(2006)This work shows the synthesis and characterization of new carbonyl complexes derived of 1,8-naphthyridine. Covalently bonded complex can be successfully employed in building of supramolecular structures. Copyright © 2005 ...
-
(1997)Food-induced changes on bioavailability of 2 sustained release theophylline matrix tablets, which uses an hydrophilic matrix of Carbopol 974P and lipid matrix of hydrogenated castor oil (Cutina HR) as sustaining agents, ...
-
(1996)Tire antipyretic and antiinflammatory properties of a new sesquiterpene, spartidienedione, isolated from Psila spartioides (Asteraceae) were evaluated in rabbits and guinea pigs. At the dose of 25 mg/kg, this substance ...
-
(2004)This article describes the basis and development of the solid dosage form section of an educational CD-ROM, including both the theoretical and self-evaluation sections.
-
(1993)The absolute biovailability of a sustained release tablet developed in our laboratory was evaluated. The formulation employs acrylic resins Eudragit as the sustaining release system and tablets were obtained using conventional ...
-
(Kluwer Academic Publishers, 1992)Azotobacter vinelandii was better than either Derxia gummosa or Rhizobium trifolii for sorption of UO2 2+. Its maximum binding capacity was 0.25 mmol UO2 2+/g dry biomass with an affinity constant of 333 l/mmol at pH 4.1 ...
-
(1992)Metal removal by seven strains of Bacillus and Micrococcus was investigated. The culture age of the cells had little or no effect on their sorption capacity. Using the Langmuir isotherm, it was possible to determine that ...
-
(1992)Lifetimes of pyrene incorporated into large unilamellar vesicles of dipalmitoylphosphatidylcholine and dioctadecyldimethylammonium chloride increase when the temperature increases prior to the melting temperature of the ...
-
(1992)Nimodipine, a calcium antagonist belonging to the dihydropyridine family, produces a well‐defined polarographic peak due to the four‐electron reduction of the nitro group. This peak was used to track the photodecomposition ...
-
(1989)A 300 mg controlled-release theophylline formulation was developed as a tablet prepared by wet granulation using the acrylic resins Eudragit S 100(R) and Eudragit RSPM(R). The tablet was compared with a marketed ...
-
(Real Academia de Farmacia, 1988)
-
(Informa Healthcare, 1988)A study was done of the effect of blending time on similar mixtures containing nitrofurantoin both in crystalline and macrocrystalline forms. The powder mixture operations were performed using a Twin-Shell Blender (V-type). ...
-
(1988)The polymerization of methyl methacrylate photosensitized by benzion methyl ether over a wide range of initiator absorbances was investigated. Both the polymerization rate and the polymer molecular weight distribution are ...
-
(1989)2,2′-Azobis-[2-amidinopropane] initiated lipid peroxidation of egg yolk phosphatydil choline liposomes was measured by oxygen uptake and the emitted visible luminescence. Lipid peroxidation involved a chain process (kinetic ...
-
(Elsevier Ltd, 1996)The preparation and spectroscopic properties of mononuclear cationic complexes of rhodium(I) coordinated to the diolefin 2,5-norbornadiene (NBD) and to the heterocyclic nitrogen ligands 6,7-dihydrodipyrido-[2,3-b:3′,2′-j ...
-
(2010)Dimethoate, diazinon, parathion methyl, pirimiphos methyl, malathion, fenthion, chlorpyriphos, methidathion and azinphos methyl were determined in 71 olive oil samples produced in Chile from different varieties of olives ...
-
(Nature Publishing Group, 2018)Cigarette smoke is associated with several pathologies including chronic respiratory diseases and cancer. In addition, exposure to cigarette smoke is correlated with impaired wound healing, where a significant decrease in ...
