A large section of the North American population is not meeting recommended intakes for magnesium (Mg). Supplementation and consumption of Mg-fortified foods are ways to increase intake. Currently, information on Mg bioavailability from different compounds and their efficacy in improving Mg status is scant. This study compared the relative ability of inorganic and organic Mg compounds to preserve the Mg status of rats when fed at amounts insufficient to retain optimal Mg status. Male Sprague-Dawley rats (n=12/diet group) were fed one of eight test diets supplemented with phytic acid (5 g/kg diet) and low levels of Mg (155 mg elemental Mg/kg diet) from Mg oxide, Mg sulphate, Mg chloride, Mg citrate, Mg gluconate, Mg orotate, Mg malate or ethylenediaminetetraacetic acid disodium Mg salt for five weeks...

We examined 150 pregnant women with essential hypertension (EHT), EHT and connective tissue dysplasia (CTD), and healthy. Presence of CTD aggravated clinical picture of EHT and was associated with pronounced cardialgic, neurological, asthenic, vertebrogenic, visceral, and other syndromes. The use of antihypertensive, metabolic (magnesium orotate) drugs, sedative and uroseptic phytotherapy, application of other nondrug measures in conditions of multidisciplinary dynamic support of the gestational period facilitated regress of clinical symptoms of EHT and EHT+CTD, favorable course of pregnancy and successful delivery...

Orotic acid and its salts chronically administered have been shown to significantly improve cardiac function in pathological settings associated with ischemia-reperfusion (I/R) injury. The aim of our study was to investigate the effect of magnesium orotate (Mg-Or) administration at the onset of post-ischemic reperfusion on myocardial function and infarct size (IS). Ex-vivo experiments performed on isolated perfused rat hearts were used to compare Mg-Or administration with a control group (buffer treated), ischemic post-conditioning, orotic acid treatment, and MgCl2 treatment...

Dimeric Salmonella typhimurium orotate phosphoribosyltransferase (OMP synthase, EC 2.4.2.10), a key enzyme in de novo pyrimidine nucleotide synthesis, has been cocrystallized in a complete substrate E·MgPRPP·orotate complex and the structure determined to 2.2 Å resolution. This structure resembles that of Saccharomyces cerevisiae OMP synthase in showing a dramatic and asymmetric reorganization around the active site-bound ligands but shares the same basic topology previously observed in complexes of OMP synthase from S...

A whole-cell biocatalytic process for uridine 5'-monophosphate (UMP) production from orotic acid by Saccharomyces cerevisiae was developed. To rationally redistribute the metabolic flux between glycolysis and pentose phosphate pathway, statistical methods were employed first to find out the critical factors in the process. NaH(2)PO(4), MgCl(2) and pH were found to be the important factors affecting UMP production significantly. The levels of these three factors required for the maximum production of UMP were determined: NaH(2)PO(4) 22...

In the current era cardiac surgeons are being called upon to operate upon older, sicker patients. The effect is to augment oxidative stress and increase the rate of post-operative complications and ultimately mortality. We have developed antioxidant-based pre-treatment regimes initially based on coenzyme Q(10). A randomised trial of coenzyme Q(10) in elective cardiac surgery patients demonstrated augmented plasma and cardiac mitochondrial membrane coenzyme Q(10) content, improved mitochondrial respiration and increased myocardial tolerance of oxidative stress...

The purpose of the present research was comparative study of anti-inflammatory action of some Mg salts in rats fed with Mg-deficient diet. It was shown in our study that administration of Mg L-aspartate with pyridoxine leads to higher compensation of Mg deficiency in rats with diet-induced Mg depletion as compared with other Mg supplementations. According to the Mg deficiency correction rate Mg salts may be ranged in the following order: Mg L-aspartate with pyridoxine > or = Mg chloride with pyridoxine > or = Mg lactate with pyridoxine > or = Mg L-aspartate > Mg chloride > Mg orotate...

Orotate phosphoribosyltransferase (OPRTase, EC 2.4.2.10) catalyzes the Mg2+-dependent condensation of orotic acid (OA) with PRPP (5-alpha-d-phosphorylribose 1-diphosphate) to yield diphosphate (PPi) and the nucleotide OMP (orotidine 5'-monophosphate). We have determined the structures of three forms of Saccharomyces cerevisiae OPRTase representing different structural and enzymatic intermediates. The structures include the apoenzyme (2.35 A resolution); a ternary complex of enzyme, Mg2+-PRPP, and OA (1.74 A resolution); and the binary product complex of enzyme with OMP (1...

The pyrE gene, encoding orotate phosphoribosyltransferase (OPRTase), was cloned by nested PCR and colony blotting from Corynebacterium ammoniagenes ATCC 6872, which is widely used in nucleotide production. Sequence analysis shows that there is a lack of an important conserved lysine (Lys 73 in Salmonella enterica serovar Typhimurium OPRTase) in the C. ammoniagenes OPRTase. This lysine has been considered to contribute to the initiation of catalysis. The enzyme was overexpressed and purified from a recombinant Escherichia coli strain...

Presently is no consensus of opinion of the size of human optimal daily allowance as for thiamine and riboflavin, so for magnesium, what their content in polyvitamin and mineral preparations testify to. The study was conducted in 60 volunteers, who once took oral dosing of magnesium -bearing preparation "Magnerot" (500 mg of magnesium orotat converting to Mg2+ 32,8 Mg) and "Centrum" (100 mg of magnesium oxide converting to Mg2+ - 60,3 Vg) or vitamins B1 and B2 in 10, 20 and 30 mg doses. The received data testify that during the application of both of these preparations, equal concentration of this element takes place, though in case of magnesium oxide it happens later...

UNLABELLED: Cardiac surgery represents major metabolic, physical and mental stresses associated with an increased production of reactive oxygen species. These stresses may hamper post-operative recovery, increasing hospitalisation times and operative mortality. We conducted a quality assurance and feasibility study to evaluate and monitor the safety and efficacy of a new program of combined pre-operative metabolic (enhanced antioxidant), physical and mental therapy to counter these stresses prior to cardiac surgery...

Magnesium orotate dihydrate (MO) has the sum formula C10H6MgN4O8 x 2H2O and a MG of 370.52. The salt is poorly soluble in water and hence does not bind gastric acid nor does it exhibit noteworthy laxative effects upon oral administration in contrast to easily dissociable Mg salts. As a source of magnesium (Mg), MO is indicated for the oral treatment of extracellular Mg deficiency. Orotic acid (OA), the second active ingredient of MO, is a key intermediate in the biosynthetic pathway of pyrimidines and is shown to improve the energy status of injured myocardium by stimulating, a...
