-
(Accademia Nazionale dei Lincei, 1971)From the stem bark of Strychnos Romeu Belenii Krukoff & Barneby a Loganiacea of South America, a new indolinic alkaloid has been isolated, to which the structure of II-methoxydiaboline(I) has been assigned on the basis of ...
-
(NATURE PUBLISHING GROUP, 2010-02-03)In response to stress, cells start transcriptional and transcription-independent programs that can lead to adaptation or death. Here, we show that multiple inducers of autophagy, including nutrient depletion, trigger the ...
-
(Taylor and Francis Inc., 2010)Cells respond to stress by activating cytoplasmic mechanisms as well as transcriptional programs that can lead to adaptation or death. Autophagy represents an important cytoprotective response that is regulated by both ...
-
(Pergamon-Elsevier Science LTD, 2018)This work is focused on the critical analysis of the non-covalent modification of a thiolated-gold surface with different grapheneous materials and the covalent attachment of bovine serum albumin (BSA) as a model protein. ...
-
(Elsevier, 2014)Immobilization of rhodamine 6G in calcium alginate microcapsules was achieved using the polyanion bearing negatively charged aromatic groups poly(sodium 4-styrenesulfonate) as complexing agent. The immobilization of the ...
-
(AMER CHEMICAL SOC, 1996-05-15)The roles of chemical kinetics and mass transfer in two types of bioreactors (packed-column reactors and rotating disk bioreactors), used with continuous-now sample/reagent(s) processing, are discussed in detail. A normalized ...
-
(MDPI, 2015)This paper aims to analyse the economy-wide implications of a carbon tax applied on the Chilean electricity generation sector. In order to analyse the macroeconomic impacts, both an energy sectorial model and a Dynamic ...
-
(MDPI, 2021)The aim of this work was to study the impact of the methodology of in vitro gastric digestion (i.e., in terms of motility exerted and presence of gastric emptying) and gel structure on the degree of intestinal proteolysis ...
-
(Elsevier, 2020)In order to determine the possible non-covalent influence of the alkali metal cation on the electrooxidation of 1-heptanol on gold in alkali metal hydroxides, 0.1 M MOH solutions, where M = Li, Na, K, Rb, and Cs, have been ...
-
(Universidad de chile, 1985)
-
(Sociedad Chilena de la Ciencia del Suelo, 2000)Entre los principales intereses mundiales hoy se tiene la gran conciencia del resguardo y recuperación de nuestros principales recursos naturales, entre los cuales es fundamental el sistema edáfico. Los suelos, con fines ...
-
(MARCEL DEKKER INC, 2003)Treatment of formylchromones, dissolved in 2-propanol with basic alumina at 75degreesC, selectively reduces the formyl group with good yields without any activation process of the alumina.
-
(Royal Society of Chemistry, 2018)A recombinant laccase from thermophilic bacteria was used to construct an enzyme-multi-walled carbon nanotube composite catalyst, which shows improved stability as a bio-electrocatalyst for the oxygen reduction reaction ...
-
(MDPI, 2020)Ezetimibe (EZ) is a poorly water-soluble drug with low bioavailability. Strategies such as solid dispersions (SD) and micellar systems (MS) were developed to identify the most effective drug delivery formulations with the ...
-
(2009)The slightly water-soluble flavonoid galangin (G) and its inclusion with either β-cyclodextrin (βCD), hydroxypropyl-β-cyclodextrin (HPβCD) or Heptakis-2,6-O-di methyl-β-cyclodextrin (DMβCD) were investigated. The stoichiometric ...
-
(Dove Medical Press, 2020)Introduction: Gold nanorods are highly reactive, have a large surface-to-volume ratio, and can be functionalized with biomolecules. Gold nanorods can absorb infrared electromagnetic radiation, which is subsequently dispersed ...
-
(Future Medicine, 2017)Aim: To improve the in vivo delivery of gold nanorods (GNRs) to the central nervous system of rats, these gold nanoparticles were conjugated to Angiopep-2, a shuttle peptide that can cross the blood-brain barrier. Materials ...
-
(2010)Background & aims: Gold nanoparticles (GNPs) have promising applications for drug delivery as well as for the diagnosis and treatment of several pathologies, such as those related to the CNS. However, GNPs are retained in ...
-
(Wiley-VCH Verlag, 2019)A novel and useful method to catalyze the electro-oxidation of nicotinamide adenine dinucleotide (NADH) over a glassy carbon electrode (GCE) modified with graphene oxide (GO) is presented. Based on the presence of oxygen ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-09-15)The in vitro growth inhibition activity of new thiosemicarbazone derivatives against the protozoan parasite Trypanosoma cruzi, the causative agent of American trypanosomiasis, are described. The designed compounds combine ...
