Development of microsatellite markers for the dove tree, Davidia involucrata (Nyssaceae), a rare endemic from China.

Premise Of The Study: Microsatellite primers were developed for the endangered Davidia involucrata to assess the population genetics and infer its evolutionary history.

Methods And Results: Using both the modified magnetic bead hybridization method and the dual-suppression PCR method, we isolated and characterized 12 polymorphic microsatellite loci using 134 individuals from five populations in southwestern China. The number of alleles per locus ranged from six to 21 (mean = 10.

[Inhibitory action of hydroxysafflor yellow A on inflammatory signal transduction pathway related factors in rats with cerebral cortex ischemia].

Hydroxysafflor yellow A (HSYA) is a main active monomer purified from Carthamus tinctorius L. The research is to study the inhibitory effect of HSYA on the inflammatory signal transduction pathway related factors which were induced by permanent cerebral ischemia in rats. By using the successive administration at a 30 min interval of HSYA and the rats permanent focal cerebral ischemia model established by a intraluminal suture occlusion method.
