The Qinghai-Tibetan Plateau (QTP) is the highest and one of the most extensive plateaus in the world. Phylogenetic, phylogeographic, and ecological studies support plant diversifications on the QTP through multiple mechanisms such as allopatric speciation via geographic isolation, climatic oscillations and divergences, pollinator-mediated isolation, diploid(More)
Rhodiola L. (Crassulaceae) is a mid-sized plant genus consisting of about 70 species, with most species distributed on the Qinghai-Tibetan Plateau (QTP) and the adjacent areas, and several species in north-east Asia, Europe, and North America. This study explored the origin and diversification history of Rhodiola and tested the biogeographic relationships(More)
DNA barcoding, the identification of species using one or a few short standardized DNA sequences, is an important complement to traditional taxonomy. However, there are particular challenges for barcoding plants, especially for species with complex evolutionary histories. We herein evaluated the utility of five candidate sequences - rbcL, matK, trnH-psbA,(More)
The evolution and current distribution of the Sino-Tibetan flora have been greatly affected by historical geological events, such as the uplift of the Qinghai-Tibetan Plateau (QTP), and Quaternary climatic oscillations. Rhodiola kirilowii, a perennial herb with its distribution ranging from the southeastern QTP and the Hengduan Mountains (HM) to adjacent(More)
AIMS To assess the association and the predictive value of plasma homocysteine (Hcy) with early recurrence in persistent atrial fibrillation patients after a single ablation procedure. METHODS AND RESULTS Two hundred and fifty-seven consecutive patients with persistent atrial fibrillation who underwent successful catheter ablation were enrolled. Early(More)
OBJECTIVE To discuss the trend of displacement on the side of nondistraction when distraction osteogenesis with unilateral incomplete osteotomy of canine mandible. METHODS The method of finite element analysis was used to simulate distraction osteogenesis with unilateral incomplete osteotomy and the displacement of six marked point such as the(More)
Angiotensin II receptor blockers (ARB) are widely used drugs that are proven to reduce cardiovascular disease events; however, several recent meta-analyses yielded conflicting conclusions regarding the relationship between ARB and cancer incidence, especially when ARB are combined with angiotensin-converting enzyme inhibitors (ACEI).We investigated the risk(More)
OBJECTIVE To explore the expression changes of proliferating cell nuclear antigen (PCNA) in oral normal mucosa and recurrent aphthous ulcers(RAU). METHODS The expression intensity and distribution of PCNA were examined with immunohistochemistry method in 15 cases of recurrent oral aphthous and normal oral mucosa. RESULTS In RAU, there was large amount(More)
In order to investigate the characteristics of polycyclic aromatic hydrocarbons (PAHs) in ashes from coking, PAHs in ashes from three coke production plants were analyzed with GC-MS, and the distribution characteristics of PAHs and potential toxicity risk were discussed. The sum of 16 EPA prior PAHs varied from 8.17 x 10(2) to 5.17 x 10(3) microg x g(-1).(More)
A phosphate-solubilizing bacterium, designated CPCC 100624T, was isolated from a fresh water reservoir in south-west China. The 16S rRNA gene sequence comparison of strain CPCC 100624T with the available sequences in the GenBank database showed that the isolate was closely related to the members of the genus Spirosoma. In the phylogenetic tree based on 16S(More)
