  1. 1. Frivilligt repetitivt muskelarbete under sex veckor förändrar kalciumkinetiken i sarkoplasmatiska retiklet hos råttor

    Kandidat-uppsats, Umeå universitet/Idrottsmedicin

    Författare :Adam Nordlund; Wilhelm Torshage; [2016]
    Nyckelord :Ca2 -uptake; Ca2 -release; muscle overuse; repetitive task; Sarcoplasmic reticulum;

    Sammanfattning : PURPOSE: Muscle overuse is characterized by inflammation, reduced strength and muscle damage. It has been proposed that calcium (Ca2+) accumulation during muscle contraction, is responsible for muscle damage. Muscle contractile properties are regulated by calcium regulatory excitation contraction coupling mechanisms. LÄS MER

  3. 2. Embryonic Gene Alterations in rats Caused by Exposure to Diabetes and/or Obesity

    Magister-uppsats, Institutionen för vård och natur

    Författare :Ehtesham Ehtesham; [2012]
    Nyckelord :;

    Sammanfattning : There is ample evidence that both diabetes as well as obesity leads to various metabolic disturbances that leads to oxidative stress. Oxidative stress has been shown  to  be  associated  with  congenital  malformations  of  which  neural  tube defects  and  cardiac  malformations  are  more  common. LÄS MER

  4. 3. Long-term depression in the rat hippocampus as a memory model : Interrogating the role of protein synthesis in NMDA- and mGluR-dependent synaptic plasticity

    Kandidat-uppsats, Institutionen för vård och natur

    Författare :Sameh Mohammad; [2010]
    Nyckelord :synaptic plasticity; NMDA; mGluR; Long-term depression; LTD; LTP; fEPSP; hippocampus; protein synthesis; cornu ammonis; plasticity related proteins; Sprague-Dawley rats; action potential;

    Sammanfattning : Long-term potentiation (LTP) and depression (LTD) are important forms of activity-dependent synaptic plasticity believed to play a role in memory at the cellular level. It has previously been described that synthesis of new proteins is needed to maintain LTP longer than a few hours. LÄS MER

  5. 4. Effects of three different housing systems on activity and physiological parameters in male Spontaneously Hypertensive rats and Sprague Dawley rats

    L3-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Christina Remes; [2007]
    Nyckelord :animal welfare; laboratory rats;

    Sammanfattning : Laboratory rats spend a majority of their lives in their home-cages. The cage often used for rats, Makrolon type IV, only gives them limited opportunities for physical activity. The welfare of the rats would increase by housing them in larger cages that allow an increased amount of physical activity. LÄS MER
