Published: December 2021

Background and Objectives: The work was aimed to determine the chronological sequence of events triggered by a fructose-rich diet (FRD) (10% w/v in the drinking water) in normal rats. Material and Methods: Serum parameters, liver and islet markers of metabolism, inflammation and oxidative stress were determined weekly for 21 days. Results: At the end of the first week, rats fed with a FRD showed an early increase in circulating triglycerides, fat liver deposit, and enzymatic activity of liver glucokinase and glucose-6-phosphate dehydrogenase (G6P-DH). After two weeks of such a diet, liver glucose-6-phosphatase (G6Pase) activity and liver oxidative stress markers were significantly increased. Liver sterol regulatory element-binding protein 1c (SREBP1c) mRNA also increased in the second week while their target genes fatty acid synthase (FAS) and glycerol-3-phosphate dehydrogenase (GPAT) enhanced their expression at the third week. Liver and pancreatic inflammation markers also enhanced their gene expression in the last week of treatment. Whereas both control and FRD rats remained normoglycemic throughout the entire period of treatment, blood insulin levels were significantly higher in FRD animals at the third week, thereby evidencing an insulin-resistant state (higher HOMA-IR, HOMA-B and HIS indexes). Pancreatic islets isolated from rats fed with a FRD for 3 weeks also increased glucose-induced insulin secretion (8.3 and 16.7 mM). Conclusions: FRD induces asynchronous changes involving early hypertriglyceridemia together with intrahepatic lipid deposit and metabolic disturbances from week one, followed by enhanced liver oxidative stress, liver and pancreas inflammation, pancreatic β-cell dysfunction, and peripheral insulin-resistance registered at the third week. Knowledge of time-course adaptation mechanisms involved in our rat model could be helpful in developing appropriate strategies to prevent the progression from prediabetes to Type 2 diabetes (T2D) triggered by unhealthy diets.
The Effect of Downsizing Packages of Energy-Dense, Nutrient-Poor Snacks and Drinks on Consumption, Intentions, and Perceptions—A Scoping Review
Authors: Liu Qingzhou , Tam Lok Yin , Rangan Anna
Published: December 2021

The single-serve packaging of discretionary foods is becoming increasingly popular, but evidence is limited on whether smaller package sizes can reduce food intake. The aim of this scoping review is to assess the effect of reducing the package size of energy-dense, nutrient-poor (EDNP) snacks and drinks on consumption, intentions, and perception, and to examine the effects of potential moderators or mediators. The search was conducted in six selected databases and grey literature sources, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for the scoping review process (PRISMA-ScR) guidelines. After screening 5562 articles, 30 articles comprising 47 intervention studies were included. Twelve of 15 studies found a significant effect in lowering the actual or intended consumption when a single smaller package was offered compared with a single larger package. When the total serving size was held constant between varying package conditions, such as a multipack, single package, or unpackaged, the results on the actual and intended consumption were inconsistent and varied according to the presence of moderators. Overall, these findings suggest that an overall reduction in the size of a single package is a more promising strategy than providing multipacks to reduce consumption. Changes to the current food environment to promote single smaller packages of EDNP snacks and drinks are necessary to support the better selection of appropriate portion sizes and reduce consumption.

Published: December 2021

Baicalein, a prominent flavonoid from the indigenous herbal plant Scutellaria baicalensis Georgi, possesses broad-spectrum anticancer activities. However, the biological effects of baicalein on nasopharyngeal carcinoma (NPC) and its underlying mechanisms remain unclarified. Thus, in this study, we examined the effects of baicalein on NPC cell lines and investigated the corresponding molecular mechanism through transcriptome profiling. In the study, four NPC cell lines were treated with various concentrations of baicalein at different time points. Cellular toxicity and proliferative inhibition of baicalein were examined by MTT assay. Metastatic phenotypes of NPC cells were investigated by wound healing, transwell, and adhesion assays. Additionally, microarray experiments were performed to determine the cellular pathways affected by baicalein. The expression and localization of the integrin β8 were validated by western immunoblotting and immunofluorescence. Our results revealed that baicalein exhibited its cytotoxicity and antiproliferative activity on all tested NPC cell lines. It also significantly inhibited metastatic phenotypes at sub-lethal concentrations. Transcriptomic analysis showed that baicalein significantly affected the focal adhesion pathway in NPC, where integrin β8 was greatly diminished. Thus, the present study results suggested that baicalein inhibits the metastatic phenotypes of NPC cells by modulating integrin β8, one of the major molecules in a focal adhesion pathway.

Published: December 2021

It is difficult to find research papers collecting comparative results about characterization studies of clear aligners. Therefore, the aim of this paper is to provide the first comparative analysis of most commercial clear aligners, in terms of their stability towards intra-oral staining agents, their physicochemical and optical properties, as well as their water absorption behavior. Five types of aligners, characterized by different techniques, are considered: Erkodur, Essix Plastic, Ghost Aligner, Zendura, and Invisalign. The obtained results show that clear aligners are made up of PETG, semi rigid PU, and a mixture of PU and PETG, with different degrees of crystallinity which affect the transparency of each aligner. In particular, the PETG-based materials reveal the highest value of short-range order and the highest properties in terms of transparency in the visible range. After 14 days of immersion into red wine and coffee, PETG and PU-based aligners reveal a perceivable change in color (NBS values from 1.5 to 3), corresponding to a loss of transparency due to the deposition of impurities on the surface. These results are particularly marked for Invisalign, showing changes towards other colors (NBS up to 35), probably due to the thermoforming process which led to the formation of a wrinkled surface entrapping the impurities.

Published: December 2021

Monitoring vegetation net primary productivity (NPP) is very important for evaluating ecosystem health. However, the nonlinear characteristics of the vegetation NPP remain unclear in the six provinces along the Maritime Silk Road in China. In this study, using NDVI and meteorological data from 1982 to 2015, NPP was estimated with the Carnegie-Ames-Stanford Approach (CASA) model based on vegetation type dynamics, and its nonlinear characteristics were explored through the ensemble empirical mode decomposition (EEMD) method. The results showed that: (1) The total NPP in the changed vegetation types caused by ecological engineering and urbanization increased but decreased in those caused by agricultural reclamation and vegetation destruction, (2) the vegetation NPP was dominated by interannual variations, mainly in the middle of the study area, while by long-term trends, mainly in the southwest and northeast, (3) for most of the vegetation types, NPP was dominated by the monotonically increasing trend. Although vegetation NPP in the urban land mainly showed a decreasing trend (monotonic decrease and decrease from increase), there were large areas in which NPP increased from decreasing. Although vegetation NPP in the farmland mainly showed increasing trends, there were large areas that faced the risk of NPP decreasing; (4) dynamical changes of vegetation type by agricultural reclamation and vegetation destruction made the NPP trend monotonically decrease in large areas, leading to ecosystem degradation, while those caused by urbanization and ecological engineering mainly made the NPP increase from decreasing, leading to later recovery from early degradation. Our results highlighted the importance of vegetation type dynamics for accurately estimating vegetation NPP, as well as for assessing their impacts, and the importance of nonlinear analysis for deepening our understanding of vegetation NPP changes.

Published: December 2021

Airborne Laser Scanning (ALS) is a technology often used to study forest areas. The main area of application of ALS in forests is collecting data to determine the height of individual trees and entire stands, tree density and stand biomass. The content of the ALS data is also classified, i.e., registered objects are identified, including the species affiliation of individual trees. Important information for forest districts includes other parameters related to the structure and share of stands and the number of trees in the forest district. The main goal of this study was to propose the new ALS data processing methodology for detecting single trees in the Samławki Forest District. The idea of the proposed methodology is to indicate a free and accessible solution for any user (at least in Poland). This new ALS data processing methodology contributes to research on the use of ALS data in forest districts to maintain up-to-date and accurate stand statistics. This methodology was based on free data from the geoportal.gov.pl portal and free software, which allowed to minimize the costs of preparing data for the needs of forestry activities. In cooperation with the Samławki Forest District, the proposed methodology was used to detect the number and heights of trees for two forest addresses 13b and 30a, and then to calculate the volume of stands. As a result, the volume of the analyzed stands was calculated, obtaining values differing from the nominal ones included in the FMP (Forest Management Plan) by about 25% and 5%, respectively, for larch and oak.

Published: December 2021

This paper proposes a method for extracting information from the parameters of a single point incremental forming (SPIF) process. The measurement of the forming force using this technology helps to avoid failures, identify optimal processes, and to implement routine control. Since forming forces are also dependent on the friction between the tool and the sheet metal, an innovative solution has been proposed to actively control the friction forces by modulating the vibrations that replace the environmentally unfriendly lubrication of contact surfaces. This study focuses on the influence of mechanical properties, process parameters and sheet thickness on the maximum forming force. Artificial Neural Network (ANN) and different machine learning (ML) algorithms have been applied to develop an efficient force prediction model. The predicted forces agreed reasonably well with the experimental results. Assuming that the variability of each input function is characterized by a normal distribution, sampling data were generated. The applicability of the models in an industrial environment is due to their relatively high performance and the ability to balance model bias and variance. The results indicate that ANN and Gaussian process regression (GPR) have been identified as the most efficient methods for developing forming force prediction models.
Multiparameter Monitoring with a Wearable Cardioverter Defibrillator
Authors: Rohrer Ursula , Manninger Martin , Zirlik Andreas , Scherr Daniel
Published: December 2021

A wearable cardioverter-defibrillator (WCD) is a temporary treatment option for patients at high risk for sudden cardiac death (SCD) and for patients who are temporarily not candidates for an implantable cardioverter defibrillator (ICD). In addition, the need for telemedical concepts in the detection and treatment of heart failure (HF) and its arrhythmias is growing. The WCD has evolved from a shock device detecting malignant ventricular arrhythmias (VA) and treating them with shocks to a heart-failure-monitoring device that captures physical activity and cardioacoustic biomarkers as surrogate parameters for HF to help the treating physician surveil and guide the HF therapy of each individual patient. In addition to its important role in preventing SCD, the WCD could become an important tool in heart failure treatment by helping prevent HF events by detecting imminent decompensation via remote monitoring and monitoring therapy success.
Using Sustainability-Oriented Developer Obligations and Public Land Development to Create Public Value
Authors: Candel Melissa
Published: December 2021

Swedish municipalities use negotiable developer obligations and public land development in sustainability-profiled districts to achieve various public sustainability objectives. They initiate and govern these districts, which act as models for sustainable urban development and testbeds for new sustainability-related policies, using municipally owned land. Public land development in Sweden enables municipalities to include sustainability-oriented negotiable developer obligations in development agreements. The aim of the study is to investigate how Swedish municipalities use sustainability-oriented negotiable developer obligations together with public land development, and to identify what public value outcomes they currently seek to create by using these public value capture instruments. Sustainability-oriented negotiable developer obligations are investigated in relation to municipalities’ desired public value outcomes in five sustainability-profiled district developments in different Swedish municipalities. Findings illustrate that Swedish municipalities use negotiable developer obligations to create ecological, social and cultural, political, and economic public value outcomes. This calls for more research investigating different forms of value and value creation in relation to public value capture instruments.

Published: December 2021

In this study, we used publicly available data from the Centrum e-Zdrowia (CeZ) Polish Databank proposing a possible correlation between influenza vaccination and mortality due to COVID-19. We limited our search to the patients with positive COVID‑19 laboratory tests from 1 January 2020 to 31 March 2021 and who filled a prescription for any influenza vaccine during the 2019–2020 influenza season. In total, we included 116,277 patients and used a generalized linear model to analyze the data. We found out that patients aged 60+ who received an influenza vaccination have a lower probability of death caused by COVID-19 in comparison to unvaccinated, and the magnitude of this difference grows with age. For people below 60 years old, we did not observe an influence of the vaccination. Our results suggest a potential protective effect of the influenza vaccine on COVID-19 mortality of the elderly. Administration of the influenza vaccine before the influenza season would reduce the burden of increased influenza incidence, the risk of influenza and COVID‑19 coinfection and render the essential medical resources accessible to cope with another wave of COVID-19. To our knowledge, this is the first study showing a correlation between influenza vaccination and the COVID-19 mortality rate in Poland.

Published: December 2021

Forests host diverse ecosystems that involve various habitats. There are many complex interactions between living and non-living things in most forests. It is important to conduct observations and assessments in large forestlands where short-term and long-term direct or indirect negative impacts may occur so that they are known and measured. Scientific studies have been carried out by utilizing the various data offered by today's advanced technology with satellite imagery becoming more readily available. In this study, differenced Normalized Burn Ratio (dNBR=∆NBR) and satellite images with two different resolutions were used to generate pre- and post-wildfire spatial data. An area affected by wildfire in the Mediterranean Region of Turkey was selected as the study area. Google Earth Engine (GEE) and Geographic Information System (GIS) were used to delineate areas affected by wildfire using Sentinel-2 and Landsat 8 multispectral imagery. In order to compare the differences between the two sets of imagery, burn severity levels (low, medium-low, medium-high, and highest) and the effect of water surface were considered. For the most impacted burnt lands, areas detected with Sentinel 2 and Landsat 8 are 31.90% and 32.59%, respectively. However, burn severity classes were also observed in water surface areas likely due to interactions between land cover and water reflectance. The overall results support the use of both satellite platforms and the dNBR for burn severity mapping in medium- and large-scale post-wildfire studies.

Movilidad urbana post pandemia: fuerzas en pugna con sentidos de sustentabilidad contrapuestos
Authors: Borthagaray Andrés , Gutiérrez Andrea
Published: December 2021

Este ensayo aporta una reflexión orientada a sintetizar, explorar e interpretar algunas experiencias y tendencias sobre esta encrucijada significativa planteada por la pandemia y sobre la consecuente posibilidad de cambios a futuro. Las restricciones a la movilidad han generado consecuencias en actividades esenciales, como el trabajo, la educación y el propio acceso a la salud. Si bien han existido medidas y alternativas de mitigación, estas se han dado y distribuido de modo desigual. Como parte de los escenarios posteriores a la emergencia, se proyecta una nueva organización de los tiempos y los espacios de la movilidad, y por su intermedio, del territorio y la distribución de oportunidades. Pero esta proyección permite anticipar tendencias encontradas que podrían incluso agudizar la anterior polarización. La movilidad activa, las mejoras de un transporte público adaptado a una demanda en evolución y la organización social de una movilidad sustentable se contraponen con una huida de la ciudad, un refugio en soluciones individuales para quienes pueden afrontarlas y una rigidez en la organización de servicios desde la oferta, llevados por las inercias territoriales, sociales e institucionales que generan una fuerte tracción ante los cambios de curso.

Published: December 2021

A demanda por deslocamentos reduziu-se globalmente, com impactos sem precedentes no transporte público pela pandemia da Covid-19. As razões vinculam-se a medidas de restrições a aglomerações, a decisões individuais de evitar viagens para diminuir exposição ao risco, e como consequência o aumento no uso do automóvel. O Brasil que apresentava tendência de redução de demanda enfrenta a pandemia como um problema adicional que colocou em risco a sustentabilidade financeira dos serviços. Nesse contexto de perplexidade, foi promovido um Fórum de Discussão onde buscou-se obter elementos para propor diretrizes e ações estratégicas para apoiar o Poder Público e os operadores a enfrentarem esse desafio. Para sintetizar, estruturar e hierarquizar problemas, para superar a insustentabilidade do modelo atual de transporte público agravado pela pandemia foram aplicados instrumentos combinados de análise de causa e efeito de Ishikawa, de análise de Pareto e de planejamento estratégico pela Matriz de Marco Lógico. Estabeleceu-se como objetivo superior a oferta de transportes seguros e economicamente sustentáveis e objetivos específicos de redução de risco à exposição, reformulação das redes com ajuste oferta-demanda, apoio a modos ativos e disponibilização de informações por aplicativos. Essas estratégicas exigem um novo papel do poder público e novas formas de financiamento ao transporte.

Published: December 2021

The aim of this study was to evaluate the clinical and radiographic success and parental acceptance of a preformed composite crown (PTC) for primary molars and compare with that of conventional stainless steel crowns (SSC). A total of 38 children (Girls:12, Boys:26) in five-nine age range, selected from among patients attending the pediatric dentistry clinic. Seventy-sixth crowns were applied in a split-mouth design with a random allocation for mandibular primary 1st and 2nd molars. Assessment of the clinical and radiographic performance of the restorations was performed by two calibrated examiners during 12-month follow-up period and parental satisfaction was determined for both crowns.Total clinical success rates were 100% and 63% for SSCs and PTCs, respectively, at the end of 12-month follow-up, and the difference was statistically significant (p<0.05). Despite the high rates of cementation and endodontic failures, parents were much more satisfied with PTCs (p<0.05). It has been determined that SSCs is more successful than PTCs, but PTCs were preferred by parents due to their aesthetic features.Despite the high rate of aesthetic satisfaction in the PTC group, studies are needed to evaluate the coronal leakage factor in terms of its potential to cause the problems of "falling out of crowns" and "endodontic problems", observed as clinical failure.

Published: December 2021

Polyurethane nanocomposites are promising materials in many industries, they have superior physical and mechanical properties compared to the original polyurethane. This paper presents an analysis of the physical and mechanical properties of polyurethane nano-composites with various types of fillers such as organoclays, carbon nanotubes, polyhedral oligomeric silse-squioxanes, graphene, graphene oxide, polytetrafluoroethylene, and metal nanoparticles. The concentration-dependent effects in changing the structure and properties of polyurethane composites under the influence of the added fillers were also considered. It is noted that the values of physical and mechanical properties are influenced by the uniform distribution of nanofiller particles in the composite and their chemical modification. It was found that with a uniform distribution of nanoparticles in the polymer matrix, the physicomechanical properties of the resulting composites increase.

The use of lactam-containing complex salts (LCS) with the functions of dispersants, apparatuses and crosslinking agents made it possible to obtain elastomers with a high (at least 300 wt.% per 100 wt.h. of rubber), containing modified carboxymethyl cellulose for the cuff of a packer device capable of performing the necessary shut-off functions in contact with highly concentrated, at least 25% aqueous solutions of mineral salts - NaCl and CaCl2. The achieved effect is expressed in the ability of LCS to disperse water-swelling polymers (GNP), to have an appreting effect on GNP particles, thereby preventing their agglomeration, as well as to create additional chemisorption bonds in the rubber matrix. As a result, a developed network of interface boundaries is obtained, which contributes to the rapid penetration of aqueous solutions of mineral salts into the array of elastomeric composition.

In this work, graft copolymers of chitosan with trimethylmethacryloxyethylammonium methyl sulfate were synthesized by the method of controlled radical polymerization, and it was found that replacing the dimethylformamide aprotic solvent with water increases the degree of grafting. With the aim of the possible use of chitosan copolymers as a functional component for regulating the water-swelling properties of elastomers, the kinetics of swelling of the samples was investigated. An increase in the degree of swelling of the copolymers in comparison with the initial chitosan was revealed, and the influence of the molecular weight and the conditions of their synthesis was established.

Досліджено розвиток професійної хореографічної освіти в Україні у структурі нав-чальних закладів культури і мистецтва. На основі ретроспективного, системно-структурного та педагогічного аналізу з’ясовано, що інституційна хореографічна підготовка виконавських, балет-мейстерських, культурно-просвітницьких та хореографічно-педагогічних кадрів в Україні актуалізована з другої половини XX століття. Вона реалізовувалася в різних типах навчальних закладів гуманітарного спрямування в різноманітті організаційних форм та освітніх ступенів. Метою публікації визначено дослідження нормативного забезпечення, стратегій, змістових напрямів підготовки хореографічних кадрів у структурі мистецької освіти в Україні. Професійну хореографічну освіту інтерпретовано як самостійну галузь мистецької освіти зі своєю структурою, інституційно оформленою у профільних закладах фахової передвищої та вищої школи. Теоретичне узагальнення джерельної бази дослідження дозволило виявити, що кожна ланка хореографічної освіти, підпорядковуючись загальним закономірностям розвитку мистецької освіти, мала свої цілі та завдання. Спрямованість змістового наповнення хореографічного навчання здобувачів варіювала в залежності від цільових настанов, кваліфікаційних характеристик обраної спеціальності, а також сфери її практичного застосування у мистецькій та педагогічній галузях. Узагальнено, що хореографічна підготовка була спрямована на формування у майбутніх фахівців компетентностей, необхідних для успішної професійної самореалізації в якості керівника хореографічного колективу, організато-ра хореографічного аматорства, культорганізатора, методиста хореографічного жанру, педагога-хореографа в різних типах культурно-просвітницьких закладів. Зазначено, що наступність і неперервність розвитку професійного та особистісного потенціалу фахівця у сфері хореографічної діяльності забезпечують різні форми підвищення кваліфікації, актуалізовані в умовах сьогодення
