Desenvolvimento de membranas e hidrogéis com extrato aquoso e etanólico de Caes...
Cunha, Arcelina Pacheco; Almeida, Raimundo Rafael de; Ribeiro, Ana Carolina Barbosa; Oliveira, Cristiane Pinto; Gomes, Elis Cristina ChagasAs queimaduras são as causas mais comuns de lesões cutâneas. Para dinamizar o processo de cicatrização são utilizados polímeros naturais em substituição aos polímeros sintéticos. A pectina e a galactomanana de jucá (Caesalpinia ferrea) e o alginato reticulado com cálcio são atóxicos e biodegradáveis. E juntamente com os extratos dos frutos do jucá apresentaram propriedades bactericidas e toxicidade baixa, agem ...
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...
Evaluation of cytotoxic and antimicrobial effects of two Bt cry proteins on a G...
Farias, Davi Felipe; Viana, Martônio Ponte; Oliveira, Gustavo Ramos de; Beneventi, Magda Aparecida; Soares, BrunoMarques; Pessoa, ClaudiaStudies have contested the innocuousness of Bacillus thuringiensis (Bt) Cry proteins to mammalian cells as well as to mammals microbiota.Thus, this study aimed to evaluate the cytotoxic and antimicrobial effects of two Cry proteins, Cry8Ka5 (a novelmutant protein) and Cry1Ac (a widely distributed protein in GM crops). Evaluation of cyto- and genotoxicity in human lymphocytes was performed as well as hemolytic a...
