Authors: Afonichev K. A. , Filippova O. V. , Baindurashvili A. G. , Buklaev D. S.
Published: November 2021

The cicatrical deformities of the foot and secondary changes in tendons, muscles and in osteoarticular system with respect to the age and scar location were discussed. It was pointed to a high risk of early development of foot deformities, especially in young children up to five years of age. This indicates the need for regular medical check-up. Clinical experience shows that the hypertrophic scars that extend from the lateral surfaces of the foot to the ankle region create preconditions for development of multiplanar foot deformities, especially in the period of intensive growth of the skeleton. Possible complications in the treatment of multiplanar foot deformities in the presence of scar lesions of surrounding tissues associated with an increased risk of trophic disorders and the development of the inflammatory process are considered. Recommendations on stages of surgical treatment are given.

Authors: Voronkevich L. A. , Tikhilov R. M.
Published: November 2021

Twenty two patients were operated on account of joint surface deformities developed due to malunion of healed tibial condylar impressions. The peculiarity of operation was the osteotomy line, which contoured the perimeter of impression to mobilize it, and after that the fragments were plated with bone grafting. Early function is essential. We met one deep infection. The late follow-up was generally positive. The intrajoint osteotomies can effectively restore posttraumatic deformities of tibial condylar surface and normalize the anatomy with good function and low pain. This operation optimizes anatomic and functional conditions for probable joint replacement and is able to delay the need in it at least for decade and for thus decrease the problems of revisions.

Authors: Shamiyah Khalid Adnan , Whitebridge Simon , Kumar Nitya , Atkin Stephen , Ali Khawla Fuad , Aljenaee Khaled
Published: November 2021

BACKGROUND

Due to the COVID-19 pandemic, telehealth has emerged as a safer way to access healthcare. The telehealth industry has been rapidly expanding over the last decade as a modality to provide patient-centered care. However, the prevalence of its use and patient acceptability remains unclear in the Middle East and North Africa (MENA) region.

OBJECTIVE

The primary aim was to assess the prevalence of telehealth use before and during the pandemic by utilizing social media (Instagram) as an online platform for survey administration across different countries simultaneously. Our secondary aim was to assess the perceptions regarding telehealth usage amongst those utilizing it.

METHODS

An online social media platform (Instagram) that reaches 130,000 subjects daily, was used to administer a questionnaire that assessed the current prevalence of telehealth use and public attitudes and acceptability towards this modality of healthcare delivery during the COVID-19 pandemic.

RESULTS

1524 respondents participated in the survey (females 89.3%; age range 25-38) of whom 91.2% lived in the GCC. Prior to COVID-19, 1440 (88%) had no exposure to telehealth. Following the covid-19 pandemic telehealth usage increased by 237% to a total of 644 users (40%) (follow-up consultations (n=410, 47%); first-time consultations (n=348, 40%)) that was associated with older age (p=0.001), having one or more comorbidities (p=0.001), taking one or more pills (p=0.001), living in the GCC (p=0.003). Those who reported using telehealth (n=679), 247 (36.4%) reported their willingness to continue using telehealth, 254 (37.4%) were unsure and 178 (26.2%) did not wish to continue to use telehealth after the COVID19 pandemic. An inverse relationship between telehealth usage and the increasing number of medical comorbidities was shown (OR= 0.76, p= 0.023). Respondents using messaging or video telehealth usage were more likely recommend virtual visits than those who used audio calls (OR= 0.49, p= 0.024). Overall, there was general satisfaction with telehealth usage and respondents found telehealth to be equally effective to in-person visits.

CONCLUSIONS

Telehealth usage increased dramatically and was found to be acceptable though less so if there were other comorbidities; however, further innovation to increase telehealth acceptability is needed if this is to have greater future utility in healthcare delivery.

Background. The imbalance of innate defense early mechanisms in children from pathogens — peroxidation and antioxidant system, can lead to a decrease in the efficiency of the entire immune system. The study of the lipid peroxidation (LPO) and antioxidant protection (AOP) status in children with recurrent acute respiratory diseases will complement the scientific data on the antimicrobial immunity formation processes. The study was aimed to increase the information value of timely detected pro- and antioxidant processes disorders in children with recurrent acute respiratory diseases by studying the primary, secondary, tertiary, and quaternary compounds of LPO and AOP in the serum. Materials and methods. Sixty children aged from 2 to 5 years were examined. Two groups were formed: group 1 — children with respiratory acute infectious more than six times per year (n = 30); group 2 — children with respiratory acute infectious six or fewer times per year (n = 30). Results. The children in group 1 more often presented with high serum levels of lipid hydroperoxides (by 80.0 %; p < 0.05), diene conjugates (by 80.0 %; p < 0.05), malonic dialdehyde (76.7 %; p < 0.05), diene ketones (76.7 %; p < 0.05), Schiff bases (76.7 %; p < 0.05). ceruloplasmin (80.0 %; p < 0.05), superoxide dismutase (80.0 %; p < 0.05), glutathione peroxidase (86.7 %; p < 0.05), catalase activity (86.7 %; p < 0.05). The values of retinol, tocopherol, ascorbic acid in children in the observation groups did not differ statistically significantly. Conclusions. The children aged from 2 to 5 years old with recurrent acute respiratory diseases have an imbalance of the LPO and AOP systems. It was characterized by a simultaneous increase in the serum content of the primary, secondary, and end-products of LPO, enzymes of anti-peroxide and anti-oxygen protection against the background of the lack of adaptive increase in the content of anti-radical compounds.

Authors: Dinç Engin , Arslan Serdar
Published: November 2021

Background. To examine the effects of sports participation in obese boys on body mass index (BMI), waist circumference, hip circumference, muscle strength, muscular endurance, balance and agility. Materials and methods. Sixty-three obese children with a mean age of 10.80 ± 0.58 were included in the study. Participants participated in sports, including judo, table tennis and basketball, for three months at their schools. Body weight, waist circumference and hip circumference of the participants were measured before and after participating in sports. Before and after participating in sports, grip strength, bent arm hanging, single-leg stance balance and plate tapping tests were applied to the participants. Results. While before participating in sports, BMI, waist and hip circumference outcomes of the participants were 23.04 ± 2.89 cm/m2, 81.61 ± 8.56 cm and 87.69 ± 6.52 cm, respectively; after participating in sports, BMI, waist circumference and hip circumference outcomes were 22.51 ± 2.88 cm/m2, 79.38 ± 8.74 cm and 85.73 ± 6.65 cm, respectively. The results of the single leg balance and bent arm-hanging tests after participation in sports increased compared to the results which before participating in sports (p < 0.05). However, the results of plate tapping test results that after participation in sports were less than the results which before participating in sports (p < 0.05). The result obtained from the grip strength after participation in sports was not different from the result obtained before participating in sports (p > 0.05). Conclusions. Participation in regular sports in obese children has positive effects on BMI, waist circumference and hip circumference, which are associated with chronic diseases. Additionally, the participation of obese children in regular sports contributes to the development of physical fitness parameters, which are indicators of health.

Published: November 2021

Background. An integral part of a child’s physical and mental development is a balanced diet. Insufficient or inadequate for a child developing organism’s needs nutrition in preschool age leads to a delay in physical, cognitive, and mental development. The study was aimed to assess the macro-and micronutrient provision status of preschool children with psychomotor developmental delay, identify the presence of macro- and micronutrient deficiencies, define the connection between macro- and micronutrient levels in patient’s serum and psychomotor developmental disorders. Materials and methods. The study analyzed the results of biochemical blood tests of blood serum samples for total calcium, magnesium, and iron level in 30 preschool children with psychomotor developmental disorders. Results. Mental retardation was observed in 53.33 % of examined children, autism spectrum disorders — in 20 % of examined children; minimal brain dysfunction — in 13.33 %, attention deficit hyperactivity disorder (ADHD) — in 13.33 %. 93.33 % of examined children had a deficiency of total calcium, magnesium — in 63.33 %, iron — in 20 %. Ten percent of patients had a deficiency of both total calcium, magnesium, and iron; one child (3.33 %) had no deficits. The most common deficiency in almost all subgroups of examined children was a combined deficiency of total calcium and magnesium. Only in the minimal brain dysfunction subgroup, in 50 % of cases, there was a combined deficiency of total calcium and magnesium, and in other 50 % of cases — an isolated deficiency of total calcium. This study identified a reliable inverse correlation of moderate strength between the level of total calcium and psychomotor development disorders and between the level of magnesium and the hyperexcitability syndrome. This study detected a weak unreliable correlation between the levels of magnesium and neurological disorders; an inverse unreliable weak correlation was found between iron and psychomotor developmental disorders. Conclusions. The most common deficiency in almost all subgroups of examined children was a combined deficiency of total calcium and magnesium. This study identified a reliable inverse correlation of moderate strength between the level of total calcium and psychomotor developmental disorders and between the level of magnesium and the hyperexcitability syndrome. There is also a weak direct unreliable correlation between magnesium level and psychomotor disorders. An inverse unreliable weak correlation was detected between the concentration of iron and psychomotor disorders.
Localization and translocation of mature miRNAs
Authors: Abaturov A.E. , Babуch V.L.
Published: November 2021

The scientific review shows the ways of nuclear import and export of miRNAs in the cell. The authors present a clear and accessible scheme of microRNA translocation in the cell. The article shows that the main site of localization in the cytoplasm of cells of the RISC complex and its components, including miRNAs, are processing P-cells. The authors cite the fact that Argonaute proteins — signature components of the effector complex of RISC RNA interference — are localized in mammalian P-bodies. It is shown that proteins of the karyopherin family mediate the translocation of miRISC into the cell nucleus. These proteins recognize nuclear localization sequences (NLS) in the amino acid sequences of proteins and actively transport these proteins through the pores of the cell’s nuclear membrane. It is emphasized that in addition to non-selective mechanisms of nuclear import of miRNAs, there are transport mechanisms that carry certain miRNAs across the cell membrane. Some miRNAs are presented, which are mainly localized in the nucleus of a certain type of cell. Scientists believe that much of the nucleus miRNA is concentrated in polysomes. Export of nuclear pool microRNA into the cytoplasm of the cell occurs with the help of export 1. Thus, in the cytoplasm of the cell, mature forms of microRNA accumulate, some of which are translocated to the cell nucleus or the extracellular space. Assembly of the miRISC complex is carried out in the cytoplasm of the cell, and only after the formation of the complex, it is imported into the cell nucleus. The spectrum of exosome-associated miRNAs can be a highly important diagnostic criterion for some nosologies, and exosomes containing certain miRNAs can be used for targeted therapy of specific diseases. To write the article, information was searched using databases Scopus, Web of Science, MedLine, PubMed, Google Scholar, EMBASE, Global Health, The Cochrane Library, CyberLeninka.

In this work, we present the general procedure for the robotic observations of the Transneptunian Automated Occultation Survey (TAOS II). The project aims to detect small TNOs (Transneptunian Objects) by serendipitous stellar occultations. To do so TAOS II will operate three 1.3 m telescopes equipped with CMOS cameras which are able to read about 10,000 stars in multiple subapertures at a 20 Hz cadence. At such rates, it will be possible to identify diffraction features in the lightcurves, helping us to estimate a distance and object size to each occultation event. TAOS II is installed in the Observatorio Astronómico Nacional in San Pedro Mártir, Ensenada, México (OAN-SPM). The site has good observing conditions, typically with around 260 useful nights per year. Here, we describe the different process to be performed in a typical observing night: system start up and shut down, monitoring observing conditions, acquisition of calibration images, field selection, pointing, camera synchronization, determination of aperture sizes and positions, and high speed image acquisition.

Published: November 2021

We present preliminary results from the Palomar Transient Factory (PTF) uniform sample of short period comets (SPCs) and long period comets (LPCs), captured between September 2009 and March 2013. We study their dynamical and physical properties in relation to their activity for a better understanding of cometary evolution. This observing campaign was part of PTF in its intermediate phase (iPTF) at the California Institute of Technology (Caltech). The photometric sample comprises more than 180 comets, which makes it one of the largest samples studied to-date. We present a new approach to identifying active comets that compares subtracted aperture magnitudes of comets with the distribution of stars of similar brightness in each image. In this paper, we present initial findings on cometary activity in relationship to their perihelion distances. We show differences between the distributions of the SPCs and that of the LPCs. As others predicted, it seems that a larger fraction of LPCs are found to be active at larger perihelia than for the SPCs. We look at ratios of active comets in different perihelia brackets and compare those to previous works and results. We do not discuss the statistical significance of our findings as this is still work in progress.

Published: November 2021

Abstract: PV systems are becoming more popular now a days, due to increase in the energy demand and it also reduces the environment pollution around the world. This paper proposes a reduced switches count of five-level H-bridge inverter with integrated boost converter in solar PV system. The proposed 5-level reduced switches count H-bridge MLI configuration requires less no.of power semiconductor devices compared to that of conventional MLI topology. In this paper INC MPPT control technique is used, which provides a duty ratio for controlling dc-dc boost converter and allowing the PV cells to operate more efficiently and extract maximum solar energy. The phase shifted sinusoidal pulse width modulation (PSCPWM) control technique is used for controlling the gating pulse of 5-level reduced switches H-bridge inverter. To improve the quality of PV based 5-level reduced switches h-bridge inverter output parameters mainly contribute switching losses and total harmonic distortion. The proposed model is modeled and simulated in MATLAB/SIMULINK software. Keywords: PV array, H-bridge multilevel inverter, boost converter, phase shifted PWM, maximum power point tracking (MPPT), incremental conductance, total harmonic distortion (THD).

Desde el institucionalismo histórico se describen las acciones desarrolladas por la Policía Nacional de Colombia en el año 2020 en el servicio de policía, con ocasión del escenario de emergencia sanitaria generado por la pandemia COVID 19, que cambió el entramado criminógeno y el comportamiento de actores criminales y el delito en el país. Por lo tanto, la policía utilizó un enfoque de policía proactiva y criminología táctica para la contención del crimen en Colombia, que se explica en este capítulo. Entre los principales resultados se destaca el uso de evidencia científica y la utilización de la criminología táctica como soporte de la planeación del servicio policial, para el diseño de acciones que estuvieron asociados con la disminución del homicidio en Colombia del 4,2%, evidenciando contención del repunte del delito como efecto de la reconfiguración del crimen en la coyuntura crítica del confinamiento. Asimismo, este capítulo puede ser un referente para los organismos de seguridad, que plantea una reflexión de las enseñanzas en la aplicación de un enfoque de policía proactiva en los cambios recientes del crimen durante el escenario de pandemia COVID-19.
COUNTEREXAMPLES: CHALLENGES FACED BY ELEMENTARY STUDENTS WHEN TESTING A CONJECTURE ABOUT THE RELATIONSHIP BETWEEN PERIMETER AND AREA
Authors: Widjaja Wanty , Vale Colleen
Published: November 2021

One pedagogical approach to challenge a persistent misconception is to get students to test a conjecture whereby they are confronted with the misconception. A common misconception about a ‘direct linear relationship’ between area and perimeter is well-documented. In this study, Year 4-6 students were presented with a conjecture that a rectangle with a larger perimeter will always have a larger area. Eighty-two (82) students’ written responses from three elementary schools in Victoria, Australia were analyzed. The findings revealed that Year 4-6 students could find multiple examples to support the conjecture but they struggled to find counterexamples to refute the conjecture. The findings underscored the importance of developing elementary school students’ capacity to construct counterexamples and recognize that it is sufficient to offer one counterexample in refuting a conjecture about all cases. Implications for ­teaching practice to support investigating and testing a conjecture are discussed.
High-tech law: concept, genesis and prospects
Authors: Bertovsky Lev V.
Published: November 2021

Relevance. The article considers the development of law as a regulator of public relations in correlation with emerging and applying various technologies by mankind. In the process of transition from low-tech to high-tech, society has experienced three industrial revolutions and is on the verge of the fourth. The article attempts to establish the stage of modern law development and the degree of its convergence with high technologies. The conclusion is made about the emergence of a new phenomenon - high-tech law, the inner side of which is application of high technologies to solve problems that appear in the process of law enforcement, and the outer side is regulation of public relations arising from their use. The purpose of the work is to substantiate the need for a systematic and evolutionary approach to personnel, technical and regulatory support for further development and functioning of high-tech law and to develop reasonable proposals for solving these problems. The materials for the research were scientific works of specialists in the field of philosophy, legal theory, psychology, technology, statistical data. The authors experience in organizing training of highly qualified specialists aimed at obtaining a set of competences in the field of law and high technologies has also contributed to this research. Methods. The results and conclusions are obtained on the basis of general scientific research methods: logical, systematic, sociological, as well as private-scientific and special: comparative-legal, formal-legal, interpretation, statistical, and some others. Results. The concept of high-tech law is substantiated and formulated, recommendations for its further technological and regulatory modernization are proposed, and a number of conclusions are made that determine the need to change the process of training legal personnel.
Administrative regulations as a type of public administration acts
Authors: Arzamasov Yuriy G. , Nazaykinskaya Varvara A.
Published: November 2021

The article examines a relatively new type of public administration acts for the Russian legal system - administrative regulations. Despite the widespread use of this type of act, its legal nature, features of the legal structure, and classification remain insufficiently studied, which determines the relevance of this study. The purpose of the study is to identify the specific characteristics of administrative regulations, allowing to classify them as a special tool for realisation of various public administration forms. Achieving this goal suggests analysis of regulatory legal acts, both Russian and foreign, as well as certain approaches to legal doctrine to determine the essence of administrative regulations, various public administration forms, and acts of public administration. Based on the analysis of theoretical and empirical data, the authors offer their definitions of acts of public administration, administrative regulations, and tools for realisation of public administration forms. In the process of research, the authors used a formal legal method that allows characterising the legal nature of administrative regulations, their role, and place in the system of acts of public administration, a comparative legal method to identify the general and the special when comparing domestic and foreign experience and general logical methods (analysis, synthesis, analogy).
Category of time limit in administrative procedural law
Authors: Beliakovich Elena V.
Published: November 2021

Administrative procedural law is full of numerous and varied procedural time limits which, as time-related categories, define the temporal boundaries of the administrative process and can act as an effective regulator of administrative procedural legal relations. The article examines the concept of time limit in administrative procedural law from the standpoint of integrativeness. It notes that the studied issue was not thoroughly elaborated in science, which appears to result from the young age of administrative procedural law as a separate branch. The research identifies substantial characteristics of the administrative procedural time limit. It reveals the temporal content of time limit in administrative procedural law. A conclusion is reached that the administrative procedural time limit results from the impact of temporal categories on the administrative procedural legal regulation when administrative cases are settled by a public administrative authority and a court. The administrative procedural time limit is recognised as a tool used for temporalizing the administrative process and aimed at ensuring the dynamism of administrative procedural activities through duration, speed, rhythm and cyclicity. The article identified the trend towards the legislative refinement of the administrative procedural time limits. In an integrative sense, the attributes inherent to the administrative procedural time limit reveal the versatility and rich inner content of the concept of time limit in administrative procedural law, which results from the legal synthesis of temporality and authoritative procedural activities of public administrative authorities and courts in settling administrative cases. The article proposed the definitions for the category of time limit in administrative procedural law both in a narrow and broad sense, as well as with an emphasis on the temporal side of the examined category.

Authors: Mubarok Faizul
Published: November 2021

Economic instability is a challenge for Islamic banks in channeling financing to various sectors including agriculture. This study aims to shed some light on the influence of economic indicators and the financing response to agriculture sector using monthly data from 2006 to 2020, including data from agriculture sector financing, interest rates, inflation, exchange rates, Islamic stock index, and composite stock index. This study employed Vector Error Correction Model (VECM) method. The results revealed that only interest rates and inflation affected Islamic bank financing in the short and long term period. Islamic bank financing in the agriculture sector reached the fastest stability when responding to exchange rate shocks. The results further showed that interest rates mostly influenced the level of diversity in Islamic bank financing in the agriculture sector. The results suggest that stakeholders need to play a crucial role in stabilizing economic turmoil to accelerate Islamic bank financing particularly in agriculture sector.

networks, artificial neural networks, support vector machines, decision
trees, k-nearest neighbors) to classify otoscopic images. Diagnostic
classes of interest: normal tympanic membrane, acute otitis media (AOM),
otitis media with effusion (OME), chronic otitis media (COM) with or
without perforation, cholesteatoma, and canal obstruction. Main Outcome
Measures: Accuracy to correctly classify otoscopic images compared to
otolaryngologists (ground-truth). The Quality Assessment of Diagnostic
Accuracy Studies Version 2 tool was used to assess the quality of
methodology and risk of bias. Results: Thirty-nine articles were
included. Algorithms achieved 90.7% (95%CI: 90.1 – 91.3%) accuracy
to difference between normal or abnormal otoscopy images in 14 studies.
The most common multi-classification algorithm (3 or more diagnostic
classes) achieved 97.6% (95%CI: 97.3.- 97.9%) accuracy to
differentiate between normal, AOM and OME in 3 studies. Compared to
manual classification, AI algorithms outperformed human assessors to
classify otoscopy images achieving 93.4% (95%CI: 90.5 – 96.4%)
versus 73.2% (95%CI: 67.9 – 78.5%) accuracy in 3 studies.
Convolutional neural networks achieved the highest accuracy compared to
other classification methods. Conclusion: AI can classify ear disease
from otoscopy. A concerted effort is required to establish a
comprehensive and reliable otoscopy database for algorithm training. An
AI-supported otoscopy system may assist health care workers, trainees,
and primary care practitioners with less otology experience identify ear
disease.
Dynamic interspecies interactions and robustness in a four-species model biofilm

Published: November 2021

Interspecific interactions within biofilms determine relative species
abundance, growth dynamics, community resilience, and success or failure
of invasion by an extraneous organism. However, deciphering
interspecific interactions and assessing their contribution to biofilm
properties and function remain a challenge. Here, we describe the
constitution of a model biofilm composed of four bacterial species
belonging to four different genera (Rhodocyclus sp., Pseudomonas
fluorescens, Kocuria varians, and Bacillus cereus), derived from a
biofilm isolated from an industrial milk pasteurization unit. We
demonstrate that the growth dynamics and equilibrium composition of this
biofilm are highly reproducible. Based on its equilibrium composition,
we show that the establishment of this 4-species biofilm is highly
robust against initial, transient perturbations but less so towards
continuous perturbations. By comparing biofilms formed from different
numbers and combinations of the constituent species and by fitting a
growth model to the experimental data, we reveal a network of dynamic,
positive, and negative interactions that determine the final composition
of the biofilm. Furthermore, we reveal that the molecular determinant of
one negative interaction is the thiocillin I synthesized by the B.
cereus strain, and demonstrate its importance for species distribution
and its impact on robustness by mutational analysis of the biofilm
ecosystem.

Published: November 2021

The complete life cycle of O. ferruginea is described for the first time, represent the first complete life cycle described for an odonate in Mexico. The 17 larval instars obtained are described and illustrated in detail, from prolarva through F-0. Two egg batches of different females were obtained in the field and were subsequently reared in the laboratory. Eggs and larvae of the batches were raised under 26°C controlled temperature conditions until they reached instars F-6 and F-5. An extra collection of wild organisms was made in order to complete the life cycle from F-5. Only four of the wild larvae managed to complete the last five missing larval instars at 30°C. Larvae of the youngest instars (F-15 to F-8) were fed nauplii of Artemia franciscana, while F-7 to F-0 were fed larvae of Culicidae and Chironomidae. Larval life cycle from F-0 to F-16 lasted average of 186 days.
