(Universidad de Santiago de Chile, 2014)The estrous cycle disruptor effect of an ethanolic extract (EMATst) from Buddleja globosa leaves and standardized in its main component (verbascoside) was determined in rats after the subcutaneous administration of EMATst. ...
-
(Bentham Science Publishers B.V., 2014)In this article we review the flow chemistry methodologies for the controlled synthesis of different kind of nano and microparticles for biomedical applications. Injection mechanism has emerged as new alternative for the ...
-
(Taylor and Francis Inc., 2014)Pharmacological activation of autophagy is becoming an attractive strategy to induce the selective degradation of aggregate-prone proteins. Recent evidence also suggests that autophagy impairment may underlie the pathogenesis ...
-
(Lippincott Williams and Wilkins, 2014)BACKGROUND:: Little is known about the biological effects of angiotensin-(1-9), but available evidence shows that angiotensin-(1-9) has beneficial effects in preventing/ameliorating cardiovascular remodeling. OBJECTIVE:: ...
-
(2012)Potato chips were classified in quality categories according to their color after frying at oil temperatures (120, 140, 160, and 180 ± 1 °C) and undergoing some pre-treatments (control or unblanching, blanching, and blanching ...
-
(Sociedad Chilena de Quimica, 2013)As (III) was determined by differential pulse polarography (DPP) in 1 mol L-1 HCl as supporting electrolyte. For quantification, the -0.35 V peak (versus Ag/AgCl) was chosen. The obtained detection and quantification limits ...
-
(American Scientific Publishers, 2013)With the purpose of obtaining stable and non-toxic nanocomposites with potential biomedical applications we coated gold nanoparticles (AuNP) with chitosan (CHI) and CHI grafted with poly(Nisopropilacrylamide) (PNIPAAm) and ...
-
(2014)The present study is focused on the characterization of the interaction between (-)-epigallocatechingallate (EGCG) and cyclodextrins like β-cyclodextrin (βCD), heptakis(2,6 di-O-methyl)-β-cyclodextrin (DMβCD), and ...
-
(American Scientific Publishers, 2013)There has been an increase in the research towards the use of nanoparticles as a promising tool for nanomedicine, from imagenology, drug and gene delivery, to phototherapy. Little is known regarding the interaction between ...
-
(2013)ABSTRACT Chloride selective polymeric liquid membrane electrode has been developed by using Bis-(2-ethylhexyl) Sebacate (DOS) as plasticizer and 2-[5-(4-nitrophenyl) furyl]-4,5-diphenyl imidazole (FFDFIN) as ionophore. ...
-
(2014)In this paper, for the first time, an electro-analytical method based on the direct adsorption of double-stranded deoxyribonucleic acid (dsDNA) at glassy carbon electrode modified with ethylendiamine (eda)functionalized ...
-
(2013)A novel ORAC (oxygen radical absorbance capacity) assay to assess antioxidant capacity of phenolic compounds in near-gastric conditions (pH 2.0) is presented. AAPH (2,2'-azo-bis(2-amidinopropane)dihydrochloride) was used ...
-
(2013)O objetivo deste estudo foi utilizar a técnica de difusão em filmes finos por gradiente de concentração (DGT) para a avaliação da disponibilidade de cobre em solos com elevados níveis do metal, que foi alterado com ...
-
(2012)We report the adsorptive voltammetric determination of nifedipine on multiwalled carbon nanotubes (MWCNT)-modified glassy carbon electrode (GCE). Nifedipine was adsorbed on the MWCNT and then reduced using linear sweep and ...
-
(2014)The stopping power of palladium for protons has been measured using the transmission method with an overall uncertainty of around 5% over the energy range Ep=(0.300-3.100) MeV. These stopping power data are then compared ...
-
(2013)This paper describes the investigation and development of a novel magnetic drug delivery nanosystem (labeled as MO-20) for cancer therapy. The drug employed was oncocalyxone A (onco A), which was isolated from Auxemma ...
-
(Sociedad Chilena de Quimica, 2013)In recent years there has been a great demand for rare earth metals because of their unique physical and chemical properties as new constituents for electronic, optical and magnetic devices. Because of their extremely ...
-
(2013)In the structure of the title compound, {[Cu-2(C10H2O8)-(H2O)(6)]center dot 4H(2)O}(n), the benzene-1,2,4,5-tetracarboxylate ligand, (btec)(4-), is located on a crystallographic inversion centre in a 4-coordination mode. ...
-
(Sociedad Chilena de Quimica, 2013)Silicone rod extraction (SR) is a siloxane-based methodology for the extraction of organic pollutants from aqueous samples with similar principle extraction as the stir bar sorptive extraction (SBSE). In this study the SR ...
-
(Taylor and Francis Inc., 2013)Despite recent scientific and technological advances, cardiovascular disease remains the leading cause of morbidity and mortality worldwide. Autophagy, an evolutionarily ancient response to cellular stress, has been ...
