A series of complexes of Cu(II), Ni(II), Co(II), Mn(II) and Cd(II) with Isonicotinoylhydrazone‐4‐diphenylaminobenzaldehyde (INHDAB) has been reported. The complexes have been characterized by analytical data, IR, UV‐Vis, NMR spectra, magnetic susceptibility values, thermal analysis and for the Cu(II) complex the ESR spectrum has been registered. The biological activity of these complexes were investigated against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella enteritidis and Shigella flexneri bacteria. The INHDAB ligand is coordinate at the metallic ions by oxygen amide (O=C) and the azomethine nitrogen.Erratum to “Transition Metal Complexes of Isonicotinoyl–hydrazone-4-diphenylaminobenzaldehyde: Synthesis, Characterization and Antimicrobial Studies”dx.doi.org/10.1155/2012/759758
Timing Perception in Paintings and Sculptures of Edgar Degas
Authors: Nather Francisco Carlos , Bueno José Lino Oliveira 
Published: March 2012

AbstractThe impressionist artist Edgar Degas (1834-1917) is widely known for his artistic production dedicated to the representation of movement. Degas has done a careful study, realistically depicting the movement both in his paintings of scenes of horses, women bathing and dancing, and in his sculptures of dancers in various positions of classical ballet. Since movements exist only at the intersection space-time, and visual works of art exist only in physical spaces defined by the works themselves, this article discusses the perception of time in the work of Degas. Therefore, this paper emphasizes aspects of the representation of movement used by the artist and the implied relations of these aspects with the perception of time. The timing perception is addressed according to studies that revealed components of the subjective perception of time related to a meeting of an observer with a work of visual art (aesthetic episode).
Religious Transnationalism: The case of Zimbabwean Catholics in Britain
Authors: Pasura Dominic 
Published: March 2012

AbstractThis article examines the ways in which mainstream churches engender migrants’ maintenance of transnational ties and improve their integration into British society. It uses the Zimbabwean Catholic congregation in Birmingham as a case study. The central thrust of this article is that African diaspora congregations have emerged as public spaces to construct transnational identities and provide alternative forms of belonging, and have reinvented themselves as agents of re-evangelization to the host society. In contrast to other transnational ties such as remittances and hometown associations whose activities are orientated toward the homeland, reverse evangelization embodies the giving out of something to the host society. It is the awareness and ability to influence and shape the face of Christianity in Britain that gives African Christian migrants the agency to participate in other aspects of British society, providing an alternative path to integration. As the article argues, religious identities among Zimbabwean migrants should be seen not just as a religious phenomenon but also as markers of cultural difference from the host society, which constructs them as ‘other’.
‘Truly We Have a Good Heritage’: Musical Mediations in a Yoruba Christian Diaspora
Authors: Brennan Vicki L. 
Published: March 2012

AbstractThis essay discusses the Asaphs of Seraph, a Yoruba Christian organization based in the United States whose primary activity consists of holding an annual convention for current and former members of Cherubim and Seraphim churches in Nigeria. I examine how the Asaphs of Seraph use musical performances and media to circulate Yoruba Christian forms of practice and subjectivity. Through an analytic focus on processes of mediation and circulation, I explore how the Asaphs of Seraph produce and maintain diasporic consciousness and community through the use of religious music.
The Changing Nature of Literary Censorship, 1961-1965
Authors: Loewenstein Karl E. 
Published: March 2012

From 1961-1965, the Writers’ Union was transformed from a place where writers debated and primarily made their own decisions about what to publish to an organization under watchful gaze of official censors at Glavlit (the Main Administration for the Protection of Military and State Secrets in the Press). In these years, decision-making authority switched from give and take within the union to censors who had ideological, not literary expertise.
Although Glavlit played a secondary role in late Stalinist and early Khrushchev censorship, its power and relevance grew before Khrushchev’s fall. Glavlit began to censor ideological content and remove the decision-making process from the hands of editors. Censorship began to take on the same characteristics as ideological work throughout society in that it became increasingly disconnected from real questions of the moment. The censors strove to reproduce approved ideological formulations with much less attention to actual content. Glavlit’s new approach to censorship and increasing power drove innovative writers away from the official channels of publication. Thus, the internal struggles of the Moscow Writers’ Union and their confrontation with literary censors during the early years of the 1960s were crucial for ushering in a more repressive age.

“Think Tanks” and Public Policy Centers in Russia and Other Post-Communist Countries: Development and Function
The main objective of this paper is the analysis of the development of Think Tanks and Public Policy Centers in Russia and other post-communist countries. Think Tanks are small practically oriented research teams comprising both academic researchers and experts who are familiar with political practices and capable of implementing proposed solutions to topical problems in social and political life. In the community of Think Tanks, which usually carry out commissions we can distinguish one type, the activities of which are based on a socially significant idea, i.e. the promotion of development in post-authoritarian and post-communist states by encouraging truly public and open policy. In early 21st century such organizations were named “Public Policy Centers” (PPC).

Implementation of the Daytime Cloud Optical and Microphysical Properties Algorithm (DCOMP) in PATMOS-x
Authors: Walther Andi , Heidinger Andrew K. 
Published: March 2012

AbstractThis paper describes the daytime cloud optical and microphysical properties (DCOMP) retrieval for the Pathfinder Atmosphere’s Extended (PATMOS-x) climate dataset. Within PATMOS-x, DCOMP is applied to observations from the Advanced Very High Resolution Radiometer and employs the standard bispectral approach to estimate cloud optical depth and particle size. The retrievals are performed within the optimal estimation framework. Atmospheric-correction and forward-model parameters, such as surface albedo and gaseous absorber amounts, are obtained from numerical weather prediction reanalysis data and other climate datasets. DCOMP is set up to run on sensors with similar channel settings and has been successfully exercised on most current meteorological imagers. This quality makes DCOMP particularly valuable for climate research. Comparisons with the Moderate Resolution Imaging Spectroradiometer (MODIS) collection-5 dataset are used to estimate the performance of DCOMP.
Data Clustering Reveals Climate Impacts on Local Wind Phenomena
Authors: Clifton Andrew , Lundquist Julie K. 
Published: March 2012

AbstractThe authors demonstrate the utility of k-means clustering for identifying relationships between winds at turbine heights and climate oscillations, thereby developing a method suited for predicting the impacts of climate change on wind resources. Fourteen years of data from an 80-m tower at the National Wind Technology Center (NWTC) in Colorado have been reduced to four dominant flow phenomena using k-means clustering. At this location, this method identifies two clusters of westerly inflow (strong and weak), another cluster of flow from the north, and one of flow from the south. Similar clusters are found for the data at all heights on the tower, and each follow distinct seasonal cycles. Time series of each cluster, as well as the mean wind speed at the NWTC, are retained for comparison with climate oscillations along with the local 500-hPa pressure gradient. The mean wind speed in the surface layer is strongly correlated with the local north–south pressure gradient. The frequency of strong westerly flow is also negatively correlated with the Niño-3.4 index, whereas weaker westerly winds are negatively correlated with the Pacific–North American pattern (PNA) and Arctic Oscillation (AO). Northerly winds at the NWTC did not strongly correlate with any of the investigated climate indices (AO, PNA, and Niño-3.4). These northerly winds occur more frequently in the summer months, suggesting that these winds are more influenced by local conditions than by mesoscale forcing. This method of identifying clusters in wind data allows objective identification of wind phenomena that may benefit the deployment of wind turbines, for example, in choosing combinations of wind speed and direction to investigate for turbine siting.
Observation-Consistent Input and Whitecapping Dissipation in a Model for Wind-Generated Surface Waves: Description and Simple Calculations
Authors: Rogers W. Erick , Babanin Alexander V. , Wang David W. 
Published: March 2012

Abstract
A new wind-input and wind-breaking dissipation for phase-averaged spectral models of wind-generated surface waves is presented. Both are based on recent field observations in Lake George, New South Wales, Australia, at moderate-to-strong wind-wave conditions. The respective parameterizations are built on quantitative measurements and incorporate new observed physical features, which until very recently were missing in source terms employed in operational models. Two novel features of the wind-input source function are those that account for the effects of full airflow separation (and therefore relative reduction of the input at strong wind forcing) and for nonlinear behavior of this term. The breaking term also incorporates two new features evident from observational studies; the dissipation consists of two parts—a strictly local dissipation term and a cumulative term—and there is a threshold for wave breaking, below which no breaking occurs. Four variants of the dissipation term are selected for evaluation, with minimal calibration to each. These four models are evaluated using simple calculations herein. Results are generally favorable. Evaluation for more complex situations will be addressed in a forthcoming paper.
An Overview of the Global Historical Climatology Network-Daily Database
Authors: Menne Matthew J. , Durre Imke , Vose Russell S. , Gleason Byron E. , Houston Tamara G. 
Published: March 2012

Abstract
A database is described that has been designed to fulfill the need for daily climate data over global land areas. The dataset, known as Global Historical Climatology Network (GHCN)-Daily, was developed for a wide variety of potential applications, including climate analysis and monitoring studies that require data at a daily time resolution (e.g., assessments of the frequency of heavy rainfall, heat wave duration, etc.). The dataset contains records from over 80 000 stations in 180 countries and territories, and its processing system produces the official archive for U.S. daily data. Variables commonly include maximum and minimum temperature, total daily precipitation, snowfall, and snow depth; however, about two-thirds of the stations report precipitation only. Quality assurance checks are routinely applied to the full dataset, but the data are not homogenized to account for artifacts associated with the various eras in reporting practice at any particular station (i.e., for changes in systematic bias).
Daily updates are provided for many of the station records in GHCN-Daily. The dataset is also regularly reconstructed, usually once per week, from its 20+ data source components, ensuring that the dataset is broadly synchronized with its growing list of constituent sources. The daily updates and weekly reprocessed versions of GHCN-Daily are assigned a unique version number, and the most recent dataset version is provided on the GHCN-Daily website for free public access. Each version of the dataset is also archived at the NOAA/National Climatic Data Center in perpetuity for future retrieval.
Priority setting of ICU resources in an influenza pandemic: a qualitative study of the Canadian public's perspectives

Published: March 2012

Abstract

Background
Pandemic influenza may exacerbate existing scarcity of life-saving medical resources. As a result, decision-makers may be faced with making tough choices about who will receive care and who will have to wait or go without. Although previous studies have explored ethical issues in priority setting from the perspective of clinicians and policymakers, there has been little investigation into how the public views priority setting during a pandemic influenza, in particular related to intensive care resources.

Methods
To bridge this gap, we conducted three public town hall meetings across Canada to explore Canadian's perspectives on this ethical challenge. Town hall discussions group discussions were digitally recorded, transcribed, and analyzed using thematic analysis.

Results
Six interrelated themes emerged from the town hall discussions related to: ethical and empirical starting points for deliberation; criteria for setting priorities; pre-crisis planning; in-crisis decision-making; the need for public deliberation and input; and participants' deliberative struggle with the ethical issues.

Conclusions
Our findings underscore the importance of public consultation in pandemic planning for sustaining public trust in a public health emergency. Participants appreciated the empirical and ethical uncertainty of decision-making in an influenza pandemic and demonstrated nuanced ethical reasoning about priority setting of intensive care resources in an influenza pandemic. Policymakers may benefit from a better understanding the public's empirical and ethical 'starting points' in developing effective pandemic plans.
Understanding determinants of socioeconomic inequality in mental health in Iran's capital, Tehran: a concentration index decomposition approach

Published: March 2012

AbstractBackgroundMental health is of special importance regarding socioeconomic inequalities in health. On the one hand, mental health status mediates the relationship between economic inequality and health; on the other hand, mental health as an "end state" is affected by social factors and socioeconomic inequality. In spite of this, in examining socioeconomic inequalities in health, mental health has attracted less attention than physical health. As a first attempt in Iran, the objectives of this paper were to measure socioeconomic inequality in mental health, and then to untangle and quantify the contributions of potential determinants of mental health to the measured socioeconomic inequality.MethodsIn a cross-sectional observational study, mental health data were taken from an Urban Health Equity Assessment and Response Tool (Urban HEART) survey, conducted on 22 300 Tehran households in 2007 and covering people aged 15 and above. Principal component analysis was used to measure the economic status of households. As a measure of socioeconomic inequality, a concentration index of mental health was applied and decomposed into its determinants.ResultsThe overall concentration index of mental health in Tehran was -0.0673 (95% CI = -0.070 - -0.057). Decomposition of the concentration index revealed that economic status made the largest contribution (44.7%) to socioeconomic inequality in mental health. Educational status (13.4%), age group (13.1%), district of residence (12.5%) and employment status (6.5%) also proved further important contributors to the inequality.ConclusionsSocioeconomic inequalities exist in mental health status in Iran's capital, Tehran. Since the root of this avoidable inequality is in sectors outside the health system, a holistic mental health policy approach which includes social and economic determinants should be adopted to redress the inequitable distribution of mental health.
Genetic variants of p27 and p21 as predictors for risk of second primary malignancy in patients with index squamous cell carcinoma of head and neck

Published: March 2012

Abstract

Background
Cell cycle deregulation is common in human cancer, and alterations of p27 and p21, two critical cell cycle regulators, have been implicated in the development of many human malignancies. Therefore, we hypothesize that p27 T109G polymorphism individually or in combination with p21 (C98A and C70T) polymorphisms modifies risk of second primary malignancy (SPM) in patients with index squamous cell carcinoma of head and neck (SCCHN).

Methods
A cohort of 1,292 patients with index SCCHN was recruited between May 1995 and January 2007 at the M.D. Anderson Cancer Center and followed for SPM occurrence. Patients were genotyped for the three polymorphisms. A log-rank test and Cox proportional hazards models were used to compare SPM-free survival and SPM risk.

Results
We found that patients with p27 109 TG/GG, p21 98 CA/AA and p21 70 CT/TT variant genotypes had a worse SPM-free survival and an increased SPM risk than those with the corresponding p27 109 TT, p21 98 CC, and p21 70 CC common genotypes, respectively. After combining the three polymorphisms, there was a trend for significantly increased SPM risk with increasing number of the variant genotypes (P
trend = 0.0002). Moreover, patients with the variant genotypes had an approximately 2.4-fold significantly increased risk for SPM compared with those with no variant genotypes (HR, 2.4, 95% CI, 1.6-3.6).

Conclusions
These results suggest that p27 T109G polymorphism individually or in combination with p21 (C98A and C70T) polymorphisms increases risk of SPM in patients with index SCCHN.

Abstract

Background
Transcatheter aortic valve implantation (TAVI) is a promising therapy for patients with severe aortic stenosis (AS) and high perioperative risk. New echocardiographic methods, including 2D Strain analysis, allow the more accurate measurement of left ventricular (LV) systolic function. The goal of this study was to describe the course of LV reverse remodelling immediately after TAVI in a broad spectrum of patients with symptomatic severe aortic valve stenosis.

Methods
Thirty consecutive patients with symptomatic aortic valve stenosis and preserved LVEF underwent transfemoral aortic valve implantation. We performed echocardiography at baseline and one week after TAVI. Echocardiography included standard 2D and Doppler analysis of global systolic and diastolic function as well as 2D Strain measurements of longitudinal, radial and circumferential LV motion and Tissue Doppler echocardiography.

Results
The baseline biplane LVEF was 57 ± 8.2%, the mean pressure gradient was 46.8 ± 17.2 mmHg and the mean valve area was 0.73 ± 0.27 cm2. The average global longitudinal 2D strain of the left ventricle improved significantly from -15.1 (± 3.0) to -17.5 (± 2.4) % (p < .001). This was reflected mainly in improvement in the basal and medial segments while strain in the apex did not change significantly [-11.6 (± 5.2) % to -15.1 (± 5.5) % (p < .001), -13.9 (± 5.1) % to -16.8 (± 5.6) % (p < .001) and -19.2 (± 7.0) % to -20.0 (± 7.2) % (p = .481) respectively]. While circumferential strain [-18.1 (± 5.1) % vs. -18.9 (± 4.2) %, p = .607], radial strain [36.5 (± 13.7) % vs. 39.7 (± 17.2) %, p = .458] and the LVEF remained unchanged after one week [57.0 (± 8.2) % vs. 59.1 (± 8.1) %, p = .116].

Conclusion
There is an acute improvement of myocardial longitudinal systolic function of the basal and medial segments measured by 2D Strain analysis immediately after TAVI. The radial, circumferential strain and LVEF does not change significantly in all patients acutely after TAVI. These data suggest that sensitive new echo methods can reliably detect early regional changes of myocardial function after TAVI before benefits in LVEF are detectable.
Stimulation of TLR4 by recombinant HSP70 requires structural integrity of the HSP70 protein itself
Authors: Luong Michael , Zhang Yanyu , Chamberlain Tim , Zhou Tianhui , Wright Jill F , Dower Ken , Hall J Perry 
Published: March 2012

Abstract

Background
Toll-like receptor 4 (TLR4) is activated by bacterial endotoxin, a pathogen-associated molecular pattern (PAMP). It has been suggested that TLR4 can also be activated by damage-associated molecular pattern (DAMP) proteins such as HSP70. It remains a challenge to provide unequivocal evidence that DAMP proteins themselves play a role in TLR4 activation, as the DAMP proteins used are often contaminated with endotoxin and other TLR ligands introduced during protein expression and/or purification.

Results
Here we report that the activation of TLR4 on primary human macrophage cultures by recombinant HSP70 is not solely due to contaminating endotoxin. Polymyxin B pretreatment of HSP70 preparations to neutralize contaminating endotoxin caused significant reductions in the amount of TNF-α induced by the recombinant protein. However, digestion of HSP70 with Proteinase K-agarose beads also dramatically reduced the TNF-α response of macrophages to HSP70, while leaving levels of contaminating endotoxin largely unchanged relative to controls.

Conclusions
These results indicate that the stimulatory effect of recombinant HSP70 requires both the presence of endotoxin and structural integrity of the heat shock protein itself.
