Long-chain fatty acids are synthesized from citrate in an undialyzed soluble enzyme system from pigeon liver at a rate comparable to that observed when acetate is used as a precursor. The first enzymic step for citrate incorporation is probably its breakdown to acetyl-CoA and oxaloacetate catalyzed by the citrate~cleavage enzyme. Experiments with variously labeled citrate show good incorporatio...

Tri-sodium citrate, the focus of this article, is one such alternative. The article will include consideration of the anticoagulant properties of citrate, some detail of how tri-sodium citrate is used to anticoagulate the dialysis pathway, and the advantages of using citrate rather than standard heparin anticoagulation. The use of tri-sodium citrate is not without risk; the potentially harmful ...

The regulation of the fate of acetyl units derived from the P-oxidation of L( -)-palmitylcarnitine was studied using isolated rat liver mitochondria. Citrate synthesis from acetyl-CoA was dependent upon the concentration of Lmalate, the immediate precursor of oxalacetate in this system. The independence of the rate of citrate formation on the means used to stimulate respiration, e.g. ADP for co...

There are many reasons for considering the possibility that the metabolism of citrate is interrelated with the physiological effects of vitamin D and with the equilibrium of calcium and phosphorus in the body. Hamilton and Dewar10 and Shohl'7 demonstrated that the addition of citrate to rachitogenic diets resulted in prevention or cure of rickets in rats. Subsequently, Shohl and Butler1' showed...

BACKGROUND In 2003, it became legal in the UK for syringe exchange programmes (SEPs) to provide citrate to injecting drug users to solubilise heroin. Little work has been undertaken on the effect of policy change on SEP function. Here, we examine whether the introduction of citrate in Cheshire and Merseyside SEPs has altered the number of heroin/crack injectors accessing SEPs, the frequency at ...

Lead citrate is a key precursor for the green recycling of spent lead acid battery paste in a citric acid/sodium citrate (CA/SC) solution. In this study, the main paste component, PbSO4, was leached and crystallized to yield lead citrate. Results showed that the leaching of PbSO4 in citric acid/sodium citrate solution was remarkably enhanced by an increase in temperature from 35 ◦C to 95 ◦C and...

121 women with polycystic ovarian syndrome and clomiphene citrate resistance underwent laparoscopic ovarian cautery, 63 patients were type i or typical pcos with ovarian volume >8ml and 58 patients were type ii pcos with ovarian volume <8ml. serum concentrations of luteinizing hormone (lh), follicular stimulating hormone (fsh), prolactin (prl), testosterone (t), and dehydroepiandrosterone sulfa...

objective(s):higher cellular reactive oxygen species (ros) levels is important in reducing cellular energy charge (ec) by increasing the levels of key metabolic protein, and nitrosative modifications, and have been shown to damage the cardiac tissue of diabetic mice. however, the relation between energy production and heart function is unclear. materials and methods:streptozotocin (stz, 150 mg/...

introduction: aim was to study the influence of serum testosterone and urinary citrate on the formation of urinary stones in men and women, and to apply the findings for preventing urolithiasis. methods: we studied 200 patients (100 were men and 100 women) who had referred to the urology clinic at imam khomeini hospital and seda sima eswl center. in both groups, 50 were stone formers and 50 wer...

objective: the aim of this study was to assess the accuracy of ovarian reserve tests, mainly basal and clomiphene stimulated follicle stimulating hormone (fsh) concentrations. materials and methods : a prospective cohort study was conductedon 120 infertile patients referring to mirza koochak khan hospital for ivffrom 2004 to 2006. all the patients underwent clomiphene citrate challenge test (cc...
