1. Serodiagnosis of human neurocysticercosis using antigenic components of Taenia solium metacestodes derived from the unbound fraction from jacalin affinity chromatography
The aim of the present study was to analyse Taenia solium metacestode antigens that were derived from the unbound fraction of jacalin affinity chromatography and subsequent tert-octylphenoxy poly (oxyethylene) ethanol Triton X-114 (TX-114) partitioning in the diagnosis of human neurocysticercosis (NCC). Immunoassays were designed to detect T. solium-specifi

2. Estudo e desenvolvimento de nanocompósitos contendo nanopartículas de ouro conjugadas com biomoléculas: síntese e aplicações em nanomedicina / Study and development of nanocomposites containing gold nanoparticles and biomolecules: synthesis and application in nanomedicine
A convergência entre a biotecnologia e a nanotecnologia tem levado ao desenvolvimento de novos nanobiocompósitos híbridos com funções sinérgicas que incorporam as propriedades de reconhecimento dos biomateriais com as propriedades eletrônicas, ópticas e catalíticas únicas das nanopartículas. Apesar do recente desenvolvimento na síntese de nanobio

3. Characterization and application of thin film of carboxymehtylcellulose acetate butyrate / Caracterização e aplicação de filmes finos de acetato butirato carboximetil celulose
The effect of ethyl acetate and acetone on the solution behavior of cellulose acetate butyrate (CAB) and carboxymehtylcellulose acetate butyrate (CMCAB) and on the characteristics of films obtained either by spin coating or adsorption was investigated. Viscosity and small angle X-ray scattering (SAXS) measurements showed that ethyl acetate is a better solven

4. Avaliação de frações antigênicas da forma metacestódea de Taenia saginata no imunodiagnóstico da neurocisticercose humana
A utilização de metacestódeos de Taenia saginata como antígeno alternativo constitui uma importante ferramenta no sorodiagnóstico da neurocisticercose humana (NC). A reatividade cruzada com indivíduos infectados por Echinococcus granulosus é comum em antígenos homólogos e heterólogos, podendo ser evitada com diferentes métodos de purificação. O

5. Screening of lectins from South American plants used as affinity ligands to purify rhEPO
Two groups of isoforms of rhEPO, at a concentration of 300 µg/ml, were tested as putative inhibitors of the lectinic hemagglutination reaction in order to obtain affinity ligand(s) for hormone purification: groups I (pI: 3.80; 3.89; 3.95; 4.07, 4.15 and 4.26) and groups II (pI: 4.15, 4.26; 4.38; 4.51; 4.72 and 4.93) Crude extracts from the vegetable materia

6. Influencia das lectinas PHA, de Phaseolus vulgaris, WGA, de germe de trigo e jacalina, de Artocarpus integrifolia, no processo de reparação tecidual da pele de ratos
Wound healing is a complex and dynamic process, characterized by the integrated actions of different cells. Lectins are glycoproteins which can present several biological activities. Many of lectin activities may contribute to repair including increased production of cytokines, and activation of inflammatory cells and fibroblasts. The purpose of this work wa

7. Caracterização morfologica e funcional de exsudato peritoneal induzido pela jacalina em camundongos
In this work we studied the peritoneal exsudate induced by the lectin jacalin. We observed that jacalin induced large numbers of Polymorphonuclear cells (Neutrophils) within a 48 h period. After this time, the number of neutrophils decreased and the number of mononuclear cells increased. Following injection with jacalin, the number of mononuclear cells reach

8. The lectin Jacalin induces human B-lymphocyte apoptosis through glycosylation-dependent interaction with CD45
It has been well established that CD45 is a key receptor-type protein tyrosine phosphatase (PTPase) regulating Src-family protein tyrosine kinase (Src-PTK) in T and B lymphocytes. However, precisely how CD45 exerts its effect in these lymphocytes remains controversial. We recently reported that Jacalin, an α-O-glycoside of the disaccharide Thomsen–Frieden

9. Two Distinct Jacalin-Related Lectins with a Different Specificity and Subcellular Location Are Major Vegetative Storage Proteins in the Bark of the Black Mulberry Tree1
Using a combination of protein isolation/characterization and molecular cloning, we have demonstrated that the bark of the black mulberry tree (Morus nigra) accumulates large quantities of a galactose-specific (MornigaG) and a mannose (Man)-specific (MornigaM) jacalin-related lectin. MornigaG resembles jacalin with respect to its molecular structure, specifi

10. Opsonic effect of jacalin and human immunoglobulin A on type II group B streptococci.
This study examined the effect of immunoglobulin A (IgA) and the IgA-binding lectin jacalin on the phagocytosis of type II group B streptococci (GBS). Strains possessing the trypsin-sensitive and trypsin-resistant components of the c protein (II/c) and type II GBS lacking the c protein (II) were examined by radiolabeled bacterial uptake, bactericidal assays,

11. Cloning of the Arabidopsis RTM1 gene, which controls restriction of long-distance movement of tobacco etch virus
The locus RTM1 is necessary for restriction of long-distance movement of tobacco etch virus in Arabidopsis thaliana without causing a hypersensitive response or inducing systemic acquired resistance. The RTM1 gene was isolated by map-based cloning. The deduced gene product is similar to the α-chain of the Artocarpus integrifolia lectin, jacalin, and t

12. Increased levels of serum IgA as IgA1 monomers in ankylosing spondylitis.
The various subsets of serum IgA were determined in 43 patients with ankylosing spondylitis to investigate the putative mucosal origin of increased IgA concentrations in this disease. Total IgA was shown to be increased and weakly correlated with the erythrocyte sedimentation rate (ESR). In contrast, although the mean concentration (but not the median) of se
