(ELSEVIER, 2008-11-03)The removal of Cd(II) and Cu(II) ions from aqueous solutions was studied by sorption onto microcapsules prepared by copolymerizing ethylene glycol dimethacrylate (EGDMA) and styrene (ST). The microcapsules were prepared ...
-
(1997)We studied the effects of chronic exposure to malathion in the kidney of Octodon degus, a caviomorph whose habitat may be exposed to pesticides currently used in Chilean agriculture. A group of adult female animals received ...
-
(Elsevier, 2013)Fluoxetine is currently being administered for long-term maintenance and for prophylactic reasons following the remission of depressive symptoms and several other psychiatric and neurological conditions. We have previously ...
-
(AMER CHEMICAL SOC, 2006-07-05)The results presented here show that elementary design enhancements have led to a 20-fold increase in the cellular uptake properties of a Pro-rich cell-penetrating peptide. These results are relevant not only due to the ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2005-12)The catalysis of the hydroesterification and hydroformylation-acetalization of 1-hexene by rhodium(I), cis-[Rh(CO)2(amine)2](PF6) complexes (amine = pyridine, 2-picoline, 3-picoline, 4-picoline, 3,5-lutidine or 2,6-lutidine) ...
-
(Springer, 2022)Santiago, capital city of Chile, presents air pollution problems for decades mainly by particulate matter, which significantly affects population health, despite national authority efforts to improve air quality. Different ...
