Nine healthy volunteers were studied on the seventh day of dosing at 21:00 h with nizatidine 150 mg (N 150), nizatidine 300 mg (N 300), ranitidine 300 mg (R 300), or placebo, given in a predetermined random order. The double-blind 24 hour studies, using the Royal Free Hospital standard protocol, simultaneously measured intragastric acidity and plasma gastrin concentration. Compared with placebo...

x-ray photoelectron and electron energy loss spectroscopic (xps-eels) studies reveal that the following species are present when a mixture of co2 and water vapour is exposed to the clean mg(100) surface at 110k: co3(a), c(a) ch(a), oh(a). the reactive chemisorptions of co2 and h2o vapour coadsorbed on a mg surface leads to the formation of ch bond. increasing the temperature to 400 k shows the ...

an experiment was conducted to study the micropropagation of satureja khuzistanica. the seeds were planted in 1/2ms medium. after germination and growth of plantlets, they were subcultured in fresh medium. then, they cultured into medium supplemented by different concentrations of ba and kinetin. results showed that, the highest proliferation (2.4 shoots) was observed at concentrations of 0.5 m...

in this work firstly fe3o4 nanoparticles were synthesized via a sono-chemical method. at the second step magnesium hydroxide shell was synthesized on the magnetite-core under ultrasonic waves. for preparation fe3o4-mgo the product was calcinated at 400 ºc for 2h. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform ...
