Authors: Andhita Pundra Rengga , Turistiati Ade Tuti , Nur Muhammad Jamiluddin
Published: January 2022

This study aims to examine the organizational communication control strategy carried out by the Purwokerto Branch of the Islamic Student Association (HMI) to demonstrate the Ratification of the Job Creation Bill (Omnibus Law). The method used is descriptive qualitative using organizational control theory as a theoretical framework. The results showed that the involvement of the Purwokerto Branch of HMI in the Omnibus Law demonstration was a critical intellectual movement that arranged forward a constitutional approach. The simple control aspect is implemented through a three-layer communication mechanism. The solidarity of members towards the three layers of communication constructs communication conduct harmoniously. HMI uses two technical tools for technical control, specifically communication aids and internal identification tools as non-verbal symbols of the organization. There are strict controls to identify members in the demonstration through the symbol. Regarding bureaucracy, this organization prioritizes communication with local authorities regarding the fulfillment of formal rules before holding a demonstration. In addition, organizational procedures are also carefully considered, especially regarding consolidating the organization’s internal communications. Conservative control is implemented by strengthening interpersonal communication with active members or alumni networks spread across various professions. The organizational communication control strategy of the HMI Purwokerto Branch focuses on the harmonization of demonstrations that prioritize aspirational and implementation communication by emphasizing a constitutional approach.

La audiodescripción en los programas de máster en España: entrevistas a profesores, audiodescriptores y empleadores
Authors: Mendoza Domínguez Nuria , Matamala Anna
Published: January 2022

La audiodescripción (AD) es un servicio de apoyo a la comunicación para las personas ciegas o con discapacidad visual y puede considerarse un tipo de traducción intersemiótica. El interés académico en AD se materializa en estudios descriptivos y experimentales, así como en otros centrados en aspectos profesionales y docentes. Sin embargo, son necesarios más estudios sobre la didáctica de la AD en relación con el diseño curricular. Con base en esa necesidad, tras presentar los retos actuales más importantes del diseño curricular en traducción, así como los del Espacio Europeo de Educación Superior, este artículo explora las percepciones obtenidas a través de 15 entrevistas a profesores de cursos de AD en los másteres españoles, a audiodescriptores y a empleadores.

Igualmente, se analizan los criterios tanto para su clasificación tradicional por contenido referencial, como su clasificación por relevancia semiótica en una traducción. En la segunda parte se aplica el método culturotraductológico para analizar culturemas presentes en la obra de Iván Turguénev Rudin y la forma de transponerlos en las diferentes versiones a español existentes por parte de distintos traductores.
La defensa del absolutismo en el reinado de Fernando VII: Antonio Gómez Calderón, regente de España
Authors: Espino Jiménez Francisco Miguel
Published: January 2022

Antonio Gómez Calderón, abogado prestigioso en el Madrid del tránsito del siglo XVIII al XIX favorecido por la monarquía absolutista, rechazó con firmeza el sistema liberal durante la Guerra de la Independencia; de hecho, apoyó el absolutismo como síndico del Ayuntamiento de Madrid y diputado en Cortes, firmante del Manifiesto de los Persas. Posicionamiento que le valió el agradecimiento de Fernando VII en 1814, nombrándolo fiscal del Consejo de Indias. Exiliado en Francia tras el restablecimiento del liberalismo durante el Trienio, no cejó en sus ideas reaccionarias y conspiró para el retorno del poder absoluto. En 1823 acompañó a los Cien Mil Hijos de San Luis en su invasión de España como miembro de las instituciones creadas para el gobierno del país, la Junta Provisional y la Regencia, recompensándole su lealtad Fernando VII con su consolidación en la élite política nacional durante la Década Ominosa. Gómez Calderón representa un ejemplo paradigmático de los miembros de la alta administración del Estado de tendencia realista (entre los que se encontraban los ministros López Ballesteros, Calomarde, etc.) que con su labor de apuntalamiento del absolutismo contribuyeron a que el Antiguo Régimen continuara en España durante más tiempo que en otros países de Europa occidental, por lo que con el presente trabajo realizamos una aportación de interés para comprender la mencionada persistencia y la tardanza en la introducción definitiva de la alternativa liberal.
Comparison of biochemical variables in plasma samples obtained from healthy dogs and cats by use of standard and microsample blood collection tubes
Authors: Whittemore Jacqueline C. , Flatland Bente
Published: January 2022

Objective—To compare results of biochemical analyses performed on plasma samples obtained from healthy dogs and cats by use of standard and microsample blood collection tubes.

Design—Evaluation study.

Animals—29 healthy client-owned animals (14 dogs and 15 cats).

Procedures—A blood sample (3 mL) was collected from each animal; 2.5 mL was transferred into a vacuum tube that contained lithium heparin, and 0.5 mL was transferred into a microsample tube that contained lithium heparin. Variables evaluated were albumin, bicarbonate, BUN, calcium, chloride, cholesterol, creatinine, glucose, phosphorus, potassium, sodium, total bilirubin, and total protein concentrations and alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and creatine kinase activities. Results for the 2 types of tubes in each species were compared by use of Pearson correlation coefficients, Passing-Bablok regression analysis, and Bland-Altman analysis.

Results—Data were normally distributed, except for creatine kinase activity of cats. The Pearson correlation coefficient was minimal for total bilirubin concentration in cats and moderate, high, or very high for all other variables. Constant bias for cholesterol and glucose concentration in dogs was identified during Bland-Altman analysis, although the mean difference between types of blood collection tubes was small. No constant or proportional bias for any other variable was revealed by regression analysis or Bland-Altman analysis.

Conclusions and Clinical Relevance—Samples obtained from healthy dogs and cats by use of microsample blood collection tubes that contained lithium heparin provided clinically equivalent biochemical results, compared with results for samples obtained by use of standard blood collection tubes, and minimized the total sample volume collected for diagnostic testing.
Detection of antibodies against Leptospira serovars via microscopic agglutination tests in dogs in the United States, 2000–2007
Authors: Gautam Raju , Wu Ching-Ching , Guptill Lynn F. , Potter Adam , Moore George E.
Published: January 2022

Objective—To use results of microscopic agglutination tests (MATs) conducted at a commercial veterinary diagnostic laboratory to determine temporal and demographic distributions of positive serologic test results for leptospirosis in dogs and identify correlations among results for various Leptospira serovars.

Design—Serosurvey.

Study Population—MAT results for 33,119 canine serum samples submitted to a commercial veterinary diagnostic laboratory from 2000 through 2007.

Procedures—Electronic records of MAT results for dogs were obtained from a veterinary diagnostic laboratory. Seropositivity for antibodies against Leptospira serovars was determined by use of a cutoff titer of ≥ 1:1,600 to reduce the possible impact of postvaccinal antibodies on results. Correlations between results for all possible pairs of serovars were calculated by ordinal ranking of positive (≥ 1:100) antibody titer results.

Results—2,680 samples (8.1%; 95% confidence interval [CI], 7.8% to 8.4%) were seropositive for antibodies against Leptospira serovars. The highest percentage of positive MAT results was for the year 2007 (10.2%; 95% CI, 9.5% to 10.9%) and for the months of November and December during the study period. Antibodies were most common against serovars Autumnalis, Grippotyphosa, Pomona, and Bratislava. Seroprevalence of leptospirosis was lowest for dogs > 10 years of age but was similar across other age strata.

Conclusions and Clinical Relevance—Leptospirosis can affect dogs of small and large breeds and various ages. Although an increase in proportions of positive MAT results was evident in the fall, monthly and annual variations suggested potential exposure in all months. Because of the limitations of MAT results and the limited number of serovars used in the test, bacterial culture should be used to identify infective Leptospira serovars.
Automatic Identification of Wrist Position in a Virtual Environment for Garment Design
Authors: Chen Yu , Hou Qinhua , Hong Yan , Gao Weihong
Published: January 2022

With the development of virtual reality, computer-aided design has shown its strength in the garment product development process. Wrist position corresponds to the styloid process of the ulna (SPU). Due the problem that the SPU position is usually not the finest position of the forearm, the wrist position identification in the 3D clothing design is quite important. This paper proposes a method that uses a fixed-step search algorithm based on existing proportion methods to determine the position of the SPU. The accuracy and efficiency of the proposed method has been validated using 100 samples by comparison with the existing methods. It can be fully applied to a virtual 3D-to-2D garment prototyping process and ensure the automation of this process.
Are swimming coaches ready to help injured young swimmers?
Authors: Dimitrić Goran , Jakšić Milorad , Sadri Filip , Zenić Nataša
Published: January 2022

Study aim: This study aimed to determine the knowledge and skills of swimming coaches in providing first aid and cardiopulmonary resuscitation (CPR).

Material and methods: The sample consisted of 59 swimming coaches who responded to non-standardized questionnaire. The collected data were processed by the statistical program IBM SPSS (20.0), using the Chi-square test with cross-tabulation, with a level of statistical significance p ≤ 0.05.

Results: Obtained data showed a statistically significant difference in the knowledge of swimming coaches about first aid and CPR in relation to coaching experience (p = 0.025); in the knowledge of providing first aid and CPR between coaches who have a certificate of first aid and CPR and those who do not (p = 0.006) and in first aid and CPR knowledge between coaches who have renewed their first aid and CPR knowledge and those who did not (p = 0.045).

Conclusion: Based on the findings of the present study, swimming coaches included in this research did not have enough knowledge and skills in first aid and CPR, which makes swimming programs unsafe. By obliging swimming coaches to acquire and constantly improve their knowledge and skills in first aid and CPR, the environment for all swimming programs would become safer.
The Influence of Selected Strain-Based Failure Criteria on Ship Structure Damage Resulting from a Collision with an Offshore Wind Turbine Monopile
Authors: Niklas Karol , Bera Alicja
Published: January 2022

Offshore wind farms are developing well all over the world, providing green energy from renewable sources. The evaluation of possible consequences of a collision involves Finite Element computer simulations. The goal of this paper was to analyse the influence of selected strain-based failure criteria on ship damage resulting from a collision with an offshore wind turbine monopile. The case of a collision between an offshore supply vessel and a monopile-type support structure was examined. The results imply that simulation assumptions, especially the failure criteria, are very important. It was found that, using the strain failure criteria according to the minimum values required by the design rules, can lead to an underestimation of the ship damage by as much as 6 times, for the length of the hull plate, and 9 times, for the area of the ship hull opening. Instead, the adjusted formula should be used, taking into account both the FE element size and the shell thickness. The influence of the non-linear representation of the stress-strain curve was also pointed out. Moreover, a significant influence of the selected steel grade on collision damages was found.
Analysis of the Pre-Injection System of a Marine Diesel Engine Through Multiple-Criteria Decision-Making and Artificial Neural Networks
Authors: Rodriguez C.G. , Lamas M.I. , Rodriguez J.D. , Abbas A.
Published: January 2022

The present work proposes several pre-injection patterns to reduce nitrogen oxides in the Wärtsilä 6L 46 marine engine. A numerical model was carried out to characterise the emissions and consumption of the engine. Several pre-injection quantities, durations, and starting instants were analysed. It was found that oxides of nitrogen can be noticeably reduced but at the expense of increasing consumption as well as other emissions such as carbon monoxide and hydrocarbons. According to this, a multiple-criteria decision-making (MCDM) model was established to select the most appropriate parameters. Besides, an artificial neural network (ANN) was developed to complement the results and analyse a huge quantity of alternatives. This hybrid MCDM-ANN methodology proposed in the present work constitutes a useful tool to design new marine engines.
Assessing the Potential Replacement of Mineral Oil with Environmentally Acceptable Lubricants in a Stern Tube Bearing: An Experimental Analysis of Bearing Performance
Authors: Kowalski Jerzy , Leśniewski Wojciech , Piątek Daniel , Przybylska Dominika Cuper
Published: January 2022

This study compares the performance of a plain bearing, with a similar structure to a tail shaft stern bearing, lubricated with either mineral oil or an environmentally acceptable lubricant (EAL). The main characteristic of the bearing is its length/diameter ratio of <1. Measurements are carried out with the bearing operating under loads from 0.5 to 1 MPa and seven speeds ranging from 1 to 11 rev/s. The bearing lubricated with either mineral oil with a viscosity grade of 100 or an environmentally acceptable lubricant (EAL) with a viscosity grade of 100 or 150 is investigated according to the ISO standard. Bearing wear is simulated by increasing the clearance circle by 0.1 mm. According to the results obtained, the use of an EAL in place of mineral oil does not cause significant changes in the bearing performance, regardless of the value of the clearance radius. The pressure distribution in the oil film, bearing load carrying capacity, eccentricity and friction coefficient have similar values for the entire load and speed ranges considered, and the discrepancies in the results are within the range of the measurement errors. Only an increase in EAL viscosity causes significant changes in bearing performance and these changes comply with the general theory of lubrication.
Influence of solid particle contamination on the wear process in water lubricated marine strut bearings with NBR and PTFE bushes
Authors: Piątkowska Ewa
Published: January 2022

This paper reports on a study of the influence of solid particle contamination on the wear process in water-lubricated slide bearings (steel-acrylonitrile-butadiene rubber (NBR) and steel-polytetrafluoroethylene (PTFE)). To compare the wear of the shaft journal and bushes (NBR and PTFE) when lubricated with fresh water and contaminated water, an experiment was carried out to identify key factors that influence the state of wear of slide bearing. The amount of wear was checked by means of geometric structure measurements on the journals, namely, roughness profile measurements using both a contact profilometer and an optical microscope. The obtained results enabled correlations between the material comprising the sliding sleeve, roughness of the journals and contamination inside the water-lubricated slide bearings.
State Bastardisation And Terrorism In Nigeria: A Discourse
Authors: Okon Enoch Ndem , Williams Dodeye Uduak , Mmaduabuchi Okeke Godwin. S
Published: January 2022

This paper seeks to unearth and analyse the variables which promote and sustain primordial groups’ identities and their linkages to the emergence and sustenance of terrorist groups in Nigeria. Grounded in the pluralist theory of sovereignty, the study adopts historical research design. It relies solely on data from secondary sources, which are presented qualitatively, and the finding is analysed using content analysis techniques. The study reveals that the promotion of primordial identities above national identity for political advantage by the political elites leads to state bastardisation in Nigeria. Besides, it identifies the apostolical promotion of some neoliberal values without corresponding citizenship education, as responsible for the emergence of Boko Haram and other such groups that challenge the sovereignty and legitimacy of the Nigerian state. It also questions the continuous promotion of religion in the public domain in a secular state and concludes that genuine integration policy is an urgent imperative. The study recommends that ethno-religious politics be buried; religion should be returned to the private lives of the citizenry. Besides, citizenship education and societal development should be prioritised in order to strengthen the state, and weaken the capacity of primordial groups to challenge the Nigerian State with violent outbursts.
Fight For Media Pluralism Or Just “JanŠA’S War On Media”?
Authors: Bratina Rok
Published: January 2022

Since Janez Janša’s government has been installed, not a day has gone by that the ruling coalition party, SDS (the Slovenian Democratic Party), has not been accused of undermining the freedom of media or threatening media pluralism. Sometimes, critics go even further in condemning Janša as wilfully subordinating media to politics. Regarding subordination, independent media studies from 2002, 2006, 2007, 2008 and lastly 2020 haveclearly indicated that the media in Slovenia are to a certain extent already under the influence of politics, namely those close to the left circles. Whilst scientific conclusions prove the fact that changes in media legislation are more than needed, the question that arises is whether the proposers are looking at the concept of media pluralism from the right perspective. Leaning on the most recent Media landscape research, this article stands out from the rest as it draws parallels with the state of political pluralism, demonstrating how partial and imbalanced covering of news could lead to the domination of one political spectrum. Further, we do a historical review of the right-wing media policy and bring to light those aspects that have undergone the sharpest criticism when it comes to media pluralism. In addition, new ideas for future research are discussed.
Reconciliation Between the Victim and the Perpetrator-Restorative Justice
Authors: Aliu Albana , Arifi Besa
Published: January 2022

The purpose of this research is to study and address the relation between the perpetrator and the victim, in particular the way it is regulated in the Republic of Kosovo by comparing it with the regulation in other countries. A long time ago criminal law in its institutes has paid attention only to the perpetrator, trying to guarantee his fundamental rights, it is enough to stop at the institute of presumption of innocence and many other institutes and we can see how importance criminal law and in particular criminal procedure has paid to the perpetrator, and on the other hand the victim has always remained in the shadows.

Therefore, today we find it reasonable to address this issue, to find out from which period criminal law and authors of criminal law turn their heads towards the victim, to find out what is the position of the victim in society today, what steps have been taken in legal terms and also special attention will be paid precisely to restorative justice as a key point for the realization of the rights of the victim, the compensation of the damage and the restoration of balance and the establishment of relations in society. And it is quite important that in addition to the relations that perpetrators have with victims, we also try to understand the historical course of restorative justice and this way to make an analysis of the position of the victim and the perpetrator over the decades.
UNESCO’s Atlas on Endangered Languages and the Local Context
Authors: Poshka Agim
Published: January 2022

This article analyses the overall development of the endangered language around the world in reference to UNESCO’s Atlas of World Endangered Languages and reflects on the local context. The focus to local context refers to the current territory of North Macedonia in which it is believed there are 7 endangered languages such as: Adyge, Aromanian, Gagauz (South Balkans), Megleno-Romanian, Judezmo, Romani and Torlak. These languages are classified as endangered but are still spoken in the country. The article also reflects on the status of the Albanian language in North Macedonia by drawing comparisons with two other language varieties such as Arberesh which spoken in Southern Italy and Arvanitika spoken in Greece. The challenges that these minority languages have faced in particular countries should serve as a guide in designing effective language policies in North Macedonia in order for the language not be endangered. In the last section the article report on the phenomena of Globalization in which English has become the global language and at the same time has accelerated the loss of many native languages around the globe.
Challenges of the Albanian Language in the Internet Era
Authors: Adili-Çeliku Luljeta , Shehabi-Veseli Meral
Published: January 2022

Language is a live organism and as every other living being develops and is enriched with new words and terms, which enter the life of society together with the new tool, i.e. they enter in and mix with the order of Albanian words. Such a thing is inevitable and in some cases even useful, but every word that is lined up in the order of Albanian words must be well filtered. “The introduction of new words and exclusion of old ones is a natural process, and it happens in any language. This is what happened with the Greek borrowings in Latin, with the Arabic borrowings in Greek, with the Latin borrowings in many European languages, with the Persian borrowings in Turkish, with the Turkish borrowings in Albanian, etc.” - Prof. Hajri Shehu emphasizes in a scientific interview (Shehu, 2017). In recent decades, with the expansion of the Internet, many foreign words began to enter and be used in the Albanian language. English took up more space than expected; in addition to penetrating through various tool notions, it also replaced centuries-old native words of Albanian.

The paper has been divided into three parts and in each part an issue has been dealt with: the first part talks about the use of foreign words and the existing words in Albanian; the second part deals with the use of emoticons used instead of words and the third part deals with writing errors in the Albanian language. These are some of the issues that have created a great concern for the Albanian language in this century and they certainly need to be addressed seriously to prevent the dangers that may threaten it.
Investigation of changes in the skin blood microcirculation when performing the hatha yoga breathing technique
Authors: Frolov A. V. , Loktionova Yu. I. , Zharkikh E. V. , Sidorov V. V. , Krupatkin A. I. , Dunaev A. V.
Published: January 2022

Introduction. Yoga breathing exercises improve the ability to significantly reduce the respiratory rate. A decrease of the minute respiration volume results in compensatory reactions of the microcirculatory bed caused by changes in the gas composition. The reaction of the regulatory mechanisms of the microvascular bed can be evaluated by the optical non-invasive laser Doppler flowmetry method. The aim of the study was to assess the tissue microcirculation parameter changes in people performing yoga breathing exercises. Materials and methods. 25 volunteers performed yoga breathing exercises at a frequency of 3 times per minute, 2 times per minute, 1.5 times per minute, 1 time per minute for 5 minutes, and free breathing for 6 minutes before and after breathing exercises. Parameters aimed to defin the reaction of skin microcirculation in different body areas were simultaneously recorded in six sites by laser Doppler flowmetry using a distributed system of wearable analyzers. The parameters of tissue microcirculation recorded by the method of laser Doppler flowmetry were: the index of microcirculation (Im), nutritive blood flow (Imn), the amplitude of myogenic (Am), neurogenic (An), endothelial (Ae), respiratory (Ar) and cardiac (Ac) regulation circuits. Results. Yoga breathing exercises led to increase of microcirculation index at all breathing frequencies. Breathing at a frequency of 1.5 and 1/minute leads to a significant increase in nutritional blood flow. Low-frequency breathing exercises lead to an increase in blood pressure at the lowest breathing rates – 1.5/minute and 1/minute. The most significant changes were achieved at the lowest respiration rates (1 and 1.5/minute), that could be associated with hypoxic-hypercapnic mechanisms. Conclusion. The absence of significant changes in microcirculation parameters after low-frequency respiration during measurements in the supraorbital arteries in both groups characterizes the work of homeostatic mechanisms for maintaining brain perfusion in stressful situations for the body (low-frequency types of respiration, hypercapnia and hypoxia). When measured in the extremities, a change in the effect of the circulatory system regulatory mechanisms was observed; along with an increase in skin perfusion and the nutritional component, it can characterize the compensatory reaction of the microcirculation to respiration change.

Purpose. To study the effect of short-term hypoxic exposure on correlation between microcirculatory parameters (MCR) of symmetric areas of the human head. Materials and methods. MCR parameters of 10 healthy male volunteer were measured by laser Doppler flowmetry method. Short-term hypoxic exposure was produced according to the hypoxic test method using the ReOxy Cardio unit (S. A. Aimediq). We assessed the perfusion metrics left and right areas of interest, neurogenic, myogenic, respiratory and cardiac contributors to vascular tone and correlations between baseline parameters and after hypoxic exposure. Results. We revealed the specificity of regional circulation system rearranging induced by hypoxic load. The specificity is caused by functional asymmetry of correlations between different vascular tone contributors in symmetrical head areas. Strong correlation declining under the hypoxic loads between baseline perfusion on left/right was found. The perfusion changes of symmetrical temporal areas under the hypoxic loads correlate negatively with the baseline perfusion of both the same and the opposite side. Conclusion. Short-term hypoxic load rearranges the balance of different vascular tone contributors regulatory role in MCR of symmetric head areas to maintain the sustainable activity of the whole MRC.
Where the Translingual Rubber Hits the Road: Ideological Frictions, Mixtificaciones y Potentialities in Bilingual Teacher Preparation Programs
Authors: Muñoz-Muñoz Eduardo
Published: January 2022

Translanguaging has become a particularly relevant (and controversial) concept for the field of bilingual education, with concrete implications for teacher preparation programs serving teacher candidates (TCs) who may identify as heritage speakers of Spanish. However, the regard and understanding of translanguaging, its pedagogical potential, and the positionality to implement it are not evenly distributed among stakeholders involved in the teacher preparation process. This article explores the relationship among California public teacher preparation programs, their bilingual teacher candidates, and the districts that host their field placements that ultimately hire them. Building on the metaphorical concepts of ideological and implementational spaces (Flores & Schissel, 2014), the space between and encompassing the overlap between credentialing programs and school districts is characterized as a friction space beset by tensions between monoglossic and heteroglossic stances and the pragmatism of “entering the workforce.” The dynamics of this space are illustrated in five retratos constructed on qualitative data obtained through semistructured interviews. Based on the author's localized experiences, the article concludes by proposing approaches to navigate the friction space, reinforce the bilingual candidates' counterideological stances, and advance a much-needed productive dialogue in the teacher preparation ecology.
Ruptures of Possibility: Mexican Origin Mothers as Critical Border Pedagogues
Authors: Nuñez Idalia , García-Mateus Suzanne
Published: January 2022

In U.S. schools, educators are often regarded as knowledge producers and sole pedagogues, whereas parents (particularly of Color) are perceived as not engaged or interested in their child(ren)'s education (Colgrove, 2019; Nuñez, 2019; Ramirez, 2020). These negative stereotypes and white-centered discourses sustain raciolinguistic perspectives (Rosa & Flores, 2017) of families of Color and immigrant backgrounds. For the present study, we employed critical discourse analysis to explore why and how Mexican mothers raise bilingual children by examining how their experiences inform us about their powerful roles as critical translanguaging pedagogues. Drawing on border thinking and pedagogy of border thinking, the findings revealed two main themes: (1) how mothers recognize and draw on the ruptures of cultural and linguistic worlds, and (2) how they sustain language through family and cultural practices.

Introduction. Acute respiratory infections are the most common infectious diseases worldwide among children of different age groups. Materials and methods. 59 children between the ages of 3 and 7 participated in the study. The first group included 22 patients with an acute respiratory viral infection, the second one consisted of 23 patients with acute respiratory viral infections associated with adenoid vegetation, and 14 apparently healthy children were included in the control group. Immunology research was conducted during the acute period of the disease. Statistical processing of received data was done with the standard statistical software EZR 1.41. Results. After the research, most of the patients with acute respiratory viral infections were identified an actual increase in CD3+, CD4+, CD8+, CD22+- cells and IgA, IgM in the blood serum. Simultaneously, in patients with acute respiratory viral infections associated with adenoid vegetation during the acute period, the increase in total lymphocytes was identified due to CD4+, CD8+, CD22+ cells and IgG. A comparative analysis of the study results of both groups of patients showed that children from the second group had a significantly higher level of CD3+- cells, while the CD22+- lymphocytes, IgA, IgM and IgG were significantly lower from the similar indicators of the first group. Conclusions. The acute period of the disease in children with acute respiratory viral infections, associated with adenoid vegetation, had an imbalance in both the cell and the immune system's humoral component

Introduction. Medullary thyroid cancer (MTC) belongs to a class of rare neuroendocrine aggressive tumors and arises from parafollicular cells (C-cells). An important modern problem is the development of ways to predict the recurrence of this disease. The aim of the study is to determine the role of immunohistochemical tumor markers of medullary thyroid cancer in predicting recurrence or death. Materials and methods. The analysis of the prospective study included 22 patients with MTC, 5 of whom have developed a recurrence and 4 have died at the end of the 10-year (120 months) follow-up period. Immunohistochemical examinations were performed using monoclonal antibodies of tumor markers calcitonin, chromogranin A, vimentin and Ki-67. Results. The discrepancy between the data of histological and immunohistochemical examinations in MTC is 12.0%, which indicates the hyperdiagnosis of this nosology and argues the importance of performing immunohistochemical examinations to verify the diagnosis. Patients who had a recurrence of MTC had significantly (p <0.05) lower levels of calcitonin expression (5.00 [5.00; 5.00] points) compared with patients who did not relapse, where this figure was 6.00 [6.00; 7.00] points. In patients with MTC, an increase in calcitonin expression was significantly associated with an increase in chromogranin A expression (r = + 0.49, p = 0.02); a similar relationship was found for the proportions of immunopositive cells of these tumor markers: r = + 0.68, p = 0.001. At the same time, it was found that the increase in the level of calcitonin expression was apparently combined with the decrease in the level of Ki-67 expression (r = -0.52, p = 0.02). It was also found that the increase in the level of vimentin expression is combined with an increase in the expression (r = + 0.64, p = 0.001) and the proportion of immunopositive cells of chromogranin A (r = + 0.45, p = 0.038). Conclusions. Low levels of calcitonin expression are prognostically unfavorable markers for the recurrence of MTC. Specific tumor markers are important in the treatment process and for the dynamic monitoring of patients with MTC.

Introduction. Biomarkers of biological age (BA) are essential for anti-aging research and practice because of their prediction of life expectancy, detection of premature aging, and estimation of anti-ageing programs' effectiveness. The purpose of this study is a clinical validation of the method of biological age estimation based on the analysis of heart rate variability (HRV), artificial intelligence technologies, and biometric monitoring. Methods. In 51 patients who received wellness and rehabilitation services in the medical center "Edem Medical", biological age was determined based on the analysis of HRV and machine learning algorithms. A comparison was made between the proposed method and other known methods of biological age estimation. Biological age estimation by physicians which is based on the Frailty Index was chosen as a reference method. The second method was DNA methylation age (DNAm PhenoAge). This method predicts biological age based on nine parameters of blood (albumin, creatinine, glucose, C-reactive protein, lymphocytes [%], mean corpuscular volume [MCV], red cell distribution width [RDW], alkaline phosphatase, WBC count). Using the «leave one out» technique, an additional algorithm was created for approximating biological age in view of blood test parameters and ECG signals as input data. Morning HRV assessment was performed on empty stomach and after 10-minute rest in horizontal position. ECG was recorded using Mawi Vital multisensor device. The following statistical tests were used to reveal associations between different methods of biological age estimation: 1. bivariate correlation, 2. mean absolute error (MAE), 3. qualitative binary age estimation. Results. All tested methods of BA evaluation were strongly correlated with the reference method (physician-determined age). HRV based approach was superior in comparison with other methods. In 9 out of 10 cases, the qualitative binary age assessment using HRV coincided with the reference method. The HRV method was the most accurate for biological age estimation (3.62 vs 12.62) based on MAE. Conclusion. The method based on HRV is an affordable and convenient approach to biological age estimation. This method offers opportunities for early stratification of individuals at risk of accelerated aging. It combines well with the paradigm of 3 P medicine which is based on Prevention, Prediction, and Personalized approach to each patient

Microplastics (particles with a size of less than 5 mm) are a rising environmental problem. Microplastics can disseminate in the air and accumulate in sediments as well as in microorganisms and humans, due to their small size. Sediment is considered to be the major repository of microplastics, particularly those of the PE type. Microplastics in massive amounts accumulated in sediments, perhaps as a result of point sources or diffuse contamination. Microplastic contamination can spread from industrial production facilities, urban areas, agricultural areas, or the air. The current study was carried out to explore the occurrence of MPs in sediments at discharge sources by evaluating 27 sediment samples taken from 9 distinct waste sources from industrial activity locations to determine the amount of microplastic contamination in sediments at discharge sources. Microplastics with relatively high density were found in all sediment samples in this research, ranging from 2,900 to 238,200 particles/kg dw. The most prevalent microplastics detected in sediment samples at these sites were fibers and fragments, accounting for 59-94% and 6-41%, respectively. Fiber microplastics ranged in size from 1000 to 9,000 µm, whereas fragment microplastics ranged from 200,000 to 2,100,000 µm2. Microplastics with < 1000 µm and 1000-2000 µm sizes accounted for a significant portion of the total, reaching 21.05-37.84% and 39.74-61.17%, respectively. The hue of microplastic particles in sediment samples obtained was highly varied.
