A New Method for Generating Lost Cells Helps Blind Mice to See Again

MD, or age-related macular degeneration, is a wide range of ocular diseases that affect so many people, it’s downright described as nothing more than a process of aging.

How a Blind Person Can See Again

The study of MD has also proven itself to be useful for understanding how aging works as a whole. In an attempt to repair the damage to eyes and restore them back to a youthful and normal state, MD has quickly become one of the first places that scientists have looked into. In a new paper published online, researchers demonstrate an alternative to stem cells by creating photoreceptors from skin fibroblast cells. It’s a process that promises to be faster, more affordable, and unburdened by any legal or ethical restrictions.

Containing the generic code for every protein people need to repair or build cells, DNA can become damaged over time because of a stressful way of life. Just the way cracks and scratches on a CD prevent lasers from reading the information on it, damaged DNA becomes difficult, and in some cases, even impossible for our RNA to read the genetic information contained therein.

Ph. D. Sai Chavala says that the photoreceptors are the neurons in the eye that turn on visual circuity in response to light that enables us to have vision. The loss of photoreceptors can result in MD and other retinal diseases. They can cause a person to become irreversibly blind. In a study, however, cells called fibroblasts can be reprogrammed to reproduce cells that are similar to photoreceptors. They’re shown to restore the vision of mice.

Blind Mice

Sai Chavala and colleagues from the Center for Retina Innovation in Dallas, Texas, discovered a set of compounds that can drive embryonic fibroblast cells to convert themselves into rod-like retinal photoreceptors in both human and mice cells. Dr. Chavala says that stem cell-based strategies are extremely exciting but also adds that generating them can be time-consuming and cumbersome.

These conversions of fibroblasts to photoreceptors have also been done in humans. Dr. Chavala explained that he believes treatments and future research will spring from this discovery.

Y-Brush – A Smarter Toothbrush That Only Needs 10 Seconds

Y-Brush CloseupAbout 90 percent of case studies show that teeth brushing is done incorrectly. Health professionals make different recommendations from country to country. Teeth should be brushed for two to three minutes, twice a day. However, with the Y-Brush, it’s now possible to brush your teeth effectively in 10 seconds instead of two minutes.

Recently, the French company FasTeesh started selling the brush that cleans all your teeth in just 10 seconds. Fast forward to this year, the framework of the electronics fair CES 2021, the Y-Brush is back. It’s developed in close collaboration with dentists for over four years, and it’s able to brush teeth efficiently in only 10 seconds.

Unlike the regular, non-electrical toothbrush, Y-Brush’s patented technology cleans the teeth of the user in-depth, for adults and children alike. The electric toothbrush features a flexible gum shield lined with nylon bristles on one side, attached to a square power base.

The way that the electric toothbrush works is similar to the regular electric toothbrush. Instead of moving the little head of a toothbrush from tooth per tooth over two minutes, the special new device brushes all of the top teeth simultaneously for five seconds and then the bottom for the same amount of time. The toothbrush resembles a sports mouthguard that’s packed with nylon bristles. The motor that’s precisely installed in the handle of the brush conveys vibrations to a nylon bristle brush. In return, it moves to efficiently clean the gums, gum lines, and of course, the teeth all at once in the upper and lower part of the mouth.

The nylon bristles are fine enough to reach in between the teeth. They produce a deep clean and careful elimination of dental plaque. The brushes of the new Y-Brush are very flexible and therefore adaptable to jaws of all shapes and sizes, allowing for complete coverage of all of the teeth. It has three different vibration modes: soft (15 seconds), normal (10 seconds), and intense (5 seconds), and it comes with a charging stand. The battery is rechargeable, and a full charge lasts up to three months.
