Abstract

Background
Recently, postnatal stem cells from dental papilla with neural crest origin have been considered as one of potent stem cell sources in regenerative medicine regarding their multi-differentiation capacity and relatively easy access. However, almost human oral tissues have been reported to be infected by mycoplasma which gives rise to oral cavity in teeth, and mycoplasma contamination of ex-vivo cultured stem cells from such dental tissues and its effect on stem cell culture has received little attention.

Results
In this study, mycoplama contamination was evaluated with stem cells from apical papilla which were isolated from human third molar and premolars from various aged patients undergoing orthodontic therapy. The ex-vivo expanded stem cells from apical papilla were found to express stem cell markers such as Stro-1, CD44, nestin and CD133, but mycoplama contamination was detected in almost all cell cultures of the tested 20 samples, which was confirmed by mycoplasma-specific gene expression and fluorescence staining. Such contaminated mycoplasma could be successfully eliminated using elimination kit, and proliferation test showed decreased proliferation activity in mycoplasma-contaminated cells. After elimination of contaminated mycoplasma, stem cells from apical papilla showed osteogenic and neural lineage differentiation under certain culture conditions.

Conclusion
Our study proposes that the evaluation of mycoplasma contamination and elimination process might be required in the use of stem cells from apical papilla for their potent applications to tissue engineering and regenerative medicine.
Insect navigation: do ants live in the now?
Authors: Graham Paul , Mangan Michael 
Published: March 2015

ABSTRACT
Visual navigation is a critical behaviour for many animals, and it has been particularly well studied in ants. Decades of ant navigation research have uncovered many ways in which efficient navigation can be implemented in small brains. For example, ants show us how visual information can drive navigation via procedural rather than map-like instructions. Two recent behavioural observations highlight interesting adaptive ways in which ants implement visual guidance. Firstly, it has been shown that the systematic nest searches of ants can be biased by recent experience of familiar scenes. Secondly, ants have been observed to show temporary periods of confusion when asked to repeat a route segment, even if that route segment is very familiar. Taken together, these results indicate that the navigational decisions of ants take into account their recent experiences as well as the currently perceived environment.
Six degree-of-freedom analysis of hip, knee, ankle and foot provides updated understanding of biomechanical work during human walking
Authors: Zelik Karl E. , Takahashi Kota Z. , Sawicki Gregory S. 
Published: March 2015

ABSTRACT
Measuring biomechanical work performed by humans and other animals is critical for understanding muscle–tendon function, joint-specific contributions and energy-saving mechanisms during locomotion. Inverse dynamics is often employed to estimate joint-level contributions, and deformable body estimates can be used to study work performed by the foot. We recently discovered that these commonly used experimental estimates fail to explain whole-body energy changes observed during human walking. By re-analyzing previously published data, we found that about 25% (8 J) of total positive energy changes of/about the body's center-of-mass and &gt;30% of the energy changes during the Push-off phase of walking were not explained by conventional joint- and segment-level work estimates, exposing a gap in our fundamental understanding of work production during gait. Here, we present a novel Energy-Accounting analysis that integrates various empirical measures of work and energy to elucidate the source of unexplained biomechanical work. We discovered that by extending conventional 3 degree-of-freedom (DOF) inverse dynamics (estimating rotational work about joints) to 6DOF (rotational and translational) analysis of the hip, knee, ankle and foot, we could fully explain the missing positive work. This revealed that Push-off work performed about the hip may be &gt;50% greater than conventionally estimated (9.3 versus 6.0 J, P=0.0002, at 1.4 m s−1). Our findings demonstrate that 6DOF analysis (of hip–knee–ankle–foot) better captures energy changes of the body than more conventional 3DOF estimates. These findings refine our fundamental understanding of how work is distributed within the body, which has implications for assistive technology, biomechanical simulations and potentially clinical treatment.

The luteinizing hormone/choriogonadotropin (LH/CG) receptor plays an important role in male and female infertility. Many studies have demonstrated that mutations at specific sites in LHCGR gene may result in mild or complete loss of receptor function. Insertions in exon-1 of LHCGR gene were first studied in male Leydig cell hypoplasia and later extended to female reproductive disorders. Previous studies have shown that these insertions play an important role in intrauterine insemination (IUI) and in vitro fertilization (IVF) outcome. Here we report a 54bp insertion in a 28-year old woman with infertility, recurrent cyst formation and failed stimulated IUI cycles. As the patient showed a blunted response to the ovarian stimulation and human chorionic gonadotropin (hCG) stimulation test, follicle stimulating hormone receptor (FSHR) and luteinizing hormone/choriogonadotropin (LHCGR) gene sequencing was performed. Gene sequence analysis revealed a 54bp homozygous insertion (GCTGCTGAAGCTGCTGCTGCTGCTGCAGCTGCTGAAGCTGCTGCTGCTGCTGCA) in the exon-1 of LHCGR gene. This mutation might have caused a decrease in receptor function in the present infertile patient, thus resulting in poor ovarian response.
Contact improvisation as an art of relating: The importance of touch for building positive interaction
Authors: Jussilainen Anna 
Published: March 2015

Abstract
This article analyses the specific characteristics of Contact Improvisation (CI) that can support building positive interaction and well-being in community contexts. It examines the possibilities of the dance form to widen attitudes towards touch and to build skills in touching and communication, also with people experiencing difficulties with touch. CI practice proposes a different way of being and relating to people, challenging normative behaviour and creating communal feelings by emphasizing togetherness and connectedness. It can have many positive effects, including enhancing awareness and encouraging playfulness and mutual support, as well as increasing the joy of life, as demonstrated in my study with professionals and women in vulnerable positions. The article also suggests that, although the potential for negatively experienced touch needs attention in CI practice and in society at large, building skills and awareness in qualities of how to touch can reduce such experiences. In terms of currently acceptable modes of touching in contemporary culture, touching in particular ways can also be seen as political, suggesting a strong potential influence of dancing on everyday life.
Movement in the Men’s Movement: Contact improvisation and social change
Authors: Curtis Jess 
Published: March 2015

Abstract
During the 1970s and continuing through to the 1990s, a significant number of American men participated in activities that became collectively recognized as a ‘Men’s Movement’. Nearly simultaneously the development of Contact Improvisation (CI), questioned many of the gender roles in traditional dance, allowing for a much broader range of physical interaction for both men and women. This article looks at intersections between these two ‘movements’ and argues that CI and related body-based performance practices were, and can continue to be, significant tools for social change.
Body-mapping and the Human Spirograph: Performance drawing in Thirdspace
Authors: Chittenden Tara 
Published: March 2015

Abstract
In performance drawing, the dancing body performs within particular kinds of spaces, leaving physical trace marks behind on surfaces such as plastic sheeting or paper. In this article I analyse Tony Orrico’s performance of 8 Circles (2010) to question the relationship between lived body and graphite mark. I draw on Soja’s theory of Thirdspace (1996) to rethink performance drawing as a bridge between different types of knowledge. This understanding of performance drawing reveals liminal spaces of heightened sensory and motor awareness where body, graphite and movement plane combine to become reflections on a body’s energetic flows, manifest as a body-map of somatic practice.
Interview with independent dance artist Cecilia Macfarlane
Authors: Meehan Emma , Macfarlane Cecilia 
Published: March 2015

Abstract
In this interview, independent dancer Cecilia Macfarlane talks about her project with the Japanese Contemporary Dance Network (JCDN) in 2013. To date, Macfarlane has undertaken eight trips to Japan, primarily to introduce her community dance practice to Japanese artists. However, during her visit in 2013, she was invited to learn folk dances from the north-east of Japan, in the Tohoku region most affected by the earthquake and tsunami in 2011. The interview is movingly interwoven with Macfarlane’s experience of losing her son. The sudden devastation following his death is described by Macfarlane as a ‘personal tsunami’, which is discussed alongside the loss and destruction wrought in Japan by earthquake, tsunami and nuclear devastation. In this way, autobiographical material is brought to bear on understanding the experiences of the survivors and to contribute to the development of Macfarlane’s artistic process alongside the project.
Reflections on somatic learning processes in higher education: Student experiences and teacher interpretations of Experiential Anatomy into Contemporary Dance
Authors: Glaser Laura 
Published: March 2015

Abstract
This article sets out to interpret documented experiences of students studying contemporary dance through the introduction of experiential anatomy. Processes of their learning build the basis for this evaluation, which is motivated by the teacher’s interest in the validity of a somatic approach to learning dance in 18+ pre-professional dance artists. In the immersive experience of learning experientially, reflection is integrated in the process and provides opportunities for meaning making. It also offers data for analysis: documents – which include drawings, journal entries and interviews – act as a feedback to the teacher and to the subject within this educational environment. Interwoven in the following article are student responses to somatic learning methods and processes, their experiences of embodiment and insights regarding the development of each student as a dancer, artist, person and learner.
Sensing possibility: Anatomy, sensation and dancing
Authors: Jenvey Nicole 
Published: March 2015

Abstract
This article discusses the question of bodily change in a research-based dance practice. The research was led by my admiration for certain dancers and their particular qualities of dancing, and my desire to bring other ways of moving into my body when I dance. Whilst anatomy forms the basis for conceptualizing processes of change, sensations are also the tools for and the subject of investigation as well as being evidence of or in research. Thus, I introduce the concept of ‘dancer’s anatomy’, my term for the combination of sensation, imagination and anatomical knowledge through which I consciously work on my dancing. In addition, a piece of choreography called Thematic, by Russell Dumas, together with my understanding of his practice, acts as a further research element that could be thought of as a kind of ‘control’ in the study. The research design called for repetition of this phrase over a two-year period such that the changes that were occurring in the body could be seen as those that occurred as a result of the dancing processes, and not as changes in the ‘choreography’. The article also documents how anatomy, dance movement and sensation mutually transform each other.
Soma in the City: How does listening and responding to a ‘somatic podcast’ affect one’s relationship to urban space?
Authors: Biggs Korina 
Published: March 2015

Abstract
This article describes a small piece of research carried out as part of an MA in Dance and Somatic Well–being at the University of Central Lancashire.
The basis of the research was: a)	An interest in bridging the gulf between somatic perceptual/movement practice and being in a challenging urban environment. b)	Curiosity in how using digital technology can possibly create more, rather than less, connection to psychophysical self and environment.
It assumed embodied person–environment mutuality and reciprocity, and was influenced by ecopsychology, the value of attending to movement, and by the somatic practices, particularly the Alexander Technique. The research methodology is influenced by Moustakas’ heuristic approach and involved an embodied first–person practice–led development of the content of the podcast. There were six participants and research ‘data’ was drawn from the time we shared together ‘post–podcast’. Conclusions were drawn from extracting themes from the subjective experience of the individuals.
The touch of sound: Dalcroze Eurhythmics as a somatic practice
Authors: Greenhead Karin , Habron John 
Published: March 2015

Abstract
Dalcroze Eurhythmics is a rich and multifaceted, living practice that has developed a wide range of applications and pedagogical approaches during more than a century of endeavour. Most researchers have situated this work within music education, dance and theatre history and therapy of various kinds. In this article we argue that it may also be considered a somatic practice owing to the ways in which movement, space, sensation, presence, touch and improvisation are central to the method. While recognizing that not all somatic practices include touch and improvisation, we focus on these aspects to explore the notion of the haptic nature of vision and sound, as they are manifest in the Dalcroze class. Drawing on practical examples of widespread practice within the Dalcroze community as well as personal experiences, we assert that the touch-like nature of sound not only makes contact with the body, inciting physical and emotional movement, but also develops awareness of self, others and environment due to the social nature of musical participation in general and of the rhythmics class in particular.

Symptoms on presentation include microangiopathic haemolytic anaemia, thrombocytopenia and organ damage. The most frequent direct causes of TMA are thrombotic thrombocytopenic purpura (TTP) and haemolytic uremic syndrome (HUS). The most common form of HUS is related to Shiga toxin producing
The High Order Method with Discrete TBCs for Solving the Cauchy Problem for the
1D Schrödinger Equation
Authors: Zlotnik Alexander , Zlotnik Ilya 
Published: March 2015

Abstract
We consider the Cauchy problem for the 1D generalized Schrödinger equation on the whole axis.
To solve it, any order finite element in space and the Crank–Nicolson in time method with the discrete transparent boundary conditions (TBCs) has recently been constructed.
Now we engage the global Richardson extrapolation in time to derive the high order method both with respect to space and time steps.
To study its properties, we comment on its stability and give results of numerical experiments and enlarged practical error analysis for three typical examples.
Unlike most common second order (in either space or time step) methods, the proposed method is able to provide high precision results in the uniform norm by using adequate computational costs.
It works even in the case of discontinuous potentials and non-smooth solutions far beyond the scope of its standard theory.
Comparing our results to the previous ones, we obtain much more accurate results using much less amount of both elements and time steps.
Island constraints and overgeneralization in language acquisition
Authors: Ambridge Ben 
Published: March 2015

AbstractAmbridge and Goldberg (2008) found that long distance dependency (LDD) questions (e.g., Who did she mumble that she saw?) do not seem to be formed by analogy with similar, more frequent sentences of the same type (e.g., What do you think X?; What did he say X?), but, rather, that such questions are acceptable to the extent that the main verb backgrounds the complement clause (e.g., say>mumble). Kalyan (2012) argued that this finding is compatible with a similarity-based account, provided that similarity between the verb and say/think is defined as similarity in the extent to which the verb backgrounds the complement clause. In the present article, I argue that Kalyan (2012) is correct, and that this phenomenon can be seen as an instance of a broader phenomenon whereby the fit between the properties of a particular item (e.g., a verb) and those of a particular construction slot (e.g., the VERB slot in the LDD question construction) is the primary determinant of the degree of (un)grammaticality of a possible generalization.

We prove in this paper the Ax–Lindemann–Weierstraß theorem for all mixed Shimura varieties and discuss the lower bounds for Galois orbits of special points of mixed Shimura varieties. In particular, we reprove a result of Silverberg [57] in a different approach. Then combining these results we prove the André–Oort conjecture unconditionally for any mixed Shimura variety whose pure part is a subvariety of

The Theory of Crisis after Crisis
Authors: Mladenović Igor , Kitanović Dragoslav 
Published: March 2015

Abstract
The global economic system and the world crisis are a reality, and hence the challenge for modern economic theory, which is to provide a valid response to its development and overcoming the crisis. The prevailing economic theory and methodology (neo-liberal paradigm) in this field demonstrates serious defects, so this paper attempts to show that the relative nature of economic theory is in expressing the social prejudices of its time. Demystification of the ideological and political foundations of what is today considered "objective knowledge" in the economy, is only possible with the affirmation of a new scientific methodology of economics, i.e. the new philosophy of economics. The aim of the paper is to stimulate thinking and different views on this subject.
