Clathrate hydrate is a promising option for gas storage and transportation. Sucrose stearate, an environmentally friendly chemical, was studied in CH4 hydrate formation process to evaluate its effect on gas storage of CH4 hydrate. The experiment was conducted systematically with four different s...

Calorimetry has established that on radical polymerization of methyl methacrylate the isobutyric, methacrylic and polymethacrylic acid esters of 2-fluoro-2,2-dinitroethanol are inhibitors with activity equal within the limits of experimental error. The mean rate constant of inhibition kx = 37·5...

The fatty acids of the triacylglycerol fraction of the latex of the rubber plant consists of 97% of a C18 furanoid fatty acid, 10,13-epoxy-11-methyloctadeca-10,12-dienoic. The free fatty acid fraction is composed of a more equally distributed mixture of 16:0, 18:0, 18:1, 18:2 and the furanoid ac...

Differentiation of organic and conventional dairy products is an important, yet difficult task in food authentication. In this study it was tested whether phytanic acid and pristanic acid can be used as markers for this purpose. Phytanic and pristanic acid cannot be de novo synthesised by mammal...

Anteiso-fatty acids (aFAs) are chiral molecules due to a methyl substituent on the antepenultimate carbon of the otherwise straight acyl chain. 12-Methyltetradecanoic acid (a15:0) and 14-methylhexadecanoic acid (a17:0) are the predominant aFAs in nature but their individual contributions e.g. to...

SummaryThe fatty acids produced by Bacillus subtilis (ATCC-7059) include the optically active fatty acids, d(+)12-methyltetradecanoic acid, and d(+)14-methylhexadecanoic acid. Tracer experiments have shown that the terminal portion of the anteiso fatty acids are synthesized from pyruvate and α-...

BackgroundCyp147G1 is one of 47 cytochrome P450 encoding genes in Mycobacterium marinum M, a pathogenic bacterium with a high degree of sequence similarity to Mycobacterium tuberculosis and Mycobacterium ulcerans. Cyp147G1 is one of only two of these cyp genes which are closely associated with a...

One atomic percent Neodymium ion doped Yttrium oxide, with 25 at% scandium ion (Nd0.02Sc0.5Y1.48O3), was synthesized by nitrate alanine microwave gel combustion followed by calcinations at 1000 °C for 2 h. Phase purity of nanopowder was characterized by X-Ray Diffraction (XRD). Neodymium and sc...

The photochemistry of thin films of manganese(II) 2-ethylhexanoate to produce manganese oxide films is presented. Thin films of manganese(II) 2-ethylhexanoate can be cast onto silicon wafers by spin coating. The FTIR spectroscopy of these films suggests they exist as chains or clusters with the ...

A mechanistic study of the photochemistry of thin films of lead (II) 2-ethylhexanoate is presented. Films of lead (II) 2-ethylhexanote can be cast on silicon solutions by spin coating. Spectroscopic evidence suggests that the molecules are polymeric within the thin film. Irradiation of the film ...

The mechanism of activators regenerated by electron transfer (ARGET) associated with atom transfer radical polymerization (ATRP) has attracted attention because of the transition metal catalyst reduction in the conventional ATRP process. In this paper, a comprehensive mathematical model for solu...

The analysis of trace components in complex biological matrices requires the use of reliable internal standards. For the gas chromatography/mass spectrometry (GC/MS) and high performance liquid chromatography/mass spectrometry (HPLC/MS) analyses, the stable isotope-labelled analogues of the anal...

The teratogenicity of tetrachloroacetone (TCA) was evaluated in CF-1 mice and New Zealand white rabbits. Mice were given 0, 5, 15 or 50 mg/kg/day of TCA by gavage on days 6 through 15 of gestation. Rabbits were given 0, 1, 5, or 10 mg/kg/day on days 6 through 18 of gestation. The incidence of ma...

1,1,3,3-Tetrachloroacetone, an inexpensive, commercially available material, has been shown to be effective in mediating the hydrogen peroxide oxidation of a variety of olefins to epoxides. The chloroacetone is readily recovered for re-use.

A more rapid onset of blepharoptotic activity in mice as well as a significantly increased oral potency relative to reserpine base was noted for reserpine coprecipitates with deoxycholic, cholic, and lithocholic acids. Some enhancement of potency was seen for a reserpine–trihydroxycholane combi...

ObjectiveTo study the pharmacokinetic behavior of tetramethylpyrazine hydrochloride (TMPH) in plasma of rabbits after intranasal administration and the relationship between absorption and dosage, furthermore, to illustrate the effects of borneol and musk used in combination with TMPH on the plas...

Previous studies indicate that reserpine may disrupt dopamine transporter activity. Results presented herein reveal that it also inhibits potently synaptosomal [3H]dopamine uptake. In addition, reserpine administration to rats decreased the Vmax of synaptosomal dopamine transport, as assessed ex...

Background/PurposeActive efflux is known to play a major role in the resistance of many bacteria to antibiotics. To evaluate the possibility of overcoming resistance by suppressing the efflux, we determined the effect of reserpine, an efflux pump inhibitor.

Reserpine is an inhibitor of the vesicular monoamine transporter 2 (VMAT2) and monoamine releaser, so it can be used as a pharmacological model of depression. In the present paper, we investigated the behavioral and neurochemical effects of withdrawal from acute and repeated administration of a ...

Reserpine-induced orofacial dyskinesia is a model that shares some mechanists’ aspects with tardive dyskinesia whose pathophysiology has been related to oxidative stress. The present study was aimed to explore neuroprotective effects of nebivolol, an antihypertensive agent, on reserpine-induced...
