Microbial and viral-like rhodopsins present in coastal marine sediments from four polar and subpolar regions
(Wiley Blackwell Publishing, Inc, 2017-01)
Rhodopsins are broadly distributed. In this work, we analyzed 23 metagenomes corresponding to marine sediment samples from four regions that share cold climate conditions (Norway; Sweden; Argentina and Antarctica). In order ...
Evidence of microbial rhodopsins in Antarctic Dry Valley edaphic systems
(Wiley Blackwell Publishing, Inc, 2017-09)
Microorganisms able to synthesize rhodopsins have the capacity to translocate ions through their membranes, using solar energy to generate a proton motive force. Rhodopsins are the most abundant phototrophic proteins in ...
Contributions of rhodopsin, cone opsins, and melanopsin to postreceptoral pathways inferred from natural image statistics
(Optical Society Of America, 2014-04)
Visual neural representation is constrained by the statistical properties of the environment. Prior analysis of cone pigment excitations for natural images revealed three principal components corresponding to the major ...
Memoria a través de difusión: Reproducibilidad en tiempos de respuesta a fotones individuales
(Universidad de los AndesMaestría en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2022-05-28)
Design and develop a simulation to describe the diffusion of molecules in the membrane of retinal rod cells, including simulating events in the cytoplasm, which describes the on/off process of the system. The fact that the ...
Retinal dysfunction in patients with chronic Chagas’disease is associated to anti-Trypanosoma cruzi antibodies that crossreact with rhodopsin
(Federation of American Societies for Experimental Biology, 2006-12)
To investigate retinal involvement in chronic Chagas' disease, we performed electroretinography and retinal fluorescein angiography studies in chagasic patients. Our results demonstrated a dissociated electrophysiological ...
Pigment epithelium-derived factor (PEDF) and derived peptides promote survival and differentiation of photoreceptors and induce neurite-outgrowth in amacrine neurons
(Wiley Blackwell Publishing, Inc, 2021-12-16)
Pigment epithelium-derived factor (PEDF) is a cytoprotective protein for the retina. We hypothesize that this protein acts on neuronal survival and differentiation of photoreceptor cells in culture. The purpose of the ...
The angiotensin II AT(1), receptor structure-activity correlations in the light of rhodopsin structure
(Amer Physiological Soc, 2007-04-01)
The most prevalent physiological effects of ANG II, the main product of the renin-angiotensin system, are mediated by the AT(1) receptor, a rhodopsin-like AGPCR. Numerous studies of the cardiovascular effects of synthetic ...
PHOTOMICROCALORIMETRY - PHOTOSUBSTITUTION OF CARBONYL BY PHOSPHITES IN [MN(ETA(5)C5H4CH3)(CO)(3)]

Carbon fixation and rhodopsin systems in microbial mats from hypersaline lakes Brava and Tebenquiche, Salar de Atacama, Chile
(Public Library of Science, 2021-02)
In this work, molecular diversity of two hypersaline microbial mats was compared by Whole Genome Shotgun (WGS) sequencing of environmental DNA from the mats. Brava and Tebenquiche are lakes in the Salar de Atacama, Chile, ...
