  1. 1. Adult Stem Cell Plasticity, Hype or Hope?

    Författare :Jalal Taneera; diabetes och endokrinologi Genomik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; pancreatic beta cell ; stem cell ; plasticity ; Medicin människa och djur ;

    Sammanfattning : Several studies have reported that bone marrow (BM)-derived stem cells have the capacity to give rise to cells of different type of tissue; an ability termed stem cell plasticity or transdifferentiation. Controversies exist as to how frequent this phenomenon is, or if it may be explained by alternative mechanisms. LÄS MER

  3. 2. Studies of the role of complement factor H in hemolytic uremic syndrome

    Författare :Fariba Vaziri Sani; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatri; Pediatrics; Hemolytic uremic syndrome; complement system; factor H;

    Sammanfattning : Factor H is the main fluid phase regulator of the alternative pathway of complement. Factor H acts as a co-factor for factor I-mediated C3b degradation, inhibits the formation of the C3bBb convertase and accelerates its decay. By discriminating between host and foreign cells, factor H inhibits complement-mediated injury to host cells. LÄS MER

  4. 3. Direct and endothelium-linked serotonergic control of vascular tone in human uterine and umbilical arteries

    Författare :Caroline Karlsson; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; vascular smooth muscle; uterine artery human ; umbilical artery human ; serotonergic receptor; 5-HT; noradrenaline; endothelium; NPY; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : The serotonergic vascular control was investigated by in vitro pharmacology in the human uterine and umbilical arteries. The localisation of immunoreactive (IR) neuropeptide Y (NPY) and the influence of NPY on the adrenergic vascular effects in the human uterine artery were also studied. LÄS MER

  5. 4. Prevention of intimal hyperplasia after balloon angioplasty and / or stent insertion. or How to mend a broken heart - Just say NO

    Författare :Jan Harnek; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Remodeling. Endothelium-derived factors. Self-expanding stents. Restenosis. Scanning -electron microscopy. Endothelial factors. Nitric oxide. Intimal hyperplasia. Angioplasty. Stents. Interventional procedures. Endothelium.;

    Sammanfattning : Background: Restenosis is the most frequently occurring adverse event after percutaneous intravascular treatment of atherosclerotic lesions, which limits long-term patency of the intervention. Objective: The aim of the study was to evaluate if minimizing vascular injury during treatment by insertion of self-expanding stents or modifying the reparative mechanisms by local drug delivery can reduce restenosis.

  7. 5. Intestinal Ischemia and Reperfusion Injury - Pathophysiology as basis for novel treatment

    Författare :Zhengwu Sun; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; organ dysfunction; epithelium; endothelium; adhesion molecules; cytokines; protease inhibitor; Intestine; barrier; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Intestinal ischemia and reperfusion (I/R) is not infrequent in the clinical situation and the intestinal barrier plays an important role in gut barrier function, preventing not at least septic complications and potentially the development of the multiple organ dysfunction syndrome. Mechanisms of intestinal I/R induced gut epithelial and endothelial barrier dysfunction and remote organ dysfunction, as well as potential preventive and therapeutic modes of management were evaluated in the rat.
