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...

objective(s) the aim of this study was to investigate glycoconjugates distribution patterns as well as their changes during the course of pituitary portal vasculogenesis and angiogenesis. materials and methods formalin fixed paraffin sections of 10 to 20 days of sprague dawly rat fetuses were processed for histochemical studies using four different horseradish peroxidase (hrp) conjugated lectin...

Aberrant sperm phenotypes coincide with the expression of unique sperm surface determinants that can be probed by objective, biomarker-based semen analysis and targeted as ligands for semen purification. This study evaluated a nanoparticle-based magnetic purification method that removes defective spermatozoa (∼30% of sample) from bull semen and improves sperm sample viability and fertilizing ab...

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...

Introduction: One of the most common reasons of infertility is un-ovulatory period. Hormone therapy is the most common treatments of this type of infertility. Gonadotropins may exert toxic effects on the molecular organization of uterine surface, such as glycoconjugates. Glycoconjugates are the most important components of the uterine and trophoblast surface playing an important role in embryo ...

Terminal saccharide sequences in rat photoreceptor cell surface glycoconjugates were characterized. Lectin cytochemistry and electron microscopy were used for preembedding cytochemical localization of surface carbohydrates. Neuraminidase digestion was employed for the exposure of penultimate saccharides in sialoglycoconjugates. Isolated rat retinas were incubated with ferritin-labeled wheat ger...
