ABSTRACT Purpose Evaluate blue-violet light filter and additional power of +0.40 D in the near zone ophthalmic lenses, on convergence, accommodative functions, and symptoms of digital asthenopia (DA). Methods Randomized study in cross-over design conducted on 49 volunteers (age, 29 ± 5.5 years; male...
Abstract Silver nanoparticles (AgNPs) are among the most known nanomaterials being used for several purposes, including medical applications. In this study, Calendula officinalis L. flower extract and silver nitrate were used for green synthesis of silver nanoparticles under red, green and blue light-em...
Los ritmos circadianos modulan prácticamente todos los procesos fisiológicos en los mamíferos y estos al estar sincronizados con sus ritmos circadianos garantizan su salud. Obviamente una alteración circadiana puede ser el origen de una amplia gama de enfermedades. La invención de la luz artificial ...
BACKGROUND: Molecular brain therapies require the development of molecular switches to control gene expression in a limited and regulated manner in time and space. Light-switchable gene systems allow precise control of gene expression with an enhanced spatio-temporal resolution compared to chemical induc...
El color es un efecto visual de los rayos de luz reflejándose y su concepto
es complejo por ser una sensación que se percibe y por las características
electromagnéticas. Los dientes varían espacialmente porque son curvados,
tienen prolongaciones relativamente pequeñas y vistas en contra de
una vari...
Fungi are capable of sensing light from ultraviolet to far-red and they use light as a source of information about the environment anticipating stress and adverse conditions. Lentinus crinitus is a lignin-degrading fungus which produces laccase and other enzymes of biotechnological interest. The effect o...
O romance Mrs. Dalloway, escrito pela inglesa Virginia Woolf (1882-1941), é um marco na literatura universal por apresentar um novo formato na arte da escrita intitulado fluxo de consciência. Esta forma estilística visa descrever as falas e os pensamentos dos personagens por meio do discurso indireto ...
BACKGROUND: Although bioactive metabolites capable of causing oxidative photo-necrosis in plant tissues have been identified in fungi, little is known about this type of mechanism in bacteria. These metabolites act as photosensitizers that generate reactive oxygen species (ROS) capable of causing damage ...
