cis-acting elements in the lytic origin of DNA replication of Epstein-Barr virus.
Schepers A, Pich D, Mankertz J, Hammerschmidt W
oriLyt, the cis-acting element of Epstein-Barr virus, mediates viral DNA replication in the lytic phase of the virus's life cycle. Oligonucleotide-directed in vitro mutagenesis of oriLyt plasmids allowed the identification of two noncontiguous components within the complex structure of oriLyt. Both components were indispensable for DNA replication of this origin. The upstream component colocalized with the promoter of the viral BHLF1-encoding gene, and mutants affecting DNA replication affe...

Left ventricular stroke volume by single and dual excitation of conductance catheter in dogs.
Steendijk P, Van der Velde ET, Baan J
The conductance method employs a multielectrode catheter to measure intracavitary electric conductance from which left ventricular volume is estimated. A dual-excitation method introduced by us uses a more homogeneous electric field and thereby should enable more accurate volume estimation. In six anesthetized open-chest dogs we compared stroke volume obtained from electromagnetic flow probes with the conventional single-excitation method and with the new dual-excitation conductance method. Cava...

Effects of inoculum route and dose on the immune response of common carp, Cyprinus carpio to the blood parasite, Trypanoplasma borreli.
Jones SR, Palmen M, van Muiswinkel WB
Carp were inoculated intramuscularly (im) or intraperitoneally (ip) with different doses of live Trypanoplasma borreli. Prepatent period was shortened by using the im route and by increasing the dose. Haematocrit was reduced following im inoculation with 9.5 x 10(5) parasites. Most fish recovered between 8 and 13 weeks post-inoculation (wpi). Neither parasitaemia nor anaemia was detected in any recovered fish following homologous challenge. An enzyme-linked immunosorbent assay was developed to q...

[Effect of increasing protein ingestion on the nitrogen balance of mechanically ventilated critically ill patients receiving total parenteral nutrition].
van der Heijden A, Verbeek MJ, Schreurs VV, Akkermans LM, Vos A
The amount of protein recommended to minimise N loss in critically ill patients receiving total parenteral nutrition (TPN) varies in the literature. Therefore, we studied the effect of increased protein intake on the N balance, administering TPN with either 1.2 g protein/kg/day (low N diet) or 1.8 g protein/kg/day (high N diet). Fifteen mechanically ventilated critically ill patients were studied in a surgical intensive care unit. After at least two days of standard TPN, patients were randomly a...

Quantitation of global and regional left ventricular function by cine magnetic resonance imaging during dobutamine stress in normal human subjects.
van Rugge FP, Holman ER, van der Wall EE, de Roos A, van der Laarse A, Bruschke AV
Magnetic resonance imaging (MRI) provides high-resolution images of the heart. However, physical exercise during MRI is difficult due to space restriction and motion artefacts. To evaluate the feasibility of MRI during stress conditions, dobutamine was used as an alternative to exercise. Haemodynamics, ventricular volumes and wall thickening were measured at rest and during peak dobutamine infusion (15 micrograms.kg-1 x min-1) in 23 normal human subjects. To calculate left ventricular volumes, e...

Comparison of diltiazem standard formulation and diltiazem controlled release in patients with stable angina pectoris: a randomized, double-blind, cross-over, multicenter study.
Vliegen HW, van der Wall EE, Kragten JA, Holwerda NJ, Schenkel WM, Muijs van de Moer WM, ten Kate JB, Mulder PG, Bruschke AV
In a randomized, double-blind, cross-over, multicenter study with a placebo run-in phase, the efficacy and safety of two oral formulations of diltiazem, standard three or four times daily (t.i.d. or q.i.d.) and controlled release twice daily (b.i.d.), were compared in 49 patients with stable angina pectoris. ST-segment depression at maximum exercise 12 h after tablet intake was less frequently observed with diltiazem controlled release than with standard diltiazem (34 of 49, 69% vs. 43 of 49, 88...

Effect of coronary occlusion and reperfusion on local electrical resistivity of myocardium in dogs.
Steendijk P, van Dijk AD, Mur G, van der Velde ET, Baan J
The effect of coronary occlusion and reperfusion on myocardial electrical resistivity was studied in nine anesthetized open-chest dogs. Anisotropic resistivity was measured on the anterior free wall of the left ventricle (LV) before (control) and during transient occlusion of the left anterior descending (LAD) coronary artery, and during reperfusion. To measure local resistivity longitudinal (RL) and transverse (RT) to epicardial muscle fiber direction, a sensor was developed based on the four e...

An element in the visual field is just a conjunction of attributes: a critique of Bundesen (1991)
van der Velde F, van der Heijden AH
Nissen (1985) presented results showing that in partial-report experiments, selection by location was different from selection by color or by shape. Bundesen (1991) presented a reinterpretation of these results, claiming that they can also be explained by a model in which location selection is treated on a par with selection by color or by shape. We will show that the analysis given by Bundesen is based on a special relation between an "element" in the visual field and its location, wh...

Hearing and language in preschool very low birthweight children.
Weisglas-Kuperus N, Baerts W, de Graaf MA, van Zanten GA, Sauer PJ
To get more insight into preschool language and hearing in high-risk very low birthweight (VLBW) children, we conducted a prospective study in a cohort of 79 children. The prevalence of language impairment and hearing loss at age 3-4 years, their relationship to each other as well as to perinatal conditions, neurodevelopmental outcome and the home environment are described. Mild hearing loss was found in 26%, moderate hearing loss in 13% and severe hearing loss in 3% of the children. None of the...

Myocardial perfusion and performance after indomethacin administration in newborn lambs.
Klautz RJ, van Bel F, Teitel DF, Steendijk P, Baan J
Indomethacin is a drug widely used to achieve pharmacologic closure of a patent ductus arteriosus in the premature infant. In several vascular beds (brain, kidney, intestine), indomethacin has been shown to cause vasoconstriction. Possible negative effects on myocardial blood flow and performance could be deleterious in premature infants with limited cardiac reserve. Before, during, and 30 and 60 min after administration of 1 mg.kg-1 of indomethacin in nine newborn lambs, we measured coronary bl...

The role of position in object selection in vision.
van der Heijden AH
Within contemporary visual-information-processing psychology, two classes of selective-attention theories can be distinguished: position-not-special theories and position-special theories. The position-not-special theories postulate that attentional selection by colour, by form, and by position are equivalent selective operations. The position-special theories assume that selection by position is more basic or direct than selection by colour or by form. Examples of both types of theory are brief...

Advancement of meiotic resumption in graafian follicles reduces fertility in the rat.
Mattheij JA, Swarts JJ, van der Heijden AJ, van Helvoort AL, Kusters IC
Fertile life of oocytes is usually considered to be related to ovulation time. In the present study, fertile life of rat oocytes was studied in relation to resumption of meiosis. In pro-oestrus, meiotic resumption without concomitant ovulation was induced in most graafian follicles by injection of a small amount of LH or FSH followed by Nembutal. These follicles either ovulated or developed into luteinized unruptured follicles if Ovalyse (a GnRH analogue) was given 8 h after LH or FSH. In subseq...

Surgery for membranous subaortic stenosis. Long-term follow-up.
Hazekamp MG, Frank M, Hardjowijono R, Quaegebeur JM, Ottenkamp J, Huysmans HA
From 1958 to 1992, 105 patients were operated for discrete (or membranous) subaortic stenosis (DSAS). Our surgical techniques changed during this period. Before 1980 DSAS was removed by a sharp excision leaving the part on the mitral valve untouched (n = 58). After 1980 blunt dissection was used to enucleate DSAS completely (n = 47). The operation for DSAS was combined with aortic valve replacement (AVR) in 7 instances. Follow-up with recent echo-Doppler studies was complete in 100 patients. Rec...

Cerebral hemodynamics and oxygenation in preterm infants after low-vs. high-dose surfactant replacement therapy.
Dorrepaal CA, Benders MJ, Steendijk P, van de Bor M, van Bel F
In thirteen preterm infants receiving surfactant (Curosurf) replacement therapy, changes in cerebral hemodynamics and oxygenation were investigated by near infrared spectroscopy. Surfactant instillation led to an instantaneous increase in cerebral blood volume (CBV) in all infants, which was primarily due to an increase in deoxygenated hemoglobin. Five infants received a low dose (100 mg/kg = 1.25 ml/kg) of surfactant and 8 a high dose (200 mg/kg = 2.50 ml/kg). A significantly larger increase in...

The value of the stentless biovalve prosthesis. An experimental study.
Hazekamp MG, Goffin YA, Huysmans HA
Clinical use of the stentless bioprosthesis has not yet been accepted world-wide. Experimental studies are scarce. In a study in growing pigs, 23 aortic valve replacements were performed (7 stented bioprostheses (STB), 10 stentless bioprostheses (SLB) and 6 cryopreserved homografts (CAH)). Valves were studied macroscopically and microscopically after explantation. Five animals died between 1.5 and 4 months after implantation. Two STBs showed extreme calcific degeneration. A third STB animal died...

Histological organization of the right and left atrioventricular valves of the chicken heart and their relationship to the atrioventricular Purkinje ring and the middle bundle branch.
Lu Y, James TN, Bootsma M, Terasaki F
In the avian heart the right and left atrioventricular (AV) valves not only exhibit their own special anatomical characteristics, but they also are in close proximity to the conduction system. The right AV valve is a single, spiral plane of myocardium, in remarkable contrast to the fibrous structure characteristic of the mammalian tricuspid valve. A ring of Purkinje tissue encircles the avian right AV orifice and connects to the muscular valve. The chicken has no crista supraventricularis, its r...

Sequential analysis of infarcted and normal myocardium in piglets using in vivo gadolinium-enhanced MR images.
van Dijkman PR, Höld KM, van der Laarse A, Holman ER, Ozdemir HI, van der Nat TH, de Roos A, van der Wall EE
Gadolinium-enhanced magnetic resonance (MR) imaging was performed before, and 1 and 3 wk after coronary occlusion in domestic piglets. After administration of the contrast agent gadopentetate dimeglumine, two different enhancement patterns within the infarcted region were observed. The first pattern, showing peripheral enhancement of the infarcted region with absence of contrast in the center, was seen at 1 wk after occlusion at 5 min after administration of the contrast agent. The second patter...
