Novel magnetic resonance KTRANS measurement of blood-brain barrier permeability correlated with covert HE

Chaganti J, Zeng G, Tun N, Lockart I, Abdelshaheed C, Cysique L, Montagnese S, Brew BJ, Danta M HE Hepatol Commun Background: Using dynamic contrast-enhanced (DCE) MR perfusion and MR spectroscopy this study aimed to characterize the blood-brain barrier permeability and metabolite changes in patients with cirrhosis and without covert HE. Methods: Covert HE was defined using […]

Prognosis and Survival Modelling in Cirrhosis Using Parenclitic Networks

Zhang H, Oyelade T, Moore KP, Montagnese S, Mani AR Front Netw Physiol Background: Liver cirrhosis involves multiple organ systems and has a high mortality. A network approach to complex diseases often reveals the collective system behaviours and intrinsic interactions between organ systems. However, mapping the functional connectivity for each individual patient has been challenging due […]

Circadian rhythms and the liver

Costa R, Mangini C, Domenie E, Zarantonello L, Montagnese S Liver Int This narrative review briefly describes the mammalian circadian timing system, the specific features of the liver clock, also by comparison with other peripheral clocks, the role of the liver clock in the preparation to food intake, and its relationship with energy metabolism. It […]

Hyperammonaemia disrupts daily rhythms reversibly by elevating glutamate in the central circadian pacemaker

Granados-Fuentes D, Cho K, Patti GJ, Costa R, Herzog E D, Montagnese S Liver Int Patients with cirrhosis exhibit features of circadian disruption. Hyperammonaemia has been suggested to impair both homeostatic and circadian sleep regulation. Here, we tested if hyperammonaemia directly disrupts circadian rhythm generation in the central pacemaker, the suprachiasmatic nuclei (SCN) of the […]
