Abstract
In this article, the author made an attempt to present and analyze issues related to global environmental problems, and in particular, the role of carbon dioxide in global warming. Well-known facts and unexpected findings are intended to awaken in the reader a critical attitude towards the prevailing beliefs in these matters.
From the point of view of a chemist, the reality of extracting CO2 from air and converting it back into fuel is assessed. Simple energy calculations make it possible to assess the ability of "green" energy to replace carbon and influence the climate warming process. And finally, the key proposals are presented from the point of view of a technologist, since it is technologists who make real and implement the most daring discoveries and projects of scientists and inventors.
Key words: Climate change, carbon dioxide, CO2 carbon, greenhouse gases, renewable energy

Abstract
The authors, in a study on 25 outbred Wistar white rats weighing 180-200 g, determined the effect of Lamidana (a product from sea brown algae) on the structural-functional continuum, that is, the correlation of the functional activity of the liver parenchyma and its structural characteristics. Methods. The detoxifying function of the liver was studied by the duration of sleep of animals due to the action of anesthesia - intraperitoneal administration of sodium thiopental (estimate the rate of metabolism of thiopental, carried out by the cytochrome-P-450-dependent monooxygenase system of hepatocytes). The structural and functional state of the liver parenchyma was assessed according to the study of histological preparations. The results of the studies showed that under the influence of the external application of "Lamidin" in the test rats, the liver1s detoxification function is enhanced (significantly significant decrease in the duration of sleep of animals). At the same time, structural signs of increased functional activity of hepatocytes are determined in the parenchyma. Conclusions. The authors believe that "Lamidan", due to the peculiarities of its chemical composition, enhances the metabolic and functional activity of hepatocytes but does not damage the correlative relationships between the structure and function of hepatocytes.
Keywords: product from brown algae; liver; structural-functional continuum

Abstract
The state of insulin resistance was reproduced in white Wistar rats by injection of alloxan in the original dosage. This state was characterized by increased level of glucose during glucose tolerance test. Two-week internal application of aqueous solution of Poltava bishofite prevented disruption of the basal level of glucose in the blood of rats. The obtained data served as an experimental justification of application of bishofite in clinical practice on patients with the syndrome of insulin resistance affected by nonalcoholic fatty liver disease. Decrease in concentration of total cholesterol, triglycerides and tendency to decrease in low density lipoprotein were noted after one month of application of the Poltava bishofite by these patients. Glucose level of the blood serum in the treatment process did not change significantly but insulin level decreased significantly, i.e. effectiveness of insulin activity increased. This resulted in a decrease of HOMA-IR index especially for patients with baseline hyperinsulinemia with insulin level decreasing in 1.6 times during treatment.
Keywords: aqueous solution of Poltava bishofite, insulin resistance.
Реферат
У белых крыс линии Вистар было воспроизведено состояние инсулинорезистентности путем введения аллоксана в оригинальной дозировке. Это состояние характеризовалось повышением уровня глюкозы при проведении теста толерантности к глюкозе. Двухнедельное внутреннее применение водного раствора Полтавского бишофита предотвращало нарушение базального уровня глюкозы в крови крыс. Полученные данные послужили експериментальным обоснованием применения бишофита в клинической практике у больных с синдромом инсулинорезистентности на фоне неалкогольной жировой болезни печени. У этих больных после месячного приема Полтавского бишофита было установлено уменьшение концентрации общего холестерина, триглицеридов, тенденция к уменьшению липопротеидов низкой плотности. Уровень глюкозы сыворотки крови в процессе лечения существенно не изменился, но уровень инсулина значительно снизился, т.е., эффективность инсулиновой активности повысилась. Это привело к снижению индекса НОМА-IR особенно у больных с исходной гиперинсулинемией, у которых уровень инсулина в процессе лечения снизился в 1,6 раза.
Ключевые слова: водный раствор Полтавской бишофит, резистентность к инсулину

No full textВ работе приведены результаты исследований пар трения «бронза БрБ2 — сталь 45». Для определения зависимости влияния нагрузочно-скоростных режимов трибовзаимодействия была использована пластичная приработочная комплексная литиевая смазка третьего поколения OIMOL KL R 2 с ультрадисперсной алмазографитовой шихтой с концентрацией наноалмазов 0,5 %. Исследования показали, что в условиях граничного трения пары «бронза — сталь» модифицирование смазочного материала добавками ультрадисперсной алмазографитовой шихты эффективно при давлениях свыше 20 МПа. Установлено, что модифицированную смазку достаточно применять только на стадии приработки.= The paper presents the results of studies of friction pairs “bronze БрБ2 (BrB2) — steel 45”. To determine the dependence of the influence of the load-speed modes of tribo-interaction, a plastic running-in complex lithium lubricant of the third generation OIMOL KL R 2 was used with an ultrafine diamond-graphite charge with a concentration of nanodiamonds of 0.5 %. Studies have shown that under the boundary friction conditions of the “bronze — steel” pair, the modification of the lubricant with additives of ultrafine diamond-graphite charge is effective at pressures over 20 MPa. It has been established that it is sufficient to use the modified lubricant only at the running-in stage

Abstract
The article presents data on the effect of silicon-containing mineral waters (MW) and their artificial analogues with the corresponding content of metasilicic acid on the state of the stomach wall in the modeling of gastritis in white rats. It was established that the use of MW with different content of metasilicic acid has a unidirectional, positive effect on the course of gastritis. MW with greater mineralization, molarity and high content of methacrylic acid completely eliminate inflammation and moderately stimulate reparative processes.
In the application of MW with less mineralization, molarity and lower content of metasilicic acid, there were definitive inflammation manifestations, but the manifestations of reparative processes were more pronounced. The same trend was observed with the use of artificial analogues - model solutions on distilled water with the corresponding content of metasilicic acid. It is determined the same restorative in the direction, but much weaker corrective effect than the corresponding MW. The important component of the corrective action of these silicon MW when used in animals with gastritis is determined by the peculiarities of the macro component composition and the proportion of the main macro components - Na +, K +, Mg2 +, Ca2 +, НСО3, Cl-, SO42- and, to a lesser extent, silicon content.
Keywords: silicon-containing mineral waters, gastrointestinal tract, metasilicic aci
Non-technical skills for neurosurgeons: An international survey
Get PDFIntroduction: Neurosurgery is considered a technically demanding specialty; nonetheless, it also requires non-technical skills (NTSs) to reach mastery. Research question: This study seeks to understand how important NTSs are perceived by neurosurgeons across diverse roles and socio-economic backgrounds. The objective is to identify key NTSs and explore their role in surgical precision, teamwork, and collaboration. Material and method: An international survey involving 372 neurosurgeons from various socio-economic and cultural contexts was conducted. The extensive sample and inclusive methodology provide a comprehensive perspective on the perceived importance of NTSs in neurosurgery. Results: The survey results highlight the universal significance of NTSs among neurosurgeons. Attention to detail, humility, and self-awareness are considered essential for surgical precision, effective teamwork, and collaboration. The findings underscore the necessity for integrated training programs that combine NTSs with technical skills. Discussion and conclusion: The study emphasizes the importance of effective training methods such as simulations, mentorship, and role-playing in equipping neurosurgeons to navigate the complexities of their profession. Future research should focus on optimizing teaching methods for NTSs, comparing traditional courses, online modules, and hybrid training programs. Addressing the global disparity in neurosurgical care, particularly in low- and middle-income countries, is crucial for improving patient outcomes worldwide
