introduction: studies have shown that opiates cause disorders in fertilization and accessory reproductive glands in animals. on the other hand studies have shown important role of glycoconjugates in sperm epididymal maturation. lectins can detect glycoconjugates with specific terminal glucose molecules. therefore this study was conducted to assess the possible effects of opiates on these import...

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...

objective: the aim of the present study was to evaluate the structure and distribution of glycoconjugates during molar tooth germ development in mice materials and methods: sixteen tooth germs were obtained from balb/c mice embryos 15 to 18 days post-gestation and fixed in 10% formalin. after routine tissue processing, 5 μm sections were cut and stained with bsa1-b4 and pna using the lectin his...

introduction: glycoconjugates are molecules with a carbohydrate bounded to proteins. the terminal sugars of glycoconjugates are specific identified by lectins. glycoconjugates play an important role in various developmental processes. this study examines the developmental changes in certain glycoconjugates during the development of meckel's cartilage through lectin histochemistry. materials and...

The synthesis of complex C-glycoconjugates is presented here using a key directed nickel-catalyzed C?H alkynylation step. Thanks to bidentate amidoquinoline-type directing group, the insertion diverse alkynyl moieties onto pseudo-anomeric position glycal substrates was performed on ten examples in moderate good yields. These platforms were used as starting click reaction with azides form origin...

Glycoconjugates and their programmed changes during the course of development in the cell-surface as well as in the extracellular matrix, are known to affect cell differentiation, cellular interaction and other developmental phenomena during embryogenesis. The purpose of this study was to localize N-acetylgalactosamin as well as fucose-containing glycoconjugates in situ during thymus developmen...

Iron and eosinophilic, argyrophilic spheroid structures of glycoconjugates are observed in the pallido-nigral system of human and nonhuman primates. In the present study, we map the localization and distribution of ferritin and hemosiderin and their relation to neutral and acidic (sulphated and carboxylated) glycoconjugates in human globus pallidus. We investigated tissues of human globus palli...

Boron-rich dendritic glycoconjugates of ortho -carborane clusters containing three to six peripheral hydrophilic glucose moieties have been found be promising anticancer agents.
