Allied to the problem of gastrointestinal parasites, especially Haemochus contortus, the use of lectins of plant origin has contributed to the research of alternative anthelmintics. The nematicidal effect of a water soluble Moringa oleifera lectin (WSMoL) was investigated in an experimental model with H. contortus infected Wistar rodents. Three con...
Article
Haemonchus contortus is a hematophagous parasite that causes damage to ruminant production worldwide. This study reported the in vitro nematicidal effect of a lectin preparation (LP) isolated from Artocarpus heterophyllus seeds on larvae and adults of H. contortus. The protein extraction was in phosphate-buffered saline followed by protein precipit...
Article
Haemonchus contortus is a hematophagous parasite causing damage to the production of ruminant animals throughout the world. This study evaluated the in vitro effect of proteins from Moringa oleifera (WSMoL - Water Soluble M. oleifera Lectin and cMoL - coagulant M. oleifera Lectin) on the motility of infective larvae and adult male and female worms...

O estudo teve como objetivo elucidar o panorama evolutivo da Rede Nordeste de Biotecnologia (RENORBIO), desde a sua criação em 2006 até o período de 2015. Para tanto, utilizou-se como metodologia a pesquisa quantitativa e os métodos investigativo exploratório e descritivo. O estudo mostrou que a RENORBIO é composta por 35 instituições de ensino e p...

Gastrointestinal nematodes are the major cause of animal diseases, and the indiscriminate use of synthetic anthelmintic contributes to the development of drug resistance. Natural bioproducts are noteworthy since they have proved to be promising for alternative antiparasitic therapies. This study evaluated the in vitro effect of WSMoL (water soluble...

... M. oleifera is a well-known plant in Nigeria, where it is being exploited for different purposes [22,23]. Isolation of lectins has been reported from distinct parts of the M. oleifera plant, with diverse activities attributed to these quintessential proteins [24][25][26]. This study, therefore, investigated the hemolytic (membrane-perturbing) activity of a purified lectin from M. oleifera seeds, which could be exploited as a protein-based intracellular drug delivery agent. ...
... Para compreendermos tal cenário, preliminarmente, direcionamos nosso olhar para a formação inicial. Encontramos na literatura pesquisas que sinalizam para a ausência de discussões sobre AC e Ciência, Tecnologia e Sociedade (CTS) na formação inicial de professores de Ciências do Ensino Fundamental, além de fragilidades relacionadas a uma formação fragmentada, descontextualizada e conteudista (Bertagna-Rocha, 2013;Azevedo et al., 2013;Briccia & Carvalho, 2016;Machado et al., 2019;Medeiros & Medeiros, 2020). ...
... Among scientific studies on this topic, we observed the absence of research on the actors and their scientific and technological production, from the perspective of SNA. The studies found address the characteristics of RENORBIO, by describing the number of articles, number of patents, and participating laboratories (SOLA; QUINTELLA, 2011;SILVA et al., 2016;MEDEIROS;RONDON, 2018). However, this study sought to understand the profile of the selected Network and, to do this, it was necessary to study it by considering the actors as co-responsible for its products, and these are the results of their relationships' flows, whether professional or personal. ...
... Lectins are of no doubt one of the most versatile molecules that have been under the research focus. This is partly due to their in-vitro effectiveness in suppressing or modulating activities of viruses [83][84][85], bacteria, fungi (the references cited herein), and parasites [86,87]. A promising combined therapy of antibiotics and lectin, often known as a "drug cocktail" to enhance or reactivate the action of the antibiotics, is currently finding much interest. ...
