Mechanism and plasticity of isochorismate pyruvate lyase: a computational study
(American Chemical Society, 2009)
The isochorismate pyruvate lyase (IPL) from Pseudomonas aeruginosa, designated as PchB, catalyzes the transformation of isochorismate into pyruvate and salicylate, but it also catalyzes the rearrangement of chorismate into ...
Oxygen Atom Transfer Reactions from Mimoun Complexes to Sulfides and Sulfoxides. A Bonding Evolution Theory Analysis
(American Chemical Society, 2014-07)
In this research, a comprehensive theoretical investigation has been conducted on oxygen atom transfer (OAT) reactions from Mimoun complexes to sulfides and sulfoxides. The joint use of the electron localization function ...
Isostructural Second-Order Phase Transition of β-Bi2O3 at High Pressures: An Experimental and Theoretical Study
(American Chemical Society, 2014-09)
We report a joint experimental and theoretical study of the structural and vibrational properties of synthetic sphaerobismoite (β-Bi2O3) at high pressures in which room-temperature angle-dispersive X-ray diffraction (XRD) ...
Screening of antibiotics in surface and wastewater samples by ultra-high-pressure liquid chromatography coupled to hybrid quadrupole time-of-flight mass spectrometry
(Elsevier, 2009)
The potential of ultra-high-pressure liquid chromatography (UHPLC) coupled to hybrid quadrupole time-of-flight mass spectrometry (QTOF-MS) for the screening and confirmation of antibiotics in water samples is illustrated ...
Determination of melamine in milk-based products and other food and beverage products by ion-pair liquid chromatography-tandem mass spectrometry
(Elsevier, 2009)
This paper describes a fast method for the sensitive and selective determination of melamine in a wide range of food matrices, including several milk-based products. The method involves an extraction with aqueous 1% ...
Raw milk composition and sanitary quality after summer in semi-arid region
(Schlütersche Verlagsgesellschaft, 2021)
The purpose of the present study was to evaluate physicochemical characteristics, milk coagulation properties and microbiological contents afterward the hot season to understand the impacts on raw milk quality. Fifty milk ...
Potentiated Electron Transference in a-Ag2WO4 Microcrystals with Ag Nanofilaments as Microbial Agent
(American Chemical Society, 2014-02)
This study is a framework proposal for understanding the antimicrobacterial effect of both α-Ag2WO4 microcrystals (AWO) synthesized using a microwave hydrothermal (MH) method and α-Ag2WO4 microcrystals with Ag metallic ...
Improvements in analytical methodology for the determination of frequently consumed illicit drugs in urban wastewater
(Springer, 2014-07)
Rapid and sensitive analytical methodology based on ultra high-performance liquid chromatography-tandem mass spectrometry has been developed for the determination of widely consumed drugs of abuse (amphetamines, MDMA, ...
Quantum Mechanics/Molecular Mechanics Studies of the Mechanism of Falcipain-2 Inhibition by the Epoxysuccinate E64
(American Chemical Society, 2014-05)
Because of the increasing resistance of malaria parasites to antimalarial drugs, the lack of highly effective vaccines, and an inadequate control of mosquito vectors, the problem is growing, especially in the developing ...
Determination of methylisothiocyanate in soil and water by HS-SPME followed by GC-MS-MS with a triple quadrupole
(Springer, 2014-09)
Methylisothiocyanate (MITC) is the main degradation product of metam sodium, a soil disinfectant widely used in agriculture, and is responsible for its disinfectant properties. Because MITC is highly toxic and volatile, ...
