Comprising five microhistories, this book proposes that the French Revolution's religious politics in small towns weakened democratic society to such an extent that it precluded political democracy. It details two revolutionary dynamics that damaged

We developed a new sample preparation method for profiling organic acids in urine by GC or GC–MS. The method includes derivatisation of the organic acids directly in the aqueous urine using trimethyloxonium tetrafluoroborate as a methylating agent,

Derivatization of 2-hydroxycarboxylic acids with methyl and ethyl chloroformate leads to O-alkoxycarbonylalkyl esters. In addition to the main product a number of side-products are formed, which were identified by gas chromatography-mass spectrometry

Elevated plasma concentrations of non-esterified fatty acids (NEFA), due to high fat intake and/or adipose tissue lipolysis, are a hallmark of the metabolic syndrome. We assessed whether certain plasma NEFA species contribute to the chronic low-grade

2-(2-Furoyl)-5-(2-furanyl)-1H-imidazole (FFI) is detected in total histones and the lysine-rich histone 1 fraction isolated from calf thymus after in vitro glycation and hydrolysis with HCl, using gas chromatographic/mass spectrometric analysis. The

Saturated and unsaturated dicarboxylic acids in urine are analyzed within the total profile of organic acids, using the methyl ester derivatives. Twenty-three acids with two carboxyl groups were identified. The method is employed for comparative stud

After O-methyloximation of the carbonyl functions, the organic acids in serum and urine are extracted by anion-exchange chromatography, transformed into the methyl esters and pre-fractionated by thin-layer chromatography. In one of the four fractions
