Dimethylamine was formed from trimethylamine in soils of different pH values. The rate of disappearance of the secondary amine from soil was affected by pH and was markedly reduced under anaerobiosis. The accumulation of dimethylamine in cultures of Micrococcus sp. provided with trimethylamine depended on the nitrogen sources available to the bacterium but was not greatly influenced by the C-N ...
Recent studies suggest that dimethylamine could be a key ternary species in the formation and early growth of atmospheric aerosol particles. We report on nucleation studies for the ternary system of sulfuric acid, water and dimethylamine which have been performed at the CERN CLOUD chamber. These studies were conducted at atmospherically relevant concentrations of sulfuric acid and dimethylamine...
Trans-[PtCl(2)(N,N-dimethylamine)(isopropylamine)] is a novel trans-platinum compound that shows cytotoxic activity in several cisplatin resistant cell lines. The aim of this paper was to analyse, by means of molecular cell biology techniques and total reflection X-ray fluorescence (TXRF), the cytotoxic activity, the induction of apoptosis, the cellular uptake and the DNA binding of trans-[PtCl...
A propanetricarboxylic acid ornamented multi-CeIII encapsulated phospho(III)tungstate [H2N(CH3)2]4Na4H2[Ce4(HP)W4(H2O)14(H2PTCA)2O18][(HPIII)2W22O76]·16H2O (1, H3PTCA = 1,2,3-propanetricarboxylic acid) was obtained by a facile one-step reaction of Na2WO4·2H2O, H3PO3, Ce(NO3)·6H2O, itaconic (H2ICA) and dimethylamine hydrochloride. Notably, the polyanion 1 possesses neotype [(HPIII)2W22O76]12‒ fr...
a mixture of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride is used for the symptomatic treatment of common cold. in this study, a derivative spectrophotometric method based on zero-crossing technique was proposed for simultaneous determination of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride. determination of these drugs was perf...
The distribution of charged species produced by electrospray of an ammonium sulfate solution in both positive and negative polarities is examined using Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS). Positively-charged ammonium bisulfate cluster composition differs significantly from negatively-charged cluster composition. For positively-charged clusters all sulfuric acid...
Sulfuric acid is widely recognized as a very important substance driving atmospheric aerosol nucleation. Based on quantum chemical calculations it has been suggested that the quantitative detection of gas phase sulfuric acid (H2SO4) by use of Chemical Ionization Mass Spectrometry (CIMS) could be biased in the presence of gas phase amines such as dimethylamine (DMA). An experiment (CLOUD7 campai...
Acute intoxication with 2,4-D dimethylamine is rare, often fatal and can cause signs symptoms in different organ systems. This case report describes the effectiveness of alkaline diuresis as a life-saving treatment for chlorophenoxy intoxication, especially healthcare facilities without access to haemodialysis. A patient had attempted suicide by ingesting dimethylamine, toxic effects on central...
