On April 30, 2022, Hu, Jingrun; Qi, Dianqing; Chen, Qian; Sun, Weiling published an article.Product Details of 144-80-9 The title of the article was Comparison and prioritization of antibiotics in a reservoir and its inflow rivers of Beijing, China. And the article contained the following:

The occurrence of antibiotics in drinking water resources, like reservoirs, is of considerable concern due to their potential risks to ecosystem, human health, and antimicrobial resistance development. Here, we quantified 83 antibiotics in water and sediments of wet and dry seasons from the Miyun reservoir and its inflow rivers in Beijing, China. Twenty-four antibiotics were detected in water with concentrations of ND-11.6 ng/L and 19 antibiotics were observed in sediments with concentrations of ND-6.50 ng/g. Sulfonamides (SAs) were the dominated antibiotics in water in two seasons. SAs and quinolones (QNs) in wet season and macrolides (MLs) and QNs in dry season predominated in sediments. The reservoir and inflow rivers showed significant differences in antibiotic concentrations and compositions in water and sediments. As an important input source of reservoir, the river water showed significantly higher total antibiotic concentrations than those in the reservoir. In contrast, the reservoir sediments are the sink of antibiotics, and had higher total antibiotic concentrations compared with rivers. A prioritization approach based on the overall risk scores and detection frequencies of antibiotics was developed, and 3 (sulfaguanidine, anhydroerythromycin, and sulfamethoxazole) and 5 (doxycycline, sulfadiazine, clarithromycin, roxithromycin, and flumequine) antibiotics with high and moderate priority, resp., were screened. The study provides a comprehensive insight of antibiotics in the Miyun Reservoir and its inflow rivers, and is significant for future monitoring and pollution mitigation of antibiotics. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Product Details of 144-80-9

Benth.Ex baker seeds in vivo and in vitro.HPLC of Formula: 456-12-2 And the article contains the following content:

The leguminosae of Sophora moorcroftiana (Benth.) Benth.ex Baker is a drought-resistant endemic Sophora shrub species from the Qinghai-Tibet Plateau, and its seeds have hepatoprotective effects. To study the effect of S. moorcroftiana seeds on liver injury and the mol. mechanism underlying the beneficial effects, liquid chromatog.-mass spectrometry was used to detect the main active components in the ethanol extract of S. moorcroftiana seeds (SM). Male mice were divided into six groups (n = 8): normal control (NC), CCl4, SM (50, 100, 200 mg/kg), and di-Me di-Ph bicarboxylate (150 mg/kg) groups. Mice were treated as indicated (once/day, orally) for 14 days, and CCl4 (2 mL/kg) was administered i.p. The serum and liver of mice were used for biochem. assays. To explore the underlying mechanism, HepG2 cells were treated with SM, stimulated with tert-Bu hydroperoxide (t-BHP, 50 渭M), and analyzed by Western blotting. The major active compounds of SM were alkaloids including 22 compounds Serum alanine transaminase (ALT), aspartate transaminase (AST), and alk. phosphatase (ALP) decreased in the SM (200 mg/kg) group. SM can activate the expression of pregnane X receptor (PXR) and downstream mols. cytochrome P 4503A11 enzyme (CYP3A11), UDP glucuronosyltransferase 1 family polypeptide A 1 (UGT1A1), and inhibit the multidrug resistance protein 2 (MRP2). In addition, SM improved cell viability in t-BHP-induced HepG2 cells (64% to 83%) and decreased the activation of the mitogen-activated protein kinase (MAPK) pathway. The main compounds in SM were alkaloids. SM showed hepatoprotective effects possibly mediated by the suppression of oxidative stress through the MAPK pathway. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).HPLC of Formula: 456-12-2

Antibiotic (蟽sulfonamide, 蟽fluoroquinolone, 蟽tetracycline and 蟽macrolide) contamination in aquatic systems has remained a global concern in recent years. In this study, fourteen antibiotics, sulfadiazine (SDZ), sulphapyridine (SPD), sulfacetamide (SCT), sulfamethoxazole (SMX), sulfamethazine (SMZ), trimethoprim (TMP), ofloxacin (OFX), lomefloxacin (LFX), ciprofloxacin (CFX), norfloxacin (NFX), oxytetracycline (OTC), tetracycline (TC), dehydroerythromycin (ETM-H2O) and roxithromycin (RTM), were analyzed in zooplankton collected from the Yelang Lake Reservoir between May 2016 and Mar. 2017. Our results demonstrated that the antibiotic TC (mean 95.80 ng g-1), OTC (mean 167.0 ng g-1) and RTM (mean 151.80 ng g-1) concentrations were significantly higher in zooplankton than the other antibiotics. TC, OTC and RTM accumulated intensively in zooplankton, and the BAFs of OTC, RTM and TC were significantly higher, with mean BAF values of 78.43, 108.4 and 110.1, resp. Antibiotic concentrations were strongly correlated with zooplankton phytoplankton biomass, OTC, RTM and SMX concentrations in zooplankton were significantly pos. correlated with bacillariophyte biomass, and SDZ and SMZ concentrations in zooplankton were significantly pos. correlated with T. brevifurcatus, T. mongolicus, and D. pulex biomass. SPD with P. tunguidus, C. cornuta, TMP, ETM and OFX with P. tunguidus, C. cornuta, M. leuckarti, C. vicinus vicinus, CFX with D. pulex, LFX with T. brevifurcatus, T. mongolicus, Bosmina longirostris, and D. dubium were significantly pos. correlated. These results show that bioaccumulation or scavenging of antibiotics across trophic levels is a fundamental and complex component of antibiotic cycling in aquatic environments. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Application of 144-80-9

Zheng, Guihua; Yang, Yiyi; Deng, Linghui; Zhang, Ting; Zhu, Feiyun; Sun, Jing; Li, Shuangjiang; Feng, Xiaonan published an article in 2022, the title of the article was Pollution status and health impact assessment of antibiotics in environmental – and drinking water.Electric Literature of 144-80-9 And the article contains the following content:

The problem of antibiotics pollution in environmental water and drinking water has attracted the attention of environmental protection departments and all walks of life. At present, antibiotics have been widely detected in many water systems, and the concentration range is from ng/L to pg/L. In this paper, a method for the anal. of antibiotics in water by high performance liquid chromatog. tandem mass spectrometry (HPLC-MS/MS) was established. Then, the risk quotient (HQ) of antibiotics in wastewater treatment plant effluent and river water was calculated and studied. The results showed that some antibiotics did not cause direct ecol. risk. Finally, the health risk assessment of environmental water and drinking water was carried out. The results showed that the non carcinogenic risk caused by antibiotic pollution in the reservoir was far lower than the acceptable risk level, even far lower than the negligible risk level, indicating that the residues of these antibiotics in the drinking water would not pose significant non carcinogenic harm to human body.

On December 16, 2021, Shi, Wei; Tiwari, Surya P.; Thompson, Robert L.; Culp, Jeffrey T.; Hong, Lei; Hopkinson, David P.; Smith, Kathryn; Resnik, Kevin; Steckel, Janice A.; Siefert, Nicholas S. published an article.Recommanded Product: 1,3-Diphenylurea The title of the article was Computational Screening of Physical Solvents for CO2 Pre-combustion Capture. And the article contained the following:

A computational scheme was used to screen phys. solvents for CO2 pre-combustion capture by integrating the com. NIST database, an inhouse computational database, chem-informatics, and mol. modeling. A com. available screened hydrophobic solvent, di-Et sebacate, was identified from the screening with favorable phys. properties and promising absorption performance. The promising performance to use di-Et sebacate in CO2 pre-combustion capture has also been confirmed from experiments Water loading in di-Et sebacate is very low, and therefore, water is kept with H2 in the gas stream. The favorable CO2 interaction with di-Et sebacate and the intermediate solvent free volume fraction leads to both high CO2 solubility and high CO2/H2 solubility selectivity in di-Et sebacate. An inhouse NETL computational database was built to characterize CO2, H2, N2, and H2O interactions with 202 different chem. functional groups. It was found that 13% of the functional groups belong to the strong interaction category with the CO2 interaction energy between -15 and -21 kJ/mol; 62% of the functional groups interact intermediately with CO2 (-8 to -15 kJ/mol). The remaining 25% of functional groups interact weakly with CO2 (below -8 kJ/mol). In addition, calculations show that CO2 interactions with the functional groups are stronger than N2 and H2 interactions but are weaker than H2O interactions. The CO2 and H2O interactions with the same functional groups exhibit a very strong linear pos. correlation coefficient of 0.92. The relationship between CO2 and H2 gas solubilities and solvent fractional free volume (FFV) has been systematically studied for seven solvents at 298.2 K. A skewed bell-shaped relation was obtained between CO2 solubility and solvent FFV. When an organic compound has a d. approx. 10% lower than its d. at 298.2 K and 1 bar, it exhibits the highest CO2 loading at that specific solvent d. and FFV. Note that the solvent densities were varied using simulations, which are difficult to be obtained from the experiment In contrast, H2 solubility results exhibit an almost perfect pos. linear correlation with the solvent FFV. The theor. maximum and min. phys. CO2 solubilities in any organic compound at 298.2 K were estimated to be 11 and 0.4 mol/MPa L, resp. An examination of 182 exptl. CO2 phys. solubility data and 29 simulated CO2 phys. solubilities shows that all the CO2 phys. solubility data are within the maximum and min. with only a few exceptions. Finally, simulations suggest that in order to develop phys. solvents with both high CO2 solubility and high CO2/H2 solubility selectivity, the solvents should contain functional groups which are available to interact strongly with CO2 while minimizing FFV.

This study established a detection method based on accelerated solvent extraction-liquid chromatog.-mass spectrometry for determining residues of 3 chloramphenicols, 8 macrolides, 18 sulfonamides, 4 nitroimidazoles, 15 insecticides, and 22 fungicides in poultry feathers. The extraction solvent, methanol, was used for a static extraction time of 5 min, and repeated three times. Fifty milligrams of adsorbents C18/PSA (1 : 1, W/W) were added to the extraction cell to achieve simultaneous extraction and purification The extraction efficiency of three solvents, methanol, acetonitrile and Et acetate, was investigated. An orthogonal exptl. design was used to explore the optimal combination of extraction temperature, static extraction time, number of extraction cycles, and adsorbent ratio for accelerated solvent extraction After the optimal ratio was determined, the dosage of adsorbents was optimized. The extracted sample solution was concentrated by blowing nitrogen, redissolved, passed through a 0.22 渭m PTFE membrane filter, then injected for instrumental anal. The validation results showed that the recovery of the proposed method was 60.4-107.6%, the limit of detection 0.2-3.0 渭g kg-1, and the limit of quantification 0.5-8.3 渭g kg-1. This quant. multi-residue detection method was able to determine the residues of 70 target compounds in poultry feathers.
