Published: June 2017

AbstractAn environment-friendly fluorescent nano-hybrid hydrogel has been synthesized successfully, from cellulose nanocrystal (CNC), acrylic acid (AA) and phosphorescent Eu2+/Dy3+doped SrAl2O4via free radical polymerization. The hydrogel network matrix fixed Eu2+/Dy3+doped SrAl2O4nanoparticles by polymer chains with coordinate bonds that prevented particles from aggregating and quenching in water. The fluorescent nano-hybrid hydrogel exhibited extremely high water absorption of which the swelling ratio in distilled water and NaCl salt solution were respectively of 323.35 g/g and 32.65 g/g. Furthermore, the hydrogel displayed excellent water retention property that can keep half of the moisture even exposed to 80 °C for 210 min. Besides, the hydrogel had bright green fluorescence under the sunlight or ultraviolet excitation, and the fluorescence intensity was up to 125477 after swelling 50 times in water. The time-resolved photoluminescence (TRPL) afterglow decay examination showed that the fluorescent emission persisted for 4 h after hydrogels excited at 368 nm wavelength UV-light for 10 min. The fluorescence intensity behaved significant linear relationship with the swelling ratio. As a result, these hydrogels were considered as promising candidates for the preparation of stable and sensitive sensor materials in green water detection.

AbstractSelenoprotein biosynthesis relies on the co-translational insertion of selenocysteine in response to UGA codons. Aminoglycoside antibiotics interfere with ribosomal function and may cause codon misreading. We hypothesized that biosynthesis of the selenium (Se) transporter selenoprotein P (SELENOP) is particularly sensitive to antibiotics due to its ten in frame UGA codons. As liver regulates Se metabolism, we tested the aminoglycosides G418 and gentamicin in hepatoma cell lines (HepG2, Hep3B and Hepa1-6) and in experimental mice. In vitro, SELENOP levels increased strongly in response to G418, whereas expression of the glutathione peroxidases GPX1 and GPX2 was marginally affected. Se content of G418-induced SELENOP was dependent on Se availability, and was completely suppressed by G418 under Se-poor conditions. Selenocysteine residues were replaced mainly by cysteine, tryptophan and arginine in a codon-specific manner. Interestingly, in young healthy mice, antibiotic treatment failed to affect Selenop biosynthesis to a detectable degree. These findings suggest that the interfering activity of aminoglycosides on selenoprotein biosynthesis can be severe, but depend on the Se status, and other parameters likely including age and general health. Focused analyses with aminoglycoside-treated patients are needed next to evaluate a possible interference of selenoprotein biosynthesis by the antibiotics and elucidate potential side effects.

Published: June 2017

AbstractSite-specific gene expression analyses are important for understanding tissue functions. Despite rapid developments in DNA-related technologies, the site-specific analysis of whole genome expression for a tissue remains challenging. Thus, a new tool is required for capturing multiple tissue micro-dissections or single cells while retaining the positional information. Here, we describe the development of such a system, which can pick up micro-dissections by punching a tissue repeatedly in a very short period, e.g., 5 s/sampling cycle. A photo of the punched tissue provides information on the dissected positions, allowing site-specific gene expression analysis. We demonstrate the site-specific analysis of a frozen tissue slice of mouse brain by analyzing many micro-dissections produced from the tissue at a 300-μm pitch. The site-specific analysis provided new insights into the gene expression profiles in a tissue and on tissue functions. The analysis of site-specific whole genome expression may therefore, open new avenues in life science.

Published: June 2017

AbstractThe discharge of engineered nanomaterials (ENMs) into environment is raising widespread concern not only due to their direction bio-toxicity but also their bio-concentration and bio-magnification through food web. However, the transformation and distribution of ENMs during food-chain transport are poorly understood, due to lack of accurate, reliable analytical methods. In this study, by using a suite of advanced spectrum techniques, we successfully tracked the distribution and biotransformation dynamics of CdSe quantum dots (QDs) during their transport fromShewanella onedensistoCaenorchabditis elegansin predation. Fluorescence microscopy and Raman mapping showed that the ingested QDs byC. eleganswere located at the gut lumen and subcutaneous tissue, and were partially excreted from the nematode body over time. Micro-X-ray fluorescence (μ-XRF) spectroscopy and Se K-edge X-ray absorption fine structure (XAFS) results further revealed the changed distribution of Se element over time, and a shift in the major Se species from CdSe to Se0and Na2SeO3IV. This work demonstrates the utility of advanced spectral techniques for characterizing QDsin vivo, and may facilitate a better understanding on the environmental transformation and fates of ENMs.

Authors: Kang J. , Moon J.‐S. 
Published: June 2017

Wideband high‐power single‐chip X‐band class‐F power amplifier with excellent output performances is reported. In order to achieve high‐power class‐F operation under minimised output capacitance impact at the frequency, high‐voltage operation with minimised device size is pursued and its voltage swing becomes maximised by adopting high breakdown field‐plate (FP) GaN high‐electron‐mobility transistor (HEMT) devices with cascode configuration. For the fabrication, 0.14 µm FP AlGaN/GaN HEMT technology with 58 GHz fT and ∼100 V breakdown is used. Based on on‐wafer test at 44 V Vdd, the fabricated class‐F power amplifier delivers maximum 61.1% power added efficiency (PAE) with 9.2 W at 10.2 GHz. With the help of high‐voltage operating cascode devices of minimised size, it also delivers excellent bandwidth of 1.6 GHz at the point of 50% PAE and high‐power density of 4.42 W/mm is demonstrated.

Published: June 2017

In this study, a new modified switched boost inverter (MSBI) is proposed. The proposed inverter presents higher voltage gain in comparison with conventional Z‐source inverter and switched boost inverter. Moreover, the proposed inverter provides zero voltage switching turn‐off of input voltage source side switches. In this study, the proposed converter is theoretically analysed in different operational modes along with design procedure and ripple analysis. The proposed MSBI is compared with similar works to evaluate its capabilities. Finally, a 50 kHz experimental prototype with input voltage of 40 V is used to verify the analysis and simulation results.

Published: June 2017

Objective This study aims to compare mechanography, measuring force in jumping, and rising, with the 6-minute walk test (6MWT) and time function tests in pediatric patients with hereditary motor and sensory neuropathies.
Methods A cohort of 23 patients performed the 6MWT and time function tests (time to run 10 m, to rise from a supine position, and to climb four stairs), as well as the chair rising test (CRT) and the single two-legged jump (S2LJ) on a mechanography ground reaction force platform. Results were correlated calculating linear regression.
Results Correlation revealed high or moderate correlation between mechanography and the 6MWT and the time function tests: S2LJ/6MWT = 0.64; CRT/6MWT = 0.52; S2LJ/rising from floor = 0.63; CRT/rising from floor = 0.67; S2LJ/10 m run = 0.74; CRT/10 m run = 0.66; S2LJ/climb four stairs = 0.56; CRT/climb four stairs = 0.47.
Conclusion Jumping mechanography is a good additional tool for the assessment of pediatric patients with Charcot-Marie-Tooth disease and might be used for primary outcome measures. It was not feasible in more advanced stages of the disease. In less disabled children, the S2LJ, which quantifies force generated by proximal and distal muscles, might be superior to other tests.
Intramedulläre Stabilisierung und Augmentation mit unter Licht polymerisierendem Methylmethacrylat
Authors: Bail Hermann 
Published: June 2017

ZusammenfassungEin neues Verfahren ermöglicht durch das Einspritzen eines Monomers in einen minimalinvasiv intramedullär eingebrachten Ballon mit anschließendem Auspolymerisieren unter Blaulicht die gezielte Stabilisierung und Augmentation insbesondere von osteoporotischen und/oder metastatischen Frakturen. An den oberen Extremitäten kann das ausgehärtete Methylmethacrylat als Stand-alone-Implantat zur Frakturstabilisierung dienen. Es eignet sich auch – vor allem an den unteren Extremitäten – zur intramedullären Augmentation z. B. einer winkelstabilen Plattenosteosynthese im Sinne einer verlängerten Verbundosteosynthese. Bisher gibt es nur wenige klinische Daten bez. dieses Verfahrens, es existieren vor allem Kongressberichte. Das Verfahren muss seinen Wert noch in größeren Fallserien und vergleichenden Studien unter Beweis stellen. Dennoch scheint es eine Option zur Verbesserung der Versorgung von Frakturen bei stark reduzierter Knochensubstanz darzustellen.
Zementaugmentation am proximalen Humerus
Authors: Plecko Michael 
Published: June 2017

ZusammenfassungOsteoporotische Frakturen am proximalen Humerus stellen auch heute noch, trotz der stark verbesserten Implantate und der verfeinerten Operationstechnik, eine große Herausforderung dar. Neben der Komplexität der Frakturen und den häufigen Komorbiditäten dieser Patienten ist es vor allem der schlechte Halt der Implantate im osteoporotischen Oberarmkopf, der zu einer hohen Rate an Komplikationen führt. Hier stehen der sekundäre Repositionsverlust und das Durchschneiden bzw. Ausreißen der Schrauben an führender Stelle. Durch Verbesserung des Knochen-Implantat-Interfaces kann die In-situ-Schraubenaugmentation mit Knochenzement deren Halt deutlich verbessern und damit ein Nachsinken der Fragmente verhindern und trotz der schlechten Knochenqualität eine frühfunktionelle Nachbehandlung ermöglichen.

Abstract
Background and study aims Cold snare polypectomy (CSP) for small colorectal polyps has lower incidence of adverse events, especially delayed postpolypectomy bleeding (DPPB). However, few data are available on comparisons of the incidence of DPPB of CSP and hot polypectomy (HP). The aim of this study was to evaluate the incidence of DPPB after CSP and compare it with that of HP. A propensity score model was used as a secondary analysis.
Patients and methods This was a retrospective cohort study conducted in a single municipal hospital. We identified 539 patients with colorectal polyps from 2 mm to 11 mm in size who underwent CSP (804 polyps in 330 patients) or HP (530 polyps in 209 patients) between July 2013 and June 2015.
Results There were no cases of DPPB in the CSP group. Conversely, DPPB occurred in 4 patients (1.9 %) after HP, resulting in a significant difference between the CSP and HP groups (0.008 % vs 0 %, P = 0.02). Propensity score-matching analysis created 402 matched pairs, yielding a significantly higher DPPB rate in the HP group than CSP group (0.02 % vs 0 %, P = 0.04). However, significantly more patients in the CSP group had unclear horizontal margins that precluded assessment (83 vs 38 cases, P < 0.001). The retrieval failure rate was significantly higher in the CSP group than in the HP group (3 % vs 0.7 %, P = 0.01).
Conclusions DPPB was less frequent with CSP than HP, as selected by the propensity score-matching model. Our findings indicate that CSP is recommended polypectomy in daily clinical setting. However, special care should be taken during polyp retrieval and horizontal margin assessment, and these issues could be taken into account in follow-up after CSP.
Minoritätenstress und soziale Unterstützung: Eine Online-Untersuchung zum Wohlbefinden von Trans*Personen in der
Schweiz

Published: June 2017

ÜbersichtTrans*Personen sind in unserer Gesellschaft in einem bedeutenden Ausmaß von Stigmatisierung und Ablehnung betroffen. Das
Minoritätenstressmodell sagt vorher, dass Nicht-Akzeptanz der Geschlechtsidentität durch andere Menschen sowie internalisierte Transphobie
bei Trans*Personen mit vermindertem psychischen Wohlbefinden zusammenhängen. Im Rahmen der vorliegenden Studie wurden 90 Trans*Personen in
der Schweiz zu erlebter Nicht-Akzeptanz der Geschlechtsidentität, internalisierter Transphobie, Lebenszufriedenheit und psychischer
Belastung befragt. Zusätzlich wurde die soziale Unterstützung als Resilienzfaktor erhoben. Wie erwartet, zeigte sich neben einer hohen
Prävalenz an psychischer Belastung eine starke negative Korrelation zwischen Minoritätenstress und Wohlbefinden. Internalisierte Transphobie
mediierte zudem den Zusammenhang zwischen der Nicht-Akzeptanz der Geschlechtsidentität und dem Wohlbefinden. Ebenfalls konnten
Moderationsanalysen aufzeigen, dass soziale Unterstützung den negativen Zusammenhang zwischen internalisierter Transphobie und Zufriedenheit
teilweise abschwächt. Die Ergebnisse stützen das Minoritätenstressmodell. Offene Forschungsfragen speziell zum Minderheitenstress
unterschiedlicher Teilgruppen von Trans*Personen werden angesprochen.

Significance
Water freezing into ice has a number of fascinating outcomes: Dendritic solidification of water results in beautiful snowflakes, a sealed bottle of beer shatters in a freezer, and ice covering salty oceans at the poles is salt-free due to compositional segregation. A silicon–germanium (SiGe) material system, ubiquitous in microelectronics, is surprisingly similar to water in its solidification behavior. Quenching of molten SiGe microdroplets sealed inside a glass fiber leads to dendritic morphology, with potential use in solar cells. Slow cooling induces compression of these spheres to tens of thousands of atmospheres, potentially changing the band structure of these materials. Moreover, slow solidification results in compositionally segregated SiGe Janus particles, useful for high-frequency microelectronic and nanorobotic applications.
From visual perception to inference in the French evidential markersil m’est avis que,apparemment, andil paraît que
Authors: Rodríguez-Somolinos Amalia 
Published: June 2017

AbstractThis article studies the evolution, from Medieval to Modern French, of three evidential markers that are semantically related from a diachronic perspective:il m’est avis que‘I think that’, ‘it seems to me that’,apparemment‘apparently’, andil paraît que‘it seems that, apparently’. This study demonstrates the rise of the modal and evidential uses of the markers in question, from the Medieval period onwards, and provides a semantic characterization of these three epistemic-evidential markers in order to precisely grasp the evolution of their meaning. Using information from a number of databases, this article provides empirical support for the study of the different types of evidentiality, their evolution, and their interaction with the epistemic commitment of the speaker and the degree of certainty. The three markers have evolved towards greater subjectivity and a lower degree of certainty. Their historical semantic description shows that a marker may shift diachronically between various types of evidence.
The rise and development of parentheticalneedless to say
Authors: Blanco-Suárez Zeltia , Serrano-Losada Mario 
Published: June 2017

AbstractThe article traces the diachronic development of the assumed evidentialneedless to say. This parenthetical expression allows the speaker to make certain assertions regarding the obviousness of what s/he is about to say, thus serving as an evidential strategy that marks the information conveyed as being based on inference and/or assumed or general knowledge. Parentheticalneedless to sayhas its roots in the Early Modern Englishneedless to-infconstruction (meaning ‘it is unnecessary to do something’), which originally licensed a wide range of infinitives. Over the course of time, however, it became restricted to uses with utterance verbs, eventually giving rise to the grammaticalized evidential expressionneedless to say. In fact, it is only in Late Modern English that the evidential pragmatic inferences become conventionalized and that the first parenthetical uses of the construction are attested. In Present-day English, parentheticalneedless to sayoccurs primarily at the left periphery with forward scope.
Miratives in Japanese
Authors: Shimada Masaharu , Nagano Akiko 
Published: June 2017

AbstractThe notion of mirativity as a grammatical category separate from evidentiality is controversial, but a certain amount of cross-linguistic evidence speaks for its validity. The aim of this study is to investigate this notion in contemporary and earlier Japanese, which is shown to have mirative constructions: (i)nomiratives, (ii)kotomiratives, and (iii) lexical miratives. The particlesnoandkotoare polyfunctional, and they have recently gained a mirative function. Lexical miratives are uttered by the younger generation. These findings raise a diachronic issue regarding the emergence of the three mirative constructions. AdoptingCruschina’s (2011)cartographic approach to discourse-related phenomena and the notion of “emotional vocative” offered byYamada (1936), we argue that what binds the three constructions together is the involvement of the IFocP (Information Focus Phrase) and that their emergences are all explained by grammaticalization paths starting from nominals.
The Commercial Trap Fishery in the Commonwealth of Puerto Rico: an Economic, Social, and Technological Profile
Authors: Agar J. , Shivlani M. , Solís D. 
Published: June 2017

Abstract
In this paper, we describe the socioeconomic conditions of the small-scale trap fishery in the Commonwealth of Puerto Rico and examine the determinants affecting the technical performance of the fleet. The socioeconomic data used in the analysis were derived from random, in-person interviews with 50 trap fishers, which accounted for about one-third of the active trap fishers. The study found that the fishery is composed of middle-aged, small-scale commodity producers who use traditional, capital-intensive technologies to target Caribbean spiny lobsters Panulirus argus and various reef fishes. Fishers reported that fishing made up 74% of their household income. We also explored the factors influencing the technical efficiency of the fleet by using a stochastic production frontier model. The analysis suggested that trap operations could increase their gross revenues per trip by 36%, on average, by using current input levels and technology more efficiently. The fleet exhibited decreasing returns to scale. The study also found that a 10% increase in the number of traps tended would raise gross revenues by 0.9% and that baiting traps would raise gross revenues by 1.4%. The analysis suggested that fishing experience and kinship ties were the key determinants of technical efficiency. We also explored the policy implications stemming from these results.

Localization of the CAPRICE-ENHANCER OF TRY AND CPC1 chimera protein in Arabidopsis root epidermis
Authors: Tominaga-Wada Rumi , Kurata Tetsuya , Wada Takuji 
Published: June 2017

Abstract
The CAPRICE (CPC) encodes an R3-type MYB transcription factor, which promotes root-hair differentiation. Previously, we showed that the CPC protein moves from the non-hair cell to the neighboring cell and induces root-hair differentiation in Arabidopsis. In addition, we proposed two cell-to-cell movement signal sequences, S1 and S2, in CPC. However, an S1:2xGFP:S2 chimera protein did not move between root epidermal cells. Here, we show that the S1 and S2 sequences do not confer cell-to-cell movement or nuclear localization ability to a GFP protein. The ENHANCER OF TRY AND CPC1 (ETC1) gene encodes the CPC homolog R3 MYB; this protein does not possess cell-to-cell movement ability or the S1 sequence. To elucidate whether the S1 sequence can induce cell-to-cell movement ability in ETC1, CPCp:S1:ETC1:2xGFP was constructed and introduced into Arabidopsis. Our results indicate that the addition of the S1 sequence was not sufficient for ETC1 to acquire cell-to-cell movement ability.
