Selected AbstractsThe Milled Bar-Retained Removable Bridge Implant-Supported Prosthesis: A Treatment Alternative for the Edentulous MaxillaJOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 4 2002DGDP(UK), PAUL A. TIPTON BDS ABSTRACT Restoration of the edentulous jaw with dental implants can be achieved using either an implant-supported prosthesis, such as a fixed bridge, or an implant-retained prosthesis, such as a traditional overdenture. The implant-retained prostheses use edentulous ridges as primary stress-bearing regions, and through stress-breaking mechanisms, the implants are not loaded during function. However, the success rates of maxillary overdentures do not appear to be as good as for mandibular overdentures; this may be attributable to the adverse loading conditions, short implant length, poor quality of bone, number of implants used, flexible bar design, or poor treatment planning. Many articles have also described the numerous problems and multiple visits required in maintaining a traditional bar-retained overdenture restoration, often making it more expensive in the long term than a fixed restoration. The milled bar implant-supported prosthesis offers the benefits of both fixed and removable restorations. Its infrastructure provides the same rigidity as the fixed restoration, owing to the precise fit to the superstructure, which is removable, to promote adequate access for hygiene, yet it still provides lip support and maintains close contact with the soft tissues. These advantages enhance phonetics, esthetics, correct lip support, maintenance, and patient comfort. CLINICAL SIGNIFICANCE Restoring esthetics and function for the edentulous patient requires a multidiscipline approach for success. This article discusses the techniques for restoring function and esthetics for these patients, using a milled bar restoration supported and retained by dental implants. [source] Types of article published in physiotherapy journals: a quantitative analysisPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 4 2009Matteo Paci Abstract Background and Purpose.,The aim of this study was to quantify and assess the types of research and review articles published in physiotherapy professional journals with international circulations.,Method.,Selected articles from nine physiotherapy journals in a period of five years were classified according to their study design.,Results.,A total number of 1627 articles were included in this study of which 205 (12.60%) were randomized controlled trial (RCT). Articles published with the highest frequency were ,observational/descriptive studies' (n = 305, 18.75%), whereas ,meta-analyses' were the rarest ones (n = 21, 1.29%). Many articles were validation studies (n = 216, 13.28%) and articles classified as ,others' (n = 217, 13.34%). High heterogeneity was found in terms of distribution over years and journals with an improvement of the number of RCTs among years.,Conclusion.,The distribution of different types of article in physiotherapy journals is similar to other disciplines. The improvement of RCTs represents an important move in the right direction for evidence-based physiotherapy research. Copyright © 2009 John Wiley & Sons, Ltd. [source] Launch Decisions and New Product Success: An Empirical Comparison of Consumer and Industrial ProductsTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 1 2000Erik Jan Hultink Many articles have investigated new product development success and failure. However, most of them have used the vantage point of characteristics of the product and development process in this research. In this article we extend this extensive stream of research, looking at factors affecting success; however, we look at the product in the context of the launch support program. We empirically answer the question of whether successful launch decisions differ for consumer and industrial products and identify how they differ. From data collected on over 1,000 product introductions, we first contrast consumer product launches with industrial product launches to identify key differences and similarities in launch decisions between market types. For consumer products, strategic launch decisions appear more defensive in nature, as they focus on defending current market positions. Industrial product strategic launch decisions seem more offensive, using technology and innovation to push the firm to operate outside their current realm of operations and move into new markets. The tactical marketing mix launch decisions (product, place, promotion and price) also differ markedly across the products launched for the two market types. Successful products were contrasted with failed products to identify those launch decisions that discriminate between both outcomes. Here the differences are more of degree rather than principle. Some launch decisions were associated with success for consumer and industrial products alike. Launch successes are more likely to be broader assortments of more innovative product improvements that are advertised with print advertising, independent of market. Other launch decisions uniquely related to success per product type, especially at the marketing mix level (pricing, distribution, and promotion in particular). The launch decisions most frequently made by firms are not well aligned with factors associated with higher success. Additionally, comparing the decisions associated with success to the recommendations for launches from the normative literature suggests that a number of conventional heuristics about how to launch products of each type will actually lead to failure rather than success. [source] The all-ceramic, inlay supported fixed partial denture.AUSTRALIAN DENTAL JOURNAL, Issue 2 2010Part 1. Abstract The effect of cavity design is a controversial and underrated factor in the clinical success of ceramic inlays and inlay supported prosthesis. Many articles and studies have been conducted into the advantages and disadvantages of isolated aspects of preparation design, but lacking is a review of the most relevant papers which bring together a consensus on all the critical features. Hence, a review and analysis of cavity depth, width, preparation taper and internal line angles is warranted in our attempts to formulate preparation guidelines that will lead to clinically successful, all-ceramic inlay restorations and ceramic inlay supported prosthesis. [source] Epidemiology of Helicobacter pylori infectionHELICOBACTER, Issue 2003Hoda M. Malaty ABSTRACT Transmission of the infection revealed in many articles an important role of the mothers in transmitting the infection to their children. The epidemiology and risk factors of Helicobacter pylori infection were examined. The seroprevalence of the infection in different populations as well as colonization of the infection in childhood was reported. Moreover, this year attention was aimed at examining the associations between Helicobacter pylori with gastrointestinal and nongastrointestinal diseases. [source] Novel tools for extraction and validation of disease-related mutations applied to fabry disease,HUMAN MUTATION, Issue 9 2010Remko Kuipers Abstract Genetic disorders are often caused by nonsynonymous nucleotide changes in one or more genes associated with the disease. Specific amino acid changes, however, can lead to large variability of phenotypic expression. For many genetic disorders this results in an increasing amount of publications describing phenotype-associated mutations in disorder-related genes. Keeping up with this stream of publications is essential for molecular diagnostics and translational research purposes but often impossible due to time constraints: there are simply too many articles to read. To help solve this problem, we have created Mutator, an automated method to extract mutations from full-text articles. Extracted mutations are crossreferenced to sequence data and a scoring method is applied to distinguish false-positives. To analyze stored and new mutation data for their (potential) effect we have developed Validator, a Web-based tool specifically designed for DNA diagnostics. Fabry disease, a monogenetic gene disorder of the GLA gene, was used as a test case. A structure-based sequence alignment of the alpha-amylase superfamily was used to validate results. We have compared our data with existing Fabry mutation data sets obtained from the HGMD and Swiss-Prot databases. Compared to these data sets, Mutator extracted 30% additional mutations from the literature. Hum Mutat 31:1026,1032, 2010. © 2010 Wiley-Liss, Inc. [source] The female partner's satisfaction with sildenafil citrate treatment of erectile dysfunctionINTERNATIONAL JOURNAL OF UROLOGY, Issue 9 2004TAKAHARU ICHIKAWA Abstract Background: Data on female partners' satisfaction are scarce, although there have been many articles on patient satisfaction after sildenafil citrate treatment. The aim of this study was to evaluate the satisfaction of female partners of patients receiving sildenafil citrate for their erectile dysfunction (ED) and to assess the female partners' sexual function. Methods: Ninety-eight patients with ED were treated. Their female partners were asked to answer a questionnaire we have prepared to evaluate the efficacy of treatment, sexual satisfaction and changes in quality of life. It also included a question about female sexual function. From the results, the relationship between their female partner's satisfaction and efficacy of treatment, as well as female sexual function, were assessed. Results: Thirty (31%) questionnaires were returned to us for analysis. Effectiveness of the treatment was acknowledged by 90% of the partners. An improvement in their partner's quality of life was noticed by 60% of the women. The majority (66.7%) of the female partners were satisfied with sildenafil citrate treatment and 20% were disappointed. Moreover, 20% of the female partners were concerned about adverse events. Regarding female sexual function, some form of sexual dysfunction affected 46.7% of the women. Furthermore, a significant number (P = 0.0230) of the female partners disappointed with the treatment had some kind of sexual dysfunction. Conclusions: The results indicated that female partners reported relatively high levels of treatment satisfaction. Female partners' sexual function and anxiety regarding adverse events should be evaluated when their satisfaction with sildenafil citrate treatment is poor despite an improvement of erectile function. [source] Multivariate methods in pharmaceutical applicationsJOURNAL OF CHEMOMETRICS, Issue 3 2002Jon Gabrielsson Abstract This review covers material published within the field of pharmacy in the last five years. Articles concerning experimental design, optimization and applications of multivariate techniques have been published, from factorial designs to multivariate data analysis, and the combination of the two in multivariate design. The number of publications on this topic testifies to the good results obtained in the studies. Much of the published material highlights the usefulness of experimental design, with many articles dealing with optimization, where much effort is spent on getting useful results. Examples of multivariate data analysis are comparatively few, but these methods are gaining in use. The employment of multivariate techniques in different applications has been reviewed. The examples in this review represent just a few of the possible applications with different aims within pharmaceutical applications. A number of companies are using experimental design as a standard tool in preformulation and in combination with response surface modeling. The properties of e.g. a tablet can be optimized to fulfill a well-specified aim such as a specific release profile, hardness, disintegration time etc. However, none of the companies apply multivariate methods in all steps of the drug development process. As this is still very much a growing field, it is only a question of time before experimental design, optimization and multivariate data analysis are implemented throughout the entire formulation process, from performulation to multivariate process control. Copyright ©,2002 John Wiley & Sons, Ltd. [source] Searching for the Intervention in Intervention Research ReportsJOURNAL OF NURSING SCHOLARSHIP, Issue 1 2008Vicki S. Conn Purpose: Precisely described interventions in nursing research reports are essential as a foundation for nursing practice and to facilitate future research. The purpose of this project was to characterize the intervention descriptions in nursing intervention research reports. Design and Methods: Quantitative content analysis was used to analyze intervention descriptions in reports published in English-language general nursing journals during 2005. Normative analysis was used to examine reports for details related to intervention content and delivery. Physical unit analysis was used to compare relative amounts of article space devoted to intervention description vs. other methodological details. Findings: Results were tabulated for 141 research articles published in 27 journals. Analysis indicated incomplete reporting of intervention details in many articles. Dose and dosing frequency were rarely completely defined. Delivery setting and interventionist were frequently not indicated, and the professional credentials of nurse interventionists were often unclear. While descriptions of interventions involving substances or devices were typically detailed, the specifics of psychological, educational, behavioral, and systems-level interventions were often lacking. Intervention descriptions averaged 7.27% of total article space, whereas nonintervention methodological descriptions averaged 20.74% of space. Of studies examined, only 38 (27.0%) reported enough detail to potentially replicate the study or translate the intervention into practice. Conclusions: Intervention descriptions in general nursing journals lack sufficient detail to provide the evidence basis for practice. [source] Modernization of Tax Administrations and Optimal Fiscal PoliciesJOURNAL OF PUBLIC ECONOMIC THEORY, Issue 6 2009MARTIN BESFAMILLE Since Sandmo (1981), many articles have analyzed optimal fiscal policies in economies with tax evasion. All share a feature: they assume that the cost of enforcing the tax law is exogenous. However, governments often invest resources to reduce these enforcement costs. In a very simple model, we incorporate such investments in the analysis of an optimal fiscal policy. We characterize their optimal level and we show numerically how they interact with the other dimensions of the optimal fiscal policy. Finally, we highlight the differences between our results and those obtained in a model without investment in the tax administration. [source] A review with comprehensive data on experimental indirect scalar NMR spin,spin coupling constants across hydrogen bondsMAGNETIC RESONANCE IN CHEMISTRY, Issue 7 2008Ibon Alkorta Abstract Scalar NMR spin,spin coupling constants across hydrogen bonds are fundamental in structural studies and as test grounds for theoretical calculations. Since they are scattered among many articles of different kinds, it seems useful to collect them in the most comprehensive way. Copyright © 2008 John Wiley & Sons, Ltd. [source] From the diffusion coefficient to the diffusion tensorNMR IN BIOMEDICINE, Issue 7-8 2002Denis Le Bihan Abstract With diffusion tensor MRI one has access to the organization in space of tissue microstructural components. This outstanding potential adds, however, another layer of complexity to the diffusion MRI data acquisition and analysis processes. Over the last few years many articles have been published dealing with those matters. This special issue is thus timely to provide readers with the synthesis and the overall viewpoints from leading contributors to the field. Copyright © 2002 John Wiley & Sons, Ltd. [source] The two peaks G, band in carbon nanotubesPHYSICA STATUS SOLIDI (B) BASIC SOLID STATE PHYSICS, Issue 10 2008Indhira O. Maciel Abstract In this work we discuss the nature of the extra peak that appears in the low frequency side the G, band in the Raman spectra of single wall and double wall carbon nanotubes. This peak has been reported in many articles assigned as either the G, band from small diameter nanotubes or the response for fulfilment of resonance conditions with incident and scattered light. Here we show that this peak is present in the Raman spectra independently on the diameter distribution of the sample and disappears after heat treatment. We believe the lower frequency component of the two-peaks G, band in carbon nanotubes is related to the presence of defects in the carbon nanotube structure. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source] The course and branching pattern of pudendal nerve in fetusCLINICAL ANATOMY, Issue 7 2008Necdet Kocabiyik Abstract The pudendal nerve is a considerably large branch of the sacral plexus. There are many articles in the literature concerning the pudendal nerve in adults, but as far as we know, there is none on the branching pattern and variations in pudendal nerve anatomy in fetus. This study investigates the pudendal nerve trunking with respect to the piriformis muscle in 25 formalin-fixed fetuses (50 sides of pelves, 15 females, 10 males), ranging from 20 to 37 weeks of gestation. We investigate pudendal nerve trunking in four types: Type I-a is defined as single-trunk with the inferior rectal nerve branching proximal to the dorsal nerve of penis/clitoris (38%), Type I-b is also single-trunk with the dorsal nerve of penis/clitoris branching proximal to the inferior rectal nerve (24%), Type II is double-trunk with medial trunk as an inferior rectal nerve (34%), and Type III is triple-trunk (4%). We measured the average diameter of the main trunk of pudendal nerve in Type I-a and I-b groups to be 0.98 ± 0.33 mm. We also measured the average length of the pudendal nerve trunks before the dorsal nerve of penis/clitoris branch to be 7.35 ± 3.50 mm. There was no significant statistical difference in the average length, diameter, number of trunks, and pudendal nerve variations between male and female and also right and left sides of the pelves. This first and detailed fetal study of pudendal nerve trunking with respect to the piriformis muscle would be useful for educational anatomy dissections and anatomical landmark definitions for relevant clinical procedures.
