Wang, Shiru published the artcileCoupling Suspect and Nontarget Screening with Mass Balance Modeling to Characterize Organic Micropollutants in the Onondaga Lake-Three Rivers System, COA of Formula: C9H21NO3, the publication is Environmental Science & Technology (2021), 55(22), 15215-15226, database is CAplus and MEDLINE.

Characterizing the occurrence, sources, and fate of organic micropollutants (OMPs) in lake-river systems serves as an important foundation for constraining the potential impacts of OMPs on the ecosystem functions of these critical landscape features. In this work, we combined suspect and nontarget screening with mass balance modeling to investigate OMP contamination in the Onondaga Lake-Three Rivers system of New York. Suspect and nontarget screening enabled by liquid chromatog.-high-resolution mass spectrometry led to the confirmation and quantification of 105 OMPs in water samples collected throughout the lake-river system, which were grouped by their concentration patterns into wastewater-derived and mixed-source clusters via hierarchical cluster anal. Out of these 105 OMPs, four OMPs (i.e., galaxolidone, diphenylphosphinic acid, N-butylbenzenesulfonamide, and triisopropanolamine) were prioritized and identified by nontarget screening based on their characteristic vertical distribution patterns during thermal stratification in Onondaga Lake. Mass balance modeling performed using the concentration and discharge data highlighted the export of OMPs from Onondaga Lake to the Three Rivers as a major contributor to the OMP budget in this lake-river system. Overall, this work demonstrated the utility of an integrated screening and modeling framework that can be adapted for OMP characterization, fate assessment, and load apportionment in similar surface water systems.

Roy, Ekta published the artcileCarbon dot/TAT peptide co-conjugated bubble nanoliposome for multicolor cell imaging, nuclear-targeted delivery, and chemo/photothermal synergistic therapy, Product Details of C9H21NO3, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2017), 144-157, database is CAplus.

A pioneering nucleus-targeting dual-functional thermosensitive bubble-generating liposome as drug carrier has been developed with conjugated cell penetrating peptide and photothermal agent (CDs) for multi-color cell imaging and combination (chemo- and photothermal) therapy of cancer, using doxorubicin as drug mol. The liposome was prepared by ‘inhouse’ synthesized precursors mols., to reduce the cost of production in comparison to the earlier reported liposomes. This drug carrier was proposed to target nucleus of the cancer cells, owing to specific and selective cell-penetrating property of TAT, followed by burst but stable drug release due to decomposition of bubble forming agent present inside the liposome core, by being subjected to near-IR (NIR) irradiation (i.e. photothermal conversion of radiation to heat). The in-vitro temperature and/or NIR-triggered release study indicated that liposome was sensitive towards heat and able to generate the sufficient temperature of 68 °C in the presence of NIR-laser source. The in vivo experiment was also performed to explore the NIR-responsive hyperthermia in the mice body. The as prepared bubble containing liposome-based drug delivery system exhibits superior stability, no drug leakage and enhanced in vitro and in vivo drug delivery with efficient cancer cell killing via combination therapy. The multicolor fluorescence obtained via CDs improves the accuracy of the cell imaging study as well as works as a key component for photothermal treatment of cancer. The results obtained in the study demonstrated that the designed smart drug carrier have great potential in the field of cancer theragnosis i.e. imaging, targeted drug delivery, and treatment.

Ri, Jin Hyok published the artcilePreparation of cement grinding aids based on alumina compounds, Formula: C9H21NO3, the publication is Madencilik (2020), 59(2), 123-129, database is CAplus.

When the cement grinding is performed in the ball mill, the grinding efficiency decreases due to the aggregation of the particles by the electrostatic phenomenon. Therefore, a lot of techniques for preventing agglomeration using various grinding aids have been introduced. In this study, for mineral grinding, the grinding aid composition including a water-soluble aluminate compound and the grinding method in which this grinding aid is used were described. Grinding aids based on aluminate-based compounds not only have high grinding efficiency but are also thermally stable as they are inorganic materials. Compared with the conventional grinding aids based on organic materials such as DEG and TIPA, even if the solid content is half contained, the grinding efficiency is similar and thus the cost can be reduced to half.

Penders-van Elk, Nathalie J. M. C. published the artcileCombined Effect of Temperature and pK_a on the Kinetics of Absorption of Carbon Dioxide in Aqueous Alkanolamine and Carbonate Solutions with Carbonic Anhydrase, Related Products of alcohols-buliding-blocks, the publication is Industrial & Engineering Chemistry Research (2016), 55(38), 10044-10054, database is CAplus.

In present work the absorption of carbon dioxide in aqueous N-methyldiethanolamine, N,N-dimethylethanolamine, and triisopropanolamine solutions with and without the enzyme carbonic anhydrase has been studied in a stirred cell reactor at temperatures varying between 278 and 313 K, at an alkanolamine concentration of 1 kmol m^-3 and carbonic anhydrase concentrations ranging from 0 to 2.4 kg m^-3, resp. The exptl. data from these experiments have been used to fit the obtained rate constant for the enzymic CO₂ hydration to the Bronsted relation: ln(k) = A(pK_a) + B + C/T. In addition to the carbon dioxide absorption in the three tertiary alkanolamines, the absorption of carbon dioxide in next three solvents had been studied: 0.3 kmol m^-3 potassium carbonate, 0.3 kmol m^-3 sodium carbonate, and 0.2 kmol m^-3 2-amino-2-methyl-1-propanol. The kinetics from these solvents are well predicted by the relation fitted to the data of the tertiary amines only.

Tan, Hongbo published the artcileEffect of organic alkali on compressive strength and hydration of wet-grinded granulated blast-furnace slag containing Portland cement, HPLC of Formula: 122-20-3, the publication is Construction and Building Materials (2019), 10-18, database is CAplus.

In this study, a com. available ground granulated blast-furnace slag (GGBS) was further processed by wet grinding, and WGGBS (wet-grinded GGBS) slurry with superfine particles was obtained. To avoid self-hydration of slag and augment the grinding efficiency, one com. available polycarboxylate superplasticizer was added. The binder, composed of 10.0% cement and 90.0% WGGBS with the addition of 0.05% triethanolamine (TEA) and 0.05% triisopropanolamine (TIPA), was designed; the cement was added to provide alkali environment and calcium ions, and organic alkali was used to promote the dissolution of GGBS. The compressive strength of mortar and hydration mechanism was investigated. The results showed that wet grinding exhibited high grinding efficiency; D(50) value of particle size distribution of WGGBS was reduced from 18μm to 2.10μm by wet grinding for one hour. Compressive strength of hardened WGGBS mortar was 20 MPa and 28 MPa at 7 d and 28 d, and 10% cement replacement ratio of the WGGBS increased the strength to 24.6 MP at 7 d and 32.2 MPa at 28 d. Furthermore, in C-WGGBS, 0.05% TEA increased the 7 d strength by 23%, with the value of 30.27 MPa, but 0.05%TIPA slightly reduced it to 23.5 MPa, with a decrease by 5%. Mechanism behind the increase was due to the accelerated formation of hydrotalcite-like phase, despite the retarding effect on formation of C-(A)S-H gel; the slight decline by TIPA was mainly because of the retarding effect of formation of C-(A)S-H gel as well as its air-entraining effect. Moreover, both TEA and TIPA increased the 28 d strength of cement-WGGBS system, because TEA and TIPA were able to facilitate ferric and aluminum dissolution and expedite the formation of C-(A)S-H gel as well as hydrotalcite-like phase. Addnl., it was worth noting that 0.05% TEA could make 28 d strength of the binder, composed of only 10% cement, reach 43.7 MPa, in accordance with the requirement of 42.5 grade cement.

Cationic surfactants containing different head-groups have been synthesized by interaction of tetradecyl bromide and amines having hydroxyalkyl group (monoethanolamine, diethanolamine, triethanolamine, methylethanolamine, methyldiethanolamine, diethanolisopropanolamine, ethanoldiisopropanolamine, triisopropanolamine). Surfactivity parameters of the synthesized cationic surfactants have been determined by measurements of surface tension and electroconductance. The character of change of the colloidal-chem. parameters with an increase of the number of hydroxyethyl and hydroxyisopropyl groups in the head-group of the cationic surfactants has been established. The synthesized cationic surfactants possess effective antibacterial and antifungal properties.

Archaea swim using the archaellum (archaeal flagellum), a reversible rotary motor consisting of a torque-generating motor and a helical filament, which acts as a propeller. Unlike the bacterial flagellar motor (BFM), ATP (adenosine-5a²-triphosphate) hydrolysis probably drives both motor rotation and filamentous assembly in the archaellum. However, direct evidence is still lacking due to the lack of a versatile model system. Here, we present a membrane-permeabilized ghost system that enables the manipulation of intracellular contents, analogous to the triton model in eukaryotic flagella and gliding Mycoplasma. We observed high nucleotide selectivity for ATP driving motor rotation, neg. cooperativity in ATP hydrolysis, and the energetic requirement for at least 12 ATP mols. to be hydrolyzed per revolution of the motor. The response regulator CheY increased motor switching from counterclockwise (CCW) to clockwise (CW) rotation. Finally, we constructed the torque-speed curve at various [ATP]s and discuss rotary models in which the archaellum has characteristics of both the BFM and F1-ATPase. Because archaea share similar cell division and chemotaxis machinery with other domains of life, our ghost model will be an important tool for the exploration of the universality, diversity, and evolution of biomol. machinery.

Nakanishi, Masako published the artcileDietary walnut supplementation alters mucosal metabolite profiles during DSS-induced colonic ulceration, Application of Triisopropanolamine, the publication is Nutrients (2019), 11(5), 1118, database is CAplus and MEDLINE.

Walnuts contain a complex array of natural compounds and phytochems. that exhibit a wide range of health benefits, including protection against inflammation and colon cancer. In this study, we assess effect of dietary supplementation with walnuts on colonic mucosal injury induced in mice by ulcerogenic agent, dextran sodium sulfate (DSS). C57Bl/6J mice were started on the Total Western Diet supplemented with freshly-ground whole walnuts (0, 3.5, 7 and 14% g/kg) 2 wk prior to a 5-day DSS treatment and walnut diets were continued throughout the entire exptl. period. In a sep. study, a discovery-based metabolite profiling anal. using liquid chromatog. tandem mass spectrometry was performed on fecal samples and colonic mucosa following two weeks of walnut supplementation. Dietary walnut supplementation showed significant effects in the 10-day post-DSS recovery-phase study, in which the extent of ulceration was significantly reduced (7.5% vs. 0.3%, p < 0.05) with 14% walnuts. In the metabolite-profiling anal., walnuts caused a significant increase in several polyunsaturated fatty acids, including docosahexaenoic acid and 9-oxo-10(E),12(E)-octadecadienoic acid (9-oxoODA), as well as kynurenic acid. In colon tissue samples, walnuts caused a significant increase in the levels of S-adenosylhomocysteine and betaine, important components of fatty acid β-oxidation These metabolite changes may contribute in part to the observed protection against DSS-induced inflammatory tissue injury.

Schaffert, Lena published the artcileEvaluation of vector systems and promoters for overexpression of the acarbose biosynthesis gene acbC in Actinoplanes sp. SE50/110, Name: Triisopropanolamine, the publication is Microbial Cell Factories (2019), 18(1), 1-16, database is CAplus and MEDLINE.

Background: Actinoplanes sp. SE50/110 is a natural producer of acarbose. It has been extensively studied in the last decades, which has led to the comprehensive anal. of the whole genome, transcriptome and proteome. First genetic and microbial techniques have been successfully established allowing targeted genome editing by CRISPR/Cas9 and conjugal transfer. Still, a suitable system for the overexpression of singular genes does not exist for Actinoplanes sp. SE50/110. Here, we discuss, test and analyze different strategies by the example of the acarbose biosynthesis gene acbC. Results: The integrative φC31-based vector pSET152 was chosen for the development of an expression system, as for the replicative pSG5-based vector pKC1139 unwanted vector integration by homologous recombination was observed Since simple gene duplication by pSET152 integration under control of native promoters appeared to be insufficient for overexpression, a promoter screening experiment was carried out. We analyzed promoter strengths of five native and seven heterologous promoters using transcriptional fusion with the gusA gene and glucuronidase assays as well as reverse transcription quant. This system will help altering transcript amounts of singular genes, that can be used to unclench metabolic bottlenecks and to redirect metabolic resources. Furthermore, an essential tool is provided, that can be transferred to other subspecies of Actinoplanes and industrially relevant derivatives
