ABSTRACT

Aim
This study evaluated the effect of ultrasonic vibration on the tensile strength required to remove intraradicular post cemented with different materials.

Materials and methods
Bovine teeth were selected, and 7 mm of the cervical root canals were prepared to size 5 Largo drill, the posts were cemented with zinc phosphate, Enforce (resin) or Rely X (glass ionomer). The specimens were divided into six groups (n = 10), according to the following procedures: GI—cementation with zinc phosphate associated with traction force; GII—cementation with zinc phosphate associated with ultrasonic activation and traction force; GIII—cementation with Enforce associated with traction force; GIV—cementation with Enforce associated with ultrasonic activation and traction force; GV—cementation with Rely X associated with traction force; and GVI—cementation with Rely X associated with ultrasonic activation and traction force. The tensile test was conducted using the electromechanical testing machine, the force was determined by a specialized computer program and ultrasonic activation using the Jet Sonic Four Plus (Gnatus) device in 10P.

Results
Concerning to average ranking, GI showed statistically significant difference in comparison with GII and GVI (p < 0.05); there was no statistical difference in GIII and GIV when compared to other groups (p > 0.05).

Conclusion
The ultrasound favored the intraradicular post traction regardless of the employed cement in greater or lesser extent.

Clinical significance
The post removal is a routine practice in the dental office, therefore, new solutions and better alternatives are need to the practitioner. We did not find in the literature many articles referring to this practice. Thus, the results from this study are relevant in the case planning and to promote more treatment options.

Orthognathic Surgery in a Patient with Multiple Sclerosis
Authors: Al-Bazie Saleh A 
Published: October 2015

ABSTRACT

Aim
The aim of this paper was to report a case of orthognathic surgery successfully done in a patient with multiple sclerosis.

Background
Multiple sclerosis (MS) is a chronic, progressive inflammatory disorder of the central nervous system affecting young adults, characterized by lymphocytic infiltration of the brain and spinal cord leading to demyelination and focal axonal damage. Clinically, MS patients present with reversible neurological dysfunction in the early stages, which progresses to irreversible neurological disability and deficit. Oral manifestations of MS include facial numbness or pain, neuralgias, facial paralysis, dysarthria and dysphagia. While dental treatment is not contraindicated in MS patients, it is, however, limited to preventive and supportive dental care.

Case description
A 23-year-old Saudi male patient with a diagnosis of MS since 2008 reported to the oral and maxillofacial surgery (OMFS) department for correction of dentofacial deformity. The patient was under follow-up with the neurology department and was being treated with interferon beta-1a. Following consent from the neurologist and the patient, a Lefort 1 segmental osteotomy was done under general anesthesia. The patient was stable throughout the surgical procedure and during the postoperative period. The patient was discharged upon complete surgical recovery and no acute exacerbations of MS were reported during the perioperative period.

Conclusion
Based on our observations, orthognathic and maxillofacial surgical procedures can be safely carried out in patients with MS, provided a strict perioperative prophylactic regimen for stress reduction and prevention of acute attacks of MS is adhered to.

Clinical significance
Due to the stressful nature of dental treatment and oral and maxillofacial surgical procedures, acute exacerbations of MS are very much likely. Hence, it is imperative that dental and oral surgical practitioners are aware of the manifestations of MS and are able to manage such patients with suitable treatment modifications.

The Great Yeats Debate: Harriet Monroe, Ezra Pound, and Poetry Magazine's First Guarantor's Prize
Authors: O'Dea Dathalinn M. 
Published: October 2015

ABSTRACT
This article addresses how W. B. Yeats and the Irish Revival were interpreted and reimagined for American audiences, particularly in the discursive statements of Harriet Monroe and Ezra Pound in Poetry magazine. Yeats's appearance in the magazine highlights a tension within Poetry between the publication's cosmopolitanism and its investment in regional writing. In keeping with a kind of revivalist logic that valued local cultural production, Poetry in fact demonstrated a provocative engagement with regional modernism. Examining the magazine's regionalism thus allows us to tease apart the complex and interesting ways that the Revival had an afterlife in this important modernist publication.

Legislation: challenges, dilemmas and innovation
Legislation as we know it is a recent phenomenon, and its quality has been under debate for 40 years. It is not surprising or problematic that the place and function of legislation evolve under the influence of societal changes. It is, however, important to change the mechanistic view of legislation. Instead of viewing it as an instrument of policy, we must search for structures and institutions that create room for diversity without breaking the unity of law. In our dealings with inevitable risks and damage to society, rules too often take the place of ethics or professional judgment. Rules are essential, but they should leave room to dissent from them if justified: rules as a point of departure, not rules that must be respected on pain of sanctions.

<p><strong>Introduction:</strong> A benchmarking survey of Canadian health facility libraries was conducted to provide statistical data to support health librarians in the anagement of their libraries. The objectives were to determine the status of<br />hospital libraries in Canada and to evaluate whether libraries meet the 2006 CHLA/ABSC Standards for Library and Information Services in Canadian Healthcare Facilities.</p><p><strong>Methods:</strong> An online survey of 63 questions, with headings of institutional profile, administration, staffing, environment, resources, and services, was created and distributed to 250 heads of hospital libraries and to Canadian library email listservs.</p><p><strong>Results:</strong> Many libraries are meeting some aspects of the Standards for administration and organization, management, traditional promotion, and accessibility. Areas of improvement include services, nontraditional promotion, library environment, and staffing.</p><p><strong>Discussion:</strong> There are no current benchmarking data available for Canadian hospital libraries and there have been many political, economic, and technological changes in past years that have had a substantial impact on libraries. Anecdotal data suggest that librarians have responded to these changes through library closures, mergers, consortial affiliations, and modifications to services. Librarians will be able to use the collected data to compare services, establish best practices, make management decisions, and prepare self-studies for accreditation purposes.</p>
Association between cell wall-related processes and functionally non-annotated factors important for K2 susceptibility
Authors: Lukša Juliana , Vepštaitė Iglė , Servienė Elena 
Published: October 2015

Seventy one genes, previously determined as important for K2 killer protein susceptibility and not annotated in the <i>Saccharomyces Genome Database</i> (SGD), were analyzed by applying computational analysis and investigation of toxin binding efficiency. Links between 44 unknown ORF products and proteins related to cell wall processes were observed. Out of them, 17 single gene knockout mutants express the altered K2 toxin binding phenotype. The comparison of both approaches allowed assignment of 6 previously non-annotated gene products (Slp1, Tda1, Nba1, Ecm3, Ykr046C, and Ybr287W) as functionally associated with cell wall structure maintenance and biogenesis processes, confirming possible involvement in K2 receptor formation.
The Contribution of NGOs in General and Skål International Particularly, in Tourism Development
Authors: Genç Ruhet 
Published: October 2015

AbstractThis paper aims to highlight the importance of non-governmental organisations (NGOs), especially the Skål movement for sustainable tourism. NGOs play a role in developing tourism sustainably by taking into account a community’s attachment, engagement and commitment. NGOs play a vital role in tourism management and development. Skål International which was originally established as an European initiative in the 1930s and has flourished worldwide today is one of the few NGOs that has proven itself as a reliable resource for tourism development. By conducting environmental awareness programs and playing a liaison role between the private sector, communities and the government, Skål develops and establishes standards to be applied in the sector. Other crucial roles include bringing together media representatives, tourism stakeholders, academics and regulators in developing the tourism industry. The involvement of Skål and NGOs in general is beneficial for the tourism industry.
An inversion model based on salinity and remote sensing reflectance for estimating the phytoplankton absorption coefficient in the Saint Lawrence Estuary
Authors: Montes‐Hugo Martin , Xie Huxiang 
Published: October 2015

AbstractThe inversion of individual inherent optical properties (IOPs) is very challenging in optically complex waters and within the violet spectral range (i.e., 380–450 nm) due to the strong light attenuation caused by chromophoric dissolved organic matter, nonalgal particulates, and phytoplankton. Here we present a technique to better discriminate light absorption contributions due to phytoplankton based on a hybrid model (QAA‐hybrid) that combines regional Saint Lawrence System estimates of IOPs derived from a quasi‐analytical algorithm (hereafter QAA‐SLE) and empirical relationships between salinity and IOPs. Preliminary results in the Saint Lawrence System during May 2000 and April 2001 showed that QAA‐hybrid estimates of phytoplankton absorption coefficient at 443 nm have a smaller bias with respect to in situ measurements (root‐mean‐square deviation, RMSD = 0.156) than those derived from QAA‐SLE (RMSD = 0.341). These results were valid for surface waters (i.e., 0–5 m depth) of the lower estuary with a salinity and chlorophyll‐a concentration range of 22–28 psu and 2.1–13.8 mg m−3, respectively.

Published: October 2015

AbstractWith the aim of developing a fully coupled atmosphere‐hydrology model system, the Weather Research and Forecasting (WRF) model was enhanced by integrating a new set of hydrologic physics parameterizations accounting for lateral water flow occurring at the land surface. The WRF‐Hydro modeling system was applied for a 3 year long simulation in the Crati River Basin (Southern Italy), where output from the fully coupled WRF/WRF‐Hydro was compared to that provided by original WRF model. Prior to performing coupled land‐atmosphere simulations, the stand‐alone hydrological model (“uncoupled” WRF‐Hydro) was calibrated through an automated procedure and validated using observed meteorological forcing and streamflow data, achieving a Nash‐Sutcliffe Efficiency value of 0.80 for 1 year of simulation. Precipitation, runoff, soil moisture, deep drainage, and land surface heat fluxes were compared between WRF‐only and WRF/WRF‐Hydro simulations and validated additionally with ground‐based observations, a FLUXNET site, and MODIS‐derived LST. Since the main rain events in the study area are mostly dependent on the interactions between the atmosphere and the surrounding Mediterranean Sea, changes in precipitation between modeling experiments were modest. However, redistribution and reinfiltration of local infiltration excess produced higher soil moisture content, lower overall surface runoff, and higher drainage in the fully coupled model. Higher soil moisture values in WRF/WRF‐Hydro slightly influenced precipitation and also increased latent heat fluxes. Overall, the fully coupled model tended to show better performance with respect to observed precipitation while allowing more water to circulate in the modeled regional water cycle thus, ultimately, modifying long‐term hydrological processes at the land surface.
The consequences of opening the Sunda Strait on the hydrography of the eastern tropical Indian Ocean

Published: October 2015

AbstractThe advection of relatively fresh Java Sea water through the Sunda Strait is presently responsible for the low‐salinity “tongue” in the eastern tropical Indian Ocean with salinities as low as 32‰. The evolution of the hydrologic conditions in the eastern tropical Indian Ocean since the last glacial period, when the Sunda shelf was exposed and any advection via the Sunda Strait was cutoff, and the degree to which these conditions were affected by the Sunda Strait opening are not known. Here we have analyzed two sediment cores (GeoB 10042–1 and GeoB 10043–3) collected from the eastern tropical Indian Ocean off the Sunda Strait that cover the past ~40,000 years. We investigate the magnitude of terrigenous supply, sea surface temperature (SST), and seawater δ18O (δ18Osw) changes related to the sea level‐driven opening of the Sunda Strait. Our new spliced records off the Sunda Strait show that during the last glacial, average SST was cooler and δ18Osw was higher than elsewhere in the eastern tropical Indian Ocean. Seawater δ18O decreased ~0.5‰ after the opening of the Sunda Strait at ~10 kyr B.P. accompanied by an SST increase of 1.7°C. We suggest that fresher sea surface conditions have persisted ever since due to a continuous transport of low‐salinity Java Sea water into the eastern tropical Indian Ocean via the Sunda Strait that additionally increased marine productivity through the concomitant increase in terrigenous supply.
Asymmetric [3+2] Annulation Approach to 3‐Pyrrolines: Concise Total Syntheses of (−)‐Supinidine, (−)‐Isoretronecanol, and (+)‐Elacomine
Authors: Chogii Isaac , Njardarson Jon T. 
Published: October 2015

AbstractAn asymmetric [3+2] annulation reaction to form 3‐pyrroline products is reported. Upon treatment with lithium diisopropylamide, readily available ethyl 4‐bromocrotonate is deprotonated and trapped with Ellman imines selectively at the α‐position to yield enantiopure 3‐pyrroline products. This new method is compatible with aryl, alkyl, and vinyl imines. The efficacy of the method is showcased by short asymmetric total syntheses of (−)‐supinidine, (−)‐isoretronecanol, and (+)‐elacomine. This novel annulation approach also works for an aldehyde, thus providing access to a 2,5‐dihydrofuran product in a single step from simple precursors. By modifying the structure of the carbanion nucleophile, an asymmetric vinylogous aza‐Darzens reaction can be realized.
Tripyrrindione as a Redox‐Active Ligand: Palladium(II) Coordination in Three Redox States

Published: October 2015

AbstractThe tripyrrin‐1,14‐dione scaffold of urinary pigment uroerythrin coordinates divalent palladium as a planar tridentate ligand. Spectroscopic, structural and computational investigations reveal that the tripyrrindione ligand binds as a dianionic radical, and the resulting complex is stable at room temperature. One‐electron oxidation and reduction reactions do not alter the planar coordination sphere of palladium(II) and lead to the isolation of two additional complexes presenting different redox states of the ligand framework. Unaffected by stability problems common to tripyrrolic fragments, the tripyrrindione ligand offers a robust platform for ligand‐based redox chemistry.
Heterophase Photocatalysts from Water‐Soluble Conjugated Polyelectrolytes: An Example of Self‐Initiation under Visible Light

Published: October 2015

AbstractWe herein report a new design route to stable, heterophase photocatalysts, which function as highly dispersible conjugated polymer nanoparticles and porous monoliths under visible light in aqueous medium. They were constructed by attachment of the ionic‐liquid species 1‐alkyl‐3‐vinylimidazolium bromide onto the side chains of a photoactive polymer. The structure configuration allows not only photocatalysis in aqueous environment but also a unique self‐initiation radical cross‐linking process to transform the water‐soluble photoactive polymer into a heterophase system, either as nanoparticles or a porous monolith. High photocatalytic activity and reusability of the heterophase system were demonstrated in the degradation of organic dyes and reduction of CrVI into CrIII in water under visible‐light irradiation.

Published: October 2015

AbstractLatent O‐glycosides, 2‐(2‐propylthiol)benzyl (PTB) glycosides, were converted into the corresponding active glycosyl donors, 2‐(2‐propylsulfinyl)benzyl (PSB) glycosides, by a simple and efficient oxidation. Treatment of the PSB donor and various acceptors with triflic anhydride provided the desired glycosides in good to excellent yields. The leaving group, which was activated by an interrupted Pummerer reaction, can be recycled (PSB‐OH) and regenerated as the precursor (PTB‐OH). A natural hepatoprotective glycoside, leonoside F, was efficiently synthesized in a convergent [3+1] manner with this newly developed method. The present total synthesis also led to a structural revision of this phenylethanoid glycoside.

ABSTRACTModel palm olein natural oil polyols (NOPs) with varying ratios of primary to secondary hydroxyls were synthesized, characterized, and evaluated in reaction kinetics study with isocyanate in formation of polyurethanes. Reaction rate constants and activation energies associated with primary and secondary hydroxyls of NOPs were quantified. The kinetic study in toluene shows that the NOP containing primary hydroxyls have three times higher reaction rate constants in noncatalyzed reaction with 4,4′‐diphenylmethane diisocyanate (4,4′‐MDI) compared to the model NOP containing only secondary hydroxyls, which is associated with higher activation energy of secondary hydroxyls. However, the difference in reaction rate constants of primary and secondary hydroxyls in NOPs diminished in the reactions catalyzed with dibutyltin dilaurate. Bulk polymerization reaction confirms the kinetics results in toluene, showing that the model NOP containing primary hydroxyls reached gel time at a faster rate. Evaluation of elastomers from bulk polymerization shows low degree of phase separation of hard and soft segments for elastomers based on the model NOPs. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

Published: October 2015

Abstract

Background
Although evidence for the benefits of preoperative MRI in breast cancer is lacking, use of MRI is increasing and characterized by large interhospital variation. The aim of the study was to evaluate MRI use and surgical outcomes retrospectively.

Methods
Women with invasive breast cancer (pT1–3) or ductal carcinoma in situ (DCIS), diagnosed in 2011–2013, were selected from the Netherlands Cancer Registry and subdivided into the following groups: invasive cancer, high-grade DCIS, non-palpable cancer, age 40 years or less, and invasive lobular cancer. Associations between preoperative MRI use and initial mastectomy, resection margin after breast-conserving surgery (BCS), re-excision after BCS, and final mastectomy were analysed.

Results
In total, 5514 women were included in the study; 1637 (34·1 per cent) of 4801 women with invasive cancer and 150 (21·0 per cent) of 713 with DCIS had preoperative MRI. Positive resection margins were found in 18·1 per cent women who had MRI and in 15·1 per cent of those who did not (adjusted odds ratio (OR) 1·20, 95 per cent c.i. 1·00 to 1·45), with no differences in subgroups. Re-excision rates were 9·8 per cent in the MRI group and 7·2 per cent in the no-MRI group (adjusted OR 1·33, 1·04 to 1·70), with no differences in subgroups. In the MRI group, 38·8 per cent of patients ultimately underwent mastectomy, compared with 24·2 per cent in the no-MRI group (adjusted OR 2·13, 1·87 to 2·41). This difference was not found for patients aged 40 years or less, or for those diagnosed with lobular cancer.

Conclusion
No subgroup was identified in which preoperative MRI influenced the risk of margin involvement or re-excision rate after BCS. MRI was significantly associated with more extensive surgery, except in patients aged 40 years or less and those with invasive lobular cancer. These results suggest that use of preoperative MRI should be more targeted, and that general, widespread use be discouraged.
Adsorption of N2 and CO2 on Activated Carbon, AlO(OH) Nanoparticles, and AlO(OH) Hollow Spheres

Published: October 2015

AbstractAdsorption behaviors of nitrogen and CO2 on Norit R1 Extra and AlO(OH) nanoparticles and hollow spheres were measured under different temperature and pressure conditions using a magnetic suspension balance. Independent from the substrate investigated, all isotherms increase at lower pressure, reach a maximum, and then decrease with increasing pressure. In addition, selected experimental data were correlated with different model approaches and compared with reliable literature data. In case of CO2 on AlO(OH), capillary condensation was observed at two defined temperatures. The results suggest that the conversion of the liquid into a supercritical adsorbate phase does not take place suddenly.
