1. 6. The effects of reactive oxygen species and lipofuscin on the function and health of the retinal pigment epithelium

   Författare :Ulf Wihlmark; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Age-related macular degeneration (ARJVID) is a common cause of central vision loss in elderly people. Specific treatment is possible only for selected patients. A dysfunction of the retinal pigment epithelial (RPE) cells has been proposed to help explain the pathogenesis of ARMD. LÄS MER

3. 7. Morphometrical Methodology in Quantification of Biological Tissue Components

   Författare :Bo Blomgren; Godfried Roomans; Christian Falconer; Marita Hilliges; Steven Campbell; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Morphometry; Stereology; Image analysis; histology; Bildanalys; Image analysis; Bildanalys;

   Sammanfattning : Objective:To develop and validate computer-assisted morphometrical methods, based on stereological theory, in order to facilitate the analysis and quantitative measurements of biological tissue components.Material and methods:Biopsy specimens from the vaginal wall or from the vestibulum vaginae of healthy women, or from women suffering from incontinence or vestibulitis were used.

4. 8. Spectroscopic Measurements and Fluorescence Imaging for Treatment and Diagnosis of Skin Cancer

   Författare :Marica Ericson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis deals with the use of light for treatment and diagnosis of skin cancer. The occurrence of skin cancer is increasing worldwide, among the most common types being basal cell carcinoma, squamous cell carcinoma and actinic keratosis, a skin cancer precursor. LÄS MER

5. 9. Studies of optical properties of lanthanide upconversion nanoparticles for emerging applications

   Författare :Qingyun Liu; Hans Ågren; Haichun Liu; Patricia Haro Gonzalez; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Upconversion nanoparticles; solar cells sensitization; near infrared photodetector; multiplex imaging; optical encoding; information technology; bioimaging; rate equation models; Theoretical Chemistry and Biology; Teoretisk kemi och biologi;

   Sammanfattning : YTTERBY, a small village very close to Stockholm where I live, is the place in the world which has lent its name to the largest number of elements in the periodic table, namely four - YTTRIUM, YTTERBIUM, ERBIUM and TERBIUM. Three more lanthanide elements were discovered from the now empty quarry located in this village. LÄS MER
