Authors: Xiao Shan , Wang Xiao Bei , Yang Ye , Wang Qin
Published: June 2024

Type 2 diabetes mellitus combined with metabolic dysfunction-associated steatotic liver disease (MASLD) leads to an increasing incidence of liver injury year by year, and patients are at a significantly higher risk of developing cirrhosis or even liver failure. No drugs have emerged to specifically treat this disease. The aim of this study is to investigate the mechanisms and causative hub genes of type 2 diabetes combined with MASLD. The data were obtained through the GEO platform for bioinformatics analysis and validated by in vitro experiments to find the causative targets of type 2 diabetes mellitus combined with MASLD, which will provide some theoretical basis for the development of future therapeutic drugs. GSE23343 and GSE49541 were downloaded from the Gene Expression Omnibus (GEO) database to identify differentially expressed genes (DEGs) in type 2 diabetes mellitus combined with MASLD for functional enrichment analysis. And STRING database and Cytoscape software were used to construct Protein–Protein Interaction (PPI) and hub gene networks. And GO (gene ontology, GO) analysis and KEGG (Kyoto encyclopedia of genes and genomes, KEGG) enrichment analysis were performed on target genes. A total of 185 co-expressed DEGs were obtained by differential analysis, and 20 key genes involved in the development and progression of type 2 diabetes were finally screened. These 20 key genes were involved in 529 GO enrichment results and 20 KEGG enrichment results, and were mainly associated with ECM–receptor interaction, Focal adhesion, Human papillomavirus infection, PI3K-Akt signaling pathway, and the Toll-like receptor signaling pathway. A total of two target genes (SPP1, collagen IV) were found to be highly correlated with type 2 diabetes mellitus combined with MASLD. Real time PCR results showed that there was a significant difference in SPP1 and collagen IV mRNA expression among the three groups (P < 0.05). SPP1 and Collagen IV may be candidate biomarkers for type 2 diabetes mellitus combined with MASLD, as verified by bioinformatics screening and in vitro experiments. Our findings provide new targets for the treatment of type 2 diabetes combined with MASLD.
Layered complexity, reorganisational ability and self-healing mechanisms of heteropolysaccharide solutions
Authors: Ivashchenko Olena
Published: June 2024

Heteropolysaccharides are among the most widely distributed compounds in nature, acting as both tissue building blocks and as a source of nutrients. Their physicochemical and biological properties have been studied thoroughly; however, the microstructural properties of heteropolysaccharides are still poorly understood. This study aims to investigate the micro-structural peculiarities of agarose, gum arabic, hyaluronic and alginic acids by means of confocal laser scanning microscopy (CLSM) and cryogenic scanning electron microscopy (cryo-SEM). Herein, attention is paid to layered complexity of the microstructure differentiating surface, under surface, inner, and substrate interface layers. The scale and pattern of the polysaccharide’s microstructure depend on the concentration, changing from lamellae to cell-like porous structures. This work provides the insight into micro- and nanoscale mechanisms of self-healing and substrate-induced reorganisation. Thus, investigation of the self-healing mechanism revealed that this diffusion-based process starts from the fibres, turning into lamellae, following by cell-like structures with smaller dimensions. Investigation of the substrate-induced reorganisation ability showed that nano-to-micro (scale) porous substrate causes reorganisation in the interface layer of the studied heteropolysaccharides. This work contributes to understanding the structural peculiarities of heteropolysaccharides by looking at them through a supramolecular, micro-level prism.
Quantitative analysis of commercial coating penetration into Fagus crenata wood using X-ray microtomography
Authors: Ekaputri Tyana Solichah , Tanaka Takashi
Published: June 2024

Recent advances in wood treatment include the use of eco-friendly coatings to improve the wood’s dimensional stability and appearance. Assessing coating performance during its service life is critical for establishing a knowledge base for product optimization. Numerous approaches, including microimaging, are available for analyzing coating behavior. In addition to conventional microscopic techniques, high-resolution X-ray microtomography is a tool that provides nondestructive imaging of coatings and their substrates. In this study, we performed two-dimensional (2D) and three-dimensional (3D) visualization of tomographic reconstruction images of two coating types, spray and brush, to observe and assess the distribution of several commercial Japanese coating materials inFagus crenata. X-ray images and plot profiles were used to determine the penetration depths and thicknesses of coatings. Each coated sample was scanned using X-ray microtomography, which allowed successful visualization and quantification of the coating penetration depth. Chemical content and concentration of the coating materials influenced penetration depth and amount.
Unique attributes of official endorsers in destination marketing
Authors: Zhao Yipeng , Li Yan , Liu Bo , Chang Haodong , Guo Yining
Published: June 2024

Along with the digital transformation of the administrative environment and the end of the COVID-19 pandemic, official endorsers have nurtured a new channel for tourism destination marketing, which is of great significance to local economic recovery. However, less attention has been paid to the different effects of endorsement between ordinary endorsers and official endorsers, mainly due to their contrasting social statuses. To bridge the research gap, the source credibility model and social identity theory are integrated to construct the distinctive attributes of officials, as well as structural equation model is utilized to explore the underlying mechanism of official endorsement. Findings indicate that trustworthiness, the sense of authority, expertise, and attractiveness have direct positive effects on official identification, while also indirectly influencing tourists’ attitudes toward the destination through official identification. These findings provide theoretical and managerial implications for the local government managers involved in tourism destination marketing.
High pulse wave velocity is associated with enlarged perivascular spaces in dementia with Lewy bodies
Authors: Saji Naoki , Kinjo Yoshino , Murotani Kenta , Niida Shumpei , Takeda Akinori , Sakurai Takashi
Published: June 2024

Previous studies have demonstrated associations between enlarged perivascular spaces (EPVS) and dementias such as Alzheimer’s disease. However, an association between EPVS and dementia with Lewy bodies (DLB) has not yet been clarified. We performed a cross-sectional analysis of our prospective study cohort of 109 participants (16 with DLB). We assessed cognitive function, pulse wave velocity (PWV), and brain magnetic resonance imaging features. The relationships between EPVS and DLB were evaluated using multivariable logistic regression analyses. Compared with the non-dementia group, the DLB group was more likely to have EPVS in the basal ganglia. Compared with participants without EPVS, those with EPVS were older and had cognitive impairment and high PWV. In multivariable analyses, EPVS in the basal ganglia was independently associated with DLB. High PWV was also independently associated with EPVS in both the basal ganglia and centrum semiovale. High PWV may cause cerebrovascular pulsatility, leading to accelerated EPVS in DLB participants.
Seasonal dependence of deterministic versus stochastic processes influencing soil fungal community composition in a lowland Amazonian rain forest
Authors: Buscardo Erika , Geml József , Nagy Laszlo
Published: June 2024

The contribution of deterministic versus stochastic processes to the spatio-temporal assembly of soil microbial communities in tropical forests requires quantification so that responses to climate change may be accurately projected. Here we report the spatio-temporal composition of soil fungal communities in a topographically homogeneous forest area in central Amazonia. Soil fungal communities have a greater turnover in space than over time. Stochastic processes are inferred to dominate in the rainy season and deterministic processes in the dry season. Our study highlights the importance of spatial heterogeneity in the absence of environmental gradients and its relationship with seasonal patterns that modulate spatial heterogeneity and contribute to environmental determinism versus stochasticity for fungal community assembly. This baseline may serve to assess deviations in community patterns caused by changes in biotic interactions with above-ground vegetation, such as those resulting from shifts in taxonomical/functional composition of trees driven by climate change.

Published: June 2024

To complement donor-dependent platelets supplies, we previously developed an ex vivo manufacturing system using induced pluripotent stem cell (iPSC)-derived expandable immortalized megakaryocyte progenitor cell lines (imMKCLs), and a turbulent flow bioreactor to generate iPSC-derived platelets products (iPSC-PLTs). However, the tank size of the bioreactor was limited to 10 L. Here we examined the feasibility of scaling up to 50 L with reciprocal motion by two impellers. Under optimized turbulence parameters corresponding to 10 L bioreactor, 50 L bioreactor elicited iPSC-PLTs with intact in vivo hemostatic function but with less production efficiency. This insufficiency was caused by increased defective turbulent flow space. A computer simulation proposed that designing 50 L turbulent flow bioreactor with three impellers or a new bioreactor with a modified rotating impeller and unique structure reduces this space. These findings indicate that large-scale iPSC-PLTs manufacturing from cultured imMKCLs requires optimization of the tank structure in addition to optimal turbulent energy and shear stress.
Limitations of current techniques in clinical antimicrobial resistance diagnosis: examples and future prospects
Authors: Hassall Jack , Coxon Carmen , Patel Vishal C. , Goldenberg Simon D. , Sergaki Chrysi
Published: June 2024

Antimicrobial resistance is a global threat to public health. Without proactive intervention, common infections may become untreatable, restricting the types of clinical intervention that can be undertaken and reversing improvements in mortality rates. Effective antimicrobial stewardship represents one approach to restrict the spread of antimicrobial resistance but relies on rapid and accurate diagnostics that minimise the unnecessary use of antibiotics. This is increasingly a key unmet clinical need. In this paper, we describe existing techniques for the detection of antimicrobial resistance, while examining their drawbacks and limitations. We also discuss emerging diagnostic technologies in the field, and the need for standardisation to allow for swifter and more widespread clinical adoption.

Authors: Apsemetov Muktar , Chymyrov Akylbek , Kurmanbek uulu Nurlan , Attokurov Bekbolot
Published: June 2024

The work has developed measures to reduce the risk of a landslide in the area near the village of Toktogul, Uzgen district of the Kyrgyz Republic. This landslide area was studied on the basis of field research on the ground and the results of desk work. The sliding of soil masses in the area can cause destruction and debris of residential and administrative buildings, roads and power lines, as well as injury and death. Considering the equilibrium of the system of forces acting on the mass of filler soil of the slope section and analyzing them, measures for unloading the landslide body in this section are proposed. The proposed longitudinal profiles of drainage channels to reduce the moisture content of subsidence soil and transverse profiles of developed soil to reduce the weight of subsidence soil are presented. Based on the results of processing research data and analysis, it is recommended to reduce the weight of unstable (subsidence) soil by stepwise development along the slope of the site and transporting it up to 5 km for subsequent brick production. It is also recommended to protect subsidence soil from waterlogging by installing drainage channels. Based on the results of the research, a real project was developed to protect the site from landslides near the village of Toktogul. The proposed measures make it possible to reduce the risk of a landslide in the area under consideration using methods and technical means that are inexpensive and accessible to government agencies and local administrations.

Authors: Nazarenko Olesya
Published: June 2024

The work is devoted to analysing the transformation of humidification in a changing climate in the eastern part of Cuba, the case of Holguin (east of the island). The importance of the study is related to the need to study precipitation trends in certain regions. Based on the analysis of the long-term dynamics of annual precipitation values, relative humidity, and the number of days with precipitation, trends in the degree of moisture in the east of the island was established. The practical significance of the work lies in identifying and developing long-term weather forecasts and planning the economic and recreational development of the territory. The 1970–2020 period was considered. Changes in the amount of precipitation and days with precipitation were analysed. The moisture coefficient for the territory was calculated. The wettest and driest periods were identified, with the wettest being from 1981 to 1985 and the driest being from 1991 to 1995. The average rainfall for the wettest period was 1365 mm, while the average rainfall for the driest period was 335 mm. There was an increase in the number of days with precipitation from 39 days (1970) to 150 (2007). The maximum values of days with precipitation occurred in the period from 2006 to 2010. The calculated balance of humidification of the territory revealed heterogeneity of conditions of humidification of the territory. The maximum moisture deficit falls in the period from February to April, and the minimum – in June. The annual moisture balance was -653 mm. The territory is experiencing a lack of moisture.
Stray bird species are reference points of the initial stages of changing areas in conditions of directional climate change (on The example Eastern Siberia)
Authors: Mel’nikov Yuriy
Published: June 2024

We have shown that Eastern Siberia has now become the scene of climate change, which is determined by its location – the center of Inner Asia. It was found that as a result of increased solar activity on the western edge of Eurasia, the latitudinal transfer of air masses was replaced by a meridional (North Atlantic sector) one. Later, such a shift was observed in the eastern (Pacific) sector of Asia. As a result, a hotbed of elevated surface air temperature was formed in Eastern Siberia and adjacent areas of Mongolia and China, and distant bird evictions to the north, east and west were observed. It is shown that such flights are the first stage of the transformation of bird areas. In the first half of the 20th century, weak western and eastern bird streams have already reached of the hollow Lake Baikal. By the middle of the 20th century, 60 new bird species had been recorded here, but their numbers were insignificant. Subsequently, there were clear trends among them towards further expansion of their areas.

Studying the parameters of a ridge-forming roller for soil preparation is an urgent task in agricultural technology. This paper examines the influence of various parameters of ridge-forming rollers on the quality of soil tillage and its preparation for sowing. The main parameters are analyzed, such as the shape of the rollers, the depth of cultivation, the angle of inclination of the ridges, as well as the influence of their combinations on the structure of the soil and its air-water regime. The effectiveness of various configurations of ridge-forming rollers is assessed in order to optimize the process of preparing the soil for further agrotechnical measures. The results obtained can be used to develop recommendations for the selection of optimal parameters of ridge-forming rollers depending on the specific conditions of the soil and climatic region.

The article presents the results of studies conducted to evaluate the effectiveness of BioEcoss fertilizers in various concentrations in hot vegetable pepper cultivation. The experiment was conducted in 2022/2023 in a glazed winter greenhouse, geographically located in the Kuban State Agrarian University Botanical Garden, Krasnodar. The object of research is the variety of hot vegetable pepper “Pikovaya Dama” (“Queen of Spades”). It was found that the introduction of the studied organomineral fertilizer in any studied concentration (from 1% to 3%) accelerated the plants flowering onset and fruits biological ripeness compared with the control, increased productivity and average fruit weight. The highest fertilizer concentration in the experiment (3%) contributed to earlier fruit harvest dates (earlier than the control for 18 days), fruiting period extension, increase in fruits number on branches of the first and second order to 10 pieces (at the control – 7), fruits average weight increase. The yield in this variant of the experiment was 0.66 kg / m2, which was higher than the control by 0.42 kg / m2, other variants with the addition of a less concentrated solution – by 1.4-2.1 times. The use of fertilizers in any concentration contributed to 100% marketability of fruits.

It is noted in the work that the increase in the efficiency of agricultural production in our time is not possible without reducing energy costs. At the same time, the technical means of mechanization of the tillage process have a high material consumption, which leads to an increase in energy consumption, indicating energy and environmental problems. In an effort to improve the quality of soil preparation, expand the functionality of the unit, reduce energy consumption, simplify design and import substitution, the use of known tillage tools has been studied and analyzed. As a result, on the basis of exploratory research, a modernized tillage unit has been developed. The new elements of which are that a chopper module is mounted behind the disk module, consisting of staggered chopper rollers in two rows. The modernized tillage unit considered in the article, developed on the basis of KubGAU, improves the quality indicators of soil cultivation, on which the effective accumulation and consumption of soil moisture depends, reduces energy consumption by increasing the functionality of the unit.

The purpose of this work was to study the effect of air temperature on the duration of the growing season in Western Siberia (Russia). Material and methods: phenological observation of 6 varieties of spring barley (Abalak, Zolotnik Naran, Tandem, DLA-14 and Pasadena) was carried out for the period from 2016 to 2020. The sensitivity of varieties to temperature conditions is determined. The optimal average daily air temperature during the interphase periods was established: shoots-heading 31-35 days, and heading-ripeness 34-37 days. The optimal sums of effective temperatures above 10 ºC, necessary for the growth, and development of spring barley varieties, have been calculated. The Abalak variety was distinguished by a narrow temperature range in both interphase periods (the first period - 0.7 ºC; the second - 2.3 ºC), which indicates a low plasticity of this variety. The agrometeorological characteristic obtained from the data of field experiments can be used to identify the areas of cultivation of varieties, as well as for a scientifically based assessment of the territory in relation to the variety. The optimal, minimum air temperatures for each variety are calculated. The sensitivity of varieties to temperature changes was studied.
New approaches to edge passivation of laser cut PERC solar cells

Published: June 2024

Recently the development trend in the PV industry is towards much larger wafer formats. With increasing wafer area and the resulting increase in short-circuit current at the cell level, there is also a trend towards sub-cells (solar cell cut into smaller pieces) for module integration. Using sub-cells, the resistance losses through the connection can be reduced. Modules based on sub-cells achieve higher levels of fill factors and thus a higher nominal power. However, the energy yield of such sub-cells is reduced compared to full cells due to the non-passivated laser edge. The laser cut edge causes a high recombination of the charge carriers, which negatively affects the pseudo fill factor as well as open-circuit voltage of the cell. The current work introduces two different approaches for passivating the laser separated PERC solar cells. The experiments were performed on p-type PERC monofacial cells and laser scribe and mechanical cleavage (LSMC) technique was used to obtain sub-cells from the host cells. The method ‘laser scribing and simultaneous Al doping’ increases the pFF of the cleaved cells by +0.2–0.4%abs in comparison to the reference cleaved cells whereas the method ‘laser scribing and subsequent Al doping’ shows an improvement in efficiency of the cleaved cells by + 0.2% abs.

Published: June 2024

Die Diagnose einer lebensbedrohlichen Erkrankung kann zu einer Reaktualisierung
existenzieller Konflikte führen. Der plötzliche Verlust von Kontinuität,
körperlicher Integrität, und sozialen Rollen kann die psychischen
Verarbeitungsmöglichkeiten der Patient:innen überfordern. Insbesondere affektive
Störungen und Symptome existenzieller Belastung erschweren die psychosoziale und
medizinische Versorgung. Psychodynamische Behandlungsansätze können das Erleben
von Nähe und Verbundenheit zu stärken, um Verluste zu bewältigen und
Abschiedsprozesse zu ermöglichen. Das ORPHYS Manual beschreibt eine
psychodynamische Kurzzeitpsychotherapie (12–24 Sitzungen), die das Ziel hat,
existenzielle Belastungen schwer körperlich Erkrankter vor dem Hintergrund
interaktioneller Konflikte am Lebensende zu adressieren. Die Kombination
stützender und konfliktaufdeckender Interventionen, die nah am subjektiven
Erleben und der individuellen Krankheitssituation der Patient:innen formuliert
werden, soll diesen dabei helfen, abgewehrte affektive Zustände zu integrieren
sowie einen Zugang zu eigenen Beziehungs- und Bewältigungsmustern zu erlangen.
ORPHYS soll einen gemeinsamen Trauerprozess ermöglichen, bei dem der intensive
Wunsch nach Beziehung am Lebensende und die Realität des Sterbens
nebeneinanderstehen können.
