Authors: Zart Laudemir Luiz , Souza Maria José Dantas
Published: February 2025

Formação e Organização: experiência em economia solidária e cooperativismo é uma reflexão sobre o envolvimento de grupos constituídos de sujeitos que se dispõem a vivenciar uma experiência coletiva, em um espaço comum de comercialização em um empreendimento econômico solidário. Esses sujeitos têm como referência o cenário onde se originaram as lutas sociais, que serve de base para a estruturação do cooperativismo e para o movimento da economia solidária. Nesse sentido, tomamos o lócus e os sujeitos em suas dimensões territorial, histórico-social e política, na busca por responder se, e de que modo, o envolvimento dos produtores/consumidores na Cooperativa de Consumo Solidário e Sustentável (Cooperssol) se constituiu em prática pedagógica capaz de promover mudanças das práticas sociais para a constituição da cultura da solidariedade?

Published: February 2025

Background: Pediatric olecranon fractures, which involve a break in the bony prominence of the elbow, are relatively rare but can be serious. Treatment options typically depend on the type and severity of the fracture. Displaced, intraarticular fractures require surgical intervention, where resorbable implants are becoming a promising alternative to traditional metal hardware. Methods: Our prospective, single-center, single-arm case series evaluates three pediatric olecranon fracture patients treated by resorbable poly-L-lactic-co-glycolic acid (PLGA) pins and polydioxanone (PDS) loops between Jan 2022 and January 2023 at the Department of Pediatrics, University of Pécs, Clinical Complex. Results: All patients achieved complete radiological healing with excellent functional recovery and no implant-related complications at one-year follow-up. Conclusion: Resorbable PLGA pins and PDS loops provide a promising alternative to conventional metallic fixation in pediatric olecranon fractures, abolishing the need for a second implant removal surgery while maintaining stability and biocompatibility. Our findings support the child-friendly nature and growing role of biodegradable materials in pediatric fracture management.

Published: February 2025

Background
Effective communication is crucial during pandemics to mitigate fear and promote acceptance of public health measures. However, the COVID-19 pandemic revealed significant challenges, including an overwhelming volume of scientific information, poor quality control, and a rise in false or misleading data. Peer-reviewed publications often faced criticism for fast-tracked review processes, with pre-prints contributing to an increased retraction rate. These issues undermined public trust and the implementation of evidence-based measures.
Methods
The Horizon2020 ORCHESTRA project developed the COVID-19 Global Guidance Group (CGGG), an external expert evaluation mechanism, to critically assess scientific publications and ensure the dissemination of accurate and relevant findings. The CGGG employed the Delphi method to systematically achieve expert consensus on the evaluation of research outputs. Findings were tailored for stakeholders such as policymakers, the scientific community, and the general public.
Results
The CGGG evaluated over 100 peer-reviewed publications, achieving an average impact factor of 8.7 and ensuring the dissemination of evidence-based findings. The use of the Delphi method enhanced the rigor of the evaluation process and improved the targeting of communication strategies, addressing gaps in public and scientific engagement during the pandemic.
Conclusions
The ORCHESTRA project’s experience highlights the value of external expert evaluation, supported by consensus-building approaches like the Delphi method, in scientific dissemination during crises. Broader adoption of similar mechanisms could improve the integrity and effectiveness of communication strategies, bolstering public trust and evidence-based policymaking in future health emergencies.
The relationship of cytomegalovirus with physical functioning and health-related quality of life in older adults
Authors: Kirkham Frances A , Shwe Phu Sabei , Mensah Ekow , Rajkumar C
Published: February 2025

Methods
210 participants in the south of England with mean age 69.8 years underwent demographic and medical questionnaires, measures of body composition (bioimpedance analysis), handgrip strength and the short form 36 item survey of quality of life (SF36). All participants had peripheral venepuncture to assess CMV serology and inflammatory markers. Measures of sarcopenia were calculated using European Working Group definitions.
Results
51.7% of participants were positive for CMV IgG. There were no significant differences between CMV positive and negative groups in age, gender, measures of sarcopenia or inflammatory markers. CMV positive groups had lower scores in all domains of the SF36, with significantly lower physical function score (88.7 vs 81.3, p = 0.003) as well as total score, limitations due to physical health, energy/fatigue, social functioning and pain. Physical functioning score was significantly correlated with measures of sarcopenia including handgrip strength (r = 0.155 p = 0.026) and appendicular skeletal muscle mass index (r = 0.201, p = 0.005). On linear regression, CMV status was significantly associated with SF36 physical function score (p = 0.004) after adjustment for age, gender, BMI, CRP and handgrip strength.
Conclusion
CMV positivity is significantly associated with physical function and health-related quality of life in older adults, although its direct relationship to sarcopenia is yet to be fully ascertained.

Flexible photoelectric power sources are promising to power Internet-of-things sensors, freeing the limitations of wired power sources or batteries and enabling bio-integrated devices. Traditional photo power sources have to be integrated with energy storage modules since photovoltaic materials have an order of nanosecond lifetime for photogenerated charge carriers. Obtaining flexible, biocompatible power sources that can perform light harvesting and store energy simultaneously is still challenging. In this paper, inspired by natural ion gradient diffusion in organisms, we develop a novel photoelectric conversion mechanism that synchronizes the mechanism of photoinduced ion gradient diffusion and photo-REDOX pairs (I-PR), offering an ion-hydrogel-based flexible photo power source. Through the photochemical process of ammonium molybdate, the electric potential of the device is regulated by the altered ion gradient of gelatin hydrogel and the REDOX (/) pairs, to generate energy. In comparison with photovoltaic materials-based photo power sources, the carrier life is times longer than that of commercial solar cell, we can still obtain a considerable output power for milliseconds to thousands of seconds after the termination of the initial illumination. Additionally, reaping the benefits from I-PR, the open-circuit potential is independent of the power sources’ volume. The flexible hydrogel droplets support the fabrication of arbitrary and millimetre-scale structures. A single photo power source can generate an open-circuit potential of ~ 250 mV, even with a 20-fold reduction in volume to ~10 mm3. The reversible hydrogel network allows for the recovery and re-manufacturing of the photo power source, with a 61% potential retention rate after two cycles of recycling and re-manufacturing. We further demonstrate the flexible photo power source can stimulate the activity of biological tissue cells, regulate the expression of proliferative genes on demand and facilitate tissue wound repair. This ionic hydrogel opens a new avenue for flexible, battery-free, biocompatible devices.
Metabolomic Signatures in Adults with Metabolic Syndrome Indicate Preclinical Disruptions in Pathways Associated with High-Density Lipoprotein Cholesterol, Sugar Alcohols
Authors: Lewis K. A. , Stroebel Benjamin M. , Kanaya Alka M. , Aouizerat Bradley , Longoria Kayla D. , Flowers Elena
Published: February 2025

Background
Metabolic syndrome is a pressing public health issue and risk factor for the development of type 2 diabetes (T2D) and cardiovascular disease (CVD), yet clinical practice is lacking in biomarkers that represent pre-clinical perturbations of the heterogenous subtypes of risk. This study aimed to characterize the baseline metabolome in relation to known clinical characteristics of risk in a sample of obese adults.
Methods
Untargeted metabolome data from N = 126 plasma samples with baseline data from a previously completed study including obese adults with metabolic syndrome. Metabolites were acquired using validated liquid chromatography mass spectrometry methods with 15–25 internal standards quantified by peak heights. Pearson’s correlations were used to determine relationships between baseline metabolites, sample characteristics (e.g., age, body mass index (BMI)), and atherosclerotic clinical characteristics (e.g., high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), triglycerides), adjusting for multiple comparisons using the Benjamini-Hochberg False Discovery Rate (FDR) method. Differences in metabolite levels between clinical classifications of dysglycemia (e.g., normal, prediabetes, diabetes) at baseline were assessed using ANOVA and adjusted for multiple comparisons and adjusted for covariates.
Results
The sample consisted primarily of female (74%) participants, predominantly white (70%), with an average age of 56 years. After FDR adjustment, two baseline metabolites were significantly associated with age (xylose, threitol), two with BMI (shikimic acid, propane-1,3-diol), one with LDL (tocopherol-alpha), and 42 with HDL cholesterol. Three metabolites were significantly associated with fasting blood glucose (FBG) levels at baseline (glucose, gluconic acid lactone, pelargonic acid).
Conclusions
This study identified novel metabolite associations with known markers of T2D and CVD risk. Specific metabolites, such as alpha-tocopherol, branched-chain amino acids (BCAAs), and sugar-derived metabolites like mannose and xylose, were significantly associated with age, BMI, lipid profiles, and glucose measures. Although most sample participants had normal HDL cholesterol at baseline, 42 metabolites including branched chain amino acids were significantly associated with HDL, suggesting pre-clinical perturbations in biological pathways associated with both diabetes and cardiovascular comorbidities. Metabolomic signatures specific to prediabetes and metabolic syndrome can enhance risk stratification and enable targeted prevention strategies for T2D. Longitudinal studies are needed to understand how these associations change over time in at-risk individuals compared with controls.

Background: Urban malaria transmission in sub-Saharan Africa is often underestimated, emphasizing the need for research on vector distribution, abundance, behavior, and infectivity in cities. Since 2003, urban malaria transmission has intensified. Monitoring Anophelespopulations is crucial for developing effective interventions. This study examined the biting and resting habits, distribution, abundance, and Plasmodiuminfection of malaria vectors in Accra.
Methods: Adult malaria vectors were collected using human landing catch (HLC) and Prokopack aspiration (PPK) at ten sites in Accra, categorized into five groups: sites with Irrigated Urban Farming (IUF), Lower Socioeconomic Status (LS), Middle Socioeconomic Status (MS), High Socioeconomic Status (HS), and Peri-urban (PU) areas. Biting patterns and entomological transmission indices of An. gambiae s.l. were assessed, Molecular methods were used to detect sporozoite infection, bloodmeal sources, vector species, and insecticide resistant mutation genes.
Results: A total of 41,747 mosquitoes were collected. Of these, 95.49% (39,863/41,747) were host-seeking collected through human landing catch (HLC), consisting of Anopheles (52.54%, 20,945/39,863), Culex(42.00%, 16,742/39,863), Aedes (3.74%, 1,491/39,863), and Mansonia (1.72%, 685/39,863). The remaining 4.51% (1,884/41,747) were resting mosquitoes collected using a Procopack aspirator, comprising Anopheles (31.26%, 589), Culex (57.21%, 1,078), and Aedes (11.52%, 217). Overall, the irrigated urban farming (IUF) site category recorded the highest abundance of An. gambiae s.l. (48.63%, 10,466/21,520), followed by the peri-urban (PU) site category (18.06%, 3,887/21,520), high socioeconomic (HS) site category (16.42%, 3,533/21,520), middle socioeconomic (MS) site category (13.74%, 2,956/21,520), and low socioeconomic (LS) site category (3.15%, 678/21,520) in both HLC and Procopack collections.
Significantly higher mosquito biting activity was observed during the late evening (LE), the classical mosquito biting time, in both the rainy (71.45%, 11,337/15,865) and dry (72.21%, 3,658/5,066) seasons. Indoor An. gambiae s.l. had higher sporozoite infectivity (70.64%, 77/109) than outdoor mosquitoes (29.35%, 32/109) (χ² = 6.78, P = 0.009). Tuba from the IUF site had the highest sporozoite infectivity (32.11%, 35/109), with higher indoor (24.77%, 27/109) than outdoor (7.34%, 8/109) rates.
Conclusion: Anopheles gambiae s.l. drives urban malaria transmission in Accra, with high human bloodmeal indices and sporozoite infectivity, especially indoors. Urban agriculture promotes vector proliferation. Targeted indoor control and management of breeding sites in IUF areas are essential to reduce transmission.

Published: February 2025

Aim: In this study, we sought to investigate the success of nucleated red blood cells (NRBCs ) in predicting disease severity and mortality in patients with AP.
Methods: This single-center, retrospective study was conducted in AP patients admitted to the emergency department. NRBCs values and other laboratory data were recorded in the study form. Patients were divided into three groups according to disease severity (mild, moderate and severe) and two groups according to outcome (survivors and non-survivors). Results: Half of the 296 patients included in the study were male and the mean age was 55.6±17.9 years. NRBCs values were higher in severe cases than in mild and moderate groups. In the Receiver operating characteristic (ROC) analysis performed to determine disease severity, the specificity, sensitivity and area under curve (AUC) values for NRBCs were 58,8%, 91.8%, and 0.755, respectively. The NRBCs values were higher in non-survivors patients than in survivors patients. In the ROC analysis performed to detect non-survivors patients, the specificity sensitivity and AUC values for NRBCs were 63,6%, 90,9% and 0.770, respectively.
Conclusion: In AP patients, high NRBCs levels may be successful in predicting both disease severity and mortality. However, more studies are needed for clinical use
Monitoring of Biodiversity in the Erbil Governorate -Iraq Using Remote Sensing Data
Authors: Shwan Othman Hussein  , Daban Kadhim Omar  , Karzan Ahmed Abdulwahid
Published: February 2025

Ensuring the health and diversity of ecosystems has always been a challenge for conservationists. It takes years of direct work in the field for ecologists to gather sufficient data to reliably portray the conditions of an ecosystem. In many instances, their work produces an invaluable picture of the conditions as they are and, more importantly, the conditions that are changing over time. Yet, traditional methods of monitoring biodiversity simply cannot keep up with the demands of today's conservation imperative. They are labor-intensive, fail to produce timely results, and are in large part inaccessible to those who might use the information they produce. In much the same way, the potential of remote sensing to meet those demands remains largely untapped. This study utilizes remote sensing data to monitor biodiversity changes in the Erbil Governorate, Iraq, focusing on the Enhanced Vegetation Index (EVI), Standardized Precipitation Index (SPI), and Net Primary Productivity (NPP) as proxies for biodiversity change. To do this, it combines data from MODIS and Sentinel-2 satellites with meteorological information to evaluate the spatial and temporal changes in vegetation that occurred during the recent recorded drought. The most dramatic improvement observed in the three key variables was with the EVI, which increased almost straight up from below EVI value of 2 in 2017 to almost 3 in 2020, as seen in the plot above, with the EVI gradient increasing around 2019.
In 2017, the median NPP values hovered approximately around 0.15 kgC/m²; however, they had clearly risen to nearly 0.25 kgC/m² by 2020. What's more, this research demonstrated a strong positive correlation between the EVI, derived from Sentinel-2 data, and NPP computed from MODIS. The correlation coefficients for these areas ranged from 0.68 to 0.74.
These results reaffirm the potent capabilities of satellite remote sensing for studying ecosystem dynamics and offer an unprecedented glimpse into the sophisticated ecological interplay of this understudied area. Biologists don't even fully understand the basic organ-level functions of this system, so knowing how a system as complex as this one work and understanding its dynamics are crucial for effective conservation and management of its constituent ecosystems.
Climate Agreement. Race to Carbon Neutrality From Rio Via Kyoto and Paris to Glasgow
Authors: PAVLIUK Nonna
Published: February 2025

This paper demonstrates an influence of the anthropogenic Carbon Dioxide (CO2) emission trend on climate talks aimed to reduce greenhouse gas emissions. The influence of commitments to reduce greenhouse gas emissions, undertaken by the largest emitter countries within the framework of international treaties (the Kyoto Protocol and the Paris Agreement), on the fossil energy consumption and CO2 emissions from the combustion of various types of fuel by these countries has been analyzed. Emissions from the European Union (EU), as well as consumption of renewable and alternative energy sources by countries are beyond the subject of this paper.

The paper focuses on the obligations that the largest emitters of greenhouse gas emissions are ready to undertake in order to achieve carbon neutrality by 2050. The impact of the country’s choice of the base year on its ambitious climate action to reduce emissions has been evaluated. Challenges that the countries may face in the implementation of the Net Zero by 2050: A Roadmap for the Global Energy Sector, developed by the International Energy Agency (IEA), have been identified.

Authors: WYCZARSKA-KOKOT Joanna
Published: February 2025

Contemporary requirements on the quality of swimming pool water necessitate the improvement of the classical technology of its treatment. It is associated with the need to modernize installations or implement a new technology. The purpose of the analysis is to compare the effects of using classical and modified technologies for the treatment of swimming pool water in sports and recreational pools with similar characteristics. The research was carried out for ten pools, which were divided into two groups – pools with a classical water treatment system and a modified one. The conducted tests showed significant differences in water quality in terms of: pH, redox, permanganate index (CODMn), total organic carbon (TOC), free chlorine, combined chlorine, chloroform and trihalomethanes (THMs), and no differences in terms of: temperature, turbidity, nitrates and ammonium ion. It was found that the modified swimming pool water treatment technologies made it possible to obtain water of better quality with regard to physical, chemical and bacteriological properties.

Published: February 2025

The purpose of this study was to examine the effects of the voluntary disclosure program and the harmonization of tax regulations on increasing the amount of tax payable by taxpayers in Indonesia. In addition, it explored their role in the formation of different levels of budgets through tax revenues. This analysis focused on individual taxpayers registered as active taxpayers, with a final sample of 95 respondents. Multiple regression analysis was employed as the analytical tool. The results show that the voluntary disclosure program did not significantly affect the increase in taxes payable, as it does not always result in additional tax liability or expose taxpayers to penalties, interest, or fines. In contrast, the harmonization of tax regulations significantly influenced the increase in taxes payable. Simplified tax administration and improved compliance, driven by tax regulation changes, led to higher tax payable. The findings imply that adjustments to tax regulations can have a substantial impact on the formation of tax revenue, which is vital for government budgetary allocations at various levels.

EXTRACTION OF BENZYL ISOTHIOCYANATE (BITC) IN CHEMISTRY TEACHING THROUGH THE PROBLEMATIZED EXPERIMENTAL ACTIVITY (PEA): POSSIBILITY OF REUSING PAPAYA SEEDS. This study investigated the reuse of papaya seeds for the extraction of benzyl isothiocyanate (BITC) as a context to foster the construction and deepening of chemical concepts in the initial training of chemistry teachers at the Federal University of Espírito Santo (UFES). Using Problematized Experimental Activity (PEA) as a teaching strategy, students conducted experiments to extract BITC from papaya seeds and applied ultra-violet (UV)-visible spectroscopy for its quantification. The results revealed that the highest BITC concentration was obtained from ethanolic extracts of dried seeds. At the end of the course, students developed teaching projects to incorporate this environmental theme into high school classes, reinforcing the relevance of contextualized chemistry teaching. The didactic intervention carried out in an environmental context contributed significantly to the training of future teachers, fostering meaningful learning and promoting a critical and conscious stance on the role of Chemistry in environmental issues.

The present study introduces a direct approach for classifying blood serum samples as either
positive or negative for coronavirus disease (COVID-19) by associating the electrochemical
impedance data of the sample with multivariate analysis. The hypothesis is that the systematic
alterations in blood composition resulting from a severe acute respiratory syndrome coronavirus
2 (SARS-CoV-2) infection give rise to a distinct impedance spectrum when infected serum is
subjected to analysis. A total of 201 serum samples were analyzed using the gold standard method,
reverse transcription-polymerase chain reaction (RT-PCR), which served to train and validate the
classification models. Two variations of discriminant analysis (partial least squares discriminant
analysis (PLS-DA) and principal component analysis-discriminant analysis (PCA-DA)) and a
one-class modeling approach (soft independent modeling of class analogies (SIMCA)) were used
to classify impedance data in different formats (as complex or real numbers). PCA-DA applied to
imaginary impedance spectra was found to be the most effective strategy, achieving sensitivity,
specificity, and precision of 94, 94, and 91%, respectively, with classification error rates as low as 6%. These findings are encouraging and could facilitate the development of an inexpensive and
reliable screening method for COVID-19.
Strategic Branding of National Universities of Light Industry and Fashion
Authors: Khvorostyanaya Anna
Published: February 2025

Strategic branding helps to build a recognizable image and a good business reputation by bringing the key objectives across to the target audience. A recognizable university brand attracts students and faculty while improving the business reputation for the whole industry. The national light manufacturing industry is experiencing a critical talent shortage. By increasing their attractiveness, higher education institutions of light industry and fashion may attract labor resources because their academic reputation depends on that of the industry. The author described the branding of higher education institutions that train specialists for the light industry and fashion enterprises. The research relied on the theory and methodology of strategizing developed by Professor V. L. Kvint. The topic of strategic branding in the light industry and fashion remains understudied. Most related publications registered in elibrary.ru feature digitalization, trend analysis, and historiography. This study focused on the concept and strategic approaches to academic branding. The analysis of Russian higher education institutions yielded a model of developing a university strategic brand that would attract students with good intellectual potential in the sphere of light industry and fashion. Foreign authors describe the strategic branding of higher education organizations as the result of the market economy development. In Russia, the last three decades have seen a considerable development in the strategic branding at the university level. This paper can facilitate further research and branding practice.

In the course of computational experiments carried out to study the influence of the flow tube shape on the sensitivity of measurements of the parameters of liquid mass flow as a function of the average time delay using the developed hardware and software complex, it was revealed that the model of a Coriolis flow meter with a radius of curvature of the flow tube of 30° is recommended for use in oil and gas industry as a tube geometry that is less susceptible to waxing and at the same time has sufficient sensitivity for measurement. Conclusions. A software package has been developed and tested. A relationship has been identified between the geometric shape of the flow tube of a Coriolis flow meter and the measurement sensitivity of the device, which is characterized by the fact that at high values of the radius of curvature of the tube, the sensitivity increases compared to straight-tube designs.

Background. The crisis has highlighted the need to revise the industrial policy. In ecosystem integration of industry, science, education and business it is necessary to have a balance of vertical and horizontal links, as the sustainability of the territory's development is determined by such factors as: the level of links between functional ecosystems and actors within the ecosystem. In ecosystem integration of industry, science, education and business, it is necessary to ensure a balance of vertical and horizontal links for the effective distribution of economic resources, accessibility of innovation infrastructure, knowledge and technology. The aim of the study is to develop the theory and methodology of regional integration management in the context of sustainable development of industrial territories. Materials and methods. The methodological approach proposed in the article can be used as a comprehensive toolkit for improving the sustainability of industrial territories and ecosystems. The author's approach is based on the theory of complex synergetic systems and entropy as a measure of the system state level (stationary equilibrium, nonstationary non-equilibrium and their combinations). Results. It is proved that only with the balance of all types of capitals the sustainable development of territories is possible. Sustainability assessment of industrial-territorial ecosystem of Vladimir region based on entropic approach is carried out. The primary attention is paid to the enterprises uniting around glass production. The implementation of the obtained results in the practice of territorial management will ensure the intensification of economic activity of the subjects of the Russian Federation, which will eventually affect the growth of macroeconomic indicators and the improvement of social indicators of regional development. Conclusions. Sustainable development of the territory should be considered as a process of development of the territory's potential through the formation of aggregate capital. The development of strategies of industrial territories should be carried out since collaborative relations with suppliers, customers, distributors and dealers, research centers, universities, public and governmental organizations.

Background. The need to quickly replace foreign software imports has led to significant growth in the relatively new information technology and industrial automation market. Despite the fact that companies have been automating their activities for more than 20 years, many of them have used foreign software until recently, which in modern conditions entails possible serious threats to their activities. This is what caused the growth of the domestic industrial automation market, and the rapid growth of new technologies, especially in the field of automation, gives reason to call this market innovative. At the same time, as in most markets, the established interaction chains have collapsed and business processes have become more complex. This prompted companies operating in it to offer their own business automation solutions and rebuild these chains: find new business partners, develop new interaction mechanisms. To improve the efficiency of companies in the innovative industrial automation market, it is necessary to describe the system of interaction of industrial automation market participants, understand the place of a specific company in this system, and build its activities in accordance with the mechanisms and trends operating in the market. Materials and methods. For a deeper understanding of the nature of interaction of innovative industrial automation market participants, the study will use a systems approach that will help not only to describe the behavior of the participants in the system, but also to describe the relationships existing between them and explain the interrelations between them. In addition, a systems approach will allow classifying market participants based on a specific unit of analysis and considering interactions from these positions. Results. The main elements of the system of interaction of innovative industrial automation market participants are considered. The peculiarity of the product in the market is revealed. The types of developer companies in the market and the conditions in which they are forced to work are considered, including barriers and restrictions imposed by market customers. The features of interaction of industrial automation market participants are revealed. Conclusions. It is concluded that knowledge of the specifics of interaction between innovative industrial automation market participants will increase the efficiency of the developer company and will also help to form its distinctive market advantages that will allow the company to stand out from its competitors.
