Journal of magnetic resonance imaging : JMRI, Volume 6, Issue 6, 1 1 1996, Pages 948-949 Development of an MRI-compatible catheter for pacing the heart: initial in vitro and in vivo results. Jerzewski A, Pattynama PM, Steendijk P, Doornbos J, de Roos A, Baan J

An MRI-compatible catheter was developed for pacing the heart during MRI imaging. The device was tested in vitro and in vivo in 10 animal experiments, using spin-echo, gradient-echo, and echo-planar MRI sequences. Images were of good quality in all sequences. Pacing was effective without induced arrhythmias. Therefore, pacing the heart during MRI is feasible and seems to be safe when using dedicated hardware. Abstract

Perception & psychophysics, Volume 58, Issue 8, 1 1 1996, Pages 1224-1237 Attending to color with proper fixation. van der Heijden AH, Kurvink AG, de Lange L, de Leeuw F, van der Geest JN

In contemporary theorizing, there is a controversy about the role of spatial location in the selection of visual information; some theories postulate that position plays a unique role, whereas other theories hold that position is just one selection dimension that is not different from other dimensions, such as color and shape. In this context, a paradigm introduced by Tsal and Lavie (1988) promised to be of fundamental importance. With that paradigm, Tsal and Lavie found that, after reporting a... Abstract

Circulation, Volume 94, Issue 8, 1 1 1996, Pages 1913-1918 The Asp9 Asn mutation in the lipoprotein lipase gene is associated with increased progression of coronary atherosclerosis. REGRESS Study Group, Interuniversity Cardiology Institute, Utrecht, The Netherlands. Regression Growth Evaluation Statin Study. Jukema JW, van Boven AJ, Groenemeijer B, Zwinderman AH, Reiber JH, Bruschke AV, Henneman JA, Molhoek GP, Bruin T, Jansen H, Gagné E, Hayden MR, Kastelein JJ

Background: Many patients suffering from premature coronary artery disease report a family history for such events. A mutation in a particular gene, which confers susceptibility for atherosclerosis, will be found more frequently in individuals suffering from coronary atherosclerosis than in the general population. We have recently reported the identification of an Asp9 Asn substitution in the lipoprotein lipase (LPL) enzyme. We analyzed the impact of this mutation on the progression of coronary... Abstract

The veterinary quarterly, Volume 18, Issue 3, 1 1 1996, Pages 95-99 Equine arteritis virus: a review of clinical features and management aspects. Glaser AL, de Vries AA, Rottier PJ, Horzinek MC, Colenbrander B

Sero-epidemiological surveys have revealed that equine arteritis virus (EAV) is prevalent in most European countries. The virus causes sporadic cases of respiratory disease and abortion in horses, the incidence of which has increased in recent years. Mares and geldings eliminate virus after acute infection, but 30% to 60% of stallions become persistently infected. In these animals, EAV is maintained within the reproductive tract and is shed continuously in the semen. Persistent infection with EA... Abstract

European heart journal, Volume 17, Issue 8, 1 1 1996, Pages 1271-1278 Cardiac anatomy, function and metabolism in elite cyclists assessed by magnetic resonance imaging and spectroscopy. Pluim BM, Chin JC, De Roos A, Doornbos J, Siebelink HM, Van der Laarse A, Vliegen HW, Lamerichs RM, Bruschke AV, Van der Wall EE

We investigated whether left ventricular hypertrophy in elite cyclists is associated with functional changes or abnormal energy metabolism. Left ventricular hypertrophy is a powerful risk factor for sudden cardiac death with different prognostic significance among the various geometric forms. Cyclists may have a combination of mixed eccentric and concentric hypertrophy. Magnetic resonance imaging was used to define left ventricular mass, geometry and function. Thirteen highly trained male cyclis... Abstract

Molecular and cellular endocrinology, Volume 121, Issue 1, 1 1 1996, Pages 1-10 Differential regulation of inhibin/activin alpha- and beta A-subunit and follistin mRNAs by cyclic AMP and phorbol ester in cultured human granulosa-luteal cells. Tuuri T, Erämaa M, Van Schaik RH, Ritvos O

Granulosa cell-derived inhibin A (a dimer of alpha- and beta A-subunits), activin A (a homodimer of beta A-subunits) and the activin-binding protein follistatin are important regulators of human ovarian steroidogenesis. We here studied how 8-bromo-cAMP (8br-cAMP), a protein kinase A activator, and 12-O-tetradecanoylphorbol 13-acetate (TPA), a protein kinase C activator, affect the steady-state levels of alpha- and beta A-subunit and follistatin mRNAs in cultured human granulosa-luteal cells. 8br...

Angiology, Volume 47, Issue 7, 1 1 1996, Pages 633-642 The influence of angiographic endpoints on the outcome of lipid intervention studies. A proposal for standardization. REGRESS study group. Jukema JW, van Boven AJ, Zinderman AH, Bal ET, Reiber JH, Bruschke AV

The aims of this study were to evaluate the influence of different coronary angiographic endpoints on the outcome of lipid intervention studies and to formulate a proposal for angiographic endpoint standardization. In recent angiographic intervention studies a confusing diversity in angiographic endpoints has been used to determine the outcome. In addition, differences in study populations (eg, bypass patients included or not) could influence results. This makes comparisons between studies cumbe... Abstract

The Journal of infectious diseases, Volume 174, Issue 1, 1 1 1996, Pages 120-126 The role of nitric oxide in bacterial meningitis in children. Kornelisse RF, Hoekman K, Visser JJ, Hop WC, Huijmans JG, van der Straaten PJ, van der Heijden AJ, Sukhai RN, Neijens HJ, de Groot R

To investigate the role of nitric oxide (NO) in bacterial meningitis, concentrations in serum, cerebrospinal fluid (CSF), or both of the precursor (L-arginine) and degradation products of NO (nitrate, nitrite) and tumor necrosis factor (TNF)-alpha were measured in 35 patients and 30 controls. CSF nitrate levels were significantly elevated, mainly due to increased blood-brain barrier permeability, and are therefore not a good parameter for gauging endogenous NO production in the CSF compartment....

International journal of cardiac imaging, Volume 12, Issue 2, 1 1 1996, Pages 69-78 Left ventricular regression equations from single plane cine and digital X-ray ventriculograms revisited. Reiber JH, Viddeleer AR, Koning G, Schalij MJ, Lange PE

For the assessment of left ventricular volume from X-ray ventriculograms, widely known regression equations are used to correct for the irregular shape of the left ventricular lumen and the presence of the papillary muscles and trabeculations. These regression equations were derived in the late nineteen sixties and seventies. With all the changes in X-ray technology that have taken place over the past 20-30 years, the question was raised whether these regression equations were still valid. There... Abstract

International journal of cardiac imaging, Volume 12, Issue 2, 1 1 1996, Pages 79-83 Imaging of recurrent ventricular septal defect and supravalvular pulmonary stenosis eight years after assumed total surgical repair of tetralogy of Fallot. van Dijkman PR, Voskuil K, Hazekamp MG, van der Wall EE

A 42-year-old man underwent assumed total surgical repair of an acyanotic tetralogy of Fallot: a perimembranous ventricular septal defect (VSD) was closed with a dacron patch and myectomy of the infundibulum of the right ventricular outflow tract was performed. Reexamination eight years later revealed a large recurrent VSD and by surprise a narrow supravalvular ridge above rudimentary pulmonary cusps in the pulmonary trunk, leading to a pressure drop of 70 mmHg across the supravalvular stenosis....

The American journal of physiology, Volume 270, Issue 6 Pt 2, 1 1 1996, Pages H2149-56 Low external pH limits cell death of energy-depleted cardiomyocytes by attenuation of Ca2+ overload. Atsma DE, Bastiaanse EM, Van der Valk L, Van der Laarse A

We studied the effect of external pH (pHe) on cell injury, ATP content, and intracellular concentration of Ca2+ ([Ca2+]i), Na+ ([Na+]i), and H+ (pHi) during metabolic inhibition (NaCN + 2-deoxyglucose) in neonatal rat cardiomyocytes. Cell death during metabolic inhibition decreased at pHe < 7.4, with almost no cell death at pHe 6.0. Lowering pHe resulted in only temporary ATP conservation. During metabolic inhibition at pHe 7.4, [Ca2+]i rose from 86 +/- 44 nM to 2.5 +/- 0.4 microM, but at pHe... Abstract

Virology, Volume 220, Issue 2, 1 1 1996, Pages 367-376 Activation of oriLyt, the lytic origin of DNA replication of Epstein-Barr virus, by BZLF1. Schepers A, Pich D, Hammerschmidt W

oriLyt, the cis-acting element of the lytic origin of DNA replication of Epstein-Barr virus, is activated by the viral transactivator BZLF1 which belongs to the extended bZIP class of transcription factors. Seven binding sites for BZLF1, so-called ZRE sites, are located within oriLyt. By mutational analysis of individual ZRE sites, we found that lytic DNA replication is dependent on only four of these sites which colocate with the promoter of the BHLF1 gene. The remaining three ZRE sites distal... Abstract
