They tested it in a rat model of ADRP and found that after 2 to 3 months, eyes that had been injected with the virus - ribozyme combo contained 30 to 40 % more rod cells than eyes that received a dummy injection.

Heat and light, being modes of motion, «phosphorescence» and «incandescence» are phenomena to which consciousness has been likened by the production - theory: «As one sees a metallic rod, placed in a glowing furnace, gradually heat itself, and — as the undulations of the caloric grow more and more frequent — pass successively from the shades of bright red to dark red (sic), to white, and develope, as its temperature rises, heat and light, — so the living sensitive cells, in presence of the incitations that solicit them, exalt themselves progressively as to their most interior sensibility, enter into a phase of erethism, and at a certain number of vibrations, set free (dégagent) pain as a physiological expression of this same sensibility superheated to a red - white.»
Rod - shaped cells are far more sensitive to dim light, but they do not pick up color and can not detect red light.

The research, published this week in the Proceedings of the National Academy of Sciences USA (PNAS), indicates that rod - shaped particles (150 nanometers in diameter by 450 nanometers long) penetrated human cells about four times faster and traveled farther into the cells than particles with more balanced dimensions (such as 200 nanometers by 200 nanometers).
On the other hand, less mature cells have more self - renewal properties and possibly more potential to integrate and repair the eye's rods and cones.
The lack of color sense is balanced by the dog having many more rods, light - sensitive cells on the retina, than people do.
These rod cells are more sensitive to low light, meaning they can sense motion in the dark.
However unlike other forms of Day Blindness observed in other breeds, the DB / RD mutation causes a more complete retinal degeneration in the Standard Poodle and affected dogs eventually lose both cone and rod cell function resulting in vision loss under all lighting conditions.
