A variety of dressings has been used for covering the split thickness skin graft donor areas. Some of these are alginates, collagen sheets, films and the most commonly used impregnat‐ ed tulle gras dressing. The chief goal of management of donor area is to achieve early epi‐ thelisation without infection. Minimum pain, easy availability and low cost of dressing are other desirable criteria. A c...

John Timmons is Editor of Wounds UK and Clinical Nurse Specialist, Department of Tissue Viability, Aberdeen Royal Infirmary Exudate management is a challenge for the healthcare team as well as for the patient and despite a number of products being available, many patients still feel that exudate management is a significant problem, particularly for cavity wounds. Alginate dressings have been av...

Radioactive isotopes of strontium, mainly Sr, may considerably contribute to the total activity of long-lived fission products released into the environment in nuclear accidents. Consequently, the ingestion of strontium radionuclides with contaminated foodstuffs may result in a significant internal radiation exposure of members of the public. The committed radiation dose dependents significantl...

Aqueous chitosan possesses attractive interaction capacities with various molecular groups that can be involved in hydrogen bonds and electrostatic and hydrophobic interactions. In the present paper, we report on the direct determination of chitosan–mucin molecular pair interactions at various solvent conditions as compared to alginate–mucin interactions. Two chitosans of high molecular weight ...

The use of a number of species of marine brown algae in the implementation of bioremediation strategies for toxic heavy metals is being considered and evaluated. The biosorption capacity of these algae for heavy metals resides mainly in a group of linear polysaccharides known as alginates that occur as a gel in the algal thallus. The potential for selective metal binding by the biomass of two s...

Despite the success of alginate scaffolds and mesenchymal stem cells (MSCs) therapy in cardiac failure treatment, the impact of the physicochemical environment provided by alginate matrices on cell behavior has never been investigated. The purpose of this work was double: to determine the alginate composition influence on (1) encapsulated rat MSC viability, paracrine activity, and phenotype in...

Alginates isolated from Sargassum vulgare, present a strong antitumor activity, associated with kidney reversible damage, as analysed by histopathology of treated animals. In the present study, the renal alteration mechanisms of S. vulgare alginates were investigated using the isolated perfused rat kidney and the isolated perfused rat mesenteric blood vessel methods. The results showed that the...

Alginates have been shown not only to be beneficial in their relief of symptomatic post-prandial gastroesophageal reflux, but there is also evidence that they may inhibit reflux, including bile acids and pepsin, and in turn attenuate and even prevent the activation and up-regulation of molecules associated with the development of metaplasia and cancer of the esophagus. Here we present the case ...
