  2. 6. Formulations, Release and Skin Penetration of Topical Anesthetics

    Author : Katayoun Welin-Berger; Brian W. Barry; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Abstract : This thesis describes certain critical aspects of the development of semisolid topical anesthetic formulations requiring a fast onset of action. Furthermore, local anesthetics were investigated regarding their phase interaction with membrane lipids. READ MORE

  4. 7. The role of the mitochondrial membrane system in apoptosis : the influence of oxidative stress on membranes and their interactions with apoptosis-regulating Bcl-2 proteins

    Author : Martin Lidman; Gerhard Gröbner; Magnus Wolf-Watz; Philip Williamson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bax; Bc-2; apoptosis; mitochondria; membranes; oxidized lipids; NMR; calorimetry; circular dichroism; biokemi; Biochemistry; fysikalisk kemi; Physical Chemistry;

    Abstract : Apoptosis is a crucial process in multicellular organisms in sculpting them, especially during embryogenesis. In addition, apoptosis is responsible for the clearance of harmful or damaged cells which can otherwise be detrimental to the organism. READ MORE

  5. 8. Dynorphin A – Interactions with receptors and the membrane bilayer

    Author : Johannes Björnerås; Lena Mäler; Astrid Gräslund; Göran Widmalm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik; Biochemistry; biokemi;

    Abstract : The work presented in this thesis concerns the dynorphin neuropeptides, and dynorphin A (DynA) in particular. DynA belongs to the wider class of typical opioid peptides that, together with the opioid receptors, a four-membered family of GPCR membrane proteins, form the opioid system. READ MORE

  6. 9. Interfacing spectrophotometry to process liquors applications to kraft pulping

    Author : Xiaotian Yang; KTH; []
    Keywords : Kraft cooking; On-line; Sulfide; Lignin; Polysulfide excess sulfur; Anthraquinone-2-sulfonate; Anthraquinone; Nafion membrane; UV-Vis; ATR-probe; Spectrophotometric;

    Abstract : This thesis summarizes the outcome of work performed withthe objective to contribute to the knowledge and development ofthe kraft cooking process using spectrophotometricinterfaces.In kraft cooking, it is desirable to maximize the removal oflignin in the cook without loss of pulp strength.

  7. 10. Bacterial interaction with the fibrinolytic system and extracellular matrix

    Author : Thomas Herrman Eberhard; Karolinska Institutet; Karolinska Institutet; []
    Keywords : plasminogen; extracellular matrix; basement membrane; virulence factors; fibronectin; vitronectin; collagen; Haemophilus influenzae Neisseria meningitidis Streptococcus pneumoniae;

    Abstract : Bacterial infection of host organisms is a state of complex interaction between the parasite and the host. Two critical steps in the infectious process are: Adhesion to the epithelial surfaces and penetration of tissue barriers to gain entrance to tissues and into the circulation. These two steps have been the subjects of this thesis. READ MORE
