Abstract
As a systemic triazole fungicide, limited information is known about diniconazole. In this study, toxicological effects and bioaccumulation behavior of diniconazole in zebrafish were both evaluated to perform an overall assessment of its environmental risk towards aquatic organisms. The (1)H NMR-based metabolomics analysis revealed that 70*?g*L(-1) diniconazole exposure increased valine, leucine, isoleucine, alanine, lactate and choline, accompanied by decreased glucose, creatine and taurine, in comparison to the control. In the exposure group of 300*?g*L(-1) diniconazole, only down-regulated glucose and creatine were observed. The above results indicated that diniconazole disturbed energy metabolism, amino acid metabolism and lipid metabolism. Histological examination showed that the swell and vacuolization in the liver, as well as the reduction of spermatids in the diniconazole exposure groups. No enantioselectivity was observed in the bioaccumulation process of both 70 and 300*?g*L(-1) diniconazole exposure groups. The above results play a vital role for a comprehensive environmental assessment of diniconazole.

NMR-based metabolomics of mammalian cell and tissue cultures
NMR-based metabolomics of mammalian cell and tissue cultures Abstract NMR spectroscopy was used to evaluate growth media and the cellular metabolome in two systems of interest to biomedical research. The first of these was a Chinese hamster ovary cell line engineered to express a recombinant protein. Here, NMR spectroscopy and a quantum mechanical total line shape analysis were utilized to quantify 30 metabolites such as amino acids, Krebs cycle intermediates, activated sugars, cofactors, and others in both media and cell extracts. The impact of bioreactor scale and addition of...
