   Författare :Anna Malmros; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ohmic contact; TFR; TiN; HEMT; GaN; TaN;

   Sammanfattning : Gallium nitride (GaN) based high electron mobility transistor (HEMT) technology has attracted much attention during the last decade which has resulted in a rapid development in material quality and device performance. GaN HEMT microwave electronics are currently finding its applications in wireless communication infrastructure and radar systems. LÄS MER

3. 2. Development of SiC MESFET Based MMIC Technology

   Författare :Mattias Sudow; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIM capacitor; high power amplifier; limiter; SiC MMIC; SiC MESFET; SiC Schottky; TFR; high levelmixer; spiral inductor; via-hole;

   Sammanfattning : A SiC MESFET based MMIC process has been successfully developed. This technology has its main potential in high power microwave circuits. It will offer the benefits of the high integration seen in GaAs MMIC at the same time as it will offer the benefits of the high voltage operation seen in Si LDMOS and Si BJTs. LÄS MER

4. 3. Harnessing the molecular Trojan horse : Evaluating properties of preclinical Aβ immunoPET radioligands for optimized brain delivery via the transferrin receptor

   Författare :Gillian Bonvicini; Stina Syvänen; Johanna Fälting; Dag Sehlin; Ken Honek; Sahar Roshanbin; Joy Zuchero; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transferrin receptor TfR ; bispecific antibody; brain delivery; positron emission tomography PET ; Alzheimer’s disease; pharmacokinetics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

   Sammanfattning : With high specificity and selectivity to targets, antibodies are prime candidates for positron emission tomography (PET) radioligands. They do not passively cross the blood-brain barrier which has hindered their development for imaging intrabrain targets, like amyloid-β (Aβ) in Alzheimer’s disease. LÄS MER

5. 4. Design, expression, and analysis of antibody-based blood-brain barrier shuttles

   Författare :Andrés de la Rosa; Greta Hultqvist; Paul O'Callaghan; Nicole G. Metzendorf; Torben Moos; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibody therapeutics; transient gene expression; protein production; blood-brain barri-er BBB ; BBB shuttle; brain delivery; Transferrin receptor TfR ; heparan sulfate; holo-transferrin; Molekylär biovetenskap; Molecular Life Sciences;

   Sammanfattning : Antibody therapeutics, with their strong and highly selective target binding, are now used to treat various diseases. However, to enable their use to treat brain disorders, they must be delivered across the blood-brain barrier (BBB), as without active transport, only around 0.01% of intravenously injected doses reach the brain.
