The Principle of Symmetric Criticality in General Relativity [PDF]

, 2001
We consider a version of Palais' Principle of Symmetric Criticality (PSC) that is applicable to the Lie symmetry reduction of Lagrangian field theories. PSC asserts that, given a group action, for any group-invariant Lagrangian the equations obtained by ...

Serum micrornas as novel biomarkers for primary sclerosing cholangitis and cholangiocarcinoma [PDF]

, 2016
The diagnosis of primary sclerosing cholangitis (PSC) is difficult due to the lack of sensitive and specific biomarkers, as is the early diagnosis of cholangiocarcinoma (CC), a complication of PSC.

Polygenic risk score predicts risk of primary sclerosing cholangitis in inflammatory bowel disease

BMJ Open Gastroenterology, 2023
Background Forty distinct primary sclerosing cholangitis (PSC) genomic loci have been identified through multiancestry meta-analyses. The polygenic risk score (PRS) could serve as a promising tool to discover unique disease behaviour, like PSC ...

The natural history of primary sclerosing cholangitis in 781 children. A multicenter, international collaboration [PDF]

, 2017
There are limited data on the natural history of primary sclerosing cholangitis (PSC) in children. We aimed to describe the disease characteristics and long-term outcomes of pediatric PSC.
