The peripheral perfusion index and transcutaneous oxygen challenge test are predictive of mortality in septic patients after resuscitation
Authors: He Huai-wu , Liu Da-wei , Long Yun , Wang Xiao-ting 
Published: June 2013

Abstract
Introduction
The peripheral perfusion index (PI) is a noninvasive numerical value of peripheral perfusion, and the transcutaneous oxygen challenge test (OCT) is defined as the degree of transcutaneous partial pressure of oxygen (PtcO2) response to 1.0 FiO2. The value of noninvasive monitoring peripheral perfusion to predict outcome remains to be established in septic patients after resuscitation. Moreover, the prognostic value of PI has not been investigated in septic patients.

Methods
Forty-six septic patients, who were receiving PiCCO-Plus cardiac output monitoring, were included in the study group. Twenty stable postoperative patients were studied as a control group. All the patients inspired 1.0 of FiO2 for 10 minutes during the OCT. Global hemodynamic variables, traditional metabolic variables, PI and OCT related-variables were measured simultaneously at 24 hours after PiCCO catheter insertion. We obtained the 10min-OCT ((PtcO2 after 10 minutes on inspired 1.0 oxygen) - (baseline PtcO2)), and the oxygen challenge index ((10min-OCT)/(PaO2 on inspired 1.0 oxygen - baseline PaO2)) during the OCT.

Results
The PI was significantly correlated with baseline PtcO2, 10min-OCT and oxygen challenge index (OCI) in all the patients. The control group had a higher baseline PtcO2, 10min-OCT and PI than the septic shock group. In the sepsis group, the macro hemodynamic parameters and ScvO2 showed no differences between survivors and nonsurvivors. The nonsurvivors had a significantly lower PI, 10min-OCT and OCI, and higher arterial lactate level. The PI, 10min-OCT and OCI predicted the ICU mortality with an accuracy that was similar to arterial lactate level. A PI <0.2 and a 10min-OCT <66mmHg were related to poor outcome after resuscitation.

Conclusions
The PI and OCT are predictive of mortality for septic patients after resuscitation. Further investigations are required to determine whether the correction of an impaired level of peripheral perfusion may improve the outcome of septic shock patients.

Abstract
Introduction
Glucagon-like peptide-1 (GLP-1) originates from the gastrointestinal system in response to the presence of nutrition in the intestinal lumen and potentiates postprandial insulin secretion. Also, it acts as an immune-modulator which has influences on cell-mediated immunity.
The aim of this study was to determine the impact of early enteral nutrition versus late enteral nutrition on plasma GLP-1 levels and the relationship between GLP-1 changes and cell-mediated immunity.

Materials and methods
The study was designed as a prospective, single-blinded study and carried out in the neurology intensive care unit (ICU) of a university hospital. Twenty-four naive patients with acute thromboembolic cerebrovascular events, with National Institute of Health (NIH) stroke scores between 12 and 16, were included. Any condition interfering with GLP-1 and immunity was regarded as exclusion criterion. Two patients died, and two dropped out of the study due to complicating conditions.
Patients were randomly subjected to early enteral feeding within the first 24 hours (Group 1), or late enteral feeding, beginning 48 hours after admission (Group 2) via a nasogastric tube. Calculated daily energy requirement was supplemented with parenteral nutrition, starting on the first study day for both groups. Blood samples were obtained before, and at 5, 15, 30, 60 and 120 minutes after the first enteral feeding for GLP-1 assays; this procedure was repeated on the third day. Before and 24 hours after the first enteral feeding, samples were also taken for immunological analysis. Clinical observations were recorded.
Pre- and post-feeding plasma GLP-1 changes between the two groups and within groups were evaluated. Lymphocyte subgroup changes before and 24 hours after the first enteral feeding in relation to GLP-1 changes were sought as well.

Results
Group 1 and Group 2 exhibited similar GLP-1 levels in the pre-feeding and post-feeding periods for both the first time and the third day of enteral feeding. Also, no significant change in pre-/post-feeding GLP-1 levels was observed within groups. T-helper and T-regulatory cells increased, T-cytotoxic cells decreased significantly in Group 1 (P = 0.02; P = 0.036; P = 0.0019), but remained the same in Group 2 after enteral feeding. Positive but statistically insignificant clinical effects in terms of predisposition to infections (10% vs 40%) and median time of ICU stay (10 vs 15 days) were observed in Group 1.

Conclusions
Depending on our findings, we propose that early enteral feeding may cause amelioration in cell-mediated immunity via factors other than GLP-1 in ICU patients with acute thromboembolic stroke. However, the possible deleterious effects of parenteral nutrition cannot be ruled out.
Designing writing/designing reading: Textual ontologies and poetic practice
Authors: Hall Sean 
Published: June 2013

Abstract
Standardized writing and reading practices in academia are well established. The academic book, article, dissertation and the report are all familiar in terms of both form and content. But due to the various forms of standardization it is often hard to challenge the Mandarin diseases of ‘group’ thought and instruction that Universities breed in imposing their own strict writing and reading protocols and forms of pedagogy. (Alongside these things sit all the evaluative forms and kinds of assessment machinery that go with the practice of trying to count and measure everything that academics or students produce.) So if we need to consider new ways to design writing and reading we should think more about the way in which we actually live with text, both virtually and actually. In order to present new semantic challenges for new writers and readers, then, we need might need to look at the ways that other practitioners from different fields and disciplines use and create (and curate) writing and reading – where ‘con’ (with) combines with ‘textere’ (weave/text) so that the text is woven with new meanings. In what follows, then, I will consider how a poetics of textual practice may start to encourage students to engage with richer, and more carefully designed, forms of meaning. More specifically, I wish to draw on various tasks that can be set to encourage student designers to put more meaning into their writing by making challenges to form. The production of writing and reading can be considered as integral to the research and ideational processes of design work. And so how graphic design can engender, unfold and fuse with other creative practices such as poetry may be important in enabling new textual rhythms, harmonies and melodies to develop in the subject of design.
Critical thinking as an embodied criticality: The lived experiences of international art students
Authors: Riley-Jones Gary 
Published: June 2013

Abstract
Using an adapted narrative enquiry approach, the purpose of the research is to present a model of criticality based on R. Barnett’s argument that criticality should ‘create epistemological and ontological disturbance in the minds and in the being of students’, which Barnett argues is a prerequisite to critical being, or in I. Rogoff’s terms, a ‘critical embodiment’. Inevitably, such a conceptualization involves a reformation of the student’s subject position including their sense of identity and it is clear that despite the ‘messy’ data provided by these unstructured narrative interviews with two international fine art students, there is evidence for Barnett’s and Rogoff’s positions. Indeed, identity is central to the practice of both participants who articulate their sense of othering in Foucauldian terms, operating at a very cognitive level within a western regime of truth.
Repeat orienteering
Authors: Upton Lawrence 
Published: June 2013

Abstract
An intermedia approach to writing is proposed in which the writing processes are seen as forms of inscription of media enabling the writer to learn from and adapt techniques from, for example, music and graphic art. Collaboration is proposed as a productive way of extending and expanding the writer’s skills. The centrality of writing as a means of instruction is questioned to propose the potential meaningfulness of even the asemic collocation.
Technological augmented narratives in public transportation
Authors: Ashkenazi Avi 
Published: June 2013

Abstract
This article stems from a brief about narrative and technology assigned during my M.A. Design Critical Practice at Goldsmiths, University of London. The project that developed from the brief was a group project, so when I say ‘we’ I mean my group: Blair Francy, Marion Lean and Jullian Lee. Our goal was to find new ways of telling narratives. These ways should carry in them the ability to create a better experience of story: engaging, revolving and natural. This article suggests new design concepts for the transportation system derived from a combination of creative writing methods, technology development processes, acting techniques (bodystorming) and design methodology.
The camera and the collecting gene
Authors: Rozental Rotem 
Published: June 2013

Abstract
The merging of the positions of photographer and collector defines the drive of a certain kind of photographic work, for which the camera becomes a collecting device, accumulating a collection that speaks the subjectivity of its author – the photographer. There are, however, two impulses at work here: the photographer-as-collector and the collector-as-photographer. Both are present in the work of Martin Parr, who has openly admitted that he has ‘the collecting gene’, but also, somewhat earlier, in the work of Walker Evans whose obsession with collectibles and whose mode of photographic collecting provide a striking historical precedent for Parr’s compulsive practice. My article explores the collecting impulse that motivates these photographers and, more particularly, shapes a new mode of making photographs and cataloguing social life that seem to escape established genre categories, including especially the category of documentary.

Messunsicherheit primärer Auswahlsysteme zur Schwingungskalibrierung
Authors: Bühn Uwe , Begoff Philipp , Nicklich Holger 
Published: June 2013

Zusammenfassung
Primärsysteme zur Schwingungskalibrierung sind gekennzeichnet durch eine interferometrische Messung der Schwingungsgröße. In der Standard-Ausführung haben sie bereits eine recht geringe Messunsicherheit. Definiert man ein so genanntes Auswahlsystem mit fester Zuordnung aller Komponenten und ermittelt dafür die dominierenden Einflussfaktoren, dann erzielt man noch geringere Messunsicherheiten. Ist ein Auswahlsystem für den Einsatz in einem NMI vorgesehen, so entfällt die Rückführung auf das nationale Normal, und es werden Bestwerte für die Messunsicherheit erzielt.
Impact of bovine leukemia virus infection on neutrophil and lymphocyte concentrations in dairy cattle
Authors: Swenson Cheryl L. , Erskine Ronald J. , Bartlett Paul C. 
Published: June 2013

Abstract
Objective—To determine the effect of bovine leukemia virus (BLV) infection on absolute neutrophil and lymphocyte concentrations in healthy lactating Holstein dairy cattle.
Design—Observational cross-sectional survey.
Animals—311 healthy lactating Holstein dairy cattle from herds in Michigan (n = 2), Wisconsin (1), Iowa (1), and Pennsylvania (1).
Procedures—Whole and anticoagulated (EDTA) blood samples were collected. Serum samples were tested for antibody against BLV by use of an ELISA. Absolute neutrophil and lymphocyte concentrations were measured in EDTA blood samples with an automated hematology analyzer and manual differential cell counts.
Results—208 cows tested positive and 103 cows tested negative for anti-BLV antibodies. Neutrophil concentration was not significantly different between BLV-positive versus BLV-negative cattle. The distribution of lymphocyte concentration was positively skewed for the entire cow population (n = 311) and the BLV-positive subset (208). In contrast, lymphocyte concentration distribution was approximately normal for BLV-negative cows (n = 103). Consequently, the presence or absence of BLV infection strongly influenced the calculated neutrophil-to-lymphocyte concentration ratio.
Conclusions and Clinical Relevance—Results indicated that absolute lymphocyte concentration is significantly affected by BLV infection in dairy cattle. Accordingly, hematologic reference intervals should be derived from healthy animals that are not infected with BLV and patient BLV status must be considered for meaningful interpretation of lymphocyte concentration. We recommend that the calculated neutrophil-to-lymphocyte ratio be abandoned because it does not provide more information than direct comparison of patient absolute leukocyte concentration with updated reference intervals from healthy BLV-negative cattle.
Configurations d'activité collective et processus d'apprentissage lors de travaux pratiques
Authors: Guérin Jérôme 
Published: June 2013

Cet article est consacré à l’étude de l’activité collective lors de travaux pratiques en lycée professionnel. En s’inscrivant dans une approche orientée « activité », l’objectif de l’étude est de décrire les formes d’interactions entre les élèves et l’enseignant en classe afin d’identifier leurs incidences sur le maintien d’une activité collective viable et les processus d’apprentissage. La reconstruction de l’organisation et de la signification de l’activité a mis en évidence des formes typiques de configuration d’activité collective qui participent à l’investissement durable des élèves et offrent des opportunités en termes d’apprentissage. Une analyse fine d’un cas exemplaire de processus de coordinations et d’ajustements montre comment les enseignants exploitent l’émergence des erreurs de production pour inciter les élèves à construire de nouvelles connaissances pour l’action et à étendre la signification de savoirs théoriques. L’article discute la relation entre configuration d’activité et culture commune, la relation entre activité productive et activité constructive, et la spécificité de la disposition des enseignants à enseigner en travaux pratiques.
Politique monétaire unique, taux bancaires et prix immobiliers dans la zone euro
Authors: Blot Christophe , Labondance Fabien 
Published: June 2013

L’objectif de notre contribution est d’analyser empiriquement les mécanismes de transmission de la politique monétaire vers les prix immobiliers dans les principales économies de la zone euro. Nous tenons compte explicitement du rôle des banques, via le canal du taux d’intérêt. Notre approche est en deux étapes : la première permet d’illustrer la répercussion des taux contrôlés par la BCE sur les taux pratiqués par les banques pour les crédits immobiliers, tandis que la deuxième fait le lien entre les taux bancaires et les prix immobiliers. Cette analyse permet de comprendre les différentes sources de l’hétérogénéité de la transmission de la politique monétaire. Il apparaît en effet que le canal du taux d’intérêt est de plus en plus homogène dans la zone euro. Mais ce résultat masque le rôle des effets d’offre de crédit qui ont pu induire une hétérogénéité de la transmission de la politique monétaire. La transmission des taux bancaires aux prix immobiliers et à l’ensemble de l’économie demeure dépendante des structures propres à chaque État membre.
Psychose, somatose... et entre les deux
Authors: Chambrier-Slama Josiane 
Published: June 2013

L’auteur rappelle la place que Michel de M’Uzan accorde aux fonctionnements paradoxaux et lui pose cinq questions. Existe-t-il en clinique un seul type de désinvestissement ? Ne faut-il pas considérer de nouveaux types de narcissismes ? Peut-on se contenter d’écarter la référence à la pulsion de mort et se proposer, là où la destructivité fait rage, « d’être nulle part » ? Cette référence, insistante en clinique contemporaine, ne témoigne-t-elle pas d’un moment évolutif du processus théorisant, à dépasser ? Quels rapports entre somatose et état-limite ?

Published: June 2013

ABSTRACT

Introduction
Base metals have a wide use in casting methods. Sometimes they are reused in laboratories which may have an adverse effect on the restoration marginal integrity. This study aimed to investigate the effect of recasting of alloys on marginal integrity of restorations.

Materials and methods
Models with two types of finishing lines shoulder bevel 45° and shoulder 135° were produced and 15 wax copings were formed on each one of them. Each group containing 15 copings was divided into three subgroups A, B and C. Group A was casted with 100% new alloy, group B with 50% new and 50% recasted alloy and group C with 100% recasted alloy. Obtained metal copings were placed on dies and marginal gap size between restoration margin and the dies finishing line was measured using metric microscope and Moticam camera in four points, buccal, lingual, mesial and distal.

Results
A significant difference in mean marginal gap size exists among three types of alloys used (p-value = 0.036). A significant difference is observed between mean marginal gap size of two types of finishing lines for different alloys (p-value = 0.001).

Conclusion
Using 100% recasted alloy is not recommended for any of the two types of finishing lines.

Nature and magnitude of aromatic base stacking in DNA and RNA: Quantum chemistry, molecular mechanics, and experiment

Published: June 2013

ABSTRACTBase stacking is a major interaction shaping up and stabilizing nucleic acids. During the last decades, base stacking has been extensively studied by experimental and theoretical methods. Advanced quantum‐chemical calculations clarified that base stacking is a common interaction, which in the first approximation can be described as combination of the three most basic contributions to molecular interactions, namely, electrostatic interaction, London dispersion attraction and short‐range repulsion. There is not any specific π–π energy term associated with the delocalized π electrons of the aromatic rings that cannot be described by the mentioned contributions. The base stacking can be rather reasonably approximated by simple molecular simulation methods based on well‐calibrated common force fields although the force fields do not include nonadditivity of stacking, anisotropy of dispersion interactions, and some other effects. However, description of stacking association in condensed phase and understanding of the stacking role in biomolecules remain a difficult problem, as the net base stacking forces always act in a complex and context‐specific environment. Moreover, the stacking forces are balanced with many other energy contributions. Differences in definition of stacking in experimental and theoretical studies are explained. © 2013 Wiley Periodicals, Inc. Biopolymers 99: 978–988, 2013.
Characterizing Carbohydrate–Protein Interactions by Nuclear Magnetic Resonance Spectroscopy
Authors: Bewley Carole A. , Shahzad‐ul‐Hussan Syed 
Published: June 2013

ABSTRACTInteractions between proteins and soluble carbohydrates and/or surface displayed glycans are central to countless recognition, attachment and signaling events in biology. The physical chemical features associated with these binding events vary considerably, depending on the biological system of interest. For example, carbohydrate–protein interactions can be stoichiometric or multivalent, the protein receptors can be monomeric or oligomeric, and the specificity of recognition can be highly stringent or rather promiscuous. Equilibrium dissociation constants for carbohydrate binding are known to vary from micromolar to millimolar, with weak interactions being far more prevalent; and individual carbohydrate‐binding sites can be truly symmetrical or merely homologous, and hence, the affinities of individual sites within a single protein can vary, as can the order of binding. Several factors, including the weak affinities with which glycans bind their protein receptors, the dynamic nature of the glycans themselves, and the nonequivalent interactions among oligomeric carbohydrate receptors, have made nuclear magnetic resonance (NMR) an especially powerful tool for studying and defining carbohydrate–protein interactions. Here, we describe those NMR approaches that have proven to be the most robust in characterizing these systems, and explain what type of information can (or cannot) be obtained from each. Our goal is to provide the reader the information necessary for selecting the correct experiment or sets of experiments to characterize their carbohydrate–protein interaction of interest.

Mechanism of Palladium‐Catalyzed Suzuki–Miyaura Reactions: Multiple and Antagonistic Roles of Anionic “Bases” and Their Countercations
Authors: Amatore Christian , Le Duc Gaëtan , Jutand Anny 
Published: June 2013

AbstractIn Suzuki–Miyaura reactions, anionic bases F− and OH− (used as is or generated from CO32− in water) play multiple antagonistic roles. Two are positive: 1) formation of trans‐[Pd(Ar)F(L)2] or trans‐[Pd(Ar)‐ (L)2(OH)] (L=PPh3) that react with Ar′B(OH)2 in the rate‐determining step (rds) transmetallation and 2) catalysis of the reductive elimination from intermediate trans‐[Pd(Ar)(Ar′)(L)2]. Two roles are negative: 1) formation of unreactive arylborates (or fluoroborates) and 2) complexation of the OH group of [Pd(Ar)(L)2(OH)] by the countercation of the base (Na+, Cs+, K+).
