The Ccr4-Not Complex Interacts with the mRNA Export Machinery
Shana C. Kerr,Nowel Azzouz,Stephen M. Fuchs,Martine A. Collart,Brian D. Strahl,Anita H. Corbett,R. Nicholas Laribee
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0018302
Abstract: The Ccr4-Not complex is a key eukaryotic regulator of gene transcription and cytoplasmic mRNA degradation. Whether this complex also affects aspects of post-transcriptional gene regulation, such as mRNA export, remains largely unexplored. Human Caf1 (hCaf1), a Ccr4-Not complex member, interacts with and regulates the arginine methyltransferase PRMT1, whose targets include RNA binding proteins involved in mRNA export. However, the functional significance of this regulation is poorly understood.
Obstructive sleep apnea: Screenings in primary, secondary and tertiary care settings  [PDF]
Atmaram Yarlagadda, Jayaprada Kasaraneni, Anita H. Clayton
Health (Health) , 2013, DOI: 10.4236/health.2013.58A2009
Abstract:

Insomnia is a major health problem affecting millions of people around the globe, particularly in the developed world, substantially impacting on individual work performance and raising disability costs. Insomnias can be broadly divided into primary and secondary types. Primary insomnias can further be divided into parasomnias and dyssomnias. Diagnostic approaches to insomnias can be challenging, thereby complicating the treatment process. Obstructive sleep apnea (OSA) falls under the category of primary insomnias and is a good example of frequently missed diagnoses. The goal of this paper is to document the development of a self-reporting sleep apnea scale based on graded percentage scores to correlate with primary, secondary and tertiary risks. Scores falling under fifty percent represent primary prevention risks of OSA and suggest possible interventions. A score of fifty percent highlights three core symptoms on the scale as described in detail below to represent early detection of OSA or secondary prevention. Finally, scores exceeding fifty percent will include associated risks of comorbidities as well as other factors contributing to OSA, or tertiary prevention, with separate scores assigned to individual risk factors. Analysis of final scores on the proposed scale would therefore, in our opinion help achieve the goal of grading the risk of OSA from a multidisciplinary preventive care aspect.

The dichotomy that faces nursing tutorial staff  [PDF]
Andrea M. Corbett
Open Journal of Nursing (OJN) , 2011, DOI: 10.4236/ojn.2011.11002
Abstract: There is a requirement for tutorial staff teaching on a degree programme to be engaged in research activity on a continuing basis. This is often in conflict with the demands that tutors in the Bachelor of Nursing programme are required to have academic ability and clinical skills whilst at the same time, engage in meaningful research activity. This does not occur. A study of the literature finds a commonality of this dichotomy throughout the world. A question is raised as to the impact of the increasing age of the nursing workforce; does this have an impact on the develop-ment of a research culture? It is suggested that the joint project approach adopted by the WITT (Western Institute of Technology at Taranaki) School of Nursing will assist in overcoming some of the identi-fied issues and begin the development of a research culture within the School that will be ongoing.
Gender Differences and Leadership Styles in a Non Secular Setting  [PDF]
Judith Corbett Carter
Open Journal of Leadership (OJL) , 2012, DOI: 10.4236/ojl.2012.11001
Abstract: Women are increasingly taking on the role of religious leaders despite some institutional barriers. Do ef- fective female clergy lead differently than effective male clergy? The focus of this study was to examine gender differences in the context of non secular leadership. The Multifactor Leadership Questionnaire (MLQ) styles and NEO-Five Factor Inventory (FFI) was used to measure leadership and personal charac- teristics of female and male pastors. Limited findings indicate that female pastors were higher in Open- ness and Charisma than male pastors.
Localization of proteins involved in endocytosis at tubulobulbar complexes in rat testes  [PDF]
Rahul D. Upadhyay, Anita Kumar, N. H. Balasinor
Advances in Reproductive Sciences (ARSci) , 2014, DOI: 10.4236/arsci.2014.21001
Abstract: Tubulobulbar Complexes (TBCs) are actin-rich structures formed between Sertoli-cells and spermatids at the time of sperm release. The main functions of the TBCs are to remove excess spermatid cytoplasm and acrosomal contents, internalize and recycle junctional complexes by endocytosis prior to spermiation. However, in addition to recycling some of the molecules undergo lysosomal degradation. The molecular machinery involved in endocytosis at the TBCs is not well understood. To bridge this gap localization of various proteins, involved at various steps of endocytosis studied in other systems, was demonstrated in TBCs using testicular fragmented material or sections by immunoblotting and immunofluroscence. The presence of key molecules like Vamp-2, syntaxin and Lamp-2 indicates occurrence of lysosomal degradation in addition to junctional recycling at the TBCs present at the time of sperm release. TBCs are endocytic devices functioning to recycle junctional molecules or remove spermatid cytoplasm that were present between spermatids and Sertoli-cells all through the process of spermatid maturation and in turn regulate male fertility.
MENTAL REPRODUCTION OF A DANCE CHOREOGRAPHY AND ITS EFFECTS ON PHYSIOLOGICAL FATIGUE IN DANCERS
Peter Blaser,Anita H?kelmann
Journal of Human Sport and Exercise , 2009,
Abstract: As stated at the start of this article, psychological and physical demand states can be understood as the effects and consequences caused by loads. To deduce the physiological characteristics of psychophysical demand, theoretical concepts like the load/demand concept are commonly used as a basis. Since demand itself is not directly quantifiable, reference must be made to demand indicators. This means measurement regulations determine what we define as psychophysical demand. The experiment described in this article falls under the category of mental (cognitive) demand that assumes knowledge exists about a dance choreography in the case of the persons being tested. This knowledge includes in particular, as well as conscious sense perceptions about events in the external world and one’s own body, mental activities such as thinking, imagining and remembering using emotional and motivational powers. These accentuate the focus for conscious actions. Particularly for the processes of thinking and remembering, attention increases concrete states of consciousness, which also manifest themselves in an increase in electrical activity of neurons in the frequencies. These phenomena could be discerned in all dancers and manifested themselves in similar ways. The states of consciousness are regenerated in the close interplay between cortical and limbic structures and are ultimately dependent on the function of the neuron collections. These functions are not only affected by external excitement, but also excite one another and combine with other cognitive excitement patterns such as memories, sensations, perceptions and imagination. At the same time, the neural states influence other vegetative functions such as heart, respiratory and muscle activities. In light of the question stated at the outset, the tendencies in the results confirm similar investigations proving that mental reproduction of motor actions affect all association areas of the cortex, despite the performance part of the action in the sense of its execution not being included. Since a large number of neural connections exist between the cortices, we can assume that the moment mental reproduction of a chain of actions takes place, such as a dance, a self-contained association area comes into being, in which the complex movement structures of the dance appear clearly in the form of increased beta activities. Furthermore, the increased neural activity due to mental concentration also leads, via the relevant vegetative connections, to a change in cardiac, respiratory and muscle activity. In this way, even
Low-temperature critical current of Y1-xCaxBa2Cu3O7-delta thin films as a function of hole content and oxygen deficiency
S. H. Naqib,Anita Semwal
Physics , 2005, DOI: 10.1016/j.physc.2005.05.012
Abstract: The effects of hole content (p) and oxygen deficiency (delta) on the zero-field critical current density, Jc0, were investigated for high-quality c-axis oriented Y1-xCaxBa2Cu3O7-delta (x = 0, 0.05, 0.10, and 0.20) thin films. Ca was used to introduce hole carriers in the CuO2 planes, independent of the oxygen deficiency in the CuO1-delta chains. Low-temperature Jc0(16K) of these films above the optimum doping were found to be high (> 10^7 Amp/cm^2) and were primarily determined by the hole concentration, reaching a maximum at p ~ 0.185+/-0.005, irrespective of oxygen deficiency. This implies that oxygen disorder plays only a secondary role and the intrinsic Jc0 is mainly governed by the carrier concentration and consequently by the superconducting condensation energy which also peaks at p ~ 0.19 where the pseudogap correlation vanishes.
COMBATING MYTHOLOGY AND CHANGING REALITY: THE DEBATE ON THE FUTURE OF EUROPE
Richard Corbett
Romanian Journal of European Affairs (RJEA) , 2001,
Abstract: As the enlargement of the EU fuels intense debate on the future of Europe, as a unified, single voiced and hopefully more efficient actor on a global scene, a clear cut assessment of the implications of such processes at national level is needed. As it enlarges its membership, the Union will become a macrocosm of progressively more diverse national interests, which need to dissolve into a unitary and articulated international presence. Against this background, the article looks at the implications of this process, within the framework of the powerful dichotomy federalism-centralism. Indeed, the EU is composed of strong member states with different cultures, which will retain large areas of their own competence; however, the author concludes, they will at the same time play a major role in the EU’s own decision taking, make it an unusually decentralized federation, and not a centralized superstate. In exploring the case of the UK, one of the most prominent actors within the Union which has difficulties coming to terms with its role within a wider Europe, the author attempts to demystify the euro-sceptic legends on Bruxelles taking over power from London and offer an objective overview of the institutions and processes that take place within this decentralized federation. The discussion on the future of Europe, the article concludes, should be translated from diplomatic channels to the citizens’ level, so that “they are at ease” with their union; and this will not be achieved through creating complex new institutions and multi tiered structures, but by objectively assessing, consolidating and improving what was achieved so far.

String structures and canonical 3-forms
Corbett Redden
Mathematics , 2009, DOI: 10.2140/pjm.2011.249.447
Abstract: Using basic homotopy constructions, we show that isomorphism classes of string structures on spin bundles are naturally given by certain degree 3 cohomology classes, which we call string classes, on the total space of the bundle. Using a Hodge isomorphism, we then show that the harmonic representative of a string class gives rise to a canonical 3-form on the base space, refining the associated differential character. We explicitly calculate this 3-form for homogeneous metrics on 3-spheres, and we discuss how the cohomology theory tmf could potentially encode obstructions to positive Ricci curvature metrics.
