(15) This represented a 90% decrease in the mean rate of flow within the IMA-harvested sterna versus a stable flow rate for the unharvested sides.
(16) During experimental investigations in corpse sterna during tension load the different refixing methods were compared.
(17) This contrasts with incubations of sterna in the absence of the xyloside, in which less than 5% of the sulphate incorporated could be recovered from the medium.
(18) Primary chondrocytes from whole chick embryo sterna can be maintained in suspension culture stabilized with agarose for extended periods of time.
(19) Total RNA extracted from chick embryonic sterna was translated in a cell-free system using rabbit reticulocyte lysate.
(20) This hypothesis was investigated using two-dimensional, all-cartilage, plane-stress finite-element models of the three basic shapes of human sterna that were identified by Ashley.

(7) The 66 patients were subdivided into four groups according to the type of conduit harvested (single left internal thoracic artery or saphenous vein) and the type of material used for the sternal closure (steel wires or nylon yarns).
(8) In two cases the author has successfully carried out retro-sternal transposition "of necessity", at 6 months and 4 years after coloesophagoplasty in the pre-thoracic variant.
(9) The present investigation examines metamorphosis in the sternal ribs of American blacks (N = 53 males, N = 20 females), and tests the application of age estimation standards developed by the authors from a white population.
(10) The average hospital stay was 24 days after sternal incision and drainage (range, nine to 85 days).
(11) This thin flap, usually extending from the hyoid bone to the sternal notch at the central part of the anterior neck, provides a skin island of about 4 by 8 cm.
