Value of fast gradient echo magnetic resonance angiography as an adjunct to coronary arteriography in detecting and confirming the course of clinically significant coronary artery anomalies.
Vliegen HW, Doornbos J, de Roos A, Jukema JW, Bekedam MA, van der Wall EE
We investigated the additional value of magnetic resonance (MR) angiography in 12 patients with clinically significant coronary anomalies. In 5 patients, the referring cardiologist requested additional evaluation because coronary arteriography was inconclusive about the course of the anomaly. For comparison, 7 patients with known anomalous coronary arteries were collected from our database. In these patients, there had been no doubt about the course of the anomalous coronary arteries. MR angiogr...

Detection and quantification of dysfunctional myocardium by magnetic resonance imaging. A new three-dimensional method for quantitative wall-thickening analysis.
Holman ER, Buller VG, de Roos A, van der Geest RJ, Baur LH, van der Laarse A, Bruschke AV, Reiber JH, van der Wall EE
Background: Regional left ventricular dysfunction is a major consequence of myocardial ischemia, and its extent determines long-term prognosis. Accurate and reproducible analysis of left ventricular dysfunction is therefore useful for risk stratification and patient management. Methods and results: Short-axis cardiac cine magnetic resonance (MR) imaging was performed in 25 patients after anterior myocardial infarction at 21 +/- 2.1 days after the acute onset. The MR images were analyzed with the...

The Genome Organization of the Nidovirales: Similarities and Differences between Arteri-, Toro-, and Coronaviruses.
de Vries AAF, Horzinek MC, Rottier PJM, de Groot RJ
Viruses in the families Arteriviridae and Coronaviridae have enveloped virions which contain nonsegmented, positive-stranded RNA, but the constituent genera differ markedly in genetic complexity and virion structure. Nevertheless, there are striking resemblances among the viruses in the organization and expression of their genomes, and sequence conservation among the polymerase polyproteins strongly suggests that they have a common ancestry. On this basis, the International Committee on Taxonomy...

Bone matrix degradation by the plasminogen activation system. Possible mechanism of bone destruction in arthritis.
Ronday HK, Smits HH, Quax PH, van der Pluijm G, Löwik CW, Breedveld FC, Verheijen JH
The observed increase in urokinase-type plasminogen activator (u-PA) and its receptor (u-PAR) in synovial tissue of patients with rheumatoid arthritis (RA) suggests pathophysiological involvement of the plasminogen activation (PA) system in inflammatory joint disease. In the present study, we investigated the capacity of the PA system to degrade non-mineralized and mineralized bone-like matrix in vitro as a model for bone destruction. Transfected mouse LB6 cell lines, that expressed either human...

[Equine arteritis virus: clinical symptoms and prevention].
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...

Perinatal left ventricular performance in fetal sheep: interaction between oxygen ventilation and contractility.
Berning RA, Klautz RJ, Teitel DF
Left ventricular (LV) output nearly triples at birth, in association with increases in serum catecholamines. Similar increases in catecholamines in utero, however, do not increase output. We hypothesized that catecholamines increase contractility in utero, but that output cannot increase until LV loading conditions are changed by oxygen ventilation. To address this hypothesis, we studied nine fetal sheep acutely placed in a warm water bath (40 degrees C). Conductance and manometric catheters wer...

Human testicular germ cell tumours express inhibin subunits, activin receptors and follistatin mRNAs.
van Schaik RH, Wierikx CD, Looijenga LH, Oosterhuis JW, de Jong FH
Germ cell development is influenced by activin and inhibin, which are produced by Sertoli cells. Activin also affects differentiation of mouse embryonal carcinoma cells, which, to a certain extent, resemble the embryonal carcinoma component of germ cell tumours. Therefore, the expression of inhibin/activin subunits, of activin receptors and of the activin-binding protein follistatin was studied in testicular germ cell tumours, using RNAase protection assays. Testicular germ cell tumours of adole...

Nitric oxide inhibition after hypoxia-ischemia elevates pulmonary arterial pressure and increases oxygen need.
de Beaufort AJ, Lopes Cardozo RH, Dorrepaal CA, Steendijk P, Van Der Velde ET, Van Bel F
Inhibition of nitric oxide (NO) production may reduce post-hypoxic-ischemic (HI) neonatal brain damage, but may also induce pulmonary hypertension by inhibiting endogenous NO production in the pulmonary vascular bed. The aim of this study was to evaluate the effect of nitric oxide inhibition on pulmonary artery pressure and oxygen need after hypoxic ischemia. Severe HI was produced in 18 newborn lambs. After completion of HI the lambs were divided into three groups of 6 animals receiving either...

Restriction coefficients of low molecular weight solutes and macromolecules during peritoneal dialysis.
Ho-dac-Pannekeet MM, Koopmans JG, Struijk DG, Krediet RT
The intrinsic permeability of the peritoneal membrane can be functionally represented by the restriction coefficient (RC). The RC can be calculated as the exponent of the power relation between the mass transfer area coefficients (MTACs) of various solutes and their free diffusion coefficients in water. When the RC = 1.0, transport is determined by free diffusion only, as is expected for low molecular weight (LMW) solutes. A RC > 1.0 suggests that transport is restricted by the peritoneal mem...

Isolated hepatic perfusion in the pig with TNF-alpha with and without melphalan.
Borel Rinkes IH, de Vries MR, Jonker AM, Swaak TJ, Hack CE, Nooyen PT, Wiggers T, Eggermont AM
Isolated limb perfusion with tumour necrosis factor alpha (TNF-alpha) and melphalan is well tolerated and highly effective in irresectable sarcoma and melanoma. No data are available on isolated hepatic perfusion (IHP) with these drugs for irresectable hepatic malignancies. This study was undertaken to assess the feasibility of such an approach by analysing hepatic and systemic toxicity of IHP with TNF-alpha with and without melphalan in pigs. Ten healthy pigs underwent IHP. After vascular isola...

Effect of post-hypoxic-ischemic inhibition of nitric oxide synthesis on cerebral blood flow, metabolism and electrocortical brain activity in newborn lambs.
Dorrepaal CA, Shadid M, Steendijk P, Van der Velde ET, Van de Bor M, Baan J, Van Bel F
Since an excessive production of nitric oxide upon reperfusion/reoxygenation may play an important role in post-hypoxic-ischemic (HI) brain injury, we investigated whether immediate post-HI blockade of nitric oxide synthesis by N-omega-nitro-L-arginine (NLA) may reduce this injury. In 18 newborn lambs, subjected to severe HI, changes from pre-HI values were measured for carotid blood flow (Qcar [ml/min]) as a measure of changes in brain blood flow, (relative) cerebral metabolic rate of oxygen (C...

Leukocyte migration in experimental inflammatory bowel disease.
Van Rees EP, Palmen MJ, Van De Goot FR, Macher BA, Dieleman LA
Emigration of leukocytes from the circulation into tissue by transendothelial migration, is mediated subsequently by adhesion molecules such as selectins, chemokines and integrins. This multistep paradigm, with multiple molecular choices at each step, provides a diversity in signals. The influx of neutrophils, monocytes and lymphocytes into inflamed tissue is important in the pathogenesis of chronic inflammatory bowel disease. The importance of each of these groups of adhesion molecules in chron...

Cost-benefit analysis of vaccination against paratuberculosis in dairy cattle.
van Schaik G, Kalis CH, Benedictus G, Dijkhuizen AA, Huirne RB
Paratuberculosis is an infectious and incurable disease which causes considerable economic losses in dairy cattle, due mainly to premature disposal and losses of milk production. In 1984 the Animal Health Service North-Netherlands started a vaccination trial in which young calves were vaccinated once, to test whether vaccination reduced the production losses and whether the overall costs of vaccination were outweighed by the benefits. Vaccination against paratuberculosis reduced the number of cl...

[Hypertension caused by licorice consumption].
Seelen MA, de Meijer PH, Braun J, Swinkels LM, Waanders H, Meinders AE
In a 38-year-old woman who was hospitalized because of hypertension and hypokalaemic alkalosis, the intake of liquorice (200 g per day) was proven to be the cause. A liquorice provocation test produced all the expected clinical and biochemical abnormalities. Some kinds of liquorice contain glycyrrhetic acid which inhibits the enzyme 11-beta-hydroxysteroid dehydrogenase (e.g. in the kidney) leading to decreased transformation of cortisol into cortisone. The mineralocorticoid action of cortisol ca...

Intraarterial pressure gradients after randomized angioplasty or stenting of iliac artery lesions. Dutch Iliac Stent Trial Study Group.
Tetteroo E, Haaring C, van der Graaf Y, van Schaik JP, van Engelen AD, Mali WP
Purpose: To determine initial technical results of percutaneous transluminal angioplasty (PTA) and stent procedures in the iliac artery, mean intraarterial pressure gradients were recorded before and after each procedure. Methods: We randomly assigned 213 patients with typical intermittent claudication to primary stent placement (n = 107) or primary PTA (n = 106), with subsequent stenting in the case of a residual mean pressure gradient of > 10 mmHg (n = 45). Eligibility criteria included ang...

Systolic coronary flow reduction in the canine heart in situ: effects of left ventricular pressure and elastance.
Baan J, Steendijk P, Mikuniya A, Baan J
In the externally perfused coronary bed of the isolated heart, LV elastance (Elv) rather than LV pressure (Plv) appears to be the major factor responsible for systolic coronary flow reduction, although effects of both have been demonstrated. However, normal perfusion in the presence of intact autoregulation in the heart in situ may modify these effects. To investigate the systolic coronary flow (Qsyst) responses to changes in end-systolic Elv and in systolic Plv in the intact coronary bed, we st...
