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

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

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

    Sammanfattning : 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. LÄS MER

  3. 2. Effects of pharmaceutical excipients on the chemical stability of therapeutic proteins in a parenteral formulation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Emmanuel Gulangayan Deniola; [2022]

    Sammanfattning : Rheumatoid arthritis (RA) is a chronic, inflammatory, autoimmune disease that although systemic, mainly affects the synovium of the joints. Currently, remission is the goal of RA treatment. Research efforts are however targeted towards finding a cure. Radix Gentiana macrophylla Pall. LÄS MER

  5. 4. Minimization of chemical's release from a large-scale pharmaceutical industry : By optimization of the crystallization process

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Cecilia Rahn; [2021]
    Nyckelord :Minimization of release; pharmaceutical industry; crystallization; optimization; Minimering av utsläpp; läkemedelsindustri; kristallisation; optimering;

    Sammanfattning : The presence of active pharmaceutical ingredients (APIs) and other chemicals in wastewater has caused concerns in recent years due to its potential risk to the environment and society. Thus, the aim of the study is to investigate ways to minimize the release of chemicals from a large-scale pharmaceutical industry to an industrial wastewater treatment plant. LÄS MER

  7. 5. Method development for quality control of the primary explosive, Potassium 4,6-Dinitrobenzofuroxan (KDNBF)

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Edvin Elmroth; [2020]
    Nyckelord :“Green” explosives; KDNBF; GC-FID; HPLC-UV VIS; Potentiometric titration;

    Sammanfattning : “Green” explosives are an important sub-family of explosives due to the banning of explosives based on heavy metals, such as lead azide and lead styphnate, according to the REACH list. A substitute to lead azide is potassium 4,6-dinitrobenzofuroxane (KDNBF) which is an alternative “green” explosive. LÄS MER
