  1. 1. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle

    Författare :Asad Zeidan; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; SM22a; ERK1 2; caveolae; stretch; Smooth muscle; differentiation;

    Sammanfattning : Vascular smooth muscle can adapt to increased intraluminal pressure by remodelling and hypertrophy, as seen in hypertension. The molecular mechanisms responsible for this are still incompletely characterized. LÄS MER

  3. 2. Mechanosensing in the vascular wall - the role of cellular microdomains in vascular remodeling

    Författare :Sebastian Albinsson; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; cytochemistry; histochemistry; wall stress; shear stress; hypertension; Histology; differentiation; growth; caveolin; smooth muscle; actin; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : The vascular wall has a remarkable capacity to adapt to mechanical forces exerted by the intraluminal blood pressure and flow. This includes rapid change in contractile tone as well as chronic alteration of vessel structure if the stimulus persists. Stretch of the intact blood vessel wall promotes growth and contractile differentiation. LÄS MER

  4. 3. Vascular smooth muscle mechanotransduction and plasticity-the role of microRNA, calcium signaling and actin polymerization

    Författare :Karolina Turczynska; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PYK2; actin polymerization; calcium; microRNA; stretch;

    Sammanfattning : Smooth muscle cells residing in the blood vessel media are constantly exposed to mechanical forces exerted by the intraluminal pressure. The smooth muscle senses and adapts to mechanical forces by activation of multiple signaling pathways and cytoskeletal rearrangements. LÄS MER

  5. 4. Fastighetens gränser

    Författare :Kristin Land; Former name: Kristin Karlsson; Fastighetsvetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Lantmäteriverket har uttryckt en vision om koordinatbestämda fastighetsgränser, med avsikt att skapa en i gränshänseende korrekt digital registerkarta. Ett förverkligande av visionen skulle kräva en förändring av gällande rätt, eftersom dagens gränssystem bygger på principen att gränsmärken på marken gäller framför andra uppgifter om gränsers sträckning.

  7. 5. Correlation spectroscopy with epitaxial quantum dots : Single-photons alone in the dark

    Författare :Lucas Schweickert; Val Zwiller; Klaus D. Jöns; Richard J. Warburton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum dots; single--photons; indistinguishability; entanglement; Optik och fotonik; Optics and Photonics;

    Sammanfattning : The advent of quantum computation promises exciting advances, not only in fields like medicine and metrology, but many industries that rely on parameter-heavy calculations or simulation of molecular interaction. At the same time Shor's algorithm for quantum computers presents a threat to current asymmetric encryption protocols used in everyday communication. LÄS MER
