1. 1. Biomechanics of the Human Eye and Intraocular Pressure Measurements

   Författare :Darja Ljubimova; Anders Eriksson; Anders Eklund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IOP; GAT; ocular biomechanics; corneoscleral envelope; finite element modelling; parametric analysis; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : This thesis addresses the reliability of Goldmann-type applanation tonometers (GAT). It deals with the investigation of the relation between predicted intraocular pressure, IOPG and true pressure, IOPT. LÄS MER

3. 2. Biomechanical studies of finger extension function. Analysis with a new force measuring device and ultrasound examination in rheumatoid arthritis and healhty muscles

   Författare :Sofia Brorsson; Elena Gutierrez Farewik; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grip force; finger extension force; ultrasound; hand exercise; rheumatoid arthritis; muscle architecture; GAT; DASH; SF-36; Muscles;

   Sammanfattning : Aims: The overall aim of this thesis was to further our understanding of extensor muscles and their role for hand function. The aims of the studies were: To develop and evaluate a new device for finger extensor force measurements. To evaluate ultrasound as a tool for assessment of muscle architecture. LÄS MER

4. 3. GABA and human spermatozoa : characterization and regulation of GABA transport proteins

   Författare :Arthur Aanesen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :GABA; spermatozoa; GABA transport; acrosome reaction; sperm motility; progesterone; protein kinase C; GAT-1; GAT-2; GAT-3; BGT-1;

   Sammanfattning : The present project aimed at investigating the interaction between GABA and human spermatozoa under in vitro conditions. Our initial hypothesis was that human spermatozoa had specific binding proteins for GABA and that the binding of GABA to such binding sites could affect sperm function. LÄS MER

5. 4. Intraocular pressure : clinical aspects and new measurement methods

   Författare :Gauti Jóhannesson; Christina Lindén; Per Hallberg; Anders Eklund; Boel Bengtsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraocular pressure; glaucoma; tonometry; ISO; LASEK; CCT; curvature; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

   Sammanfattning : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment. In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland. LÄS MER

7. 5. The impact of gaze-based assistive technology on daily activities in children with severe physical impairments

   Författare :Maria Borgestig; Helena Hemmingsson; Torbjörn Falkmer; Jan Sandqvist; Gunnar Ahlsten; Idor Svensson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebral palsy; computer activities; daily activities; eye gaze control; self-help devices;

   Sammanfattning : Aim: The aim of the thesis was to investigate the impact of gaze-based assistive technology on daily activities in children with severe physical impairments and without speech. The objectives were to develop and pilot a gaze-based assistive technology intervention (GAT intervention) at home and in school for these children and to understand its impact on daily activities as experienced by their parents.
