AbstractPercutaneous closure of perimembranous ventricular septal defects (VSDs) has been feasible, safe, and effective with the new Amplatzer membranous septal occluder. We report further experience with this device with emphasis on morphological aspects of the VSDs and technical issues. Ten patients (median age and weight, 14 years and 34.5 kg, respectively) with volume‐overloaded left ventricles underwent closure under general anesthesia and transesophageal guidance (TEE). The VSD diameter was 7.1 ± 4.0 mm by angiography and 7.8 ± 3.7 mm by TEE. Three patients had defects associated with aneurysm‐like formations (two with multiple exit holes), four had defects shrouded by extensive tricuspid valve tissue, two had defects with little or no tricuspid valve involvement, and one had a right aortic cusp prolapse with trivial aortic regurgitation. Implantation was successful in all patients, although in two the initial device had to be changed for a larger one. Kinkings in the delivery sheath, inability to position the sheath near the left ventricular apex, and device prolapse through the VSD prompted modifications in the standard technique of implantation. Device orientation was excellent except in one case. Nine patients had complete occlusion within 1–3 months. Device‐related aortic or tricuspid insufficiency, arrhythmias, and embolization were not observed. Two patients had slight gradients across the left ventricular outflow tract, normalizing after 3 months. The Amplatzer membranous septal occluder was suitable to close a wide range of perimembranous VSD sizes and morphologies with good short‐term outcomes. Longer follow‐up is required.

AbstractWe report here our initial experience in angiography of gastroepiploic artery (GEA) grafts via a brachial approach using the Yumiko catheter regarding technical aspect. Good‐quality GEA angiography was obtained in 12 (86%) of 14 patients using our technique. GEA graft angiography can be performed using the Yumiko catheter via a brachial approach. This technique may be less stressful for patients receiving coronary catheterization, including GEA graft angiography. Catheter Cardiovasc Interv 2004;61:350–353. © 2004 Wiley‐Liss, Inc.

Published: November 2004

AbstractThe appropriate regimen of platelet inhibitors that should be used in patients with immune thrombocytopenia purpura (ITP; formerly called idiopathic thrombocytopenic purpura) who are undergoing percutaneous coronary intervention is unclear. We report the case of a patient with ITP who underwent two separate coronary interventions. The first involved the use of aspirin and a cutting balloon to treat obstructive disease of the left circumflex. When the patient presented with restenosis, he received eptifibatide, clopidogrel, and an intracoronary stent. He is currently 16 months removed from his second procedure and remains physically active without any anginal symptoms. Percutaneous revascularization in patients with ITP remains a challenge and this therapeutic approach, while ultimately successful in the patient, requires further validation.

Hybridization and Melting Behavior of Peptide Nucleic Acid (PNA) Oligonucleotide Chimeras Conjugated to Gold Nanoparticles
Authors: Murphy Deirdre , Redmond Gareth , de la Torre Beatriz G. , Eritja Ramon 
Published: November 2004

AbstractPeptide nucleic acids (PNA) and PNA–DNA chimeras carrying thiol groups were used for surface functionalization of Au nanoparticles. Conjugation of PNA to citrate‐stabilized Au nanoparticles destabilized the nanoparticles causing them to precipitate. Addition of a tail of glutamic acid to the PNA prevented destabilization of the nanoparticles but resulted in loss of interaction with complementary sequences. Importantly, PNA–DNA chimeras gave stable conjugates with Au nanoparticles. The hybridization and melting properties of complexes formed from chimera–nanoparticle conjugates and oligonucleotide–nanoparticle conjugates are described for the first time. Similar to oligonucleotide–nanoparticle conjugates, conjugates with PNA–DNA chimeras gave sharper and more‐defined melting profiles than those obtained with unmodified oligonucleotides. In addition, mismatch discrimination was found to be more efficient than with unmodified oligonucleotides.
Lipophilicity Measurement by Reversed‐Phase High‐Performance Liquid Chromatography (RP‐HPLC): A Comparison of Two Stationary Phases Based on Retention Mechanisms
Authors: Liu Xiangli , Tanaka Hideji , Yamauchi Aiko , Testa Bernard , Chuman Hiroshi 
Published: November 2004

AbstractThe mechanisms of retention of two recent stationary phases of interest in lipophilicity measurements, namely of the silica‐based Discovery‐RP‐Amide‐C16 phase and the polymer‐based ODP‐50‐4B phase, were assessed and compared. A set of 41 model solutes and drugs with well‐defined solvatochromic parameters were selected to allow a broad distribution of property spaces. The chromatographic results showed that, under the conditions of study, the lipophilicity index log kw obtained with the former stationary phase was more closely related to experimental log Poct values than was log kw obtained with the ODP‐50‐4B phase. Linear solvation/free‐energy relationship (LSER) analyses showed that the retention mechanisms of the two stationary phases are different, retention on the Discovery‐RP‐Amide‐C16 phase and partitioning in octan‐1‐ol/H2O being controlled by the same balance of intermolecular forces (Van der Waals volume Vw, H‐bond acceptor basicity β, and dipolarity/polarizability π*).
Up‐to‐date on parathyroid carcinoma: Analysis of an experience of 19 cases
Authors: Iacobone Maurizio , Lumachi Franco , Favia Gennaro 
Published: November 2004

AbstractBackground and ObjectivesParathyroid carcinoma (PC) is a rare disease; experience with its management is limited. The aim of this retrospective study was to evaluate a relatively large series of patients suffering from PC.MethodsSince 1980, PC was diagnosed in the 4.7% of cases of primary hyperparathyroidism (HPT) (19 patients). Clinical and biochemical features, and surgical outcome were analyzed.ResultsIn patients with PC, the mean serum calcium was 3.34 mmol/L; the tumor size 30.5 mm. Malignancy was never diagnosed preoperatively. Thirty‐two operations were performed; six patients underwent repeated surgery. Recurrence of HPT was observed in 100% of patients. The median disease‐free interval was 15 months (range 2–74 months). Fifteen patients died because of the disease; median survival was 29 months (range 20–146 months). A significant correlation was found between late recurrences and prolonged survival; less advanced age and higher preoperative calcium levels predicted early recurrences.ConclusionsPreoperative diagnosis of PC is difficult. Preoperative severe hypercalcemia should alert the surgeon. En bloc resection of the PC and the adjacent structures is the treatment of choice. Unfortunately, recurrences are common and long‐term survival rate is low. J. Surg. Oncol. 2004;88:223–228. © 2004 Wiley‐Liss, Inc.
Flatness‐Based Trajectory Tracking Control of an Underconstrained Cable Suspension Manipulator
Authors: Heyden Thomas , Woernle Christoph 
Published: November 2004

AbstractCable suspension manipulators support a payload platform in space by several spatially arranged cables with computercontrolled winches. The winches are mounted either fixed or on movable trolleys. Compared to conventional cranes, it is possible to control not only the translational motion of the payload but also its orientation in order to perform, for example, assembly tasks. By this, cable suspension manipulators combine the ability of cranes to support heavy payloads in a large workspace with the dexterity of robot manipulators.The present contribution treats nonlinear trajectory tracking control of cable suspension manipulators that are kinematically undetermined and statically determined. In particular, the cable suspension manipulator Cablev [4] is considered that has been developed at University of Rostock (Fig. 1). Its payload platform is supported by three cables with winches mounted on trolleys that move themselves on a gantry. Thus, the payload platform may perform sway motions with three degrees of freedom while the cable lengths are kept fixed. Applications are, for example, precise handling and assembling large and heavy components on construction sites or on shipyards. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A serological testing algorithm for the diagnosis of primary CMV infection in pregnant women
Authors: Macé M. , Sissoeff L. , Rudent A. , Grangeot‐Keros L. 
Published: November 2004

AbstractObjectivesSerological diagnosis of CMV primary infection is usually based on the detection of specific IgM antibody. However, as the presence of IgM antibody is not always correlated with primary infection, measurement of IgG avidity must be performed. The aim of our study was to evaluate the best procedure for serological diagnosis of CMV primary infection. In other words, is it better to first search for IgM antibody, and, if positive, then measure IgG avidity, or first measure IgG avidity without the detection of IgM antibody?MaterialsCMV‐IgM detection and CMV‐IgG avidity measurement were performed on 310 IgG positive sera from pregnant women.ResultsCMV‐IgM antibody was detected positive for 9 of 310 sera. Using CMV‐IgG avidity index (AI), dating of infection was difficult in 81/310 cases (26%), while it failed in only 3/310 cases using CMV‐IgM plus CMV‐IgG AI.ConclusionThe diagnosis of primary CMV infection can be based on the detection of CMV‐IgM antibody first and then on the measurement of CMV‐IgG AI.

AbstractObjectiveTo investigate outcomes of ultrasound investigations (US) and invasive diagnostic procedures in cases of congenital malformations (CM), and to compare the use of invasive prenatal test techniques (amniocentesis (AC) versus chorionic villus sampling (CVS)) among European populations.DesignAnalysis of data from population‐based registries of CM.Subjects25 400 cases of CM recorded by 14 EUROCAT registries covering a total population of 1 013 352 births 1995–99.ResultsUS were performed in 91% of cases, and positively detected CM in 35% of cases. AC was performed in 24% of the cases and CVS in 3% of cases. Thirty‐eight percent of invasive tests gave positive results. Fifty‐two percent of cases with maternal age ≥ 35 years had an invasive test performed compared to 20% of cases with younger mothers.Considerable variation was found between registries in the uptake rate of invasive tests in cases with older maternal age and on the use of invasive tests with only four regions employing CVS techniques in at least a third of the cases having invasive tests. For chromosomal anomalies US gave positive results in 46% of cases with maternal age < 35 years with US performed and in 36% of cases with maternal age ≥ 35 years with US performed.ConclusionPrenatal US was performed in 91% of all pregnancies with CM but the test was only positive in a third of the cases. There was large regional variation in the uptake rate of invasive tests with maternal age of 35 years or more. For every CVS carried out there were nine AC tests. US is an important tool in the prenatal diagnosis of chromosomal anomalies in Europe. Copyright © 2004 John Wiley & Sons, Ltd.
Cyclic deformation behavior of an epoxy polymer. Part I: Experimental investigation
Authors: Shen Xinghe , Xia Zihui , Ellyin Fernand 
Published: November 2004

AbstractA series of uniaxial cyclic tests were carried out on solid cylindrical specimens of an epoxy resin, Epon 826/Epi‐Cure Curing Agent 9551. The focus of the study was to investigate time‐dependent viscoelastic behavior of this thermosetting polymer material under cyclic loading and to develop a constitutive model with the capabilities to simulate the observed deformation response. The tests include stress‐controlled or strain‐controlled cyclic loading with/without mean stress or mean strain at various amplitudes and loading rates. It was found that the cyclic stress‐strain response of this material is amplitude‐dependent and rate‐dependent, and the response to axial tension is different from that in compression. The stress‐strain loops exhibit more pronounced nonlinearity with high amplitudes or low loading rates. For stress‐controlled cyclic loading with mean stress, ratcheting strain is accumulated, which is of viscoelastic nature, and this is confirmed by its full recovery after load removal. For strain‐controlled cyclic loading with mean strain, the mean stress relaxation occurs, which contributes to the observed longer life in comparison to the stress‐controlled cyclic loading with mean stress.

Published: November 2004

AbstractThe extrusion (single‐screw) characteristics of four high‐molecular‐weight, broad‐molecular‐weight‐distribution (MWD) polyethylene resins are discussed with an emphasis on the output rate. Despite the high molecular weights of the subject polyethylenes, their broad MWD (Mw/Mn range: 10 to 50) does not limit the pressure and torque developed during extrusion. However, the specific output of the four polymers was quite varied. First, the dynamics of the solids conveying section were examined with the highest‐molecular‐weight polyethylene exhibiting lower solids‐conveying rate than the other three. Further, a simple and quick method to evaluate the relative solids‐conveying efficiencies for various polyethylenes is presented. Finally, the dependence of the specific output on the melt rheology of the polymers is also addressed; specifically, the shear‐thinning extent of the melt in the metering section was found to influence output rate. The unique and counterintuitive temperature‐dependence of the shear‐thinning character for one of the four polymers will also be addressed in relation to its extrusion characteristics. Polym. Eng.

Temperature control in injection molding. Part II: Controller design, simulation, and implementation
Authors: Dubay Rickey , Diduch Chris , Li Wan Gui 
Published: November 2004

AbstractThis paper presents a new approach for temperature control of an injection molding machine (IMM) that uses a model predictive control (MPC) strategy. The control system consists of a number of single‐input‐single‐output model predictive controllers, each associated with a particular temperature zone. What distinguishes this approach from others is how the MPC strategy exploits knowledge of temperature interaction between adjacent zones and the effects of back pressure, to develop individual temperature controllers for each zone. This is achieved by decoupling the interaction between zones. The new thermal controller was simulated and implemented with good results on a 150‐tonne IMM using a series of comparative experiments.

Published: November 2004

AbstractA poly(methyl methacrylate)‐intercalated graphite oxide/poly(methyl methacrylate) nanocomposite was prepared by emulsion polymerization of methyl methacrylate in the presence of graphite oxide (GO). GO was synthesized by the oxidization of natural graphite powder with KMnO4 in concentrated sulfuric acid. The functional groups and microstructure of the oxidized graphite and the composite were carefully characterized by use of X‐ray diffraction, infrared, transmission electron microscopy, and elemental analysis. The electrical conductivity and mechanical properties were also measured. Polym. Eng. Sci. 44:2335–2339, 2004. © 2004 Society of Plastics Engineers.
Florale Transparenz: Das neue Dach über dem Innenhof der IHK in Würzburg
Authors: Schöne Lutz 
Published: November 2004

AbstractAnwendungen von einlagigen, mechanisch vorgespannten und seilgestützten ETFE‐Folien als Wetterhäute im Hochbau sind kaum bekannt – es gibt, wenn überhaupt, wohl erst sehr wenige Konstruktionen dieser Art. Das Interesse verdienen sie vor allem aufgrund der Verbindung der besonderen physikalischen Eigenschaften der Folie (Durchlässigkeit für ein sehr weites Wellenlängenspektrum, geringes Gewicht, “selbstreinigend”) mit den bekannten Möglichkeiten und Eigenschaften mechanisch gespannter Membranen.Die beschriebenen Trichterschirme stehen hierfür exemplarisch: Zum einen kann die antiklastische Fläche der Trichter nur über eine mechanische Vorspannung realisiert werden, zum anderen wird für den Innenhof und die angrenzenden Büroräume eine maximale Bandbreite des natürlichen Lichtes bereitgestellt.Die architektonische Qualität erreicht die Konstruktion im Zusammenspiel von Folie, Seilen und Stahl. Die Stützen sind so schlank wie möglich gehalten – geplant mit aufwendigem ingeniösem Handwerkszeug; die Fügungen möglichst einfach und klar – meist einfache Lasche‐Bolzen‐Verbindungen; Folie und Seile kaum sichtbar und die Funktion zuverlässig und robust.
The differential association of intimate partner physical, sexual, psychological, and stalking violence and posttraumatic stress symptoms in a nationally representative sample of women
Authors: Basile Kathleen C. , Arias Ileana , Desai Sujata , Thompson Martie P. 
Published: November 2004

AbstractThis study examines whether experiences with four different types of intimate partner violence (IPV) increase risk for posttraumatic stress disorder (PTSD) symptoms. We examined impacts of physical, sexual, psychological, and stalking victimization by a current partner on PTSD symptoms, the extent to which each type of IPV accounted for significant variance in PTSD symptoms when controlling for other forms, and the increase in PTSD symptoms from multiple forms of IPV. Findings reveal that all types of violence were associated with increased PTSD symptoms. When controlling for other types of violence, physical, psychological, and stalking violence were still associated with PTSD symptoms. There was evidence of a dose response in which the more types of violence experienced, the more PTSD symptoms.
Shame‐proneness as a diathesis for dissociation in women with histories of childhood sexual abuse
Authors: Talbot Jean A. , Talbot Nancy L. , Tu Xin 
Published: November 2004

AbstractThis study examined whether shame‐proneness is associated with dissociation among abused women. Participants were 99 hospitalized women with and without reported histories of childhood sexual abuse. Hypotheses were that childhood sexual abuse and shame‐proneness would each be associated with dissociation, and that the relationship between sexual abuse and dissociation would be greater among women with higher shame‐proneness. Multiple regression analysis indicated that shame‐proneness was independently related to dissociation, but childhood sexual abuse was not. As predicted, the combination of shame‐proneness and childhood sexual abuse was associated with dissociation.

Published: November 2004

The antihyperalgesic effect of pentoxifylline was investigated in three experimental pain models.
Pentoxifylline (0.5–1.6 mg kg−1) given 30 min before the stimulus significantly inhibited the writhing response induced by the intraperitoneal (i.p.) administration of either acetic acid (−90%) or zymosan (−83%), but not that of iloprost, in mice, as well as the zymosan‐induced articular hyperalgesia in the zymosan arthritis in rats (−50%).
Pentoxifylline also inhibited the mechanical hypernociception in rats induced by the intraplantar injection of either carrageenin (−81%), bradykinin (−56%) or tumor necrosis factor α (TNF‐α; −46%), but not that induced by interleukin‐1β (IL‐1β) or prostaglandin E2 (PGE2).
Pentoxifylline did not inhibit the nociceptive response in the hot plate test in mice. Further, the antinociceptive effect of pentoxifylline in the writhing test in mice and the zymosan‐induced articular hyperalgesia were not reversed by the coadministration of the opioid receptor antagonist naloxone. Thus, pentoxifylline antinociceptive effect is probably not mediated at a central level.
Pentoxifylline significantly reduced TNF‐α (−43%) and IL‐1β (−42%) concentrations in the joint exudates of rats stimulated by intra‐articular injection of zymosan and the production of both cytokines (−66 and −86%, respectively) by mouse peritoneal macrophages stimulated in vivo with zymosan as well as the expression of TNF‐α at the tissue level in carrageenin‐injected rat paws.
In conclusion, the antinociceptive activity of pentoxifylline is associated with the inhibition of the release of both TNF‐α and IL‐1β.
