Grouper bone nano-calcium and substitution long-chain triglyceride (LCT) into medium-chain triglyceride (MCT) enhanced calcium bioavailability and rat’s bone density

BACKGROUND: The most effective strategy to prevent osteopenia or osteoporosis in the old life is to consume an adequate amount of calcium from childhood through adulthood. OBJECTIVE: This study compared the bioavailability of CaCO3 which is the standard non-dairy calcium supplementation with grouper bone nano-calcium (GBN) combined with various percentages of Long-Chain Triglyceride (LCT) into Medium-Chain Triglyceride (MCT) on calcium bioavailability and rat’s bones density. METHODS: This study was carried out during the rat’s growth period, from the weaning until the rats reached 16 weeks. Thirty-five weaned rats were separated into seven groups and fed varied feeds for 12 weeks. The seven groups of feed were (1) CCa: standard feed AIN-93G, (2) C0: standard calcium deficient feed (without calcium), (3) G0: GBN + MCT:LCT 0 : 100%, (4) G25: GBN + MCT:LCT 25 : 75%, (5) G50: GBN + MCT:LCT 50 : 50%, (6) G75: GBN + MCT:LCT 75 : 25%, and (7) G100: GBN + MCT:LCT 100 : 0%. Parameters observed were serum levels of calcium, phosphorus, and alkaline phosphatase, femur bone characteristics, bone microarchitecture by histomorphometry, micro computed-tomography (μCT), and mechanical strength. RESULTS: The CCa and G100 groups had the best dietary results based on all parameters. The G100 group was superior to CCa in calcium and phosphorus bioavailability, rat’s bone strength and density. CONCLUSIONS: G100: GBN + MCT:LCT 100 : 0% group feed beneficially affected the bioavailability of calcium, was letting he rat’s bones to develop properly, had high density, and been strong throughout the growth phase.

Особенности роста сосны обыкновенной в условиях Красноярской лесостепи

The growth peculiarities of Scots pine (Pinus sylvestris L.) have been studied by the example of an even-aged pine stand of high density. A long-term research has been conducted on a permanent sample plot. The data has been collected from the stand aged from 37 to 55 years. The characteristics of individual trees and the entire stand during the growth period in the absence of external influences (cutting, windfalls, pest damage, etc.) and after improvement cuttings have been analyzed. The influence of the amount of resource available to a tree on the formation of crowns, root systems and stem wood has been investigated. The size of the available resource has been the square of the dominance area. The root system of the pine trees of the studied stands is compact in size and, despite the high stand density, due to the high content of nutrients in the soil and the absence of moisture deficiency, it sufficiently ensures intensive tree growth corresponding to the conditions of the I quality class. It has been found that under these conditions, the average area of the root system is proportional to the average square of the dominance area. It has been shown that the stem diameter at a height of 1.3 m in the absence of external influences significantly depends on the square of the dominance area. The correlation coefficient of these indicators for the studied stand at the age of 37 is 0.89. The influence of cuttings on annual radial increment has been studied using dendrochronology methods. It has been revealed that in the year following the cutting, it has increased by 1.3–2.0 times, depending on the increase in the square of the dominance area. A method has been proposed for calculating the competition coefficient as a share of the resource required for the free growth of a tree, which is redistributed between its closest neighbours. Long-term observations have shown that with competition coefficients exceeding 0.6–0.7, the stem diameter increment rate decreases significantly, and the trees develop a sparse crown extending less than 40 % of the tree height. This, in turn, leads to growth retardation and a transition to a depressed state. This, in turn, leads to growth retardation and a transition to a depressed state.

Research on the Investment Value of BYD Based on SWOT, Financial, and Valuation Methods

Against the backdrop of environmental degradation, green energy transformation is a strategic measure to address climate change and promote green development. The new energy vehicle industry is experiencing an unprecedented period of rapid growth. As a leading player in this sector, BYD's development is virtually representative of the Chinese new energy vehicle industry. SWOT analysis, financial analysis, and valuation analysis are crucial criteria for assessing the development status of a company. Through the analysis of profitability, operational capability, and P/E ratio data, the development status, operational capability, market competitiveness, and growth potential of a company can be directly reflected. The results show vertical integration of supply chain and cost advantage is the main strength of BYD, however it has the weakness of excessive dependence on Chinese government subsidies. From the perspective of financial performance, it has great profitability and its operating capacity situation is good. Moreover, the valuation shows it is worth for investment. This provides decision-makers with information and suggestions on enterprise management, investment, and financing, helping investors and managers make rational decisions.

Flexible Capacity Road Passenger Transport: History, Current, Future

Regular passenger transportation plays an important role in the life of modern society. At the same time, the financial burden of paying for its operation falls on the state budget and is the subject of periodic measures aimed at reducing this budgetary burden. Implementation of such goals is usually carried out by reducing the number of flights, which leads to a decrease in the quality of passenger service and their outflow to the personal car, which leads to an increase in motorization with all the negative attributes inherent in this phenomenon. This publication gives a literature review of scientific publications on the subject of the use of road passenger transport of dynamic capacity - trailer passenger vehicles, which in the period of growth of passenger traffic are coupled, increasing capacity, and in periods of decline - uncoupled, reducing capacity. Modern scientific and practical tendencies of this direction abroad are shown. A new approach to the organization of regular passenger transport operation in the Republic of Belarus is proposed, which consists in the daily forecasting of passenger capacity for each trip of each route with the subsequent assignment of passenger vehicles of flexible capacity to such trips, maximally corresponding to the available passenger capacity.

From Convention to Contention: La Famille de Saltimbanques and Les Demoiselles d'Avignon

In 1905 and 1907 Pablo Picasso worked on two large canvases for which multiple preparatory studies exist. These paintings marked quite different stages in the Spaniard's career. If the first one symbolized his final acceptance into the French modernist establishment, which is usually known as his Rose Period; the second was meant to be a radical break from those conventions, and a determined push to distance himself from established practices. More specifically, what took place between the two canvases was a transition from a fusion of realism and metaphor/allegory to a neo-primitive (and modern) perspective leading to quasi-abstraction. Not surprisingly, the first painting was auction for a record-breaking price in March of 1914, despite the growing political tensions between the great powers, particularly France and Germany, caused by colonial competition and old territorial grievances. Conversely, the second painting sold for much less in 1923, even though France was experiencing a period of rapid economic growth and social change: the so-called "Roaring 20s."

Growth Rate and Nutrient Uptake of Stevia rebaudiana Bertoni as Influenced by Organic Manures in Laterite Soils of Kerala, India

A field experiment was conducted to understand the effect of organic manures on the crop growth rate (CGR), relative growth rate (RGR), and nutrient uptake of stevia (Stevia rebaudiana Bertoni) from April to August of 2022 and 2023 at the Agronomy farm, Department of Agronomy, College of Agriculture, Vellanikkara, Thrissur. The experiment was laid out in randomized block design (RBD) with 7 treatments replicated thrice which consisted of different levels of organic manures viz., three levels of farmyard manure (FYM@ 5, 10, 15 t ha­-1), three levels of vermicompost (VC@ 2.5, 5, 7.5 kg ha-1) and a control. The organic manure treatments significantly affected crop growth rate (CGR) and relative growth rate (RGR) in all the growth periods. The two-year pooled mean of CGR of stevia was significantly superior in FYM@15 t ha-1 over control in all the three growth periods i.e., at 0-30 DAP, 30-45 DAP and 45 DAP to harvest. Whereas, the two-year mean of RGR of stevia was found statistically higher in FYM@15 t ha-1 over control in the first two growth periods only. The organic manure treatments had a significant influence on the plant nutrient (NPK) uptake as well in both the years. The two-year pooled mean data regarding plant uptake of nitrogen and phosphorous was found significantly higher in FYM@15 t ha-1 over control whereas statistically higher pooled mean potassium uptake by stevia was found in VC@7.5 kg ha-1 over control. Overall, the higher levels of organic manure, especially FYM, significantly improve growth and nutrient uptake in stevia.

GAME BOARD TO IMPROVE CHILDREN'S DENTAL AND ORAL HEALTH KNOWLEDGE

Background: The five-year period in the stage of child development is the golden age, which is a golden period in the period of growth and development of children. During this period, everything that is poured out and absorbed in the child will become the basis and sharp memory in the child, including the maintenance of dental health. The growth of 3 to 5-year-olds has some skills such as color naming. Children do tend to prefer to play. Children's activities while playing while learning can support growth and development and absorb learning optimally. Games that can be played while learning are putting together simple puzzles, drawing and coloring, composing and stacking block games, playing sand, clay or toy candles, singing, role-playing, playing music and board games.

Cellulose synthase-like OsCSLD4: a key regulator of agronomic traits, disease resistance, and metabolic indices in rice.

Cellulose synthase-like OsCSLD4 plays a pivotal role in regulating diverse agronomic traits, enhancing resistance against bacterial leaf blight, and modulating metabolite indices based on the multi-omics analysis in rice. To delve deeper into this complex network between agronomic traits and metabolites in rice, we have compiled a dataset encompassing genome, phenome, and metabolome, including 524 diverse accessions, 11 agronomic traits, and 841 metabolites, enabling us to pinpoint eight hotspots through GWAS. We later discovered four distinct metabolite categories, encompassing 15 metabolites that are concurrently present on the QTL qC12.1, associated with leaf angle of flag and spikelet length, and finally focused the cellulose synthase-like OsCSLD4, which was pinpointed through a rigorous process encompassing sequence variation, haplotype, ATAC, and differential expression across diverse tissues. Compared to the wild type, csld4 exhibited significant reductions in the plant height, flag leaf length, leaf width, spikelet length, 1000-grain weight, grain width, grain thickness, fertility, yield per plant, and bacterial blight resistance. However, there were significant increase in tiller numbers, degree of leaf rolling, flowering period, growth period, grain length, and empty kernel rate. Furthermore, the content of four polyphenol metabolites, excluding metabolite N-feruloyltyramine (mr1268), notably rose, whereas the levels of the other three polyphenol metabolites, smiglaside C (mr1498), 4-coumaric acid (mr1622), and smiglaside A (mr1925) decreased significantly in mutant csld4. The content of amino acid L-tyramine (mr1446) exhibited a notable increase, whereas the alkaloid trigonelline (mr1188) displayed a substantial decrease among the mutants. This study offered a comprehensive multi-omics perspective to analyze the genetic mechanism of OsCSLD4, and breeders can potentially enhance rice's yield, bacterial leaf blight resistance, and metabolite content, leading to more sustainable and profitable rice production.

Evaluation of Hospitalized Pediatric Patients in Terms of Anemia: Single-Center Experience

Introduction: Anemia, characterized by reduced hemoglobin and hematocrit levels, affects roughly one-third of the global population and is associated with increased morbidity and mortality. Iron deficiency anemia (IDA) is the most common form, particularly prevalent during childhood, a period of rapid growth. This study aimed to assess the frequency of anemia in pediatric patients hospitalized for various reasons. Material and methods: This study was conducted at SBU Bakırköy Dr. Sadi Konuk Training and Research Hospital, Department of Pediatrics, from September 1 to November 30,2021. The records of pediatric patients treated during this period were retrospectively reviewed. Patients with hematologic diseases were excluded from the study. Demographic data and laboratory results were recorded, and patients were grouped by age (0-2, 2-6, 6-12, 12-17 years) to compare laboratory values across these groups. Results: The study included 100 children, with an equal distribution of 50 girls (50%) and 50 boys (50%), hospitalized between September 1 and November 30, 2021, at SBÜ Bakırköy Dr. Sadi Konuk Training and Research Hospital. The patients' ages ranged from 1 month to 16.2 years, with a mean age of 3.34±3.90 years. The majority (59%) of patients were in the 0-2 age group, followed by 19% in the 2-6 age group, 19% in the 6-12 age group, and 3% in the 12-17 age group. It was observed that 31% of patients had chronic diseases. Hemoglobin levels were measured at 11.11±1.84 g/dL, hematocrit at 33.71±4.85%, mean corpuscular volume (MCV) at 81.35±8.48 fL, red cell distribution width (RDW) at 15.08±2.67%, iron (Fe) at 64.70±38.89 g/dL, ferritin at 228.50±200.04 μg/L, vitamin B12 at 554.83±389.46 ng/L, and folate at 11.34±6.23 ng/L. Conclusions: Anemia is a prevalent issue during childhood in our country and should be carefully considered in hospitalized pediatric patients. Upon detection, a cause-specific treatment plan must be developed to address this condition effectively.

Tropical Intraseasonal Variability as a Leading Moisture Dynamic Mode of the Warm-Pool Background State

Abstract Tropical intraseasonal variability (ISV) is dominated by the Madden–Julian oscillation (MJO), and its spatiotemporal characteristics vary with the Indo-Pacific warm-pool background on seasonal and longer timescales. Previous works have suggested ISV dynamics in various frameworks, whereas a unifying view remains challenging. Motivated by the recent advance in moisture mode theory, we revisit the ISV as a leading moisture mode modulated by varying background states derived from a reanalysis, using a moist linear baroclinic model (mLBM) improved with a simple convective scheme relating convective precipitation to tropospheric and boundary-layer moisture anomalies and simple cloud–radiative feedback representations. Under a boreal winter background state, this mLBM yielded a large-scale but local eastward-propagating mode with a phase speed of 3–5 m/s over the warm-pool region, resembling the MJO. Background lower-tropospheric winds and thermodynamic fields are important in determining the growth rate and periodicity of the leading mode, whose stability depends on cloud–radiative feedback and background state variations. We further demonstrate why the MJO is locally contained in the Indo-Pacific warm-pool region. The local thermal/moisture condition and Walker circulation greatly enhance its instability, but outside this region, this mode is heavily damped. Thus, the expansion/contraction of this warm-pool condition may enhance/reduce its instability and expand/reduce its domain of activity. Prescribing El Niño background causes eastward displacement of the wintertime ISV activity, reminiscent of the observed MJO modulations by El Niño. Under a summer background state, the eastward-propagating leading mode resembles the boreal summer ISV but biased, requiring further model improvements.

Effects of maize residue and biochar applications on soil δ13C and organic carbon sources in a subtropical paddy rice ecosystem

AbstractThis study investigates the utility of plant δ¹3C natural labeling in predicting the impacts of environmental shifts on carbon cycling within ecosystems, particularly focusing on paddy fields treated with maize (Zea mays L.) residues and biochar. Specifically, it examines how soil δ¹3C and the sources of soil organic carbon (SOC), respond in paddy fields (which cultivate C3 plants like rice) when amended with maize residues, maize biochar, and silica‐enriched biochar (derived from C4 plants). Conducted in the Fuzhou paddy fields, the experiment included control groups and treatment groups with maize residue (4 t ha⁻¹), maize biochar (4 t ha⁻¹), and silicon‐modified maize biochar (4 t ha⁻¹) during both the early and late rice growth periods. The results indicate that all soil treatments increased soil δ¹3C. The application of maize residues notably affected the δ¹3C of the upper soil profile (0–15 cm) differently from the deeper layers (15–30 cm), and it increased soil organic C more than biochar or silicon‐modified maize biochar. Soil available P (AP) and pH emerged as significant factors linking δ¹3C, influencing rice yield through changes in soil physicochemical properties. Unlike maize residues, which reduced rice yields, applications of biochar and silicon‐modified maize biochar increased rice yields. The latter, which was particularly effective in lowering SOC decomposition rates and addressing rice's silica needs, emerged as the preferred option. The study highlights maize biochar and silicon‐modified maize biochar as sustainable alternatives to maize residues for rice cultivation, enhancing soil fertility, carbon pool stability, and yields.

Effects of nutritional stress on soil fertility and antioxidant enzymes of rice in different growth periods.

Stress in plants denotes the detrimental impact of alterations in external environmental conditions on regular plant growth and development. Plants employ diverse mechanisms to mitigate or evade nutritional stress-induced damage. In order to investigate the physiological response mechanism of plants to nutritional stress and assess its impact on soil nutrient content and antioxidant enzyme activity in rice, a field experiment was conducted applying five treatments: control, nitrogen (N) deficiency, phosphorus (P) deficiency, potassium (K) deficiency, and full fertilization. Rice leaf and soil samples were concurrently gathered during both the vegetative and reproductive growth stages of rice. Analysis was conducted on soil N, P, and K levels, as well as leaf antioxidant enzyme activities, to investigate the impact of nutrient stress on rice antioxidant enzymes and soil fertility. The research findings indicate that full fertilization treatment enhanced the agronomic properties of the soil compared to the control treatment. In the N-deficiency treatment, reactive oxygen species (ROS) levels increased by 16.53-33.89% during the reproductive growth period compared to the vegetative growth period. The peroxidase (POD) activity decreased by 41.39% and superoxide dismutase (SOD) activity increased by 36.22% under K-deficiency treatment during the reproductive growth period compared to the vegetative growth period. Consequently, applying N and P fertilizer during the vegetative growth period can decrease membrane lipid peroxidation levels by 7.34-72.53%. The full fertilization treatment markedly enhanced rice yield compared to other treatments and increased the Nitrogen activation coefficient (NAC) and Phosphorus activation coefficient (PAC) in the soil, while decreasing the PAC. Elevating NAC levels can stimulate the activity or content of PRO, MDA, and RPS during the vegetative growth stage, whereas in the reproductive growth stage, it will decrease the content of ROS, PRO, and MDA. This data offers valuable insights and theoretical support for nutritional stress research.

Inter- and Intra-Annual Variations in Oak Tree Ring δ13C Values across Different Elevations and Their Climatic Responses in Qinling Mountains

The Qinling Mountains, serving as a natural geographical and climatic boundary in China, require comprehensive climatic records to elucidate the trends in climate changes across the country. While stable isotopes in tree rings are widely employed to indicate historical environmental changes, investigations into tree ring isotopes in the Qinling Mountains, particularly within the widespread broad-leaf oaks, remain limited. In this study, we investigated both intra- and inter-annual variations in the δ13C values of tree rings and their correlations with climatic signals over the past two decades for Quercus aliena var. acuteserrata, a dominant species among oak trees on the main peak of the Qinling Mountains. Our results reveal that responses to climate differ among altitudes and individual trees, with trees at higher altitudes exhibiting higher sensitivity to extreme climate, which is low temperatures and rainfall fluctuations during the growth period in intra-annual δ13C variations. Furthermore, the positive correlations are observed between temperature during growing season and both tree growth and the inter-annual δ13C variations. However, the climate signal appears to be hampered by oak-specific factors, such as intense competition among individuals and the age of trees. Therefore, we suggest a more rigorous selection of sampling and propose further investigations into isotopic fractionation processes in oaks for future studies.

Effects of different ratios of nitrogen base fertilizer to topdressing on soil nitrogen form and enzyme activity in sugar beet under shallow drip irrigation

Sugar beets account for 30% of global sugar production each year, and their byproducts are an important source of bioethanol and animal feed. Sugar beet is an important cash crop in Inner Mongolia, China. To achieve high yields and sugar content, it is essential to supply nitrogen fertilizer in accordance with the growth characteristics of sugar beet, thereby enhancing the efficiency of nitrogen fertilizer utilization. A two-year experiment was carried out in the experimental field of the Inner Mongolia Academy of Agricultural & Animal Husbandry Sciences. The impact of varying ratios of nitrogen-based fertilizer to topdressing on nitrate nitrogen and ammonium nitrogen levels in the 20–60 cm soil layer, as well as the activities of protease, urease, catalase, and sucrose in the 20–40 cm soil layer were investigated during the rapid leaf growth period and root and sugar growth period. Results indicated that different ratios of nitrogen-based fertilizer to topdressing significantly influenced the levels of nitrate nitrogen and ammonium nitrogen, and the activities of protease and urease in the 0–20 cm soil layer, with these effects diminishing as soil depth increased. The activities of catalase and sucrose were minimally impacted. Nitrogen was applied at 150 kg/ha during the growth period of sugar beet, according to the growth characteristics of sugar beet to maximize nitrogen utilization efficiency. Topdressing was completed with irrigation at the rapid growth stage. The nitrogen-based fertilizer to topdressing ratio of 6:4 resulted in optimal crop yield and sugar yield of sugar beet under shallow drip irrigation. Additionally, the activities of protease and urease in different soil treatments were significantly different, and the activities of protease and urease in the 0–40 cm soil layer were identified as useful soil physiological indicators for nitrogen utilization in sugar beet.

Breeding for flooding tolerance in rice: Advancements and future perspectives

Rice, the resilient grain, is cultivated in different types of ecosystems, from seacoast to hilly areas. Unfortunately, due to climate change, it frequently suffers from submergence stress during its growth period. Anoxic stress at the germination phase, flash flooding during the vegetative phase and water stagnation in low-lying areas are the major types of flooding in rice. When floodwaters rise, rice adapts. Some varieties stretch their stems toward the surface, gasping for air. Others remain dormant, conserving energy, like the FR13A landrace, SUB1 equips rice with underwater endurance. It orchestrates a genetic symphony, fine-tuning metabolic pathways and signalling survival. Some of the promising quantitative trait locus (QTLs) identified are qAG-9-2, which is responsible for anaerobic germination tolerance; qSUB1 for vegetative stage submergence tolerance, and qTIL12 for deep water adaptation. Identifying other novel QTLs and donors helps to breed varieties tolerant to different types of submergence stress. Along with Swarna SUB1, many mega-submergence-tolerant varieties have been developed and released for cultivation in Asia. As we cultivate these versatile survivors, we sow hope for a food-secure future.

Effects of environmentally friendly soil remediation materials on soil quality and maize production

In the precent, the reclaimed raw soil of newly renovated abandoned homestead was considered as the research object, and study the effects of different environmentally friendly soil remediation material combinations on the quality of reclaimed raw soil and maize crop production. A total of 6 improved material treatments were set up, including decomposed chicken manure(YJ), fly ash(FMH), ferrous sulfate curing agent(SHJ), ferrous sulfate curing agent+organic fertilizer (SYJ), fly ash+decomposed chicken manure(FYJ), and control treatment(CK). The research results showed that, the organic carbon content and water storage of new reclaimed raw soil exhibited a significant increasing trend after the application of different environmentally friendly modified materials(P < 0.05). Among them, the organic carbon and water storage of reclaimed soil under FYJ improved, which increased by 132.3 and 14.4 %, respectively compared with CK. During the growth period of summer maize, the plant height and yield exhibited a trend of FYJ> SYJ> YJ> FMH> SHJ> CK. The yield of maize under SYJ and FYJ treatments increased by 38.8 and 53.4 %, respectively, compared with CK. The appropriate combination of environmentally friendly soil remediation materials is helpful to improve the quality of new reclaimed raw soil, promote soil carbon sequestration, increase the comprehensive utilization rate of waste resources, increase the production performance of crops, and help rural revitalization and beautiful rural construction.

Coupling Image-Fusion Techniques with Machine Learning to Enhance Dynamic Monitoring of Nitrogen Content in Winter Wheat from UAV Multi-Source

Plant nitrogen concentration (PNC) is a key indicator reflecting the growth and development status of plants. The timely and accurate monitoring of plant PNC is of great significance for the refined management of crop nutrition in the field. The rapidly developing sensor technology provides a powerful means for monitoring crop PNC. Although RGB images have rich spatial information, they lack the spectral information of the red edge and near infrared bands, which are more sensitive to vegetation. Conversely, multispectral images offer superior spectral resolution but typically lag in spatial detail compared to RGB images. Therefore, the purpose of this study is to improve the accuracy and efficiency of crop PNC monitoring by combining the advantages of RGB images and multispectral images through image-fusion technology. This study was based on the booting, heading, and early-filling stages of winter wheat, synchronously acquiring UAV RGB and MS data, using Gram–Schmidt (GS) and principal component (PC) image-fusion methods to generate fused images and evaluate them with multiple image-quality indicators. Subsequently, models for predicting wheat PNC were constructed using machine-selection algorithms such as RF, GPR, and XGB. The results show that the RGB_B1 image contains richer image information and more image details compared to other bands. The GS image-fusion method is superior to the PC method, and the performance of fusing high-resolution RGB_B1 band images with MS images using the GS method is optimal. After image fusion, the correlation between vegetation indices (VIs) and wheat PNC has been enhanced to varying degrees in different growth periods, significantly enhancing the response ability of spectral information to wheat PNC. To comprehensively assess the potential of fused images in estimating wheat PNC, this study fully compared the performance of PNC models before and after fusion using machine learning algorithms such as Random Forest (RF), Gaussian Process Regression (GPR), and eXtreme Gradient Boosting (XGB). The results show that the model established by the fusion image has high stability and accuracy in a single growth period, multiple growth periods, different varieties, and different nitrogen treatments, making it significantly better than the MS image. The most significant enhancements were during the booting to early-filling stages, particularly with the RF algorithm, which achieved an 18.8% increase in R2, a 26.5% increase in RPD, and a 19.7% decrease in RMSE. This study provides an effective technical means for the dynamic monitoring of crop nutritional status and provides strong technical support for the precise management of crop nutrition.

Addressing these issues through targeted reforms is vital for creating a more resilient and sustainable future for the Greek banking sector. The paper provides actionable recommendations for policymakers, emphasizing the importance of strengthening regulatory frameworks, enhancing accessibility to financial services, and fostering societal trust through improved transparency. The recommendations aim to help the Greek banking sector navigate future uncertainties while supporting economic growth.

Co-operation and education: Historical perspectives

The history of the British consumer co-operative movement reveals strong affinities between co-operation and education. Following the historical chronology of the movement helps to illuminate diverse meanings and practices of co-operative education. From the early nineteenth century, through long periods of growth and subsequent decline, many educational initiatives and experiments, both informal and formal, have been visible. While each of these were products of particular times, there were many interconnections between them and they continue to be of interest to co-operative educators.

Pediatric Obesity Pharmacotherapy: State of the Science, Research Gaps, and Opportunities.

Pediatric obesity is a major public health problem, affecting nearly 20% of children and adolescents living in the United States. In 2023, the American Academy of Pediatrics released its first clinical practice guideline for the evaluation and management of child and adolescent obesity and recommended integrating health behavior and lifestyle interventions with pharmacological treatment when medically indicated. However, there is a limited evidence base to guide antiobesity medication treatment decisions in clinical practice and limited data on long-term safety during this critical period of growth and development in youth. Thus, in November of 2023, the National Institute of Diabetes and Digestive and Kidney Diseases sponsored a workshop to identify knowledge gaps and opportunities for research on the use of pharmacotherapy for obesity in children and adolescents. Leading scientific and clinical experts in obesity pathophysiology and treatment, pharmacotherapy, clinical trial design, and health equity and disparities, among others, identified gaps in clinical trial design, guidance for clinical use of medications in children and adolescents, additional treatment outcomes beyond body fat or weight, and improvement in care delivery. Adolescent patients and caregivers with lived experience of obesity and weight management were also invited to participate in a panel discussion, providing personal perspectives on living with obesity, clinical care considerations, and research needs. This article summarizes the workshop proceedings on the state of the science and identifies gaps and opportunities for future research to inform optimal and equitable medical management of children and adolescents with obesity.
