Authors: Зенкин К.В.
Published: November 2022

В статье рассматриваются исторические формы процессуальности музыкальной материи, при этом делается акцент на понимании звука как процесса в композициях 2-й половины XX в., главным образом, в творчестве Карлхайнца Штокхаузена и его современников. Проводится классификация основных типов процессуальности звука, в том числе в композициях, реализующих принципы «момент-формы» и «процессуальной музыки». Процессуальность звуковой материи рассматривается в связи с явлением музыкальной информации, обретшей в новейшей музыке особые формы и выразительный смысл.

The article considers historic forms of the process character of the music substance, focusing on interpreting the sound as a process in the works of the second half of the 20 th century, mainly, in the oeuvre of Karlheinz Stockhausen and his contemporaries. The major types of the process character of the sound, including those in compositions which implement the principles of “moment form” and “process music”, are categorized. The process character of the sound substance are analyzed with regard to the phenomenon of musical information, which has acquired peculiar forms and expressive meaning in modern music.

Electrolytic Synthesis of White Phosphorus is Promoted in Oxide-Deficient Molten Salts
Authors: Melville Jonathan , Licini Andrew , Surendranath Yogesh
Published: November 2022

Elemental white phosphorus (P4) is a key feedstock for the entire phosphorus-derived chemicals industry, spanning everything from herbi-cides to food additives. The electrochemical reduction of phosphate salts could enable the sustainable production of P4; however, such electrosynthesis requires the cleavage of strong, inert P—O bonds. By analogy to the promotion of bond activation in aqueous electrolytes with high proton activity (Brønsted-Lowry acidity), we show that low oxide anion activity (Lux-Flood acidity) enhances P—O bond activa-tion in molten salt electrolytes. We develop electroanalytical tools to quantify the oxide dependence of phosphate reduction, and find that Lux acidic phosphoryl anhydride linkages enable selective, high-efficiency electrosynthesis of P4 at a yield of 95% faradaic efficiency. These fundamental studies provide a foundation that may enable the development of low-carbon alternatives to legacy carbothermal synthesis of P4.
Visible Light-induced regioselective bifunctionalization of α-olefin; Development of one-pot photo-synthesis of C3-substituted dihydrobenzofurans
Authors: Maejima Saki , Yamaguchi Eiji , Itoh Akichika
Published: November 2022

A method for the catalytic regioselective synthesis of C3-substituted dihydrobenzofurans (DHBs) via [2+2] photocycloaddition of alkene and p-benzoquinone is developed. This method realizes the rapid synthesis of DHBs with readily available substrates and simple reaction conditions by using Lewis acid B(C6F5)3 and Lewis base P(o-tol)3 as a catalyst in combination with the classical Paternò–Büchi reaction. This reaction is of interest in terms of bifunctionalization by formal [2+3] cycloaddition of olefins and applies to a wide range of a-olefins.
A π-Conjugated Covalent Organic Framework Enables Interlocked Nickel/Photoredox Catalysis for Light-Harvesting Cross-Coupling Reactions
Authors: Jati Ayan , Dam Suranjana , Kumar Shekhar , Kumar Kundan , Maji Biplab
Published: November 2022

Covalent organic frameworks (COF) is an outstanding manifesto for heterogeneous photocatalysis. Herein, we synthesized a pyrene-based two-dimensional C=C linked π-conjugated COF via Knoevenagel condensation and anchored Ni(II)-center through bipyridine moieties. Instead of traditional dual metallaphotoredox catalysis, the mono-metal decorated Ni@Bpy-sp2C-COF interlocked the catalysis mediated by light and the transition metal. Under light irradiation, enhanced energy and electron transfer in the COF backbone, as delineated by the photoluminescence, electrochemical, and control experiments, expedited the excitation of Ni centers to efficiently catalyzes diverse photocatalytic C–X (X = B, C, N, O, P, S) cross-coupling reactions with efficiencies orders of magnitude higher than its homogeneous controls. The COF catalyst tolerated a diverse range of coupling partners having various steric and electronic properties under these conditions delivering the products with up to 99% yields. A large number of functional groups were also accommodated for the model reaction. Some reactions were performed on a gram scale and were applied to diversify pharmaceuticals and complex molecules to demonstrate the synthetic utility. The Ni@Bpy-sp2C-COF catalyst could be recovered and reused for several cycles without significant loss in catalytic activities.

Published: November 2022

To arrive at an understanding about the view and attitudes of pregnant women regarding late termination of pregnancy after prenatal  diagnosis of a severe fetal anomaly. A semi-structured questionnaire based prospective descriptive study was conducted from January  2022 to September 2022 in Obstetrics and Gynecology department of Saveetha Medical College and Hospital, Thandalam. 16 pregnant  women with severe fetal anomalies detected after 23 weeks were included. All the women were counselled about the type and lethality of the anomaly including management option. Informed consent was obtained from all the patients and ethical approval was obtained. A total of 16 women with congenital anomalies in fetus detected after 23 weeks of gestation over 8 months of the study period were  included in the study. All the participants were properly counselled and given adequate time to make the decision. Among which 11  decided to terminate the pregnancy and 5 continued. All 11 who opted for termination of pregnancy was joint decision by the family. 5  women continued their pregnancy. Reasons to continue the pregnancy were praying that baby will born normal (n=1), hoping that  surgery can correct the abnormality (n=3) and wanting to see the baby (n=1). This study shows that women who are pregnant with  serious fetal anomalies have a range of opinions and attitudes regarding termination. To compare with initial decision making larger  follow-up studies will be necessary to see whether patient’s perspective changes over time.
Vocational education and training reform in Aotearoa New Zealand
Authors: Maurice-Takerei Lisa , Anderson Helen
Published: November 2022

The Education and Training Act 2020 provides an opportunity to transform the Vocational Education and Training (VET) system in Aotearoa New Zealand to ensure participants are successfully prepared for participation in the current and future workforce. The authors of this paper discuss current reforms in the VET system beyond the changing of components and the assignation of requisite tasks. While change to processes and systems can have an impact on VET outcomes, the kind of change that transforms individual lives and life chances depends on the decision-making and approaches made possible only by individuals ‘at the coalface.’ Indeed, changes to training programmes and processes alone cannot give effect to improved outcomes. The authors suggest that it is educators, the often unnamed and invisible workforce that will provide the basis for transformational VET based change. The VET workforce who daily mediate training programmes and curriculum as educators, facilitators, trainers, instructors and teachers are central to the transformation of VET. Indeed, the most challenging and complex of changes within the Review of Vocational Education (RoVE) is one that is not yet accounted for or named – the VET education workforce. The authors call for a recognition of educators in VET and an acknowledgement of the centrality of their work in change. A case for planning and strategy that provides direction for the education and training workforce to build their knowledge and capability for a new VET is presented, without which the opportunity for transformational reform is at risk of being lost to componentry change.
LA REVOCATORIA DE AUTORIDADES REGIONALES Y MUNICIPALES, UN DERECHO AMPUTADO
Authors:   UNIVERSIDAD CATOLICA DE SANTA MARIA, AREQUIPA-PERU, MANRIQUE SALINAS JOSE ANTONIO
Published: November 2022

The recall is a fundamental right and at the same time a mechanism for citizen participation that allows determining whether to remove an elected authority (regional or municipal) from his post before the expiration of the mandate. In 2014, for political reasons, Law 30315 was passed, which modifies the revocation of elected authorities at the regional and municipal levels. Although it was argued that it was to improve this participatory mechanism, the real cause was to help a controversial mayoral authority that still went through that consultation. However, from that moment it was possible to dissuade and truncate future recall processes in the country. Although it was thought that this reform would improve management, governance and institutionality, it is observed that this has not been the case. The cases of corruption, incapacity and opacity in local management have not receded, on the contrary they have increased. The most significant is for human rights. The accessibility and effectiveness of this fundamental right for the citizen have been seriously affected. Keywords: Recall, right, mechanism, partipatory, accountability

RESÚMEN: El presente trabajo pretende explicar las ventajas de transmisión de energía eléctrica en corriente continua, frente a la transmisión de energía eléctrica en sistemas de corriente alterna, como fuente energética en el uso sustentable para las viviendas y comercial. El uso alternativo de transmisión de energía en CD es una tendencia cada vez más predominante, especialmente para reducir las pérdidas que se presentan en sistemas en alterna y la mayor potencia de transmisión. Estos sistemas permiten reducir la tensión, en comparación con los sistemas trifásicos, como puede deducirse del peso relativo de conductor para una tensión máxima dada. Los métodos para conseguir grandes potencias a tensiones elevadas en corriente continua no han progresado al mismo ritmo que los adelantos en corriente alterna, y hoy día, casi no existen sistemas comerciales de alta tensión en corriente continua. El desarrollo de las aplicaciones industriales de la electricidad que iniciaron a fines del siglo XIX, se orientó sobre dos caminos, la corriente continua y la corriente alterna, esta última en distintas frecuencias que se fueron unificando en las hoy difundidas 50 y 60 Hz. Si se analiza cual es la mejor frecuencia para la transmisión de energía eléctrica a gran distancia, se observa que 50 Hz es mejor que 60 Hz, y si intenta optimizar se llega a la conclusión que a menor frecuencia, mejor transmisión.

How to Compose a Landscape: Reflections on Procedure in César Aira’s An Episode in the Life of a Landscape Painter
Authors: McConnell Anne
Published: November 2022

In César Aira’s short novel, An Episode in the Life of a Landscape Painter, the narrator describes the work and travels of German landscape painter, Johann Moritz Rugendas, in the Argentinian countryside. Rugendas, a landscape painter inspired by the work of naturalist, Alexander von Humboldt, commits himself to a strict procedure that attempts to document not only the variety of organisms in a given landscape, but also their relationship to one another. Rugendas and his fellow painter, Robert Krause, practice the Humboldtian procedure while reflecting upon and discussing matters related to artistic representation and composition. Those conversations also reflect the perspective of a contemporary Argentinian novelist, who also happens to obsess over the procedures and tools that define the work of art, and writing. While the novel begins as a biographical account of a specific trip Rugendas took to South America, it changes course near the middle when the painter is struck by lightning, twice, and is subsequently violently dragged across the pampas by his frightened horse. At this turning point, Aira’s novel, and Rugendas’s life, becomes increasing surreal, yet the painter never turns his back on the procedure. An Episode on the Life of a Landscape remains a meditation on artistic mediation, drawing attention to the eye and hand of the artist in the act of composition.
On the Nature of the Border: Trash Thresholds in Luis Alberto Urrea’s By the Lake of Sleeping Children
Authors: McKay Micah
Published: November 2022

In this essay, I undertake an analysis of Luis Alberto Urrea’s non-fiction book By the Lake of Sleeping Children (1996), which portrays a community of trash pickers and orphans in Tijuana at a moment in which the effects of NAFTA and an increasingly militarized approach to policing the U.S.-Mexico border were taking shape. My engagement with the text combines close reading with concepts from both ecocriticism and biopolitics in order to tease out the way in which Urrea’s vignettes trouble received notions of progress, freedom, and containment. By considering the book’s deployment of two descriptive techniques for rendering the garbage dump and other spaces—one, a technique I call “time-lapse description” and the other, the insistent use of lists—I propose that the border zone that Urrea depicts is a space from which to think through the troubling and mutually-imbricated environmental, political, and economic crises that are paradoxically exceptional and exemplary of the current order of things.
Borders and Butterflies in José Manuel Prieto’s Livadia/Nocturnal Butterflies of the Russian Empire
Authors: Kressner Ilka
Published: November 2022

In Cuban novelist José Manuel Prieto’s ‘Russian Trilogy’, and in particular, in the novel Livadia/Nocturnal Butterflies of the Russian Empire (1997), the experience of crossing borders and the reflection on how to pass safely, and often secretly, is vital. The geographical borders that take center stage are those of the former Soviet Union of the 1990s and adjacent Northern and Eastern countries as well as the Black Sea. In a first step, this essay examines the portrayals of changing borders, changing concepts of the border as well as the protagonist’s main strategies of border-crossing in the novel. In a second step, it explores the impact of a seemingly lighthearted metaphor, that of the butterfly and in particular its wings, to elucidate what I see as Prieto’s protagonist’s innovative approach of reacting to the experience of the border and his previous hyper-individualist attitudes when facing it. This experience is intrinsically linked to the role of writing and reading. Both hold a transcending potential for the narrator, as it is through acts of reading and reiterated attempts at writing that he begins to engage in a process of care for himself and others and devise transformative forms of being with others, even virtually, when a spatial or temporal separation prevents real encounters. His pondering on his previous restless crisscrossing of national confines may thus help, in the most fortunate moments, transcend spatial and conceptual confines and broaden what he calls the notion of an “imaginación aduanal.”
Art as Advocacy: Protecting the U.S.-Mexico Border Environment in Amanda Keller Konya's "Specimens"
Authors: Whittingham Georgina
Published: November 2022

Amanda Keller-Konya's multilayered photographic image construction in "Specimens" from North America's Most Polluted River" helps the viewer perceive the magnitude of the damage sustained by US-Mexico's border area residents in California's Imperial Valley and the effort necessary to clean the area's New River. The river originates in Mexicali city, capital of Baja California, northwestern Mexico, crosses the border, flows north through California's Imperial Valley, and empties into the Salton Sea, the state's largest and most contaminated lake. A sustainable environment is crucial to the health of the valley's residents and farms that supply most of the nation's winter produce. Recovery of the area's ecosystem requires solving the impact of agricultural runoff and toxic dust as less water flows into the Salton Sea, a body of water vital for the wellbeing of Southern Californians, the fish, and the migratory birds that depend on it for survival.
Refoulement as Biopolitical Praxis: Subalternity, Ethnography, and Ethics at the Mexico-Guatemala Border
Authors: Kennedy John
Published: November 2022

This article analyzes the Mexico-Guatemala border through the lens of the author's sensory ethnographic engagement there. It also uses oral history interviews and collaboration undertaken with refugees, migrants, and deportees. It argues for the contravention of human rights and refugee rights under the Trump Administration as an aspect of a longer history of biopolitics enacted in border regions and beyond them. It draws on border studies and notions of immunity in biopolitics to develop this argument, and its uses collaborative visual ethnographic practices as a way to consider the border.
Centering Climate Disaster: A Labor Immigration Driving Force
Authors: González Lyrianne
Published: November 2022

Labor migration is predominately studied through anthropocentric modes of analysis. This review essay explores, demonstrates, and argues that the environment and climate disaster can be driving forces of labor migration. While the scholarship explored as part of this essay, including text, a documentary, and photographs, demonstrate how non-human assemblages, climate and the environment, impact labor and subsequently the family unit and migration, they also call attention to the Anthropocene, the current moment that we occupy as humans as the dominant influence on climate and the environment. Given the impact of climate disaster on labor migration, it is important to decenter past anthropocentric modes of analysis focused on socioeconomic disparities.

EA-NET: A Hybrid and Ensemble Multi-Level Approach For Robust Anomaly Detection
Authors: Soni Jayesh , Prabakar Nagarajan , Upadhyay Himanshu
Published: November 2022

In the current world, the applications of anomaly detection range from fraud detection to diagnosis in the medical area. Most of the current methodologies are applicable only when a particular dataset pertains to certain assumptions and a distinct domain. Such assumptions require prior knowledge of the dataset. The training development cycle time to find the best single model is time-consuming and challenging. Unsupervised anomaly detection methods do not use the target label for training. However, they result in high false positive rates. In this paper, we address the problem of the ensemble anomaly detection approach that generalizes well across multiple domains. We design a multi- level hybrid approach. At the first level, we train several weak classifiers (weak one class classifiers). Next, we utilize deep learning-based AutoEncoder to reduce the dimension of the dataset. These are the two sets of hybrid features. Next, different one-class classifiers have their strength and limitations. Thus, we propose an adaptive weightage approach that gives the weight to each classifier. Next, this input is passed to the second level. At this level, we have a deep neural network that learns the patterns of the dataset and generates an adaptive dynamic threshold to discriminate the input feature as an anomaly or benign. The major benefit of this approach is the low false-positive rate. The training time is reduced due to the reduction of the input feature dimensions at the first level.
Mutation Event and Fuzzy Active Rule Processing in a Graph Database System
Authors: Jin Ying , Shah Vaidehi
Published: November 2022

A graph database system is a type of NoSQL databases that is based on the graph data model using nodes and arcs. Existing graph databases are passive and can only handle crisp data. Information in the real world can be imprecise and vague rather than crisp. Integrating fuzzy logic into database systems allows users to use uncertain data, which presents the degree to which something is true. Compared with passive databases, active databases support event handling by monitoring and reacting to specific circumstances automatically. This paper describes our approach of incorporating fuzzy concepts and active rules into a graph database system. Our recent publication has described our work of temporal event processing. This paper focuses on mutation events handling and active rule processing in a fuzzy system, covering the language model, the execution model, and architecture design. The language model defines the rule structure and contains the metadata for rule processing. Architecture design identifies the system's architectural components and user interfaces including rule specification interface and query interface. The execution model handles rule processing and execution at run time. A supply chain application is used to demonstrate the examples of active rule specification and execution.
COMPLEX FORMATION OF IRON IONS WITH FUNGAL MELANINS
Authors: Bagirov R. , Bobrova E. , Gafarova H. , Bagirova O.
Published: November 2022

The paper presents and discusses the results of experimental studies of the complex formation of iron ions with melanins isolated from forest beech chaga (faqus sylvatica) and birch chaga (betula), which exhibit high antioxidant activity. Melanins were isolated by alkaline extraction and precipitation in an acidic medium. To identify the isolated pigments, their IR and EPR spectra were recorded. The complex formation of iron ions with these melanins was studied by the method of gamma-resonance spectroscopy (GRS). It has been established that fungal melanins are able to effectively bind iron ions both in their two- and three-valence states. It is significant that fungal melanins, like melanins of animal and plant origin, are able to directly bind prooxidant Fe2+ ions and oxidize them to prooxidant inactive Fe3+ with subsequent complexation. The activity of these processes increases as the pH of the reaction medium increases and the suspension is illuminated with visible light.
DINITROSYL IRON COMPLEXES AS LIPID PEROXIDATION INHIBITORS
Authors: Grachev D. , Medvedeva V. , Shumaev K. , Lankin Vadim , Ruuge E.
Published: November 2022

The paper considers the effect of dinitrosyl iron complexes (DNIC) on the processes of free radical lipid peroxidation, which make a significant contribution to the development of many pathological conditions. These processes damage lipids and other macromolecules, and, in addition, the end products of lipid peroxidation are mutagens and carcinogens. The search for new antioxidant compounds capable of inhibiting lipid peroxidation has a fairly long history, but there are still many questions, including those related to potential clinical applications. In the framework of this work, data were obtained that allow expanding and supplementing the idea of DNIC as significant antioxidant agents. With the use of EPR spectroscopy and spectrophotometry, it was shown that dinitrosyl iron complexes are able to inhibit lipid peroxidation in model systems with tert-butyl hydroperoxide and cytochrome C, as well as in experiments with low-density lipoproteins during their oxidation with copper ions. Presumably, DNIC can be used as a therapeutic agent that prevents or reduces lipid damage and the accumulation of toxic end products of lipid peroxidation.

Published: November 2022

Visual perception plays a crucial role in providing the brain with the information it needs to make decisions, build a picture of the world, and adapt to changing environmental conditions. Under conditions of "dry" immersion, which simulates the effects of weightlessness on the human body, contrast sensitivity and tremor eye movements were studied under changing environmental conditions. The study involved 10 volunteers (mean age 30.8±4.6 years). The contrast sensitivity of the visual system was recorded using the method of visocontrastometry. We presented the Gabor elements with a spatial frequency: 0.4; 0.8; 1.0; 3.0; 6.0 and 10.0 cycle/deg. The parameters of eye micromovements, i.e., the amplitude and frequency of eye tremor oscillations, were recorded using an optical system providing high-frequency video recording. The measurements were carried out the day before immersion in the immersion bath, on days 1, 3, 5, and 7 of “dry” immersion, as well as the next day after its completion. A change in contrast sensitivity in the range of low and high spatial frequencies, as well as in the amplitude of eye micromovements, was established. The data obtained today are a new step in the search for methods for an objective assessment of the functional state under changing environmental conditions.
EXPRESS ESTIMATION OF PLANKTON SIZE FRACTIONS IN THE WATER AREA OF SEVASTOPOL IN WINTER 2021-2022: MODEL STUDIES
Authors: Ufimceva M. , Kuznetsov A.
Published: November 2022

For the purpose of monitoring the water area of Sevastopol a line of devices for plankton macrofiltration in the size range from 2 mm to 2 microns has been developed. Twelve stations have been chosen from Inkerman to Fiolent with total length of 30 km. From piers far out at sea, 50-500 liters of seawater were sampled from the surface and filtered through a system of successive sieves 2 mm, 300, 150, 84 microns and a 2 μm fiber filter. In the winter of 2021-2022, when the seawater temperature was 8 °C, the diversity of plankton morphotypes was low. For all stations, the number of morphotypes increased as the size fraction decreased in the form of ecological pyramids. It was found that the richness of morphotypes in Inkerman is significantly lower than at other stations. Samples from neighboring stations may differ in the composition of morphotypes up to 50% (spatial section). Also, sea water samples taken at the same station with an interval of 1.5 months differed by 50% in the composition of morphotypes (time slice). The obtained results indicate that the developed technique of sequential filtration gives a visual representation of the state of meso-, micro- and nano-plankton in seawater samples.

Published: November 2022

In the 1st millennium BCE Sri Lanka was central to the wide-spanning trading networks in the Western Indian Ocean region. Population agglomerations grew on the coast and further inland, where Anuradhapura emerged as the major central place. Parallel agglomerations formed in the south in Tissamaharama and in the north on Jaffna Peninsula in Kantharodai. The site of Kantharodai on the northern tip of Sri Lanka is the largest known early historic mound site on the Jaffna Peninsula, thought to represent the ancient centre of the region. The Early Historic occupation of Kantharodai began ca. 400-100 BCE. In our study we focus on the older historic occupation phase at Kantharodai, represented by a rich midden deposit of domestic refuse that offer insights into the environmental conditions faced by early occupants of the site and their modes of subsistence. We provide a glimpse into the subsistence strategies of the earliest settled population in Kantharodai who augmented a diet based on domesticated livestock through multiple wild species from forests, swamps, mangroves and marine habitats. Based on the faunal evidence from early Kantharodai, this complex socio-economic structure appears to have been in operation, confirming proposed models of mixed economies in operation in the Early Historic period of the region.

O presente artigo aborda a política pública de educação ambiental para capacitação de gestores ambientais municipais, desenvolvida pela Superintendência do Ibama, em Pernambuco, com o objetivo central de estimular e qualificar a atuação dos municípios na implantação e gestão da agenda ambiental pública, no âmbito de suas competências, visando ao fortalecimento do Sistema Nacional de Meio Ambiente -Sisnama. O planejamento das etapas desta política pública e a escolha das microrregiões e dos municípios, contemplados em cada atividade educativa proposta, foram executados com base em dados prévios e em informações levantadas em diagnósticos socioambientais realizados durante visitas
da equipe técnica do Ibama/PE às localidades selecionadas. As ações educativas ocorreram por meio da promoção de oficinas participativas, voltadas aos gestores ambientais públicos desses municípios. Os temas e as metodologias adotadas nessas ações foram definidos pela equipe técnica do Ibama/PE, em parceria com outros órgãos ambientais, integrantes do Sisnama, convidados a participar das atividades
propostas. Entretanto, no decorrer da implementação desta política pública, verificou-se o surgimento de diversos desafios para a continuidade das atividades e para a mensuração dos resultados almejados, dentre outras questões que serão discutidas e aprofundadas ao longo deste artigo.

Comparative study of once daily tacrolimus (extended-release capsule) versus conventional twice daily tacrolimus in renal transplant recipients
Authors: Sanjay Srinivasa
Published: November 2022

Background: One of the common causes of chronic allograft nephropathy is nonadherence to medications, contributing to 30% of graft loss in the developed world. The non-adherence is attributed predominantly to pill burden. Once-daily dosing of tacrolimus instead of conventional twice-daily dosing may enhance adherence to medication and improve long-term outcomes. The present study is a retrospective analysis comparing the safety and effectiveness of De Novo (use from day 1) once daily (OD) Tacrolimus (extended-release capsules) to conventional twice-a-day (BD) tacrolimus, in renal transplant recipients operated at Suguna Hospital Bangalore India. Material and Methods: Records of 24 Transplant patients on De novo OD Tacrolimus were analyzed and compared retrospectively to 24 transplant patients treated De Novo with conventional BD tacrolimus on a regular follow-up for at least 2 yrs. post-transplant at our center. Results: Various parameters recorded till the last follow-up were analyzed and compared. The average weight of the cohort (64.6 kg vs. 66.6 kg), average tacrolimus dose (2.7 mg vs. 2.15 mg), average Tac dose/kg body weight (0.04 mg vs. 0.03 mg), average Sr.Creatinine, at Last, Follow up (1.2 mg/dl vs. 1.32 mg/dl) were comparable in both groups and were statistically insignificant (p > 0.05). However, there was a higher incidence of Post-Transplant Diabetes Mellitus (PTDM) noted in the Conventional BD Tacrolimus group (20.83%) compared to the OD Tacrolimus group (4.1%) and it was statistically significant (p = 0.17). The Infection rate of 41.67% in the conventional BD Tacrolimus group was much higher compared to the OD Tacrolimus group (4.17%) which was statistically significant (p = 0.01). There was 100% patient and graft survival at the end of two years in both groups. Tacrolimus Dose for OD and Conventional BD dosing were similar, unlike earlier studies recommending a 10% increase in dose for OD tacrolimus compared to BD dosing. Conclusion: OD Tacrolimus dose is comparable to conventional BD dose Tacrolimus in its safety and Efficacy; however, it scores over conventional BD dose Tacrolimus in terms of post-transplant infections and post-transplant diabetes mellitus (PTDM) and a more stable serum trough level.

Myofascial pain syndrome caused by damage to the paravertebral muscles is considered as one of the causes of chronic back pain. At the same time, there is not enough information about the condition of the paravertebral muscles, and it is contradictory.

The aim of the work is to elucidate the presence and severity of structural and functional changes in the paravertebral muscles and their role in the development of chronic nonspecific pain in the lower back in women.

Material and methods. Morphological, immunohistochemical examination of a muscle tissue biopsy was performed in 17 patients aged 24 to 59 years (average age — 41.5 ± 12.1 years) with CNS (average duration of pain syndrome 10.0 ± 6.9 months) caused by myofascial pain syndrome, as well as determination by gel electrophoresis of the isoform composition of giant sarcomeric proteins titin and nebulin.

Results. Morphological examination revealed no signs of necrosis, proliferation of connective and adipose tissue, inflammatory infiltration. The transformation of the myosin phenotype in the direction of an increase in the proportion of “fast” type II muscle fibers was revealed in the biopsies of the patients’ muscles. A decrease in the content of giant titin and nebulin proteins associated with myosin and actin in the sarcomere was also found.

Conclusion. The data obtained indicate a violation of the contractile function of the paravertebral muscle in CNS.

A 20-year-old patient was presented with subacute onset of headache, nausea and vomiting. Testing of nasal/oropharyngeal swabs indicated the presence of SARS-CoV-2 RNA, and later the antibodies to this virus were found. The treatment in the hospital for Coronavirus 19 Disease (COVID-19) provided only temporary relief, and the patient then was referred to the Regional Stroke Center (RSC) to exclude a subarachnoid hemorrhage. RSC neurologists drew attention to multiple skin nevi in the patient. Brain MRI demonstrated abnormal T1 hyperintensity in the brain leptomeninges, with leptomeningeal contrast enhancement as well as hyperintensity in amygdala regions on T1 weighted images, bilaterally. The anomaly of the Dandy-Walker malformation complex was also revealed. Cerebrospinal fluid (CSF) analysis showed elevated protein (0.52 g/L), low lymphocytosis (lymphocytes, 6 in mm3), and decreased glucose (1.8 mmol/L). Neurocutaneous melanocytosis (NCM) was diagnosed, which neurological manifestation was probably triggered by COVID-19. The patient’s vision gradually progressively worsened. In 2.5 months after the clinical manifestation of NCM, fundoscopy revealed optic discs atrophy (despite the absence of previous edema), and repeated CSF analysis showed atypical cells with characteristics corresponding to melanoma. Malignant transformation of cerebral melanocytosis was suspected, and the patient was referred to an oncological dispensary for further therapy. In the presented literature review, special attention is paid to the issues of neuroimaging, cytological and immunocytochemical diagnostics of NCM.

Motor chronic inflammatory demyelinating polyneuropathy (M-CIDP) is a form of atypical CIDP. This article presents a clinical observation of M-CIDP in a 15-year-old boy, as well as a description of laboratory and instrumental diagnostic data. The boy had a chronic development (> 2 months) of flaccid tetraparesis, predominantly of the proximal muscles of the limbs, without sensory disorders. According to electroneuromyography, there were signs of demyelinating lesions of the proximal parts of the peripheral nerves. There was an increase in the thickness of the nerves of the upper limbs according to ultrasound. In the liquor protein-cell dissociation, as well as in the blood, IgG antibodies to the surface glycoprotein S of the SARS-CoV-2 coronavirus were found. The clinical and neurophysiological picture corresponded to the reliable criteria for CIDP. The therapy with intravenous immunoglobulins had a significant positive effect in the form of an increase in the strength of the limb muscles.
