Fang, Jun published the artcileSooting tendency analysis of oxygenate-diesel blended fuels by the affecting indicators of carbon number, oxygen content and H/C ratio, Product Details of C11H22O2, the main research area is oxygenate diesel blended fuel sooting tendency analysis.

This study exptl. assessed the sooting tendencies of the diesel fuel blended with typical oxygenated additives. Based on the known influential factors of oxygenated functional group, oxygen content, carbon number, and saturation degree, the functional numbers of carbon and oxygen atoms of the mols. were determined by considering the actual bonding ratio of carbon and oxygen producing CO and CO2 during the combustion of blends. The affecting indicators along with a calculation algorithm were proposed, taking into account the actual effect of each factor on sooting tendency. So-called indicators were termed the affecting oxygen content, carbon number and H/C ratio. Normalized Oxygen Extended Sooting Index (OESI) values incorporating the smoke point values were established to decrease with increasing blending percentage of the oxygenated additives in blends, following an exponential fitting relationship. The resulting exponents quantified the soot inhibition ability of the oxygenated additives, which decreased in the order: ethanol (EA) > n-butanol (NBA) > Me tertiary-Bu ether (MTBE) > dimethoxy methane (DMM) > Me decanoate (MD) > Me butanoate (MB) > di-Bu maleate (DBM) > di-Me carbonate (DMC). A combination of the absolute affecting indicator values generated by the suggested algorithm and their relative weights obtained by Relative Weight Anal. (RWA) could interpret the sooting tendency of most of the blended fuels very well. It was found that the sooting tendency was mainly determined by the absolute values of the affecting indicators, and the priority should follow the results by RWA, that decreased in the order of affecting carbon number > affecting oxygen content > affecting H/C ratio. This study could benefit the evaluation of the sooting tendency of the oxygenate-diesel blended fuels.

Matrisciano, Andrea published the artcileAn a priori thermodynamic data analysis based chemical lumping method for the reduction of large and multi-component chemical kinetic mechanisms, Category: esters-buliding-blocks, the main research area is decane methylnaphthalene combustion mechanism kinetics.

A chem. species lumping approach for reduction of large hydrocarbons and oxygenated fuels is presented. The methodol. is based on an a priori anal. of the Gibbs free energy of the isomer species which is then used as main criteria for the evaluation of lumped group. Isomers with similar Gibbs free energy are lumped assuming they present equal concentrations when applied to standard reactor conditions. Unlike several lumping approaches found in literature, no calculation results from the primary mechanism have been employed prior to the application of our chem. lumping strategy. An 807 species and 7807 individual reactions detailed mechanism comprising n-decane, α-methylnaphthalene and Me decanoate has been used. The thermodn. data have been analyzed and 74 isomer groups have been identified within the oxidation of n-decane and Me decanoate. The mechanism reduction has led to a mechanism size of 463 species and 7600 reactions. Thereafter the lumped mechanism has been checked under several reactor conditions and over a broad range of temperature, pressure, and equivalence ratio in order to quantify the accuracy of the proposed approach. In all cases, very good agreement between the predictions obtained using the lumped and the detailed mechanism has been observed with an overall absolute error below 12%. Effects of the lumping procedure on sensitivities and on isomer concentrations were considered to further demonstrate the validity of the proposed approach.

Roberts, Rebecca E. published the artcileOdorant receptor orthologues in conifer-feeding beetles display conserved responses to ecologically relevant odors, Application In Synthesis of 140-11-4, the main research area is conifer feeding beetle odor odorant receptor response; Coleoptera; Curculionidae; HEK293 cells; de-orphanization; evolutionary conservation; functional characterization.

Insects are able to detect a plethora of olfactory cues using a divergent family of odorant receptors (ORs). Despite the divergent nature of this family, related species frequently express several evolutionarily conserved OR orthologues. In the largest order of insects, Coleoptera, it remains unknown whether OR orthologues have conserved or divergent functions in different species. Using HEK293 cells, we addressed this question through functional characterization of two groups of OR orthologues in three species of the Curculionidae (weevil) family, the conifer-feeding bark beetles Ips typographus L. (“”Ityp””) and Dendroctonus ponderosae Hopkins (“”Dpon””) (Scolytinae), and the pine weevil Hylobius abietis L. (“”Habi””; Molytinae). The ORs of H. abietis were annotated from antennal transcriptomes. The results show highly conserved response specificities, with one group of orthologues (HabiOR3/DponOR8/ItypOR6) responding exclusively to 2-phenylethanol (2-PE), and the other group (HabiOR4/DponOR9/ItypOR5) responding to angiosperm green leaf volatiles (GLVs). Both groups of orthologues belong to the coleopteran OR subfamily 2B, and share a common ancestor with OR5 in the cerambycid Megacyllene caryae, also tuned to 2-PE, suggesting a shared evolutionary history of 2-PE receptors across two beetle superfamilies. The detected compounds are ecol. relevant for conifer-feeding curculionids, and are probably linked to fitness, with GLVs being used to avoid angiosperm nonhost plants, and 2-PE being important for intraspecific communication and/or playing a putative role in beetle-microbe symbioses. To our knowledge, this study is the first to reveal evolutionary conservation of OR functions across several beetle species and hence sheds new light on the functional evolution of insect ORs.

Lin, Yi-Sian published the artcileGWAS Meta-Analysis Reveals Shared Genes and Biological Pathways between Major Depressive Disorder and Insomnia, Product Details of C12H9N3O5S, the main research area is major depressive disorder insomnia gene biol pathway metaanalysis; GWAS; MDD; STRING; comorbidity; eQTL; gene network; insomnia; meta-analysis.

Major depressive disorder (MDD) is one of the most prevalent and disabling mental disorders worldwide. Among the symptoms of MDD, sleep disturbance such as insomnia is prominent, and the first reason patients may seek professional help. However, the underlying pathophysiol. of this comorbidity is still elusive. Recently, genome-wide association studies (GWAS) have begun to unveil the genetic background of several psychiatric disorders, including MDD and insomnia. Identifying the shared genomic risk loci between comorbid psychiatric disorders could be a valuable strategy to understanding their comorbidity. This study seeks to identify the shared genes and biol. pathways between MDD and insomnia based on their shared genetic variants. First, we performed a meta-anal. based on the GWAS summary statistics of MDD and insomnia obtained from Psychiatric Genomics Consortium and UK Biobank, resp. Next, we associated shared genetic variants to genes using two gene mapping strategies: (a) positional mapping based on genomic proximity and (b) expression quant. trait loci (eQTL) mapping based on gene expression linkage across multiple tissues. As a result, a total of 719 shared genes were identified. Over half (51%) of them are protein-coding genes. Functional enrichment anal. shows that the most enriched biol. pathways are related to epigenetic modification, sensory perception, and immunol. signatures. We also identified druggable targets using a network approach. Together, these results may provide insights into understanding the genetic predisposition and underlying biol. pathways of comorbid MDD and insomnia symptoms.

Hyun, Soo-Wang published the artcileToxicological effects of urban particulate matter on corneal and conjunctival epithelial cells, Recommanded Product: 2′,7′-Dichloro-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-diyl diacetate, the main research area is toxicol effect corneal conjunctival epithelial cell; Cell cycle; Cell death; Corneal/conjunctival epithelial cells; Mucin; Urban particulate mater.

Abstract: Exposure to urban particulate matter (UPM) is a high-risk factor for various ocular surface diseases, including dry eye syndrome. However, the effects of UPM on corneal and conjunctival epithelium damage have not been fully elucidated. In this study, we investigated the toxicol. effects of UPM exposure at high concentrations by using in vitro cultures. The cell viability, mucin expression, and the secreted inflammatory mediators of corneal and conjunctival epithelial cells was observed at 24 h after exposure to UPM. The progression of cell cycle was also examined by flow cytometry at 24 h after exposure to UPM. UPM reduced cell viability in a dose-dependent manner and increased cell population in S and G2 phase. The expression of mucin-1 was attenuated by UPM exposure, but that of mucin-4 was not. UPM increased interleukin (IL)-6 release and decreased IL-8 release. The intensity of 2′ ,7′-dichlorofluorescein diacetate (DCF-DA) was highest at 4 h of UPM exposure. In conclusion, these results suggest that UPM causes the disruption of corneal and conjunctival epithelium by decreasing cell viability, altering cell cycle, disrupting mucin, and regulating inflammatory mediators.

Moghadam, S. Arbabi published the artcileCell death and survival due to cytotoxic exposure modelled as a two-state Ising system, Quality Control of 55981-09-4, the main research area is Ising system cell death survival cytotoxic exposure; Ising model; bystander effect; cancer cell response; cytotoxicity; phase transition.

Cancer chemotherapy agents are assessed for their therapeutic utility primarily by their ability to cause apoptosis of cancer cells and their potency is given by an IC50 value. Chemotherapy uses both target-specific and systemic-action drugs and drug combinations to treat cancer. It is important to judiciously choose a drug type, its dosage and schedule for optimized drug selection and administration. Consequently, the precise math. formulation of cancer cells’ response to chemotherapy may assist in the selection process. In this paper, we propose a math. description of the cancer cell response to chemotherapeutic agent exposure based on a time-tested phys. model of two-state multiple-component systems near criticality. We describe the Ising model methodol. and apply it to a diverse panel of cytotoxic drugs administered against numerous cancer cell lines in a dose- response manner. The analyzed dataset was generated by the Netherlands Translational Research Center B.V. (Oncolines). This approach allows for an accurate and consistent anal. of cytotoxic agents’ effects on cancer cell lines and reveals the presence or absence of the bystander effect through the interaction constant By calculating the susceptibility function, we see the value of IC50 coinciding with the peak of this measure of the system’s sensitivity to external perturbations.

Xu, Siyu published the artcileAnti-infective nitazoxanide disrupts transcription of ribosome biogenesis-related genes in yeast, Related Products of esters-buliding-blocks, the main research area is Saccharomyces nitazoxanide transcriptome ribosome; Gene ontology; Over-representation analysis; RNA-seq; Ribosome; SSU processome; Thiazolides.

Abstract: Background: Nitazoxanide is a broad-spectrum, anti-parasitic, anti-protozoal, anti-viral drug, whose mechanisms of action have remained elusive. Objective: In this study, we aimed to provide insight into the mechanisms of action of nitazoxanide and the related eukaryotic host responses by characterizing transcriptome profiles of Saccharomyces cerevisiae exposed to nitazoxanide. Methods: RNA-Seq was used to investigate the transcriptome profiles of three strains of S. cerevisiae with dsRNA virus-like elements, including a strain that hosts M28 encoding the toxic protein K28. From the strain with M28, an addnl. sub-strain was prepared by excluding M28 using a nitazoxanide treatment. Results: Our transcriptome anal. revealed the effects of nitazoxanide on ribosome biogenesis. Many genes related to the UTP A, UTP B, Mpp10-Imp3-Imp4, and Box C/D snoRNP complexes were differentially regulated by nitazoxanide exposure in all of the four tested strains/sub-strains. Examples of the differentially regulated genes included UTP14, UTP4, NOP4, UTP21, UTP6, and IMP3. The comparison between the M28-laden and non-M28-laden sub-strains showed that the mitotic cell cycle was more significantly affected by nitazoxanide exposure in the non-M28-laden sub-strain. Conclusions: Overall, our study reveals that nitazoxanide disrupts regulation of ribosome biogenesis-related genes in yeast.

Magnotti, Gina M. published the artcileAssessing fuel property effects on cavitation and erosion propensity using a computational fuel screening tool, Name: Methyl decanoate, the main research area is computational fuel screening tool erosion propensity.

To advance compression ignition combustion strategies, researchers have evaluated fuel property effects and their impact on achieving higher efficiencies and lower emissions levels relative to current capabilities. Within the Department of Energy′s Co-Optima initiative, there has been a recent focus on understanding the influence of fuel properties on fuel injection performance. To help identify candidate fuels that can meet desired injector performance metrics, a computational fuel screening tool is under development that can link fuel properties with the tendency of a given fuel to cavitate and lead to cavitationinduced erosion. In the initial development of this tool, five liquid fuel properties were selected to represent candidate fuels, namely, d., viscosity, vapor pressure, surface tension, and heat of vaporization. A design of experiments methodol. was used to generate a set of pseudofuel cases, which can represent the main effects and interactions among the fuel properties and be related to cavitation erosion predictions. Large eddy simulations were performed using a mixture modeling approach to predict the cavitation and erosion propensity of these pseudofuels in terms of the mean fuel vapor mole fraction and stored impact energy from repeated cloud collapse events. The low-order regression models generated from this study revealed the importance of liquid fuel d. on cavitation formation, whereas liquid viscosity was found to have a strong neg. correlation with erosion severity. The surrogate models were then used in the fuel screening tool to rank the cavitation and erosion tendency of four candidate single-component fuels: Me decanoate, iso-octane, ethanol, and n-dodecane. While the fuel screening tool was not able to quant. predict the cavitation and erosion response metrics, the tool was able to accurately rank the relative cavitation and erosion propensity of the four fuels. Overall, ethanol and iso-octane were observed to produce the highest levels of cavitation and erosion, resp.

Lima, Nayana F. published the artcileIn Vivo Treatment with the Combination of Nitazoxanide and Flubendazole Induces Gluconeogenesis and Protein Catabolism in Taenia crassiceps cysticerci, Recommanded Product: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is Taenia gluconeogenesis nitazoxanide flubendazole; Drugs combination; Experimental cysticercosis; Flubendazole; Metabolism; Nitazoxanide.

Abstract: Purpose: Cysticercosis is the presence of Taenia solium larva in humans or swines tissues. It is a public health problem related to bad hygienic habits and consumption of infected pork. T. crassiceps is a widely used cysticercosis exptl. model. The combination of two effective drugs such as nitazoxanide (NTZ) and flubendazole (FBZ) may potentialize their effect. The aim of this study was to use biochem. anal. to determine the metabolic impact of the combination of NTZ and FBZ on cysticerci inoculated i.p. in mice. Methods: Balb/c mice i.p. infected with T. crassiceps cysticerci received a single oral dose NTZ/FBZ (50 mg/kg). 24 h after the treatment the cysticerci were removed, frozen and analyzed by high performance liquid chromatog. regarding the detection of the following metabolic pathways: glycolysis, gluconeogenesis, homolactic fermentation, tricarboxylic acid cycle, proteins catabolism and fatty acids oxidation Results: The treatment with the drugs combination induced a statistically significant increase in gluconeogenesis and in protein catabolism when compared to the control groups. Conclusion: The drugs combination is potentialized and capable of causing greater metabolic stress than the sep. treatment with NTZ or FBZ, showing its potential for an alternative cysticercosis treatment.

Dias, L. G. published the artcileAroma profile of rice varieties by a novel SPME method able to maximize 2-acetyl-1-pyrroline and minimize hexanal extraction, Synthetic Route of 140-11-4, the main research area is acetyl pyrroline hexanal rice aroma extraction SPME method; 2-acetyl-1-pyrroline; Aromatic rice; Experimental design; PCA; SPME; Volatile compound.

The solid phase microextraction (SPME) has been the most used technique for the extraction of volatile compounds from rice because of its easy operation and solvent-free. The extraction parameters, sample mass and incubation temperature, were optimized through a central composite rotational design (CCRD), aiming at maximizing the extraction of 2-acetyl-1-pyrroline (2AP), the main compound responsible for the aroma in aromatic rice, and minimizing the generation of hexanal, a marker of lipid oxidation Besides, the time of sample incubation and fiber exposure for the extraction of the volatile compounds from rice were determined The optimized conditions for SPME were: 2.5 g of ground rice in a 20 mL vial, sample incubation at 80°C for 60 min and exposure of the divinylbenzene/carboxene/polydimethylsiloxane (DVB/CAR/PDMS) fiber in the headspace for 10 min. The optimized method was successfully applied to 12 varieties of rice and principal component anal. (PCA) was performed to observe similarities in their volatile profile. A total of 152 volatile compounds were identified among the different rice varieties. From these, 42 were identified in arborio rice, 47 in basmati brand A, 43 in basmati brand B, 55 in black rice, 63 in brown rice, 39 in jamine rice, 50 in parboiled brown rice, 43 in parboiled rice, 54 in red rice, 63 in sasanishiki rice, 46 in white rice and 70 in wild rice.
