Published: February 2014

SUMMARY
This study evaluated the effects of simulated hydrostatic pulpal pressure (SPP) on the microtensile bond strength (μTBS) to dentin and nanoleakage patterns produced by self-adhesive luting agents after 12 months. Three self-adhesive luting agents (RelyX Unicem [UN], RelyX U100 [UC], and Clearfil SA Luting [SA]) and three conventional luting agents (Rely X ARC [RX], Panavia F [PF], and a two-step self-etching adhesive system [Clearfil SE Bond] associated with Panavia F [PS]) were evaluated. One hundred twenty-three human molars were abraded to expose occlusal surfaces. Resin cements were used to lute cylindrical composite blocks to the teeth either subjected or not to SPP. Sixty specimens were subjected to 15 cm H2O of SPP for 24 hours before and 24 hours or 12 months after cementation procedures. Afterward, restored teeth were serially sectioned into beams with a cross-sectional area of 1 mm2 at the bonded interface and were tested in tension (cross-head speed of 1 mm/min). Failure mode was determined using scanning electron microscopy (SEM). Data were statistically analyzed by three-way analysis of variance and post hoc Tukey test (p=0.05). Two additional teeth in each group were serially sectioned into 0.9-mm-thick slabs, which were submitted to a nanoleakage protocol with AgNO3 and analyzed with scanning and transmission electron microscopes. The μTBS values of the etch-and-rinse group (RX) were negatively influenced by SPP and long-term water storage with SPP. After 12 months, UC and SA presented premature failures in all specimens when submitted to SPP. SPP increased silver deposition in most groups in both evaluation times. The hydrostatic pulpal pressure effect was material dependent. The storage time without SPP did not affect bond strength. However, long-term SPP influenced the performance of the etch-and-rinse and self-adhesive cements regarding μTBS and nanoleakage pattern, except to UN.
Allelic isoforms of the chicken and duck histone H1.a
Authors: Górnicka-Michalska Ewa , Kowalski Andrzej , Pałyga Jan 
Published: February 2014

AbstractTwo isoforms of the erythrocyte histone H1.a were identified in two conservative flocks of Rhode Island Red chickens and six conservative flocks of ducks. The H1.a1 and H1.a2 isoforms formed three phenotypes (a1, a2 and a1a2) and were electrophoretically similar in the two species. The frequency of phenotype and histone H1.a allele occurrence varied within the genetic groups of birds, but the relatively rare allele a 2 was only detected in chicken and duck strains with colored feathers. Using mass spectrometry, we established that the difference between the measured masses of the duck H1.a isoforms was 156 Da. Since this value corresponds to the mass of the arginine residue alone or to the combined mass of the valine and glycine residues, we believe that the polymorphism of duck histone H1.a might have originated from sequence variation. A mass difference of 1 Da observed between chicken H1.a isoforms corresponded well to the previously detected Glu/Lys substitution (0.9414 Da) at position 117.

Aims: This study was done to evaluate the effectiveness of subcutaneous injection of sterile water compared with placebo in reduction of labor pain. Methods: Two hundred and forty pregnant women at term planned for normal vaginal delivery during the first stage of labor were randomized to receive either subcutaneous injection of sterile water (study group, n=120) or normal saline as placebo (control group, n=120) at painful point in lumbosacral region. Pain score was measured before and 10, 45 and 90 minutes after the injections. Main outcome measured was reduction of low back labor pain using visual analogue scale. Results: The mean pain score was equal in both groups prior to the injection. The pain scores were significantly lower among the intervention group compared to the control group at 10, 45, 90 minutes after injection. There was no difference between the two groups with regard to rate of instrumental delivery, cesarean rate and neonatal outcome.Conclusions: The subcutaneous injection of sterile water administered at painful point in lumbosacral area was effective in reducing low back labor pain during labor.

Published: February 2014

Abstract
The features of inclusions and microstructure for Ti-added carbon structural steel (C: 0.26 wt.-%) were studied by scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). After etching, it has been found that the titanium oxide can act as nucleation site for acicular ferrite. Moreover, from the SEM-EDS mapping images, it can be seen that the MnO-SiO2 phase occupies the core of nucleation inclusion, and the titanium oxide precipitates on them. This result can be explained by theoretical calculation, and this kind of precipitation does not lead to inclusion coarsening. Furthermore, the element sulfur accumulates on the periphery of nucleation oxides, which implies the absorption of MnS plays an important role for the acicular ferrite formation. These results confirm that titanium oxide precipitate can also induce the acicular ferrite formation, and may gain new insights in the oxide metallurgy.

Abstract
Red mud is a waste generated by the aluminium industry and its disposal is a major problem. Red mud waste from Eti Seydişehir aluminium plant of Turkey was considered as a hazardous waste for the environment and human health. The storage of the red mud is difficult due to its high amount of various metal oxides, elements and caustic content. In this study, the environmental compliance tests of the produced construction products of red mud were done and evaluated according to the >Regulation on Regularly Storage of Waste in Turkey<. According to the test results red mud, a hazardous waste alone, can be used in the construction products production. The construction products produced with red mud do not contain hazardous substances and thus, fit the requirements of the >Regulation on Regularly Storage of Waste in Turkey<.

En s’appuyant sur des méthodes de collecte et d’analyse informationnelle, on peut élaborer des « futurs probables », anticiper les mutations et prévoir leurs effets. C’est là que réside la différence entre la prospective et la futurologie, ou encore la science-fiction. La prospective, comme l’intelligence économique, met la connaissance au service de l’action stratégique et de la décision. Nous voudrions ainsi, dans le cadre de ce dossier, réconcilier prospective et futurologie, « ces deux sœurs ennemies affairées à sonder l’avenir » 1 , afin d’imaginer des scénarios pour l’évolution du paysage informationnel et des métiers qui y sont liés.

Les questions ouvertes par vos correspondants ont été refermées depuis la fin de 2012. Le Parti et l’État sont parvenus à mettre la conjoncture économique sous contrôle au prix d’un renforcement de la censure, d’un étouffement des mouvements sociaux et d’un semblant de redistribution. Mais pour la Chine, l’essentiel, ce sont les marchés extérieurs. Une économie dans laquelle les ménages épargnent la moitié de leurs gains n’est pas fondée sur la consommation de masse. C’est l’État qui a su gérer la formidable augmentation des investissements dans les infrastructures et le bâtiment, dont profite surtout l’élite. La question de l’environnement est nouvelle et fait peur ; elle est traitée en termes de responsabilité individuelle.
Économie de l'attention et nouvelles exploitations numériques
Authors: Citton Yves 
Published: February 2014

Cet article fait le point sur quelques nouvelles formes d’exploitation rendues possibles par Internet. Des travailleurs intellectuels sont mis en concurrence directe depuis les quatre coins de la terre ; le travail gratuit fourni par des fans ou des bloggeurs se trouve récupéré dans des entreprises commerciales ; l’internaute auquel on fournit un service gratuit se trouve devenir lui-même la marchandise dont des multinationales tirent leurs profits. À l’horizon de ces nouvelles exploitations apparaît la reconfiguration générale induite par le déploiement d’une économie de l’attention.

Matteo Pasquinelli dénonce l’idéologie « digitaliste » qui fait naïvement d’Internet un espace ouvert d’émancipation et d’égalité. Une telle vue ignore les asymétries et les parasitismes dont se nourrissent les nouvelles formes de capitalisme. Copyleft, creative commons et échanges de pair-à-pair doivent entre analysés de façon critique comme contribuant à de nouvelles formes d’exploitation de nos forces productives communes. De nouveaux outils plus discriminants, comme le copyfarleft de Dmytri Kleiner, doivent être mis au point pour rediriger la puissance commune des internautes vers le soin des communs.
Capitalisme mental

Published: February 2014

La publicité constitue une forme d’occupation et d’exploitation de notre ressource la plus précieuse, notre attention, laquelle est en passe de devenir une forme de capital tout aussi déterminante dans nos logiques socio-économiques que la forme argent. Les technologies de l’attraction développées à une échelle industrielle par les mass-medias (d’abord analogiques, puis désormais numériques) entraînent la mise en place d’un nouveau type de « capitalisme mental ». Dans cet article qui résume l’ouvrage qu’il lui a consacré, Georg Franck propose toute une batterie de concepts et de principes, à la fois puissants et fins, pour analyser les nouveaux modes d’exploitation et les nouvelles sources de conflits sociaux qui se mettent en place à cette occasion.
Des placeurs sachant se placer ?
Authors: Bense Ferreira Alves Celia 
Published: February 2014

À partir de l’analyse des rétributions du placement dans un théâtre parisien de grande renommée, cet article interroge le rapport des ouvreurs à leur implication organisationnelle et étudie les conditions de passage d’un « petit boulot » à un métier. Attirés par les rétributions directes de ce emploi de bas statut, les placeurs maintiennent leur participation sur la durée, car ils prennent un pari annexe externe : être embauchés dans un métier du secteur culturel de meilleur statut. Pour ceux qui souhaitent devenir comédiens ou metteurs en scène, le placement offre de nombreuses rétributions indirectes en lien avec ces métiers ce qui les amène à redéfinir leur pari et miser sur une embauche au sein de l’organisation, à savoir prendre un pari annexe interne . Ceci conforte ainsi la cohérence des lignes d’activité et donc leur implication dans l’organisation mais peut les éloigner de la réalisation de la carrière professionnelle visée.
« Ça n'a pas de prix »

Published: February 2014

Cet article expose les formes de rétributions non monétaires observées chez des céramistes et autres artisans d’art, dans des espaces du travail indépendant, en marge des mondes de l’art les plus légitimes. La relative précarité économique de ces professionnels s’accompagne d’une quête de bonheur dans le travail qui semble évacuer, du moins en partie, la question du profit marchand. Réduire cette situation à une dénégation de l’économie et à une forme d ’illusio vocationnelle paraît impropre à restituer la « double vérité », objective et subjective, du rapport au travail de ces indépendants. En prenant au sérieux le sens que ces enquêtés donnent à leur activité, on montre qu’ils pensent les rétributions du travail dans toute la diversité de leurs formes. Cet article expose ainsi à quelles conditions le revenu pécuniaire s’articule alors avec d’autres types de bénéfices, qu’il s’agisse de la valeur axiologique du travail (travail de belle facture, artifié) ou d’une « qualité de vie » liée aux espaces et aux temps du travail.
Psychological Stress in Children May Alter the Immune Response

Abstract
Psychological stress is a public health issue even in children and has been associated with a number of immunological diseases. The aim of this study was to examine the relationship between psychological stress and immune response in healthy children, with special focus on autoimmunity. In this study, psychological stress was based on a composite measure of stress in the family across the domains: 1) serious life events, 2) parenting stress, 3) lack of social support, and 4) parental worries. PBMCs, collected from 5-y-old high-stressed children (n = 26) and from 5-y-old children without high stress within the family (n = 52), from the All Babies In Southeast Sweden cohort, were stimulated with Ags (tetanus toxoid and β-lactoglobulin) and diabetes-related autoantigens (glutamic acid decarboxylase 65, insulin, heat shock protein 60, and tyrosine phosphatase). Immune markers (cytokines and chemokines), clinical parameters (C-peptide, proinsulin, glucose), and cortisol, as an indicator of stress, were analyzed. Children from families with high psychological stress showed a low spontaneous immune activity (IL-5, IL-10, IL-13, IL-17, CCL2, CCL3, and CXCL10; p &lt; 0.01) but an increased immune response to tetanus toxoid, β-lactoglobulin, and the autoantigens glutamic acid decarboxylase 65, heat shock protein 60, and tyrosine phosphatase (IL-5, IL-6, IL-10, IL-13, IL-17, IFN-γ, TNF-α, CCL2, CCL3, and CXCL10; p &lt; 0.05). Children within the high-stress group showed high level of cortisol, but low level of C-peptide, compared with the control group (p &lt; 0.05). This supports the hypothesis that psychological stress may contribute to an imbalance in the immune response but also to a pathological effect on the insulin-producing β cells.
Three Tapasin Docking Sites in TAP Cooperate To Facilitate Transporter Stabilization and Heterodimerization
Authors: Leonhardt Ralf M. , Abrahimi Parwiz , Mitchell Susan M. , Cresswell Peter 
Published: February 2014

Abstract
The TAP translocates peptide Ags into the lumen of the endoplasmic reticulum for loading onto MHC class I molecules. MHC class I acquires its peptide cargo in the peptide loading complex, an oligomeric complex that the chaperone tapasin organizes by bridging TAP to MHC class I and recruiting accessory molecules such as ERp57 and calreticulin. Three tapasin binding sites on TAP have been described, two of which are located in the N-terminal domains of TAP1 and TAP2. The third binding site is present in the core transmembrane (TM) domain of TAP1 and is used only by the unassembled subunits. Tapasin is required to promote TAP stability, but through which binding site(s) it is acting is unknown. In particular, the role of tapasin binding to the core TM domain of TAP1 single chains is mysterious because this interaction is lost upon TAP2 association. In this study, we map the respective binding site in TAP1 to the polar face of the amphipathic TM helix TM9 and identify key residues that are essential to establish the interaction. We find that this interaction is dispensable for the peptide transport function but essential to achieve full stability of human TAP1. The interaction is also required for proper heterodimerization of the transporter. Based on similar results obtained using TAP mutants that lack tapasin binding to either N-terminal domain, we conclude that all three tapasin-binding sites in TAP cooperate to achieve high transporter stability and efficient heterodimerization.
Unexpected resurgence of a large submersed plant bed in Chesapeake Bay: Analysis of time series data
Authors: Gurbisz Cassie , Kemp W. Michael 
Published: February 2014

An historically large (> 50 km2) submersed plant bed in upper Chesapeake Bay virtually disappeared in 1972, following Tropical Storm Agnes. The bed experienced little regrowth until the early 2000s, when plant abundance rapidly increased. Here, we analyze a suite of recent (1984–2010) and historical (1958–1983) time series datasets to assess alternative explanations for the submersed plant resurgence. Change‐point analysis showed that spring nitrogen (N) loading increased from 1945 to 1988 and decreased from 1988 to 2010. Analysis of variance on recent time series showed a significant difference in submersed aquatic vegetation (SAV) abundance percent change during wet years (−7 ± 11%) and dry years (53 ± 20%), indicating that floods and droughts likely contributed to SAV loss and growth, respectively. In the historic dataset, however, increasingly poor water quality led to SAV loss despite an extended drought period, indicating that underlying water quality trends were also important in driving change in SAV abundance. Several water quality variables, including N concentration and turbidity, were lower inside the SAV bed than outside the SAV bed, implying the presence of feedback processes whereby the bed improves its own growing conditions by enhancing biophysical processes such as sediment deposition and nutrient cycling. Together, these analyses suggest that stochastic extremes in river discharge and long‐term water quality trends synergistically facilitated sudden shifts in SAV abundance and that feedback processes likely reinforced the state of the bed before and after the shifts. Management efforts should consider these dynamic interactions and minimize chronic underlying stressors, which are often anthropogenic in origin.
Periodontal Status in Subjects with Hyperlipidemia and Determination of Association between Hyperlipidemia and Periodontal Health: A Clinicobiochemical Study
Authors: Patil Veena A , Desai Manthan H , Shivakumar TP 
Published: February 2014

ABSTRACT

Aim
The aim of this study was to assess the periodontal status in subjects with hyperlipidemia and to determine whether there is any association between hyperlipidemia and periodontitis.

Materials and methods
Sixty subjects with hyperlipidemia and 60 normolipidemic subjects participated in the study. Biochemical parameters assessed included plasma triglyceride, total cholesterol, low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) levels. Periodontal parameters assessed included plaque index (PI), probing depth (PD), clinical attachment level (CAL) and percentage of sites with bleeding on probing (BOP).

Results
Hyperlipidemic patients showed significantly higher values across the four periodontal parameters. Plasma triglycerides, total cholesterol, LDL-C were significantly and positively associated with PD, BOP and CAL (p = 0.05). Whereas HDL-C levels were significantly and negatively associated with PD, BOP and CAL (p = 0.05).

Conclusion
Patients with hyperlipidemia manifested higher values of periodontal parameters compared to control group. Poorly controlled hyperlipidemia had a destructive impact on periodontium. A cyclic relationship exists between serum lipids, periodontitis and systemic health.

Clinical significance
The relationship between periodontium and systemic factors is bidirectional and interlinked. Therefore, dentists and physicians should take this into account while treating patients, aiming for the overall betterment of the patient.

ABSTRACT

Aim
The aim of this study was to establish the validity of a new method for evaluating skeletal maturation by assessing the 3rd and 4th cervical vertebrae seen in the cephalometric radiograph.

Materials and methods
This study consisted of a sample of 50 patients in the age group of 8 to 14 years of age. Chronologically, they were divided into six groups, based on the age consisting of a minimum of six to a maximum of 10 subjects. All the patients included in the study were females. The selected subjects were clinically examined and then age and date of birth of the patient in years and months was noted. Then lateral cephalograms and hand-wrist radiographs of the patient were taken on the same day with good clarity and contrast.

Results
The results suggested that cervical vertebral bone age on cephalometric radiographs calculated with this method is as reliable at estimating bone age as is the Tanner-Whitehouse 3 (TW3) method on hand-wrist radiographs. By determining the cervical vertebral bone age, skeletal maturity can be evaluated in a detailed and objective manner with cephalometric radiographs.

Conclusion
The ability to accurately appraise skeletal maturity from cervical vertebral maturation, without the need for additional radiographs, has the potential to improve orthodontic diagnostic and therapeutic decisions. The technique's simplicity and ease of use should encourage this method as a first level diagnostic tool to assess skeletal maturation.

Clinical significance
This study revealed that the timing and sequence of ossification of the bones in hand and wrist and cervical vertebrae were able to relate the skeletal development of the various skeletal maturity indicators to a child's development. This method provided a mean with which one can determine the skeletal maturity of a person and thereby determine whether the possibility of potential growth existed.
