Physiology and pathophysiology of organic acids in cerebrospinal fluid.
J. Inherit. Metab. Dis. 16(4) , 648-69, (1993) Concentrations of organic acids in cerebrospinal fluid (CSF) appear to be directly dependent upon their rate of production in the brain. There is evidence that the net release of short-chain monocarboxylic acids from the brain is a major route for removing th... |

Age-related reference values for urinary organic acids in a healthy Turkish pediatric population.
Clin. Chem. 40(6) , 862-6, (1994) Organic acid concentrations were quantified by gas chromatography and the individual acids identified by mass spectrometry in urine specimens from a healthy Turkish pediatric population of ages 2 days to 16 years, subdivided into five age groups. We quantifie... |

Metabolomic profiles delineate potential role for sarcosine in prostate cancer progression.
Nature 457(7231) , 910-4, (2009) Multiple, complex molecular events characterize cancer development and progression. Deciphering the molecular networks that distinguish organ-confined disease from metastatic disease may lead to the identification of critical biomarkers for cancer invasion an... |

Coformer screening using thermal analysis based on binary phase diagrams.
Pharm. Res. 31(8) , 1946-57, (2014) The advent of cocrystals has demonstrated a growing need for efficient and comprehensive coformer screening in search of better development forms, including salt forms. Here, we investigated a coformer screening system for salts and cocrystals based on binary... |

Urinary and plasma organic acids and amino acids in chronic fatigue syndrome.
Clin. Chim. Acta 361(1-2) , 150-8, (2005) Previous work by others have suggested the occurrence of one or more chemical or metabolic 'markers' for ME/CFS including specific amino acids and organic acids and a number of unidentified compounds (CFSUM1, CFSUM2). We have shown elsewhere that CFSUM1 is pa... |

Detection of autosomal dominant polycystic kidney disease by NMR spectroscopic fingerprinting of urine.
Kidney Int. 79(11) , 1244-53, (2011) Autosomal dominant polycystic kidney disease (ADPKD) is a frequent cause of kidney failure; however, urinary biomarkers for the disease are lacking. In a step towards identifying such markers, we used multidimensional-multinuclear nuclear magnetic resonance (... |

Application of gas chromatography/flame ionization detector-based metabolite fingerprinting for authentication of Asian palm civet coffee (Kopi Luwak).
J. Biosci. Bioeng. 120 , 555-61, (2015) Development of authenticity screening for Asian palm civet coffee, the world-renowned priciest coffee, was previously reported using metabolite profiling through gas chromatography/mass spectrometry (GC/MS). However, a major drawback of this approach is the h... |

A novel amino acid analysis method using derivatization of multiple functional groups followed by liquid chromatography/tandem mass spectrometry.
Analyst 140(6) , 1965-73, (2015) We have developed a novel amino acid analysis method using derivatization of multiple functional groups (amino, carboxyl, and phenolic hydroxyl groups). The amino, carboxyl, and phenolic hydroxyl groups of the amino acids were derivatized with 1-bromobutane s... |

Impact of three commercial feed formulations on farmed gilthead sea bream (Sparus aurata, L.) metabolism as inferred from liver and blood serum proteomics.
Proteome Sci. 12(1) , 44, (2014) The zootechnical performance of three different commercial feeds and their impact on liver and serum proteins of gilthead sea bream (Sparus aurata, L.) were assessed in a 12 week feeding trial. The three feeds, named A, B, and C, were subjected to lipid and p... |
