AbstractThe production of energy from wood biomass is as old as humanity itself. There has been enormous progress in research of sustainable pyrolysis processes for optimal energy conversion in the past 30 years. Pyrolisis–gas chromatography–mass spectrometry (PY‐GC‐MS) was used to examine the components of bark and wood of Toona sinensis for expanding high value utilization different parts of trees. In the study, 174 chemical constituents were identified in the bark; 169 chemical constituents were identified in the wood, respectively. The chemical composition of bark is different from that of wood. The change in thermal cracking 30 min ago is not very large. In the retention time is more than 30 min, they are very different. Because the ash content of bark had much large corresponding wood. Mainly the phenols and their derivatives formed after the pyrolysis of lignin and extractives. The chemical composition of T. sinensis provides a scientific basis for the development and utilization of the plant. The richer chemical constituents of T. sinensis are found, which will provide new scientific evidence for further development and utilization of bark and wood of T. sinensis.

AbstractEpoxy resin filled with suitable high Z elements can be a potential shield for X‐rays and γ‐rays. In this work, we present the γ‐ray attenuation properties of epoxy composites filled with (0–30 wt%) Tantalum pentoxide (Ta2O5) and Ta2O5‐Bi2O3, which were prepared by open mold cast technique. X‐ray diffraction patterns showed crystalline peaks of Ta2O5 and bismuth oxide (Bi2O3) in the prepared epoxy‐Ta2O5 and epoxy‐Ta2O5‐Bi2O3 composites. Homogeneity of the samples at higher filler wt% was revealed by SEM images. Mechanical characterization showed the enhanced mechanical strength of epoxy‐Ta2O5‐Bi2O3 composites compared to epoxy‐Ta2O5. Higher storage modulus and glass transition temperature of the epoxy‐Ta2O5‐Bi2O3 composites showed enhanced stiffness and thermal stability when compared to neat and epoxy‐Ta2O5. Decrease in the value of tan(δ) at higher content of filler loadings indicated the good adhesion between filler and matrix. Mass attenuation coefficients of epoxy‐Ta2O5 (30 wt%) composites at γ‐ray energies 59.54 and 662 keV were found to be 0.876 cm2 g–1 and 0.084 cm2 g–1, while that of epoxy‐Ta2O5‐Bi2O3 (30 wt% Bi2O3) composite were 1.271 cm2 g–1 and 0.088 cm2 g–1, respectively. The epoxy‐5% Ta2O5‐30% Bi2O3 composites with higher μ/ρ value and tensile strength may be a potential γ‐ray shield in various radiation environments.

AbstractIntroductionThis study describes the implementation of a mind–body intervention to reduce the perceived level of stress in a nonclinical group of university students. We used a novel approach including a single session of a mind–body technique known as the brain wave modulation (BWM) as an adjunct to a single information session on stress management.MethodsThree hundred and six students participated in the study. A quasi‐experimental design was adopted: Students in the experimental group were exposed to an information session on stress management followed by a single session of the BWM, while the other students were exposed to the information session alone.ResultsA 2 × 2 mixed factor analysis of variance demonstrated that the single session of the BWM was effective in reducing the perceived level of stress in the experimental group as compared to the control group.ConclusionThe BWM is a very easy‐to‐learn technique that presents certain advantages over traditional mind–body methods.

AbstractE‐learning, as a complex system, includes distance learning, teaching materials in various forms and shapes, group and individual learning processes, as well as interactive and tutorial work. To increase the effectiveness and efficiency of the e‐learning system, it is necessary first of all to consider the characteristics of students and their learning styles. Based on the data collected in various ways, in surveys, using the distance learning dystem (DLS) Moodle, based on the subjective assessment of the subject teachers, as well as based on data from the business information system, the student preferences are determined. Then, based on these data, an adaptation is made, a process that adapts the work of the DLS based on student knowledge. The primary goals that can be achieved through the adjustment of the e‐learning system are to improve the design and usefulness of the course, help with finding information on the course, more efficient searching and placement of search results in the context of students' interest, as well as increasing students' loyalty to a higher education institution.

AbstractColorectal cancer (CRC) is the third‐most common cancer around the world, accounting for approximately 10% of cancer‐related mortality. Deeper molecular understanding of colorectal carcinogenesis will provide evidences for identification of early diagnostic indicators and novel therapeutic strategies for CRC treatment. The p21cdc42/rac1‐activated kinase 5 (PAK5) has been reported to be involved in a variety of tumor‐promoting behaviors, whereas the underlying mechanisms of PAK5 in CRC progression are still obscure. Our current study revealed an upregulated expression of PAK5 in human CRC tissues as compared with normal adjacent biopsies, which was associated with tumor progression and metastasis. We further unraveled that inhibition of PAK5 was correlated with restrained proliferation, migration, and invasion of CRC cells in vitro and in vivo. Moreover, we showed an indispensable role of PAK5 in interacting with Cdc42 and Integrin β1, β3, thus, to facilitate the migration and invasion of CRC cells. Collectively, we pointed out a potential of PAK5 to serve as a novel therapeutic target in restricting CRC proliferation and metastasis. The uncovered mechanisms will deepen the comprehension with regard to the mechanisms of CRC progression, as well as providing new insights for therapeutic intervention in colorectal cancer.

AbstractBackgroundThere are only little data available on the comparison of clinical outcomes between a early generation drug eluting stent (eDES) and a current generation drug eluting stent (cDES) for percutaneous coronary intervention (PCI) with double stent strategy (DSS) for unprotected distal left main disease (ULMD).MethodsBetween April 2005 and December 2015, we recruited 452 consecutive ULMD patients treated with DSS (eDES, 236 patients; cDES, 216 patients). In this study, eDES included Cipher, Taxus, and Endeavor and cDES included Ultimaster, Resolute family, Xience family, Promus family, Synergy, and Nobori. The primary endpoint was target lesion failure (TLF) defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI) during the median follow‐up period of 1,809(IQR: 1,190–2,510) days.ResultsIn entire population, the rate of overall TLR was significantly lower in cDES group than that in eDES group (adjusted HR 0.62, 95% CI 0.40–0.96, p = .032). The rate of TLR for the ostium of LCX was significantly lower in cDES group than that in eDES group (adjusted HR 0.63, 95% CI 0.39–0.99, p = .047). Cardiac mortality, the rate of TLR for LM‐LAD, MI and definite/probable ST did not significantly differ between both groups. The results were preserved in the propensity adjusted population.ConclusionscDES significantly improved the clinical outcomes in population treated with DSS mainly driven by the reduction of TLR for the ostium of LCX.

AbstractBackgroundA multidisciplinary consensus document (MCD) provided a follow‐up strategy after percutaneous coronary intervention (PCI) based on individual risk profiles: A, high; B, intermediate; and C, low.AimTo assess patterns of follow‐up after PCI and to evaluate the potential reduction of cardiologic examinations with the application of the MCD.MethodsThe post‐PCI registry was carried out at 31 Italian Hospitals and included consecutive patients undergoing PCI. We collected cardiologic consults (CC), noninvasive stress tests (ST), and echocardiograms (EC) actually performed at 12 months and we compared them with the expected by the MCD.ResultsWe included 1,113 patients (58% with acute coronary syndrome) that underwent 1,567 CC, 398 ST, and 612 EC. The performed CC and ST were significantly lower compared to the expected, respectively [1.6 (95% CI, 1.5–1.7) vs. 1.9 (95% CI, 1.8–2.0), and 0.40 (95% CI, 0.4–0.5) vs. 0.61 (95% CI, 0.6–0.7), p < .001]; the performed EC were significantly higher [0.6 (95% CI, 0.6–0.7) vs. 0.3 (95% CI, 0.3–0.37), p < .001]. Patients at moderate low risk had an excess of noninvasive tests whereas patients at higher risk received less examinations than the expected.The individual risk profile was an independent predictor of increased number of cardiac examination in patients at intermediate and low risk [profile B, OR 2.56 (95%CI 1.38–4.75); profile C, OR 27.00 (95%CI 8.13–89.62), p < .001].ConclusionIn real world patients undergoing PCI, the intensity of follow‐up at 12 months appeared not based on individual risk profile, with a higher numbers of examinations, particularly EC, performed in low risk subjects.

Published: May 2020

AbstractProcess controls for mesophilic dark fermentation using a pH‐dependent feeding strategy without NaOH addition were examined. One reactor utilizing microorganism holdback and two continuously stirred‐tank reactors (CSTRs) with the same volume were employed. These were fed with pig manure and glucose as cosubstrates. Different hydraulic retention times were applied. The target pH was 5.5 within a limited range and controlled by varying organic loading rate. When the pH target interval was exceeded, the hydrogen production rate (HPR) decreased, and CH4 was produced. A pH below the target interval had positive effects on the HPR.

Published: May 2020

AbstractActivated carbon (AC) was gained from Pinus montezumae (PM) wood sawdust and chemical activation with K2CO3 was used for obtaining activated carbons. Variations in reaction conditions such as temperature, impregnation ratio (IR), and activation time were carried out to study their influence on the specific surface area (SSA) and average pore volume (APV) in AC. Materials were analyzed by means of Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X‐ray diffraction (XRD) to determine the functional groups, pore structure, and morphology of pine sawdust and activated carbons. Activated carbons were amorphous in nature with some crystalline regions.

AbstractNovel chiral selectors based on 3,5‐dimethyl phenylcarbamoylated β‐cyclodextrin connecting quinine (QN) or quinidine (QD) moiety were synthesized and immobilized on silica gel. Their chromatographic performances were investigated by comparing to the 3,5‐dimethyl phenylcarbamoylated β‐cyclodextrin (β‐CD) chiral stationary phase (CSP) and 9‐O‐(tert‐butylcarbamoyl)‐QN‐based CSP (QN‐AX). Fmoc‐protected amino acids, chiral drug cloprostenol (which has been successfully employed in veterinary medicine), and neutral chiral analytes were evaluated on CSPs, and the results showed that the novel CSPs characterized as both enantioseparation capabilities of CD‐based CSP and QN/QD‐based CSPs have broader application range than β‐CD‐based CSP or QN/QD‐based CSPs. It was found that QN/QD moieties play a dominant role in the overall enantioseparation process of Fmoc‐amino acids accompanied by the synergistic effect of β‐CD moiety, which lead to the different enantioseparation of β‐CD‐QN‐based CSP and β‐CD‐QD‐based CSP. Furthermore, new CSPs retain extraordinary enantioseparation of cyclodextrin‐based CSP for some neutral analytes on normal phase and even exhibit better enantioseparation than the corresponding β‐CD‐based CSP for certain samples.

Published: May 2020

AbstractThis work deals with the catalytic performance of nickel‐cobalt supported on ceria‐doped gadolinia (GDC) catalyst in the single and in the simultaneous methanation of carbon monoxide and carbon dioxide. The catalysts have been prepared by impregnation method, starting from metal salts precursors. Samples have been characterized by x‐ray diffraction (XRD), thermogravimetric analysis and differential scanning calorimetry (TGA‐DSC), hydrogen temperature programmed reduction (TPR‐H2), transmission electronic microscopy (TEM), and scanning electron microscopy (SEM/EDX) technique. The temperature examined for methanation tests ranged from 200°C‐600°C. The results show that the prepared and optimized catalysts possess the main characteristics of materials suitable for SOECs (solid oxide electrolyzer cells) applications: high metal content (50% wt/wt with respect to the support), high activity, and high stability. The catalytic performance of bimetallic catalysts highlights that the cobalt does not improve the activity of the nickel catalysts.

Published: May 2020

AbstractThe intrinsic properties of tetrazine as a π‐anion receptor and as an on/off recognition probe merged with H‐bond ability of an urea motif into a single architecture constitutes a new generation of well‐defined anion receptors. Complexation properties directly benefit from the dual and synergistic contribution of tetrazine and urea. In this study, we report on the synthesis and assessment of binding properties to anions of diverse geometries. Association constants have been predicted by theoretical calculations and evaluated by multiple and complementary experimental techniques including electrospray‐mass tandem spectroscopy, NMR, UV‐visible, steady state fluorescence spectroscopies and time resolved fluorescence. These results provide the basis for a better understanding of both the complexation and the anion‐dependent quenching mechanism.

AbstractObjectiveThe coronavirus pandemic has led to a dramatically different way of working for many therapists working with eating disorders, where telehealth has suddenly become the norm. However, many clinicians feel ill equipped to deliver therapy via telehealth, while adhering to evidence‐based interventions. This article draws together clinician experiences of the issues that should be attended to, and how to address them within a telehealth framework.MethodSeventy clinical colleagues of the authors were emailed and invited to share their concerns online about how to deliver cognitive‐behavioral therapy for eating disorders (CBT‐ED) via telehealth, and how to adapt clinical practice to deal with the problems that they and others had encountered. After 96 hr, all the suggestions that had been shared by 22 clinicians were collated to provide timely advice for other clinicians.ResultsA range of themes emerged from the online discussion. A large proportion were general clinical and practical domains (patient and therapist concerns about telehealth; technical issues in implementing telehealth; changes in the environment), but there were also specific considerations and clinical recommendations about the delivery of CBT‐ED methods.DiscussionThrough interaction and sharing of ideas, clinicians across the world produced a substantial number of recommendations about how to use telehealth to work with people with eating disorders while remaining on track with evidence‐based practice. These are shared to assist clinicians over the period of changed practice.
Stuck on pain? Assessing children’s vigilance and awareness of pain sensations
Authors: Heathcote Lauren C. , Simons Laura E. 
Published: May 2020

AbstractBackgroundAttending towards pain is proposed as a key mechanism influencing the experience and chronification of pain. Persistent attention towards pain is proposed to drive poor outcomes in both adults and children with chronic pain. However, there are no validated self‐report measures of pain‐related attention for children.MethodsThe goals of this study were to adapt the Pain Vigilance and Awareness Questionnaire (PVAQ) for use in a child sample, to preliminary examine its psychometric properties, and to assess its utility over and above a measure of general attentional capacities. We adapted the language of the PVAQ to be more easily understood by children as young as 8 years. In a sample of 160 children (8–18 years) with chronic pain, we examined the factor structure, internal consistency and criterion validity of the PVAQ‐C.ResultsThe PVAQ‐C demonstrated excellent internal consistency (α = 0.92) and moderate‐to‐strong criterion validity. A one‐factor structure best fit the data. Children who reported greater attention to pain also reported greater pain catastrophizing, fear of pain, avoidance of activities and poorer physical functioning. Pain‐related attention remained a significant predictor of functioning while controlling for demographics, catastrophizing and fear‐avoidance. Pain‐related attention also significantly predicted child outcomes independent of the child's general attention control capacities, indicating added value of a pain‐specific measure of attention.ConclusionsThe PVAQ‐C shows strong indices of internal reliability and criterion validity, and indicates unique predictive utility. It will be important to study the role of pain‐related attention in youth within developmental and functional–motivational frameworks.SignificancePain‐related attention is proposed as a key factor influencing fear‐avoidance outcomes in both adults and youth with chronic pain, yet no self‐report measures of pain‐related attention have been validated for children. This paper presents a child version of the Pain Vigilance and Awareness Questionnaire (PVAQ‐C), which indicates strong internal consistency, criterion validity and unique predictive validity, and provides evidence to support the Fear‐Avoidance Model in youth with chronic pain.
