Comparative assessment of the role of TMPRSS2 and ACE-2 receptors in the development of olfactory disorders in infection with coronavirus SARS-CoV-2
Authors: Usova O.M.
Published: April 2024

Background. Today, evidence of the impact of the SARSCoV-2 coronavirus not only on the cells of the olfactory epithelium, but also on the components of the deeper parts of the olfactory system (olfactory bulbs and the olfactory area of the cerebral cortex), indicates the expression of proteins by the cells of the olfactory epithelium that contribute to further penetration of the virus. An urgent problem is the lack of comprehensive studies of the role of morphological and immunological features of various parts of the olfactory system in the occurrence of olfactory disorders and insufficient understanding of the relationship between their duration and the localization of cells affected by the SARS-CoV-2 coronavirus. The оbjective of the study is to clarify the feasibility of studying the role of TMPRSS2 receptors and comparing it with the role of ACE-2 receptors localized on the components of the olfactory epithelium in the development of olfactory disorders in the Coronavirus Disease 2019 caused by SARS-CoV-2. Methods. This study was performed using autopsy material, namely fragments of the mucous membrane of the upper parts of the nasal cavity (olfactory epithelium), obtained from 10 deceased (6 women and 4 men) aged 53 to 79 years with a laboratory-confirmed diagnosis of "Coronavirus Disease 2019" (polymerase chain reaction) and olfactory disorders of various degrees in the anamnesis. Mucosal samples were stained both with hematoxylin and eosin, and using an immunohistochemical method with antibodies to transmembrane serine protease-2 (TMPRSS2) and angiotensin-converting enzyme (ACE-2). Results. As a result of this study, the number of OMP-positive cells in sections of the olfactory epithelium was on average 46.5 in the field of view at 200x magnification (35.0-59.0), ACE-2-positive cells - 38.5 in the field of view at magnification 200x (21.0-55.0), TMPRSS2-positive - 81 in the field of view at 200x magnification (63.0-96.0). Conclusion. Studying the role of TMPRSS2 and ACE-2 receptors localized on olfactory epithelial cells in the development of olfactory disorders in the 2019 coronavirus disease caused by SARS-CoV-2 will provide a better scientific understanding of the development of disease-specific symptoms.
Connective tissue cells of the skin: heterogeneity of fibroblasts and general properties of their subpopulations
Authors: Maievskyi O.Ye. , Tverdokhlib I.V.
Published: April 2024

Directing of experimental and clinical research requires integration of information on morphological and functional features of organs and tissue structures. One of the examples of such integration is the analysis of the histophysiology of the skin, in particular dermal fibroblasts – a mandatory cellular component of the dermis. They not only synthesize and organize the components of the extracellular matrix of the dermis, but also interact with each other and with other types of cells, playing a decisive role in the regulation of skin histophysiology. Other resident cells include epidermal, vascular, and nerve cells. In addition, the skin contains various cells of hematogenous origin. They contain a constitutive population of dendritic cells and a more dynamic population of leukocytes, which includes monocytes (macrophages), neutrophils, and lymphocytes. Dermal fibroblasts are a dynamic and diverse population of cells whose functions in skin in many respects remain unknown. Normal adult human skin contains at least three distinct subpopulations of fibroblasts, which occupy unique niches in the dermis. Fibroblasts from each of these niches exhibit distinctive differences when cultured separately. Specific differences in fibroblast histophysiology are evident in papillary dermal fibroblasts, which reside in the superficial dermis, and reticular fibroblasts, which reside in the deep dermis. Both of these subpopulations of fibroblasts differ from the fibroblasts that are associated with hair follicles. Fibroblasts engage in fibroblast-epidermal interactions during hair development and in interfollicular regions of skin. They also play an important role in cutaneous structural transformations.

Published: April 2024

Tasavvuf edebiyatı, ekseriyetle Anadolu sahasında olmak üzere çeşitli tarikatlare, meşrep ve zümrelere mensup sufi şairlerin ana teması tasavvuf olan ve manzum, mensur, karışık şekilde telif ettiği eserlerin oluşturduğu bir saha olarak tanımlanmakla birlikte esasında sufinin yaratıcısıyla olan ilişki biçimlerini söze döktüğü, bunu yaparken çeşitli ifade yollarını seçtiği, kendine has üsluplar geliştirdiği ve hatta sözün sınırlarını zorladığı bir alandır. Tasavvuf edebiyatının klasikleri yazılana dek süregelen dönem içinde bu edebiyatın ilk nüveleri doğal olarak yavaş yavaş biriken bir yapıya sahiptir. Hem şifahi hem yazınsal müktesebat zamanla artıp belli bir yeküne ulaştığında kurucu tabir edilen şahıslar ve telifler yoluyla tasavvuf edebiyatı sistematik bir tarzda düzenlenmiştir. Tasavvuf edebiyatının ele alındığı çalışmalar mevcutsa da son on yılda kayda değer yeni bir telif yapılmamıştır. Kenan Mermer ise Tasavvuf Edebiyatı-İsimler, Kavramlar ve İlişkiler Ağına Metodik Bir Yaklaşım (9-13. yüzyıl) isimli kitabında konuyu kronolojik açıdan derleyen ve birbirini malumat bakımından tekrarlayan çalışmaların ötesine geçerek tabiri caizse bir mana kazısı yapmak gayreti göstermiştir. Böylece isimlerin ve dolayısıyla eserlerin birbirleri arasındaki ilişkiler ağının izi sürülerek dikkate değer bir çalışma ortaya konulmuştur. Mermer, tasavvuf edebiyatının 9-13. yüzyılları ihtiva eden bölümünü ele almış, tasavvuf kaynaklarına başvururken muteber çeviri eserlerin yanısıra orijinal metinlerini de kullanmıştır. Yazarın eserdeki konuları ele alış tarzı esasında metodolojik açıdan da mühim bir örnektir zira bu bakışla edebiyat denildiğinde karşımıza çıkan büyük ve soyut tarihi alanda birtakım izahlar yapabilmek için kelime ve kavramlara şahısların ilişkiler ağı merceğinden bakmayı deneyen farklı bir yol takip etmiştir. Mermer’in çalışması, tasavvuf edebiyatını siyak/sibak bağlamı gözeterek bütün sistematik unsurları, kavramları, kurucu şahıs ve eserleri; çeviri tashihleriyle hülasa etmesi bakımından dikkate değerdir.
Vertex-weighted $(k_{1},k_{2})$ $E$-torsion Graph of Quasi Self-dual Codes
Authors: Pilongo Jupiter , Paleta Leonard Mijares , Benjamin Philip Lester P.
Published: April 2024

In this paper, we have introduced a graph $G_{EC}$ generated by type-$(k_{1},k_{2})$ $E$-codes which is $(k_{1},k_{2})$ $E$-torsion graph. The binary code words of the torsion code of $C$ are the set of vertices, and the edges are defined using the construction of $E$-codes. Also, we characterized the graph obtained when $k_{1}=0$ and $k_{2}=0$ and calculated the degrees of every vertex and the number of edges of $G_{EC}$. Moreover, we presented necessary and sufficient conditions for a vertex to be in the center of a graph given the property of the code word corresponding to the vertex. Finally, we represent every quasi-self dual codes of short length by defining the vertex-weighted $(k_{1},k_{2})$ $E$-torsion graph, where the weight of every vertex is the weight of the code word corresponding to the vertex.

Published: April 2024

This work takes an interesting diversion, revealing the extraordinary capacity to determine the precise number of primes in a space tripled over another. Exploring the domain of K-almost prime numbers, this paper provides a clear explanation of the complex idea. In addition to outlining the conditions under which odd K-almost prime numbers must exist, it presents a novel method for figuring out how often odd numbers are as 2-almost prime, 3-almost prime, 4-almost prime, and so on, up to a specified limit n. The work goes one step further and offers useful advice on how to use these approaches to precisely calculate the prime counting function, π(n). Essentially, it offers a comprehensive exploration of the mathematical fabric, where primes reveal their mysteries in both large and small spaces.

This approach allows for the analysis of network properties and the identification of key proteins driving biological processes. Our analysis revealed RPS27A as a central proteinwithin the network, associated with diverse functions related to ribosome biogenesis, translation, cell growth, apoptosis, and cancer progression. This suggests that RPS27A may have multiple functions in cancer development and progression, including in MAPK signaling pathways. Importantly, our study uniquely identifies RPS27A as a central hub in lung cancer PPI networks, shedding light on its pivotal role in disease pathogenesis. Additionally, we identified a central network zone enriched with proteins involved in key signaling pathways, presenting novel insights into potential therapeutic targets for lung cancer treatment. Pathway enrichment analysis further highlighted functional specialization across network zones, providing a comprehensive understanding of the intricate interplay between biological pathways in lung cancer progression. This study underscores the multifaceted roles of central proteins like RPS27A within lung cancer’s PPI network and the network’s potential for pinpointing therapeutic targets, presenting a novel perspective on the intricate network of molecular interactions driving lung cancer pathogenesis.

Published: April 2024

Terrorist activity in the Sahel region has been on the increase for almost a decade.  Groups advocating extremist ideologies with a political or religious base are carrying out attacks against states with the aim of imposing a totalitarian ideology, sometimes against a backdrop of political crisis and famine. In this state of crisis and sometimes communal conflict, it is questionable whether ideological terrorism can really be eradicated in the Sahel. In this study, we develop a model of the dynamics of ideological terrorism based on the terrorism situation in the Sahel. In particular, this model incorporates popular resistance to terrorism through the class of volunteers for the defense of the homeland, but we also take into account the indoctrination of certain sections of the population vulnerable to fanatical ideology. We estimate $\mathcal{R}_0$ , the number of elementary replications of extremist behavior, which enables us to predict the evolution of extremism. We also identify four thresholds $\mathcal{R}_1$, $\mathcal{R}_2$, $\mathcal{R}_3$ and $\mathcal{R}_4$ of sufficient conditions for the eradication of ideological terrorism and brigandage. A multi-objective optimal control of a counter-terrorism strategy is also presented. Finally, we perform a numerical simulation of the analysis and control results to test our hypotheses.

Published: April 2024

This paper derives the bivariate version of the extended standard U-quadratic (eSU)  distribution using the method of compounding or pseudo family of distributions. The joint probability and cumulative distribution functions of the derived distribution are obtained and it is observed that the said distribution can generate bivariate shape with the following properties: $(i)$ $X$ and $Y$ have bathtub shapes; $(ii)$ $X$ has constant and $Y$ has bathtub shapes; and $(iii)$ $X$ has inverted bathtub and $Y$ has bathtub shapes. Moreover, some properties of the derived distribution such as the marginal distribution, conditional distributions, conditional moments, product and ratio moments are derived. Further, the maximum likelihood estimation is performed to estimate the parameters of the derived distribution. Also, a simulation study is carried out to evaluate the behavior of the estimates of the parameters. Moreover, we derive a new bivariate Kumaraswamy distribution and use it to simulate bivariate data with $X$ and $Y$ having bathtub shapes. Furthermore, A new bivariate version of the Cubic Transmuted Uniform (CTU) distribution is also derived. Finally, the proposed Bivariate eSU distribution is applied to simulated data and compared with the said Bivarite Cubic Transmuted Uniform distribution. The result shows that the proposed Bivariate eSU distribution provides a better fit for the said simulated dataset as compared with the Bivariate CTU distribution.

Published: April 2024

The paper focuses on the Lotka-Volterra function in its discrete form. The purpose of the study was to determine the fixed points of the function. The study employs the Banach Fixed Point Theorem and Contraction Mapping in Metric Space on the function to demonstrate the uniqueness of the fixed points and its continuous stability after several iterations, using the fixed points as the initial conditions. The study has shown that $(0,0),\left(0,\frac{\alpha-1}{\beta}\right),\left(\frac{1+\gamma}{\delta},0\right)$ and $\left(\frac{1+\gamma}{\delta},\frac{\alpha-1}{\beta}\right) $are the fixed points of the function, with the initial pair serving as a trivial one and the other three solely depending on the parameter values for the behavior of the function. The outcome of the limit points of the function as the fixed points after several iterations forms a fixed orbit structure of the function, irrespective of the value of the parameter. The study also showed the uniqueness of the fixed points, demonstrating the stability and continuity of the function in its steady state.
Certified Vertex Cover of a Graph

Let $G$ be a graph. Then $Q \subseteq V(G)$ is called a certified vertex covering set of G if $Q$ is a vertex cover of $G$ and every $x \in Q$, $x$ has zero or at least two neighbors in $V(G)\setminus Q$. The certified vertex cover number of $G$, denoted by $\beta_{cer}(G)$, is the minimum cardinality of a certified vertex cover of $G$. In this paper, we investigate this parameter on some special graphs and on the join of two graphs. We characterize certified vertex covering sets in these graphs and we use these results to derive the simplified formulas for solving the said parameter. Moreover, we present some bounds and properties of this parameter.
On the McShane-Dunford-Stieltjes Integral and McShane-Pettis-Stieltjes Integral
Authors: Omayan Develin , Flores Greig Bates
Published: April 2024

This paper combines the McShane-Stieltjes integral and Pettis approaches by utilizing Pettis' definition, which coincides with the Dunford integral rather than the version applicable to weakly measurable functions with Lebesgue integrable images. In this way, another integration process without measure theoretic standpoint will be introduced. To this end, we will define the McShane-Dunford-Stieltjes integral and McShane-Pettis-Stieltjes integral in Banach Space and provide its simple properties such as the uniqueness, linearity property of both  the integrand and integrator, additivity and formulate the Cauchy criterion of these integrals.  In addition, the existence theorem of McShane-Dunford Stieltjes integral will also be presented.

Published: April 2024

This paper introduces and investigates several new classes of sets called P-α-open sets, Psemiopen sets, P-preopen sets, and P-β-open sets within the framework of primal topological spaces. Their properties and relationships with other open set generalizations are studied through examples. Additionally, the concepts of PR-sets and PRα -sets are defined and their characteristics examined. Also, the notions of P-α-continuous, P-semicontinuous, P-precontinuous and P-β-continuous mappings are initiated and their features and main characterizations determined. A new class of sets called Ψ_P -sets is also introduced in primal topological spaces using the ΨP -operator. Their properties and relationships between Ψ_ P -sets, α-open, semi-open, and pre-open are investigated. Theorems on arbitrary unions and finite intersections of Ψ_P are discussed.

Authors: Gonzaga Elvie Barzo
Published: April 2024

This descriptive research investigated the opportunities, attitude, and engagement in Continuing Professional Development (CPD) activities among elementary school teachers in the Province of Iloilo for the school year 2023-2024. The population comprised of elementary school teachers, with 380 participants selected through random sampling. Data were collected through an online survey utilizing a structured, researcher-made, validated and reliability tested questionnaire. The results revealed significant differences in the opportunities for CPD activities across congressional districts. Additionally, significant variations were found in teachers' attitude towards CPD activities based on their educational attainment. Furthermore, significant differences were observed in the level of teachers' engagement in CPD activities concerning both educational attainment and congressional district. However, no significant differences were found when teachers were classified according to their age, sex, school level, and school size. This study concludes that, while opportunities and attitude significantly influence engagement in CPD activities, their significant differences vary when they were classified according to their educational attainment and congressional district. Hence, it is imperative to consider these when designing CPD programs for elementary school teachers in the Province of Iloilo. Tailoring CPD opportunities and strategies is highly recommended to address the specific needs and preferences of teachers based on their educational backgrounds and geographic locations. Moreover, further research is warranted to explore additional variables that may influence teachers' engagement in CPD activities and to assess the long-term effectiveness of CPD programs in enhancing teaching quality and student outcomes.
