(1996)The transport of copper from EI Teniente's mine waters by solvent extraction in a membrane extractor using a hollow fiber as solid support as solid support has been studied. LIX-860, a salicylaldoxime was used as carrier. ...
-
(1985)We report results of Xα valence bond scattered wave (Xα-VB-SW) calculations for a variety of clusters that mimic the active sites in iron-sulfur proteins: Fe(SR)41-,2- (R = H, CH3), Fe2S2(SH)42-,3-, and Fe4S4(SCH3)42-,3-. ...
-
(WILEY-V C H VERLAG GMBH, 1998-11)Functionalization of isotactic poly(propylene) (PP) with dimethyl itaconate (DMI) as functional polar monomer using 2,5-dimethyl-2,5 -bis(tert-butylperoxy)hexane (L101) as radical initiator was carried out in both boiling ...

(PERGAMON-ELSEVIER SCIENCE LTD, 2006-07-10)A group of dinuclear copper(II) compounds containing the macrocyclic complexes Cu2L2+ (LH2 = C(24)H(2)sN(4)O(4): a ligand derived from the condensation of 4-methyl-2,6-diformylphenol with 1,3-diamine-2-propanol) have been ...
-
(Royal Society of Chemistry, 2010)A novel iridium complex incorporating a di(2-picolyl)anilino-appended bipyridine ligand was synthesized and its optical properties studied. The presence of Zn2+ ions specifically perturbs the excited state, giving rise to ...
-
(1992)In this work the microsomal lauric acid ω-hydroxylation, fatty acid peroxisomal β-oxidation, and the levels of cytochrome P-450 IVAI were studied in liver tissue from starved rats. Starvation increased the peroxisomal ...
-
(2016)The vascular endotheliumplays an essential role in the control of the blood flow. Pharmacological agents like quinone (menadione) at various doses modulate this process in a variety of ways. In this study, Q7, a ...
-
(2011)Broussonetia papyrifera (L.) Vent. (Magnoliophyta: Urticales), or paper mulberry, is a species of Asian origin dispersed by humans throughout the Pacific. Our aim is to evaluate the genetic variability of this plant in ...
-
(Springer Netherlands, 2019)Alstroemeria is a genus native to South America from which many varieties of ornamental plants have been developed and introduced into the market. Interspecific hybridization followed by embryo rescue has been one of the ...
-
(Elsevier B.V., 1996)Molecular characterisation of a lytic thermoactive β-1,3-glucanase from Oerskovia xanthineolytica LL-G109 has been performed. A molecular mass of 27 195.6 ± 1.3 Da and an isoelectric point of 4.85 were determined by ...
-
(2009)Four different 5-nitroindazole derivatives (1-4) and its inclusion with Heptakis(2,6-di-O-methyl)-beta-cyclodextrin (DM beta CD) were investigated. The stoichiometric ratios and stability constants describing the extent ...
-
(2005)We examined the genetic makeup of 221 HIV-1 strains from Chilean persons living with HIV/AIDS by HMA and DNA sequencing of the env gene: 143 cases were infected by sexual contact with an already-infected partner, 76 were ...
-
(Elsevier Ltd, 2018)© 2018 Elsevier B.V. High demand for silver nanoparticles due to their extensive applications in different field has raised need of eco-friendly green synthesis with determined biomedical effects. This study proposes a ...

-
(Blackwell Publishing Ltd, 2019)(R/S)-Salsolinol is a full agonist of the μ-opioid receptor (μOR) Gi protein pathway via its (S)-enantiomer and is functionally selective as it does not promote β-arrestin recruitment. Compared to (S)-salsolinol, the ...
-
(2004)The effects of electric fields on hydrogen bonding in ammonia-formic acid system, are examined with STO-3G and 6-31 G(d) wavefunctions. This system was used in a previous work to model hydrogen bonding in crystalline amino ...
-
(Elsevier, 2015)The microextraction of diclofenac and mefenamic acid from water samples was performed by using rotating disk sorptive extraction (RDSE) with molecularly imprinted polymer (MIP) as the sorptive phase. The MIP was synthesized ...
