biliary atresia/tyrosine

BACKGROUND Biliary atresia (BA) is an infantile disorder characterized by progressive sclerosing cholangiopathy leading to biliary obstruction. First-line treatment of BA is hepatoportoenterostomy, the prognosis of which is related to age at surgery and to histological variables such as extent of

We measured fasting plasma amino acids in 26 children aged 6 months to 5 years with extrahepatic biliary atresia and cirrhosis and compared them with fasting values in 95 normal control children aged 4 months to 12 years. We found that the cirrhotic children had elevations of total free plasma amino

BACKGROUND Plasma amino acid patterns and the therapeutic benefits of amino acid supplements are not examined well in postoperative patients with biliary atresia (BA). This study aimed to investigate profiles of the amino acid molar ratio, the Fischer molar ratio (FR, valine + leucine +

The absolute and relative concentrations of 16 plasma amino acids in 48 mostly dystrophic infants and children (median of age 1 1/2 years) with extrahepatic biliary atresia and mainly stable preterminal cirrhosis were compared with those of controls. Patient plasma amino acid data were analysed

Urinary Tyrosine Inhibitor (UTI) is produced in the liver and excreted in urine hepatic inflammation, infection or malignancy. We assess the possible implications of UTI in biliary atresia (BA). Liver function was used to divide 34 postoperative BA patients into 2 groups: Group 1 (n=25), anicteric

Jagged-1, one of the five Notch ligands in man, is a membrane-spanning protein made of a large extracellular region and a 125-residue cytoplasmic tail bearing a C-terminal PDZ recognition motif ((1213) RMEYIV(1218) ). Binding of Jagged-1 intracellular region to the PDZ domain of afadin, a protein

OBJECTIVE To investigate the plasma amino acid spectrum in infants more than 1-year-old with neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) in order to identify potential diagnostic markers of NICCD. METHODS Infants less than 1 year of age who had been referred to our hospital

Five patients of cholestatic jaundice and multiple hyperaminoacidemias were uncovered during neonatal mass screening for homocystinuria. All five patients had increased plasma levels of methionine, citrulline, tyrosine, threonine, phenylalanine, lysine and arginine. Compared with those of

BACKGROUND Tyrosinemia is an inherited metabolic disorder characterized by elevated levels of tyrosine and its metabolites in plasma. Without treatment, the disease will progress to hepatic and renal failure, so that without liver transplantation will cause death in less than 10 years of age. So,

Hepcidin is downregulated during progressive cholestasis in biliary atresia, but the mechanism is unknown. To verify whether downregulation of hepcidin is specific to cholestasis irrespective of the patient's age, we first analyzed liver hepcidin mRNA and protein expression in adults with primary

The RNA-binding motif (RRM) gene on Y chromosome (RBMY), encoding a male germ cell-specific RNA-binding protein associated with spermatogenesis, was found inserted by hepatitis B virus (HBV) DNA in one childhood hepatocellular carcinoma (HCC). This study is aimed to explore the oncogenic potential
