Use of the electronic tongue as a tool for the characterization of Melipona scu...
Nascimento, Andreia Santos do; Silva, Fabiane de Lima; Machado, Cerilene Santiago; Silva, Samira Maria Peixoto Cavalcante; Estevinho, Leticia M.This study aimed to characterize honey of Melipona scutellaris regarding its physicochemical parameters using the electronic tongue (e-tongue) technique combined with the multivariate statistical analysis for honey differentiation. Physicochemical parameters were evaluated following official methods of chemical analyses. A potentiometric electronic tongue with 16 cross-sensitivity sensors was used for the analy...
Botanical origin, microbiological quality and physicochemical composition of th...
Oliveira, Daiane de Jesus; Santos, Daiane Rodrigues dos; Andrade, Brunelle Ramos; Nascimento, Andreia Santos do; Silva, Macela Oliveira daMelipona scutellaris Latreille, 1811 is of economic importance for local beekeepers, besides its relevance in the pollination of native plant species of the Brazilian Atlantic forest. Currently, data on the use of floral resources by Meliponini colonies are scarce, particularly in urban environments. We evaluated the botanical origin, the microbiological and physicochemical characteristics of pollen stored by M...
Phytochemical study and antioxidant activity of Dalbergia ecastaphyllum
Lucas, Cátia Ionara Santos; Ferreira, Adailton Freitas; Costa, Maria Angélica Carvalho; Silva, Fabiane de Lima; Estevinho, Leticia M.The chemical profile of Dalbergia ecastaphyllum has been indicated as the botanical origin of Brazilian red propolis, an apicultural product with proven therapeutic properties. However, few studies have investigated this plant species. This study evaluated and compared microbiological quality, chemical composition, and antioxidant activity of stem and leaf samples of D. ecastaphyllum. The samples were collected...
Características dos componentes de ovos da linhagem Ross de idades diferentes v...
Traldi, Ana Beatriz; Silva, Fabiane de Lima; Hongyu, Kuang; Sartorio, Simone Daniela; Menten, José Fernando MachadoDois experimentos foram conduzidos com o objetivo de avaliar a relação das características das componentes dos ovos, provenientes de ovos de pesos semelhantes ou distintos, produzidos por matrizes da linhagem Ross de idades diferentes. No experimento I foram utilizados 2.340 ovos e 2.160 ovos para o experimento II. Em cada um dos experimentos, uma amostra de 50 ovos foi selecionada dentro do peso determinado pa...
Dalbergia ecastaphyllum leaf extracts: in vitro inhibitory against enzymes rela...
Morais, Daniel Vieira; Moreira, Manuela M.; Silva, Fabiane de Lima; Costa, Maria Angélica Carvalho; Delerue-Matos, CristinaFor the first time, the anti-hemolytic activity and the enzyme inhibitory activities of Dalbergia ecastaphyllum leaves extracts were tested against α-amylase, α-glucosidase, lipase, acetylcholinesterase, butyrylcholinesterase, tyrosinase and hyaluronidase. The phenolic profile of the obtained extracts was also investigated by high-performance liquid chromatography with photodiode array detection (HPLC-PAD). The...

Antioxidant, photoprotective and inhibitory activity of tyrosinase in extracts ...
Morais, Daniel Vieira; Costa, Maria Angélica Carvalho; Bárbara, Marivalda; Silva, Fabiane de Lima; Moreira, Manuela M.; Delerue-Matos, CristinaDalbergia ecastaphyllum is a native Brazil plant with importance for beekeeping, and widely used in folk medicine. For the first time, the extracts of this plant were assessed for the presence of hydrophilic and lipophilic antioxidants, as well as inhibition of tyrosinase, free radicals scavenging and sunscreen protection. The antioxidant activity was evaluated by free radical scavenging (DPPH) andβ-carotene bl...

Performance and intestinal health of weanling pigs fed with dietary nucleotides
Andrade, Carla de; Almeida, Vivian Vezzoni de; Sbardella, Maicon; Perina, Danilo do Prado; Silva, Fabiane de Lima; Berenchtein, BernardoPrevious studies reported benefits to growth performance, intestinal histology and reduced diarrhea for pigs supplemented with nucleotide additive as a replacement to antimicrobial growth promoters. The purpose of this study was to evaluate the effects of nucleotide levels on performance, occurrence of diarrhea, relative weight of organs, intestinal histology, and intestinal microbiota of weanling pigs. One hun...
