  1. 1. Intestinal absorption of drugs The impact of regional permeability, nanoparticles, and absorption-modifying excipients

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Carl Roos; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Permeability; intestinal absorption; regional permeability; nanoparticles; nanosuspensions; absorption-modifying excipients; AMEs; Biofarmaci; Biopharmaceutics;

    Abstract : For successful delivery of orally given drug products, the drug compounds must have adequate solubility and permeability in the human gastrointestinal tract. The permeability of a compound is determined by its size and lipophilicity, and is usually evaluated in various pre-clinical models, including rat models. READ MORE

  2. 2. Function of granulocytes after burns and trauma, associations with pulmonary vascular permeability, acute respiratory distress syndrome, and immunomodulation

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Joakim Johansson; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ARDS; azurocidin; burn; CAP-37; critical care; granulocyte; HBP; histamine; intensive care; leucocyte; leukocyte; mediator; methylhistamine; MOF; oedema; neutrophil; permeability; PMN; trauma; vascular permeability;

    Abstract : Background: Our innate immunesystem protects us from infections but, since its methods is not all specific for microorganisms, may also induce collateral damage.Severe physical injury often proved deadly throughout evolution. Such injuries may induce massive collateral damage. READ MORE

    Abstract : Popular Abstract in Swedish I magtarmkanalen upptas ständigt nyttiga näringsämnen, men samtidigt avvisas skadliga bakterier, gifter och allergiframkallande ämnen. I avhandling beskrivs hur tarmens normala barriärfunktion hos råtta och gris kan förändras på konstgjord väg. READ MORE

  4. 4. Shaping Macroporous Ceramics templated synthesis, X-ray tomography and permeability

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Linnéa Andersson; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alumina; ceramic; CO2 capture; colloidal processing; expandable microspheres; gel casting; layer-by-layer; macroporosity; near-net shape; non-destructive evaluation; permeability; porosity; sacrificial templating; X-ray computed tomography; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Materials Chemistry; materialkemi;

    Abstract : Macroporous ceramic materials have found widespread technological application ranging from particulate filters in diesel engines, tissue engineering scaffolds, and as support materials in carbon capture processes. This thesis demonstrates how the pore space of macroporous alumina can be manipulated, analysed in three-dimensions (3D) using visualisation techniques, and functionalised with a CO2-adsorbing material.
