background: lectins the multivalent carbohydrate binding proteins are also employed to ascertain differentiation and characterization of the specific cell surface carbohydrate ligands/ receptors of different cell types including spermatozoa and posses novel biomedical importance. objective: sf50 the sialic acid specific lectin was employed on goat cauda epididymal spermatozoa to investigate its...

altered glycosylation of proteins in cancer cells is one of the main processes responsible for anaplasia, invasion and metastatic potential of neoplastic cells. lectins are nonimmunogenetic compounds which specifically detect certain terminal sugars of glycoconjugates. the aim of the present study was to identify the n-acetylgalactosamine (galnac) containing glycoconjugates in cancer cells in a...

examples of inter- and intramolecular direct co-functioning of lectins and enzymes are summarized. the data indicate importance of lectin-enzyme relationships in molecular and clinical microbiology and medical biotechnology. lectin-enzyme relationships have extended prospects in medicine and biotechnology.

one of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. the four pattern recognition molecules that have been identified till now are mannose binding lectin (mbl), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. mbl ...

Alginates are natural anionic polyelectrolytes investigated in various biomedical applications, such as drug delivery, tissue engineering, and 3D bioprinting. Functionalization of alginates is one possible way to provide a broad range requirements for those applications. A techniques, including esterification, amidation, acetylation, phosphorylation, sulfation, graft copolymerization, oxidation...

during early neurogenesis, the floor plate plays an essential role(s) in the differentiation of the ventral portion of neural tube. in this study, we detected the specific distribution of unique glycoconjugate during the floor plate differentiation. formalin fixed paraffin sections of balb/c mice (10-14 embryonic days) were processed for histochemical studies using horseradish peroxidase-labell...

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...

results in this study, 45 (13.4 %) urine samples were positive for candida species (17 males and 28 females). the most common isolated yeast was candida albicans (34%), followed by c. glabrata (32.1%), c. tropicalis (9.4%), other candida species (22.6%), and rhodotorula species (1.9%). the mean serum levels of mbl were 0.85 ± 0.01 ng/ml and 1.02 ± 0.03 ng/ml among candiduric patients and contro...

background: ‍‍cryopreservation has some detrimental impacts on sperms surface molecules. modification of the sperm surface molecules can affect on fertility rate. one of the important surface molecules are glycoconjugates. objective: the objective of this study was to evaluate the changes of content of the glycocalyx after standard cryopreservation procedure. materials and methods: forty five h...
