BACKGROUND Zinc gluconate and zinc acetate lozenges have been reported to shorten the duration of common colds in a dose-response manner when the amount of the active ingredient, positively charged zinc ions, is sufficient. OBJECTIVE To improve results using a zinc gluconate nasal spray with zinc orotate lozenges. DESIGN Double-blind, placebo-controlled clinical trial. SETTING Private phy...

OBJECTIVE To model the cost-effectiveness impact of routine use of an antimicrobial chlorhexidine gluconate-containing securement dressing compared to non-antimicrobial transparent dressings for the protection of central vascular lines in intensive care unit patients. DESIGN This study uses a novel health economic model to estimate the cost-effectiveness of using the chlorhexidine gluconate d...

BACKGROUND Protection of the catheter site by antimicrobial agents is one of the most important factors in the prevention of infection. Povidone iodine and chlorhexidine gluconate are the most common used agents for dressing. The purpose of this study was to compare the effects of povidone iodine, chlorhexidine gluconate and octenidine hydrochloride in preventing catheter related infections. ...

BACKGROUND The clinical use of autologous platelet concentrates (also known as platelet-rich plasma) on the field of regenerative therapy, in the last decade has been the subject of several studies especially in equine medicine and surgery. The objectives of this study was: 1) to describe and compare the cellular population in whole blood, lower fraction (A) and upper fraction (B) of platelet c...

Several metabolites of the pentose phosphate pathway, together with related intermediates of the Embden-Meyerhof pathway, were measured in cerebral tissue of mice after periods of ischemia, anesthesia by phenobarbital, hyperthermia, hypothermia, and iodoacetate and fluoroacetate poisoning. Normal levels (micromoles per kg) were found to be 6-P-gluconate, 10; ribulose-S-P, ‘7; xylulose-5-P, 14; ...

The value of the multivariate data analysis tools principal component analysis (PCA) and principal component discriminant analysis (PCDA) for prioritizing leads generated by microarrays was evaluated. To this end, Pseudomonas putida S12 was grown in independent triplicate fermentations on four different carbon sources, i.e. fructose, glucose, gluconate and succinate. RNA isolated from these sam...

Objectives The main objective is to evaluate the efficiency in removal of smear layer of mixture of tetracycline, acid and detergent (MTAD), sodium hypochlorite (NaOCl), ethylenediaminetetraacetic acid (EDTA) and chlorhexidine gluconate by scanning electron microscope (SEM) evaluation and also to evaluate the antimicrobial action of the same irrigants against standard culture strains of Enteroc...

Gluconate is one of the preferred carbon sources of Escherichia coli, and two sets of gnt genes (encoding the GntI and GntII systems) are involved in its transport and metabolism. GntR represses the GntI genes gntKU and gntT, whereas GntH was previously suggested to be an activator for the GntII genes gntV and idnDO-gntWH. The helix-turn-helix residues of the two regulators GntR and GntH exhibi...

Using a standard plaque assay and clinical isolates of herpes simplex virus (HSV), we have tested the ability of zinc salts to inactivate HSV. Virus was treated by incubation at 37 degrees C with zinc salts in morpholinepropanesulfonic acid-buffered culture medium and was then diluted and plated onto CV-1 cells for detection and quantitation of remaining infectious virus. Of 10 randomly chosen ...
