Authors: Duda Vadim V. , Nikonorova Ekaterina V. , Shibaeva Ekaterina A.
Published: April 2024

The purpose of the article is to reveal, in the genre of a personal interview, the opinion of the Director General of the Russian State Library, V.V. Duda, about the challenges that cultural heritage institutions face today, without which it is impossible to form the identity of the peoples of Russia. The peculiarity of the current moment lies not only in the need to perform its traditional function of collecting, preserving and making available the books and documents stored in the library, but also in modernization, taking into account the possibilities of digitalization, acceleration of traditional processes, diversity of services and increasing the level of comfort in serving users.

The use of the interview method has certain advantages in the context of social transformation, as it is essentially a method of qualitative analysis of the situation. Targeted questions focus on specific areas of the library’s activities in the development of artificial intelligence, digital bibliography, the importance of constant contact and discourse between humanities scholars and IT staff. What kind of specialists should work in a library today, what should be the system of library staff training, how and what can help libraries in new territories, how to be creative but remain on the foundation of traditional values and creativity — these and other questions were echoed in V.V. Duda’s answers.

It is important to emphasize the need to unite the efforts of the library community within the framework of the Russian Library Association, to increase its organizational role and project activity in solving the state task of developing the country’s intellectual capital.
The role of farming systems in the adoption of pest management practices: the case of the oriental fruit fly Bactrocera dorsalis in mango orchards in Senegal
Authors: Ndiaye Diatou , Brévault Thierry , Muriithi Beatrice W. , Zackariaou Boubacar , Belmin Raphaël
Published: April 2024

Description of the suject. In Africa, pest pressure has led researchers, policymakers, and international development stakeholders to develop and disseminate innovative pest management strategies. However, farmers reject some pest management strategies due to economic constraints, agronomic problems, or incompatibilities with their strategies, knowledge bases, and visions of desirable change. Objectives. In this paper, we study the pest management practices employed by mango producers from different farming systems against the fruit fly Bactrocera dorsalis, as well as the factors determining the level of engagement of these producers in managing this pest. Method. We surveyed 304 Senegalese mango growers affected by the invasive fruit fly Bactrocera dorsalis to understand which farming systems’ features could explain the adoption level of fruit fly management tools through multivariate data analysis. Results. Three types of farming systems characterized by a coherent set of varietal choices, orchard management, harvest practices, commercial outlets, and fruit fly management practices are identified: (1) Intensive farming systems supplying the export market with the variety Kent and using a large set of orchard management tools and harvest practices to eliminate fruit flies, (2) Extensive farming systems supplying various varieties of mangoes with a dominance of Kent to both export and domestic markets, with access to fruit fly management tools from public services, (3) Gathering farming systems characterized by zero-input, high varietal diversity, difficult market access, non-selective harvest practices, and fruit fly management rarely practiced. Conclusions. The farming systems form a gradient of increasing use of fruit fly management tools and inputs, access to extension services, and export market orientation. Their coexistence in the same territories significantly contributes to the inefficiency of the control measures against Bactrocera dorsalis. Our results support the premise that in Africa, the adoption of pest management tools is more deeply integrated into the practices of certain producers compared to others, due to internal and external factors influencing the operation.
Triptycene-like naphthopleiadene as a readily accessible scaffold for supramolecular and materials chemistry
Authors: Amin Md Khairul , Ye Chunchun , Pang Shuhua , Liu Yuancheng , Nichol Gary , McKeown Neil
Published: April 2024

Triptycene derivatives are used extensively in supramolecular and materials chemistry, however, most are prepared using multi-step synthesis involving the generation of a benzyne intermediate, which hinders production on a large scale. Inspired by the ease of the synthesis of resorcinarenes, we report the rapid and efficient preparation of triptycene-like 1,6,2’,7’-tetrahydroxynaphthopleiadene directly from 2,7-dihydroxynaphthalene and phthalaldehyde. Structural characterisation confirms the novel bridged bicyclic framework, within which the planes of the single benzene ring and two naphthalene units are fixed at an angle of ~120° relative to each other. Other diverse aromatic 1,2-dialdehydes and 2,7-disubstituted naphthalenes also provided similar triptycene-like products. The low cost of the precursors and undemanding reaction conditions allows for rapid multigram synthesis of 1,6,2’,7’-tetrahydroxynaphthopleiadene with product isolation achieved by simple filtration. The great potential for the use of the naphthopleiadene scaffold in supramolecular and polymer chemistry is demonstrated by the preparation of a very rigid novel cavitand, a microporous network polymer, and a solution-processable polymer of Intrinsic microporosity.

Published: April 2024

An air-stable B3,N3-containing dibenzobisanthene (8) was prepared in 29% yield by heating a 1,3,5-tri(azasilaanthryl)benzene (5) with BBr3 (180 °C). Under these conditions, the reaction does not stop after threefold SiMe2/BBr exchange but proceeds further via two rearrangement and two intramolecular C–H borylation steps. Some mechanistic details were unveiled by using smaller model systems and applying lower reaction temperatures. According to X-ray crystallography, compound 8 has a helically distorted scaffold. Due to its multiple resonance structure, it shows a narrow-band blue-green emission (λem = 493 nm; ΦPL = 84%; FWHM = 0.20 eV; THF); samples measured in PMMA gave prompt and delayed fluorescence lifetimes of 10.7 ns and 136 μs, respectively. The optical properties of 8 and of structurally related species were also investigated by quantum-chemical means: Most of these compounds exhibit a small energy gap ΔEST between the lowest excited singlet (S1) and triplet (T1) states and a non-negligible spin-orbit coupling (SOC) between S1 and T1/T2, demonstrating their potential as thermally activated delayed fluorescence (TADF) emitters
Unlocking Metal-Ligand Cooperative Catalytic Photochemical Benzene Carbonylation: A Mechanistic Approach
Authors: Crisanti Francesco , Montag Michael , Milstein David , Bonin Julien , von Wolff Niklas
Published: April 2024

A key challenge in green synthesis is the catalytic transformation of renewable substrates at high atom and energy efficiency, with minimal exergonicity (ΔG≈0). Non-thermal pathways, i.e., electrochemical and photochemical, can be used to leverage renewable energy resources to drive chemical processes at well-defined energy input and efficiency. Within this context, photochemical benzene carbonylation to produce benzaldehyde is a particularly interesting, albeit challenging, process that combines unfavorable thermodynamics (DG° = 1.7 kcal/mol) and the breaking of strong C-H bonds (113.5 kcal/mol) with full atom efficiency and renewable starting materials. Nevertheless, little progress has been made since this transformation was first reported, in 1980s and ’90s. By following a mechanistic approach, applying spectrophotochemical and computational tools, we sought to gain a detailed understanding of the non-thermal C-H activation of benzene using metal-ligand cooperative (MLC) PNP rhodium complexes. This allowed us to unlock catalytic MLC benzene carbonylation promoted by irradiation in the near-visible UV region (390 nm) for the first time.
Design of metal-organic frameworks using deep dreaming approaches
Authors: Cleeton Conor , Sarkisov Lev
Published: April 2024

Exploring the expansive and largely untapped chemical space of metal-organic frameworks (MOFs) holds promise for revolutionising the field of materials science. MOFs, hailed for their modular architecture, offer unmatched flexibility in customising functionalities to meet specific application needs. However, navigating this chemical space to identify optimal MOF structures poses a significant challenge. Tradtional high-throughput computational screening (HTCS), while useful, is often limited by a distribution bias towards materials not aligned with the desired functionalities. To overcome these limitations, this study adopts a ”deep dreaming” methodology to optimise MOFs in silico, aiming to generate structures with systematically shifted properties that are closer to target functionalities from the outset. Our methodology integrates property prediction and structure optimisation within a single interpretable framework, leveraging a specialised chemical language model augmented with attention mechanisms. Focusing on a curated set of MOF properties critical to applications like carbon capture and energy storage, our approach not only expands the selection of potential materials for HTCS but also opens new avenues for material exploration and development.
Scaling Laws for Optimal Herschel–Bulkley Yield Stress Fluid Flow in Self-Similar Tree-like Branching Networks
Authors: Garg Ashish
Published: April 2024

This study analyzes optimal flow conditions and structures in tree-like branching networks for yield stress Herschel–Bulkley fluids. We focus on maximizing flow conductance under volume constraints, assuming fully developed laminar flow in circular tubes. We propose a conjecture that if the tube-wall stress, remains the same in the network for all branches, then an optimal solution exists. We find that optimal network geometry depends on the number of branch splits $N$, and independent of the power-law index $n$ and the yield stress $\tau_y$. This optimal condition leads to an equal pressure drop across each branching level. Our results are validated with existing theory and extended to encompass shear-thinning and shear-thickening behaviors for any number of splits $N$ with and without yield stress. Additionally, we derive relationships between geometrical and flow characteristics for parent and daughter tubes, including wall stresses, length ratios. These findings provide valuable design principles for efficient transport systems involving yield stress fluids.
Asymmetric Synthesis of Chiral-at-Iridium Complexes through Pd-Catalyzed Kinetic Resolution
Authors: Chu Yun-Peng , Yue Xue-Lin , Liu De-Hai , Ma Jiajia
Published: April 2024

Metal-centered chirality has been recognized for over one century, and chiral-at-metal complexes where chirality is exclusively attributed to the metal center due to the specific coordination pattern of achiral ligands around the metal ion, has been broadly utilized in diverse areas of natural sciences. However, synthesis of these molecules remains constrained. Notably, while asymmetric catalysis has played a crucial role in the production of optically active organic molecules, its application to chiral-at-metal complexes is less straightforward. In this study, we introduce a kinetic resolution strategy employing a Pd-catalyzed asymmetric Suzuki-Miyaura cross-coupling reaction that efficiently produces optically active chiral-at-iridium complexes from racemic mixtures with high selectivity (achieving an s-factor of up to 133). This method enables further synthesis of complexes relevant to chiral metallodrugs and photosensitizers, underscoring the practical utility of our approach. Mechanistic studies suggest that reductive elimination is the turnover-limiting step over the Suzuki-Miyaura cross-coupling.

Beyond Learning by Videoconference: Findings from a Capacity-Building Study of Kosovan Teachers in the Post-Covid-19 Era
Authors: Uka Antigona , Morina Marigona , Kowch Eugene G.
Published: April 2024

During the Covid-19 pandemic, teachers were exposed to technology-enhanced learning as an emergency measure, yet despite decades of advancement in educational technology, the online learning experiences lacked deliberate design. Recent research highlights a gap concerning the design elements of online professional development and teachers’ needs for professional development in online education. Through this Design-Based Research, we therefore sought to offer an intervention in the form of a professional development programme built on the specific needs of teachers. In the present study, we report on the findings from this two-cycle, five-phase online professional development, taken by 90 practising high school teachers across Kosova. The study sheds light on teachers’ experiences and attitudes, as well as their readiness to take hands-on approaches to integrate, when available, complex technologies while leveraging the power of instructional design concepts in the post-Covid-19 era. The evidence indicates that, in order to develop effective teaching capacity in this environment, online professional development programmes must go beyond simple off-the-shelf technology (i.e., videoconferencing) applications. Similarly, our data shows that the inclusion of prior needs assessment in online and blended teacher development instruction positively impacts the development of teachers’ attitudes towards online education. The present paper provides specific recommendations for any innovative education system leader, teacher or scholar hoping to leverage new online learning knowledge to strengthen teacher practice.
The influence of external factors on the development of olfactory disorders in patients with the coronavirus disease 2019: an immunomorphological assessment
Authors: Shponka I.S. , Usova O.M.
Published: April 2024

Olfactory disorders of various etiology are an actual problem for a large part of the adult population of the world, according to the results of conducted research, their prevalence is about 19%. Hyposmia, anosmia, or dysosmia are considered the initial symptom in more than 25% of patients, but over time they affect more than 75% of the total number of patients. The main risk factors for the development of olfactory disorders are old age, male gender, head injuries, exposure to toxic substances and infectious diseases of the upper respiratory tract. The purpose of the study is to clarify the immunomorphological features of the olfactory epithelium of the nasal cavity of patients with the 2019 coronavirus disease, taking into account the background pathological changes in the structures of this area for a better understanding of the mechanisms of the development of olfactory dysfunction during infection with the SARS-CoV-2 coronavirus, depending on the presence of aggravating factors. Autopsy material was used for the study, namely fragments of the mucous membrane of the upper parts of the nasal cavity (olfactory epithelium), obtained from 20 deceased (8 women and 12 men) aged 53 to 86 years with a diagnosis of "Coronavirus disease 2019", confirmed by laboratory (polymerase chain reaction) and olfactory disorders of various degrees in the anamnesis. Mucosal samples were stained with standard hematoxylin and eosin and using an immunohistochemical method with antibodies to neuron-specific beta-III tubulin (TuJ-1), olfactory marker protein (OMP) and angiotensin-converting enzyme (ACE-2). The distribution of expression variants of receptors to OMP, TuJ-1 and ACE-2 in sections with signs of structural rearrangement and without signs of structural rearrangement at a magnification of 200x showed a significant difference (p<0.05): the number of OMP-positive cells in sections of the olfactory epithelium of the first group on average was 43.5 in the field of view (16.0-59.0), TuJ-1-positive cells in these sections – 44.5 in the field of view (17.0-61.0), ACE-2-positive cells – 37 in the field of view (14.0-55.0), and in the samples of the olfactory epithelium of the second group, the expression of receptors to OMP was only partially positive (18 (12.0-25.0) cells), TuJ-1 – 17.5 (14.0-24.0) cells, ACE-2 – 14 (9.0-18.0) cells. That is, the occurrence of olfactory disorders under the conditions of infection with the SARS-CoV-2 coronavirus can be both de novo and against the background of previous changes in the structural elements of the olfactory area of the mucous membrane of the nasal cavity. In this case, more vivid symptoms are likely, as well as criticality and irreversibility of pathological changes.

Published: April 2024

There is a close relationship between the condition of periodontal tissues and maloccluson. Timely functional diagnosis of changes that occur in periodontal tissues during orthodontic tooth movement is an important link in the prevention of periodontal diseases during orthodontic treatment. At the present time, special attention is paid to the problem of the influence of "war stress" on the maxillo-facial system of a human. Aim of the was work to study the changes in the state of periodontal supporting tissues in orthodontic patients according to periotestometry data during the last 15 years and in the conditions of martial law. Periotestometry of teeth in orthodontic patients was performed before the start of treatment with the Periotest device. All patients were divided into 4 groups according to the results in different years of the study. A total of 136 patients participated in the study. The biggest discrepancies when comparing periotestometry indicators were found between the data of the control and fourth group (in conditions of martial law) and an increase in the indicators of tooth mobility with a statistically significant difference of p<0.001 was proven. When comparing the indicators of groups 2 and 4 for most teeth, the statistically significant difference was from p<0.05 to p<0.001. When comparing the data of the tooth periotest in patients of groups 3 and 4, the indicators of tooth mobility also increased, although within the limits of statistical error (p>0.05). Over the past 15 years, a steady trend to increase in the mobility of all teeth on both jaws has been established. The largest changes in indicators were found in the dynamics of the fifteen-year follow-up (2008 to 2023) between people with an orthognathic bite of the control group and patients of the 4th group with malocclusion. Such changes may be related to the social and psycho-emotional stress that a person constantly experiences in conditions of martial law.

Published: April 2024

‘Despite the overwhelming evidence that we are not doing enough, there is still substantial resistance to talking about the possibility of living in a world where we temporarily overshoot 1.5°C.’

- Debra Roberts IPCC Co-Chair WGII AR6.

It is crucial for engineers to consider the implications of living in such a scenario, where common sense suggests that changes in critical natural systems may become irreversible and take urgent action to mitigate, respond and adapt to the threats posed by climate change.

This paper reflects on the role of engineers in climate action. It frames the challenges and opportunities for the profession to drive action, presenting examples of what is being done by the global engineering community. It sets out what will be needed from engineers in terms of innovation and changing mindsets, as well as the required skills, training, and capacity building. Finally, it argues that engineers should be bolder, louder, and more visible in advocating for climate action.
Efforts of Seismic Retrofit: The Future Challenge of Innoshima Bridge Beyond 40 Years of Service
Authors: Wang Hongxin , Kaneda Takao , Nishitani Masahiro , Kaneda Yasuaki
Published: April 2024

Innoshima Bridge, which was opened for traffic in 1983, is a three-span, two-hinged stiffening truss girder suspension bridge with a center span of 770 meters, featuring a double-deck structure with the upper level for motor vehicles and the lower level for bicycles and pedestrians. In response to large-scale earthquakes, the bridge is required to have the performance that limits seismic damage to a minimum and enables a swift rehabilitation of its functionality. The results of the seismic performance evaluation revealed damage to various members in the bridge. Therefore, it is decided to conduct seismic retrofit to the damaged members, such as installation of viscous dampers to reduce the seismic forces, addition and replacement of the structures around the wind tongues, and some other reinforcements. This paper presents a report on the seismic performance verification and retrofit design of Innoshima Bridge.
Developing computational design techniques to meet the increasing demand for more complex and sustainable bridges in Southeast Asia
Authors: Tapley Mike
Published: April 2024

The economic growth being seen in Southeast Asia is driving a significant investment in infrastructure, particularly in the major cities of the region. Constructing elevated highways and railways in an already congested urban environment requires innovative solutions, adopting prefabricated modular construction techniques to form curved/longer span bridges and viaducts.

The form of these bridges challenges the engineer, but the adoption of computational design techniques has granted the designer a key tool which permits agility in determining the arrangement while simplifying the approach to optimisation.

Computational design and prefabrication are closely aligned with the drive for sustainability in construction. Large sections of the bridges are fabricated in a factory or workshop based on the same 3-D model prepared for delivery of the design. The efficient use of materials and resources becomes intrinsic to the design process in finding the most suitable form and geometry. The manufacturing process leads to less site-based plant and a smaller workforce, working in a safer environment.

Investigation into the cause of cracks and the opportunity to refurbish steel Vierendeel railway bridges
Authors: Van Bogaert Philippe , De Backer Hans , De Pauw Bart
Published: April 2024

The oldest of a set of 3 steel Vierendeel bridges, carrying railway tracks across the canal from Mechelen to Leuven, shows various cracks, mainly in the vertical members. Material testing demonstrates that the early age steel characteristics show a large variation for strength, yield point, impact notch energy and chemical composition. A thorough investigation into both the ULS and the fatigue resistance does not imply these to be the cause of the cracks. Comparing the location of the cracks and those of the dynamiting and subsequent repair of the steel structure, reveals that the brittleness of the material must be the cause of the damage.
Weldability and post-welding fatigue strength of older railway bridges
Authors: Hirano Takahiro , Uchida Daisuke , Murakami Takanori , Hirabayashi Masaya
Published: April 2024

Steel railway bridges in Japan were built in large numbers following the standard design established in 1885, and many older steel bridges are still in service today. One standard structure is that of an I-beam bridge with an I-beam main girder. One typical damege of these bridges is the fatigue crack, occurring near the radius of the bottom edge of the girder plate just above the fulcrum, propagating parallel to the bottom flange in an axial direction. The authors considered welding as a countermeasure for such cracks, but the guidelines for repair and strengthening of steel railway bridges in Japan do not provide details for welding steel members of steel bridges manufactured before 1940. In this study, we examined six bridges constructed in different years between 1889 and 1932, and after confirming their weldability, fatigue tests were conducted on butt welded joints made from their steel material to confirm fatigue strength.
Sustainable salvation of deficient RC bridges by means of the UHPFRC Technology
Authors: Brühwiler Eugen
Published: April 2024

Structural application of impermeable, tensile strain hardening UHPFRC (Ultra-High-Performance Fibre-Reinforced-Cementitious Composite) follows two fundamental concepts: 1) Rehabilitation and strengthening of existing bridges by adding a layer of UHPFRC, and 2) Construction of new bridges in UHPFRC. This paper presents recent UHPFRC project realized in Switzerland using UHPFRC for the salvation of deficient reinforced concrete bridges, to improve their structural resistance and durability, as well as to extend their service duration. This allows to avoid the common practice consisting in the material and cost invasive “demolition-replacement” still largely applied. In this way, the UHPFRC Technology using a small amount of a novel building material provides a significant contribution towards sustainability since UHPFRC allows to preserve the existing bridge, its original materials and embodied energy.

Authors: Tibolt Mike , Ochojski Wojciech
Published: April 2024

The present paper gives insights in the current efforts of the steel industry to reach net-zero in 2050. Different steel solutions can be combined to achieve major savings in weight, material, building time and costs in construction and infrastructure projects. XCarb® recycled and renewably produced steel is already available on the market: by combining scrap and renewable electricity, it offers very low levels of CO2 emissions per ton of finished steel. Weathering steel can be used without any additional painting of the steel girders – preventing the detrimental impact of the paintings on the environment.

In the paper, the beneficial application of hot-rolled sections in weathering steel (Arcorox®460) and XCarb® is shown based on recently realised bridge projects in Poland.
Theoretical and legal foundations for assessing and compensating for harm to health in the physical sense: rejection of the formula “cannot be assessed, cannot be compensated” in domestic civil law
Authors: Kolesnichenko Ol'ga
Published: April 2024

This monograph sheds light on the problem of assessing and compensating for harm caused by damage to a citizen’s health. The author notes that when mentioning such harm, a modern civil scientist leads himself into a situation of “scientific dead end”, stating the special, extraordinary value of the basic intangible benefits of an individual and at the same time refusing to attempt to justify the parameters for its full and effective compensation. The stated approach fits into the formula “not to evaluate cannot be compensated”, constructed by analogy with the expression known to everyone from childhood “to execute cannot be pardoned”, where the comma is set according to the prevailing doctrinal views.
As a means of solving the identified problems, the author proposed a conceptual approach based on giving legal significance to manifestations of damage to a citizen’s health, considered in their direct, physical meaning. The monograph formulates the concept of physical harm and defines the prerequisites for constructing an optimal regime for legal regulation of its assessment and compensation.
Intended for teaching staff, researchers, individuals studying in educational institutions of higher education in legal specialties (areas of training), and anyone interested in the problems of the development of domestic tort law.

Recommender systems are designed to provide interesting information to users and assist them in making choices. With the help of a recommender system, users can feel more comfortable using an application. In this final project, we will implement a hybrid filtering method using two techniques: Word2Vec as the algorithm for content-based filtering and Restricted Boltzmann Machine for collaborative filtering. The Word2Vec algorithm will utilize a pre-trained model provided by Google, while the Restricted Boltzmann Machine algorithm will utilize the TensorFlow library. The dataset used for this project will be Movie Lens. The goal of this final project is to evaluate the accuracy and performance of the recommender system using various metrics such as Precision and Normalized Discounted Cumulative Gain.

The increased incidence of COVID-19 and HIV coinfection and the changes in the structure of HIV infection mortality during the pandemic necessitate an analysis of the causes of adverse outcomes in co-infection. Objective. To retrospectively analyze deaths in patients with COVID-19 and HIV coinfection in the stage of secondary diseases. Subjects and methods. The investigation involved the medical records of 56 patients with laboratorily confirmed COVID-19 and HIV infection who were hospitalized in January to December 2021. Results. A retrospective analysis of the medical reports showed that bilateral polysegmental pneumonia of mixed etiologies was the cause of death in the majority cases of COVID-19 and HIV coinfection in the stage of secondary diseases. Along with pneumonia, multiple opportunistic diseases and conditions, which aggravated the course of the underlying disease, were identified in these patients. Various somatic diseases are one of the reasons for the severe course of the coinfection. Conclusion. Stage IVB HIV infection was diagnosed in the majority of deaths. Bilateral polysegmental pneumonia of mixed etiologies was the most common cause of death in patients with COVID-19 and HIV coinfection in the stage of secondary diseases.

Among the protective factors of mixed saliva, antimicrobial peptides have received much attention. They have broad-spectrum antibacterial and antifungal activities. Synthetic peptides are found in hygiene products, such as mouthwashes, sprays, and toothpastes. According to their manufacturers, the use of these products helps prevent oral bacterial infections. Objective. To study the effect of toothpastes and mouth spray, which contain synthetic peptide complexes, on the physicochemical parameters of mixed saliva in order to substantiate their preventive antibacterial effect. Material and methods. Mixed saliva from patients was examined before and after the use of the synthetic peptide-containing spray and toothpaste. The following salivary physicochemical parameters (pH, surface tension, and base buffer capacity) were measured. Results. The peptide-containing spray and toothpaste caused changes in the oral fluid pH within the normal range, which assisted in maintaining oral homeostasis and in effectively exerting the functions of mixed saliva. When the spray or toothpaste was used, the base buffer capacity was slightly reduced, which suggested that the synthetic peptides were able to neutralize oral fluid acids and thereby to enhance the anti-inflammatory and antibacterial functions of mixed saliva. The surface tension of saliva was increased with the peptide-containing spray and that was decreased with the peptide-containing toothpaste. This effect indicated the active ability of the synthetic peptides to be absorbed into blood and to have a direct effect on cell metabolism at the site of lesion (when using the spray), as well as the ability of the complexes to integrate into the colloidal system of saliva, which enhanced its reparative and protective properties (when using the toothpaste). Conclusion. The study shows an increase in the antibacterial effect of mixed saliva when using oral hygiene products containing peptides, which contributes to the prevention of risk factors for inflammatory diseases of the oral mucosa and periodontium.

The article presents the results of duplex scanning of the common carotid arteries (CCA) and assessment of the structural and functional state of the vascular bed women with arterial hypertension (AH) with hypoestrogenemia. It was found that in patients with hypertension with a reduced level of estradiol, there is an expansion of the lumen of the CCA, a decrease in the speed of blood flow in the carotid arteries of a rectilinear course, without hemodynamically significant stenoses, which indicates structural and functional changes in the vascular wall. In the studied patients, in almost every third case, an inertial type of vasomotor reaction is detected before treatment, which indicates the contribution of dishormonosis to the progression of hypertension due to an increase in the stiffness of the vascular wall and the development of endothelial dysfunction. Combination therapy with BioDihydroquercetin and ACE inhibitor improves the structural and functional characteristics of the vascular wall of the CCA, has a positive effect on endothelial dysfunction, reduces the stiffness of the vascular wall of the arteries compared with patients taking ACE inhibitor monotherapy. The drug BioDihydroquercetin, produced with trade mark “Baikal Legend”, is a natural antioxidant, capillaroprotector, strengthens blood vessels, improves blood microcirculation, and is recommended to slow down the aging process of the body.

In developing countries, the most common pregnancy complication in pregnant women is anemia. The prevalence of anemia in pregnancy in Indonesia is still quite high, including in the East Java region. The problem of pregnant women at the Polindes Kaliwining in the Puskesmas Rambipuji Jember is that anemia status is not detected in each trimester of pregnancy. Mung beans contain iron which helps the formation of erythrocytes to increase hemoglobin levels. This community service aims to provide nutritional education and the use of mung beans in preventing anemia in pregnancy. The implementation of this service uses an outreach method using a video media approach. Apart from that, blood hemoglobin levels are also checked in pregnant women as an early detection of anemia. Iron supplementation is given in the form of blood supplement tablets to pregnant women. Furthermore, giving mung beans drinks as a complement to iron supplementation to prevent anemia in pregnancy. The educational approach via video has proven effective in increasing pregnant women's knowledge by 25% regarding anemia and the benefits of mung beans. Based on the results of examinations during this service activity, blood hemoglobin levels showed that 2 respondents experienced anemia in the third trimester of pregnancy. Regular Hb checks are very important during pregnancy. The combination of consuming blood supplement tablets and mung beans can reduce the incidence of anemia in pregnancy.
