Diaporthe phaseolorum, an endophyte isolated from Combretum lanceolatum, has exhibited diverse biological activities including antimicrobial, leishmanicidal, antitumoral, and herbicidal properties. Regardless of these activities, there remains limited research on its chemical constituents. Therefore, this study aimed to investigate the metabolome of D. phaseolorum employing mass spectrometry data dereplication through molecular networking and MolNetEnhancer tools. Twenty two molecular families were annotated, including prenol lipids, benzenoids, organoheterocyclic compounds, and nucleosides. Among the 41 nodes annotated, 36 metabolites were confirmed via spectral references, including alismol, farnesol, linoleic acid, tyramine, N-acetyl-tyramine, 5-methoxy-1H-indole-3-carbaldehyde, 6-pentyl-2H-pyran-2-one, and adenosine. Further node annotation was achieved through MolNetEnhancer, resulting in the classification of an additional 68 nodes into various molecular families. Consequently, this study represents a significant contribution to the identification of the D. phaseolorum metabolome, highlighting its secondary metabolites and providing valuable chemical insights to elucidate its demonstrated biological activities. lanceolatum antimicrobial leishmanicidal antitumoral properties constituents Therefore D tools annotated lipids benzenoids compounds nucleosides 4 3 references alismol farnesol acid tyramine Nacetyltyramine, Nacetyltyramine N acetyl N-acetyl-tyramine 5methoxy1Hindole3carbaldehyde, 5methoxy1Hindole3carbaldehyde methoxyHindolecarbaldehyde 5 methoxy 1H indole carbaldehyde, carbaldehyde H 5-methoxy-1H-indole-3-carbaldehyde 6pentyl2Hpyran2one, 6pentyl2Hpyran2one pentylHpyranone 6 pentyl 2H pyran 2 one, one 6-pentyl-2H-pyran-2-one adenosine Consequently Hindole Hpyran

This study aims to propose a new method for derivatizing fatty acids (FAs) from human milk (HM), eliminating the lipid extraction step, and simplifying the preparation for gas chromatography with a flame ionization detection (GC-FID) analysis to quantify the FAs. The Design Expert software optimized the reaction times, concentrations, and sample amount. The proposed method (PM) was validated for lyophilized HM and results for the figures of merit for precision in relative standard deviation (RSD) (RSDintra-day 1.34-4.03% and RSDinter day 2.08 5.16%), accuracy (99.87-102.16%), and robustness are within a linear range of 3 to 38% lipids in HM samples. The atmospheric solids analysis probe tandem mass spectrometry (ASAP-MS/MS) technique confirmed the efficiency of PM by expressing the molecular composition of triacylglycerol formed by FAs from the GC-FID technique. The PM requires a small sample size and conducts derivatization directly in the sample matrix, minimizing extraction errors.

Exploring the triacylglycerols composition in milk samples from different ruminant species is crucial for dairy product development. Identifying the fatty acid (FA) composition in human milk is essential and is usually performed using gas chromatography (GC). Heat maps are useful for visualizing these results, aiding in pattern identification and relationships between samples and variables. Additionally, nuclear magnetic resonance (NMR) spectroscopy provides important qualitative and quantitative information about fatty acids (FA). In the present study, we compare the fatty acid composition in samples of HM, cow milk, and goat milk, as well as to demonstrate their positional distribution in triacylglycerols (TAGs). Human milk contains 49.21% saturated fatty acids (SFAs), 34.32% monounsaturated fatty acids (MUFA), and 16.47% polyunsaturated fatty acids (PUFA), including 2.14% docosahexaenoic acid (DHA) and 13.02% linoleic acid (LA). On the other hand, cow and goat milk have higher proportions of SFAs (56.2 and 58.02%, respectively) and MUFAs (40.56 and 40.95%, respectively), but lower amounts of PUFAs (3.24 and 1.03%, respectively), with significantly lower quantities of DHA (0.03 and 0.43%, respectively) and LA (1.46 and 2.76%, respectively). Additionally, fatty acids in ruminant milk mainly consist of long-chain fatty acids (LCFAs), with oleic acid being the most abundant. development FA (FA GC. GC .

Gas chromatography coupled to mass spectrometry (GC-MS) has been widely used, and along with other methodologies such as derivatization, is a powerful tool to analyze phytocompounds, including cuticular wax components. The loss of structural information upon fragmentation of waxes makes it difficult to interpret and identify the GC-MS mass spectra of these compounds with the traditional methods, as digital libraries. Therefore, as a new complementary alternative to traditional methods of identifying aliphatic acyclic lipids based on mass spectra, we present the new software WaxAlly in this technical note. WaxAlly is a new software created based on simple algorithms, enabling the rapid recognition by the user of eight aliphatic acyclic lipid classes, including alkanes, alkenes, aldehydes, ketones, esters, and TMS derivatives of free fatty acids, primary and secondary alcohols, and their homologues with carbon chains varying between 10 and 100 carbons. Additionally, the WaxAlly software provides a section for data organization, internet comparison to NIST and PubChem databases, and academic information about mass fragmentation of acyclic lipids. The software has proven to be a very useful complementary technique in identifying plant wax lipid homologues, and new fragmentation patterns of lipid classes can be added in the future to improve the program.

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.

ABSTRACT: Sweet potato is an important food security crop, and the world market for this root is on the rise. Based on the physiological changes in plants in response to climatic conditions and fertilization, this study evaluated the effects of the growing season (rainy and dry season) and P2O5 doses (0, 50, 100, 200 and 400 kg ha-1) on total yield, marketable classes yields, as well as chemical composition of storage roots of two sweet potato cultivars. The storage roots yield was greater in the rainy season. The optimum agronomic and economic doses were 128 and 95 kg ha-1 P2O5 for the cultivar Canadense. Cultivar Uruguaiana did not respond to phosphate fertilization, but its storage roots had higher contents of dry matter, lipids, fibers, total and reducing sugars, and starch. Sweet potato cultivation in the rainy season with doses up to 100 kg ha-1 P2O5 increase root yield in marketable size classes in higher economic value and with higher carbohydrate contents. The results can help producers schedule the planting and harvesting of sweet potatoes throughout the year and contribute to the seasonal management of phosphate fertilizer application.

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 .

ABSTRACT Postharvest conservation of fresh fruits and vegetables is a constant challenge in the food industry. Biodegradable coatings represent an innovative and sustainable solution to extend their shelf life. In this context, this research evaluated the influence of a coating based on oxidized banana starch (Musa paradisiaca L. group AAA, cv. Cavendish) and olive oil on the conservation of cherry tomatoes (Solanum lycopersicum cv. Cerasiforme) during their storage at ambient conditions. Coating-forming emulsions were prepared using starch (4% m v-1) with a high degree of oxidation, glycerol, Tween 80, and olive oil. The products were dip coated. The starch extraction yield was 27.26% by the wet milling method. The contents of lipids, crude fiber, proteins, carbohydrates, and ashes tended to decrease in oxidized starches with increasing reaction time, the opposite behavior for humidity (P≤0.05). Solubility and oil absorption capacity increased in oxidized starches, while water absorption and swelling power decreased (P≤0.05). The best combination for the formulation of oxidized starch coatings was 3% (m v-1) of glycerol and 0.3% (m v-1) of oil. This coating reduced weight losses and delayed the ripening process. The results suggested that the use of coatings based on oxidized banana starch and olive oil is an effective strategy for maintaining the quality and freshness of the fruits during a longer storage period.

RESUMEN La conservación poscosecha de frutas y hortalizas frescas es un desafío constante en la industria alimentaria. Los recubrimientos biodegradables representan una solución innovadora y sostenible para prolongar su vida útil. En este contexto, esta investigación evaluó la influencia de un recubrimiento a base de almidón oxidado de plátano (Musa paradisiaca L. grupo AAA, cv. Cavendish) y aceite de oliva en la conservación de tomates cherry (Solanum lycopersicum cv. Cerasiforme) durante su almacenamiento en condiciones ambientales. Se prepararon emulsiones formadoras de recubrimiento usando almidón (4% m v-1) con alto grado de oxidación, glicerol, Tween 80 y aceite de oliva. Los productos se recubrieron mediante inmersión. El rendimiento de extracción del almidón fue de 27,26% por el método de molienda húmeda. Los contenidos de lípidos, fibra cruda, proteínas, carbohidratos y cenizas tendieron a disminuir en los almidones oxidados al aumentar el tiempo de reacción, comportamiento opuesto para la humedad (P≤0,05). La solubilidad y capacidad de absorción de aceite aumentaron en los almidones oxidados, mientras que la absorción de agua y poder de hinchamiento disminuyeron (P≤0,05). La mejor combinación para la formulación de los recubrimientos de almidón oxidado fue 3% (m v-1) de glicerol y 0,3% (m v-1) de aceite. Este recubrimiento redujo las pérdidas de masa y retrasó el proceso de maduración. Los resultados sugirieron que el uso de recubrimientos a base de almidón oxidado de plátano y aceite de oliva es una estrategia eficaz para mantener la calidad y frescura de los frutos durante un periodo de almacenamiento más prolongado.

Abstract Fermentation in a solid medium is a technique used for the production of chitin, pigments, proteins and lipids. In the present work, changes in the chemical and microbiological composition were evaluated in micro silages of shrimp (Litopeneus vanamei) and grasshopper (Sphenarium purpurascens) exoskeletons, fermented with a commercial inoculum of Lactobacillus plantarum AVG-112. The amount of molasses for fermentation, proximal composition and microbiological count of the silages, were determined. The waste was mixed with sugarcane molasses as a carbon source and inoculated using a commercial strain (Lactobacillus plantarum AVG-112). After 5 days of fermentation, both silages presented acceptable physical and chemical characteristics. Total coliforms, molds and yeasts were not present and were inhibited by the ensiling process. We concluded that fermentation in a solid medium has suitable characteristics for use as a food supplement for aquatic organisms.

Resumen La fermentación en medio sólido es una técnica utilizada para la producción de quitina, pigmentos, proteínas y lípidos. En el presente trabajo se evaluaron los cambios en la composición química y microbiológica en micro ensilados de exoesqueletos de camarón (Litopeneus vanamei) y chapulín (Sphenarium purpurascens) fermentados con un inoculo comercial de Lactobacillus plantarum AVG-112. Se determinó la cantidad de melaza para la fermentación, la composición proximal y la cuenta microbiológica de los ensilados. Los desechos se mezclaron con melaza de caña de azúcar como fuente de carbono y se inoculó usando una cepa comercial (Lactobacillus plantarum AVG-112). A los 5 d de fermentación ambos ensilados presentaron características físicas y químicas aceptables. Los coliformes totales, mohos y levaduras no estuvieron presentes siendo inhibidos por el proceso de ensilaje. Concluimos que la fermentación en medio sólido tiene características adecuadas para su utilización como suplemento en alimentos para organismos acuáticos.

SUMMARY: Formaldehyde induces oxidative damage in hippocampal tissue and blood serum by suppressing antioxidant defenses and increasing lipid peroxidation. This results in damage to DNA, proteins, and lipids within cells, disrupting neuronal functions, and may even lead to cell death (apoptosis). Apoptosis occurs as a cellular response triggered by formaldehyde through various mechanisms, including mitochondrial dysfunction, oxidative stress, and DNA damage. Arbutus unedo L. (AUL), which is rich in antioxidants, represents a potential countermeasure. The aim of our study is to investigate the immunohistochemical and biochemical effects of AUL fruit extract (AUE) on apoptosis and oxidative stress induced by FA exposure in the rat hippocampus. The rats were divided into four groups: the experimental group (EG) received 20 mg/kg AUE by oral gavage and 10 ppm FA inhalation; the formaldehyde group (FG) received 10 ppm FA inhalation only; the sham group (SG) received 10 mg/kg AUE by oral gavage; and the control group (CG) underwent routine observation. Hippocampal tissue was isolated after blood sampling. A number of physical changes, such as yellowing of feathers and tail spots, were observed in FA-exposed groups. The biochemical analysis showed significant differences in brain-derived neurotrophic factor (BDNF), malondialdehyde (MDA), GSH (Glutathione) and nitric oxide (NO) levels between the groups. The AUE-treated groups had reduced MDA levels, suggesting a potential reduction in oxidative stress, along with lower apoptotic cell rates in caspase-3 assessments. The FG rats had lower BDNF levels than CG. The SG had the fewest apoptotic cells. All these findings indicate AUE's potential to mitigate neuron damage and reduce oxidative stress.

RESUMEN: El formaldehído induce daño oxidativo en el tejido del hipocampo y del plasma sanguíneo al suprimir las defensas antioxidantes y aumentar la peroxidación lipídica. Esto provoca daños en el ADN, las proteínas y los lípidos dentro de las células, alterando las funciones neuronales e incluso puede provocar la muerte celular (apoptosis). La apoptosis se produce como una respuesta celular desencadenada por el formaldehído a través de diversos mecanismos, incluida la disfunción mitocondrial, el estrés oxidativo y el daño del ADN. Arbutus unedo L. (AUL), rico en antioxidantes, representa una posible contramedida. El objetivo de nuestro estudio fue investigar los efectos inmunohistoquímicos y bioquímicos del extracto de fruta AUL (AUE) sobre la apoptosis y el estrés oxidativo inducido por la exposición a FA en el hipocampo de rata. Las ratas se dividieron en cuatro grupos: el grupo experimental (GE) recibió 20 mg/kg de AUE por sonda oral y 10 ppm de FA por inhalación; el grupo de formaldehído (GF) recibió sólo una inhalación de 10 ppm de FA; el grupo simulado (GS) recibió 10 mg/kg de AUE mediante sonda oral; y el grupo control (GC) se sometió a observación de rutina. Se aisló tejido del hipocampo después de una muestra de sangre. En los grupos expuestos a FA se observaron una serie de cambios físicos, como coloración amarillenta del pelaje y manchas en la cola. El análisis bioquímico mostró diferencias significativas en los niveles de factor neurotrófico derivado del cerebro (BDNF), malondialdehído (MDA), GSH (glutatión) y óxido nítrico (NO) entre los grupos. Los grupos tratados con AUE tenían niveles reducidos de MDA, lo que sugiere una reducción potencial del estrés oxidativo, junto con tasas de células apoptóticas más bajas en las evaluaciones de caspasa-3. Las ratas GF tenían niveles de BDNF más bajos que GC. El GS tenía la menor cantidad de células apoptóticas. Todos estos hallazgos indican el potencial del AUE para mitigar el daño neuronal y reducir el estrés oxidativo.

ABSTRACT The use of CO2 sensors has been reported as an effective tool in the early detection of signs of deterioration, allowing good accuracy in decision-making about the quality of stored grains. The objective of this study was to quantify the CO2 levels produced by maize grains stored at ambient temperature in a prototype silo, with initial moisture contents of 14, 16 and 18% w.b., and to evaluate the quality of the product over time and the technical breakage. Analyses of moisture content, ash, proteins, lipids, Hue Angle (color), germination and electrical conductivity were performed. Inside the silos, the amount of CO2, relative air humidity and temperature were monitored every hour. Grain quality evaluations were carried out at four storage times (0, 30, 60 and 90 days). A completely randomized design in a 3 × 4 factorial scheme with six replicates was used. Grains with higher moisture contents showed higher technical breakage and losses associated with CO2 emissions. Moisture content, protein, lipids, germination, bulk density, lightness and chroma decreased over time, while the electrical conductivity increased, resulting in greater damage to membranes and loss of quality of maize grains. Monitoring of CO2 in the grain mass is a good tool to assess the quality of grain, and higher initial moisture content caused greater level of CO2 emission and reduction in quality of maize grains.

RESUMO O uso de sensores de CO2 tem sido reportado como uma medida eficaz na detecção precoce de sinais de deterioração, permitindo uma boa acurácia na tomada de decisão sobre a qualidade de grãos armazenados. Neste estudo objetivou-se quantificar os níveis de CO2 produzidos por grãos de milho armazenados em temperatura ambiente em silo protótipo, com teores de água iniciais de 14, 16 e 18% b.u., bem como avaliar a qualidade do produto ao longo do tempo e a quebra técnica. Foram realizadas análises de teor de água, cinzas, proteínas, lipídeos, Hue Angle (cor), germinação e condutividade elétrica. No interior dos silos foi monitorada a quantidade de CO2, umidade relativa do ar e temperatura a cada uma hora. As avaliações de qualidade dos grãos ocorreram em quatro tempos de armazenamento (0, 30, 60 e 90 dias). Foi usado o delineamento inteiramente casualizado, em esquema fatorial 3 × 4 e seis repetições. Os grãos mais úmidos apresentaram maior quebra técnica e perdas associadas a emissões de CO2. Os teores de água, proteína, lipídeos, germinação, massa específica aparente, L* e croma reduziram ao longo do tempo, enquanto que a condutividade elétrica aumentou, resultando em maior danificação das membranas e perda de qualidade dos grãos de milho. O monitoramento do CO2 na massa de grãos é uma boa ferramenta para avaliar a qualidade dos grãos, e maior teor de umidade inicial causou maior nível de emissão de CO2 e redução na qualidade dos grãos de milho.

RESUMEN: La mareína es un compuesto flavonoide que reduce la glucosa y los lípidos en sangre y tiene un efecto protector en la diabetes. Sin embargo, no se han dilucidado el efecto y los mecanismos de la mareína sobre la transición endotelial- mesenquimatosa renal en la enfermedad renal diabética (ERD). En este estudio, los datos de secuenciación unicelular sobre DKD se analizaron utilizando un método de bioinformación y los datos se sometieron a una agrupación de dimensiones reducidas. Se descubrió que las células endoteliales podían dividirse en cinco subgrupos. La secuencia de desarrollo de los subgrupos fue 0, 1, 4, 2 y 3, de los cuales el subgrupo 3 tenía el fenotipo más intersticial. La expresión de la proteína marcadora mesenquimatosa: vimentina (VIM), fibronectina (FN1) y receptor del factor de crecimiento de fibroblastos. 1 (FGFR1) aumentó con la conversión de subgrupos. En ratones db/db de 13 a 14 semanas de edad, que desarrollan complicaciones de DKD después de las 8 a 12 semanas de edad, la mareína redujo los niveles sanguíneos de glucosa, creatinina y nitrógeno ureico, mejoró el daño estructural en el tejido renal y redujo la deposición y expresión de colágeno de FN1 y VIM. Marein también aumentó el marcador de autofagia: Cadena ligera 3II/I (LC3II/I) y disminuyó la expresión de FGFR1 en el tejido renal. En un modelo de transición endotelial-mesenquimal, un nivel alto de glucosa indujo un cambio fenotípico en las células endoteliales de la vena umbilical humana. Marein disminuyó la migración de células endoteliales, mejoró la morfología de las células endoteliales y disminuyó la expresión de VIM y FN1. El uso del inhibidor de FGFR1, AZD4547, y del inhibidor de la autofagia, 3-metiladenina (3-MA), demostró aún más el efecto inhibidor de la mareína en la transición endotelial-mesenquimal inducida por niveles altos de glucosa al reducir la expresión de FGFR1 y regular positivamente la proteína marcadora de autofagia. , LC3II/I. En conclusión, este estudio sugiere que la mareína tiene un efecto protector sobre la transición endotelial-mesenquimatosa renal en la ERC, que puede estar mediada por la inducción de autofagia y la regulación negativa de la expresión de FGFR1.

SUMMARY: Marein is a flavonoid compound that reduces blood glucose and lipids and has a protective effect in diabetes. However, the effect and mechanism(s) of marein on renal endothelial-mesenchymal transition in diabetic kidney disease (DKD) have not been elucidated. In this study, single-cell sequencing data on DKD were analyzed using a bioinformation method, and the data underwent reduced dimension clustering. It was found that endothelial cells could be divided into five subclusters. The developmental sequence of the subclusters was 0, 1, 4, 2, and 3, of which subcluster 3 had the most interstitial phenotype.The expression of mesenchymal marker protein:Vimentin(VIM), Fibronectin(FN1), and fibroblast growth factor receptor 1 (FGFR1) increased with the conversion of subclusters. In db/db mice aged 13-14 weeks, which develop DKD complications after 8-12 weeks of age, marein reduced blood levels of glucose, creatinine, and urea nitrogen, improved structural damage in kidney tissue, and reduced collagen deposition and the expression of FN1 and VIM. Marein also up-regulated autophagy marker:Light chain 3II/I(LC3II/I) and decreased FGFR1 expression in renal tissue. In an endothelial-mesenchymal transition model, a high glucose level induced a phenotypic change in human umbilical vein endothelial cells. Marein decreased endothelial cell migration, improved endothelial cell morphology, and decreased the expression of VIM and FN1. The use of the FGFR1 inhibitor, AZD4547, and autophagy inhibitor, 3-Methyladenine(3-MA), further demonstrated the inhibitory effect of marein on high glucose-induced endothelial-mesenchymal transition by reducing FGFR1 expression and up-regulating the autophagy marker protein, LC3II/I. In conclusion, this study suggests that marein has a protective effect on renal endothelial- mesenchymal transition in DKD, which may be mediated by inducing autophagy and down-regulating FGFR1 expression.

Resumen Las vesículas extracelulares (EV) son estructuras esféricas delimitadas por membranas y producidas por varios tipos de células. En particular, las vesículas de membrana externa (OMV) son partículas nanométricas producidas constitutivamente por bacterias Gram negativas (GNB) en diferentes condiciones ambientales. Las OMV son biológicamente activas; están cargadas de lípidos, polisacáridos, proteínas e incluso diferentes tipos de ácidos nucleicos. Las OMV de bacterias orales patógenas desempeñan papeles clave en las interacciones patógeno-hospedero, constituyendo un posible vínculo entre la salud oral y las enfermedades sistémicas. Las OMV participan en la adhesión, la invasión y el daño celular, así como en la modulación de la respuesta inmunitaria del hospedero, la formación de biopelículas y la promoción de la virulencia. El objetivo de esta revisión sistemática era recopilar, analizar y sintetizar los conocimientos disponibles sobre las OMV de las GNB anaerobias orales patógenas más estudiadas. Esta información se clasificó en las siguientes categorías: inducción de la vesiculación y biogénesis, su liberación de la célula parental, contenido, internalización por otra célula hospedadora e interacción con la célula hospedadora. Se observó que las OMV más estudiadas son las de Porphyromonas gingivalis y Bacteroides spp. y, en menor medida, Aggregatibacter spp. y Treponema spp. Esta revisión sistemática ofrece una síntesis de los conocimientos actuales sobre las OMV, haciendo hincapié en la información disponible para los periodontopatógenos.

Abstract Extracellular vesicles (EV) are spherical structures limited by membranes and shed by several cell types. Specifically, outer membrane vesicles (OMVs) are nanometric particles constitutively produced by Gram-negative bacteria (GNB) under different environmental conditions. OMVs are biologically active; they are loaded with selected lipids, polysaccharides, proteins, and even different types of nucleic acids. OMVs from pathogenic oral bacteria play key roles in pathogen-host interactions, constituting a possible link between oral health and systemic disease. OMVs participate in adhesion, invasion, and damage to cells, as well as in modulating the host's immune response, biofilm formation, and promotion of virulence. The objective of this systematic review was to collect, analyze and synthesize the knowledge available on literature reviews on OMVs of the most studied pathogenic oral anaerobic GNB. This information was classified into the following categories: induction of vesiculation and biogenesis, its liberation from the parental cell, content, internalization by another host cell, and the interaction with the host cell. It was found that the most studied OMVs are those of Porphyromonas gingivalis and Bacteroides spp. and, to a lesser extent, Aggregatibacter spp., and Treponema spp. This systematic review provides a synthesis of the current knowledge regarding OMVs, with emphasis on the information available for periodontopathogens.

ABSTRACT: Psidiummyrtoides fruits food industries produce by-products such as liqueurs, ice cream, jellies, and juices. However, there needs to be more information about the nutritional composition of fruits, as well as the biological potential, mainly of seed flour.Therefore, the present study aimed to evaluate the nutritional composition and antioxidant and cancer chemopreventive activities of pulp and seed of fruits of Psidiummyrtoides. Moisture content, total minerals and mineral profile, total lipids and fatty acids profile, total proteins, dietary fiber (soluble and insoluble) and total carbohydrates were analyzed. Vitamins C and complex B, organic acids and the profile of phenolic compounds were also determined. DPPH and ABTS methods evaluated the antioxidant activity, and cancer chemopreventive activity was evaluated by quinone reductase induction and NF-κB inhibitory activity. The fruits are a good source of thiamine, iron, phosphorus, potassium, fiber, and protein. Linoleic acid was the major fatty acid in both pulp and seed. Quercetin (1600 µg/100g) and pyrogallol(819 µg/100g) were the major phenolic compounds pulp and seed, respectively. The fruits showed strong antioxidant capacity, mainly the seeds, and the ability to induce quinone reductase activity, highlighting a cancer chemopreventive activity. Seed flour has a high potential to enrich food, in addition to valuing agro-industrial by-products, where we can highlight 25%, 13% and 37% of the recommended daily intake for iron (1.6 mg/100g), phosphorus (58 mg/100g) and vitamin B1 (450 µg/100g), respectively, in addition to antioxidant and cancer chemopreventive activities.

RESUMO: Frutos de Psidium myrtoides são utilizados na produção de subprodutos como licores, sorvetes, geleias e sucos, porém, existem poucas informações sobre a composição nutricional das frutas, bem como o potencial biológico, principalmente da farinha de sementes. Dessa forma, o objetivo do presente estudo foi avaliar a composição nutricional e as atividades antioxidante e quimiopreventiva de câncer da polpa e sementes de frutos Psidium myrtoides. Foram analisados o teor de umidade, minerais totais e perfil de minerais, lipídios totais e perfil de ácidos graxos, proteínas totais, fibra alimentar (solúvel e insolúvel) e carboidratos totais. Também foram determinadas as vitaminas C e do complex B, ácidos orgânicos e perfil de compostos fenólicos. A atividade antioxidante foi avaliada pelos métodos DPPH e ABTS, e a atividade quimiopreventiva de câncer foi avaliada pela indução da enzima quinona redutase e pela atividade inibitória do NF-κB. Os resultados mostraram que os frutos são boas fontes de vitamina B1, ferro, fósforo e potássio, além de fibras (polpa: 7%; semente: 25%) e proteínas. O ácido linoléico foi o principal ácido graxo tanto na polpa quanto na semente. Quercetina (1600 µg/100g) e pirogalol (819 µg/100g) foram os principais compostos fenólicos encontrados na polpa e na semente, respectivamente. A fruta apresentou forte capacidade antioxidante, principalmente as sementes, que também apresentam capacidade de induzir a atividade da enzima quinona redutase, ressalando atividade quimiopreventiva de câncer. A farinha de semente tem grande potencial para enriquecer alimentos, além de valorizar subprodutos agroindustriais, em que podemos destacar 25%, 13% e 37% da ingestão diária recomendada para ferro (1,6 mg/100g), fósforo (58 mg/100g) e vitamina B1 (450 µg/100g), respectivamente, além de atividades antioxidantes e quimiopreventivas do câncer.

ABSTRACT Cassava wastewater (CWW) is a natural biofertilizer successfully tested as a source of K in long-cycle crops; however, it still needs to be better evaluated in short-cycle crops. This study aimed to evaluate the use of CWW as a source of K in the growth, yield, and physicochemical quality of curly lettuce. The study was conducted in a greenhouse, in a randomized block design arranged in a 5 × 2 + 1 factorial scheme, with four replicates. Five CWW doses were evaluated as an exclusive source of K: 0, 60, 120, 180, and 240 kg ha-1 of K2O; two forms of application: 1-total dose at planting: 2-application of 50% of the dose at planting + 50% of the dose in topdressing, and an additional treatment: 100% mineral fertilization at 120 kg ha-1 of K2O dose, using KCl as the source. The number of leaves (NL), plant height (PH), fresh mass (FM), dry mass (DM), moisture (MO), ashes (ASH), fibers (FB), lipids (LIP), proteins (PTN), and carbohydrates (CHO) contents were evaluated. All agronomic attributes of lettuce showed lower values when fertilized only with CWW than mineral fertilization. Lettuce fertilized only with CWW, depending on total or split application and dose, showed higher ASH, FB, LIP, PTN, and CHO contents reaching 4.05, 3.97, 1.75, 7.11, and 3.63%, respectively, compared to mineral fertilization. The CWW can potentially be used as a complementary K source in lettuce cultivation, as its exclusive use does not replace traditional mineral fertilization.

RESUMO Água residuária de mandioca (ARM) é um biofertilizante natural que foi testado com sucesso como fonte de K para culturas de ciclo longo; entretanto, ainda precisa ser melhor avaliado em culturas de ciclo curto. Este estudo teve como objetivo avaliar a utilização do ARM como fonte de K no crescimento, produção e qualidade físico-química da alface crespa. O estudo foi realizado em casa de vegetação, em delineamento de blocos casualizados, em esquema fatorial 5 × 2 + 1, com quatro replicações. Foram avaliadas cinco doses de ARM como fonte exclusiva de K: 0, 60, 120, 180 e 240 kg ha-1 de K2O; duas formas de aplicação: 1-dose total no plantio: 2-aplicação de 50% da dose no plantio + 50% em cobertura, e um tratamento adicional: adubação 100% mineral com dose de 120 kg ha-1 de K2O, utilizando KCl como fonte. O número de folhas (NF), altura da planta (AP), massa fresca (MF), massa seca (MS), umidade (UM), conteúdos de cinzas (CZ), fibras (FB), lipídios (LIP), proteínas (PTN) e carboidratos (CHO) foram avaliados. Todos os atributos agronômicos da alface avaliados apresentaram valores inferiores quando adubada apenas com ARM comparado à adubação mineral. A alface adubada apenas com ARM, dependendo da aplicação total ou parcelamento e da dose, apresentou maiores teores de CZ, FB, LIP, PTN e CHO atingindo 4,05, 3,97, 1,75, 7,11 e 3,63%, respectivamente, em comparação à adubação mineral. A água residuária de mandioca pode potencialmente ser utilizado como fonte complementar de K na produção de alface, pois seu uso único não substitui a adubação mineral.
