The effect of magnesium sulphate in releasing calcium emission from interference by phosphate and sulphate has been investigated. Samples were diluted in 10 mM MgSO(4), 2 mM NaCl, giving final calcium concentrations of about 0.05 to 0.10 mM. In this diluent, galvanometer readings were proportional to calcium concentrations up to 0.4 mM. The magnesium sulphate released calcium emission from depr...

Kinetic data for the hydrolysis of potassium pacetylphenyl sulphate by fresh rat liver suspensions suggested that the arylsulphatase activity so observed could be attributed to a single enzyme (Dodgson, Spencer & Thomas, 1953) which was later found to be localized mainly in the microsomes of the liver cell (Dodgson, Spencer & Thomas, 1954a). Preliminary attempts to purify the microsome enzyme (...

A Plackett-Burman factorial design with 15 experiments was conducted to evaluate the influence of seven factors on lipases production by Fusarium solani. The investigated were peptone, tryptone, yeast extract, calcium chloride, potassium phosphate, magnesium sulfate, and copper sulphate. Five fixed variables (cotton oil, pH, temperature, agitation, time) maintained as a response enzymatic activ...

Bacteriocin produced by Lactobacillus brevis OG1 has large spectrum of inhibition against pathogenic, food spoilage microorganisms and various Lactic acid bacteria employed as test strains. The bacteriocin inhibited E coli NCTC 10418 and Enterococcus faecalis, but did not inhibit Candida albicans ATCC 10231 and Klebsiella sp. UCH 15. The antibacterial activity appeared to be pronounced between ...

Several cases of aerosol plumes resulting from trans-Pacific transport were observed between 2 km and 5.3 km at Whistler, BC from 22 April 2006 to 15 May 2006. The fine particle (<1μm) chemical composition of most of the plumes was dominated by sulphate that ranged from 1–5μg m−3 as measured with a Quadrapole Aerosol Mass Spectrometer (Q-AMS). Coarse particles (>1μm) were enhanced in all sulpha...

There is a wide range of remedies available for the treatment of the paroxysmal arrhythmias, which comprise auricular and ventricular paroxysmal tachycardia and paroxysmal flutter and fibrillation. Although vagal stimulation by pressure on the carotid sinus or eyeballs sometimes stops paroxysmal tachycardia, it is not effective in auricular fibrillation. Again, trials have been made of many dru...

This study aimed to convert chrome shaving waste (CSW) generated from leather processing into valuable materials, such as de-chromed activated carbon and basic chromium sulphate. CSW was using three levels of leaching solution potassium carbonate, hydrogen peroxide, water (0.25:0.1:5, 0.5:0.2:5, 0.75:0.3:5, respectively), the resulting chromate converted sulphate sugar reduction method. De-chro...

Whole gut perfusion in humans was used to compare the effect on intestinal water and electrolyte transport of the World Health Organisation oral rehydration solution (solution II, composition in mmol/l: glucose 111, sodium 90, bicarbonate 30, potassium 20; 308 mOsm/kg); a hypertonic commercial oral rehydration solution (solution III, glucose 188, sodium 50, bicarbonate 20, potassium 20 mmol/l; ...

1. Statistical analyses were carried out on results obtained under strictly-controlled conditions in metabolism stalls with forty-one different rations fed to 127 adult non-pregnant dry cows, and with fourteen other different rations fed to thirty-five adult non-pregnant lactating cows that had calved 2-6 months earlier and whose daily milk production ranged from 11 to 20 kg. 2. Correlations be...
