The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stands for being the most serious epidemic (so far) of the 21st century. However, only a few computational studies have investigated the molecular mechanisms underlying the neutralization of the spike protein by antibodies of different classes. Hence, bioinformatic methods were employed to unravel the factors contributing to the remarkable neutralization capacity exhibited by specific antibodies. Initially, crystallographic structures of IgA monomeric / dimeric, IgG, and IgM antibodies binding with the receptor-binding domain region of the SARS-CoV-2 spike protein were retrieved. Subsequently, rigid molecular docking and molecular dynamic simulations were performed over 100 ns with explicit water solvation. Lastly, an energy decomposition was conducted to estimate the binding affinity using the last frames from molecular dynamics. The results revealed a higher binding affinity for both monomeric and dimeric forms of IgA antibodies against the spike protein. Additionally, a greater number of hydrogen bonds were observed during their interaction with the spike protein, as well as greater structural instability along the time and especially a more thermodynamically favorable interaction affinity. In this way, the research contributes a small piece to the complex puzzle of understanding the humoral immune response induced by the SARS-CoV-2 virus.

Abstract Introduction. The parameters of physiological response to drought stress are the result of a combination of slow- or fast-acting attributes. Gas exchange variables are classified as fast-acting and their level of occurrence or impact depends on the interaction between factors such as genotype and the duration, intensity, and phenological stage of stress occurrence. Objective. To identify the levels of physiological response exhibited by Solanum phureja under progressive water deficit stress. Materials and methods. The experiment was conducted between 2019 and 2020 under semi-controlled conditions at the Obonuco Research Center of the Corporación Colombiana de Investigación Agropecuaria. Four potato cultivars were planted, with half of the trial was maintained at field capacity and the other half subjected to water deficit stress by withholding irrigation for 15 days, followed by rehydration. Gas exchange variables, chlorophyll content, and photosynthetic efficiency were evaluated every three days. Results. Significant differences were observed, with maximum gas exchange values in control plants showing 16.67 µmol m-2 s-1 photosynthesis rate (A); 0.34 mol m-2 s-1 stomatal conductance (gs); 5.5 mmol m-2 s-1 transpiration (E), and under stress, 1.17 µmol m-2 s-1 (A); 0.013 mol m-2 s-1 (gs); 0.29 mmol m-2 s-1 (E). Chlorophyll content values ranged between 451.7 and 474.69 mg m-2 with and without irrigation, respectively. Conclusions. Stomatic closure was the earliest response to water deficit, and potato plants showed recovery in gas exchange values after rehydration following stress. Finally, three levels of physiological response were identified: mild, moderate, and severe stress, depending on the intensity and duration of stress, which is useful for future studies and the development of irrigation schedules.

Abstract Introduction. Heavy metal pollution is a growing problem due to human activities. Plants can remove, destroy, or transform contaminants from soil, water, and air. By using plant growth regulators and chelating agents, heavy metal toxicity can be reduced. Objective. To evaluate the effect of applying a mixture of oligogalacturonides on peroxidase activity and the contents of malondialdehyde, total protein, and chlorophylls in tomato plants (Solanum lycopersicum L.) var. Amalia subjected to high levels of heavy metals. Materials and methods. Soil contaminated with Cu, Cd, and Fe was collected from the Adalberto Vidal White Ceramic Company in Mayabeque, Cuba, in 2020. The experiment was conducted in 7 kg capacity bags using tomato plants, under semi-controlled conditions at the Instituto Nacional de Ciencias Agrícolas (INCA), with a completely randomized experimental design with each treatment having ten replicates. The treatments with the oligogalacturonides (Ogal) were soil application (30 mg kg-1); foliar spray (20 mg L-1), the combination of these application forms, and a control. Peroxidase activity and the contents of malondialdehyde, total protein, and chlorophylls were determined at 35 and 56 days after the plant’s emergence. Results. The effect of Cu, Cd, and Fe on the seedlings was attenuated by all the use of the Ogal mixture variants use, indicating that they have developed adaptation mechanisms to high metal concentrations which allows to withstand abiotic stress. Conclusions. The Ogal mixture attenuated the effect of heavy metals on peroxidase activity, malondialdehyde content, total proteins, and chlorophylls in Amalia tomato plants.

Irrigation is required to supplement rainfall to enhance the productivity of chickpea in South Africa (SA). However, the dependence on irrigation can be problematic for SA and other countries with limited natural water resources and variable rainfall. Even though access to irrigation water has been identified as one of the challenges faced when planting chickpea in the winter season in SA, irrigation management strategies for chickpea grown on soils differing in texture have not gained considerable research attention. Hence, this study aimed to assess the effects of irrigation levels on dry matter production of chickpea grown on two soils differing in soil texture under greenhouse conditions. The experiment was arranged as a 3 × 2 factorial in a completely randomized design, with 3 irrigation levels (25%, 50% and 75% of the water-holding capacity of soil (WHC)) and 2 soils differing in soil textural class (Loamy sand (LS) soil and sandy loam (SL) soil), replicated thrice. Irrigation level, soil texture and their interaction significantly affected shoot biomass (SBM) and total plant biomass (TBM). Generally, SBM, TBM and root biomass decreased correspondingly with the reduction in irrigation. The 25% WHC significantly reduced the SBM by up to 60% and TBM by up to 56% compared to the 50% and 75% WHC. The SBM and TBM were higher in SL soil than in LS soil. A significantly higher root/shoot ratio (0.45) in the LS soil than in the SL soil (0.16) indicated that the conditions of LS soil encouraged plants to allocate higher proportions of biomass into roots, possibly due to increased competition for soil resources. In conclusion, maintaining soil moisture at 50% WHC ensures better chickpea dry matter production in SL soil.

ABSTRACT Red chili pepper Capsicum annuum L. var. annuum plants are one of the fruity vegetable types that are often cultivated in riparian tropical wetlands but are constrained by water stress such as waterlogging during rainy season and drought in dry season. The aim of this research was to evaluate the growth and morpho-physiological responses of red chili pepper cultivars subjected to waterlogging and drought stress conditions. The experiment was carried out in a strip-plot design with two factors. The first factor was three water stress treatments, namely control (field capacity), waterlogging, and drought. The second factor was six cultivars of Indonesian red chili pepper. The findings indicated that both waterlogging and drought stress had a detrimental impact on the reduction of the growth parameters of red chili pepper such as root, shoot and total dry weight. Chili pepper defended its root weights in response to drought stress (0.653 g plant-1) whereas it preserved shoot weight in response to waterlogging (0.913 g plant-1). In the morphological characters, chili pepper exhibited an increase in specific leaf area expansion in response to both waterlogging (150.82 cm2) and drought (188.82 cm2) compared to control (140.91 cm2), but decreased specific leaf weight during stresses and recovered after 7 d in waterlogging. Leaf chlorophyll content (SPAD) and leaf relative water content (LRWC), as physiological characteristics, also experienced a decline during exposure to both waterlogging and drought during 8 d; yet, SPAD and LRWC able to recover completely at 7 d after waterlogging and drought treatment were terminated.

Resumo Objetivo: Analisar o efeito da ativação por meio de exercícios de força e pliométricos bilaterais ou unilaterais no desempenho do salto horizontal. Metodologia: O estudo envolveu 15 jogadores de futebol masculinos altamente treinados (idade, 24.7 ± 3.1 anos; altura, 181.2 ± 4.7 cm; peso, 79.7 ± 3.4 kg) da mesma equipe competindo na liga nacional. Sua rotina de treinamento regular consistia em 4 sessões e 1 jogo competitivo por semana. Os participantes realizaram 1 protocolo de controle (CON) e 3 protocolos de ativação seguindo um desenho contrabalanceado com base em exercícios específicos de futebol (SIN), exercícios de força e pliométricos bilaterais (BIL) e unilaterais (UNI). Após cada protocolo, os jogadores foram submetidos ao teste de salto horizontal (HZB). Resultados: A ANOVA de medidas repetidas revelou efeitos positivos significativos no HZB para os protocolos SIN (p<0.01; diff = 2.95(2.00) %), BIL (p<0.01; diff = 3.22(2.61) %) e UNI (p<0.01; diff = 6.80(3.40) %) em comparação com CON. Além disso, o HZB foi significativamente maior após o protocolo UNI do que após SIN (p<0.01; diff = 3.74(2.62) %) e BIL (p<0.01; diff = 3.47(1.94) %). A análise de resposta individual refletiu efeitos positivos no HZB para SIN, BIL e UNI em comparação com CON, enquanto 89 % dos jogadores mostraram melhor desempenho de HZB após UNI do que após BIL. Conclusões: A ativação incorporando estímulos de força e pliométricos unilaterais tem um efeito positivo maior na capacidade de salto horizontal do que a ativação envolvendo exercícios gerais, específicos do futebol e bilaterais.

ABSTRACT: The seedbed phase is decisive in the use of quality seedlings for transplanting. This research aimed to evaluate the differentiated vegetative response of tomato cultivars (Solanum lycopersicum L.) to two substrates under tray conditions. The experiment was carried out at the University of Pinar del Río, Cuba. The cultivars 'Celeste', 'Desquite', 'Grandioso' and 'Radiante' were used in a completely randomized design with factorial arrangement (factors: substrate and cultivar). The substrates were made from Fersialitic soil, organic materials (humus or peat) and rice husks. Sowing was carried out in trays with 40 alveoli (tubes), with a capacity for 70 g of substrate each. The substrates used guaranteed adequate morphophysiological development of tomato seedlings, regardless of the cultivar evaluated, although 'Desquite' presented the lowest absolute growth rate. With the use of the substrate based on soil, humus and rice husk, the number of seedlings useful for transplanting increased by 5%, which guarantees a reduction in the number of trays and volume of substrate used in this phase of crop.

RESUMEN: La fase de semillero es determinante en la utilización de plántulas con calidad para el trasplante. Esta investigación tuvo como objetivo evaluar la respuesta vegetativa diferenciada de cultivares de tomate (Solanum lycopersicum L.) a dos sustratos en condiciones de bandejas. El experimento se ejecutó en la Universidad de Pinar del Río, Cuba. Se utilizaron los cultivares ‘Celeste’, ‘Desquite’, ‘Grandioso’ y ‘Radiante’, en un diseño completamente al azar con arreglo factorial (factores: sustrato y cultivar). Los sustratos se elaboraron a base de suelo Fersialítico, materiales orgánicos (humus o turba) y cascarrilla de arroz. La siembra se realizó en bandejas de 40 alvéolos (tubetes), con capacidad para 70 g de sustrato cada uno. Los sustratos empleados garantizaron un adecuado desarrollo morfofisiológico de las plántulas de tomate, independientemente del cultivar evaluado, aunque ‘Desquite’ presentó la menor tasa absoluta de crecimiento. Con el empleo del sustrato a base de suelo, humus y cascarilla de arroz, se incrementó en 5% las plántulas útiles para el trasplante, lo que garantiza una reducción en el número de bandejas y volumen de sustrato empleados en esta fase del cultivo.

Abstract Pastures is important for livestock production, are source of food mainly for ruminant livestock. The study was conducted in grasslands of the highlands of Puno, Peru, at an altitude of 3818 masl. The objective was to determine the effect of revegetation with two native grasses: Festuca dolichophylla Presl "chilligua" (Fedo) and Poa gilgiana Pilger "K'achu" (Pogi) in the recovery of degraded pastures with the addition of sheep manure as a source of organic matter (OM), conducted under a split-plot design whose study factors were 2 native species, 2 fertilization factors with and without the addition of sheep feces and urine (OM), in 3 blocks; The results indicate that the highest growth and biomass yield was for Fedo, probably due to its adaptive capacity, the green matter yield of Fedo and Pogi was higher in the treatment with the addition of OM, the incorporation of manure to the pasture had a positive influence on the recovery of the pasture, on the other hand Fedo had a greater height than Pogi; Likewise, the seed production of the treatments with added OM was higher than the treatments without OM; the protein content with addition of OM was higher in both species and the NDF was higher in the species without addition of OM; the application of OM favored the growth and nutritive value of the species. It was concluded that revegetation and incorporation of sheep manure had a favorable effect on the recovery and nutritional quality of the pasture.

INTRODUCTION: Clinical utility is an important attribute in selecting an assessment tool. The study aimed to determine the perceptions of South African occupational therapists of the clinical utility of Modular Arrangement of Predetermined Time Standards (MODAPTS) work samples when assessing a client's work ability. The research objectives were to determine whether MODAPTS is perceived to be credible, practical, useful, and easy to use. METHODOLOGY: A quantitative, cross-sectional, descriptive research design was used. Non-probability sampling with elements of voluntary response- and snowball sampling was used to recruit respondents. An electronic questionnaire was developed using Qualtrics, which was distributed electronically via the Occupational Therapy Association of South Africa, WhatsApp and Telegram. RESULTS: Data were based on 52 completed questionnaires, analysed through descriptive statistics MODAPTS was perceived as practical, useful, credible, and asy to use in practice. Main barriers to the use of MODAPTS included the timeliness of developing work samples, lack of MODAPTS training, and having other more useful and reliable assessment tools. Experienced occupational therapists used MODAPTS more often than inexperienced occupational therapists. CONCLUSION: Clinical utility of work samples developed using MODAPTS has been confirmed. This supports the use of work samples developed using MODAPTS as part of work assessments as a cost-effective, practical tool. IMPLICATIONS FOR PRACTICE: • Development of contextually relevant work samples. •Use of MODAPTS work samples as an outcome measure during intervention. • Application during rehabilitation goal setting. • Cost effective application of MODAPTS work samples in a variety of settings.

ABSTRACT To favor the process of comprehension of texts in students with autism spectrum disorder, it is necessary to start from the conception that every individual has the capacity to learn and develop in different fields, it is enough that the appropriate resources are used. In response to this problem, research is carried out that aims to argue particular ideas and points of view about the peculiar nature of the text comprehension process in the education of students with autism spectrum disorder, from a cultural-historical position, which claims of an organization that takes into account social and instrumental mediation. In its development, theoretical-level methods such as analytical-synthetic, induction-deduction, hypothetical-deductive, observation and interview were taken into account, as well as those corresponding to descriptive and inferential statistics that allowed collecting, interpreting and process the information related to the subject. It is also intended to assess the process of text comprehension from a socio-communicative perspective that favors the social inclusion of students with autism spectrum disorder.

Resumo Se por um lado, doenças pancreáticas comuns, tais como pancreatite aguda (PA), pancreatite crónica (PC) e cancro pancreático (CP), podem ter um grande impacto na normal fisiologia pancreática e contribuir para desnutrição, por outro lado, uma abordagem nutricional adequada nos doentes com essas patologias pode influenciar significativamente o seu prognóstico. Em doentes com PA, os objetivos do suporte nutricional são a prevenção da desnutrição, a correção de um balanço negativo de nitrogénio, a redução da inflamação, e a evicção de outcomes desfavoráveis, como desenvolvimento de complicações locais ou sistémicas ou morte. A desnutrição é comum em doentes com PC, sendo frequentemente umamanifestaçãotardiadadoença, da qual resulta uma diminuição da capacidade funcional e da qualidade de vida, bem como um aumento significativo do risco de doença óssea, complicações pós-operatórias, hospitalizações e morte. A desnutrição associada ao CP é também habitual e é atualmente reconhecido que um suporte nutricional precoce pode influenciar favoravelmente a sobrevida, não só por aumentar a tolerância e resposta aos tratamentos, mas também por melhorar a qualidade de vida e diminuir as complicações pós-operatórias. O objetivo da presente revisão é salientar o papel da nutrição e propor uma abordagem nutricional sistematizada nos doentes com PA, PC e CP.

Abstract While common pancreatic diseases, such as acute pancreatitis (AP), chronic pancreatitis (CP), and pancreatic cancer (PC), may greatly impact the normal pancreatic physiology and contribute to malnutrition, the adequate nutritional approach when those conditions are present significantly influences patients’ prognosis. In patients with AP, the goals of nutritional care are to prevent malnutrition, correct a negative nitrogen balance, reduce inflammation, and improve outcomes such as local and systemic complications and mortality. Malnutrition in patients with CP is common but often a late manifestation of the disease, leading to decreased functional capacity and quality of life and increased risk of developing significant osteopathy, postoperative complications, hospitalization, and mortality. Cancer-related malnutrition is common in patients with PC, and it is now well recognized that early nutritional support can favorably impact survival, not only by increasing tolerance and response to disease treatments but also by improving quality of life and decreasing postoperative complications. The aim of this review was to emphasize the role of nutrition and to propose a systematic nutritional approach in patients with AP, CP, and PC.

ABSTRACT: Inclusion of rural youth is of great importance to facilitate nutritional security and make the food chain more sustainable. A positive attitude is necessary for active participation in agricultural activities. This case study was an attempt to check the attitude of rural youth regarding sustainable farming and its contributing factors. The study was carried out in the Punjab province of Pakistan and a transverse research design was used for this quantitative study. An interview schedule was used for getting the face-to-face response of rural youth. To make the unknown population of rural youth in Punjab, the Fisher formula was used and a sample of 413 was selected from purposely selected three districts of Punjab. After recording data, Statistical Package for Social Sciences (SPSS) was used to analyze the data. Descriptive Statistics was used to explain the response of rural youth for the decision on the base of data. Only 53 young farmers said that they have never been part of the formal education system and maximum number of farmers was close to 24 years of age or more than that. Rural youth of Punjab is lacking in non-formal education for acquiring or maintaining their skills & interests. Unemployment and having limited farm income are the biggest challenges that rural youth is facing. Rural youth show a strong inclination towards opting for sustainable farming alongside the availability of a supportive network. Regarding to learning capacities rural youth is lacking related to knowledge, communication means, novel approaches and in promoting sustainable farming initiatives. To achieve the goal of sustainability in changing environment, rural youth must have access to continuous training, communication sources, membership, or association with organizations with novel ideas covering all the changes happening in the farming business.

Uma atitude positiva é necessária para a participação ativa nas atividades agrícolas. Este estudo de caso foi uma tentativa de verificar a atitude da juventude rural em relação à agricultura sustentável e seus fatores contribuintes. O trabalho foi realizado na província de Punjab, no Paquistão, e um projeto de pesquisa transversal foi usado para este estudo quantitativo. Um roteiro de entrevista foi usado para obter a resposta face a face da juventude rural. Para determinar a população desconhecida de jovens rurais em Punjab, a fórmula de Fisher foi usada e uma amostra de 413 foi selecionada de três distritos selecionados de Punjab. Após o registro dos dados, foi utilizado o Statistical Package for the Social Sciences (SPSS) para análise dos dados. A Estatística Descritiva foi utilizada para explicar a resposta dos jovens rurais para a decisão sobre a base de dados. Apenas 53 jovens agricultores disseram que nunca fizeram parte do sistema de educação formal e o número máximo de agricultores foi próximo aos 24 anos de idade ou mais. A juventude rural de Punjab carece de educação não formal para adquirir ou manter suas habilidades e interesses. Atualmente, o desemprego e a renda agrícola limitada são os maiores desafios que a juventude rural enfrenta. A juventude rural mostra uma forte inclinação para optar pela agricultura sustentável, juntamente com a disponibilidade de uma rede de apoio. No que diz respeito às capacidades de aprendizagem, a juventude rural carece de conhecimentos relacionados, meios de comunicação, novas abordagens e, até certo ponto, participação em organizações que promovem iniciativas de agricultura sustentável. Para alcançar a meta de sustentabilidade no ambiente em mudança, a juventude rural deve ter acesso a treinamento contínuo, fontes de comunicação, associação ou associação com organizações com ideias inovadoras que cubram todas as mudanças que ocorrem no negócio agrícola.

ABSTRACT This study aimed to evaluate the use of decision trees to select sows based on the production parameters of parity order (PO) 1 sows from a commercial herd. Data were collected at a piglet production unit with a capacity of housing 5,500 sows in collective pens. Piglet production and sow culling information was collected from PO1 and PO2 sows. The period from January 2017 to March 2020 was analyzed. The correlation analysis was used to identify the influence of the production parameters on sow culling after exploring the database using the graphical analysis and descriptive statistics. The ANOVA was applied to evaluate differences in the response variables between culled and unculled sows. Two models were proposed using the decision tree method: model 1 referred to sow culling, and model 2 comprised the total number of liveborn piglets (TBA). The calculated value was close to 0, although the correlations of the production parameters with culling were statistically significant. The mean number of weaned piglets was higher for unculled sows in PO1 (p < 0.05). The number of weaned piglets, total number of liveborn piglets, and weaning-service interval did not differ in the unculled and culled sows in PO2 (p > 0.05). Using a confusion matrix as a metric tool, the decision tree method used in this study provided consistent results for this database, indicating its possible use for decision-making in sow selection.
