To understand the molecular and cellular mechanisms underlying the salt response and to isolate differentially expressed genes, we constructed a forward subtractive cDNA library from Salsola ferganica treated with 600 mM NaCl for different lengths of time (0, 4, 8, 12, 16, 24, 36 h) using the suppression subtractive hybridization (SSH) technique. This SSH(More)
[1] Recent studies of the northeastern part of the Tibetan Plateau have called attention to two emerging views of how the Tibetan Plateau has grown. First, deformation in northern Tibet began essentially at the time of collision with India, not 10–20 Myr later as might be expected if the locus of activity migrated northward as India penetrated the rest of(More)
Ginsenoside, the major active component in Panax ginseng, which has been used in traditional Chinese medicine, contains a series of derivatives of the triterpene dammarane being attached by some sugar moieties. To clarify the relationship between the structure of ginsenoside and its properties, 11 individual ginsenosides, along with the central structures(More)
Many studies have focused on the free-radical-initiated peroxidation of membrane lipid, which is associated with a variety of pathological events. Panax ginseng is used in traditional Chinese medicine to enhance stamina and capacity to deal with fatigue and physical stress. Many reports have been devoted to the effects of ginsenosides, the major active(More)
Structure and association of asphaltenes from coal direct hydroliquefaction were studied by fluorescence spectrometry and UV-Vis absorption spectrometry in this paper. The results indicate that asphaltene is aromatic mixtures mainly containing naphthalene nucleus and shows strong fluorescent characteristic. The forming of exciplex between asphaltene and(More)
To improve the operational stability and reusability of an epoxide hydrolase (EH) for the biosynthesis of optically active epoxides. A covalently immobilization strategy was employed to improve the stability of Agrobacterium radiobacter EH by using ethylenediamine (EDA)-functionalised epoxy resin LX-1000EP as carrier. Under the optimal conditions, the(More)
