The insides of blood vessels are coated with a layer of saccharide residues know as the endothelial glycocalyx. This layer protects the arterial wall against harmful substances in the bloodstream. The glycocalyx can become damaged, increasing the vulnerability of the endothelium. Carmen Anca Vlahu studies the state of the endothelial glycocalyx on patients with chronic kidney failure. She also describes the peritoneal alterations induced by long term exposure ti high glucose concentration solutions used in dialysis.
