  1. 6. Central neuropeptide Y (NPH) expression and function : role in stress, experimental anxiety, and cognition

    Författare :Annika Thorsell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :neuropeptide Y; stress; experimental anxiety; cognition; lipid-mediated gene transfer; transgenic animals; rat;

    Sammanfattning : Neuropeptide Y (NPY), a 36 amino acid peptide abundantly expressed throughout the mammalian nervous system, has been implicated in experimental anxiety and stress related responses, feeding, and learning and memory. These functions are mediated via different receptor subtype populations (Y1-Y6), all belonging to the G-protein coupled receptor superfamily. LÄS MER

  3. 7. Modulation of the HPA axis alters the sensitivity of the cochlea to acoustic trauma

    Författare :Yeasmin Tahera; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HPA axis; corticosterone; glucocorticoid receptor; NFêB; spiral ganglion neurons; cochlea; acoustic trauma; paraventricular nucleus;

    Sammanfattning : The hypothalamic pituitary adrenal axis (HPA axis) regulates nearly all neuroendocrine responses of the body. An active HPA axis is crucial to maintaining homeostasis. An altered reactivity of the HPA axis can affect several physiological systems including the auditory system. LÄS MER

  4. 8. Material Modelling of Adipose Tissue for Traffic Injury Prevention

    Författare :Hosein Naseri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element human body models; Global sensitivity analysis; Obesity; Adipose tissue; Constitutive modelling; Submarining;

    Sammanfattning : Traffic injury is one of the main reasons for traumatic injuries. Obese occupants are among the vulnerable populations with a higher risk of death and severe injuries. Notably, obesity is associated with a thick layer of subcutaneous adipose (fat) tissue. LÄS MER

  5. 9. Vippning av stålbalkar i hallramar

    Författare :Peter Collin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The present thesis, written in Swedish, deals with the problem of lateral-torsional buckling, especially in gable frames. The aim of the work presented is to suggest an improved design method that takes into account the translational and rotational restraint produced by the roof and wall. A particular question is the behaviour of the comer region. LÄS MER

  7. 10. Volunteer Muscle Activity in Dynamic Events. Input Data for Human Body Models

    Författare :Jóna Marin Olafsdottir; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; emergency braking; ative human body model; multidirectional perturbations; EMG; occupant kinematics; seatbelt pre-tension; reflex; validation data;

    Sammanfattning : Human body models (HBMs) are virtual human surrogates used to predict kinematic and injury responses during motor vehicle crashes. In recent years, active musculature has been incorporated into HBMs for enhanced biofidelity in simulated emergency scenarios, in particular low-severity crashes and pre-crash situations, where occupant responses are influenced by muscle tension.
