Ciprofloxacin-degrading Paraclostridium sp. isolated from sulfate-reducing bacteria-enriched sludge: Optimization and mechanism

Ciprofloxacin (CIP), one of the most widely used fluoroquinolone antibiotics, is frequently detected in the effluents of wastewater treatment plants and aquatic environments. In this study, a CIP-degrading bacterial strain was isolated from the sulfate reducing bacteria (SRB)-enriched sludge, identified as Paraclostridium sp. (i.e., strain S2). The effects of critical operational parameters on CIP removal by the strain S2 were systematically studied and these parameters were optimized via response surface methodology to maximize CIP removal. Furthermore, the pathway and kinetics of CIP removal were investigated by varying the initial CIP concentrations (from 0.1 to 20 mg/L). The CIP removal was characterized by rapid sorption followed by biotransformation with a specific biotransformation rate of 1975.7 +/- 109.1 mu g/g-cell dry weight/h at an initial CIP concentration of 20 mg/L. Based on the main transformation products, several biotransformation pathways have been proposed including piperazine ring cleavage, OH/F substitution, decarboxylation, and hydroxylation as the major transformation reactions catalyzed by cytochrome P450 and dehydrogenases. Acute toxicity assessment apparently shows that CIP biotransformation by strain S2 resulted in the formation of less toxic intermediates. To the best of our knowledge, this is the very first study in which a key functional microbe, Paraclostridium sp., highly effective in CIP biotransformation, was isolated from SRB-enriched sludge. The findings of this study could facilitate in developing appropriate bioaugmentation strategy, and in designing and operating an SRB-based engineered process for treating CIP-laden wastewater.

The interfacial degradation mechanism of polymer:fullerene bis-adduct solar cells and their stability improvement

Although fullerene bis-adducts have been widely used in polymer solar cells for their high LUMO energy level and good performance, the degradation behavior of this class of solar cells has not been well understood. In this paper, the performance and stability of the solar cells based on P3HT:fullerene bis-adducts, including bis-PC61BM and ICBA, were systematically investigated. Different from the P3HT:PC61BM cell, these bis-adduct based cells showed fast open circuit (V-OC) and fill factor (FF) decays. The partial recovery of V-OC and FF of the aged cells by renewing the MoO3/Al electrode indicated that degradation at the photoactive layer and MoO3 interface is the main reason for V-OC and FF decays. The X-ray photoelectronic spectroscopy analysis confirmed that under light illumination, Mo6+ of MoO3 is partially reduced to Mo5+. By inserting a thin layer of C-60, both MoO3 reduction and performance decays are slowed down, confirming that photoreduction of MoO3 by P3HT is the degradation mechanism for P3HT:bis-PC61BM cells. Finally, we found that doping a polymer:fullerene bis-adduct layer with piperazine increases the fullerene content on the surface of the photoactive layer, which consequently lowers the reduction of Mo6+ and improves the stability of the solar cells. This work gives a detailed understanding of the interfacial degradation of PSCs and provides effective solutions, which has important guiding significance for improving the stability of different types of polymer solar cells.

Ruta chalepensis L. Essential Oil Has a Biological Potential for a Natural Fight against the Pest of Stored Foodstuffs: Tribolium castaneum Herbst

Chemical pesticides used against insect pests of stored food have adverse effects on both health and the environment. So, the present study aims to evaluate the insect repulsive and insecticidal power ofRuta chalepensisL. essential oil (EO) from the region of Oulmes (Central plateau of Morocco); the ultimate objective is to develop a biological and ecological control strategy against pests. Thus, the EO obtained by hydrodistillation from the aerial parts ofRuta chalepensisL. was identified by GC-MS; its repellent and fumigant toxicity effects on adults ofTribolium castaneumHerbst were, respectively, investigated by the preferential area method on a filter paper and the inhalation test. The insecticide power was estimated by determining the percentage of mortality as a function of the duration of exposure and concentration of the EO. The essential oil obtained is characterized by the dominance of 2-undecanone (64.35%), piperonyl piperazine (11.9%), 2-decanaone (5.12%), 2-dodecanone (4.52%), decipidone (3.9%,) and 2-tridecanone (2.36%). This EO is endowed with a very repulsive power belonging to class V, which is strongly due to its majority compound 2-undecanone. The dose 0.038 mu l/ml gave a repellent power of 100% after 15 min. The tests also revealed a considerable insecticidal effect, which reached 100% after 48 hours at a dose of 0.62 mu l/ml. The calculation of the lethal dose causing 50% mortality (LD50) and the lethal times after which there is 50% mortality (LT50) allowed deducing that the insecticidal effect ofRuta chalepensisL. is time- and dose-dependent. Hence, the effectiveness ofRuta chalepensisL. EO attests that it can constitute a healthy alternative to fight againstTribolium castaneumHerbst.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 111974-74-4 is helpful to your research. SDS of cas: 111974-74-4.

Preparation of monoamine-incorporated polyamide nanofiltration membranes by interfacial polymerization for efficient separation of divalent anions from divalent cations

For the purpose of efficient separation of sulfate ions from magnesium ions, novel negatively-charged nanofiltration membranes were developed by incorporating the monoamines 4-aminobenozic acid, aniline-2,5-disulfonic acid monosodium salt, and iminodiacetic acid (IDA) during interfacial polymerization of piperazine (PIP) and trimesoyl chloride. PIP-amide membranes without these monomers tended to reject magnesium ions as well as sulfate ions. In contrast, incorporation of the monoamines resulted in large molecular weight cut-offs and large negative charge densities thanks to carboxyl or sulfo terminal groups of the monoamines, which enabled preferential permeation of magnesium ions while maintaining high rejection of sulfate ions. In particular, the IDA-incorporated nanofiltration membrane with an IDA to PIP + IDA mass ratio of 0.40 showed high rejection of sulfate ions with low rejection of magnesium ions even when the concentration of sodium chloride was much higher than that of magnesium sulfate. This result indicates the feasibility of the developed membrane for magnesium recovery from desalinated seawater in the electrodialysis process for table salt production.

Synthesis, in vitro evaluation and molecular docking of a new class of indolylpropyl benzamidopiperazines as dual AChE and SERT ligands for Alzheimer’s disease

During the last decade, the one drug-one target strategy has resulted to be inefficient in facing diseases with complex ethiology like Alzheimer’s disease and many others. In this context, the multitarget paradigm has emerged as a promising strategy. Based on this consideration, we aim to develop novel molecules as promiscuous ligands acting in two or more targets at the same time. For such purpose, a new series of indolylpropyl-piperazinyl oxoethyl-benzamido piperazines were synthesized and evaluated as multitarget-directed drugs for the serotonin transporter (SERT) and acetylcholinesterase (AChE). The ability to decrease beta-amyloid levels as well as cell toxicity of all compounds were also measured. In vitro results showed that at least four compounds displayed promising activity against SERT and AChE. Compounds 18 and 19 (IC50 = 3.4 and 3.6 mu M respectively) exhibited AChE inhibition profile in the same order of magnitude as donepezil (DPZ, IC50 = 2.17 mu M), also displaying nanomolar affinity in SERT. Moreover, compounds 17 and 24 displayed high SERT affinities (IC50 = 9.2 and 1.9 nM respectively) similar to the antidepressant citalopram, and significant micromolar AChE activity at the same time. All the bioactive compounds showed a low toxicity profile in the range of concentrations studied. Molecular docking allowed us to rationalize the binding mode of the synthesized compounds in both targets. In addition, we also show that compounds 11 and 25 exhibit significant beta-amyloid lowering activity in a cell-based assay, 11 (50% inhibition, 10 mu M) and 25 (35% inhibition, 10 mu M). These results suggest that indolylpropyl benzamidopiperazines based compounds constitute promising leads for a multitargeted approach for Alzheimers disease. (C) 2020 Elsevier Masson SAS.

Immobilized piperazine on the surface of graphene oxide as a heterogeneous bifunctional acid-base catalyst for the multicomponent synthesis of 2-amino-3-cyano-4H-chromenes

Immobilized piperazine on the surface of graphene oxide (piperazine-GO) is synthesized and characterized by different methods such as FT-IR, solid-state(29)Si{H-1} and(13)C{H-1} CP/MAS NMR, elemental analysis, TGA, TEM, FE-SEM, XPS, and TPD. Subsequently, it is used as a heterogeneous bifunctional acid-base catalyst for the efficient multicomponent reaction of malononitrile, different active compounds containing enolizable C-H bonds and various aryl/alkyl aldehydes in aqueous ethanol. A wide variety of 2-amino-3-cyano-4H-chromenes are synthesized in the presence of this heterogeneous catalyst in good to high yields and with short reaction times. The catalyst is easily separated and reused for at least six times without significant loss of activity. The acidic nature of GO improves the catalytic activity of the supported piperazine and also provides heterogeneity to the catalyst. Use of aqueous ethanol as a green solvent, high turnover numbers (TON), facile catalyst recovery and reuse, simple work-up and generality of the method make this protocol an environmentally benign procedure for the synthesis of the title heterocycles.

A highly sensitive biosensor with a single-copy evolved sensing cassette for chlorpyrifos pesticide detection

A formylglycine-generating enzyme (FGE)-sulfatase-based whole cell biosensor was genetically improved into a single copy system by integrating the Sinorhizobium meliloti transcriptional activator ChpR and the chpA promoter-FGE-sulfatase fusion into the Escherichia coli chromosome. The sensitivity was further enhanced through a random mutagenesis of the chpR. The new integrated biosensor offered both a lower detection limit [5 nM chlorpyrifos (CPF)] and fluorescence background. The ready to use kit was developed using silica gel for on field detection. The biosensor kit was stable for 20 days when stored at 4 degrees C. Moreover, a 1-(1 naphthylmethyl)piperazine (NMP) efflux pump inhibitor can improve the sensitivity by 57%.

Serotonergic-linked alterations of aggression of the crayfish

Current theory suggests that aggressive behavior in the crayfish is largely modulated and regulated by the neurotransmitter serotonin (5-HT). To test this theory that links serotonin to aggression, we performed a series of drug treatments using various serotonin-related chemicals to measure their effects on subsequent aggressive behavior. Treatments included serotonin, the serotonin precursor tryptophan, agonists: 1-(3-chlorophenyl) piperazine (m-CPP) and 5-Carboxy, an antagonist: cinanserin, and a serotonin receptor specific neurotoxin: 5,7-dihydroxytryptamine creatinine sulfate (5,7-DHT). Significant increases in aggression ofFaxonius rusticuscrayfish were observed when injected with serotonin and both agonists, however no decrease in aggression occurred with the antagonist. Crayfish injected with the agonist m-CPP increased aggression but did not directly confer success in fights. Our data support the current literature that the internal aggressive state of crayfish is altered by serotonin and its agonist/antagonists, however it does not on its own improve the aggressive fighting response and/or dominance status.

Degradation mechanism of norfloxacin in water using persulfate activated by BC@nZVI/Ni

In this work, biochar-supported nano zero-valent iron/nickel bimetallic composite (BC@nZVI/Ni) was synthesized using liquid phase reduction method and used to activate persulfate (PS) to degrade norfloxacin (NOR) in water. The synthesized BC@nZVI/Ni was characterized using scanning electron microscope (SEM), X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS). The effects of various reaction parameters, such as mass ratio of nZVI/Ni to BC, PS concentration, initial pH value, temperature, humic acid and the inorganic anions on NOR degradation were investigated using the system of nZVI/Ni/PS. The results showed that the system of nZVI/Ni/PS showed the higher degradation efficiency. The quenching experiments and EPA analysis manifested that center dot SO4- was the predominant radical species in acidic and neutral conditions, while center dot OH played an important role in alkaline environment. Matrix-assisted laser desorption-ionization time of flight mass spectrometry (MALDI-TOF MS) analysis illustrated that NOR can be degraded through multiple routes, such as decarboxylation, defluorination and cleavage of piperazine ring in the presence of center dot SO4- and center dot OH. These results demonstrated that nZVI/Ni/PS process was a promising strategy for treating norfloxacin-containing wastewater.

The Psychonauts’ World of Cognitive Enhancers

Background There is growing availability of novel psychoactive substances (NPS), including cognitive enhancers (CEs) which can be used in the treatment of certain mental health disorders. While treating cognitive deficit symptoms in neuropsychiatric or neurodegenerative disorders using CEs might have significant benefits for patients, the increasing recreational use of these substances by healthy individuals raises many clinical, medico-legal, and ethical issues. Moreover, it has become very challenging for clinicians to keep up-to-date with CEs currently available as comprehensive official lists do not exist. Methods Using a web crawler (NPSfinder(R)), the present study aimed at assessing psychonaut fora/platforms to better understand the online situation regarding CEs. We compared NPSfinder(R)entries with those from the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) and from the United Nations Office on Drugs and Crime (UNODC) NPS databases up to spring 2019. Any substance that was identified by NPSfinder(R)was considered a CE if it was either described as having nootropic abilities by psychonauts or if it was listed among the known CEs by Froestl and colleagues. Results A total of 142 unique CEs were identified by NPSfinder(R). They were divided into 10 categories, including plants/herbs/products (29%), prescribed drugs (17%), image and performance enhancing drugs (IPEDs) (15%), psychostimulants (15%), miscellaneous (8%), Phenethylamines (6%), GABAergic drugs (5%), cannabimimetic (4%), tryptamines derivatives (0.5%), and piperazine derivatives (0.5%). A total of 105 chemically different substances were uniquely identified by NPSfinder(R). Only one CE was uniquely identified by the EMCDDA; no CE was uniquely identified by the UNODC. Conclusions These results show that NPSfinder(R)is helpful as part of an Early Warning System, which could update clinicians with the growing numbers and types of nootropics in the increasingly difficult-to-follow internet world. Improving clinicians’ knowledge of NPS could promote more effective prevention and harm reduction measures in clinical settings.
