Rearrangement of bone tissue occurs during the orthodontic treatment of tooth crowding due to the processes of resorption and apposition, the ability to influence these processes will allow to reduce the complications of orthodontic treatment purposefully. The aim: to investigate the processes of resorption and osteogenesis of jaw bone tissue during the orthodontic treatment of children with nonremovable devices. Materials and methods of the study. The research of mineral density of jaws has been held among 19 orthodontic patients between the ages of 12-14 with a tooth crowding. Dental sanation and professional oral hygiene have been made in children before the orthodontic treatment. Mineral density of bone tissue, volumetric part of bone trabecules, has been determined by estimation of spread rate of ultrasound waves of upper and lower jaws. Results. Conclusions. The received results confirm the data, in the dynamics of active orthodontic treatment, especially in the beginning, the processes of bone resorption dominates, while in a period of stabilization the synthesis of bone tissue is more active.
Keywords: jaw bone tissue, crowding of teeth, ultrasound wave, echo osteometry

No full textThe Doctoral Thesis was developed at Baltic International Academy, Latvia. Defence: at the public session of the Doctoral Committee of Doctoral Committee of Economics and Business on 7th July 2022 at 11.00 online via Zoom platform.The key principle of electricity market design is the maximisation of public welfare. In the context of rational electricity consumption, social welfare is the sum of consumer surplus, supplier surplus and congestion rents in order to maximise the benefits to society. For decades, the importance of balancing supply and demand has been emphasised in discussions on the security of the electricity sector. It has been reasonably assumed that electricity demand is inelastic, mainly by studying supply potential. However, the current understanding of supply and demand in the electricity system needs to address the three main challenges of European energy policy: sustainability, security of supply and competitiveness, while guaranteeing fairness in energy distribution. The aim of the research is to develop a conceptual framework for the integration of renewable energy sources and consumer involvement, based on the technology of a Demand Response aggregator – an information and technology company – in the Latvian electricity sector. The Thesis consists of an introduction, four chapters, conclusions, recommendations and a bibliography. The introduction explains the actuality of the research topic, defines the aims and objectives of the research, its subject and object, puts forward the research hypothesis, and determines the scientific novelty and practical significance of the research. In the first and second chapters, a theoretical and methodological framework, economic and institutional foundations and peculiarities of Demand Response in the energy sector, electricity price factors, the new role of electricity end-users and the possibilities of optimising demand response are provided. In the third chapter, the author analyses the macroeconomic and physical indicator trends of the energy sector, the renewable energy sources and electricity system prices, calculates approximate dependence formulae and coefficients of determination; develops a methodology for a comprehensive analysis of correlation and regression dependence of physical and system price indicators of the electricity sector based on an appropriate adaptation of classical mathematical models, and contributes to the literature on the impact of the state aid on the electricity market. In the fourth chapter, the author has proposed and developed a new two-level technical model for optimisation of demand response services, which proposes to solve the problem of reducing electricity consumption in the first stage and, in the second stage, to solve the optimisation problem of which group of active consumers' loads to disconnect in case of electricity shortages, thus, to respond to electricity market prices. The main text of the Thesis is 155 pages. The bibliography contains 137 sources. Additionally, 48 tables, 31 figures and 2 annexes are included in the Thesis

Реализация программы Европа 2020 –построение инновационной экономики стран Европейского Союза (ЕС) – является приоритетным направлением ЕС. В Латвии, как в среднем и в ЕС, 99,8 % предприятий являются МСП. Поиск индикаторов, влияющих на создание инновационной экономики и включение в инновационную среду предприятий малого и среднего бизнеса является проблемой не только для Латвии, стран Балтии, но и в целом для всего ЕС. Тайвань является одним из «азиатских тигров», который совершил огромный экономический скачок из аграрного государства в индустриальное. Выпуск в 2016 году ряда высокотехнологических продуктов, таких как: материнские платы – 89,7 % мирового рынка, кабельное CPE-оборудование 84,5 % и ноутбуки – 83,5 % мирового рынка, ставят страну в ряд стран с инновационной экономикой. Поэтому анализ опыта Тайваня в построении инновационной экономики заслуживает дополнительного изучения и реализации его в других странах.Для исследования автор использовал следующие методы: контент анализ – источники информации были систематизированы, а численные показатели обработаны, оценены и интерпретированы, и статистический анализ – метод корреляции Пирсона, Спирмена и Тау Кендалла. С помощью этих методов отобраны показатели, влияющие на количество МСП. В ходе проведенного теоретического анализа автор сформулировал преимущества малого и среднего бизнеса, провел поиск показателей, влияющих на малые и средние предприятия и вовлечение их в инновационную среду Тайваня.Установление линейной взаимосвязи и использование корреляционного анализа с использованием программы SPSS позволило автору найти взаимосвязь между показателями:количество исследователей (в эквиваленте полной занятости);ежегодные статьи в индексе научного цитирования (SCI);ежегодный отчет по инженерному индексу (EI);количество малых и средних предприятий;общая занятость малых и средних предприятий;количество зарегистрированных патентов.Использование взаимосвязанных индикаторов решает важную экономическую задачу – повышение уровня жизни населения за счет инноваций. Оценка данных показателей в странах ЕС с помощью эконометрических методов позволит реализовывать инновационную политику государств.Об'єктом дослідження є малі і середні підприємства (МСП) Тайваню. Реалізація програми Європа-2020 – побудова інноваційної економіки країн Європейського Союзу (ЄС) – є пріоритетним напрямком ЄС. У Латвії, як в середньому і в ЄС, 99,8 % підприємств є МСП. Пошук індикаторів, що впливають на створення інноваційної економіки і включення в інноваційну середу підприємств малого і середнього бізнесу є проблемою не тільки для Латвії, країн Балтії, а й в цілому для всього ЄС. Тайвань є одним з «азіатських тигрів», який зробив величезний економічний стрибок з аграрної держави в індустріальну. Випуск в 2016 році низки високотехнологічних продуктів, таких як: материнські плати – 89,7 % світового ринку, кабельне CPE-обладнання 84,5 % і ноутбуки – 83,5 % світового ринку, ставлять країну в ряд країн з інноваційною економікою. Тому аналіз досвіду Тайваню в побудові інноваційної економіки заслуговує додаткового вивчення і реалізації його в інших країнах.Для дослідження автор використовував такі методи: контент аналіз – джерела інформації були систематизовані, а чисельні показники оброблені, оцінені і інтерпретовані, і статистичний аналіз – метод кореляції Пірсона, Спірмена і Тау Кендалла.

Infusion of freshly isolated autologous bone marrow derived mononuclear cells prevents endotoxin-induced lung injury in an ex-vivo perfused swine model
No full textIntroduction\ud
The acute respiratory distress syndrome (ARDS), affects up to 150,000 patients per year in the United States. We and other groups have demonstrated that bone marrow derived mesenchymal stromal stem cells prevent ARDS induced by systemic and local administration of endotoxin (lipopolysaccharide (LPS)) in mice.\ud
\ud
Methods\ud
A study was undertaken to determine the effects of the diverse populations of bone marrow derived cells on the pathophysiology of ARDS, using a unique ex-vivo swine preparation, in which only the ventilated lung and the liver are perfused with autologous blood. Six experimental groups were designated as: 1) endotoxin alone, 2) endotoxin + total fresh whole bone marrow nuclear cells (BMC), 3) endotoxin + non-hematopoietic bone marrow cells (CD45 neg), 4) endotoxin + hematopoietic bone marrow cells (CD45 positive), 5) endotoxin + buffy coat and 6) endotoxin + in vitro expanded swine CD45 negative adherent allogeneic bone marrow cells (cultured CD45neg). We measured at different levels the biological consequences of the infusion of the different subsets of cells. The measured parameters were: pulmonary vascular resistance (PVR), gas exchange (PO2), lung edema (lung wet/dry weight), gene expression and serum concentrations of the pro-inflammatory cytokines IL-1β, TNF-α and IL-6.\ud
\ud
Results\ud
Infusion of freshly purified autologous total BMCs, as well as non-hematopoietic CD45(-) bone marrow cells significantly reduced endotoxin-induced pulmonary hypertension and hypoxemia and reduced the lung edema. Also, in the groups that received BMCs and cultured CD45neg we observed a decrease in the levels of IL-1β and TNF-α in plasma. Infusion of hematopoietic CD45(+) bone marrow cells or peripheral blood buffy coat cells did not protect against LPS-induced lung injury.\ud
\ud
Conclusions\ud
We conclude that infusion of freshly isolated autologous whole bone marrow cells and the subset of non-hematopoietic cells can suppress the acute humoral and physiologic responses induced by endotoxemia by modulating the inflammatory response, mechanisms that do not involve engraftment or trans-differentiation of the cells. These observations may have important implications for the design of future cell therapies for ARDS
Assessment of the factors influencing the digitalization of economies in the Baltic States
No full textReikšminiai žodžiai: Skaitmeninimas; Skaitmeninė ekonomika; Baltijos šalys. Keywords: Digitalization; Digital economy; Baltic StatesDigitalization of the world economy is accompanied by a comprehensive digital transformation of all business processes. However, the speed of digital transformation varies across countries. The aim of the research was to identify the main factors influencing the pace of digitalization of economies in the three Baltic States. The research is based on Eurostat’s data from 2014 to 2020. For evaluating the factors that may impact the level of digitalization of economies in Estonia, Latvia and Lithuania the authors carried out a Pearson correlation analysis, using SPSS software. The research results indicate that in the context of the digitalization of the economy, the factors directly linked to the level of GDP are the number of specialists involved in the R&D sector and use of the Internet for banking operations. The findings of the study are supposed to be used for the development of a policy for business digital transformation in the Baltic States
