Published: March 2012

BackgroundAdvancements in technology have created a current generation of guide catheters that not only provide stable access but also allow navigation of tortuous portions of the carotid siphon facilitating more distal access. Clinical experience since the release of the current generation of guide catheters was reviewed to determine their safety and efficacy.MethodsBetween October 2007 and November 2011, all neurointerventional procedures requiring access to the intracranial arterial circulation performed at our institution were reviewed. Clinical performance and complication rates of current generation guide catheters were compared with conventional guide catheters.Results1188 neurointerventional procedures were performed, of which 659 were eligible for this study. When navigating the anterior circulation, intracranial purchase was achieved significantly more often with current generation 0.070 inch and 0.053 inch guide catheters compared with conventional guide catheters. Similarly, current generation 0.070 inch and 0.053 inch catheters navigated at least one sharp 90° turn significantly more often than conventional guide catheters. Guide catheter related complications were encountered in 1.4% of cases with both catheter generations and differences were not significant although more complications were found when guide catheter tip position was cervical rather than intracranial.ConclusionCurrent generation guide catheters allow distal access with a high rate of success while maintaining a low rate of complications. When intracranial location of the guide catheter was obtained, fewer complications occurred.

ObjectiveChlamydia reinfection is common and increases the risk of reproductive complications. Guidelines for Australian general practitioners recommend retesting 3–12 months after a positive result but not before 6 weeks. The authors describe retesting rates among 16–29-year-old patients diagnosed as having chlamydia at 25 general practice clinics participating in the Australian Collaboration for Chlamydia Enhanced Sentinel Surveillance system.MethodsThe authors calculated annual testing and positivity rates for 16–29-year-olds attending in 2008–2009, re-attendance and retesting rates within <6 weeks, 1.5–4 months and 1.5–12 months of a positive test in 2008–2009 and positivity at retest (where results were available).ResultsThere were 50 408 individuals (60.4% women) who attended in 2008–2009. Annually, 7.4% and 7.3% were tested for chlamydia, of whom 9.1% and 8.0% tested positive, respectively. Within 1.5–4 months of a positive test, 24.6% re-attended and were retested (19% tested positive), 31.6% re-attended and were not retested and 43.9% did not re-attend. Within 1.5–12 months, 40% re-attended and were retested (16% tested positive), 40% re-attended and were not retested and 20% did not re-attend. Of individuals re-attending in 1.5–12 months but not retested, 50% had re-attended three or more times in the period. Within 6 weeks of a positive test, 25% were retested.DiscussionA high proportion of 16–29-year-olds re-attended general practices in the recommended retest periods, but retesting rates were low and multiple missed opportunities were common. The findings highlight the need for strategies such as electronic clinician prompts, patient recall systems and promotion of retesting guidelines.

BackgroundLittle is known about where sexually active female students access healthcare.ObjectivesUsing data from the Prevention of Pelvic Infection (POPI) cohort, the authors aimed to:Describe where sexually active female students aged ≤27 years reported accessing healthcare.Investigate the association between numbers of sexual partners during 12 months of follow-up and healthcare usage, health-related quality of life (EQ-5D) and demographic and behavioural characteristics.MethodsParticipants provided vaginal swabs and completed questionnaires on sexual health and quality of life at baseline and at a 12-month follow-up. The follow-up questionnaire also asked about healthcare attendances during the previous 12 months. Mann–Whitney tests were used to relate healthcare seeking behaviour and other characteristics to reported numbers of partners during follow-up.ResultsOf 1865 women included in the analysis, 79% paid at least one visit to their general practice during follow-up, 23% attended an accident and emergency/walk-in clinic, 21% a family planning clinic and 14% a genitourinary medicine clinic. As the number of sexual partners increased (0–1, 2–3, 4+), women were more likely to have visited a genitourinary medicine clinic (10%, 16%, 30%, p<0.001) or accident and emergency/walk-in clinic (21%, 26%, 29%, p<0.002). Women with more sexual partners were also more likely to smoke, use condoms, be aged <16 years at sexual debut, have bacterial vaginosis, chlamydia or gonorrhoea at baseline and to have lower EQ5-D scores.ConclusionThis is the first UK study of healthcare attendance in multiethnic female students recruited outside healthcare settings. The high attendance in general practice may represent a valuable opportunity for screening for sexually transmitted infections.
RESTRICTIONS ON THE GEOMETRY OF THE PERIODIC VORTICITY EQUATION

We prove that several evolution equations arising as mathematical models for fluid motion cannot be realized as metric Euler equations on the Lie group DIFF∞(𝕊1) of all smooth and orientation-preserving diffeomorphisms on the circle. These include the quasi-geostrophic model equation, cf. [A. Córdoba, D. Córdoba and M. A. Fontelos, Formation of singularities for a transport equation with nonlocal velocity, Ann. of Math. 162 (2005) 1377–1389], the axisymmetric Euler flow in ℝd(see [H. Okamoto and J. Zhu, Some similarity solutions of the Navier–Stokes equations and related topics, Taiwanese J. Math. 4 (2000) 65–103]), and De Gregorio's vorticity model equation as introduced in [S. De Gregorio, On a one-dimensional model for the three-dimensional vorticity equation, J. Stat. Phys. 59 (1990) 1251–1263].
EFFECT OF AMMONIA SOLUTION ON COMPOSITION, STRUCTURE AND MAGNETIC PROPERTIES OF CHEMICALLY PREPARED Co-B NANO-PARTICLES
Authors: SABAROU HOOMAN , ATAIE ABOLGHASEM 
Published: March 2012

In this study, the effect of ammonia solution addition as a pH adjusting component on the thermal behavior, phase composition, morphology, and magnetic properties of reduced Co - B nano-particles fabricated by chemical reduction route have been studied using DSC, XRD, SEM, and VSM techniques, respectively. Chemical composition of the samples was measured by ICP. The ICP results showed that basic pH of reagent solution, derived from utilizing ammonia solution, caused the boron content to decrease. XRD results indicated an amorphous structure for both samples synthesized with and without ammonia solution. Analysis of the DSC results showed that crystallization behavior has dramatically altered, owing to utilize ammonia solution. While the sample synthesized without ammonia solution showed three distinctive exothermic peaks at 216,470, and 540°C, the sample synthesized in the presence of ammonia solution exhibited only two exothermic peaks at 235 and 470°C and one endothermic peak at 370°C. SEM images reveal that the samples have a net- like morphology and the net is formed by many interconnected spherical fine particles with sizes less than 100 nm. Saturation magnetization of the sample synthesized in the presence of ammonia solution has improved significantly, probably due to the less amount of boron.

Published: March 2012

Barium hexaferrite ( BaFe 12 O 19) is a hard magnetic ceramic with superior magnetic properties and in powder form has potential for application in high density recording media. In this research a mechano-chemical approach was applied in order to achieve a nano-structured magnetic composite. Graphite was used to reduce barium hexaferrite in mechanical milling medium under argon atmosphere. Milling was carried out with a ball to powder mass ratio of 35 and rotation speed of 300 rpm. Effects of milling time on phase composition and morphology of the samples were evaluated by XRD and SEM techniques, respectively. XRD results revealed that after 20 hours of milling, nano-composite of BaFe 12 O 19/ Fe 3 O 4/ Fe 2 O 3 was obtained. By extending the milling time to 40 hours, FeO was detected as the dominant crystalline phase with crystallite size of 22 nm. Composite of Fe / FeO / Fe 3 O 4 was synthesized by controlled heat treatment of the 40 hours milled sample. SEM results revealed that particle size in the aforementioned heat treated composite sample reached to about 89 nm and the morphology of the samples changed slightly.

Published: March 2012

Higher environmental standards have made the removal of toxic metals such as hexavalent chromium from wastewater; an important problem for environmental protection. Iron oxide is a particularly interesting adsorbent to be considered for this application. In this study, a new method combining adsorption and magnetic separation was developed to remove Cr ( VI ) from wastewater. The nanocrystalline magnetite as adsorbent was produced via thermo- mechanical reduction of hematite. Various parameters which affect the adsorption of Cr ( VI ) such as time, pH, temperature and initial concentration were investigated using thermo-gravimeters (TG), X-Ray diffraction (XRD), scanning electron microscopy (SEM) and atomic adsorption spectroscopy (AAS) techniques. The maximum adsorption was occurred at pH 2. The adsorption data were fitted well to Langmuir isotherm model. The adsorption of Cr ( VI ) increased significantly with increasing of temperature and time.

Background—
Although individuals of Hispanic ethnicity are at high risk for developing heart failure (HF), little is known about differences between Hispanic HF patients stratified by left ventricular ejection fraction (EF). We compared characteristics, quality of care, and outcomes between Hispanic and non-Hispanic white patients hospitalized for HF with preserved EF (PEF) or reduced EF (REF).

Methods and Results—

From 247 hospitals in Get With The Guidelines–Heart Failure between 2005–2010, 6117 Hispanics were compared with 71 859 non-Hispanic whites. Forty-six percent of Hispanics had PEF (EF >40%), whereas 54% had REF (EF <40%); 55% and 45% of non-Hispanic whites had PEF and REF, respectively. Relative to non-Hispanic whites, Hispanics with PEF or REF were more likely to be younger and to have diabetes, hypertension, and overweight/obesity. In multivariate analysis, a lower mortality risk was observed among Hispanics with PEF (odds ratio, 0.50; 95% confidence interval, 0.31–0.81;
P
=0.005) but not in Hispanics with REF (odds ratio, 0.94; 95% confidence interval, 0.62–1.43;
P
=0.784) compared with non-Hispanic whites. In all groups, composite performance improved within the study period (Hispanics PEF: 75.2–95.1%; non-Hispanic whites PEF: 79.0–92.7%; Hispanics REF: 67.7–88.4%; non-Hispanic whites REF: 60.8–85.6%,
P
<0.0001).

Conclusions—
Hispanic HF patients with PEF had better in-hospital survival than non-Hispanic whites with PEF. Inpatient mortality was similar between groups with REF. Quality of care was similar and improved over time irrespective of ethnicity, highlighting the potential benefit of performance improvement programs in promoting equitable care.
Left Ventricular Systolic and Diastolic Function in Obstructive Sleep Apnea
Authors: Butt Mehmood , Dwivedi Girish , Shantsila Alena , Khair Omer A. , Lip Gregory Y.H. 
Published: March 2012

Background—
Previous studies in obstructive sleep apnea (OSA) were limited by study cohorts with comorbidities that confound assessment of left ventricular (LV) systolic and diastolic function. We comprehensively evaluated LV function using 2-dimensional echocardiography (2DE), tissue Doppler imaging (TDI), and 3-dimensional echocardiography (3DE) in subjects moderate-severe OSA, who were compared with disease (patients with hypertension, no OSA) and healthy control subjects.

Methods and Results—

A total of 120 subjects (n=40 each of matched OSA, hypertension and healthy cohorts) underwent echocardiographic examination for the assessment of septal and posterior wall thickness, LV mass index, LV volumes and ejection fraction, mitral valve inflow indices (E, A), mitral annular velocity (S, E′), and left atrial volume index (LAVI). OSA subjects were treated with continuous positive airway pressure (mean duration of 26 weeks), after which the echocardiographic parameters were reassessed. Posterior wall thickness and LV mass index were significantly higher in OSA and hypertensive groups compared with healthy. Systolic S velocity was reduced in OSA and hypertensive compared with healthy control subjects (
P
<0.05). Diastolic function (E/A, IVRT, and E/E′) was impaired in both OSA and hypertensive groups. On 3DE, mean LAVI was significantly greater in OSA and hypertensive compared with healthy. In OSA patients, continuous positive airway pressure therapy resulted in reduction of the posterior wall thickness (
P
=0.02) and improvement in LV ejection fraction (
P
<0.05), systolic S velocity (
P
<0.05), and diastolic LV impairment parameters.

Conclusions—
Moderate to severe OSA causes structural and functional changes in LV function and are comparable to that seen in hypertension. These abnormalities significantly improve after CPAP therapy.
Répertoire des subhāita des Indische Sprüche d'Otto Böhtlingk d'après le manuscrit no 4686 de la Bibliothèque nationale et universitaire de Strasbourg
Authors: Ducoeur Guillaume 
Published: March 2012

AbstractThe Bibliothèque nationale et universitaire de Strasbourg contains in its collection of Sanskrit manuscripts a small anonymous work dating from the 19th century with the title: “Böhtlingk Indische Sprüche. Ordre alphabétique des ouvrages d'où les maximes sont tirées.” The present study determines the precise date of this work and identifies its author as Georges-Louis Leblois (1825–1898), minister of the protestant Temple-Neuf de Strasbourg. It also establishes the original aim of the work. This repertory, being a historically unique tool for the use of Böhtlingk's Indische Sprüche, has been corrected and completed so that it may serve as an instrument for all those who will consult the three volumes of the great German scholar.
Meditating on the king's feet? Some remarks on the expression pādānudhyāta
Authors: Törzsök Judit , Ferrier Cédric 
Published: March 2012

AbstractThe Sanskrit expression -pādānudhyāta, often met with in inscriptions, is commonly translated as ‘meditating on the feet of.’ Adducing copious evidence from inscriptions as well as from classical Sanskrit literature, this article argues that the traditional translation is wrong, at least in the case of inscriptions dated before the tenth century AD. From the available sources it appears that meditation on the feet—whether on a god's or on a king's—came to be common practice only from around the tenth century in India. Moreover, several parallels show that the original understanding of the phrase was ‘favoured / blessed by the respected,’ pāda being an honorific term here. In addition to this argument, the study also attempts to define the nature of the hierarchical relationship that the above expression probably implied and to show that the wrong understanding of the term was probably due to misconceptions about the divine nature of kingship in ancient India.

Materialien zur geschichte des aaga-yoga I. Der aaga-yoga im Hinduismus
Authors: Grönbold Günter 
Published: March 2012

AbstractThe existence of a yoga-system with six limbs or parts instead of eight as in Patañjali's Yogasūtra has been known long since. Not known has been the multitude of texts with the six-limbed yoga in Hinduism. They can be arranged in three groups: (1) texts with a number of limbs other than six or eight, (2) texts which only mention the aaga-yoga but do not give details, (3) texts which treat the six-limbed yoga in full. Here we have two subgroups: (a) the Āsana-, (b) the Tarka-group (in this we can distinguish two divisions). The yoga of the last group is quite similar to the aaga-yoga of Buddhist Tantrism (regarding the order of limbs). In this article only questions can be formulated because the main problems cannot be answered at present. It is the first of a series giving materials for a history of the aaga-yoga.
One Cheer for Constantinople: A Comment on Pettit and Skinner on Hobbes and Freedom
Authors: Kukathas Chandran 
Published: March 2012

AbstractPhilip Pettit and Quentin Skinner find Hobbes's understanding of freedom as non-interference inadequate because it fails to appreciate what is wrong with a life lived as a slave. Though their critiques have some force, however, Hobbes's view of freedom has virtues of its own. It is highly sensitive to the fact that freedom is a matter of degree. It is also unlikely to mistake freedom for something else, like security or dignity. Moreover, Hobbes is not as unmindful of the dangers of servility as many think.
Attitudes towards Entrepreneurship in Singapore: The Role of the State in Cultural Transition
Authors: Pereira Alexius 
Published: March 2012

AbstractIn 2001, due to Singapore's low level of entrepreneurship, the state introduced an economic policy known as the Technopreneurship 21 programme. Along with many economic incentives and structural changes, the state has also embarked upon an ideological campaign to create a more pro-entrepreneurial society. This study focuses on examining the attitudes of undergraduates towards entrepreneurship as a means of understanding the Singapore state's ability to 'change' mindsets. It finds that although the respondents still feel that Singapore is currently still un-entrepreneurial, they are very positive for the future. Indeed, the undergraduates even felt that the best way for Singapore to become pro-entrepreneurial was for more state intervention. This paper concludes that because of the capacity and capability of the highly interventionist Singapore government, it is a key agent in the process of cultural transition in Singapore.
Dutch Colonial Anthropology in Indonesia
Authors: Kommers Jean , Buskens Léon 
Published: March 2012

AbstractAttempts to assess the results of colonial anthropology in Indonesia faced some problems, which, until recently, have not been dealt with properly. Therefore, in a newly published comprehensive history of anthropology in the Netherlands, several studies focused on the character, rather than on the substance of colonial anthropology. In the case of Dutch colonial representations of Indonesia, 'colonial anthropology' appears to be an assemblage of various disciplines that constituted a fragmented whole (Indologie; Dutch Indies Studies) from which today's Dutch academic anthropology emerged. However, projection of current conceptions of anthropology into the colonial past resulted in a tendency to neglect some major characteristics of early representations that are imperative for the interpretation of these representations. Besides, a rather limited familiarity amongst present-day anthropologists with the way in which Dutch colonial politics became immersed in international discourses resulted in misappraisal of an essential change in colonial knowledge: the shift from local to analytical representations, deeply affecting the portrayal of Indonesian cultures. In colonial knowledge production, emphasis moved from ethnographic particularism to essentialist conceptions like 'Knowledge of the Native'. This shift also had serious consequences for the academic position of ethnology amongst other colonial disciplines. Until recently, this misappraisal could escape notice because students of Dutch colonial anthropology were insufficiently aware of the effects on interpretation of the great variety of disciplinary discourses, so characteristic for Dutch colonial studies. Therefore, we will here concentrate on these effects and on the growing intertwinement of knowledge and politics which was directly related to the international orientation of colonial policy that became increasingly prominent after the mid-nineteenth century.

Family Ethics in 4QInstruction and the New Testament
Authors: Wold Benjamin 
Published: March 2012

Abstract4QInstruction preserves an interpretation of the fifth commandment, to honor one's father and mother, which has similarities with Philo's comments on it. Because Philo's treatment of the command plays a pivotal role in assigning influences on instruction to family members in the New Testament, and the present opinion overwhelmingly views Philo as indebted to Greek schemas and content, evidence from more recently available Qumran literature suggests some of the New Testament Haustafeln may have more of a Jewish intellectual history than is currently acknowledged. This article explores the way biblical traditions—especially the Decalogue and creation traditions—are used for construing teachings to members of the family in the 1 Cor 11, Eph 5-6, Philo and 4QInstruction.
