Sinus Floor Elevation and Implant Placement via the Crestal and Lateral Approach in Patients With Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome: Report of Two Cases
Authors: Stasko Sasha B. , Kolhatkar Shilpa , Bhola Monish 
Published: April 2013

Introduction: Implant placement in the posterior maxilla is frequently complicated by sinus proximity. Intraoral surgical procedures, including implant placement, have been described in patients with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS). Although reported widely in the general population, there is no description of implant placement with sinus floor augmentation (SFA) in these individuals. To the best of the authors’ knowledge, these are the first cases of SFA and implant placement via the crestal and lateral approaches in patients with HIV/AIDS.Case Presentation: A 50‐year‐old male presented for replacement of missing left maxillary first and second molars. Three‐dimensional radiography confirmed the presence of 3 to 5 mm of bone in the ideal implant positions. Lateral‐window SFA using a combination of particulate xenograft and allograft resulted in 10 mm of vertical height, allowing simultaneous placement of two implants. Restoration was completed after 6 months of healing. The second patient, a 40‐year‐old male, presented for replacement of a missing left maxillary first molar. Seven millimeters of native bone allowed a crestal approach for SFA. An oroantral communication was detected intraoperatively after several loads of bone graft had been added, and the decision was made to postpone implant placement. After 2.5 months, implant placement was completed, and the crown was delivered 6 months later. All implant‐retained restorations continue to function satisfactorily.Conclusions: Implant placement with SFA in well‐managed patients with HIV/AIDS is a viable treatment option. These case reports add to a growing body of evidence supporting the implementation of the full range of implant therapies in patients with HIV/AIDS.
Trends in Research using Plant Genetic Resources from Germplasm Collections: From 1996 to 2006

ABSTRACTThis paper examines how the use of genebank materials has changed from 1996 to 2006 using a similar survey by Dudnik et al. (2001) of reports published in 1996 as a baseline. Articles published in four journals generally used by genetic resource scientists were analyzed in each 2006 issue, as was done by Dudnik et al. in 2001. Studies involving genebank materials were selected and the following data were recorded: species used, locations of studies, affiliation of researchers, and sources of the materials and their uses. The analysis identified 320 studies in which a total of 57,935 accessions from 148 genebanks were used. Crop wild relatives were targeted in 20% of the studies. The study showed that a much higher percentage of accessions came from developed (87%) than from developing countries (7%) while 6% were supplied by CGIAR centers. The results in 2006 revealed an increase in the proportion of studies using genebank materials as compared to 1996. Genebank materials were used primarily for studies of genetic diversity, agromorphological and nutritional quality characteristics, biotic resistance, and mapping. Of the institutions carrying out the studies, 93% were from the public sector. However, there are still some barriers that limit the exchange of germplasm across borders. This implies that greater awareness among policymakers will be needed to facilitate the necessary exchange of plant genetic resources between countries to improve agricultural production.
Combining Ability for Total Phenols and Secondary Traits in a Diverse Set of Colored (Red, Blue, and Purple) Maize
Authors: Mahan A. L. , Murray S. C. , Rooney L. W. , Crosby K. M. 
Published: April 2013

ABSTRACTMaize (Zea mays L.) genetic diversity includes an array of kernel colors (red, blue, and purple), which are minimally used specialty corns when compared to yellow and white types commonly grown. Plant pigments are antioxidant phytochemicals produced as secondary metabolites. Antioxidants have been linked to various anticancer and other anti‐inflammatory health benefits. Alternate colors have been the subject of little breeding research, including the potential for high grain yield and high phenolic content from the same hybrid. We evaluated 84 maize hybrids from an 11‐parent diallel mating design, many of which were developed in Texas and lacked sufficient characterization. A high narrow‐sense heritability of 0.80 as well as very little genotype × environment (G×E) variation (4%) was observed for total phenolics. Because of low residual error, our trait analysis procedure proved robust in detecting and separating genotypes across diverse environments. Top combiners for phenolics were the purple ‘Maiz Morado’ with levels nearly twice as high as the red lines, the next highest. Maiz Morado's dark purple phenotype was visually dominant, masking all other colors, but complemented each parent's total phenolics. High per kernel antioxidants (as measured by total phenolics) and not top grain yield may be an option for producing the most total phenolics content. In the current study, the top colored hybrid yielded greater than twice the total phenolics as the top grain yellow hybrid.

Published: April 2013

IN BRIEF
Hypoglycemia is a serious adverse event leading to bad outcomes in hospitalized patients. The risk of hypoglycemia has been previously associated with the African-American race. This retrospective study of hospitalized older adults aimed to identify clinical factors that could explain this association. The home diabetes regimen partially explains the increased risk of hypoglycemia during hospitalization for older African-American men with diabetes.

AbstractA data set of amidino bis-benzimidazoles, in particular 2′-arylsubstituted-1H,1′H-[2,5′]bisbenzimidazolyl-5-carboximidine derivatives with anti-malarial activity against Plasmodium falciparum was employed in investigating the quantitative structure-activity relationship (QSAR). Quantum chemical and molecular descriptors were obtained from B3LYP/6-31g(d) calculations and Dragon software, respectively. Significant variables, which included total energy (E T), highest occupied molecular orbital (HOMO), Moran autocorrelation-lag3/weighted by atomic masses (MATS3m), Geary autocorrelation-lag8/weighted by atomic masses (GATS8m), and 3D-MoRSEsignal 11/weighted by atomic Sanderson electronegativities (Mor11e), were used in the construction of QSAR models using multiple linear regression (MLR) and artificial neural network (ANN). The results indicated that the predictive models for both the MLR and ANN approaches using leave-one-out cross-validation afforded a good performance in modelling the anti-malarial activity against P. falciparum as observed by correlation coefficients of leave-one-out cross-validation (R LOO-CV) of 0.9760 and 0.9821, respectively, root mean squared error of leave-one-out cross-validation (RMSELOO-CV) of 0.1301 and 0.1102, respectively, and predictivity of leave-one-out cross-validation (Q LOO-CV2) of 0.9526 and 0.9645, respectively. Model validation was performed using an external testing set and the results suggested that the model provided good predictivity for both MLR and ANN models with correlation coefficient of the external set (R Ext) values of 0.9978 and 0.9844, respectively, root mean squared error of the external set (RMSEExt) of 0.0764 and 0.1302 respectively, and predictivity of the external set (Q Ext2) of 0.9956 and 0.9690, respectively. Furthermore, the robustness of the QSAR models is corroborated by a number of statistical parameters, comprising adjusted correlation coefficient (R Adj2), standard deviation (s), predicted residual sum of squares (PRESS), standard error of prediction (SDEP), total sum of squares deviation (SSY), and quality factor (Q). The QSAR models so constructed provide pertinent insights for the future design of anti-malarial agents.

Published: April 2013

AbstractIn this paper, amphiphilic chitosan derivatives (N-octyl-N-mPEG-chitosan, mPEG = poly(ethylene glycol) monomethyl ether; OPEGC) were successfully synthesised via the Schiff base reduction reaction of chitosan and mPEG-aldehyde, or octanal, with chitosan acting as the backbone of the grafted copolymers, and mPEG-aldehyde providing the hydrophilic chain or octanal providing the hydrophobic alkyl chain. The synthesis was confirmed by characterisation employing Fourier transform infrared spectroscopy (FTIR) and 1H NMR. In the subsequent procedure, water-soluble quantum dots (QDs) and iron(II,III) oxide (IO) nanoparticles, widely used as nanoprobes in medical applications, were produced by the incorporation of QDs or IO inside the polymeric micelle core. Finally, the optical properties of QDs incorporated into OPEGC (OPEGC@QDs) were characterised by UV-VIS spectroscopy, fluorescence spectroscopy, cell viability was obtained through MTT, and the morphology of their assembly formed in water were observed by atomic force microscope (AFM) and transmission electron microscope (TEM) and the QDs content of OPEGC@QDs was calculated following thermo gravimetric analysis (TGA). In addition, the properties of IO incorporated into OPEGC (OPEGC@IO) were characterised by vibrating sample magnetometry (VSM), FT-IR, MTT, TGA, AFM, and TEM. The results indicated that the OPEGC composite nanoparticles with size narrowly distributed, good water solubility, and low cytotoxicity were prepared here, which represented a high quantum yield or good super-paramagnetism.
Violence and Resistance: Towards a Politics without a Scapegoat
Authors: Colborne Nathan 
Published: April 2013

Abstract: For René Girard, the cause of violence is deeper than the competition and conflict over scarce goods but emerges from the very structure of desire and the social mechanism that has developed to deal with it. The scapegoat mechanism both prevents the violence of the self's desire from destroying the entire community and conceals its own operation from the society that practises it. For this reason, attempts to eliminate or restrain violence that fail to come to terms with this mechanism and the genuine problem it addresses simply institutionalize scapegoating and extend its scope, perpetuating the very violence they seek to end. Girard exposes the workings of the scapegoat mechanism deep within the self in an attempt to overcome the violence that continues to haunt modern politics. I argue that Girard's thought can be complemented by the development of a politics, not in the sense of policy recommendations or institutional analysis, but an account of the practices by which an “interdividual” might overcome the scapegoat mechanism through and in the midst of practices that might stimulate actual political engagement. In this regard, William Cavanaugh's account of an alternative politics to what he calls the “performance” of the modern state is a useful conversation partner for Girard. Cavanaugh develops an account of concrete practices that have the potential to transform desire in ways Girard shows the need for, but never describes in concrete terms. Cavanaugh also embeds this in a particular social context that avoids the abstraction and individualism that a purely theoretical focus may result in.
Africa's Place in World Christianity: Towards a Theology of Intercultural Friendship
Authors: Ilo Stan Chu 
Published: April 2013

Abstract: This article argues that the polycentric map of World Christianity challenges theologians and scholars of religion in Africa to concentrate on how local processes are reinforcing local idioms in the appropriation of Christian faith in Africa. It proposes some steps in the missional and historical interpretation of African Christianity and the cultural currents that drive Christian expansion in Africa. The essay argues that analyzing and locating the place of African Christianity in World Christianity should begin with showing the eschatological fruits of God's kingdom in African history and how these relate to and are different from versions of Christianity outside the African context. The essay concludes with some proposals on the possible contributions of African Christianity to World Christianity in the development of a theology of cross-cultural friendship needed to meet the challenges of an uncertain world.

SummaryObjective: Pulmonary disorders are frequently characterized by the presence of adventitious sounds added to the breathing or base lung sound (BLS). The aim of this work was to assess the features of BLS in extrinsic allergic alveolitis (EAA) patients in comparison to healthy subjects, applying linear and nonlinear analysis techniques.Methods: We investigated the multichannel lung sounds on the posterior chest of 16 females, 8 healthy and 8 EAA patients, when breathing at 1.5 L/s. BLS linear features were obtained from the power spectral density (PSD) while nonlinear features were extracted by the concepts of irregularity and complexity, i.e., spectral, sample and multi-scale entropy.Results: The results demonstrated that spectral percentiles of BLS were lower in EAA patients than in healthy subjects but statistical significance (p<0.05) was obtained only for expiration at the left apical and both basal regions. Also, the maximum amplitude of the PSD in patients reached statistical significance ( p < 0.05) for the expiratory phase at basal regions. In the case of nonlinear techniques, significant lower values ( p < 0.05) were obtained for EAA patients during both respiratory phases at left apical and both basal regions.Conclusion: In conclusion, we found that BLS in chronic EAA patients is characterized by lower spectral percentiles, lower irregularity and lower complexity than in healthy subjects suggesting the feasibility of its clinical usefulness by screening its temporal alteration.

Objective.To assess whether hydroxychloroquine (HCQ) prevents early damage in patients with systemic lupus erythematosus (SLE).Methods.We updated an existing systematic review of literature on clinical effects of HCQ in patients with SLE. We conducted a nested case-control study embedded in an inception cohort of patients with SLE. Systemic Lupus International Collaborating Clinics Damage Index (SDI) at 3 years was considered as our primary outcome. Patients with SDI > 0 at 3 years were considered cases and patients with SDI = 0 were controls. Cases and controls were first compared by univariate analysis. Then conditional logistic regression models adjusting for potential confounders were done to study the effect of HCQ on damage accrual.Results.Included in the analysis were 481 patients who had 3 or more years of followup. Out of this cohort, we could match 151 cases with 151 controls. Univariate analysis identified age, the use of any immunosuppressive drugs, HCQ, and cumulative dose of steroids as significant covariates associated with damage accrual. In multivariate analysis, the use of HCQ remained significantly associated with less damage (OR 0.34, 95% CI 0.132–0.867), while age (OR 1.05, 95% CI 1.027–1.078) and a variable combining SLE activity and steroid dose (OR 1.73, 95% CI 1.306–2.295) were associated with damage at 3 years.Conclusion.We demonstrated that HCQ use was associated with less damage at 3 years after diagnosis of SLE when attention was given and adjustment done for disease activity and steroid dose, duration of disease, and calendar year of diagnosis.
Kynurenic Acid in Synovial Fluid and Serum of Patients with Rheumatoid Arthritis, Spondyloarthropathy, and Osteoarthritis
Authors: Parada-Turska Jolanta , Zgrajka Wojciech , Majdan Maria 
Published: April 2013

Objective.Previously we demonstrated that kynurenic acid (KYNA), an endogenous metabolite of kynurenine, is present in the synovial fluid of patients with rheumatoid arthritis (RA). KYNA inhibits proliferation of synoviocytesin vitro. The goal of our study was to compare KYNA concentrations in synovial fluid and blood of patients with RA, inflammatory spondyloarthropathies (SpA), and osteoarthritis (OA).Methods.Serum and synovial fluid samples were obtained from 189 patients with RA, 56 patients with SpA, and 32 patients with OA. KYNA was separated using a high-performance liquid chromatography system and measured fluorometrically.Results.KYNA concentration in synovial fluid obtained from patients with RA and SpA was significantly lower than that in patients with OA (p < 0.05). The concentration of KYNA in serum of patients with RA, SpA, and OA did not differ among all groups studied. The positive correlation between KYNA content in synovial fluid and serum was found in patients with RA (p < 0.05). Univariate linear regression analysis demonstrated that fibrinogen was significantly associated with KYNA in synovial fluid (p < 0.05), and red blood cell counts, morning stiffness, and pain scores were significantly associated with KYNA level in serum (all p < 0.05). Multivariate regression analysis revealed correlation between the following independent variables: hemoglobin level, hematocrit, red blood cell count in conjunction with age and KYNA content in synovial fluid. A lack of correlation was observed between KYNA content in synovial fluid of patients with RA and other clinical and laboratory measures of disease activity.Conclusion.Our data show a local deficit of KYNA in inflammatory states.
Les paradigmes du « Néolibéralisme »
Authors: Audier Serge 
Published: April 2013

Pour certains, le néolibéralisme évoque la dérégulation et le retrait de l’État, alors que, pour d’autres, il serait un constructivisme concurrentiel fondé sur une anthropologie de l’individu-entreprise. Cette seconde interprétation, qui se réclame de Michel Foucault, est aujourd’hui très diffusée. Une autre approche est toutefois ici proposée, qui prend au sérieux les controverses entre protagonistes du néolibéralisme. Celles-ci révèlent des désaccords de fond, notamment au plan méthodologique. Sous cet angle seront examinées des divergences entre l’école autrichienne, l’école de Chicago et l’école libérale allemande : par-delà certaines ressemblances, leur vision du marché, du rôle de l’État, du cadre juridique, moral ou sociologique diffère sensiblement.

Vers une nouvelle économie des services publics durables
Authors: Gauthier Caroline , Meyronin Benoît 
Published: April 2013

Cette contribution vise à analyser, à travers quatre études de cas, la dimension « développement durable » d’innovations de service prenant appui sur des formes originales de partenariat public-privé. Ces innovations présentent la caractéristique de rechercher certaines formes d’équilibres entre territoires, entre populations ou encore entre modes de déplacement. Il semble donc légitime de questionner leur contenu « durable » pour avancer quelques hypothèses concernant les rapports qu’entretiennent l’économie des services et le développement durable. Nous avançons alors l’hypothèse selon laquelle ce contexte partenarial serait particulièrement propice au développement d’innovations tertiaires durables, que l’implication des parties prenantes est un facteur clé de succès de l’innovation de service – et invitons ainsi les décideurs à s’inscrire dans ce type de partenariats pour développer ces nouveaux services durables.
