In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria and alternatives is the most important aspect in the MADM. Criteria were divided into two c...

Recombinant peptide synthesis allows for large-scale production of peptides with therapeutic potential. However, access to dicarba peptidomimetics via sidechain-deprotected sequences becomes challenging exposed Lewis basicity presented by amine and sulfur-containing residues. Presented here is a combination strategies which can be used deactivate coordinative residues achieve high-yielding Ru-c...

abstract background: esophageal replacement is indicated in certain circumstances including long gap esophageal atresia, severe strictures due to gastro-esophageal reflux (ger) and caustic burns. we analyzed our results of 18 patients who underwent esophageal replacement in our university hospital. methods: we reviewed esophageal replacements carried out in our department between june 1996 and ...

It is well known that small amount Piperazine (PZ) enhance the CO2 absorption properties of tertiary amine aqueous solution. Because the tert-amine has the lower heat of reaction, the blended amine solution, tert-amine with PZ, is attractive for low energy absorbent. There are some reports about the investigation of the mechanism of the blended amine solution, however, there still a difficulty ...

BACKGROUND We previously identified renalase, a secreted novel amine oxidase that specifically degrades circulating catecholamines. Parenteral administration of either native or recombinant renalase lowers blood pressure, heart rate, and cardiac contractility by metabolizing circulating catecholamines. Renalase plasma levels are markedly reduced in patients with chronic kidney disease. It is no...

in this paper, we report on the synthesis of cu nanoparticles through a single-precursor route by controlling the growth temperature. selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. the understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...

Amine-modified mesoporous SBA-15 adsorbent has been prepared by impregnation method using tetraethylenepentamine. The samples of this modified SBA-15 have been characterized by small angle X-ray scattering (SAXS), Scanning electron microscopy (SEM), Nitrogen adsorption-desorption isotherm and FT-IR. The adsorption capacity of CO2 on unmodified and modified samples were measured at high pressure...

Novel 2-(4-aminophenyl)benzothiazoles (e.g., compounds 1 and 2) possess highly selective, potent antitumor properties in vitro and in vivo. Elucidation of the mechanism of action of this structurally simple class of compounds has occurred in parallel with selection of a candidate clinical agent. Antitumor benzothiazoles induce and are biotransformed by cytochrome P 450 1A1 to putative active, a...

The mechanism of sulfonamide cleavage of PNU-109112, a potent HIV-1 protease inhibitor, by glutathione-S-transferase (GST) was investigated in the presence of reduced GSH. GST-catalyzed sulfonamide cleavage takes place via the nucleophilic attack of GSH on the pyridine moiety of the substrate with formation of the GS-para-CN-pyridinyl conjugate, the corresponding amine, and sulfur dioxide. Stru...

Oil (healthier lipid combination of olive, linseed and fish oils)-in-water emulsions stabilized with different protein systems (prepared with sodium caseinate (SC), soy protein isolate (SPI), and microbial transglutaminase (MTG)) were used as pork backfat replacers in low-fat frankfurters. Microstructure, lipid oxidation, nitrite content, microbiological changes and biogenic amine formation of ...
