Enhancement of CaO‐based sorbent for CO2 capture through doping with seawater
Authors: González Belén , Kokot‐Blamey John , Fennell Paul 
Published: June 2020

AbstractLimestone can be used to generate a sorbent suitable for CO2 capture via the reversible carbonation of CaO, in a process often referred to as calcium looping. This sorbent loses reactivity to CO2 upon cycles of carbonation and calcination (the reverse of carbonation). Several methods of improving sorbent performance have previously been investigated, including by generating synthetic sorbents or simple doping. Here, we demonstrate, for the first time, that sorbent performance can be enhanced by simple doping with seawater. This effect is consistent across five different limestones investigated and can be enhanced by steam addition. This would be a simple and inexpensive method for improving sorbent performance in calcium looping processes. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.
Comparison of hydroxide‐based adsorbents of Mg(OH)2 and Ca(OH)2 for CO2 capture: utilization of response surface methodology, kinetic, and isotherm modeling
Authors: Ghaemi Ahad , Behroozi Amir Hossein 
Published: June 2020

AbstractCO2 capture using hydroxide‐based adsorbents is studied experimentally for two adsorbents of Mg(OH)2 and Ca(OH)2. The adsorbents are characterized before and after the adsorption process by X‐ray diffraction and Fourier transform infrared spectroscopy analyses. The experiments were carried out in the ranges of 25–65°C, 2–10 bar, and 0.5–2.5 g for temperature, initial pressure, and weight of adsorbent, respectively. Based on the response surface methodology with a central composite design approach, predicted CO2 adsorption capacities are fitted well with R2 values of 0.981 and 0.929 for Mg(OH)2 and Ca(OH)2, respectively. The Freundlich isotherm model with R2 values of 0.985 and 0.994 is the best model for adsorption capacity prediction of Mg(OH)2 and Ca(OH)2, respectively. Also, the pseudo‐second‐order kinetic model with R2 values more than 0.98 is selected as the best model for both adsorbents. From the thermodynamic parameters, the reactive adsorption process is found to be exothermic and spontaneous. Due to higher adsorption percentage and capacity at the same conditions, Ca(OH)2 is more efficient than Mg(OH)2 for CO2 capture at studied ranges. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.

Background and Aims
The development and progression of hepatocellular carcinoma (HCC) is dependent on its local microenvironment. Tumor‐associated macrophages (TAMs) are deemed a key factor for the tumor microenvironment and attribute to contribute to tumor aggressiveness. However, the detailed mechanism underlying the pro‐metastatic effect of TAMs on HCC remains undefined.

Approach and Results
The present study proved that TAMs were enriched in HCC. TAMs were characterized by an M2‐polarized phenotype and accelerated the migratory potential of HCC cells in vitro and in vivo. Furthermore, we found that M2‐derived exosomes induced TAM‐mediated pro‐migratory activity. With the use of mass spectrometry, we identified that integrin, αMβ2 (CD11b/CD18), was notably specific and efficient in M2 macrophage–derived exosomes (M2 exos). Blocking either CD11b and/or CD18 elicited a significant decrease in M2 exos–mediated HCC cell metastasis. Mechanistically, M2 exos mediated an intercellular transfer of the CD11b/CD18, activating the matrix metalloproteinase‐9 signaling pathway in recipient HCC cells to support tumor migration.

Conclusions
Collectively, the exosome‐mediated transfer of functional CD11b/CD18 protein from TAMs to tumor cells may have the potency to boost the migratory potential of HCC cells, thus providing insights into the mechanism of tumor metastasis.

AbstractFirst line therapy of patients with marginal zone lymphomas (MZL) is not well established and various regimens with chemo‐immunotherapy can be used. Rituximab plus bendamustine (BR) is an effective and manageable treatment option for patients affected by indolent non‐Hodgkin lymphoma. The aim of this monocentric retrospective study was to analyze the effectiveness and safety of the use of BR regimen in MZL patients in first line in daily clinical practice. The treatment schedule was rituximab at the dose of 375 mg/m2 on day 1 of each cycle and bendamustine at the dose of 90 mg/m2 on day 2 and 3, every 28 days for a maximum of 6 cycles. We analyzed 65 MZL patients (28 extranodal [EMZL], 23 splenic [SMZL], and 14 nodal [NMZL]) who underwent BR regimen as first line treatment. The median time from diagnosis to therapy was 2.5 months. Final responses were: 38 complete response (CR, 58.5%), 20 partial response and 7 progressive disease, leading to an overall response rate (ORR) of 89.2%. With respect to the histology, the ORR was 89.3% for EMZL, 82.6% for SMZL and 100% for NMZL, respectively (difference not statistically significant). With a median follow‐up time of 44.6 months (range, 3.3‐175.0 months), 2 (one EMZL after 42 months and one SMZL after 10 months) of 38 (5.2%) CR patients had disease relapse, yielding an estimated disease free survival of 89.2% at 61.1 months. The estimated 6‐year progression free survival was 71.8% with 15 relapsed/progressed patients showing lymphoma recurrence within 48 months from end of treatment. The most frequently reported adverse events (any grade) were neutropenia (N = 35, 53.8%), fatigue (N = 15, 23.0%), and nausea (N = 12, 18.4%). All toxicities quickly resolved and no treatment‐related death occurred. The BR regimen is effective and feasible in MZL patients inducing prolonged disease control with manageable toxicities.

AbstractIssue addressedGrowing evidence suggests that public parks enable physically active communities; however, little is known of the impact of council‐provided exercise facilities in outdoor green spaces, and the challenges of providing this infrastructure at a local level. This paper sought to describe some of the factors, as perceived by local government area (LGA) council representatives within Queensland, Australia, that influence community use of, as well as council provision for, weight‐bearing outdoor fitness station infrastructure in public parks.MethodsA nested mixed‐methods study was employed, comprised of a survey sent to council representatives for all 78 Queensland LGAs (Stage 1), and follow‐up interviews to elicit further insights into the provision of infrastructure in public parks (Stage 2; n = 7). Perceptions around participants’ corporate role in the provision of outdoor fitness stations were the focus of analyses.FindingsA thematic analysis described themes of: Moderating public attitudes and motivation; The flow of information; Supporting an active community; Return on investment; and Safety, complianceand climate. Provision of equipment was influenced by the perception that it represented poor value for money, in terms of the desired outcome of increased physical activity, especially when compared with other types of infrastructure (particularly, walking trails); however, opinions about this lack of use outdoor exercise equipment were most often based on anecdotal evidence.ConclusionsCouncils are motivated to support active communities. They would benefit from better access to information about park usage, strategies for marketing healthy living initiatives and data about the economic benefits of parks.So what?The current study explores the perspectives of LGA professional “gatekeepers,” who develop and maintain public physical activity facilities. Their insights are essential to better understand the practicalities of delivering desirable urban green spaces for physically active communities.
Statistical analysis of stagnation‐point heat flow in Williamson fluid with viscous dissipation and exponential heat source effects

Published: June 2020

AbstractThis analysis explores the effect of the novel exponential space‐dependent heat generation factor on the stagnation‐point Williamson fluid flow over a stretchable surface. The heat transport phenomenon is carried out by the addition of viscous and Ohmic dissipations. Similarity transformations are applied to the nonlinear system of partial differential expressions that arise by the flow. The nonlinear ordinary differential system hence obtained is solved to visualize the role of different constraints graphically. Statistical methods such as correlation, probable error, and regression are utilized. The probable error is evaluated to calculate the reliability of the computed correlation factors. The study reveals that the velocity phenomenon is reduced by incrementing the Weissenberg parameter. The velocity of the hydromagnetic liquid is lesser than the velocity of magnetohydrodynamic fluid flow. Also, the higher heat generation factor gives a boost to the temperature of the flowing material.

ABSTRACTThe purpose of this study was to examine the moderating role of maternal sensitivity on the association between prenatal adversity and externalizing behaviors at 24 months of age in a diverse, high‐risk sample. We hypothesized that among children with higher prenatal adversity, high maternal sensitivity would serve as a protective factor. Participants were 247 primarily low‐income, diverse dyads. Results indicated a significant interaction effect of maternal sensitivity and prenatal adversity on externalizing problems. The association between prenatal adversity and externalizing behaviors was significant only among children who experienced low prenatal adversity, with higher maternal sensitivity associated with lower externalizing behaviors. These findings indicate that, in the absence of high prenatal risk, responsive and sensitive parenting can buffer children in an otherwise high‐risk sample from the development of externalizing behaviors.

AbstractBackgroundThe detection of serum antibodies to the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is emerging as a new tool for the coronavirus disease 2019 (COVID‐19) diagnosis. Since many coronaviruses are sensitive to heat, heating inactivation of samples at 56°C prior to testing is considered a possible method to reduce the risk of transmission, but the effect of heating on the measurement of SARS‐CoV‐2 antibodies is still unclear.MethodsBy comparing the levels of SARS‐CoV‐2 antibodies before and after heat inactivation of serum at 56°C for 30 minutes using a quantitative fluorescence immunochromatographic assayResultsWe showed that heat inactivation significantly interferes with the levels of antibodies to SARS‐CoV‐2. The IgM levels of all the 34 serum samples (100%) from COVID‐19 patients decreased by an average level of 53.56%. The IgG levels were decreased in 22 of 34 samples (64.71%) by an average level of 49.54%. Similar changes can also be observed in the non–COVID‐19 disease group (n = 9). Of note, 44.12% of the detected IgM levels were dropped below the cutoff value after heating, suggesting heat inactivation can lead to false‐negative results of these samples.ConclusionOur results indicate that heat inactivation of serum at 56°C for 30 minutes interferes with the immunoanalysis of antibodies to SARS‐CoV‐2. Heat inactivation prior to immunoanalysis is not recommended, and the possibility of false‐negative results should be considered if the sample was pre‐inactivated by heating.

AbstractBackgroundThe use of matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry is gradually spreading among large‐scale laboratories; however, this method is impractical for small‐scale laboratories. In laboratories without access to these rapid identification methods, problems related to them remain unsolved. In this study, we aimed to develop a rapid and inexpensive method to presumptively identify Enterobacterales using CHROMagar Orientation medium.MethodsThe algorithm for presumptive identification of Enterobacteriaceae using CHROMagar Orientation medium was based on our previous studies. Modified property tests for indole, lysine decarboxylase, ornithine decarboxylase, and hydrogen sulfide were performed to evaluate the differentiation of the bacterial species.ResultsUsing the type strains and clinical isolates, it was possible to conduct the property tests at a low cost, within 4 hours. The spot indole test was performed without any nonspecific reactions for the bacteria forming colored colonies. The presumptive identification of bacteria was thereby possible within 24 hours after specimen submission.ConclusionAll these results suggest that the rapid presumptive identification of Enterobacterales is possible with this new identification method using CHROMagar Orientation medium. This is therefore a prompt and economical method that can be used in routine laboratory work.

Authors: Johnson, Gary M. , Stein, Amy B. , Fitzgerald, Nancy M. , Copeland Cara C. , Velazquez Daphne M. , Trowbridge Tatiyana 
Published: June 2020

AbstractContextPreclinical dental school instructors often observe some first‐year students develop hand skills required for dental procedures more quickly and more easily than their peers. When questioned regarding prior experience, these advanced students often participated in physical activities that seem to predispose them to adapt their previously learned psychomotor hand skills to those required for dentistry.ObjectiveThis study examines the results of an Institutional Review Board approved 22‐question survey of various lifelong predental school activities and correlations to first‐year and second‐year simulation clinic practical exam performance.DesignThe survey was taken anonymously at the Midwestern University College of Dental Medicine‐Arizona by 4 consecutive dental school classes of 2017–2020 composed of 560 students, 552 of which responded. The purpose was to discover associations between lifelong activities and practical exam scores that may act as predictors of preclinical ability to develop visualization and psychomotor hand skills required for dental procedures.ResultsHigher preclinical practical scores were found to have the most correlation with higher levels of participation in psychomotor, artistic and outdoor physical activities. Participation in computer, musical instrument and culinary activities had no significant correlation, and prior experience in the medical or dental field had a negative correlation.ConclusionThe lack of participation in these predisposing lifelong activities may predict slower development of dental hand skills and signal the need for more hands‐on tutorial instruction in the simulation clinic so these students do not lag behind their peers.
Hamiltonicity, pancyclicity, and full cycle extendability in multipartite tournaments
Authors: Zhang Zan‐Bo , Zhang Xiaoyan , Gutin Gregory , Lou Dingjun 
Published: June 2020

AbstractA digraph with vertices is Hamiltonian (pancyclic and vertex‐pancyclic, respectively) if contains a Hamilton cycle (a cycle of every length , for every vertex , a cycle of every length through , respectively.) It is well‐known that a strongly connected tournament is Hamiltonian, pancyclic, and vertex pancyclic. A digraph is cycle extendable if for every non‐Hamiltonian cycle of , there is a cycle such that contains all vertices of plus another vertex of . A cycle extendable digraph is fully cycle extendable if for every vertex , there exists a cycle of length 3 through . Note that full cycle extendability is a stronger property than vertex pancyclicity. While it is well‐known that every strongly connected tournament is vertex pancyclic, Hendry showed that not every strongly connected tournament is fully cycle extendable and characterized an infinite class of strongly connected tournaments, which are not fully cycle extendable. A ‐partite tournament is an orientation of a ‐partite complete graph (for , it is called a bipartite tournament). Gutin and later Häggkvist and Manoussakis characterized Hamiltonian bipartite tournaments. A bipartite digraph with vertices is even pancyclic (even vertex pancyclic, respectively) if contains a cycle of every even length (a cycle of every even length through for every , respectively). Beineke and Little, and Zhang proved that every bipartite tournament is even pancyclic and even vertex pancyclic, respectively, if and only if it is Hamiltonian and does not belong to a well‐defined infinite class of regular bipartite tournaments. We prove that unlike in the case of tournaments, every even pancyclic bipartite tournament is fully cycle extendable. We show that this result cannot be extended to ‐partite tournaments for any fixed (where we naturally replace even vertex pancyclicity by vertex pancyclicity).

Published: June 2020

AbstractWe introduce a list‐coloring extension of classical Ramsey numbers. We investigate when the two Ramsey numbers are equal, and in general, how far apart they can be from each other. We find graph sequences where the two are equal and where they are far apart. For ‐uniform cliques we prove that the list Ramsey number is bounded by an exponential function, while it is well known that the Ramsey number is superexponential for uniformity at least 3. This is in great contrast to the graph case where we cannot even decide the question of equality for cliques.

Authors: Moshref Razavi Habib , Covello Thomas 
Published: June 2020

AbstractThe case of an 83‐year old male patient is described. He presented to our hospital with a 2 week history of intermittent syncope and was diagnosed with atrial fibrillation. His CBC showed bicytopenia with anemia and neutropenia in context of a leucoerythroblastic blood film and blastemia. As the patient was previously diagnosed with stage IV diffuse large B cell lymphoma; treated with CHOP‐R a bone marrow biopsy was requested to rule out acute leukemia. A cellular bone marrow aspirate showed presence of a myeloblast infiltrate (32.6%; confirmed by flow cytometry). Interestingly blast phagocytosis of terminally differentiated cells along with cannibalism of other blasts was identified. The diagnosis of therapy‐related acute myeloid leukemia was reached and a palliative consultation was requested. To our knowledge, this is the first report of blast cytophagocytosis and cannibalism associated with a therapy‐related acute myeloid leukemia with a complex karyotype.
Seeking double personality: Nakamura Kokyō's work in abnormal psychology in early 20th‐century Japan
Authors: Wu Yu‐chuan 
Published: June 2020

AbstractThis paper examines Nakamura Kokyō's study of a woman with a split personality who lived in his home as a maid from 1917 until her death in 1940. She was his indispensable muse and assistant in his efforts to promote abnormal psychology and psychotherapy. This paper first explores the central position of multiple personality in Nakamura's theory of the subconscious, which was largely based on the model of dissociation. It then examines how it became a central issue in Nakamura's disputes with religions including the element of spirit possession, which invoked Western psychical research to modernize their doctrines. While both were concerned with the subconscious and alterations in personality, Nakamura's psychological view was distinguished from those spiritual understandings by his emphasis on individual memories, particularly those that were traumatic, and hysteria. The remaining sections of the paper will examine Nakamura's views on memory and hysteria, which conflicted with both the academic mainstream and the established cultural beliefs. This conflict may partly explain the limited success of Nakamura's academic and social campaigns.
