Prospects for the development of regulatory and legal support for the policy of the Union State of Republic of Belarus and Russian Federation in the scientific, innovative and educational spheres
Authors: Klimuk Vladimir V. , Zelepukin Roman V.
Published: April 2023

The regulatory and legal environment in the field of scientific, innovative and educational cooperation between Belarus and Russia within the framework of the Union State is studied. The review of normative legal acts regulating the issues of integration of Belarus and Russia in the vector of scientific-technical, educational cooperation is presented. Prospects for the development of regulatory support for the policy of the Union State in the scientific, innovative and educational spheres are highlighted. The subject of this study is the regulations of the Union State and its member countries that regulate and establish the vectors for the development of a set of measures in the scientific, innovative and educational spheres within the considered interstate association, the practice of applying and implementing these acts, as well as doctrinal views and approaches in relation to the stated topic. The purpose of the study is to identify the degree of institutionalization of the policy of the Union State in the scientific, innovative and educational spheres as a set of targeted measures for the development and implementation of established goals and objectives in given areas of social relations and socio-economic status, as well as to establish the level of regulatory and legal support for this set of measures. We come to the conclusion that at present, the regulatory and legal support of the activities of the Union State in the scientific, innovative and educational spheres is of a provisional nature, but does not have a systemic expression, which is especially manifested in the insufficient degree of institutionalization of the policy of the Union State in the areas under consideration. Law-making, law-application and law-enforcement forms of normative-legal support of policy in the considered spheres are singled out and characterized.
Legal and other related aspects on the issue of providing medical care to cancer patients in conditions of risks of spreading and countering coronavirus infection (COVID-19) and its strains: “at the junction” of professional views and experience
Authors: Orckhanova Tat’yana M. , Dem’yanov Vladimir N.
Published: April 2023

A lively interest in the topic of the real state of affairs in the field of healthcare, regarding the determination of the level of cancer incidence in Russia, the search and development of fundamental and progressive approaches to the tactics of treating cancer patients, the quality of palliative care, and even during a situation associated with a high level incidence of COVID-19 and acute respiratory viral infections, can hardly be questioned in terms of substantiating its relevance. The subject of the study is the modern system of providing medical care to cancer patients, from the point of view of legal regulation and medical practice, existing and predicted “pros” and “cons”. Tasks: to prove the relevance of the problem in the quantitative and statistical aspect, to reveal common and special characteristic elements (“traits”), to identify risks, legal bases and their assessment, the most successful legal solutions in the appropriate direction, as well as to draw practice-oriented conclusions, and, first of all, related to the adoption of a new departmental order for the provision of medical care in Russia in the field of “oncology” from January 2022. In a methodological way, the empirical method of analysis, the method of synthesizing “legal matters” that define and provide a system of care for cancer patients in modern conditions of countering coronavirus infection, is quite actively used. The results obtained will be interesting for studying and taking into account in the environments of medical and legal communities interested in similar or related topics in rethinking, contrasting, developing scientific and medical legal, special, expert and other views and hypotheses.
The work of the Soviet advocacy to provide free legal assistance to Russian citizens and promotion of legal knowledge in 1918–1940 (on the materials of the Kursk region)
Authors: Pashin Vasilii P.
Published: April 2023

At present, not only theoretical, but also pragmatic interest in the historical experience of the Soviet state is growing. Not infrequently, this experience is passed off as short stories in modern reality. One of these misconceptions is the provision of free legal assistance to Russian citizens. The purpose of this work is to analyze the process of formation and activities of the lawyer community in Soviet Russia, where the main task is to study the identification of the reasons for the provision of free legal assistance to the population. The conclusion about the regulatory function of the state in providing comprehensive legal assistance to the population is substantiated. The methodological approach is based on the historical method, the formal legal method, and the dialectical method. It is established that the Soviet state administratively determined the rates for legal services provided, depending on the social status of a citizen and his income. The processes of growth of categories of persons receiving legal assistance free of charge are revealed. The role of the advocacy in the promotion of Soviet normative legal acts, primarily in the peasant environment, its public work as a whole is shown. Reasons and methods of liquidation of private practicing lawyers are substantiated. The identified documents allow you to re-evaluate a number of aspects in the activities of the Bar in the specified chronological framework.

Authors: Siluyanova Natalia M.
Published: April 2023

The formulation of the problem is due to the priority of the state’s tasks in the field of fire safety and the need in this regard for the development of legal regulation of fire insurance, which in turn focuses on the development of regulatory legal acts regulating public relations in the field of fire insurance. Law-making activity is inextricably linked with the application of legal and technical rules, with the development of precise terms. There are some problems of terminological uncertainty in the legal regulation of fire insurance. The purpose of work is to analyze the legal and technical characteristics of the term “fire insurance” used in legal acts, to determine the degree of its compliance with the requirements of terminological accuracy. The research is aimed at solving problems related to terminological uncertainty in the legal regulation of fire insurance. The subject of the study includes regulatory legal acts, court decisions, insurance rules, scientific texts using terms related to fire insurance in their content. The methodological basis is made up of general scientific methods. The method of dialectics, system-structural, formal-legal, comparative and other methods are used. The general theoretical views on concepts, terms, definitions are investigated. The lexical properties of the accuracy of the term “fire insurance” are considered. The discrepancy between the semantic content of the term “fire insurance” and its purpose has been revealed. The use of the term “fire insurance” is proposed and an attempt is made to define the concept corresponding to this term by the author. The conclusion is made about the possibility of using the term “fire insurance” in legal texts.
Some aspects of the legal regulation of surrogacy
Authors: Kravchenko Natalia V. , Trufanova Alexandra Y.
Published: April 2023

The relevance of the topic is due to the fact that, for various reasons, citizens have become more likely to turn to such a method of assisted reproductive technologies as surrogacy. At the same time, today this institution has many contradictions in terms of legal regulation. In December 2022, amendments were made to Federal Law No. 538-FZ “On Amendments to Certain Legislative Acts of the Russian Federation” (Collection of Legislation of the Russian Federation, 2022, no. 52, section 9368), the practical implementation of which is designed to eliminate existing problems, however, a number of legal, moral and ethic issues arising from the surrogacy procedure remain unresolved. With this in mind, the purpose of the study is to conduct a legal analysis of surrogacy technology and identify ways to resolve existing contradictions. The methodology consists of dialectical, structural, formal-legal and comparative-legal methods, analysis and synthesis. Within the framework of the study, the legal nature of the surrogacy contract, its content, subject composition were analyzed, the problematic legal aspects of the practical application of surrogacy technology were investigated, including the relationship between the achievement of the purpose of the contract and the consent of the surrogate mother to register genetic parents as such. It is noted that the issues of the implementation of the surrogate mother’s rights to abortion and the possibility of embryonic screening for the presence of genetic diseases before the embryo transplant remain unresolved. The solution to all issues is seen in the development and adoption of a systemic regulatory act regulating the use of surrogacy procedures.

¿Adiós al estado laico?
Authors: Garrard Virginia
Published: April 2023

Desde la segunda mitad del siglo XX se ha producido un aumento bien documentado del número de personas que se identifican como protestantes evangélicos. La Iglesia Católica, marginada durante mucho tiempo por los ideales ilustrados del liberalismo, las políticas anticlericales y los hostiles proyectos de formación del Estado en toda la región, ha visto cómo se erosionaba su poder secular, político y social desde el siglo XIX, una tendencia en curso que ni siquiera un popular Papa argentino ha podido detener en el siglo XXI. La superestructura del Estado laico ha sido el leitmotiv político de las sociedades profundamente católicas de América Latina durante más de un siglo y, con algunas excepciones notables, la Iglesia católica ha desarrollado un modus vivendi relativamente cómodo con los gobiernos laicos de América Latina. Hoy, sin embargo, han surgido nuevos desafíos al Estado laico, no desde el catolicismo, sino desde potentes fuerzas políticas alineadas con sectores evangélicos y pentecostales.

Published: April 2023

The development of tourism potential is not only in nature tourism but culture tourism, the community protects cultural tourism in Lombok by carrying out the routine customs of Bau Nyale (re: Bau is catching, Nyale is sea worms). Traditional customs traditions are carried out as an effort to preserve culture in the form of entertainment and ritual processions. This is done as a dynamic in the recovery of the economic sector while developing the potential for cultural tourism in the Mandalika SEZ. This research is qualitative research with an exploratory approach, the phenomenon is analyzed with the theory of Symbolic Interactionism by George Herbert Mead, with a component of community social action in developing the potential of cultural tourism in Lombok. The result of the research is the Bau Nyale tradition with the adaptation of new habits carried out with wisdom to be an innovation in introducing the Sasak tradition to the wider community. Although in its implementation there is a reduction in activities, the potential of tradition is still manifested in a series of ceremonial events, so that it still exists as an attraction for the surrounding community and tourists, in addition, the historical site of the Princess Mandalika Statue is a priority area to visit. The involvement of human resources is important in the process of developing cultural tourism as an implementer of cultural socialization and promotion, implementers of cultural values and norms, with the synergy of local governments and traditional figures who contribute to the implementation.

Facing Newness and Smallness: A Multiple Case Study of Nonprofits Creating Schools
Authors: Henrekson Ebba , Andersson Fredrik
Published: April 2023

This paper utilizes the literature on liability of newness and smallness to examine new nonprofit school venture creation and explore what challenges new school ventures face. We ask the following research questions: What challenges and obstacles do new nonprofit school ventures face? How do new nonprofit school ventures manage to maneuver, mitigate, or overcome these challenges and obstacles? To answer these questions, we conducted a comparative case study of three nonprofit organizations operating schools in Sweden. Our material consisted of semi-structured interviews and archival documents. The article illuminates two salient challenges for new school ventures: the need for legitimacy from a diverse set of stakeholders and the marshalling of sufficient resources. To cope with these challenges, the organizations combined an outward conformist strategy with an inward resource replacement strategy. Moreover, even though all ventures experienced obstacles, the character and magnitude of these obstacles differed depending on their mode of emergence.

Text Encryption Analysis of Modified Symmetric Keys using Genetic Algorithm on Caesar Cipher and One Time Pad
Authors: Kurniasih Julia , Rezalti Dian Tiara
Published: April 2023

The problem of data security is essential because data must be maintained securely and in its integrity, starting with the sending procedure and ending with the intended recipient. One way to maintain data security is to use cryptographic techniques, which use data encryption characteristics to transmit messages in secret (information encoding). Information can be encrypted using the Caesar Cipher and One Time Pad, symmetric key cryptographic algorithms. The key must be changed as a critical component of the cryptographic procedure to enhance the data or text's security. This study aims to analyse text encryption on the Caesar Cipher and One Time Pad (OTP) algorithms using a modified symmetric key by implementing a Genetic Algorithm, an optimisation algorithm. The research phase begins by adjusting the key using two types of Genetic Algorithm crossover operators, one-point crossover and two-point crossover, applied to the Caesar Cipher and OTP algorithms. Then testing and analysis of the ciphertext strength are carried out by comparing the frequency of character repetition with the results of implementing the two modification keys to determine which encoding model provides a better data security strength.

Authors: Suhendar  , Solihat Rini
Published: April 2023

Ecology is a complex system, so it requires thinking skills to understand it. One of the skills that can be trained in ecological practicum lectures is systems thinking skills. Ecology practicum has the potential and strategic role in preparing quality students to face the era of industrialization and globalization. This potential will be realized if practicum activities can equip students with the ability to think logically, think creatively, think critically, and think systems, which ends up being able to solve integrated problems. To design an ecology practicum program that can train systems thinking skills, it is necessary to know the existing forms of ecological practicum implementation, students' systems thinking skills, and their logical thinking skills. This study aims to obtain information on the description of these three things so that it becomes the basis for developing a better practicum program. and adaptive to changes and developments of the times. This research is in the form of field research, namely research whose object is about the symptoms or events that occur in the subject group. 18 third-level students and 39 fourth-level students were selected as research subjects. Limited interviews were conducted with practicum assistants and course lecturers. The instrument used consisted of a logical thinking ability test, systems thinking scale, systems thinking test, and interview guidelines. The results of the study show practicum activities only practice the skills of collecting, processing, and analyzing ecological data. Students' logical thinking ability is in a “good” category, especially at the level of combinatorial reasoning. Students' systems thinking ability is low, especially forest thinking skills.

Authors: Ter-Zakarian Arthur A. , Joyce David M. , Lyons Steven , Bernasek Thomas L.
Published: April 2023

Case:

Two cases of revision total hip arthroplasty (THA) for pseudotumor and infection with persistent postoperative bleeding because of angiosarcoma are presented. After surgery, both patients' health deteriorated because of hypovolemic shock despite transfusion, pressors, embolization, and prothrombotics. Diagnosis was obscure and delayed despite extensive imaging. Standard and computed tomography angiogram were nondiagnostic and did not localize the tumors or bleeding. Repeat surgeries and biopsies requiring special staining ultimately revealed epithelioid angiosarcoma.

Conclusion:

A diagnosis of angiosarcoma was etiologic for persistent postoperative bleeding after revision THA and should be considered in such cases.
Study on evaluation method of failure pressure for corrosion cluster defects based on failure location
Authors: mingming sun , yanfei chen , wenhua wang , xin Li
Published: April 2023

The interaction between adjacent defects significantly influences the internal pressure bearing capacity of corroded pipelines. Therefore, the interaction between adjacent defects must be considered as evaluating the failurepressure of pipeline with corrosion cluster defects. The existing failure pressure evaluation methods of pipeline with corrosion cluster defects have the disadvantages of complex evaluation steps and poor applicability. In the paper, the failure mode of pipeline with corrosion cluster of two or more defects is studied by burst experiment of full-scale pipeline. The results show that for the corrosion clustercomposed of defects with obvious difference in internal pressure bearing capacity, the failure position is the defect with the minimum internal pressure bearing capacity; for the corrosion cluster composed of defects with no noticeable difference in internal pressure bearing capacity, the failure location is the defect in the center of the range of corrosion cluster. Based on the failure position of corrosion cluster, a "center failure location" method is proposed to evaluate the failure pressure of corrosion cluster defects. The method takes the defect in the failure position as the center, the influence of adjacent defects which interact with the central defect on its failure pressure is considered, and then the failure pressure of pipeline with corrosion cluster defects centered on the failure location is evaluated. Compared with the existing evaluation methods, the prediction error of this method is not reduced, but the evaluation conditions are less and the evaluation method is simple to operate and more applicable.

Published: April 2023

Non-native and invasive species are the second leading cause of species extinction and one of the major threats to freshwater ecosystems. Hemiculter leucisculus is one of the introduced species of Iran's aquatic ecosystems for many years (1967) that has been reported from Iran in the Anzali wetland for the first time. The aim of the current study is to assess the diversity and origin of H. leucisculus a non-native species and also its response to current and future climate change in Iran's freshwater. To this, we collected the specimen from the species distribution range in the country and performed the mitochondrial gene, cytochrome b (cytb) combining them with the 84 GenBank(NCBI) sequences. In addition, an ensemble model approach was used for future Species Distribution Modelings (SDMs) and it was estimated according to two Shared Socio-economic Pathways (SSPs): 126 and 585 of the MRI-ESM2 based on CMIP6. According to our results, all the samples examined in the current study originated from the same locatlity, the river basins of china. The results also show a high genetic and haplotype diversity that can have a positive effect on the success of its non-native in different catchments of inland waters of Iran. Afterward, the result of SDM maps, clearly illustrated that climate change would significantly affect the distribution of H. leucisculus and it showed a sharp tendency to expand over time in its distribution areas.

Published: April 2023

A twelve (12) weeks feeding trial on nine hundred and sixty (960) African giant land snails (Archachatina marginata ) fed various leaves was evaluated. The snails were allotted randomly on their experimental diets. The experimental diets were domestic wastes designated as the control (T1), Centrosema pubescence leaves (T2), Moringa oleifera leaves (T3), and sweet potato leaves as (T4). Each treatment had two hundred and forty snails and was replicated four times with sixty snails each per replicate. The proximate compositions of these leaves were analyzed and showed significant values on the moisture content, crude protein, ether extracts, crude fiber, ash, and Nitrogen free extracts respectively. Data were collected on the performance, carcass characteristics, nutrient digestibility, proximate composition and minerals contents of snail meat. The results on the final weight, weight gain, average weight gain and FCR of snails showed that T4 (121.46, 36.10, 0.52g and 1.49­­ ) were significantly (p <0.05) different across treatment groups. Results on carcass characteristics showed that T4 had superior live weight, dressed weight, foot and dressing percentage values compared to the other groups. Also, T4 revealed significantly (p<0.05) different across the diets on nutrient digestibility, proximate compositions of snail meat and the mineral composition of the snail meat compared to the other treatments. The study concluded that T4 (sweet potato leaves) significantly influences the performance, carcass characteristic and mineral compositions of the snail meat and should be recommended as snail diet for optimum performance at an affordable cost.
The Planetary Child Health and Enterics Observatory (Plan-EO): a Protocol for an Interdisciplinary Research Initiative and Web-Based Dashboard for Climate-Informed Mapping of Enteric Infectious Diseases and their Risk Factors and Interventions in Low- and Middle-Income Countries

Published: April 2023

Background: Diarrhea remains a leading cause of childhood illness throughout the world and is caused by various species of ecologically sensitive pathogens. The emerging Planetary Health movement emphasizes the interdependence of human health with natural systems, and much of its focus has been on infectious diseases and their interactions with environmental and human processes. Meanwhile, the era of big data has engendered a public appetite for interactive web-based dashboards for infectious diseases. However, enteric infectious diseases have been largely overlooked by these developments.
Methods: The Planetary Child Health and Enterics Observatory (Plan-EO) is a new initiative that builds on existing partnerships between epidemiologists, climatologists, bioinformaticians, and hydrologists as well as investigators in numerous low- and middle-income countries. Its objective is to provide the research and stakeholder community with an evidence base for the geographical targeting of enteropathogen-specific child health interventions such as novel vaccines. The initiative will produce, curate, and disseminate spatial data products relating to the distribution of enteric pathogens and their environmental and sociodemographic determinants.
Discussion: As climate change accelerates there is an urgent need for etiology-specific estimates of diarrheal disease burden at high spatiotemporal resolution. Plan-EO aims to address key challenges and knowledge gaps by making rigorously obtained, generalizable disease burden estimates freely available and accessible to the research and stakeholder communities. Pre-processed environmental and EO-derived spatial data products will be housed, continually updated, and made publicly available to the research and stakeholder communities both within the webpage itself and for download. These inputs can then be used to identify and target priority populations living in transmission hotspots and for decision-making, scenario-planning, and disease burden projection.

Authors: Lima Lucas , Ottoni-Boldrini Bianca M. P. , BOLDRINI RAFAEL
Published: April 2023

The Leptophlebiidae family of mayflies is diverse, with over 640 species and 140 genera worldwide. One of its subfamilies, Terpidinae, is restricted to the Neotropical region and consists of three genera, including Fittkaulus, which have four South American species. This paper describes the male imago of F. cururuensis, which was previously unknown, based on specimens collected in streams in the Caatinga and Amazon Forest regions of northern and northeastern Brazil. It can be differentiate by having the following combination of characteristics: upper portions of eyes on short stalk; forewing with reddish brown macula; abdominal terga I–VIII with posterior and lateral margins washed with black; penes with proximal half fused, distal half with a globose lateral lobe, and with a long, apically pointed and tubular medial lobe.

The oxidation of aromatics contributes significantly to the formation of atmospheric aerosol. Using toluene as an example, we demonstrate the existence of a novel molecular rearrangement channel in the oxidation mechanism. Based on both flow reactor experiments and quantum chemical calculations, we show that the bicyclic peroxy radicals (BPRs) formed in OH-initiated aromatic oxidation are much less stable than previously thought, and in the case of the toluene derived ipso-BPRs, lead to aerosol-forming low-volatility products with up to 9 oxygen atoms on sub-second timescales. Similar results are predicted for ipso-BPRs formed from many other aromatic compounds. This new reaction class is likely a key route for atmospheric aerosol formation, and including the molecular rearrangement of BPRs may be vital for accurate chemical modeling of the atmosphere.

Intelligent fault diagnosis is an important method in rotating machinery fault diagnosis and equipment health management. To deal with co-frequency vibration faults, a type of typical fault in rotating machinery, this paper proposes a fault diagnosis method based on the stacked autoencoder (SAE) and ensembled ResNet-SVM. Furthermore, the time- and frequency-domain features of several co-frequency vibration faults are summarized based on the mechanism analysis and calculated using actual vibration data. To realize and validate the high-precision diagnosis method of rotating equipment with co-frequency faults proposed in this study, the following three criteria are required: First, to improve the effectiveness and robustness of the ensembled model and the sliding window using data augmentation, adding noise, autoencoder (AE) and SAE methods are analyzed in terms of principle and practical effects. Second, ResNet is used as the feature extractor for the ensembled ResNet-SVM model. Feature extraction is carried out twice, and the extracted co-frequency fault features are more comprehensive. Finally, the data augmentation method and ensemble ResNet-SVM are combined for fault diagnosis and compared with other methods. The experimental results show that the accuracy of the proposed method can exceed 99.9%.

Hydrogen is drawing increasing attention as a carbon neutral energy carrier. The effects of climate change are increasing the pressure to establish hydrogen energy infrastructure. To facilitate the transition to hydrogen energy, a large number of hydrogen refueling station (HRS)s should be constructed throughout the entire transportation network. With a limited financial budget, constructing them simultaneously is not possible. However, it is economically to develop a systematic decision-making framework for determining construction priorities for HRSs. In this study, we proposed p-medianbased mixed integer linear programming (MILP) models to select location and construction priorities. The models aim to maximize the contribution impact that is represented by the sum of average distances between HRS and its allocated hydrogen vehicles. The metropolitan city of South Korea, Seoul is used as a case study to illustrate the applicability of the proposed methodology.

To prevent major disasters caused by mine engineering, the structure and early warning effect of microseismic monitoring systems in the mineral equipment manufacturing industry based on deep learning (DL) are explored under the background of artificial intelligence (AI). The purpose is to provide a reference for predicting the law of strata movement under high-intensity mining conditions. In this study, firstly, the principle of the microseismic monitoring sensor system is analyzed, and the structure of the microseismic monitoring system of intelligent mining face in the mineral equipment manufacturing industry is further understood. Secondly, as one of the AI technologies, DL introduces the Convolutional Neural Network (CNN) and transfer learning (TL) into the processing and intelligent warning of mine microseism signals. Moreover, an intelligent microseismic monitoring system based on CNN and TL for the mineral equipment manufacturing industry is constructed to realize the identification of microseismic events. Finally, taking the Xiaojihan coal mine as an example, the microseismic activity regularity of its mining face is analyzed, and the performance of various microseismic signal recognition models is compared. The results reveal that the TL-CNN algorithm in the model constructed in this study has the best performance. Compared with other methods, Mean Absolute Error, Root Mean Square Error, and Mean Absolute Percentage Error indicators have decreased by at least 28.2%, 21.0%, and 36.2%. This shows that the TL-CNN model-based multi-input sequence model is more suitable for forecasting rockburst risk. The mining microseismic signal processing model based on the CNN discussed here provides a reference basis for ensuring the accuracy of rockburst microseismic warning to some extent.

Background The COVID-19 pandemic has had a significant influence on the sleep health of healthcare workers (HCWs); however, there are no studies on this aspect in primary HCWs. The purpose of this cross-sectional, web-based study was to explore the prevalence and factors associated with sleep disorders among primary care providers during the first COVID-19 outbreak in 2022 in Shanghai.
Methods: From July 12 to August 15, 2022, primary HCWs were invited to participate in a survey of their sociodemographic and work-related characteristics, various sleep dimensions (regularity, quality, daytime sleepiness, timing, efficiency, and duration), and exposure to COVID-19 patients and a screening for common mental disorders (depression, burnout, and stress).
Results: A total of 313 primary HCWs participated the survey, representing 11 distinct healthcare roles. 84% of respondents showed a deterioration in at least one sleep dimension compared to those at pre-pandemic levels; sleep quality (decline of 66%) and daytime sleepiness (increase of 56%) were the most strongly affected domains. After excluding 145 primary HCWs with pre-pandemic “poor sleep,” positive depression screening (odds ratio [OR], 3.08; 95% confidence interval [CI], 1.59–5.98), weekly burnout symptoms (OR, 2.57; 95% CI, 1.32–5.03), and high psychological stress (OR, 4.51; 95% CI, 2.09–9.72) were associated with poor sleep patterns during the pandemic. After adjusting for significant differences between groups, for every 1-point increase in the perceived stress scale score, there was an associated 12% increased risk of poor sleep (adjusted OR, 1.12; 95% CI, 1.05–1.21; P=0.002).
Conclusion: A majority of the primary HCWs showed a significant worsening of sleep quality, with an increase in daytime sleepiness, during the first wave of the COVID‑19 pandemic in 2022 in Shanghai. HCWs with high stress were at a greater risk of sleep disorders.

Background/Objectives:To determine whether Descemet’s membrane (DM) scrolling occurs primarily along the vertical or horizontal axis and establish whether oval trephination along the axis of least scrolling can reduce the grade of the scroll.Subjects/Methods:The longest limbus-to-limbus axis on 28 sclero-corneal discs was taken as the horizontal axis. The horizontal (n=7) or (right angles to it) vertical (n=6) axis was marked on the DM before peeling it off. The direction and grade of scrolling was observed. Narrow strips (3-4mm wide) were then cut along the two axes (n=4 each) and the scrolling pattern observed. Ellipses (7x9mm) of DM were punched along the two axes (n=6 each) and the scrolls graded. Immunofluorescent staining for elastin, on horizontal and vertical tissue sections from 3 DM samples was performed. The intensity and thickness of elastin staining were measured.Results:24 (85.72%) DM samples showed scrolling along the horizontal axis, none along the vertical axis, and 4 (14.28%) showed a spiral scroll, regardless of which axis was marked (grade 3.7 and 3.6). Vertically oval discs showed significantly reduced scrolling (grade 1.2) compared to horizontally oval discs (grade 3.5). Narrow strips of DM showed a similar scrolling pattern. Immunohistology showed no difference in any of the parameters examined, along the two axes or from center to periphery.Conclusion:DM scrolls primarily along the horizontal axis. Vertically oval DM samples show minimal scrolling, which can be an advantage in DMEK. The differential scrolling is not determined by the distribution of elastin.
