  1. 6. Effects of increased UV-B radiation on the lichen Cladonia arbuscula spp. mitis: UV-absorbing pigments and DNA damage

    Författare :Roberta Buffoni Hall; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; kemotaxonomi. Växters fysiologi inte kärlväxter .; Systematisk botanik; taxonomi; morfologi;

    Sammanfattning : Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. LÄS MER

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

    Författare :Fredrik Einarsson; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 8. Peripheral Hypoglycaemic Neuropathy in Type 1 Diabetic Rats : Morphologic and Metabolic Studies

    Författare :Reza Jamali; Simin Mohseni; Claes Hildebrand; Håkan Aldskugius; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes Mellitu; Hypoglycaemia; Neuropathy; Morphology; Microdialysis; Glucose level; Neurobiology; Neurobiologi;

    Sammanfattning : Hyperglycaemia caused by insulin deficiency is believed to play a major role in the de-velopment of neuropathy in diabetic patients. The clinical and pathological features of diabetic neuropathy vary considerably, although sensory and autonomic dysfunctions are the most common characteristics. LÄS MER

  5. 9. Exercise-induced muscle soreness : a qualitative and quantitative study of human muscle morphology and function

    Författare :Jan Fridén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; exercise; exertion; eccentric contractions; muscles; muscle strength; muscle soreness; fibre types; myofibrils; muscle proteins; histocy to chemistry; ultrastructure; stereology;

    Sammanfattning : Exercise-induced muscle soreness is characterized by stiffness, tenderness and pain during active movements and weakness of the affected musculature the days after unusually or particularly heavy work. The most pronounced subjective symptoms do not arise immediately but rather between a couple of hours to some days after the exercise (a delayed-onset of muscle soreness), the intensity of pain is greatest about 48 hours after the work.

  7. 10. Sceletal muscle characteristics and physical activity patterns in COPD

    Författare :Gabriella Eliason; Karin Phiel Aulin; Lundberg Ingrid; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; muscle morphology; muscle fibre distribution; muscle capillarization; physical activity; von Hippel-Lindau protein; exercise capacity; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Sports; Idrott; Idrottsvetenskap; Sports Science;

    Sammanfattning : Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. Besides abnormities within the respiratory system COPD is also associated with effects outside the lungs, so called systemic effects. LÄS MER
