AIM This study evaluated the antibacterial activity and dimensional stability of irreversible hydrocolloids mixed with different concentrations of chlorhexidine gluconate instead of water. MATERIALS AND METHODS Experimental specimens (45 specimens) were prepared and allocated into three groups of 15 each. Group I: Impression material mixed with distilled water served as control. Groups II and...

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-13C]gluconate, followed by measurement of the mass isotopomers of the intracellular metabolites surrounding the 6-phospho...

Abstract Electrodeposition of nickel from slightly acidic gluconate solutions containing chloride or/and sulfate ions was investigated. Electrochemical measurements correlated with bath speciations showed complex and complexes as crucial species affecting cathodic reactions in a potential range up to ?1.3V. At more negative potentials, deposition governed by release cation nickel-gluconate comp...

background chlorhexidine gluconate (chx) is the most common antimicrobial agent used against oral pathogens, however information on its ability to inhibit and disrupt anaerobic single and multispecies biofilms is relatively unknown. objectives the purpose of this study was to test the efficacy of chx for its biofilm inhibition and disruption properties using crystal violet assay. materials and ...

BACKGROUND AND OBJECTIVES Among patients with chronic kidney disease (CKD), differences in proteinuria are seen between intravenous iron preparations after a single dose exposure. This study examined differences in proteinuria between two intravenous iron preparations after multiple doses. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Patients with iron-deficiency anemia and CKD, stratified b...

Glucose may be converted to 6-phosphogluconate by alternate pathways in Pseudomonas aeruginosa. Glucose is phosphorylated to glucose-6-phosphate, which is oxidized to 6-phosphogluconate during anaerobic growth when nitrate is used as respiratory electron acceptor. Mutant cells lacking glucose-6-phosphate dehydrogenase are unable to catabolize glucose under these conditions. The mutant cells uti...

The GntR protein is a negative regulator involved in gluconate-inducible expression of the Bacillus subtilis gnt operon which is responsible for gluconate metabolism. The GntR protein has been purified to homogeneity from an overproducing Escherichia coli strain harboring a gntR gene-carrying plasmid. The total amino acid composition and the NH2-terminal amino acid sequence of the purified prot...

BACKGROUND Clostridium acetobutylicum fermentations are promising for production of commodity chemicals from heterogeneous biomass due to the wide range of substrates the organism can metabolize. Much work has been done to elucidate the pathways for utilization of aldoses, but little is known about metabolism of more oxidized substrates. Two oxidized hexose derivatives, gluconate and galacturon...

Latar Belakang: Chlorhexidine gluconate merupakan antiseptik yang sering digunakan untuk mencegah penyebaran infeksi karena luasnya cakupan tersebut dalam membunuh bakteri. Antiseptik ini juga beberapa bakteri MDRO, salah satunya MRSA. Akan tetapi, seringnya penggunaan dikhawatirkan dapat meningkatkan resistensi MRSA terhadap chlorhexidine gluconate. Objektif: Studi bertujuan mengetahui efektiv...

The Sinorhizobium meliloti megaplasmid pSymA has previously been implicated in gluconate utilization. We report a locus on pSymA encoding a putative tripartite ATP-independent periplasmic (TRAP) transporter that is required for gluconate utilization. The expression of this locus is negatively regulated by a GntR family regulator encoded adjacent to the transporter operon.
