    Abstract : Popular Abstract in Swedish Njurarnas huvudsakliga funktion i kroppen är att rena blodet från slaggprodukter och reglera vätskebalansen. Hos patienter med nedsatt njurfunktion måste blodet renas på alternativa sätt. READ MORE

  2. 2. Blood-Brain Barrier Transport Investigation of Active Efflux using Positron Emission Tomography and Modelling Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Stina Syvänen; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; pharmacokinetics; P-glycoprotein; blood-brain barrier; modelling; PET; active efflux; species differences; [11C]verapamil; drug development; Farmaceutisk biovetenskap;

    Abstract : This thesis examines the transport of exogenous molecules across the blood-brain barrier (BBB), focusing on active efflux, using positron emission tomography (PET), computer simulation and modelling. P-glycoprotein (P-gp) inhibition was studied using [11C]verapamil and [11C]hydroxyurea was investigated as a new marker for active efflux transport. READ MORE

  3. 3. Loyal Speed Adaptation Speed limitation by means of an active accelerator and its possible impacts in built-up areas

    University dissertation from Traffic Engineering

    Author : Sverker Almqvist; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active accelerator; LSA; speed; speed reduction; driver behaviour; traffic safety; ISA; Teknik; Technological sciences; Road transport technology; Vägtransportteknik;

    Abstract : Traditional measures for improved traffic safety need to be complemented by modern technologies in the struggle to reduce the consequences of traffic accidents all over the world. This thesis introduces the Loyal Speed Adaptation (LSA) function based on recent developments in the area of Intelligent Transport Sys-tems to support the vehicle drivers in not using inappropriate or excessive speeds, which have been found to be an important factor for causing serious and fatal accidents.

  4. 4. Towards a capability approach to mobility : An analysis of disparities in mobility opportunities among older people

    University dissertation from Department of Technology and Society, Lund University

    Author : Jean Ryan; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2019-02-20]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; Ageing; Transport equity; Capability Approach; Public transport; Cycling; Older people;

    Abstract : The overall aim of this thesis is to gain a clearer picture of the differences in mobility among the young-old living in Sweden’s large metropolitan regions. This thesis comprises four papers. Paper I explores the inclusion of public transport as an element of mobility among the young-old living in the Stockholm region. READ MORE

  5. 5. In Vivo Active Drug Uptake and Efflux at the Blood-Brain Barrier With Focus on Drug Transport Interactions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Muhammad Waqas Sadiq; Uppsala universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Active uptake transport; Microdialysis; P-glycoprotein; Drug interactions; Species differences; Pharmacokinetics; Pharmacodynamics; NONMEM; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : The blood-brain barrier (BBB) controls the movement of substances into and out of the brain. The tight junctions between endothelial cells and energy dependent transporters in the BBB influence rate and extent of drug distribution to the brain. READ MORE
