Authors: Mizukoshi Yoshiteru , Masahashi Naoya 
Published: May 2012

Abstract
Titanium alloy Ti–6Al–4V was galvanostatically anodized in an aqueous acetic acid electrolyte followed by annealing to form anatase-structured TiO2. The formed pale yellowish oxide contained Al3+, V5+, and V4+ in the topmost surface of the anodized oxide. The anodized TiO2 photocatalytically decomposed acetaldehyde under visible light illumination (&gt;400 nm).
New Synthetic Opportunities in Miniaturized Flow Reactors with Inductive Heating
Authors: Kirschning Andreas , Kupracz Lukas , Hartwig Jan 
Published: May 2012

Abstract
Inductive heating has emerged as a new heating technique in the laboratory, particularly when combined with miniaturized flow reactor devices. Traditionally, inductive heating is found in industrial applications like the heating of large metallic objects such as in the bending of pipes, bonding and welding. New fields of application are the preparation of nanotubes as well as hyperthermia in the treatment of cancer. This account specifically addresses the use of heatable materials such as superparamagnetic iron oxide nanoparticles in many areas of organic synthesis and how this enabling technology compares to conventional as well as microwave heating.

Authors: Yamaguchi Kazuya , Wang Ye , Kobayashi Hiroaki , Mizuno Noritaka 
Published: May 2012

Abstract
Hydration of various kinds of nitriles could efficiently be promoted by amorphous MnO2 using reduced amounts of water (2 equiv or less), giving the corresponding primary amides in moderate to high yields. The observed catalysis was truly heterogeneous, and the retrieved MnO2 could be reused without an appreciable loss of its high catalytic performance.

Published: May 2012

Abstract
A simple and efficient procedure for the synthesis of unsymmetrical diaryl selenides has been developed by magnetically separable CuFe2O4 nanoparticle catalyzed reactions of organoboranes with PhSeBr in recyclable PEG-400 medium at 80 °C and Cs2CO3 as base. Using this protocol, a variety of unsymmetrical selenides were obtained in good to excellent yields. The copper ferrite nanoparticles were magnetically separated, recycled, and reused up to four cycles.
Calcium Phosphate Mineralization Induced by Synthetic Peptides Having Different Distributions in Simulated Body Fluids
Authors: Hashizume Mineo , Kamaya Noriaki , Uchida Yuki , Matsubara Teruhiko , Sato Toshinori 
Published: May 2012

Abstract
Synthetic peptides having hydroxyapatite binding ability can induce calcium phosphate (CaP) mineralization in simulated body fluids. The peptides freely dispersed in the solution induce formation of peptide–CaP hybrids having sheet-like morphologies, whereas immobilized on solid substrates they induce hydroxyapatite deposition on the substrate surfaces. The results clearly show that distribution of the peptides affects their mineralization properties.
Sol–Gel-derived Bridged Polysilsesquioxane as a Hydrogen Peroxide Decomposition Catalyst: Immobilization of a Dimanganese Complex and Its Improved Thermal Stability
Authors: Saito Hitomi , Ishisone Akira , Horikawa Yuhei , Ishiyama Takeshi , Higashimura Hideyuki , Sugahara Yoshiyuki 
Published: May 2012

Abstract
Bridged polysilsesquioxane possessing dimanganese complex moiety, a model complex for catalase, exhibited catalytic activity for the hydrogen peroxide decomposition reaction without any deactivation. The catalytic activity was mostly retained, even after 24-h acid treatment at 80 °C, improving thermal stability after immobilization.
Balance is an important predictive factor for quality of life and function after primary total knee replacement
Authors: Schwartz I. , Kandel L. , Sajina A. , Litinezki D. , Herman A. , Mattan Y. 
Published: May 2012

We investigated the extent to which improved balance relative to pain relief correlates with the success of total knee replacement (TKR). A total of 81 patients were recruited to the study: 16 men (19.8%) and 65 women (80.2%). Of these, 62 patients (10 men, 52 women) with a mean age of 73 (57 to 83) underwent static and dynamic assessment of balance pre-operatively and one year post-operatively. The parameters of balance were quantified using commercially available and validated equipment. Motor function and self-reported outcome were also assessed.There was a significant improvement in dynamic balance (p < 0.001) one year after TKR, and better balance correlated with improved mobility, functional balance and increased health-related quality of life. As it seems that balance, and not only pain relief, influences the success of TKR, balance skills should be better addressed during the post-operative rehabilitation of patients who undergo TKR.
Arthroscopic reduction of the dislocated hip in infants
Authors: Eberhardt O. , Fernandez F. F. , Wirth T. 
Published: May 2012

We present our early experience of arthroscopic reduction of the dislocated hip in very young infants with developmental dysplasia of the hip (DDH). Eight dislocated hips, which had failed attempts at closed reduction, were treated by arthroscopy of the hip in five children with a mean age of 5.8 months (4 to 7). A two-portal technique was used, with a medial sub-adductor portal for a 2.7 mm cannulated system with a 70° arthroscope and an anterolateral portal for the instruments. Following evaluation of the key intra-articular structures, the hypertrophic ligamentum teres and acetabular pulvinar were resected, and a limited release of the capsule was performed prior to reduction of the hip. All hips were reduced by a single arthroscopic procedure, the reduction being confirmed on MRI scan. None of the hips had an inverted labrum. The greatest obstacle to reduction was a constriction of the capsule. At a mean follow-up of 13.2 months (9 to 24), all eight hips remained stable. Three developed avascular necrosis. The mean acetabular index decreased from 35.5° (30° to 40°) pre-operatively to 23.3° (17° to 28°). This study demonstrates that arthroscopic reduction is feasible using two standardised portals. Longer follow-up studies are necessary to evaluate the functional results.

Published: May 2012

The Bologna–Oxford (BOX) total ankle replacement (TAR) was developed with the aim of achieving satisfactory pain-free movement of the ankle. To date, only one single multicentre study has reported its clinical results. The aim of this study was to conduct an independent review of its mid-term results. We retrospectively reviewed a total of 60 prospectively followed patients in whom 62 BOX TARs had been implanted between 2004 and 2008. We used the American Orthopedic Foot and Ankle Society (AOFAS) score to assess the clinical results. Standardised radiographs taken at the time of final follow-up were analysed by two observers. The overall survival was 91.9% at a mean follow-up of 42.5 months (24 to 71). The mean AOFAS score had improved from 35.1 points (sd 16.6; 4 to 73) pre-operatively to 78.0 (sd 10.7; 57 to 100) at final follow-up (p < 0.01). Tibial radiolucencies < 2 mm in width were seen around 16 TARs. Talar radiolucencies < 2 mm were seen around four TARs. A total of 47 patients (78.3%) were very satisfied or satisfied with the outcome. Five patients required revision for functional limitation or continuing pain.

Published: May 2012

Peri-articular soft-tissue masses or ‘pseudotumours’ can occur after large-diameter metal-on-metal (MoM) resurfacing of the hip and conventional total hip replacement (THR). Our aim was to assess the incidence of pseudotumour formation and to identify risk factors for their formation in a prospective cohort study. A total of 119 patients who underwent 120 MoM THRs with large-diameter femoral heads between January 2005 and November 2007 were included in the study. Outcome scores, serum metal ion levels, radiographs and CT scans were obtained. Patients with symptoms or an identified pseudotumour were offered MRI and an ultrasound-guided biopsy. There were 108 patients (109 hips) eligible for evaluation by CT scan at a mean follow-up of 3.6 years (2.5 to 4.5); 42 patients (39%) were diagnosed with a pseudotumour. The hips of 13 patients (12%) were revised to a polyethylene acetabular component with small-diameter metal head. Patients with elevated serum metal ion levels had a four times increased risk of developing a pseudotumour. This study shows a substantially higher incidence of pseudotumour formation and subsequent revisions in patients with MoM THRs than previously reported. Because most revision cases were identified only after an intensive screening protocol, we recommend close monitoring of patients with MoM THR.
Factors affecting outcome of massive intercalary bone allografts in the treatment of tumours of the femur
Authors: Frisoni T. , Cevolani L. , Giorgini A. , Dozza B. , Donati D. M. 
Published: May 2012

We retrospectively reviewed 101 consecutive patients with 114 femoral tumours treated by massive bone allograft at our institution between 1986 and 2005. There were 49 females and 52 males with a mean age of 20 years (4 to 74). At a median follow-up of 9.3 years (2 to 19.8), 36 reconstructions (31.5%) had failed. The allograft itself failed in 27 reconstructions (24%). Mechanical complications such as delayed union, fracture and failure of fixation were studied. The most adverse factor on the outcome was the use of intramedullary nails, followed by post-operative chemotherapy, resection length > 17 cm and age > 18 years at the time of intervention. The simultaneous use of a vascularised fibular graft to protect the allograft from mechanical complications improved the outcome, but the use of intramedullary cementing was not as successful. In order to improve the strength of the reconstruction and to advance the biology of host–graft integration, we suggest avoiding the use of intramedullary nails and titanium plates, but instead using stainless steel plates, as these gave better results. The use of a supplementary vascularised fibular graft should be strongly considered in adult patients with resection > 17 cm and in those who require post-operative chemotherapy.
Do we need a gender-specific total knee replacement?
Authors: Thomsen M. G. , Husted H. , Bencke J. , Curtis D. , Holm G. , Troelsen A. 
Published: May 2012

The purpose of this study was to investigate whether a gender-specific high-flexion posterior-stabilised (PS) total knee replacement (TKR) would offer advantages over a high-flex PS TKR regarding range of movement (ROM), ‘feel’ of the knee, pain and satisfaction, as well as during activity. A total of 24 female patients with bilateral osteoarthritis entered this prospective, blind randomised trial in which they received a high-flex PS TKR in one knee and a gender-specific high-flexion PS TKR in the other knee. At follow-up, patients were assessed clinically measuring ROM, and questioned about pain, satisfaction and daily ‘feel’ of each knee. Patients underwent gait analysis pre-operatively and at one year, which yielded kinematic, kinetic and temporospatial parameters indicative of knee function during gait. At final follow-up we found no statistically significant differences in ROM (p = 0.82). The median pain score was 0 (0 to 8) in both groups (p = 0.95). The median satisfaction score was 9 (4 to 10) in the high-flex group and 8 (0 to 10) in the gender-specific group (p = 0.98). The median ‘feel’ score was 9 (3 to 10) in the high-flex group and 8 (0 to 10) in the gender-specific group (p = 0.66). Gait analysis showed no statistically significant differences between the two prosthetic designs in any kinematic, kinetic or temporospatial parameters. Both designs produced good clinical results with significant improvements in several gait parameters without evidence of any advantage in the gender-specific design.
Independent predictors of revision following metal-on-metal hip resurfacing

Published: May 2012

Modern metal-on-metal hip resurfacing has been widely performed in the United Kingdom for over a decade. However, the literature reports conflicting views of the benefits: excellent medium- to long-term results with some brands in specific subgroups, but high failure rates and local soft-tissue reactions in others. The National Joint Registry for England and Wales (NJR) has collected data on all hip resurfacings performed since 2003. This retrospective cohort study recorded survival time to revision from a resurfacing procedure, exploring risk factors independently associated with failure. All patients with a primary diagnosis of osteoarthritis who underwent resurfacing between 2003 and 2010 were included in the analyses. Cox’s proportional hazard models were used to analyse the extent to which the risk of revision was related to patient, surgeon and implant covariates. A total of 27 971 hip resurfacings were performed during the study period, of which 1003 (3.59%) underwent revision surgery. In the final adjusted model, we found that women were at greater risk of revision than men (hazard ratio (HR) = 1.30, p = 0.007), but the risk of revision was independent of age. Of the implant-specific predictors, five brands had a significantly greater risk of revision than the Birmingham Hip Resurfacing (BHR) (ASR: HR = 2.82, p < 0.001, Conserve: HR = 2.03, p < 0.001, Cormet: HR = 1.43, p = 0.001, Durom: HR = 1.67, p < 0.001, Recap: HR = 1.58, p = 0.007). Smaller femoral head components were also significantly more likely to require revision (≤ 44 mm: HR = 2.14, p < 0.001, 45 to 47 mm: HR = 1.48, p = 0.001) than medium or large heads, as were operations performed by low-volume surgeons (HR = 1.36, p < 0.001). Once these influences had been removed, in 4873 male patients < 60 years old undergoing resurfacing with a BHR, the five-year estimated risk of revision was 1.59%. In summary, after adjustment for a range of covariates we found that there were significant differences in the rate of failure between brands and component sizes. Younger male patients had good five-year implant survival when the BHR was used.
A Patent System with a Contingent Delegation Fee under Asymmetric Information
Authors: Kim Weonseek , Koo Bonwoo 
Published: May 2012

Abstract
Under the framework of a two-stage innovation process in which the first-stage innovation is commercialized by multiple firms at the second stage, this study proposes an optimal patent system for efficient commercialization by a lower cost firm when the R&D costs are private information. Under the existing patent system of granting patents sequentially to successful innovators, the commercialization can be achieved by an inefficient firm (called control loss) and duplicative R&D efforts may occur through competitive innovation race. This study shows that the problems of control loss and duplicative R&D efforts can be prevented if the patent office grants a patent with a mandatory contingent delegation fee only to the first innovator. A carefully designed contingent fee function can induce the first innovator to internalize the patent office’s objective function, leading to efficient commercialization by a lower cost firm.
Technology for Transparency: The Case of the Web‐Based Dutch National Health Portal
Authors: Ossebaard Hans C. , van Gemert‐Pijnen Lisette , Seydel Erwin R. 
Published: May 2012

AbstractAgainst a backdrop of New Public Management and healthcare system reform the Dutch Ministry of Health commissioned the National Institute for Public Health and the Environment (RIVM) to develop, host and manage an online public national health and care portal. The portal aims to facilitate consumer decision‐making behavior in health and healthcare and to contribute to transparency in order to improve the quality of care and the general functioning of the health markets. This article describes the policy context and uses a multi‐methods approach to evaluate the extent to which the portal, as an instrument of health policy, is meeting its original objectives. Four qualitative and quantitative methods of user data collection ‐ online survey, market monitoring, web analytics, and direct user feedback ‐ are used to estimate the impact of the portal with regard to user behavior and online health information needs over time. We find that the portal reaches a fair share of the Dutch health information market in quantitative and qualitative terms. However, while its exact contribution to the functioning of the health markets in terms of transparency remains undecided, it seems plausible that the portal's impact on choice behavior, choice awareness and empowerment is rather small.
Patient Trust in Internet‐based Health Records: An Analysis Across Operator Types and Levels of Patient Involvement in Germany
Authors: Rauer Ulrike 
Published: May 2012

AbstractPatient trust is often considered a major hurdle to the adoption of Internet‐based health records. Moreover, trust in physicians may suffer if patients do not trust the way their medical data is stored. This research examines the structural and institutional factors influencing patient trust in Internet‐based health records in Germany. Specifically, it focuses on the question of whether patient trust varies with the Internet‐based health record's operator type (medical vs. non‐medical, private vs. public) and the level of patient involvement in terms of access and control. To answer this question, a sequential mixed methods study was conducted. Eight semi‐structured patient interviews helped to gain understanding of trust and develop the survey instrument. Afterwards, the offline survey of 340 patients in four German surgeries enabled the findings to be generalised to the German population. The findings indicate that patients consider medical operators more trustworthy than non‐medical ones. However, the dichotomy between public and private is false: patients perceive physicians and health insurance providers as trustworthy, as opposed to the government and corporations. Likewise, patient involvement in terms of access and control is trust‐enhancing. But to accept a generally less trustworthy operator, control is necessary, as opposed to only access. These results provide valuable insights for policy measures regarding Internet‐based health records in Germany: to gain patient trust, the operator should ideally be of a medical nature and allow patients to get involved in how their health records are maintained.
“Spectral implies Tiling” for three intervals revisited
Authors: Bose Debashish , Madan Shobha 
Published: May 2012

Abstract.
Bose, Anil Kumar, Krishnan and Madan (2010)
showed that “Tiling implies Spectral” holds
for a union of three intervals and the reverse implication was
studied under certain restrictive hypotheses on the associated
spectrum. In this paper, we reinvestigate the “Spectral implies
Tiling” part of Fuglede's conjecture for the three interval case.
We first show that the “Spectral implies Tiling” for two intervals
follows from the simple fact that two distinct circles have at most
two points of intersections. We then attempt this for the case of
three intervals and except for one situation are able to prove
“Spectral implies Tiling”. Finally, for the exceptional case, we
show a connection to a problem of generalized Vandermonde
varieties.
An embodied semantic processing effect on eye gaze during sentence reading
Authors: Phillips Catherine I. , Sears Christopher R. , Pexman Penny M. 
Published: May 2012

AbstractThe present research examines the effects of body-object interaction (BOI) on eye gaze behaviour in a reading task. BOI measures perceptions of the ease with which a human body can physically interact with a word's referent. A set of high BOI words (e.g. cat) and a set of low BOI words (e.g. sun) were selected, matched on imageability and concreteness (as well as other lexical and semantic variables). Facilitatory BOI effects were observed: gaze durations and total fixation durations were shorter for high BOI words, and participants made fewer regressions to high BOI words. The results provide evidence of a BOI effect on non-manual responses and in a situation that taps normal reading processes. We discuss how the results (a) suggest that stored motor information (as measured by BOI ratings) is relevant to lexical semantics, and (b) are consistent with an embodied view of cognition (Wilson 2002).
Internationale Wirtschafts- und Unternehmensbeziehungen nach 1945
Authors: Kleinschmidt Christian 
Published: May 2012

Abstract
The traditional Theory of International Economic Relations concentrates on issues like balance of payments, exchange rates, comparative price advantages, international competition and production sites, thereby neglecting political and cultural aspects like the role of the state, information and communication, path dependencies or behavioural pattern. The following contributions try to incorporate these aspects in different ways, regarding three focal points in historical perspective: case studies of bilateral and multilateral economic and business relations after 1945, the influence of interest groups and cartels within the EEC, and the impact of crisis and globalisation on entrepreneurial attitudes and activities.
A Dutch Multinational’s Miracle in Post-war Germany
Authors: Wubs Ben 
Published: May 2012

Abstract
At the end of the 1960s a statistical survey run by the Bundesbank, revealed that the Netherlands was the second largest foreign direct investor in the Federal Republic of Germany (FRG). Only the American multinationals, which had become the world’s most important foreign direct investors after the war, had invested more in the FRG at that time. However, Dutch multinational investments in Germany had a long history and developed largely before the Second World War, often against the odds. At the end of the 1930s Dutch investments had been even larger than the investments of all American multinationals in Germany combined. Directly after the war all Dutch assets were put under Allied control, however despite this the big Dutch multinationals - Unilever, Royal Dutch Shell, Philips, and AKU – were able to regain control over their investments at the end of the 1940s. From this point onwards they continued to further expand their interests in the neighbouring country. This paper addresses the question of how and why the major Dutch multinationals were able to regain their property, and then grow so luxuriantly in the FRG. It shows that historical continuities and path dependence played a key role in this, alongside favourable market conditions after the war. The outcome, however, was uncertain and depended partly on extensive lobby activities.
