Effects of circadian rhythm and cAMP on retinomotor movements in the green sunfish, Lepomis cyanellus.
The photoreceptors and retinal pigmented epithelium (RPE) of teleosts undergo diurnal changes in position in response to day/night changes in light conditions. These position changes, called retinomotor movements, may also persist under conditions of constant darkness. In this study, the authors have compared the retinomotor movements of rods, cones, and RPE under conditions of constant darknes...

متن کاملLight-induced photoreceptor shedding in teleost retina blocked by dibutyryl cyclic AMP.
In retinas of lower vertebrates, at least two retinal phenomena appear to be closely tied to the diurnal light-dark cycle: photoreceptor renewal and retinomotor movements. The authors have previously reported that treatments that elevate retinal cyclic AMP levels induce dark-adaptive retinomotor movements. In the present study, the authors have tested whether cyclic nucleotides might also inhib...
متن کاملOn the physiology of melanophores in the marine isopod, Idotea japonica. I.
Since Matzdorff (1883) found that the color of Idotea tricuspidata altered in response to conditions of background, a number of experiments have been carried out concerning the chromatophore physiology in isopods. There workers were unanimous in concluding that the chromatophores of isopods showed background adaptation, and, that some species showed diurnal rhythm in melanophore condition. It h...
متن کاملAssessment of Circadian Rhythmicity of Respiratory Determinants Related to Diurnal Activities of Children and Adolescents: A Case Study in the City of Isfahan
Background: Diurnal sequences of activities conducted at several locations visited by individuals have an impact on population exposure to air pollution. However, data on individual's movement with a fine time resolution is rare. Methods: In the current study, 399 children and adolescents (aged 11–18 years) from Isfahan city were asked to recall their 24-hour diary during winter and spring 2014...
