Strigolactones (SLs) are a group of newly identified plant hormones that control plant shoot branching. SL signalling requires the hormone-dependent interaction of DWARF 14 (D14), a probable candidate SL receptor, with DWARF 3 (D3), an F-box component of the Skp-Cullin-F-box (SCF) E3 ubiquitin ligase complex. Here we report the characterization of a(More)
The effects of Li(+) and polyethylene glycol (PEG) on the genetic transformation of Saccharomyces cerevisiae were investigated by using fluorescence microscopy (FM) to visualize the binding of plasmid DNA labeled with YOYO-1 to the surface of yeast cells, scanning electron microscopy (SEM) and atomic force microscopy (AFM) to image the change in surface(More)
The secretory pathway of eukaryotic cells packages cargo proteins into COPII-coated vesicles for transport from the endoplasmic reticulum (ER) to the Golgi. We now report that complete genetic deficiency for the COPII component SEC24A is compatible with normal survival and development in the mouse, despite the fundamental role of SEC24 in COPII vesicle(More)
Previous studies on diabetes have reported controversial results with regard to transporters in liver. The present study aimed to explore changes in hepatic breast cancer resistance protein (BCRP) expression and functions, as well as the possible underlying mechanisms, in type 2 diabetic patients, type 1 (streptozotocin-induced), and type 2 (Goto Kakizaki)(More)
A new method based on fluorescence imaging and flow cytometry was developed to investigate the transformation process of Saccharomyces cerevisiae AY. Yeast and fluorescent-labeled plasmid pUC18 were used as models of cells and DNA molecules, respectively. Binding of DNA molecules to yeast cell surfaces was observed. Factors influencing DNA binding to cell(More)
Neuroblastoma is a common childhood malignant tumor originated from the neural crest-derived sympathetic nervous system. A crucial early event in neuroblastoma pathogenesis is arrested differentiation of neuroblasts at various stages. Treatment of neuroblastoma with TPA and PDGF-BB leads to terminal differentiation of neuroblastoma cells. However, the(More)
A rational screening of cyclodextrin-based polymer (CDP), in terms of the relationship between adsorption potential and adsorbent-adsorbate, was investigated to adsorb and separate pesticides from water. Seven spherical porous CDPs were prepared with onefold or composite cyclodextrin(s) as complex and epichlorohydrin as cross-linking reagent. The adsorption(More)
OBJECTIVE To understand the nutritional level of lactating mothers and infant by detecting the content of the vitamin B1, vitamin B2, vitamin B6, nicotinic of milk of urban and rural areas and to provide the basis for improving vitamin nutritional status of lactating women and their babies. METHODS Totally 92 pairs of breastfeeding healthy mothers and(More)
Gracilaria lemaneiformis was exposed to 0, 25, 50, 100, 250 and 500 microg x L(-1) of Cu2+ to study its physiological responses to Cu2+ stress. When the Cu2+ concentration was > or = 50 microg x L(-1), the relative growth rate (RGR) of G. lemaneiformis decreased significantly, and the optimal quantum yield (Fv/Fm), the maximum relative electron transfer(More)
Oxidized low-density lipoprotein (ox-LDL) is involved in the pathogenesis of atherosclerosis and atherosclerotic plaque rupture by promoting lipid accumulation, proinflammatory responses, and cell death. LDL is mainly oxidized in the subendothelial layer of the vascular wall and then can be taken up by vascular endothelial cells. However, little is known(More)
