OBJECTIVE Gabapentin is being investigated as a potential treatment for occasional disturbed sleep. This study assessed the pharmacokinetics and tolerability of gabapentin 500 mg and the commonly prescribed sedative/hypnotic zolpidem tartrate 10 mg, administered separately and in combination. METHODS Forty healthy participants (19 male, 21 female) were randomized into this three-period crosso...

In 2015, plasmid-mediated colistin resistance was reported to be caused by a mobilized phosphoethanolamine transferase gene (mcr-1) in Enterobacteriaceae Here, we announce the complete genome sequence of the earliest d-tartrate-fermenting Salmonella enterica subsp. enterica serovar Paratyphi B isolate harboring mcr-1 from the collection of the German National Reference Laboratory for Salmonella.

The use of antimony compounds, particularly potassium antimonyl tartrate (Tartar emetic), in Cryptococcosis has occasionally been mentioned in the literature,2"' but no experimental study of the therapeutic rationale of the use of antimonials in this infection has to our knowledge ever been under-taken. It did not seem that Tartar emetic was of any therapeutic value, but this should not reflect...

The substrate specificity of fumarase has been studied by measuring the ability of the enzyme to hydrate or dehydrate derivatives of fumarate and L-malate. Fumarase was observed to hydrate fumarate and its derivatives in the order, fluorofumarate > fumarate > chlorofumarate > bromofumarate > acetylenedicarboxylate > iodofumarate > mesaconate. With the exception of fluorofumarate, water was adde...

A simple and sensitive spectrofluorimetric method has been developed for the estimation of brimonidine tartrate in pure and eye drops. Linearity was obeyed in the range of 0.2-3.0 ΅g/ml in dimethyl formamide as solvent at an emission wavelength (λem) of 530 nm after excitation wavelength (λex) of 389 nm with good correlation coefficient of 0.998. The limit of detection and limit of quantificati...

The current work reports an extended theoretical study from our previous experimental work for the enantioselective extraction of amlodipine enantiomers in a biphasic recognition chiral extraction system (BRCES) consisting of hydrophobic D-diisopropyl tartrate dissolved in organic phase (n-decanol) and hydrophilic hydroxypropyl-β-cyclodextrin (HP-β-CD) in aqueous phase (acetate buffer) which pr...

In assay of serum proteins by use of the biuret reaction, dextran can cause turbidity by formation of an insoluble complex of dextran with copper and tartrate (or EDTA) in strongly alkaline solution. Whether or not the turbidity occurs depends on the tartrate concentration: turbidity is maximal at about 10 g/L, absent at 20 g/L or more, and only slight and delayed at 4 g/L. Two biuret reagents,...

In a mew method for the estimation of transferrin by iron-binding capacity iron is added as the tartrate in NaCl with about 10 mM bicarbonate. The excess iron is removed by passage through DEAE-Sephadex A-50 previously treated with the iron chelator disodium catechol-3,5-disulphonate. The iron remaining bound to transferrin is measured without protein precipitation by the use of ferrozine. The ...

AIMS The aim of this study was to examine the effects of bisoprolol (BIS), a selective beta1-adrenoceptor antagonist without partial agonistic activity, on noradrenaline- and phenylephrine-evoked venoconstriction in man using the dorsal hand vein compliance technique. METHODS Twelve healthy male volunteers participated in three weekly experimental sessions. Subjects were allocated to treatmen...
