1. Polimorfismo do gene da lectina ligante de manose e seu efeito em desfechos de curto prazo em bebês prematuros
Resumo Objetivo: A lectina ligante de manose (MBL, do inglês mannose-binding lectin), que pertence à família das colectinas, é um reagente de fase aguda que ativa o sistema complemento. Este estudo teve como objetivo investigar o efeito do polimorfismo do gene MBL2 em desfechos de curto prazo em prematuros. Método: Este estudo prospectivo incluiu cria

2. Effect of Pesticide Addition Sequence on the Preparation of Phytosanitary Spray Solutions
RESUMO: A adição de adjuvantes às caldas herbicidas visa preservar ou aumentar o efeito biológico do tratamento, porém é comumente realizada sem conhecimento das interações físico-químicas entre os produtos. Assim, objetivou-se neste trabalho avaliar os efeitos sobre a tensão superficial e o ângulo de contato decorrentes de diferentes sequências

3. Inhibitory effect of Lonchocarpus araripensis lectin in rat acute models of inflammation
Abstract: Dalbergieae tribe lectins, possessing binding affinity for galactose and mannose, present inflammatory and nociceptive effects, while those for N-acetylglucosamine are anti-inflammatory. Since the anti-inflammatory effect of the seed lectin of L. araripensis (LAL) had been already demonstrated in mice, this effect was presently evaluated in rat mod

4. Association between MBL2 haplotypes and dengue severity in children from Rio de Janeiro, Brazil
BACKGROUND Dengue is an arthropod-borne viral disease with a majority of asymptomatic individuals and clinical manifestations varying from mild fever to severe and potentially lethal forms. An increasing number of genetic studies have outlined the association between host genetic variations and dengue severity. Genes associated to viral recognition and ent

5. Subproteome of Lachesis muta rhombeata venom and preliminary studies on LmrSP-4, a novel snake venom serine proteinase
Abstract Background: Lachesis muta rhombeata is one of the venomous snakes of medical importance in Brazil whose envenoming is characterized by local and systemic effects which may produce even shock and death. Its venom is mainly comprised of serine and metalloproteinases, phospholipases A2 and bradykinin-potentiating peptides. Based on a previously report

6. Mannose-Binding Lectin 2 (MBL2) combined genotypes deficiency is associated with susceptibility for Oral Lichen Planus
Abstract Oral Lichen Planus (OLP) is an oral inflammatory condition, mediated by host immune system reaction, presenting basal membrane damages with inflammatory lesions in the mouth and/or skin. In this study, the role of functional polymorphisms in the MBL2 gene, encoding for Mannose-Binding Protein C (MBP-C), a member of the innate immune response and an

7. Enzyme activity and biochemical changes during production of Lentinula edodes (Berk.) Pegler
Abstract Shiitake is an important edible and medicinal mushroom cultivated worldwide. Its cultivation involves a complex process of browning that precedes the primordia initiation. The present work through the evaluation of enzymes, lectin and β-glucan during the cultivation cycle of Lentinula edodes, the degradation of cellulose, hemicellulose and lignin,

9. Complement system contributes to modulate the infectivity of susceptible TcI strains of Trypanosoma cruzi
BACKGROUND Trypanosoma cruzi is a protozoan parasite and an etiological agent of Chagas disease. There is a wide variability in the clinical outcome of its infection, ranging from asymptomatic individuals to those with chronic fatal mega syndromes. Both parasite and host factors, as well as their interplay, are thought to be involved in the process. OBJECT

10. Detection, purification and characterization of a lectin from freshwater green algae Spirogyra spp.
ABSTRACT Freshwater algae are rich sources of structurally biologically active metabolites, such as fatty acids, steroids, carotenoids and polysaccharides. Among these metabolites, lectins stand out. Lectins are proteins or glycoproteins of non-immune origin which bind to carbohydrates or glycoconjugates, without changing ligand structure. Many studies have

11. Combined genotypes of the MBL2 gene related to low mannose-binding lectin levels are associated with vaso-occlusive events in children with sickle cell anemia
Abstract Sickle cell anemia (SCA) presents heterogenous clinical manifestations that cannot be explained solely by alterations to hemoglobin (Hb); other components such as endothelial adhesion, thrombosis and inflammation may be involved. The mannose-binding lectin (MBL) has an important role in innate immunity and inflammatory diseases. In this report, we d

12. Endogenous phospholipase A2 inhibitors in snakes: a brief overview
Abstract The blood plasma of numerous snake species naturally comprises endogenous phospholipase A2 inhibitors, which primarily neutralize toxic phospholipases A2 that may eventually reach their circulation. This inhibitor type is generally known as snake blood phospholipase A2 inhibitors (sbPLIs). Most, if not all sbPLIs are oligomeric glycosylated proteins
