Elements of state policy and legal regulation of mining activities in the Arctic countries
Authors: Ivanova L.
Published: August 2023

The main development trend of the Arctic region is the economics based on exploitation of its resource potential. The intensive economic development of the Arctic territories largely depends on the climate change, as well as on the technical and technological development. At the same time, the Arctic economics is a complex system including various institutions as state, industrial companies, local communities. Numerous studies are devoted to the issues on harmful effects of mining activities on the economics, environmental situation, social and managerial spheres. Improvement of legal institutions in the field of nature resource management is aimed at eliminating administrative barriers and ensuring integrated and sustainable use of mineral resources.
Problems and directions of small forest business development in the Republic of Komi
Authors: Shishelov M.
Published: August 2023

The study presents the assessment results on the forest business development in the Republic of Komi. The work identifies the key problems of the forest business development with possible solutions. The small forest business has been shown to play an important social role for the rural settlements where it often is the only source of economic base formation. The first post-perestroika 30 years was a period in the Komi Republic when the total production volume was done by less than two dozen large enterprises of the complex. The monopolization of forest resources gradually decreased the number of small forest business enterprises as they could not compete for raw materials and closed. In order to maintain and develop the forest business, the enterprises should change the concept from products with a low added value, sawn timber or logging, to products of high processing levels. The regional authorities should try to restore the timber processing industrial plants in every district which will make various wood products. The promising directions are production of thermo-modified wood, woody and coniferous flour, and essential oils.
Complexity approach to frontline social work management
Authors: Webster Michael
Published: August 2023

This paper articulates an emergent complexity approach to the frontline manager-practitioner relationship within the context of a managerialist culture and the tensions between new public management (NPM) and social work ethical codes. Drawing from New Zealand perspectives but with transnational applications, a conceptual ‘coalface’ practice model for social work is proposed. Three constituents comprising professional, organisational and political cultures in which social care managers operate are extrapolated to construct the model: [1] the pervasive reality of managerialism; [2] workplace tensions arising from interrelationships between ethics, the organisation and the individual worker; and [3] an emergent, organic perception of agencies as organisations, integrating ‘whole systems’ thinking and complex adaptive approaches.The paper analyses the argument advanced by NPM theory of the interoperability of public and private management and proposes a team design that meets managerialist output and performance expectations whilst also creating an emergent framework enabling team leadership flexibility. The paper suggests that high performance can be integrated with a management approach predicated on social work values, thus offering potential solutions to job stressors and challenges facing frontline team leaders, managers, supervisors and practitioners who function in a managerialist environment.

El presente estudio expone las percepciones sociales de turistas, pobladores locales, funcionarios de gobierno, observadores de aves, pescadores y productores con relación al manejo, monitoreo, soluciones, responsabilidades y condición de la calidad del agua de la Laguna de Yuriria, Guanajuato. La información se obtuvo mediante entrevistas semiestructuradas y cuestionarios diseñados para aplicarse a distancia debido a la pandemia ocasionada por un nuevo coronavirus (COVID-19). En total, participaron 71 personas. Los datos obtenidos se procesaron a través del programa R para el Análisis de Datos Cualitativos (RQDA) y fueron agrupados en las tres dimensiones del bienestar humano (material, relacional y subjetiva). El 7.05 % del total de los entrevistados consideró que la calidad del agua es buena, el 18.30 % regular, el 42.26 % mala y el 12.67 % muy mala. El 19.72 % desconoció el tema. Los funcionarios consideran que la condición de la calidad del agua se debe a una mala gestión y administración pública. Los observadores de aves advierten que la calidad del agua es mala y que a menor calidad del agua menor biodiversidad de especies. La mayoría de los pescadores considera que la calidad del agua es regular y que la laguna mantiene la economía de sus familias y de las comunidades de La Angostura y Los Tepetates. Estas percepciones ayudaron a obtener un análisis social de la calidad del agua en la laguna y pueden derivar en el reforzamiento y la creación de estrategias para el manejo y la conservación de este cuerpo de agua.

La calidad del agua en los puertos puede verse afectada por contaminación proveniente desde tierra y/o desde el agua. Los cruceros son verdaderas ciudades flotantes, con capacidad para más de 5000 personas, generando gran cantidad de aguas sucias. Los buques poseen plantas de tratamiento reguladas internacionalmente, con distintos estándares de calidad de descarga. El objetivo del trabajo fue evaluar las características de los cruceros, de sus plantas de tratamiento y su posible impacto en la calidad del agua del Puerto Buenos Aires, Argentina. Se realizaron ocho muestreos entre octubre de 2018 y marzo de 2019 en las dársenas A, B y C del puerto y en el Río de la Plata (RDP), además se recopiló información de los cruceros amarrados al momento de los muestreos. Se censaron 21 cruceros, transportando más de 57 000 personas. La dársena B fue la que recibió mayor cantidad de cruceros (11) y personas a bordo (39 562). El 90.5 % de los cruceros cumplió con la normativa MEPC.2 (VI), el 9.5 % con la MEPC.159 (55) y ninguno con la MEPC.227 (64), la más restrictiva. Esto podría estar relacionado con que la flota que opera en esta zona de Sudamérica es más antigua que la que opera en zonas especiales con legislación más estricta. Se observaron diferencias significativas entre la calidad del agua portuaria y la del RDP. Sin embargo, no existe evidencia de un efecto directo por parte de los cruceros. Para futuras investigaciones se recomienda caracterizar los efluentes de las plantas de tratamiento y su posible efecto en el agua del puerto.
Large Strain Nonlinear Consolidation of Sand-Drained Foundations Considering Vacuum Preloading and the Variation of Radial Permeability Coefficient

Published: August 2023

The vacuum preloading method effectively strengthens the soft soil foundations with vertical drainage, which will produce a smear effect when laying sand drains. Meanwhile, the seepage of pore water and soil deformation during consolidation exhibits nonlinear characteristics. Therefore, based on Gibson's 1D large strain consolidation theory, this paper developed a more generalized large strain radical consolidation model of sand-drained soft foundations under free strain assumption. In this system, the double logarithmic compression permeability relationships for soft soils with large strain properties, the variation of the radical permeability coefficient in the smear zone, and the effect of the non-Darcy flow were all included. Then, the partial differential control equations were numerically solved by the finite difference method and validated with existing radical consolidation test results and derived analytical solutions. Finally, the influences of relevant model parameters on consolidation are discussed. The analysis shows that the greater the maximum dimensionless vacuum negative pressure P0, the faster the consolidation rate of sand-drained foundations. Meanwhile, the decrease in the negative pressure transfer coefficient k1 will result in a decreasing final settlement amount. Moreover, the consolidation rate of sand-drained foundations is slower considering the non-Darcy flow, but the final settlement is unaffected.

Published: August 2023

In the pursuit of China’s dual carbon goals, identifying spatio-temporal changes in industrial carbon emission efficiency and their influencing factors in cities at different stages of development is the key to effective formulation of countermeasures to promote the low-carbon transformation of Chinese national industry and achieve high-quality economic development. In this study, we used balanced panel data of 270 Chinese cities from 2005 to 2020 as a research object: (1) to show spatio-temporal evolution patterns in urban industrial carbon emission efficiency; (2) to analyze the aggregation characteristics of industrial carbon emission efficiency in Chinese cities using Global Moran's I statistics; and (3) to use the hierarchical regression model for panel data to assess the non-linear impact of the digital economy on the industrial carbon emission efficiency of cities. The results show the following: (1) the industrial carbon emission efficiency of Chinese cities exhibited an upward trend from 2005 to 2020, with a spatial distribution pattern of high in the south and low in the north; (2) China's urban industrial carbon emission efficiency is characterized by significant spatial autocorrelation, with increasing and stabilizing correlation, and a relatively fixed pattern of spatial agglomeration; (3) there is a significant inverted-U-shaped relationship between the digital economy and the industrial carbon emission efficiency of cities. The digital economy increases carbon emissions and inhibits industrial carbon-emission efficiency in the early stages of development, but inhibits carbon emissions and promotes industrial carbon emission efficiency in mature developmental stages. Therefore, cities at all levels should reduce pollution and carbon emissions from high-energy-consuming and high-polluting enterprises, gradually reduce carbon-intensive industries, and accelerate the digital transformation and upgrading of enterprises. Western, central and eastern regions especially should seek to promote the sharing of innovation resources, strengthen exchanges and interactions relating to scientific and technological innovation, and jointly explore coordinated development routes for the digital economy.

This study represents the first to examine the nutritional status of Moroccan football players. The aim of this research is to assess the energy and macronutrient intake of professional players from a club competing in the Moroccan professional league "Botola-Pro." Moreover, the study tries to find the potential correlation between nutritional intake and physical performance. A total of 27 professional players participated in a seven consecutive-day study, during a microcycle of the preseason period. The dietary intake was evaluated using the self-reported, complemented by a 24-hour recall. The InBody 120 bioelectrical impedance was employed for assessing body composition measurements, while the Yo-Yo test was utilized to evaluate physical performance; which estimates the maximal oxygen consumption level (VO2max). Among these players, their protein intake levels aligned with recommendations (1.6 to 2.2 g/kg of Body Mass). On the other hand, fat intake slightly surpassed the recommended values. However, carbohydrate intake was relatively subdued compared to recommendations of the Union of European Football Associations (UEFA) in the pre-season training phase. A positive correlation was observed (P-value of < 0.001 and R=0.831) between carbohydrate intake and the measure of VO2max. This suggests that an increase in carbohydrate consumption is associated with enhanced performance, especially within the range of 6 to 8 g/kg BM per day. Conversely, a negative correlation was identified (P-value of < 0.01 and R= − 0.847) between the percentage of dietary fat and the VO2max. The findings of this study highlight areas of nutrition that could be enhanced among professional football players to optimize their performance. In effect, nutritional education is necessary for this category of athletes. Thus, an individual care approach is strongly recommended.

Published: August 2023

Background: The mechanisms underlying the effect of estradiol (E2) on low-density lipoprotein cholesterol (LDL-C) levels are not completely understood, although a role for proprotein con-vertase subtilisin/kexin type 9 (PCSK9) has been proposed. We aimed to investigate the association between levels of E2, PCSK9 and lipid parameters in premenopausal women undergoing in vitro fertilization (IVF). Methods: Healthy women undergoing IVF in the Department of Obstetrics and Gynecology of the University General Hospital of Ioannina were recruited. Levels of E2, pro-protein convertase subtilisin/kexin type 9 (PCSK9), total cholesterol (TCHOL), high-density lip-oprotein cholesterol (HDL-C), LDL-C, and triglycerides (TGs) were measured 10 days after ovarian depression (E2min) and 7 days after ovarian stimulation (E2max). Results: A total of 34 consecutive healthy women aged 38 (26-46) years old who underwent a full IVF cycle were included. E2 levels increased by 329.6% from E2min to E2max (108 [47-346] to 464 [241-2471] pg/mL, p<0.05). At the same time, serum PCSK9 levels significantly decreased by 30.8% (245 ± 80 to 170 ± 64 ng/mL, p<0.05). No significant changes in TCHOL, LDL-C, TGs and HDL-C were found (-0.4%, -3.8%, -2.2%, and +5.3%, p >0.05). Conclusions: The increase in endogenous E2 production during an IVF cycle was associated with a significant decrease in serum PCSK9 levels during a 7-day period.
Gigantism in Earthworms: A Note on Gigantic Eisenia and Dendrobaena
Authors: Domínguez Jorge , Guimaraěs Afrânio
Published: August 2023

Earthworms are iteroparous organisms with indeterminate growth, i.e. they continue to increase in size throughout their life and after completion of sexual development. Terrestrial oligochaetes vary greatly in size. Depending on the species, adult earthworms can reach between 10 mm and 3 m in length and between <1 mm and >25 mm in width, with most being of length 5-15 cm. Among the more than 7000 species described to date, very few (~20) reach lengths greater than 1 m. The longest earthworm on record is Amynthas mekongianus, which is found in the mud banks of the Mekong River in Southeast Asia and which reaches almost 3 m in length. It is about the same size as Megascolides australis, the ‘Giant Gippsland Earthworm’. These atypically giant earthworm species remain a scientific curiosity in terms of their biology, but they cannot be considered cases of gigantism. Gigantism occurs when organisms are much larger than normal or exhibit excessive growth. Earthworms obtain energy from the organic matter on which they feed, and their growth mainly depends on the quality of the resource and on the species, as well as on food availability, environmental factors, which can directly or indirectly affect growth by modifying food availability, and other factors such as competition. This is particularly evident in earthworms, which display indeterminate growth and large species-dependent variations in size. The biology, life cycle and growth and reproduction rates of Eisenia fetida (Savigny 1826) and Eisenia andrei (Bouché 1972), the earthworm species most commonly used in vermicomposting and vermiculture, have been widely reported. Here we present details of the enormous growth of individual specimens of Eisenia andrei and Dendrobaena hortensis reared under particular culture conditions and fed a special diet. Individuals almost 20 times the average weight of individuals of the species have been obtained. Possible explanations for this interesting phenomenon are discussed.

Published: August 2023

Abstract: Autism spectrum disorders (ASDs) are complex, lifelong, neurodevelopmental conditions of largely unknown cause. The global prevalence of autism has increased twentyfold to thirtyfold since the earliest epidemiologic studies were conducted in the late 1960s and early 1970s. Recent reports agree on the association of ASD with the alteration of the microbiome (dysbiosis), which raises the possible role of external factors. Our study aimed at identifying antibiotic classes that might be associated with the development of ASD-related dysbiosis either promoting or inhibiting the process. Statistical comparison was made between the average yearly consumption of different antibiotic classes (1997-2020) and the number of individuals living with ASD estimated for 2023/100000 population in 30 European countries and the results were statistically analyzed. Tetracycline (J01A) showed significant positive (promoting) association with the prevalence of ASD (Pearson r: 0.373, p: 0.043. OR: 1.312, CI95%: 0.995-1.791, p: 0.065) and narrow-spectrum, beta-lactamase resistant penicillin (J01CF) (Pearson r: 0.524, p: 0.003, OR: 3.240, CI95%: 1.710-8.853, p: 0.004, Kruskal-Wallis p: 0.032). Mild, negative (inhibitory) association was observed with broad-spectrum, beta-lactamase sensitive penicillin (J01CA) (Pearson r: -0.278, p: 0.157, OR: 0.808, CI95%: 0649-0957, p: 0.028) and narrow-spectrum, beta-lactamase-sensitive penicillin (J01CE) (Pearson p: -0.032, r: 0.865, OR: 0.725, CI95%: 0.543-0.885, p: 0,009). Our findings strongly support the animal experiments when penicillin-exposed newborn mice developed "autism-like" behavior.

Peste des Petits Ruminants (PPR), a highly contagious viral disease, causes significant economic losses in sheep and goats. Laboratory diagnosis is crucial to disease control and eradication. Since PPRVs have recently adopted new hosts, genetic diversity within isolates of the same lineage is more likely than if they were host-specific, sheep and goats most often. ELISA detects antibodies and antigens in serology. However, mishandling, environmental conditions (temperature and humidity), storage, and sensitivity issues of commercially available ELISA kits prevent rapid PPR virus detection in third-world countries like Pakistan.
In the 2020-21 outbreaks in Pakistan, 325 blood samples, 19 swabs, and 6 virus tissue samples of sheep and goats were collected from Gilgit, Islamabad, and Fateh Jang. These virus isolates were submitted to NCBI for partial N gene sequencing. Antigen was prepared from indigenous virus Using semi-purified antigen from PPRV, an indirect ELISA for the detection of PPR antibodies in goat and sheep serum was developed using MW600922 grown in Vero cells. Dilutions of 1:200 serums and 1:32 antigens improve antibody detection.
The N-gene-based analysis revealed a better understanding of PPRV genetic characterization.
This study develops an RT-PCR assay to detect PPRV by targeting the N-protein gene. This assay offers an accurate and affordable diagnostic tool for PPRV and partial genome sequencing. Results described that PPRV isolates from the current study have 99.73% and 99.4% similarity to previously published Lahore and Faisalabad isolates from Pakistan, respectively. Compared to previous isolates from NCBI data, the virus showed high divergence rates with the Turkish strain. The comparative analysis between Commercial kit (c-ELISA) and I-ELISA

revealed that the former had a high sensitivity of 90.60% and specificity of 85.23% compared with the cELISA kit. By comparing I-ELISA and VNT, we find that the current assay is 100% specific and 82.14 % sensitive. Based on these results, serological surveys for PPR antibodies, on a larger scale, in small ruminants can be conducted with indirect ELISA rather than competitive ELISA.
Furthermore, the cost and storage efficiency was highly significant because the currently developed method has a low production cost, which is much lesser than the commercially available kit. Our findings demonstrated a significant breakthrough in terms of cost-effectiveness and storage efficiency, and they are highly recommended for developing countries.

INTRODUÇÃO: Um nível adequado de conhecimentos sobre alimentação e nutrição pode ser um fator importante para suportar escolhas alimentares mais saudáveis. OBJETIVOS: Avaliar o nível de conhecimento sobre alimentação e nutrição de estudantes do 1.º ciclo de estudos da área das Ciências da Saúde e os seus fatores associados. METODOLOGIA: Foi conduzido um estudo observacional transversal, que incluiu estudantes do 1.º ano do Ensino Superior da área das Ciências da Saúde no ano letivo de 2019/2020 (n=150). Os dados foram recolhidos através de um questionário estruturado de autopreenchimento. Os conhecimentos sobre alimentação/nutrição foram avaliados através de uma escala previamente testada na população portuguesa. As variáveis categóricas foram comparadas através do teste de Qui-quadrado e as variáveis quantitativas contínuas através do teste ANOVA. RESULTADOS: A percentagem média de respostas corretas na escala de conhecimentos sobre alimentação/nutrição foi de 77,9% (desvio-padrão=12,57) (variação 36%-100%). Ao analisarmos os fatores associados a um conhecimento em alimentação/nutrição elevado (>90% respostas corretas), verificou-se que este foi significativamente superior nos indivíduos que reportaram um consumo médio mais elevado de fruta e produtos hortícolas (4,6 vs. 3,2 porções/dia, p=0,019), particularmente de sopa, nos estudantes com mães mais escolarizadas (12,7 vs. 11,3 anos médios de escolaridade, p=0,039) e nos estudantes da Faculdade de Ciências da Saúde comparativamente aos da Escola Superior de Saúde (55,0% vs. 45,0%, p=0,018). CONCLUSÕES: Os estudantes da área das Ciências da Saúde mostraram um nível de conhecimentos sobre alimentação/nutrição relativamente elevado. Um maior conhecimento foi associado a um maior consumo de fruta e produtos hortícolas, uma maior escolaridade da mãe e ao local de Ensino (Faculdade/Escola).

INTRODUÇÃO: A insegurança alimentar caracteriza-se por qualquer falta de garantia do acesso regular a alimentos seguros e de valor nutricional adequado, podendo levar a hábitos alimentares inadequados e a um maior risco de obesidade. OBJETIVOS: Caracterizar e estudar as associações entre hábitos alimentares, estado estaturo-ponderal e insegurança alimentar num grupo populacional com auxílio económico para a compra de alimentos. METODOLOGIA: Estudo observacional de desenho transversal com aplicação de um questionário incluindo características sociodemográficas, estado estaturo-ponderal, hábitos alimentares, insegurança alimentar e géneros alimentícios adquiridos através do apoio social a cada representante dos agregados familiares beneficiários do apoio “+ Alimentação”, inserido no programa “Social +” do Município de Gondomar. RESULTADOS: De um total de 58 participantes, 70,7% (n = 41) era do sexo feminino e 58,6% (n = 34) vivia sozinho. Dos representantes dos agregados, 63,7% (n = 35) apresentavam excesso de peso e 77,6% (n = 45) uma adesão moderada a hábitos alimentares saudáveis, com 35,8% (n = 19) em contexto de insegurança alimentar grave. Um Índice de Massa Corporal mais elevado associou-se a maior insegurança alimentar (r = 0,380; p = 0,006) e participantes mais velhos apresentavam hábitos alimentares mais saudáveis (r = 0,348; p = 0,007). CONCLUSÕES: Mais de metade da amostra apresentou uma adesão moderada a hábitos alimentares saudáveis. Um Índice de Massa Corporal mais elevado associou-se a maior nível de insegurança alimentar nos beneficiários de apoio social para a compra de alimentos.

Em hospitais, a alimentação oferecida aos doentes é uma das ações relacionadas com o tratamento. O presente estudo teve como objetivo avaliar a aceitabilidade da dieta ligeira fornecida no almoço a doentes de um hospital universitário no sul do Brasil. A recolha foi realizada através de visitas aos doentes, entre os meses de agosto e setembro de 2021, numa ala de internamento do hospital. Para avaliar a aceitabilidade quantitativa da dieta ligeira foi utilizado o protocolo adaptado descrito no nutritionDay, contendo uma escala com cinco possíveis classificações do consumo da refeição almoço pelos doentes: 1) não ingeriu nada da refeição; 2) ingeriu ¼ (25%); 3) ingestão de ½ (50%); 4) ingestão de quase toda a refeição (75%); e 5) ingeriu toda refeição (100%). Para o consumo classificado como 1 e 2 observou-se qual item não foi aceito. A avaliação do consumo ocorreu em 46 doentes e foram analisadas 106 refeições. Todos os doentes eram do sexo masculino e com idade média de 55,7 anos (DP ± 12,5). A composição da refeição almoço das dietas ligeiras integrava os itens arroz, caldo de leguminosa, um tipo de carne e uma guarnição. Em relação a ingestão, o consumo quase total (opção 4) e total (opção 5) da refeição alcançou uma média de 84,5%. Os itens carnes e guarnição foram os alimentos com maior frequência e número absoluto de entregas, entretanto o consumo foi igual ou inferior a 50%, demonstrando uma menor aceitabilidade e um maior potencial para desperdícios. Através da análise dos resultados parece que a aceitabilidade do almoço da dieta ligeira foi satisfatória. No entanto, de uma forma geral, é necessária avaliação constante das dietas hospitalares como um recurso essencial para identificar as questões de consumo, melhoria da aceitabilidade e redução de desperdícios de alimentos.

The prevalence of gastrointestinal diseases has increased substantially in the last few years, bringing consequences not only to quality of life, but also to patients’ emotional/psychological wellbeing. Preliminary data from experimental studies suggest that using nutraceuticals as an adjuvant therapy to improve gastrointestinal symptomology may be a relevant and innovative strategy, since first line pharmacological treatments may pose severe adverse effects, drug resistance and lack of patient compliance. This narrative review aimed to explore the potential of four bioactive compounds at improving gastrointestinal symptomatology and disease management. Additionally, the mechanisms of action and dosages underlying the positive effects of these substances in improving quality of life and risk of disease relapse are also explored. According to the evidence found, peppermint oil and probiotics appear to ameliorate irritable bowel syndrome symptomatology, whereas polyphenols such as curcumin suggest a complementary effect in inducing and maintaining clinical remission among ulcerative colitis patients. Evidence regarding ginger’s effect on gastrointestinal symptoms is lacking and demonstrates little to no expression in irritable bowel syndrome nor functional dyspepsia.In conclusion, the consumption of peppermint oil, polyphenols and probiotics may be a viable adjuvant in the management of gastrointestinal diseases, associated symptomology and quality of life. However, further randomized controlled trials are warranted to elucidate on the optimal dose, safety and long-term efficacy of supplementing with these components, and particularly on the potential relevance of ginger supplementation.

Cancer cachexia is a multifactorial syndrome, associated with an underlying illness, characterized by involuntary weight loss and skeleton muscle mass impairment and reduction, with or without loss of fat mass. It emerges within a systemic inflammation and metabolic disturbance setting, entailing a significant impact in treatment toxicity, quality of life, functional capacity and mortality. Although the conventional nutritional support includes symptom management, inflammation and metabolic modulation and treatment effectiveness, it is not able to fully revert cancer cachexia. The nutritional goals are to provide adequate energy and protein intake along with a combination of anti-inflammatory agents and other nutrients. In this review we focus on the effect of certain nutrients and bioactive molecules in muscle loss, inflammation and cancer cachexia (β-hydroxy-β-methyl butyrate, branched chain amino acids, polyunsaturated fatty acids, carnitine, polyphenols and vitamin D). Food sources providing the later nutrients/molecules should be endorsed, in addition to a conventional nutritional support, as it is expected to entail specific functions in cancer cachexia.
Influence of CO and PES support modules on filtration performance of 3D printed Chitosan/AgNP/GO composite membranes

Published: August 2023

In this study, the effects of cotton (CO) and polyester (PES) fabric support modules on the filtration performance of Chitosan/silver nanoparticles/graphene oxide (CS/AgNP/GO) composite membranes modified with Dimethyl acetamide (DMAc) were investigated. The contact angle of the modified CS matrix decreased with proper blending of membrane composites, which improved fluid transport due to strongly bound water oxygen-containing functional groups present in the modified chitosan, according to the FTIR report. The experimental results revealed that both plain CO and PES fabrics can successfully serve as support modules for 3D printed CS/AgNP/GO composite membranes, increase water permeability, and effectively improve the filtration process. However, the effectiveness of the modified CS membrane separation process depends on the molecular interaction between the membrane composite structure and the support materials. The water absorbency of CO fabric is 16.3% higher than that of polyester (PES), confirming greater wettability. The CO-supported composite membranes exhibited the highest average permeation flux of 0.221 Lm− 2h− 1, while that of the PES-supported composite and unsupported modified CS membranes was 0.153 Lm− 2h− 1 and 0.127 Lm− 2h− 1, respectively, indicating that 100% plain CO and PES fabrics may serve as membrane support materials for water purification. Furthermore, the presence of particulate matter, including inactivated or active bacterial strains, on the membrane surface and low pressure could influence a reduction in permeation flux.

The one-step carbonization of low cost and abundant chitosan biopolymer in the presence of salt eutectics ZnCl2/NaCl results in nitrogen-doped carbon nanostructures (8.5% total nitrogen content). NaCl yields the spacious 3D structure, which allows external oxygen to easily reach the active sites for the oxygen reduction reaction (ORR) distinguished by their high onset potential and the maximum turnover frequency of 0.132 e site⁻¹ s⁻¹. Data clearly show that the presence of NaCl during the synthesis exhibits the formation of pores having large specific volumes and surface (specific surface area of 1217.4 m2 g− 1), and holds advantage by their pores characteristics like their micro size part which provides platform for mass transport distribution in three-dimensional N-doped catalysts for ORR. It holds advantage over sample pre-treated with LiCl in terms of the micropores specific volume and area, seen as their percentage rate, measured in the BET. Thus, the average concentration of the active site on the surface is larger.

Background
Hepcidin has been viewed as a reliable surrogate of cardiovascular disease (CVD) risk. We investigate the correlation between Hepcidin with serum lipids, triglyceride-glucose index, and High-sensitivity cardiac troponin T (Hs-cTnT) in community-based population by using Hs-cTnT as measuring indicator for myocardial injury.
Methods
We analyzed the association of baseline Hepcidin with serum lipids, triglyceride-glucose index, and Hs-cTnT levels in 1447 subjects from a community-based population in Beijing, China.
Results
There were significant differences in age, sex, smoking, SBP, HDL-C, LDL-C, Sd-LDL, PCSK9, LDL-TG, Apo EH, Lp(a), eGFR, hepcidin and Hs-cTnT between populations with or without Mets (P < 0.05). In correlation analysis, hepcidin was correlated with TG (β = 0.663; p = 0.002), sd-LDL (β = 9.893; p = 0.015), PCSK9 (β = 16.385; p < 0.001), RLP-C (β = 8.530; p = 0.011), LDL-TG (β = 4.652; p = 0.006), and TyG (r = 0.246; p < 0.001). Multiple linear regression analysis showed that baseline hepcidin (β = 0.584, 95%CI:0.236–0.932, P = 0.001) was positively correlated with follow-up Hs-cTnT levels in subjects with Mets. Additionally, HDL-C levels were negatively correlated with follow-up Hs-cTnT levels (β=−0.429, 95% CI: -0.791- -0.066, P = 0.021). In subjects with Mets, Logistics regression model showed that hepcidin was associated with elevated Hs-cTnT (HR = 2.534, 95%CI: 1.267–5.357, P < 0.05), but not for non-Mets group. Model 1 showed that high hepcidin was a risk factor for elevated Hs-cTnT independent of hepcidin, TG, Sd-LDL, PCSK-9, RLP-C, LDL-TG, Lp(a) and HDL-C in subjects with Mets (HR = 3.284; 95%CI: 1.015–10.634, P < 0.001).
Conclusions
Our findings in a Chinese cohort suggest that hepcidin is a risk factor for elevated Hs-cTnT in patients with Mets.
