    Notes: Summary 1. The125I-labeled S-100 specific binding to a Triton X-100 (TX-100) extract of synaptosomal particulate fractions (SYN) was investigated. 2. The results indicate that (a) S-100 binding to the TX-100 extract is partially irreversible after a critical association time at 37°C, while it is fully reversible after any association time at 4°C; (b) trypsin and phospholipase C partially reverse the S-100 binding, while phospholipase D enhances the interaction to some extent, in a dose-dependent way; (c) EDTA and high concentrations of NaC1 or KC1 are more efficient as inhibitors of the S-100 binding to the TX-100 extract than as125I-labeled S-100 dissociating agents, in analogy with previous observations with SYN; and (d) two main populations of solubilized S-100 binding sites can be evidenced by gel filtration and sucrose gradient centrifugation when low amounts of the TX-100 extract are processed and/or low S-100 concentrations are used, while two additional molecular species are separated when greater amounts of either factors are tested. 3. These results suggest the possibility that S-100 may be involved in the regulation of some membrane activities.

    Immunocytochemical localization of S-100 protein binding sites in synaptosomal fractions and subfractions (1982)

    Notes: Summary 1. Immunocytochemical evidence is presented of the ultrastructural localization of binding sites for S-100 protein in synaptosomal fractions and subfractions. Synaptosomes or isolated synaptosomal subfractions were first incubated with S-100, then centrifuged to remove unbound S-100, and finally fixed before treatment with anti-S-100 antiserum, using the unlabeled antibody peroxidase-antiperoxidase (PAP) method. 2. When intact synaptosomes were used, the immunoreaction product was localized to the postsynaptic density including the postsynaptic membrane. In some reactive synaptosomes, the presynaptic membrane was labeled as well, in the region of synaptic contact. No reaction deposit was found in the synaptic cleft or on intrasynaptosomal structures. Divalent cations (Ca2+ and Mg2+) were essential for S-100 to interact with synaptosomes. Of the synaptosomal subfractions tested, i.e., synaptic vesicles and intraterminal mitochondria, only synaptic vesicles showed immunoreactivity when treated with S-100 and anti-S-100 antiserum as described above. 3. The S-100 immunoreactivity in synaptic structures documented in this report parallels the distribution of the high-affinity binding sites for radiolabeled S-100 in synaptosomal fractions and subfractions.

    Melting and crystallization behaviour of random copolymers from adipic acid, trans-3-hexenedioic acid and 1,16-hexadecanediol (1980)

    Notes: Copolyesters derived from adipic acid, trans-3-hexenedioic acid and 1,16-hexadecanediol were prepared and investigated by means of X-ray diffraction and DSC techniques. From the X-ray results an isomorphous replacement of the saturated and unsaturated diacid units has been suggested. The equilibrium melting temperature Tm0 and the heat of fusion ΔHf were slightly dependent on the copolyester composition. The crystallization process was analyzed by means of Hoffman's kinetic crystallization theory for a lamellar type crystal growth. The values of the free energy of formation of a nucleus of critical dimensions φ* and the free energy of folding σe were found to decrease regularly with increasing amount of double bonds, varying from 110 to 83 kJ/mol for Δφ* and from 171 to 127 erg/cm2 for σe. This effect has been interpreted on the basis of an increase of chain flexibility owing to the presence of the trans double bonds.

    Synthesis and physico-mechanical properties of aliphatic polyesteramides (1982)

    Notes: Random polyesteramides with different chemical compositions and block polyesteramides have been prepared by a two-step polycondensation method from adipolyl dichloride, 1,10-decandiol, and 1,6-diaminohexane. A sample of alternating microstructure has been synthesized by melt polycondensation of 1,10-decandiol and preformed bisesteramides. The thermal and viscoelastic behavior has been investigated and related to the chemical composition and chain microstructure. The random copolymers exhibit one transition in the crystalline phase, whereas two transitions are shown by the block copolymers. The viscoelastic behavior suggests that in the amorphous component a partial microsegregation of phase occurs, generating an intermediate structure between a monophasic and a biphasic amorphous system.

    Notes: The infrared and Raman spectra of ethylenediamine and its deuterated derivatives have been studied in both the liquid and solid states. An assignment of the fundamental vibrational modes for the four molecules is proposed assuming for the liquids a gauche configuration (C2 symmetry); the assignment is based on depolarization values, isotopic shifts and classic group frequencies correlations.
