Differentiation; research in biological diversity, Volume 76, Issue 7, 21 3 2008, Pages 809-819 Periostin expression by epicardium-derived cells is involved in the development of the atrioventricular valves and fibrous heart skeleton. Lie-Venema H, Eralp I, Markwald RR, van den Akker NM, Wijffels MC, Kolditz DP, van der Laarse A, Schalij MJ, Poelmann RE, Bogers AJ, Gittenberger-de Groot AC

The epicardium is embryologically formed by outgrowth of proepicardial cells over the naked heart tube. Epicardium-derived cells (EPDCs) migrate into the myocardium, contributing to myocardial architecture, valve development, and the coronary vasculature. Defective EPDC formation causes valve malformations, myocardial thinning, and coronary defects. In the atrioventricular (AV) valves and the fibrous heart skeleton isolating atrial from ventricular myocardium, EPDCs colocalize with periostin, a... Abstract

Journal of human evolution, Volume 55, Issue 1, 13 2 2008, Pages 60-74 Functional ecology and evolution of hominoid molar enamel thickness: Pan troglodytes schweinfurthii and Pongo pygmaeus wurmbii. Vogel ER, van Woerden JT, Lucas PW, Utami Atmoko SS, van Schaik CP, Dominy NJ

The divergent molar characteristics of Pan troglodytes and Pongo pygmaeus provide an instructive paradigm for examining the adaptive form-function relationship between molar enamel thickness and food hardness. Although both species exhibit a categorical preference for ripe fruit over other food objects, the thick enamel and crenulated occlusal surface of Pongo molar teeth predict a diet that is more resistant to deformation (hard) and fracture (tough) than the diet of Pan. We confirm these predi... Abstract

The American journal of cardiology, Volume 101, Issue 8, 7 1 2008, Pages 1196-1200 Anemia as an independent predictor of perioperative and long-term cardiovascular outcome in patients scheduled for elective vascular surgery. Dunkelgrun M, Hoeks SE, Welten GM, Vidakovic R, Winkel TA, Schouten O, van Domburg RT, Bax JJ, Kuijper R, Chonchol M, Verhagen HJ, Poldermans D

Anemia is common in patients scheduled for vascular surgery and is a risk factor for adverse cardiac outcome. However, it is unclear whether this is an independent risk factor or an expression of underlying co-morbidities. In total, 1,211 patients (77% men, 68 +/- 11 years of age) were enrolled. Anemia was defined as serum hemoglobin levels Abstract

The Journal of cardiovascular surgery, Volume 49, Issue 1, 1 1 2008, Pages 51-58 Intramuscular or combined intramuscular/intra-arterial administration of bone marrow mononuclear cells: a clinical trial in patients with advanced limb ischemia. Van Tongeren RB, Hamming JF, Fibbe WE, Van Weel V, Frerichs SJ, Stiggelbout AM, Van Bockel JH, Lindeman JH

Aim: Recent evidence indicates that bone marrow mononuclear cells (BMC) promote collateral vessel formation in patients with severe peripheral arterial disease (PAD). However, aspects concerning optimal administration mode, durability and long-term safety require consideration. Combined intra-arterial (IA) plus intramuscular (IM) BMC delivery may be more effective than exclusive intramuscular injections. The aim of this study was to evaluate feasibility, safety and effect of exclusive IM versus... Abstract

International journal of cardiology, Volume 132, Issue 2, 1 1 2008, Pages 257-262 Coronary collaterals improve prognosis in patients with ischemic heart disease. Regieli JJ, Jukema JW, Nathoe HM, Zwinderman AH, Ng S, Grobbee DE, van der Graaf Y, Doevendans PA

Background: The recruitment of coronary collateral vessels results from an endogenous adaptation to ischemic heart disease (IHD). Presence of collaterals may exert protection at the time of acute or chronic obstructive coronary disease. The protective role of collaterals in patients with extensive coronary artery disease however, has been disputed. We examined the effects of coronary collateral circulation on cardiovascular outcomes, with an emphasis on clinical prognostic value and on a putativ... Abstract

Journal of anatomy, Volume 212, Issue 3, 1 1 2008, Pages 286-294 Chronic right ventricular pressure overload results in a hyperplastic rather than a hypertrophic myocardial response. Leeuwenburgh BP, Helbing WA, Wenink AC, Steendijk P, de Jong R, Dreef EJ, Gittenberger-de Groot AC, Baan J, van der Laarse A

Myocardial hyperplasia is generally considered to occur only during fetal development. However, recent evidence suggests that this type of response may also be triggered by cardiac overload after birth. In congenital heart disease, loading conditions are frequently abnormal, thereby affecting ventricular function. We hypothesized that chronic right ventricular pressure overload imposed on neonatal hearts initiates a hyperplastic response in the right ventricular myocardium. To test this, young l... Abstract

Current medical research and opinion, Volume 24, Issue 2, 1 1 2008, Pages 359-364 ApoB/A1 and LDL-C/HDL-C and the prediction of cardiovascular risk in statin-treated patients. Liem AH, van de Woestijne AP, Roeters van Lennep HW, Zwinderman AH, van der Steeg WA, Jukema JW

Background: It is generally accepted that low density lipoprotein cholesterol (LDL-C) or calculated ratios such as LDL-C to high density lipoprotein cholesterol (HDL-C) (LDL-C/HDL-C) are useful predictors of risk of cardiovascular disease in the primary as well as in the secondary prevention setting. However, there is accumulating evidence that the ratio of the corresponding apolipoproteins (apoB/A1) might be superior in some populations. Little is known with regard to the prognostic significanc... Abstract

Cyberpsychology & behavior : the impact of the Internet, multimedia and virtual reality on behavior and society, Volume 11, Issue 1, 1 1 2008, Pages 103-106 Virtual augmented exercise gaming for older adults. Van Schaik P, Blake J, Pernet F, Spears I, Fencott C

This paper details the design, development, and testing of virtual augmented exercise (VAE) gaming for older adults. Three versions of an underwater VAE environment were tested with a sample of 22 healthy adults aged 50 or over. Participants strongly preferred VAE to traditional physical exercise, and adherence rate was 100%. The findings suggest that VAE with puzzles changes or negates the expected negative associations among exercise outcomes. Fitness level was not associated with performance... Abstract

The Annals of thoracic surgery, Volume 85, Issue 2, 1 1 2008, Pages 430-6; discussion 436-7 Restrictive mitral annuloplasty cures ischemic mitral regurgitation and heart failure. Braun J, van de Veire NR, Klautz RJ, Versteegh MI, Holman ER, Westenberg JJ, Boersma E, van der Wall EE, Bax JJ, Dion RA

Background: Restrictive mitral annuloplasty with revascularization is considered the best approach to ischemic mitral regurgitation with heart failure, but late results are controversial. We report late outcome in relation to preoperative left ventricular end-diastolic diameter (LVEDD) cutoff values, previously identified to predict intermediate-term left ventricular reverse remodeling. Methods: One hundred consecutive ischemic mitral regurgitation patients underwent restrictive mitral annulopla... Abstract

The structural control of silicon nanocrystals embedded in amorphous oxide is currently an important technological problem. In this work, an approach is presented to simulate the structural behavior of silicon nanocrystals embedded in amorphous oxide matrix based on simple valence force fields as described by Keating-type potentials. After generating an amorphous silicon-rich-oxide, its evolution towards an embedded nanocrystal is driven by the oxygen diffusion process implemented in the form of... Abstract
