Sacred Music, Sacred Journeys : What Makes an Event Postcolonial ?
Authors: Salzbrunn Monika , Weichs Raphaela von 
Published: November 2013

Fanon, Senghor, and Ela took a radical stance in criticising the structures and mechanisms of power in hegemonic situations and relations between colonial subjects and colonial masters. They aimed to liberate African societies by decolonising the mind, culture and religion of colonial subjects. In this respect, we are concerned with the continuities and ruptures of the colonial encounter and its unequal relationships. Switzerland does not have an official colonial history and yet, Swiss companies and migrants were and are part of the world’s colonies. In our contribution, we question what makes an event postcolonial : in other words, how are postcolonial relations negotiated in Switzerland?We discuss this question by analysing two annual sacred journeys in Switzerland that have been invented for and by African Christians (clerics and laity) together with the leaders of the Swiss Catholic church : one to the relics of African saints in St. Maurice, canton Valais and the other to the Black Madonna, the Virgin Mary of Einsiedeln, in the canton Schwyz. These events are empowered by the performance of African choirs – their music, dance, and costumes – but to which end and in which way?
Slit2–Robo4 Pathway Modulates Lipopolysaccharide-Induced Endothelial Inflammation and Its Expression Is Dysregulated during Endotoxemia

Published: November 2013

Abstract
The secretory protein Slit2 and its receptors Robo1 and Robo4 are considered to regulate mobility and permeability of endothelial cells and other cell types. However, the roles of Slit2 and its two receptors in endothelial inflammatory responses remain to be clarified. In this study, we show that, in primary HUVECs, Slit2 represses LPS-induced secretion of certain inflammatory cytokines/chemokines, cell adhesion molecule ICAM-1 upregulation, and monocyte adhesion. Slit2’s anti-inflammatory effect is mediated by its dominant endothelial-specific receptor Robo4. However, the minor receptor Robo1 has proinflammatory properties and is downregulated by Slit2 via targeting of miR-218. Elucidation of molecular mechanism reveals that Slit2 represses inflammatory responses by inhibiting the Pyk2–NF-κB pathway downstream of LPS–TLR4. Further studies reveal that LPS enhances endothelial inflammation by downregulating the anti-inflammatory Slit2 and Robo4 in HUVECs in vitro, as well as in arterial endothelial cells and liver in vivo during endotoxemia. These results suggest that Slit2–Robo4 signaling is important in regulating LPS-induced endothelial inflammation, and LPS, in turn, enhances inflammation by interfering with the expression of the anti-inflammatory Slit2–Robo4 during the disease state. This implies that Slit2–Robo4 is a key regulator of endothelial inflammation, and its dysregulation during endotoxemia is a novel mechanism for LPS-induced vascular pathogenesis.
Gene Expression Meta-Analysis identifies Cytokine Pathways and 5q Aberrations involved in Metastasis of ERBB2 Amplified and Basal Breast Cancer

Published: November 2013

Background Breast tumors have been described by molecular subtypes characterized by pervasively different gene expression profiles. The subtypes are associated with different clinical parameters and origin of precursor cells. However, the biological pathways and chromosomal aberrations that differ between the subgroups are less well characterized. The molecular subtypes are associated with different risk of metastatic recurrence of the disease. Nevertheless, the performance of these overall patterns to predict outcome is far from optimal, suggesting that biological mechanisms that extend beyond the subgroups impact metastasis. Results We have scrutinized publicly available gene expression datasets and identified molecular subtypes in 1,394 breast tumors with outcome data. By analysis of chromosomal regions and pathways using “Gene set enrichment analysis” followed by a meta-analysis, we identified comprehensive mechanistic differences between the subgroups. Furthermore, the same approach was used to investigate mechanisms related to metastasis within the subgroups. A striking finding is that the molecular subtypes account for the majority of biological mechanisms associated with metastasis. However, some mechanisms, aside from the subtypes, were identified in a training set of 1,239 tumors and confirmed by survival analysis in two independent validation datasets from the same type of platform and consisting of very comparable node-negative patients that did not receive adjuvant medical therapy. The results show that high expression of 5q14 genes and low levels of TNFR2 pathway genes were associated with poor survival in basal-like cancers. Furthermore, low expression of 5q33 genes and interleukin-12 pathway genes were associated with poor outcome exclusively in ERBB2-like tumors. Conclusion The identified regions, genes, and pathways may be potential drug targets in future individualized treatment strategies.
Self-Reported Therapeutic Style in Occupational Therapy Students
Authors: Bonsaksen Tore 
Published: November 2013

Introduction: The client-therapist relationship has long been viewed as important for both the process and outcomes of occupational therapy. The recently developed Intentional Relationship Model introduced six therapeutic modes as different ways of relating to clients. Increasing students' awareness of modes, and increasing their skills in using them flexibly, has the potential of improving their subsequent practice as occupational therapists. This article aims to describe occupational therapy students' affiliation with the therapeutic modes in a variety of hypothesized practice situations. In addition, relationships between the students' affiliation with the different modes are explored. Method: The study had a cross-sectional design. Data were collected from 31 occupational therapy students in Norway, using the Self-Assessment of Modes Questionnaire. Descriptive analyses, repeated measures ANOVA tests, and correlation analyses were employed in the analytic procedures. Findings: The students identified the problem-solving mode to be their most preferred way of relating to clients, whereas the advocating mode was the least preferred. High affiliation with the problem-solving mode was significantly associated with low affiliation with the collaborating mode. Conclusion: Several limitations indicate that caution should be taken when comparing this study with previous research. Nonetheless, differences between the results of this study and previous work on the therapeutic modes are of interest. Possible explanations for differences are discussed, as are implications for practice and research.
Individual and Environmental Implications of Working Alliances in Occupational Therapy
Authors: Morrison Tricia 
Published: November 2013

Introduction: The therapeutic alliance is constituted of two predominant actors, the client and therapist, and is embedded within a rich environment that may both facilitate and restrict the alliance development. Method: A mixed-methods, prospective, multiple case study approach was used to compare the contextual characteristics and experiences of the working alliance over the course of a community-based occupational therapy intervention by four dyads, each composed of an occupational therapist and client. Findings: The findings of this study suggest that there are a variety of therapist, client, and environmental factors that interact with one another, each having a different impact on the process of alliance development. Conclusion: Although therapists must shoulder the responsibility of creating a therapeutic atmosphere conducive to sound working alliance development, there are also elements having an impact on the alliance that are outside the therapist's control. Although these findings point to development potentials for therapists to consider, related to the therapeutic use-of-self, there is also a need for vigilance in relation to career health in assuming responsibility for elements that therapists cannot always mediate.

Published: November 2013

ABSTRACT

Aim
To identify the current materials, design, communication and disinfection status followed by the dental laboratories in India regarding fixed prosthodontics.

Materials and methods
A prepiloted anonymous questionnaire containing 27 questions related to fixed prosthodontics was send to 472 laboratories in India. Information was obtained regarding procedure and materials for fixed prosthesis, die technique, accuracy of casts, design, communication, shade selection and disinfection practices followed by the laboratories. Questionnaire data were entered into a computer and analyzed using SPSS version 12.0 (SPSS, Inc, Chicago, IL, USA).

Results
Two hundred and sixteen of 472 dental laboratories responded (45.76% response rate). Most common pontic design in both arches was ridge lap. One hundred and fifty-four (71.29%) laboratories presented that most of the casts were not articulated. Majority of impression (66.20%) received are not accurate enough for laboratories to do their best work. One hundred and eighty (82.8%) laboratories have stated that less than 25% casts were disinfected. Most of the dentists (65.74%) were not sending work authorization form and those who were sending are not complete enough (63.42%).

Conclusion
The finding in this study indicated the weakness in technique and design of fixed prosthesis along with poor communication between dentists and laboratories in India.

Evaluation of Fracture Resistance of Reattached Vertical Fragments Bonded with Fiber-reinforced Composites: An in vitro Study
Authors: Gopal S Sujatha , Kumar B Shiva , Spoorti P , Reddy Jeetender , Ittigi Jayaprakash 
Published: November 2013

ABSTRACT

Aim
Aim of this in vitro study was to evaluate the resistance to fracture of vertically fractured and reattached fragments bonded with fiber-reinforced composites.

Materials and methods
Root canals of 45 teeth were prepared, and the teeth were intentionally fractured into two separate fragments. Control groups (n = 15 each) consisted unfractured teeth with instrumented and obturated. Fractured teeth were divided into three groups (n = 15) and were attached using (1) dual-cure resin cement (RelyX U100), (2) dual-cure resin cement and polyethylene fiber (Ribbond), (3) dual-cure resin cement and glass fibers (stick-net). Force was applied at a speed of 0.5 mm/min to the root until fracture.

Results and statistical analysis
Group 1 (RelyX U100 group) demonstrated lowest fracture resistance. Group 4 (control group) showed highest fracture resistance followed by group 2 (Ribbond group) and group 3 (Stick-Net groups). Statistically no significant difference was there between groups 2, 3 and 4.

Conclusion
Vertically fractured teeth can be treated by filling the root canal space with dual-cure adhesive resin cement or by adding polyethylene fiber or glass fiber to increase the fracture resistance of the reattached tooth fragments, an alternative to extraction.

Periodontal Pathogens and Respiratory Diseases— Evaluating Their Potential Association: A Clinical and Microbiological Study
Authors: Nayak Rashmita , Spoorthi BR , Vadiraj S , Choudhary Gopal Krishna , Kudyar Nitin 
Published: November 2013

ABSTRACT

Objective
To evaluate whether any potential association exists between respiratory diseases such as chronic obstructive pulmonary disease (COPD) and periodontal health status clinically and or microbiologically.

Materials and methods
Fifty patients of COPD (test group) and 50 Patients without COPD (control group) were recruited for the study with more than 20 years of age with at least six natural teeth. All the patients were nonsmokers. Periodontal health was assessed by measuring clinical attachment loss (CAL) and gingival bleeding by using William's graduated periodontal probe. Microbiological evaluation was done by collecting sputum samples of the subjects with respiratory diseases to find out any periodontal pathogen in the lung fluid.

Result and conclusion
The results showed that the subjects with COPD had significantly more bleeding sites (i.e. >20%) and had more of the clinical mean attachment loss (2.84 ± 0.66) than those without COPD. On the basis of the observed results of the study, we can hypothesize that the risk for COPD appeared to be significantly elevated when attachment loss was found to be severe.

Clinical significance
It is conceivable that oral interventions that improve oral health status may prove to lower the severity of lung infection in susceptible populations.

Bond Strength of Overdenture Locator Posts Cemented with Seven Luting Agents
Authors: Aleisa Khalil 
Published: November 2013

ABSTRACT

Statement of the problem
Post retention is crucial factor in restoration survival. Posts are commonly failed due to loss of retention. It is unknown which luting agents would provide the maximum bond strength for Locator overdenture posts.

Aim
The aim of this study was to evaluate the bond retentive strengths of Locator overdenture posts cemented with 7 luting agents.

Materials and methods
One hundred and five single rooted human teeth were decoronated and randomly assigned to 7 groups (n = 15). Post spaces were prepared with Locator post drills to the depth of 6 mm. The Locator posts were cemented with Variolink II, RelyX ARC, Multilink N, RelyX Unicem, ParaCore, or MultiCore Flow resin luting agents. Zinc phosphate cement was served as control group. Specimens were stored in water at 37°C for 24 hours. Each specimen was loaded in tension in an Instron universal testing machine. The maximum force required to dislodge each Locator post was recorded. Means and standard deviations were calculated and data were statistically analyzed with one-way analysis of variance (ANOVA).

Results
The highest mean bond strength value for Locator posts was recorded for MultiCore® Flow group (mean = 550.1 N), while the lowest mean value was for RelyX Unicem™ resin cement group (mean = 216.8 N). A statistically significant difference in mean locator overdenture post bond strength was observed between the 7 cement types (p < 0.0001). ParaCore™ and MultiCore® Flow groups had significantly higher bond strength than all other groups, but they were not differed from each other.

Conclusion
Bond strength of Locator overdenture posts were influenced by the type of luting agents. MultiCore Flow and ParaCore resin cements offered the greatest retention.

Clinical significance
The type of luting agents had a significant effect on the retention of Locator posts. The use of Core buildup resin cements as luting agent with Locator post demonstrated the greatest retention.

Authors: Al-Samadani Khalid H 
Published: November 2013

ABSTRACT

Objective
To evaluate the effect of Arabic coffee, Turkish coffee and Nescafe on the color stability of four different composite resins after a period of aging time 1, 7 and 30 days.

Materials and methods
Twenty specimens from each type of tested composite resin material were prepared. Five specimens from each tested material (Z350 XT, Artist, GC and Z250) was evaluated after storage in Arabic coffee, Turkish coffee, Nescafe and distil water (control) at 37°C in a dark container for 1, 7 and 30 days. Color measurement was done using colorimeter based on the CIE L* a* b* color scale. Color differences ΔE*ab, Δb* and Δa* among specimens immersed in distil water and staining coffee beverages were evaluated overtime. Mean values were statistically analyzed with one-way analysis of variance (ANOVA), followed by Tukey test with p < 0.05 as significance level.

Results
All tested composite resins showed increase color change after a period of 1, 7 and 30 days. The color change ΔE*ab, Δb* and Δa* exhibited by Arabic coffee, in Turkish coffee and Nescafe except Δa*. The highest total color difference ΔE*ab after 30 days was in group A Arabic coffee (ΔE > 1.5 perceivable) and not perceivable in group B Turkish coffee and group C Nescafe. For Δb* all materials discolored toward yellowness after 30 days except Arabic coffee group which shifted from yellowness toward blueness (Δb*> 1.5 perceivable).

Conclusion
The effect of staining beverages on the resin composite materials increases with time of aging toward yellowness and not perceivable in all groups except with Arabic coffee which had highest effect after 30 days and the discoloration shifted from yellowness to blueness perceivable.
