introduction methylene blue was first described for the treatment of methemoglobinemia but practical usage of the compound for surgical purpose is common. the aim of this report is to describe a case of hemolysis in neonatal period as a potential hazard of methylene blue toxicity without presence of g6pd deficiency. case presentation in october 2015, a 36-week ga female infant with 2.05 kg weig...

In this paper, dye removal ability of the surface modified nanoparticle SMN copper ferrite from single and quaternary systems was investigated. Acid Blue 92 AB92, Direct Green 6 DG6, Direct Red 23 DR23 and Direct Red 80 DR80 were used as model compounds. The effect of surfactant concentration, adsorbent dosage, dye concentration and pH on dye removal was evaluated. The adsorption isotherm and k...

Experimental studies of the ring-closing metathesis reaction of 1,8-nonadiene and the ROMP reaction of cycloheptene show that the rate of isomerisation is not correlated to the initiation rate of the pre-catalyst, and that the absence of phosphine leads to a greatly increased rate of isomerisation. A range of pre-catalysts and solvents were probed and it is proposed that the isomerisation is me...

Ruthenium trihydrides containing N-heterocyclic carbene ligands display large quantum mechanical exchange couplings in their 1H NMR spectra: DFT calculations are used to explore this phenomenon and to compare them to their phosphine congeners.

Reactions of [(η(6)-cymene)Ru(μ-Cl)Cl]2 with acylpyrazolone ligands HQ' (HQ' in general; in detail, HQ(CH2Cl) = 2-chloro-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone), HQ(hex) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)heptan-1-one), HQ(nPe) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3,3-dimethylbutan-1-one)), in the presence of base, gave the corresponding [(η(6)-cymene...

Repair of a massive meniscal defect remains a challenge in the clinic. However, targeted magnetic cell delivery, an emerging technique, may be useful in its treatment. The present study aimed to determine the effect of targeted intra-articular injection of superparamagnetic iron oxide (SPIO)-labeled adipose-derived mesenchymal stem cells (ASCs) in a rabbit model of a massive meniscal defect. AS...

Mix consortia of Bacillus sp was used to decolorize Direct Blue dye 2B. The bacterial cultures exhibited 60 % decolorization ability within 48 h at temperature 40 o C and pH 7. Maximum rate of decolorization was observed (60%) when starch was supplemented in the medium. Decolorization of Direct Blue dye 2B was monitored by TLC, which indicated that dye decolorization was due to its degradation ...

1. The effect of MgCl(2) concentration on the interaction of Alcian Blue 8GX and glycosaminoglycans in the urine of patients with mucopolysaccharidosis was studied by using a new quantitative micro method for the measurement of Alcian Blue-glycosaminoglycan complexes. This provided a means of measuring the critical electrolyte concentrations of urinary glycosaminoglycans. 2. Theoretical conside...
