Published: May 2019

AbstractRuthenium (Ru)@Ordered mesoporous carbon (OMC) is a key catalyst in fine‐chemical production. In general, the OMC support is prepared by a wet self‐assembly requiring excessive solvent, toxic phenol–aldehyde precursors and a long reaction time, followed by post‐immobilization to load Ru species. Herein, we wish to report a solid‐state, rapid, and green strategy for the synthesis of Ru@OMC with biomass tannin as the precursor. The chemistry essence of this strategy lies in the mechanical‐force‐driven assembly, during which tannin‐metal (Zn2+ and Ru3+) coordination polymerization and hydrogen‐bonding interactions between tannin‐block copolymer (PEO‐PPO‐PEO, F127) simultaneously occur. After thermal treatment, Ru@OMC catalysts with mesoporous channels, narrow pore‐size distribution (≈7 nm), and high surface area (up to 779 m2 g−1) were directed by F127 micelles. Meanwhile, the Zn2+ ions dilute Ru3+ and avoid the sintering of Ru species, resulting in Ru clusters around 1.4–1.7 nm during carbonization (800 °C). Moreover, the Ru@OMC catalyst afforded a good activity (TOF: up to 4170 h−1) in the selective oxidation of benzyl alcohol to benzaldehyde by molecular oxygen.

AbstractHemolysis is an unintended sequel of temporary or permanent intracardiac devices. However, limited data exist on the characteristics and treatment of hemolysis in patients with cardiac prostheses. This entity, albeit uncommon, often poses significant diagnostic and management challenges to the clinical cardiologist. In this article, we aim to provide a contemporary overview of the incidence, mechanisms, diagnosis, and management of cardiac prosthesis‐related hemolysis.

Published: May 2019

BackgroundThe optimal imaging for the staging of oropharyngeal cancer is not well defined.MethodsThe linked Surveillance, Epidemiology, and End Results (SEER)–Medicare database for 2006 through 2011 was used to compare patient characteristics and hospital region by the initial imaging modality used for patients with oropharyngeal cancer. The primary outcome was 3‐year cancer‐specific survival (CSS). Cox proportional hazards models were adjusted for imaging, age, sex, region, education, race, American Joint Committee on Cancer stage of disease, and treatment, which were examined using backward elimination. The authors also explored how initial imaging use varied by patient characteristics and hospital region.ResultsA total of 1765 patients underwent initial diagnostic imaging. Of those, approximately 11.4% (202 patients) received computed tomography (CT) alone as their initial imaging modality, 5.2% (91 patients) underwent magnetic resonance imaging (MRI) without positron emission tomography (PET), and 83.3% (1472 patients) had initial imaging that included PET. The overall 3‐year CSS rate for the entire population was 63.7%. In the adjusted survival models compared by initial imaging modality, patients who underwent a PET examination were found to have higher survival than those who underwent CT alone or MRI, respectively (hazard ratio, 1.337 [95% CI, 1.001‐1.785; P = .0491]; and hazard ratio, 1.748 [95% CI, 1.2‐2.545; P = .0036]).ConclusionsAmong patients with oropharyngeal cancer, initial staging with PET imaging was associated with improved 3‐year CSS compared with initial staging with MRI or CT.

BackgroundThe current study was performed to evaluate the influence of race on the association between biopsy grade group (GrGp) and the risk of detectable prostate‐specific antigen (PSA) and adverse histopathological outcomes after radical prostatectomy (RP).MethodsData regarding 4073 men (1344 African American men; 33%) who were treated with RP were categorized based on the 5‐tiered GrGp system. Logistic regression was used to test the association between biopsy GrGp and PSA nadir (<0.1 ng/mL) after RP as well as adverse pathological features among all patients and stratified by race.ResultsThose patients with a higher biopsy GrGp were found to have lower odds of achieving a PSA nadir <0.1 ng/mL after RP on unadjusted and multivariable analysis (both P < .001). On unadjusted and multivariable analysis, higher GrGp was associated with increased odds of each of the adverse pathological features, namely, GrGp ≥3, extraprostatic extension, seminal vesicle invasion, positive surgical resection margin, and positive lymph nodes (all P < .001). Race had no significant interaction with biopsy GrGp in the prediction of PSA nadir after RP (P = .91) or any adverse pathological features (all P > .06) except positive lymph nodes. When the models were stratified by race, the associations between preoperative biopsy GrGp and having a PSA nadir <0.1 ng/mL, high‐grade final pathology, or other adverse histopathologic features were similar in both races except as noted for positive lymph nodes.ConclusionsHigher preoperative biopsy GrGp is associated with increased odds of adverse histopathological findings as well as lower odds of a PSA nadir <0.1 ng/mL after RP. These associations are largely independent of race, suggesting that GrGp is an accurate tool for risk stratification in both black and white men.
A One‐Step Chemical Strategy for the Formation of Carbon Nanotube Junctions in Aqueous Solution: Reaction of DNA‐Wrapped Carbon Nanotubes with Diazonium Salts

Published: May 2019

AbstractA single‐step chemical strategy allows the formation of single‐walled carbon nanotube (SWCNT) molecular junctions in aqueous solution. SWCNTs were first wrapped with DNA to be water soluble and solution processable. Diazonium salts, which have been shown to react spontaneously with carbon nanotubes in water at room temperature, were then employed to covalently link SWCNT segments. The DNA wrapping of the nanotubes acted as a protective layer that limits the functionalization predominantly to the nanotube terminal ends, therefore allowing the assembly of linear SWCNT junctions. Upon increasing the concentration of the linker, we observed first the formation of side‐to‐end junctions, and eventually the assembly, through side‐to‐side interactions, of SWCNTs into bundles. This approach demonstrates the possibility of tuning the formation of linear and branched carbon nanotube junctions that in turn is of importance for the sustainable fabrication of solution‐processable CNT‐based nanoscale systems and devices.

AbstractThe relevance of personal recovery receives increasing attention in mental health care and is also important for people with bipolar disorder (BD). There is a need for reliable and valid instruments measuring personal recovery. Therefore, the current study evaluated the psychometric properties of a Dutch translation of the Questionnaire about the Process of Recovery (QPR) in a sample of people with BD and explored the relationship with constructs of well‐being, social role participation, and psychopathology. A cross‐sectional survey study was conducted in which 102 people diagnosed with BD completed the QPR. Factor structure of the QPR was evaluated by conducting confirmatory factor analyses (CFA), and internal consistency was assessed by calculating reliability coefficients. Convergent validation measures assessed well‐being, social role participation, and symptomatology. Incremental validity was determined by evaluating the ability of the QPR to explain variance in symptomatology above and beyond well‐being. Findings of the CFA supported a unidimensional factor structure, and internal consistency estimates were excellent. Scores of the QPR showed strong correlations with convergent measures, but were only weakly associated with manic symptomatology. Moreover, personal recovery explained additional variance in symptoms of depression and anxiety above and beyond well‐being, indicating incremental validity. The QPR appears to be a reliable and valid tool to assess personal recovery in people with BD. Our findings underline the importance of personal recovery in the context of treatment of BD. Personal recovery demonstrates a substantial overlap with well‐being.
Promoting Nucleation in Microwave‐Assisted Nanoparticle Synthesis Using Combined Two‐Stage Irradiation and Anti‐Solvent Addition

Published: May 2019

AbstractMicrowave is advantageous for nanoparticle synthesis because nanostructured crystals and mono‐dispersed nanoparticle size can be obtained due to the rapid growth induced by quick thermal response. In previous studies, it has been confirmed that an individual application of two‐stage irradiation and anti‐solvent addition is effective in promoting stable nucleation and smaller particle generation. Nevertheless, to date no studies have been reported in applying the two methods above simultaneously and examining their synergistic effect. This study, therefore, aims to investigate the possibility of producing finer particles using a stable operation without any superheating and abrupt bubble growth. From the experimental data, it is evident that the beneficial combined effect of two‐stage irradiation and addition of anti‐solvent on the stable finer nanoparticle formation could be observed and confirmed. It is expected that the findings and recommendations from this work may be useful in optimizing two‐stage microwave‐assisted nanoparticle synthesis with an addition of anti‐solvent.

AbstractDental age assessment plays a pivotal role in clinical practice, demographic studies, forensics, and courts of law but is affected by ethnic and geographic variations. The aim was to determine the population‐specific weighted scores needed when dental age is estimated using Demirjian's method for Saudi children and adolescents between the ages of 3 and 15 years. Design: A total of 298 panoramic radiographs were collected from Saudi Arabia. Dental age was assessed using Demirjian's method (1973). Chronological age was determined from the date of birth and the date on which the panoramic radiograph was taken for each individual. Between 3‐ and 15‐years age group, the Saudi boys had an estimated age of 9.07 ± 1.96 years and chronological age of 8.49 ± 2.30 years. The Saudi girls had an estimated age of 9.22 ± 1.93 years and chronological age of 8.78 ± 2.32 years. With Demirjian's method, the Saudi boys were 0.57 ± 1.48 years, and girls were 0.44 ± 1.66 years ahead of their chronological ages (p < .05). New population‐specific weighted scores were developed to convert dental age according to Demirjian's method into estimated ages in the contemporary Saudi Arabian population. This study can be used for further research and comparisons with other population groups, regions or communities.

Published: May 2019

AbstractSmall and medium enterprises (SMEs) are key actors in the implementation of the circular economy (CE) concept as a basis for creating sustainable societies. Thus, the main objective of this study is to identify key strategies and resources that may favor CE implementation in SMEs. These key strategies should encourage SMEs to develop eco‐innovations to gain competitive advantage and create and capture value that is coherent with nature. A mixed‐method approach that consisted of a literature review and a focus group for gathering qualitative data was used. This focus group was made up of experts such as researchers and practitioners from universities, sustainable SMEs, and consultancy firms in Spain. A set of strategies and internal and external factors were identified to help SMEs to implement the CE. Finally, some useful dynamic capabilities for implementing the CE in business performance were identified.

Published: May 2019

AbstractMethyl formate was produced in one pot through the hydrogenation of CO2 to formic acid/formate followed by an esterification step. The route offers the possibility to integrate renewable energy into the fossil‐based chemical value chain. In this work, a phosphine‐polymer‐anchored Ru complex was shown to be an efficient solid catalyst for the direct hydrogenation of CO2 to methyl formate. The 1,2‐bis(diphenylphosphino)ethane‐like polymer presented the highest activity with a turnover number (TON) of up to 3401 at 160 °C. The reaction parameters were systemically investigated to optimize the reaction towards the formation of methyl formate. This catalyst could be reused seven times without a significant decrease in activity. Evolution of the catalytic Ru center during the reaction was revealed, and a possible reaction mechanism was proposed.
Design of the CMOS inverter‐based amplifier: A quantitative approach
Authors: Sharroush Sherif M. 
Published: May 2019

SummaryThe CMOS inverter can be used as an amplifier if properly biased in the transition region of its voltage‐transfer characteristics (VTC). In this paper, the design of this amplifier is investigated with its merits and demerits illustrated and with the various trade‐offs involved in its design discussed. Specifically, the following performance metrics are discussed quantitatively: gain, area, linearity, maximum allowable swing, bandwidth, stability, noise factor, impedance matching, and slew rate. Also, the effect of process, voltage, and temperature (PVT) variations are investigated. The optimum number of stages corresponding to the minimum area required for achieving a certain voltage gain is determined. The results obtained from the quantitative analysis and the simulation are discussed.

Published: May 2019

AbstractAnorexia nervosa (AN) has been associated with a multitude of hypothalamic pituitary abnormalities, although it is unknown which aberrations reflect disease causation and which are the consequences of severe malnutrition. Among these endocrinopathies, hypothalamic–posterior pituitary aberrations have been described, including disorders of osmoregulation. We report the case of an adolescent female with a history of severe AN, restricting subtype, treated aggressively with multiple hospitalizations. During hospitalization for severe weakness and lethargy, her course of medical stabilization was complicated by significant polyuria, ultimately diagnosed as central diabetes insipidus (DI). This is the first reported case, to our knowledge, of a severely malnourished adolescent with AN—restricting subtype developing central DI during the refeeding process for medical stabilization, thus adding to the small body of existing literature on disordered osmoregulation in this patient population. This case report raises the question as to whether the frequency of central DI during refeeding is greater than that previously recognized. Additional research should focus on how neuroendocrine dysregulation of water balance might impact the clinical course of AN and its treatment.
Mycorrhiza‐mediated interference between cover crop and weed in organic winter cereal agroecosystems: The mycorrhizal colonization intensity indicator

Published: May 2019

AbstractThe mycorrhizal fungi are symbiotic organisms able to provide many benefits to crop production by supplying a set of ecosystem functions. A recent ecological approach based on the ability of the fungi community to influence plant–plant interactions by extraradical mycelium development may be applied to diversified, herbaceous agroecosystems. Our hypothesis is that the introduction of a winter cereal cover crop (CC) as arbuscular mycorrhizal fungi (AMF)–host plant in an organic rotation can boosts the AMF colonization of the other plants, influencing crop–weed interference. In a 4‐years organic rotation, the effect of two winter cereal CC, rye and spelt, on weed density and AMF colonization was evaluated. The AMF extraradical mycelium on CC and weeds roots was observed by scanning electron microscopy analysis. By joining data of plant density and mycorrhization, we built the mycorrhizal colonization intensity of the Agroecosystem indicator (MA%). Both the CC were colonized by soil AMF, being the mycorrhizal colonization intensity (M%) affected by environmental conditions. Under CC, the weed density was reduced, due to the increase of the reciprocal competition in favor of CC, which benefited from mycorrhizal colonization and promoted the development of AMF extraradical mycelium. Even though non‐host plants, some weed species showed an increased mycorrhizal colonization in presence of CC respect to the control. Under intense rainfall, the MA% was less sensitive to the CC introduction. On the opposite, under highly competitive conditions, both the CC boosted significantly the mycorrhization of coexistent plants in the agroecosystem. The proposed indicator measured the agroecological service provided by the considered CCs in promoting or inhibiting the overall AMF colonization of the studied agroecosystems, as affected by weed selection and growth: It informs about agroecosystem resilience and may be profitably applied to indicate the extent of the linkage of specific crop traits to agroecosystem services, contributing to further develop the functional biodiversity theory.

AbstractThis study investigates the distribution of Antarctic minke whales (AMW) in relation to sea ice concentration and variations therein. Information on AMW densities in the sea ice‐covered parts of the Southern Ocean is required to contextualize abundance estimates obtained from circumpolar shipboard surveys in open waters, suggesting a 30% decline in AMW abundance. Conventional line‐transect shipboard surveys for density estimation are impossible in ice‐covered regions, therefore we used icebreaker‐supported helicopter surveys to obtain information on AMW densities along gradients of 0%–100% of ice concentration. We conducted five helicopter surveys in the Southern Ocean, between 2006 and 2013. Distance sampling data, satellite‐derived sea‐ice data, and bathymetric parameters were used in generalized additive models (GAMs) to produce predictions on how the density of AMWs varied over space and time, and with environmental covariates. Ice concentration, distance to the ice edge and distance from the shelf break were found to describe the distribution of AMWs. Highest densities were predicted at the ice edge and through to medium ice concentrations. Medium densities were found up to 500 km into the ice edge in all concentrations of ice. Very low numbers of AMWs were found in the ice‐free waters of the West Antarctic Peninsula (WAP). A consistent relationship between AMW distribution and sea ice concentration weakens the support for the hypothesis that varying numbers of AMWs in ice‐covered waters were responsible for observed changes in estimated abundance. The potential decline in AMW abundance stresses the need for conservation measures and further studies into the AMW population status. Very low numbers of AMWs recorded in the ice‐free waters along the WAP support the hypothesis that this species is strongly dependent on sea ice and that forecasted sea ice changes have the potential of heavily impacting AMWs.
