  2. 11. Auxiliary Cells for the Vascularization and Function of Endogenous and Transplanted Islets of Langerhans

    Author : Liza Grapensparr; Per-Ola Carlsson; Leif Jansson; Mia Phillipson; Aileen King; Uppsala universitet; []
    Keywords : Islets of Langerhans; beta cells; diabetes; transplantation; vascularization; Schwann cells; endothelial progenitor cells; neural crest stem cells; Medicinsk vetenskap; Medical Science;

    Abstract : Type 1 diabetes develops through the progressive destruction of the insulin-producing beta-cells. Regeneration or replacement of beta-cells is therefore needed to restore normal glucose homeostasis. Presently, normoglycemia can be achieved by the transplantation of whole pancreas or isolated islets of Langerhans. READ MORE

  4. 12. Studies on Peripheral Nerve Regeneration: Microdispensing, Neurite Guidance and Galectins

    Author : Per Gustavsson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; cytochemistry; Histology; Schwann cells; sciatic nerve; dorsal root ganglia; DRG; neurite guidance; galectins; inkjet; microdispensing; peripheral nervous system; nerve regeneration; Animal physiology; Djurfysiologi; Biotechnology; Bioteknik;

    Abstract : The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. READ MORE

  5. 13. Neuromuscular injuries and pharyngeal dysfunction in snorers and sleep apnea patients : a study on pathological changes in the human soft palate and its relationship with swallowing dysfunction

    Author : Farhan Shah; Per Stål; Sture Forsgren; Diana Berggren; Eva Svanborg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Axons; BDNF; desmin; dystrophin; obstructive sleep apnea; OSA; pharyngeal function; muscle; myopathy; neuropathy; Schwann cells; swallowing dysfunction; upper airway; Medical Cell Biology; medicinsk cellbiologi; oto-rhino-laryngologi; Oto-Rhino-Laryngology; patologi; Pathology; molecular cell biology; molekylär cellbiologi;

    Abstract : Obstructive sleep apnea (OSA) is a prevalent progressive sleep disorder with serious negative health consequences. Although several risk factors such as obesity can make an individual vulnerable to develop OSA, the pathophysiological mechanism for the collapse of the upper airway is unclear. READ MORE

  6. 14. Vibration-induced neuropathy in the hand

    Author : Trygve Strömberg; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; vibrotactile sense.; vibration; Schwann cells; Raynaud’s phenomenon; peripheral neuropathy; pathology; neurone; nerve fibres; muscular weakness; hand; Carpal tunnel syndrome; cold intolerance; Kirurgi; ortopedi; traumatologi; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : The aim of this study was to investigate clinical, pathophysiological and structural aspects of vibration-induced peripheral neuropathy since work with hand-held vibrating tools may lead to progressive neurological and vascular hand symptoms. Symptomatic vibration-exposed men were examined clinically and by neurography, tactilometry, and vibrometry and by measurement of temperature perception thresholds. READ MORE

  7. 15. The role of the MAP- and SAP- kinase pathways in the survival, proliferation and death of Schwann cells of the injured sciatic nerve

    Author : Lisa Mårtensson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns alterations in signal transduction in Schwann cells as a response to nerve injury as well as their survival, proliferation and death. Enzymes and transcription factors belonging to the mitogen activated protein kinase (MAPK) and the stress activated protein kinase (SAPK) pathways were studied. READ MORE
