...V. Benno Meyer-Rochow The retina of the Antarctic teleost Trematomus bernacchii was examined immunocytochemically, using antisera against bovine rhodopsin (1:1,000) and visinin (1:250). There were no surprises with regard to rhodopsin, but positive visinin reactions occurred not only in the cones...

... was identified not only in the pineal gland, but also in extrapineal tissues and cells, e.g. the retina, Harderian gland, gut mucosa, cerebellum, airway epithelium, liver, kidney, adrenals, pancreas, thyroid gland and thymus. Also, melatonin has been found in some non-endocrine cells, e.g. mast cells, natural...

...T.C. Nag; S. Wadhwa The human retina, a derivative of the diencephalon, differentiates into its components in sequential patterns following a spatiotemporal order. The neuronal differentiation in the fovea and central retina begins earlier than that occurring elsewhere, completes by midgestation...

... in the central nervous system. The clinical relevance of developmental malformations and age-related diseases is briefly described. The possible effects of visual inputs on melatonin secretion and changes in this system during aging are summarized. Aging Development Melatonin Optic nerve Retina...

... of the retina, the iris and the cornea. Retinal morphogenesis encompasses four stages: (1) appearance of the ganglion cell layer, (2) formation of the outer plexiform layer separating the inner and outer nuclear layers, (3) formation of immature photoreceptor segments and (4) development of outer photoreceptor...
