Authors: Sansone Valerio , Applefield Rachel C. , De Luca Paola , Pecoraro Valentina , Gianola Silvia , Pascale Walter , Pascale Valerio 
Published: December 2019

Aims The aim of this study was to systematically review the literature for evidence of the effect of a high-fat diet (HFD) on the onset or progression of osteoarthritis (OA) in mice. Methods A literature search was performed in PubMed, Embase, Web of Science, and Scopus to find all studies on mice investigating the effects of HFD or Western-type diet on OA when compared with a control diet (CD). The primary outcome was the determination of cartilage loss and alteration. Secondary outcomes regarding local and systemic levels of proteins involved in inflammatory processes or cartilage metabolism were also examined when reported. Results In total, 14 publications met our inclusion criteria and were included in our review. Our meta-analysis showed that, when measured by the modified Mankin Histological-Histochemical Grading System, there was a significantly higher rate of OA in mice fed a HFD than in mice on a CD (standardized mean difference (SMD) 1.27, 95% confidence interval (CI) 0.63 to 1.91). Using the Osteoarthritis Research Society International (OARSI) score, there was a trend towards HFD causing OA (SMD 0.78, 95% CI -0.04 to 1.61). In terms of OA progression, a HFD consistently worsened the progression of surgically induced OA when compared with a CD. Finally, numerous inflammatory cytokines such as tumour necrosis factor alpha (TNF-α), interleukin (IL)-1β, and leptin, among others, were found to be altered by a HFD. Conclusion A HFD seems to induce or exacerbate the progression of OA in mice. The metabolic changes and systemic inflammation brought about by a HFD appear to be key players in the onset and progression of OA. Cite this article: Bone Joint Res 2019;8:582–592.

Published: December 2019

Aims Commonly performed unicompartmental knee arthroplasty (UKA) is not designed for the lateral compartment. Additionally, the anatomical medial and lateral tibial plateaus have asymmetrical geometries, with a slightly dished medial plateau and a convex lateral plateau. Therefore, this study aims to investigate the native knee kinematics with respect to the tibial insert design corresponding to the lateral femoral component. Methods Subject-specific finite element models were developed with tibiofemoral (TF) and patellofemoral joints for one female and four male subjects. Three different TF conformity designs were applied. Flat, convex, and conforming tibial insert designs were applied to the identical femoral component. A deep knee bend was considered as the loading condition, and the kinematic preservation in the native knee was investigated. Results The convex design, the femoral rollback, and internal rotation were similar to those of the native knee. However, the conforming design showed a significantly decreased femoral rollback and internal rotation compared with that of the native knee (p < 0.05). The flat design showed a significant difference in the femoral rollback; however, there was no difference in the tibial internal rotation compared with that of the native knee. Conclusion The geometry of the surface of the lateral tibial plateau determined the ability to restore the rotational kinematics of the native knee. Surgeons and implant designers should consider the geometry of the anatomical lateral tibial plateau as an important factor in the restoration of native knee kinematics after lateral UKA.

In situ synthesis of silver nanoparticles on periodic supports as highly active and flexible surface-enhanced Raman spectroscopy substrates
Authors: Zhang Jiajie , Wang Chaonan , Wang Meng , Xu Tian 
Published: December 2019

With regard to surface-enhanced Raman spectroscopy (SERS), the preparation of substrates with high homogeneity and low cost remains a challenge. In this paper, cheap commercial DVD-R plates were adopted as supports, whose 3D periodic structure was transferred onto the surface of flexible polydimethylsiloxane (PDMS) easily. Then, silver nanoparticles were grown both on DVD and PDMS substrates by the in situ reduction method, and the SERS performances of these two substrates were investigated. The results confirmed that the PDMS-based substrate exhibited better enhancement performance and higher uniformity (

). In addition, due to the flexibility and transparency of PDMS, it is not restricted by the surface shape of the object when applied in in situ detection. This low-cost, simple method will be widely used in the in situ detection of surfaces of objects of any shape.

Authors: Belhassen Jeremy , Frisch Amos , Kapellner Yuval , Zalevsky Zeev , Karsenty Avi 
Published: December 2019

In this paper, we present the design of a silicon optoelectronic device
capable of speeding up processing capabilities. The data in this
device are electronic, while the modulation control is optical. It can
be used as a building block for the development of optical data
processing by silicon-based processors based on typical
microelectronics manufacturing processes. A V-groove-based structure
fabricated as part of the device allows obtaining enhanced
sensitivity to the polarization of the photonic control signal and
thus allows obtaining a polarization-sensitive modulator.

, SnSSe shows high hole mobilities and short relaxation time, resulting in potential applications in photoelectric devices. Here SnSSe is investigated for the ultrashort pulse generation in the mode-locked fiber laser. The prepared SnSSe saturable absorber (SA) exhibits a large modulation depth of 56.75%. Because of the saturable absorption characteristic of the SnSSe SA, mode-locked pulses as short as 158.6 fs with a signal-to-noise ratio of 94 dB are obtained at 1560.9 nm. The nonlinear exploration of SnSSe offers the possibility to explore further applications of SnSSe in near-infrared regions, especially for ultrafast photonic devices and modulators.
The consequences of Brexit on existing and future commercial contracts
Authors: Renaudin Muriel 
Published: December 2019

In this article Dr Muriel Renaudin (Lecturer in Law, School of Law and Politics, Cardiff University) argues that given that English contract law as a whole has predominantly remained untouched by European legislation, a continued membership in current trade agreements will avoid the uncertainties created by Brexit and will ensure that principles of commercial law such as predictability, security and low costs are maintained.

Study of the Viscosity of a La2O3-SiO2-FeO Slag System
Authors: Xin Wenbin , Deng Yongchun , Jiang Yinju , Wang Yongqiang 
Published: December 2019

Abstract
The viscosity and break temperature of La2O3–SiO2-FeO slag was investigated to develop low-Al2O3 or Al2O3-free slag for the effective recovery of rare-earth metals. When La2O3 content is fixed (45, 50 and 55 mass%), the viscosity and break temperature of La2O3–SiO2-FeO slag decrease with an increase in FeO content and a decrease in SiO2 content. A higher La2O3 content in the La2O3-SiO2-FeO ternary slag yields a lower slag viscosity but a higher break temperature. Individual minor components of Al2O3, MnO and B2O3 does not affect, or decreases slightly the viscosity of La2O3–SiO2-FeO slag, whereas the slag break temperature is reduced so that the reduction ability order is ranked as B2O3 > Al2O3 > MnO. A small amount of two components Al2O3 + MnO and Al2O3 + B2O3 has little effect on the viscosity of the slag but it has an additive effect on the slag break-temperature reduction.

Authors: Li Jianjie , Zhao Mingliang , Zhang Ming , Cheng Xingxing , Chang Jingcai , Wang Zhiqiang , Fu Jiapeng , Sun Yiqing , Liu Xiuru 
Published: December 2019

Abstract
Fe/ZSM-5 catalysts were prepared by three kinds of ion exchange methods: aqueous ion-exchange (AI), hydrothermal ion-exchange (HI) and solid-state ion-exchange (SI). Their catalytic activities were tested for NOx reduction by CO in a separated NOx adsorption-desorption process. In this paper, performances of adsorption, reduction and dynamic adsorption-reduction were all investigated. All three catalysts exhibited good reduction activity at above 300 °C. Fe/ZSM-5(SI) exhibited excellent NOx removal efficiency in the dynamic adsorption-reduction experiments. However, in the dynamic process the adsorption efficiency of Fe/ZSM-5(AI) and the reduction efficiency of Fe/ZSM-5(HI) is not very good. The catalysts were further characterized by SEM, BET, XRD, XRF, XPS and TPD. It was found that the Fe content of the Fe/ZSM-5(SI) was the highest. Further, Fe is supported in the form of Fe2O3 particles. Bronsted acid sites were also playing a major role in the high catalytic activity. TPD and in situ DRIFT experiments show that more Fe loading in α acid sites could result in a higher NOx removal efficiency.

Published: December 2019

Abstract
For centuries, Hirudo medicinalis (medicinal leech) has been used as a remedy to treat many discomforts, such as muscle and joint pain. Nowadays, using leech in reconstructive surgery, microsurgery, wound and flap healing, venous insufficiency, varicosities and many other disorders has increased. In this study, we report a 45 year old female patient with six pruritic papules on her legs since10 months ago that appeared about 4 weeks after one session of leech application. Skin biopsy was performed on one of the papules, and in histopathology, superficial ulceration with a dense superficial and deep inflammatory infiltrate within the dermis composed of lymphocytes and eosinophils detected that considering history of leech application at this site, these constellation of data was compatible with the diagnosis of cutaneous lymphoid hyperplasia induced by leeches and the patient was cured by a topical steroid and cryotherapy.

Authors: Walsh Elizabeth T. , Hunter Janel D. , Crudo David F. , Constantacos Cathrine 
Published: December 2019

Abstract

Background
Radioactive iodine (RAI) therapy is prevalent in the treatment of Graves’ disease. Adverse effects in pediatrics are not well-described.

Case presentation
A 13-year-old female underwent RAI therapy for Graves’ disease. Eight days later, she developed facial pain and forehead burning. She was diagnosed with sinusitis and started on pseudoephedrine with resolution in 24 h.

Conclusions
She endured prolonged discomfort due to an under-recognized adverse effect of RAI. Studies identify the nose as a site of RAI accumulation and smaller nasal passages may predispose children to sinusitis. We report the first pediatric case of sinusitis following RAI. With the increasing use of RAI to treat Graves’ disease, clinicians must recognize this adverse effect.
Experimental Determination of the Belt Transmission Slip
Authors: Mascenik Jozef , Murcinkova Zuzana 
Published: December 2019

AbstractThe presented paper provides the alternative options for determining the condition of belt gear based on the testing and monitoring. In order to carry out experimental measurements, a newly developed device for testing, monitoring and diagnostics of belt drives was designed, as well as the possibility of determination of limit states by extreme loads. The designed measuring stand allows to determine the point of destruction of the belt for an extreme load. The main objective of the experimental measurement was to determine the slip of the wedge-shaped belt. The slip was evaluated by the coefficient of belt creeping and the specific belt slip by means of the measuring stand. The measurements on the proposed device can be made when the input speed from the electric motor and the transmitted torque of the belt gear are constant while the tensioning force of the belt drive is changing or the measurements can be made when the tensioning force and input speed of the belt drive are constant and the torsional moment changes. The monitoring of specified parameters for determining the belt gear slip is made by means of sensors located at predetermined locations from which data is processed by a PC. In the paper, the analytical calculation is processed, from which the values are compared with the values measured on the proposed device.

Abstract
The article deals with the use of acoustic emission to identify the formation of cracks during the mechanical loading in the corrosive attacked weldment S235JR+N. The experiment includes the methodology for continual record of emissive signals, data analysis and monitoring of material response to monitor mechanical stress effect in real time. There is possibility to observe response of corrosive degraded samples in real time during mechanical stress through the suitably designed methodology of detection, process and analysing of acoustic emission signals. It is possible to gain new information about processes rising inside the material by this way of data measurement. The signals of acoustic emission can be used as the way of identification for the micro cracks rising in the inner and also external structure of effortful materials.

Published: December 2019

Abstract
The main aim of presented article is to present methodology how sophisticated products as compressor equipment can be considered and analysed as a complex technical system which consists of jointly operating components – a set of hardware, software, operational staff and documented information. In process modelling, these components are interacting in different processes of inputs, outputs, mechanisms (resources) or management. Based on the regulatory requirements for each component of the system, a key efficiency indicator can be identified. This allows to control the process and make appropriate decisions to improve the system. The application of the proposed methodology for the development and implementation of an integrated management system reduce the cost of resources and significantly improve the quality of the implementation of processes.

Authors: Xie Yuan , Wei Wei , Meng Fanbin , Qu Xi , Li Jinyang , Wang Li , Zhou Zuowan 
Published: December 2019

Abstract
In response to the widespread bacterial threat, mechanical bactericidal nanostructures with various morphologies have been reported for years. However, the relationship between morphology and bactericidal properties is still yet to be elucidated due to the lack of a fair comparison under similar density of the nanostructures. For this purpose, an electrical-field assisted hydrothermal growth method were utilized to prepare the ZnO nanoarrays with similar array density (1.9×109 rod·cm2-2.4 ×109 rod·cm2) but gradient morphologies from hexagonal prism, hexagonal prismoid to hexagonal pyramid on stainless steel sheets. Moreover, in dark condition, a bactericidal activity was observed on the ZnO nanoarray surfaces within 30 min contact for both E. coli and S. aureus cells. The bactericidal rate was rapidly enhanced as the average tip width of the nanorods decreasing from 137 to 38 nm. These results suggest that the hexagonal pyramid ZnO nanoarrays have a rapid, efficient and broad-spectrum bactericidal activity, which could contribute to the next-generation aquatic pathogens control strategies.

Abstract
Small Angle X-ray Scattering (SAXS) is an ideal characterization tool to explore nanoscale systems. In order to investigate nanostructural changes of materials under realistic sample environments, it is essential to equip SAXS with diverse in situ capabilities based on the corresponding requirements. In this paper, we highlight the representative experimental setups and corresponding applications of five widely used in situ capabilities: temperature, pressure, stretching, flow-through, and electric field. Additionally, we also briefly introduce other four in situ techniques including humidity, high-throughput, rheology, and magnetic field.

Market Power and Marginal Cost Effects in Competing Markets: Evidence from Airline Mergers
Authors: Le Huubinh B. , Yimga Jules 
Published: December 2019

Abstract
There are both market power and cost efficiency effects associated with airline mergers. Previous studies, however, have primarily focused on merger price effects, which is the net effect of these two forces. This paper attempts to decompose and measure these effects by using a model that allows us to derive proxies for market power and cost efficiency. In particular, we are interested in merger effects in markets where the merging airlines directly competed prior to their merger. We study two main mergers – Delta/Northwest and United/Continental – and find that both increase market power in markets where the merging airlines competed prior to merger. We also find evidence of marginal cost efficiencies associated with both mergers. These efficiency effects are relatively larger than the market power effects and come from different sources. In the case of the Delta/Northwest merger, efficiencies come from markets where the merging airlines competed prior to the merger, whereas in the case of United/Continental, they come from markets where the merging firms did not compete. The market power effects only stem from markets with pre-existing competition among merging airlines, perhaps due to the elimination of a competitor in those markets. These findings, thus, support the long-standing hypothesis that market power and efficiency are important in motivating horizontal mergers.
