Question: Abstract: Summary. We consider the problem of comparing complex hierarchical models in which the number of parameters is not clearly defined. Using an information theoretic argument we derive a measure pD for the effective number of parameters in a model as the difference between the posterior mean of the deviance and the deviance at the posterior means of the parameters of interest. In general pD approximately corresponds to the trace of the product of Fisher's information and the posterior covariance, which in normal models is the trace of the ‘hat’ matrix projecting observations onto fitted values. Its properties in exponential families are explored. The posterior mean deviance is suggested as a Bayesian measure of fit or adequacy, and the contributions of individual observations to the fit and complexity can give rise to a diagnostic plot of deviance residuals against leverages. Adding pD to the posterior mean deviance gives a deviance information criterion for comparing models, which is related to other information criteria and has an approximate decision theoretic justification. The procedure is illustrated in some examples, and comparisons are drawn with alternative Bayesian and classical proposals. Throughout it is emphasized that the quantities required are trivial to compute in a Markov chain Monte Carlo analysis.. Title: Bayesian measures of model complexity and fit

Question: Abstract: beta-adrenergic receptors (beta-ARs), prototypic G-protein-coupled receptors (GPCRs), play a critical role in regulating numerous physiological processes. The GPCR kinases (GRKs) curtail G-protein signaling and target receptors for internalization. Nitric oxide (NO) and/or S-nitrosothiols (SNOs) can prevent the loss of beta-AR signaling in vivo, but the molecular details are unknown. Here we show in mice that SNOs increase beta-AR expression and prevent agonist-stimulated receptor downregulation; and in cells, SNOs decrease GRK2-mediated beta-AR phosphorylation and subsequent recruitment of beta-arrestin to the receptor, resulting in the attenuation of receptor desensitization and internalization. In both cells and tissues, GRK2 is S-nitrosylated by SNOs as well as by NO synthases, and GRK2 S-nitrosylation increases following stimulation of multiple GPCRs with agonists. Cys340 of GRK2 is identified as a principal locus of inhibition by S-nitrosylation. Our studies thus reveal a central molecular mechanism through which GPCR signaling is regulated..

Answer: yes


Question: Abstract: We investigated the role of hydrogen sulphide (H(2)S) in intracellular pH (pH(i)) regulation in vascular smooth muscle cells and its contribution on vasodilation. NaHS, a H(2)S donor, decreased pH(i) in a concentration-dependent manner ranging from 10 microM to 1mM. Neither inhibition of the Na(+)/H(+) exchanger with 5-(N-ethyl-N-isopropyl) amiloride, (EIPA, 10 microM), nor plasmalemmal Ca(2+)-ATPase with CdCl(2) (20nM) alters the effect of NaHS on pH(i). Blockade of the Cl(-)/HCO3- exchanger with 4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid (DIDS) significantly attenuated the pH(i) lowering effect of NaHS. Moreover, NaHS significantly increased the activity of Cl(-)/HCO3- exchanger when measured with NH(4)Cl prepulse method. DIDS attenuated the vasorelaxation induced by NaHS whereas EIPA and CdCl(2) did not cause any change. In conclusion, H(2)S induced intracellular acidification via activation of Cl(-)/HCO3- exchanger, which is, at least partially, responsible for H(2)S-mediated vasorelaxation..
