OBJECTIVE The aim of this study was to assess the benefit of using a prophylactic surgical site closed suction drain in pterional craniotomy. MATERIALS AND METHODS A retrospective review was conducted on 607 consecutive patients who underwent a pterional craniotomy for treatment of intracranial anterior circulation aneurysms over a 5-year period. Between January 2000 and December 2004, 607 pa...

Background Postoperative delirium (POD) is a very common complication in operative disciplines, especially in those elderly patients after cardiac surgery. This study aimed to investigate the relationship between C-reactive protein (CRP) and POD in elderly patients undergoing laparoscopic surgery for colon carcinoma. Methods 160 elderly patients scheduled to undergo selective laparoscopic sur...

Establishment of anterior-posterior (a-p) polarity in the Caenorhabditis elegans embryo depends on filamentous (F-) actin. Previously, we isolated an F-actin-binding protein that was enriched in the anterior cortex of the one-cell embryo and was hypothesized to link developmental polarity to the actin cytoskeleton. Here, we identify this protein, POD-1, as a new member of the coronin family of ...

Proper orthogonal decomposition (POD) method has been successfully used in the reduced-order modeling of complex systems. In this paper, we extend the applications of POD method, i.e., combine the classical finite volume element (FVE) method with the POD method to obtain a reduced-order FVE formulation with lower dimensions and sufficiently high accuracy for two-dimensional solute transport pro...

OBJECTIVES The purpose of this study was to investigate the incidence, predictive factors, and effect of post-operative delirium (POD) among patients treated by transcatheter aortic valve replacement (TAVR). BACKGROUND Patients undergoing operations that involve valve replacement appear at higher risk of POD than patients subjected to coronary artery bypass surgery alone. In patients with sev...

Stomatal density of pods and leaves were determined for six commercial snap bean cultivars (Phaseolus vulgaris L. ‘Evergreen’, ‘Hystyle’, Labrador’, ‘Tenderlake’, ‘Top Crop’, and ‘Venture’) grown at three planting dates, in an attempt to find morphological traits that could be related to cultivar differences in pod Ca concentration. Snap beans were planted three times at ≈1-week intervals begin...

This report focuses on improving the stability as well as the approximation properties of Reduced Order Models (ROM) based on Proper Orthogonal Decomposition (POD). The ROM is obtained by seeking a solution belonging to the POD subspace and that at the same time minimizes the Navier-Stokes residuals. We propose a modified ROM that directly incorporates the pressure term in the model. The ROM is...

Zusammenfassung Die vorliegende Masterarbeit behandelt die numerische Lösung linear-quadratischer Optimalsteuerungsprobleme mittels " optimality system POD " (OSPOD) und POD a-posteriori Fehlerschätzer. Ausgangspunkt ist die Modellreduktion mit einem klassischen POD Galerkin Ansatz, wobei die Güte des reduzierten Modells durch den a-posteriori Fehler in der Steuerung sehr gut geschätzt werden k...
