Natural history of alkaptonuria revisited: analyses based on scoring systems.
J. Inherit. Metab. Dis. 34(6) , 1141-51, (2011) Increased circulating homogentisic acid in body fluids occurs in alkaptonuria (AKU) due to lack of enzyme homogentisate dioxygenase leading in turn to conversion of HGA to a pigmented melanin-like polymer, known as ochronosis. The tissue damage in AKU is due ... |

A quantitative assessment of alkaptonuria: testing the reliability of two disease severity scoring systems.
J. Inherit. Metab. Dis. 34(6) , 1153-62, (2011) Alkaptonuria (AKU) is due to excessive homogentisic acid accumulation in body fluids due to lack of enzyme homogentisate dioxygenase leading in turn to varied clinical manifestations mainly by a process of conversion of HGA to a polymeric melanin-like pigment... |

A 3-year randomized therapeutic trial of nitisinone in alkaptonuria.
Mol. Genet. Metab. 103(4) , 307-14, (2011) Alkaptonuria is a rare, autosomal recessive disorder of tyrosine degradation due to deficiency of the third enzyme in the catabolic pathway. As a result, homogentisic acid (HGA) accumulates and is excreted in gram quantities in the urine, which turns dark upo... |

DFT for exploring the antioxidant potential of homogentisic and orsellinic acids.
Pak. J. Pharm. Sci. 26(6) , 1209-14, (2013) In recent years, much attention has been focused on the antioxidant potential of different phenolic acids. But still no theoretical investigation is reported on the antioxidant potential of Homogentisic and Orsellinic acids. In this study, computational inves... |
