AbstractIn a recent article, we have showed that the nitroxide mediated polymerization of methyl methacrylate was possible up to 80% conversion for reasonable masses Mn = 60,000 g mol−1 when 2,2‐diphenyl‐3‐phenylimino‐2,3‐dihydroindol‐1‐yloxyl nitroxide (DPAIO) was used as control agent. We have claimed that the success of this experiment relied on the absence of H‐transfer reaction both in the alkoxyamine and between alkyl and nitroxyl radical. In this article, the decomposition of 4‐nitrophenyl 2‐(2,2,6,6‐tetramethylpiperidine‐1‐yloxy)‐2‐methylpropionate (1a) and 4‐nitrophenyl 2‐(2,2‐diphenyl‐3‐phenylimino‐2,3‐dihydroindol‐1‐yloxy)‐2‐methylpropanoate (2a) has been studied by 1H NMR in the presence and in the absence (persistent radical effect condition) of scavenger (thiophenol PhSH). At temperature lower than the one used for polymerization, fast and quantitative H‐transfer reaction was observed for 1a whereas no H‐transfer reaction was observed for 2a. The scavenging technique proved for the first time that the H‐transfer was an intermolecular process for 1a. However, the slow side‐reaction of NOC bond homolysis, which did not impede the control of the polymerization but may exert a detrimental effect on the livingness, was observed and quantified for 2a. © 2008 Wiley Periodicals, Inc.

Authors: Montero de Espinosa L. , Ronda J. C. , Galià M. , Cádiz V. 
Published: September 2008

AbstractA novel triglyceride containing α,β‐unsaturated ketone was prepared through photoperoxidation from high oleic sunflower oil by two steps one pot environmentally friendly procedure. This new enone‐containing triglyceride was crosslinked with diaminodiphenylmethane (DDM) via aza‐Michael addition. A kinetic study of the reaction of p‐toluidine with either enone‐containing methyl oleate or epoxidized methyl oleate, as model compounds, allowed us to establish the higher reactivity of the former, thus confirming this curing system as an alternative to amine‐cured epoxidized vegetable oils. The thermal properties of thermosets from enone‐ and epoxy‐containing triglycerides with DDM have been evaluated. © 2008 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 46: 6843–6850, 2008

Published: September 2008

AbstractA commercial norbornyl‐functionalized linseed oil, blended with a bicyclic norbornene‐based crosslinking agent (at loadings ranging from 0 to 50 wt %) undergoes ring‐opening metathesis polymerization with the 1st generation Grubbs' catalyst to form a biorenewable polymer network. Comonomers are characterized, the thermal and mechanical properties of the cured systems are investigated by dynamic mechanical analysis, and thermal decomposition is evaluated by thermogravimetric analysis. The resin is shown to consist of a modified linseed oil and small oligomers of cyclopentadiene. Broad tan δ peaks suggest inhomogeneous phase morphologies, which result in complex crosslinking behaviors. The thermal stability of the polymers increases with increasing crosslinker content. © 2008 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 46: 6851–6860, 2008

Published: September 2008

AbstractA series of poly(aryl ether)s were successfully prepared via aromatic nucleophilic substitution reaction from various bisphenols and a novel bipolar aryl difluoride monomer containing electron‐donor triphenylamine and electron‐acceptor 1,2,4‐triazole moieties. The poly(aryl ether)s exhibited excellent solubility in organic solvents such as dimethylformamide, chloroform, and tetrahydrofuran at room temperature. The poly(aryl ether)s showed high thermal stability with Td10 higher than 500 °C and glass transition temperatures (Tg) higher than 187 °C. The thin films of the poly(aryl ether)s indicated bistable resistive switching behavior with ON/OFF current ratios as high as 103. The switching on and switching off bias voltages of the poly(aryl ether)s were affected by the bisphenol moiety. The good resistive switching behavior of the poly(aryl ether)s made them promising candidates for future nonvolatile memory applications. © 2008 Wiley Periodicals, Inc.

AbstractBACKGROUNDFunctional development of the prostate is governed by stromal mesenchyme induction and epithelial response. Stromal/epithelial signaling can be mediated through direct cell–cell contact and diffusible factors and their cell surface receptors. These inducers are likely secreted or membrane‐associated extracellular proteins. Given the importance of intercellular communication, it is possible that diseases like cancer could arise from a loss of this communication. One approach to gain a molecular understanding of stromal cells is to identify, as a first step, secreted stromal signaling factors. We proposed to do this by comparative analysis between bladder and prostate.METHODSSecreted proteins were identified from cultured normal prostate and bladder stromal mesenchyme cells by glycopeptide‐capture method followed by mass spectrometry. Differences in protein abundance between prostate and bladder were quantified from calculated peptide ion current area (PICA) followed by Western validation. Functional and pathway analyses of the proteins were carried out by Gene Ontology (GO) and Teranode software.RESULTSThis analysis produced a list of 116 prostate and 84 bladder secreted glycoproteins with ProteinProphet probability scores ≥0.9. Stromal proteins upregulated in the prostate include cathepsin L, follistatin‐related protein, neuroendocrine convertase, tumor necrosis factor receptor, and others that are known to be involved in signal transduction, extracellular matrix interaction, differentiation and transport.CONCLUSIONSWe have identified a number of potential proteins for stromal signaling and bladder or prostate differentiation program. The prostate stromal/epithelial signaling may be accomplished through activation of the ECM–receptor interaction, complement and coagulation cascades, focal adhesion and cell adhesion pathways.

Published: September 2008

AbstractManaging patient care records has become an increasingly complex issue with the widespread use of advanced technologies. The vast amount of information for every routine care procedure must be securely processed within different databases. Clinical information systems (CIS) address the need for a computerized approach in managing personal health information. Hospitals and public or private health insurance organizations are continuously upgrading their database and data management systems to more sophisticated architectures. The possible support of today's large patient archives and the flexibility of a CIS in providing up‐to‐date patient information and worldwide doctors' collaboration, has leveraged research on CIS in both the academic and the government domains. At the same time, it has become apparent that patients require more control over their clinical data, these being either the results of clinical examinations or medical histories. Due to the large amount of information that can be found on the Internet and the free access to medical practitioners and hospitals worldwide, patients may choose to communicate their information so as to obtain several expert opinions regarding their conditions. Given the sensitive nature of the information stored and inevitably in transit, security has become an issue of outmost necessity. Numerous EU and US research projects have been launched to address security in CIS (e.g., EUROMED, ISHTAR, and RESHEN), whereas regulatory compliance to acts such as the HIPAA has become an obligation for centers moving to CIS.

AbstractDriven by the emergence of mobile and pervasive computing there is a growing demand for context‐aware software systems that can dynamically adapt to their run‐time environment. We present the results of project MADAM that has delivered a comprehensive solution for the development and operation of context‐aware, self‐adaptive applications. The main contributions of MADAM are (a) a sophisticated middleware that supports the dynamic adaptation of component‐based applications, and (b) an innovative model‐driven development methodology that is based on abstract adaptation models and corresponding model‐to‐code transformations. MADAM has demonstrated the viability of a general, integrated approach to application‐level adaptation. We discuss our experiences with two real‐world case studies that were built using the MADAM approach. Copyright © 2008 John Wiley & Sons, Ltd.

AbstractObjectivesTo describe the grayscale and color Doppler ultrasound findings in women with ovarian hyperthecosis.MethodsIn a retrospective study, we reviewed the findings on ultrasound examination of the ovaries in 10 patients with proven hyperthecosis. Clinical features had been recorded and testosterone levels measured in all cases. The ovaries had been examined using grayscale ultrasound in all patients and color Doppler in six patients. Bilateral stromal hyperthecosis had been pathologically confirmed in all patients.ResultsThe clinical features were polymorphic, with symptoms of virilization in four patients. Type 2 diabetes was present in four patients. Testosterone levels were greater than 2 ng/mL in four patients. On grayscale ultrasound examination, the ovaries were normal in two patients but showed bilateral abnormalities in eight; both ovaries were increased in size in seven patients and had a round shape in two patients, the ovary being both increased in size and round in shape in one of these patients. A very peculiar nodular stromal pattern was observed in two out of 10 patients, while a homogeneous stromal pattern was observed in eight patients. On color Doppler, performed in six patients, no areas of hypervascularization were observed.ConclusionFindings on grayscale ultrasonography and on color Doppler examination, in association with clinical and biological findings, are useful in the diagnosis of ovarian hyperthecosis and in ruling out the presence of an androgen‐secreting tumor.

AbstractObjectiveTo quantify the degree of intrathoracic liver herniation by magnetic resonance imaging (MRI) and evaluate its effect on postnatal survival in fetuses with isolated congenital diaphragmatic hernia (CDH).MethodsForty fetuses that were expectantly managed and that were delivered after 32 weeks' gestation were included in this study. On axial T2 weighted MR images the degree of intrathoracic liver herniation was measured by volumetry, using the xyphoid process and thoracic apex as landmarks. The ratio of the volume of the liver that was herniated into the thoracic cavity to the volume of the thoracic cavity was calculated (LiTR). All the fetuses also underwent lung volumetry, and the ratio of the observed/expected total fetal lung volume (o/e TFLV) was calculated. Regression analysis was used to investigate the effect on survival of side of occurrence of CDH, o/e TFLV, LiTR and gestational age at delivery. Receiver–operating characteristics (ROC) curves were constructed to examine the prediction of survival by o/e TFLV or LiTR alone and o/e TFLV and LiTR together.ResultsUnivariate regression analysis demonstrated that significant predictors of survival were o/e TFLV and LiTR. Multiple regression analysis demonstrated that o/e TFLV and LiTR provided independent prediction of survival. The area under the ROC curve (AUC) for the prediction of postnatal survival from o/e TFLV alone was 0.846 (P < 0.001; SE = 0.062) and the AUC from LiTR alone was 0.875 (P = 0.001; SE = 0.072). The AUC for the prediction of postnatal survival from o/e TFLV and LiTR combined was 0.912 (P < 0.001; SE = 0.045), however it was not statistically significantly different from that of o/e TFLV alone.ConclusionIn expectantly managed CDH fetuses, assessment of LiTR using MRI provided prediction of postnatal survival independently from o/e TFLV.

Mobility enhanced localization in outdoor environments
Authors: Liu Dawei , Lee Moon‐Chuen 
Published: September 2008

AbstractThere is recently an increasing interest in applications based on localization of mobile objects in outdoor environment. Many existing localization solutions rely primarily on a hybrid wireless network/dead reckoning (DR) scheme, as the regular wireless network can hardly estimate a position with satisfactory accuracy in bad channel conditions. However, the DR can involve considerable hardware investments and operating costs, moreover, it suffers from serious error accumulations in motion measurements of the object.To remedy drawbacks of the hybrid scheme, we present a mobility enhanced localization (MEL), in which the mobile object serves as a pseudo beacon. The proposed scheme enables network localization in those areas where traditional wireless networks may not work, and thus, avoids large investments the special hardware cost and error accumulations of DR. We further propose a weighted preprocessing method for classical localization algorithms, since theoretical analysis shows that they fail to consider some boundary conditions. Extensive real world Global Positioning System (GPS) experimental results demonstrate the superiority of the proposed MEL scheme. Copyright © 2008 John Wiley & Sons, Ltd.

AbstractBackgroundThe purpose of this study was to analyze various risk factors and to assess the preoperative risk score, which can predict the prognosis after living donor liver transplantation (LDLT).MethodsFrom February 2002 to August 2007, 84 adult to adult living donor liver transplantation donors and recipients were analyzed. First, the donor, recipient, and intraoperative factors were examined by univariate and multivariate analyses. We then gave a score of one point for each significant marginal factor (total point scores were called “risk score”) and each risk score was examined by univariate analyses.ResultsRecipients with the donor age 50 years or older, Model for End‐Stage Liver Disease (MELD) score (≥21), and hepatitis C virus‐positive status had a significantly poor survival. Recipients between the risk score of 0 vs. scores of 2 + 3 (p < 0.001, log‐rank) and risk score of 1 vs. scores of 2 + 3 (p = 0.003, log‐rank) had significantly different survival.ConclusionsPreoperative assessment of the risk score might help to predict recipient outcomes after living donor liver transplantation.

Published: September 2008

AbstractHerein we characterize the Arabidopsis thaliana AtLOX1 and tomato (Solanum lycopersicum) LOXA proteins as linoleate 9S‐lipoxygenases (9‐LOX), and use the enzymes to test a model that predicts a relationship between substrate binding orientation and product stereochemistry. The cDNAs were heterologously expressed in E. coli and the proteins partially purified by nickel affinity chromatography using a N‐terminal (His)6‐tag. Both enzymes oxygenated linoleic acid almost exclusively to the 9S‐hydroperoxide with turnover numbers of 300–400/s. AtLOX1 showed a broad range of activity over the range pH 5–9 (optimal at pH 6); tomato LOXA also showed optimal activity around pH 5–7 dropping off more sharply at pH 9. Site‐directed mutagenesis of a conserved active site Ala (Ala562 in AtLOX1, Ala 564 in tomato LOXA, and typically conserved as Ala in S‐LOX and Gly in R‐LOX), revealed that substitution with Gly led to the production of a mixture of 9S‐ and 13R‐hydroperoxyoctadecadienoic acids from linoleic acid. To follow up on earlier reports of 9‐LOX metabolism of anandamide (van Zadelhoff et al. Biochem. Biophys. Res. Commun. 248:33–38, 1998), we also tested this substrate with the mutants, which produced predictable shifts in product profile, including a shift from the prominent 11S‐hydroperoxy derivative of wild‐type to include the 15R‐hydroperoxide. These results conform to a model that predicts a head‐first substrate binding orientation for 9S‐LOX. We also found that linoleoyl‐phosphatidylcholine is not a 9S‐LOX substrate, which is consistent with this conclusion.

AbstractLittle information is available concerning whether incorporation of dietary omega‐3 fatty acids into plasma lipids changes during healthy aging. Elderly (74 ± 4 years old) and young (24 ± 2 years old) adults were given a fish oil supplement for 3 weeks that provided 680 mg/day of docosahexaenoic acid and 320 mg/day of eicosapentaenoic acid, followed by a 2 week wash‐out period. Compliance was monitored by spiking the capsules with carbon‐13 glucose, the excretion of which was measured in breath CO2. In response to the supplement, plasma docosahexaenoic acid rose 42% more in the elderly but eicosapentaenoic responded similarly in both groups. Despite raising docosahexaenoic acid intake by five to tenfold, the supplement did not raise plasma free docosahexaenoic acid (% or mg/dL) in either group. We conclude that healthy aging is accompanied by subtle but significant changes in DHA incorporation into plasma lipids.
Reconstruction of elbow flexion in arthrogryposis multiplex congenita type I. Part I: Surgical anatomy and vascular and nerve supply of the pectoralis major muscle as a basis for muscle transfer
Authors: Chomiak Jiri , Dungl Pavel 
Published: September 2008

Purpose The anatomy and neurovascular supply of the pectoralis major muscle was studied in order to establish the safe and functional muscle transfer for the reconstruction of elbow flexion in patients with arthrogryposis multiplex congenita (AMC). Methods Twenty pectoralis major muscles were dissected in 11 adult cadavers. The distribution of the motor end plates was studied in five pectoralis major muscles in foetuses by the detection of esterases. Results The pectoralis major muscle consists of clavicular, manubrial, sternocostal, costal and abdominal parts. Each part has a distinct vascular and nerve supply. The motor nerves arise from the medial and lateral pectoral nerves. The motor end plates are localised in one zone in the clavicular and manubrial parts and in two oblique zones in the distal parts of the muscle. In 15 cases, each of the muscle parts were supplied by one nerve branch. In four cases, six nerves were distinguished and the clavicular part was supplied by two nerves. In one case, four nerves were found, with the clavicular and manubrial parts supplied by one common nerve. Three branches (13 cases) or two arterial branches (seven cases) supplied the muscle, arising from thoracoacromial and lateral thoracic arteries, respectively. The superior branch supplied the clavicular and manubrial parts, whereas the dominant pectoral branch supplied the manubrial, sternocostal and costal parts of the muscle. The inferior branch of the lateral thoracic artery supplied the abdominal part in 13 cases. In seven cases, the inferior branch failed and the abdominal part was supplied from the dominant branch. Conclusion This study presents guidelines for the transfer of the distal parts of the pectoralis major muscle for the reconstruction of elbow flexion. The sternocostal, costal and abdominal parts of the muscle can be released as a unit from the chest wall after dissection between the second and third rib and be transferred to the brachium. They are sufficiently supplied from the dominant pectoral branch of the thoracoacromial artery in all cases and inconstantly from the inferior branch of the lateral thoracic artery and from three motor nerves.
Neoliberal reforms, currency pegs and crisis in Mexico and Argentina
Authors: Felder Ruth , Muñoz Martinez Hepzibah 
Published: September 2008

Abstract
This article argues that exchange rate regimes established by the Mexican peso currency band and the Argentinean Convertibility Plan were key dimensions of the political strategies of neoliberal structural reform through which discipline was imposed on workers and the state. By subordinating wage struggles and state spending to the maintaining of currency pegs, the stabilisation programmes helped to redefine the balances between capital and labour and the conditions of integration of each country within the global economy. This in turn allows for an understanding of the performance of the managed exchange regimes in each country and the states’ divergent economic responses to their exhaustion.
