Published: October 2012

SUMMARY

Objective
The aim of this study was to evaluate the two-year clinical performance of Class III, IV, and V composite restorations using a two-step etch-and-rinse adhesive system (2-ERA) and three one-step self-etching adhesive systems (1-SEAs).

Material and Methods
Two hundred Class III, IV, and V composite restorations were placed into 50 patients. Each patient received four composite restorations (Amaris, Voco), and these restorations were bonded with one of three 1-SEAs (Futurabond M, Voco; Clearfil S3 Bond, Kuraray; and Optibond All-in-One, Kerr) or one 2-ERA (Adper Single Bond 2/3M ESPE). The four adhesive systems were evaluated at baseline and after 24 months using the following criteria: restoration retention, marginal integrity, marginal discoloration, caries occurrence, postoperative sensitivity and preservation of tooth vitality. After two years, 162 restorations were evaluated in 41 patients. Data were analyzed using the χ2 test (p&lt;0.05).

Results
There were no statistically significant differences between the 2-ERA and the 1-SEAs regarding the evaluated parameters (p&gt;0.05).

Conclusion
The 1-SEAs showed good clinical performance at the end of 24 months.
The Evaluation of Dentinal Tubule Occlusion by Desensitizing Agents: A Real-time Measurement of Dentinal Fluid Flow Rate and Scanning Electron Microscopy
Authors: Kim SY , Kim EJ , Kim DS , Lee IB 
Published: October 2012

SUMMARY
The aims of this study were to examine changes in dentinal fluid flow (DFF) during the application of a desensitizing agent and to compare the permeability reduction levels among different types of desensitizing agents.
A cervical cavity was prepared for the exposure of cervical dentin on an extracted human premolar connected to a subnanoliter fluid flow measuring device under 20 cm of water pressure. The cavity was acid-etched with 32% phosphoric acid to make dentin highly permeable. The different types of desensitizing agents that were applied on the cavity were Seal&Protect as the light-curing adhesive type, SuperSeal and BisBlock as oxalate types, Gluma Desensitizer as the protein-precipitation type, and Bi-Fluoride 12 as the fluoride type. DFF was measured from the time before the application of the desensitizing agent throughout the application procedure to five minutes after the application. The characteristics of dentinal tubule occlusion of each desensitizing agent were examined by scanning electron microscopy.
The DFF rate after each desensitizing agent application was significantly reduced when compared to the initial DFF rate before application for all of the desensitizing agents (p&lt;0.05). Seal&Protect showed a greater reduction in the DFF rate when compared to Gluma Desensitizer and Bi-Fluoride 12 (p&lt;0.05). SuperSeal and BisBlock exhibited a greater reduction in DFF rate when compared to Bi-Fluoride 12 (p&lt;0.05).
The dentin hypersensitivity treatment effects of the employed desensitizing agents in this study were confirmed through real-time measurements of DFF changes. The light-curing adhesive and oxalate types showed greater reduction in the DFF rate than did the protein-precipitation and fluoride types.

Authors: Ju Li‐Ping , Shih Huei‐Chuan , Chiang Yu‐Chung 
Published: October 2012

• Premise of the study: Microsatellite primers were developed for the endangered species Fagus hayatae (Fagaceae) to investigate the genetic diversity of the population and to investigate species delimitation within Fagus.• Methods and Results: Ten polymorphic simple sequence repeat markers were developed for F. hayatae using a magnetic bead enrichment method. The primers amplified trinucleotides, hexanucleotides, and complex repeats with six to 16 alleles per locus. The observed and expected heterozygosities across loci varied, with a range of 0.05–0.71 and 0.63–0.91, respectively. Most of the primers also amplified DNA from F. crenata, F. grandifolia, F. japonica, F. longipetiolata, F. lucida, F. orientalis, and F. sylvatica.• Conclusions: These results indicate that these polymorphic loci of F. hayatae will be potentially useful for future studies of the population genetic diversity within the species. In addition, the interspecific amplification indicates that these transferable microsatellite markers will also be useful for future phylogeographic and speciation studies among close Fagus species.

Que nous apprennent sur la jeunesse ces textes ? Comment cette activité s’insère-t-elle parmi les autres goûts et pratiques des auteurs ? Les fiches de présentation des internautes qui s’inspirent des romans et des films, Harry Potter pour écrire leurs récits seront nos guides pour entrer dans ce domaine encore mal connu de la recherche française.
En attendant de « trouver sa place » : le chômage-intérim des jeunes diplômés
Authors: Papinot Christian 
Published: October 2012

Résumé À partir d’un récit biographique exemplaire qui sert de trame à l’article, il s’agit de donner à comprendre les significations de ce sas du chômage-intérim pour les jeunes diplômés dans leurs débuts de vie active. L’intérim se présente comme un choix par défaut, une sorte de « sas probatoire » d’entrée dans la vie active, à risques et aux fonctions mal définies. Dans une phase de transition professionnelle de plus en plus longue et chaotique, si l’objectif unanimement recherché est l’obtention d’un emploi stable dans un poste correspondant à sa qualification, l’emploi intérimaire en tant que substitut à un véritable emploi ne peut se présenter comme supportable que s’il est pensé comme provisoire. Cependant cette socialisation au travail contribue à déplacer les normes de la relation salariale car l’échange contribution/rétribution intègre désormais les mouvements dans l’emploi.
Le management bancaire des ouvertures de capital des entreprises françaises (1878-1881)
Authors: Petit-Konczyk Muriel 
Published: October 2012

Résumé Quel a été le rôle des établissements bancaires dans les ouvertures de capital des firmes pendant la courte période d’euphorie boursière de 1878 à 1881 ? Une sélection d’études de cas analyse leur rôle dans des opérations en capital de firmes présentant quatre types de motivations : la recherche du capital-risque, du capital-développement, du capital-transmission ou du capital-monopole. Les jeunes banques de l’époque maîtrisaient déjà des pratiques telles que le capital-réputation, le recyclage des capitaux dans les fenêtres d’opportunité du marché boursier, la distillation des capitaux étape par étape, lesquelles sont considérées comme des concepts modernes dans la littérature financière.
Quand l'actionnaire remplace le client et détruit sa propre valeur : le cas de Coca-Cola
Authors: Jacquet Dominique 
Published: October 2012

Résumé Les années 1980 ont vu se développer de manière spectaculaire le market for corporate control , et les marchés de capitaux se sont accordé le droit de punir les dirigeants incompétents et, pour le moins, de les mettre sous la menace d’une OPA hostile afin de les conduire à privilégier la valeur actionnariale sur tout autre objectif. La conséquence immédiate a été de faire entrer le marché dans la décision d’investissement de l’entreprise et de motiver cette dernière à adopter une stratégie et des indicateurs de performance dictés par le marché. Si, dans un premier temps, le processus a pu paraître bénéfique, les effets secondaires négatifs sont apparus avec un certain délai, les sociétés ayant parfois « oublié » que, sur le long terme, la valeur actionnariale ne pouvait se créer au détriment des parties prenantes (fournisseurs, employés, distributeurs). La trajectoire de Coca-Cola est une bonne illustration de ce phénomène. Au début des années 1980, la firme construit une stratégie opérationnelle dont le succès est immédiat et se reflète dans sa trajectoire boursière spectaculaire. Puis, prisonnière de son succès boursier, Coca-Cola va progressivement détourner la valeur générée dans sa relation avec les parties prenantes pour la transférer aux actionnaires. À la fin des années 1990, la société va entrer dans une période de crise et ne va créer aucune valeur actionnariale pendant 12 ans.

Introduction Sertoli-Leydig cell tumors (SLCTs) are rare tumors mostly occurring in young women. Here we report an unusual case of a SLCT with simultaneous occurrence of endometrioid adenocarcinoma of the endometrium in a woman in menopause. Case Report A 67-year-old woman presented with progressive signs of virilization. Blood tests showed increased levels of testosterone, delta-4-androstenedione, and dehydroepiandrosterone (DHEA). DHEA-sulphate, 17β-estradiol, estrone, and sex-hormone binding globulin serum levels were within the normal range. Magnetic resonance imaging revealed a solid mass of 2.7 × 2.9 cm in the right ovary set against the background of the uterus. The patient underwent bilateral salpingo-oophoretomy with hysterectomy. The mass in the right ovary was a differentiated SLCT. Incidentally, the endometrium revealed an endometrioid adenocacinoma. Following surgical treatment the plasma androgens dropped to normal levels, and signs and symptoms of virilization improved. Conclusion SLCT should be suspected in postmenopausal women who present rapid progressive androgen excess symptoms with hyperandrogenemia.
A Lattice Boltzmann and Immersed Boundary Scheme for Model Blood Flow in Constricted Pipes: Part 1 - Steady Flow
Authors: Fu S. C. , Leung W. W. F. , So R. M. C. 
Published: October 2012

AbstractHemodynamics is a complex problem with several distinct characteristics; fluid is non-Newtonian, flow is pulsatile in nature, flow is three-dimensional due to cholesterol/plague built up, and blood vessel wall is elastic. In order to simulate this type of flows accurately, any proposed numerical scheme has to be able to replicate these characteristics correctly, efficiently, as well as individually and collectively. Since the equations of the finite difference lattice Boltzmann method (FDLBM) are hyperbolic, and can be solved using Cartesian grids locally, explicitly and efficiently on parallel computers, a program of study to develop a viable FDLBM numerical scheme that can mimic these characteristics individually in any model blood flow problem was initiated. The present objective is to first develop a steady FDLBM with an immersed boundary (IB) method to model blood flow in stenoic artery over a range of Reynolds numbers. The resulting equations in the FDLBM/IB numerical scheme can still be solved using Cartesian grids; thus, changing complex artery geometry can be treated without resorting to grid generation. The FDLBM/IB numerical scheme is validated against known data and is then used to study Newtonian and non-Newtonian fluid flow through constricted tubes. The investigation aims to gain insight into the constricted flow behavior and the non-Newtonian fluid effect on this behavior.
A Lattice Boltzmann and Immersed Boundary Scheme for Model Blood Flow in Constricted Pipes: Part 2 - Pulsatile Flow

Published: October 2012

AbstractOne viable approach to the study of haemodynamics is to numerically model this flow behavior in normal and stenosed arteries. The blood is either treated as Newtonian or non-Newtonian fluid and the flow is assumed to be pulsating, while the arteries can be modeled by constricted tubes with rigid or elastic wall. Such a task involves formulation and development of a numerical method that could at least handle pulsating flow of Newtonian and non-Newtonian fluid through tubes with and without constrictions where the boundary is assumed to be inelastic or elastic. As a first attempt, the present paper explores and develops a time-accurate finite difference lattice Boltzmann method (FDLBM) equipped with an immersed boundary (IB) scheme to simulate pulsating flow in constricted tube with rigid walls at different Reynolds numbers. The unsteady flow simulations using a time-accurate FDLBM/IB numerical scheme is validated against theoretical solutions and other known numerical data. In the process, the performance of the time-accurate FDLBM/IB for a model blood flow problem and the ease with which the no-slip boundary condition can be correctly implemented is successfully demonstrated.

Published: October 2012

Abstract
OBJECTIVE. We evaluated the effects of occupation-based intervention on poststroke upper-extremity (UE) motor recovery, neuroplastic change, and occupational performance in 1 research participant.
METHOD. A 55-yr-old man with chronic stroke and moderately impaired UE motor function participated in 15 sessions of occupation-based intervention in a hospital setting designed to simulate a home environment. We tested behavioral motor function (Fugl-Meyer Assessment, Stroke Impact Scale, Canadian Occupational Performance Measure) and neuroplasticity (transcranial magnetic stimulation [TMS]) at baseline and at completion of intervention. We collected descriptive data on occupational participation throughout the study.
RESULTS. All behavioral outcomes indicated clinically relevant improvement. TMS revealed bihemispheric corticomotor reorganization. Descriptive data revealed enhanced occupational performance.
CONCLUSION. Occupation-based intervention delivered in a hospital-based, homelike environment can lead to poststroke neuroplastic change, increased functional use of the affected UE, and improved occupational performance.

AbstractOBJECTIVE. We examined the sensitivity of the Evaluation of Social Interaction (ESI) as a measure of the overall quality of social interaction in children as they engage in social exchanges in a natural context with typical social partners.METHOD. We compared the ESI measures of 23 children with disabilities with those of 23 children without disabilities, matched by age and gender.RESULTS. Paired t-test analysis revealed a statistically significant difference, t(22) = −4.065, p = .001, in the quality of social interaction for the two groups of children, indicating sensitivity of the ESI.CONCLUSION. The results support the use of the ESI to measure quality of social interaction in a natural context.

Abstract
To clarify expectations for mature cutting skills and investigate the influences of cutting task and scissor type, we videotaped 60 typical adults cutting three shapes with two different types of scissors. The videotapes were reviewed, and 38 aspects of grasp and cutting motions were rated. Percentages of participants who used a particular grip or cutting motion for each shape with each scissor type were reported and compared. Findings included variations in grasp that depended on the scissor type used and variations in cutting motions that depended on the shape being cut. Improved understanding of mature scissor skills and the effect of variations in the cutting task and scissor type used will allow more effective assessment of and intervention for children and adults with cutting difficulties. Specific implications for practice are discussed.

Authors: Hayner Kate A. 
Published: October 2012

AbstractOBJECTIVE. I evaluated the effectiveness of the California Tri-Pull Taping method for clients with poststroke inferior shoulder subluxation of the glenohumeral joint.METHOD. Ten participants were followed for 9 wk using an interrupted time series quasi-experimental single-subject ABA design to examine shoulder pain, activities of daily living (ADL) function, active range of motion, tape comfort, and subluxation.RESULTS. The California Tri-Pull Taping method decreased inferior subluxation significantly from baseline to intervention but not at postintervention. Active range of motion was significantly increased in shoulder flexion and abduction between the baseline and intervention and the intervention and postintervention phases. Functional ADL scores were significant. The taping was reported to be comfortable. No significant difference in pain was found.CONCLUSION. This intervention is a promising adjunct to the management of the hemiplegic subluxed shoulder that warrants further research.

Authors: Weiner Nikki Williamson , Toglia Joan , Berg Christine 
Published: October 2012

Abstract
OBJECTIVE. We piloted the Weekly Calendar Planning Activity (WCPA), a performance-based measure of executive function (EF), to establish a baseline for at-risk adolescents.
METHOD. Participants were 113 youths ages 16–21 who were enrolled at a charter school for youth returning to high school after dropping out. We administered the WCPA and collected demographic information.
RESULTS. On average, participants spent 15.9 min on the WCPA, made 7.9 errors, and followed 4.0 of 5 possible rules. No ceiling effect was observed in overall accuracy. Participants used a mean of 3.1 strategies (standard deviation = 1.9) while completing the WCPA. Participants who used more strategies spent more time planning and completing the task and were more accurate.
CONCLUSION. The WCPA may be useful to occupational therapists as a performance measure of EF. This assessment allows evaluation of complex task performance, strategy use, self-evaluation of performance, and error patterns, which can be used in developing intervention strategies.
