Chloroplast Genome Evolution and Species Identification of (Styracaceae).

The genus L. consists of approximately 130 species distributed in the Americas, eastern Asia, and the Mediterranean region. The phylogeny and evolutionary history of this genus are not clear.

[Application of traditional Chinese medicine(TCM) traceability system based on TCM quality characteristics and HACCP system].

It is crucial to establish a complete set of traditional Chinese medicine(TCM) quality traceability management process system, in order to stabilize the pricing order of TCM market and reconstruct the transmission path of TCM quality signals. In this study, we reviewed the mature experience of food and drug supervision at home and abroad, analyzed the quality characteristics of TCM, and put forward that the quality control of TCM products can learn from the hazard analysis and critical control point(HACCP) system in food safety quality control. This study points out that the HACCP system provides not only technical guidance for the traceability management of TCM, but also ideas for improving the quality of TCM products and the safety risk control of TCM.

Characterization of the complete chloroplast genome sequence of Dalbergia species and its phylogenetic implications.

The pantropical plant genus Dalbergia comprises approximately 250 species, most of which have a high economic and ecological value. However, these species are among the most threatened due to illegal logging and the timber trade. To enforce protective legislation and ensure effective conservation of Dalbergia species, the identity of wood being traded must be accurately validated.

Characterization of complete chloroplast genome of traditional Chinese medical plants and its phylogenetic positions.

The genus (Liliaceae) has been used for traditional medicine in China. The wild was on the verge of exhaustion due to illegal and immoderate exploitation coupled with environmental pollution. In order to alleviate resource pressure, can be considered as alternative sources.

Comparative Chloroplast Genomes of Species: Sequence Divergence and Phylogenetic Relationships.

Sorghum comprises 31 species that exhibit considerable morphological and ecological diversity. The phylogenetic relationships among S species still remain unresolved due to lower information on the traditional DNA markers, which provides a limited resolution for identifying species. In this study, we sequenced the complete chloroplast genomes of and and analyzed the published chloroplast genomes of and to retrieve valuable chloroplast molecular resources for .

Development of Chloroplast Genomic Resources for Species Discrimination.

Rice is the most important crop in the world as the staple food for over half of the population. The wild species of represent an enormous gene pool for genetic improvement of rice cultivars. Accurate and rapid identification of these species is critical for effective utilization of the wild rice germplasm.

Chloroplast Genomic Resource of Paris for Species Discrimination.

Paris is famous in China for its medicinal value and has been included in the Chinese Pharmacopoeia. Inaccurate identification of these species could confound their effective exploration, conservation, and domestication. Due to the plasticity of the morphological characteristics, correct identification among Paris species remains problematic.

The complete chloroplast genome of traditional Chinese medical plants Paris polyphylla var. yunnanensis.

Paris polyphylla var. yunnanensis is a perennial medical plant widely used in traditional Chinese medicine. Here, we report the complete chloroplast genome of P.

A pseudopotential method for investigating the surface roughness effect in ultrathin body transistors.

An atomistic method based on the diffraction pseudopotential model is established, for investigating the surface roughness (SR) effect in ultrathin body double-gate metal-oxide-semiconductor field effect transistors. The scattering of electrons due to atoms and vacancies responsible for roughness results from a three-dimensional effective field, and its planar components provide essentially roughness scattering, while a vertical effective field is the source of scattering in the method developed in which roughness is treated as a semiclassical barrier fluctuation. The present model involves a stronger effect on mobility than the previously developed one and results in an excellent fit, as regards mobility, to the reported experimental data.

[Therapeutic effect of "anti-hepatic-fibrosis 268" on hepatic fibrosis in rats].

Objective: To investigate the effects of the proprietary Chinese Medicine "anti-hepatic-fibrosis 268" on hepatic fibrosis and the related mechanisms.

Methods: The model of CCl4-induced hepatic damage was established in SD rats. 54 male rats were divided into four groups, namely high dose and low dose "anti-hepatic-fibrosis 268" groups, colchicine control group, and model control group.
