Published: September 2018

AbstractObjectiveTo systematically review the evidence for interventions addressing key domains of the American Cancer Society (ACS) and American Society of Clinical Oncology (ASCO) Prostate Cancer Survivorship Care Guidelines: health promotion, surveillance, physical side effects, psychosocial management, and care coordination.MethodsWe conducted a systematic review of systematic reviews and meta‐analyses of interventions targeting ACS/ASCO guideline domains. All titles and abstracts were independently assessed for inclusion based on predetermined criteria. Relevant data were extracted, and assessment of methodological quality was performed.ResultsForty‐four systematic reviews of interventions targeting ACS prostate cancer guideline domains were included for review. Exercise and psychosocial interventions were effective for improving men's survivorship outcomes in the domains of health promotion, physical side effects, and psychosocial management. Across the domains, evidence quality varied and there was a limited diversity of participants. No reviews of interventions addressing surveillance and cancer care coordination were identified.ConclusionsThere are substantive knowledge gaps in prostate cancer survivorship research that are a barrier to real improvements in men's outcomes across the breadth of the survivorship experience. A targeted research and implementation agenda in prostate cancer survivorship is urgently needed if we are to meet the current and future burden of this disease on individuals, families, and communities.

Abstract3,3′‐diamino‐4,4′‐zoxyfurazan (DAAF) shows fascinating properties and can be practically applied in explosives and solid rocket propellants. Nano‐sized DAAF explosive particles were prepared by a low‐temperature and rapid crystallization process to improve energetic performance. The diameter and morphology of DAAF nanoparticles were characterized by Field emission scanning electron microscopy (FE‐SEM), Atomic force microscopy (AFM) and X‐ray diffraction (XRD). Nano‐DAAF shows irregular spherical nano‐particles with the diameter ranging from 50 to 100 nm. The size and morphology of nano‐DAAF particles can be tuned by temperature difference and DAAF concentration of crystallization process. The thermal properties were also investigated by Differential scanning calorimetry (DSC). For nano‐sized DAAF shows significantly decreased exothermal peak (259.3 °C) and enhanced energy release rate. Deflagration and short impulse shock waves experiments illustrated that nano‐DAAF explosive shows significantly improved initiation sensitivity compared to micro‐particles.

AbstractA novel reactive powder (aluminum/polytetrafluoroethylene, Al/PTFE 75/25 mass %) containing two kinds of PTFE (pre‐sintering PTFE and fresh PTFE, P‐PTFE and F‐PTFE) was prepared by a two‐step mechanical activation (MA) method. By introducing it into composite modified double base (CMDB) propellant, an attempt to improve the propellant performance of this mechanically activated Al/PTFE was made. Scanning electron microscopy (SEM) characterization indicated that F‐PTFE in activated powders deformed to abundant fibers under uniform shear forces. These fibers significantly enhanced propellant tensile properties and show improved safety performance. Compared to blank CMDB propellant (without PTFE), the elongation at maximum strength for propellant with activated Al/PTFE inclusions was increased to 3.7 times at −40 °C and to 3.9 times at −70 °C, the friction sensitivity and impact sensitivity were reduced by 88.9 % and 20.4 %, respectively. P‐PTFE in activated powders promoted the Al reaction activity, thereby reducing the propellant combustion agglomeration. The average diameter (D50) of coarse products for propellant with activated Al/PTFE 75/25 mass‐% was reduced by 82 % compared to that of blank CMDB propellant with spherical aluminum. This novel activated Al/PTFE shows increased propellant mechanical performance, decreased sensitivity and improved combustion efficiency of Al, which might expand the application field of CMDB propellants.

AbstractBACKGROUNDDifferences in population densities of Frankliniella occidentalis among different plant species suggest a preference for particular hosts. Host plant volatiles are often involved in insect fitness. However, few studies have explored the interaction between flower volatiles and fitness. The host fitness of F. occidentalis for different flowers was assessed through field investigation, and the olfactory preference of thrips for flower volatiles was tested in the laboratory.RESULTSIn the field study, 18 flower host plants were classified at four fitness levels by F. occidentalis. Olfactory tests showed that female F. occidentalis had significantly different preferences for different plant odours among the volatiles of the four tested flowers (each representing the four fitness levels), whereas male F. occidentalis did not. The relative response of F. occidentalis females to flower volatiles (Rosa rugosa > Dianthus caryophyllus > Gerbera jamesonii > Pelargonium hortorum) was consistent with the field performance of F. occidentalis. In total, 23, 29, 16 and 26 components were identified in the volatile profiles of R. rugosa, D. caryophyllus, G. jamesonii and P. hortorum, respectively. 3,5‐Dimethoxytoluene (24.94%), nonanal (30.42%), (E)‐3‐penten‐2‐one (52.31%) and zingiberene (29.88%) were the single most abundant components of the volatiles of R. rugosa, D. caryophyllus, G. jamesonii and P. hortorum, respectively.CONCLUSIONVolatiles are important in attracting F. occidentalis to suitable hosts, and differences in the types and concentrations of volatile components among flowers may directly influence the olfactory responses and field performance of thrips. Potential attractants could be developed for integrated pest management programmes against this pest. © 2018 Society of Chemical Industry
Information theoretic approach provides a reliable description for kinetic component of correlation energy density functional
Authors: Alipour Mojtaba , Badooei Zeinab 
Published: September 2018

AbstractIn recent years, much efforts have been invested to apply information theory for different physical and chemical problems. In this regard, one can make use of one or many of the information theoretic quantities together within an approach so‐called information functional theory to describe the energetic components and electronic properties of various systems. In the present contribution, several information theoretic quantities such as Fisher information, Shannon entropy, Onicescu information energy, and Ghosh–Berkowitz–Parr entropy based on the two representations of electron density and shape function are utilized for the prediction of kinetic component of the correlation energy density functional as an important quantity in density functional theory. Taking the atoms and isoelectronic series as benchmark sets we find that with more or less different accountabilities of the considered quantities they can be introduced as reliable measures for the kinetic energy functional. Concerning different natures of the information theoretic quantities with variety of scaling properties and physiochemical propensities, it is shown that instead of describing all data using one of such quantities individually, considering all of them concurrently provides a better view on the prediction of the kinetic component of correlation energy density functional. Hopefully, the information theoretic approach can provide an alternative pathway toward the theoretical prediction and rationalization of important quantities in density functional calculations from the perspective of information theory.

Abstract
Preclinical and clinical evidence suggests that mesenchymal stem cells (MSCs) may be beneficial in treating both acute myocardial infarction (AMI) and ischemic heart failure (IHF). However, the safety profile and efficacy of MSC therapy is not well-known. We conducted a systematic review of clinical trials that evaluated the safety or efficacy of MSCs for AMI or IHF. Embase, PubMed/Medline, and Cochrane Central Register of Controlled Trials were searched from inception to September 27, 2017. Studies that examined the use of MSCs administered to adults with AMI or IHF were eligible. The Cochrane risk of bias tool was used to assess bias of included studies. The primary outcome was safety assessed by adverse events and the secondary outcome was efficacy which was assessed by mortality and left ventricular ejection fraction (LVEF). A total of 668 citations were reviewed and 23 studies met eligibility criteria. Of these, 11 studies evaluated AMI and 12 studies evaluated IHF. There was no association between MSCs and acute adverse events. There was a significant improvement in overall LVEF in patients who received MSCs (SMD 0.73, 95% CI 0.24–1.21). No significant difference in mortality was noted (Peto OR 0.68, 95% CI 0.38–1.22). Results from our systematic review suggest that MSC therapy for ischemic heart disease appears to be safe. There is a need for a well-designed adequately powered randomized control trial (with rigorous adverse event reporting and evaluations of cardiac function) to further establish a clear risk-benefit profile of MSCs.

Published: September 2018

AbstractThe demand for the safe and efficient capture and storage of radioactive iodine is growing worldwide especially after the Fukushima accident. Herein, porous graphene materials, which were prepared by reduction of graphene oxide followed by chemical activation, are proposed for removal and storage of iodine. The effect of activation on the structure and porosity of the porous graphene was characterized. Owing to its high accessible space for iodine uptake, an iodine vapor adsorption capacity of 4110 mg g−1 was achieved, which is the highest value for solid carbon‐based adsorbents up to now. Quite different from that of adsorption of iodine vapor, the adsorption of iodine from solvent solution is less affected by the porosity of porous graphene. The adsorption kinetic data can be well represented by the pseudo‐second‐order model and the equilibrium data can be defined well to the Langmuir isotherm. These findings may offer not only a simple and efficient new approach for trapping harmful and radioactive iodine species by carbon materials, but also provide fundamental insight into the structure‐activity relationship of graphene materials for iodine adsorption.

Published: September 2018

Abstract2D hexagonal boron nitride, graphene, molybdenum disulphide and tungsten disulfide nanosheets were successfully prepared at mild temperature using a facile “recrystallization of NaCl” exfoliation method. The proposed method was simple, inexpensive and practical. The thicknesses of the h‐BN, graphene, MoS2 and WS2 nanosheets were approximately 1.5, 1.1, 1.2 and 1 nm, respectively. It was very interesting that the 2D nanosheets exhibited excellent thermal catalytic degradation performance during preparation of carbon quantum dots by using ethylene glycol. What's more, nitrobenzene (NB) was also degraded and the best degradation rate of NB was 71% at 6 h in the thermal catalytic system. This interesting discovery will lead to new research directions for two‐dimensional materials.

AbstractA multichannel fluorescence probe 8‐((((7‐(diethylamino)‐2‐oxo‐2H‐chromen‐3‐yl)methylene)hydrazono)methyl)‐7‐hydroxy‐4‐methyl‐2H‐chromen‐2‐one (probe 1) with “turn on” characteristics for selective and sensitive response toward Al3+, Hg2+ and ClO− was developed by mild condensation reaction of coumarin and ethanediamine. The probe could recognize Al3+, Hg2+ and ClO− with obvious change of fluorescence intensity in different mixture solution, and showed different maximum emission wavelengths in the presence of Al3+, Hg2+ and ClO− at 459 nm, 485 nm and 504 nm, respectively. More importantly, this probe has successfully been used in the monitoring of Al3+, Hg2+ and ClO− in tap water samples, and was resoundingly carried out imaging ClO− in living cells.

Published: September 2018

AbstractChemical evolution, from simple molecules to complex systems, is fundamental to modern origins of life research, and complex reaction networks are often supposed to have operated on the early Earth. Herein, a variety of compounds useful particularly for RNA synthesis − namely, cyanogen chloride, cyanamide, and nitrile precursors to simple sugars − are produced in short order by a chemical reaction network starting from hydrogen cyanide and driven by gamma radiolysis. The radiolytic yield of cyanamide was found to be proportional to the concentration of chloride, an often overlooked spectator anion. Aqueous irradiation of hydrogen cyanide in the presence of sodium chloride also affords cyanogen chloride, a possible intermediate in the radiolytic synthesis of cyanamide. Meanwhile, the synthesis of simple sugar precursors is proposed to proceed through a Kiliani‐Fischer homologation mechanism made possible by the reducing power of the solvated electron and hydrogen atom. Such a reaction network has the potential to serve as a model for better understanding and engineering chemical evolution of complex mixtures in the laboratory that could have happened on the early Earth.

Published: September 2018

AbstractA pair of diastereomers 2 a and 2 b were synthesized from the conjugation of bridging chiral de‐tert‐butylcalix[4]arene racemate 1 and (1S)‐(+)‐10‐camphorsulfonyl chloride. The diastereomeric separation by crystallization was explored in different solvents, temperature and time. The optimal crystallization procedures can afford them in a desirable yield, de and purity. A pair of enantiomers 1 a and 1 b were subsequently obtained after their hydrolysis. Moreover, their absolute configurations were determined by X‐ray crystallographic analysis. The crystallization results can match the large‐scale preparation of optically pure de‐tert‐butylcalix[4]arene in laboratory and industry.
Shedding New Light on Nanostructured Catalysts with Positron Annihilation Spectroscopy

Published: September 2018

AbstractInterest in new tools for the analysis of catalytic materials is growing due to the potential to enhance their functionality through the optimal nanostructuring, for example, of pore networks and surface properties. This prompts the need for improved descriptors to discriminate increasingly complex architectures. As a nondestructive, dynamic, and potentially, temporally, and spatially resolved tool, positron annihilation spectroscopy (PAS) can provide valuable complementary insights to already established (e.g., adsorption, spectroscopy, diffraction, and microscopy) methods. This is possible due to the specific sensitivity of positrons to the electronic environment, which determines their annihilation characteristics. However, despite growing enthusiasm, PAS is not widely known in the catalysis community. This review aims to highlight the many unique features, principles, and potential pitfalls of the technique, expanding on the outdated reviews on the topic, which are now over a decade old. After briefly introducing the principles, progress in the application of PAS to investigate various features of relevant catalytic materials is summarized. This includes the crystalline structure, presence of defects, pore connectivity and evolution, chemical properties, and adsorption phenomena. An improved understanding of the response will contribute not only to guiding the design of nanostructured materials but also to positioning PAS as a mainstream method for catalyst characterization.

Published: September 2018

AbstractIn this work, a filter‐based emulsification microextraction method is combined with high‐performance liquid chromatography for a fast, simple, and efficient determination of amphetamine and methamphetamine in the human plasma and pharmaceutical wastewater samples. In this method, in order to enhance the extraction speed without the use of a disperser solvent, the extraction solvent is dispersed as fine droplets in the sample solution, and a filtration step completes the extraction process by separation of the extraction phase from the sample solution. This method is centrifuge‐free, provides a good sample clean‐up, and is totally accomplished in about 60 s. In order to achieve the optimal experimental conditions, the effective parameters involved including the type and volume of the extraction solvent, pH of the sample solution, and ionic strength are thoroughly examined. Under the optimized experimental conditions, the calibration curves were obtained in the range of 3–2000 ng mL−1. The relative standard deviations for the method were in the range of 7.1–9.2% and the limits of detection ranged between 1.0 and 1.5 ng mL−1.
Assessment of three SPE cleanup sorbents efficiencies for determining neonicotinoid insecticides and selected metabolites in honey bees and bee pollen

Published: September 2018

AbstractThree sample cleanup methods (silica SPE, NH2‐silica SPE, and Z‐Sep SPE) based on solid‐phase extraction were investigated for determination of neonicotinoid insecticides and selected metabolites in honey bee and pollen samples by liquid chromatography with tandem mass spectrometry. Samples were extracted by acidified hexane and ethyl acetate and then cleaned up with a solid‐phase extraction cartridge packed with silica gel, which showed a better cleanup efficiency compared to the aminopropyl silica solid‐phase extraction and zirconium‐based sorbents method. Matrix effects of the three cleanup methods were evaluated and compared. Silica gel showed the highest analyte recoveries and method detection limit for this method were 2.0 to 9.1 μg/kg for honey bees and 2.4 to 4.7 μg/kg for pollen. Recovery studies were performed at three spiking levels (10, 60, and 120 μg/kg) and ranged from 78 to 140% with relative standard deviations between 3 to 18% in honey bees and 83 to 124% with relative standard deviations between 3 to 17% in pollen. The silica gel solid‐phase extraction cleanup method was then applied using honey bee and pollen samples that were collected from different apiaries.

AbstractThe present study investigated the accuracy of metacognitive judgments in source monitoring with self-report scales engaging either information- or experienced-based knowledge. We expected that the source monitoring abilities may be affected by the origins of meta-knowledge that underlie post-decision wagering (PDW) based on economic categorizations (experience-based scale) and confidence ratings (CR) using a conventional taxonomy of confidence (information-based scale). To examine this hypothesis, healthy participants (N = 50) performed an action memory task, in which simple actions were presented in order to be performed or imagined. In the second phase of the task, participants were required to assess source monitoring by distinguishing whether the presented action was performed or imagined. Then, the participants randomly assigned into the PDW or CR group rated their confidence in responses related to source monitoring performance. It was found that source monitoring ability is resistant to manipulation of the type of knowledge used in the scales. However, measures of metacognition indicated that accuracy of the experienced-based judgments of PDW was higher as compared to the CR scale while source monitoring. These findings suggest the origin of knowledge whose justification rests more on empirical observations generates more accurate knowledge than self-evident direct intuition with respect to discriminations of one’s own memories.
Risky financial choices in a gain and loss decision frame – the role of chronic and situationally induced time perspectives
Authors: Sekścińska Katarzyna , Rudzinska-Wojciechowska Joanna , Maison Dominika 
Published: September 2018

AbstractThe aim of the research was to explore the relationship between people’s Time Perspectives (TPs) (chronic and induced) and their propensity to take financial risks in gambling tasks with a gain and loss decision frame. The results of the study 1 (N1 = 1093) revealed that a higher chronic Present Hedonistic TP is related to a preference for unsure options in loss and gain frames, while a higher chronic Past Negative TP is related to a preference for sure options in a gain frame of financial choice, but for unsure options in a loss frame. Moreover, higher chronic Future TP is related to unsure option preference in a loss decision frame. The results of the study 2 (N2 = 563) showed that the induced Past Negative TP (in a gain frame) and Present Hedonistic TP (in both decision frames) lead to similar patterns of results to those observed for the chronic TPs.
