2. 1. MUSCLE TONE IMBALANCE IN HUMAN UPPER EXTREMITY An experimental study of muscle adaptation to altered tension

   Author : Fredrik Einarsson; Göteborgs universitet; []
   Keywords : muscle biopsy; freeze storage; upper extremity; shoulder; human muscle; sarcomere; stress-strain relationship; stress relaxation; stiffness; elasticity; mechanical testing; morphology; spasticity; obstetric brachial plexus palsy; rotator cuff tear; tendon transfer;

   Abstract : Aim: The aim of this thesis was to improve outcome after tendon transfer and rotator cuff surgery by investigating the impact on response to passive mechanical testing and change in structural characteristics associated with longstanding changes in the tension of skeletal muscle in the human upper extremities in vivo. Patients and methods: The investigational method was in vitro assessment of human upper extremity muscles. READ MORE

4. 2. Pathogenetic mechanisms in irritable bowel syndrome

   Author : Hans Törnblom; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Irritable bowel syndrome; functional gastrointestinal disorder; immunohistochemistry; full-thickness biopsy; enteric nervous system; autoantibody; gastroenteritis; risk factor;

   Abstract : Aims of the thesis: To study new pathogenetic mechanisms in IBS; to find out if IBS is a neuromuscular disease affecting the small bowel; to study humoral factors in gut dysmotility associated with visceral neuropathy; and to study the natural history of post-infectious gastro-intestinal (GI) symptoms and risk factors for their development. Material and methods: In studies I and II, full-thickness jejunum biopsies from patients with severe IBS were investigated with immunohistochemistry. READ MORE

5. 3. Human articular chondrocytes. Plasticity and differentiation potentials

   Author : Tommi Tallheden; Göteborgs universitet; []
   Keywords : autologous chondrocyte transplantation; dedifferentiation; redifferentiation; stem; cells;

   Abstract : Articular cartilage has no or very low ability for self-repair and untreated lesions may lead tothe development of Osteoarthritis (OA). One method, which has been proved to result in longterm repair of isolated lesions, is autologous chondrocyte transplantation (ACT). READ MORE

6. 4. Gastrointestinal motility and the role of gonadotropin-releasing hormone (GnRH)

   Author : Oskar Hammar; Internmedicin - epidemiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gonadotropin releasing hormone; intestinal motility; luteinizing hormone; Sjögrens syndrome; in vitro fertilization;

   Abstract : This thesis explores the relation between gonadotropin-releasing hormone (GnRH) and gastrointestinal symptoms and dysmotility. In primary Sjögren’s syndrome (pSS), a patient group with high levels of GnRH antibodies, associations between objective signs and symptoms of autonomic dysfunction (AD), impaired gastric emptying (IGE), and inflammatory and serological features were studied.

7. 5. Oral mucosa keratinocytes and their exosomes for epithelial tissue regeneration

   Author : Sebastian Sjöqvist; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Early tumors, including high grade dysplasia and intramucosal invasive cancer, of the esophagus can today be removed using endoscopic resection, often using a technique called endoscopic submucosal dissection (ESD). This treatment is better tolerated and has considerably less mortality and morbidity compared to conventional, more invasive surgery, which usually entails esophagectomy. READ MORE
