“…21 The HA surface-treated materials have also been demonstrated to have good blood compatibility and can induce the release of growth factors from platelet-rich plasma to effectively reduce platelet adhesion and thrombosis. 22,23 Herein, alkali treatment combined with the subsequent layer-by-layer assembly was used in the present study to form a multifunctional coating on the surface of Mg aimed at enhancing corrosion resistant, cytocompatibility to the endothelial cells as well as blood anticoagulant activity and endeavoured to provide a basis for clinical applications of biomedical Mg-based alloys. Mg/OH is negatively charged after the generation of -OH on the surface of Mg matrix by alkali heat treatment.…”

Magnesium alloys are promising cardiovascular stent materials due to the favourable physical properties and complete biodegradability in vivo. However, the rapid degradation, poor cytocompatibility and tendency of thrombogenesis hinder practical clinical applications. In order to solve these problems, a facile and highly efficient strategy of alkali treatment combined with subsequent layer-by-layer assembly was used to fabricate a multifunctional coating. A bottom layer hydroxyl (–OH) with negative charge after alkali treatment first formed a solid bond with magnesium matrix to provide a rough outer surface for the further immobilization of functional biomolecules. Afterwards, polydopamine and hyaluronic acid were successively immobilized on alkali-treated magnesium surface via strong electrostatic adsorption and covalent bonding between carboxyl group of hyaluronic acid and amine or hydroxyl of polydopamine to form magnesium/OH/polydopamine/hyaluronic acid. Hydroxyl significantly improves the corrosion resistance while polydopamine and hyaluronic acid layers act as a further barrier to provide better anticorrosion. A balance between biocompatibility and antithrombogenicity has been achieved by adjusting the content of hyaluronic acid on polydopamine surface. The multifunctional magnesium/OH/polydopamine/hyaluronic acid coating with lower hyaluronic acid concentrations expose more active sites of polydopamine molecules to promote endothelial cell proliferation while retaining the intrinsic antithrombogenic function of hyaluronic acid to offer a potential application for vascular stents.

“…In previous studies, animal models of fibrotic disease in laryngology were induced using mechanical or thermal injury, leading to mucosal injuries that were inconsistent in their extent and/or depth (Cho, Seo, Park, Joung, & Han, 2017; Choi et al, 2018). Therefore, in the present study, we established a reliable rabbit model using laser irradiation delivered via a cylindrical diffuser in accordance with our previous work (Lee et al, 2019).…”

Phlorotannins ameliorate extracellular matrix production in human vocal fold fibroblasts and prevent vocal fold fibrosis via aerosol inhalation in a laser‐induced fibrosis model

Vocal fold fibrosis is an abnormal condition characterized by unfavorable changes in the organization of the extracellular matrix in vocal fold lamina propria. To prevent and treat vocal fold fibrosis, a number of synthetic drugs, such as mitomycin C and the glucocorticoid family, are used after surgery, but these are known to have some side effects. Therefore, using both in vitro and in vivo studies, this study investigated whether phlorotannins extracted from Ecklonia cava have the potential to prevent vocal fold fibrosis with minimal side effects. The results show that phlorotannins suppressed both the expression of the fibrotic phenotypic marker and cell migration by inhibiting the activation of the mitogen‐activated protein kinase (MAPK) and Smad2/3 signaling pathways in human vocal fold fibroblasts stimulated by transforming growth factor‐β. Additionally, phlorotannins exhibited antifibrotic efficacy without an excessive inflammatory response in a laser‐induced fibrosis rabbit model when delivered as an aerosol via inhalation. Based on these results, phlorotannins should be considered a promising candidate for use in the prevention of vocal fold fibrosis.

“…Many interesting methods based on catechol have been developed to modify almost all types of surfaces, and it is a universal method . Most of the reported works are coated with DA only, followed by another reaction, such as alkali treatment . Covalently grafting catechol groups to the existing polymer will greatly enhance the design and application area of surface modification …”

“…The water can potentially weaken the interactions between polymers and surfaces. Fortunately, catechol‐functionalized polymers can enhance the surface adhesion and enable a mechanically robust coating tightly on the surface of the intrinsic hydrophobic polymers . This is of particular interest for practical applications.…”

Super‐hydrophilic coatings are useful in many applications such as agricultural greenhouses. However, the direct modification of super‐hydrophilic coatings on intrinsic hydrophobic surfaces is still a challenge, particularly without any pretreatment. Here, highly transparent super‐hydrophilic and waterproof coatings on intrinsic hydrophobic surfaces were prepared via layer‐by‐layer (LbL) assembly catechol‐grafted polymer‐branched poly(ethylenimine) (bPEI)‐3‐(3,4‐dihydroxyphenyl)propionic acid (denoted as C) and poly(acrylic acid) (PAA)‐dopamine (denoted as D) inspired by the mussel. The catechol‐functionalized polymer facilitates a mechanically robust coating that is tightly attached to the surface of the intrinsic hydrophobic polymers. This gives the coating excellent antifogging ability with a lowest contact angle of 0°. These coatings also demonstrated excellent stability after cross‐linking with Fe3+ or alkali species. The super‐hydrophilic and waterproof coatings on intrinsic hydrophobic surfaces can also be prepared by the spray method. The super hydrophilic coating exhibits favorable antifogging ability, making it potentially useful in numerous applications. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48013.
