  2. 1. Stress and the Offspring : Adaptive Transgenerational Effects of Unpredictability on Behaviour and Gene Expression in Chickens (Gallus gallus)

    Author : Daniel Nätt; Per Jensen; Berry Spruijt; Linköpings universitet; []
    Keywords : Chicken; Red junglefowl; Domestication; Epigenetics; Transgenerational; Inheritance; Gene expression; Microarray; qRT-PCR; Immunogenetics; Immunoglobulin; Estradiol; Steriod hormones; Prenatal stress; Epigenetic inheritance; Adaptation; Stress; Behaviour; Ethology of domestic animals; Husdjurens etologi;

    Abstract : Environmental stress has shown to affect both the exposed individuals and the development of their offspring. Generally, it is thought that the stressed organism responds to stress by trying to adapt to it. READ MORE

  4. 2. Exosomes and the NKG2D receptor-ligand system in pregnancy and cancer : using stress for survival

    Author : Malin Hedlund; Lucia Mincheva-Nilsson; Susanne Gabrielsson; Umeå universitet; []
    Keywords : Exsosomes; NKG2D; MICA; MICB; ULBP; human placenta; trophoblast; syncytiotrophoblast; thermal stress; oxidative stress; leukemia; lymphoma; immunologi; Immunology;

    Abstract : Although not obvious at first sight, several parallels can be drawn between pregnancy andcancer. Many proliferative, invasive and immune tolerance mechanisms that supportnormal pregnancy are also exploited by malignancies to establish a nutrient supply andevade or edit the immune response of the host.

  6. 4. Self-help via the Internet : A new approach to psychological treatment

    Author : Lars Ström; Gerhard Andersson; Jeff Richards; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psychotherapy; Internet; treatment; sleep disorder; insomnia; stress management; stress; headache; drop-out; self-help; minimal therapist contact; Psykoterapi; Psychiatry; Psykiatri;

    Abstract : During the last 30 years, studies have shown self-help to be effective in a number of areas, and to produce equal or close to equal results compared to face-to-face therapy. The Internet can reach a large number of people at a low cost and add the possibility of two-way communication to self-help, thereby offering cost-effective psychological treatments. READ MORE

  7. 5. Wheel-rail contact modelling in vehicle dynamics simulation

    Author : Matin Shahzamanian Sichani; Mats Berg; Roger Enblom; Elena Kabo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; non-elliptic contact; vehicle-track interaction; rail vehicle dynamics; rolling contact; MBS; virtual penetration; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena. READ MORE
