1. 6. Optical spectroscopy and fluorescence imaging for cancer diagnostics

   Författare :Pontus Svenmarker; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomedical optics; Diffuse-reflection spectroscopy; Upconverting nanoparticles; Inverse problem; Fluorescence; Tomography; Imaging; Scattering media; Photon migration; Fysicumarkivet A:2012:Svenmarker;

   Sammanfattning : This work presents optical methods for diagnosing cancer. A complementary method for diagnosing eye cancer was investigated using a technique developed within this work named transscleral optical spectroscopy (TOS). LÄS MER

3. 7. Congenital and Childhood Myotonic Dystrophy type 1 - the impact on central nervous system, visual and motor function

   Författare :Anne-Berit Ekström; Göteborgs universitet; []
   Nyckelord :myotonic dystrophy type 1; children; muscle strength; motor function; autism spectrum conditions; learning disability; adaptive skills; visual impairment; hyperopia;

   Sammanfattning : Background and aims: Myotonic dystrophy type 1 (DM1) is an autosomal dominant multisystemic disorder, caused by an expanded CTG repeat on chromosome 19. The disorder can present both in children and adults. LÄS MER

4. 8. On the identification of visual defects in children in general and prematurely born children in particular

   Författare :Anna-Lena Hård; Göteborgs universitet; []
   Nyckelord :preschool vision screening; referral criteria; children; vision; preterm; cerebral visual impairment; visual perception; ocular fundus morphology;

   Sammanfattning : Aims: Papers I & II: To evaluate the consequences of changes in the criteria for referral to an eye clinic following general pre-school vision screening. According to the former criteria all 4 year old children in the Göteborg area, with visual acuity (VA) ... LÄS MER

5. 9. Experimental transplantation of retinal and iris pigment epithelial cells into the subretinal space

   Författare :Sven Crafoord; Jan Ulrik Prause; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : A dysfunction of the retinal pigment epithelium (RPE) is the main cause for the development of age-related macular degeneration (ARMD) and visual loss in elderly people. For about 10 years experimental and clinical attempts to transplant RPE cells have been performed. LÄS MER

7. 10. Diffuse Optical Spectroscopy and Imaging of Turbid Media

   Författare :Can Xu; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; upconverting nanoparticles; luminescence; fluorescence; inverse problem; diffuse reflection spectroscopy; biomedical optics; photon migration; biomedical imaging; gas spectroscopy; medical diagnostics; tomography; Fysicumarkivet A:2013:Xu;

   Sammanfattning : This thesis deals with optical spectroscopy and imaging of complex and strongly scattering turbid media. Focus is mainly placed on three topics, being i) diffuse optical spectroscopy of choroidal tumors, ii) gas spectroscopy in scattering materials using the GASMAS (gas in scattering media absorption spectroscopy) technique, and iii) luminescence diffuse optical imaging and tomography of tissues.
