  1. 1. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
    Keywords : hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

    Abstract : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. READ MORE

    University essay from

    Author : Tilda Eriksson; Lisa Quakkelaar; Alexander Parkstam; Alina Karlsson; Mansourah Askari; Shukri Said Ahmed; [2022]
    Keywords : Hyaluronan; Hyaluronic Acid; HA; 1; 4-Butanediol diglycidyl ether; BDDE; polynucleotides; mannitol; biomedical applications; dermatological fillers; fillers; Hyaluronan; Hyaluronsyra; HA; 1; 4-butandiol diglycidyleter; BDDE; polynukleotider; mannitol; biomedicinska applikationer; dermatologiska fyllmedel; fyllmedel;

    Abstract : Hyaluronan (HA) is a substance that is commonly used in biomedical applications in the form of hydrogels. One of these biomedical applications is dermatological fillers where HA is cross-linked with 1,4-Butanediol diglycidyl ether (BDDE) to reduce its rapid turnover within tissue. The filler gives a volumetric effect that can fill out wrinkles. READ MORE

  4. 3. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels

    University essay from SLU/Dept. of Clinical Sciences

    Author : Anna Kotila-Ioannou; [2022]
    Keywords : Camel Semen; Dromedary camel; Sperm-Hyaluronan Binding Assay; sperm quality analysis;

    Abstract : The objective of this study was to assess the potential of Hyaluronan Binding Assay (HBA) to predict freezability and fertilization capacity of dromedary camel spermatozoa, and to determine if conventional sperm quality parameters and precursor of A-Kinase Anchoring Protein 4 (proAKAP4) values correlate with HBA results. Two semen samples were collected from each of six male camels. READ MORE

  5. 4. Fibers and Textiles Produced from Chitin and Chitosan : A Literature Study For Different Production Methods

    Keywords : chitin; chitosan; fibers; nanofibers; textiles; wound dressing; sutures; spinning;

    Abstract : Ökningen av världspopulationen har orsakat en ökad avfallsgenerering. Avfallet kan innehålla betydelsefulla ämnen, vilka kan användas som råvaror i många olika material och för olika ändamål. READ MORE

  6. 5. Evolution of the synovial joints in Osteichthyes : Cells displaying functional similarities to synoviocytes in zebrafish Danio rerio

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Sara Gillnäs; [2019]
    Keywords : synovial joints; development; zebrafish; synoviocytes;

    Abstract : Synovial joints enable frictionless movement between the adjacent bones. Lubricating fluid enclosed within the joint reduce the pressure to allow free movement. READ MORE
