One of her favorite topics is the effect of hemodialysis procedure, especially the administration of different heparins, on endothelial derived markers such as TF / TFPI regulation of extrinsic blood coagulation, activin A / follistatin / hepatocyte growth factor pleiotropic system as well as on some growth factors playing a crucial role in cell proliferation. All the above markers take part in the pathogenesis of cardiovascular complications in patients with chronic renal failure.
