The large-scale use of antibiotics is causing serious water pollution problems, and it is of great significance to develop new technologies to remove antibiotics from water. As an environmentally friendly and economical adsorption material, carbon derived from biomass is a low-cost and feasible material for removing antibiotics in sewage, but the current removal efficiencies are not high enough for large-scale practical application. In this study, poplar wood chips are used as raw material, and a magnetic biochar is prepared by co-pyrolysis of poplar wood chips and FeCl₃/CaCl₂ mixed molten salt. X-ray diffraction (XRD), Fourier transform IR spectroscopy (FTIR), N2-isothermal adsorption and desorption, XPS and scanning electron microscope (SEM) techniques showed the successful synthesis of Fe₂O₃/bioC composite. In-situ formed Fe₂O₃ makes the biochar possess the characteristic of superparamagnetic, which is conducive to the recycling of biochar. Due to the etching effect of the molten salts, rough surface was formed on Fe₂O₃/bioC, resulting in a maximum norfloxacin (NOR) adsorption ability up to 38.77 mg g^-1 at pH 6.0. The NOR adsorption behavior on Fe₂O₃/bioC followed the pseudo second order kinetic model and the equilibrium data was best fitted the Langmuir model. In addition, the adsorption process of NOR on Fe₂O₃/bioC was thermodynamically spontaneous. The results show that this low-cost and reusable magnetic biochar has the potential for rapid and efficient removal of antibiotic from aqueous solution This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Safety of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid).

1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. Piperazine is a fairly basic compound and is an amine solvent.

Improvement of the pharmacokinetics and antifibrotic effects of nintedanib by intrapulmonary administration of a nintedanib-hydroxypropyl-γ-cyclodextrin inclusion complex in mice with bleomycin-induced pulmonary fibrosis was written by Togami, Kohei;Ogasawara, Arisa;Irie, Sayo;Iwata, Kenji;Yamaguchi, Kotaro;Tada, Hitoshi;Chono, Sumio. And the article was included in European Journal of Pharmaceutics and Biopharmaceutics in 2022.Synthetic Route of C33H39N5O7S The following contents are mentioned in the article:

Idiopathic pulmonary fibrosis is a chronic lung disease that is characterized by progressive abnormal reprogramming following injury of the pulmonary structure. In this study, we prepared a nintedanib (antifibrotic agent) and cyclodextrin (CyD) inclusion complex to improve the pharmacokinetics and antifibrotic effects of nintedanib following intrapulmonary administration. Hydroxypropyl-γ-CyD (HP-γ-CyD) enhanced the solubility of nintedanib without cytotoxic effects on WI-38 cells (lung fibroblasts) and NCI-H441 cells (alveolar epithelium model). Compared with nintedanib ethanesulfonate salt, the nintedanib-HP-γ-CyD inclusion complex exhibited prolonged distribution in the lungs following intrapulmonary administration in mice with bleomycin-induced pulmonary fibrosis. In addition, compared with nintedanib ethanesulfonate salt, the nintedanib-HP-γ-CyD inclusion complex exhibited higher stability in the bronchoalveolar lavage fluid and lower permeability in NCI-H441 cell monolayers. These results suggested that the inclusion complexation of nintedanib into HP-γ-CyD improved its pharmacokinetics following intrapulmonary administration by increasing its stability in the lungs and reducing its permeability through the alveolar cell membrane. Intrapulmonary administration of the nintedanib-HP-γ-CyD inclusion complex significantly reduced the intrapulmonary hydroxyproline content and limited pathol. fibrotic changes. Overall, this study indicates that antifibrotic agent-CyD inclusion complexation intended for intrapulmonary administration can be used to prolong distribution in the lungs and lead to the expansion of idiopathic pulmonary fibrosis therapy.

ROS as a key player in quinolone antibiotic stress on Arabidopsis thaliana: From the perspective of photosystem function, oxidative stress and phyllosphere microbiome was written by Jin, Ming-Kang;Yang, Yu-Tian;Zhao, Cai-Xia;Huang, Xin-Rong;Chen, Han-Mei;Zhao, Wen-Lu;Yang, Xiao-Ru;Zhu, Yong-Guan;Liu, Hui-Jun.

With the increasing use of antibiotics, their ecol. impacts have received widespread attention. However, research on the toxicity of quinolone antibiotics is still limited, especially regarding the oxidative stress and phyllosphere of plants. In this study, the toxic effects of enrofloxacin, norfloxacin, and levofloxacin on Arabidopsis thaliana and their underlying mechanisms were investigated. The toxicity of the three quinolone antibiotics decreased in the following order: enrofloxacin > norfloxacin > levofloxacin. Physiol. cellular changes, such as plasmolysis and chloroplast swelling, were observed using electron microscopy. Photosynthetic efficiency was inhibited with a decline in the effective photochem. quantum yield of photosystem II (Y(II)) and non-photochem. quenching (NPQ), indicating that quinolone antibiotics might reduce light energy conversion efficiency and excess light energy dissipation. Oxidative stress occurred in A. thaliana after quinolone antibiotic treatment, with an increase in reactive oxygen species (ROS) levels and malondialdehyde (MDA) content. High ROS levels stimulated the over-expression of superoxide-responsive genes for self-protection. Structural equation modeling (SEM) anal. showed that photosynthesis inhibition and cellular damage caused by oxidative stress were critical factors for growth inhibition, suggesting that the antioxidant response activated by ROS might be a potential mechanism. Furthermore, the diversity of the phyllospheric microbial communities decreased after enrofloxacin exposure. Addnl., specific microbes were preferentially recruited to the phyllosphere because of the higher ROS levels. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Quality Control of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid).

Detection of Extended-Spectrum Beta-Lactamases (ESBLs) depends on screening for resistance to certain cephalosporins, confirmation with selective ESBL inhibitors, and ESBL genes detection. New tests are required for accurate ESBL detection. To test the ability of cefixime (CFM) and cefixime-amoxicillin/clavulanate (CFM-AMC) as a screening and confirmatory test for ESBL identification. 246 Clin. isolates of Escherichia coli were tested by an ESBL screening test, a double-disk synergy test (DDST), a disk replacement test, the Vitek 2 ESBL test, and an ESBL genes test by PCR. CFM ESBL Screening was performed by disk diffusion, while CFM-AMC confirmation was performed by DDST and a disk replacement test. 246 E. coli clin. isolates from two referral hospitals were collected over 2 years. The mean age ± standard deviation of patients was 43.8 ± 27.7 years and 76.8% were females. Resistance rates to penicillins, first, second, and third generation cephalosporins, and monobactams were very high at 97%, 84%, 100% and 97%, resp. ESBL screening was pos. in 81.3% of isolates, DDST was pos. in 74.8%, disk replacement was pos. in 79%, Vitek 2 ESBL test was pos. in 67.3%, and ESBL genes were detected in 85.8% of isolates (CTX-M 75%, TEM 42.5%, SHV 4.6%). Compared to genotyping, screening with CFM achieved 87.7% sensitivity and 64.7% specificity. CFM-AMC DDST achieved 75.8% sensitivity and 75.4% specificity, and CFM-AMC disk replacement had 73% sensitivity and 70% specificity. High prevalence of ESBLs was noted among E. coli isolates, dominated by CTX-M genotype. ESBL screening and confirmation using CFM and CFM-AMC is a new and accurate method for ESBLs detection.

Cadmium (Cd) directly endangers poultry health and indirectly causes harm to human health by food chain. Numerous studies have focused on removing Cd using lactic acid bacteria (LAB). However, there is still a lack of in vivo studies to validate whether Cd can be absorbed successfully by LAB to alleviate Cd toxicity. Here, we aimed to isolated and screened poultry-derived Cd-tolerant LAB with the strongest adsorption capacity in vitro and investigate the protective effect of which on sub-chronic Cd toxicity in chickens. First, nine Cd-tolerant LAB strains were selected preliminarily by isolating, screening, and identifying from poultry farms. Next, four strains with the strongest adsorption capacity were used to explore the influence of different phys. and chem. factors on the ability of LAB to adsorb Cd as well as its probiotic properties in terms of acid tolerance, bile salt tolerance, drug resistance, and antibacterial effects. Resultantly, the CLF9-1 strain with the best comprehensive ability was selected for further animal protection test. The Cd-tolerant LAB treatment promoted the growth performance of chickens and reduced the Cd-elevated liver and kidney coefficients Moreover, Cd-induced liver, kidney, and duodenum injuries were alleviated significantly by high-dose LAB treatment. Furthermore, LAB treatment also increased the elimination of Cd in feces and markedly reduced the Cd buildup in the liver and kidney. In summary, these findings determine that screened Cd-tolerant LAB strain exerts a protective effect on chickens against sub-chronic cadmium poisoning, thus providing an essential guideline for the public health and safety of livestock and poultry.

The activation of hydrogen peroxide (H₂O₂) by Fe/carbon composites has been widely used for the removal of antibiotics. However, the secondary pollution of iron ions limits the application of Fe²⁺/H₂O₂ system. In this work, three kinds of hydrogel materials combining metal-organic framework (MOF)-derived magnetic Fe/porous carbon (MagFePC) with sodium alginate (SA), polyacrylic acid (PAA) and agarose (AG) were prepared by different methods for removal of norfloxacin (NOR) antibiotics in simulated wastewater. After comparison, MagFePC/SA hydrogels synthesized by a titration forming method were found to have the advantages of good toughness, abundant pores and best Fenton activity. MagFePC/SA can effectively activate H₂O₂ to remove NOR under neutral conditions, and there was almost no leaching of iron ions, causing no secondary pollution to the environment. The effects of pH, ionic strength and surfactants on the degradation performance for NOR were studied. Mechanism study revealed that ·O^–₂ and ¹O₂ were the main active species for the degradation of NOR, and the materials still had good stability and reusability after repeated cycles. More important, we built a simple automated unit for wastewater treatment under laboratory conditions that can completely degrade a 5 mg/L NOR solution at a flow rate of 2 mL/min. Current works showed that MagFePC/SA had the advantages of simple synthesis, outstanding degradability, excellent stability and eco-friendly reaction, which was a wastewater treatment material with good prospect for industrial application.

Emission of antibiotics into riverine environments affects aquatic ecosystem functions and leads to the development of antibiotic resistance. Here, the profiles of forty-four antibiotics and eighteen antibiotic resistance genes (ARGs) were analyzed in two large rivers of the Pearl River System. In addition, the risks of ecotoxicity and resistance selection posed by the antibiotics were estimated As compared to the reservoirs, the river sections close to the urban and livestock areas contained more antibiotics and ARGs. Seasonal variations of antibiotics (higher in the dry season) and relative ARGs (normalized by 16S rRNA gene, higher in the wet season) were found in the water, but not in the sediment. Sulfonamide resistance genes were the most prevalent ARGs in both river water and sediment. Antibiotic concentration was correlated with ARG abundance in the water, indicating that antibiotics play a critical role in ARG spread. In addition, oxytetracycline was the most abundant antibiotic with concentrations up to 2030 ng/L in the water and 2100 ng/g in the sediment resp., and posed the highest risks for resistance selection. Oxytetracycline, tetracycline and sulfamethoxazole were expected to be more ecotoxicol. harmful to aquatic organisms, while ofloxacin, enrofloxacin, norfloxacin, chlortetracycline, oxytetracycline and tetracycline posed ecotoxicol. risks in the sediment. The Nanliujiang river with intensive livestock activities was contaminated by antibiotics and ARGs and faced high ecotoxicol. and resistance selection risks. Collectively, these findings reflect the impacts of anthropogenic activities on the spread of antibiotic resistance in large river basins.

Acute exacerbation during the course of idiopathic pulmonary fibrosis causes a poor prognosis. Coagulation abnormalities and endothelial damage are involved in its pathogenesis. Thrombomodulin alfa, a recombinant human soluble thrombomodulin, has anticoagulant and antiinflammatory effects. Several clin. studies have shown that thrombomodulin alfa may improve survival of acute exacerbation. To determine the efficacy and safety of thrombomodulin alfa compared with placebo in acute exacerbation of idiopathic pulmonary fibrosis. This randomized, double-blind placebo-controlled phase 3 study conducted at 27 sites in Japan involved patients with an acute exacerbation of idiopathic pulmonary fibrosis. Subjects were randomized 1:1 to receive placebo or thrombomodulin alfa (380 U/kg/d for 14 d by i.v. drip infusion). All subjects were treated with high-dose corticosteroid therapy. The primary endpoint was the survival proportion on Day 90. Of the 82 randomized subjects, 77 completed the study and were included in the full anal. set (thrombomodulin alfa, n = 40; placebo, n = 37). The survival proportions on Day 90 were 72.5% (29 of 40) in the thrombomodulin alfa group and 89.2% (33 of 37) in the placebo group, a difference of 216.7 percentage points (95% confidence interval, 233.8 to 0.4%; P = 0.0863). In the safety population (n = 80), bleeding adverse events occurred in the thrombomodulin alfa group (10 of 42; 23.8%) and the placebo group (4 of 38; 10.5%). Thrombomodulin alfa did not improve the 90-day survival proportion. The present results suggest that the use of thrombomodulin alfa for the treatment of acute exacerbation of idiopathic pulmonary fibrosis not be recommended.

Sewage treatment plants are an essential source of antibiotics, antibiotic resistance determinants, and bacteria in environmental waters. However, it is still unclear whether they can maintain a relatively stable relationship in wastewater and environmental waters. This study analyzed the removal capacity of the above three pollutants in the sewage treatment plant in summer and their impact on environmental waters, and then examines the relationship between the three contaminants in the wastewater and environmental waters in summer and winter based on our previous study. The results found that the removal capacity of bacteria in summer was poor, the concentration of fluoroquinolone in the effluent was higher than that in influent, and the abundance of intI1, tetW, qnrB, and ermB increased after wastewater treatment. Proteobacteria and Bacteroides were the main bacteria that constitute the correlation network between bacteria, and they existed stably in summer and winter. However, fluoroquinolones occupied a significant position in the determinant network of antibiotics and antibiotic resistance in summer and winter. There are fewer correlation between antibiotics and antibiotics resistance determinants in winter. Interestingly, the relationship between bacteria, antibiotics, and antibiotic resistance determinants was a mainly pos. correlation in summer and neg. correlation in winter. This study analyzed the relationship between bacteria, antibiotics, and antibiotic resistance determinants that were stable in the wastewater and environmental waters and pointed out the direction for subsequent targeted seasonal control of novel pollutants in wastewater and environmental waters.

Insight into the existent state of nitrogen-doped carbon dots in titanate nanotubes and their roles played toward simultaneous removal of coexisted Cu²⁺ and norfloxacin in water was written by Kang, Li;Yang, Hanpei;Yu, Haibo;Wu, Qiangshun. And the article was included in Journal of Colloid and Interface Science in 2022.Name: 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid The following contents are mentioned in the article:

In this work, nitrogen-doped carbon dots (NCDs) were introduced in different existent sites of titanate nanotubes (TNTs) by a facile synthesis, and their effects on surface potential, photoelectrochem. properties and simultaneous removal of coexisted Cu²⁺ and norfloxacin (NOR) performance in water were systematically investigated. Constructed NCDs-TNTs composite displayed superior performance towards the adsorption (ion exchange/coordination) of Cu²⁺ and adsorption-oxidization of NOR over the two individuals, mainly benefiting from the collaboration of NCDs in different existent states. The existence of Ti-N-H chem. linkage was identified between TNTs and NCDs-OT (NCDs on the outer surface of TNTs), which not only modulates the surface potential to favor the external diffusion of Cu ²⁺ or NOR⁺ from aqueous solution to the neg. charged NCDs-TNTs, but also facilitates the intraparticle transfer of contaminants to the reactive sites. In addition, the up-conversion light property of NCDs-OT and the interstitial NCDs-IT (NCDs on the inner surface of TNTs) doping in TNTs interact together to enable NCDs-IT-TNTs to fully absorb and utilize all visible light. The photoexcited electrons were further trapped by NCDs-OT to promote the photogenerated carrier separation Adsorbed Cu²⁺ could also improve the performance of NCDs-TNTs toward NOR oxidization, mainly owing to the self-synchronous doping of adsorbed Cu ²⁺ broadening light absorption area and acting as mediators for delivering electrons. This work provides unique insights into the structural design of composite materials for such combined contamination remediation in water.
