Acta physiologica (Oxford, England), Volume 203, Issue 4, 27 4 2011, Pages 409-418 The induction of mild hypothermia improves systolic function of the resuscitated porcine heart at no further sympathetic activation. Schwarzl M, Steendijk P, Huber S, Truschnig-Wilders M, Obermayer-Pietsch B, Maechler H, Pieske B, Post H

Aim: Mild hypothermia (MH) after cardiac arrest attenuates hypoxic brain injury and improves survival. As MH increases contractility in normal hearts, we hypothesized that MH improves cardiovascular function after cardiac arrest. Methods: In 16 anaesthetized pigs (64 ± 2 kg), ventricular fibrillation was induced electrically for 5 min. At 10 min after resuscitation and return of spontaneous circulation (ROSC), pigs were assigned to normothermia (NT, 38°C, n = 8) or MH (33°C, n = 8, intravascular... Abstract

Metabolic engineering, Volume 13, Issue 5, 17 3 2011, Pages 518-526 Increasing free-energy (ATP) conservation in maltose-grown Saccharomyces cerevisiae by expression of a heterologous maltose phosphorylase. de Kok S, Yilmaz D, Suir E, Pronk JT, Daran JM, van Maris AJ

Increasing free-energy conservation from the conversion of substrate into product is crucial for further development of many biotechnological processes. In theory, replacing the hydrolysis of disaccharides by a phosphorolytic cleavage reaction provides an opportunity to increase the ATP yield on the disaccharide. To test this concept, we first deleted the native maltose metabolism genes in Saccharomyces cerevisiae. The knockout strain showed no maltose-transport activity and a very low residual... Abstract

American journal of hypertension, Volume 24, Issue 9, 16 3 2011, Pages 999-1006 SNPs in microRNA binding sites in 3'-UTRs of RAAS genes influence arterial blood pressure and risk of myocardial infarction. Nossent AY, Hansen JL, Doggen C, Quax PH, Sheikh SP, Rosendaal FR

Background: We hypothesized that single nucleotide polymorphisms (SNPs) located in microRNA (miR) binding sites in genes of the renin angiotensin aldosterone system (RAAS) can influence blood pressure and risk of myocardial infarction. Methods: Using online databases dbSNP and TargetScan, we identified 10 SNPs in potential miR binding sites in eight RAAS-related genes, common in Caucasians. We genotyped a large case-control study on myocardial infarctions, the Study of Myocardial Infarctions LEi... Abstract

Thrombosis and haemostasis, Volume 106, Issue 1, 14 2 2011, Pages 1-19 Stabilisation of atherosclerotic plaques. Position paper of the European Society of Cardiology (ESC) Working Group on atherosclerosis and vascular biology. Ylä-Herttuala S, Bentzon JF, Daemen M, Falk E, Garcia-Garcia HM, Herrmann J, Hoefer I, Jukema JW, Krams R, Kwak BR, Marx N, Naruszewicz M, Newby A, Pasterkamp G, Serruys PW, Waltenberger J, Weber C, Tokgözoglu L

Plaque rupture and subsequent thrombotic occlusion of the coronary artery account for as many as three quarters of myocardial infarctions. The concept of plaque stabilisation emerged about 20 years ago to explain the discrepancy between the reduction of cardiovascular events in patients receiving lipid lowering therapy and the small decrease seen in angiographic evaluation of atherosclerosis. Since then, the concept of a vulnerable plaque has received a lot of attention in basic and clinical res... Abstract

American journal of medical genetics. Part A, Volume 155A, Issue 7, 10 2 2011, Pages 1661-1667 Adults with congenital heart disease: patients' knowledge and concerns about inheritance. van Engelen K, Baars MJ, van Rongen LT, van der Velde ET, Mulder BJ, Smets EM

With recent advances in medical and surgical management, most patients with congenital heart disease (CHD) survive to reproductive age. Current guidelines recommend counseling about inheritance and transmission of CHD to offspring. We evaluated whether adult CHD patients recalled having received information about the inheritance of their CHD, patients' knowledge about inheritance and their concerns in this regard. A questionnaire was sent to 486 non-syndromic CHD patients aged 20-45 years.... Abstract

BMC musculoskeletal disorders, Volume 12, 9 2 2011, Pages 130 A hinged external fixator for complex elbow dislocations: a multicenter prospective cohort study. Schep NW, De Haan J, Iordens GI, Tuinebreijer WE, Bronkhorst MW, De Vries MR, Goslings JC, Ham SJ, Rhemrev S, Roukema GR, Schipper IB, Sintenie JB, Van der Meulen HG, Van Thiel TP, Van Vugt AB, Verleisdonk EJ, Vroemen JP, Wittich P, Patka P, Van Lieshout EM, Den Hartog D

Background: Elbow dislocations can be classified as simple or complex. Simple dislocations are characterized by the absence of fractures, while complex dislocations are associated with fractures of the radial head, olecranon, or coronoid process. The majority of patients with these complex dislocations are treated with open reduction and internal fixation (ORIF), or arthroplasty in case of a non-reconstructable radial head fracture. If the elbow joint remains unstable after fracture fixation, a... Abstract

Cell transplantation, Volume 21, Issue 1, 7 1 2011, Pages 153-173 Myogenic properties of human mesenchymal stem cells derived from three different sources. de la Garza-Rodea AS, van der Velde-van Dijke I, Boersma H, Gonçalves MA, van Bekkum DW, de Vries AA, Knaän-Shanzer S

Mesenchymal stem cells (MSCs) of mammals have been isolated from many tissues and are characterized by their aptitude to differentiate into bone, cartilage, and fat. Differentiation into cells of other lineages like skeletal muscle, tendon/ligament, nervous tissue, and epithelium has been attained with MSCs derived from some tissues. Whether such abilities are shared by MSCs of all tissues is unknown. We therefore compared for three human donors the myogenic properties of MSCs from adipose tiss... Abstract

Toxicology and industrial health, Volume 28, Issue 2, 2 1 2011, Pages 114-121 Influence of naringin on cadmium-induced genomic damage in human lymphocytes in vitro. Yilmaz D, Aydemir NC, Vatan O, Tüzün E, Bilaloglu R

Cadmium is an important toxic environmental heavy metal. Generally, occupational and environmental exposures to cadmium result from heavy metal mining, metallurgy and industrial use and the manufacturing of nickel-cadmium batteries, pigments and plastic stabilizers. Cadmium induces oxidative stress and alters the antioxidant system, resulting in oxidative DNA damage and lipid peroxidation. The effect of naringin, a grapefruit flavonone, on cadmium-induced genomic damage was studied by using an i... Abstract

Neo-coarctation following arterial switch operation (ASO) for transposition of the great arteries (TGA) is a complication that is not regularly described, but may occur. We describe five patients who developed a neo-coarctation after operation. They were diagnosed with TGA, either with or without ventricular septal defect without signs or symptoms of a coarctation. Except for one patient, all patients were reoperated for a neo-coarctation within one year after the ASO. Several explanations are d... Abstract

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 19, Issue 6, 1 1 2011, Pages 297-300 Patent ductus arteriosus in adults - indications and possibilities for closure. van de Sandt FM, Boekholdt SM, Bouma BJ, Groenink M, Backx AP, Koolbergen DR, de Winter RJ, Mulder BJ

Patent ductus arteriosus (PDA) is a rare diagnosis in adults, since symptoms and signs usually occur in infancy and most cases are treated shortly after diagnosis. We present two patients who were first diagnosed with PDA during adulthood. The first case represents a more severe form of PDA, where the need for closure of the PDA is obvious. In the second case the sequelae of the PDA are less clear. In both patients, closure of the PDA (surgically in one case, percutaneously in the other) was suc... Abstract

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 19, Issue 6, 1 1 2011, Pages 290-296 Founder mutations in the Netherlands: familial idiopathic ventricular fibrillation and DPP6. Postema PG, Christiaans I, Hofman N, Alders M, Koopmann TT, Bezzina CR, Loh P, Zeppenfeld K, Volders PG, Wilde AA

In this part of a series on founder mutations in the Netherlands, we review familial idiopathic ventricular fibrillation linked to the DPP6 gene. Familial idiopathic ventricular fibrillation determines an intriguing subset of the inheritable arrhythmia syndromes as there is no recognisable phenotype during cardiological investigation other than ventricular arrhythmias highly associated with sudden cardiac death. Until recently, it was impossible to identify presymptomatic family members at risk... Abstract
