  2. 21. Receptor-mediated uterine effects of oxytocin and vasopressin

    Author : Ragner Liedman; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurohypophyseal; vasopressin receptor; oxytocin; pregnancy; oxytocin and vasopressin V1a antagonist; prostaglandin F2 alpha; primary dysmenorrhoea;

    Abstract : The neurohypophyseal hormones oxytocin and vasopressin are important in the regulation of uterine contractility. These hormones, as well as prostaglandin F2α, are most forceful myometrial tissue contractors. READ MORE

  4. 22. Effects of Rho kinase, prostacyclin and L-arginine on microvascular permeability and perfusion

    Author : Cornelia Lundblad; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; skeletal muscle; Rho kinase; prostacyclin; permeability; NO; experimental brain trauma; brain edema; brain contusion; microcirculation; cerebral perfusion;

    Abstract : This thesis presents some effects of Rho kinase, prostacyclin (PGI2) and nitric oxide (NO) in relation to trauma and inflammation by evaluating their effects on microvascular perfusion and permeability in mouse brain and in cat skeletal muscle. PGI2 and NO are endogenous vasoactive substances produced by the endothelium. READ MORE

  5. 23. Celluar and Molecular Mechanisms Underlying Regulation of Skeletal Muscle Contraction in Health and Disease

    Author : Mingxin Li; Lars Larsson; Tomas Winkler; Alf Månsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scaling; myosin heavy chain; in vitro motility assay; myopathy; Clinical neurophysiology; Klinisk neurofysiologi; Neuroscience; Neurovetenskap;

    Abstract : Morphological changes, genetic modifications, and cell functional alterations are not always parallel. Therefore, assessment of skeletal muscle function is an integral part of the etiological approach. READ MORE

  6. 24. Novel markers for smooth muscle cell modulation in vascular injury and disease

    Author : Urszula Rykaczewska; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Smooth muscle cells (SMCs) are major constituents of the vascular wall, indispensable for basic physiological functions of a healthy vessel, such as regulating vascular tone and blood pressure, but also critical during disease development. With remarkable plasticity, SMCs act as early responders to vessel wall injury, where by activating molecular mechanisms, including phenotypic modulation and transdifferentiation, they counteract detrimental stimuli and aim to restore vascular homeostasis.

  7. 25. Maternal obesity, duration of labor and the role of leptin

    Author : Sara Carlhäll; Marie Blomberg; Karin Källén; Jan Brynhildsen; Karin Pettersson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background: The prevalence of obesity substantially increases in pregnant women. Maternal obesity is associated with adverse maternal and neonatal outcomes. The increased risk for cesarean section present in obese women has been related to potential impaired uterine contractility. The mechanism that underlies this theory is not clear. READ MORE
