Abstract
In the cosmetic sector, natural and sustainable products with a high compatibility with skin, thus conjugating wellness with a green-oriented consumerism, are required by the market. Poly(hydroxyalkanoate) (PHA)/starch blends represent a promising alternative to prepare flexible films as support for innovative beauty masks, wearable after wetting and releasing starch and other selected molecules. Nevertheless, preparing these films by extrusion is difficult due to the high viscosity of the polymer melt at the temperature suitable for processing starch. The preparation of blends including poly(butylene succinate-co-adipate) (PBSA) or poly(butylene adipate-co-terephthalate) (PBAT) was investigated as a strategy to better modulate melt viscosity in view of a possible industrial production of beauty mask films. The release properties of films in water, connected to their morphology, was also investigated by extraction trials, infrared spectroscopy and stereo and electron microscopy. Then, the biocompatibility with cells was assessed by considering both mesenchymal stromal cells and keratinocytes. All the results were discussed considering the morphology of the films. This study evidenced the possibility of modulating thanks to the selection of composition and the materials processing of the properties necessary for producing films with tailored properties and processability for beauty masks.

Han G, Nguyen LN, Macherla C, Chi Y, Friedman JM, Nosanchuk JD, Martinez LR. Nitric oxide-releasing nanoparticles accelerate wound healing by promoting fibroblast migration and collagen deposition. THE AMERICAN JOURNAL OF PATHOLOGY 2012; 180:1465-73. [PMID: 22306734 DOI: 10.1016/j.ajpath.2011.12.013] [Citation(s) in RCA: 120] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 03/18/2011] [Revised: 11/28/2011] [Accepted: 12/08/2011] [Indexed: 01/13/2023]
Abstract
Wound healing is a complex process that involves coordinated interactions between diverse immunological and biological systems. Long-term wounds remain a challenging clinical problem, affecting approximately 6 million patients per year, with a high economic impact. To exacerbate the problem, these wounds render the individual susceptible to life-threatening microbial infections. Because current therapeutic strategies have proved suboptimal, it is imperative to focus on new therapeutic approaches and the development of technologies for both short- and long-term wound management. In recent years, nitric oxide (NO) has emerged as a critical molecule in wound healing, with NO levels increasing rapidly after skin damage and gradually decreasing as the healing process progresses. In this study, we examined the effects of a novel NO-releasing nanoparticle technology on wound healing in mice. The results show that the NO nanoparticles (NO-np) significantly accelerated wound healing. NO-np modified leukocyte migration and increased tumor growth factor-β production in the wound area, which subsequently promoted angiogenesis to enhance the healing process. By using human dermal fibroblasts, we demonstrate that NO-np increased fibroblast migration and collagen deposition in wounded tissue. Together, these data show that NO-releasing nanoparticles have the ability to modulate and accelerate wound healing in a pleiotropic manner.
