mechanisms of branchial cartilage growth in astatotilapia elegans (teleostei: cichlidae).the growth of the cartilaginous infrapharyngobranchial ii (part of the upper pharyngeal jaws) in the cichlid fish astatotilapia elegans was investigated in four successive early postembryonic stages. total cell number, individual cell volumes, total cell, total matrix and total cartilage volume were accurately measured or calculated. the share of cell and matrix volume increase in the overall growth was calculated for each of the transitions. matrix volume increase accounted for almost 60% of th ...20113225217
pericardial flap to minimize internal mammary artery anastomotic tension.a technique is described that decreases tension on the left internal mammary artery anastomosis in patients whose lungs have herniated across the midline.20113155343
physiologic variations of the internal jugular vein surface, role of the omohyoid muscle, a preliminary echographic study.the action of the omohyoid muscle on the hemodynamics of the internal jugular vein is controversial. for some authors, contraction of this muscle, by tightening the cervical fascia, promotes jugular venous return. for others, contraction of this muscle compresses the jugular vein in its cervical path. with this latter point in mind, the hemodynamics of the internal jugular vein have been studied in its cervical path by echography in 10 healthy volunteers. one hundred twenty measurements of the v ...20113135615
the effect of hemodialysis on whole blood, plasma and erythrocyte viscosity.the effect of hemodialysis (hd) on blood viscosity has not been adequately investigated. we studied blood viscosity during hd employing coneplate viscometry. ten patients with end-stage renal disease were studied before and immediately after hd. to dissect the possible effects of hd on plasma and red blood cell (rbc) determinants, we measured whole blood, plasma, and reconstituted erythrocyte viscosities. the latter consisted of rbc's suspended in a buffered saline solution (ph = 7.4 units). in ...20113192313

[critical assessment of light reflection rheography. comparative studies of phlebodynamometry using invasive measurement of venous pressure, photoplethysmography and light reflection rheography].in chronic venous insufficiency, phlebodynamometry by invasive venous-pressure measurement demonstrates a reduced pressure drop and an accelerated pressure rise, resulting from the action of the ankle-joint-calf muscle "pump". on the other hand, light-reflexion rheography and photoplethysmography can measure only the duration of the refilling period. simultaneous measurements were made on 47 legs after phlebography (normal: 8; side-arm varicosities: 17; long-saphenous insufficiency: 15; postthro ...20124064935
the role of brain peptides in neuroimmunomodulation.since neuroimmunomodulation is brought about in part, at least, by secretion of pituitary hormones involved in stress and immune responses, we review briefly the hypothalamic control of the release of acth, growth hormone, and prolactin. the release of acth is controlled particularly by corticotropin-releasing factor (crf), but vasopressin has intrinsic releasing activity and potentiates the action of crf at both hypothalamic and pituitary levels. oxytocin may even potentiate the action of crf, ...20123474967
