Normal urine contains an inhibitor of calcium-oxalate crystal growth, and the crystals which first form on a glass fibre when the urine is slowly saturated with calcium and oxalate ions at pH 5路5-6路2 are usually of its monohydrate. The same is found when the urine is from a normal ...
The kinetics of crystal growth of calcium oxalate seed crystals were investigated conductimetrically and potentiometrically at several ionic strengths, in ... FGGMB Amat - 《Journal of Crystal Growth》 被引量: 27发表: 1988年 Stabilization of Calcium Oxalate Precursors during the Pre- and Post-Nu...
Knowledge association of large device libraryAbstract Oblique wave interaction with a two-layer breakwater consisting of perforated front and back wall in the presence of bottom undulations is analyzed. Wave characteristics are studied in the framework of small-amplitude wave theory, and Darcy's law ...

Kidneys release UA into human fluids as the ultimate metabolite of purine nucleotides [1]. Usually, the concentration of UA is dynamically balanced by the body and the normal levels of human UA are 130–460 μM in serum and 1.49–4.46 mM in urine [2]. The presence of UA protects the ...
The present invention pertains to a method for determining an analyte substance or analyte substance mixture of ammonia and/or N-methyl-2-pyrrolidone as a component of a gas in the presence of a dopant mixture by means of an ion mobility spectrometer and to a corresponding ion mobility spectrom...
Human urine is is known to be a heterogeneous medium. However, although growth of urinary crystals in vitro is usually performed in what is assumed to be a homogeneous solution the presence of various agents in the environment in vitro will render solution conditions heterogeneous. The present ...
A method is described for the growth of calcium oxalate dihydrate in normal urine. Soluble chlorophyllin, at a concentration of 20 渭g/ml inhibited the crystallisation and the growth kinetics of the dihydrate crystals. The inhibitory capacity of chlorophyllin was compared with previous results. Data...

We report a new kind of assay system for urine cystine supersaturation that is accurate in the presence of cystine binding thiol drugs. We measured the molar ratio of cystine dissolved per mole of drug. Measured amounts of cystine crystals were incubated in buffer or urine for 48 hours with ...
