  2. 16. Studies of diaphragm fatigue and dysfunction

    Author : Peter J Radell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Diaphragm function; contractility; fatigue; oxidative metabolism; 31phosphorus nuclear magnetic spectroscopy; ultrasonography; prolonged ventilation; compound muscle action potential; myopathy; electroneurography; muscle fiber; morphology.;

    Abstract : Diaphragm fatigue and dysfunction are important components of acute and chronic respiratory pump failure. We lack knowledge about the nature of diaphragm fatigue and the pathophysiological and morphological changes that occur in the diaphragm after prolonged mechanical ventilation. This thesis studied two aspects of diaphragm function. READ MORE

  4. 17. Improving medical abortion : using mifepristone in combination with a prostaglandin analogue

    Author : Christian Fiala; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Medical abortion; mifepristone; misoprostol; slow release; home use; hCG; ultrasound; verification of expulsion; non-steroidal anti-inflammatory drug; pain relief; second trimester; uterine contractility; acceptability;

    Abstract : Background: Induced abortion is still a major health problem in the world and the most frequently performed intervention in Obstetrics and Gynaecology with an estimated total of 46 millions worldwide each year. Medical abortion with mifepristone and prostaglandin was first introduced in 1988, and is now approved in 29 countries. READ MORE

  5. 18. New pharmacological aspects of melatonin

    Author : Lena G. E. Mårtensson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Melatonin is a hormone that takes part in the regulation of biological rhythms. It is produced in the pineal gland and is stimulated by darkness and inhibited by exposure to light. READ MORE

  6. 19. The role of nitric oxide in the gastrointestinal tract

    Author : Linda Gillberg; Per Hellström; Karolinska Institutet; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Nitric oxide (NO) is an important second messenger involved in the regulation of a multitude of mechanisms in the body, such as neurotransmission, smooth muscle contractility, host defense and immune regulation. Inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), are chronic disorders affecting the gastrointestinal (GI) tract with unknown etiology. READ MORE

  7. 20. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle

    Author : Asad Zeidan; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; SM22a; ERK1 2; caveolae; stretch; Smooth muscle; differentiation;

    Abstract : Vascular smooth muscle can adapt to increased intraluminal pressure by remodelling and hypertrophy, as seen in hypertension. The molecular mechanisms responsible for this are still incompletely characterized. READ MORE
