The interactions of glycosaminoglycans (GAGs) with proteins underlie a wide range of important biological processes. However, the study of such binding reactions has been hampered by the lack of a simple frontline analysis technique. Previously, we have reported that cold plasma polymerization can be used to coat microtiter plate surfaces with allyl amine to which GAGs (e.g., heparin) can be no...

Glycosaminoglycans (GAGs) take part in numerous biological processes by binding to protein molecules and functionally regulating protein-ligand interactions; therefore, molecular interactions of GAGs have been studied by several methods, including surface plasmon resonance, enzyme-linked immunosorbent assays (ELISAs), and GAG microarrays. To achieve rapid, sensitive, and high-throughput screeni...

The glycosaminoglycan chondroitin sulfate is significantly increased in the peritumoral stroma of prostate tumors compared with normal stroma and is an independent predictor of prostate-specific antigen (PSA) relapse following radical prostatectomy. In this study, we determined whether specific alterations in the sulfation pattern of glycosaminoglycan chains in clinically organ-confined prostat...

Osteoarthritis (OA) is a common group of disabling joint disorders for which there are limited pharmacological therapies to alter disease progression. Zoledronate, one of several bisphosphonates found to modulate joint changes in animal OA models, may have a disease-modifying role, and potential mechanisms of action include effects on cartilage and/or subchondral bone. In OA cartilage, loss of ...

The present study aims at providing a detailed description of the histology, as well as the first histochemical characterization, of the secretory cells of the epidermis, pharynx, and copulatory organs of Choeradoplana iheringi, in order to give further support to studies on the physiology of these organs. The secretory cells are distinguished on the basis of secretion morphology and its staini...
