Background: Mesenchymal stem cells (MSCs) are undifferentiated cells with the ability of multi-potency, pluripotency, and self-renewal. MSCs show great promise in cancer therapy due to their unique features. MSC secrete various cytokines with multifunctional properties, although their roles are unclear. Methods: We have investigated the influence of secreted cytokines from MSCs on KG-1 cells as a cell model of acute myeloid leukemia (AML). For this purpose, following the culture and characterization of MSCs, a trans-well system was used for co-culturing MSCs and KG-1. To determine apoptosis induction Ki/Caspase-3 assay was conducted for cultured KG-1 alone and in co-culture with MSCs (10:1) on day 7. In the following step, the protein was isolated from both groups (control and experimental) and western blotting was done for investigating the BAX and BCL-2 proteins expression. Results: It was found that MSCs significantly enhanced caspase-3 activity in KG-1 cells (P<0.05). Besides, A significant increase in protein expression of BAX was detected, while BCL-2 displayed a dramatic reduction (P<0.01). Conclusion: As a concluding remark, MSCs have a contributory role in the apoptosis of KG-1 cells that is mediated by Caspase-3, BAX, and BCL2 expression.
Recent Trends in Phytosome Nanocarriers for Improved Bioavailability and Uptake of Herbal Drugs
Authors: Hari Priya Vijayakumari Mahadevan , Kumaran Alaganandam
Published: February 2023

Phytopharmaceuticals or herbal drugs have a significant therapeutic impact on healthcare systems. Though herbal extracts and their active constituents show excellent pharmacological in vitro effects, they still have indigent in vivo biological effects because of their considerable molecular weight and low lipid solubility, leading to low systemic availability. Phytosome is a novel approach for overcoming the drawbacks of conventional delivery methods of herbal actives. The phospholipids, mainly phosphatidylcholine, form a bond with herbal extracts or actives, forming a herb-lipid complex. The encapsulation of herbal actives with phospholipid allows an effective tool for the delivery to the affected area with enhanced pharmacological effect. Moreover, the amphiphilic nature of the phospholipid provides a good hydrophilic-lipophilic balance, thereby improving a better dissolution profile in the lipid-rich membranes of the gastrointestinal tract. This review focuses on the various phytosome nanocarriers to improve herbal medication bioavailability and uptake—recent trends in their industrial applicability, and applications in clinical management for various diseases, including other challenges.

Family values development level in modern teenagers
Authors: Volot Nikita V.
Published: February 2023

This article is devoted to the study of the phenomenon of family values. Based on the analysis of foreign and Russian research on this topic, the concept of “family valuesˮ is clarified and the structure of the phenomenon under study in the context of adolescent development is proposed. On the basis of the identified structure, an author's methodology was developed to determine the level of development of family values of teenagers. With its help, a study was conducted, the purpose of which was the determination of level of development of family values in modern teenagers. The testing was attended by pupils of the 8th forms of the municipal budgetary educational institution of the City of Kostroma “Gymnasium No. 15ˮ in the amount of 115 people (50 boys, 65 girls). The average age of the respondents was 13.5 years. Diagnostics showed that the general level of formation of family values has predominantly average values, which determines the potential for the effective formation of family values in teenagers. It was also found that teenage boys and girls have significant differences in the level of formation of individual components of family values. This allowed us to assume that further pedagogic influence, which forms family values in teenagers, should be of a differentiating character, which consider the identified sex differences.

Authors: Kuznetsova Irina V. , Burakova Galina Yu. , Troshina Tatiana L. , Gollay Anna W.
Published: February 2023

This article discusses the problem of implementing interdisciplinary connections between a school course in Mathematics and other natural science disciplines at a secondary school as topical means of developing functional literacy among pupils. The mechanisms of interdisciplinary connection of Mathematics with other disciplines are listed. As a means of interdisciplinary communication of Mathematics with other disciplines, there can be the interaction of pupils in the information educational environment to search for new knowledge, to identify properties of a generalised character, to solve practice-oriented problems, to combine knowledge from various general education subjects, to teach Computer Science based on the transfer and generalisation of knowledge from related subjects. The article provides examples of practice-oriented tasks that illustrate the relationship of Mathematics with such secondary school disciplines as Computer Science, Biology, Geography, and Physics. It is noted that when solving such problems, schoolchildren learn various aspects of multi-level practice-oriented activities, including the use of computer capabilities and the global Internet. It is shown that mathematical constructions and their analogues are found even in areas of knowledge quite distant from exact sciences, such as literature, for example. It is substantiated that it is the solution of interdisciplinary problems that forms the meta-skills necessary for everyday life in pupils.
Teachingworkers’ resource-based thinking psychology
Authors: Kashapov Mergalyas M. , Surina Natalya Lv.
Published: February 2023

The article discusses the psychological features of the resource capacity of teaching worker, necessary for the implementation of professional activities. To study resource-based thinking, a comparative analysis of pedagogic (N = 110) and medical (N = 106) workers was carried out. The criterion for such a division included belonging of these workers to the type of socionomic professions. In an empirical study, data collection was carried out using the methods of “Thinkingresourcefulness assessment” (Irina Serafimovich, Yelena Medvedeva, Natal’ya Surina); “Individual well-being subjective diagnostics” (Rail’ Shamionov, Tat’yana Beskova); “5 Facet Mindfullness Questionnaire” (Ruth A Baer, Gregory T. Smith, Jaclyn Hopkins, Jennifer Krietemeyer, Leslie Toney; adaptation: Nadezhda Yumartova, Nataliya Grishina); “Diagnostics of the level of emotional burnout” (Viktor Boyko). In the course of the study, the hypothesis was verified that the formation of resource-based thinking is significantly influenced by the peculiarities of the lifestyle and organisation of the subject's work activity. It has been established that there are differences in the peculiarities of the manifestation of resource-based thinking among pedagogues and medical workers. The resource-based of professional thinking among the socionomic type professions’ representatives is closely interrelated with the work experience, the peculiarities of the professionalisation process. Lifestyle features, a variety of hobbies, leisure organisation features, mum's education and the number of hobbies in childhood influence the development of resource-based thinking. Resource-based thinking is considered as a professionally important quality and is revealed as one of the key metacognitive characteristics that ensure both professional success and psychological well-being. A high level of development of resource-based thinking positively affectsthe level of subjective well-being of an individual. The importance of resource-based thinking as a factor in the prevention of emotional burnout is substantiated.
Basic Principles of Managing Oncological Patients with Chronic Coronary Syndromes
Authors: Суджаева О.А.
Published: February 2023

В статье представлена часть обзора Рекомендаций Европейского общества кардиологов по кардиоонкологии (2022), посвященная ведению пациентов с хроническими коронарными синдромами (ХКС). На разных этапах лечения рака (при постановке диагноза, проведении специализированного лечения и в разные сроки после него) ведение пациентов с ХКС имеет ряд особенностей. Следует учитывать повышенный риск развития кардиологических осложнений у пациентов с ХКС и онкологией на всех этапах лечения и динамического наблюдения за выжившими после рака, в том числе получивших лечение в детском возрасте. Немаловажной частью ведения данной категории пациентов является оценка лекарственного взаимодействия между основными антиангинальными препаратами и средствами, используемыми для лечения рака. Ведение онкологических пациентов с ХКС зачастую требует мультидисциплинарного подхода с привлечением врачей-специалистов онкологов, химиотерапевтов, интервенционных кардиологов, кардиохирургов и клинических фармакологов. Указанные аспекты нашли отражение в настоящей статье.

The article presents a part of the review of the European Society of Cardiology Guidelines for Cardio-Oncology (2022) on the management of patients with chronic coronary syndromes (CCS). At different stages of cancer treatment (during diagnosis, specialized treatment and at different times thereafter), the management of patients with CCS has a number of special features. The increased risk of developing cardiac complications in patients with CCS and oncology should be taken into account at all stages of treatment and dynamic monitoring of cancer survivors, even those who received treatment in childhood. An important part of the management of this category of patients is the assessment of drug interactions between the main antianginal drugs and drugs used to treat cancer. The management of cancer patients with CCS often requires a multidisciplinary approach involving medical specialists: oncologists, chemotherapists, interventional cardiologists, cardiac surgeons, and clinical pharmacologists. These aspects are reflected in this article.
"Arrhythmic" Mitral Valve Prolapse
Authors: Трисветова Е.Л. , Ушакова Л.Ю.
Published: February 2023

Пролапс митрального клапана описан в 70-х годах прошлого века как доброкачественное заболевание, вместе с тем в последующие годы исследователи сообщали о случаях желудочковых нарушений ритма сердца и внезапной сердечной смерти у пациентов с пролабированием створок митрального клапана. В настоящее время описан фенотип «аритмического», или «злокачественного», пролапса митрального клапана с характерными демографическими, электрокардиографическими и выявленными при визуализации сердца признаками. «Аритмический» пролапс митрального клапана часто возникает у женщин молодого возраста с нарушениями реполяризации на электрокардиограмме, с дизъюнкцией и систолическим скручиванием (curling) митрального кольца, фиброзом папиллярных мышц и задне- или нижнебазальной стенки левого желудочка, являющихся морфологическим субстратом желудочковых аритмий. Среди патофизиологических механизмов, обусловливающих появление электрической нестабильности сердца, выделяют вызванные механическим стрессом изменения рефрактерных периодов желудочков, электрофизиологические изменения в волокнах Пуркинье, гипермобильность фиброзного кольца и аномальную тракцию папиллярных мышц. Знание о факторах риска развития жизнеугрожающих аритмий и внезапной сердечной смерти и их своевременное выявление позволит выбрать эффективные методы лечения и улучшить прогноз пациентов с «аритмическим» пролапсом митрального клапана.

Mitral valve prolapse was described in the 1970s as a benign disease, however, in subsequent years researchers reported cases of ventricular arrhythmias and sudden cardiac death in patients with mitral valve prolapse. A phenotype of "arrhythmic" or "malignant" mitral valve prolapse has now been described, with characteristic demographic, electrocardiographic, and cardiac imaging features. "Arrhythmic" mitral valve prolapse often occurs in young women with repolarization disorders on the electrocardiogram, with disjunction and systolic "curling" (twisting) of the mitral ring, fibrosis of the papillary muscles and the posterior or inferior basal wall of the left ventricle, which are the morphological substrate of ventricular arrhythmias. Among pathophysiological mechanisms responsible for electrical instability in the heart are mechanical stress-induced changes in ventricular refractory periods, electrophysiological changes in Purkinje fibers, hypermobility of the fibrous ring and abnormal traction of papillary muscles. Awareness of risk factors for life-threatening arrhythmias and sudden cardiac death and their timely detection should allow choosing effective treatment methods and improving the prognosis for patients with "arrhythmic" mitral valve prolapse.

Authors: Stefanova Petya
Published: February 2023

The importance of Public Healthcare as a science originates from the measures in an integrated manner, targeted at the health of the public through prevention and extending life in good health. Home health care for elderly people with chronic illnesses and functional dependence is one of the priorities of the social politics of Bulgaria, through the creation of regulations for the interaction when organising and planning the support that supplies their health and social needs. in the competencies of nurses is the provision of health and social care for people with chronic diseases and functional dependence. The covid 19 pandemic has presented challenges in implementing nursing interventions. Due to the declared global pandemic on 19.03.2020 of COVID-19, many countries including Bulgaria, introduced strict measures for maximal isolation and social distancing with the aim of reducing transmission to the minimum. This presented an array of challenges for the teams, carrying out the activities for patronage care in the homes of the care receivers. Objective: To review and analyze the impact of the COVID 19 pandemic on changes in the daily activities of health care providers in the municipalities of Burgas region. Methods: documentary - research and analysis of information; sociological-anonymous survey; statistically. Results: developed and implemented additional module “Patronage Care +” with expansion of the target group of users and services provided; provided personal protective equipment and disinfectants to the multidisciplinary team providing care; not all project managers have provided antigenic tests for the teams; communication between the team and the GPs of the users - difficult; periodic briefings for compliance with anti-epidemic measures; Of the 41 nurses, 19.51% were quarantined with complaints and positive PSR tests - without hospitalization, and of the home nurses 26.23%. Vaccinated nurses - certainly 2 / project managers are not familiar /; ineffective medical waste management. Conclusion: The provisioning of health and social services and care is absolutely necessary for the maintenance of the quality of life of people with chronic illnesses with functional dependencies and under the existing pandemic situation; The care receivers are willing to accept alternative approaches for realizing the activities, providing them with quality of life even with their chronic ailments and degree of disability; The managers and coordinators of project “Patron care” have the capabilities and the resources to maintain the quality of the offered integrated health and social service; The absence of medical nurses in the teams of some municipalities in the Burgas region negatively affects the carrying out of activities of the project. The high percentage of nurses placed under quarantine and home nurses supports the tendency for lack of emergency and periodic instruction, i.e. unsatisfactory activity of the occupational medicine services.
SYNTHESIS OF THREATS AND RISKS OF CYBER SECURITY OF MONTENEGRO - THE VULNERABILITY ASPECT OF INFORMATION COMMUNICATION INFRASTRUCTURE
Authors: Mujević Mersad
Published: February 2023

That there are no untouchables and that cyber threats are entering Montenegro through the big doors, is indicated by the hacker attack on the Government of Montenegro. Fortunately, the hackers did not get hold of confidential data, but their act itself caused a serious act of endangering state security, especially because they breached the system that is networked with all state bodies. It was not the first time in 2022 that hackers broke into Government IC systems and state and private companies and organizations. Experts from the IT sector have been warning about the vulnerability of the system for a long time, but not loudly enough to be taken seriously. Let’s also mention the attack on Montenegro on the eve of joining NATO, where Montenegro was under increased cyber attacks, and the Ministry of Defense says that it is similar today.Cyber is no longer the world of gamers and geeks, it is increasingly becoming a prefix for terrorism, crime, and other types of threats (Kazerić 2017). Internet trade and the use of electronic services such as e-government are also on the rise. To the global trend, almost everything that was only tangible and materialized in the real world is moving to the virtual community. This brings with it many advantages, but also disadvantages, and one of them is certainly the vulnerability of critical information and communication infrastructure and the danger of cyber attacks. In such circumstances, the issue of security partially shifts the focus to cyber, that is, cyber security. Precisely for this reason, it is necessary to take a critical look at the existing information and communication infrastructure and analyze the existing threats and risks brought by the modern, cybernetic age. The synthesis of threats and risks is necessary so that we can adequately face them and predict the difficulties that may come our way, which could have significant consequences for national security.
