Gas chromatography±mass spectrometry (GC±MS) and GC±MS±MS analyses of heavy oils from Bolivar Coastal Fields (Lagunillas Field) show a complete set of demethylated tricyclic terpanes. As is the case for the 25-norhopanes, the demethylated tricyclics are probably formed in reservoirs by microbially-mediated removal of the methyl group from the C-10 position, generating putative 17-nor-tricyclic ...

RNA PROCESSING FACTOR1 (RPF1) and RPF2 are pentatricopeptide repeat (PPR) proteins involved in 5' processing of different mitochondrial mRNAs in Arabidopsis (Arabidopsis thaliana). Both factors are highly similar to RESTORERS OF FERTILITY (RF), which are part of cytoplasmic male sterility/restoration systems in various plant species. These findings suggest a predominant role of RF-like PPR prot...

Japan as a folk medicine for the treatment of female disorders. This compound exhibited significant and selective inhibitory activity against HIV replication in H9 lymphocytes (EC50= 0.798 mgmL ) compared with noninfected H9 lymphocytes (EC50> 25 mgmL ), which amounts to a therapeutic index (TI) of greater than 31.3. Furthermore, biyouyanagin A strongly inhibited lipopolysaccharide (LPS)-induce...
