Three enzymatic routes toward ?-hydroxy-?-amino acids by tandem aldol addition–transamination one-pot two-step reactions are reported. The approaches feature an enantioselective addition of pyruvate to various nonaromatic aldehydes catalyzed trans-o-hydroxybenzylidene hydratase-aldolase (HBPA) from Pseudomonas putida. This affords chiral 4-hydroxy-2-oxo acids, which were subsequently enantiosel...

Scarlet fever is a streptococcal infection with a good prognosis. Complications are well described. Hepatitis is a rare complication. We describe a 6-year old boy with scarlet fever, jaundice and elevated liver transaminases.

Enantiopure chiral amines synthesis using omega-transaminases is hindered by an unfavourable equilibrium, but when using isopropylamine as the amine donor the equilibrium can be completely displaced by using a specific dehydrogenase in situ for removal of formed acetone.

The Gram-negative proteobacterium Pseudomonas oleovorans DSM 1045 is considered a promising source for enzymes of biotechnological interest, e.g., hydrolases and transaminases. Here, we present a draft sequence of its 4.86-Mb genome, enabling the identification of novel biocatalysts.

ATAs engineered for having an enlarged small binding pocket were applied the synthesis of enantiomerically pure (R)-benzo[1,3]dioxol-5-yl-butylamine, a chiral component human leukocyte elastase inhibitor DMP 777 (L-694,458). Kinetic resolution racemic amine was performed by using L59A variant (S)-selective ATA from Chromobacterium violaceum (Cv-ATA), providing residual (R)-enantiomer in excelle...

The coexistence of Wilson disease with Alport syndrome has not previously been reported. The diagnosis of Wilson disease and its ongoing monitoring is challenging when associated with an underlying renal disease such as Alport syndrome. Proteinuria can lead to low ceruloplasmin since it is among serum proteins inappropriately filtered by the damaged glomerulus, and can also lead to increased ur...

There are no randomized clinical trials on efficacy of Entecavir in Fulminant Hepatic Failure (FHF) due to Hepatitis B Virus (HBV). Definitive treatment of FHF remains Liver Transplant. However, availability of cadaveric donor organs is limited, and many of the patients with FHF may not be candidates for Liver Transplantation. There are only few case reports on beneficial effects of Entecavir i...

Liver injury secondary to blunt abdominal trauma is a well-defined entity in emergency medicine. A challenge exists in the diagnosis of liver trauma in the stable, wellappearing patient with a history of blunt abdominal trauma. In centres lacking advanced diagnostic modalities an elevation in hepatic transaminases may provide guidance for the rural emergency physician in seeking further imaging...
