Chemical and mechanical characterization of hyaluronic acid hydrogel cross-linked with polyethylen glycol and its use in dermatology.

Hydrogels based on hyaluronic acid are used to restore volume, hydration, and skin tone, as well as to correct scars, asymmetries or defects of the soft tissue. Hyaluronic acid is often chemically crosslinked with different crosslinking agents in order to improve its mechanical and biological properties. Here we focused on defining the chemical and mechanical characterization of a new hydrogel with specific characteristics: hyaluronic acid polyethylene glycol (PEG)-crosslinked with a high concentration of hyaluronic acid (28 mg/mL), manufactured by MatexLab Spa, via Carlo Urbani 2, ang Via Enrico Fermi, Brindisi, Italy.

A new medical imaging technique for diagnosing dermatologic diseases: A clue to treatment choices.

Recently, it has been shown that DNA could emit some waves which carry main information about its evolution. Using this idea, we design a new method to image the behavior of skin cells, especially melanocytes, and diagnose their damage. In this method, we make use of a circuit which is formed from DNAs within the damaged melanocytes, a graphene sheet, DNAs within the healthy cells, and a scope.

Immune profile of hyaluronic acid hydrogel polyethylene glycol crosslinked: An in vitro evaluation in human polymorphonuclear leukocytes.

Neauvia hydrogel (N-Gel) is a hyaluronic acid-based dermal filler, cross-linked with polyethylene glycol. This filler contains sodium hyaluronate at different concentrations, poly(ethylene glycol) diglycidyl ether cross-linked, glycine, and l-prolyne. Assessing any effects of N-Gel on immunity and inflammation is of crucial importance.
