The Third Alphabet Of Life: Carbohydrate-Protein Interactions, Kami̇l Seyrek
The Third Alphabet Of Life: Carbohydrate-Protein Interactions, Kami̇l Seyrek
Turkish Journal of Veterinary & Animal Sciences
The structural diversity of oligosaccharides found in glycoconjugates is enormous. This is due to the number of different ways in which sugar monomers may be linked to each other regarding linkage position, anomeric configuration, pyranosidic or furanosidic ring form and chain branching. It has been proposed that these factors contribute to the exquisite potential of oligosaccharides to establish a code system of biological information. The information contained in these structures is decoded by complementary sites present on carbohydrate binding proteins (lectins).

Raw milk was inoculated at 4 different levels with L. monocytogenes serotype 4b (ca. 3, 4, 5, and 6 log cfu ml^{-1} for group 1, 2, 3 and 4 cheeses, respectively) and made into Kashar cheese using the traditional technique. Following dry salting for 10 days at 18 ± 2 ºC, the Kashar cheese was ripened for 20 days at the same temperature and then stored at 5 ± 1 ºC for 3 months. Samples of milk, …

This study was performed to evaluate the feasibility of bone injection gun assisted intraosseous administration of contrast media as an alternative to the intravenous route for urography. Intravenous urographies were obtained in 6 rabbits. Urographic examinations by the intraosseous route were performed in the same animals 48 h later. After adequate anesthesia, the retroauricular vein was punctured for intravenous injection and a bone injection gun was used for intraosseous injections to the distal one-third of the rabbit femur. Direct radiographies of rabbits were obtained following 1200 mg/kg body weight iomeprol (300 mg iodine/ml) administration by both the intravenous and intraosseous …
