos y teorías en las ciencias
Authors: Teixidó Durán Óscar Frederic
Published: March 2023

Existen conceptos clave en las diversas ciencias (ya sean formales, naturales, biosociales o sociales) como “teoría” o “modelo” que están aún hoy sujetos a un amplio debate epistemológico, i.e. desde la teoría del conocimiento, y centrada en el estudio del conocimiento científico en particular. Los científicos, pues, construyen y utilizan diferentes nociones que cargan tras de sí realmente con un exhaustivo debate extracientífico sobre su naturaleza. En este trabajo se ofrecerán algunas aclaraciones y propuestas formales de definición sobre tales nociones desde la filosofía de la ciencia del astrofísico y filósofo Gustavo Esteban Romero (G. E. Romero). En concreto se ensayarán unas definiciones formales de “teoría” y “modelo”, para las ciencias actuales (y otras disciplinas pasibles de su aplicación), y se contextualizarán estas ideas en el debate sobre la estructura y organización de los saberes científicos.

The Linguistic Landscape as an Identity Construction Site of a United States’ Higher Educational Institution in the Time of COVID-19
Authors: Im Jae-hyun
Published: March 2023

This study examines how the linguistic landscape of a university in the midwestern United States has changed since the COVID-19 pandemic, and how that change has discursively constructed the identities of the university and its community. The focus lies in the newly displayed semiotics that provides information about preventing the virus from spreading. By analysing public signs such as flyers, posters, and banners whose contents have to do with COVID-19, this study found the following five ways in which the institution and community express their identities and voices. The university’s identity has shifted to that of an agent that acts to encourage a united effort to protect itself and its community; a caring entity that cares about community members; a site for community members’ voice expression; a space creator to expand interaction from physical to online discourses; and an information deliverer for international members of the community. This study calls for research that investigates the global pandemic’s influence on the linguistic landscape.

Published: March 2023

Objectives:

The objectives of this study were to determine the prevalence of sleep paralysis (SP) in medical students from the University of Buenos Aires (UBA).

Materials and Methods:

An ad hoc questionnaire based on the diagnosis of SP and a demographic survey was electronically presented to students of Internal Medicine at the School of Medicine of the UBA. The respondents answered both questionnaires using Google Forms®.

Results:

The prevalence of SP was 40.7% (95% CI 33.5–47.8). A higher percentage of the respondents (76%) reported experiencing SP-related anxiety. An association between self-perceived quality of sleep and the incidence of SP was found (χ2: 12.712, P = 0.002). The highest frequency was hypnopompic SP (55.55%), and the highest percentage (55.4%) suffered from SP less than once every 6 months. Most respondents (59.5%) reported having started with SP symptoms after 18 years of age, and the highest percentage (66.2%) had exacerbated their symptoms at college. The frequency of the Incubus phenomenon was 14.5% (95% CI 6.2–23). Most respondents (70.8%) denied the association of SP with religious or paranormal beliefs.

Conclusion:

SP is highly prevalent in medical students and is associated with poor sleep habits and perceived poor sleep quality. Clinicians should be aware of this parasomnia to avoid a misdiagnosis of psychosis and inform sufferers of the nature of SP.
A brief review of the monkeypox virus and emerging concerns for neuroinvasiveness
Authors: Anand Atul , Das Anand Kumar , Bhardwaj Sona , Singh Saraj Kumar
Published: March 2023

Background:

Amidst the ongoing COVID-19 pandemic, monkeypox virus (MPXV) disease has been recognized as another disease of pandemic nature by the World Health Organization. Nearly four decades after the eradication of smallpox, as half of the world population is naïve to ortho-pox viruses (supposedly due to lack of immunity by vaccination), MPXV remains the most pathogenic species of the family of poxviruses.

Methods:

The articles on MPXV were searched on PubMed/Medline and data were retrieved and analyzed.

Results:

Although reported as a disease of milder exanthem and lower mortality as compared to smallpox, the MPXV disease tends to be neuroinvasive. This article highlights the neurological signs and symptoms of MPXV disease and discusses, in brief, the management strategies.

Conclusion:

Neuroinvasive properties of the virus as demonstrated in in vitro studies, and further verified by neurological illnesses in patients, present a special threat to mankind. Clinicians must be prepared to recognize and treat these neurological complications and start treatment to limit long-lasting brain injury as seen in patients with COVID-19.
Skeletal Transformation of Unactivated Arenes Enabled by a Low-Temperature Dearomative (3+2) Cycloaddition
Authors: Pradhan Sajan , Mohammadi Fahimeh , Bouffard Jean
Published: March 2023

Simple aromatic compounds like benzene are abundant feedstocks, for which the preparation of derivatives chiefly begins with electrophilic substitution reactions, or less frequently reductions. Their high stability makes them particularly reluctant to participate in cycloadditions under ordinary reaction conditions. Here we demonstrate the exceptional ability of 1,3-diaza-2-azoniaallene cations to undergo formal (3+2) cycloadditions with unactivated benzene derivatives, below room temperature, to provide thermally stable dearomatized adducts on a multi-gram scale. The cycloaddition, which tolerates polar functional groups, activates the ring toward further elaboration. On treatment with dienophiles the cycloadducts undergo a (4+2) cycloaddition-cycloreversion cascade to yield substituted or fused arenes, including naphthalene derivatives. The overall sequence results in the transmutation of arenes through an exchange of the ring's carbons: a two-carbon fragment from the original aromatic ring is replaced with another from the incoming dienophile, introducing an unconventional disconnection for the synthesis of ubiquitous aromatic building blocks. Applications of this two-step sequence to the preparation of substituted acenes, isotopically labeled molecules, and medicinally relevant compounds are demonstrated.
Quantum Chemical Modelling of Hemicellulose Fast Pyrolysis: β-D-xylopyranose as a Structural Motif
Authors: Lupi Jacopo , Kelly Mark , O'Shea Ailis , Ghaani Mohammad Reza , Dooley Stephen
Published: March 2023

The aim of this research is to investigate the pyrolytic reactivity of hemicellulose, specifically focusing on β-D-xylopyranose (xylose), as it is a significant component of hemicellulose. Quantum chemistry-based computational techniques, such as density functional theory, post Hartree-Fock methods, and composite schemes, were employed to evaluate the potential energy surfaces for the initial steps of xylose thermal degradation pathways. Conformational analysis of minima and transition states was carried out in order to obtain molecular structure guesses for global minima. To compare the accuracy of this study against other approaches, reference data was obtained from “cheap” composite schemes. In addition, the Arrhenius parameters were derived by fitting rate coefficients computed using transition state theory. These findings are beneficial and will be utilized in developing a kinetic model scheme in the near future.

Published: March 2023

Objective: This study aims to investigate and compare the anticancer effects of carboplatin and cisplatin, frequently used in cancer treatment, by loading them on albumin nanocarrier. Materials and Methods: Carboplatin (CP) and Cisplatin (Cis) loaded albumin nanoparticles were synthesized using ultrasonication as CP-NPs and Cis-NPs, respectively. Nanoparticle size and distribution were evaluated by Dynamic light scattering (DLS). Cytotoxicities of NPs were evaluated in MDA-MB-231 and MCF-7 breast cancer cells and HUVEC using MTT test and their morphological images were compared. Results: While the average size of CP-NPs was around 2-3 nm, Cis-NPs was 7-8 nm. It was observed that both NPs groups were homogeneously dispersed. According to the cytotoxicity results, both CP-NPs and Cis-NPs were more cytotoxic on MCF-7 breast cancer cells. In addition, CP-NPs and Cis-NPs showed significant cytotoxicity on MCF-7, MDA-MB-231 breast cancer cells, while low cytotoxicity was detected in normal HUVEC cells. The NPs treated MCF-7 was compared with the untreated MCF-7 and statistical significance was calculated as P<0.01 for CP-NPs and Cis-NPs. Conclusions: Abumin-based CP-NPs and Cis-NPs showed high cytotoxicity in breast cancer cells, they have low cytotoxicity in healthy cells, making them promising for breast cancer treatment.

Published: March 2023

Objective: Lung cancer has a poor prognosis. Thiol groups with high antioxidant capacity are converted to disulfide bonds through biochemical reactions that neutralize different oxidant compounds. The thiol-disulfide (SH-SS) homeostasis has significant effects on cell mechanisms, transcription, and apoptosis. Here we present the prognostic role of dynamic SH-SS homeostasis in patients operated for NSCLC. Materials and Methods: Patients operating for early-stage NSCLC were prospectively analyzed. SH-SS homeostasis tests were measured using the automated spectrophotometric method. Results: This study enrolled 138 subjects, including 77 patients and 61 healthy controls. Native thiol and total thiol levels were significantly lower in the patient group. The disulfide-to-native thiol ratio, which is an indicator of oxidative stress in SH-SS homeostasis, also reached a level of statistical significance in the patient group (p<0.001). According to the cut-off values (305 and 326.3), the median overall survival rate was significantly shorter in patients with low native thiol and total thiol levels (p<0.001). Conclusions: This study demonstrated decreased native thiol and total thiol levels as well as decreased disulfide levels and SS/SH ratio in early-stage NSCLC. Impaired SH-SS homeostasis may contribute to lung cancer pathogenesis and poor prognosis because of enhanced oxidative stress.

A camera sensor may be a useful tool for a number of robotic and autonomous systems when used with MATLAB Simulink for obstacle avoidance. Using a camera sensor and MATLAB Simulink's optical flow algorithm, the obstacle avoidance system is shown in this work. For the purpose of identifying and following the motion of objects in the picture, the system analyses visual data from the camera. The motion vectors of the objects are computed using the optical flow technique, and the robot and obstacles' relative motion is calculated using those motion vectors. In order to provide safe and easy navigation, the system can recognise and avoid obstacles in real-time. The system is easily adjustable and adaptable to diverse applications thanks to the usage of MATLAB Simulink, which enables the integration of several sensor and control systems. The suggested system's findings demonstrate that using a camera sensor with the optical flow algorithm may be a useful tool for obstacle avoidance in a range of robotic and autonomous systems.
УКРАЇНСЬКОМОВНИЙ ПЕРЕКЛАДАЦЬКИЙ ДИСКУРС (НА МАТЕРІАЛІ ТВОРІВ БРУНО ШУЛЬЦА І ПРО БРУНО ШУЛЬЦА)
Authors: Маторіна Н. М.
Published: March 2023

Метою наукової розвідки є презентація найновіших українськомовних перекладів прозових творів Бруно Шульца і про Бруно Шульца, які вийшли друком 2022 року, для систематизації та узагальнення шульцівського перекладацького дискурсу у сучасних українських літературознавчих студіях. У статті охарактеризовано дві ювілейні «книжкові» події: переклад шульцівської польськомовної енциклопедії «Słownik schulzowski» українською мовою Андрія Павлишина й українськомовний переклад шульцівської збірки оповідань «Корицеві крамниці» Леся Герасимчука, які, наскільки відомо, ще не були об’єктом наукових досліджень сучасних шульцологів. Актуальність дослідження полягає насамперед в оприлюдненні оновленого шульцівсько-українського перекладацького, літературного й літературознавчого дискурсів, що сприяє пришвидшенню повернення Бруно Шульца до українського культурного сьогодення. З’ясовано окремі особливості українськомовного перекладу «Корицевих крамниць» Л. Герасимчука, зокрема порівняно з перекладами І. Гнатюка, Т. Возняка, Ю. Андруховича і власного перекладу авторки статті; визначено роль і значення нових українськомовних джерел для розвитку сучасної українськомовної шульціани. Вочевидь, перекладачі намагаються передати шульцівський текст українською мовою якомога ближче й точніше до польського оригіналу; при цьому кожен перекладач підходить до процесу відтворення тексту індивідуально, зі своїм умінням інтерпретувати текст оригіналу, що дозволяє авторці статті, послуговуючись результатами порівняльного аналізу, вважати переклад Івана Гнатюка найбільше наближеним до шульцівського оригіналу, попри непрості цензурні умови під час перекладу, Тараса Возняка – польсько-єврейсько-галицько-українським з акцентуванням саме на галицькому компоненті, Юрія Андруховича – шульцівсько-українським (за невидимою присутністю перекладача), Леся Герасимчука – власне герасимчуківським, оскільки вочевидь, що перекладач не стільки знайомить читача з польським оригіналом, скільки із суб’єктивним сприйняттям цього оригіналу; власний переклад авторки статті – перекладом пересічного українця, обізнаного з творчістю Бруно Шульца. Авторка висновковує, що шульцівські оповідання можуть бути перекладені українською безліч разів, і кожен із подальших перекладів суттєво відрізнятиметься від попереднього, як це і сталося з перекладом збірки «Корицеві крамниці» Леся Герасимчука.

Authors: Supriyanto Achmad Sani , Ekowati Vivin Maharani , Rokhman Wahibur , Ahamed Forbis , Munir Misbahul , Miranti Titis
Published: March 2023

Purpose: This study aims to examine the relationship between empowerment leadership and organizational innovation. This analyzes the influence of empowerment leadership on organizational innovation, whether knowledge sharing mediates the effect of empowerment leadership on individual creativity, if individual creativity moderates the influence of empowerment leadership on organizational innovation, and how psychological empowerment mediates the effect of leadership on individual creativity.

 

Theoretical framework:  Empowerment leadership includes delegation of authority, participating in decision-making, informing employees about regulations, becoming a role model, showing concern, and interacting with the team members. Organizational innovation is the ability to generate and adopt new ideas or behaviors because it increases productivity and business performance.  Knowledge sharing is a mechanism that fosters individual creative thinking and increases employees' creativity. Therefore, leaders tend to promote the practice of knowledge sharing by generating useful new ideas and thoughts.

 

Design/methodology/approach: Respondents are lecturers at the Faculty of Economics and Business of Islamic Higher Education (IHE) in Java, Indonesia, who have been selected as participants. Data were analyzed using the PLS-SEM to test the modified results of several models.

 

Findings: The results showed that empowerment leadership directly affects organizational innovation, knowledge sharing mediates the influence of empowerment leadership on Individual creativity howevet, it failed to mediate the effect of empowerment leadership on organizational innovation, while psychological empowerment failed to moderate the relationship between variables.

 

Research, Practical & Social implications:  This study added distinctive supports to the leadership literature by identifying key leadership behaviors that foster or impair individual creativity, knowledge sharing and organizational innovation through investigating their relationships with leadership styles in the same research model.

 

Originality/value:  This study indicates that empowerment leadership majorly affects organizational innovation. Furthermore, knowledge sharing plays an important role by mediating between variables for the development of organizational innovation.

In this study, Al2O3, TiO2 and Al2O3+ 3wt%TiO2 coatings were deposited on AZ31 Mg alloy substrate by plasma spraying. The coatings were structurally characterized by scanning electron microscopy and X-ray diffraction. Corrosion experiments were carried out in 3.5% NaCl solution. Adhesion tests were performed according to daimler benz VDI-3198 standard. A coating layer of approximately 70 microns in thickness was deposited. High plasma enthalpy caused phase transformations in alumina-based ceramics. As a result of electrochemical corrosion study, it was determined that the coatings increased the corrosion resistance of AZ31 Mg alloy. While the most corrosion resistant coating is Al2O3+ 3wt%TiO2, the weakest coating against corrosion is TiO2. The adhesion behavior of all coatings to the substrate was at an acceptable quality levels.

Authors: Godik О. S.
Published: March 2023

Objective. On the prehepatic portal hypertension pattern, created by partial ligature of venae portae in rats, to estimate the impact of partial hepatic deportalization on its tissue.

Materials and methods. The investigation was conducted on 35 male rats of a Wistar line, aged 4–6 weeks. In 15 laboratory animals the partial ligature of vena porta with formation of stenosis was conducted, and in 15 –false ligature, while the control group consisted of 5 intact laboratory animals.

Results. There were revealed certain connections between conduction of partial ligature of vena porta and critical (lethal) lowering of portohepatic perfusion.

The model of prehepatic portal hypertension, using partial ligature of vena porta, leading to partial lowering of portohepatic perfusion with development of cavernous transformation of vena porta and dystrophic changes in hepatocytes with further fibrous changes in hepatic parenchyma, was applied.

Conclusion. The portal vein narrowing grade in range 52 – 59% constitutes the optimal one for the prehepatic portal hypertension formation with development of zonal adipose parenchymatous hepatic dystrophy and the balloon degeneration of hepatocytes with further development of fibroses in rats of a Wistar line aged 4 – 6 weeks.

A comparative analysis of the methods used for determination of a number of elements in steels and cast irons by atomic absorption spectroscopy with flame atomization have been carried out (vanadium by COST 12351-2003, GOST 22536.12-88, GOST 2604.7-84; chromium by GOST 12350-78, GOST 22536.7-88, GOST 2604.6-77; copper by GOST 22536.8-87, GOST 12355-78, GOST 2604.9-83, GOST 4943-2010; manganese by GOST 12348-78, GOST 22536.5-87, GOST 2604. 5-84; nickel by GOST 12352 - 81, GOST 22536.9-88, GOST 2604.8-77, GOST 4940-2010; in alloyed and unalloyed steels and alloyed and unalloyed cast irons). Analysis of the data obtained revealed the possibility of combining the considered Russian national standards into universal multi-element methods for the materials under study. The developed methods have been then certified in the analytical laboratory of the testing center of the Institute for certified reference materials (ICRM). The proposed methods provide an extension of the range of determined concentrations under optimal conditions of analysis. Comparison of the developed methods for the determination of vanadium, chromium, copper, manganese, nickel in steels and cast irons with international standards ASTM E350-18, ASTM E351-18, ASTM E352-18 have been carried out.
Lexical and Semantic Features of the Words Nominated for the German Linguistic Awards in 2021

Published: March 2023

This article considers the main lexical and semantic features of German neologisms that were debated in 2021 as the candidates for “Word of the Year”, “Un-Word of the Year”, and “Youth Word of the Year”. All these votes have been held in Germany since the 1970s, and their results are highly credible and of particular research interest to both German and foreign linguists. The lists of winners often spark intense debates regarding the validity of the choice and the reasons behind it. Of course, this brings together the community of linguists and encourages the exchange of views among them. The results obtained here show that neologisms stand out and are widespread because they reflect the evolving world situation and the attitude of the German public toward it. A generalized description of the lexical units that can potentially explain the large-scale popularity and selective use of neologisms in the German language was carried out. The relationship between language and society, with regard to certain social processes taking place in it, was revealed.

In natural languages, segmentation of the speech flow is the most important aspect of speech decoding: the meaning of a linguistic whole can be understood only if it is broken down into smaller elements and these are combined according to the grammatical rules of the language. Thus, the marking of speech segments must be determined by the internal structure of the language. A necessary condition for defining the boundaries of such segments is the presence of cognitive mechanisms involved in the processes of decoding sign systems. For a number of reasons, certain difficulties arise when identifying the boundaries of word forms in the Tatar speech. Therefore, statistical studies on the phonological structure of the Turkic word form and on potential ways of marking its boundaries are of great scientific interest. Through studying the vocal structure of the word form with the allocation of vowel phonemes in the initial and final syllables, this article investigates how the beginning and end of Tatar words are marked at the level of vowels. Literary texts were used as the empirical material for this study. With the methods of mathematical statistics, it was demonstrated that the distribution of eight vowels in the first and last syllables has statistically significant differences. At the same time, only the phoneme ‹a›, which is roughly equally represented in the initial and final syllables, has two different (positionally marked) variants: ‹ао› (labialized ‹a›) in the first syllable and the usual ‹a› in all other syllables. This distribution of vowels enables Tatar speakers to correctly define the boundaries of word forms, along with stress and vowel harmony, which alone are not sufficient for a clear and unambiguous definition of the boundaries of word forms. The results obtained suggest that the statistically significant differences revealed in the distribution of vowel phonemes are of great cognitive importance for the perception and discrimination of signs because they mark the beginning and end of lexical units in the speech flow. In the future, the methodology developed in this work can be used for similar studies on other Turkic languages.
On Numerals with Fuzzy Semantics in the Chinese Language
Authors:   Moscow City University, Moscow, 129226 Russia, Bankova L.L.
Published: March 2023

This article considers the fuzzy (approximate, blurred) semantics of Chinese numerals. Despite their main function of expressing exact numbers, fuzziness is the innate feature of such numerals. Numerals with fuzzy semantics (or so-called imaginaries in the sense of structural linguistics) should not be confused with the approximate ones because they correlate fairly or in no way with actual numbers and bring to the fore the meanings of “much/many” or “little/few.” Here, the views of Russian and Chinese linguists on semantic fuzziness were summarized. The following three factors that determine it were described: transnational, nationally stipulated, and individually determined. Kang Su and Song Guangtian’s classifications of fuzzy numerals were analyzed and critically assessed. The functioning of fuzzy numerals in the Chinese language was discussed from a diachronic perspective. The analysis of the Chinese language history shows that the most common fuzzy numerals are three (meaning “many/much” or “few/little”), numerals denoting numbers that are a factor of three with the meaning of “many/much,” and place numerals such as ten, one hundred, one thousand, and ten thousand, also meaning “many/much.” In general, all numerals verbalizing the first ten numbers can have fuzzy semantics.

Published: March 2023

Background

Lateral flow antigen-detection rapid diagnostic tests (Ag-RDTs) for viral infections constitute a fast, cheap and reliable alternative to nucleic acid amplification tests (NAATs). Whereas leftover material from NAATs can be employed for genomic analysis of positive samples, there is a paucity of information on whether viral genetic characterisation can be achieved from archived Ag-RDTs.

Aim

To evaluate the possibility of retrieving leftover material of several viruses from a range of Ag-RDTs, for molecular genetic analysis.

Methods

Archived Ag-RDTs which had been stored for up to 3 months at room temperature were used to extract viral nucleic acids for subsequent RT-qPCR, Sanger sequencing and Nanopore whole genome sequencing. The effects of brands of Ag-RDT and of various ways to prepare Ag-RDT material were evaluated.

Results

SARS-CoV-2 nucleic acids were successfully extracted and sequenced from nine different brands of Ag-RDTs for SARS-CoV-2, and for five of these, after storage for 3 months at room temperature. The approach also worked for Ag-RDTs for influenza virus (n = 3 brands), as well as for rotavirus and adenovirus 40/41 (n = 1 brand). The buffer of the Ag-RDT had an important influence on viral RNA yield from the test strip and the efficiency of subsequent sequencing.

Conclusion

Our finding that the test strip in Ag-RDTs is suited to preserve viral genomic material, even for several months at room temperature, and therefore can serve as source material for genetic characterisation could help improve global coverage of genomic surveillance for SARS-CoV-2 as well as for other viruses.

Klasik Osmanlı edebî ürünleri hem düşünsel hem de tasavvufî altyapısı gereği görünürden farklı manalar da içeren çok katmanlı bir yapıya sahiptirler. Bir metnin açık ve anlaşılır kabul edilmeyip yorumlanması ve içerdiği gizli manaların ortaya çıkarılması düşüncesi şerhlerin ortaya çıkmasını, bir “tür” hüviyetini almasını sağlamıştır. Farklı tür ve içeriklerde metinler üzerine yazılabilen şerhler çoğunlukla erek dilden farklı bir dilde yazılmış metinleri merkezine almıştır. Ancak bu çalışmanın konusu olan metinlerde de görüleceği gibi kimi zaman şerhe kaynaklık eden eser de şerh metni de aynı dildedir; üstelik şair yahut müellif bu metinlerde ayrıca şârih kimliğine de bürünmüştür. Bu çalışmada da 17. yüzyıl şairlerinden Dânişî Ahmed’e ait olabileceği düşünülen iki gazel ve bunlara yine şairi tarafından yapılan şerhler incelenmiş; çalışmanın sonunda söz konusu metinler transkripsiyonlu olarak ortaya konmuştur. Şairin/şârihin kullandığı üslup ve yönteme dair tespitler sunulmaya çalışılmıştır.
