1. 1. Cardiac Resynchronization Therapy - Risk Stratification and Long-Term Outcome

   Författare :Christian Reitan; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac Resynchronization Therapy; heart Failure; Device therapy; long-term outcome;

   Sammanfattning : Heart failure is a condition that will affect 2-3% of the population. Around one third of the patients have a decreased LVEF and a widened QRS complex as a sign of ventricular dyssynchrony. CRT has emerged as a treatment that reduces morbidity, mortality and improve functional status in this population. LÄS MER

3. 2. A tailored biocompatible neural interface for long term monitoring in neural networks

   Författare :Per Köhler; Neuronano Research Center (NRC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-machine interfaces; neuroinflammation; somatosensory cortex; hyperalgesia; allodynia;

   Sammanfattning : Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. LÄS MER

4. 3. The Bone Conduction Implant (BCI) - Preclinical Studies, Technical Design and a Clinical Evaluation

   Författare :Hamidreza Taghavi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bone conduction implant; Amplitude modulation; Bone anchored hearing aid; Radio frequency power amplifier and inductive link; Long-term implantation.; Low-power systems; Implanted transducer;

   Sammanfattning : The Bone Conduction Implant (BCI) system has been developed as an alternative to the percutaneous bone anchored hearing aid (BAHA) with the advantage that the skin is kept intact. The transducer is permanently implanted and attached to the skull via a flat surface contact to the temporal bone. LÄS MER

5. 4. Long-term results of phakic refractive lenses (PRL) for correction of myopia and hyperopia

   Författare :Annemari Koivula; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The phakic refractive lens (PRL) is a silicone lens implanted into the posterior chamber to correct myopia and hyperopia. At the beginning of 2002, when the PRL was introduced at St. LÄS MER

7. 5. The Human Cochlea and Cochlear Implantation : Morphological Characteristics and Clinical Correlations

   Författare :Nadine Schart-Morén; Helge Rask-Andersen; Elina Mäki-Torkko; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cochlear implantation; micro-CT; synchrotron; facial nerve stimulation; hearing preservation; round window;

   Sammanfattning : The most common sensory deficit in the world is sensorineural hearing loss. Cochlear implantation (CI) can majorly contribute to restore hearing, not only in patients with severe to profound hearing loss, but also in hearing-impaired patients with residual low-frequency hearing.
