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 ...
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 ...
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...
Preliminary assessment of the nutritional composition of underexploited wild le...
Carvalho, Ana Fontenele Urano; Farias, Davi Felipe; Rocha-Bezerra, Lady Clarissa Brito da; Sousa, Nathanna Mateus de; Cavalheiro, Mariana GiovenardiThe seeds of 14 wild legume species from Brazil were analyzed to assess their potential as food. The seeds showed high levels of crude protein (10.9–50.0%), dietary fiber (0.8–52.3%) and energy (905–1804 kJ 100 g 1 ), and the amino acid composition (mg g 1 N) was comparable to that of soybeans, but with higher amounts of lysine (456–10,884) and histidine (199–918). The seeds showed lectin activity (20– 2560 and...
Protein fractions, amino acid composition and antinutritional constituents of h...
Vasconcelos, Ilka Maria; Maia, Fernanda Maria Machado; Farias, Davi Felipe; Campello, Claudio Cabral; Carvalho, Ana Fontenele UranoHigh-yielding cowpea (Vigna unguiculata) cultivars were analysed for major changes in seed protein types, amino acid profiles and antinutritional factors content. As usual, the globulins constitute the major seed proteins (493.2–573.3 g kg 1 total seed protein), followed by albumins (201.0–248.0 g kg 1 ), basic glutelins (119.1–154.3 g kg 1 ), acid glutelins (82.4–92.3 g kg 1 ) and prolamins (13.2–20.2 g kg 1 )...
Desenvolvimento e performance reprodutiva de camundongos Swiss em ambiente enri...
Carvalho, Ana de Fátima F. Urano; Araújo, Ana Jérsia; Farias, Davi Felipe; Rocha-Bezerra, Lady Clarissa Brito da; Cavalheiro, M. G.The present study investigated the effects of environment enrichment on the development and reproductive perform ance of an outbred Swiss strain. Physical enrichment consisted of free access of animals to tubular devices of different shapes and sizes. The development evaluation was done by monitoring growth rate during 39 days, from weaning (21 days) to the onset of sexual maturity (60 days of age). Over five c...
Nutritive and non-nutritive attributes of washed-up seaweeds from the coast of ...
Oliveira, Maria Nilka de; Freitas, Ana Lúcia Ponte; Carvalho, Ana Fontenele Urano; Sampaio, Thereza Maria Tavares; Farias, Davi FelipeThis study assesses the nutritive and non-nutritive attributes of washed-up seaweeds from the Brazilian coast. It covers a broad diversity of species (24 red, nine green and four brown) with reasonable levels of proteins (10–14.8%), high ash contents (13–25%), low lipids (below 1%) and high carbohydrate contents (60%). Toxic and/or antinutritional factors were detected, such as low levels of lectins (32 and 64 ...
Proteínas de sementes de Amburana cearensis (Allemao) A. C. Smith: valor nutric...
Farias, Davi FelipeAmburana cearensis (Allemao) A. C. Smith, usually known in portuguese language as “Imburana-de-Cheiro” or “Cumaru”, is a leguminous tree, subfamily Papilionoideae with common occurrence in “Caatinga” Dominium. Despite the numerous ethnobotanical uses, few studies report biological activities of medical interest and / or agribusiness for this species or yet its utilization as food for humans and / or animals. Th...
