  2. 1. Polymer Gels as Pharmaceutical Dosage Forms : Rheological Performance and Physicochemical Interactions at the Gel-Mucus Interface for Formulations Intended for Mucosal Drug Delivery

    Author : Helene Hägerström; Katarina Edsman; Arne Brodin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; gel; rheology; mucoadhesion; mucosal drug delivery; in situ gel; gellan gum; Carbopol; tensile strength; nasal mucosa; intranasal administration; dielectric spectroscopy; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : Drug delivery to the nasal and ocular mucosa faces several obstacles. One of these is from the effective clearance mechanisms present in the nose and eye. Polymer gels with suitable rheological properties can facilitate the absorption of poorly absorbed drugs by increasing the contact time of the drug with the mucosa. READ MORE

  4. 2. A scattering study of concentrated lens protein solutions and mixtures - Towards understanding the molecular origin of presbyopia

    Author : Saskia Bucciarelli; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; scattering; eye lens; presbyopia; dynamical arrest; crowding; proteins; dynamics; crystallins;

    Abstract : Healthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. READ MORE

  5. 3. Sol-Gel Glasses Doped with Pt-Acetylides and Gold Nanoparticles for Enhanced Optical Power Limiting

    Author : Hampus Lundén; Mikael Lindgren; Cesar Lopes; Staffan Tjörnhammar; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : High power laser pulses can be a threat to sensors, including the human eye. Traditionally this threat has been alleviated by colour filters that blocks radiation in chosen wavelength ranges. READ MORE

  6. 4. Modulating the structure-function relationship of mucin materials

    Author : Kun Jiang; Thomas Crouzier; Qi Zhou; Mark Tibbitt; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioteknologi; Biotechnology;

    Abstract : Mucus covers the epithelium surfaces playing a key role in the barrier, hydration, lubrication and bioactivity functions for the human body, and mucins are the fundamental components of mucus which provide such functions. However, many details in how these functions are related to the many structural features of mucins are still unknown. READ MORE

  7. 5. Nonlinear materials for optical power limiting : characterization and modelling

    Author : Hampus Lundén; Mikael Lindgren; Cesar Lopes; Bernd Eberle; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High power laser pulses can be a threat to optical sensors, including the human eye. Traditionally this threat has been alleviated by colour filters that block radiation in chosen wavelength ranges. READ MORE
