Abstract Delayed wound healing is a major complication of diabetes and the medical treatment of such wounds still remains a challenge. Among the modern wound dressings, film dressings are considered to be one of the major advances in wound management. In the current study, the feasibility of using a previously developed and optimized bioactive compounds-loaded chitosan film formulation as a functional wound dressing material for diabetic wounds was investigated. The antioxidant capacity, as well as the effect of the chitosan films on cell viability was assessed in vitro. Furthermore, the in vivo performance of the films was further evaluated, by using a streptozotocin-induced diabetic rat model. The chitosan film formulation provided a beneficial moist wound environment, reducing the risk of dehydration and favouring the closure of the wounds. Also, it exhibited good antioxidant activity, as well as a proliferative effect and adequate biocompatibility. The in vivo evaluation of the bioactive compounds-loaded chitosan film formulation confirmed that the biofilm stimulated wound contraction and accelerated the wound healing process. The results strongly support that the above mentioned chitosan film seems to be a promising formulation, as well as a potential and novel biomaterial used for wound healing applications.

Abstract In the present study, a Quality by Design (QbD) approach was applied in order to develop and optimize a chitosan film formulation loaded with bioactive compounds, intended for further use as an aid in the acceleration of wound healing. Chitosan was chosen as film forming polymer, polyethylene glycol was used as plasticizer, while polyvinyl alcohol was added to improve the bioadhesive properties of the films. Risk assessment strategy was applied to identify the critical formulation varia...

Abstract Polyphenols are reported to provide treatment for specific pathological situations. Acridocarpus orientalis and Moringa peregrina are reported to contain highly antioxidant polyphenols, which prompted us to investigate the total polyphenol contents in these natural resources. The dried plant materials were extracted with methanol and then submitted for NIR spectroscopic analysis in the wavelength ranges 700–2500 nm, followed by PLS regression. The external cross-validation was done by t...

Abstract Arnica montana is a popular traditional remedy widely used in complementary and alternative medicine, in part for its wound-healing properties. The authors recently showed that this plant extract and several of its homeopathic dilutions are able to modify the expression of a series of genes involved in inflammation and connective tissue regeneration. Their studies opened a debate, including criticisms to the “errors” in the methods used and the “confounders and biases”. Here the authors...

Plastic, usually derived from non-renewable sources, is among the most used materials in food packaging. Despite its barrier properties, plastic packaging has a recycling rate below the ideal and its accumulation in the environment leads to environmental issues. One of the solutions approached to minimize this impact is the development of food packaging materials made from polymers from renewable sources that, in addition to being biodegradable, can also be edible. Different biopolymers from agr...

Abstract Wound dressings based on natural polymers are of considerable interest in the pharmaceutical industry owing to their improved performance in the human body when compared to synthetic polymers. Alginate, a polysaccharide from brown algae, is commonly studied as a wound dressing owing to its biocompatibility and biodegradability. To improve its therapeutic features and thereby increase wound healing, papain (a proteolytic enzyme from Carica papaya latex) was proposed to be incorporated. P...

Marine-derived chitosan has been widely examined for its use in developing biomedical materials. Not only is it non-toxic, biocompatible, and degradable, it has also shown unique antimicrobial properties. The antimicrobial properties of chitosan are restricted by neutral and physiological conditions because it is insoluble in water and its pKa values is 6.5. One solution to this problem is to graft chemically modified groups onto the backbone of chitosan. The aim of this paper is to review the m...
