      In China, ginseng root began to be used in medicine over 2000 years ago. And its use is gaining popularity in the western world. Ginsenosides are the most important component isolated from ginseng. The authors investigated the effect of ginsenoside Rg1 on the spectrum of gene expression in the endothelial cells stimulated by TNF-alpha, and further explored the potential molecular mechanism of endothelial protection by ginsenoside Rg1.

      This paper challenges the appropriateness of the current clinical guideline to give clopidogrel, a drug aimed to preventing recurrent ulcer, to patients who have substantial gastrointestinal intolerance of aspirin.

      The authors of this paper have made a new organic thin film (H2 rotaxane) as a new recording medium. By applying a positive or negative voltage from a STM tip 'dots' can be written or erased. The authors show that these dots, visible using AFM, are the result of conductance transitions in the H2 rotaxane molecules.

  • Ru-Catalyzed Asymmetric Hydrogenation of Racemic Aldehydes via Dynamic Kinetic Resolution: Efficient Synthesis of Optically Active Primary Alcohols

    • J.-H. Xie, Z.-T. Zhou, W.-L. Kong, Q.-L. Zhou

      Asymmetric hydrogenation of R-branched aldehydes still remains a challenge to chemists. The products of this - chiral alcohols - would be of use industrially and in academia for a wide range of applications. The authors of this paper have used a catalyst previously developed by themselves - [RuCl2(SDPs)(diamine)] ? to obtain a single alcohol enantiomer by dynamic kinetic resolution.

  • High precision measurements of Mg/Ca and Sr/Ca ratios in carbonates by cold plasma inductively coupled plasma quadrupole mass spectrometry

      Mg/Ca and Sr/Ca ratios in foraminiferal carbonates are regularly used by marine geochemists to reconstruct past ocean temperature. The authors of this paper present a new analytical method for the measurement of the trace levels of these elements by ICP-QMS. Previous problems such as interferences from 86Sr have been addressed and furthermore the method uses small amounts of sample - an important achievement given the laborious hand picking of microscopic foraminifera samples. Modern temperatures calculated from foraminiferal Mg/Ca from the South China Sea are close to those measured instrumentally. Analysis of glacial and interglacial foraminifera yields a sea surface temperature change of 3 degrees C.

      The authors have modelled land use change in China for the years 2039, 2069 and 2099. Under a particular climate change scenario, they find that cultivated land would decrease and woodland would expand greatly, in line with expectations by implementing the Grain-for-Green policy.

      Long lasting X-ray flares can be explained by a new model. This involves differentially rotating, millisecond pulsars after the mergers of binary neutron stars
