Diversidade da Composição Química dos Óleos Essenciais de Eugenia–Myrtaceae: um...
Silveira, Raisa Maria; Carvalho, Ana Fontenele Urano; Bünger, Mariana de Oliveira; Costa, Itayguara Ribeiro daMyrtaceae is a pantropical family with approximately 132 genera and 5.760 species. In the family, essential oilsare widely produced by their representatives, to the point that the presence of their secretory structures are used in taxonomic identification.This is the case of the species of Eugenia, the largest neotropical genusof Myrtaceae, comprising more than 1000 species.The aim of the present work was to ca...
Assessing the effects of an acute exposure to worst-case concentration of Cry p...
Vieira, Leonardo; Hissa, Denise Cavalcante; Souza, Terezinha; Gonçalves, Íris Flávia Sousa; Evaristo, José Alberto Medeiros; Nogueira, Fábio César SousaCry1C, Cry1F e Cry1Ab são proteínas inseticidas de Bacillus thuringiensis(Bt) que são expressos em culturas transgênicas. Dada a entrada dessas proteínas em ambientes aquáticos, é relevante avaliarseus impactos nos organismos aquáticos. Neste trabalho, buscamos avaliar os efeitos de Cry1C, Cry1F eCry1Ab na zebrafish embriões e larvas de uma concentração prevista de pior cenário destes proteínas (definido para 1...
Novel surfactant proteins are involved in the structure and stability of foam n...
Hissa, Denise Cavalcante; Vasconcelos, Ilka Maria; Carvalho, Ana Fontenele Urano; Nogueira, Vanessa Lúcia Rodrigues; Cascon, PauloMany amphibians lay their eggs in foam nests, which allow the eggs to be deposited out of the water. Analysis of some of these foam nests has revealed that they are a rich source of proteins with unusual primary structures and remarkable surfactant activity, named ranaspumins. The aim of this work was to study the foam nests of the frog Leptodactylus vastus in order to obtain information regarding their composi...

Triplaris gardneriana seeds extract exhibits in vitro anti-inflammatory propert...
Lopes Neto, José Joaquim; Almeida, Thiago Silva de; Almeida Filho, Luiz Carlos Pereira; Rocha, Talita Magalhães; Nogara, Pablo AndreiEthnopharmacological relevance: Triplaris gardneriana Wedd. (Polygonaceae family) is a plant species from Brazilian semiarid region which is used in local traditional medicine for the treatment of inflammatory condi tions such as hemorrhoids. Aim of the study: In this study, the in vitro anti-inflammatory activity of different concentrations of ethanolic extract from T. gardneriana seeds (EETg) was performed in...
Chemical composition, nutritional properties, and antioxidant activity of Lican...
Medeiros, Jackeline Lima de; Almeida, Thiago Silva de; Lopes Neto, José Joaquim; Almeida Filho, Luiz Carlos Pereira; Ribeiro, Paulo Riceli VasconcelosLicania tomentosa is a Brazilian plant species that produces edible fruits, yet there is little information available concerning their nutritional and/or bioactive composition. This study aimed to evaluate the nutritional and polyphenol composition of L. tomentosa fruits (pulp and seeds) and measure antioxidant activity in ethanolic extracts.The pulp and seeds were excellent sources of fiber (25.62%–41.70%) as ...
Insulin-like plant proteins as potential innovative drugs to treat diabetes—The...
Paula, Paulo C.; Oliveira, José Tadeu Abreu de; Sousa, Daniele de Oliveira Bezerra de; Alves, Bella Giselly Torres; Carvalho, Ana Fontenele UranoVarious plant species have long been used in traditional medicine worldwide to treat diabetes. Among the plant-based compounds with hypoglycemic properties, studies on insulin-like proteins isolated from leaves, fruits and seeds are rarely reported in the relevant literature. Our research group has been investigating the presence of insulin-like proteins in Moringa oleifera, a plant species native to India, and...
Castor bean cake contains a trypsin inhibitor that displays antifungal activity...
Silva, Rodolpho Glauber Guedes; Vasconcelos, Ilka M.; Bastos Filho, Acrísio José Uchôa; Carvalho, Ana Fontenele Urano; Souza, Terezinha M.A novel trypsin inhibitor, named RcTI, was purified from castor bean cake (Ricinus communis L.) by heat treatment followed by chromatography on anhydrotrypsin-Sepharose 4B and Resource Q. RcTI is a 14 kDa competitive inhibitor with pI 5.2 and a dissociation constant (Ki) of 1.9 × 10−5 mM. The amino-terminal sequence showed similarity with a 2S sulfur-rich seed storage protein (83%) and napin-like protein (48%)....
Food safety assessment of Cry8Ka5 mutant protein using Cry1Ac as a control Bt p...
Farias, Davi Felipe; Viana, Martônio Ponte; Oliveira, Gustavo Ramos; Santos, Vanessa Olinto; Pinto, Clidia Eduarda Moreira; Viana, Daniel AraújoCry8Ka5 is a mutant protein from Bacillus thuringiensis (Bt) that has been proposed for developing trans genic plants due to promising activity against coleopterans, like Anthonomus grandis (the major pest of Brazilian cotton culture). Thus, an early food safety assessment of Cry8Ka5 protein could provide valu able information to support its use as a harmless biotechnological tool. This study aimed to evaluate ...
Nutritional ranking of 30 Brazilian genotypes of cowpeas including determinatio...
Carvalho, Ana Fontenele Urano; Sousa, Nathanna Mateus de; Farias, Davi Felipe; Rocha-Bezerra, Lady Clarissa Brito da; Silva, Renata Maria Pereira daThis study aimed to establish a nutritional ranking of 30 genotypes of cowpea (Vigna unguiculata L. Walp). The results showed the proximate composition varies among genotypes in protein (20–30%) and dietary fiber contents (20–35%), in protease inhibitors (2–4 UI/mg protein), lectin (40,000–640,000 UH/kg meal) and essential amino acid levels, in vitro protein digestibility (30–40%) and in the apparent concentrat...
