Comparative study on intestinal metabolism and absorption in vivo of ginsenosides in sulphur-fumigated and non-fumigated ginseng by ultra performance liquid chromatography quadruple time-of-flight mass spectrometry based chemical profiling approach.
Drug Test. Anal. 7(4) , 320-30, (2015) Our previous study indicated that sulphur-fumigation of ginseng in post-harvest handling processes could induce chemical transformation of ginsenosides to generate multiple ginsenoside sulphur derivat... |

Preparation and in vitro antioxidant activities of 6-amino-6-deoxychitosan and its sulfonated derivatives.
Biopolymers 103 , 539-49, (2015) The 6-amino-6-deoxychitosan (NC) and their 2, 6-di-N-sulfonated derivatives were prepared via N-phthaloylation, tosylation, azidation, hydrazinolysis, reduction of azide groups and N-sulfonation, and ... |

Ligand regulation of a constitutively dimeric EGF receptor.
Nat. Commun. 6 , 7380, (2015) Ligand-induced receptor dimerization has traditionally been viewed as the key event in transmembrane signalling by epidermal growth factor receptors (EGFRs). Here we show that the Caenorhabditis elega... |
