BACKGROUND Calcium infusion is used as a pre-treatment before calcium channel blockers to prevent hypotension. Occasional cardioversion with calcium gluconate infusion is seen in patients with paroxysmal supraventricular tachycardia. Several mechanisms have been suggested for mechanism. Herein we report a case presenting with atrial fibrillation but cardioverted with calcium gluconate infusion,...

A practical method for the production of calcium 2-keto-l-gulonate (an intermediate in the Reichstein synthesis of l-ascorbic acid) from d-glucose has been established by using a two-stage fermentation system. d-Glucose was first converted to calcium 2,5-diketo-d-gluconate by a mutant strain of Erwinia sp. in a medium containing d-glucose, corn steep liquor, (NH(4))(2)HPO(4), and CaCO(3). After...

Goddard, J. L. (University of Oklahoma School of Medicine, Oklahoma City), and J. R. Sokatch. 2-Ketogluconate fermentation by Streptococcus faecalis. J. Bacteriol. 87:844-851. 1964.-Streptococcus faecalis 10Cl did not grow with 2-ketogluconate alone as an energy source, but did grow when gluconate was added. More growth was obtained than could be accounted for by the gluconate alone. The requir...

The gntP gene, located between the fim and uxu loci in Escherichia coli K-12, has been cloned and characterized. Nucleotide sequencing of a region encompassing the gntP gene revealed an open reading frame of 447 codons with significant homology to the Bacillus subtilis gluconate permease. Northern (RNA) blotting indicated that the gntP gene was monocistronic and was transcribed as an mRNA with ...

Literature data on the bioavailability of various Mg forms provide scarce information on the best Mg salt to be used in animal and human supplementation. This study aimed to investigate the bioavailability of different forms of Mg in rats using Mg stable isotopes. Eighty male Wistar rats aged 6 weeks were fed a semi-purified Mg-depleted diet for three weeks. The rats were then randomised into t...

OBJECTIVE The main objective of this study was to investigate the effect of brief exposure to subtherapeutic concentrations of chlorhexidine gluconate on germ tube formation of Candida albicans isolates obtained from smokers, diabetics, asthmatics using steroid inhalers and healthy individuals. MATERIALS AND METHODS Forty isolates of C. albicans were used in this study. All these isolates wer...

In this study we developed a new method for accurately determining the pentose phosphate pathway (PPP) split ratio, an important metabolic parameter in the primary metabolism of a cell. This method is based on simultaneous feeding of unlabeled glucose and trace amounts of [U-C]gluconate, followed by measurement of the mass isotopomers of the intracellular metabolites surrounding the 6-phosphogl...

introduction: a desirable characteristic of root canal irrigants is the ability of dissolving soft tissues. sodium hypochlorite, an antibacterial and tissue solvent irrigant used in endodontic treatment is known to be toxic for periapical tissues. chlorhexidine gluconate, an effective antimicrobial agent, is another irrigant with limited tissue dissolving ability. a mixture of a tetracycline is...

The loss of cystic fibrosis transmembrane conductance regulator (CFTR)-mediated transepithelial HCO(3)(-) secretion contributes to the pathogenesis of pancreatic and biliary disease in cystic fibrosis (CF) patients. Recent studies have investigated P2Y(2) nucleotide receptor agonists, e.g., UTP, as a means to bypass the CFTR defect by stimulating Ca(2+)-activated Cl(-) secretion. However, the v...
