  2. 1. Intestinal Permeability and Presystemic Extraction of Fexofenadine and R/S-verapamil

    Author : Christer Tannergren; Hans Lennernäs; Dirk KF Meijer; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; Bioavailability; Fexofenadine; Verapamil; P-glycoprotein; CYP3A4; OATP; Enantioselective; Permeability; Caco-2; Intestinal perfusion; Biofarmaci; Biopharmacy; Biofarmaci;

    Abstract : The main objective of this thesis was to investigate the in vivo relevance of membrane transporters and cytochrome P450 (CYP) 3A4-mediated metabolism in the intestine and liver for the bioavailability of drugs in humans after oral administration.In the first part of the thesis, the main transport mechanisms involved in the intestinal absorption and bioavailability were investigated for fexofenadine, a minimally metabolized drug, which is a substrate for P-glycoprotein (P-gp) and members of organic anion transporting polypeptide (OATP) family.

    Abstract : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. READ MORE

  5. 3. Channel Estimation and Self-Interference Suppression for MIMO Relaying Systems

    Author : Panagiota Lioliou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation; expectation-maximization EM ; half-duplex; Bayesian; multiple-input multiple-output MIMO ; Cramer-Rao Bound CRB ; full-duplex; relays; performance analysis; Kalman filter KF ; self-interference.; Amplify-and-forward AF ; least squares LS ;

    Abstract : Recently, the introduction of relaying nodes in wireless channels has been identified as a promising technique for providing broader coverage, higher transmission rates, and increased reliability. Moreover, when the concept of relaying systems is combined with that of multiple-input multiple-output (MIMO) technology, thesystem performance can be further improved by exploiting the spatial dimension.

  6. 4. An Investigation of the Influence of Knee Flexion Angle on the Activity of the Triceps Surae Muscles during the Heel-Raise Test

    Author : Kim Hébert-Losier; S. John Sullivan; Anthony G. Schneiders; José A. García; Univeristy of Otago; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomechanics; Electromyography; Triceps surae; Achilles tendon; Plantar flexion; Heel raise test; Physiotherapy; Rehabilitation; Musculoskeletal; Movement analysis; Muscle endurance; Maximum voluntary isometric contraction;

    Abstract : Background: The heel-raise test (HRT) is used in clinical practice and research to assess the triceps suare (TS) muscles. The test involves repetitive unilateral heel-raises in upright stance. The test is administered with the knee straight for gastrocnemius medialis (GM) and lateralis (GL), and with the knee bent for soleus (SOL). READ MORE

  7. 5. Advanced Kalman Filtering Approaches to Bayesian State Estimation
