Composition, Antibacterial and Antioxidant Activities of Essential Oils from Ligusticum sinense and L. jeholense (Umbelliferae) from China
The essential oils were obtained by hydro-distillation from the roots and rhizomes of two umbelliferous species Ligusticum sinense and L. jeholense. They were analyzed for their chemical composition by GC and GC-MS. 5-Oxo-δ-4-decahydrobenzindene (50.1%), ligustilide (16.4%), β-phellandrene (7.8%), myristicine (5.5%), and spathulenol (3.3%) were the major compounds of the 25 identified component...
متن کاملB chromosomes in Brazilian rodents.
B chromosomes are now known in eight Brazilian rodent species: Akodon montensis, Holochilus brasiliensis, Nectomys rattus, N. squamipes, Oligoryzomys flavescens, Oryzomys angouya, Proechimys sp. 2 and Trinomys iheringi. Typically these chromosomes are heterogeneous relative to size, morphology, banding patterns, presence/absence of NORs, and presence/absence of interstitial telomeric signals af...

The search for viable eBusiness models continues. But important information is being overlooked. Discussions of open source software all too often focus on the limited context of Microsoft appearing to feel threatened by what it portrays as unbusinesslike competition from Linux and OpenOffice.org; whereas that debate is merely one small facet of the whole. Moreover, in addition to software, a g...
متن کاملAurora B puts chromosomes in their place
Aurora B puts chromosomes in their place mall molecule inhibitors of Aurora B activity, characterized by Hauf et al. (page 281) and Ditchfield et al. (page 267), reveal that the mammalian kinase and its budding yeast counterpart, Ipl1, have similar functions. Without Aurora B, mistakes in kinetochore–chromosome interactions go uncorrected. Early evidence of a function for the Aurora family in c...
متن کاملTranscriptionally active heterochromatin in rye B chromosomes.
B chromosomes (Bs) are dispensable components of the genomes of numerous species. Thus far, there is a lack of evidence for any transcripts of Bs in plants, with the exception of some rDNA sequences. Here, we show that the Giemsa banding-positive heterochromatic subterminal domain of rye (Secale cereale) Bs undergoes decondensation during interphase. Contrary to the heterochromatic regions of A...
