  1. 1. New insights in contact allergy and drug delivery. A study of formulation effects and hapten targets in skin using two-photon fluorescence microscopy

    Author : Carl Simonsson; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; contact allergy; cubic phases; cutaneous absorption; bromobimane; isothiocyanate; lipid vesicles; nano; pilosebaceous unit; two-photon microscopy;

    Abstract : The skin is a remarkable barrier, protecting us from invasion of e.g. harmful microorganisms and UV-radiation. However, the skin is not adopted to resist repeated exposure to the multitude of xenobiotics introduced into modern society. READ MORE

  2. 2. Development of Nonlinear Microscopy for Studies of Metabolism and Tissue Engineering

    Author : Madeleine Åkeson; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; imaging; bacterial cellulose; nonlinear microscopy; Saccharomyces cerevisiae; yeast; C. elegans; Microscopy; lipid storage;

    Abstract : Nonlinear microscopy techniques provide abilities for noninvasive and selective imaging of structural and chemical properties of biological systems. These techniques include coherent anti-Stokes Raman scattering (CARS) microscopy with the ability to selectively image molecular vibrations, second harmonic generation (SHG) microscopy which selectively images fiber structures, and third harmonic generation (THG) microscopy which is sensitive to interfaces between materials with different optical properties.

  3. 3. Non-linear Optical Microscopy and Spectroscopy for Biomedical Studies

    Author : Stina Guldbrand; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two-Photon Excitation Microscopy; Fluorescence Correlation Spectroscopy; Multiphoton Luminescence; Human Skin; Gold nanoparticles;

    Abstract : This thesis is based on the application of non-linear optical microscopy and spectroscopy techniques within biomedical research. Non-linear optical microscopy gives the possibility of exciting fluorophores using near infrared light. READ MORE

  4. 4. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

    Author : Vladimir Kirejev; Göteborgs universitet.; Gothenburg University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

    Abstract : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. READ MORE

  5. 5. Functional Imaging of Spinal Locomotor Networks

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Chetan Nagaraja; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Central pattern generators; two-photon microscopy; locomotor rhythm; multiple rhythmicities; inhibitory neurotransmission; Neuroscience; Neurovetenskap;

    Abstract : Movement is necessary for the survival of most animals. The spinal cord contains neuronal networks that are capable of motor coordination and of producing different movements. In particular, a very reduced neuronal network in the spinal cord can produce simple rhythmic outputs even in the absence of descending or sensory inputs. READ MORE
