Polymorphisms −374 T/A and −429 T/C of the receptor for advanced glycation end-products (RAGE) and serum levels of RAGE (sRAGE) are not associated with metabolic syndrome
; ; ; ; Rojas, Armando
; (2023)
RAGE is a multi-ligand transmembrane glycoprotein that promotes biological signals associated with inflammatory responses and degenerative diseases. sRAGE is a soluble variant that has been proposed as an inhibitor of RAGE ...

Coalition formation problems with externalities
(2023)We study coalition formation problems with externalities. We prove that, if expectations are not prudent a stable coalitions structure may fail to exist. Under prudent expectations a stable and efficient coalition structure ...
