    • In our contribution to the INPC98 conference we reported on the experimental investigation of high spin collective states in medium and heavy mass N≈Z nuclei at LNL. The main purpose is to set light on the role of the proton-neutron interaction in the collective behavior of the nucleus. In medium mass N=Z nuclei, in contrast with the stable nuclei, valence protons and neutrons occupy the same orbitals and one may expect a reinforcement of neutron-proton T=0 (np) pairing correlations[1]. In this interesting subject, the medium mass N=Z=36 72Kr has been studied and completely reported in [2]. In this proceedings we will concentrate in unpublished results concerning the onset of collectivity on nearly spherical nuclei in the 100Sn region. In nuclei with Z=50 and Z=49 dipole bands have been found indicating the presence of "Magnetic Rotation" [3].

  • Localization of choline acetyltransferase in rat peripheral sympathetic neurons and its coexistence with nitric oxide synthase and neuropeptides
  • 1995
  • Ingår i: Proceedings of the National Academy of Sciences of the United States of America. - : Proceedings of the National Academy of Sciences. - 0027-8424. ; 92:25, s. 11819-11823

    • Indirect immunofluorescence methods using a mouse monoclonal antibody raised to rat choline acetyltransferase (ChAT) revealed dense networks of ChAT-immunoreactive fibers in the superior cervical ganglion, the stellate ganglion, and the celiac superior mesenteric ganglion of the rat. Numerous and single ChAT-immunoreactive cell bodies were observed in the stellate and superior cervical ganglia, respectively. The majority of ChAT-immunoreactive fibers in the stellate and superior cervical ganglia were nitric oxide synthase (NOS) positive. Some ChAT-immunoreactive fibers contained enkephalin-like immunoreactivity. Virtually all ChAT-positive cell bodies in the stellate ganglion were vasoactive intestinal polypeptide (VIP)-positive, and some were calcitonin gene-related peptide (CGRP)-positive. After transection of the cervical sympathetic trunk almost all ChAT- and NOS-positive fibers and most enkephalin- and CGRP-positive fibers disappeared in the superior cervical ganglion. The results suggest that most preganglionic fibers are cholinergic and that the majority of these in addition can release nitric oxide, some enkephalin, and a few CGRP. Acetylcholine, VIP, and CGRP are coexisting messenger molecules in some postganglionic sympathetic neurons.
