Factorial validation of a French short‐form of the Working Alliance Inventory
Authors: Corbière Marc , Bisson Jocelyn , Lauzon Sylvie , Ricard Nicole 
Published: March 2006

AbstractEvaluation of the therapeutic alliance is crucial for understanding the therapeutic process and its results. However, few instruments are available in French. This article aims to validate a French short form of the Working Alliance Inventory (WAI). Unlike other questionnaires, the WAI is the most widely used in psychotherapy research as well as in social psychiatry. Confirmatory factor analyses were carried out on a sample of 150 client‐case manager dyads in order to determine the validity of this short‐form instrument. The results of these confirmatory factor analyses allowed us to answer different authors' questions (Horvath and Greenberg, 1989; Tracey and Kokotovic, 1989) regarding the factorial structure of the WAI. The results also indicated a unidimensional solution as being the most valid for the two samples. We suggest that, in future studies, only one score be considered for the evaluation of the WAI. We also suggest modifying two statements in the English and French versions in order to render a faithful comparison between the therapist and client versions.

An inverse heat conduction problem with heat flux measurements
Authors: Loulou Tahar , Scott Elaine P. 
Published: March 2006

AbstractUsing heat flux measurements as additional information to solve inverse heat conduction problems was and is still rarely employed. Lot of disadvantages linked to heat flux measurement specificities (local disturbance, intrusive measurement, lack of knowledge and proficiency, etc.) make people prefer temperature measurements which are well documented and very widespread. Solving inverse heat conduction problems with heat flux measurements is quite different than the one which uses temperatures and need to be investigated deeply. In this work, this problem is approached through the solution of a bioengineering problem consisting in the development of a non‐invasive blood perfusion probe. The effort here is focused on the development of a methodology for the estimation of time‐dependent blood perfusion from heat flux measurements. The physical probe incorporates a thin heat flux sensor, which is placed in contact with the tissue region where the perfusion is to be measured. The sensor records the heat flux due to an imposed thermal event, which is achieved by air flow. A one‐dimensional mathematical model is used to simulate the thermal event occurring at the contact region holding between the probe and the tissue. A combined parameter and function estimation procedure is developed to estimate simultaneously time‐dependent blood perfusion and thermal contact conductance between the probe and the tissue. The robustness of the method was demonstrated through several test cases using simulated data. The presented examples include various functional changes in the time evolution of blood perfusion. Results from this study have shown the feasibility of solving inverse problems with heat flux measurements and the two unknowns are estimated with no a priori information about their functional forms.

Boundary element frequency domain formulation for dynamic analysis of Mindlin plates
Authors: Wen P. H. , Aliabadi M. H. 
Published: March 2006

AbstractA new boundary element formulation for analysis of shear deformable plates subjected to dynamic loading is presented. Fundamental solutions for the Mindlin plate theory are derived in the Laplace transform domain. The characteristics of the three flextural waves are studied in the time domain. It is shown that the new fundamental solutions exhibit the same strong singularity as in the static case.Two numerical examples are presented to demonstrate the accuracy of the boundary element method and comparisons are made with the finite element method.

A convergent adaptive finite element method for the primal problem of elastoplasticity
Authors: Carstensen Carsten , Orlando Antonio , Valdman Jan 
Published: March 2006

AbstractThe boundary value problem representing one time step of the primal formulation of elastoplasticity with positive hardening leads to a variational inequality of the second kind with some nondifferentiable functional. This paper establishes an adaptive finite element algorithm for the solution of this variational inequality that yields the energy reduction and, up to higher order terms, the R‐linear convergence of the stresses with respect to the number of loops. Applications include several plasticity models: linear isotropic‐kinematic hardening, linear kinematic hardening, and multisurface plasticity as model for nonlinear hardening laws. For perfect plasticity, the adaptive algorithm yields strong convergence of the stresses. Numerical examples confirm an improved linear convergence rate and study the performance of the algorithm in comparison with the more frequently applied maximum refinement rule.

Characteristic‐based split (CBS) algorithm finite element modelling for shallow waters in the Venice lagoon
Authors: Morandi‐Cecchi M. , Venturin M. 
Published: March 2006

AbstractIn this paper, the characteristic‐based split (CBS) algorithm is presented to solve water motion problem due to tides in the Venice lagoon. The basic equations are the well‐known vertically integrated shallow‐water equations expressed in terms of total water depth and horizontal velocities. The approximation of any additional scalar variables, such as temperature, concentration or pollutant dispersion from the appropriate advection–diffusion governing equations is also outlined. Numerical results illustrate the performance of the proposed algorithm on both advection–diffusion and shallow‐water problems. Copyright © 2006 John Wiley & Sons, Ltd.

Authors: Trevisan F. , Kettunen L. 
Published: March 2006

AbstractThis paper gives an explicit geometric interpretation of finite element formulations of the eddy‐current problem. The paper shows, step‐by‐step how the eddy‐current problem can be implemented in a finite element kind of software system exploiting familiar geometric ideas such as lengths of edges, areas of faces, volumes of tetrahedra, and the mutual interconnections between the simplices of a mesh. The approach is a specific case of the so‐called geometric techniques. Copyright © 2006 John Wiley & Sons, Ltd.

Published: March 2006

AbstractBackgroundExtramedullary infiltration (EMI) is an occasional clinical symptom in childhood acute myelogenous leukemia (AML), but there is considerable controversy regarding the prognostic significance of EMI in AML.ProcedureWe evaluated the frequency and prognostic significance of EMI at diagnosis of AML in children.ResultsOf 240 cases of de novo AML excluding children with Down syndrome and acute promyelocytic leukemia, 56 (23.3%) showed EMI at diagnosis. Patients with EMI had a higher initial WBC count and a higher proportion of M4/M5 morphological variants. The complete remission rate following induction chemotherapy was lower in patients with EMI. However, the overall survival and event‐free survival did not differ between patients with and without EMI. A detailed analysis showed that patients with EMI with a WBC count at diagnosis of over 100 × 109/L or infiltration into the central nervous system are likely to have a poor prognosis.ConclusionsCNS leukemia and EMI together with a WBC count of >100 × 109/L at diagnosis of AML are high risk factors for relapse, and alternative treatment approaches for patients with these characteristics should be explored.

AbstractRadiation therapy is often used to achieve local control of pelvic Ewing sarcoma in children. The effects of radiation on the female reproductive tract have been well documented in adults with gynecological malignancies, but the long‐term consequences of pelvic radiation in pre‐pubertal or adolescent girls are not as well described. We report a case of hematometrocolpos developing in an adolescent previously treated with chemotherapy and radiation therapy for pelvic Ewing sarcoma. We describe the clinical presentation, radiographic features, gross pathology, treatment strategies, outcome, as well as putative predisposing factors and preventative interventions.

A preliminary study of peritraumatic dissociation, social support, and coping in relation to posttraumatic stress symptoms for a parent's cancer
Authors: Wong Melisa , Looney Elizabeth , Michaels Jennifer , Palesh Oxana , Koopman Cheryl 
Published: March 2006

AbstractThis study examined predictors of posttraumatic stress disorder (PTSD) symptoms in adults who, as children, had a parent diagnosed with cancer. Possible predictors of adulthood PTSD examined were peritraumatic dissociation, satisfaction with social support, coping through denial, behavioral disengagement and self‐distraction, and whether or not the parent died. Thirty research participants (20 women and 10 men, ages 18–38) were recruited who were 8–17‐years old at the time of a parent's cancer diagnosis. Each participant completed measures of their current PTSD symptoms in response to their parent's cancer, peritraumatic dissociative experiences, demographic characteristics, and satisfaction with social support and use of coping strategies at the time of their parent's cancer diagnosis. Seventeen percent met screening criteria for likely PTSD. As hypothesized, PTSD symptoms were strongly and positively correlated with peritraumatic dissociation. Furthermore, PTSD symptoms were greater among females and were related to greater use of denial and behavioral disengagement and to less satisfaction with social support. These results suggest that health care providers need to recognize symptoms of peritraumatic dissociation in the children of parents who are diagnosed with cancer so that steps can be taken to minimize the children's development of PTSD that may extend into their adult lives.

Asthmatic patients' views of a comprehensive asthma rehabilitation programme: a three‐year follow‐up
Authors: Emtner Margareta , Hedin Anna , StÅlenheim Gunnemar 
Published: March 2006

AbstractBackground and PurposeTwenty‐one asthmatic patients aged 27–59 years, with mild to moderate asthma, participated in a 10‐week group rehabilitation programme covering physical training and theoretical and practical education in medication, self‐management strategies and physiotherapy. This study was undertaken retrospectively to investigate (1) the patients' reasons for joining the programme, (2) their experiences of the programme, and (3) their ways of coping with disease‐related problems before joining and three years after completion of the programme.MethodsPatients were followed up every six months for three years and were interviewed after the three years. The semi‐structured interviews were tape‐recorded, transcribed and revised.ResultsThe life‐situation of most of the patients before the 10‐week programme was characterized by helplessness at exacerbations, anxiety/insecurity about medications and their side‐effects, and/or concern about future health. More than half of the subjects felt physical limitations in daily life or when exercising. All wished to increase their knowledge of asthma by joining the programme, but only nine patients expected asthma improvement. The experience that they were able to carry out physical exercise to a maximal intensity and that physical training improved their asthma, with increased knowledge about medications were mentioned by all as the most valuable effects of the programme. Moreover, most patients emphasized their increased ability in self‐management strategies (stress reduction and breathing technique). The increased knowledge and improved practical skills contributed to a better life‐situation after the rehabilitation. After the three years virtually all the patients' lives were characterized by improved self‐management, increased physical activity and a sense of security. Almost half of them expressed a wish to take responsibility for the disease.ConclusionsIn addition to medical therapy and education, physical training and techniques for relaxation and breathing should form part of the treatment of asthma.

Physiological response to a short period of exercise training in patients with chronic heart failure
Authors: Taylor Ann 
Published: March 2006

AbstractBackground and PurposeWhilst cardiac rehabilitation is regularly offered to patients recovering from a myocardial infarction, people with chronic heart failure are often excluded from exercise training programmes. This study was designed to investigate the effects of eight weeks' exercise training in patients with moderate chronic heart failure.MethodEight male patients entered a 16‐week randomized, controlled, crossover study of two months' exercise training versus a control period. They performed supervised training three times a week and measures of indices of aerobic function and exercise tolerance were performed monthly throughout the study period.ResultsAfter training, the time walked on a treadmill during an exercise tolerance test increased from 14.8 min (95% CI; range 10.4–18.1 min) to 15.9 min (range 12.1–15.9 min). Significant changes at peak exercise levels (p<0.05) were seen in oxygen uptake, increasing from 3.4 metabolic equivalents (METs) (95% CI; range 2.6–4.2 METs) to 4.0 METs (range 3.2–4.9 METs), and in cardiac index, improving from 5.0 l/min−1/m−2 (95% CI; range 2.9–8.1 l/min−1/m−2) to 5.5 l/min−1/m−2 (range 3.0–9.4 l/min−1/m−2). Resting heart rate decreased significantly (p<0.05), from 84 beats/min−1 (95% CI; range 73–105 beats/min−1) to 76 beats/min−1 (range 64–90 beats/min−1). Blood flow measurements by venous occlusion plethysmography showed a 21.5% decrease (range 58.5–238.9%) in resting blood flow to the lower leg and a 31.6% increase (range −7.2% to 52.5%) after submaximal exercise, but these changes were not significant (p>0.05). All benefits were lost within two months of ceasing regular exercise.ConclusionThis study demonstrated that patients with moderate chronic heart failure derived beneficial physiological responses from eight weeks' exercise training, but these were soon lost after cessation of regular exercise.

AbstractThe methanol extract of stems of Catalpa ovata G Don exhibits potent in vivo antifungal activity against Magnaporthe grisea (Hebert) Barr (rice blast) on rice plants, Botrytis cinerea Pers ex Fr (tomato grey mould) and Phytophthora infestans (Mont) de Bary (tomato late blight) on tomato plants, Puccinia recondita Rob ex Desm (wheat leaf rust) on wheat plants and Blumeria graminis (DC) Speer f. sp. hordei Marchal (barley powdery mildew) on barley plants. An antifungal substance was isolated and identified as dehydro‐α‐lapachone from mass and nuclear magnetic resonance spectral data. It completely inhibited the mycelial growth of B. cinerea, Colletotrichum acutatum Simmonds, Colletotrichum gloeosporioides Simmonds, M. grisea and Pythium ultimum Trow over a range of 0.4‐33.3 mg litre−1. It also controlled the development of rice blast, tomato late blight, wheat leaf rust, barley powdery mildew and red pepper anthracnose (Colletotrichum coccodes (Wallr) S Hughes). The chemical was particularly effective in suppressing red pepper anthracnose by 95% at a concentration of 125 mg litre−1. Copyright © 2006 Society of Chemical Industry

Published: March 2006

AbstractThe pine processionary moth Thaumetopoea wilkinsoni Tams is a serious pest on pine trees in southwestern Turkey. The efficacy of a naturally derived insecticide, spinosad, on fourth‐fifth instar larvae of T. wilkinsoni was studied under laboratory conditions. The product exhibited strong larvicidal activity and at doses above 5 mg litre−1 caused >90% mortality in the fourth–fifth larval stages of the species after 72 h. At 72 h the LD50 and LD90 values were 3.26 and 5.69 mg litre−1 respectively. The results showed that spinosad is highly effective on T. wilkinsoni larvae.

Biochemical analysis of a chlorfenapyr‐selected resistant strain of Tetranychus urticae Koch
Authors: Van Leeuwen Thomas , Van Pottelberge Steven , Tirry Luc 
Published: March 2006

AbstractTetranychus urticae Koch has recently developed resistance to chlorfenapyr in Australia and Japan, but no attempt has yet been made to describe the biochemical mechanisms involved in chlorfenapyr resistance. In this study a laboratory‐selected chlorfenapyr‐resistant strain was investigated. Resistance to chlorfenapyr was associated with a strong increase in esterase activity and P450 mono‐oxygenase (MO) activity but a decrease in 3,3′,5,5′‐tetramethylbenzidine (TMBZ) peroxidation activity. Differences in esterase activities between susceptible and resistant strains increased with increasing carbon number of the aliphatic side‐chain of the nitrophenol substrate. A 4.4‐fold increase in the O‐deethylation of 7‐ethoxy‐4‐trifluoromethyl coumarin (7‐EFC) mediated by P450 MOs was detected. Remarkably, the resistant strain showed only half of the total TMBZ peroxidation activity found in the susceptible strain. The activity of these enzymes was further determined on different crosses and back‐crosses of both strains. Results indicated that activities correlated with chlorfenapyr susceptibility and could be considered as biochemical markers. Esterase isozymes of both strains and their crosses were separated with isoelectric focusing (IEF) and visualised after activity staining. It was clear that two distinct zones of enhanced esterase activity were present in the chlorfenapyr‐resistant strain (EST 11, pI = 4.88 and EST 16, pI = 4.71). EST 11 was identified with inhibitors as a carboxylesterase. The relative presence and intensity of these esterase zones changed in the different crosses and could be seen as a marker for chlorfenapyr resistance. Glutathione‐S‐transferase and glucose‐6‐phosphate dehydrogenase activities were not significantly different between strains. A twofold decrease in TMBZ peroxidase activity in the resistant strain could reflect decreased activation of chlorfenapyr. On the basis of these results the involvement of P450 MOs and esterases in the activation and detoxification of chlorfenapyr in T. urticae is challenged and discussed.

Efficacy of noviflumuron gel bait for control of the German cockroach,Blattella germanica(Dictyoptera: Blattellidae)—laboratory studies
Authors: Wang Changlu , Bennett Gary W 
Published: March 2006

AbstractThe insecticidal activity of a cockroach gel bait containing a chitin synthesis inhibitor, noviflumuron, was evaluated using laboratory and field strains of the German cockroach,Blattella germanica(L.). Noviflumuron gel bait (0.01–5 mg g−1) caused ≥90% nymphal mortality to laboratory and field strains ofB. germanicain choice tests after 11 and 19 days of continuous exposure respectively. In 1 m × 1 m bioassay arenas, laboratory strainB. germanicapopulation levels exposed to 5 mg g−1noviflumuron bait or 0.1 mg g−1fipronil gel bait were significantly lower than untreated population levels after 3 weeks and 1 week of exposure respectively. Various noviflumuron bait exposure periods (2, 4 and 7 weeks) caused similar population reductions, with a mean of 99.3 (± 0.3)% at 7 weeks. Fipronil gel bait caused 100% population reduction at 2 weeks post‐exposure. The control population increased 89.0% at 7 weeks. In a simulated kitchen experiment with mixed stage laboratory populations, cockroach trap catches decreased 96.8 (± 2.0)% at 8 weeks in the 0.5 mg g−1noviflumuron bait treatment. The trap catches in the control increased 506.5 (± 493.7)% during the same period. Trap catch reduction by 0.1 mg g−1fipronil gel bait reached 100% at 4 weeks. Noviflumuron bait caused significantly lower nymph/total ratios toB. germanicapopulations in bioassay arenas from 2 weeks after exposure, demonstrating its effectiveness as a control agent forB. germanicawith a pattern of activity similar to that expected from a chitin synthesis inhibitor.

Preliminary approaches for the development of a high‐performance liquid chromatography/electrospray ionization tandem mass spectrometry method for the detection and label‐free semi‐quantitation of the main storage proteins of Lupinus albus in foods
Authors: Locati Daniela , Morandi Sheila , Zanotti Marco , Arnoldi Anna 
Published: March 2006

AbstractSince recent literature has indicated that white lupin (Lupinus albus) may be a useful source of hypocholesterolemic proteins to be used in functional food formulation, our final goal is the development of a fast and automated high‐performance liquid chromatography/electrospray ionization tandem mass spectrometry (HPLC/ESI‐MS/MS) method for the detection and the label‐free semi‐quantitation of the main lupin globulins in lupin foods and food ingredients. We present here some preliminary results in this direction. As a first step a total protein extract (TPE‐WF) from lupin flakes was pre‐fractionated by anion‐exchange chromatography and each fraction was digested with trypsin and analyzed by HPLC/ESI‐MS/MS. Subsequently, the tryptic digest of TPE‐WF was directly analyzed by HPLC/ESI‐MS/MS without any pre‐fractionation. Eventually, in order to test the applicability of the method to real samples, a lupin beverage and two lupin protein isolates were analyzed. Both Mascot and Spectrum Mill MS Proteomics Workbench software were used to identify the protein composition in these samples and Spectrum Mill was used also to test the possibility of developing a label‐free semi‐quantitation method based on peptide hits. Encouraging results were obtained especially in the detection of the hypocholesterolemic component β‐conglutin. Copyright © 2006 John Wiley & Sons, Ltd.
