1. 1. Hyperemic Brachial Artery Blood Flow Velocity

   Författare :Susann J Järhult; Lars Lind; Johan Sundström; Peter Friberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Cardiovascular medicine; Kardiovaskulär medicin; Medicinsk vetenskap; Medical Science;

   Sammanfattning : This thesis aims to evaluate the blood flow velocity in the Brachial artery during reactive hyperemia. Primarily to appraise the information it might contain regarding cardiovascular function and cardiovascular risk. LÄS MER

3. 2. The regulation of muscle interstitial insulin, nutrients and blood flow in insulin resistant models. An investigation using the euglycemic insulin clamp and microdialysis techniques

   Författare :Maria Niklasson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin resistance; skeletal muscle; glucose uptake; transcapillary transport; interstitial fluid; euglycemic insulinclamp; microdialysis; blood flow; vasodilation;

   Sammanfattning : Insulin resistance, mainly located to the skeletal muscle tissue, is one prominent feature in thedevelopment of non insulin-dependent diabetes mellitus (NIDDM) and further, associated withcardiovascular diseases. In this context the importance of blood flow for insulin sensitivity has beensuggested by regulating the delivery of insulin and nutrients to the target cells. LÄS MER

4. 3. Studies on skin blood flow and evaporative water loss : a bioengineering approach

   Författare :Lena Nilsson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Skin blood flow (SBF), temperature, evaporative water loss (EWL) and skin conductance (SC) measured during stimulus-response experiments reveal valuable information regarding the skin's regulatory capacity. SBF and EWL play powerful roles in keeping the human body within an adequate temperature range. LÄS MER

5. 4. Neuropeptide Y - aspects of vasomotorresponses and receptor characterization

   Författare :Torun Nilsson-Bergdahl; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vasoconstriction; RT-PCR; receptor characterization; potentiation; NPY Y1 receptor; NPY; mitogenesis; hypertension; human arteries; forearm blood flow; cell culture; antisense oligodeoxynucleotides; BIBP3226; vasodilatation.; Physiology; Fysiologi; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

   Sammanfattning : Abstract The aims of the present thesis were to examine neuropeptide Y (NPY) responses in different human and guinea pig vascular beds and in cultured human vascular smooth muscle cells (VSMC) and to characterize, with different NPY agonists and the specific NPY Y1 receptor antagonist (BIBP3226), the NPY receptors involved. NPY-induced strong and potent contractions in human cerebral and subcutaneous arteries and in guinea pig basilar arteries. LÄS MER

7. 5. The hypertension-prone man: A study on the pathogenesis of hypertension with regard to insulin sensitivity

   Författare :Tomas Endre; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; sex steroid hormones; sodium retention; glycogen synthase; fibrinolysis; physical fitness; blood flow; insulin resistance; muscle fibres; Kardiovaskulära systemet;

   Sammanfattning : Hypertensive individuals, even non-obese, have been shown to be resistant to the insulin-mediated glucose uptake in peripheral tissues {mainly skeletal muscle}. The aim of this study was to investigate hypothetical pathophysiological mechanisms for the development of hypertension with regard to insulin sensitivity in normotensive men with a family history of hypertension (RELs) as compared to men with no such family history (CONs).
