Antioxidant defense systems in newborns undergoing phototherapy.
Akisü M, Yilmaz D, Tüzün S, Kültürsay N
This paper was designed to investigate whether phototherapy is an oxidative stress in newborn infants undergoing phototherapy. A day-light continuous phototherapy was given to jaundiced 20 term and 16 preterm newborns for 72 hours. We measured serum vitamin E and the activities of red blood cell anti-oxidation enzymes (superoxide dismutase, catalase and glutathione peroxidase) before and after 72 h of phototherapy. Serum vitamin E levels were not different before and after 72 h of phototherapy i...

Identification of a novel structural protein of arteriviruses.
Snijder EJ, van Tol H, Pedersen KW, Raamsman MJ, de Vries AA
Arteriviruses are positive-stranded RNA viruses with an efficiently organized, polycistronic genome. A short region between the replicase gene and open reading frame (ORF) 2 of the equine arteritis virus (EAV) genome was previously assumed to be untranslated. However, here we report that this segment of the EAV genome contains the 5' part of a novel gene (ORF 2a) which is conserved in all arteriviruses. The 3' part of EAV ORF 2a overlaps with the 5' part of the former ORF 2 (now r...

Rapid nucleolytic degradation of the small cytoplasmic Y RNAs during apoptosis.
Rutjes SA, van der Heijden A, Utz PJ, van Venrooij WJ, Pruijn GJ
We have investigated the fate of the RNA components of small ribonucleoprotein particles in apoptotic cells. We show that the cytoplasmic Ro ribonucleoprotein-associated Y RNAs are specifically and rapidly degraded during apoptosis via a caspase-dependent mechanism. This is the first study describing the selective degradation of a specific class of small structural RNA molecules in apoptotic cells. Cleavage and subsequent truncation of Y RNAs was observed upon exposure of cells to a variety of a...

Electrocortical brain activity during hypoxia and hypotension in anesthetized newborn lambs.
van de Bor M, Meinesz J, Benders MJ, Steendijk P, Lopes Cardozo RH, van Bel F
Blood gas and blood pressure disturbances do influence cerebral blood flow in newborns. To what extent cerebral blood flow changes affect electrocortical brain activity remains uncertain. We studied the effect of severe hypoxia and hemorrhagic hypotension on carotid artery blood flow and electrocortical brain activity in newborn anesthetized lambs. During hypoxia carotid artery blood flow increased significantly, whereas electrocortical brain activity remained unchanged. The hemorrhagic hypotens...

Trace-level determination of polar flavour compounds in butter by solid-phase extraction and gas chromatography-mass spectrometry.
Adahchour M, Vreuls RJ, van der Heijden A, Brinkman UA
Volatile compounds are responsible for the aromas of butter. A simple technique for the determination of these components is described which is based on solid-phase extraction (SPE) after melting of the butter and separation of the aqueous phase from the fat. Volatile flavours present in the water fraction are collected by off-line SPE on cartidges packed with a copolymer sorbent. After desorption with 500 microliters of methyl acetate, 1-microliter aliquots are quantified and/or identified by g...

Treatment and prevention of coronary heart disease by lowering serum cholesterol levels; from the pioneer work of C.D. de Langen to the third "Dutch Consensus on Cholesterol".
Jukema JW, Simoons ML
In the beginning of this century a possible relation was observed between cholesterol-rich foods, blood cholesterol levels and atherosclerosis by "pioneers" in this field as Anitschkow and De Langen. In the second half of this century a definite link was established between serum cholesterol levels and development of coronary heart disease (CHD). In angiographic studies it has recently been shown that a decrease in total cholesterol as well as in low-density lipoprotein cholesterol lev...

Dynamic obstruction, an unusual complication after aortic valve replacement with a stentless porcine valve.
van Roosmalen RP, Baur LH, Braun J, Atsma DE, Hazekamp MG, van der Wall EE, Huysmans HA
In the early nineties, the stentless porcine aortic bioprosthesis has been reintroduced successfully. Because of the limited experience, knowledge of clinical complications is limited. Therefore, we describe an unusual complication of dynamic obstruction after aortic valve replacement with a stentless porcine valve in a 70 year old man 18 months after implantation. We discuss the complications of stentless aortic prostheses known so far, describe operative techniques used and their characteristi...

Diagnosis and management of anomalous origin of the right coronary artery from the left coronary sinus.
Bekedam MA, Vliegen HW, Doornbos J, Jukema JW, de Roos A, van der Wall EE
The anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva coursing between the aorta and the pulmonary artery or right ventricular outflow tract, is considered a potentially fatal abnormality which may require surgery. However, diagnosing the correct course with coronary arteriography may be difficult. Fast gradient echo magnetic resonance (MR) imaging can be helpful to identify and confirm the course of aberrant coronary arteries and their relationship to the surro...

Lipoprotein lipase activity is decreased in a large cohort of patients with coronary artery disease and is associated with changes in lipids and lipoproteins.
Henderson HE, Kastelein JJ, Zwinderman AH, Gagné E, Jukema JW, Reymer PW, Groenemeyer BE, Lie KI, Bruschke AV, Hayden MR, Jansen H
Lipoprotein lipase (LPL) is crucial in the hydrolysis of triglycerides (TG) in TG-rich lipoproteins in the formation of HDL particles. As both these lipoproteins play an important role in the pathogenesis of atherosclerotic vascular disease, we sought to assess the relationship between post-heparin LPL (PH-LPL) activity and lipids and lipoproteins in a large, well-defined cohort of Dutch males with coronary artery disease (CAD). These subjects were drawn from the REGRESS study, totaled 730 in nu...

Effect of the stromelysin-1 promoter on efficacy of pravastatin in coronary atherosclerosis and restenosis.
de Maat MP, Jukema JW, Ye S, Zwinderman AH, Moghaddam PH, Beekman M, Kastelein JJ, van Boven AJ, Bruschke AV, Humphries SE, Kluft C, Henney AM
It has proved difficult to identify high-risk patients for atherosclerosis and to determine how they might respond to medication. Recently, a common promoter variant of the human stromelysin-1 gene has been reported, which has been shown to affect the transcription. We investigated whether this polymorphism had any impact on the risk of events, especially restenosis and progression of coronary artery disease and whether the effect was modulated by treatment with pravastatin. The stromelysin-1 ge...

Postsurgical course of patients with congenitally corrected transposition of the great arteries.
Voskuil M, Hazekamp MG, Kroft LJ, Lubbers WJ, Ottenkamp J, van der Wall EE, Zwinderman KH, Mulder BJ
Because congenitally corrected transposition is a rare congenital anomaly, little is known about the prognosis of patients with this syndrome. The present study evaluated the functional status and clinical course of 73 patients (42 male and 31 female) aged 10 days to 73 years. Follow-up was 1 week to 37 years (mean 12.7 years). Particular attention was paid to the systemic right ventricle, considering the current controversies about long-term right ventricular function. Survival of patients with...

Pretreatment with allopurinol in cardiac hypoxic-ischemic reperfusion injury in newborn lambs exerts its beneficial effect through afterload reduction.
Shadid M, Van Bel F, Steendijk P, Dorrepaal CA, Moison R, Van der Velde ET, Baan J
The aim of this study was to determine whether allopurinol (ALLO) reduces reperfusion injury inflicted upon the heart resulting from excess production of free oxygen radicals after hypoxia and ischemia (HI) in newborn animals. We, therefore, produced severe HI in 13 newborn lambs by low O2-ventilation and blood volume reduction. One hour before HI seven lambs received ALLO (20 mg/kg i.v.), six received a placebo (CONT). Cardiac function and hemodynamic parameters were assessed by sequential meas...
