(2007)Two polymorphic forms of a mixed zinc/copper biquinoline dihydrogenphosphate are presented, showing almost identical monomeric units, viz. (2,2 '-biquinoline-kappa N-2,N ')bis(dihydrogenphosphato-kappa O)copper(II)/zinc(II), ...
-
(American Society for Microbiology, 2013-04)Salmonella enterica serotype Gallinarum is the causative agent of fowl typhoid, a disease characterized by high morbidity and mortality that causes major economic losses in poultry production. We have reported that S. ...
-
(PLOS ONE, 2013)The role of the Salmonella Pathogenicity Islands (SPIs) in pathogenesis of Salmonella enterica Typhimurium infection in the chicken is poorly studied, while many studies have been completed in murine models. The Type VI ...
-
(Taylor & Francis, 2018)UHPLC/ESI/MS identification of organic compounds is the first step in the majority of screening techniques for the characterization of biologically active metabolites in natural sources. This paper describes a method for ...
-
(MDPI, 2021)Gaultheria pumila (Ericaceae) (known as Chaura or Mutilla) is a Chilean native small shrub that produces berry fruits consumed by local Mapuche people. In this study, the chemical fingerprinting and antioxidant, enzyme ...
-
(Elsevier, 2015)A novel analytical approach involving an improved rotating-disk sorptive extraction (ROSE) procedure and ultra-high-performance liquid chromatography (UHPLC) coupled to an ultraspray electrospray ionization source (UESI) ...
-
(ELSEVIER, 2006-11-03)In the present work the efficiency of extraction of aliphatic diesel range organics (DROs) and polycyclic aromatic hydrocarbons (PAHs) from soil was assessed by using dynamic modes of pressurized solvent extraction (PSE), ...
-
(JOHN WILEY & SONS LTD, 2009-06)The polar Diels-Alder (DA) reactions of 2-acetyl-1,4-benzoquinone (acBQ) with methyl substituted 1,3-butadienes have been studied using DFT methods at the B3LYP/6-31 G(d) level of theory. These reactions are characterized ...
-
Une méthode simple pour le traitement des filtres employés dans l'etude des aerosols atmosphériques. (Akadémiai Kiadó, 1982)A simple and rapid method for the multielement routine analysis of atmospheric particulate matter is described. The samples collected on four different types of filters were treated with HNO3 and HCl at 110-120 ºC in pyrex ...
-
(2005)1,4-dihydropyridine derivatives constitute an important pharmacological group for the treatment of cardiovascular diseases. We have synthesised a series 4-(5′-nitro-2′-furyl)-1,4-dihydropyridine derivatives, which were ...

(SOC BRASILEIRA QUIMICA, 2005-01)1,4-dihydropyridine derivatives constitute an important pharmacological group for the treatment of cardiovascular diseases. We have synthesised a series 4-(5'-nitro-2'-furyl)-1,4-dihydropyridine derivatives, which were ...
-
(AMER CHEMICAL SOC, 2005-10-28)Photoreduction of oxoisoaporphine dyes occurs via a stepwise mechanism of electron-protonelectron transfer that leads to the N-hydrogen oxoisoaporphine anion. When triethylamine, TEA, was used as the electron donor in ...
-
(The American Society of Photobiology, 2013)Photoinduced electron transfer between N-phenylglycine (NPG) and electronically excited triplets of 7-substituted-3- methyl-quinoxalin-2-ones in acetonitrile generate the respective ion radical pair, where by decarboxylation ...
-
(Royal Society of Chemistry, 2019)New 4-amino-3-iminoquinoline derivative ligands (L1-4) were synthesized through an intramolecular exo-dig cyclization of anionic β-diketiminates, containing an N-benzonitrile moiety. The effect of the alkali-metal in this ...
-
(Wiley-Blackwell, 2015)To obtain mechanistic insights into the cross talk between lipolysis and autophagy, two key metabolic responses to starvation, we screened the autophagy-inducing potential of a panel of fatty acids in human cancer cells. ...
-
(Elsevier, 2015)A new series of unsymmetrical cyrhetrenyl and ferrocenyl azines that were monosubstituted [(η5-C5H4)– C(R)_N–N_CH(5-NO2–2-C4H2O)]M {with M_Re(CO)3 and R_H (1a) or R_Me (1b); M_Fe(η5-C5H5) and R_H (2a) or R_Me (2b)} and ...
