Objective: The objective of this study was to assess the availability and quality of FP services in health facilities (HFs) on Idjwi Island in the eastern Democratic Republic of the Congo (DRC). Methods: From March 1 to 31, 2022, a descriptive cross-sectional study was conducted in several HFs on Idjwi Island. Identified 31 HFs have been comprehensively included. Data were collected through interviews, literature reviews, and observations, guided by a questionnaire. Results: Of the 31 HFs included, 29 (93.6%) of them provided FP services on an availability basis, of which 27.6% (8/29) met the criteria for high-quality services. The most widely available methods were male condoms, combined oral contraceptive pills, and progestin-only injectable contraceptives. Conclusion: The availability of FP services in HFs on Idjwi Island remains high but their quality is low. To improve access to and use of FP, efforts should focus on improving quality in this rural part of the country.
ASPECTS OF DISTANCE LEARNING FOR MEDICAL STUDENTS IN THE CONDITIONS OF THE COVID-19 PANDEMIC
Authors:   Prof. V.F. Voino-Yasenetsky Krasnoyarsk State Medical University (Krasnoyarsk, Russia), Vereshchagina T.D.
Published: May 2022

Statement of the problem. The article summarizes the author’s experience in the introduction and widespread use of interactive teaching methods in distance education during the COVID-19 pandemic. The presented methods are designed to identify the pros and cons of distance learning, to highlight the problems that arise in the so-called “remote” and partially distance learning. Medical education, like no other, is undergoing major changes during the pandemic. Special difficulties are created by the impossibility of students’ presence at clinical bases, most of which are repurposed for a new coronavirus infection and the absence of a hospital environment typical for teaching, providing students with direct contact with the patient. The purpose of the article is to describe the methods of distance learning used in the conditions of the COVID-19 pandemic for recommendations to fellow teachers of higher education. The methodology is based on the use of system-activity and personality-oriented approaches to training; the introduction of interactive simulators, simulators and virtual simulators on remote platforms. The study of the digestibility and survival of knowledge is carried out on the basis of the analysis of the protocols of passing tasks, as well as the results of tests and exams. Research results. The use of interactive techniques in the practice of teaching medical students has shown their high effectiveness in the conditions of a pandemic. Some of the methods described in the article were successfully used earlier, in the “pre-epidemic era”, others arose in connection with the epidemiological situation, but it was their application that prevented the collapse in education, advanced the teaching abilities of teachers and brought education closer to the modern perception of students. Conclusion. The methods and forms of teaching proposed in the article, innovations, are certainly debatable and require improvement in the process of practical teaching.

Statement of the problem. The period of preschool age is a necessary and significant period for the beginning of the formation of the volitional aspect of the personality. This predetermines the interest in studying this issue. The relevance of studying the development of volitional qualities of frequently and chronically ill children is explained by an increase in the proportion of somatically sick children and becomes especially important in connection with the search for effective ways of raising these children. The purpose of this article is to study the systemic characteristics of the development of volitional qualities in healthy and frequently and chronically ill children in a comparative aspect. The methodological basis of the study includes the activity approach, cultural and historical concept of the development of higher mental functions, and the theory of internalization in the formation of mental functions. Theoretical research methods, empirical methods, and methods of statistical analysis were used. Research results. The study made it possible to reveal: the peculiarities of the development of volitional qualities in the group of healthy children and in the group of frequently and chronically ill children; the dynamics of the development of individual qualities; heterogeneity in the nature of the development of individual volitional qualities. The article provides a discussion of the revealed features in the development of volitional qualities of frequently and chronically ill children. Conclusion. The results allow us to assess the formation of volitional qualities in healthy and somatically sick contemporary preschool children. The presented information helps to build pedagogical work on the formation of volitional qualities in preschool children and to provide effective psychological and pedagogical assistance to children and their parents.
CONSECUTIVE TAXIS IN THE ASPECT OF INTERCATEGORIAL INTERACTION (BASED ON THE MATERIAL OF DIFFERENT-STRUCTURED LANGUAGES)
Authors:   Novosibirsk  State  Pedagogical  University  (Novosibirsk,  Russia), Аrhipova I.V.
Published: May 2022

Statement of the problem. Due to the lack of coverage of the issue of intercategorial interaction of various functional-semantic categories, this problem remains the most relevant today. The focus of our research is the problem of intercategorial inclusion of the functional-semantic category of taxis and the category of consecutivity. Intercategorial inclusion of these categories determines the constitution of consecutive-taxis semantic syncretic complexes and the actualization of consecutive-taxis categorial situations of simultaneity in statements with monotaxis prepositions of consecutive semantics. The purpose of this article is to describe the actualization of consecutive-taxis categorial situations of simultaneity in different-structured languages: German, English, Dutch, Russian, and Polish. Methodology (materials and methods). The material was the statements of the German, Dutch, English, Russian, and Polish languages with monotaxic prepositions of the consecutive semantics infolge, ingevolge, krachtens, wskutek, w skutku, skutkiem, na skutek, w wyniku, w efekcie, w rezultaci, вследствие, в результате. The main methods used were the following: continuous sampling, hypothetical-deductive, inductive, and descriptive methods, classification method, as well as the method of synthesis and interpretation of linguistic material. Research results. It was found out that German, English, Dutch, Polish, and Russian statements with monotaxis prepositions of the consecutive semantics infolge, ingevolge, krachtens, wskutek, w skutku, skutkiem, na skutek, w wyniku, w efekcie, w rezultaci, вследствие, в результате, represent consequently taxis semantic syncretic complexes of simultaneity. They actualize consecutive-taxis categorical situations of simultaneity. Monotaxis prepositions of consecutive semantics act as markers of consecutive-taxis categorial situations of simultaneity. Deverbatives in combination with consecutive prepositions act as taxis actualizers.

ARCHAIC WORDS IN THE NOVEL “THE LORD OF THE RINGS: THE FELLOWSHIP OF THE RING” AS AN ELEMENT OF J.R.R TOLKIEN’S INDIVIDUAL STYLE
Authors:   Adyghe State University (Maykop, Adyghe Republic,  Russia), Berestneva A.V.
Published: May 2022

Statement of the problem. The vocabulary of a particular language is constantly updated, getting rid of redundant words, and simultaneously, enriching with new lexical units. The process of word obsolescence is a complex phenomenon, the result of which may be its gradual disappearance. Apart from sporadic cases of reactivation of passive vocabulary, most of the words from the obsolete vocabulary are gradually forgotten, eventually becoming completely incomprehensible to native speakers. Archaic words belong to the field of vocabulary, which is characterized by mobility and changeable sphere of use in any language. The most vivid manifestation of author’s style is in deviation from the literary norm of the language when the writer actively searches for the new linguistic forms or reinterprets archaic ones. One of the urgent problems in modern linguistics is the writer’s influence on the language he uses as the most important element of his individual style. The language of a literary work as a way of conveying content, is not only correlated, but also connected with this content; the lexicon depends on the content and on the author’s attitude towards it. The purpose of the article is to identify the role of archaisms in the formation of the individual J.R.R. Tolkien’s style on the example of the novel “The Lord of the Rings: The Fellowship of the Ring”. Methodology is as follows: method of linguistic description, component analysis method, methods of lexicographic and contextual analysis. Conclusion. The modern trend of studying individual style of a writer is based on the principle that every literary work has certain specific features which characterize the writer’s style. The analysis of the language material reveals the fact that J. R. R. Tolkien’s individual style dictionary includes a large number of obsolete words as a hallmark of his individual style. The suggested passages clearly show how the writer uses morphological features in combination with poetic and archaic vocabulary to model the represented reality. The motivated selection of certain lexical units is dictated by the content and genre of the work and includes the use of archaizing syntactic structures, the entire spectrum of obsolete vocabulary, poetic words, author’s neologisms.

Authors: Ilma Mughniatul , Herdiana Vicky Fitriani
Published: May 2022

Hand sanitizer could help clean one’s hands from germs and viruses, and thus, in a location where no handwashing is available, they could use hand sanitizer to clean their hands. Making hand sanitizer is very simple, and we could use plants found in one’s garden or yard. Limes and betels thrive in the garden owned by the Women's Farmer Group in Mojorejo Village, Jetis, Ponorogo Regency. These plants can be used to make hand sanitizer. However, the members of KWT had not known how to process them into hand sanitizer. This activity aimed to provide training for making hand sanitizer using natural ingredients picked from the KWT’s garden. As an alternative, we also trained the members of KWT about how to make hand sanitizer from artificial ingredients. We employed Asset Based Community Development (ABCD) method, which involves eight members of KWK in the village. We held an FGD to find the resources they had, and during the training, we demonstrated the procedures for making hand sanitizer. After the training, we also provided one-onone mentoring in making hand sanitizer. They made several kinds of hand sanitizer using natural and artificial ingredients. We interviewed two members of KWT after the training. They claimed that this activity had increased their knowledge about how to make use of the natural ingredients found in the garden, and that by making hand sanitizer by themselves, they could reduce their expenses.

Published: May 2022

One problem faced by the community in Sukamakmur Village, Ajung District, East Java, is that its youth groups do not have a program to improve the community welfare. Another issue is the lack of public knowledge regarding the use of potential resources, including water resources. The newly established BUMDes and youth organization seem not to have any business programs, which has become an obstacle to the efforts to improve the welfare of the rural community. To address these problems, a community service program was conducted to assist the youth groups, karang taruna, by empowering them and developing agro-sociopreneurship. Given the abundant water resources, they can be used to apply the biofloc technology for catfish farming. The activities in the program included needs analysis using the ABCD analysis of the FGD sessions, education on agrosociopreneurship, training, monitoring, and evaluation. The result showed that through the agrosociopreneurship mentorship, (i) as many as 33% of karang taruna members and livestock farmers attempted to engage in agro-sociopreneurship and (ii) livestock farmers have been able to apply biofloc technology in catfish farming.
Thirteen-year long-term follow-up in a rare case of anaplastic astroblastoma: What makes the difference?
Authors: Allison Callum Martin , Scoones David , Batra Arun , Sinclair Georges
Published: May 2022

Background:

Astroblastomas are uncommon neuroepithelial tumors of the central nervous system with a distinct, yet, controversial radiological, histological, and molecular profile. Debatable differences between low- and high-grade astroblastoma have been reported in the medical literature; indeed, despite the increasing relevance of molecular genetic profiling in the realm of astroblastoma, its application is still in its early stages. As a result, the diagnostic criteria for astroblastoma remain undecided with yet no real consensus on the most ideal management.

Case Description:

This report describes a case of astroblastoma diagnosed 13 years ago in a young woman who despite six episodes of recurrence, transformation, and progression was able to retain a perfomace status of 0 by World Health Organization standard, throughout.

Conclusion:

This report discusses the clinical, radiological, histological features, and management of this rare tumor with an extraordinarily long survival, with an aim to strengthen the literature on management options. To the best of our knowledge, this is the longest surviving case of anaplastic astroblastoma reported in the available medical literature.

1955’de Kuznets tarafından büyüme ve gelir dağılımı arasındaki ilişki ortaya konulmuş, bu ilişki zamanla farklı alanlara da uygulanmıştır. 1990’lı yılların başında çevre ile ekonomik büyüme arasında güçlü bir ilişkinin olduğu anlaşılmış ve Çevresel Kuznets Eğrisi yaklaşımı ileri sürülmüştür. İzleyen süreçte çevre kirliliğini temsil eden birçok değişken ayrı ayrı modellenerek Çevresel Kuznets Eğrisi test edilmiş ve çeşitli Kuznets Eğrileri literatüre kazandırılmıştır. Son yıllarda bunlara bir yenisi eklenerek Malzeme Kuznets Eğrisi yaklaşımı literatürde yer almaya başlamıştır. Malzeme Kuznets Eğrisi yaklaşımı malzeme ayak izi ile kişi başına gayri safi yurtiçi hasıla arasında Ters U şeklinde bir ilişki olduğunu ileri sürmektedir. Bu çalışmada Malzeme Kuznets Eğrisi yaklaşımının geçerliliğinin test edilmesi amaçlanmıştır. Bu amaçla G-7 ülkelerinin 1990-2016 dönemi verilerinden yararlanılmıştır. Modelin oluşturulmasında malzeme ayak izi değişkeni bağımlı değişken olarak ele alınarak malzeme kullanımına yönelik çevre kirlenmeleri toplu bir şekilde değerlendirilmiştir. Kişi başına GSYİH, kişi başına GSYİH2 ve kişi başına GSYİH3 seçilen bağımsız değişkenlerdir. Panel Durbin Hausman eşbütünleşme testi sonucunda değişkenler arasında Kuznets’in belirttiği gibi bir ilişki olmadığı tespit edilmiş ve böylelikle çalışma kapsamında Malzeme Kuznets Eğrisi yaklaşımı reddedilmiştir.

Authors: TURAN Damla , NARİN Müslüme
Published: May 2022

Yenilik, ekonomik büyümenin en önemli tetikleyicisidir. Ancak yenilik faaliyetlerinin riskli ve maliyetli olması yüzünden, yeniliğin finansmanı ekonomik büyümenin önündeki önemli engellerden birini oluşturmaktadır. Bu yüzden yenilik faaliyetlerini finanse etmek üzere birçok yöntem geliştirilmiştir. Geleneksel finansman yöntemleri çoğu zaman ya yetersiz kalmakta ya da uygulamada sıkıntılar içermektedir. Bundan dolayı tüm dünyada yenilik finansmanı için yeni ve alternatif yöntemler geliştirilmiştir. Yeniliğin finansmanı için geliştirilen bu yeni yöntemlerden en sık kullanılanları melek yatırımcılık, girişim (risk) sermayesi ve kitlesel fonlamadır. Bu çalışmada, yeniliğin finansmanında Türkiye’de de son yıllarda artan oranda kullanılan bu yöntemlerin uygulamaları üzerine bir değerlendirme sunulmuştur. Yeniliğin finansmanına yönelik bu yöntemler her ne kadar son yıllarda Türkiye’de de yaygınlaşmaya başlasa da yenilik potansiyeli açısından yeterli görülmemektedir. Bu nedenle Türkiye’de melek yatırımcılık, girişim sermayesi ve kitlesel fonlamanın geliştirilmesi ve yaygınlaştırılması için uygulanan politikalar artırılarak devam ettirilmelidir. Bu çalışmanın amacı, Türkiye’de de gittikçe yaygın kullanılan yeniliğin finansman yöntemlerinin uygulamaları üzerine bir değerlendirme yapmaktır. Bu kapsamda çalışmada öncelikle yenilik ve ekonomik büyüme ilişkisi üzerinde durulmuş, ardından yeniliğin finansmanına değinilmiş, son olarak da alternatif finansman yöntemleri hakkında bilgi verilerek Türkiye açısından bir karşılaştırma yapılmıştır.
Novel Mass Spectrometry Methods in Flavour Analysis
Authors: Fay Laurent B. , Yeretzian Chahan , Blank Imre
Published: May 2022

Flavour research is a demanding domain in terms of analytical methodology as key odorants usually occur in trace amounts, often embedded in extracts containing volatile compounds at much higher concentrations. Since its early days, GC-MS has been a key tool in flavour laboratories enabling
characterisation of thousands of volatile components in food products. However, as flavour chemists delve deeper into the understanding of flavour generation and delivery, there is a need for more powerful methodologies adapted to their specific needs. This paper will present two techniques
that allow flavour separation and characterisation, namely GC-TOFMS and MS/MS. Moreover, APCI-MS, PTR-MS and REMPI-TOFMS will be discussed as they enable direct investigation of volatile compounds without any chromatographic step, thus studying release of flavour compounds during food processing
or food consumption.
Disorder and Motion in Crystal Structures: Nuisance and Opportunities
Authors: Bürgi Hans-Beat , Weber Thomas
Published: May 2022

Conventional structure analysis averages the structure of an entire crystal into a single unit cell. If there is disorder and thermal motion, this averaging obscures information on local structure, intermolecular interactions and molecular dynamics. Nonetheless structural detail at
the molecular and supramolecular level can be retrieved even for heavily disordered molecular materials by analyzing their diffuse scattering. Molecular dynamics can be elucidated and distinguished from disorder on the basis of atomic displacement parameters (ADPs) determined over a range
of temperatures from conventional structure analyses. Such studies are now becoming feasible for molecular crystals through improved experimental techniques, faster computers and new algorithms.
Exploration of Structure-Property Relationships
Authors: Schreuer Jürgen
Published: May 2022

Electrostriction and elasticity provide highly sensitive probes for the exploration of structure-property relationships. With the aid of modern high-resolution capacitive dilatometers reliable linear and quadratic electrostrictive constants can be determined. The unusual thickness dependence of the converse piezoelectric effect in α-quartz and the electrostrictive behavior of the alkali halides are presented as examples. The close correlations between elastic properties and crystal structures are reflected by several heuristic and empirical rules. Resonant ultrasound spectroscopy (RUS) belongs to the most promising methods for the determination of elastic constants in the acoustic frequency regime. The potential of RUS for the simultaneous investigation of elastic and electrostrictive properties including electromechanical coupling effects is discussed.
Cobalt-Catalyzed Hydrogenation Reactions Enabled by Ligand-Based Storage of Dihydrogen
Authors: Anferov Sophie , Filatov Alexander , Anderson John
Published: May 2022

The use of supporting ligands which can store either protons or electrons has emerged as a powerful strategy in catalysis. While these strategies are potent individually, natural systems mediate remarkable transformations by combining storage of both protons and electrons in the secondary coordination sphere. As such, there has been recent interest in using this strategy to enable fundamentally new transformations. Furthermore, outsourcing H-atom or hydrogen storage to ancillary ligands can also enable new mechanistic pathways and thereby selectivity. Here we describe the application of this strategy to facilitate radical reactivity in Co-based hydrogenation catalysis. Metalation of previously reported dihydrazonopyrrole ligands with Co results in paramagnetic complexes which are best described as having Co(II) oxidation states. These complexes catalytically hydrogenate olefins with low catalyst loadings under mild conditions (1 atm H2, 23 °C). Mechanistic, spectroscopic, and computational investigations indicate that this system goes through a radical hydrogen-atom transfer (HAT) type pathway that is distinct from classic organometallic mechanisms and is supported by the ability of the ligand to store H2. These results show how ancillary ligands can facilitate efficient catalysis and furthermore how classic organometallic mechanisms for catalysis can be altered by the secondary coordination sphere.

La tecnológía es un conjunto de conocimiento que permiten saber como operar industrialmente para producir productos o servicios competitivos en el mercado.

La tecnología es un recurso susceptible a ser administrado, como tal, es una mercancía que puede ser comercializada.

Toda innovación o cambio tecnológico procede únicamente de dos fuentes:  de la investigación o de la transferencia (compra de la tecnología.

Se tiene la idea errada de que el acceso a la información tecnológica es difícil, debido al secreto industrial y a los derechos otorgados por las patentes de invención. Pero en nuestro pais, ITINTEC posee una Base de Datos de 8000 patentes registradas en el Perú y a través de la vía satélite,25000 patentes más (Base de Datos de Madrid España), a las cuales pueden y deben accesar los industriales y los investigadores, pues son la fuente de información técnica más completa, que están protegidas legalmente, pero que, una vez vencida su vigencia, pueden explotarse libremente.

La relación entre la calidad y empleo del carbón en el Perú
Authors: Dunin-Borkowski Estanislao
Published: May 2022

La minería e industria del carbón en el Perú, a pesar de tener un siglo de historia, se encuentran en la etapa inicial de su desarrollo, en la cual hay que forjar nuevos métodos y procedimientos.

Los sucesivos gobiernos han destinado grandes recursos para la promoción del carbón, pero no se han preocupado suficientemente por el reconocimiento de los yacimientos e ignoraron la preparación de cuadros técnicos y el equipamiento de los laboratorios. Lo cierto es que el Perú posee numerosos yacimientos de carbón que virtualmente no se aprovechan.

Sin embargo, estamos importando carbones y sus derivados, lo cual representa una salida de divisas.

¿Se puede aprovechar el gran potencial carbonífero peruano? ¿Podemos sustituir el carbón importado por el nacional?.

Problemática de la antracita en el Perú
Authors: Dunin-Borkowski Estanislao
Published: May 2022

El Perú dispone de una gran potencial de antracitas en el oeste del páis entre los paralelos 6° 30'S y 11° 30'S. Este potencial no se pudo aprobechar debido a la confusa situación legal  de los campos carboníferos y a la falta de mercado. Con la nueva ley de Minería, se espera que la situación cambie quedando como reto la creación del mercado adecuado. Se espera que, estando asegurada la oferta de antracita con calidad uniforme y aceptable y a un precio razonable, muchos usuarios potenciales sedecidirán a adaptar las instalaciones para uso. Algo muy importante para ampliar el mercado será la preparación y purificación mecánica de la antracita. 

La antracita nacional podrá emplearse para reducción directa de los pellets de óxidos de hierro de Marcona, carboeléctricas que abastecerán el sistema interconectado, generación del vapor en la industria, fabricas de cemento, etc. La antracita, para ser competitiva debe tener un precio considerablemente inferior por caloría. en el lugar de consumo, que el petróleo y sus derivados. Para conseguir esto se necesita bajar los costos por economías de escala.

La antracita puede, también utilizarse para incrementar el valor de los recursos locales vecinos como en la elaboración del cemento, de las calizas, cerámica, industrialización de yeso o la sustitución de la quema del bagazo en ls ingenios azucareros para emplearlo con mayor provecho en la fabricación del papel.

Las primeras investigaciones arqueológicas y las frases de Cieza de León nos dieron la segridad que Chilca habia sido un paaíso agrícola en el perído preinca, durante el incario y aún después de éste, sin embargo, una paulatina desertificación es la consecuencia del largo coloniaje y la era republicana por el descuido y la depredación de la floresta existente en sus lomas, al cambiar la civilación criolla el método de vida y necesitar la leña como combustibl para cubrir las necesidades de la civilización impuesta de tres coidas caliente diarias, depredación de los montes para el servicio de leña para la ciudad, y la derivación de la importancia del trabajo hacia la explotación minera y de servicio devino en el descuido y la desaparición de la foresta de nuestros bosques costeeeros, fuenes de la atracción del agua de nieblas y la consiguiene desertificación de la zona.

The risk of developing cardiovascular disease in bipolar disorder. Biological factors and therapy
Authors: Mosolov Sergey N. , Fedorova Elizaveta Yu.
Published: May 2022

Background. Bipolar disorder (BD) is one of the most common mental disorders characterized by alternating episodes of mania/hypomania and depression, as well as the possibility of developing mixed conditions. Correct and timely diagnosis of BD is important due to the presence of a high suicidal risk and a high predisposition to the development of cardiovascular disease (CVD). The risk of CVD is higher in ВD than in other mental disorders.
Materials and methods. A sample assessment was made of current studies focusing on the vascular-bipolar link. The search was carried out in the PubMed and eLIBRARY databases for the following keywords: bipolar disorder, psychopharmacology, cardiovascular disease, biological mediators.
Results. There are several biological factors which explain the close association and common pathogenetic mechanisms of BD and CVD. The most interesting of them are inflammation, oxidative stress, and brain-derived neurotrophic factor. Neuroimaging methods have shown similar structural brain changes in people with BD and with CVD. There is some evidence of the efficacy of statins and angiotensin-converting enzyme inhibitors in reducing cardio-vascular risk factors in BD patients.
Conclusion. The predisposition of patients of BD to CVD is beyond doubt. It is necessary to consider the peculiarities of the course of BD and conduct active monitoring and preventive measures to reduce the risk of developing life-threatening CVDs. Further research focused on the pathogenetic relationship between BD and CVD could provide more insight into this area.

Aim. To compare efficiency and specific features of transthyretin amyloid staining by different histological dyes and thus to assess their suitability for diagnostic purposes.
Materials and methods. Samples of left and right heart ventricles were taken from patients over 70 years-old of both genders (n=10) with immunohistochemically verified transthyretin amyloidosis (ATTR). All samples were stained with Congo red, Alcian blue, toluidine blue and methylene violet.
Results. Specificity and sensitivity of Congo red staining was comparable to those of immunohistochemical staining. For verification of amyloid presence after Congo red staining one could use fluorescent microscopy instead of polarization microscopy. It allows a more accurate diagnosis of amyloidosis. Confocal microscopy with spectral unmixing improves detection sensitivity of amyloid by elimination of background fluorescence of muscle tissue and autofluorescence of lipofuscin. Alcian blue staining gives the same result as Congo red. In addition, its less labor-intensive and free of false-positive and false-negative results caused by final processing of slide preparation. Toluidine blue and methylene violet develop metachromatic staining upon binding to transthyretin fibrils, likely due to specific biochemical features of these fibrils.
Conclusion. The most reliable method for histochemical diagnosis of ATTR is the Congo red staining with subsequent analysis using fluorescence or confocal microscopy. For diagnostic screening, the use of Sodium sulphate-Alcian blue staining method is highly promising. Metachromatic stains are less effective for ATTR diagnosis.

Published: May 2022

Non-compact right ventricular myocardium is a rare type of cardiomyopathy, it usually results from arrested myocardial development during embryogenesis. This disease can be characterized by excessive prominent trabeculations and deep inter-trabecular recesses in the ventricular wall. It might be a component of biventricular non-compact cardiomyopathy or an isolated form. The article presents a review of the literature on the clinic and radiation diagnostics of non-compact right ventricular myocardium with the presentation of the issues of differential diagnosis.
Evolution of facial prosthetics: Conceptual history and biotechnological perspectives

Published: May 2022

The reconstruction of cephalic defect and more precisely from the face is not a recent issue. Indeed, the use of facial masks in a symbolic perspective was reported in ancient Egypt. Few references to facial prostheses are then found. It is really only with the work of the French surgeon Ambroise Paré that the first surgical techniques concerning facial epithetics are described. Techniques and materials tend to evolve over the centuries. But then came WWI, which marked a major turning point and brought to light the broken faces and the impact of maxillofacial trauma. Rehabilitation became a major issue in society. The war was a driving force for change from both a surgical and prosthetic point of view, revealing in particular such brilliant designers as the American sculptor Anna Coleman Ladd. Today, the profession is undergoing a major upheaval, linked to the growing development of biotechnological constructions. This historical review aims to retrace the evolution of the rehabilitation of facial substance loss over the ages and to outline the prospects for the foreseeable future.

Published: May 2022

This article focuses on the impact of the financial sector on inclusive, sustainable development. The paper aims to study the impact of the fintech industry and financial inclusion on the development of the financial system to achieve the UN SDGs. We discussed various approaches to the content of the “fintech” and “ecosystem” terms and offered an interpretation of the term “financial inclusion”. We used comparative and system analysis methods to study the publications of many authors who found that a developed and inclusive financial system affects the reduction of poverty and inequality, welfare and employment, consumer market, economic growth, sustainable development, etc. At the same time, we showed variants of the relationship between increased access to financial services and financial stability, which can both be positive and negative. The state of the financial services market in Russia, which ranks high in various ratings in terms of financial inclusion, is described in detail. Further, we considered the barriers to the growth of financial inclusion in Russia and ways to overcome them. The practical significance of the work lies in the possibility of its use in the development of key areas of financial market development. Next, more attention needs to be paid to regulatory influences on consumer behaviour in selecting services and their providers.
