  1. 21. Vitamin A and Osteoporosis : Experimental and Clinical Studies

    Författare :Sara Johansson; Håkan Melhus; Andreas Kindmark; Monica Lind; Göran Toss; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; vitamin A; bone; osteoporosis; Invärtesmedicin; Internal medicine; Invärtesmedicin;

    Sammanfattning : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. LÄS MER

  2. 22. Tartrate resistant acid phosphatase in the immune and nervous system : distribution and pathophysiological implications

    Författare :Pernilla Lång; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tartrate resistant acid phosphatase (TRAP) belongs to the family of purple acid phosphatases (PAP). It is a glycoprotein synthesized as a monomer with low enzyme activity containing a redox active diiron centre in the active site. Post-translational proteolytic processing of this monomer into a dimeric protein increases the enzyme activity. LÄS MER

  3. 23. Experimental studies on the effects of insulin-like growth factor I and glucocorticoids on bone metabolism

    Författare :Kenneth B. Jonsson; Uppsala universitet; []
    Nyckelord :Medical sciences; Bone; bone resorption; glucocorticoids; insulin-like growth factor I; osteoblasts; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Osteoporosis is a major cause of disability among patients that are dependent on glucocorticoids in the treatment of inflammatory disease. The pathogenesis behind this side effect is complex, involving dysregulation of hormonal systems and direct effects on bone cells. LÄS MER

  4. 24. Organochlorines and bone : Effects of organochlorines on bone tissue morphology, composition and strength

    Författare :Monica Lind; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; Ekotoxikologi;

    Sammanfattning : From results presented during the last decade, it is obvious that the skeleton is a targetorgan for a number of persistent organochlorines. So far, however, little attention hasbeen paid to this subject. LÄS MER

  5. 25. Diffusion Tensor Imaging and Tractography of the Visual Pathways

    Författare :Ylva Lilja; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion tensor imaging; Visual pathways; Tractography; Temporal lobe resection; Pituitary adenomas;

    Sammanfattning : The visual pathways are essential for human vision, stretching from the retinas of the eyes, via the anterior visual pathways and the optic radiations, to the primary visual cortex in the occipital lobe. Injury to these structures will lead to visual impairment – from small deficits to blindness. LÄS MER
