UN NUEVO APORTE A LA TOXICOLOGÍA DE COLORANTES ALIMENTARIOS: CONJUGACIÓN HEPÁTICA DE LA INDIGOTINA CON FOSFOLÍPIDOS
(Sociedad Chilena de Nutrición, Bromatología y Toxicología, 2005)
Composición de ácidos grasos en huevos y adultos de Tigriopus angulatus (Copepoda: Harpacticoida)
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2010)
How membrane lipids control the 3D structure and function of receptors
(AIMS Press, 2018)
Abstract: The cohabitation of lipids and proteins in the plasma membrane of mammalian cells is controlled by specific biochemical and biophysical rules. Lipids may be either constitutively tightly bound to cell-surface ...
Disclosure of cholesterol recognition motifs in transmembrane domains of the human nicotinic acetylcholine receptor
(Nature Research, 2011)
Abstract: Cholesterol influences ion-channel function, distribution and clustering in the membrane, endocytosis, and exocytic sorting of the nicotinic acetylcholine receptor (AChR). We report the occurrence of a cholesterol ...
The constellation of cholesterol-dependent processes associated with SARS-CoV-2 infection
(Elsevier, 2022)
Abstract: The role of cholesterol in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other coronavirus-host cell interactions is currently being discussed in the context of two main scenarios: i) the ...
Phylogenetic conservation of protein–lipid motifs in pentameric ligand-gated ion channels
(Elsevier B.V., 2015)
Abstract: Using the crosstalk between the nicotinic acetylcholine receptor (nAChR) and its lipid microenvironment as a
paradigm, this short overviewanalyzes the occurrence of structuralmotifswhich appear not only to be ...
The lipid habitats of neurotransmitter receptors in brain
(Elsevier B.V., 2016)
Abstract: Neurotransmitter receptors, the macromolecules specialized in decoding the chemical signals encrypted in the chemical signalingmechanism in the nervous system, occur either at the somatic cell surface of chemically ...
Cholesterol modulates acetylcholine receptor diffusion by tuning confinement sojourns and nanocluster stability
(Nature Research, 2018)
Abstract: Translational motion of neurotransmitter receptors is key for determining receptor number at the synapse and hence, synaptic efficacy. We combine live-cell STORM superresolution microscopy of nicotinic acetylcholine ...
Plasma lipid levels in 10-to 13-year old Costa Rican elementary schoolchildren
(2000-09)
An adverse lipid profile is a major risk factor for atherosclerosis. This study evaluated the lipid profiles of 683 schoolchildren aged 10 to 13 years. The prevalence of both high LDL and high total cholesterol levels was ...
