(Sociedad Chilena de Química, 2014)We report a voltammetric study of several nitroaromatic compounds such as the drugs: Nifedipine, Nitrendipine, Furnidipine and Nisoldipine in multiwalled carbon nanotubes (MWCNT) modified electrodes. All the compounds are ...
-
(MDPI, 2022)Major advances in sequencing technologies and targeted therapies have accelerated the incorporation of oncology into the era of precision medicine and "biomarker-driven" treatments. However, the impact of this approach on ...
-
(LIPPINCOTT WILLIAMS & WILKINS, 2003-08)Genetic factors influence alcohol consumption and alcoholism. A number of groups have bred alcohol drinker and non drinker rat strains, but genetic determinants remain unknown. The University of Chile rat lines UChA (low ...
-
(Elsevier, 2017)Myelin basic protein (MBP) is a key component of myelin, the specialized lipid membrane that encases the axons of all neurons. Both plasminogen (Pg) and tissue-type plasminogen activator (t-PA) bind to MBP with high ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-08)Changes in N-distribution patterns in volcanic-ash of Chile after deforestation of a primary forest were measured. There is a clear tendency towards the depletion of N linked to high molecular weight fractions (humin, humic ...

(Sociedad Chilena de Quimica, 2017)© 2017 Sociedad Chilena de Quimica. All rights reserved. Single crystals of 1,3-bis(cyanomethoxy)calix[4]arene (1) were grown from Chloroform/Methanol mixture and these were nanodecorated with colloidal gold nanoparticles ...
-
(Future Medicine Ltd., 2016)Current strategies for brain diseases are mostly symptomatic and noncurative. Nanotechnology has the potential to facilitate the transport of drugs across the blood-brain barrier and to enhance their pharmacokinetic ...
-
(AMER CHEMICAL SOC, 2006-01)The local heat delivered by metallic nanoparticles selectively attached to their target can be used as a molecular surgery to safely remove toxic and clogging aggregates. We apply this principle to protein aggregates, in ...
-
(Frontiers Media, 2021)Urinary tract infection (UTI) is one of the most common reasons for antibiotic treatment. Nevertheless, uropathogens are steadily becoming resistant to currently available therapies. In this context, nanotechnology emerges ...
