4. 2. Nanocellulose based 3D printed hydrogel scaffolds for cartilage and bone regeneration : Tuning of composition, pore structure and functions

   Author : Sahar Sultan; Aji P. Mathew; Lennart Bergström; Gustav Nyström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose materials; 3D printing; gradient biphasic hydrogel scaffolds; metal-organic frameworks; hydroxyapatite; cartilage and bone regeneration; osteochondral scaffolds; materialkemi; Materials Chemistry;

   Abstract : Biobased-materials with customized scaffolds have played a prominent role in the success of tissue engineering (TE). Cellulose nanomaterials (CNM) isolated from the abundant biopolymer, cellulose, is explored in this thesis for TE engineering due to its versatile properties such as biocompatibility, high specific strength, surface functionality and water retention capacity.

7. 5. A web- and mobile phone-based obesity prevention intervention in 4-year-olds : a population-based randomized controlled trial

   Author : Christine Delisle Nyström; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Childhood overweight and obesity has increased significantly over the past two decades. Many well-conducted obesity prevention trials have been conducted in pre-school aged children but the majority have not been able to show changes in obesity related markers. READ MORE
