    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.

    Vibrational spectra and assignments of ethylene-diamine and its deuterated derivatives (1983)

    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.

    Description: Author(s): Bruno Bellomo, Gian Luca Giorgi, Fernando Galve, Rosario Lo Franco, Giuseppe Compagno, and Roberta Zambrini The distance between a quantum state and its closest state not having a certain property has been used to quantify the amount of correlations corresponding to that property. This approach allows a unified view of the various kinds of correlations present in a quantum system. In particular, using rel... [Phys. Rev. A 85, 032104] Published Mon Mar 05, 2012

    The bromodomain protein Brd4 insulates chromatin from DNA damage signalling (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-06-04
    Description: DNA damage activates a signalling network that blocks cell-cycle progression, recruits DNA repair factors and/or triggers senescence or programmed cell death. Alterations in chromatin structure are implicated in the initiation and propagation of the DNA damage response. Here we further investigate the role of chromatin structure in the DNA damage response by monitoring ionizing-radiation-induced signalling and response events with a high-content multiplex RNA-mediated interference screen of chromatin-modifying and -interacting genes. We discover that an isoform of Brd4, a bromodomain and extra-terminal (BET) family member, functions as an endogenous inhibitor of DNA damage response signalling by recruiting the condensin II chromatin remodelling complex to acetylated histones through bromodomain interactions. Loss of this isoform results in relaxed chromatin structure, rapid cell-cycle checkpoint recovery and enhanced survival after irradiation, whereas functional gain of this isoform compacted chromatin, attenuated DNA damage response signalling and enhanced radiation-induced lethality. These data implicate Brd4, previously known for its role in transcriptional control, as an insulator of chromatin that can modulate the signalling response to DNA damage.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3683358/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3683358/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Floyd, Scott R -- Pacold, Michael E -- Huang, Qiuying -- Clarke, Scott M -- Lam, Fred C -- Cannell, Ian G -- Bryson, Bryan D -- Rameseder, Jonathan -- Lee, Michael J -- Blake, Emily J -- Fydrych, Anna -- Ho, Richard -- Greenberger, Benjamin A -- Chen, Grace C -- Maffa, Amanda -- Del Rosario, Amanda M -- Root, David E -- Carpenter, Anne E -- Hahn, William C -- Sabatini, David M -- Chen, Clark C -- White, Forest M -- Bradner, James E -- Yaffe, Michael B -- 1-U54-CA112967-04/CA/NCI NIH HHS/ -- ES-002109/ES/NIEHS NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- P30 ES002109/ES/NIEHS NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- R01 ES015339/ES/NIEHS NIH HHS/ -- R01-ES15339/ES/NIEHS NIH HHS/ -- R21 CA109661/CA/NCI NIH HHS/ -- R21 NS063917/NS/NINDS NIH HHS/ -- R21-NS063917/NS/NINDS NIH HHS/ -- U54 CA112967/CA/NCI NIH HHS/ -- England -- Nature. 2013 Jun 13;498(7453):246-50. doi: 10.1038/nature12147.
