- ItemSerum identification of at-risk MASH: The metabolomics-advanced steatohepatitis fibrosis score (MASEF)(2024) Noureddin, Mazen; Truong, Emily; Mayo, Rebeca; Martinez-Arranz, Ibon; Banales, Jesus M.; Minchole, Itziar; Arrese, Marco; Cusi, Kenneth; Arias-Loste, Maria Teresa; Bruha, Radan; Romero-Gomez, Manuel; Iruzubieta, Paula; Aller, Rocio; Ampuero, Javier; Calleja, Jose Luis; Ibanez-Samaniego, Luis; Aspichueta, Patricia; Martin-Duce, Antonio; Kushner, Tatyana; Ortiz, Pablo; Harrison, Stephen A.; Anstee, Quentin M.; Crespo, Javier; Mato, Jose M.; Sanyal, Arun J.Background: Early identification of those with NAFLD activity score >= 4 and significant fibrosis (>= F2) or at-risk metabolic dysfunction-associated steatohepatitis (MASH) is a priority as these patients are at increased risk for disease progression and may benefit from therapies. We developed and validated a highly specific metabolomics-driven score to identify at-risk MASH.
- ItemSynthesis and characterization of processable fluorinated aromatic poly (benzamide imide)s derived from cycloalkane substituted diamines, and their application in a computationally driven synthesis methodology(2019) Pérez Quintana, Germán Miguel; Terraza Inostroza, Claudio; Coll Herrera, Deysma; Ortiz, Pablo; Aguilar Vega, Manuel; González, Darío M.; Tagle Domínguez, Luis Hernán; Tundidor Camba, Alain
- ItemSynthesis and Properties of Poly(imides) and Poly(imides)/Ionic Liquid Composites Bearing a Benzimidazole Moiety(2019) Terraza, Claudio A.; Ortiz, Pablo; Tagle, Luis H.; Perez, German; Saldias, Cesar; Rodriguez-Gonzalez, Fidel E.; Cabrera-Barjas, Gustavo; Catalan, Henry; Tundidor-Camba, Alain; Coll, DeysmaThree new aromatic poly(imides) containing benzimidazole units in the backbone were synthesized and characterized by several spectroscopic techniques. Flexible spacer groups were incorporated into the poly(imides) structure to improve their solubility in organic solvents and their oxidative stabilization. All poly(imides) were thermally stable (T-d5% > 512 degrees C) and had the ability to form dense flexible films. Novel composite films were successfully prepared by loading poly(imide) with ionic liquid ([Bmim]Br) at different concentrations up to 25 wt.%. The resulting materials were characterized according to their morphology and elemental composition (SEM-EDX), water uptake capability, contact angle, and oxidative degradation resistance. Results suggested that poly(imide)/ionic liquid composites would be excellent candidates for future proton conductivity measurements.
