  1. 26. The Human Spiral Ganglion

    Författare :Sven Tylstedt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. LÄS MER

  2. 27. Monoamine transporters in female human reproduction

    Författare :Barbara Bottalico; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PMAT; VMAT2; OCT; NET; in-situ hybridization histochemistry; decidualization; human endometrium; placenta; Medicine human and vertebrates ; Monoamine transporters; preeclampsia; histamine; Medicin människa och djur ;

    Sammanfattning : The present study explored the gene and protein expression of the monoamine transporters in human endometrium throughout the menstrual cycle, in early decidua and in placentas from normal as well as preeclamptic pregnancies using in-situ hybridization, real time-PCR, immunohistochemistry and primary tissue cultures. Four distinguishable patterns were observed in the endometrium over the menstrual cycle: (1) epithelial expression of norepinephrine transporter (NET) mRNA, (2) Stromal co- expression of vesicular monoamine transporter 2 (VMAT2) and plasma membrane monoamine transporter (PMAT) mRNAs with maximal intensity in the proliferative phase; (3) increasing epithelial expression of VMAT2 mRNA with a maximum in the late secretory phase; (4) stromal expression of extra-neuronal monoamine transporter (EMT) mRNA with a peak in the early secretory phase.

  3. 28. Tissue engineering in blood vessels

    Författare :Gisela Helenius; Göteborgs universitet; []
    Nyckelord :tissue engineering; vascular graft; endothelial cells; smooth muscle cells; thrombogenicity; mechanical properties; scaffold; bacterial cellulose;

    Sammanfattning : Severely occluded coronary- and peripheral arteries, caused by atherosclerotic plaques, are treated with bypass surgery. Autologous veins are the most commonly used replacement graft. Among the patients that need a vascular bypass, 5-10% lack appropriate replacement veins due to previous surgery of bad quality of the vessels. LÄS MER

  4. 29. The role of galectin-1 in type 2 diabetes. Clinical and experimental studies

    Författare :Emanuel Fryk; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; galectin-1; type 2 diabetes; human; adipose tissue; metabolism;

    Sammanfattning : Aim: The purpose of this thesis was to identify a new agent in the subcutaneous adipose tissue and assess its clinical potential in the context of type 2 diabetes. Study I: Through a combination of microdialysis and mass-spectrometry, we found increased galectin-1 levels in the subcutaneous adipose tissue in a small experimental study of 15 men with and without type 2 diabetes.

  5. 30. The kallikrein-kinin system in primary hypertension : dynamics of circulating components of the kallikrein-kinin system in relation to the renin-angiotensin-aldosterone system

    Författare :K. Peter Öhman; Linköpings universitet; []
    Nyckelord :aldosterone; angiotensin Il; blood pressure; human; prekallikrein; renin; tissue kallikrein; MEDICINE; MEDICIN;

    Sammanfattning : Kinins are potent vasodilatory and blood pressure lowering peptides, with additional effects on renal handling of electrolytes and water. The kallikrein-kinin system consists of two separate entities, one confined to the circulation and the other to both tissues and the circulation. LÄS MER
