Authors: Kang Shuaizhi , Jia Xia , Zhao Yonghua , Ao Yong , Ma Chaoqun
Published: October 2024

The exploitation of coal resources has caused problems such as ground deformation, affecting the ecological environment. Spatiotemporal varying characteristics between land subsidence and ecological environmental quality (EEQ) are an important research hotspot. Using the SBAS-InSAR method, 64 Sentinel-1 images were utilized to monitor land subsidence in the Shenfu mining area, one of China’s largest coal source regions. And the remote sensing ecological index (RSEI) was used to monitor and evaluate EEQ of the Shenfu mining area. Global and local spatial autocorrelation methods were used to assess the spatial aggregation degree and change patterns over time. Spatial Econometric Models were employed to explore the impacts of land subsidence on EEQ. The results showed the following: (1) The average RSEI values in the Shenfu mining area were 0.531, 0.488, and 0.523 in 2016, 2018, and 2020, respectively; there was a slight downward trend in EEQ. The permanent scatter (PS) point deformation rate ranged from −353.40 mm/year to +246.24 mm/year, with average deformation rates of 0.1642, 0.2181, and 0.2490 mm/year, respectively. (2) There was a significant correlation and spatial agglomeration effect between land surface subsidence and EEQ. Low–high, high–low, and low–low clusters were the main types of relationships, indicating that land subsidence primarily has a negative spatial impact on the ecological environment. (3) The relationship between land subsidence and EEQ varied spatially in the Shenfu mining area at 500 × 500 grid units. This research can provide scientific guidance for disaster prevention and sustainable development in mining areas by considering long-term differences in ecological environmental quality and its correlation with land subsidence.

Authors: Xu Xiaofeng , Dong Youming , Huang Xianjin
Published: October 2024

The Rurality Index is an important reference for the formulation of rural development strategies and policies, but the evaluation of the rurality of megacities based on the township scale is relatively limited. Based on the perspective of spatial governance, this study constructed the evaluation index system of Shanghai’s rurality and carried out the evaluation of Shanghai’s rurality at the township scale from 2005 to 2020. The article adopts the MGWR model to analyze the driving effects of five key driving factors (the proportion of foreign population, per capita industrial output value, public finance revenue, social fixed asset investment, and rail transit coverage), and adopts the Geo-Detector model to analyze the interactive driving effects of two factors. The results indicate that the rurality index of megacities and townships as a whole shows a weakening trend, and the above factors have a predominantly negative impact on rurality, with differences in the intensity of the impact in different periods. There is an obvious interactive additive effect between the factors. When formulating policies for township development, government departments need to take into account the functional positioning of the region and comprehensively adopt targeted policies on population, industry, transportation, finance and investment to regulate and guide the transformation or sustainable development of the countryside.

Published: October 2024

In the face of carbon emissions reduction efforts, which are a common but differentiated global responsibility, it is crucial to explore the potential synergistic path between economic growth and carbon emissions reduction. This study integrates economic growth management and carbon emissions into a theoretical framework, based on city-level panel data from 2005 to 2019 in the Yangtze River Delta and the fixed effects model. We explore the impact of economic growth targets on urban carbon emissions. Then, we explore the mechanism by which economic growth target affects carbon emissions with the mediation effect model and moderation effect model. The results reveal that economic growth targets are beneficial for carbon reduction, and innovation development from innovation transformation is an important mechanism driving carbon emissions reduction, but the effects of different innovation outputs exhibit notable variations. In addition, marketization and industrial structure affect the relationship between economic growth targets and carbon emissions. The heterogeneity analysis reveals substantial spatial and temporal differences. Based on the realities of developing countries’ ongoing economic targets, this study provides a new explanation for the relationship between government policies and carbon emissions, establishing a scientific basis for policymakers to formulate strategic green development policies.

Urban and peri-urban expansion significantly influences the spatial pattern of cities and surrounding zones. This study examines the spatial changes in green infrastructure components, specifically focusing on mature forests, short forests, and agricultural and grass lands from 1986 to 2021, using satellite imagery. Two landscape ecology indexes, the percentage of landscape (PLAND), and the largest patch index (LPI), were applied. PLAND provides insights into the proportion of habitat types, capturing overall extent, while LPI elucidates their spatial configuration. The research is conducted in a specific context of increasing urbanization and peri-urbanization in Kisangani city, DR Congo. The findings reveal a decline in both mature and short forests, respectively, from 1986 to 2021, and from 2006 to 2021 alongside a continuous expansion of agricultural and grass lands at the landscape scale. Moreover, the spatial pattern of mature and short forests exhibited significant variations across urban, peri-urban, and rural zones. In the context of 2021, in urban and peri-urban zones, mature forests account for less than 1% of the 2.25 km2 plots, against more than 35% in certain rural plots. Similarly, larger patches of mature forest in urban and peri-urban zones cover less than 0.5% of the 2.25 km2 plots, whereas they exceed 20% in rural zones. From 1986 to 2021, both mature and short forests experienced significant decline and fragmentation, particularly in urban and peri-urban zones, while agricultural and grass lands increased significantly in peri-urban and rural zones. These results raise concerns regarding the functions, services, and opportunities provided by mature and short forests in the context of global change. They also highlight the need for urban planning in Kisangani to prioritize green infrastructure preservation, focusing on maintaining forest connectivity and preventing further fragmentation. Policies should promote sustainable land use in peri-urban zones to achieve a balance between urban expansion and the provision of essential ecosystem services, thereby enhancing long-term resilience.

Tropical rainforests are of vital importance to the environment, as they contribute to weather patterns, biodiversity and even human wellbeing. Hence, in the face of tropical deforestation, it becomes exigent to quantify and assess the contribution of ecosystem services associated with tropical rainforests to the environment and especially to the people. This study adopted a nuanced approach, different from traditional economic valuations, to estimate the water-related ecosystem services (WRESs) received by the people from 2010 to 2020 in the Hainan Tropical Rainforest National Park (HTRNP). The study focused on water yield, soil conservation, and water purification using InVEST, the SCS-CNGIS model, and spatial analysis. The results show (1) significant land cover changes within the HTRNP, as forest decreased by 4433 ha and water bodies increased by 4047 ha, indicating the active presence of human activities. However, land cover changes were more pronounced within the 5 km buffer area around the HTRNP, suggesting the effectiveness of the tropical rainforest conservation efforts in place. (2) The water yield of the HTRNP in the years studied decreased by 307.03 km3, based on the water yields in 2010 and 2020, which were 5625.7 km3 and 5318.7 km3, respectively. (3) Change detection showed that runoff mitigation in the rainforest has a negative mean (−0.21), indicating a slight overall decrease in soil conservation and runoff mitigation in the rainforest from 2010 to 2020; however, the higher curve number indicates areas susceptible to surface runoff. (4) The ecological effectiveness of water purification to absorb and reduce nitrogen load was better in 2020 (145,529 kg/year), as it was reduced from 506,739 kg/year in 2010, indicating improved water quality. (5) Population growth is more pronounced in areas with high water yields. Overall, the proposed framework has shown that the water yield potential of the HTRNP can meet the water consumption demands of people and industries situated within the buffer area. However, analysis of the study shows that it does not meet the crop water requirements. This study provides insights for decision makers in identifying potential beneficiaries and the essence of effective area-based conservation measures, and the proposed framework can be applied to any area of interest, offering a different approach in ecosystem services assessment.
China’s Urban Regeneration Evolution from 1949 to 2022: From the Perspective of Governance Mode
Authors: Zhu Yujia , Song Jusheng , Bai Yunxi
Published: October 2024

Urban regeneration has played an important role in Chinese successful urban economic development and is constantly evolving along with the changes in the demands of urban development. However, there have been relatively few studies on urban regeneration evolution. In order to explore the relationship between the evolution of urban regeneration and urban development in China, this paper divides China’s urban regeneration into four stages from the perspective of governance mode, namely, unitary governance, binary governance, tripartite governance, and pluralistic co-governance. It is found that the evolution of urban regeneration is closely related to the core contradictions in the process of urban development, and the development challenges at each period are often caused by the urban regeneration governance mode in the pervious phase. The evolution of urban development and urban regeneration governance mode presents the phenomenon of interaction. Based on the understanding of urban regeneration evolution, this study points out the problems that need to be solved in China’s urban regeneration in the future with suggestions, and the hope is that this study can provide experiences for the urban regeneration development of other developing countries.

Authors: Đorđević Zlatković Miljana R. , Stojanović Nikola M. , Zlatković Dragan B. , Randjelović Pavle J. , Radulović Niko S.
Published: October 2024

An essential oil dominated by germacrene D (19.3% by GC) was isolated from the fresh fruit of Amorpha fruticosa L. (Fabaceae). Agglomerative clustering and k-means clustering were employed to compare the composition of the oil with the existing literature data, suggesting that the A. fruticosa used in this study represents a new chemotype. The essential oil was evaluated for its antinociceptive activity using the acetic acid-induced writhing test in rats at doses of 400, 200, and 100 mg/kg. All tested doses reduced the number of writhes induced by the intraperitoneal injection of acetic acid. The 400 mg/kg dose of the oil demonstrated a 54.4% inhibition, which was statistically different from the positive control, aspirin, which showed 90.2% inhibition at a dose of 200 mg/kg. Since the injection of acetic acid produces the release of prostaglandins, such as PGE2α and PGF2α, as well as sympathetic nervous system mediators in peritoneal fluids, the results suggest that the inhibition of prostaglandin release might represent one of the possible mechanisms of action exerted by the oil.
New Advances in Iberian Medieval Agriculture: Plant Remains from the Islamic Site of Castillo de Valtierra (Navarre, Northern Spain)
Authors: Peralta-Gómez Antonio , Peña-Chocarro Leonor , Lorenzo Jiménez Jesús
Published: October 2024

There has been a notable lack of archaeological research into the medieval period in Iberia, particularly in comparison to earlier periods. Consequently, the majority of our current understanding of agricultural practices and plant food sources in this region is derived from textual sources. However, there has been a notable increase in interest in archaeobotanical studies in medieval contexts over the past decade. In this context, this paper presents the results of a study of plant remains from Castillo de Valtierra (Navarre), with the objective of providing insights into agricultural practices and dietary habits during the Islamic period. In this area (the Ebro Valley), the Islamic period is divided as follows: Emiral period 756–929 AD, Caliphal period 929–ca.1012 AD, Taifal period ca.1012–1119 AD. This period was followed by the Christian period from 1119 AD onwards. Samples were collected from a variety of contexts in a systematic manner. A total of 2574 remains were recovered, and 57 taxa were identified. The findings of this study demonstrate that the community that inhabited Valtierra was primarily engaged in agricultural activities and had access to a diverse range of crops sourced from various productive areas, including cereal fields, home gardens, and forests.
Relationships Between Organic Acid Metabolism and the Accumulation of Sugars and Calcium in Fruits of Cerasus humilis During Different Development Stages
Authors: Zhang Li , Zhang Jie , Guo Jinli
Published: October 2024

Cerasus humilis fruit is known for its high acidity, surpassing that of most other fruits. The metabolism of organic acids in these fruits significantly influences sugar and calcium accumulation. However, research on this metabolic process is limited. This study investigates the organic acid metabolism and the accumulation patterns of sugars and calcium during the development of Cerasus humilis fruits. Using low−acid and high−acid varieties from Inner Mongolia, we compared organic acid components and the activity of relevant metabolic enzymes during fruit maturation. We also measured the content and proportions of various sugars and calcium forms, performing correlation analyses. Throughout the development and ripening of Cerasus humilis fruits, organic acids, sugars, and calcium exhibited consistent patterns of change across the two acidity types. Malic acid emerged as the most significant organic acid, while fructose was the primary sugar, and active calcium was the dominant calcium component. Correlation analyses indicated that malic acid and total acid positively correlated with sugar and water−soluble calcium content, negatively regulating other calcium forms. Conversely, NADP−ME, citric acid, and oxalic acid negatively correlated with sugars and water−soluble calcium, while positively affecting other calcium forms. In conclusion, the metabolism of organic acids during the development and maturation of Cerasus humilis fruits is closely linked to the accumulation of sugars and calcium. Malic acid, primarily regulated by NAD−MDH and NADP−ME, promotes the accumulation of sugars and water−soluble calcium but inhibits other calcium forms, while citric and oxalic acids inhibit sugar accumulation and promote non−water−soluble calcium forms.

SO2 fumigation treatment (commonly known as sulfur treatment, ST) is a key method in the postharvest preservation of imported and exported fresh longan fruits, effectively reducing pericarp browning and enhancing color. Nonetheless, distinctive aromas, often referred to as “sulfur flavor”, may develop in the aril during the extended preservation period. This study employed “Caopu” longan as the test material and patented SO2-releasing paper (ZL201610227848.7) as a treatment to perform a 35-day low-temperature (5 °C) storage of the fruit. The changes in glucosinolates (GSLs) and associated metabolites in the aril of treated fruit (ST) were examined utilizing ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) detection and widely targeted metabolomics technology. The findings indicated that following 35 days of storage, nearly all control (CK) fruit pericarp turned to brown, resulting in an edible fruit rate of 75.41% and a commercial fruit rate of 0%. In contrast, the treated (ST) fruit demonstrated an edible fruit rate and a commercial rate of 99.44%, while the pericarp color changed from dark yellow-brown to light earthy yellow. The sulfur-containing metabolites identified in longan fruit aril predominantly consist of amino acids and their derivatives (60.44%), followed by alkaloids (15.38%), nucleotides and their derivatives (1.10%), and other types (23.08%), which include GSLs. SO2 treatment significantly reduced the content of oxidized glutathione in fruit aril but increased the content of GSLs and related amino acids and their derivatives. Via screening, 19 differential sulfur-containing metabolites were obtained between ST and CK, including 11 GSLs. The identified differential metabolites of GSLs were all increased, primarily comprising aliphatic GSLs, such as 1-hydroxymethyl glucosinolate, 2-Propenyl glucosinolate (Sinigrin), and 4-Methylsulfinylbutyl glucosinolate (Glucoraphanin). Pathway analysis showed that these differential metabolites were mainly involved in coenzyme factor synthesis, cysteine and methionine metabolism, and amino acid synthesis, among other pathways. To the best of our knowledge, this is the first study to reveal the causes of the special flavor of longan aril after SO2 treatment, which is a great concern for longan consumers. Moreover, this study provides a scientific basis for exploring the reasons and mechanisms for the development of the sulfur flavor in the SO2-treated fruits during postharvest storage.

Published: October 2024

Hydroponic greenhouses and vertical farms provide an alternative crop production strategy in regions that experience low temperatures, suboptimal sunlight, or inadequate soil quality. However, hydroponic systems are soilless and, therefore, have vastly different bacterial microbiota than plants grown in soil. This review highlights some of the most prevalent plant growth-promoting bacteria (PGPB) and destructive phytopathogenic bacteria that dominate hydroponic systems. A complete understanding of which bacteria increase hydroponic crop yields and ways to mitigate crop loss from disease are critical to advancing microbiome research. The section focussing on plant growth-promoting bacteria highlights putative biological pathways for growth promotion and evidence of increased crop productivity in hydroponic systems by these organisms. Seven genera are examined in detail, including Pseudomonas, Bacillus, Azospirillum, Azotobacter, Rhizobium, Paenibacillus, and Paraburkholderia. In contrast, the review of hydroponic phytopathogens explores the mechanisms of disease, studies of disease incidence in greenhouse crops, and disease control strategies. Economically relevant diseases caused by Xanthomonas, Erwinia, Agrobacterium, Ralstonia, Clavibacter, Pectobacterium, and Pseudomonas are discussed. The conditions that make Pseudomonas both a friend and a foe, depending on the species, environment, and gene expression, provide insights into the complexity of plant–bacterial interactions. By amalgamating information on both beneficial and pathogenic bacteria in hydroponics, researchers and greenhouse growers can be better informed on how bacteria impact modern crop production systems.

Published: October 2024

The aboveground biomass (AGB) of summer maize is an important indicator for assessing crop growth status and predicting yield, playing a significant role in agricultural management and decision-making. Traditional on-site measurements of AGB are limited, due to low efficiency and a lack of spatial information. The development of unmanned aerial vehicle (UAV) technology in agriculture offers a rapid and cost-effective method for obtaining crop growth information, but currently, the prediction accuracy of summer maize AGB based on UAVs is limited. This study focuses on the entire growth period of summer maize. Multispectral images of six key growth stages of maize were captured using a DJI Phantom 4 Pro, and color indices and elevation data (DEM) were extracted from these growth stage images. Combining measured data such as summer maize AGB and plant height, which were collected on the ground, and based on the three machine learning algorithms of partial least squares regression (PLSR), random forest (RF), and long short-term memory (LSTM), an input feature analysis of PH was carried out, and a prediction model of summer maize AGB was constructed. The results show that: (1) using unmanned aerial vehicle spectral data (CIS) alone to predict the biomass of summer maize has relatively poor prediction accuracy. Among the three models, the LSTM (CIS) model has the best simulation effect, with a coefficient of determination (R2) ranging from 0.516 to 0.649. The R2 of the RF (CIS) model is 0.446–0.537. The R2 of the PLSR (CIS) model is 0.323–0.401. (2) After adding plant height (PH) data, the accuracy and stability of model prediction significantly improved. R2 increased by about 25%, and both RMSE and NRSME decreased by about 20%. Among the three prediction models, the LSTM (PH + CIS) model had the best performance, with R2 = 0.744, root mean square error (RSME) = 4.833 g, and normalized root mean square error (NRSME) = 0.107. Compared to using only color indices (CIS) as the model input, adding plant height (PH) significantly enhances the prediction effect of AGB (aboveground biomass) prediction in key growth periods of summer maize. This method can serve as a reference for the precise monitoring of crop biomass status through remote sensing with unmanned aerial vehicles.
Modeling the Benefits of Electric Cooking in Ecuador: A Long-Term Perspective
Authors: Guayanlema Veronica , Martínez-Gómez Javier , Fontalvo Javier , Espinoza Vicente Sebastian
Published: October 2024

The study quantifies the benefits of expanding electric cooking in the residential sector in replacement of liquefied petroleum gas (LPG), including economic savings and the avoided emissions resulting from this transition, viewed through the perspective of a long-range optimal energy system model developed for the Ecuadorian energy system under the LEAP (Long-range Energy Alternative Planning) framework. In Ecuador, electricity generation is predominantly based on hydropower obtained from run-of-the-river schemes. The model results indicate that a sectorial-level policy to promote electric cooking reduces the use of LPG per annum, which consequently leads to reductions in greenhouse gas emissions. Additionally, the electric cooking scenario also complements the Ecuadorian vision of reducing deforestation and reaching carbon neutrality. Furthermore, the subsidies to LPG will be reduced, improving energy sovereignty. Finally, the paper discusses the effects and implications of this policy implementation over the nationally determined contributions (NDC).

Published: October 2024

Objective: COVID-19 vaccine-neutralizing antibodies provide early data on potential vaccine effectiveness, but their usefulness depends on study reliability and reporting quality. Methods: We systematically evaluated 50 published post-vaccination neutralizing antibody studies for key parameters that determine study and data quality regarding sample size, SARS-CoV-2 infection, vaccination regimen, sample collection period, demographic characterization, clinical characterization, experimental protocol, live virus and pseudo-virus details, assay standardization, and data reporting. Each category was scored from very high to low or unclear quality, with the lowest score determining the overall study quality score. Results: None of the studies attained an overall high or very high score, 8% (n = 4) attained moderate, 42% (n = 21) low, and 50% (n = 25) unclear. The categories with the fewest studies assessed as ≥ high quality were SARS-CoV-2 infection (42%), sample size (30%), and assay standardization (14%). Overall quality was similar over time. No association between journal impact factor and quality score was found. Conclusions: We found that reporting in neutralization studies is widely incomplete, limiting their usefulness for downstream analyses.

Изучено содержание и роль адипокина жировой ткани – апелина – у 49 больных с деформирующим остеоартрозом (ДОА) и при его сочетании с ожирением (32 из всех обследованных). Установлено достоверное увеличение данного показателя у больных с ожирением и ДОА. Выявлена прямая корреляционная зависимость между уровнем апелина и индексом массы тела (r=0,43), апелином и инсулинорезистентностою (r=0,46) и обратная – cдлительностью анамнеза по ДОА (r=-0,61). У больных с ДОА и нормальной массой тела уровень апелина имел лишь тенденцию к повышению при сравнении с показателями контроля. Учитывая роль апелина в организме – катаболизм хрящевой ткани – данный показатели можно использовать с диагностической целью.

Studed the content and role of adipose tissue adypokin`s – apelin in patients with osteoarthritis (OA) and when it is combined with obesity (32 out of all surveyed). Determined a significant increase in this indicator in patients with obesity and OA. A direct correlation between the level of apelin and body mass index (r=0,43), apelin and insulin resistance (r=0,46) and reverse – with long history on DOA (r=-0,61). Patients with OA and normal weight level was increased insignificantly apelin compared with the control. Defining the role of apelin in the body – carries the catabolism of cartilage – this indicator can be used for diagnostic purposes.

Май тіндері адипокиндерінің - апелиннің мәні мен рөлі зерделенді – деформацияланған остеоартрозбен (ДОА) 49 науқаста және оның семіздікпен бірігуі кезіндегі (барлық тексерлігендердің 32). Семіздікпен және ДОА науқастардағы осы көрсеткіштерлің нақты өсуі анықталды. Апелиннмен және дене салмағы индексі деңгейі арасындағы тура түзету тәуелділігі анықталды (r=0,43), апелинмен және инсулиндікрезистентностілік (r=0,46) және кері – ДОА бойынша анамнездің ұзақтығымен (r=-0,61). ДОА мен науқастарда және қалыпты дене салмағымен апелиннің деңгейі бақылау көрсеткіштерімен салыстырған кезде арту тенденциясы ғана болды.ағзадағы апеллиннің рөлін ескере отырып - шеміршек тінінің катаболизмі- осы көрсеткішті диагностикалық мақсатта пайдалануға болады

Настоящее исследование посвящено анализу эффективности соблюдения мультидисциплинарного принципа ведения пациентов после инсульта в отношении восстановления неврологических функций пациентов, повышения уровня их бытовой адаптации, достижения независимости при выполнении отдельных бытовых навыков, а также нормализации психоэмоцинального состояния. Анализу подвергнуты результаты лечения 1000 пациентов. Степень восстановления неврологических функций определялась с помощью шкал Бартел, Линдмарка и Скандинавской; уровень бытовой адаптации – шкалы самооценки бытовых возможностей повседневной жизни Мертон и Саттон; психоэмоциональное состояние – опросника Бека и шкалы самооценки депрессии Уэйкфилда. Согласно результатам исследования, проведение реабилитации с помощью мультидисциплинарной бригад в достоверной степени способствует как повышению уровня восстановления неврологических функций и социально-бытовой адаптации, так и нормализации психоэмоционального состояния пациентов после инсульта.

Information is the result of processing data from one or more sources, which is then processed to provide value, meaning and benefits. In modern times, the use of technology plays a very important role as a means of information and promotion, especially in the field of websites in delivering information. Technological advances in the field of computers are very helpful in the current decision-making process. One method of decision support systems is profile matching. This method is used to determine the assessment in selecting daily employees to become employees. Profile matching is broadly a process of comparing individual competition in job competition so that the difference in competition (also called gap) can be known, the smaller the gap produced, the greater the weight of the value which means that there is a greater chance for employees to occupy the position. After the calculation using the Profile Matching method, the ranking value that meets the requirements is in the alternative with the name of the worker, namely Bakhtiar with a score of 4.535 and is recommended to become a permanent employee. By applying this method, it is very helpful in determining the selection of casual laborers to become permanent employees.

Центральне співвідношення щелеп – одне з самих суперечливих питань в стоматології. Навіть визначень цього терміну у фаховій літературі налічується декілька десятків. Також відомо про чималу кількість способів та методик його фіксації, кожен з яких має свої особливості, переваги і недоліки. В той же час, пошук та реєстрація позиції нижньої щелепи, яку можна було б використовувати в якості відправної при ортопедичному чи ортодонтичному лікуванні є чи не найактуальнішою проблемою. Мета даного дослідження. Проаналізувати точність фіксації центрального співвідношення шелеп найбільш відомими клінічними способами. Матеріали та методи. До дослідної групи ввійшли 10 пацієнтів віком від 25 до 65 років порівно чоловіків та жінок, яким проводилася діагностика в рамках якої робилася цифрова кондилографія. Розподіл пацієнтів за співвідношенням зубних рядів по класифікації Енгля був наступним: 3 пацієнти мали 1-ий клас, 1 2-ий клас 1-ий підклас, 4 2-ий клас 2 підклас та 2 належали до 3-го класу. Моделі верхньої щелепи гіпсувалися до артикулятору Gamma Reference SL за допомогою кондилографу та кінематичної лицевої дуги у істинній шарнірній осі суглобів. В якості контролю використовували реєстрацію центрального співвідношення за даними електронної кондилографії. Висновки. У всіх досліджуваних пацієнтів було виявлене зміщення щелепи під впливом оклюзії від стану центрального співвідношення, причому дельта може коливатися індивідуально і перевищувати 1 мм. Точність реєстрації центрального співвідношення залежить від обраної методики, а також від типу співвідношення щелеп пацієнта. Немає універсального способу реєстрації центрального співвідношення, його вибір мусить базуватись на конкретній клінічній ситуації і індивідуальних особливостях кожного пацієнта. Отримані дані можуть бути корисними для вибору оптимального способу реєстрації центрального співвідношення щелеп в конкретних клінічних умовах.
УЧАСТЬ БАКТЕРІАЛЬНИХ ПРЕПАРАТІВ В КОМПЛЕКСНОМУ ЛІКУВАННІ КАНДИДОЗНОГО УРАЖЕННЯ СЛИЗОВОЇ ОБОЛОНКИ РОТОВОЇ ПОРОЖНИНИ (ОГЛЯД ЛІТЕРАТУРИ)

Резюме. В огляді літературних джерел представлені дані щодо сучасних поглядів на використання бактеріальних препаратів (пробіотики, пребіотики та синбіотики) при лікуванні грибкової інфекції ротової порожнини. Метою цього огляду було зібрати різні дослідження, зосереджені на механізмі дії пробіотичних штамів на Candida sp. та обговорити їх вплив на профілактику загострень та рецидиву кандидозу. Пробіотики застосовують при різних захворюваннях, що супроводжуються порушенням балансу в біотопах організму. Сучасні про біотичні препарати володіють кислото- та антибіотикостійкістю, підходять для використання в різних вікових групах при захворюваннях, які спричиняються мікотичною інфекцією. Як представники нормальної мікрофлори, пробіотичні штами (Lactobacillus spр., Bifidobacterium spр.) впливають на такі функції, як підтримка колонізаційної резистентності, продукція метаболітів для макроорганізму, регуляція місцевої та адаптивної імунної відповіді. Серед властивостей пробіотиків є протигрибкова дія за рахунок сумісної агрегації, зміни рН ротової порожнини з утворенням молочної кислоти та інших органічних кислот, які інгібірують вірулентність клітин Candida та продукцію Н2О2, що дає змогу їх використання при кандидозному ураженні СО. Результатами дослідження встановлено, що кишкова паличка Escherichia coli (штам MG1655) знищує Candida albicans (штам SC5314) in vitro. Було виявлено, що Escherichia coli продукує розчинний фактор, який вбиває Candida albicans, дія якого, у свою чергу, є залежною від концентрації магнію в крові Висновки. Отримані результати обґрунтовують доцільність подальшого вивчення протигрибкової активності бактеріальних препаратів у хворих з інфекцією ротової порожнини, обумовленою грибами роду Candida. Подальше вивчення їх властивостей дозволить розширити діапазон використання пробіотиків.
