Oxygen wastage of stunned myocardium in vivo is due to an increased oxygen cost of contractility and a decreased myofibrillar efficiency.
Trines SA, Slager CJ, Onderwater TA, Lamers JM, Verdouw PD, Krams R
Objective: We investigated whether an increased oxygen cost of contractility and/or a decreased myofibrillar efficiency contribute to oxygen wastage of stunned myocardium. Because Ca(2+)-sensitizers may increase myofibrillar Ca(2+)-sensitivity without increasing cross-bridge cycling, we also investigated whether EMD 60263 restores myofibrillar efficiency and/or the oxygen cost of contractility. Methods: Regional fiber stress and strain were calculated from mesomyocardially implanted ultrasound c...

Building blocks for electronic spiking neural networks.
van Schaik A
We present an electronic circuit modelling the spike generation process in the biological neuron. This simple circuit is capable of simulating the spiking behaviour of several different types of biological neurons. At the same time, the circuit is small so that many neurons can be implemented on a single silicon chip. This is important, as neural computation obtains its power not from a single neuron, but from the interaction between a large number of neurons. Circuits that model these interacti...

Acute effects of pulmonary artery banding in sheep on right ventricle pressure-volume relations: relevance to the arterial switch operation.
Hon JK, Steendijk P, Khan H, Wong K, Yacoub M
The first stage of the two-stage arterial switch operation (ASO) for transposition of the great arteries (TGA) is associated with depressed ventricular function and an unstable immediate post-operative course. It is unclear if this is because of the acute increase in afterload of the thin-walled, low-pressure ventricle by pulmonary artery banding (PAB). To determine the acute effects of afterload increase on the contractile function of thin-walled ventricles, we studied the right ventricular pre...

Cloning and characterization of human liver cytosolic beta-glycosidase.
de Graaf M, van Veen IC, van der Meulen-Muileman IH, Gerritsen WR, Pinedo HM, Haisma HJ
Cytosolic beta-glucosidase (EC 3.2.1.21) from mammalian liver is a member of the family 1 glycoside hydrolases and is known for its ability to hydrolyse a range of beta-D-glycosides, including beta-D-glucoside and beta-D-galactoside. We therefore refer to this enzyme as cytosolic beta-glycosidase. We cloned the cDNA encoding the human cytosolic beta-glycosidase by performing PCR on cDNA prepared from total human liver RNA. Specific primers were based on human expressed sequence tags found in the...

Recombinant equine arteritis virus as an expression vector.
de Vries AA, Glaser AL, Raamsman MJ, Rottier PJ
Equine arteritis virus (EAV) is the prototypic member of the family Arteriviridae, which together with the Corona- and Toroviridae constitutes the order Nidovirales. A common trait of these positive-stranded RNA viruses is the 3'-coterminal nested set of six to eight leader-containing subgenomic mRNAs which are generated by a discontinuous transcription mechanism and from which the viral open reading frames downstream of the polymerase gene are expressed. In this study, we investigated whet...

A paradoxical exposure-duration effect in the Stroop task: temporal segregation between stimulus attributes facilitates selection.
La Heij W, van der Heijden AH, Plooij P
In comparison with the situation in which target and distractor are presented until response, Stroop interference substantially decreases when the target color is removed from the display 150-160 ms after stimulus onset (W. La Heij, N. A. Kaptein, A. C. Kalff, & L. de Lange, 1995; O. Neumann, 1986). Six experiments showed that this paradoxical exposure-duration effect is robust, that it is not due to the target's exposure duration per se, and that it is not due to an increased spatial s...

Totally extraperitoneal endoscopic repair of recurrent inguinal hernia.
van der Hem JA, Hamming JF, Meeuwis JD, Oostvogel HJ
Background: Conventional repair of recurrent inguinal hernia is associated with a re-recurrence rate as high as 35 per cent. Endoscopic mesh repair has promising results regarding both recurrence and complication rates. Methods: In a retrospective review, the results of endoscopic totally extraperitoneal repair were evaluated in 104 patients with 108 recurrent hernias. Follow-up was at least 1 year. Type of recurrence, time of occurrence after previous repair, duration of surgery, complications,...

[Treatment of intra-atrial reentry tachycardia by catheter ablation, using three-dimensional electro-anatomical map of the atrial activation pattern].
de Groot NM, Schalij MJ
A 30-year-old man, who had been treated surgically for tricuspid valve atresia as a boy, suffered from recurrent supraventricular tachycardias. These atrial reentry tachycardias are frequent post-operative complications in patients with congenital heart disease. The reentry circuit in these patients often circulates around areas of scar tissue or surgically created barriers such as incision scars and implanted synthetic material. A possible curative treatment of these arrhythmias is radiofrequen...

Cardiac remodeling after myocardial infarction is impaired in IGF-1 deficient mice.
Palmen M, Daemen MJ, Bronsaer R, Dassen WR, Zandbergen HR, Kockx M, Smits JF, van der Zee R, Doevendans PA
Objective: To obtain more insight in the role of IGF-1 in cardiac remodeling and function after experimental myocardial infarction. We hypothesized that cardiac remodeling is altered in IGF-1 deficient mice, which may affect cardiac function. Methods: A myocardial infarction was induced by surgical coronary artery ligation in heterozygous IGF-1 deficient mice. One week after surgery, left ventricular function was analyzed, and parameters of cardiac remodeling were measured. Results: No significa...

Endothelin-1 plasma concentration increases in the early phase of pulmonary hypertension development during respiratory distress syndrome: a study in newborn lambs.
de Vroomen M, Lopes Cardozo RH, Steendijk P, Frölich M, Baan J, van Bel F
Objective: Elevated plasma concentrations of endothelin-1 (ET-1) have been reported with pulmonary hypertension during respiratory distress syndrome (RDS). However, the exact role of ET-1 in the development of pulmonary hypertension during RDS is unclear. The relative time-course of changes in ET-1 concentrations and pulmonary artery pressure (P(ap)) during RDS may give insight in the role of ET-1. Methods: ET-1 and P(ap) changes were studied in an experimental model of RDS, induced by lung lava...

Investigation of serum response to PMP22, connexin 32 and P(0) in inflammatory neuropathies.
Kwa MS, van Schaik IN, Brand A, Baas F, Vermeulen M
We investigated serological immune responses against three major peripheral nerve myelin constituents in patients with immune-mediated neuropathies. Connexin 32 (Cx32), myelin protein zero (MPZ, P(0)) and peripheral myelin protein 22 (PMP22) were produced in Chinese hamster ovary (CHO)-K1 cells. From a panel of 25 Guillain-Barré syndrome (GBS) and 24 chronic inflammatory demyelinating polyneuropathy (CIDP) patients, only two patients showed reactivity towards Cx32 and P(0).

[Risk and economics of disease introduction to dairy farms].
van Schaik G
A more closed farming system will enhance the success of disease eradication programmes, because the introduction or re-introduction of infectious diseases is less likely. The objective of the study was to obtain input for the development of an on-farm decision support model to calculate the economic consequences of a more closed farming system. The input was based on bovine herpesvirus 1 (BHV1), since there were numerous data on this disease, but a more closed farming system will prevent introd...

Pulmonary valve insertion late after repair of Fallot's tetralogy.
Hazekamp MG, Kurvers MM, Schoof PH, Vliegen HW, Mulder BM, Roest AA, Ottenkamp J, Dion RA
Objectives: To analyze the results of pulmonary valve insertion late after initial repair of Fallot's tetralogy. Pulmonary insufficiency (PI) after correction of Fallot's tetralogy is usually well tolerated in the short term, but is associated with symptomatic right ventricular dilatation and an increased risk of ventricular arrhythmias over longer periods of time. Methods: From 1993 to July 2000, 51 patients were reoperated for PI at a mean age of 25.7+/-11.9 years. The mean age at in...

Identification of a novel cis-acting RNA element involved in nuclear export of hY RNAs.
Rutjes SA, Lund E, van der Heijden A, Grimm C, van Venrooij WJ, Pruijn GJ
Ro RNPs are small cytoplasmic RNA-protein complexes of unknown function that have been found in all metazoan cells studied so far. In human cells, Ro RNPs consist of one of four small RNA molecules, termed hY RNAs and at least two well-characterized proteins, Ro60 and La. In previous Xenopus laevis oocyte microinjection studies, we showed that an intact Ro60 binding site (Stem-loop 1) is a prerequisite for efficient nuclear export of hY1 RNA, whereas an intact La-binding site promotes nuclear re...
