    Författare :Bei Wang; Klas Hjort; Zhigang Wu; Magnus Berggren; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser patterning; sacrificial mask; liquid metal; strain sensor; skin movement; masking; shrink film; 3D conformal masking; liquid metal particles; soft electronics; stretchable electronics; compliant electronics; skin-like electronics; epidermal electronics; micro-heater; particle sintering; enteroendocrine cells; localized ectopic expression; wettability; flexography printing; conformal transfer printing; hydro printing; plant physiology; drosophila;

    Sammanfattning : Skin-like electronics could provide a soft and gentle contact with living beings for perceiving and delivering the information of pressure, strain, temperature with higher spatial resolution and sensitivity than our skin, without disturbing the user. Gallium-based liquid metal (LM) is an excellent material for soft and stretchable skin-like devices, since it has high electrical and thermal conductivity, flowability, and self-healable capability.

  3. 2. Molecular regulation of hormone secretion, growth and apoptosis of GLP-1-producing cells

    Författare :Camilla Kappe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Type 2 diabetes (T2D) spreads like an epidemic in today’s society, and there is a great need for new and improved treatments. T2D is characterized by hyperglycemia, resulting from impaired insulin production and insulin resistance in peripheral tissues. LÄS MER

  4. 3. Studies on the effect of orexin on upper gastrointestinal function in rats and man

    Författare :Marcus Ehrström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Orexin A; orexin receptors; SB-334867-A enteric ganglia; enteroendocrine cells; migrating myoelectric complex; nitric oxide; gastric emptying; gastric acid secretion; leptin; insulin;

    Sammanfattning : Aims: To define the morphological localisation of orexin A (OXA) in the gut, and study the effect of endogenous and peripherally administered OXA on fasting small bowel motility, gastric emptying and acid secretion, hormones involved in glucose homeostasis and pharmacokinetic profile of OXA in rats and humans. Methods: The distribution of OXA, orexin receptors 1 and 2 (OX1 R, OX2R), neuronal nitric oxide synthase (nNOS) and various peptides were studied with immunocytochemistry in rat and human gut.

  5. 4. Cellular and molecular mechanisms in the pathogenesis of irritable bowel syndrome

    Författare :Ghazaleh Mohammadian Kermani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Irritable bowel syndrome (IBS) is part of the functional bowel disorder spectrum with no single accepted theory of its development and no biological marker for diagnosis. Today the diagnosis is defined by the ROME criteria, but this is not always correlated to the diagnosis the clinician gives. LÄS MER

  7. 5. Capsid protein functions of enteric human adenoviruses

    Författare :Anandi Rajan; Niklas Arnberg; Stefan Schwartz; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; gastroenteritis; capsid proteins; receptor; integrins; heparan sulfate; sialic acid;

    Sammanfattning : Human adenoviruses (HAdVs) cause respiratory illnesses, epidemic conjunctivitis and infantile gastroenteritis. HAdV types 40 and 41 cause enteric infections in infants worldwide. HAdVs use various receptors for attachment onto different host cells. LÄS MER
