HPLC METHOD FOR SEPARATING ENANTIOMERS OF IMIDAZOLE DERIVATIVES - ANTIFUNGAL COMPOUNDS.

Acta poloniae pharmaceutica
The aim of this study was to test separation possibility of enantiomers of nine active substances belonging to imidazole derivatives: bifonazole, butoconazole, econazole, enilconazole, fenticonazole, isoconazole, miconazole, sertaconazole and tiocona...

DEVELOPMENT AND VALIDATION OF FAST REVERSED-PHASE HPLC METHOD FOR ANALYSIS OF ESOMEPRAZOLE IN RABBIT PLASMA.

Acta poloniae pharmaceutica
The present study focused to develop rapid, accurate and sensitive reversed-phase high pressure liquid chromatography method for the quantification of esomeprazole (ESO) magnesium in rabbit plasma. Chromatographic separation was achieved isocraticall...

REVERSE PHASE HIGH PERFORMANCE LIQUID CHROMATOGRAPHY METHOD FOR DETERMINATION OF 5-FLUOROURACIL IN RABBIT PLASMA.

Acta poloniae pharmaceutica
A simple, efficient, accurate and selective HPLC method has been developed and validated successfully for the estimation of 5-fluorouracil in rabbit plasma. The drug was eluted by using Supelco C18 column (1.5 cm x 4.6 mm, 5 μm) with a mobile phase c...

Lactate levels and risk of lactic acidosis with metformin in diabetic kidney disease patients.

Saudi journal of kidney diseases and transplantation : an official publication of the Saudi Center for Organ Transplantation, Saudi Arabia
Metformin as an oral antidiabetic drug (OAD) is not recommended in renal failure due to the presumed risk of lactic acidosis though it has advantages in cardiovascular protection with a low risk of hypoglycemia. Few studies have measured lactic acid ...

Electrosynthesis of magnetoresponsive microrobot for targeted drug delivery using calcium alginate.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Targeted drug delivery systems deliver drugs precisely to a specific targeted site inside the body, and can also release the drugs with controlled kinetics to prolong the efficacy of single dose administration. The advantageous properties of hydrogel...

Application of response surface methodology and artificial neural network: modeling and optimization of Cr(VI) adsorption process using Dowex 1X8 anion exchange resin.

Water science and technology : a journal of the International Association on Water Pollution Research
We report the adsorption efficiency of Cr(VI) on a strong anionic resin Dowex 1X8. The Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis of this adsorbent were investigated. Response surface methodology was applied t...

[Condition optimization for bio-oxidation of high-S and high-As gold concentrate].

Wei sheng wu xue bao = Acta microbiologica Sinica
OBJECTIVE: To study the effects of temperature and lixivium return on the concentrate bio-oxidation and rate of gold cyanide leaching.

Improvement of the Performance of an Electrocoagulation Process System Using Fuzzy Control of pH.

Water environment research : a research publication of the Water Environment Federation
The removal efficiencies of electrocoagulation (EC) systems are highly dependent on the initial value of pH. If an EC system has an acidic influent, the pH of the effluent increases during the treatment process; conversely, if such a system has an al...

[Biotransformation and safety of cotton stalk alkaline peroxide mechanical pulping waste liquor].

Wei sheng wu xue bao = Acta microbiologica Sinica
OBJECTIVE: We studied the conditions of culturing Bacillus subtilis SY1 to treat cotton stalk alkaline peroxide mechanical pulping waste water, and evaluated afterwards the safety of its release to plants and animals.
