A unique strategy, in which invading microorganisms are being caught in web-like structures composed mainly of DNA, involves a recently described phenomenon called NETosis. This process seems to be related to the production of reactive oxygen species (ROS). In our study, the influence of dipheny...

Electronic absorption and emission spectra as well as He(I) photoelectron spectra of 2,2,4,4-tetramethyl-1,3-cyclobutanedithione and 2,2,4,4-tetramethyl-1-3-thio-1,3-cyclobutanedione have been interpreted on the basis of molecular orbital calculations. The results show that the non-bonded orbita...

In 2017, the Clinical and Laboratory Standards Institute (CLSI) Subcommittee on Antimicrobial Susceptibility Testing approved the use of iron-depleted cation-adjusted Mueller-Hinton broth (ID-CAMHB) prepared with Chelex® 100 resin (Bio-Rad Laboratories, Hercules, CA) to determine MICs for cefide...

In this work, we present a simple two-step synthesis route to develop a cost effective high performance Ti3C2Mn3O4 nanocomposite via a solvothermal process at 150 °C. The characterization of the composite material was obtained via various techniques. Electrochemical performance study of the mat...

The environmental implications of graphene oxide (GO) have received much attention. Transport of GO in subsurface environment is a critical process affecting the migration and potential risks of this important class of carbonaceous nanomaterials. To date, the effects of heterogeneity in porous m...

Electrodialysis is an electrochemically driven membrane technology usually used for treating feed water containing several thousand mg/l total dissolved solids (TDS). This research investigated the use of conventional ED for the treatment of flowback water from shale gas hydraulic fracturing tha...

The reaction of tricarbonyl and (dicarbonyl)triphenylphosphine (1-methoxycarbonyl-pentadientyl)iron(1+) cations 7 and 8 with methyl lithium, NaBH3CN, or potassium phthalimide affords (pentenediyl)iron complexes 9a-c and 11a-b, while reaction with dimethylcuprate, gave (E,Z-diene)iron complexes 1...

The iron-ore-based catalysts (IO-CAT) with catalytic properties similar to those of conventional precipitated iron-based catalysts (PFe-CAT) were successfully prepared through a combination of a wet-milling process and a wet impregnation method. This approach was much more economical and eco-fri...

Piroxicam is a potent anti-inflammatory and antipyretic drug, which also has a protective action against different oxidative agents. Nevertheless, it also induces adverse side effects and it is considered as new emerging contaminant. An advanced oxidation process, Fenton chemistry, was chosen as...

SummaryCisplatin is classically known to exhibit anticancer activity through DNA damage in the nucleus. Here we found a mechanism by which cisplatin affects iron metabolism, leading to toxicity and cell death. Cisplatin causes intracellular iron deficiency through direct inhibition of the master...

Divalent iron and zinc cations can be removed from water by electrocoagulation (EC) with aluminium electrodes in a discontinuous system: the effect of hydrocarbonate HCO3- ion often present in liquid waste and in groundwater on the EC process has been investigated. For the two ions, the presence...

Iron element is one of the main impurities in wet-process phosphoric acid and it has a significant impact on the subsequent phosphorus chemical products. This paper studied the feasibility of using Sinco-430 cation exchange resin for iron removal from phosphoric acid. The specific surface area a...

Toxicity of eight 22,23-dihydroxystigmastane derivatives (four pairs of (22R,23R)- and (22S,23S)-isomers differing in steroid backbone structure) to human breast carcinoma MCF-7 cells was compared. For every pair of structurally related compounds, (22R,23R) isomer was found to be significantly m...

For million years resin exudates have undergone chemical alterations by heat, pressure, radiation, water, oxygen, microorganisms, and have suffered processes of sedimentation and diagenesis. These agents have affected the organic functional groups present in the terpenes of the resins, giving ri...

First amino bis(picolyl) and amino bis(quinaldinyl) phosphines were synthesized by reaction of the corresponding amino dichlorophosphines – the new carbazolyl dichlorophosphine (1) and diisopropylamino dichlorophosphine (2) with either picolylTMS (6), quinaldinylTMS (15) or their respective lit...

Treatment of the diiron hexacarbonyl complexes (μ-SCH2CH2CH2S-μ)Fe2(CO)6 or [μ-SCH(CH3)CH(CH3)S-μ]Fe2(CO)6 with 1,2-bis(diphenylphosphino)acetylene in the presence of Me3NO·2H2O afforded tetrairon complexes with a bridging diphosphine ligand [(μ-SCH2CH2CH2S-μ)Fe2(CO)5]2(Ph2PCCPPh2) (1) an...

Quinolinic acid, α-picolinic acid, fusaric acid, and 2,6-pyridinedicarboxylic acid enhanced the Fenton reaction in phosphate buffer, respectively. The enhancement by quinolinic acid, α-picolinic acid, fusaric acid, and 2,6-pyridinedicarboxylic acid of the Fenton reaction may be partly related ...
