ABSTRACT Moringa oleifera Lam. is an arboreal forest species of great economic potential, adapted to the climatic conditions of the Brazilian semi-arid region, whose multiplication is mainly by seeds. Rapid viability and vigor tests help in the choice of lots. Thus, the objective of this study was to assess the efficiency of the pH of exudate and primary root protrusion tests in the evaluation of viability and vigor, respectively. Two seed lots were initially evaluated for moisture content, germination, first count, germination speed index, seedling length, seedling dry mass and electrical conductivity. For the pH of exudate test, phenolphthalein (1%) and sodium carbonate (2 and 4 g L-1) solutions were prepared, with three soaking periods (1, 3 and 5 h) and three temperatures (25, 30 and 35 °C). Exudate solution in strong to light pink color indicated viable seeds, whereas very light pink color to colorless indicated non-viable seeds. The primary root protrusion test was performed under 25, 30 and 35 °C, evaluating the primary root protrusion of at least 2 mm, every 12 h until 196 h. The experimental design was completely randomized, with four replicates. pH of exudate test with 1 h of soaking at 25 or 30 °C with 2 g L-1 sodium carbonate solution was promising, but further studies are needed before it is indicated as routine use for the species. Primary root protrusion test is efficient and can be conducted at 35 °C with evaluation after 48 h.

ABSTRACT Biochar can promote crop production and soil quality. However, its characteristics depend on the waste used in its production and its effects may vary according to the species being cultivated and the management adopted. The aim of this study was to evaluate the application of biochar from animal waste on soil quality and the agronomic characteristics of the cowpea. An experiment was set up to test three types of biochar (bovine-BB, swine-SB and poultry-BP), with added fertiliser (BBF, SBF and BPF) and two control treatments, including the addition of calcium magnesium oxide (CT) and calcium magnesium oxide with fertiliser (CTF), giving a total of eight treatments with four replications. There was a respective increase of up to 102.94%, 1048%, 1560% and 360.22% in stem diameter, number of pods, number of grains per pod and stem dry matter from adding the biochar. The poultry biochar increased each of the above parameters even with no added fertiliser. There was no difference in basal soil respiration or β-glucosidase enzyme activity, whereas organic carbon (TOC), total nitrogen (TN), microbial carbon and soil labile carbon were greater with biochar. BBF gave the highest TOC content (24.40 g kg-1), while BP and BPF increased TN by around 61%. The application of biochar + fertiliser contributed to an average reduction of 56% in the soil metabolic quotient. Poultry biochar favoured both the agronomic characteristics of the cowpea and soil quality, while bovine biochar showed more marked results with the addition of fertiliser.

Fruits of Schinus terebinthifolia Raddi were investigated. A fast and efficient method for the simultaneous determination of 11 polyphenolic substances by high performance liquid chromatography-diode array detector (HPLC-DAD) was applied. Limits of quantification ranged between 0.78 and 3.14 mg L-1. High concentrations of kaempferol were found. An exploratory evaluation was performed using principal component analysis (PCA) for fruit origin differentiation. Total phenolic content (TPC) ranged from 274 to 517 mg GAE 100 g-1; total flavonoid content (TFC) ranged from 101 to 283 mg QE 100 g-1. In vitro analyses showed that antioxidant capacity with 2,2-diphenyl-1-picrylhydrazyl (DPPH) ranged from 1.7 to 7 µM DPPH 100 g-1. The bacteriostatic and bactericidal effect were also evaluated against: Bacillus subtilis, B. cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella choleraesuis, Candida albicans and C. glabrata, using broth microdilution assay. It can be inferred that S. terebinthifolia Raddi fruit has the potential to act as an ally in the search for new alternatives in the action against pathogens, and it can be used as a potential natural antioxidant and antimicrobial agent. Metals (Cu, Fe, Mg, Mn and Zn) were also determined by flame atomic absorption spectrometry (FAAS), with emphasis on high concentrations of Mg, Zn and Fe. investigated 1 chromatographydiode chromatography diode HPLCDAD HPLC DAD (HPLC-DAD applied 078 0 78 0.7 314 3 14 3.1 L1.

This study highlights the synthesis of innovative polyurethane materials derived from Moringa oleifera oils extracted from two distinct sources. The oils were converted into their respective polyols through the in situ generated performic acid method. Diverse material characteristics were observed due to different agroclimatic and cultivation conditions for the sources. Extraction yields were 45.21% (source 1) and 40.32% (source 2), with acid values of 28.70 and 26.00 mg KOH per g of oil, respectively. Oleic acid constituted 79.87 and 67.11% of the oils composition, respectively. Nuclear magnetic resonance and Fourier transform infrared spectroscopy (FTIR) confirmed the hydroxylation of the oils. FTIR also identified the isocyanate structures in the synthesized polyurethane materials. Gel permeation chromatography analysis revealed a higher oligomer content in the polyol synthesized from the oil extracted from source 2. Thermogravimetric analysis demonstrated enhanced thermal stability post-oil conversion, highlighting decomposition stages for rigid and flexible segments. Differential scanning calorimetry indicated higher unsaturation in the oil extracted from source 1, resulting in an elevated crystallization temperature. Tensile testing showed increased elasticity as the [NCO]/[OH] ratio decreased in the material, emphasizing the influence of polyol and crosslinking agent concentrations on mechanical resistance of polyurethane materials. sources method 4521 45 21 45.21 1 4032 40 32 40.32 2, 2 , 2) 2870 28 70 28.7 2600 26 00 26.0 respectively 7987 79 87 79.8 6711 67 11 67.11 composition (FTIR postoil post conversion segments temperature NCO/OH NCOOH NCO / OH [NCO]/[OH 452 4 45.2 403 3 40.3 287 7 28. 260 0 26. 798 8 79. 671 6 67.1 45. 40. 67.

This work aimed to incorporate the active compounds of the jambolan leaf in sunflower seed oil, in order to increase the nutritional quality of the oil. For this purpose, ultrasound-assisted extraction was conducted to establish the process conditions related to temperature, potency, solvent:sample ratio and time to obtain the enriched sunflower seed oil (ESSO). An experimental design was applied to examine the effect of variables (temperature, power, solvent:sample ratio and time) on the extraction mass yield (EMY). The application of maximum temperature, increased power, sample:solvent ratio and time resulted in higher EMY. Maximum theoretical EMY value was 35.16% (60 °C, 100%, 1:12 g mL-1 and 15 min). The characterization of the oils obtained from ESSO and sunflower seed oil (SSO) verified a higher content of flavonoids, phenolic compounds, a large proportion of active compounds, antioxidant activity, content of phytosterols, α-tocopherol and squalene, and induction time for ESSO. purpose ultrasoundassisted ultrasound assisted temperature potency solventsample solvent sample .

EFFECT OF LIQUID SWINE WASTEWATER DOSES ON PHYSICAL, CHEMICAL AND ELECTROCHEMICAL ATTRIBUTES IN A CERRADO OXISOL. The addition of organic residues enhances soil and plant organic matter and nutrient content. To gauge the impact of varying liquid swine waste (LSW) levels on soil, we studied changes in a clayey Oxisol’s physical, chemical, and electrochemical traits from the Cerrado. LSW doses (0, 50, 150, 450, 600 m3 ha−1) were applied to the 0-0.20 m layer in a randomized design with three replicates. Post a 30-day incubation at 60% field capacity, the soil underwent mineralogical, physical (clay dispersed in water - CDW), chemical (sodium adsorption ratio - SAR, cation exchange capacity - CEC, base saturation - V%), and electrochemical (pH in H2O and KCl, ApH, point of zero charge - PZC, point of zero salt effect - PZSE, surface electric potential - iµo, and electrical conductivity - EC) analyses. The levels of exchangeable Ca, K, Mg, Na, and available P increased with increasing LSW doses. Increasing LSW doses in the soil led to an increase in EC, but soil salinization was not observed at the highest dose. With the application of LSW doses, there was a decrease in pH, ApH, PZSE, and an increase in CEC, PZC and ψo. Despite the increase in ψo, low clay dispersibility was observed.

The training of Chemistry teachers in Brazil has been researched for a few decades and studies point out to training gaps that reverberate in teaching, especially in basic education. One of the contents covered in this step and which is part of the high school curriculum is radioactivity, which is related, among other things, to radiological and radioactive accidents that occur around the world. Thus, this research sought to investigate how the training provided to Chemistry undergraduates in the state of Goiás is in relation to the subject of radioactivity, since in 1987 a radiological accident occurred in Goiânia with a Cesium 137 source. This is a qualitative research, data were collected via questionnaire and the analytical technique used was discursive textual analysis (ATD). The results showed that due importance was not given to the radiological accident, since there is evidence of training gaps in relation to the topic of radioactivity in Chemistry degree courses in the state of Goiás, where the accident occurred, and the contents on radioactivity are either not addressed, or the approach is superficial. This fact directly impacts the teacher’s performance in basic education, when working on this content with their students. teaching education related things world Thus 198 13 source ATD. ATD .

Cupuaçu (Theobroma grandiflorum Schum.) is an Amazonian fruit rich in antioxidants potential due to its phenolic compounds. Its seeds produce cupulate, a chocolate-like product, and the residue remains rich in biocompounds. This study aimed to optimize and compare microwave-assisted (MAE) and high pressure/temperature extraction (HPTE) of polyphenolic and flavonoid compounds from cupuaçu seed by-products. A Box-Behnken 33 factorial design assessed the influence of extraction time, solid/liquid ratio, and ethanol concentration. Responses included total polyphenol content, total flavonoid content, and anti-radical power via the ABTS (2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid) method. In optimum conditions, MAE had the highest total polyphenol content and HPTE for flavonoids. Optimal conditions for both methods were 65% (m/v) ethanol concentration, 45 min extraction time, and 0.03 g mL−1 solid/liquid ratio. MAE and HPTE achieved greater recovery of (−)-epicatechin and (−)-epigallocatechin-3-gallate compared to percolation. Both techniques proved viable for recovering polyphenols from cupuaçu seed by-products, in less time and with less solvent. Thus, cupuaçu by-products can be a sustainable and functional food source, with MAE and HPTE providing high yields and quality extracts rich in polyphenols. Theobroma Schum.

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.

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.

The aim of this study was to effectively remove Fe2+ by using ozone microbubbles in bottled mineral water to prevent sediment from occurring during storage and increase shelf life. By considering the characteristics of mineral water with low solubility of ozone and high CO2 content, a suitable ozone injection step was chosen and a new mineral water treatment method using microbubbles was proposed. As a result of the treatment of the bottled mineral water with ozone microbubbles, the concentration of the iron ion was reduced from 0.14 to 0.01 mg L-1, and the shelf life increased to 360 days. During the treatment, the concentrations of K+ and Na+ were almost unchanged, and the deposition time was reduced to one-third compared to the natural oxidation.

RESUMO: O tomate (Solanum lycopersicum L.) é uma fruta rica em nutrientes e com alto teor de ácido glutâmico, tornando-o uma fonte adequada para a produção de ácido γ-aminobutírico (GABA) através da ação de bactérias ácido lácticas (BAL). As BAL desempenham um papel fundamental na fermentação láctica, melhorando o sabor e o valor nutricional dos produtos alimentares, contribuindo frequentemente para os seus benefícios para a saúde. Este estudo teve como objetivo isolar BAL produtoras de GABA de tomates e avaliar seu potencial para a produção de suco de tomate fermentado enriquecido com GABA. Os resultados indicam o isolamento de 15 cepas de BAL a partir de amostras de cinco tomates diferentes. Todas essas cepas demonstraram capacidade de produzir GABA, com níveis variando de 1,732 a 3,113 mg/mL, conforme determinado por cromatografia em camada delgada (CCD).

ABSTRACT: Tomatoes (Solanum lycopersicum L.) are nutrient-rich fruits with a high glutamic acid content, making them a suitable source for producing γ-aminobutyric acid (GABA) through the action of lactic acid bacteria (LAB). LAB plays a pivotal role in lactic fermentation, enhancing the taste and nutritional value of food products, often contributing to their health benefits. This study isolated GABA-producing LAB from tomatoes and assessed their potential for producing GABA-enriched fermented tomato juice. The results indicated the isolation of 15 LAB strains from the samples of five different tomatoes. All of these strains demonstrated the capability to produce GABA, with levels ranging from 1.732 to 3.113 mg/mL, as determined using thin-layer chromatography (TLC). Through sequencing, the promising strain TO42, identified as Weissella cibaria, was selected for tomato juice fermentation. Furthermore, GABA-enriched tomato juice was successfully fermented at 15 °Brix for 72 h, resulting in the highest recorded GABA and lactic acid content of 9.185 ± 0.398 mg/mL and 13.05 ± 1.56 g/L, respectively.

RESUMO: O ensino de anatomia vem se modificando ao longo dos anos, introduzindo métodos tecnológicos, principalmente após o período pandêmico. Questiona-se o uso exclusivo da tecnologia em comparação aos métodos tradicionais de dissecação e aulas teóricas presenciais no que diz respeito à aquisição de conhecimento. Este artigo analisou a percepção de conhecimento de alunos de diversos semestres do curso de Medicina Veterinária, comparando alunos que tiveram aulas apenas online com aqueles que tiveram aulas presenciais de Anatomia Descritiva dos Animais Domésticos. Para tanto, questões foram enviadas por meio de formulário, com preenchimento voluntário e anônimo, e posteriormente analisadas estatisticamente. Os resultados indicam que 11,5% dos alunos que cursaram a disciplina remotamente falharam na aplicação dos conhecimentos em outras disciplinas, enquanto nenhum aluno do ensino presencial relatou o mesmo. A maioria dos alunos, tanto dos grupos remotos quanto dos presenciais, lembram-se do assunto, mas revisam o conteúdo com frequência. Em relação ao conhecimento teórico, o grupo online (80,8%) compreendeu melhor à medida que o curso avançava, comparado a 59,6% do grupo presencial. A ligação entre Anatomia e outras disciplinas foi mais destacada pelo grupo presencial (30,8%) em comparação ao online (15,4%). Ambos os grupos concordam que o contacto físico com peças anatômicas é essencial, mas alguns consideram possível ter um primeiro contacto com imagens ou fotografias 3D. Baseado nesse estudo preliminar, conclui-se que as interações iniciais com a área de Anatomia devem incluir técnicas pedagógicas diversificadas com comunicação empática. A utilização de recursos tecnológicos modernos é um aliado do processo de ensino-aprendizagem, e após a abstração dos conteúdos é possível o uso singular da tecnologia na manutenção e atualização do conhecimento anatômico.

ABSTRACT: Anatomy teaching has been changing over the years, introducing technological methods especially after the pandemic period. An ongoing debate revolves around whether exclusive reliance on technology for anatomy classes, as opposed to traditional methods and face-to-face instruction, enhances knowledge acquisition. This study analyzed the knowledge perception of students from various semesters throughout the Veterinary Medicine course, comparing students who only had online classes with those who had face-to-face classes in Gross Anatomy of Domestic Animals. For this purpose, a questionnaire was distributed for voluntary and anonymous completion, and the responses were subsequently analyzed statistically. The results indicated that 11.5% of the students who took Anatomy remotely failed to apply the knowledge in other subjects, while no face-to-face learning student reported the same. Most students, both remote and face-to-face groups, remember the subject but review the content frequently. Regarding theoretical knowledge, the online group (80.8%) understood better as the course progressed, compared to 59.6% of the face-to-face group. The connection between Anatomy and other subjects was more highlighted by the face-to-face group (30.8%) compared to the online group (15.4%). Both groups agree that physical contact with anatomical specimens is essential; however, some believe that initial exposure through 3D images or photographs is feasible. We concluded based on this preliminary study that the initial interactions with the Anatomy field should include diversified pedagogical techniques with empathetic communication. The use of modern technological resources are allies in the teaching-learning process. Furthermore, after abstracting the contents, technology alone can effectively maintain and update anatomical knowledge.

RESUMO Regiões com climas semiáridos apresentam condições ambientais que resultam em estresses abióticos às plantas. A maior área de produção de melão (Cucumis melo L.) do Brasil, o Estado do Rio Grande do Norte, possui essas características climáticas. O uso de bioestimulantes nesses sistemas de produção pode mitigar os efeitos dos estresses abióticos e aumentar a produtividade e a qualidade dos frutos. O objetivo neste estudo foi avaliar as características fisiológicas e de produção do meloeiro, sob aplicação de bioestimulantes. Os bioestimulantes Acadian®, Folicist® e Nov@® foram aplicados e comparados ao tratamento controle (sem bioestimulantes), em melões ‘Goldex’ e ‘McLaren’. Nov@® proporcionou maior assimilação de CO2, transpiração e condutância estomática, assim como ascorbato peroxidase em ‘Goldex’ e ‘McLaren’. Maior catalase foi obtida pela aplicação de Nov@®, enquanto que o uso de Folicist® resultou em maior teor de malondialdeído. A cultivar McLaren apresentou o melhor desempenho fisiológico e bioquímico e a ‘Goldex’ o melhor rendimento. Folicist® promove adaptações fisiológicas aos estresses sem prejudicar a atividade fotossintética. Os bioestimulantes aumentaram a produtividade e o número de frutos por planta e promoveram adaptações fisiológicas às condições semiáridas. plantas Cucumis L.

ABSTRACT Regions with semi-arid climates have environmental conditions that result in abiotic stress to plants. The largest melon (Cucumis melo L.) production area in Brazil, the state of Rio Grande do Norte, has these climatic characteristics. Use of biostimulants in these production systems can mitigate effects of abiotic stress and increase yield and fruit quality. The objective in this study was to evaluate the physiological and production characteristics of melon, under the application of biostimulants. The biostimulants Acadian®, Folicist® and Nov@® were applied and compared to the control treatment (no biostimulants), in ‘Goldex’ and ‘McLaren’ melons. Nov@® led to higher CO2 assimilation, transpiration and stomatal conductance, as well as ascorbate peroxidase, in ‘Goldex’ and ‘McLaren’. Greater catalase was obtained with the application of Nov@®, while the use of Folicist® resulted in higher malondialdehyde content. The cultivar ‘McLaren’ exhibited the best physiological and biochemical performance, and ‘Goldex’ the best yield. Folicist® promotes physiological adaptations to stress without impairing photosynthetic activity. The biostimulants increased yield and number of fruits per plant and promoted physiological adaptations to semi-arid conditions. semiarid semi arid plants Cucumis L.
