| the use of balloon-tipped electrodes for permanent cardiac pacing. | a new balloon-tipped ventricular endocardial electrode for permanent artificial cardiac pacing is described. following transvenous insertion of the electrode to the right ventricular apex, the distal balloon is inflated with contrast material in order to wedge the electrode tip between or beneath trabeculae and prevent displacement. fifty-nine electrodes were implanted, including a second generation type incorporating a wedge tip as well as the balloon. the incidence of displacement was 17% with ... | 2001 | 95219 |
| a theoretical model for adhesion between cells mediated by multivalent ligands. | a theoretical model is developed for cell-to-cell binding by bivalent ligands that can bind to mobile receptors on the cell surfaces. monovalent inhibitors that can bind either to receptors or ligands are also included. for symmetrical ligands, that is, ligands in which both binding sites are the same, it is shown that crosslinking of receptors on each cell will interfere with intercellular bridge formation. at equilibrium, such interference is not drastic, but if the crosslinks can form before ... | 2001 | 95173 |
| [structural and immunochemical studies of carp (cyprinus carpio l.) immunoglobulin. v. tryptic fragments of carp (cyprinus carpio l.) immunoglobulin m]. | carp igm, isolated from normal serum is more sensitive to trypsinization compared to a human myeloma protein igmgo. under the same conditions (treatment with trypsin at 56 degrees c for 30 min) carp igm was degraded to small, mostly dialysable peptides to a larger extent than igmgo. in both cases the fragmentation resulted in immunoelectrophoretically pure fab mu and fc mu fragments. the fab mu fragments of human igm (yield: 20% of used igm material) had a molecular weight of 54,000, the fc mu f ... | 1979 | 95144 |

| [modified method of obtaining washings of the large intestine for determining coproantibodies and immunoglobulins in the dynamics of acute dysentery]. | the study of the washings obtained during rectoscopy from the mucous membrane of the large intestine with the use of a special attachment for a rectoscope revealed that this method had a number of advantages when compared with the study of coprofiltrates; in particular, this method allowed to obtain pure secretions of the mucous membrane free of fecal admixtures and to concentrate the gamma globulin fraction. the study of the dynamics of coproantibody secretion in acute dysentery revealed that c ... | 1979 | 92867 |
| instability of cerebral blood-flow in insulin-dependent diabetics. | cerebral blood-flow (cbf) was measured in 23 insulin-dependent diabetics before and 2--3 h after insulin/breakfast. in 10 of these patients cbf changed significantly during the day, with a significant fall in 9. in 3 patients who had the greatest falls in cbf there was a concomitant sensation of an impending faint. thus cbf is unstable in insulin-dependent diabetics in contrast to control subjects in who there is little or no variation. sudden falls in cbf in insulin-dependent diabetics may expl ... | 2001 | 92619 |

| intrathecal igg synthesis in multiple sclerosis and other neurological diseases: a comparative evaluation by igg-index and isoelectric focusing. | intrathecal igg synthesis has been investigated by determining the igg index and by isoelectric focusing in 30 cases of definite multiple sclerosis, in 15 cases of probable multiple sclerosis and in 128 patients affected by other neurological diseases. the blood-brain barrier function was evaluated at the same time by serum albumin/csf albumin quotient and isoelectric focusing. the igg index was found elevated in 73.3% of definite multiple sclerosis patients, while oligoclonal igg bands occurred ... | 2001 | 92550 |
| right/left differences of median nerve evoked scalp potentials in multiple sclerosis. | scalp potentials evoked by electrical stimulation of the median nerve at the wrist were examined in multiple sclerosis patients and healthy controls. the latencies of the first negative peak (about 18 ms latency) of the response to right and to left-sided stimulation were compared. forty-eight of 60 measured latency differences in 15 suspected or certain ms patients were more than 3 standard deviations beyond the average difference in controls (arbitrary norm limit), whereas none of the 56 resul ... | 2001 | 92533 |
| immunoelectron microscopic localization of herpes simplex virus antigens in infected cells using the unlabeled antibody-enzyme method. | subcellular localization of viral antigens was demonstrated during viral morphogenesis using herpes simplex virus type 1 (hsv-1) infected monolayers of rabbit cornea cells. the localization was done by immunoelectron microscopy employing the peroxidase-antiperoxidase (pap) immunocytochemical technique and the postembedding staining method. the localization of viral antigens was followed at time intervals during infection from 2 to 19 hr. after exposure of sections to either polyspecific antibodi ... | 1979 | 92500 |
| nonspecific light loss and intrinsic dna variation problems associated with feulgen dna cytophotometry. | nonspecific light loss by the cell-wall-plus-cytoplasm (cwc) can cause a 50% increase in feulgen absorption units in peanut root-tip nuclei as determined by scanning at 450 nm, whereas this phenomenon is not evident with chicken erythrocytes. a two wavelength scanning method of subtracting nonspecific 450 nm absorption from 550 nm feulgen absorption values eliminated the nonspecific light loss in cwc, however, the two wavelength scanning method is time consuming and somewhat impractical with a r ... | 1979 | 92496 |
