(American Chemical Society, 2020)In this work, we report a new octanuclear cluster based on FeIII and the ligand 1H-imidazole-4,5-dicarboxylic acid, [Et3NH](12)[Fe-8(IDC)(12)]center dot 10DMF center dot 13H(2)O (1), with a metal core containing eight ...
-
(MDPI, 2022)In this work, we report the obtaining of new hybrid nanocomposites with catalytic activity formed by nanofibers of polymer blends and gold nanoparticles. The nanofibers were obtained by electrospinning blends of a poly ...

(SOCIEDAD CHILENA DE QUIMICA, 2006-03)In QSRR discipline an easy novel to used parameter was designed (Vc) for evaluated classical topological index (W, (1)chi, Z, MTI) and two new generation ones (Xu, (1)chi(h)). Regression between Vc and (1)chi(h) presented ...
-
(Elsevier, 2014)Insulin-like growth factor 1 (IGF-1) signaling regulates contractility, metabolism, hypertrophy, autophagy, senescence, and apoptosis in the heart. IGF-1 deficiency is associated with an increased risk of cardiovascul ...
-
(Frontiers Media, 2022)Down syndrome (DS) is a genetic disorder caused by a trisomy of the human chromosome 21 (Hsa21). Overexpression of Hsa21 genes that encode proteins and non-coding RNAs (ncRNAs) can disrupt several cellular functions and ...
-
(Frontiers Media S.A., 2016-04)Type 2 diabetes mellitus (T2DM) is a highly prevalent disease worldwide. Cardiovascular disorders generated as a consequence of T2DM are a major cause of death related to this disease. Diabetic cardiomyopathy (DCM) is ...
-
(ROYAL SOC CHEMISTRY, 2012)In the search for new therapeutic tools against neglected diseases produced by trypanosomatid parasites, and particularly against African Trypanosomiasis, whose etiological agent is Trypanosoma brucei, organoruthenium ...
-
(2007)Two new phenolic esters 9-trans-p-coumaroyloxy-α-terpineol (1) and 7-trans-p-coumaroyloxy-taedol (2), both endowed with free radical scavenger activity and cleroda-3,13 (E)-dien-15,18-diol (3) for which a cis stereochemistry ...

-
(PERGAMON-ELSEVIER SCIENCE LTD, 2009-12-15)New 5-nitroindazole derivatives were developed and their antichagasic properties studied. Eight compounds (14-18, 20, 26 and 28) displayed remarkable in vitro activities against Trypanosoma cruzi (T. cruzi). Its unspecific ...
-
(MDPI, 2021)The activation of the human cannabinoid receptor type II (CB2R) is known to mediate analgesic and anti-inflammatory processes without the central adverse effects related to cannabinoid receptor type I (CB1R). In this work ...
-
(Elsevier, 2008)A new quaternary alkali metal, rare earth thiophosphate was synthesized by the ceramic method and characterized by single crystal X-ray diffraction: K2SmP2S7 crystallizes in the monoclinic space group C2 (no. 5) with the ...
-
(MDPI, 2021)There is an urgent need for the development of new antibiotics. Here, we describe the inhibitory activity of new quinone compounds against methicillin-resistant Staphylococcus aureus (ATCC(R) 43300), methicillin-sensitive ...
-
(Microextraction Techniques, 2014)A novel extraction approach was developed based on rotating-disk sorptive extraction (RDSE). In this approach the rotating-disk extraction device consists of a Teflon disk, with a cavity that is loaded with a commercial ...
-
(TAYLOR & FRANCIS LTD, 1996-01)A synthetic route has been developed to a new series of homo- and co-polysiloxanes with a terminal chiral 2-(S)-butyl fragment attached to the mesogenic biphenyl core via the ketone binding group, >C=O. The synthesis, ...
