Impact of viability, ischemia, scar tissue, and revascularization on outcome after aborted sudden death.
van der Burg AE, Bax JJ, Boersma E, Pauwels EK, van der Wall EE, Schalij MJ
Background: Survivors of aborted sudden death attributable to ventricular arrhythmias in the presence of coronary artery disease are at risk for recurrences. The substrate underlying these arrhythmias is not clear, and therefore the relation between ischemia, viability, scar tissue (and revascularization), and the incidence of ventricular arrhythmias (and survival) was studied over up to 3 years. Methods and results: One hundred fifty-three survivors of sudden death underwent stress-rest perfusi...

Perioperative assessment of left ventricular function by pressure-volume loops using the conductance catheter method.
Tulner SAF, Klautz RJM, van Rijk-Zwikker GL, Engbers FHM, Bax JJ, Baan J, van der Wall EE, Dion RA, Steendijk P
Unlabelled: Interpretation of perioperative measurements of cardiac function during cardiac surgery is complicated by changes in loading conditions induced by anesthesia, cardiopulmonary bypass (CPB), and the surgical procedure itself. Quantification of left ventricular (LV) function by pressure-volume relations as obtained by the conductance catheter would be advantageous because load-independent indices can be determined. Accordingly, we evaluated methodological aspects of the conductance-cath...

Proliferation and apoptosis in bovine placentomes during pregnancy and around induced and spontaneous parturition as well as in cows retaining the fetal membranes.
Boos A, Janssen V, Mülling C
Placental growth can be achieved by either cellular proliferation or hypertrophy. Tissue regeneration and the nutrition of the fetus via embryotrophe require high rates of cellular turnover and the so-called pre-term 'maturation' of the placenta is correlated with a reduction of maternal crypt epithelial cells. Placentomes of 45 pregnant cows were collected from an abattoir to assess the role of proliferation and apoptosis in placental physiology and pathology. Placentomes were also ta...

Complex protein-DNA dynamics at the latent origin of DNA replication of Epstein-Barr virus.
Ritzi M, Tillack K, Gerhardt J, Ott E, Humme S, Kremmer E, Hammerschmidt W, Schepers A
The sequential binding of the origin recognition complex (ORC), Cdc6p and the minichromosome maintenance proteins (MCM2-7) mediates replication competence at eukaryotic origins of DNA replication. The latent origin of Epstein-Barr virus, oriP, is a viral origin known to recruit ORC. OriP also binds EBNA1, a virally encoded protein that lacks any activity predicted to be required for replication initiation. Here, we used chromatin immunoprecipitation and chromatin binding to compare the cell-cycl...

Pulmonary artery remodeling in transposition of the great arteries: relevance for neoaortic root dilatation.
Lalezari S, Hazekamp MG, Bartelings MM, Schoof PH, Gittenberger-De Groot AC
Objective: Transposition of the great arteries is currently treated by performing the arterial switch operation. Dilatation of the neoaortic root is a late complication with unknown cause. Samples of patients with untreated transposition of the great arteries and patients with normally related great arteries were compared to investigate a possible role for vascular remodeling in the dilatation process. Methods: Aortic and pulmonary artery vessel wall and sinus samples were taken from 20 untreate...

Early versus delayed revascularization in patients with ischemic cardiomyopathy and substantial viability: impact on outcome.
Bax JJ, Schinkel AF, Boersma E, Rizzello V, Elhendy A, Maat A, Roelandt JR, van der Wall EE, Poldermans D
Background: Patients with ischemic cardiomyopathy and viable myocardium may improve in function and prognosis following revascularization. Delayed revascularization may result in less favorable outcome, and therefore the impact of timing of revascularization on long-term outcome was evaluated. Methods and results: Patients (n=85) with ischemic cardiomyopathy and substantial viability (>or=25% of the left ventricle) on dobutamine stress echocardiography underwent surgical revascularization. Ba...

Effect of atorvastatin on myocardial contractile reserve assessed by tissue Doppler imaging in moderately hypercholesterolemic patients without heart disease.
Bountioukos M, Rizzello V, Krenning BJ, Bax JJ, Kertai MD, Vourvouri EC, Schinkel AF, Biagini E, Boersma E, Roelandt JR, Poldermans D
An improvement in myocardial longitudinal systolic velocities, assessed by pulsed-wave tissue Doppler imaging during low-dose dobutamine infusion, was observed at 6-month follow-up after 6 months of treatment with atorvastatin. Our findings indicate a favorable effect of atorvastatin on contractile reserve, possibly through an enhancement of flow-dependent coronary dilatation during stress.

Citrullination of synovial proteins in murine models of rheumatoid arthritis.
Vossenaar ER, Nijenhuis S, Helsen MM, van der Heijden A, Senshu T, van den Berg WB, van Venrooij WJ, Joosten LA
Objective: Antibodies directed to citrulline-containing proteins are highly specific for rheumatoid arthritis (RA) and can be detected in up to 80% of patients with RA. Citrulline is a nonstandard amino acid that can be incorporated into proteins only by posttranslational modification of arginine by peptidylarginine deiminase (PAD) enzymes. The objective of this study was to investigate the presence of anticitrulline antibodies, PAD enzymes, and citrullinated antigens in mouse models of both acu...
