among the different reducing agents tributyltin hydride was found to be a powerful reducing agent for the denitration of a series of tertiary and secondary nitroesters. the organotin residues removed from the crude product using saturated potassium fluoride solution. the yield of the reactions was 62-98%.

The phosphoglycerate transport system was employed to supply energy-depleted, lysozyme-treated Salmonella typhimurium cells with a continuous intracellular source of phosphoenolpyruvate. When the cells had been induced to high levels of the phosphoglycerate transport system, a low extracellular concentration of phosphoenolpyruvate (0.1 mM) half maximally stimulated uptake of methyl alpha-glucos...

This work explores the effect of additives on the pouring temperature in a waterworks and industrial calcium fluoride sludge co-melting system. Two kinds of sludge were mixed in various ratios to find a mixing ratio at which the operating temperature for subsequent additive tests was relatively low. Various proportions of either sodium carbonate (Na2CO3) or potassium carbonate (K2CO3) reagent w...

This study was done to assess the influence of the topical application of two different desensitizing agents on dentin permeability and dentinal tubule occlusion. Twenty-one rats provided 84 teeth: 36 for the in vitro and 48 for the in vivo investigation. The following agents were tested: Group 1, 2% potassium nitrate plus 2% sodium fluoride gel; Group 2, 5% sodium fluoride varnish; Group 3, 3%...

We recently started estimating glycosylated hemoglobin (HbA1) by using an agarose electrophoresis system (Corning Medical and Scientific, Palo Alto, CA 94306). It is recommended in the manufacturer’s literature that potassium EDTA-anticoagulated samples should be used. We routinely estimate glucose in fluoride/oxalate anticoagulated samples, so we decided to compare results for HbA1 samples ant...
