Exploring High-resolution Magic Angle Spinning (HR-MAS) NMR Spectroscopy for Metabonomic Analysis of Apples

Classical liquid-state high-resolution (HR) NMR spectroscopy has proved a powerful tool in the metabonomic analysis of liquid food samples like fruit juices. In this paper the application of (1)H high-resolution magic angle spinning (HR-MAS) NMR spectroscopy to apple tissue is presented probing its potential for metabonomic studies. The (1)H HR-MAS NMR spectra are discussed in terms of the chemical composition of apple tissue and compared to liquid-state NMR spectra of apple juice. Differences indicate that specific metabolic changes are induced by juice preparation. The feasibility of HR-MAS NMR-based multivariate analysis is demonstrated by a study distinguishing three different apple cultivars by principal component analysis (PCA). Preliminary results are shown from subsequent studies comparing three different cultivation methods by means of PCA and partial least squares discriminant analysis (PLS-DA) of the HR-MAS NMR data. The compounds responsible for discriminating organically grown apples are discussed. Finally, an outlook of our ongoing work is given including a longitudinal study on apples.

Exploring Magic Realism in Salman Rushdie's Fiction

Kluwick breaks new ground in this book, moving away from Rushdie studies that focus on his status as postcolonial or postmodern, and instead considering the significance of magic realism in his fiction. Rushdie’s magic realism, in fact, lies at the heart of his engagement with the post/colonial. In a departure from conventional descriptions of magic realism—based primarily on the Latin-American tradition—Kluwick here proposes an alternative definition, allowing for a more accurate description of the form. She argues that it is disharmony, rather than harmony, that is decisive: that the incompatibility of the realist and the supernatural needs to be recognized as a driving force in Rushdie’s fiction. In its rigorous analysis of this Rushdian magic realism, this book considers the entire corpus—Midnight’s Children, Shame, The Satanic Verses, The Moor’s Last Sigh, The Ground Beneath Her Feet, Shalimar the Clown, and The Enchantress of Florence. This study is the first of its kind to do so.
