Aminimide derived from benzoylformic acid ester as photolatent base/radical initiator
Authors: Kirino Manabu , Tomita Ikuyoshi 
Published: January 2012

AbstractAn aminimide possessing a benzoyl substituent, 1,1‐dimethyl‐1‐(2‐hydroxypropyl)amine benzoylformimide (BFI), proved to serve as an excellent photobase catalyst. BFI decomposes smoothly by the UV irradiation to give products containing tertiary amines. The effective nature of BFI as a photo/thermal dual‐base catalyst was convinced by the thermal and photoinduced polymerization of epoxide/thiol system. Based on the facts that the mixture of BFI and epoxide/thiol exhibit a long pot life in dark and that it undergoes smooth polymerization by UV irradiation and heating, it was supported that BFI serves as an efficient photo/thermal latent dual‐base catalysts. It was also found that BFI initiates the free radical polymerization of vinyl monomers such as 2‐hydroxylethyl methacrylate (HEMA) under the UV irradiation while the mixture of BFI and HEMA also exhibit a long pot life in dark, indicating the excellent ability of BFI as a photoradical initiator. © 2012 Wiley Periodicals, Inc.

Published: January 2012

AbstractA novel two‐phase polymer nanocomposite film comprising of polyvinylidene fluoride (PVDF) and nanocrystalline (∼90 nm) semiconducting multiferroic BiFeO3(BFO) have been fabricated by hot‐molding technique. Such flexible thick nanocomposite films, semicrystalline in nature, exhibited extraordinarily high effective dielectric permittivity εeff∼ 103(compared with that of pure PVDF) near the low percolation threshold (fc= 0.12) at room temperature (RT) and the films also possessed low dielectric loss (∼0.18). The polarization‐electric field (P‐E) hysteresis loops are displayed at RT, which indicate ferroelectric like behavior of PVDF still persists in the percolative nanocomposite. There is also large increase of remanent polarization of BFO in the composite indicating improvement of the multiferroic behavior of BFO embedded in the PVDF polymer. The sample also indicates good fatigue endurance. Formation of microcapacitors and percolative behavior are correlated to explain the obtained results based on the special geometry of the BFO nanofillers. © 2012 Wiley Periodicals, Inc.

Published: January 2012

AbstractBackgroundAnal cancer rates are increasing in HIV‐infected men. Screening programmes similar to prostate and cervical cancer have been recommended to reduce morbidity and mortality. Research shows that screening processes have psychological consequences that need to be considered. Limited investigation of the psychological impact of anal cancer screening has been conducted.MethodsA prospective longitudinal survey of 291 men was conducted at three time points over 14 weeks at a public HIV clinic in Sydney, Australia. Self‐report questionnaires measuring worry, distress, depression, anxiety, stress and health‐related quality of life (SF‐12) were collected.ResultsThose who had a biopsy recommended were significantly more worried about anal cancer, rated their anal health worse and were less optimistic about their future health than the control group who needed no further medical investigation. The group receiving high grade histology results remained worried about anal cancer at time 3. We found no evidence that general anxiety, depression or quality of life was significantly affected by the process.ConclusionsAnal cancer specific worry increases throughout the screening process. Clear communication prior to procedures about the procedure itself, potential adverse events, the recovery process and non‐technical explanations of results should be implemented in anal screening programmes.Copyright © 2012 John Wiley & Sons, Ltd.
Sorption and dissipation of aged metolachlor residues in eroded and rehabilitated soils
Authors: Cabrera Alegría , Papiernik Sharon K , Koskinen William C , Rice Pamela J 
Published: January 2012

AbstractBACKGROUND: Sorption and dissipation of aged metolachlor were characterized in rehabilitated and eroded prairie soils using sequential batch slurry (conventional) and accelerated solvent extraction (ASE).RESULTS: In spite of an almost twofold difference in soil organic carbon (OC) content, S‐metolachlor sorption coefficients (Kd) and dissipation rates (DT50) were the same in soils from different landscape positions within an eroded landform. Soil was moved within the landform to increase productivity. In areas receiving topsoil addition, S‐metolachlor Kd was higher and DT50 was longer than in eroded areas. The efficiency of extraction was higher for ASE than for conventional extractions. No consistent aging effect on Kd was observed. Mineralization in 8 weeks accounted for < 10% of the applied metolachlor.CONCLUSION: The results of this laboratory study support a field dissipation study. Both showed that S‐metolachlor has the same retention and dissipation rate throughout an eroded landform, which was not expected owing to the large variability in soil properties, including OC concentrations. Altering soil properties by adding topsoil increased metolachlor sorption and persistence. The method of extraction (conventional versus ASE) affected calculated sorption coefficients and dissipation rates. In all cases, groundwater ubiquity scores (GUSs) categorized metolachlor as having intermediate mobility. Published 2012 by John Wiley & Sons, Ltd.

Published: January 2012

AbstractBACKGROUND: Predatory mites (Amblyseius swirskii Athias‐Henriot, Typhlodromips montdorensis Schicha, Neoseiulus cucumeris (Oudemans) and Iphiseius degenerans Berlese) were investigated for their potential to act as control agents for Thrips palmi Karny. Prey consumption rates and compatibility with pesticides were assessed.RESULTS: Second‐instar larvae were the preferred life stage. Typhlodromips montdorensis consumed the most larvae (2.8) and also an average of 1.2 adult T. palmi per 5 day period. Both 24 and 48 h assessments following application of abamectin, spinosad and imazalil demonstrated mortality of predatory mites (across all species), which was significantly higher than with the other treatments (P < 0.001). Spraying with pymetrozine did not provide any increased mortality when compared with the water control. Application of thiacloprid proved detrimental only to I. degenerans. Following indirect exposure of predatory mites to pymetrozine and imazalil, no significant differences in mite mortality were obtained. Indirect exposure to spinosad was identified as the most detrimental treatment (P < 0.001) to all mites. Abamectin also proved detrimental, with only T. montdorensis showing any potential tolerance.CONCLUSION: All predatory mites investigated offer potential for controlling T. palmi. Compatibility with chemicals varied between the mites. The potential of incorporating the mites into eradication strategies for T. palmi is discussed. Copyright © 2012 Society of Chemical Industry
Respiratory syncytial virus infection and immunity

Published: January 2012

SUMMARYRespiratory syncytial virus (RSV) is the leading cause for childhood hospitalization and respiratory distress, being recognized as a major health and economic burden worldwide. RSV can exploit host immunity and cause a strong inflammatory response that leads to lung damage and virus dissemination. Unfortunately, the immune response elicited by RSV normally fails to protect against subsequent exposures to the virus. Despite intense research during the 50 years after the discovery of RSV, scientists are just beginning to understand the mechanisms contributing to pathology and to the inadequate immune response shown by susceptible individuals. Here, we discuss some of the most important advances made in this field that could lead to the development of new prophylactic tools. Copyright © 2012 John Wiley & Sons, Ltd.
On supervised mining of dynamic content‐based networks1
Authors: Aggarwal Charu C. , Li Nan 
Published: January 2012

AbstractIn recent years, a large amount of information has become available online in the form of web documents, social networks, or blogs. Such networks are large, heterogeneous, and often contain a huge number of links. This linkage structure encodes rich structural information about the topical behavior of the network. Such networks are often dynamic and evolve rapidly over time. Much of the work in the literature has focused on classification either with purely text behavior or with purely linkage behavior. Furthermore, the work in the literature is mostly designed for static networks. However, a given network may be quite diverse, and the use of either content or structure could be more or less effective in different parts of the network. In this paper, we examine the problem of node classification in dynamic information networks with both text content and links. Our techniques use a random walk approach in conjunction with the content of the network to facilitate an effective classification process. Our approach is dynamic, and can be applied to networks which are updated incrementally. Our results suggest that an approach based on both content and links is extremely robust and effective. We also present methods to perform supervised keyword‐based clustering of nodes using this approach. We present experimental results illustrating the effectiveness and efficiency of our classification approach. We also show that the approach is able to find effective and coherent clusters. © 2012 Wiley Periodicals, Inc. Statistical Analysis and Data Mining 5: 16–34, 2012
Improving safety and availability of complex systems by using an integrated design approach in development
Authors: Bachmann Volker , Messnarz Richard 
Published: January 2012

ABSTRACTWithin the last 5 years the need for a system development and a process that describes this development became more and more obvious. The number of software and electronic engineers rose even in companies that were traditionally working in the field of pure mechanics. The ISO standard 15504 was consequently expanded from the software to the system. Nevertheless, even 5 years after this change, there is nearly no subsystem mechanics completely described in the same tool as the subsystems electronics and software. This break within the tool chain is the tip of an iceberg reaching all the way down to the lived processes in development.This paper tries to give a solution that was worked out in a group of integrated designers that developed a program for the European Certification and Qualification Association. It shows an example that was tested in an industry project to reach level two, according to the Automotive SPICE standard, on system level in a customer assessment. It shows how to bring together standards that are used in electronics, software, and mechanics to find an integrated design approach to improve safety and availability of systems composed of these parts. Namely, this is the IEC 61508 asking for a risk analysis, which again finds entrance into the failure mode and effects analysis (FMEA) that is a commonly known tool in mechanical development. The FMEA again has an interface to the ISO 15504, which is described here as well.An integrated design is the outcome of this process by using the tools mentioned and bringing them together properly.

Published: January 2012

AbstractInositol polyphosphate phosphatase 4 A (INPP4A), a phosphoinositides phosphatase, is highly expressed in the central nervous system and plays a role in glutamate excitotoxicity and cell proliferation. Our aim was to investigate the expression of INPP4A in patients with temporal lobe epilepsy (TLE) and in a rat model of epilepsy. We assessed the expression of INPP4A in the temporal neocortex from 20 TLE patients. The result showed that INPP4A expression was significantly lower in TLE patients than in controls. To validate the results found in TLE patients, we assessed the expression of INPP4A in rat model. Rat epilepsy was induced by lithium‐pilocarpine. Expression of INPP4A of rat models was assessed by immunohistochemistry, immunofluorescence, and Western blotting. INPP4A was expressed in the membrane and cytoplasm of neurons. In the hippocampus and neocortex of epileptic rats, INPP4A expression was first downregulated at the 24 h after seizures and maintained decreased levels at 72 h, 7 days, 14 days, 30 days, and 60 days, respectively. These results suggest that a decreased expression of INPP4A in the brain may be associated with TLE. Synapse, 2012. © 2012 Wiley Periodicals, Inc.
Longitudinal and parallel monitoring of neuroinflammation and neurodegeneration in a 6‐hydroxydopamine rat model of Parkinson's disease

Published: January 2012

AbstractAs neuroinflammatory processes are involved in the pathogenesis of Parkinson's disease (PD), we achieved the longitudinal evaluation of them in parallel with the modifications of dopaminergic function at several time‐points after 6‐hydroxydopamine (6‐OHDA) lesion in the rat mimicking an early stage of PD. After unilateral intrastriatal 6‐OHDA administration, we quantified the temporal evolution of the 18 kDa translocator protein (TSPO), TH‐immunoreactivity and dopamine transporters in the striatum and substantia nigra pars compacta (SNc) from 3‐ to 56‐days postlesion (dpl). Increased binding of TSPO ligands used, i.e., [3H]PK11195 and [125I]CLINDE, was observed in the lesioned striatum at 3, 7, and 14 dpl, followed by a progressive return to the basal level at 56 dpl. The binding profile in the SNc showed progressive binding beginning at 3 dpl, peaking at 14 dpl, and progressively decreasing until 56 dpl. In this model, the neuroinflammatory and neurodegenerative processes occurred concomitantly. The transitory occurrence of microglial activation could be involved in the lasting installation of dopaminergic neuron loss. Synapse, 2012. © 2012 Wiley Periodicals, Inc.
Exploiting resource heterogeneity in delay‐tolerant networks
Authors: Sandulescu Gabriel , Schaffer Péter , Nadjm‐Tehrani Simin 
Published: January 2012

ABSTRACTRouting in delay and disruption‐tolerant networks (DTNs) relies on intermediary nodes, called custodians, to deliver messages to destination. However, nodes usually differ significantly in terms of available resources: energy, buffer space and bandwidth. Routing algorithms need to make the most efficient use of custodian resources while also making sure those in limited supply are not exhausted. This paper proposes a distributed scheme for calculating resources available in node vicinity as a tool to support meaningful routing decisions. A generic model is developed first and is then applied to individual network assets. The model is based on a sparse network, where resources are potentially not uniformly distributed. It uses recent encounters to estimate resource availability in node vicinity. It is shown that a store‐carry‐forward scheme may benefit from accessing vicinity resource estimates. This knowledge allows nodes to implement meaningful custodian election and queue management strategies, approached here from a holistic perspective. It is demonstrated that routing protocols not only use up fewer resources overall but also consume resources preferentially from nodes with higher resource levels, sparing nodes with limited supplies. As a result, disparities in available resources across the node population are significantly reduced, and nodes are less likely to leave the network as a consequence of resource depletion.

“If We're Going to Change Things, It Has to Be Systemic:” Systems Change in Children's Mental Health
Authors: Hodges Sharon , Ferreira Kathleen , Israel Nathaniel 
Published: January 2012

AbstractCommunities that undertake systems change in accordance with the system of care philosophy commit to creating new systems entities for children and adolescents with serious emotional disturbance. These new entities are values‐based, voluntary, and cross‐agency alliances that include formal child‐serving entities, youth, and families. Describing the scope and intent of one such implementation of systems of care, a mental health administrator commented, “If we're going to change things, it has to be systemic” (B. Baxter, personal communication, December 2, 2005). This paper explores the concept of “systemic” in the context of systems of care. Systems theory is used to understand strategies of purposeful systems change undertaken by stakeholders in established system of care communities. The paper presents a conceptual model of systems change for systems of care that is grounded in data from a national study of system of care implementation (Research and Training Center for Children's Mental Health in Case Studies of system implementation: Holistic approaches to studying community‐based systems of care: Study 2, University of South Florida, Louis de la Parte Florida Mental Health Institute, Research and Training Center for Children's Mental Health, Tampa, FL, 2004). The model is based on Soft Systems Methodology, an application of systems theory developed to facilitate practical action around systems change in human systems (Checkland in Systems thinking, systems practice, Wiley, Chichester, 1999). The implications of these findings to real world actions associated with systems change in systems of care are discussed.
A Systematic Review of Peer Review for Scientific Manuscripts
Authors: Larson Bradley P. , Chung Kevin C. 
Published: January 2012

Background The usefulness of peer review has been expressed as a method to improve the quality of published work. However, there has been a lack of systematic reviews to date to highlight the essential themes of the peer-review process. Methods We performed a search of the English language literature published prior to October 2011 using PubMed to identify articles regarding peer review. Inclusion and exclusion criteria were developed a priori. Data were extracted and then analyzed for the prevalence of peer-review themes contained within the literature. Results Of the 941 articles found during our original literature search, 37 were selected for review. The majority were commentary/editorial articles. The themes in our search included the structure and process of the peer-review system, the criteria for papers, ethics, and the different forms of the peer-review process. Conclusions The criteria for submission will vary, but our systematic review provides a comprehensive overview of what reviewers expect from authors. Our systematic review also highlighted ethical considerations for both authors and reviewers during the peer-review process. Although the topic of peer review is expansive and its process may vary from journal to journal, the understanding of the themes outlined in this paper will help authors recognize how to write a more successful paper. Also, more research must be carried out to establish the efficacy of the different styles of peer review, and it would be presumptuous to draw conclusions until further research is established.
Development and Validation of a UK-Specific Prostate Cancer Staging Predictive Model: UK Prostate Cancer Tables
Authors: Lam Thomas B.L. , Regnier-Coudert Olivier , McCall John , McClinton Sam 
Published: January 2012

Objectives: To construct new prostate cancer staging lookup tables based on a dataset collated by the British Association of Urological Surgeons (BAUS) and to validate them and compare their predictive power with Partin tables. Patients and methods: Complete data on 1701 patients was collated between 1999 and 2008 across 57 UK centres. Lookup tables were created for prediction of pathological stage (PS) using PSA level, biopsy Gleason score (GS) and clinical stage, replicating Partin's original approach. Tables were generated using logistic regression (LR) and bootstrap resampling methods and were internally validated and externally validated using concordance indices (CI) and area under the receiver operating characteristic curve (AUROC) respectively. Results: The CI and AUROC analyses indicate that Partin tables performed poorly on UK data in comparison with US data. The UK prostate cancer tables performed better than Partin tables but the predictive power of all models was relatively poor. Conclusion: The study shows that the predictive power of Partin tables is reduced when applied to the UK population. Models generated using LR methodology have fundamental limitations, and we suggest alternative modelling methods such as Bayesian networks.
Imagining thin: Why vanity sizing works
Authors: Aydinoğlu Nilüfer Z. , Krishna Aradhna 
Published: January 2012

AbstractVanity sizing, the practice of clothing manufacturers, whereby smaller size labels are used on clothes than what the clothes actually are, has become very common. Apparently, it helps sell clothes—women prefer small size clothing labels to large ones. We propose and demonstrate that smaller size labels evoke more positive self‐related mental imagery. Thus, consumers imagine themselves more positively (thinner) with a vanity sized size‐6 pant versus a size‐8 pant. We also show that appearance self‐esteem moderates the (mediating) effect of imagery on vanity sizing effectiveness—while vanity sizing evokes more positive mental imagery for both low and high appearance self‐esteem individuals, the effect of the positive imagery on clothing preference is significant (only) for people with low appearance self‐esteem, supported by the theory of compensatory self‐enhancement.Our suggestion of simple marketing communications affecting valence of imagery and consequent product evaluation have implications for many other marketing domains.
Identification of miR414 and Expression Analysis of Conserved miRNAs from Stevia Rebaudiana
Authors: Guleria Praveen , Yadav Sudesh Kumar 
Published: January 2012

Abstract
MicroRNAs (miRNAs) usually contain 19-24 nucleotides and have been identified as important eukaryotic gene regulators. Applications of various computational approaches have simplified the task by predicting miRNAs from available sequence data sources. In this study, we identified a conserved miR414 from a computational analysis of EST sequence data available from Stevia rebaudiana. In addition, we also identified six conserved miRNAs namely miR169, miR319, miR414, miR164, miR167 and miR398 using stem-loop RT-PCR analysis. Hence, miR414 was commonly identified using both methods. The expression analysis of these miRNAs documented their roles in growth and development of Stevia. Furthermore, the detected miRNAs were found to target genes involved in plant growth, development, metabolism and signal transduction. This is the first study reporting these conserved miRNAs and their expression in Stevia.
