Hydrolytic degradation of nitrendipine and nisoldipine
(PERGAMON-ELSEVIER SCIENCE, 2002-06-01)
The development of a new HPLC-UV diode array procedure applied to follow the hydrolytic degradation of two well-known 4-nitrophenyl-1,4-dihydropyridine derivatives, nitrendipine and nisoldipine is reported. Hydrolysis of ...
Potato tuber isoapyrases: Substrate specificity, affinity labeling, and proteolytic susceptibility
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-05)
Apyrase/ATP-diphosphohydrolase hydrolyzes di- and triphosphorylated nucleosides in the presence of a bivalent ion with sequential release of orthophosphate. We performed studies of substrate specificity on homogeneous ...
Removal of metal ions from aqueous solutions by sorption onto microcapsules prepared by copolymerization of ethylene glycol dimethacrylate with styrene
(ELSEVIER, 2008-11-03)
The removal of Cd(II) and Cu(II) ions from aqueous solutions was studied by sorption onto microcapsules prepared by copolymerizing ethylene glycol dimethacrylate (EGDMA) and styrene (ST). The microcapsules were prepared ...
Self-assembled multilayers of polyethylenimine, DNA and gold nanoparticles. A study of electron transfer reaction
(Elsevier, 2010)
The present manuscript describes studies of the electron transfer kinetics at gold electrodes modified by electrostatic self-assemblies of polyethylenimine (PEI), DNA and gold nanoparticles (NP) by Scanning
Electrochemical ...
Recent developments in the electrochemistry of some nitro compounds of biological significance
(BENTHAM SCIENCE PUBL, 2005-04)
The redox chemistry of different nitro compounds of biological significance is focused to understand how the reduction of the nitro group can play an active role in several aspects as: electroanalytical determinations, ...
Ca2+-dependent K+ channels from rat olfactory cilia characterized in planar lipid bilayers
(ELSEVIER SCIENCE BV, 2005-03-14)
Olfactory cilia contain cyclic nucleotide-gated and Ca2+-dependent Cl- conductances that underlie excitatory chemotransduction, and a Ca2+-dependent K+ (K-Ca) conductance, apparently involved in inhibitory transduction. ...
Substituent effect of side chains on the photochemical behavior of a new generation 1,4-dihydropyridine: Lercanidipine
(Elsevier Science SA, 2018)
Lercanidipine (LERCA) is a third generation antihypertensive drug belonging to the 1,4-dihydropyridine's family, which has been reported to induce photoallergic and/or phototoxic effects in patients with long term treatment. ...
Potentiodynamic Behavior of Carbon Steel in Borate Buffer Solutions under Different Hydrodynamic Conditions
(Electrochemical Society, 2016)
The corrosion and passivation behavior of carbon steel AISI 1020 in borate buffer pH 8.4 were
studied in terms of a superposition model for corrosion partial reactions, applied for experimental
polarization curves measured ...
Comparison of low-cost two-equation turbulence models for prediction flow dynamics in twin-jets devices
(2007)
The flow field of a turbulent twin plane jet impinging normally onto a flat surface was investigated numerically for two configurations: a non-recirculating double jet at Re= 14,000 and a partially recirculated double jet ...
Solvent effects in ionic liquids: Empirical linear energy-density relationships
(2012)
Multiparameter linear energy-density relationships to model solvent effects in room temperature ionic liquids (RTILs) are introduced and tested. The model incorporates two solvent dependent and two specific solute-solvent ...
