Protective effect of natural and processed coconut water by non-thermal technol...
Miguel, Thaiz Batista Azevedo Rangel; Porto, Elaine Cristina Maciel; Pinheiro, Sergimar Kennedy de Paiva; Miguel, Emilio de CastroCoconut water is widely consumed and appreciated due its sensory, nutritional, and functional characteristics. Despite being widely consumed, this beverage has a short shelf life that can be improved through processing technologies including nonthermal technologies. Although this processing is promising, it also can generate toxic bioactive compounds of natural and synthetic origin. Their safety has been long d...
Hydrochar from sugarcane industry by-products: assessment of its potential use ...
Fregolente, Laís Gomes; Santos, João Vitor dos; Mazzati, Felipe S.; Miguel, Thaiz Batista Azevedo Rangel; Miguel, Emilio de CastroBackground: Hydrothermal carbonization (HTC) is a thermochemical process to convert biomass in carbon-rich materials (hydrochar). The use of sugarcane industry by-products in HTC has been evaluated, generating a hydrochar rich in nutrients, which could be used as a soil conditioner. We raised the hypothesis that the application of hydrochar in soil can improve its nutrient characteristics, bringing a better env...
Ontogenesis and secretion mechanism of Morinda citrifolia L. (Rubiaceae) colleters
Pinheiro, Sergimar Kennedy de Paiva; Teófilo, F.B.S.; Lima, A.K.M.; Cordoba, Bianca Vasconcelos; Miguel, Thaiz Batista Azevedo RangelColleters are secretory structures present in more than 60 families of angiosperms, whose function is protecting the leaf primordium and meristem against biotic and abiotic damage. The colleters are developed from protoderm and ground meristem and the secretory process begins during cell differentiation. The secretion is a complex phenomenon of synthesis, separation and isolation of substances, as well as relea...
Toxicity evaluation of process water from hydrothermal carbonization of sugarca...
Fregolente, Laís Gomes; Miguel, Thaiz Batista Azevedo Rangel; Miguel, Emilio de Castro; Melo, Camila de Almeida; Moreira, Altair BeneditoHydrothermal carbonization (HTC) is a thermochemical process carried out in an aqueous medium. It is capable of converting biomass into a solid, carbon-rich material (hydrochar), and producing a liquid phase (process water) which contains the unreactive feedstock and/or chemical intermediates from the carbonization reaction. The aim of this study was to evaluate the characteristics of process water generated by...
Seed structure in Canavalia brasiliensis Mart. ex Benth. (Leguminosae) and subc...
Miguel, Emilio de Castro; Miguel, Thaiz Batista Azevedo Rangel; Pireda, S.; Marques, Jonas de Brito Campolina; Cunha, Maura da; Cajazeiras, João BatistaLectins are proteins capable of specific and reversible recognition of carbohydrates without modifying them. Many studies have isolated these molecules from Leguminosae seeds but little attention was given to subcellular localization and biological function of these molecules. Therefore, this work aimed to describe Canavalia brasiliensis seed structure and the subcellular localization of ConBr. In addition, we ...
Dioclea violacea lectin ameliorates oxidative stress and renal dysfunction in a...
Freitas, Flavia P. S.; Porto, Marcella L.; Tranhago, Camilla P.; Piontkowski, Rogerio; Miguel, Emilio de Castro; Miguel, Thaiz Batista Azevedo RangelAcute kidney injury (AKI) is characterized by rapid and potentially reversible decline in renal function; however, the current management for AKI is nonspecific and associated with limited supportive care. Considering the need for more novel therapeutic approaches, we believe that lectins from Dioclea violacea (Dvl), based on their antiinflammatory properties, could be beneficial for the treatment of AKI induce...
Environmental scanning electron microscopy (ESEM) of Morinda citrifolia L. (Rub...
Pinheiro, Sergimar Kennedy de Paiva; Sousa, Francinalda Xavier de; Medeiros, Paulo Rafael Lima de; Miguel, Thaiz Batista Azevedo RangelThis study describes the colleters of Morinda citrifolia L. (Rubiaceae) by using environmental scanning electron microscopy (ESEM) and energy dispersive x-ray spectroscopy (EDS). Two different developmental stages were characterized as well as the chemical composition of secretion. Colleters are secretory structures that produce mucilage protecting the meristems and leaf primordia against desiccation and/or pat...
Morphology, ultrastructure and immunocytochemistry of Hypnea cervicornis and Hy...
Miguel, Thaiz Batista Azevedo Rangel; Schmidt, Eder C.; Bouzon, Zenilda Laurita; Nascimento, Fernando E.P.; Cunha, Maura da; Fernandes, Saulo PiredaBased on their morphological and physiological features, red algae comprise a complex and variable group of multiple genera, including Hypnea. In particular, the genus Hypnea J.V. Lamouroux (Cystocloniaceae, Rhodophyta) consists of approximately 54 species, including Hypnea cervicornis and H. musciformis. Lectins were described for both species; however, the localization of these proteins is still unclear. Ther...
Purification, partial characterization and immobilization of a mannose-specific...
Pinto Júnior, Vanir Reis; Santiago, Mayara Queiroz de; Osterne, Vinícius José da Silva; Correia, Jorge Luis AlmeidaLectin from the seeds of Dioclea lasiophylla (DlyL) was purified in a single step by affinity chromatography on a Sephadex® G-50 column. DlyL strongly agglutinated rabbit erythrocytes and was inhibited by monosaccharides (D-mannose and α-methyl-Dmannoside) and glycoproteins (ovalbumin and fetuin). Similar to other Diocleinae lectins, DlyL has three chains, α, β and γ, with mass of 25,569 ± 2, 12,998 ± 1 and 12,...
Morfoanatomia de Ricinus communis L. (Euphorbiaceae) expostas a estresse salino
Oliveira, Marilaine Alves de; Barros, Ivana Menezes Silva de; Pereira, Pedro Mazzocco; Pompilho, Wendel Mattos; Miguel, Thaiz Batista Azevedo RangelThe castor bean is an Euphorbiacea widely distributed throughout the Brazilian territory, where easly adapted. Its ability to adapt to different conditions and their resistance to water deficit, allow its development into infertile soil and in adverse conditions for most plants. Its culture is considered quite rustic, however, is sensitive to the physical and chemical characteristics of the soil as particle siz...
