Retinal photoreceptors of two subterranean tuco-tuco species (Rodentia, Ctenomys): Morphology, topography, and spectral sensitivity
(Wiley-liss, Div John Wiley & Sons Inc, 2010-10)
Traditionally, vision was thought to be useless for animals living in dark underground habitats, but recent studies in a range of subterranean rodent species have shown a large diversity of eye features, from small ...
Identificación funcional de una nueva opsina como fotopigmento
(2015-12-08)
El análisis de secuencias de elementos involucrados en fotorecepción ha revelado la existencia de una nueva subfamilia de opsinas (Gr4), posiblemente acopladas a una proteína Go. Se ha sugerido que estas proteínas participan ...
Genome-enabled insights into the biology of thrips as crop pests
(BioMed Central, 2020-12)
Background: The western flower thrips, Frankliniella occidentalis (Pergande), is a globally invasive pest and plant virus vector on a wide array of food, fiber, and ornamental crops. The underlying genetic mechanisms of ...
Avaliação da autofagia, senescência celular e expressão de OPN3 na pele com melasma em comparação com a pele sã adjacente
(Universidade Estadual Paulista (Unesp), 2020-11-25)
Melasma é uma doença crônica, que acomete principalmente mulheres durante o menacme. As lesões ocorrem exclusivamente em áreas fotoexpostas (especialmente a face), sendo a radiação ultravioleta (RUV) o principal desencadeante ...
Melanopsin and the Non-visual Photochemistry in the Inner Retina of Vertebrates
(Wiley Blackwell Publishing, Inc, 2016-01)
Melanopsin (Opn4), a member of the G-protein-coupled receptor family, is a Vitamin A-based opsin in the vertebrate retina that has been shown to be involved in the synchronization of circadian rhythms, pupillary light ...
Lutein and Zeaxanthin Protect Photoreceptors from Apoptosis Induced by Oxidative Stress: Relation with Docosahexaenoic Acid
(Association for Research in Vision and Ophthalmology, 2007-11)
Purpose: Oxidative stress has been proposed as a major pathogenic factor in age-related macular degeneration (AMD), the leading cause of vision loss among elderly people of western European ancestry. Lutein (LUT) and ...
The pineal complex: a morphological and immunohistochemical comparison between a tropical (Paracheirodon axelrodi) and a subtropical (Aphyocharax anisitsi) characid species
(Wiley-liss, Div John Wiley & Sons Inc, 2016-10)
Cardinal neon Paracheirodon axelrodi and bloodfin tetra Aphyocharax anisitsi are two species of characids with high trade value as ornamental fish in South America. Although both species inhabit middle water layers, cardinal ...
Un tercer tipo de cascada de fototransducción
(2013)
Tradicionalmente los fotorreceptores animales se han dividido en 1-ciliados, que se hiperpolarizan con la luz y transducen mediante una proteína Gt; y 2-rabdoméricos, que son despolarizantes y utilizan una proteína Gq. En ...
