  2. 1. Mechanisms of Osseointegration: Experimental Studies on Early Cellular and Molecular Events in vivo

    Author : Omar Omar; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; bone; gene expression; bone-implant interface; qPCR; inflammation; cytokine; chemotaxis; chemokine; integrin; bone formation; remodeling; in vivo; rat; immunohistochemistry; ultrastructure; biomechanical torque test;

    Abstract : The early cellular and molecular activities determining the early tissue response and bone formation at bone/implant interface are not fully understood. The general aim of the current thesis was to develop a model for studying the early molecular and cellular activities in different bone types, and in response to different implant surface properties.

  4. 2. Just Waiting : Ethical Challenges in Priority Setting Posed by Organ Scarcity in Kidney Transplantation

    Author : Faisal Omar; Stellan Welin; Per Carlsson; Jan Erik Paulsen; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : Over the last few decades kidney transplantation has transformed from an experimental treatment to the treatment of choice for end-stage renal disease. Unfortunately, however, the established organ donation models in many countries, relying chiefly on altruism, fail to motivate a sufficient number of donors. READ MORE

  5. 3. The development of methods for detection and assessment of safety critical events in car driving

    Author : Omar Bagdadi; Andras Varhelyi; Nicolas Saunier; Statens väg- och transportforskningsinstitut; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Near miss; Braking; Driving veh ; Driver; Behaviour; Tillbud; Bromsning; Fordonskörning; Förare; Beteende; Road: Road user behaviour; Road: Road user behaviour; Crash involvement; jerk; safety critical event;

    Abstract : Improving our knowledge of drivers’ behaviour, especially in hazardous situations is a key to understanding why accidents occur and how to improve safety on our roads. Crash surrogate measures have proven to be very useful in traffic safety analysis. READ MORE

  6. 4. Growth and Survival : Child Health Disparities and Early Life Adversity in Sub-Saharan Africa

    Author : Omar Karlsson; Centrum för ekonomisk demografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; child health; under-mortality; sub-Saharan Africa; low-and-middle-income countries; parental factors;

    Abstract : Sound physical health is a critical component of the human development process, wherein early life and childhood are pivotal periods. Although child health in sub-Saharan Africa has been improving for the past few decades, the region still has the highest mortality rate for children under five as well as high levels of child morbidity.

  7. 5. Radiation dose and x-ray beam modelling in diagnostic and interventional radiology using Monte Carlo methods

    Author : Artur Omar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Although medical imaging is essential for the diagnosis and treatment of a wide range of medical conditions, the radiation dose from x-ray examinations is one of the largest contributors to the exposure of the world’s population. It is therefore the responsibility of healthcare professionals to ensure that examinations are justified (a net benefit) and optimized (as low dose as reasonably achievable). READ MORE
