Impacts of land use change and climatic effects on streamflow in the Chinese Loess Plateau: A meta-analysis.

Land use and climate change are recognized as two major drivers affecting surface streamflow. On the Chinese Loess Plateau, implementation of several land restoration projects has changed land cover in recent decades. The main objectives of this study were to understand how streamflow evolved on the Loess Plateau and how land use and climate change have contributed to this change.

Proton nuclear magnetic resonance spectroscopy of body fluids in the field of inborn errors of metabolism.

Proton nuclear magnetic resonance (NMR) spectroscopy of body fluids has been successfully applied to the field of inborn errors of metabolism. This technique has the advantage of minimal sample pretreatment not requiring extraction or derivatization steps. Moreover, the spectrum provides a comprehensive metabolic profile of proton-containing, low-molecular-weight metabolites.

1H-NMR spectroscopy of cerebrospinal fluid of fetal sheep during hypoxia-induced acidemia and recovery.

The purpose of the study was to investigate the sequence of processes occurring during and after hypoxia-induced acidemia. We used proton nuclear magnetic resonance spectroscopy, which provides an overview of metabolites in cerebrospinal fluid (CSF), reflecting neuronal metabolism and damage. The pathophysiological condition of acute fetal asphyxia was mimicked by reducing maternal uterine blood flow in 14 unanesthetized pregnant ewes.

Prolidase deficiency diagnosed by 1H NMR spectroscopy of urine.

Three urine samples from two prolidase-deficient patients were analysed using 1H NMR spectroscopy. One-dimensional 1H NMR spectra showed a characteristic pattern of overlapping resonances of the proline and hydroxyproline protons of the imidodipeptides. The model compounds Ala-Pro, Gly-Pro, Phe-Pro, Leu-Pro, Val-Pro, Gly-Hyp and Pro-Hyp were measured as well.
