How many proteins are hidden in the fruits? This is the question that Miguel Aranda, researcher from the Kidney Physiopathology group at VHIR, asked to the visitors of the "http://lameva.barcelona.cat/novum/ca/" NOVUM Barcelona Science Festival.On Sunday morning, many children participated with their families in his workshop, located at the Plaça de les Glòries, in Barcelona, in order to know the role of the proteins in fruits and humans. The aim of Miguel’s workshop was to explain the role of proteins and why is useful to count them. In his lab, researchers study pathologies such as Dent’s disease that is characterized by the loss of proteins through the urine and leads to chronic kidney failure. The Barcelona Science Festival, which in the past editions was located at the Parc de la Ciutadella, was organized by the Barcelona city council with the aim to promote the activity carried out by research centers and scientific associations from the city.
