Copper–Collagen Interactions Regulate the Mechanical and Invasive Properties of Tumor Spheroids
Advanced Healthcare Materials, EarlyView.Ionic copper is investigated as a modulator of tumor spheroid growth and invasiveness in a 3D microfluidic glioblastoma model. Copper exposure alters metabolic activity, cytoskeletal organization, protrusion dynamics, and EMT‐related phenotypes in a dose‐ and timing‐dependent manner, revealing how copper bioavailability shapes tumor aggressiveness ...

Escuela comprehensiva o escuela selectiva
Vivat Academia. Revista de Comunicación, 2008 La escuela comprehensiva reúne a chicos con distintas capacidades, talentos y trayectorias y los escolariza en el mismo aula. El gremio docente, en general, prefiere la escuela comprehensiva a la selectiva. Ésta es considerada segregadora y germen de desigualdades y rencor social.
