Elhendy A, Schinkel AF, van Domburg RT, Bax JJ, Valkema R, Huurman A, Feringa HH, Poldermans D
Exercise stress electrocardiography is the recommended method for cardiac evaluation of patients with normal electrocardiograms (ECGs). There are no data to indicate an independent value of myocardial perfusion imaging (MPI) in predicting mortality in these patients. This study assessed the value of exercise stress MPI in predicting mortality in patients with normal baseline ECGs. We studied 319 patients (55 +/- 10 years of age; 180 men) with normal ECGs by exercise stress technetium-99m tetrofo...

Elucidation of the spatial ventricular gradient and its link with dispersion of repolarization.
Draisma HH, Schalij MJ, van der Wall EE, Swenne CA
The ventricular gradient, a notion conceived by Wilson et al during the 1930s, has contributed considerably to a better understanding of the ECG manifestations of the cardiac repolarization process. The power of the ventricular gradient is its ability to assess the primary factors that contribute to the T wave (i.e., heterogeneity of action potential morphology throughout the ventricles) in the presence of secondary factors contributing to the T wave (i.e., heterogeneity in ventricular depolariz...

Human T-cell responses to 25 novel antigens encoded by genes of the dormancy regulon of Mycobacterium tuberculosis.
Leyten EM, Lin MY, Franken KL, Friggen AH, Prins C, van Meijgaarden KE, Voskuil MI, Weldingh K, Andersen P, Schoolnik GK, Arend SM, Ottenhoff TH, Klein MR
The dormancy (DosR) regulon of Mycobacterium tuberculosis is expressed in vitro during hypoxia and low-dose nitric oxide stimulation. Tubercle bacilli are thought to encounter these conditions in humans during latent infection. In this study, immune responses were evaluated to 25 most strongly induced DosR-regulon-encoded proteins, referred to as latency antigens. Proliferation assays were performed using M. tuberculosis-specific T-cell lines and peripheral blood mononuclear cells (PBMC) from tu...

Atherosclerotic lesion size and vulnerability are determined by patterns of fluid shear stress.
Cheng C, Tempel D, van Haperen R, van der Baan A, Grosveld F, Daemen MJ, Krams R, de Crom R
Background: Atherosclerotic lesions are predominantly observed in curved arteries and near side branches, where low or oscillatory shear stress patterns occur, suggesting a causal connection. However, the effect of shear stress on plaque vulnerability is unknown because the lack of an appropriate in vivo model precludes cause-effect studies. Methods and results: We developed a perivascular shear stress modifier that induces regions of lowered, increased, and lowered/oscillatory (ie, with vortice...

Serial reevaluation for ARVD/C is indicated in patients presenting with left bundle branch block ventricular tachycardia and minor ECG abnormalities.
Kiès P, Bootsma M, Bax JJ, Zeppenfeld K, van Erven L, Wijffels MC, van der Wall EE, Schalij MJ
Introduction: Diagnosis of arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is based on a set of criteria proposed by the International Task Force (TF) for Cardiomyopathies in 1994. To fulfill these criteria, presence of both electrocardiographic and anatomical abnormalities must be assessed with ECG and imaging techniques, respectively. This may be difficult in patients with early/mild forms of the disease as detectable structural abnormalities may still be absent. We evaluate...

Selective targeting of liposomes to macrophages using a ligand with high affinity for the macrophage scavenger receptor class A.
Rensen PC, Gras JC, Lindfors EK, van Dijk KW, Jukema JW, van Berkel TJ, Biessen EA
Macrophages play an important role in inflammatory processes and are crucially involved in the onset and progression of atherosclerosis and tumorigenesis. Therefore, macrophages are regarded as an excellent target for therapeutic intervention. Since the scavenger receptor class A (SRA) is highly expressed on macrophages, we developed in the present study an SRA-specific particulate drug carrier by providing phosphatidylcholine liposomes with a targeting ligand for SRA. To enable firm association...
