Hu, Ping; Zhao, Fangzhou; Wang, Jing; Zhu, Weiyun published an article in 2021, the title of the article was Metabolomic profiling reveals the effects of early-life lactoferrin intervention on protein synthesis, energy production and antioxidative capacity in the liver of suckling piglets.Synthetic Route of 32462-30-9 And the article contains the following content:

This study aimed to determine the effects of an early-life lactoferrin (LF) intervention on liver metabolism in suckling piglets. Sixty newborn piglets with an average initial body weight (BW) of 1.51 ± 0.05 kg were assigned to a control (CON) group and an LF group. At age 1 to 7 days, the piglets in the LF group were orally administered LF solution (0.5 g per kg BW daily), whereas the piglets in the CON group were orally administered the same dose of physiol. saline. Plasma, jejunum and liver samples were collected on days 8 and 21. The LF piglets showed a decreased plasma urea nitrogen level on day 8 and an increased plasma albumin level on day 21. Pathway anal. of the metabolomic profiles showed that the LF treatment affected amino acid metabolism in the liver. In addition, the LF treatment upregulated the gene expression levels of proteolytic enzymes and amino acid transporters (APA, APN, EAAC1, Pept1, CAT1, B0AT1 and ASCT2) in the jejunum, and it enhanced the phosphorylation levels of mTOR and p70S6K in the liver. The LF treatment also upregulated the expression of a β-oxidation-related gene (CPT1) and affected the tricarboxylic acid cycle in the liver on day 21. Furthermore, the LF piglets showed a decreased level of malondialdehyde and increased levels of GSH, GSH-Px and GCLC in the liver mitochondria. Overall, the early-life LF intervention affected the protein synthesis, energy production and antioxidative capacity in the liver of the neonatal piglets. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).Synthetic Route of 32462-30-9

Deidda, Martino; Noto, Antonio; Cadeddu Dessalvi, Christian; Andreini, Daniele; Andreotti, Felicita; Ferrannini, Eleuterio; Latini, Roberto; Maggioni, Aldo P.; Magnoni, Marco; Mercuro, Giuseppe; on behalf of the CAPIRE Investigators published an article in 2022, the title of the article was Why Do High-Risk Patients Develop or Not Develop Coronary Artery Disease? Metabolic Insights from the CAPIRE Study.Computed Properties of 473-81-4 And the article contains the following content:

Traditional cardiovascular (CV) risk factors (RFs) and coronary artery disease (CAD) do not always show a direct correlation. We investigated the metabolic differences in a cohort of patients with a high CV risk profile who developed, or did not develop, among those enrolled in the Coronary Atherosclerosis in Outlier Subjects: Protective and Novel Individual Risk Factors Evaluation (CAPIRE) study. We studied 112 subjects with a high CV risk profile, subdividing them according to the presence (CAD/High-RFs) or absence of CAD (No-CAD/High-RFs), assessed by computed tomog. angiog. The metabolic differences between the two groups were identified by gas chromatog.-mass spectrometry. Characteristic patterns and specific metabolites emerged for each of the two phenotypic groups: high concentrations of pyruvic acid, pipecolic acid, p-cresol, 3-aminoisobutyric acid, isoleucine, glyceric acid, lactic acid, sucrose, phosphoric acid, trimethylamine-N-oxide, 3-hydroxy-3-methylglutaric acid, erythritol, 3-hydroxybutyric acid, glucose, leucine, and glutamic acid; and low concentrations of cholesterol, hypoxanthine, glycerol-3-P, and cysteine in the CAD/High-RFs group vs the No-CAD/High-RFs group. Our results show the existence of different metabolic profiles between patients who develop CAD and those who do not, despite comparable high CV risk profiles. A specific cluster of metabolites, rather than a single marker, appears to be able to identify novel predisposing or protective mechanisms towards CAD beyond classic CVRFs. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Computed Properties of 473-81-4

Chen, Jiying; Zhou, Qinger; Zhang, Yonggang; Tan, Wenqing; Gao, Hanchao; Zhou, Liying; Xiao, Shuixiu; Gao, Jinhua; Li, Jing; Zhu, Zhiying published an article in 2021, the title of the article was Discovery of novel serum metabolic biomarkers in patients with polycystic ovarian syndrome and premature ovarian failure.Recommanded Product: H-Phg(4-OH)-OH And the article contains the following content:

Several widely recognized metabolites play a role in regulating the pathophysiol. processes of various disorders. Nonetheless, the lack of effective biomarkers for the early diagnosis of polycystic ovarian syndrome (PCOS) and premature ovarian failure (POF) has led to the discovery of serum-based metabolic biomarkers for these disorders. We aimed to identify various differentially expressed metabolites (DEMs) through serum-based metabolic profiling in patients with PCOS and POF and in healthy individuals by using liquid chromatog.-mass spectrometry anal. Furthermore, heatmap clustering, correlation, and Z-score analyses were performed to identify the top DEMs. Kyoto Encyclopedia of Genes and Genomes enriched pathways of DEMs were determined using metabolite-based databases. Moreover, the clin. significance of these DEMs was evaluated on the basis of area under the receiver operating characteristic curve. Significantly dysregulated expressions of several metabolites were observed in the intergroup comparisons of the PCOS, POF, and healthy control groups. Furthermore, 6 DEMs were most frequently observed among the three groups. The expressions of these DEMs were not only directly correlated but also exhibited potential significance in patients with PCOS and POF. Novel metabolites with up/downregulated expressions can be discovered in patients with PCOS and POF using serum-based metabolomics; these metabolites show good diagnostic performance and can act as effective biomarkers for the early detection of PCOS and POF. Furthermore, these metabolites might be involved in the pathophysiol. mechanisms of PCOS and POF via interplay with corresponding genes. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).Recommanded Product: H-Phg(4-OH)-OH

On October 12, 2017, Narku-Tetteh, Jessica; Muchan, Pailin; Saiwan, Chintana; Supap, Teeradet; Idem, Raphael published an article.Synthetic Route of 2160-93-2 The title of the article was Selection of components for formulation of amine blends for post combustion CO2 capture based on the side chain structure of primary, secondary and tertiary amines. And the article contained the following:

Side chain structure and number of OH- groups in primary, secondary, and tertiary amines effect on CO2 absorption and desorption kinetics, equilibrium loads, heat duty, cyclic capacity, heat of absorption, and pKa were assessed and used to develop rational criteria to select components to formulate an optimum amine blend. Based on these criteria, amines which had a combination of high absorption and desorption parameters were selected. Their mixing ratios and concentrations were varied to obtain best overall performance. Results showed that in comparison with their straight-chain analogs, steric hindrance present in branched-chain alkanolamines resulted in much faster desorption rate, higher CO2 solubility and cyclic capacity, and much lower heat duty for solvent regeneration, but just a slight decrease in CO2 absorption rate. Developed criteria resulted in formulating an excellent bi-solvent aqueous amine blend (comprised of 2 M BEA + 2 M AMP), shown to have outstanding desorption characteristics/heat duty and very good absorption characteristics. Also, this work developed a non-trial-and-error procedure to determine heat of CO2 absorption based on Gibbs-Helmholtz equation. It showed the CO2 absorption rate and heat of CO2 absorption may not necessarily be proportional to the heat of absorption and heat duty, resp. Both these relations were shown to be strong functions of amine structure. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Synthetic Route of 2160-93-2

On June 19, 2013, Chowdhury, Firoz Alam; Yamada, Hidetaka; Higashii, Takayuki; Goto, Kazuya; Onoda, Masami published an article.Product Details of 2160-93-2 The title of the article was CO2 Capture by Tertiary Amine Absorbents: A Performance Comparison Study. And the article contained the following:

This work assessed CO2 capture with 24 tertiary amine absorbents (including 3 synthetic amines) with systematic modification of their chem. structures. Aqueous amine solutions (30 % mass fraction) were used to evaluate CO2 capture performance. Laboratory gas scrubbing, vapor-liquid equilibrium, and reaction calorimetry experiments were conducted to obtain the absorption rate, amount of CO2 absorbed, cyclic CO2 capacity, and heat of reaction for each absorbent. Results for were compared with the conventional tertiary absorbent, N-methyldiethanolamine (MDEA). Seven of the studied absorbents performed well with high absorption rates and cyclic capacities. Among these absorbents, some displayed lower heats of reaction than MDEA. Results provided basic guidelines to discover potential tertiary amine-based absorbents which may lead to development of new absorbent systems for CO2 capture. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Product Details of 2160-93-2

On March 9, 2016, Yu, Kun; Reichard, Mikayla C.; Dai, Ning published an article.Synthetic Route of 2160-93-2 The title of the article was Nitrosamine Formation in the Desorber of Tertiary Alkanolamine-Based Carbon Dioxide Capture Systems. And the article contained the following:

Tertiary amines are being considered as absorption solvents for post-ombustion CO2 capture, but their potential to form harmful byproducts nitrosamines is yet to be evaluated. This study examined the factors affecting the formation of nitrosamines from tertiary alkanolamines under simulated desorber conditions and the effects of amine structural characteristics. Total nitrosamine formation from tertiary alkanolamine was determined to be 1st-order with respect to nitrite concentration and the absorbed CO2, but was 0-order with respect to amine concentration in the range of 0.5-2.5M. Tertiary alkanolamines formed less nitrosamine than their secondary amine analogs. For tertiary alkanolamines with the same number of 2-hydroxyethyl groups, smaller steric hindrance resulted in more nitrosamine formation and higher yields based on nitrite consumption. The anal. of specific nitrosamines revealed that the cleavage of 2-hydroxyethyl group was preferred over demethylation, but comparable to de-ethylation. Reaction pathways were proposed to account for the exptl. observations. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Synthetic Route of 2160-93-2
