Urinary excretion of 4-pyridoxic acid by women using steroid contraceptives and by mental retardates with and without Down's syndrome

The urinary excretion of 4-pyridoxic acid (PIC), the principle end-product of vitamin B₆ metabolism found in human urine, was measured in two populations in whom altered vitamin B₆ metabolism has been reported: in women who use oral contraceptives and ...

Mechanism of two flavoenzymes involved in the degradation of vitamin B6 in bacteria: MHPC oxygenase and 5-pyridoxic acid oxygenase.

, 1990
2-Methyl-3-hydroxypyridine-5-carboxylic acid (MHPC) oxygenase and 5-pyridoxic acid oxygenase are flavoenzymes involved in the degradation of Vitamin B$\sb6$ in bacteria. Both oxygenases have been shown to catalyze the incorporation of two atoms of oxygen

Effects of different energy levels in low-protein diet on liver lipid metabolism in the late-phase laying hens through the gut-liver axis

Journal of Animal Science and Biotechnology
Background The energy/protein imbalance in a low-protein diet induces lipid metabolism disorders in late-phase laying hens. Reducing energy levels in the low-protein diet to adjust the energy-to-protein ratio may improve fat deposition, but this also ...

Evaluation of Adefovir PBPK Model to Assess Biomarker‐Informed OAT1 Drug–Drug Interaction and Effect of Chronic Kidney Disease

CPT: Pharmacometrics & Systems Pharmacology
Evaluation of transporter‐mediated drug–drug interactions (DDI) with endogenous biomarkers, coupled with physiologically‐based pharmacokinetic modeling (PBPK) is envisioned to replace or reduce dedicated DDI clinical trials with clinical probe substrates.
