Conformation ofα,α,α′‐Trisubstituted Cyclododecanone
Authors: Wang Ming‐An , Zhang Ning , Lu Hui‐Zhe , Wang Dao‐Quan 
Published: August 2007

AbstractTenα,α,α′‐trisubstituted cyclododecanones were synthesized and characterized by elemental analyses, infrared,1H NMR and13C NMR spectra, and X‐ray diffraction. NMR data could not give conformational information clearly, but some of their ring skeleton conformations of cyclododecanone moiety were showed to remain the unchanged [3333]‐2‐one conformation with little distortion, while the others were changed to the [3324]‐2‐one conformation in their crystal structures. These are consistent with the results of molecular mechanics calculation with Sybyl 6.9 software and Tripos force field, and semi‐empirical quantum calculation with AM1 method in Gaussian 98 software. Two geminal substituting groups are located atα‐corner carbon atom, and the third group is atα‐side‐exocarbon atom in both conformations. Both [3333]‐2‐one and [3324]‐2‐one conformations are present in a dynamic equilibrium in the solution, but only one preferred conformation exists in the crystal solid.
Static magnetic fields enhance skeletal muscle differentiation in vitro by improving myoblast alignment

Published: August 2007

AbstractStatic magnetic field (SMF) interacts with mammal skeletal muscle; however, SMF effects on skeletal muscle cells are poorly investigated. The myogenic cell line L6, an in vitro model of muscle development, was used to investigate the effect of a 80 ± mT SMF generated by a custom‐made magnet. SMF promoted myogenic cell differentiation and hypertrophy, i.e., increased accumulation of actin and myosin and formation of large multinucleated myotubes. The elevated number of nuclei per myotube was derived from increased cell fusion efficiency, with no changes in cell proliferation upon SMF exposure. No alterations in myogenin expression, a modulator of myogenesis, occurred upon SMF exposure. SMF induced cells to align in parallel bundles, an orientation conserved throughout differentiation. SMF stimulated formation of actin stress‐fiber like structures. SMF rescued muscle differentiation in the presence of TNF, a muscle differentiation inhibitor. We believe this is the first report showing that SMF promotes myogenic differentiation and cell alignment, in the absence of any invasive manipulation. SMF‐enhanced parallel orientation of myotubes is relevant to tissue engineering of a highly organized tissue such as skeletal muscle. SMF rescue of muscle differentiation in the presence of TNF may have important therapeutic implications. © 2007 International Society for Analytical Cytology
Environmental regulation and modelling of cassava canopy conductance under drying root‐zone soil water
Authors: Oguntunde Philip G. , Alatise Michael O. 
Published: August 2007

AbstractSap flow was measured, with Granier‐type sensors, in a crop of field‐grown water‐stressed cassava (Manihot esculenta Crantz) in Ghana, West Africa. The main objective of this study was to examine the environmental control of canopy conductance (gc) with a view to modelling the stomatal control of water transport under water‐stressed condition. Weather variables measured concurrently with sap flow were: air temperature (Ta), relative humidity (RH), wind speed (u) and solar radiation (Rs). Relationship between canopy conductance (gc) and vapour pressure deficit (Dε) was curvilinear while no specific pattern was observed with Rs. Average diurnal gc decreased from 3.0 ± 0.6 to 0.7 ± 0.4 mm s−1 between 0730 and 2000 h local time ( = GMT) each day. A Jarvis‐type model, based on a set of environmental control functions, was parameterized for the cassava crop in this study. Model results demonstrated that gc was estimated with a high degree of accuracy based on Rs, Ta, and Dε (r2 = 0.92;F = 809.2;P < 0.0001). Dε explained about 90% (F = 2129.7;P < 0.0001) of the variations observed in gc, whereas both Rs and Ta contributed about 2% of the explained variance in gc. The aerodynamic conductance (ga) was very high compared to gc, leading to a daily average ratio ga/gc > 100 and a decoupling factor < 0.1. Cross‐validation analysis revealed a consistent good performance (r2 > 0.85) of the gc model with Dε as the only independent environmental variable. Copyright © 2007 Royal Meteorological Society
Benefits of promulgating higher resolution wind data for airline route planning
Authors: Lunnon R. W. , Mirza A. K. 
Published: August 2007

AbstractA study has been undertaken to determine whether there are useable incremental benefits from providing upper air wind data at high horizontal resolution to the process of airline flight planning. Currently winds are provided on a horizontal resolution of approximately 140 km. The study looked at resolutions varying between 160 and 40 km. A theoretical calculation was undertaken using published variance power spectra, which quantify the wind variability as a function of horizontal scale. This calculation also used a published formula for the time saving in flying across an area of constant vorticity. The results of the theoretical calculation were expressed in terms of the time saving on a transatlantic flight lasting typically 8 h stemming from a resolution change from 160 to 80 km. In this case the answer was well under one second. It is thought that such a small incremental benefit could not be used to justify the practical steps needed to exploit high resolution data. The more practical part of the study involved running an optimum routes diagnosis package with variable resolution input data. Input data at resolutions of 160 and 40 km were considered. Although this approach was only applied to a restricted number of cases and routes, it confirmed the theoretical result. © Crown Copyright 2007.

Induction of endoreduplication by a JNK inhibitor SP600125 in human lung carcinoma A 549 cells
Authors: Miyamoto‐Yamasaki Yumi , Yamasaki Masao , Tachibana Hirofumi , Yamada Koji 
Published: August 2007

AbstractThe effect of the pan c‐Jun N‐terminal kinase (JNK) inhibitor SP600125 on the proliferation of human lung carcinoma A549 cells has been evaluated. We have shown that SP600125 completely inhibited the proliferation of A549 cells, the cycle arrest being in G2/M phase. When cells were treated with SP600125 for >12 h, a cell population with DNA content of 4n to 8n was detected. Moreover, the effect of SP600125 on the expression of cell cycle related proteins was an upregulation of p53 protein accompanied by an increase in its molecular mass. Prolonged SP600125 treatment downregulated p21, Bax and Mdm2 expression, but increased the level of the cellular p53–Mdm2 complex. Taken together, we show that SP600125 could induce G2/M cell cycle arrest and endoreduplication in a p21 independent manner, and that SP600125 could also post‐translationally modify p53 to modify its function. Our data show that basic JNK activity plays an important role in the progression of the cell cycle at G2/M cell phase.
Modelling of road surface temperature from a geographical parameter database. Part 2: Numerical
Authors: Chapman Lee , Thornes John E , Bradley Andrew V 
Published: August 2007

AbstractA new ice prediction strategy is presented based on the numerical modelling of surveyed geographical parameters. This approach enables the thermal projection of road surface temperatures across the road network entirely by model predictions and without the need for thermal maps. The influence of eight geographical parameters (latitude, altitude, sky‐view factor, screening, roughness length, road construction, traffic density and topography) is investigated by means of sensitivity analyses. The sky‐view factor is highlighted as the dominant control on road surface temperature, particularly at high levels of atmospheric stability. A numerical road weather model incorporating all eight parameters was run over 20 nights using forecast and retrospective meteorological data. The model has the ability to explain up to 72% of the variation in road surface temperature purely by thermally projecting surface temperature using geographical variables. Retrospective results produce an average r.m.s. error of $1\ ^{\circ}\hbox{C}$ which is comparable to existing UK road weather models. Copyright © 2001 Royal Meteorological Society

Psychological change from the inside looking out: A qualitative investigation
Authors: Carey Timothy A. , Carey Margaret , Stalker Kirsten , Mullan Richard J. , Murray Lindsey K. , Spratt Margaret B. 
Published: August 2007

AbstractRegardless of the type of psychotherapy considered, change is the predominant goal. Psychotherapies differ in their explanations of how change occurs and what it is that needs to change, but pursuing change of something in some way is common. Psychotherapeutic methods, therefore, should be enhanced as knowledge of the change process improves. Furthermore, improving our knowledge about general principles of change may be of greater benefit to psychotherapy than increased knowledge about any particular change technique. This study addresses the questions ‘What is psychological change?’ and ‘How does it occur?’ from patients’ viewpoints. Answers to these questions were sought using qualitative methodology. At the end of treatment, 27 people were interviewed about their experience of change. Interviews were taped and transcripts analysed using the Framework approach. Change occurred across three domains: feelings, thoughts and actions. Participants described change as both a gradual process and an identifiable moment. In relation to how change occurred, six themes emerged: motivation and readiness, perceived aspects of self, tools and strategies, learning, interaction with the therapist and the relief of talking. Change was experienced in similar ways irrespective of type of treatment. Current stage models of change may not be suited to the explanations of change provided by the participants of this study; the process of insight through reorganization might be a more accurate explanation. Understanding change as a process involving sudden and gradual elements rather than a process occurring through sequential stages could inform the development of more efficacious psychological treatments.

Published: August 2007

AbstractPupils (n=99) from two secondary schools in the UK were interviewed to investigate their views and experiences of the peer counselling for bullying service set up in their school. They were asked about various things concerning (1) the characteristics of the service and service providers that they valued and (2) their reasons for not using the service. Overall, a majority of participants reported a willingness to use this type of service and they identified numerous characteristics that they valued, including peer counsellors with good listening skills who were trustworthy and maintained confidentiality. A noteworthy proportion of participants also wanted the service to provide advice on solving bullying‐related problems. Some barriers to using the service were also identified, including fear of being stigmatised. Responses offered by girls and boys, and by users and non‐users of the service, were compared and several significant differences emerged. The results are discussed in terms of the implications for adults who run this type of service and the peer counsellors who deliver it.
Pragmatic evaluation of the viability of CCBT self‐help for depression in higher education
Authors: Mitchell Nicky , Dunn Kate 
Published: August 2007

AbstractThis study explores the potential of a computerised cognitive behavioural therapy (CCBT) self‐help programme for depression within the context of a Higher Education Counselling Service. It seems timely to consider the place of evidence‐based alternatives to the face‐to‐face counselling traditionally provided in higher education with user choice in mind. There is also a need to cater for increasing numbers of students experiencing a wide range and severity of emotional difficulties, sometimes resulting in long waiting periods for help. In the study twelve depressed students used the CCBT programme ‘Beating the Blues’™. Ten (83.3%) participants completed the programme. Initial credibility of and expectancy‐for‐improvement from the intervention was high. Significant reductions in depression scores were found following completion, whilst anxiety scores changes were not significant. Feedback on the programme was largely positive. CCBT was clearly preferred to face‐to‐face counselling by some participants, supporting the need for a choice of interventions for students. These results suggest that CCBT may be an acceptable and effective intervention for a number of depressed students. It is argued that CCBT may be a viable addition to current provision in Higher Education Counselling Services and that further studies are required to investigate this further.
Clients with borderline personality disorder: Exploring their experiences of dialectical behaviour therapy
Authors: Hodgetts Alison , Wright John , Gough Anna 
Published: August 2007

AbstractThis study explores clients’ experiences of Dialectical Behavioural Therapy (DBT). Five participants, all with a diagnosis of borderline personality disorder, were interviewed following a semi‐structured format about their experiences of an NHS regional DBT programme. The interviews were transcribed and analysed using Interpretative Phenomenological Analysis (IPA). Three superordinate themes were identified consisting of a number of sub themes: joining a DBT Programme (external and internal factors); experience of DBT (specific and non specific factors); and evaluation of DBT (change, evaluation and role of the past and future). The study provides an insight into clients’ experiences of DBT. The results are discussed in relation to clinical practice and future research.
