  1. 1. Physiological Stress Reactivity in Late Pregnancy

    Author : Charlotte Hellgren; Inger Sundström-Poromaa; Helena Åkerud; Mats Hammar; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acoustic startle response; allopregnanolone; antenatal; anxiety; cold pressor test; cortisol; cortisol awakening response; depression; electrodermal; estradiol; hypothalamic-pituitary-adrenal axis; postpartum; pregnancy; progesterone; skin conductance; stress; sympathetic nervous system; Medical Science; Medicinsk vetenskap;

    Abstract : During pregnancy, the basal activity is increased in both of our major stress response systems: the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. At the same time, the reactivity towards stressors is reduced. These alterations sustain maternal and fetal homeostasis, and are involved in the regulation of gestational length. READ MORE

  2. 2. Studies on Vitamin A Signaling in Psoriasis : A Comparison Between Normal and Lesional Keratinocytes

    Author : Teresa Karlsson; Jan Öivind Moskaug; Uppsala universitet; []
    Keywords : Medical sciences; Psoriasis; vitamin A; retinoids; retinoid receptor; differentiation; keratinocyte; skin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Dermatology and Venerology; dermatologi och venereologi;

    Abstract : Vitamin A and metabolites (retinoids) are crucial for normal epidermal maturation. Physiological effects are mediated by retinoic acid (RA) that activates nuclear retinoic acid receptors (RARs) in complexes with retinoid X receptors (RXRs), resulting in altered gene transcription.Psoriasis is a common disease with unknown etiology.

  3. 3. Toll-like receptor activation induced changes in dendritic cells

    Author : Oscar Hammarfjord; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Dendritic cells (DC) are professional antigen-presenting cells that act as a “bridge” between innate and adaptive immunity by the induction and subsequent orchestration of immune responses. The ligation of Toll-like receptors (TLR) and other innate receptors on DC determines their immune-stimulating capacity. READ MORE

  4. 4. Multivariate Data Analytics to Identify Driver’s Sleepiness, Cognitive load, and Stress

    Author : Shaibal Barua; Shahina Begum; Peter Funk; Mobyen Uddin Ahmed; Christer Ahlström; Nirmalie Wiratunga; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Driver monitoring; Driver state; Physiological signals; Machine learning; Contextual information; Computer Science; datavetenskap;

    Abstract : Driving a vehicle in a dynamic traffic environment requires continuous adaptation of a complex manifold of physiological and cognitive activities. Impaired driving due to, for example, sleepiness, inattention, cognitive load or stress, affects one’s ability to adapt, predict and react to upcoming traffic events. READ MORE

  5. 5. Epidermal keratinocytes studied by X-ray microanalysis, with special reference to contact dermatitis : In vivo and in vitro studies of functional changes in human cells

    Author : Anders Grängsjö; Uppsala universitet; []
    Keywords : Medical sciences; X-ray microanalysis; elements; epidermis; keratinocytes; proliferation; cell membrane damage; Ki67; irritants; intracellular elemental content; keratinocyte culture; HaCaT; NHEK; RT-PCR; immunohistochemistry; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; anatomi; Human Anatomy;

    Abstract : By determining the intracellular elemental content, information can be obtained on the physiological status of cells. The cellular content of sodium, magnesium, phosphorus, sulfur, chloride, potassium and calcium can be indicative for proliferation, cell membrane damage or cell death. READ MORE
