Tivadar Tulassay is a medical expert. His research focuses on the post‐natal adaptation and regulation of water and electrolytes, and on hypertension in children. The gynaecologist and paediatrician also investigates kidney development in premature babies.
Tivadar Tulassay was the first to link the cause of kidney failure in newborns to respiratory failure. In the 1980s he described the regulatory role of the atrial natriuretic peptide (ANP) and the changes in the body’s intravascular space related to this, as well as in human ANP activity. In the late 1990s he focused on experiments with human red blood cells and their activity changes in transport proteins such as in the case of insulin‐dependent diabetes or mucoviscidosis.
