Amiodarone, an antiarrhythmic drug toxic toward the lung, is metabolized through sequential modifications of the diethylaminoethoxy group to mono-N-desethylamiodarone (MDEA), di-N-desethylamiodarone (DDEA), and amiodarone-EtOH (B2-O-EtOH), whose effects on lung cells are unclear. To clarify this, we exposed rabbit alveolar macrophages to analogs with different modifications of the diethylaminoe...

Poly(ethylene-co-propylene-co-diene) (EPDM) containing 50 wt% of poly(ethylene-co-propylene) grafted with maleic anhydride (EP-g-MA) has been melt blended with poly(styrene-co-acrylonitrile) (SAN) added with various amounts of reactive SAN, i.e. SAN bearing either primary amine (SAN-NH2) or carbamate groups (SAN-carb). Carbamate groups are precursors of primary amines by thermal thermolysis dur...

A 15-kb region of Pseudomonas putida chromosomal DNA containing the mde operon and an upstream regulatory gene (mdeR) has been cloned and sequenced. The mde operon contains two structural genes involved in L-methionine degradative metabolism: the already-identified mdeA, which encodes L-methionine gamma-lyase (H. Inoue, K. Inagaki, M. Sugimoto, N. Esaki, K. Soda, and H. Tanaka. J. Biochem. (Tok...

The MEA Polycomb gene is imprinted in the Arabidopsis endosperm. DME DNA glycosylase activates maternal MEA allele expression in the central cell of the female gametophyte, the progenitor of the endosperm. Maternal mutant dme or mea alleles result in seed abortion. We identified mutations that suppress dme seed abortion and found that they reside in the MET1 methyltransferase gene, which mainta...

In this work, the performance of an amine-based post-combustion carbon capture system using MEA (monoethanolamine) integrated to a Waste-to-Energy (WtE) plant is studied. WtE plants are affected by fluctuations at different time-scales, due changes in waste properties as well variations district heat demand. A dynamic model combined used study effect flue gas on operation, and integrating into ...

Given the significance of dissolved H2S, various techniques have been explored in literature. The current review describes detail membrane-based techniques, such as membrane contactors, for removing H2S from wastewater streams. Various types hydrophobic membranes used, with more emphasis placed on PVDF hollow fiber membranes. do not allow water to pass through, whereas is readily allowed throug...

Capture and sequestration of CO2 from fossil fuel power plants is gaining widespread interest as a potential method of controlling greenhouse gas emissions. Performance and cost models of an amine (MEA)-based CO2 absorption system for postcombustion flue gas applications have been developed and integrated with an existing power plant modeling framework that includes multipollutant control techn...

Ultrasonic Irradiation (UI) is an emerging technology that used to assist the CO 2 absorption process. Even for slow kinetic solvents without using any chemical promoter, high-frequency UI might enhance mass transfer during For this purpose, it essential study performance of a ultrasonic-assisted system under varied operating conditions. The ultrasonic power considered as one main parameters . ...
