The aromatic amino acids L-phenylalanine and L-tyrosine and their plant-derived natural products are essential in human and plant metabolism and physiology. Here we identified Petunia hybrida and Arabidopsis thaliana genes encoding prephenate aminotransferases (PPA-ATs), thus completing the identification of the genes involved in phenylalanine and tyrosine biosyntheses. Biochemical and genetic ...

Aminotransferases (GOT and GPT) activities in the hemolymph of Bradybaena similaris under experimental condition of starvation were studied. At the 10th day of starvation, GOT activity was 416.6% higher than that observed in the fed snails, being reduced and ranging values near to that shown by the control group onwards. GPT activity only varied significantly at the day-30 of starvation. The re...

A 6 year old boy presenting with a five month history of fever, lethargy, and anorexia, was found to have hepatitis B associated membranous glomerulonephropathy and nephrotic syndrome. After two months treatment with oral lamivudine, his proteinuria cleared and serum albumin and aminotransferases normalised, associated with disappearance of hepatitis B e antigen (HBeAg) and appearance of anti-H...

Interaction of cytosolic apo-aspartate aminotransferase with AMP has been studied under equilibrium conditions; e.g., equilibrium dialysis and spectrophotometric titration. Results show that a 1:1 stoichiometric complex AMP-apo-aspartate aminotransferase monomer is formed. The calculated dissociation constants with the two different experimental techniques are 40.4 x 10(-6) M-1 and 31.4 x 10(-6...

Submit Manuscript | http://medcraveonline.com oral maintenance therapy. A wide range of side effects has been reported, which tempted editors to describe the drug as Pandora’s box, Offerhaus [1]. Hepatotoxicity is a relatively uncommon side effect of amiodarone, and, although asymptomatic elevation of aminotransferases is reported in up to a fourth of all patients, symptomatic hepatic dysfuncti...

BACKGROUND Hepatitis E virus (HEV) infection is a self-limiting viral infection that can lead to severe complications and death. In different regions the epidemiology of this infection varies. In this study we evaluated the seroepidemiology of hepatitis E infection in Jahrom, a city in southern Iran. METHODS This was a cross-sectional descriptive study of serum samples from 477 subjects, incl...
