Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

The restoration of coronary flow after transient ischemia immediately induces life-threatening ventricular tachyarrhythmias. Although most of these arrhythmias disappear spontaneously, some of them induce serious hemodynamic changes. This retrospective study investigates the efficacy of therapy with intracoronary verapamil to terminate reperfusion-induced ventricular tachyarrhythmias in patients with acute myocardial infarction (AMI).', 'Between February 1992 and February 2003, 390 patients with a diagnosis of AMI were enrolled into the study. All patients received mechanical revascularization therapy within 6 h of onset of symptoms, and 109 patients experienced reperfusion-induced tachyarrhythmias. A subset of these patients was treated with intracoronary verapamil (0.25 to 1.0 mg) to terminate the reperfusion-induced tachyarrhythmia. They were evaluated for immediate termination of the tachyarrhythmias, hemodynamic changes, resumption rates, and major complications. Thirty-one patients (28%) were treated with intracoronary verapamil for the immediate termination of reperfusion-induced ventricular tachyarrhythmias. These tachyarrhythmias included 6 premature ventricular contractions, 19 accelerated idioventricular rhythms, 3 ventricular tachycardias, 2 ventricular fibrillations (VFs), and 1 torsades de pointes. Intracoronary verapamil was effective in rapidly terminating all reperfusion-induced arrhythmias except for VFs. The side effects of treatment included temporary hypotension (two patients) and bradycardia (one patient), although all patients recovered spontaneously. No major complications were induced by the intracoronary use of verapamil, and no resumptions of arrhythmias were documented.

Increasing evidence suggests an epigenetic contribution to the pathogenesis of autoimmune diseases, including primary Sjögren's Syndrome (pSS). The aim of this study was to investigate the role of DNA methylation in pSS by analysing multiple tissues from patients and controls.", 'Genome-wide DNA methylation profiles were generated using HumanMethylation450K BeadChips for whole blood, CD19+ B cells and minor salivary gland biopsies. Gene expression was analysed in CD19+ B cells by RNA-sequencing. Analysis of genetic regulatory effects on DNA methylation at known pSS risk loci was performed.', 'We identified prominent hypomethylation of interferon (IFN)-regulated genes in whole blood and CD19+ B cells, including at the genes MX1, IFI44L and PARP9, replicating previous reports in pSS, as well as identifying a large number of novel associations. Enrichment for genomic overlap with histone marks for enhancer and promoter regions was observed. We showed for the first time that hypomethylation of IFN-regulated genes in pSS B cells was associated with their increased expression. In minor salivary gland biopsies we observed hypomethylation of the IFN-induced gene OAS2. Pathway and disease analysis resulted in enrichment of antigen presentation, IFN signalling and lymphoproliferative disorders. Evidence for genetic control of methylation levels at known pSS risk loci was observed.

Activation and signal transduction in the Nucleotide binding, leucine-rich repeat containing receptor (NLR) family needs to be tightly regulated in order to control the inflammatory response to exogenous and endogenous danger signals. Phosphorylation is a common cellular mechanism of regulation that has recently been shown to be important in signalling in another family of cytoplasmic pattern recognition receptors, the RIG-I like receptors. In addition, single nucleotide polymorphisms can alter receptor activity, potentially leading to dysfunction and/or a predisposition to inflammatory barrier diseases.', 'We have computationally analysed the N-terminus of NOD1 and found seven theoretical phosphorylation sites in, or immediately before, the NOD1 Caspase Activation Domain (CARD). Two of these, serine 7 and tyrosine 49 are also found as rare polymorphisms in the African-American population and European-American populations respectively. Mutating serine 7 to either an aspartic acid or an asparagine to mimic the potential impact of phosphorylation or the polymorphism respectively did not affect the response of NOD1 to ligand-mediated NFκB signalling.
