Disease relevance of Psoas Muscles


High impact information on Psoas Muscles

  • Using A-filaments prepared from rat psoas muscle we have now found it possible to induce clear fraying of these filaments into subfilaments, by exposure of the preparation to very low ionic strength before contrasting with uranyl acetate [6].
  • The changes in birefringence in the rigor to relax transition of single triton-extracted rabbit psoas muscle fibers have been investigated with quantitative polarized light techniques [7].
  • We found that dissipation of this gradient by the proton ionophores gramicidin, nigericin, and carbonyl cyanide p-trichloromethoxyphenylhydrazone caused a rapid transient tension in skinned rabbit psoas muscle fibers [8].
  • Aldose reductase from human psoas muscle. Affinity labeling of an active site lysine by pyridoxal 5'-phosphate and pyridoxal 5'-diphospho-5'-adenosine [9].
  • Involvement of lysosomal proteases in the effect of insulin on protein degradation was evaluated by measuring cathepsin D activity in psoas muscle homogenates. "Free" enzyme activity increased as a result of perfusion while addition of insulin maintained this activity at the unperfused level [10].

Associations of Psoas Muscles with chemical compounds

  • An iodoacetamide spin label was used to label selectively two-thirds of the sulfhydryl-1 groups in glycerinated rabbit psoas muscle [21].
  • The effects of a temperature jump (T-jump) from 5-7 degrees C to 26-33 degrees C were studied on tension and stiffness of glycerol-extracted fibers from rabbit psoas muscle in rigor and during maximal Ca2+ activation [22].
  • Skinned muscle fibres of rabbit psoas muscle in rigor were incubated in solutions containing approximately equal to 30 microM-Ca2+ ions and P3-1-(2-nitro)phenylethyladenosine-5'-triphosphate, 'caged ATP', an inert photolabile precursor of ATP [23].
  • Initiation of active contraction by photogeneration of adenosine-5'-triphosphate in rabbit psoas muscle fibres [23].
  • Addition of MgADP to the bath increased isometric tension over a wide range of [Ca(2+)] in skinned fibers from rabbit psoas muscle [24].
