  1. 1. Mechanisms of HAMLET-induced cancer cell death

    Författare :Sonja Aits; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-actinin; prohibitin; alpha-lactalbumin; HAMLET; cancer; cell death; autophagy; focal adhesions; c-Myc; hexokinase; glycolysis;

    Sammanfattning : HAMLET, a complex of α-lactalbumin and oleic acid, preferentially kills cancer cells and is also effective in vivo. HAMLET causes apoptosis but cells die even if this pathway is inhibited. Thus, the role of autophagy, an alternative cell death pathway, was examined. LÄS MER

  3. 2. Newborn respiratory support using distending pressure : the effect of interfaces and system design on performance and outcome

    Författare :Sonja Baldursdottir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Preterm infants often require respiratory support after birth due to lung immaturity. The preferred method of providing respiratory support to breathing infants in respiratory distress is non-invasively with continuous positive airway pressure (CPAP). LÄS MER

  4. 3. Coping with Misbehavior in Mobile Ad-hoc Networks

    Författare :Sonja Buchegger; Jean-Yves Le Boudec; EPFL; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mobile ad-hoc networks; incentives; cooperation; reputation systems; Bayes; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : n this work, we address the question of how to enable a system to operate despite the presence of misbehavior. Specifically, in a mobile ad-hoc network, how can we keep the network functional for normal nodes when other nodes do not route and forward correctly? Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. LÄS MER

  5. 4. Neonatal Exposure to Low-Dose Ionizing Radiation in Mice : Developmental Neurotoxic Effects of Single and Fractionated Doses and Interaction with Nicotine

    Författare :Sonja Buratovic; Per Eriksson; Jack Valentin; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : This thesis aims to investigate the developmental neurotoxic effects of low-dose exposure to ionizing radiation, alone or together with nicotine, during a defined critical period of neonatal brain development in mice. Investigation of neurotoxic effects following fractionated or acute low-dose radiation, resembling the clinical situation during repeated CT scans or radiation delivered to non-target tissue during radiotherapy, and possible interaction effects with other agents, is of great importance for risk and safety evaluation.
