L'injonction d'être sujet dans la société hypermoderne : la psychanalyse et l'idéologie de la réalisation de soi-même
Authors: de Gaulejac Vincent 
Published: October 2011

Résumé « La psychanalyse s’intéresse au social » écrivent les auteurs de l’argument de ce numéro. Il en va de même pour la sociologie qui s’intéresse à la psychanalyse, à la fois comme pratique sociale et comme théorie qui apporte des clés de compréhension sur la dimension psychique des phénomènes sociaux. Si l’individu est le produit d’une histoire, cette histoire condense l’ensemble des facteurs sociaux et historiques qui interviennent dans le processus de socialisation et l’ensemble des facteurs intrapsychiques qui contribuent au développement de la personne. Loin de s’opposer, le social et le psychique, quand bien même ils obéissent à des lois propres, s’étayent et se nouent dans des combinaisons multiples et complexes.

Abstract
Group A Streptococcus (GAS) causes diverse infections in humans, ranging from mild to life-threatening invasive diseases, such as necrotizing fasciitis (NF), a rapidly progressing deep tissue infection. Despite prompt treatments, NF remains a significant cause of morbidity and mortality, even in previously healthy individuals. The early recruitment of leukocytes is crucial to the outcome of NF; however, although the role of polymorphonuclear neutrophils (PMNs) in host defense against NF is well established, the role of recruited macrophages remains poorly defined. Using a cutaneous murine model mimicking human NF, we found that mice deficient in TNF-α were highly susceptible to s.c. infections with GAS, and a paucity of macrophages, but not PMNs, was demonstrated. To test whether the effects of TNF-α on the outcome of infection are mediated by macrophages/monocytes, we systemically depleted C57BL/6 mice of monocytes by pharmacological and genetic approaches. Systemic monocyte depletion substantially increased bacterial dissemination from soft tissues without affecting the number of recruited PMNs or altering the bacterial loads in soft tissues. Enhanced GAS dissemination could be reverted by either i.v. injection of monocytes or s.c. administration of peritoneal macrophages. These experiments demonstrated that recruited macrophages play a key role in defense against the extracellular pathogen GAS by limiting its spread from soft tissues.

Introduction Central venous catheterization plays an important role in the treatment of emergency patients who require renal replacement therapy. Emergency patients with end-stage renal disease are at high risk for development of complications because of coagulation disorders, tissue, and organ changes due to uremia, anatomic variations, and obstruction of the large central veins. Complications associated with catheter placement can be mechanical, infectious, and thrombotic, and may occur during or following insertion of central venous catheterization which is a life-saving procedure for patients. Case presentation We report a case of respiratory arrest in a 76-year-old woman suffering from end-stage renal disease for 14 years, because of large soft tissue subcutaneous hematoma in the right upper thoracic outlet. The rapid development of hematoma was a consequence of arterial bleeding from the branch of the thyreocervical trunk. Laceration of the thyreocervical trunk branch during central venous catheterization is a rare complication. Later diagnostic images revealed catheter perforation of confluence of sinuses which also complicated this case. We briefly discuss signs, symptoms, and management of the patient. Conclusion Although arterial puncture of the carotid artery during the Seldinger technique is well-known life-threatening complication which can be recognized by light red pulsatile blood during aspiration, smaller arteries such as the thyreocervical trunk branch can be punctured during the procedure and lead to serious complications.
Fourth Annual Logistics Faculty Salary Survey

Published: October 2011

AbstractWhile the Association to Advance Collegiate Schools of Business (AACSB) International conducts an annual survey of business school faculty and administrative salaries, the standard reporting does not specify salary figures for logistics (and related areas such as supply chain management) faculty. Since the growth in the number of logistics faculty positions has continued to exceed the output of doctoral programs in the field for more than a decade, it is logical to assume that logistics faculty salaries, at all levels, are increasing. However, without factual data, questions such as what salary should a new logistics PhD expect, and what should an administrator budget for a logistics faculty position, cannot be answered satisfactorily. Moreover, everyone expects and wants to be adequately compensated. However, for the specific discipline of logistics and supply chain management (SCM), the data on average compensation across different ranks, institutions, and other such factors is not available. In order to provide such factual data, the authors have developed a survey to collect annual data on logistics and supply chain faculty salaries. This year’s survey was the fourth in the past five years.
Improving Freight Roadway Transportation with Dedicated Truck Lanes: Opportunities and Issues
Authors: Bucklew Keith J. 
Published: October 2011

AbstractDedicated truck lanes are a concept with inherent characteristics that can be the solution to a significant portion of the freight roadway transportation issues. The separation of trucks and automobiles through revised design configurations and operational features could reduce congestion, enhance mobility, and improve safety for all users of the infrastructure. This article examines the major issues of truck freight mobility and the need to develop roadway infrastructure differently to serve the complex supply chains and our economy. A public‐private partnership can be the financial engine to support this project with the necessary capital to fund the infrastructure. The benefits to the public are many and such a project can serve as the catalyst and cornerstone to a new way forward for freight mobility.

Authors: YİĞİT ÖZER Senem , ADIGÜZEL Özkan , KAYA Sadullah 
Published: October 2011

Aim: Debridement during root canal treatment is mandatory and it is provided by means of chemomechanical instrumentation and irrigation methods. This article analysis the debridement capacity of a novel system, SAF and its special irrigation device when used with different operation times in curved root canals.
Methodology: 30 mesiobuccal root canals of maxillary molars were instrumented using SAF. Teeth were divided into three groups. In Group 1, 10 new SAF files were used for operation for 4 minutes. In Group 2, the 4-min previously used SAF files were operated in the same manner. In Group 3, the 8-min previously used SAF files were operated. During SAF operation 2.6 % NaOCl and 17 % EDTA were used alternately in all groups. Debris and smear layer removal were evaluated for the apical thirds under scanning electron microscope.
Results: Non-used, 4-min preused, and 8-min preused SAF efficiently removed debris and smear layer in the apical thirds. There were no significant difference among the groups in terms of debridement.
Conclusions: When SAF is operated in curved root canals with continous flow of irrigation it results in debris and smear-free canal walls in the critical apical thirds within 12 minutes.

Contemporary Permanent Luting Agents Used in Dentistry: A Literature Review
Authors: SÜMER Ebru , DEĞER Yalçın 
Published: October 2011

Dental cements are widely used in dentistry. Base material, temporary filling material and luting agents can all have different clinical applications. Different types of cement have also been developed for various orthodontic and endodontic treatments.
In literature it is still argued that there is not ideal cement answering all purposes yet, so different materials are required for the comprehensive patient treatments and it is not always that easy to make the best choice.
The aim of this article is to provide a clinically relevant discussion of contemporary permanent luting agents, in order to enhance the dentist’s ability to make proper cementation choices and application.

Equilibrium swelling studies and dye sorption characterization of AAm/SA hydrogels cross‐linked by PEGDMA and semi‐IPNs with PEG
Authors: ÜzüM ÖMer Bariş , Karadag Erdener 
Published: October 2011

AbstractHere, a novel ternary semi‐interpenetrating polymer networks (semi‐IPNs) were prepared by introducing poly (ethylene glycol), (PEG) into acrylamide/sodium acrylate, (AAm/SA) hydrogels. Water uptake and dye sorption properties of AAm/SA hydrogels and AAm/SA/PEG semi‐IPNs were investigated as a function of chemical composition of the hydrogels. Inclusion of hydrophilic monomer in the acrylamide hydrogels caused high swelling capacity and better absorbency for cationic dye molecules. FTIR spectroscopy was used to identify the presence of different repeating units in the semi‐IPNs. For swelling characterization, swelling experiments were performed in water at 25°C, gravimetrically. Some swelling and diffusion characteristics were calculated for different semi‐IPNs and hydrogels prepared under various formulations. AAm/SA hydrogels and AAm/SA/PEG semi‐IPNs were used in experiments on sorption of water‐soluble cationic dye such as “Janus Green B'' (JGB). For sorption of JGB, the polymeric systems were studied by batch sorption technique at 25°C. Hydrogels and semi‐IPNs developed in this study may serve as a potential device for super water retainer and sorbent for removal of some agents and dye molecules. The utilization of these types of materials, in pharmaceuticals, agriculture, biotechnology, environment, separation, purification, and immobilization makes hydrogels more popular. © 2011 Wiley Periodicals, Inc.

Novel pyridine‐based poly(urethane‐urea) elastomers with several different cross‐linkers in the hard segment structure
Authors: Oprea S. , Potolinca V. O. , Buruiana E. C. 
Published: October 2011

AbstractLinear and cross‐linked poly(urethane‐urea) elastomers were synthesized from hydroxyl‐terminated polyether and 1,6‐hexane diisocyanate with different 2‐amino‐3‐hydroxypyridine content or cross‐linkers, by solution polymerization. The polymers were characterized by FT‐IR spectroscopic method. The thermogravimetric analysis (TGA) showed good thermal stability (10% weight loss temperatures are in the range of 340–370°C). The obtained poly(urethane‐urea) elastomers also exhibited good mechanical properties with tensile strength of 10–22 MPa and elongation at break of 600%–1100%. It was found that a high content of 2‐amino‐3‐hydroxypyridine moiety within the hard segments of the linear poly(urethane‐urea) leads to decreased mechanical properties (such as the stress at break). Aside from the effect of the chemical cross‐links, the cross‐linker structure enhanced or disrupted the physical cross‐links, which determined high variation of the mechanical properties. © 2011 Wiley Periodicals, Inc.

Mixed convection in a doubly stratified micropolar fluid saturated non‐Darcy porous medium
Authors: Srinivasacharya D. , RamReddy Ch. 
Published: October 2011

AbstractThe effects of thermal and solutal stratification on mixed convection along a vertical plate embedded in a micropolar fluid saturated non‐Darcy porous medium are analysed. The nonlinear governing equations and their associated boundary conditions are initially cast into dimensionless forms by pseudo‐similarity variables. The resulting system of equations is then solved numerically using the Keller‐box method. The numerical results are compared and found to be in good agreement with previously published results as special cases of the present investigation. The velocity, microrotation, temperature and concentration profiles are shown for different values of the coupling number, non‐Darcy parameter, mixed convection parameter, thermal and solutal stratification parameters. The numerical values of the skin friction, wall couple stress, heat and mass transfer rates for different values of governing parameters are also tabulated. © 2011 Canadian Society for Chemical Engineering
Efficient Multi‐component Synthesis of Highly Substituted Imidazoles Utilizing P2O5/SiO2 as a Reusable Catalyst
Authors: Shaterian Hamid Reza , Ranjbar Mohammad , Azizi Kobra 
Published: October 2011

AbstractPhosphorus pentoxide supported on silica gel (P2O5/SiO2) has been used as an efficient and reusable catalyst for the one‐pot pseudo four‐component synthesis of 2,4,5‐trisubstituted imidazoles from benzil or benzoin, aldehydes, and ammonium acetate. It was also used for four‐component preparation of 1,2,4,5‐tetrasubstituted imidazoles from benzil or benzoin, aldehydes, primary amine, and ammonium acetate under thermal solvent‐free conditions. The remarkable features of this new procedure are high conversions, cleaner reaction, simple experimental and work‐up procedures and also the catalyst can be easily separated from the reaction mixture and reused several times without any loss of its activity.

Temperature‐induced Molecular Chain Motions of Styrenic Triblock Copolymers Studied by Intrinsic Fluorescence Spectra
Authors: Yuan Zhongke , Yang Dacheng , Fan Li 
Published: October 2011

AbstractThe temperature‐induced molecular chain motions of styrenic triblock copolymers (SBC), i.e. polystyrene‐block‐polybutadiene‐block‐polystyrene (SBS) and polystyrene‐block‐poly(ethylene‐co‐1‐butene)‐block‐polystyrene (SEBS), were studied by intrinsic fluorescence method. For SBS, the glass transition temperatures (Tgs) of B block and S block obtained by intrinsic fluorescence method were in good agreement with differential scanning calorimetry measurements (DSC). In the case of SEBS, an isoemission point was observed at about 310 nm at elevated temperatures, suggesting the slight conversion between the monomer and excimer emission. On this basis, the molecular chain motion of SEBS was monitored by both fluorescence intensity and excimer/monomer fluorescence ratio. Besides the Tgs of S block and EB blocks, a melting point (Tm) of weak crystalline in EB block was unambiguously determined by intrinsic fluorescence. Furthermore, it was found that the melting process directly led to the slight loosening of PS segments in interface and consequently the reduction of the amount of excimer. A reasonable mechanism was proposed to describe the molecular chain movements and phase transitions of SEBS upon heating. Moreover, the influence of temperature on the apparent activation energy of non‐radiative process (EaT) around Tg of S block was much stronger than that around Tg of B or EB blocks.
Characterization of cell lysis events on a microfluidic device for high‐throughput single cell analysis
Authors: Hargis Amy D. , Alarie Jean Pierre , Ramsey John Michael 
Published: October 2011

AbstractA microfluidic device capable of rapidly analyzing cells in a high‐throughput manner using electrical cell lysis is further characterized. In the experiments performed, cell lysis events were studied using an electron multiplying charge coupled device camera with high frame rate (>100 fps) data collection. It was found that, with this microfluidic design, the path that a cell follows through the electric field affects the amount of lysate injected into the analysis channel. Elimination of variable flow paths through the electric field was achieved by coating the analysis channel with a polyamine compound to reverse the electroosmotic flow (EOF). EOF reversal forced the cells to take the same path through the electric field. The improved control of the cell trajectory will reduce device‐imposed bias on the analysis and maximizes the amount of lysate injected into the analysis channel for each cell, resulting in improved analyte detection capabilities.
Cellular senescence and tumor suppressor gene p16
Authors: Rayess Hani , Wang Marilene B. , Srivatsan Eri S. 
Published: October 2011

AbstractCellular senescence is an irreversible arrest of cell growth. Biochemical and morphological changes occur during cellular senescence, including the formation of a unique cellular morphology such as flattened cytoplasm. Function of mitochondria, endoplasmic reticulum and lysosomes are affected resulting in the inhibition of lysosomal and proteosomal pathways. Cellular senescence can be triggered by a number of factors including, aging, DNA damage, oncogene activation and oxidative stress. While the molecular mechanism of senescence involves p16 and p53 tumor suppressor genes and telomere shortening, this review is focused on the mechanism of p16 control. The p16‐mediated senescence acts through the retinoblastoma (Rb) pathway inhibiting the action of the cyclin dependant kinases leading to G1 cell cycle arrest. Rb is maintained in a hypophosphorylated state resulting in the inhibition of transcription factor E2F1. Regulation of p16 expression is complex and involves epigenetic control and multiple transcription factors. PRC1 (Pombe repressor complex (1) and PRC2 (Pombe repressor complex (2) proteins and histone deacetylases play an important role in the promoter hypermethylation for suppressing p16 expression. While transcription factors YY1 and Id1 suppress p16 expression, transcription factors CTCF, Sp1 and Ets family members activate p16 transcription. Senescence occurs with the inactivation of suppressor elements leading to the enhanced expression of p16.

AbstractTo identify prognostic markers in nonmuscle invasive bladder cancer (NMIBC), the combined effect of RUNX3 and MGC17624 for predicting NMIBC progression was assessed. RUNX3 promoter methylation was examined using methylation specific‐polymerase chain reaction (MS‐PCR). MGC17624 mRNA expression was evaluated by real‐time PCR. Patients were divided into three groups according to the status of the two genes and the prognostic effects of these markers were evaluated. The median follow‐up period was 57.8 months (range, 9.1–189.7). The mRNA expression level of MGC17624 was significantly lower in patients with positive RUNX3 methylation than in those with negative methylation (p = 0.047). Kaplan–Meier estimates showed significant differences in time‐to‐progression between the genetic combination predictors (log‐rank test; p < 0.001). Patients with a poor predictive combination were at a significantly higher risk for progression [Hazard ratio (HR), 22.579] than patients with a good predictive combination in multivariate Cox regression analysis. In the subgroup analysis, a poor predictive combination accurately estimated progression in patients with intravesical therapy (HR, 20.081) and in those who experienced recurrence (HR, 54.233). Assessment of the status of RUNX3 and MGC17624 in combination was identified as a reliable method for predicting NMIBC progression.
