Biopharmaceutical characterization of carbamazepine immediate release tablets - In vitro-in vivo comparison
(ECV-Editio Cantor Verlag Medizin Naturwissenschaften, Aulendorf, 2007)
A growing concern for the biopharmaceutical characterization of pharmaceutical products increased the interest in the evaluation and identification of physicochemical properties of drugs and dosage forms that govern its ...
Catecholamines as immunomodulators: A role for adrenoceptor-mediated mechanisms in fine tuning of T-cell development
(Elsevier Science BV, Amsterdam, 2008)
In its simplest form, effective T cell-mediated immunity emanates from the expansion of specific T cells activated tit response to antigen. In establishing and maintaining the peripheral T-cell pool, the thymus plays a ...
Activity of polymer supported cobalt catalyst in the Bray-Liebhafsky oscillator
(Maik Nauka/Interperiodica/Springer, New York, 2009)
The infuence of poly-4-vinylpyridine-co-divinylbenzene-Co2+ catalyst on the Bray-Liebhafsky (BL) oscillator used as the matrix for establishing catalyst's activity was analyzed. The addition of the catalyst do not change ...
Mathematical modeling of pH-surfactant-mediated solubilization of nimesulide
(Taylor & Francis Inc, Philadelphia, 2009)
Aim: The equilibrium-based mathematical model was used to describe the pH-surfactant-mediated solubilization of weakly acidic electrolyte, nimesulide, in buffer solutions. This model assumed that the total drug solubility ...
Investigation of kernel oils of Quercus robur and Quercus cerris
(Springer, New York, 2004)
The kemel oils of Quercus robur and Quercus cerris were obtained by Soxhlet extraction using petroleum ether. Oil yields were found to be 5.2-5.6% and 4.3-4.8% for Q. robur and Q. cerris kemel, respectively (expressed in ...
Composition of Carlina acanthifolia root essential oil
(Springer, New York, 2005)
The root of Carlina acanthifolia All. (Asteraceae) contained 1.0% of essential oil (expressed in g per 100 g of dried plant material). Using GC and GC/MS, nine components were identified (100% of total oil). The structure ...
The Effect of Dietary Selenium Source and Level on Hen Production and Egg Selenium Concentration
(Humana Press Inc, Totowa, 2009)
A 16-week experiment was conducted to compare effects of various levels of sodium selenite (SS) and Se-enriched yeast (SY), on the whole-egg Se content and hen's productivity. One hundred Shaver 579 hens, 27 weeks old, ...
The role of nitric oxide in paraquat-induced oxidative stress in rat striatum
(Inst Agricultural Medicine, Lublin, 2007)
The role of nitric oxide (NO) in paraquat (PQ)-induced neurotoxicity is still not fully understood. In this study we used N-G-nitro-L-arginine methyl ester (L-NAME), a non-selective nitric oxide synthase (NOS) inhibitor, ...
Chemical composition and antimicrobial and antioxidant activity of Seseli rigidum flower essential oil
(Springer, New York, 2009)
Determination of quercetin in pharmaceutical formulations via its reaction with potassium-titanyloxalate: Determination of the stability constants of the quercetin-titanyloxalato complex / Određivanje kvercetina u farmaceutskim preparatima preko reakcije sa kalijum-titaniloksalatom - određivanje konstanti stabilnosti kvercetin-titaniloksalatnog kompleksa
(Srpsko hemijsko društvo, Beograd, 2005)
Asimple, rapid and accurate procedure for the quantitative determination of quercetin in its pure form and in formulations has been developed. The method is based on the spectrophotometric determination of a complex formed ...
