Modulation of hyaluronan in the migratory pathway of mouse primordial germ cells
(Springer, 2002-03-01)
In the present report we followed the distribution of hyaluronan during the phases of separation, migration, and colonization of the primordial germ cell migratory process. Hyaluronan was detected by the use of two ...
APPEARANCE and FATE of A BETA-GALACTANASE, ALPHA,BETA-GALACTOSIDASES, HEPARAN-SULFATE and CHONDROITIN SULFATE DEGRADING ENZYMES DURING DEVELOPMENT of the MOLLUSK POMACEA SP
(Elsevier B.V., 1994-08-18)
The characterization and properties of a beta-galactanase and alpha- and beta-galactosidases as well as heparan sulfate and chondroitin sulfate degrading enzymes which appear during the 15 days of the embryonic development ...
Fucan inhibits Chinese hamster ovary cell (CHO) adhesion to fibronectin by binding to the extracellular matrix
(Georg Thieme Verlag Kg, 2005-07-01)
In recent years, sulfated fucans have emerged as an important class of natural biopolymers. in this study, the anti-adhesive activity of a fucan from the brown seaweed Spatoglossum schroederi was analyzed using tumorigenic ...
Web-based learning in undergraduate medical education: development and assessment of an online course on experimental surgery
(Elsevier B.V., 2004-09-01)
In order to increase the number of practical and discussion classes offered to students in the traditional-curriculum scenario, while decreasing the lecture-based ones and to create an online community to share knowledge ...
Effect of bradykinin and PMA on the synthesis of proteoglycans during the cell cycle of endothelial cells in culture
(Elsevier B.V., 2003-03-01)
Bradykinin (BK) and phorbol 12-myristate-13-acetate (PMA) were used in the present work to study the biosynthesis of proteoglycans (PG) during the cell cycle of endothelial cells. PMA, an activator of PKC, stimulated the ...
STRUCTURE of HEPARAN-SULFATE FROM the FRESH-WATER MOLLUSK ANOMANTIDAE SP - SEQUENCING of ITS DISACCHARIDE UNITS
(Elsevier B.V., 1993-09-01)
1. the disaccharide sequences of a heparan sulfate isolated from Anomantidae sp. was determined with the aid of heparitinase I, heparitinase II from Flavobacterium heparinum, mollusc beta-glucuronidase and alpha-N-acetyl ...
Identification and partial characterisation of hyaluronidases in Lonomia obliqua venom
(Elsevier B.V., 2005-03-15)
By studying Lonomia obliqua (caterpillar) venom we were able to detect a lytic activity on purified hyaluronic acid. the venom hydrolyses purified chondroitin sulphate, but was unable to degrade either heparan sulphate or ...
EJ-ras oncogene transfection of endothelial cells upregulates the expression of syndecan-4 and downregulates heparan sulfate sulfotransferases and epimerase
(Elsevier B.V., 2006-10-01)
The EC rabbit endothelial cell line was transfected with the EJ-ras oncogene (EJ-ras EC). EJ-ras EC cells display over expression of the Ras oncogene, morphological changes and deregulation of the cell cycle, becoming more ...
Comparison of practical methods for urinary glycosaminoglycans and serum hyaluronan with clinical activity scores in patients with Graves' ophthalmopathy
(Blackwell Publishing Ltd, 2004-06-01)
OBJECTIVE Immunosuppressive treatment of Graves' opthalmopathy (GO) should be restricted to patients with active eye disease, but assessing disease activity is difficult. Several methods to evaluate GO activity have been ...
Effect of brown spider venom on basement membrane structures
(Kluwer Academic Publ, 2000-07-01)
Loxoscelism or necrotic arachnidism are terms used to describe lesions and reactions induced by bites (envenomation) from spiders of the genus Loxosceles. Envenomation has been reported to provoke dermonecrosis and haemorrhage ...
