Huang, Hong published the artcileHydration of ternary cement in the presence of triisopropanolamine, Formula: C9H21NO3, the publication is Construction and Building Materials (2016), 513-521, database is CAplus.

The effects of triisopropanolamine (TIPA) on the strength development and hydration kinetics of a ternary cement containing slag and CaCO₃ were investigated by mixture design. The strength development of the blend was considerably enhanced by the accelerated chem. reactions on each component. A very strong interaction effect of slag and CaCO₃ on the strength enhancement prior to 7 d was observed The addition of TIPA promoted the hydration of laboratory cement by promoting the dissolution of ferrite, which resulted in more CH being released to participate in the reaction with slag. The dissolution of the slag itself was markedly accelerated by TIPA in a simulated highly alk. pore solution The use of TIPA promoted the formation of carboaluminate due to the accelerated C4AF/C3A-CaCO₃ reaction, which stabilized the formation of AFt during hydration. In addition, it confirmed that Fe ions were able to enter the AFt structure during hydration with TIPA.

Xu, Zhiqiang published the artcileHydration of Portland cement with alkanolamines by thermal analysis, Product Details of C9H21NO3, the publication is Journal of Thermal Analysis and Calorimetry (2018), 131(1), 37-47, database is CAplus.

Four types of alkanolamines (i.e., traditional alkanolamines represented by TEA and TIPA and new alkanolamines represented by DEIPA and EDIPA) were added to Portland cement as chem. additives, and their effects on the cement properties and hydration process were investigated. An isothermal calorimeter was used to track the hydration heat flow of the cement pastes with or without alkanolamines. Thermogravimetric analyses were performed to measure the degree of hydration over the course of 28 days. In addition, X-ray diffraction, MIP anal. and SEM were used as auxiliary tests. The results indicated that alkanolamines improved the compressive strength of the cement mortars. It was found that TEA increased the rate of the second hydration of C₃A, and TIPA accelerated the hydration of C₄AF. DEIPA and EDIPA promoted the hydration of both the aluminum and ferrite phases as well as catalyzed the conversion of AFt to the AFm phase. By contrast, the new alkanolamines represented by DEIPA and EDIPA expressed more superior properties.

Xu, Zhiqiang published the artcileResearch on cement hydration and hardening with different alkanolamines, Product Details of C9H21NO3, the publication is Construction and Building Materials (2017), 296-306, database is CAplus.

In this work, six types of alkanolamines (i.e., TEA, TIPA, DEIPA, EDIPA, THEED and THPED) were added into Portland cement as chem. additives, and their effects on phys. properties and hydration of Portland cement as well as mechanism were investigated. The results show that all the alkanolamines expect TEA can effectively improve the degree of cement hydration. TEA delays the hydration of alite because the formation of the TEA-Ca2+ complex inhibits the growth of CH. TIPA accelerates the hydration of C4AF at late stage, but reduce the early strength due to its air-entraining effect. The lower dosages of DEIPA and EDIPA have the advantages of TEA and TIPA, which increase not only the early strength but also the late strength. They promote both the hydration of the aluminum and ferrite phase as well as catalyze the conversion of AFt to AFm, which lead to the optimization of pore size distribution. The effects of THEED and THPED on hydration of Portland cement are similar though their mol. structure are different which improve the late strength and have larger suitable dosage range.

Choi, Younghun published the artcileIdentification, quantification, and prioritization of new emerging pollutants in domestic and industrial effluents, Korea: Application of LC-HRMS based suspect and non-target screening, Application of Triisopropanolamine, the publication is Journal of Hazardous Materials (2021), 123706, database is CAplus and MEDLINE.

The present study was designed to identify recently (or rarely) recognized or unreported substances (RRS or URS) contained in the effluents from water treatment plants in two industrialized urban areas, Gumi and Daegu, in Korea. In addition to 30 initial targets, 72 substances were identified through suspect and non-target screening (SNTS). Among them were 4 RRSs and 22 URSs, resp. The quant. analyses were applied to 35 pharmaceuticals, 15 pesticides, 13 poly-/perfluorinated alkyl substances (PFASs), 2 organophosphate flame retardants (OPFRs), 2 corrosion inhibitors, and 3 metabolites. The highest average concentration was observed for benzotriazole, followed by those for niflumic acid, and metformin. Effluents from Gumi mainly contained benzotriazole and metformin whereas niflumic acid and tramadol were the major components in effluents from Daegu. According to a scoring system based on risk relevant parameters, higher priorities were given to telmisartan, PFOA, and cimetidine. Yet, priorities for some substances were area specific (e.g., benzotriazole from Gumi, PFASs from Daegu), reflecting differences in industry profiles and populations. Many of the RRSs and URSs were recognized as potential hazards. The new identifications and evaluations should be taken into consideration for constant monitoring and management, as do the previously recognized contaminants.

Perina, Dragutin published the artcileCharacterization of Nme5-like gene/protein from the red alga Chondrus crispus, Safety of Triisopropanolamine, the publication is Marine Drugs (2020), 18(1), 13, database is CAplus and MEDLINE.

The Nme gene/protein family of nucleoside diphosphate kinases (NDPK) was originally named after its member Nm23-H1/Nme1, the first identified metastasis suppressor. Human Nme proteins are divided in two groups. They all possess nucleoside diphosphate kinase domain (NDK). Group I (Nme1-Nme4) display a single type NDK domain, whereas Group II (Nme5-Nme9) display a single or several different NDK domains, associated or not associated with extra-domains. Data strongly suggest that, unlike Group I, none of the members of Group II display measurable NDPK activity, although some of them autophosphorylate. The multimeric form is required for the NDPK activity. Group I proteins are known to multimerize, while there are no data on the multimerization of Group II proteins. The Group II ancestral type protein was shown to be conserved in several species from three eukaryotic supergroups. Here, we analyzed the Nme protein from an early branching eukaryotic lineage, the red alga Chondrus crispus. We show that the ancestral type protein, unlike its human homolog, was fully functional multimeric NDPK with high affinity to various types of DNA and dispersed localization throughout the eukaryotic cell. Its overexpression inhibits both cell proliferation and the anchorage-independent growth of cells in soft agar but fails to deregulate cell apoptosis. We conclude that the ancestral gene has changed during eukaryotic evolution, possibly in correlation with the protein function.

Gago-Ferrero, Pablo published the artcileSuspect Screening and Regulatory Databases: A Powerful Combination To Identify Emerging Micropollutants, Product Details of C9H21NO3, the publication is Environmental Science & Technology (2018), 52(12), 6881-6894, database is CAplus and MEDLINE.

This study demonstrates that regulatory databases combined with the latest advances in high resolution mass spectrometry (HRMS) can be efficiently used to prioritize and identify new, potentially hazardous pollutants being discharged into the aquatic environment. Of the approx. 23000 chems. registered in the database of the National Swedish Product Register, 160 potential organic micropollutants were prioritized through quant. knowledge of market availability, quantity used, extent of use on the market, and predicted compartment-specific environmental exposure during usage. Advanced liquid chromatog. (LC)-HRMS-based suspect screening strategies were used to search for the selected compounds in 24 h composite samples collected from the effluent of three major wastewater treatment plants (WWTPs) in Sweden. In total, 36 tentative identifications were successfully achieved, mostly for substances not previously considered by environmental scientists. Of these substances, 23 were further confirmed with reference standards, showing the efficiency of combining a systematic prioritization strategy based on a regulatory database and a suspect-screening approach. These findings show that close collaboration between scientists and regulatory authorities is a promising way forward for enhancing identification rates of emerging pollutants and expanding knowledge on the occurrence of potentially hazardous substances in the environment.

Borkowski, Olivier published the artcileLarge scale active-learning-guided exploration for in vitro protein production optimization, Computed Properties of 122-20-3, the publication is Nature Communications (2020), 11(1), 1872, database is CAplus and MEDLINE.

Abstract: Lysate-based cell-free systems have become a major platform to study gene expression but batch-to-batch variation makes protein production difficult to predict. Here we describe an active learning approach to explore a combinatorial space of ~4,000,000 cell-free buffer compositions, maximizing protein production and identifying critical parameters involved in cell-free productivity. We also provide a one-step-method to achieve high quality predictions for protein production using minimal exptl. effort regardless of the lysate quality.

Moubri, K. published the artcileDiscovery of a recombinant Babesia canis supernatant antigen that protects dogs against virulent challenge infection, Category: alcohols-buliding-blocks, the publication is Veterinary Parasitology (2018), 21-29, database is CAplus and MEDLINE.

Soluble parasite antigens (SPA) in supernatants of in vitro cultures of Babesia canis can be used to vaccinate dogs against virulent B. canis infection. The moment that immunity becomes apparent coincides with the appearance of antibodies against SPA in the serum of the vaccinated animals. This so-called vaccination-challenge serum (VC-serum) was used to precipitate antigens from B. canis culture supernatants in agarose gels. This antigen preparation was then used to analyze the reactivity of sera from vaccinated dogs on western blots showed that the first appearance of antibody reactivity against a protein that migrated at the 39 kDa position in SDS-PAGE gels was associated with the moment vaccinated dogs started to recover from a virulent challenge infection. In addition, pulse-chase experiments revealed that a 39-40 kDa doublet was released into the supernatant of B. canis cultures starting 15 min after the chase. This doublet was specifically precipitated by VC-serum, thus corroborating that the 39-40 kDa doublet in SPA preparations was of parasite origin. Partial amino acid sequencing allowed the discovery of the gene that encoded the 39-40 kDa doublet (canine Babesia antigen; CBA). The full-length gene was cloned and expressed in E. coli. The recombinant CBA protein (rCBA) was recognized by VC-serum, and antibodies against rCBA precipitated the 39 kDa antigen of SPA preparations and of merozoites of B. canis. In addition, anti-rCBA serum reacted with the surface of B. canis merozoites (but not with B. rossi merozoites) in immunofluorescence. Vaccination of dogs with rCBA induced antibodies against rCBA, which recognized B. canis merozoites. Vaccinated dogs were protected against virulent challenge infection by limiting parasite proliferation. As a result, the development of clin. signs was prevented and the animals self-cured. In contrast, six out of seven non-vaccinated control dogs developed relatively high parasitemia and serious clin. signs associated with poor tissue perfusion. This antigen can be used to replace the SPA antigen in the conventional B. canis vaccines, which eliminates the need for dog blood and serum for vaccine production
