O10: Real-time magnetic resonance cine imaging with compressed sensing and iterative reconstruction for ventricular measures: comparison with gold-standard segmented steady-state free precession Gabriel Camargo, Leticia R Sabioni, Thomas Doring, Ralph Strecker, Maria Eduarda Derenne, Vania M Naue, Tamara Rothstein, Michaela Schmidt, Michael O Zenge, Mariappan S Nadar, Ronaldo S Lima, Ilan Gottlieb

Studies with C-2-labelled glycine and alanine in model systems containing 2,3-butanedione, glyceraldehyde or glyoxal have indicated that imidazoles and oxazoles can be formed from a-dicarbonyl compounds through Strecker reaction and subsequent formation of a-amino carbonyl reactive intermediates. These intermediates can react with any aldehyde in the reaction mixture to form an imine which in t...

The activation of chiral titanium(IV) complexes with additives, phenolic N-oxides, is found to provide an alternative strategy for asymmetric cyanosilylation of ketones in excellent yield with up to 82% ee. 2004 Elsevier Ltd.

The reactivity of a trisubstituted alkene surfactant (8-methylnon-7-ene-1 sulfonate, 1) to airborne singlet oxygen in a solution containing E. coli was examined. Surfactant 1 was prepared by a Strecker-type reaction of 9-bromo-2-methylnon-2-ene with sodium sulfite. Submicellar concentrations of 1 were used that reacted with singlet oxygen by an "ene" reaction to yield two hydroperoxides (7-hydr...

UNLABELLED Cocoa beans were alkalized before or after roasting and made into cocoa liquor before analyzing by SIFT-MS. In both alkalized-before-roasting and alkalized-after-roasting samples, there were significantly higher concentrations of alkylpyrazines for the samples with pH above 7 than pH below 7. At pH 8, the concentrations of 2,3-, 2,5-, and 2,6-dimethylpyrazine (DMP), 2,3,5-trimethylpy...

The metabolite 3-deoxyglucosone (3-DG) is formed by carbohydrate caramelisation or the Maillard reaction. 3-DG a precursor in Strecker reaction forming beer ageing compounds, such as 2-methylbutanal 3-methylbutanal. Although known intermediate, recent studies have focused on beer. Foremost, thermal load during wort boiling provides best conditions for formation and degradation, however, reactiv...

The conversion of rac -phenylglycinonitrile by different variants the nitrilase from Pseudomonas fluorescens EBC191 (EC 3.5.5.1) was studied and amounts chiral composition formed phenylglycine amide compared. Muteins that converted to extraordinarily high or were tested for chemoenzymatic enantioselective one-pot synthesis ( R )- S )-phenylglycine amide. combined initial step in traditional che...
