We obtain the class N A of noncommutative cylindric algebras from the class CA of cylindric algebras by weakening the axiom C 4 of commuta-tivity of cylindrifications (to C * 4 , see below, and we obtain N CA from CA by omitting C 4 completely). Some motivation for studying noncommutative cylindric algebras: Noncommutative cylindric algebras (N A's) have(More)
Sinistral, or left-sided, portal hypertension is a rare cause of upper gastrointestinal haemorrhage. There are many causes of sinistral portal hypertension. The primary pathology usually arises in the pancreas and results in compression of the pancreatic vein. This compression causes backpressure in the left portal venous system and subsequent gastric(More)

Patient reported quality of life (QOL) outcomes are important tools for measuring the success of surgical intervention. This is of particular relevance in benign disease when surgery is specifically indicated primarily to treat symptoms and improve QOL. In upper gastrointestinal disease, common conditions such as achalasia, gastro-oeosphageal reflux disease(More)
A solution procedure for the fully coupled Navier–Stokes and Maxwell equations is described. The approach implements a conservative fluid formulation in which the Lorentz body force and Ohmic heating terms are recast as convective terms. This removes explicit sources from the fluid equations, which have previously introduced severe stiffness and demanded a(More)
BACKGROUND Mutations in ATP8B1 gene were identified as a cause of low γ-glutamyltranspeptidase cholestasis with variable phenotype, ranging from Progressive Familial Intrahepatic Cholestasis to Benign Recurrent Intrahepatic Cholestasis. However, only the coding region of ATP8B1 has been described. The aim of this research was to explore the regulatory(More)
BACKGROUND Partial External Biliary Diversion (PEBD) is a surgical intervention to treat children with Progressive Familial Intrahepatic Cholestasis (PFIC) and Alagille syndrome (AGS). PEBD can reduce disease progression, and examining the alterations in biliary lipid composition may be a prognostic factor for outcome. METHODS Biliary lipid composition(More)
