Shame and pride in anorexia nervosa: a qualitative descriptive study
Authors: Skårderud Finn 
Published: January 2007

AbstractDuring the last decades, there has been a rising interest in the role of shame in psychiatric disorders.ObjectiveTo define shame and describe types and subtypes of shame and their relations to symptoms and meaning in anorexia nervosa. The study will also describe the possible role of pride, as a contrasting emotional and cognitive experience.MethodThirteen female patients (age 16–39 years) with anorexia nervosa were interviewed about their general understanding of the concept of shame, what they considered shameful in themselves, past and present, and in others and shame related to eating and body.ResultsBased on statements from the patients ‘globalised internal shame’, different subtypes of focal shame and different subtypes of pride are categorised. Shame is described both as cause and consequence in relation to symptoms in anorexia nervosa, hence a shame–shame cycle. A shame–pride cycle is also presented.DiscussionThe use of shame, as well as pride, as concepts in regard to anorexia nervosa may improve our understanding of the nature of this disorder, as well as being a guideline for therapists.

Authors: Yousefi G. Reza , Seifi Hossein , Shirmohammadi Dariush 
Published: January 2007

AbstractIn deregulated electricity markets, reactive power is one of the ancillary services that is provided by the Independent System Operator (ISO). In this paper we propose a new algorithm to ‘tune’ reactive power resources with the objectives of minimizing active power losses and optimizing system voltage profile and stability. In our solution, we assume that reactive power resources are either owned by or are under long‐term contracts with the ISO. The optimization problem is solved as an Extended Multi‐objective Optimal Power Flow (EMOPF) problem using Lexico Graphic Method (LGM). Thereafter, using the concept of Fair Resource Allocation (FRA), the cost of reactive power is allocated to existing transactions. The application of the algorithm to a test system is also presented.

AbstractEarly detection of oral precancerous and malignant lesions is still a diagnostic challenge for most of clinicians, and ideal adjuncts for detection of these lesions are currently unavailable. Our preliminary study has indicated that rose bengal (RB) staining might have the potency as a diagnostic aid; however, its clinical significance and reliability in hospital‐based population are still not clear. In the present study, we investigated the efficacy of RB staining in detection of oral precancerous and malignant lesions. RB staining was conducted in 132 patients, and staining results were determined by a 4‐graded shade guide, which had been quantitatively measured in the 1976 CIEL*a*b* space by instrumental colorimetry. Histological examination was performed in 128 of 132 patients after RB staining. The sensitivity and specificity to detect epithelial dysplasia (DP) and oral squamous cell carcinoma were 93.9 and 73.7%, respectively. The positive and negative likelihood ratios were 3.570 and 0.082, respectively. Moreover, RB staining seemed promising to detect DP in oral leukoplakia, lichen planus and leukokeratosis. In this study, 5 of 6 DP or oral squamous cell carcinoma were identified by RB staining before histological examination. In conclusion, RB staining may be a valuable diagnostic test in detection of oral precancerous and malignant lesions. © 2007 Wiley‐Liss, Inc.
Analysis of chromosome 10 aberrations in rat endometrial cancer—evidence for a tumor suppressor locus distal to Tp53

Published: January 2007

AbstractWe have recently shown in the BDII rat model of human endometrial adenocarcinoma (EAC), rat chromosome 10 (RNO10) is frequently involved in chromosomal aberrations. In the present study, we investigated the association between RNO10 deletions, allelic imbalance (AI) at RNO10q24 and Tp53 mutation in 27 rat EAC tumors. We detected chromosomal breakage accompanied by loss of proximal and/or gain of distal parts of RNO10 in approximately 2/3 of the tumors. This finding is suggestive of a tumor suppressor activity encoded from the proximal RNO10. Given the fact that Tp53 is located at RNO10q24‐q25, we then performed Tp53 mutation analysis. However, we could not find a strong correlation between AI/deletions at RNO10q24 and Tp53 mutation. Instead, the observed patterns for AI, chromosomal breaks and deletions suggest that major selection was directed against a region located close to, but distal of Tp53. In different human malignancies a similar situation of AI at chromosome band 17p13.3 (HSA17p13.3) unassociated with TP53 mutation has been observed. Although RNO10 is largely homologous to HSA17, the conservation with respect to gene order among them is not extensive. We utilized publicly available draft DNA sequences to study intrachromosomal rearrangement during the divergence between HSA17 and RNO10. By using reciprocal comparison of rat and human genome data, we could substantially narrow down the candidate tumor suppressor region in rat from 3 Mb to a chromosomal segment of about 0.5 Mb in size. These results provide scientific groundwork for identification of the putative tumor suppressor gene(s) at 17p13.3 in human tumors. © 2006 Wiley‐Liss, Inc.
Characteristics of hydroxyapatite coated titanium porous coatings on Ti‐6Al‐4V substrates by plasma sprayed method
Authors: Yang C. Y. , Chen C. R. , Chang E. , Lee T. M. 
Published: January 2007

AbstractA porous metal coating applied to solid substrate implants has been shown, in vivo, to anchor implants by bone ingrowth. Calcium phosphate ceramics, in particular hydroxyapatite [Ca10(PO4)6(OH)2, HA], are bioactive ceramics, which are known to be biocompatible and osteoconductive, and these ceramics deposited on to porous‐coated devices may enhance bone ingrowth and implant fixation. In this study, bi‐feedstock of the titanium powder and composite (Na2CO3/HA) powder were simultaneously deposited on a Ti‐6Al‐4V substrate by a plasma sprayed method. At high temperature of plasma torch, the solid state of Na2CO3 would decompose to release CO2 gas and then eject the molten Ti powder to induce the interconnected pores in the coatings. After cleaning and soaking in deionized water, the residual Na2CO3 in the coating would dissolve to form the open pores, and the HA would exist at the surface of pores in the inner coatings. By varying the particle size of the composite powder, the porosity of porous coating could be varied from 25.0 to 34.0%, and the average pore size of the porous coating could be varied to range between 158.5 and 202.0 μm. Using a standard adhesive test (ASTM C‐633), the bonding strength of the coating is between 27.3 and 38.2 MPa. By SEM, the HA was observed at the surface of inner pore in the porous coating. These results suggest that the method exhibits the potential to manufacture the bioactive ceramics on to porous‐coated specimen to achieve bone ingrowth fixation for biomedical applications. © 2007 Wiley Periodicals, Inc.

Antigen‐specific immune complexes in urine of patients with lymphatic filariasis
Authors: Dixit Vandana , Subhadra A.V. , Bisen P.S. , Harinath B.C. , Prasad G.B.K.S. 
Published: January 2007

AbstractLymphatic filarial subjects with disease manifestations exhibit significantly elevated levels of immune complexes (ICs) in their circulation. The objective of the study was to explore the possible excretion of filaria‐specific soluble ICs in urine of subjects with lymphatic filariasis. Paired urine (overnight) and serum samples were analyzed for complement activating filarial antigen containing immune complexes by enzyme‐linked immunosorbent assay (ELISA). Antigen‐specific ICs were detected in urine samples of 34% of subjects with filarial disease manifestations while the frequency of occurrence was low in microfilaremic subjects. The titer of urine ICs is significantly high in subjects with chronic filariasis as compared to microfilaria (mf) carriers. The occurrence of filaria‐specific ICs in urine and their passage through the filtering structures of the kidney is suggestive of the focal or diffuse damage in those subjects. Detection of ICs in urine may provide a noninvasive means of assessing the extent of renal damage in patients with lymphatic filariasis. J. Clin. Lab. Anal. 21:46–48, 2007. © 2007 Wiley‐Liss, Inc.

AbstractAlthough Korea is a hepatitis B virus (HBV) endemic area, relatively few full‐length genome sequences are available. In particular, no comparative analysis has been performed on the full‐genome sequences of different HBV quasispecies from a single Korean patient. This report describes the full‐length sequences of five HBV clones (two clones with shorter PCR amplicons and three clones with longer amplicons). Large deletions, that is, 685‐bp, 487‐bp, and 144‐bp, that might interfere with the production of normal proteins were observed in four of five clones. Double mutations in the basal core promoter (BCP) region (T1762/A1764) were detected in two clones but no precore mutations (A1896) were detected in any of the five clones. These data support previous results that genotype C, in particular Korean clones of this genotype, is prone to mutations. Two independent mechanisms, namely, the deletions of long lengths and amino acid substitutions followed by BCP double mutations might contribute to the diversity of HBV quasispecies. Considering the importance of HBV quasispecies as HBV variant sources, the distribution of HBV quasispecies in mutation prone genotype C prevalent areas like Korea, should be monitored to improve the management of chronic HBV infections and to control HBV variants that arise due to the administration of vaccine or antiviral therapy.

Published: January 2007

AbstractThe production, secretion, and localization of surface proteins of hepatitis B virus (HBV) and the ratio of large to small surface protein S was studied in HepG2 cells transfected with the wild‐type and mutant pre‐S1 and pre‐S2/S promoters of HBV molecular clones 313.1 (GenBank accession no. AY161147) and 761.1 (GenBank accession no. AY161159) from two patients with occult HBV infection. Fusion constructs were made by in frame fusion of the wild‐type surface gene to the mutant pre‐S1 and pre‐S2/S promoters and wild‐type promoter so that the structural part of the small surface protein remains identical. HepG2 cells transfected transiently were used for analysis. HBV surface proteins production and secretion was determined by enzyme linked immuno assay (ELISA) and localization by immunofluorescence. Immunoprecipitation of the large, middle, and small surface protein was carried out in transient transfected and metabolically labeled cells to determine the ratio of the large to small surface protein. The results indicate that HepG2 cells transfected with mutant HBV promoters had reduced HBV surface proteins secretion compared to wild‐type HBV. HepG2 cells transfected with mutant HBV pre‐S1 and pre‐S2/S promoters showed cytoplasmic aggregation of HBV surface proteins compared to wild‐type HBV promoters, which showed diffuse cytoplasmic localization. In all cases, the HBV surface proteins localized to the endoplasmic reticulum. The ratio between the large and small surface protein was 1.89 and 0.56 with mutant HBV 313.1 and 761.1 pre‐S1 and pre‐S2/S promoters, respectively, compared to 0.17 in wild‐type. Thus, the aggregation of surface proteins, altered ratio and secretion of surface proteins were possibly the causes of occult hepatitis B infection. J. Med.

Published: January 2007

AbstractNegotiating to resolve conflicting objectives requires flexibility—the willingness and skill to change your approach to suit the situation at hand. The authors discuss five negotiating strategies and which to select based on the importance of the outcome and the relationship with the other person to you and your company. Adopting the best style— avoiding, accommodating, competing, collaborating, or compromising—for the situation may require overcoming your natural preference for one style as well as matching or mismatching the other person's preferred style.

On Impulse Distortion in Dispersive Media
Authors: Boese Fritz G. 
Published: January 2007

AbstractPulse distortion is due to nonlinear wave number functions of the frequency. For the case of smooth nonlinear wave numbers, a sequence of approximations to the propagation operator which carries the incident pulse to the distorted output pulse is set forth. When applied to the actual incident pulse, they allow the study of the development of the distortion with (a) increasing travel length in the propagation medium and (b) also with respect to the properties of the propagation medium. Of special interest are Gaussian incident pulses for which the distorted pulse form is more concisely representable. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Harmonical analysis of the total ponderomotive force
Authors: Langemann Dirk 
Published: January 2007

AbstractThe total ponderomotive force which moves for example rainwater droplets on outdoor high‐voltage insulators [1, 2], is given as a series of inhomogeneity indicators of the undisturbed electric field in the case of a round conductive and uncharged test body. The series expansion enables us to approximate the total ponderomotive force at an arbitrary position with a single numerical solution of the boundary‐value problem for the undisturbed electric potential in absence of any droplet.

AbstractThe direct applicability of SVD‐based methods in model reduction of large LTI systems is very limited. As a remedy we present a reduction framework based on the combination of hierarchical substructuring and SVD‐based methods. The substructuring approach is similar to the AMLS algorithm that has been successfully applied in very large eigenvalue computations. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Multidimensional Inverse Heat Conduction Calculations
Authors: Reinhardt Hans‐Jürgen , Frohne Jörg , Suttmeier Franz‐Theo , Hào Dinh Nho 
Published: January 2007

AbstractInverse Heat Conduction Problems (IHCPs) have been extensively studied over the last 50 years. They have numerous applications in many branches of science and technology. The problem consists in determining the temperature and heat flux at inaccessible parts of the boundary of a 2‐ or 3‐dimensional body from corresponding data – called ‘Cauchy data’ – from accessible parts of the boundary. It is well‐known that IHCPs are illposed which means that small perturbations in the data may cause large errors in the solution.In this contribution we give a short overview over our contributions to multidimensional IHCP's and indicate what computational results for which sort of problems we have obtained.

An Extended FE Formulation for Elasto‐Plastic Materials
Authors: Rempler Uwe , Ehlers Wolfgang , Wieners Christian 
Published: January 2007

AbstractWe present an alternative method for the numerical simulation of elasto‐plastic material behaviour. For this extended Finite Element (FE) formulation the history variables, which provide the information of plastic deformations from the previous timesteps, are represented as FE functions. This results in additional degrees of freedom (DOF), and the radial return of the standard formulation is replaced by a fully coupled Newton method for the extended system. Numerical studies, using viscoplastic regularization within a geometrically linear approach prove comparative results and an advantage in calculation time for the extended FE formulation.

Published: January 2007

AbstractWe consider optimal control problems for semilinear parabolic PDEs where process and measurement noise can occur. We discuss the solution of such problems by using a Model Predictive Control (MPC) strategy. For the resulting sub‐problems we will use a Linear Quadratic Gaussian (LQG) design. Thus we will discuss the efficient implementation of the LQG approach since it is the major computational part in the MPC scheme for this class of optimal control problems. We will present some numerical results for the Burgers equation. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
