The aim of the present study was to evaluate qualitative changes in the glycoconjugate expression in human gastric tissue of positive and negative patients for Helicobacter pylori, through lectins: Wheat Germ Agglutinin (WGA) and Concanavalin A (Con A). The lectins recognized differently the glycoconjugates in the superficial mucous layer at the gastric tissues. The results suggest a significan...

The present study has examined the glycoconjugate profile in plasma and erythrocyte membranes of 24 adult male gastric cancer patients and an equal number of age and sex-matched controls. Protein-bound hexose, hexosamine and sialic acid were significantly increased in plasma and erythrocytes of gastric cancer patients compared to controls. Elevation of glycoconjugates in circulation is suggeste...

Glycoconjugates involved in many functions are produced by cell types. This study aimed to investigate the glycoconjugate expression Oscar fish (Astronotus ocellatus) gills using five horseradish peroxidase-conjugated lectins. revealed that gill epithelial cells react with Canavalia ensiformis agglutinin (Con A) and Arachis hypogaea (PNA). Strong reaction Con A was seen of primary lamellae. Epi...

In this study, primary and immortalized bovine intestinal epithelial cells (BIECs) were characterized for the expression of surface carbohydrate moieties. Primary BIEC-c4 showed staining greater than 90 % 16 lectins but less 50 four lectins. Immortalized BIECs significantly different lectin binding profile few compared to cells. studied infectivity E. coli, Salmonella enterica, rotavirus, coron...

Smoke taint has become a prominent issue for the global wine industry as climate change continues to impact length and extremity of fire seasons around world. When grapevines are exposed smoke, their leaves fruit can adsorb volatile smoke compounds (for example, phenols such guaiacol, 4-methylguaiacol, o-, m- p-cresol, syringol), which initially be detected in free (aglycone) forms but rapidly ...
