  2. 1. An Analysis of NMRD profiles and ESR lineshapes of MRI Contrast Agents

    Author : Xiangzhi Zhou; Per-Olof Westlund; Jozef Kowalewski; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; MRI contrast agent; MS-325; Spin relaxation; NMRD; ESR; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : To optimize contrast agent in MRI scan region, e.g. to enhance paramagnetic relaxation in the MRI scan fields(0.1T-3T), one possible way is to slow down the tumbling of the paramagnetic complex. READ MORE

  4. 2. Molecular dynamics in membrane systems : an ESR spin label study

    Author : Magdalena Ehrström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The ESR spin labeling technique has been used to investigate order and motion in medel lipid systems and in biological membranes under various experimental conditions.The effects of CaCl2, MgCl2, LaCl3 and some alkali halides on B. READ MORE

  5. 3. Renal cell carcinoma : factors of importance for follow-up and survival

    Author : Farhood Iranparvar Alamdari; Börje Ljungberg; Torgny Rasmuson; Sven Lundstam; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; renal cell carcinoma; follow-up; VEGFR-1; PS; ESR; stage; prognosis; metastasis; surveillance; TNM classification; adrenalectomy; angiogenesis; VEGF; Urology and andrology; Urologi och andrologi;

    Abstract : Background: Renal cell carcinoma (RCC) is most lethal of the urological cancers, with more than 40% dying of the disease. About 30% of the patients have metastases at initial diagnosis and up to 40% undergoing nephrectomy for localized RCC develop metastasis. READ MORE

  6. 4. Water Relaxation Processes as Seen by NMR Spectroscopy Using MD and BD Simulations

    Author : Ken Åman; Per-Olof Westlund; Arnold Maliniak; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; NMR; Stochastic Liouville Equation; Brownian Dynamics; Molecular Dynamics; Water; Relaxation; Deuterium; ESR; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis describes water proton and deuterium relaxation processes, as seen by Nuclear Magnetic Resonance (NMR) spectroscopy, using Brownian Dynamics (BD) or Molecular Dynamics (MD) simulations. The MD simulations reveal new detailed information about the dynamics and order of water molecules outside of a lipid bilayer. READ MORE

  7. 5. Effect of Ischaemia-Reperfusion on Rabbit Kidney and Human Brain

    Author : Jagdish Shivlal Gondalia; Göteborgs universitet; []
    Keywords : Free radicals; ischaemia-reperfusion; cell bioenergetics; NMR; ESR; carotid artery stenosis; endarterectomy; allopurinol; acetylcysteine; MMP-1; ICAM-1; MCP-9; oxLDL;

    Abstract : Free radicals are produced in various organs at ischaemia-reperfusion. The final stage in radical damage is lipid peroxidation. We have demonstrated previously that a lipid-soluble antioxidant improves restoration of bioenergetics in rabbit kidneys after ischaemia, as reflected in 31P spectrometry. READ MORE
