2. 1. In vitro and in vivo studies of tissue engineering in reconstructive plastic surgery

   Author : Fredrik R.M. Huss; Gunnar Kratz; Elof Eriksson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue engineering; plastic surgery; guided tissue regeneration; Plastic surgery; Plastikkirurgi; Plastikkirurgi;

   Abstract : To correct, improve, and maintain tissues, and their functions, are common denominators in tissue engineering and reconstructive plastic surgery. This can be achieved by using autolo-gous tissues as in flaps or transplants. However, often autologous tissue is not useable. READ MORE

4. 2. Fruit wastes to biomaterials : Development of biofilms and 3D objects in a circular economy system

   Author : Veronika Bátori; Kristiina Oksman; Högskolan i Borås; []
   Keywords : apple pomace; biodegradable; bioplastics; circular economy; orange waste; resource recovery; Resource Recovery; Resursåtervinning;

   Abstract : To address the current plastic pollution problem, the replacement of conventional plastics with bioplastics can be considered. Although the land use of crop cultivation for bioplastics is still negligible, there is an increasing interest in the utilisation of lignocellulosic waste products for the production of bioplastics.

   Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

6. 4. In vitro and in vivo studies on biodegradable matrices for autotransplantation

   Author : Carl-Johan Gustafson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : In vitro; in vivo; dermis; matrix; autotransplantation; culture; keratinocytes; urothelium; tissue engineering; PUUR; macroporous spheres ; guided tissue regeneration;

   Abstract : Tissue engineering (TE), one of the most rapidly growing fields of life science, is an interdisciplinary area in which technical, biological and medical expertise co-fertilize on another with the ultimate aim of restoring, maintaining or improving tissues and/or organs. This purpose links TE closely to research concerning reconstructive plastic surgery. READ MORE

7. 5. Exploring bio-based and biodegradable polymers: free-radical polymerization, hydrolysis and applications

   Author : Maryam Mousa; Eva Malmström; Magnus Jonsson; Anna Larsson Kron; Seema Agarwal; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bio-based polymers; biodegradation; branched polyesters; thermally expandable microspheres; copolymerization; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Increasing concerns regarding the depletion of fossil-based resources and theaccumulation of plastic waste in the environment have resulted in extensiveresearch aimed at finding more sustainable alternatives to today’s plastics.In this work, bio-based and biodegradable polymers have been synthesizedusing free-radical polymerization in homogeneous and heterogeneoussystems.
