Identification of host and donor cells in porcine homograft heart valve explants by fluorescence in situ hybridization.
Braun J, Hazekamp MG, Koolbergen DR, Sugihara H, Goffin YA, Huysmans HA, Cornelisse CJ
The pathogenesis of the primary tissue degeneration that limits the life-span of aortic and pulmonary homografts has still not been revealed. Histopathological studies on homograft explants have not given definitive insight into the eventual fate of donor cells, nor have they demonstrated the assumed importance of host cell ingrowth into the graft tissue. In this experimental study, fluorescence in situ hybridization (FISH) is introduced as a new approach to examine the distribution of host and...

Hemodynamic effects of chronic prenatal ventricular pacing for the treatment of complete atrioventricular block.
Liddicoat JR, Klein JR, Reddy VM, Klautz RJ, Teitel DF, Hanley FL
Background: Increasing the heart rate of the fetus with cardiac failure caused by complete AV block (CAVB) may allow delivery of a full-term, stable neonate with preserved ventricular function. Direct fetal pacing may be a feasible method to achieve this, but the effect of pacing on the structure and function of the rapidly developing fetal heart is unknown. Methods and results: CAVB was created in fetal lambs at 80% gestation by cryoablating the AV node. Epicardial ventricular pacing at 130 bpm...

Modified ultrafiltration after cardiopulmonary bypass in pediatric cardiac surgery.
Draaisma AM, Hazekamp MG, Frank M, Anes N, Schoof PH, Huysmans HA
Background: Cardiopulmonary bypass in children results in considerable water retention, especially in neonates and small infants. Dilution of plasma proteins increases water loss into the extravascular compartments. Excessive total body water may prolong ventilatory support and may contribute to a prolongation of intensive care convalescence. After discontinuation of cardiopulmonary bypass, modified ultrafiltration can be used to withdraw plasma water from the total circulating volume. Methods:...

The migration of human smooth muscle cells in vitro is mediated by plasminogen activation and can be inhibited by alpha2-macroglobulin receptor associated protein.
Wijnberg MJ, Quax PH, Nieuwenbroek NM, Verheijen JH
The plasminogen activation system is thought to be important in cell migration processes. A role for this system during smooth muscle cell migration after vascular injury has been suggested from several animal studies. However, not much is known about its involvement in human vascular remodelling. We studied the involvement of the plasminogen activation system in human smooth muscle cell migration in more detail using an in vitro wound assay and a matrix invasion assay. Inhibition of plasmin act...

Autosomal recessive liver phosphorylase kinase deficiency caused by a novel splice-site mutation in the gene encoding the liver gamma subunit (PHKG2).
van Beurden EA, de Graaf M, Wendel U, Gitzelmann R, Berger R, van den Berg IE
To facilitate mutation analysis of patients with an autosomal recessive form of liver phosphorylase kinase deficiency, the genomic structure of the gene encoding the testis/liver gamma subunit (PHKG2) was established. The gene consist of 10 exons. The translation start site is located in exon 2. Analysis of DNA from two female siblings, affected with liver phosphorylase kinase deficiency, by exon specific amplification followed by direct sequencing, revealed a single donor splice site mutation i...

Ischemic heart disease: value of MR techniques.
van der Wall EE, van Rugge FP, Vliegen HW, Reiber JH, de Roos A, Bruschke AV
Background: The cardiovascular applications of magnetic resonance (MR) techniques in coronary artery disease have increased considerably in recent years. Technical advantages of MR imaging are the excellent spatial resolution, the characterization of myocardial tissue, and the potential for three-dimensional imaging. These characteristics allow the accurate assessment of left ventricular mass and volume, the differentiation of infarcted from normal tissue, and the determination of systolic wall...

Apoptin induces apoptosis in human transformed and malignant cells but not in normal cells.
Danen-Van Oorschot AA, Fischer DF, Grimbergen JM, Klein B, Zhuang S, Falkenburg JH, Backendorf C, Quax PH, Van der Eb AJ, Noteborn MH
The chicken anemia virus protein apoptin induces a p53-independent, Bcl-2-insensitive type of apoptosis in various human tumor cells. Here, we show that, in vitro, apoptin fails to induce programmed cell death in normal lymphoid, dermal, epidermal, endothelial, and smooth-muscle cells. However, when normal cells are transformed they become susceptible to apoptosis by apoptin. Long-term expression of apoptin in normal human fibroblasts revealed that apoptin has no toxic or transforming activity i...

Equine arteritis virus.
Glaser AL, Chirnside ED, Horzinek MC, de Vries AA
Equine arteritis virus (EAV) is a small, enveloped, positive-stranded RNA virus, in the family Arteriviridae , W.H.ich can infect both horses and donkeys. While the majority of EAV infections are asymptomatic, acutely infected animals may develop a wide range of clinical signs, including pyrexia, limb and ventral edema, depression, rhinitis, and conjunctivitis. The virus may cause abortion and has caused mortality in neonates. After natural EAV infection, most horses develop a solid, long-term i...

Oxidative stress during post-hypoxic-ischemic reperfusion in the newborn lamb: the effect of nitric oxide synthesis inhibition.
Dorrepaal CA, van Bel F, Moison RM, Shadid M, van de Bor M, Steendijk P, Berger HM
Post-hypoxic-ischemic (HI) reperfusion induces endothelium and neurons to produce excessive amounts of nitric oxide and superoxide, leading to peroxynitrite formation, release of protein-bound metal ions (i.e. iron), and cytotoxic oxidants. We produced severe HI in 18 newborn lambs and serially determined plasma prooxidants (non-protein-bound iron), lipid peroxidation (malondialdehyde), and antioxidative capacity [ratio of ascorbic acid/dehydroascorbic acid (AA/DHA), alpha-tocopherol, sulfhydryl...

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...

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...
