Authors: Kovalevskaya M. A. , Antonyan V. B. , Sergeeva M. I. 
Published: July 2023

Purpose: to evaluate the impact of Optinol treatment on the ocular surface state in medical students with various types of ametropia.Material and methods. The study involved 3 groups of patients: two clinical groups and a control group. The first clinical group consisted of 34 students (68 eyes) with mild, moderate or high hyperopia, averagely aged 20.1 ± 0.5 years. The second clinical group consisted of 47 students (94 eyes) with mild, moderate or high myopia, average aged 20.6 ± 0.9 years. The control group was composed of 60 students (120 eyes), averagely aged 21.4 ± 1.2 years, with no ophthalmic pathologies. Each group received Optinol consecutively in three different formulations: Optinol® Gentle Repair: dexpanthenol 2 % and sodium hyaluronate 0.15 %, Optinol® Deep Hydration: sodium hyaluronate 0.4 %, Optinol® Express Moisturizer: sodium hyaluronate 0.21 %. The case histories of the patients and typical complaints were revealed by the questionnaire method. The state of the eyelids and the conjunctiva was assessed by biomicroscopy. To diagnose the dry eye syndrome (DES), special tests were used: LIPKOF, Schirmer and Norn tests.Results. Despite the higher LIPKOF scores in the 1st (hyperopic) group, showing stage III as compared to the 2nd (myopic) group where it scored stage I, the Norn test score showed a stronger reduction in the 2nd group. The LIPKOF test improved in the hyperopic group, falling to 1.23 ± 0.10 mm (stage I), which corresponded to one conjunctival fold. The index of tear film stability (Norn's test) increased in group 1 by 3.1 ± 0.1 sec, and in group 2 by 2.2 ± 0.2 sec.Conclusion. DES was found to be more frequent in hyperopic students. Optinol is a pathogenetically oriented drug, targeting tear production disorders and ocular surface changes. The drug demonstrates high efficacy, good tolerability and safety profile, so that it could be recommended for managing multiple types of ametropia.
Refraction changes in children with retinopathy of prematurity after transpupillary laser coagulation of the retina
Authors: Myagkov A. V. , Rozental P. V. 
Published: July 2023

The improvement in nursing routine of premature babies with low and extremely low body weight has increased their survival rate. Along with the growing number of such children, retinopathy of prematurity (ROP) occurs relatively less often and its outcome becomes more favorable. Modern approaches to the surgical treatment have led to a significant reduction in the incidence of blindness and visual disability caused by ROP. Yet, ROP remains one of the major issues in neonatal ophthalmology, often associated with refractive disorders.Purpose: to evaluate the refractive changes in children with ROP after transpupillary laser coagulation of the retina based by clinical experience.Materials and methods. We analyzed 5 clinical cases of children with ROP treated in Children's City Clinical Hospital No 1 during the period from 2013 to 2014. All patients underwent retinal transpupillary laser coagulation; its volume determined by the stage of ROP. Eye refraction data were noted at the age of 1 and 7 years. The quality of visual functions and the axial length of the eye were determined at the age of 7.Results. All patients had hyperopia of varying degrees at 1 years old. By the age of 7, one patient developed myopia, another one had emmetropia, while the rest of children had hyperopia of varying degrees. Regardless of the refractive error type, the axial length of the eye remained significantly below the age norm. The low quality of visual functions is due to the lack of full-time optical correction and irregular outpatient observation.Conclusions. Most often, hyperopia refraction in children with ROP is accompanied by a short axial length of the eye. Full-time optical correction should be prescribed, and spectacle wearing should be monitored by parents and ophthalmologists who observe the patients.

Published: July 2023

Purpose: to compare anatomical and optical parameters and aberrations of both eyes in patients with acquired and congenital anisometropic myopia.Material and methods. 22 patients (44 eyes) aged 18–35 (averagely, 25.2) with acquired and congenital anisometropic myopia were examined using the Galilei G6 optical eye system analyzer (Ziemer, Switzerland). The analysis of total, corneal and internal aberrations of the eye was carried out on an OPD-Scan III (Nidek) aberrometer.Results. In both groups with acquired and congenital anisometropic myopia, the axial length of the higher myopic eye was greater than that of the fellow eye. A greater asphericity and higher astigmatism of the cornea were revealed in higher myopic eyes of patients with congenital myopia as compared to acquired myopia. The total RMS HOA in congenital myopia was significantly greater in the higher myopic eye compared to the fellow eye (1.07 D and 0.68 D, respectively) and greater than in cases of acquired myopia. All HOA were greater in higher myopic eyes as compared to the fellow ones in cases of congenital myopia. In case of acquired myopia only the total coma appeared to be greater in the higher myopic eye. Corneal aberrations in acquired anisometropic myopia did not differ in the paired eyes. In case of congenital myopia, the total tilt was significantly greater in the higher myopic eye, and total coma and spherical aberration have lower values, even with a transition to negative ones (p < 0.05).Conclusion. The revealed differences of the wavefront of the eyes with anisometropic congenital and acquired myopia are rather a consequence of anatomical and optical differences (the axial length of the eyes and the topography of the cornea), than the cause of anisometropia.

Published: July 2023

Disorders of ocular perfusion are associated with huge amout of diseases, including such socially significant as diabetic retinopathy and glaucoma. To date, there is no gold standard for measuring ocular perfusion. An innovative method for two-dimensional assessment of eye blood flow — laser speckle flowgraphy (LSFG) — has been developed recent years and implemented in ophthalmological practice.Purpose: to evaluate the possibilities of LSFG for determining ocular blood flow and to find out the age dependence of the obtained indicators of ocular blood flow.Materials and methods. The study includes 60 healthy volunteers. The examined persons were divided into 3 groups of 20 people depending on their age — 20–40 years old, 41–60 years old, and over 61 years old. All examined persons had high visual acuity and normal blood pressure. The study was carried out on an LSFG-RetFlow device (Nidek). The shape of the pulse wave, its qualitative and quantitative characteristics including the main parameter of LSFG - MBR (Mean Blur Rate) were determined.Results. A significant decrease with age of most studied parameters of blood flow volume was revealed, the changes were significant (p £ 0.05). The highest MBR parameters were noted in the group of 20–40 years old. In the macular area, MBR values decreased more significantly in the group after 60 years age, while for the optic nerve head (ONH), a decrease has been already noted after 40 years age. In average, the decrease was 25–34 % for the ONH area and 33–38 % for the macular area. Changes of the other parameters of the pulse waveform had a similar trend.Conclusion. LSFG is a reliable method for quantifying ocular blood flow. Our data support that LSFG-derived MBR and pulse wave measurements may be useful biomarkers for ocular perfusion changes. The identified age-related blood flow changes should be taken into account during the analysis of patients data.

Published: July 2023

Purpose: to determine the role of the systemic angiotensin II (AT-II) in the pathogenesis of retinopathy of prematurity (ROP) and assess its prognostic value.Material and methods. 34 premature infants at risk of developing ROP were examined according to the ophthalmological ROP screening protocol adopted in the Russian Federation. Retrospectively, the infants were divided into 2 groups: those without ROP (n = 15) and those with developed ROP (n = 19). The average gestational age of those without ROP was 28.12 ± 0.64 weeks, their average body weight at birth was 1164 ± 118.6 g. The respective values for the group with ROP were 27.8 ± 0.6 weeks and 1142.6 ± 108.4 g. The two groups had similar extent of general somatic burden. At 32–35 weeks and 36–39 weeks of post-conceptual age (PCA), the infants of both groups were tested for the concentration of AT-II in blood serum using the enzyme-linked immunosorbent assay (ELISA).Results: on the 32–35 week of PCA, the average level of AT-II in blood serum of premature infants of the ROP group was significantly increased as compared to that of the non-ROP group (p = 0.03), while on the 36–39 week of PCA no statistically significant difference between the AT-II levels in the examined groups was found (p = 0.73).Conclusion. We established that the systemic AT-II level has a trigger role in the development of ROP. A high level of this parameter found at the onset of ROP can be considered as an early prognostic criterion for the risk of ROP development.

Authors: Pirogova E. S. , Fabrikantov O. L. , Nikolashin S. I. 
Published: July 2023

Purpose: to develop new approaches to Morgagnian cataract surgery by optimizing the phacoemulsification technique and reducing the risk of surgical complications.Material and methods. 22 patients (22 eyes) with hypermature Morgagnian cataract were divided into 2 groups. The main group I included 11 patients who underwent surgery according to the PEC technology using iridocapsular retractors, an intracapsular ring and the scaffold technique with the last nucleus fragment relocated into the anterior chamber. The comparison group II included 11 patients with PEC and IOL implantation using iridocapsular retractors and an intracapsular ring with no scaffold technique involved. In 7 patients of group I, the lens nucleus was considered “large” and in 4 patients, “small”. In 8 patients of group II, the lens nucleus was considered “large” and in 3 patients, “small”.Results. After 6 months, BCVA in group I was 0.60, whilst in group II it was 0.70. IOP in group I averaged 12.9 mm Hg, while in group II it averaged 17.90 mm Hg. The endothelial cell density (CD) in group I decreased by 241 cells and amounted to 2012.0 cells/mm2 , the endothelial cell loss was 10.70%, while in group II CD loss was greater. It dropped by 377 cells (15.60%) and amounted to 2039 cells/mm2 .Conclusions. The severity of involutional changes in the ligamentous apparatus of the lens in Morgagnian cataract was found to depend on the nucleus size. A working classification of Morganian cataract by the nucleus size has been proposed. The use of scaffold technique with the relocation of the last fragment into the anterior chamber made it possible to reduce the share of surgical complications to 18.18%. During phacoemulsification of Morgagnian cataract with small nuclei, surgical complications took place in both group I and II, which necessitates further improvement of the existing surgical technique of this type of pathology.

Authors: Erazo Ramirez Carlos , Sermet Yusuf , Demir Ibrahim 
Published: July 2023

Abstract

We introduce HydroLang Markup Language (HL-ML), a programming interface that uses a markup language to perform environmental analyses using the hydrological and environmental framework HydroLang. The software acts as a self-contained interface that uses HTML tags powered by the web component specification to generate simple hydrological computations that enable data analysis, visualization, and manipulation via semantically driven instructions. It enables hydrological researchers and professionals to use markup language to retrieve, analyze, visualize, and map data with basic programming skills. The components' adaptability enables users to run analytical routines that perform simple and complex analyses on the client side. We present the implementation details of the approach, the use of custom elements in web technologies and academia, and share sample usages to demonstrate the simplicity of use of the human-readable and computer-executable framework.

Abstract
This research studied the effect of boiler water released into rivers on various water properties, including density and viscosity. The equations of momentum, conservation, turbulence and energy were used with the relation between the temperature and water properties to describe those properties along the study reach. Simplifying of the partial equation was done to obtain the system of linear equation. Verification of a numerical model by conducting comparison of the observed data from Euphrates River at the Mussaib Thermal Power Station with those computed by the model. The comparison results of density and viscosity show an agreement with using statistical tests such as Chi square and RMSE. The results of the study showed that increasing the bed roughness from 0.04 m to 0.12 m causes a longitudinal retardation of the values of density and viscosity values about (26 and 22%) respectively and vertical advance of these values about (14 and 12% ) respectively. Increasing the water surface slope from (6 cm/km to 12 cm/km) causes a longitudinal advance of density and viscosity values about (19 and 12%) respectively and vertical retardation of these values about (16 and 13% ) respectively.

Abstract

Nine reservoir catchments (Chohal, Damsal, Dholbaha, Januari, Maili, Nara, Patiaria, Selaran and Thana) located in Shivalik foot-hills of Indian Punjab were prioritized using geospatial techniques and principal component analysis (PCA) for soil and water conservation planning. The selected catchments were demarcated using a digital elevation model (DEM) of 12.5 m resolution (ALOS PALSAR) in ArcGIS 10.4.1 software. The higher values of shape parameters (Ff &gt; 0.78, Re &gt; 0.8 and Cc ≥ 1) indicated circular shapes of Saleran and Nara dam catchments with high peaks for a shorter duration, from where the flood flows cannot be easily managed. These basins indicate coarse drainage density (Dd = 2.0–4.0 km km−2). The relative relief (Rrel) was also computed to the highest (0.124) for Saleran and Nara dam catchments, respectively. The geospatial techniques-based morphometric analysis helped to identify the shapes of the reservoir catchments including the factors affecting hydrological conditions and soil erodibility. The PCA application simplified the prioritization process via a reduction in the number of parameters. Thus, geospatial techniques-based morphometric analysis coupled with PCA-based prioritization is significant to identify the most critical reservoir catchment in a region for conservation planning. The study would be useful for implementing appropriate soil and water management measures in the highly prioritized reservoir catchment.

Abstract
Since the reform and opening up, China's economy has achieved amazing growth. At the same time of industrialization transformation, the traditional high-energy consumption and external growth model has brought serious environmental problems, and the pollution control situation is facing many difficulties. The Yellow River Valley gives birth to the Chinese civilization. With the formulation of the national strategy for ecological protection and high-quality development in the Yellow River Basin and the demand for green development, the control of industrial pollution has become the main task of environmental protection in the Yellow River Basin. However, the research on the ecotope pollution in the Yellow River Valley mainly stays in the theory and strategy. In response to the above problems, this paper would carry out scientific data analysis and high-dimensional research on the ecotope pollution in the Yellow River Valley from the perspective of green development and data analysis algorithms. The research results showed that the reconstruction probability of the Threshold-based Sparsity Adaptive Matching Pursuit (TSAMP) algorithm remained 100% when K was less than 50.
Indagação acerca dos sentidos do fenômeno educativo
Authors: Kuhn Martin , Arenhart Livio Osvaldo 
Published: July 2023

Diferentes perspectivas abordam a educação para além da racionalidade instrumental dominante. Uma delas é o diálogo entre a hermenêutica e a educação que produz termos alternativos para pensar o fenômeno educativo. Que sentidos queremos para o fenômeno educativo de nosso tempo? O objetivo aqui é refletir sobre as contribuições da hermenêutica para a educação. Parte-se do entendimento que a hermenêutica permite desvelar os muitos sentidos velados/entulhados presentes na educação. Aquilo que é instituído no âmbito da educação escolar e do trabalho educativo deve ser tomado como um fenômeno a ser reiteradamente questionado e refletido. Se hoje vivemos mergulhados na cultura do tédio, então, a hermenêutica pode ajudar a pensar na cultura do sentido para o fenômeno educativo, um contexto em que a definição de balizas mínimas voltadas à formação de autonomia cognoscitiva e moral parece bastante razoável. Este texto é um ensaio que entende que a matriz de racionalidade tem muito a contribuir à compreensão do fenômeno educativo de nosso tempo.

A Comprehensive Review on Inorganic Nanoparticles as Effective
Modulators of Amyloidogenesis
Authors: Chakraborty Debashmita , Mukherjee Aniket , Sarkar Nandini 
Published: July 2023

Abstract:
Many degenerative disorders have started to develop as a result of the deposition of insoluble
protein fibrillar clumps known as amyloid. This deposition mostly limits normal cellular
function and signaling. This build-up of amyloid in vivo results in a variety of illnesses in the body,
including type 2 diabetes, several neurodegenerative diseases (such as Alzheimer's disease and
spongiform encephalopathy), and Alzheimer's disease. Growing interest has been demonstrated in
nanoparticles as a potential treatments for amyloidosis throughout the past few decades. Inorganic
nanoparticles are one of them and have also been in substantial research as a potential anti-amyloid
drug. Inorganic nanoparticles have emerged as a good study candidates because of their nano size,
distinctive physical characteristics, and capacity to traverse the blood-brain barrier. In the current
review, we have focused on the effects of different types of inorganic nanoparticles on amyloidogenesis
and attempted to understand their underlying mechanism of action.

of Materials and under Various Contact Frequencies
Authors: Alaya Amine Ben , Kourda Férid , Mrad Charfeddine 
Published: July 2023

Background:
In order to harvest triboelectric energy for self-powered devices, triboelectric
nanogenerator technology (TENG) is used. It converts mechanical energy into electrical energy using
materials' contact motion.

Objective:
The purpose of this study is to produce electrical energy for different material pairs and under
various contact frequencies using triboelectric separation mode.

Methods:
To produce electricity through triboelectric separation mode, a vibratory exciter was used to
provide the contact frequency between the pairs of materials which were connected to an oscilloscope
by a capacitive electric circuit containing a diode bridge. The studied materials are: Mica, Polyamide
(Nylon), Polytetrafluoroethylene (PTFE), Polyvinylidene fluoride (PVDF), and Polyethylene terephthalate
(PET). Mica and Nylon are positive charge materials, while PTFE, PVDF, and PET are negative
charge materials. The material pairs are then: Nylon-PVC, Mica-PVC, Nylon-PET, Mica-PET, Nylon-
PTFE, and Mica-PTFE.

Results:
The increase of the contact frequency improves the recovered electrical energy for all the material
pairs. The produced electrical energy can reach 5μJ which allows supply for low consumption devices.

Conclusion:
The research results lead to identify favorable configurations of material pairs and contact
frequencies, allowing to recover enough electrical energy supply to low-power devices.
“Cuidado, presidente” – a não violência como compromisso ético
Authors: Wilson Victoria 
Published: July 2023

Tendo em vista o papel da polidez nas interações sociais, o presente estudo visa analisar uma carta na coluna do jornal O Globo, escrita por Fernando Henrique Cardoso (2021), ex-presidente do Brasil, ao então presidente Jair Messias Bolsonaro, considerando o conceito de face, de acordo com Goffman (1980), no âmbito da não violência, conforme Butler (2021). A carta é examinada como um projeto enunciativo, segundo a perspectiva bakhtiniana, a partir de uma abordagem qualitativo-interpretativista que permitiu que se buscassem indícios de estratégias linguístico-discursivas, de natureza polida, empregadas pelo signatário. Associados aos conceitos de face e ao de forças da não-violência, foram tomados como pressupostos os estudos de Elias (1939/1994) a respeito dos costumes e padrões civilizatórios que se ritualizaram ao longo da história do Ocidente, contrastando com um cenário marcado por movimentos e interações de impolidez e violência. Os resultados mostraram que a carta explicita princípios importantes, pilares fundamentais para a vida e sua continuidade: o princípio democrático, que preza a igualdade como forma de zelo pela vida de todos sem distinção, e a dignidade ou polidez, na reafirmação de uma prática verbal e social pautada na não violência.
