ageless medicine

Kupang to drug use of youth.
With the help of Kupang sea, scientists in South Korea has developed a gel that can be injected which can be useful for mnemenuhi wrinkles. Hyaluronic acid hydrogels (HA) is often used as biocompatible materials for drug delivery and tissue engineering, but they have a weak mechanical strength and to degradation in vivo is faster because they absorb water and to enzymatic degradation.

By adding an acid amino acid found in Kupang, more stable and adhesive hydrogels made by Tae Gwan Park and his colleagues from the Korea Advanced Institute of Science and Technology, Daejeon.

A common amino acid in Kupang to make the gel attached to the network.
Park uses amino acids, 3,4-dihydroxyphenylalanine, which are common in Kupang adhesive layer which makes it easier to stick firmly to a variety of organic and inorganic surfaces. Amino acid makes the gel stick to the network, certainly Park, which makes it useful for tissue engineering, drug delivery and even to fill wrinkles. Hydrogels fluid injected into the body where as soon as possible turned to the gel during temperature changes. 'Formation of gel in the body can act as a suspension for supporting the release of the drug, or the network formation can act as the glue network, "said Park.

Zhiyuan Zhong from Soochow University, Suzhou, China, who examined hydrogels that can be injected and biodegradable polymer, was impressed with the findings Park. 'These hydrogels have elegantly combined the injection level, the stability in vivo, the ability biodegradability, good mechanical properties, the sensitivity of network properties panasdan a good adhesive.' He added that 'something that can be injected, but a very complex hydrogels are the basis for materials were well received and easy to prepare. "

Park said his team now berencan to use adhesive hydrogels that can be injected to clinical applications with drug therapy in the form of capsules or pressed cells - the cells within them and also worked on testing in vivo.
