Utilizing the fluorescence-activated cell sorter (FACS) and washed murine antibody-antigen complexes formed in antibody excess, we have demonstrated the presence of the Fc receptor on the surface of a distinct subpopulation of murine T lymphocytes. No differences in intensity of labeling with the complexes was observed when the Fc+ T lymphocytes were compared with Fc+ B lymphocytes. The majorit...
Spleen cells of dinitrophenyl keyhole limpet hemocyanin (DNPKLH) primed and boosted mice produced a nonantigen-specific helper factor upon in vitro challenge with DNPKLH. This helper factor displays all of the biological characteristics so far described for TRF produced by allogeneic or Concanavalin A stimulation of mouse spleen cells. It restores the primary anti-SRBC response in nude spleen c...
With the increased discussion over issues surrounding genetic manipulation of cells, neurotissue regeneration, and potential therapeutic models designed to alter cell growth and lines, a timely article by Muldoon et al appears in this issue of the American Journal of Neuroradiology (page 217). Questions basic to the future of neuroradiology and its role in the cellular treatment and imaging of ...
IntroductIon Microneurosurgery made its debut in the early 1960s. It became popular in the medical field and became a primary operation method in neurosurgery since it improved the efficacy of neurosurgery with a less surgery‐related injury. Over the past five decades, the accumulation of experience of microsurgery, improvement of microsurgery techniques, refined micro‐instruments, and advanced...
In the present investigation, effect and role of plasma gas flow rate on formation microstructure during arc welding Ti6Al4V titanium alloy were studied using microscopic observation, energy dispersive spectroscopic analysis, tensile tests microhardness measurements. Plasma influences pressure, constriction, stability. The transformation from conduction mode to keyhole causes severe changes mic...
in order to examine the ecological conditions and characteristics of fraxinus excelsior l. in the northern forests of iran 6 main areas as well as some miscellaneous ones , have been selected in the region respectively in : lomir2, shafaroud , park - e-noor , ahlam , alandan and noor.
15 Virtual globes allow geo-referencing and visualisation of diverse geologic datasets. A 16 vertical axis paleomagnetic rotation study in the Southern Pyrenees, Spain, is used to 17 illustrate the potential of virtual globes for representing paleomagnetic data. A macro 18 enabled workbook that we call P2K, allows KML files to be generated from 19 conventional paleomagnetic datasets. Cones and ...
Evaluation of efficacy and safety of anterior corpus callosotomy with keyhole in refractory seizures
PURPOSE This study was conducted to evaluate the efficacy and safety of anterior corpus callosotomy with a keyhole approach on refractory seizures and to evaluate this procedure for drop attacks (DAs) and generalized tonic-clonic seizures (GTCSs). METHODS All refractory seizure patients underwent anterior corpus callosotomy (n=31) without other epilepsy surgery. Seizure response and procedure...
Treatment of adult mice with dinitrophenyl (DNP) bound to isogeneic serum resulted in a specific inability to respond to DNP after challenge with DNP-keyhole limpet hemocyanin (KLH) in complete Freund's adjuvant. The unresponsiveness to the hapten had all the characteristics of immunologic tolerance: it had a definite induction time; it was transient but could be maintained by additional inject...
