| Direct uptake and rapid decrease of organic nitrogen by Wollemia nobilis |
|
Organic nitrogen (N) can be directly taken up by many plants, particularly under low-temperature and N-limited conditions. The natural environment of Wollemia nobilis, shady conditions and shallow, acidic soils with high organic matter, led to the hypothesis that organic N might be a potential N ...

| Three new ursane-type triterpenes from the leaves of Rehmannia glutinosa |
|
Three new ursane-type triterpenes, glutinosalactone A-C (1–3), were isolated from the 50% aqueous acetone extract of the leaves of Rehmannia glutinosa. Their structures were elucidated on the basis of spectral analysis (IR, NMR and MS spectroscopy). The cytotoxic effects of compounds 1–3 agai...

| Screen of Bovine Mammary Gland Epithelial Cell Specifcity Promotor |
|
Three lactoproteins (α-S1-casein, β-lactoglobulin, and β-casein) promotors were cloned, sequenced and compared relative luciferase expression. The results showed that the promotor activity of bovine α-S1-casein gene was the best, and would be used to produce pharmaceutically and medically imp...
