BACKGROUND AND PURPOSE Transient receptor potential melastatin 3 (TRPM3) proteins form non-selective but calcium-permeable membrane channels, rapidly activated by extracellular application of the steroid pregnenolone sulphate and the dihydropyridine nifedipine. Our aim was to characterize the steroid binding site by analysing the structural chemical requirements for TRPM3 activation. EXPERIME...

1. Urinary glycosaminoglycans were recovered from the papain digest of polyanions precipitated sequentially by cetylpyridinium chloride and sodium acetate-saturated ethanol. Those from the early morning urine of 48 stone formers and 43 normal control subjects measured 11 and 16 micrograms of uronic acid/ml of urine, respectively. 2. Preparative agarose gel electrophoresis of the recovered glyco...

This paper describes an experimental study on calcium sulphate scaling and prevention by newly treated polyacrylamide in a laboratory model. In order to study the inhibiting capacity of the chemical used, experiments were performed in solutions involving treatment of synthetic sea water with different concentrations of the polymer. Polyacrylamide gave significantly lower precipitation rate comp...

BACKGROUND Magnesium sulphate has been used in some settings as a tocolytic agent to inhibit uterine activity in women in preterm labour with the aim of preventing preterm birth. OBJECTIVES To assess the effects of magnesium sulphate therapy given to women in threatened preterm labour with the aim of preventing preterm birth and its sequelae. SEARCH METHODS We searched the Cochrane Pregnanc...

A two-dimensional finite difference model has been developed to describe the reduction of kilogram quantities dehydrated phosphogypsum. The model's scope limited focus on heat transfer and reactions that occur within a mass material contained in vessel inside furnace rather than also including effects vessel. Changes properties (k, p, Cp) are incorporated as composition changes chemical progres...

The effect of calcium on saprophytic growth and pathogenicity of Phytophthora cinnamomi Rands was studied as well as the influence of calcium on the resistance of avocado to root rot caused by the pathogen. Saprophytic growth of the pathogen was increased significantly by calcium, although the pathogenicity of the fungus was not influenced significantly. Ungrafted Edranol, Duke 7 and Martin Gra...

The sensitivity of H. Pylori to antibiotic treatment is well known. Politherapy (omeprazole or pantoprazole or ranitidine, amoxicillin and/or azithromycin and/or clarithromycin, metronidazole and bismuth citrate) notably changed the percentage of H. pylori eradication but rarely resolutive. Periodontal pockets treatment with topic metronidazole, calcium sulphate and potassium sulphate resulted ...

Of the factors tested, the source and concentration of carbon and nitrogen in the medium exerted maximum effect on growth and acid production. Glucose (15%) and urea (0.14%) induced glucose oxidase synthesis and optimum yield of calcium gluconate. Potassium dihydrogen phosphate (0.2%) and magnesium sulphate (0.06%) stimulated glucose oxidase activity and calcium gluconate production. Borax at a...
