Sentences with phrase «form rod cells»

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).

Not exact matches

In people with sickle cell anemia, molecules of sickle hemoglobin clump together and form long rods that cause red blood cells to become rigid and take on a sickle shape.

A wire - wound metal rod is then pulled across the cell, spreading out the solution and forming a coating made of closely packed nanoresonators.

Some of these clusters form at the cell poles, the rounded ends of rod - shaped bacteria like Escherichia coli.

Cells normally have two centrioles that work together as a unit to anchor and organize microtubules, the molecular rods that form the cell's backbone.

Rods and cones, the major light receptor cells in the mammalian eye, are densely packed across the retina where they convert light into the image - forming signals that allow the brain to create vision.

The inset image shows a cross-section of a sickle cell with abnormal (sickle) hemoglobin forming abnormal stiff rods.

All forms of CRD are characterized by the initial loss of cones, the cells in the retina that are responsible for vision in bright light / daylight, followed by the degeneration of rods, the retinal cells that operate during night vision.

The disease itself is painless but affected dogs should be regularly monitored by an ophthalmologist to treat possible secondary effects of PRA (the most widespread form of PRA across dog breeds) IG - PRA1 first presents as a loss of vision in dim light conditions due to degeneration of rod cells in the retina.

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.

Rod Cone Dysplasia Type 1b (rcd1b), previously named CRD1, is an early - onset form of retinal degeneration that is characterized by the loss of rods and cones, the cells in the retina that are responsible for vision.

Progressive retinal atrophy (PRA) and cone - rod dystrophy (CRD) are collective terms for two broad forms of progressive, bilateral degenerative diseases that affect the retinal photoreceptor cells.

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.
