Symptoms of obsessive‐compulsive disorder in hospitalized eating disorder patients: A study using the maudsley obsessional‐compulsive inventory (MOCI)
Authors: Beumont Clare C. , Beumont Pierre J. V. , Touyz Stephen W. 
Published: June 2007

AbstractThirty‐one consecutive admissions with either anorexia or bulimia nervosa (DSM III R) were examined by the Maudsley Obsessional‐Compulsive Inventory (MOCI). Nutritional status was documented by Body Mass Index (BMI), eating disorder psychopathology by the Eating Attitudes Test (EAT) and the Eating Disorders Inventory (EDI) and depression by the Beck Depression Inventory (Beck). MOCI scores were significantly higher than normative values, conflicting with previous reports using the same instrument, but supporting earlier studies which had employed the Leyton Obsessional Inventory (LOI). The MOCI score correlated with three subscales in the EDI, but none of the other measures. There were no significant differences in MOCI scores between anorexia and bulimia nervosa patients, or between patients with restricting or purging presentations. As the MOCI is a measure of obsessive‐compulsive symtomatology, distinct both from those features of eating disorders which may resemble obsessional symptoms and from obsessional personality traits, the findings suggest a positive association of eating disorders with obsessivecompulsive disorder (OCD).
Experimental multipath component characteristics for short range urban propagation environments
Authors: Skentos N. D. , Marousis A. D. , Kanatas A. G. , Constantinou P. 
Published: June 2007

AbstractThis paper presents results on the parameters of multipath components extracted from wideband measured Multiple Input Multiple Output (MIMO) channel matrices. Experimental data were collected with wideband channel sounding measurements at 5.2 GHz in a microcell urban environment, under line of sight propagation conditions. The double directional and propagation delay parameter values of the dominant multipaths are estimated using the multidimensional parameter estimation algorithm. The results presented provide information in the context of parametric MIMO channel characterisation, refer to the number of identified waves and focus on the path weights' characteristics. Additionally, the extracted multipath estimates are used to synthesise MIMO matrices that are compared to the directly measured data. Copyright © 2007 John Wiley & Sons, Ltd.
Studies of fundamental physical–chemical mechanisms and processes of flame extinguishing by powder aerosols
Authors: Krasnyansky Mikhail 
Published: June 2007

AbstractTheoretical and experimental studies on mechanisms of interaction of the fire‐extinguishing aerosol with flame are carried out. The factors of heterogeneous inhibition of flame free radicals (O, OH, H, CHx) on a crystal surface of inorganic salts being the basic components of fire‐extinguishing powders and aerosols are measured using laboratory equipment. The semi‐empirical calculations by methods of quantum chemistry for heterogeneous and homogeneous inhibition reactions of burning are executed. The thermal mechanism for fire extinguishing is evaluated. The universal mechanism of influence on flame of a crystal surface of a fire‐extinguishing powder particle is offered.

What is the relationship between income inequality and health? Evidence from the BHPS
Authors: Lorgelly Paula K. , Lindley Joanne 
Published: June 2007

AbstractIncome inequality hypotheses propose that income differentials and/or income distributions have a detrimental effect on health. This previously well accepted relationship between inequality and health has recently come under scrutiny; some claim that it is a statistical artefact, arguing that aggregate level data are not sophisticated enough to adequately test for (and discriminate between) their existence. Supporters argue that it is a question of estimating the relationship using, amongst other things, an appropriate geographical scale. This paper adds to the debate by estimating the relationship between income inequality and health using individual panel data, exploring the relationship at the regional as well as the national level, while attempting to discriminate between the competing hypotheses. Pooled, random and fixed effects ordered probit models are exploited to estimate the relationship between self‐reported health and household income, income inequality and relative income. While the estimating regressions find support for the absolute income hypothesis, there is no support for the income inequality hypothesis or relative income hypothesis, and as such we argue that there is limited evidence of an effect of income inequality on health within Britain.

Scour around a side‐weir at a 30° section of a 180° alluvial curved channel
Authors: Ağaçcioğlu Hayrullah , Önen Fevzi , Toprak Z. Fuat 
Published: June 2007

AbstractLocal depths of clear‐water scour around side‐weirs
located at a 30° section of a 180° alluvial bend have been investigated experimentally in this paper. Relations between the depth of clear‐water scour as a function of time and approach flow intensity have been established. Regression analysis has been applied between the equilibrium depth of scour and the dimensionless parameters of approach flow intensity (V1/Vc, approach flow velocity/critical velocity at the threshold conditions of bed material), water head ratio ((h1− p)/h1, weir head over the side‐weir/water depth in the main channel), and weir crest height (b/p, width of main channel/side‐weir crest height) at θ = 30°. Although there is no scour when approach flow intensity is less than 0.55, the scour equilibrium depth increases almost linearly with the ratio of approach flow intensity, and the maximum value of scour depth occurs at a depth when the approach flow intensity is equal to 1.0 at the 30° section of a 180° alluvial curved channel. The location of the maximum scour hole occurs at the downstream of side‐weir sections close to the outer bank of the main channel and it moves toward the downstream direction with an increase of the dimensionless parameters of approach flow intensity as well as the water head ratio, the weir crest height and the side‐weir length (L/r, length of side‐weir/radius of main channel from the bend centre).

Electric field convergence versus atomic basis sets in all‐siliceous zeolites
Authors: Larin A. V. , Trubnikov D. N. , Vercauteren D. P. 
Published: June 2007

AbstractThe electrostatic potential (EP) and electric field (EF) are calculated in the TON and CHA zeolites using periodic hybrid B3LYP, PBE, and PW91 functionals considering eight basis sets. Relative root mean square differences between the EP or EF values estimated between the different basis sets are evaluated in several domains available for adsorbate molecules in both zeolites. The EP is interpreted in terms of ionicity of the framework. © 2007 Wiley Periodicals, Inc. J Comput Chem, 2008
Some constructions for block sequences of Steiner quadruple systems with error correcting consecutive unions
Authors: Momihara Koji , Jimbo Masakazu 
Published: June 2007

AbstractIn this article, we investigate a block sequence of a Steiner quadruple system which contains the blocks exactly once such that the collection of all blocks together with all unions of two consecutive blocks of the sequence forms an error correcting code with minimum distance four. In particular, we give two recursive constructions and obtain infinitely many such sequences by utilizing individual sequences as starters of the recursions. © 2007 Wiley Periodicals, Inc.

Teaching evidence‐based practice: Implications for psychology
Authors: Collins Frank L. , Leffingwell Thad R. , Belar Cynthia D. 
Published: June 2007

AbstractA movement advocating the use of evidence‐based practice (EBP) is increasingly influencing health care and the practice of psychology. Thus, teaching evidence‐based practice in psychology (EBPP) is critical to the preparation of future health service psychologists. In this article, the authors address common myths associated with EBP, propose core components involved in teaching EBPP, and describe an example of how such training can be incorporated into a professional psychology education and training curriculum. © 2007 Wiley Periodicals, Inc.

Evidence‐based practice in psychology: Perceptions of graduate students in scientist–practitioner programs
Authors: Luebbe Aaron M. , Radcliffe Alison M. , Callands Tamora A. , Green Debbie , Thorn Beverly E. 
Published: June 2007

AbstractThe evidence‐based practice movement in psychology (EBPP) is a relatively recent initiative to improve client care by integrating the best available research evidence with clinicians' expertise in the context of patient values and preferences. As this movement gains momentum in the field of psychology, training programs will likely need to modify their curricula to include training in the process of EBPP. An online survey was conducted of clinical psychology graduate students in programs that identified themselves as having a scientist–practitioner or clinical science model
(N = 1,195). Understanding of, experiences with, attitudes towards, and training in EBPP was assessed. Students had a generally favorable view of psychology's move toward EBPP. Although students reported a moderate amount of exposure to and experiences with EBPP, misunderstandings about the principles of EBPP were prevalent. Compared to students planning primarily clinical practice careers, students planning primarily clinical research careers were more favorable towards EBPP, expected EBPP to be more influential in their future careers, and were more likely to use research, but less likely to use client preferences to guide treatment planning. Recommendations for modifying training programs to promote EBPP are discussed. © 2007 Wiley Periodicals, Inc. J Clin Psychol 63: 643–655, 2007.
Bone formation following OP‐1 implantation is improved by addition of autogenous bone marrow cells in a canine femur defect model

Published: June 2007

AbstractOsteogenic Protein‐1 (OP‐1, BMP‐7) acts locally on connective tissue progenitors (CTPs) to induce bone formation. The response to OP‐1 and similar agents is potentially limited by the number of local CTPs. This study tested the hypothesis that supplementing local CTPs using autogenous bone marrow will enhance bone formation at an OP‐1 implant. Four 1.0‐cm diameter unicortical cylindrical defects in the left proximal femur were grafted in each of seven dogs. Radial ingrowth of new bone formation was assessed at 4 weeks using micro CT. The OP‐1 (3.5 mg rhOP‐1 in 1 g bovine collagen I matrix) was implanted in each site combined with either clotted blood or aspirated bone marrow (BM). Bone formation was increased in the group augmented with transplanted marrow. These data suggest that increasing the local population of cells and CTPs using aspirated bone marrow can enhance the performance of OP‐1, but may not eliminate the effects of site variation on the response to OP‐1 and similar agents. The canine multiple femoral defect model defined in this study is well suited to quantitatively evaluate strategies for augmenting bone repair using local cell targeting and cell transplantation strategies. © 2007 Orthopaedic Research Society.

Regenerative medicine in orthopaedic surgery
Authors: Corsi Karin A. , Schwarz Edward M. , Mooney David J. , Huard Johnny 
Published: June 2007

AbstractRegenerative medicine holds great promise for orthopaedic surgery. As surgeons continue to face challenges regarding the healing of diseased or injured musculoskeletal tissues, regenerative medicine aims to develop novel therapies that will replace, repair, or promote tissue regeneration. This review article will provide an overview of the different research areas involved in regenerative medicine, such as stem cells, bioinductive factors, and scaffolds. The potential use of stem cells for orthopaedic tissue engineering will be addressed by presenting the current progress with skeletal muscle–derived stem cells. As well, the development of a revascularized massive allograft will be described and will serve as a prototypic model of orthopaedic tissue engineering. Lastly, we will describe current approaches used to design cell instructive materials and how they can be used to promote and regulate the formation of bony tissue. © 2007 Orthopaedic Research Society.

Published: June 2007

AbstractGas diffusion properties of pear tissue are important in relation to gas exchange of the fruit with its environment during storage. In this contribution, a set‐up for measuring tissue diffusivity using fluorescent optical probes was developed. O2 and CO2 diffusivities were determined simultaneously based on a finite element model describing simultaneous O2 and CO2 gas transport as well as respiration in the tissue. The effect of variations on the diffusion set‐up conditions such as the volume of the measurement chamber and thickness of the sample on the accuracy of the estimated diffusivities was investigated using a sensitivity analysis on simulated data. The optical sensors produced good informative O2 and CO2 partial pressure versus time profiles. The average O2 and CO2 diffusivity of pear cortex tissue was (2.56 ± 0.48) × 10−10 m2 s−1 and (3.8 ± 1.1) × 10−9 m2 s−1, respectively. The coefficient of variation of diffusivity of O2 and CO2 in pear tissue due to bias, variation of the sample thickness and volume of the measurement chamber was 2.0–2.3% and 2.1–2.4% for a measurement chamber volume between 7.5 and 15 mL and a tissue thickness of 1–2.5 mm, respectively. The variability of estimated diffusivities due to measurement errors was eight times smaller than the biological variability. Copyright © 2007 Society of Chemical Industry
An implicit–explicit solution method for electro‐osmotic flow through three‐dimensional micro‐channels
Authors: Singh S. P. , Nithiarasu P. , Eng P. F. , Lewis R. W. , Arnold A. K. 
Published: June 2007

AbstractThis paper presents a comprehensive finite‐element modelling approach to electro‐osmotic flows on unstructured meshes. The non‐linear equation governing the electric potential is solved using an iterative algorithm. The employed algorithm is based on a preconditioned GMRES scheme. The linear Laplace equation governing the external electric potential is solved using a standard pre‐conditioned conjugate gradient solver. The coupled fluid dynamics equations are solved using a fractional step‐based, fully explicit, artificial compressibility scheme. This combination of an implicit approach to the electric potential equations and an explicit discretization to the Navier–Stokes equations is one of the best ways of solving the coupled equations in a memory‐efficient manner. The local time‐stepping approach used in the solution of the fluid flow equations accelerates the solution to a steady state faster than by using a global time‐stepping approach. The fully explicit form and the fractional stages of the fluid dynamics equations make the system memory efficient and free of pressure instability. In addition to these advantages, the proposed method is suitable for use on both structured and unstructured meshes with a highly non‐uniform distribution of element sizes. The accuracy of the proposed procedure is demonstrated by solving a basic micro‐channel flow problem and comparing the results against an analytical solution. The comparisons show excellent agreement between the numerical and analytical data. In addition to the benchmark solution, we have also presented results for flow through a fully three‐dimensional rectangular channel to further demonstrate the application of the presented method.

The Simpson–Golabi–Behmel syndrome causative Glypican‐3, binds to and inhibits the dipeptidyl peptidase activity of CD26

Published: June 2007

AbstractSimpson–Golabi–Behmel syndrome (SGBS) is an X‐linked condition shown to be the result of deletions of the glypican‐3 (GPC3) gene. GPC3 is a proteoglycan localized to the cell membrane via a glycosylphosphatidyl‐inositol (GPI) anchor. To further elucidate the GPC3 function(s), we have screened various cell lines for proteins that interact with GPC3, resulting in the isolation of a 115 kDa protein, identified as CD26. The interaction occurred with both the glycosylated and unglycosylated forms of GPC3 and led to the inhibition of CD26 peptidase activity. Moreover, introduction of CD26 into Cos‐1 cells was accompanied by the up‐regulation of cell growth, while inclusion of recombinant GPC3 in the media reduced the growth of CD26 transfected Cos‐1 cells, drastically. Furthermore, HepG2 C3A cells containing CD26 underwent apoptosis in the presence of recombinant GPC3 in both concentration and time‐dependant manner. In light of the fact that inhibition of CD26 reduces the rate of cell proliferation, we propose that a number of physical findings observed in SGBS patients may be a consequence of a direct interaction of GPC3 with CD26. Furthermore, GPC3 without the GPI anchor is capable of inducing apoptosis indicating that neither the GPI anchor nor the membrane attachment is required for apoptosis induction.

Published: June 2007

AbstractLike phosphorylation, protein sumoylation likely represents a dynamic PTM to alter protein function in support of cell regulatory systems. The broad‐spectrum impact of transient or chronic engagement of signal transduction cascades on protein sumoylation has not been explored. Here, we find that epidermal growth factor (EGF) stimulation evokes a rapid alteration in small ubiquitin modifier (SUMO) target selection, while oncogene expression alters steady‐state SUMO‐protein profiles. A proteomic SUMO target analysis in melanoma cells identified proteins involved in cellular signaling, growth control, and neural differentiation.

AbstractType II IFN exists as a single molecule (IFN‐γ) in contrast to type I IFN, of which there are a number of different forms. IFN‐γ is involved both directly and indirectly in antiviral activity, stimulation of bactericidal activity, antigen presentation and activation of macrophages. Recently IFN‐γ was cloned from a salmonid fish, the rainbow trout and a functional recombinant protein produced exhibited IFN‐γ activity. This recombinant IFN‐γ was used to stimulate an Atlantic salmon cell line, SHK‐1, to monitor the changes in protein expression by proteomic analysis 24 h after stimulation compared to unstimulated control cells. An SHK‐1 cell proteome map was developed and proteins altered in abundance by the IFN‐γ stimulation were identified. Under the analytical conditions used, 22 proteins were found to be altered in abundance, 15 increased and 7 decreased. Several proteins were excised from the gel and identified, following trypsin digestion and MALDI‐MS/MS/LC‐MS and database interrogation. Transcriptional analysis of five mRNAs encoding proteins increased in abundance by IFN‐γ in the proteome analysis was determined by real‐time PCR. We assessed the correlation between gene expression and change in abundance of proteins for these genes.

Published: June 2007

AbstractTo study the change in hepatic stellate cell (HSC) function under diabetic conditions, we cultured rat HSC in the presence of 5 and 30 mM glucose, which correspond to blood glucose concentrations during the early and late stages of diabetes, respectively. The differentially expressed HSC proteins were analyzed using 2‐DE and ESI‐Q‐TOF MS/MS and confirmed with Western blotting. The changed protein expression will provide greater understanding of glycolysis in HSC at the high concentration of glucose.

Published: June 2007

AbstractOxidatively modified low‐density lipoprotein (oxLDL) is one of the major factors involved in the development of atherosclerosis. Because of the insolubility of apolipoprotein B‐100 (apoB‐100) and the heterogeneous nature of oxidative modification, modified structures of apoB‐100 in oxLDL are poorly understood. We applied an on‐Membrane sample preparation procedure for LC‐MS/MS analysis of apoB‐100 proteins in native and modified low‐density lipoprotein (LDL) samples to eliminate lipid components in the LDLs followed by collection of tryptic digests of apoB‐100. Compared with a commonly used in‐gel digestion protocol, the sample preparation procedure using PVDF membrane greatly increased the recovery of tryptic peptides and resulted in improved sequence coverage in the final analysis, which lead to the identification of modified amino acid residues in copper‐induced oxLDL. A histidine residue modified by 4‐hydroxynonenal, a major lipid peroxidation product, as well as oxidized histidine and tryptophan residues were detected. LC‐MS/MS in combination with the on‐Membrane sample preparation procedure is a useful method to analyze highly hydrophobic proteins such as apoB‐100.
Glass transition temperature of allyl methacrylate‐n‐butyl acrylate gradient copolymers in dependence on chemical composition and molecular weight
Authors: París Rodrigo , De la Fuente José Luis 
Published: June 2007

AbstractGlass transition temperatures (Tgs) of P(AMA‐co‐BA) copolymers and the corresponding homopolymers, where AMA is allyl methacrylate and BA isn‐butyl acrylate, obtained by means of atom transfer radical polymerization were measured using differential scanning calorimetry. Because of the (pseudoliving) nature of this polymerization technique an increase in molecular weight (MW) is produced as the reaction progresses, which gives rise to an increase inTgs. This increment can be adequately described by the Fox–Flory's equation in both homopolymers. However, in the spontaneous gradient copolymers of P(AMA‐co‐BA), the expected increase inTgwith the augment of the monomer conversion is compensated by the enrichment of BA as the polymerization reaction progresses. These opposite effects with respect to theTgvalues almost balance each other, and therefore no significant influence on the MW or on conversion is found. This fact establishes thatTgs can be used to describe the profile of these gradient copolymers, and can be theoretically determined because of its dependence on the molar fraction in the copolymer. From this dependence on chemical composition along with the experimental behavior, a prediction of theTgvariation with the MW was performed. © 2007 Wiley Periodicals, Inc.
