Rapid Communications in Mass Spectrometry, 2009
Abstract Citrate complexes of Mn and Fe, and potentially those of Cu and Zn, are considered as important low molecular mass species in human serum and cerebrospinal fluid (CSF). For example, Mn is supposed to enter the brain under excess exposure as Mn‐citrate leading to neurotoxic effects.

Comparative studies of radiotracer citrates in oncological models—2. 153Smcitrate and 67Gacitrate
International Journal of Radiation Applications and Instrumentation. Part B. Nuclear Medicine and Biology, 1989153Sm-citrate solutions were prepared from enriched 152Sm2O3 which had been irradiated at 10(12)n cm-2 s-1 in the University of Alberta Slowpoke reactor. 153Sm was rapidly bound (93% in 2 h) by Melanoma 2AB cells in tissue culture upon incubation in the presence of 153Sm-citrate (1.9 nmol 10(6) cells).

Urinary Citrate and Citrate Metabolism
2010Citrate is the most abundant organic anion in human urine. Its urinary excretion rate mainly depends on acid–base status: Alkalosis induces an increase in urinary citrate excretion, whereas acidosis has the opposite effect. It is important to note that citrate utilization by renal cells and urinary citrate excretion are mainly affected by intracellular

Acta Crystallographica Section C Crystal Structure Communications, 1993
The crystal structure of a double salt of potassium dihydrogen citrate and lithium potassium hydrogen citrate monohydrate has been determined. One potassium ion is coordinated with eight O atoms and the other with nine O atoms at M--O distances in the range 2.660 (1) to 3.139 (1) A. Two of these O atoms are shared by both potassium ions.

Intensive and Critical Care Nursing, 1999
Sildenafil is the first of a series of orally active treatments for MED which has resulted in unprecedented demand for treatment and potentially high cost to the NHS. Further oral therapies are likely to follow in the next year or so. In clinical trials, sildenafil produced an erection (sufficient to achieve intercourse) lasting up to 4 h on around 70%

[27] ATP citrate lyase (citrate-cleavage enzyme)
1969Publisher Summary The chapter discusses three different methods by which ATP citrate lyase is assayed by determining the amount of acetyl-CoA or oxaloacetate formed. These methods are: The hydroxamate method: The acetyl-CoA formed is trapped as acetylhydroxamate and the latter is determined by the color produced with FeCl 3 .

Sildenafil citrate (Viagra(R))
Drugs of Today, 2000Sildenafil citrate, a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type V (PDE V), initially designated as compound 92-480-10 by Pfizer, was studied in the late 1980s as an antianginal. An unexpected side effect of the early clinical investigations was improved erectile function among the men studied.
