Successfully developed artificial cornea in the United States An interdisciplinary research team composed of ophthalmology experts and chemical engineers from Stanford University has successfully developed an artificial cornea.
The material constituting the artificial cornea is duoptix, which is a two-layer network structure material formed by interlacing hydrogels. One layer consists of polyethylene glycol molecules, which have anti-surface protein accumulation and anti-inflammatory effects, and the other layer is a superabsorbent layer composed of polyacrylic acid molecules. The artificial cornea has a dish shape, is transparent in the center, and is densely covered with micropores. After being placed in the eye, the epithelial cells will infiltrate into the micropores and secrete collagen, thereby connecting the artificial cornea to the adjacent natural tissue, and then growing on the artificial cornea. A layer of epithelial cells.
Researchers are currently validating the biocompatibility of artificial corneas through animal experiments. Experiments of up to 8 weeks showed that the animals were well tolerated and the corneal transparency remained intact. Shanghai Medical Devices
Royal Jelly is also called Bee Milk. The fresh royal jelly is slightly ropy milk paste substance; it is the excretive mixture of nutrition gland and maxilla gland of the head of little worker bee. The worker bees use this to feed the 1-3 days` worker bee larva and drone larva, 1-5.5 days` queen bee larva and queen bee in the oviposition period. The royal jelly is the biologic product containing very complicated active elements which contains almost all the nutrition elements required by the growth of the human body.
