Parahydrogen and Synthesis Allow Dramatically Enhanced Nuclear Alignment
TL;DR: The PASADENA effect as mentioned in this paper is a method for transient high-sensitivity proton spin-labelling by molecular addition of dihydrogen, which can be converted to magnetization observable by NMR.
Journal ArticleDOI
Comparison of structural and chemical properties of black and red human hair melanosomes
Yan Liu,Lian Hong,Kazumasa Wakamatsu,Shosuke Ito,Bhavin Adhyaru,Chi Yuan Cheng,Clifford R. Bowers,John D. Simon +7 more
TL;DR: Different yields of 4-amino-hydroxyphenolanaline by HI hydrolysis and pyrrole-2,3,5-tricarboxylic acid by KMnO4/H+ oxidation indicate that the melanosomes in black hair are eumelanosome, whereas those in red hair are mainly pheomelanosomes.
Journal ArticleDOI
High-resolution, >1 GHz NMR in unstable magnetic fields.
TL;DR: It is shown that modern stabilization and shimming technology, combined with detection of intermolecular zero-quantum coherences (iZQCs), can remove almost all of the effects of inhomogeneity and drifts, while retaining chemical shift differences and J couplings.
Journal ArticleDOI
High capacity production of >65% spin polarized xenon-129 for NMR spectroscopy and imaging.
TL;DR: To achieve production of 129Xe gas at even higher polarization will rely on further optimization of the pumping cell and laser beam geometries in order to mitigate problems associated with temperature gradients that are encountered at high laser power and Rb density.
Journal ArticleDOI
Comparisons of the Structural and Chemical Properties of Melanosomes Isolated from Retinal Pigment Epithelium, Iris and Choroid of Newborn and Mature Bovine Eyes¶
Yan Liu,Lian Hong,Kazumasa Wakamatsu,Shosuke Ito,Bhavin Adhyaru,Chi Yuan Cheng,Clifford R. Bowers,John D. Simon +7 more
TL;DR: Observations suggest that the 5,6-dihydroxyindole-2-carboxylic acid contents decrease in the following order: choroid > iris > RPE, and decrease with age, and 13C solid-state NMR spectra show an increase in the concentration of carbonyl groups with age within each type of melanosome.
