A new lectin from Aplysia dactylomela eggs (ADEL) was isolated by affinity chromatography on HClactivated Sepharose™ media. Hemagglutination caused by ADEL was inhibited by several galactosides, mainly galacturonic acid (Ka = 6.05 × 106 M−1 ). The primary structure of ADEL consists of 217 residues, including 11 halfcystines involved in five intrachain and one interchain disulfide bond, resulting in a molecular ...
Lectin 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,...
Durante a educação básica, o conteúdo de imunologia é dificilmente trabalhado. Nas aulas sobre o sistema circulatório é que são abordadas as células do sistema imune e apresentadas aos educandos. Deste modo, o presente estudo tem o objetivo de apresentar os resultados obtidos com os encontros realizados com alunos da 1ª série do ensino médio da escola profissionalizante Dona Creusa do Carmo Rocha localizada na ...
A ação extencionista "Imunologia em Escolas Profissionalizantes de Fortaleza-CE (Projeto Imuno-Ensina UFC) é um projeto realizado por docentes da disciplina de imunologia da Universidade Federal do Ceará (UFC) juntamente com estudantes da graduação e pós-graduação de áreas interdisciplinares tanto da UFC quanto de outras instituições de ensino superior de Fortaleza. O projeto também conta com o apoio do Laborat...
Os vegetais são conhecidos por produzir grande variedade de compostos ativos que atualmente têm se tornando importantes na busca de novos fármacos. De fato, extratos vegetais tem demonstrado efeito antimicrobiano, atuando sobre formas planctônicas e inibindo a formação de biofilmes. Diante do exposto, o objetivo deste trabalho foi avaliar o efeito antimicrobiano e antibiofilme de extratos hexânicos de diferente...
During the past few deeades has been established a great advanee related to the etiology and dental earie prevention. However, epidemiologie data have demonstrated that it continues to be the most prevalent disease among ali others in odontology. One important etiologie faetor for this disease is the formation of a pathogenie baeteria biofilm that adheres to the dental surfaee, produeing aeids that lead to dent...
PINHEIRO, Aryane de Azevedo et al. Projeto imuno ensina UFC: ensino de imunologia para alunos de escolas profissionalizantes de Fortaleza. Imunologia em escolas profissionalizantes de Fortaleza-CE, FM00.2015.PJ.0183.; A ação extencionista "Imunologia em Escolas Profissionalizantes de Fortaleza-CE (Projeto Imuno-Ensina UFC) é um projeto realizado por docentes da disciplina de imunologia da Universidade Federal d...
The aim of this study was to evaluate the profile of dental students and its relationship to anxiety levels. The State-Trait Anxiety Inventory was applied to 207 first- to fifth-year undergraduates enrolled in the dentistry program at the School of Pharmacy, Dentistry and Nursing, Federal University of Ceará, Brazil. Participants were aged 17 to 29 years, and the maiority were women (57.5%). Students had a week...
This study aimed to evaluate the abilities of plant and algae lectins to inhibit planktonic growth and biofilm formation in bacteria and yeasts. Initially, ten lectins were tested on Staphylococcus epidermidis, Staphylococcus aureus, Klebsiella oxytoca, Pseudomonas aeruginosa, Candida albicans, and C. tropicalis at concentrations of 31.25 to 250 μg/mL. The lectins from Cratylia floribunda (CFL), Vatairea macroc...
This study evaluated the effect of derriobtusone A, a flavonoid isolated from Lonchocarpus obtusus, on two important pathogenic bacteria, Staphylococcus aureus and Escherichia coli, as well as its antioxidant activity and toxicity. Planktonic growth assays were performed, and the inhibition of biofilm formation was evaluated. In addition, antioxidant activity was assessed by DPPH radical scavenging assay, ferro...
