Chronocoulometry diffusion coefficients as a measure of cyclodextrin-estradiol complex association (ELSEVIER SCIENCE SA, 2008-10-15)The formation of inclusion complexes between estradiol and p-cyclodextrin (CD), sulfobutyleter-beta-CD (SBCD) and hydroxypropil-beta-CD (HPCD) was studied by chronocoulometric and differential pulse voltammetry. In presence ...
-
(1996)The result obtained from different studies of the chronopharmacokinetics of some controlled-release tablets of theophylline are variable, since some authors report differences while others do not. At our laboratory we have ...

(Sociedad Chilena de Química, 1993)Este documento da una visión general del estado de esta disciplina, el que se elaboró a partir de la información solicitada a los investigadores del sistema universitario, estableciendo los Grupos de Investigación, sus ...
-
(Academia de Estudios Prof. Alfoso Leng, 1991)La evolución: un gran proceso creador y unificador. Los sistemas basados en grandes ideas unificadoras suelen asociarse, conciente o inconcientemente, con pensamientos o creencias acerca del destino humano y de su origen. ...
-
(Sociedad Chilena de Química, 1996)Se propone un método de análisis por inyección en flujo (FIA) con flujo interrumpido para la determinación simultánea de cobre y zinc. El método se basa en las diferentes velocidades en que se produce la reacción entre ...
-
(Frontiers Media, 2021)An increased risk of atrial fibrillation (AF) has been demonstrated in high-performance athletes. Soluble vascular adhesion molecule-1 (sVCAM-1), a biomarker involved in inflammation and cardiac remodeling, is associated ...
-
(GUSTAV FISCHER VERLAG, 1997-05)A light-dependent bleaching of plastids was induced in lemon seedlings through cultivation in the presence of the herbicide Norfluorazon (NFZ). Also, etiolated seedlings were obtained by cultivation under continuous dark ...
-
(Instituto de Tecnologia de Alimentos - ITAL, 2015)Betalains are fruit pigments possessing health-giving properties. To isolate the pigments, the juice must be separated from the fruit matrix, which contains biopolymers. The aim of this study was to clarify cactus pear ...

-
(1994)A cDNA clone coding for human protein kinase CK1 (casein kinase 1) has been isolated and sequenced demonstrating that it corresponds to a homolog of the CK1α form found in bovine brain. The derived amino acid sequence of ...
-
(SOC BIOLGIA CHILE, 2006)In this report we describe the isolation and characterization of a gene encoding the transcription factor Ace 1 (Activation protein of cup 1 Expression) in the white rot fungus Phanerochaete chrysosporium. Pc-ace 1 encodes ...
-
(ELSEVIER SCIENCE BV, 1998-01-12)A cDNA (MnP13-1) and the Cs-mnp1 gene encoding for an isoenzyme of manganese peroxidase (MnP) from C. subvermispora were isolated separately and sequenced. The cDNA, identified in a library constructed in the vector Lambda ...
-
(ELSEVIER SCIENCE BV, 1997-03-18)The cDNA, for xylanase B from Penicillium purpurogenum was cloned and sequenced. This DNA encodes a protein of 208 amino acids which is expected to yield a protein of 183 residues upon processing of the N terminus. The ...

(Royal Soc Chemistry, 2018-04-28)Gold nanoparticles with specific optical properties in combination with the CLPFFD peptide that exhibits selectivity for beta-amyloid (A beta) aggregates are promising photothermal absorbers for application in Alzheimer's ...
-
(Frontiers Media, 2021)We computationally explore an alternative to stabilize one-dimensional (1D) silicon-lithium nanowires (NWs). The Li12Si9 Zintl phase exhibits the NW 1 ∞[Li6Si5], combined with Y-shaped Si4 structures. Interestingly, ...
-
(Frontiers Media, 2022)Copper mining tailings are characterized by high concentrations of heavy metals and an acidic pH, conditions that require an extreme adaptation for any organism. Currently, several bacterial species have been isolated and ...
-
(Sociedad Chilena de Química, 2017)Hydrogen peroxide (H2O2) plays an important role as an intermediary in different biological, chemical and environmental systems. It has been widely used as an oxidizing and antimicrobial agent, in germicides production and ...
