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.

Computational predictive approaches present themselves as an attractive alternative in the search for new compounds that may present toxic or growth regulatory activity in Aedes aegypti. Aspergillus species is a producer of secondary metabolites with diverse biological activities. In this study, it was possible to evaluate the pharmacokinetic and toxicological properties in silico, as well as the prediction of the insecticidal biological activities of the juvenile hormone of natural substances produced by the genus Aspergillus. Initially, 187 molecules were cataloged from various species of Aspergillus spp., and only seven molecules of indole alkaloids were found to exhibit a toxic dose 50% (TD50) after conducting toxicity predictions. The molecular dynamic simulation trajectories were utilized to study parameters such as root mean square deviation, root mean square fluctuation, radius of gyration and intermolecular hydrogen bond to understand the behavior and stability of proposed compounds in the binding pocket of the target protein. The N-β-acetyltryptamine molecule showed a binding affinity value of –8.100 ± 0.200 kcal mol-1, which classifies the compound as a potential insecticidal agent against the Aedes aegypti vector. silico Initially 18 spp spp. 50 TD50 TD (TD50 predictions deviation fluctuation protein Nβacetyltryptamine N β acetyltryptamine 8100 8 100 –8.10 0200 0 200 0.20 mol1, mol1 mol 1, 1 mol-1 vector 5 TD5 (TD5 810 10 –8.1 020 20 0.2 mol- (TD 81 –8. 02 2 0. –8 –

RESUMO Este estudo foca no desempenho de vacas para produção de carne, criadas nos pântanos do Paraguai, examinando cinco genótipos bovinos; Brahman, Brangus, Nelore, bem como duas raças locais em risco de extinção. O principal objetivo é identificar e classificar variáveis fenotípicas que incluem variáveis sanguíneas, clínicas, de pelagem e saúde, demonstrando ligação causal com o peso vivo das vacas analisadas. Inicialmente, foram identificadas correlações elevadas entre diferentes variáveis incluídas neste estudo, e, então, utilizando técnicas avançadas de aprendizado de máquina e a aplicação de explicações aditivas de Shapley (SHAP), foi proporcionado um entendimento mais profundo dos fatores fortemente associados à adaptabilidade nestes ambientes, e, portanto, o respectivo desempenho zootécnico. A associação entre o componente genotípico bovino ligado à estação do ano mostrou ser o fator influente mais predominante sobre o peso vivo bovino. Variáveis como comprimento do pelo, hematócrito, fosfatase, fósforo, creatina phosphokinase, creatinina, proteína, cortisol, cálcio e a presença de endoparasitas foram destacadas, demonstrando sua importância hierárquica para a seleção animal.

ABSTRACT This study focuses on the performance of cows for meat production raised in the wetlands of Paraguay, examining five cattle genotypes: Brahman, Brangus, and Nelore, as well as two local breeds at risk of extinction. The main objective is to identify and rank phenotypic variables, including blood, clinical, hair, and health variables, demonstrating causal linkage with the live weight of the cows analyzed. Initially, high correlations were identified between different variables included in this study; then, using advanced Machine learning (ML) techniques and the application of Shapley additive explanations (SHAP), a deeper understanding was provided of the factors strongly associated with adaptability in these environments, and, therefore, the respective zootechnical performance. The association between cattle genotypic components linked with the season of the year proved to be the most influential factor on cattle live weight. Variables such as hair length, hematocrit, phosphatase, phosphorus, creatine phosphokinase, creatinine, protein, cortisol, calcium, and the presence of endoparasites were highlighted, demonstrating their hierarchical importance for animal selection. ML models are effective tools for establishing hierarchies of relevance in complex phenotypic multivariable, which is crucial in breeding programs for different zootechnical species and in special and specific environments like wetlands.

ABSTRACT The development of aquaculture through the cultivation of what are considered unconventional species is an option with the potential to solve the problem of food scarcity. The aim of the present study was to evaluate the zootechnical performance of juvenile Pomacea haustrum fed different commercial diets, and subjected to different levels of salinity. After seven P. haustrum spawn had hatched in the laboratory, the juveniles were randomly selected and transferred to the rearing containers. Two different commercial diets were offered: rabbit feed with a high proportion of ingredients rich in crude vegetable protein (VP), and dog food containing balanced levels of ingredients rich in crude vegetable and animal protein (MP). The selected juveniles were randomly stocked at different salinities (0, 2 and 4 parts per thousand - ppt). The experiment lasted 65 days. Twenty-one hours after the start of the experiment, 100% of the individuals reared at a salinity of 4 ppt had died. There was a significant difference (p ≤ 0.05) between the results for zootechnical performance (average final weight, weight gain, average final growth, specific growth rate, protein efficiency and apparent feed conversion) for animals reared in fresh water or at a salinity of 2 ppt, regardless of the type of diet. The origin of the protein in the diet had no significant effect on the zootechnical performance of the individuals; however, the salinity of the water impaired development of the animals in direct proportion to its concentration. scarcity P laboratory containers offered VP, VP , (VP) MP.

Brazilian Savanna biodiversity is abundant in native fruits with nutritional and sensory properties with potential technological applications. However, the information available regarding the proprieties of Brazilian native fruits is still limited. This study aimed to analyze the metabolic profile of Brosimum gaudichaudii fruits (BGF) using metabolomics approaches, besides its physicochemical and nutritional proprieties. BGF exhibited protein content at least two times higher than other native fruits. Fifty-five metabolites were identified by the metabolomics approaches, mainly fatty acids (n = 22), carbohydrates (n = 13), organic acids (n = 6), and polyphenols (n = 5). The most abundant constituents were D-fructose (42.97%) for sugars, L-asparagine (6.47%) for amino acids, succinic acid (44.11%) for organic acids, and linolenic acid (3.04%) for fatty acids. Highlighted phytochemicals included chlorogenic acid, α-amyrin, and γ-tocopherol. Additionally, this study revealed that BGF is a good source of vitamin C and dietary fiber and an excellent source of vitamin A. Future studies providing nutritional information and suggesting consumption methods and potential industrial applications are essential to familiarize consumers with these foods. Additionally, clarifying the appropriate planting and harvesting seasons can revive traditional practices, especially for native fruits like BGF.

Seaweeds have been explored by humans for thousands of years as a source of chemical compounds. This study describes the content of minerals, ash, carbohydrates, protein, lipids, and main metabolites of dichloromethane / methanol extracts of the seaweed Ulva lactuca, Padina gymnospora, Palisada perforata and Gelidiella acerosa from sandstone reefs on the Brazilian tropical coast (Pernambuco, Northeastern of Brazil). The content (% dry weight) of carbohydrates ranged from 14.35-48.52, proteins 7.49-14.98, total lipids 0.40-8.92, and ash 18.51-37.02. The concentration (mg kg dry algae−1) of Ca (900-3468), Mg (1655-4902), K (810-1707), Na (1062-4580), Mn (19-4462), and Cu (3.6-6.4) were maximum in Palisada and minimum in Padina. In turn, the lowest and highest contents (mg kg dry algae−1) of Fe (100-2312), Zn (18-43), and Cr (0.08-0.93) were recorded in Gelidiella and Ulva, respectively. Neophytadiene was the major compound. Phytol and palmitic acid were found in all seaweeds, although in low quantities. Palisada had the highest contents (% dry weight) of metabolites (neophytadiene: 23.89, phytol: 8.29; palmitic acid: 8.32), while Ulva had the lowest, except phytone, which was present only in this species. Our findings highlight the potential of these macroalgae from the coastal reefs as a source of chemical compounds. compounds minerals protein lactuca gymnospora Pernambuco, Pernambuco (Pernambuco Brazil.

The in silico study aimed to suggest phytochemicals from Commiphora leptophloeos leaves essential oil as therapies against coronavirus disease (COVID-19) (or severe acute respiratory syndrome coronavirus 2, SARS-CoV-2). For that, we used molecular docking (MD), absorption, distribution, metabolism, excretion, and toxicity (ADMET) parameters, and pharmacokinetic analysis. MD showed the presence of hydrophobic and hydrogen bonds for nine compounds. β-Selinene and bicyclogermacrene showed the best interaction values with the protein Mpro (ID: 6Y2F) (-5.9) and chimeric receptor complexed with its receptor human ACE2 (ID: 6VW1) (-6.1 and -5.5) proteins, as well as low gastrointestinal and high epithelial absorptions, medium permeability for Caco-2 cells and high epithelial permeability, low oral excretion, and were inhibitors of CYP2C19 and CYP2C9 enzymes. On the other hand, both were not permeable to the blood-brain barrier and inhibitors or substrates for glycoprotein-D, and showed carcinogenic potential, but only β-selinene was considered mutagenic. Although little bioavailable, both presented aspects structurally adequate, being compounds with moderate synthesis difficulty. Therefore, more analyses are necessary to evaluate the mechanism of action and unsatisfactory parameters foreseen in bioinformatic assays. COVID19 COVID 19 (COVID-19 2 SARSCoV2.

ABSTRACT Purpose: To characterize the extracellular vesicle protein cargo in the aqueous humor and plasma of patients with ocular toxoplasmosis. Methods: Aqueous humor and plasma were collected from six patients with active ocular toxoplasmosis and six patients with cataract. Extracellular vesicles were isolated, and western blotting and mass spectrometry were performed for protein analysis. Results: All plasma samples from patients with ocular toxoplasmosis and cataract were positive for the tetraspanins CD63 and TSG101. However, the aqueous humor from patients with ocular toxoplasmosis was positive only for CD63. Sixty-seven new unreported proteins were identified in the aqueous humor and plasma of patients with the ocular toxoplasmosis and cataract. Of the 67 proteins, 10 and 7 were found only in the cataract and ocular toxoplasmosis groups, respectively. In general, these proteins were involved in immune system activation and retina homeostasis and were related to infections and retina-associated diseases. Conclusion: The distinct protein signatures between ocular toxoplasmosis and cataract may be helpful in the differential diagnosis of ocular toxoplasmosis. However, more studies are needed to better understand the role of these proteins in the pathogenesis of ocular toxoplasmosis.

ABSTRACT Purpose: The epithelial–mesenchymal transition of human lens epithelial cells plays a role in posterior capsule opacification, a fibrotic process that leads to a common type of cataract. Hyaluronic acid has been implicated in this fibrosis. Studies have investigated the role of transforming growth factor (TGF)-β2 in epithelial–mesenchymal transition. However, the role of TGF-β2 in hyaluronic acid-mediated fibrosis of lens epithelial cell remains unknown. We here examined the role of TGF-β2 in the hyaluronic acid-mediated epithelial–mesenchymal transition of lens epithelial cells. Methods: Cultured human lens epithelial cells (HLEB3) were infected with CD44-siRNA by using the Lipofectamine 3000 transfection reagent. The CCK-8 kit was used to measure cell viability, and the scratch assay was used to determine cell migration. Cell oxidative stress was analyzed in a dichloro-dihydro-fluorescein diacetate assay and by using a flow cytometer. The TGF-β2 level in HLEB3 cells was examined through immunohistochemical staining. The TGF-β2 protein level was determined through western blotting. mRNA expression levels were determined through quantitative real-time polymerase chain reaction. Results: Treatment with hyaluronic acid (1.0 μM, 24 h) increased the epithelial–mesenchymal transition of HLEB3 cells. The increase in TGF-β2 levels corresponded to an increase in CD44 levels in the culture medium. However, blocking the CD44 function significantly reduced the TGF-β2-mediated epithelial–mesenchymal transition response of HLEB3 cells. Conclusions: Our study showed that both CD44 and TGF-β2 are critical contributors to the hyaluronic acid-mediated epithelial-mesenchymal transition of lens epithelial cells, and that TGF-β2 in epithelial-mesenchymal transition is regulated by CD44. These results suggest that CD44 could be used as a target for preventing hyaluronic acid-induced posterior capsule opacification. Our findings suggest that CD44/TGF-β2 is crucial for the hyaluronic acid-induced epithelial-mesenchymal transition of lens epithelial cells.

The coronavirus disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has had a profound impact on global health and socio-economic conditions. To date, various vaccines have been administered worldwide in an effort to curb the spread of the virus. Despite vaccination efforts, there have been complications. Existing antiviral drugs have shown limited effectiveness, prompting the use of computational methods to understand the dynamics of the virus and develop suitable treatments. The current study focuses on using biocompatible para-sulfonato-calix[4]arenes to dock against two key proteins of SARS-CoV-2, namely ribonucleic acid (RNA)-dependent RNA polymerase, and helicase. Docking results indicate a strong binding affinity of these compounds to the target proteins, with higher scores compared to commonly used medications. Molecular dynamics (MD) simulation validates the docking results, showing stable protein-ligand complexes over time. The compounds are also screened for absorption, distribution, metabolism, and excretion properties and toxicity, suggesting their potential as lead candidates for inhibiting the virus’s key proteins. However, further in vivo and in vitro studies are recommended to confirm these findings.

Microparticulated whey protein can be used as a fat substitute in foods to enhance their nutritional value and improve their sensory and rheological characteristics. Microparticulation denatures whey proteins through heat treatment, followed by shear rate control to determine the aggregate sizes formed. The processing method used during microparticulation can modify the protein denaturation rate, which may enable the application of new proteins. This study sought to develop a methodology for quantifying whey protein fractions in commercial samples before and after microparticulation at different concentrations and physical states. The developed methodology proved to be applicable because of its selectivity, quantification, detection limits, and precision. The analyzed samples exhibited a higher denaturation rate for β-lactoglobulin than α-lactoalbumin; the denaturation rate varied among samples due to differences in the microparticulation process. characteristics treatment formed states selectivity quantification limits precision βlactoglobulin β lactoglobulin αlactoalbumin α lactoalbumin α-lactoalbumin process

RESUMO: Este estudo explorou o uso exclusivo do ultrassom (US) para extrair proteínas das espinhas dorsais da carpa-capim (Ctenopharyngodon idella) em baixas temperaturas e examinou seu impacto na hidrofobicidade, solubilidade, perfil eletroforético e níveis de sulfidrilas. As espinhas dorsais foram tratadas com 35 e 130 kHz por 20, 30 e 40 minutos a 14 ºC, resultando em duas frações de proteínas: sólida (TPS) e líquida (TPL). O US aumentou o rendimento em comparação com a fração não sonificada. TPL (35 kHz) apresentou uma redução de 16% nos níveis totais e livres de sulfidrila e um aumento de 25% na hidrofobicidade. O US induziu alterações na conformação proteica e na intensidade das bandas, especialmente entre 25 e 100 kDa para TPL a 130 kHz e abaixo de 30 kDa para TPS a 35 kHz. Este estudo demonstrou a eficácia do US na extração e na modificação de algumas propriedades das proteínas de subprodutos de peixe, facilitando assim seu emprego no desenvolvimento de produtos alimentícios inovadores.

ABSTRACT: This study explored the use only of ultrasound (US) for extracting proteins from grass carp (Ctenopharyngodon idella) backbones at low temperature and examined its impact on hydrophobicity, solubility, electrophoretic profile, and sulfhydryl levels. Backbones were treated with 35 and 130 kHz for 20, 30, and 40 minutes at 14 ºC, resulting in two protein fractions: solid (TPS) and liquid (TPL). US increased yield compared to the non-sonicated fraction. TPL (35 kHz) exhibited a 16% reduction in total and free sulfhydryl levels and a 25% increase in hydrophobicity. US induced protein conformation and band intensity alterations, particularly between 25 to 100 kDa for TPL at 130 kHz and below 30 kDa for TPS at 35 kHz. This study demonstrated the efficacy of US for protein extraction from fish by-products and its capacity to modify protein characteristics, facilitating the development of innovative food products.

ABSTRACT Beans are a vital component of the human diet, being able to supply a large part of the daily protein requirements of individuals, in addition to containing considerable amounts of iron, calcium, vitamins, carbohydrates, fiber, and lysine. Controlled germination is an accessible and effective technique that aims to improve the nutritional, functional, and sensory qualities of seeds intended for food consumption. This study aimed to characterize fresh and germinated beans of Phaseolus vulgaris (carioca, branco, preto, gordo varieties) and Vigna unguiculata (cowpea). The germination process was conducted in trays containing the sand substrate (350 g) in the environmental conditions of the laboratory. The fresh and germinated beans were evaluated for physicochemical variables in triplicate. The germination process increased moisture content, water activity, ash, pH, soluble alcohol acidity, proteins, ascorbic acid, phenols, tannins, flavonoids, anthocyanins, and carotenoids. On the other hand, there was a reduction in the content of lipids, starch, and total sugars in bean seeds. With the increase in bioactive compounds, it was found that the germination process is an excellent method for increasing the nutritional quality of beans. diet individuals iron calcium vitamins carbohydrates fiber lysine functional consumption carioca, carioca (carioca branco preto varieties cowpea. cowpea .

RESUMO O feijão é um importante componente da dieta humana, sendo capaz de suprir grande parte das necessidades proteicas diárias dos indivíduos, além de conter quantidades consideráveis de ferro, cálcio, vitaminas, carboidratos, fibras e lisina. A germinação controlada é uma técnica acessível e eficaz que visa melhorar as qualidades nutricionais, funcionais e sensoriais de sementes destinadas ao consumo alimentar. O objetivo deste estudo foi caracterizar feijão Phaseolus vulgaris das variedades carioca, branco, preto, gordo e feijão-caupi (Vigna unguiculata) in natura e germinado. O processo de germinação foi realizado em bandejas contendo substrato areia (350 g), em condições ambientais de laboratório. Em seguida, os grãos in natura e germinados foram avaliados quanto às variáveis físico-químicas em triplicata.

ABSTRACT Plant growth regulators play an essential role in plants’ biochemical processes. In this study, foliar spray was applied using three growth regulators, gibberellic acid (GA3), naphthalene acetic acid (NAA), and 6-benzyl amino purine (BAP), to investigate their effects on wheat (Triticum aestivum L.) ‘Giza-171’ yield traits and grain biochemical constituents, including sugars, carbohydrates and protein. The assessed growth regulators (GA3, NAA, and BAP) were applied at 100 and 150 mg L-1 concentrations. The results indicated significant improvements in wheat grain yield and 1000-grain weight, which increased by 15.40% and 24.78%, respectively, using GA3 at 150 and 100 mg L-1. In addition, the highest contents of protein and carbohydrates were observed with samples treated by the foliar application of NAA at 150 mg L-1 and BAP at 100 mg L-1, respectively. The fat content in wheat grains increased by 1.97% and 2.73% with foliar spray with 150 mg L-1 NAA and 100 mg L-1 BAP, respectively. The lipid profile showed cis-linoleic acid was the primary fatty acid, followed by palmitic acid; the content of linoleic acid slightly increased with GA3 treatment to 50.42%, while palmitic acid significantly increased with 100 mg L-1 NAA. The total saturated and unsaturated fatty acids recorded 33.64% and 66.30%, respectively; the 150 mg L-1 NAA treatment had the lowest saturated fatty acid content. The SDS-PAGE profiles showed that growth regulators significantly enhanced the wheat protein where new bands appeared, especially in 100 mg L-1 GA3 and 100 mg L-1 BAP treatments. The applied growth regulators improved wheat yield, contents of some compounds, and nutritional value.

ABSTRACT In response to global concerns over food scarcity, the sweet potato (Ipomoea batatas (L.) Lam) has emerged as a promising alternative due to its rich composition of carbohydrates (starch), protein, fiber, vitamins, and minerals. This study aims to assess the physicochemical characteristics and nutritional content of different sweet potato landraces cultivated in Yucatan, Mexico. The study involved the evaluation of eight landraces of sweet potato cultivated in traditional farming systems, assessing both physicochemical and proximate composition variables, and determining the starch yield, starch color, protein content, swelling degree, and starch solubility index. The sweet potato landraces showed values ranging from acidic to slightly neutral pH (6-6.4). The yellow sweet potato II, purple sweet potato, and pink sweet potato landraces displayed high levels of total soluble solids with a range of 12.5 to 14.33 °Brix. Significant differences were observed in both peel and root pulp coloration. The pink, yellow, purple I, mamey, yellow II, and purple sweet potato landraces, presented elevated percentages of carbohydrates (85.0% to 89.0%), fats (1.1% to 1.5%), protein (3.5% to 5.1%), fiber (4.0% to 5.0%), and ash (3.5% to 4.0%). The mamey sweet potato and pink sweet potato landraces showed higher starch yields. Swelling power and starch solubility index peaked at a temperature of 90 °C. These results highlight the significance of sweet potato landraces cultivated in Yucatan as a valuable genetic resource with nutritional potential, which can be included in the diet of people, genetic improvement and species conservation programs.
