Structural requirements for O-glycosylation of the mouse hepatitis virus membrane protein.
de Haan CA, Roestenberg P, de Wit M, de Vries AA, Nilsson T, Vennema H, Rottier PJ
The mouse hepatitis virus (MHV) membrane (M) protein contains only O-linked oligosaccharides. We have used this protein as a model to study the structural requirements for O-glycosylation. We show that MHV M is modified by the addition of a single oligosaccharide side chain at the cluster of 4 hydroxylamino acids present at its extreme amino terminus and identified Thr at position 5 as the functional acceptor site. The hydroxylamino acid cluster, which is quite conserved among O-glycosylated cor...

Effects of critical coronary stenosis on global systolic left ventricular function quantified by pressure-volume relations during dobutamine stress in the canine heart.
Steendijk P, Baan J, Van der Velde ET, Baan J
Objectives: In this study we quantified the effects of a critical coronary stenosis on global systolic function using pressure-volume relations at baseline and during incremental dobutamine stress. Background: The effects of coronary stenosis have previously been analyzed mainly in terms of regional (dys)function. Global hemodynamics are generally considered normal until coronary flow is substantially reduced. However, pressure-volume analysis might reveal mechanisms not fully exposed by potenti...

Trends in treatment and long-term survival of thyroid cancer in southeastern Netherlands, 1960-1992.
Kuijpens JL, Hansen B, Hamming JF, Ribot JG, Haak HR, Coebergh JW
Thyroid cancer (TC), comprising less than 1% of all cancers in the Netherlands, has a good prognosis in general. Controversy still remains on the extent of surgical treatment and the indication for additional Iodine-131 (131I) therapy in the management of differentiated TC. The aim of this study was to describe (changes in) the treatment of TC and to determine independent prognostic factors for crude and relative survival of differentiated TC diagnosed in general hospitals. This population-based...

The effect of antioxidative combination therapy on post hypoxic-ischemic perfusion, metabolism, and electrical activity of the newborn brain.
Shadid M, Moison R, Steendijk P, Hiltermann L, Berger HM, van Bel F
Reoxygenation and reperfusion after severe hypoxia and ischemia (HI) contribute substantially to birth asphyxia-related brain injury. Excess production of free radicals via metabolization of arachidonic acid, xanthine oxidase, and non-protein-bound iron play an important role. Cerebral reperfusion injury is characterized by a decrease in perfusion, oxygen consumption, and electrical activity of the brain. Reduction of free radical production may attenuate these features. We therefore induced sev...

Micro stent implantation in patients with acute myocardial infarction without anticoagulation: clinical experience with two different antithrombotic protocols.
Oemrawsingh PV, Schalij MJ, Udayachalerm W, van der Wall EE, Bruschke AV
The 4-week outcome following Micro stent implantation for acute myocardial infarction was assessed with the use of two different antithrombotic regimens. The patients were postprocedurally treated with acetyl salicylic acid (ASA) and heparin for 24-48 h (Group I; n = 52), or ASA and ticlopidine plus abciximab if indicated (Group II; n = 52). Stent implantation was successful in 49 patients (94%) of group I and in 46 patients (89%) of group II (NS). Subacute stent thrombosis occurred in nine pati...

Role of fine-needle aspiration biopsy and frozen section examination in determining the extent of thyroidectomy.
Hamming JF, Vriens MR, Goslings BM, Songun I, Fleuren GJ, van de Velde CJ
Traditionally the extent of thyroidectomy in patients with nodular thyroid disease has been based on peroperative frozen section examination (FS). Fine-needle aspiration biopsy (FNAB) and FS were evaluated with regard to the reliability to determine whether an operation for cancer is necessary. Both methods were performed in 240 patients operated for nodular thyroid disease and compared with the final histology on paraffin sections. Altogether 72 (30%) patients were found to have a malignant les...

Binding of human urokinase-type plasminogen activator to its receptor: residues involved in species specificity and binding.
Quax PH, Grimbergen JM, Lansink M, Bakker AH, Blatter MC, Belin D, van Hinsbergh VW, Verheijen JH
Urokinase-type plasminogen activator (UPA), particularly when bound to its receptor (UPAR), is thought to play a major role in local proteolytic processes, thus facilitating cell migration as may occur during angiogenesis, neointima and atherosclerotic plaque formation, and tumor cell invasion. To facilitate understanding of the need and function of the UPA/UPAR interaction in cell migration and vascular remodeling, we changed several amino acid residues in UPA so as to interfere with its intera...

Proposed synergistic effect of calcium channel blockers with lipid-lowering therapy in retarding progression of coronary atherosclerosis.
Jukema JW, van Boven AJ, Zwinderman AH, Van der Laarse A, Bruschke AV
Lipid-lowering therapy now has undoubtedly proven to be an effective therapeutic modality to retard the progression of coronary atherosclerosis. An additional approach for prevention of the progression of atherosclerosis is calcium channel blocker (CCB) treatment. Evidence indicating that CCBs inhibit atherosclerosis is less unequivocal than the clear evidence for lipid-lowering therapy. Many investigations support the view that a number of key processes in atherosclerosis may be influenced by C...

Contribution of synchronized atrial systole to left ventricular contraction in the newborn pig heart.
Klautz RJ, Baan J, Teitel DF
Synchronized atrial contraction may be much more important in the newborn, who has a faster heart rate and a less compliant ventricle, than in the adult. We therefore investigated the extent by which synchronized atrioventricular contraction contributes to cardiac output and cardiac work in a neonatal circulation, and whether this effect can be fully explained by the Starling mechanism. In neonatal piglets, left ventricular pressure and volume (conductance catheter) were measured during atrial a...
