(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-06-01)The biopolymer chitosan was chemically modified by grafting polyacrylamide or polyacrylic acid in a homogeneous aqueous phase using potassium persulfate (KPS) as redox initiator system in the presence of N,N-methylene-bi ...
-
(PERGAMON-ELSEVIER SCIENCE, 2003-02-05)An HPLC reversed phase method using both UV (356 nm) and electrochemical (1000 mV) detection was developed in order to determine lercanidipine in commercial tablets. Repeatability and reproducibility were adequate. For ...
-
(Academic Press Inc., 1998)There is evidence that insulin-like growth factor-1 (IGF-1) plays a role in the development of left ventricular hypertrophy, but it is uncertain whether cardiac IGP-1 changes before or after hypertension is established, ...
-
(IOS Press, 2010)We describe the interactions of two benzimidazole derivatives, astemizole (AST) and lansoprazole (LNS), with anomalous aggregates of tau protein (neurofibrillary tangles). Interestingly, these compounds, with important ...
-
(Elsevier, 2013)Gold nanorods (AuNRs) stabilized by cetyltrimethylammonium bromide (CTAB) were deposited onto crystals of a-cyclodextrin (a-CD) inclusion compounds (ICs) that contained octanethiol (OT) as guest molecules. The nanodecoration ...
-
A selective voltammetric method to follow the hydrolytic degradation of nitrendipine and nisoldipine (WILEY-V C H VERLAG GMBH, 2001-12)The development and application of a differential pulse voltammetric procedure for the hydrolytic degradation kinetic study of two well-known 1,4-dihydropyridine type drugs, nitrendipine and nisoldipine are presented. The ...
-
(MUNKSGAARD INT PUBL LTD, 2000-04)Background/Aims: Low blood Se levels have been previously shown in normal pregnancies (third trimester) and significantly lower levels in patients with intrahepatic cholestasis of pregnancy (ICP), in Finland and in Chile, ...
-
(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 ...
-
(Sociedad Chilena de Química, 1998)The potential energy surface of hstamine monocation is calculated by MNDO types methodologies and by the Reaction Field model at CNDO/2 level, in order to rationalize the experimental findings about the relative abundance ...
-
(S. Karger AG, 2008)Many features of aging result from the incapacity of cells to adapt to stress conditions. When damage accumulates irreversibly, mitotic cells from renewable tissues rely on either of two mechanisms to avoid replication. ...
-
(2014)A hydrogen-terminated Si (111) surface was modified to form an aminoterminated monolayer for immobilization of streptavidin. Cleavage of an N-(ω- undecylenyl)-phthalimide covered surface using hidrazine yields an amino ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2004-06)Hybrid nanocomposites based on siloxane sols, chitosan and poly(monomethyl itaconate) (PMMI) as organic polymer counterparts were prepared. Tetraethyl ortosilicate was used as inorganic network fort-ning reagent that was ...
-
(2013)In this work, a new method to quantify nitrofurantoin in aqueous media using a flow injection system connected to commercially available screen-printed carbon nanofibers was developed. A pretreatment of the screen-printed ...
-
(AMER SOC PHOTOBIOLOGY, 2005-03)Thyronine derivatives are essential indicators of thyroid gland diseases in clinical diagnosis and are currently used as standards for developing ordinary biochemical assays. Photooxidation of gland hormones of the thyronine ...

-
(ELSEVIER SCIENCE SA, 2001-12-31)Detection of O-2((1)Delta(g)) phosphorescence emission, lambda(max) = 1270 nm, following laser excitation and steady state methods were employed to determine the total rate constant, k(T), for the reaction between the ...
-
(2013)The effect of a previous hydrostatic high-pressure (HHP) treatment on sensory and physical quality of chilled coho salmon (Oncorhynchus kisutch) was investigated. As a first stage, a 2(2) factorial design based on the ...
