1. 1. Human muscle spindles : complex morphology and structural organisation

   Författare :Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
   Nyckelord :human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

   Sammanfattning : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. LÄS MER

3. 2. Cross transfer effects after unilateral muscle overuse : an experimental animal study about alterations in the morphology and the tachykinin system of muscles

   Författare :Yafeng Song; Per Stål; Sture Forsgren; Fawzi Kadi; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Triceps surae; overuse; contralateral; muscle; muscle fiber; MyHC; capillary; tachykinin; substance P; NK-1R; inflammation; anatomi; Human Anatomy;

   Sammanfattning : Unilateral exercise can produce certain contralateral strength effects. Deleterious events can be cross-transferred as well, as illustrated by a strict symmetry in some chronic inflammatory diseases. LÄS MER

4. 3. Adaptability of skeletal muscle to hormone treatment in relation to gender and aging

   Författare :Fushun Yu; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :skinned muscle fiber; gender; aging; steroid hormone; V0 electrophoresis; MyHC; MyLC; enzymehistochemistry; hyperthyroid rat; thyroid hormone receptor TR deficient TR[alpha]1 - -; TR[beta]- -; and TR[alpha]1- -[beta]- - mice;

   Sammanfattning : The aims of this study were to investigate the expression of myosin isoforms, muscle contractility at the cell level, and changes in these parameters in response to altered hormonal status in aging male and female rodents. In addition, by using mice lacking thyroid hormone receptors (TR[alpha]1 or TR[beta] or TR[alpha]1/[beta]) we tried to improve our understanding of the mechanisms by which thyroid hormone regulates the expression of specific MyHC isoforms via these different nuclear receptors.

5. 4. Extra- and intrafusal muscle fibre type compositions of the human masseter at young age. : In perspective of growth and functional maturation of the jaw-face motor system

   Författare :Catharina Österlund; Per-Olof Eriksson; Lars-Eric Thornell; Per Stål; Malin Ernberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; jaw; limb; human; muscle; morphology; fibre type; myosin heavy chain; muscle spindle; Morphology; Morfologi; anatomi; Human Anatomy;

   Sammanfattning : Muscles control body posture and movement by extrafusal and intrafusal (muscle spindle) fibres. The purpose of this thesis was to provide insight into the muscular basis for human jaw function at young age. LÄS MER

7. 5. Myosin myopathy. A new disease entity

   Författare :Homa Tajsharghi; Göteborgs universitet; []
   Nyckelord :Neuromuscular disorders; Myosin myopathy; Myosin heavy chain; Myosin storage myopathy;

   Sammanfattning : By the discovery and characterization of two familial myopathies caused by mutations in myosin heavy chaingenes, we introduce a new entity within the field of neuromuscular disorders: Myosin myopathyThe first myopathy affected a family in western Sweden. Previous linkage analysis had located the gene tochromosome 17p13. LÄS MER
