Authors: Jamayet Nafij Bin , Eusuf Zai Sumaiya Zabin , Hossain Sharafat , Alif  Retracted Sheikh Mohammad 
Published: February 2013

Background: After a total glossectomy, one lost the ability to speak and swallow due to the loss of tongue mobility and the increase of space between the palate and tongue remnants. To improve swallowing by creating negative pressure, tongue and palatal drop prostheses can be utilized. This prosthesis does not restore other tongue functions such as mastication, speech articulation and resonance because the prosthesis cannot reproduce natural tongue movements. Purpose: To rehabilitate the tongue deformity due to the gun shot wound. Methods and Materials: The case report revealed the total lost of tongue of a Bangladeshi patient who cannot be able to swallow and speak. The remaining teeth still fully intact but the palatal drop and tongue prosthesis was fabricated with the silicone prosthesis. Results: Both palatal drop prosthesis and tongue prosthesis allowed the patient to increase the capacity to swallow and reduce the remaining odondus space. The speech appeared to be more intelligiable but cannot fully restore. Conclusion: The quality of life of a patient after post operative follow-up appeared to be better; however, the physiologic function of the missing organ cannot fully restored.DOI: http://dx.doi.org/10.3329/cdcj.v10i1.13828City Dent.

Published: February 2013

Background: The purpose of this study was to develop a new class of influenza A virus haemagglutinin (HA) blockers by tethering thiosialoside molecules to metal nanoparticles and producing glycoclusters that enhance the affinity of HA binding by N-acetylneuraminic acid. Methods: Oxygen of the glycoside bond of sialoside was replaced with sulfur to prevent hydrolytic digestion of the N-acetylneuraminic acid residue by viral neuraminidase. Two novel thiosialosides, α-2- S-[ p-( N-levulinyl) aminophenyl]-5- N-acetylneuraminic acid (Neu5Ac- S-Lev) and α-2- S-[ m-( N-levulinyl)aminobenzyl]-5- N-acetylneuraminic acid (Neu5Ac- S-CH2-Lev), were tethered onto the surface of metal nanoparticles via an aminooxy functionalized thiol linker in a glycoblotting reaction. Gold (Au) and silver (Ag) nanoparticles were coated simultaneously with 11-mercaptoundecyl phosphorylcholine to reduce non-specific adsorption of proteins. Phosphorylcholine self-assembled monolayercoated metals displaying clustered Neu5Ac (Neu5Ac-PCSAM-Au and Neu5Ac-PCSAM-Ag) were subjected to haemagglutination inhibition (HI) assays using the influenza A virus strain A/PR/8/1934 (H1N1). Results: Glyconanoparticles with thiosialosides had potent HI activities. In particular, Neu5Ac-PCSAM-Au with a diameter of 20 nm corresponding to 9.8 μM monosaccharide Neu5Ac was the most potent HA inhibitor. The versatility of this strategy was demonstrated by similar submicromolar HI activities of Neu5Ac-PCSAM-Ag with diameters of 50 nm and 150 nm. Conclusions: Glycosylated metal nanoparticles were designed and synthesized as potent influenza A virus HA blockers. This study may contribute to the acceleration of the discovery of a new class of nanoparticle anti-influenza drugs.
Groupes d'appartenance et vie institutionnelle des psychanalystes. Plaidoyer pour une plus grande ouverture des commissions d'enseignement
Authors: Heenen-Wolff Susann 
Published: February 2013

Résumé L’auteur soutient l’hypothèse que le fonctionnement de la plupart des sociétés psychanalytiques, notamment des commissions qui gèrent l’enseignement, est teinté de l’héritage du « comité secret », fondé par Freud dans le but de préserver le noyau de la psychanalyse. Sur l’arrière-fond de la diversité de la psychanalyse contemporaine, l’opérationnalité de ce fonctionnement est mise en question. Les définitions de ce que sont la « véritable » psychanalyse et un « bon analyste » sont devenues plus floues que jamais, ce qui a des répercussions importantes sur les processus d’évaluation au sein des institutions : nous devons évaluer des postulants, des candidats, des membres aspirants, des analystes formateurs, sans disposer de critères clairs et partagés. Ce manque de critères contribue à une perception des institutions analytiques comme si elles fonctionnaient à l’instar d’une secte. L’auteur se demande si une plus grande transparence des modalités de l’évaluation lors de la sélection des candidats ou de leur habilitation ne pourrait pas contribuer à une attractivité accrue de la formation telle qu’elle est organisée par les sociétés psychanalytiques, qu’elles soient composantes de l’Association psychanalytique internationale ( IPA ) ou pas.
Savoir et système de genre au Chili : une connaissance à vocation politique et pragmatique dans un contexte de démocratisation
Authors: Marques-Pereira Bérengère 
Published: February 2013

Résumé Depuis le passage à la démocratie, le Chili a vu se développer une politisation du genre, tant au niveau des agences étatiques consacrées aux droits des femmes qu’au niveau des groupes féministes. La notion de genre, fruit de savoirs à la fois militants et académiques, y a connu un glissement de sens notable (le genre comme catégorie, comme identité, comme concept normatif, comme outil pragmatique) à travers les trois modalités majeures de l’exercice de la responsabilité publique par les féministes dites institutionnelles : réflexion sur les formes prises par l’exclusion des femmes de l’espace public, participation à l’élaboration de la normativité sociale et, enfin, vigilance à l’égard des institutions et des appareils de l’État. Les propositions politiques sur les droits des femmes, élaborées dès la dictature par les groupes féministes, ont conduit, depuis le retour à la démocratie, à des discours publics pouvant relever d’une naturalisation, d’une politisation ou d’une sociologisation des rapports de genre.
Approches multiniveaux du dilemme de la question nucléaire en Corée du Nord et de la sécurité en Asie du Nord-Est
Authors: Chun Kwang-Ho 
Published: February 2013

Résumé La plupart des analystes qui étudient la Corée du Nord ont adopté ce que Kenneth Waltz appelle une « approche réductionniste » qui permet certainement de comprendre certains des comportements de la Corée du Nord sur la scène internationale mais qui échoue à en donner un aperçu global. Afin de combler cette lacune, cet article adopte une approche de la politique étrangère de la Corée du Nord de l’après-Guerre froide à plusieurs niveaux tels que la « théorie des jeux à deux niveaux » de Robert Putnam et la « perspective stratégique » de Bruce Bueno de Mesquita. Une telle approche permet de mieux expliquer le raisonnement sous-jacent et les modèles fondamentaux qui orientent le comportement répétitif de ce pays dans l’après-Guerre froide.
Éthique, finances et anthropologie
Authors: Gagey Henri-Jérôme 
Published: February 2013

Résumé Cet article constitue une réaction à l’argument développé dans ce dossier par Christian Walter. Il récuse un moralisme prompt à dénoncer les excès de la spéculation au nom d’une référence mythique aux régularités de l’économie « réelle » sans prendre le chemin long d’une analyse des choix éthiques impliqués dans les outils mathématiques d’analyse des marchés. Ce refus d’opposer la mauvaise spéculation artificielle aux régularités d’une économie empirique prétendument naturelle peut en effet stimuler l’anthropologie chrétienne dans sa réflexion sur la Loi naturelle parfois trop rapidement identifiée aux régularités de la biologie. Ce point de vue peut d’ailleurs trouver des appuis dans l’argument développé ici même par Geneviève Médevielle montrant que, selon Thomas d’Aquin, le juste prix n’est pas susceptible d’une détermination empirique simpliste, car il doit se conformer à la norme de justice que commande le « bien commun » de l’ensemble de la société comme fin ultime.
Comparison of Oral and Vaginal Administration of Low-dose Misoprostol for Labor Induction
Authors: Jyoti Ragweshwar , Mahajan Mamta , Gupta Kumud Bala , Sharma Renu 
Published: February 2013

ABSTRACT

Objective
Comparison of oral and vaginal administration of lowdose misoprostol for induction of labor at term.

Materials and methods
Two hundred pregnant women after 37 weeks of gestation with an indication for induction were given 25 μg of misoprostol orally (study group) or vaginally (control group), every 3 hours to a maximum of 8 doses. The induction to delivery interval, requirement of oxytocin, dose of misoprostol used, maternal and neonatal outcome were analyzed statistically.

Results
The median induction to delivery interval was significantly shorter in those induced with vaginal misoprostol (p = 0.06). The median induction to delivery interval was 21.35 ± 7.44 hours in study group and 14.64 ± 5.49 hours in control group. Eighty-two percent women in study group and 84% women in control group had vaginal delivery. Cesarean section rate was lower in control group, 16% vs 18% in study group, but the difference was not statistically significant (p = 0.790). Oxytocin augmentation was needed for 80% cases in the study group and 54% cases in control group, which was statistically significant (p = 0.006). The incidence of abnormal FHR was more in control group as compared to study group (30 vs 14%). Hyperstimulation syndrome was observed in 4% cases in control group and 2% cases in study group. Neonatal outcome was found to be similar in both groups.

Conclusion
Vaginal misoprostol achieved higher success rate within a short induction interval but was associated with increase in abnormal FHR pattern and abnormal uterine activity as compared to the oral route. Oral route had comparable efficacy, was safe and well-tolerated route of misoprostol administration for induction of labor at term.

Uterine Rupture: Changing Trends in Obstetrics and Lessons for Obstetricians
Authors: Rabbani Tamkin Khan , Zia Shumaila , Rafique Muhammad , Rizwan Ayesha , Amin Abdel Bagi 
Published: February 2013

ABSTRACT

Objectives
To determine the impact of improved obstetric care on the incidence, risk factors, management modalities and fetomaternal outcome of uterine rupture.

Materials and methods
Retrospective analysis of clinical records of uterine rupture cases at the department of Obstetrics and Gynecology, Abha General Hospital, Abha, KSA, from January 2007 to January 2012.

Outcome measures
Maternal and perinatal morbidity and mortality.

Results
Analysis showed 33 cases of uterine rupture among 34,590 deliveries, the incidence being 1/1048 (0.09%). Majority of the cases (73%) were unbooked. Important risk factors were previous cesarean section (88%) and grand multiparity (80%). Previous one C-section was also found to be an important risk factor (80%) for uterine rupture. Most of the patients were in their 30s. The frequency of complete and incomplete uterine rupture was almost the same (52 and 48% respectively). Total abdominal hysterectomy was required in 9 (27%), repair in 23 (70%) and one (3%) woman underwent subtotal hysterectomy. None of the patients agreed for tubal ligation. Seven (21%) cases were associated with bladder injury and three (9%) had vascular injury. There was no maternal mortality, 11 (33%) intrauterine fetal deaths and a live birth rate was 67%.

Conclusion
The absolute incidence of uterine rupture has not decreased inspite of the availability of ANC care and facilities for institutional deliveries. Only the etiological profile has changed. Our study found previous C-section as the most important emerging cause for uterine rupture. Reduction in Csection rate, awareness about the signs and symptoms of impending rupture, careful monitoring during induction in a scarred uterus on the part of caregivers and counseling about need for timely booking and importance of institutional delivery are important factors for reducing uterine rupture.

Peripartum Cardiomyopathy: A Review of Three Case Reports
Authors: Kumari Ankita , Chaturvedi Mridul 
Published: February 2013

ABSTRACTPeripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy that presents with heart failure secondary to left ventricular systolic dysfunction toward the end of pregnancy or in the months after delivery. Incidence of PPCM ranges from 1:300 to 1:15,000 pregnancies. Causes and pathogenesis are poorly understood. Clinical presentation includes signs and symptoms of heart failure. PPCM remains a major cause of maternal morbidity and mortality. Many cases of PPCM improve or resolve completely but others progress to heart failure; as early diagnosis and medical treatment may affect the patient's long-term prognosis. The aim of this report is to make health professionals aware of the possibilities in a woman with dyspnoea in the postpartum period.How to cite this articleKumari A, Singh S, Singh S, Chaturvedi M.

Natural weathering studies of biobased thermoplastic starch from agricultural waste/polypropylene blends
Authors: Pang Ming‐Meng , Pun Meng‐Yan , Ishak Zainal Arifin Mohd. 
Published: February 2013

AbstractThermoplastic starch (TPS) obtained from agricultural waste was blended with polypropylene (PP) for natural weathering studies. The agricultural waste material was obtained from seeds and tubers with a starch content of approximately 50%. Commercial‐grade TPS and native tapioca‐based TPS were also prepared for comparison. The biobased TPS/PP extruded sheets were exposed to natural weathering for six months and their deterioration in weight, tensile properties, thermal properties, and relative molecular weight were monitored. SEM micrographs revealed the formation of surface cracking and the presence of microorganisms. FTIR spectrum indicated an increase in the carbonyl index over time as a result of the formation of degradation products. TPS/PP blends made from agricultural waste showed a better resistance to natural weathering compared to the other high starch formulation. The higher starch content in the blend system encouraged the rapid degradation process due to the combined effect of UV radiation with oxidation, moisture, temperature, and microbial attack. © 2013 Wiley Periodicals, Inc.

DNAzyme‐Based Probes for Telomerase Detection in Early‐Stage Cancer Diagnosis
Authors: Wang Hui , Donovan Michael J. , Meng Ling , Zhao Zilong , Kim Youngmi , Ye Mao , Tan Weihong 
Published: February 2013

AbstractHuman telomerase is a polymerase enzyme that adds tandem repeats of DNA (TTAGGG) in the telomeric region to the ends of chromosomes. Since telomerase can be detected in immortalized, but not normal, somatic cells, it has been considered a selective target for cancer chemotherapy. Here, we describe a DNAzyme‐based probe to detect the presence of telomerase in cell lysates. Telomerase elongates the primer site on the probe. Subsequent addition of the PbII cofactor activates the DNAzyme, which cleaves the elongated fragment at the RNA site, releasing the probe for repetitive cycling and signal amplification. The cleaved fragment is detected by a reporter molecular beacon. Enzymatic amplification with rapid turnover allows detection of telomerase in the range of 0.1 to 1 μg cell lysate, with a fivefold increase in signal level for cancer cells over normal cells. This probe design can provide a simple, yet rapid and sensitive, measurement of telomerase activity.

Off the Beaten Track: The Use of Secondary Amines in the Ugi Reaction
Authors: Tron Gian Cesare 
Published: February 2013

AbstractAlthough the Ugi multicomponent reaction is more than 40 years old, there is still room for its application to the discovery of new multicomponent transformations, even within the constraints of its classic four‐reactant menu (aldehyde, amine, carboxylic acid, and isocyanide). Replacement of a primary amine with a secondary one thus allows the Mumm‐like rearrangement step to be avoided, freezing the reaction course at the stage of an imino‐anhydride intermediate susceptible to alternative nucleophilic trapping. Mainstream post‐transformation strategies can then add a further level of complexity. The potential of this approach to expedite access to molecular scaffolds of biological relevance and to create unprecedented chemical diversity is outlined.
Kimberlite eruptions as triggers for early Cenozoic hyperthermals
Authors: Patterson Michael V. , Francis Don 
Published: February 2013

AbstractThe early Cenozoic experienced at least three short but major hyperthermals associated with disruptions of the global carbon cycle. The largest among those, the Paleocene‐Eocene thermal maximum, was associated with a negative carbon isotopic excursion of ~ 2.5‰ that appears to be best explained by the thermal dissociation of methane hydrates due to an initial period of warming. The cause of the initial warming has been attributed to a massive injection of carbon (CO2 and/or CH4) into the atmosphere; however, the source of the carbon is as yet unknown. The emplacement of a large cluster of kimberlite pipes at ~56 Ma in the Lac de Gras region of northern Canada may have provided the carbon that triggered early warming in the form of exsolved magmatic CO2. Our calculations indicate that the estimated 900–1100 Pg of carbon required for the initial ~3°C of ocean water warming associated with the Paleocene‐Eocene thermal maximum could have been released during the emplacement of a large kimberlite cluster. The coeval ages of two other kimberlite clusters in the Lac de Gras field and two other early Cenozoic hyperthermals indicate that CO2 degassing during kimberlite emplacement is a plausible source of the CO2 responsible for these sudden global warming events.

AbstractThis study investigates processes of sediment generation in equatorial central Africa. An original, complete and integrated mineralogical‐geochemical database on silt‐sized sediments derived from different parent rocks (basalt, granite, gneiss, metapsammite, sandstone) along the East African Rift from 5°S in Tanzania to 5°N in Sudan is presented and used to assess the incidence of diverse factors controlling sediment composition (source‐rock lithology, geomorphology, hydraulic sorting, grain size, recycling), with particular emphasis on chemical weathering.
Laboratory observation of acoustic fluidization in granular fault gouge and implications for dynamic weakening of earthquake faults
Authors: Xia Kaiwen , Huang Sheng , Marone Chris 
Published: February 2013

AbstractSeveral lines of evidence, including remote triggering of earthquakes and modulation of seismic tremor by Earth tides, suggest that faults weaken when subject to shaking and dynamic stresses associated with the passage of seismic waves. However, the origin of such dynamic weakening is poorly understood. Here we explore the role of acoustic resonance for dynamic fault weakening using laboratory measurements. Experiments were conducted using a split Hopkinson pressure bar assembly, with dynamic stressing via impact loading. Samples were composed of crushed rock particles from mine tailings with a particle size distribution similar to that found in a natural fault gouge. We used pulse‐shaper techniques and carefully evaluated dynamic stresses recorded at the front and rear of the sample to ensure that dynamic force balance was satisfied. Our experiments document acoustic‐induced fluidization and dramatic dynamic weakening. Frictional strength and elastic modulus of a simulated fault gouge are reduced by a factor of 5–10 via acoustic fluidization. We find a threshold acoustic pressure for fluidization that varies systematically with gouge zone properties. Our observations could help explain dynamic fault weakening and triggering of earthquake fault slip by dynamic stressing.
Hysteretic nonlinear elasticity of Berea sandstone at low‐vibrational strain revealed by dynamic acousto‐elastic testing
Authors: Renaud G. , Rivière J. , Le Bas P.‐Y. , Johnson P.A. 
Published: February 2013

AbstractThrough changes in wave speed of ultrasonic pulses traversing the sample, we measure variations in the elasticity of dry Berea sandstone as a function of the applied low‐frequency (LF) axial strain (varied from 10−7 to 10−5). The approach, termed dynamic acousto‐elasticity, is the dynamic analog of static acousto‐elasticity where the wave speed is measured as a function of the applied static load. Dynamic acousto‐elasticity uses low‐frequency vibrational loading of smaller strain amplitude, typically below 10−4, and it includes inertial effects. At strain amplitudes around 10−6, compression and tension produce a material softening of the material. In contrast, a quasi‐static compression inducing a strain between 10−4 and 10−3 leads to a material stiffening. At 10−5 strain amplitude, elaborate hysteretic signatures of modulus strain are observed. The measurements provide the first direct experimental evidence of hysteretic nonlinear (wave amplitude dependent) elasticity in a sandstone at low dynamic strains.
Implications of Arctic sea ice changes for North Atlantic deep convection and the meridional overturning circulation in CCSM4‐CMIP5 simulations
Authors: Jahn Alexandra , Holland Marika M. 
Published: February 2013

AbstractUsing CCSM4 climate simulations for 1850–2300 with four different future forcing scenarios, we show that the maximum strength of the Atlantic meridional overturning circulation (MOC) decreases proportionally to the applied CO2 forcing. This weakening of the overturning is caused by a reduction or shut down of North Atlantic (NA) deep convection due to a surface freshening. In the Labrador Sea, the surface freshening is caused by strongly increased liquid freshwater exports from the Arctic, which are largely due to the decrease in the Arctic sea ice cover. In the strongest forcing scenario (RCP8.5), the Arctic becomes summer ice‐free by the end of the 21st century and year‐round ice‐free by the end of the 23rd century. As a result of the associated freshening, all NA deep convection ceases by 2145, which leads to a 72% (18 Sv) decrease of the MOC strength by the end of the simulation in 2300.
