(MDPI, 2020)The P2X7 receptor is a ligand-gated, cation-selective channel whose main physiological ligand is ATP. P2X7 receptor activation may also be triggered by ARTC2.2-dependent ADP ribosylation in the presence of extracellular ...
-
(Universidad de Chile, 2019)La enzima convertidora de endotelina-1 (ECE-1) es una metaloproteasa de membrana encargada de la conversión del péptido Endotelina-1 a su forma activa. Presenta cuatro isoformas, las cuales solo difieren en sus extremos ...
-
(Springer, 2017-06)This study analyzed air quality in terms of the concentrations of sub-10 mu m (PM10) and sub-2.5 mu m particulate matter (PM2.5) recorded at 23 automated public monitoring stations located in 16 cities in south-central ...
-
(Public Library Science, 2020)Aim Exotic species' introductions together with extinction of native species represent the main mechanisms driving biotic homogenization of freshwater fish assemblages around the world. While generally ichtyofaunistic ...
-
(American Institute of Physics, 2020)We present a phenomenological procedure of dealing with the COVID-19 (coronavirus disease 2019) data provided by government health agencies of 11 different countries. Usually, the exact or approximate solutions of ...
-
(Universidad Autónoma Metropolitana de Iztapalapa, 2020)In the last years, the demand for natural products has increased. Different cacti species has demonstrated to be a source for the biosynthesis of secondary metabolites, as is the case of Coryphantha macromeris (Engelm.) ...
-
(IOP Publishing, 2020)Background: A major drawback in Alzheimer's disease (AD) is the lack of validated biomarkers for routine clinical diagnostic. We have reported earlier a novel blood biomarker, named Alz-tau (R), based on variants of platelet ...
-
(Royal Society Chemistry, 2017)Fluorescence spectroscopy with strong emitters is a remarkable tool with ultra-high sensitivity for detection and imaging down to the single-molecule level. Plasmon-enhanced fluorescence (PEF) not only offers enhanced ...
-
(1982)A method for investigating the polarizability change in the excited electronic states of nonpolar aromatic hydrocarbons from spectral solvent shifts has been developed. Comparisons with electrochromic measurements of ...
-
(UNAM, Fac. Ciencias Politicas & Sociales, 2020)The study of policies of memory regarding human rights violations in military dictatorships, armed conflicts and civil wars in recent world history has had an important boom in recent decades, constituting grounds for ...
-
(Nature, 2020)Mechanical properties of nanomaterials, such as nanowires and nanotubes, are an important feature for the design of novel electromechanical nano-architectures. Since grain boundary structures and surface modifications can ...
-
(2019-03)La transducción de olores en los cilios de las neuronas sensoriales olfatorias implica varias enzimas que requieren ATP. Existe evidencia que el ATP se genera por glicólisis en el lumen ciliar, utilizando glucosa incorporada ...
-
(Springer, 2020)Shifts in species distributions are among the observed consequences of climate change, forcing species to follow suitable environmental conditions. Using species distribution models (SDMs), we aimed at predicting trends ...
-
(The Royal Society, 2020)Vector-borne infectious disease dynamics result mainly from the intertwined effect of the diversity, abundance, and behaviour of hosts and vectors. Most studies, however, have analysed the relationship between host-species ...
-
(Wiley, 2020)In pursuit of socioeconomic development, many countries are expanding oil and mineral extraction into tropical forests. These activities seed access to remote, biologically rich areas, thereby endangering global biodiversity. ...
-
(Universidad de Chile, 2019-11)La erosión hídrica es un fenómeno natural que provoca el transporte del suelo y la perdida natural del mismo, sin embargo si esta pérdida de suelo no es compensada por medio de su regeneración, las características de ...
-
(BioMed Central, 2017)Background: Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature. Unfortunately, most ...
-
(Elsevier, 2020)The PyProcar Python package plots the band structure and the Fermi surface as a function of site and/or s,p,d,f - projected wavefunctions obtained for each k-point in the Brillouin zone and band in an electronic structure ...
-
(Taylor & Francis, 2020)The understanding of closed-shell interactions has become of tremendous relevance in the ever-growing field of supramolecular chemistry. Here, we present a theoretical study in which we characterised the intermolecular ...
-
(Elsevier, 2020)This review deals with the problem of designing safer solvents for chemical transformation and chemical processes. These materials generically defined as neoteric solvents include the well known ionic liquids (ILs) and ...
