Crianças e adolescentes em movimento: os efeitos das mudanças climáticas no contexto brasileiro
Authors: Duarte Milena Pereira
Published: February 2024

Tendo em vista os crescentes impactos de eventos decorridos das mudanças climáticas no Brasil, faz-se essencial compreender como eles têm influenciado o movimento migratório da população. Sendo as crianças e adolescentes o público usualmente mais vulnerável desse fenômeno, o presente artigo tem como objetivo buscar identificar o contexto em que os deslocamentos infantojuvenis têm acontecido como consequências dos desastres naturais no país. Assim, é desenvolvida uma revisão bibliográfica da temática que visa mapear e quantificar a média de mudanças de menores de idade por eventos climáticos extremos, utilizando principalmente, para tal finalidade, os dados coletados do relatório do Fundo das Nações Unidas para a Infância, publicado em 2023. Nesse sentido, a pesquisa contribui para a construção de mais informações nacionais acerca do assunto que carece de dados detalhados e busca evidenciar os maiores motivadores das mudanças de crianças de seus lares no âmbito indicado. Por meio das análises, as inundações corresponderam ao maior número de meninos e meninas deslocados entre os anos de 2016 a 2021, seguidas das tempestades, secas e incêndios florestais, que atingiram diversos estados do país. A partir dos estudos aplicados, a compreensão dos procedimentos mais eficazes a serem desenvolvidos para dar assistência às famílias é ampliada, o que garante a proteção, segurança e bem-estar das crianças em face às decorrências dos efeitos das mudanças climáticas.

Authors: Zeynep Sen Yilmaz , Merve Köseoğlu , Funda Bayindir
Published: February 2024

Background: Obstructive Sleep Apnea (OSA) is difficult to detect when dentists or dentistry students are not well-trained on this subject. Including this topic in the dental curriculum may help students with diagnosing patients who have OSA. Objectives: This cross-sectional study was conducted to compare the changes in the knowledge and attitudes of clinical dentistry students at Atatürk University, Turkey about OSA before and after education about this topic. Materials and methods: In this study, 227 participants were asked to reply OSAKA questionnaire consisting of 23 questions (18 knowledge questions and 5 attitude evaluation questions) before and after the lesson about OSA. Obtained data were analyzed with descriptive statistics, Chi-square, and Spearman analyses. The statistical significance level was set at α < 0.05. Results: The mean knowledge score was 4.91 before the lesson and 13.0 after the class. Overall, correct answer rates increased significantly (p = 0.010) as well. Conclusion: Participants' knowledge about OSA increased and their attitudes became more positive after the lesson. Pre-graduate training may increase dentistry students’ knowledge scores and improve their attitudes regarding OSA.

Published: February 2024

This study aimed to investigate the effects of auxin types and their concentrations on rooting of the rootstock cuttings and BA on grafting. First, IBA, NAA or IBA+NAA, each at 0, 1000, 2000, and 3000 ppm were used as treatments to study rooting of Piper colubrinum. In the second experiment, BA (0 and 50 ppm) was applied to P. nigrum scion clones of Natar-1 and Petaling-2, before being grafted to the rootstocks. Results showed, that all types of auxins (IBA, NAA or IBA+NAA) induced rooting and shoot growth, and the increase of auxin concentrations led to the increase of rooting. However, their effectiveness was different. NAA and IBA+NAA were superior to IBA, and at 2000 ppm, IBA+NAA resulted in the best plant growth, as indicated by higher values of both rooting and shoot growth parameters. Compared to control, BA treatment on scions resulted in higher grafting success (80% vs. 93%) for Natar-1, and (73% vs.100%) for Petaling-2 clones.  BA treatment on scions also induced more calluses in the graft union and better shoot growth. To our knowledge, this is the first report on the use of BA to increase success of grafting between P. nigrum and P. colubrinum.

Published: February 2024

An experiment is conducted to investigate the effects of cultural techniques on pepper yellow leaf curl disease caused by Pepper yellow leaf curl Indonesia virus (PepYLCIV). The investigation is conducted in the area where the disease has been endemic and Bemisia tabaci is abundant. Four cultural techniques are applied in separate lands and cannot interfere with each other. The methods applied are seed treatment, intercropping, trap cropping, and physical barrier. Seeds harvested from infected plants are used for seed treatment experiments, and local farmers use commercial sources for other experiments. The results confirmed that PepYLCIV was a seed-borne virus affected by hot water treatment at 65oC for 30 minutes. Turmeric crude extract could reduce the incidence and severity of the disease. The tomato is a better intercrop than eggplant, mung bean, and soybean in reducing disease incidence, but their effects on disease severity and yield reduction were not significantly different. Basil and marigolds were better barrier crops compared to cosmos and zinnia. A 125 cm high physical barrier using 50 mesh cheesecloth could reduce the disease incidence, but not the lower ones. Under different cultural techniques, PepYLCIV causes a 40.00–52.32% chili yield reduction.

Published: February 2024

Bacterial stalk rot is one of the important diseases in maize caused by Dickeya zeae. Infection of this disease can lead to a considerable amount of loss in yield, with up to 98 percent loss of yield. The use of resistant materials is the most effective approach to managing bacterial stalk rot in maize. This study evaluates a large-scale phenotypic screening of 624 maize lines against bacterial stalk rot, divided into two groups based on a heterotic pool. These lines are used in a commercial breeding program in Indonesia. This study develops a stabbing method with a large gauge hypodermic needle, allowing for scalability in delivering inoculum while performing large-scale line evaluation. The result from ANOVA reveals a significant (P<0.05) effect of lines, day after infection, and interaction between day after infection and group. Group two displays fewer resistant lines compared to group one. This work presents a method for large-scale line evaluation for resistance against bacterial stalk rot, where the information obtained can be used in industrial breeding programs for routine material screening during the development of new lines or hybrids and for genomic studies of bacterial stalk rot resistance.

«Ideology at Its Purest»: Whose modernism?
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Demchenko Dariia
Published: February 2024

In this review, I aim to analyse the catalogue «In the Eye of the Storm: Modernism in Ukraine, 1900–1930s». The project bearing the same name, for which the catalogue was prepared, commenced in the autumn of 2022 at the Thyssen-Bornemisza Museum (Madrid), essentially becoming the first extensive exhibition dedicated to the work of modernist artists in the territory of contemporary Ukraine since 2007. Modernism is an international phenomenon characterised by various movements and ideas, that incorporate local elements into art. However, post-Soviet states instrumentalised knowledge of modernism, seeking to recreate a «tradition» disrupted by the Soviet regime. This involves juxtaposing the modernist movement with socialist realism. The authors of the reviewed publication also adopted this approach: to construct a «national» past, they resorted to the cultural nationalisation of modernism. This is achieved, in part, by using terms such as «Ukrainian modernism/avant-garde», blending ideological traditions of modernity and modernism, and so on. In my text, I aim to clarify these processes and demonstrate the inappropriateness of defining the national identity of artists who worked in the territory of contemporary Ukraine from the 1900s to the 1930s, as well as the appropriation of modernism by one country or another.

Psephellus huber-morathii (PH) is an endemic species in the Eastern Anatolia Region. In this study, besides the biological activities of the 70% methanol extract of PH, its comprehensive phytochemical composition was investigated. The phenolic composition of the PH extract was analyzed using the UHPLC-MS/MS method. To evaluate its antimicrobial characteristics, the microdilution technique was employed. The antioxidant capabilities and total phenolic and flavonoid contents of the extract were determined using the spectrophotometer. Additionally, the effects of the extracts on cell proliferation and NCI-60 survival parameter values were assessed using the MTT assay. Quinic acid and chlorogenic acid were major compounds. The extract showed high antioxidant activity in DPPH (IC50:13.9±0.4 μg mL-1) and FRAP (61.3±2.3 mg TE g extract-1) methods. The total phenolic and flavonoid contents of the extract were found as 52.2±1.9 mg GAE g extract-1 and 28.6±0.9 mg QE g extract-1, respectively. Discussion: The extract showed low antiproliferative activity against normal lung and retinal cell lines, promising anticancer effects on gynecological and colon cancer cells, and moderate antimicrobial activity against Bacillus cereus and Enterococcus faecium. The study demonstrated the medicinal potential and value of PH extract against infectious diseases and cancer.

Authors: Hestiantoro Andon , Saraswati Jaya , Prasetya David Eka , Sandra Ferry , Muharam Raden , Pratama Gita , Harzif Achmad Kemal
Published: February 2024

BACKGROUND: Insulin resistance (IR) is considered as the main driver of polycystic ovary syndrome (PCOS) pathogenesis. In PCOS condition, IR is frequently related to glucose, anthropometric profile, lipid profile, and hormone profile parameters. However, not all PCOS phenotype show IR. Therefore, this study was conducted to determine the association the parameters mentioned above in PCOS subjects with and without IR.METHODS: Fifty PCOS women with IR and 26 PCOS women without IR were recruited. All subjects underwent physical examination for measurement of weight, waist circumference (WC), and body mass index (BMI). Ferriman Gallwey Score (FGS) was used to evaluate hirsutism. Blood sample was taken from each subject for measurement of fasting glucose, postprandial glucose, fasting insulin, low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol, triglyceride (TG), sex hormone binding globulin (SHBG), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), follicle stimulating hormone (FSH), and prolactin. Homeostatic model assessment for IR (HOMA-IR), TG-glucose index (TyGI), and free testosterone index (FTI) were then calculated.RESULTS: From all the parameters examined, only fasting insulin (p<0.001), HOMA-IR (p<0.001), SHBG (p=0.012), TG (p<0.001), and TyGI (p=0.008) that show significant differences between PCOS subjects with and without IR. After multivariate analysis, TyGI was found to have strong association with IR occurrence in PCOS subjects (p=0.005) with an odd ratio of 5.26 (1.65–16.74).CONCLUSION: TyGI appears to have a significant association with the IR occurrence in PCOS subjects. Hence, it can be suggested that TyGI could be an important marker for PCOS women with IR.KEYWORDS: insulin resistance, lipid metabolism, polycystic ovary syndrome, triglyceride-glucose index

Autonomic Dysfunction in Psychiatric Disorders
Authors: GÖÇEN Hande Besna , ÖZDEN Ali Veysel
Published: February 2024

The autonomic nervous system and its dysfunction are associated with many diseases. For a healthy individual, it is essential that the sympathetic and parasympathetic systems are balanced and functioning at a high capacity. Psychiatric disorders often exhibit disruptions in the activity of the vagus nerve, which can lead to autonomic dysfunction. People with psychiatric disorders, including panic disorder, depression, bipolar disorder, schizophrenia, post-traumatic stress disorder, anxiety disorders, and substance addiction, often show reduced heart rate variability. Heart rate variability is a reliable marker for assessing autonomic functions, and decreased heart rate variability in individuals with psychiatric disorders can lead to an increased risk of sudden cardiac death. Autonomic dysfunction is observed in psychiatric disorders, and it occurs during the course of the illness, not necessarily at its onset. Autonomic dysfunction accelerates the progression of the disease. Therefore, controlling autonomic functions is crucial. This can help reduce disease symptoms and decrease the morbidity and mortality caused by autonomic dysfunction."

Purpose: Research on rib fracture management has exponentially increased. Predicting fracture patterns based on the mechanism of injury (MOI) and other possible correlations may improve resource allocation and injury prevention strategies. The Chest Injury International Database (CIID) is the largest prospective repository of the operative and nonoperative management of patients with severe chest wall trauma. The purpose of this study was to determine whether the MOI is associated with the resulting rib fracture patterns. We hypothesized that specific MOIs would be associated with distinct rib fracture patterns.Methods: The CIID was queried to analyze fracture patterns based on the MOI. Patients were stratified by MOI: falls, motor vehicle collisions (MVCs), motorcycle collisions (MCCs), automobile-pedestrian collisions, and bicycle collisions. Fracture locations, associated injuries, and patient-specific variables were recorded. Heat maps were created to display the fracture incidence by rib location. Results: The study cohort consisted of 1,121 patients with a median RibScore of 2 (0–3) and 9,353 fractures. The average age was 57±20 years, and 64% of patients were male. By MOI, the number of patients and fractures were as follows: falls (474 patients, 3,360 fractures), MVCs (353 patients, 3,268 fractures), MCCs (165 patients, 1,505 fractures), automobile-pedestrian collisions (70 patients, 713 fractures), and bicycle collisions (59 patients, 507 fractures). The most commonly injured rib was the sixth rib, and the most common fracture location was lateral. Statistically significant differences in the location and patterns of fractures were identified comparing each MOI, except for MCCs versus bicycle collisions.Conclusions: Different mechanisms of injury result in distinct rib fracture patterns. These different patterns should be considered in the workup and management of patients with thoracic injuries. Given these significant differences, future studies should account for both fracture location and the MOI to better define what populations benefit from surgical versus nonoperative management.
Standardizing outcomes in metabolic bariatric surgery - more than meets the eye, less than counts the scale
Authors: Athanasios G. Pantelis
Published: February 2024

The era of precision medicine necessitates standardization in reporting outcomes, in order to provide a common ground of communication among specialists and yield objective measurements at the same time. Although metabolic bariatric surgery spearheads innovation and standardization with regard to technique, this is not the case when measuring outcomes, particularly regarding weight recurrence. The multitude of definitions of weight regain and insufficient weight loss stems not only from a lack of consensus but also from the inherent deficiencies of weight- and BMI-based formulas to incorporate a global and comprehensive assessment for obesity. In this Perspective, we investigate current knowledge as well as potential amendments that will ameliorate our ability to assess weight recurrence and improve the services that we offer to people living with obesity.

Authors: Mesquita Jessica Lea , Escott Carlos , Graça António , De Freitas Victor , Morata António
Published: February 2024

Context & aim: The two major categories of Port wines, Tawny and Ruby, are defined by their ageing conditions, with associated oxidative conditions being much more pronounced in the case of the former than the latter. The main aim of this study was to determine if, independently of the producer, all Port wines can be grouped into these styles based on their chromatic and pigment characteristics.
Methods: A total of 32 Port wine samples comprising eight different styles were provided by five different producers of the Douro region in Portugal for this work. All the samples were filtered prior to analysis for anthocyanin determination using an HPLC-DAD-ESI/MS, and unfiltered samples were used for the determination of colour parameters and CIE Lab coordinates. The samples were measured in triplicate for statistical analysis.
Results: The chromatic analysis of the Port wines showed Ruby style Ports to have a higher colour intensity and lower hue (°) than Tawny style Ports. The PCA analysis of colour parameters and CIE Lab coordinates clearly shows two separate clusters representing Ruby styles and Tawny styles respectively. Overall, Tawny style Ports had traces of or non-detected anthocyanins monoglucosides, a few styles having < 10 mg/L in the form of malvidin-3-O-glucoside equivalent; meanwhile Ruby styles showed higher concentrations of anthocyanins as detected by HPLC, sometimes reaching values close to 100 mg/L. The major anthocyanin family found across all wines (even in trace amounts) were pyranoanthocyanins, specifically vitisin A and coumaroylated vitisin A.
Main conclusions: The results prove that in terms of all the parameters studied there is a clear division between the two major styles of Port wines, which can be attributed to the differences between the ageing process of these two types of wines.

In the course of scientific research the chemical composition, physico-chemical and antioxidant properties of local grape and secondary raw materials of winemaking industry were studied, the technology of sausage production with the addition of grape extract of high nutritional value was substantiated and developed. Information on the antioxidant activity of grape raw materials growing in the territory of the Republic of Bashkortostan has been obtained. The presence of biologically active substances with antioxidant and antioxidant properties in the grape extract is a promising factor for the introduction of the extract in food products, including meat products, to enrich them with antioxidants. Analyzing the results of the study, we can conclude that the use of 3% grape squeeze extract will enrich meat products with a sufficient amount of antioxidants of natural plant origin. In the course of research it was found that the extract from grape squeeze has a rich dark blue color due to the high content of anthocyanins, which can affect the organoleptic characteristics of the finished meat product, in connection with that the color characteristics of the minced meat samples were analyzed. An important indicator in our scientific research was the preservation of antioxidants in the process of preparation of the extract and introduction into the minced meat. In this regard, the degree of preservation of calculated and actual total content of antioxidants in different objects was further studied. The technology of obtaining new types of food products - sausages, based on the use of grape extracts has been scientifically substantiated. It has been established that within the framework of the modern theory of positive nutrition it is more reasonable to add grape squeeze extract instead of fatty meat raw materials. This allows to enrich sausage products not only with mineral substances, organic and polyunsaturated fatty acids, vitamins, amino acids, pectin substances, but also to obtain biologically valuable meat products based on secondary grape raw materials.

Proper nutrition plays a key role in achieving successful results in physical activity. It not only provides the body with the necessary nutrients, but also helps maintain energy and restore muscles after training. One common nutritional strategy is to distribute nutrients over time. This means it's important to consume a combination of proteins, carbohydrates, and fats regardless of the time of day or workout. However, the proportions of intake of these components can affect the intensity and duration of training. Particular attention should be paid to the post-workout period, as it is considered the most important for nutrient intake and recovery of the body. At this point, the body needs nutrients to repair damaged muscles and energy stores. The correct ratio of nutrients at this time contributes to the improvement of body composition and physical performance. The article provides tips and advice on choosing the right products, taking into account the characteristics of training and individual needs of the body. Advice on nutrient and fluid intake is also provided. It is important to consume enough protein for muscle maintenance and repair, as well as carbohydrates for energy. Proper nutrition is the basis for achieving high results in physical activity, increasing efficiency and effective recovery after training. The purpose of the work is to understand the importance of nutrition in sports and the ability to correctly distribute nutrients, which is an important step towards achieving sports and physical goals.

Studies aimed at determining the features of printing on biocomposite polymer materials were carried out. It has been found that the untreated composite films have a low adhesion strength at the composite film-paint interface, the surface tension did not exceed 28 mN/m, and the contact wetting angle was greater than 80 degrees. When the surface is activated by the "corona" discharge method, the adhesion properties appear to a greater extent, and with an increase in the processing stress of the "corona" discharge, the adhesion strength also increases. Thus, in a 25 kV surface treatment, the surface tension for the test composites was estimated to be above 40 mN/m and the contact wetting angle was less than 45 degrees. For BHA based on LDPE and TPC of various bases (corn, pea, rice), adhesion strength was evaluated in the range from 2.9 to 3.5 N/cm2, for PCM based on LDPE and ORD - 29 N/cm2. The result of this work is an increase in surface tension due to the appearance of polar groups on the surface of composite films, in particular oxygen-containing C-O and C = O, as confirmed by Fourier IR spectroscopy. Although the adhesion strength at the film-paint interface is increased when the surface of the composite films is activated, it has been observed that for LDPE-based BHC and thermoplastic starch, the adhesion properties are not constant and decrease over time. After two weeks, adhesion strength was evaluated, on average, 1.4 N/cm2. Most likely, BHCs do not transition to the electret state when the surface is activated by "corona" discharge, and external factors such as temperature and humidity act, as a result of which the number of polar groups on the surface decreases. On the contrary, a slight decrease in adhesion strength from 29 to 27 N/cm2 was observed for PCM based on LDPE and OPD, which is due to the chemical nature of the starting components.

Films based on PVA solutions are currently attracting increasing attention due to their high transparency, barrier properties and environmentally friendly nature. This is due to the fact that PVA films have greater flexibility, transparency, impact strength and lower cost than other packaging materials. When discarded, PVA can decompose in the natural environment without adding to the pollution. The article is devoted to the study of film materials obtained from modified solution systems based on polyvinyl alcohol (PVA). Polyvinyl alcohol grade 098–10 was used as the starting product; glycerin grade T 94 was used as a plasticizer. The films were cast on glass, then heated in a heating cabinet at a temperature of 90 °C for 31 hours. The influence of different concentrations of PVA solutions on the barrier (vapor permeability) and physical and mechanical properties of films was studied. It was shown that, with an increase in the concentration of glycerol in PVA, the fracture resistance increased, the relative elongation noticeably decreased, and the permeability of the polymer sharply increased. The introduction of 20–30% plasticizer into PVA resulted in the production of a sufficiently elastic film, an increase in elongation at break, and also a decrease in tensile strength. The complex of studies carried out made it possible to determine the influence of modifying additives on the structural transformations of PVA compositions for the creation of new generation coatings. In the future, it is planned to continue research on this topic, in particular on optimizing the temperature-time regime of coating formation

The possibility of obtaining electrically conductive composites by applying carbon suspensions to fibrous materials by aerosol spraying and screen printing, on printing equipment, which ensures high productivity, is shown. A manufacturing technology has been developed and the electromechanical properties of layered fibrous composites based on knitwear and graphite dispersion designed for the manufacture of strain and stress sensors used in "wearable electronics", robotics and medicine have been investigated. In an experimental study, it is shown that the conductive path, that is, the length of the chains of contacting filler particles decreases with tensile deformation due to the growth of microcracks in the material. The electrical resistance of growing microcracks has much higher values than the resistance of deformable piezoresistive material. Cracks can open and close in various ways during bending, torsion, stretching and compression deformation. The electrical conductivity of fibers and filaments significantly depends on the localization of electrically conductive particles on their surface or in volume. The location of the conductive chains on the surface or in the volume of the filaments determines the dependence of the electrical properties of composites on the state of the environment (composition, temperature, humidity). Preliminary studies of filaments with electrically conductive components of various chemical nature (metals, metal salts, carbon in various allotropic forms) show that changes in temperature and humidity significantly affect the resistivity of the conductive fiber. The paper presents data on the effect of temperature and humidity on the electromechanical properties of elastic fiber composites with graphite. When stretched to 15%, the calibration coefficient GF is reduced by 2 times at 100% humidity. The different influence of air temperature in the range of 100C-700C on the deformation and strain sensitivity during cyclic deformation up to 15% and 30% has been established. The presence of two ranges of deformation sensitivity is due to the difference in the mechanisms of elongation of knitwear due to straightening and stretching of threads. Different deformation and strain sensitivity of composites in the ranges of small and significant strains, at different temperatures and humidity of the air, has been established. The strain sensitivity reaches 130, and the strain sensitivity is 12 MPa -1, which is an order of magnitude higher than the stress sensitivity of known polymer composites with various electrically conductive fillers.

The paper presents the results of synthesis the metal-composite materials based on apple pectin and divalent metal cations - Cu2+; determining the degree of esterification and the content of free carboxyl groups of the native pectin by acid-base titration, determining the degree of inclusion of the specified cation in the polysaccharide macromolecule and studying by IR spectroscopy and fungicidal activity of native pectin and copper complexes against Penicillum sp According to the results of titration, it was found that apple pectin has a high degree of esterification (DE = 50.7%) and a low content of carboxyl groups (Kc = 2.79%), which suggests its low gelling activity. It was found that the increase in salt concentration is above 0.005 g-eq/l. leads to a decrease in the proportion of the resulting water-soluble complex. The optimal concentration of CuSO4 5H2O, at which the largest mass of the water-soluble complex is formed, is 0.005 g-eq/l. According to IR spectroscopy, the degree of substitution of sodium cations for copper cations was calculated, which amounted to 18%. It was shown that the native apple pectin does not have fungicidal activity, while the copper complex based on it is able to suppress the growth of the culture already under the action of 10 µl of the substance, and with an increase in volume to 50 µl, an even more active fungicidal activity of the copper complex appears.
