Abstract
The degradation of methyl tert-butyl ether (MTBE) was investigated in the aqueous solution of coated ZnO onto magnetite nanoparticale based on an advanced photocatalytic oxidation process. The photocatalysts were synthesized by coating of ZnO onto magnetite using precipitation method. The sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibration sample magnetometer (VSM). Besides, specific surface area was also determined by BET method. The four effective factors including pH of the reaction mixture, Fe3O4/ZnO magnetic nanoparticles concentration, initial MTBE concentration and molar ratio of [H2O2]/ [MTBE] were optimized using response surface modeling (RSM). Using the four-factor-three-level Box–Behnken design, 29 runs were designed considering the effective ranges of the influential factors. The optimized values for the operational parameters under the respective constraints were obtained at PH of 7.2, Fe3O4/ZnO concentration of 1.78 g/L, initial MTBE concentration of 89.14 mg/L and [H2O2]/ [MTBE] molar ratio of 2.33. Moreover, kinetics of MTBE degradation was determined under optimum condition. The study about core/shell magnetic nanoparticles (MNPs) recycling were also carried out and after about four times, the percentage of the photocatalytic degradation was about 70%.

Abstract
Background
This randomized controlled trial investigated the role of omega-3 supplementation on C5L2 gene expression in type 2 diabetics.

Methods
Subjects in the omega-3 group received 4 g omega-3 per day and subjects in the placebo group took four capsules of placebo per day for 10 weeks. Gene expression was measured by RT- PCR at the beginning and end of the study.

Results
The results of this study show depletion in the omega-3 group, but the mean difference between two groups was not significant.

Conclusions
Understanding the effect of the omega-3 pathway could contribute to targeting treatment of diabetes and its comorbidities.

Abstract
Background
Biopterins have a crucial role in the function of nitric oxide synthase, uncoupling of the enzyme leads to endothelial dysfunction and vascular damage, The aim of this study was to evaluate the relationship between the levels of biopterins with carotid intima-media thickness (CIMT) in hypertensive type-2 diabetic patients.

Methods
We studied 30 hypertensive type-2 diabetic patients and 30 normotensive non-diabetic age-matched subjects, in whom biopterins levels were measured by reverse phase high performance liquid chromatography with fluorescence detection. Additionally, the CIMT of both the common and internal carotid arteries was measured. The levels of biopterins and CIMT were correlated using the Pearson correlation coefficient test.

Results
We did not find a significantly correlation between biopterins levels and CIMT. However, we found a significantly inverse correlation between the BH4/BH2 ratio and the CIMT in patients (r = -0.54, p < 0.01). A multiple regression analysis revealed that the CIMT correlated significantly and independently with the BH4/BH2 ratio.

Conclusion
Our results suggest that the BH4/BH2 ratio seems to be a better marker of vascular disease than biopterin levels.

Melioidosis is endemic in areas of Southeast Asia, however, there are no published reports from the Thai-Myanmar border. We report the first two cases of fatal melioidosis in this region. This is of great public health importance and highlights the need to increase clinical awareness of melioidosis on the Thai-Myanmar border and to assess the true burden of disease in the area through improved case detection and Burkholderia pseudomallei prevalence studies.

Published: January 2014

Treatment of an infected total elbow replacement (TER) is often successful in eradicating or suppressing the infection. However, the extensor mechanism may be compromised by both the infection and the surgery. The goal of this study was to assess triceps function in patients treated for deep infection complicating a TER. Between 1976 and 2007 a total of 217 TERs in 207 patients were treated for infection of a TER at our institution. Superficial infections and those that underwent resection arthroplasty were excluded, leaving 93 TERs. Triceps function was assessed by examination and a questionnaire. Outcome was measured using the Mayo Elbow Performance Score (MEPS).Triceps weakness was identified in 51 TERs (49 patients, 55%). At a mean follow-up of five years (0.8 to 34), the extensor mechanism was intact in 13 patients, with the remaining 38 having bone or soft-tissue loss. The mean MEPS was 70 points (5 to 100), with a mean functional score of 18 (0 to 25) of a possible 25 points.Infection following TER can often be eradicated; however, triceps weakness occurs in more than half of the patients and may represent a major functional problem.Cite this article: Bone Joint J 2014;96-B:82–7.
An extended posterior approach to the hip and pelvis for complex acetabular reconstruction that preserves the gluteal muscles and their neurovascular supply
Authors: Solomon L. B. , Hofstaetter J. G. , Bolt M. J. , Howie D. W. 
Published: January 2014

We investigated the detailed anatomy of the gluteus maximus, gluteus medius and gluteus minimus and their neurovascular supply in 22 hips in 11 embalmed adult Caucasian human cadavers. This led to the development of a surgical technique for an extended posterior approach to the hip and pelvis that exposes the supra-acetabular ilium and preserves the glutei during revision hip surgery. Proximal to distal mobilisation of the gluteus medius from the posterior gluteal line permits exposure and mobilisation of the superior gluteal neurovascular bundle between the sciatic notch and the entrance to the gluteus medius, enabling a wider exposure of the supra-acetabular ilium. This technique was subsequently used in nine patients undergoing revision total hip replacement involving the reconstruction of nine Paprosky 3B acetabular defects, five of which had pelvic discontinuity. Intra-operative electromyography showed that the innervation of the gluteal muscles was not affected by surgery. Clinical follow-up demonstrated good hip abduction function in all patients. These results were compared with those of a matched cohort treated through a Kocher–Langenbeck approach. Our modified approach maximises the exposure of the ilium above the sciatic notch while protecting the gluteal muscles and their neurovascular bundle. Cite this article: Bone Joint J 2014;96-B:48–53.
Debridementversusre-attachment of acetabular labral tears
Authors: Haddad B. , Konan S. , Haddad F. S. 
Published: January 2014

We have reviewed the current literature to compare the results of surgery aimed to repair or debride a damaged acetabular labrum. We identified 28 studies to be included in the review containing a total of 1631 hips in 1609 patients. Of these studies 12 reported a mean rate of good results of 82% (from 67% to 100%) for labral debridement. Of the 16 studies that reported a combination of debridement and re-attachment, five reported a comparative outcome for the two methods, four reported better results with re-attachment and one study did not find any significant difference in outcomes. Due to the heterogeneity of the studies it was not possible to perform a meta-analysis or draw accurate conclusions. Confounding factors in the studies include selection bias, use of historical controls and high rates of loss of follow-up.It seems logical to repair an unstable tear in a good quality labrum with good potential to heal in order potentially to preserve its physiological function. A degenerative labrum on the other hand may be the source of discomfort and its preservation may result in persistent pain and the added risk of failure of re-attachment. The results of the present study do not support routine refixation for all labral tears.Cite this article: Bone Joint J 2014;96-B:24–30.
Temporal trends and geographical variation in the use of subacromial decompression and rotator cuff repair of the shoulder in England

Published: January 2014

We explored the trends over time and the geographical variation in the use of subacromial decompression and rotator cuff repair in 152 local health areas (Primary Care Trusts) across England. The diagnostic and procedure codes of patients undergoing certain elective shoulder operations between 2000/2001 and 2009/2010 were extracted from the Hospital Episode Statistics database. They were grouped as 1) subacromial decompression only, 2) subacromial decompression with rotator cuff repair, and 3) rotator cuff repair only. The number of patients undergoing subacromial decompression alone rose by 746.4% from 2523 in 2000/2001 (5.2/100 000 (95% confidence interval (CI) 5.0 to 5.4) to 21 355 in 2009/2010 (40.2/100 000 (95% CI 39.7 to 40.8)). Operations for rotator cuff repair alone peaked in 2008/2009 (4.7/100 000 (95% CI 4.5 to 4.8)) and declined considerably in 2009/2010 (2.6/100 000 (95% CI 2.5 to 2.7)). Given the lack of evidence for the effectiveness of these operations and the significant increase in the number of procedures being performed in England and elsewhere, there is an urgent need for well-designed clinical trials to determine evidence of clinical effectiveness.

Quality assessment of guidelines on thromboprophylaxis in orthopaedic surgery
Authors: Sabharwal S. , Gauher S. , Kyriacou S. , Patel V. , Holloway I. , Athanasiou T. 
Published: January 2014

We evaluated the quality of guidelines on thromboprophylaxis in orthopaedic surgery by examining how they adhere to validated methodological standards in their development. A structured review was performed for guidelines that were published between January 2005 and April 2013 in medical journals or on the Internet. A pre-defined computerised search was used in MEDLINE, Scopus and Google to identify the guidelines. The AGREE II assessment tool was used to evaluate the quality of the guidelines in the study. Seven international and national guidelines were identified. The overall methodological quality of the individual guidelines was good. ‘Scope and Purpose’ (median score 98% interquartile range (IQR)) 86% to 98%) and ‘Clarity of Presentation’ (median score 90%, IQR 90% to 95%) were the two domains that received the highest scores. ‘Applicability’ (median score 68%, IQR 45% to 75%) and ‘Editorial Independence’ (median score 71%, IQR 68% to 75%) had the lowest scores. These findings reveal that although the overall methodological quality of guidelines on thromboprophylaxis in orthopaedic surgery is good, domains within their development, such as ‘Applicability’ and ‘Editorial Independence’, need to be improved. Application of the AGREE II instrument by the authors of guidelines may improve the quality of future guidelines and provide increased focus on aspects of methodology used in their development that are not robust.

A facile approach towards the synthesis of functionalized indenol derivatives identified as potent anti-oxidant and anti-bacterial agents
Authors: Taktouk Sonia , Ben Kraiem Jihene , Chaabane Hedia , Lebreton Jacques , Amri Hassen 
Published: January 2014

Â Â An elegant one-pot synthesis of new indenols 2 was successfully carried out, starting from 1-hydroxy-1H-indene-2-carboxylic acid 1. Thus, esterification of acid 1 with aliphatic alcohols in toluene at reflux and a catalytic amount of para-toluenesulfonic acid afforded the corresponding alkyl esters 2 in moderate to good yields. This classical esterification process enables an efficient entry to a variety of new indenol-based molecular models 2, which could be adapted to a range of drug candidates. All the synthesized compounds 2a-e were subjected to the preliminary evaluation for their potential anti-oxidant and anti-bacterial activities. The assessment of radical scavenging capacity of the compounds 2a-e towards the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) was measured and these compounds were found to scavenge DPPH free radical efficiently. Moreover, the in vitro antibacterial activity of derivatives 2a-e has been tested against a panel of pathogenic agents to show potent activity against all sensitive and resistant ones.
Bird–building collisions in the United States: Estimates of annual mortality and species vulnerability
Authors: Loss Scott R. , Will Tom , Loss Sara S. , Marra Peter P. 
Published: January 2014

Abstract
Building collisions, and particularly collisions with windows, are a major anthropogenic threat to birds, with rough estimates of between 100 million and 1 billion birds killed annually in the United States. However, no current U.S. estimates are based on systematic analysis of multiple data sources. We reviewed the published literature and acquired unpublished datasets to systematically quantify bird–building collision mortality and species-specific vulnerability. Based on 23 studies, we estimate that between 365 and 988 million birds (median = 599 million) are killed annually by building collisions in the U.S., with roughly 56% of mortality at low-rises, 44% at residences, and &lt;1% at high-rises. Based on &gt;92,000 fatality records, and after controlling for population abundance and range overlap with study sites, we identified several species that are disproportionately vulnerable to collisions at all building types. In addition, several species listed as national Birds of Conservation Concern due to their declining populations were identified to be highly vulnerable to building collisions, including Golden-winged Warbler (Vermivora chrysoptera), Painted Bunting (Passerina ciris), Canada Warbler (Cardellina canadensis), Wood Thrush (Hylocichla mustelina), Kentucky Warbler (Geothlypis formosa), and Worm-eating Warbler (Helmitheros vermivorum). The identification of these five migratory species with geographic ranges limited to eastern and central North America reflects seasonal and regional biases in the currently available building-collision data. Most sampling has occurred during migration and in the eastern U.S. Further research across seasons and in underrepresented regions is needed to reduce this bias. Nonetheless, we provide quantitative evidence to support the conclusion that building collisions are second only to feral and free-ranging pet cats, which are estimated to kill roughly four times as many birds each year, as the largest source of direct human-caused mortality for U.S. birds.

AbstractWe develop a version of Namba forcing which is useful for constructing models with no good scale on ℵω. A model is produced in whichholds for all finiten≥ 1, but there is no good scale on ℵω; this strengthens a theorem of Cummings, Foreman, and Magidor [3] on the non-compactness of square.
Rainbow Ramsey Theorem for Triples is Strictly Weaker than the Arithmetical Comprehension Axiom
Authors: Wang Wei 
Published: January 2014

AbstractWe prove that RCA0 + RRT ⊬ ACA0 where RRT is the Rainbow Ramsey Theorem for 2-bounded colorings of triples. This reverse mathematical result is based on a cone avoidance theorem, that every 2-bounded coloring of pairs admits a cone-avoiding infinite rainbow, regardless of the complexity of the given coloring. We also apply the proof of the cone avoidance theorem to the question whether RCA0 + RRT ⊦ ACA0 and obtain some partial answer.
Higher-Order Illative Combinatory Logic
Authors: Czajka Łukasz 
Published: January 2014

AbstractWe show a model construction for a system of higher-order illative combinatory logic thus establishing its strong consistency. We also use a variant of this construction to provide a complete embedding of first-order intuitionistic predicate logic with second-order propositional quantifiers into the system of Barendregt, Bunder and Dekkers, which gives a partial answer to a question posed by these authors.
Comparisons of Polychromatic and Monochromatic Ramsey Theory
Authors: Palumbo Justin 
Published: January 2014

AbstractWe compare the strength of polychromatic and monochromatic Ramsey theory in several set-theoretic domains. We show that the rainbow Ramsey theorem does not follow from ZF, nor does the rainbow Ramsey theorem imply Ramsey's theorem over ZF. Extending the classical result of Erdős and Rado we show that the axiom of choice precludes the natural infinite exponent partition relations for polychromatic Ramsey theory. We introduce rainbow Ramsey ultrafilters, a polychromatic analogue of the usual Ramsey ultrafilters. We investigate the relationship of rainbow Ramsey ultrafilters with various special classes of ultrafilters, showing for example that every rainbow Ramsey ultrafilter is nowhere dense but rainbow Ramsey ultrafilters need not be rapid. This entails comparison of the polychromatic and monochromatic Ramsey theorems as combinatorial principles on ω.

Published: January 2014

Scatter storage schemes are examined with respect to their applicability to dictionary lookup procedures. Of particular interest are virtual scatter methods which combine the advantages of rapid search speed and reasonable storage requirements. The theoretical aspects of computing hash addresses are developed, and several algorithms are evaluated. Finally, experiments with an actual text lookup process are described, and a possible library application is discussed.
Discours publicitaire et mythologie touristique
Authors: Kadri Boualem , Hamdani Kadri Djaouida 
Published: January 2014

Le voyage organisé ou le « tout inclus » joue un rôle paradoxal dans la dynamique unissant le tourisme et la société. En effet, malgré les critiques sévères évoquées à son endroit, cette forme de tourisme continue néanmoins de diffuser au travers d’un discours publicitaire une image idyllique du voyage, fondée sur la mythologie. Quelle lecture peut-on faire de cette mythologique touristique ? À partir d’un corpus constitué des brochures publicitaires du Club Med publiées dans les décennies 1990 et 2000, cet article a pour objectif de présenter une analyse des mythes en tourisme, dans le sillage de l’approche sémiologique de Roland Barthes et de l’approche anthropologique de Perrotetal.(1992). Il s’agit plus particulièrement de dévoiler comment l’organisation touristique construit un système second, à la fois parasite et mythique, à travers son discours et ses images qui relèvent « du langage de la culture dite de masse », afin d’établir une relation étroite entre le touriste-consommateur, la marque (Club Med) et la destination touristique.
Tourisme et lutte contre la pauvreté
Authors: Sarrasin Bruno , Tardif Jonathan , Arreola Flores Georgina 
Published: January 2014

Avec l’adoption en 2000 des objectifs du Millénaire pour le développement par les États membres de l’Organisation des Nations unies, la lutte contre la pauvreté est devenue indissociable du développement. Bien que la plupart des analyses s’attardent encore principalement à ses dimensions économiques, la pauvreté est maintenant comprise par les chercheurs, mais aussi par les institutions gouvernementales et non gouvernementales, comme une notion multidimensionnelle complexe qui interpelle toutes les disciplines. En raison notamment de sa croissance phénoménale dans les pays du Sud au cours de la dernière décennie, le tourisme est souvent envisagé par ces mêmes acteurs comme un vecteur de lutte contre la pauvreté, dont le tourisme « pro-pauvres » demeure l’exemple le mieux connu. À partir de la littérature scientifique publiée en anglais et en français depuis 1995, cet article propose un panorama de la recherche traitant des relations entre le tourisme et la pauvreté dans les pays du Sud. L’analyse de notre corpus confirme que cette relation est rarement abordée par les chercheurs et que ceux-ci contribuent très peu au renouvellement du débat sur le sujet, laissant non résolues les tensions entre la conceptualisation et l’opérationnalisation de ces notions.
Tourisme et « lutte contre la pauvreté » au Kirghizstan post-soviétique (Asie centrale)
Authors: Pabion Mouriès Johanne 
Published: January 2014

Le tourisme communautaire a été présenté au Kirghizstan (Asie centrale) comme un moyen de « lutte contre la pauvreté » par les multiples organisations internationales et ONG étrangères implantées dans le pays après l’indépendance. Cet article, basé sur plusieurs expériences de terrain et différentes méthodes d’analyse, met en face à face le « global » et le « local » en confrontant les discours et les objectifs officiels à ce que les acteurs impliqués en font sur le terrain. Il interroge la mise en place et l’appropriation locale d’un programme de développement touristique ayant pour but la réduction de la pauvreté. Il révèle comment l’idée de « lutte contre la pauvreté » est traduite et interprétée pour être, in fine, détournée de son objectif premier. Loin de servir les catégories les plus pauvres, le tourisme communautaire au Kirghizstan renforce le creusement des inégalités.
