1. Acrylamide reduces plasma antioxidant vitamin levels in rats due to increased oxidative damage
RESUMO Objetivo A acrilamida é um químico potencialmente neurotóxico e carcinogênico, sendo naturalmente criada durante o processo de aquecimento de alimentos ricos em carboidratos, como batatas fritas e cereais matinais. Dado que o composto pode ser ingerido através do consumo de alimentos, o presente trabalho teve por objetivo investigar o seu efeito

2. Evaluation of Serum Levels of Inflammation, Fibrinolysis and Oxidative Stress Markers in Coronary Artery Disease Prediction: A Cross-Sectional Study
Resumo Fundamento: A doença arterial coronariana (DAC) tem sido há muito reconhecida como um problema de saúde global. Inflamação, fibrinólise e estresse oxidativo desempenham um papel importante no acometimento das placas, levando à DAC. Os marcadores que refletem esse mecanismo fisiopatológico podem ter valor prognóstico. Objetivo: Estimar as co

3. Scedosporium apiospermum, Scedosporium aurantiacum, Scedosporium minutisporum and Lomentospora prolificans: a comparative study of surface molecules produced by conidial and germinated conidial cells
BACKGROUND Scedosporium/Lomentospora species are opportunistic mould pathogens, presenting notable antifungal resistance. OBJECTIVES/METHODS We analysed the conidia and germinated conidia of S. apiospermum (Sap), S. aurantiacum (Sau), S. minutisporum (Smi) and L. prolificans (Lpr) by scanning electron microscopy and exposition of surface molecules by fluor

4. Effect of fluoride on salivary immunoglobulins and sialic acid
Summary Objective: The aim of our study was to evaluate the effect of fluoride on salivary immunoglobulin and sialic acid levels in children with dental fluorosis and healthy teeth who live in places with high fluoride concentration in drinking water. Method: Fifty-one (51) healthy children between 6 and 12 years old with no caries were randomly selected f

5. Lectin activity in mycelial extracts of Fusarium species
ABSTRACT Lectins are non-immunogenic carbohydrate-recognizing proteins that bind to glycoproteins, glycolipids, or polysaccharides with high affinity and exhibit remarkable ability to agglutinate erythrocytes and other cells. In the present study, ten Fusarium species previously not explored for lectins were screened for the presence of lectin activity. Myce

6. Sperm and Egg Jelly Coat from Sea Urchin Lytechinus variegatus Collected in Rio de Janeiro Contain Distinct Sialic Acid-Rich Polysaccharides
This work found the occurrence of a distinct sialic acid-rich polysaccharide in the sperm surface of the sea urchin Lytechinus variegatus, which differed significantly from a similar molecule found in the egg jelly. The sperm polysaccharide extracted by protease digestion was purified using anion exchange chromatography and characterized using agarose gel el

7. Prevalence of Group B Streptococcus serotypes III and V in pregnant women of Rio de Janeiro, Brazil
GBS serotypes III and V were the most prevalent in pregnant women and exhibited resistance to tetracycline, clindamycin and sulfamethoxazole/trimethoprim. Serotype III showed high sialic acid content and PFGE analysis discerned 33 heterogeneous profiles. Phenotypic and genotypic characterization could be relevant to control GBS infections unaffected by intra

8. Fases sólidas luminescentes contendo íons lantanídeos : uma proposta para determinação de ácido siálico.
The organofunctionalized silica was used as the solid support in the study of photophysical properties of lanthanides, in particular the Eu (III) ions, which functions as structural probe has been thoroughly discussed seeking new technological applications. In this study, were synthesized two novel organofunctionalized silica matrices and new lanthanide comp

9. Modulation of ROS production in human leukocytes by ganglioside micelles
Recent studies have reported that exogenous gangliosides, the sialic acid-containing glycosphingolipids, are able to modulate many cellular functions. We examined the effect of micelles of mono- and trisialoganglioside GM1 and GT1b on the production of reactive oxygen species by stimulated human polymorphonuclear neutrophils using different spectroscopic met

10. Comparative study of the Fc region from murine IgG1 anaphylactic and non anaphylactic antibodies / Estudo comparativo da região Fc de anticorpos IgG1 murinos anafiláticos e não-anafiláticos
It is well established that the glycosylation process is essential for the structural conformation and effector function of the antibodies. However, it is quite clear how differences in the carbohydrates attached to the antibodies may interfere with their biological activities. It was previously reported that murine IgG1 antibodies can be divided into anaphy

11. Structure-function analysis of two variants of mumps virus hemagglutinin-neuraminidase protein
A point mutation from guanine (G) to adenine (A) at nucleotide position 1081 in the hemagglutinin-neuraminidase (HN) gene has been associated with neurovirulence of Urabe AM9 mumps virus vaccine. This mutation corresponds to a glutamic acid (E) to lysine (K) change at position 335 in the HN glycoprotein. We have experimentally demonstrated that two variants

12. Association between dental-oral health in young adults and salivary glutathione, lipid peroxidation and sialic acid levels and carbonic anhydrase activity
The aim of the present study was to evaluate the relationship between salivary oxidative stress and dental-oral health. Healthy young adults, matched for gender and age, with (N = 21, 10 men, mean age: 20.3 ± 1 years) and without (N = 16, 8 men, mean age: 21.2 ± 1.8 years) caries were included in this study. The World Health Organization (WHO) caries diagn
