-
(ELSEVIER, 2010)Substantial progress has been made throughout the last decades in the elucidation of the key players and mechanisms responsible for Ca2+ signal generation in both excitable and non-excitable cells. Importantly, these ...
-
(SPRINGER VERLAG, 1998-01)Heavy metals participate in complex biogeochemical cycles whose final destination (except on a geological scale)is the bottom of oceans and lakes. This implies that to reach the bottom the metals of the sediment have to ...
-
(Universita degli Studi di Pisa, Istituto di Chimica Agraria, 1992)Wasterwastes of municipal and industrial origin used to irrigate farmlands contain heavy metals which are sorbed on the surfaces of soil particles. Among those metals are cadmium (Cd) and copper(Cu). The degree to which ...
-
(Elsevier, 2013)Ceramides are important intermediates in the biosynthesis and degradation of sphingolipids that regulatenumerous cellular processes, including cell cycle progression, cell growth, differentiation and death. In ...
-
(1997)In toad olfactory neurons, a putrid odorant mixture inducing inhibitory responses increases Ca2+-activated K+ conductance, developing a hyperpolarizing receptor potential. Removal of extracellular Ca2+ or exposure to ...
-
(Wiley, 2017-04)Calcium (Ca2+) is a key player in the regulation of many cell functions. Just like Ca2+, mitochondria are ubiquitous, versatile, and dynamic players in determining both cell survival and death decisions. Given their ...
-
(Sociedad Chilena de Nutrición, Bromatología y Tecnología, 1982)The evaluation of the sensorial quality of tea was developed in order to complement the information obtained from physico-chemical analysis performed on different types of tea. The work was carried on with 12 samples, ...
-
(ELSEVIER SCIENCE BV, 2010-03)Type-2 ryanodine receptors (RyR2) - the calcium release channels of cardiac sarcoplasmic reticulum - have a central role in cardiac excitation-contraction coupling. In the heart, ischemia/reperfusion causes a rapid and ...
-
Capillary electrophoretic determination of ions in soils / determinación de iones en suelos por ... (SOCIEDAD CHILENA DE QUIMICA, 1997-12)The applicability, sensitivity and repetitivity, as well as general aspects of the Capillary Zone Electrophoresis (CZE) technique was studied as applied in the identification and quantification of Cl-, NO3-, HCO3-, SO42-, ...
-
(ELSEVIER SCI LTD, 2002-03)Capillary zone electrophoresis (CZE) was used to study the effect of frozen storage on the electrophoretic patterns of sarcoplasmic proteins (SAR) extracted from fillets of golden kinglip (Genypterus blacodes) species using ...
-
(Springer, 2016)Highly fluorescent nanoparticles, or quantum dots, have multiple applications in biology and biomedicine; however, in most cases, it is necessary to functionalize them to enhance their biocompatibility and selectivity. ...
-
(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 ...
-
(Royal Society of Chemistry, 2020)We synthesized an anthracene derivative with solvatochromic properties to be used as a molecular probe for membrane dynamics and supramolecular organization. A nine carbon atom acyl chain and a dimethylamino substitution ...
-
(INST GRASA SUS DERIVADOS, 2008-01)Se analizan las características generales del coquito de palma chilena y se estudia con detalle la composición de su aceite. Con este objetivo, se analizan 4 lotes de coquitos procedentes de las dos regiones de Chile ...
-
(Elsevier, 2015)tA simple and sensitive electrochemical method using pretreated carbon nanofiber screen printed elec-trodes joined to a flow injection analysis (CNF-SPE-FIA) system was developed to analyze nimodipine(NMD) in pharmaceutical ...
-
(2012)The inhibition of aggregation and disaggregation effect of a β-sheet breaker was evaluated by in situ electrochemistry of the Aβ 1-42 peptide. The exposition of 10tyr residue was followed using a carbon nanotubes modified ...
-
(Elsevier, 2016)We report for the first time the use of glassy carbon electrodes (GCE) modified by drop-coating with multi-walled carbon nanotubes (MWCNTs) dispersed in cytochrome c as platform for the construction of bienzymatic biosensors, ...
-
(Springer, 2018-05)The objective of the present study was to synthesize sodium carboxymethylcellulose from Eucalyptus nitens cellulose. The cellulose extraction was carried out in three stages. In the first stage, E. nitens wood was fractionated ...
-
(Elsevier, 2015)Cardiac fibroblasts (CF) not only modulate extracellular matrix (ECM) proteins homeostasis, but also respond to chemical and mechanical signals. CF express a variety of receptors through which they modulate the proliferation/cell ...
-
(the European Society of Cardiology, 2013)Aims Chaperone-mediated autophagy (CMA) is a selective mechanism for the degradation of soluble cytosolic proteins bearing the sequence KFERQ. These proteins are targeted by chaperones and delivered to lysosomes where ...
