    Valence bond corrected single reference coupled cluster approach (1994)

    Notes: Summary The recently proposed valence bond (VB) corrected single reference (SR) coupled cluster method with singly and doubly excited cluster components (CCSD) [Paldus and Planelles, Theor Chim Acta 89, 13–31 (1994)] is tested using a number of simple yet typical Pariser-Parr-Pople (PPP) π-electron model systems, including both cyclic and linear polyenes. The cluster analysis of various approximate VB wave functions, obtained with the PPP-VB approach [Li and Paldus, J Mol Struct (Theochem) 229, 249 (1991)], is carried out and the resulting three- and four-body connected cluster components are employed in the VB corrected CCSD method. The cluster structure and the correlation energies obtained are compared to full configuration interaction (FCI) or full VB (FVB) results, representing the exact solutions for these models, and the performance and potential of the CCSD-VB approach are discussed.

    Notes: Summary The valence bond (VB) corrected single reference (SR) coupled cluster (CC) method [J. Paldus and J. Planelles, Theor. Chim. Acta 89, 13–31 (1994)] with Singly and Doubly excited cluster components (CCSD-VB) is applied to simple Parise-Parr-Pople (PPP) model systems that are capable of simulating chemical bond breaking or formation. Dissociation into both closed and open shell type subsystems is considered. The 3- and 4-body connected cluster components are first determined by cluster analyzing simple PPP-VB wave functions [X. Li and J. Paldus, J. Mol. Structure (Theochem) 229, 249 (1991)] involving only covalent-type structures, and are subsequently employed in the CCSD-VB approach. The results are compared with the full configuration interaction (FCI) or full valence bond (FVB) solutions, representing the exact result for these models, and the potential of the CCSD-VB approach is discussed.

    {beta}-Adrenergic Receptor-Mediated Cardiac Contractility Is Inhibited via Vasopressin Type 1A-Receptor-Dependent Signaling [Molecular Cardiology] (2014)
    American Heart Association (AHA)
    Details
    Publication Date: 2014-11-11
    Description: Background— Enhanced arginine vasopressin levels are associated with increased mortality during end-stage human heart failure, and cardiac arginine vasopressin type 1A receptor (V1AR) expression becomes increased. Additionally, mice with cardiac-restricted V1AR overexpression develop cardiomyopathy and decreased β-adrenergic receptor (βAR) responsiveness. This led us to hypothesize that V1AR signaling regulates βAR responsiveness and in doing so contributes to development of heart failure. Methods and Results— Transaortic constriction resulted in decreased cardiac function and βAR density and increased cardiac V1AR expression, effects reversed by a V1AR-selective antagonist. Molecularly, V1AR stimulation led to decreased βAR ligand affinity, as well as βAR-induced Ca 2+ mobilization and cAMP generation in isolated adult cardiomyocytes, effects recapitulated via ex vivo Langendorff analysis. V1AR-mediated regulation of βAR responsiveness was demonstrated to occur in a previously unrecognized Gq protein–independent/G protein receptor kinase–dependent manner. Conclusions— This newly discovered relationship between cardiac V1AR and βAR may be informative for the treatment of patients with acute decompensated heart failure and elevated arginine vasopressin.
