Sentences with phrase «rod cells from»

When the researchers examined the epigenetics of purified rod cells from mice, they saw that these aspects became repressed by histone and DNA methylations later in development, ten days after the mice were born.

One of these two photons is detected by a photodiode and used to trigger an acousto - optical modulator, causing it to divert the second photon to a tapered optical fiber directed at a pipette containing a rod cell from a frog's eye (see image).

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.»

These cells ferry optical signals from the rods and cones to the brain, so the mice regained some ability to see light.

Last year, Robin Ali of University College London and colleagues demonstrated that immature retina cells from newborn mice could form rod cells — a type of light - gathering cell — that wire into the retinas of night - blind adult mice (SN: 5/19/12, p. 13).

As it turns out, the missing link was a previously unknown type of light - sensitive cell in the human eye, distinct from the familiar rods and cones that are responsible, respectively, for night and color vision.

The vertebrates» photoreceptor cells, typified by rods and cones, are quite distinctive from the invertebrates».

While the biomechanical controls that determine the dimensions of other flagellar components have already been determined, the control of the length of the rod, a rigid shaft that transfers torque from the flagellar motor in the interior of the cell to the external propeller filament, were unknown.

They receive and process signals from the retina's light - detecting cells, the rods and the cones, and transmit them to another set of cells that, in turn, transfer the information to the brain.

The trick was to use a new synthetic switch to confer light sensitivity on the retinal ganglion cells in these mice, which normally respond to signals from the rods and cones upstream of them.

Experiments on cells from frogs have shown that sensitive light - detecting cells in vertebrate eyes, called rod cells, do fire in response to single photons.

Racing against the clock, since rod cells lose their viability after one to two hours, the researchers measured ten rods cells taken from ten different frogs.

«We've provided evidence that by acquiring the regulatory elements for NRL to shift short - wavelength cones into rods, early mammals changed one type of cell from capturing UV light — which isn't necessary at night — to something that is just extremely sensitive to light.»

They found an average quantum efficiency of approximately 30 per cent — very close to that of human rod cells estimated from behavioral experiments.

Horizontal cells process visual information by integrating and regulating input from rod and cone photoreceptors, which allow eyes to adjust to see well in both bright and dim light conditions.

The layering within these columns was indistinguishable from the adjacent, control retina and contained cells with the appropriate morphology for their nuclear layer (rods and cones in the ONL, bipolar, amacrine, horizontal, and Müller glia in the INL, and RGCs in the GCL).

Z - series movie of the rod photoreceptor derived from EFTF - expressing pluripotent cells in Figure 5E.

Behind the photoreceptors is another layer of cells called retinal pigment epithelium (RPE), which support the rods and cones by delivering nutrients from the bloodstream and removing waste that the rods and cones generate.

However, the morphology of the host inner retinal cells was well - preserved in the area of donor cell migration, as evident from the PKCα antibody staining, which labeled normal - appearing rod bipolar cell dendrites (upward arrows in Figure 6B).

We want to help guide people when it comes to credit decisions — from applying for a new cell phone to getting their first mortgage — and be there for each step big and small,» said Rod Griffin, director of public education at Experian.

This is different from typical progressive retinal degeneration (PRA), which involves both the rod and cone cells of the retina causing night blindness and worsening day vision.

Presenting large - scale installations that resemble elements of nature under a microscope and cell - like forms or organisms from the depths of the ocean, Donovan's body of work derives from recognisable everyday items, such as Scotch Tape, drinking straws, paper - plates, needles, plastic rods and toothpicks.
