Analysis of turfgrass research papers 2008–2019: Implications and future opportunities for the International Turfgrass Society
Authors: Loch Donald S. 
Published: May 2022

AbstractThe content of 1,626 turfgrass papers published in the quadrennial International Turfgrass Society Research Journal (ITSRJ), 17 multi‐issue annual journals, and ad hoc volumes of Acta Horticulturae over 12 yr (2008 to 2019) was divided into three categories: cool‐season turfgrasses, warm‐season turfgrasses, and other topics (both cool‐ and warm‐season turfgrasses and/or more general topics) and compared together with the most recent Journal Impact Factors. Overall, there were approximately 50% cool‐season, 40% warm‐season, and just under 10% more general papers. The ITSRJ (along with HortScience) most closely aligned with this overall pattern compared with the other 17 journals which published higher or lower proportions in these topic categories. While no one journal dominated the international turfgrass literature over the period surveyed, ITSRJ (one of only two non‐Impact Factor journals surveyed) was the only one that contributed >25% of the published papers. Implications and future opportunities for the International Turfgrass Society are explored in relation to better meeting the needs of academic research members for an Impact Factor journal while at the same time broadening the membership base through practitioners and other users attracted by the Society's major asset of turfgrass information.

AbstractObjectiveTo identify differentially expressed lncRNA, miRNA, and mRNA during the pathogenesis of gout, explore the ceRNA network regulatory mechanism of gout, and seek potential therapeutic targets.MethodFirst, gout‐related chips were retrieved by GEO database. Then, the analysis of differentially expressed lncRNAs and mRNAs was conducted by R language and other software. Besides, miRNA and its regulated mRNA were predicted based on public databases, the intersection of differentially expressed mRNA and predicated mRNA was taken, and the lncRNA‐miRNA‐mRNA regulatory relationships were obtained to construct the ceRNA regulatory network. Subsequently, hub genes were screened by the STRING database and Cytoscape software. Then the DAVID database was used to illustrate the gene functions and related pathways of hub genes and to mine key ceRNA networks.ResultsThree hundred and eighty‐eight lncRNAs and 758 mRNAs were identified with significant differential expression in gout patient, which regulates hub genes in the ceRNA network, such as JUN, FOS, PTGS2, NR4A2, and TNFAIP3. In the ceRNA network, lncRNA competes with mRNA for miRNA, thus affecting the IL‐17 signaling pathway, TNF signaling pathway, Oxytocin signaling pathway, and NF‐κB signaling pathway through regulating the cell's response to chemical stress. The research indicates that five miRNAs (miR‐429, miR‐137, miR‐139‐5p, miR‐217, miR‐23b‐3p) and five lncRNAs (SNHG1, FAM182A, SPAG5‐AS1, HNF1A‐AS1, UCA1) play an important role in the formation and development of gout.ConclusionThe interaction in the ceRNA network can affect the formation and development of gout by regulating the body's inflammatory response as well as proliferation, differentiation, and apoptosis of chondrocytes and osteoclasts. The identification of potential therapeutic targets and signaling pathways through ceRNA network can provide a reference for further research on the pathogenesis of gout.

Published: May 2022

AbstractBACKGROUNDA novel chelating membrane was fabricated for removing simultaneously metal ions (Cd2+, Pb2+ and Cu2+) and proteins (bovine serum albumin and lysozyme) from simulated industrial effluent. The purpose of the study was to investigate the influence of pollutant concentration on the separation efficiency of the chelating membrane for pollutants.RESULTS(i) The removal of metal ions mainly relies on the adsorption capacity of the chelating membrane, and seems to be independent of the concentration of protein. (ii) The retention of proteins depends mainly on their concentration in solution. (iii) When the wastewater contains high concentration of metal ions (C = 100 mg L−1) and low concentration of proteins (C = 10 mg L−1), the chelating membrane exhibits overall poor separation performance, with a low ion removal efficiency (55–70%) and a low protein rejection rate (ca 60%). (iv) When the wastewater contains low concentration of metal ions (C = 10 mg L−1) and high concentration of proteins (C = 100 mg L−1), the chelating membrane exhibits overall excellent separation performance, with ion removal rates of higher than 90% (except for Cd2+) and protein rejection rates of higher than 90%.CONCLUSIONSThe separation efficiency of the chelating membrane for metallic and organic pollutants greatly depends on the pollutant concentration in the wastewater. This study provides a theoretical basis for membrane technology for removing simultaneously heavy metals and organic pollutants in wastewater. © 2022 Society of Chemical Industry (SCI).

Published: May 2022

AbstractBACKGROUNDOn the way to convert biomass‐derived products as a renewable and environment‐friendly source to high‐value added chemicals, one great challenge is the effective control of selectivity in the reaction. Here, we contribute a heterogeneous catalysis method for selective transformation of biomass‐based 5‐hydroxymethylfurfural (HMF) into 2,5‐diformylfuran (DFF) via multicomponent bismuth molybdate catalyst. The influence of the different pH value on the catalytic activity of the catalyst were investigated. In addition, to evaluate the catalytic performance of the catalyst in the selective oxidation of HMF, a variety of important reaction parameters such as the reaction temperature, catalyst amount, atmosphere, and solvent were examined.RESULTSThe catalyst prepared with pH value in the range of 1–2 exhibits the optimal catalytic activity in the selective aerobic oxidation of the hydroxy group of HMF. As a result, the target compound of DFF could be obtained with excellent yield (99%) and high selectivity (> 99%) in the presence of 0.25 mg Co9Fe3BiMo12O51 (pH = 1–2) in DMSO at 130 °C under O2 atmosphere. In addition, the catalyst Co9Fe3BiMo12O51 could be reused several times without a significant loss of its catalytic activity.CONCLUSIONIn this work, a heterogeneous catalytic approach to oxidizing HMF to DFF using Co9Fe3BiMo12O51 as catalyst and molecular oxygen as oxidant was established. The O2 temperature‐programmed desorption (O2‐TPD) characterization indicated that the pH value of co‐precipitation obviously affected the oxygen mobility and storage capacities in the catalysts, which is related to the catalytic performance in the selective aerobic oxidation. © 2022 Society of Chemical Industry (SCI).

Published: May 2022

AbstractBACKGROUNDThe composite photocatalyst Ag‐Mn/NS‐HNbMoO6 was prepared by exfoliation‐recombination method, and applied for adsorption and conversion of ethyl mercaptan.RESULTSThe results showed that the interfacial charges could be transferred during the composite process because of the difference of the Sanderson electronegativity of Ag, Mn and H. The adsorbing capacity of the Ag‐Mn/NS‐HNbMoO6 is 222.7 μmol·g−1 which is more than 4 times as much as the adsorbing capacity of HNbMoO6 nanosheet duo to the hydrogen bond interaction and Ag–S interaction. Ethyl mercaptan could be photocatalytic converted in the deepest to sulfates on the Ag‐Mn/NS‐HNbMoO6 because of the strongest photocatalytic performance.CONCLUSIONSAg‐Mn/NS‐HNbMoO6 composite is a high‐performance photocatalytic conversion desulfurization catalyst with a strong adsorptive‐oxidative‐photocatalytic performance. © 2022 Society of Chemical Industry (SCI).

AbstractBACKGROUNDThis study focuses on the removal of gaseous pollutants by nanogold–silver (Au–Ag)‐, nanosilver‐ and chitosan‐coated activated carbon filters. Target gaseous pollutants included formaldehyde (HCHO), acetone (CH3COCH3), carbon monoxide (CO) and bioaerosol.RESULTSLaboratory experimental results show that chitosan‐coated filters are 16.33% more efficient than uncoated carbon filters when challenged with HCHO, but the same gain is not observed when challenged with CH3COCH3 and CO. When challenged with HCHO and CO, the removal efficiency of Au–Ag‐coated carbon was found to be 20% and 7.11% higher than that of uncoated carbon, respectively. A parking lot field study to determine the efficiency of Au–Ag‐coated carbon when challenged with CO and bacteria concluded that the removal efficiency of Au–Ag‐coated carbon was 7.48% and 19.57% higher, respectively, than that of uncoated carbon. The removal efficiencies for bacteria and fungi were increased 35% and 17.1% when the carbon filter was coated with chitosan, respectively. At a kindergarten, the removal efficiency for HCHO was assessed, which was increased 9.02% and 42% when the carbon filter was coated with Au–Ag and chitosan, respectively.CONCLUSIONSLaboratory experimental data were evaluated using pseudo‐first‐order and pseudo‐second‐order kinetic equations. Pseudo‐second‐order kinetics were found to be applicable to discuss the adsorption kinetics. The overall rate of the Au–Ag‐, nanosilver‐ and chitosan‐coated activated carbon filter adsorption process appears to be influenced by more than one step of the intraparticle diffusion model. © 2022 Society of Chemical Industry (SCI).

AbstractBACKGROUNDBiological aerated filter (BAF) is an efficient and economical treatment process to cope with the rapid increasing drainage of aquaculture wastewater. Here, GAC and ceramic, which have the combination advantage, was used as filters of BAF system to treat the aquaculture wastewater. The effect of filters in different sequences was also compared. The BAF with GAC at the bottom is named as GAC‐down BAF, and the BAF at the top is named as GAC‐upper BAF.RESULTSResults showed that the removal efficiency of total nitrogen (TN) in GAC‐down BAF was 54.2 ± 1.2% higher than that in GAC‐upper BAF, when the HRT was 3 h and the gas‐water ratio was 5:1. Additionally, it had better phosphorus and COD removal performance in the GAC‐down BAF than those in the GAC‐upper BAF. Microbial community analysis of biofilm attached to different filter layers indicated that the abundances of functional microorganisms like Zoogloea spp., Acinetobacter spp., Pseudomonas spp., Nitrospira spp. on GAC of the GAC‐down BAF were higher than those attached to ceramsite at the same site of GAC‐up BAF.CONCLUSIONIt was demonstrated that GAC could provide a suitable niche for the growth of functional microbes at the up‐flow BAF system, and plays a key role in pollutant removals from aquaculture wastewater. © 2022 Society of Chemical Industry.

AbstractBACKGROUNDA main advantage of microalgae cultivation is its capacity to produce metabolites of biotechnological interest through modification of growth conditions. The aim was to evaluate the effect of strontium addition (Sr) to the culture medium and culture scale‐up of Tetraselmis suecica on antioxidant capacity and antiangiogenic activity.RESULTSAntiradical activity in extracts through the DPPH (α, α‐diphenyl‐β‐picrylhydrazyl free radical) scavenging method was higher for a 5‐L reactor (81.9 ± 2.5%) than for a 80‐L reactor (60 ± 4.6%), and through the TEAC (Trolox equivalent antioxidant capacity) method, the activity measures were 1.38 ± 0.05 and 1.12 ± 0.05 mmol Trolox, respectively. Lipid peroxidation β‐carotene bleaching reached the highest activity coefficients for the 80‐L reactor (ethanol extract 724 ± 35 AAC). Antioxidant activity was similar with and without Sr, although it was affected by the scale‐up. Extractable solids were maximized in the 80‐L reactor (350 ± 6 mg g−1 for methanol–water), whereas phenolic compounds were higher for ethanol extracts (5.5 ± 0.1 mg GAE g−1 for 5‐ and 80‐L reactors, without Sr addition). The antiangiogenic activity was improved in the methanol extract by ≈50% more than the negative control.CONCLUSIONThe antioxidant activity of T. suecica biomass can be improved using different culture scale‐ups and solvents during extraction, increasing the production of natural sources of antioxidant and antiangiogenic compounds for their use in food, health and cosmetics. © 2022 Society of Chemical Industry (SCI).

AbstractBACKGROUNDEfficient pretreatment is key to improving landfill leachate biodegradability. This is the first study to combine hydrodynamic cavitation (HC) and potassium ferrate (K2FeO4) for the treatment of landfill leachate, using chemical oxygen demand (COD) and UV absorbance at a wavelength of 254 nm (UV254) as the main test indicators. The feasibility of HC combined with K2FeO4 as a mature leachate pretreatment method was explored.RESULTSThe HC experiment used 40 L of mature landfill leachate raw water, with optimal reaction conditions of: pH 4, 70 min continuous cavitation and K2FeO4 dosage of 1.5 g/L. The leachate COD decreased from 3812.64 mg/L to 1833.8 mg/L (51.69% removal), while UV254 decreased from 20.44 to 6.14 (65.14% removal) and total organic carbon decreased from 1489 to 915.3 mg/L (38.53% removal). After HC/K2FeO4 treatment, the biochemical oxygen demand after 5 days (BOD5)/COD (0.61) was greatly improved compared to the raw leachate (0.362), with effluent reaching the standard (BOD5/COD >0.6) required to be considered fully biodegradable. Studies have shown that HC can accelerate the reaction rate of Fe(VI) with pollutants, while also forming a Fenton‐like system with the products of Fe(VI) reduction. FT‐IR analysis results showed that HC/K2FeO4 treatment achieved the removal of complex high molecular weight compounds, by carbonization or decomposition into more biodegradable substances.CONCLUSIONCompared with the traditional pretreatment process, HC/K2FeO4 exhibits strong oxidation and coagulation performance, achieving the significant removal of leachate humus and effectively improving biodegradability, while also being suitable for large‐scale applications, such as landfill leachate treatment. © 2022 Society of Chemical Industry (SCI).

AbstractPurposeTo determine the long‐term fetal cardiac effects of the SARS‐CoV‐2 infection in pregnant women recovered from moderate COVID‐19 with fetal echocardiography (ECHO).MethodsForty‐five pregnant women that recovered from moderate COVID‐19 (CRG) 4 weeks after the infection confirmation, were compared with 45 gestational and maternal age‐matched control groups (CG) in terms of demographic features fetal cardiac morphological (sphericity index, cardiothoracic ratio), and functional (myocardial performance index, mitral E/A, tricuspid E/A, mitral and tricuspid annular plane systolic excursion) parameters.ResultsThere was no difference in demographic features between the groups. Fetal cardiac morphologic parameters were found to be similar between the two groups. When the fetal cardiac functional assessment of the two groups was compared, only mitral E/A ratio results were found to be statistically significantly lower in the CRG than in the control group (p = 0.030).ConclusionThe fetal heart does not seem to be negatively affected by COVID‐19 after recovery from moderate infection. These results about the fetal effect of SARS‐CoV‐2 may improve our limited knowledge of the utility of fetal ECHO in pregnant women who recovered from COVID‐19.

AbstractBackground and AimAnastomotic leakage (AL) in colorectal resection and primary anastomosis is a common and feared complication. Fully covered self‐expandable metal stents (FCSEMSs) have been used for the treatment of AL. It is still unknown whether FCSEMSs affect anastomosis healing negatively by causing ischemia. In an animal study, we investigated the metabolic effects over a FCSEMS covering a stapled colon anastomosis.MethodsSeven pigs were investigated using microdialysis after laparotomy, colon resection, and anastomosis with stent placement. Measurements were done at the proximal and distal ends of the anastomosis and at a reference catheter placed at the small intestine. Measurements of glucose, pyruvate, lactate, glycerol, and the lactate/pyruvate ratio (L/P) were carried out.ResultsLactate and L/P were significantly higher at the oral part of the anastomosis, while glucose showed a small declining tendency. At the distal part of the anastomosis, glucose decreased significantly after the resection but did not reach zero. Lactate increased significantly whereas L/P increased only slightly. Glycerol levels were stable.ConclusionColon resection caused initially hypermetabolism in the intestinal ends next to the resection site. This hypermetabolism neither deteriorated nor turned into ischemia during the initial postoperative course, but the start of hypoxemia could not be excluded during the study and after the placement of an FCSEMS.
Immune checkpoints in T cells during oncogenic γ‐herpesvirus infections
Authors: Münz Christian 
Published: May 2022

AbstractEpstein–Barr virus (EBV) and Kaposi sarcoma‐associated herpesvirus (KSHV) are two persistent oncogenic γ‐herpesviruses with an exclusive tropism for humans. They cause cancers of lymphocyte, epithelial and endothelial cell origin, such as Burkitt's and Hodgkin's lymphoma, primary effusion lymphoma, nasopharyngeal carcinoma, and Kaposi sarcoma. Mutations in immune‐related genes but also adverse events during immune checkpoint inhibition in cancer patients have revealed molecular requirements for immune control of EBV and KSHV. These include costimulatory and coinhibitory receptors on T cells that are currently explored or already therapeutically targeted in tumor patients. This review discusses these co‐receptors and their influence on EBV‐ and KSHV‐associated diseases. The respective studies reveal surprising specificities of some of these receptors for immunity to these tumor viruses, benefits of their blockade for some but not other virus‐associated diseases, and that EBV‐ and KSHV‐specific immune control should be monitored during immune checkpoint inhibition to prevent adverse events that might be associated with their reactivation during treatment.

Published: May 2022

AbstractIn this manuscript, a novel control scheme is proposed to achieve the power quality (PQ) enhancement of renewable energy sources (RES), such as photovoltaic (PV), wind turbine (WT), fuel cell (FC), and battery. The proposed hybrid technique is the consolidation of both the Improved Bat Algorithm (IBat) and Moth Flame Optimization Algorithm (MFOA), therefore it is known as Improved Bat search Algorithm with Moth Flame Optimization Algorithm (IBatMFOA) control strategy. The crossover and mutation function is utilized to modify the bats search behavior function. Here, MFOA is utilized to enhance the searching behavior of IBat technique by reducing the error function. The main goal of proposed IBatMFOA approach is “to enhance the PQ depending on active with reactive power varience.” To attain the target, MFOA is optimized to lessen the power variation. Moreover, the functioning cost of RESs is diminished based on daily with weekly data forecast, like grid electricity price, electrical load, environmental parameters. By using IBatMFOA technique, the entire system efficiency is enhanced. By then, the proposed method is activated in MATLAB site, then the performance is examined with existing methods, like artificial bee colony, Gravitational Search Algorithm, and Firefly algorithm. The active power controller parameters of proposed technique are 8.8554 and 1.8569. The reactive power controller parameters of proposed technique are 8.1657 and 1.5698.
