BACKGROUND Severe anoxic brain injury can lead to prolonged episodes of status dystonicus. Sustained dystonia can result in skeletal muscle breakdown and elevation of serum transaminases, which can initially be confused with polypharmacy-related hepatotoxicity or an underlying metabolic condition. PATIENT We present a 19-month-old boy who sustained a severe anoxic brain injury in the setting ...

background most therapeutic interventions in acute phase of viral hepatitis b patients are conservative. prostaglandins have absorbed many scientists' attention for improving these patients condition, therefore, the present study was designed to evaluate misoprostol (pge1 analogue) effect on acute phase of viral hepatitis b. materials and methods a randomized matched controlled clinical trial w...

Less than 25% of asymptomatic adults have elevated levels of transaminases on a first evaluation, one third of these patients have normal values on a retest. From those who have elevated ALT on retest, some prove to suffer from an acute liver disease (with normal ALT in less than 6 months), and the others represent the category of chronic (more than 6 months) elevation of transaminases. The eti...

In previous cross-sectional studies, we demonstrated that, in most patients with chronic hepatitis C, the composition and complexity of the circulating hepatitis C virus (HCV) population do not coincide with those of the virus replicating in the liver. In the subgroup of patients with similar complexities in both compartments, the ratio of quasispecies complexity in the liver to that in serum (...

BACKGROUND The leaves of Folium Syringae (FS) have been long used as a traditional Chinese folk medicine for their anti-inflammatory effect, utilized as an antibacterial and antiviral treatment. The purpose of this study was to investigate the potential hepatoprotective effects of FS on acetaminophen-induced hepatic injury in primary hepatocytes and mice. METHODS Hepatocytes obtained by the i...

Transaminases are useful biocatalysts for the production of amino acids and chiral amines as intermediates for a broad range of drugs and fine chemicals. Here, we describe the discovery and characterisation of new transaminases from microorganisms which were enriched in selective media containing (R)-amines as sole nitrogen source. While most of the candidate proteins were clearly assigned to k...

Amine transaminases are enzymes that catalyze the mild and selective formation of primary amines, which are useful building blocks for biologically active compounds and natural products. In order to make the production of these kinds of compounds more efficient from both a practical and an environmental point of view, amine transaminases were incorporated into multi-step one-pot reactions. With...

The transamination of aromatic l-amino acids (5-hydroxytryptophan, tryptophan, tyrosine, phenylalanine and kynurenine) was shown to be catalysed by enzyme preparations from rat small intestine. On the basis of the partial purification and characterization of these aromatic amino acid transaminases, it is suggested that rat small intestine contains several kinds of aromatic amino acid transamina...
