Genetic Diversity and Phylogenetic Relationships of in Xinjiang, China, Revealed by Mitochondrial and D-loop Sequence Analyses.

is a subspecies of the Eurasian beaver that has a relatively small population size compared to other subspecies. There is limited genetic research on this subspecies. In this study, mitochondrial cytochrome b () and D-loop sequences were analysed in genetic samples obtained from 19 individuals residing in the Buergen River Basin, Xinjiang, China.

Development and validation of a novel prediction model for Carbapenem-resistant organism infection in a large-scale hospitalized patients.

Carbapenem-resistant organism (CRO) are defined as gram-negative bacteria. The lack of safe and effective antibiotics has led to an increase in incidence rate. The purpose of this study is to establish and determine a risk nomogram to predict CRO infection in hospitalized patients.

[Advance in saponins of aerial parts of Panax species].

The bioactivities, chemical composition and distribution of aerial parts of Panax species are different from the roots. The present paper summarized the phytochemical and analytical studies of aerial parts of Panax species, including P. ginseng, P.

Discrimination of leaves of Panax ginseng and P. quinquefolius by ultra high performance liquid chromatography quadrupole/time-of-flight mass spectrometry based metabolomics approach.

In present study, an ultra high performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS/MS) based metabolomics approach was established to investigate the metabolic profiles and characteristic chemical markers for distinguishing between leaves of Panax ginseng (LPG) and Panax quinquefolius (LPQ). The UHPLC-QTOF-MS/MS data were subjected to principal component analysis (PCA) and orthogonal partial least squared discrimination analysis (OPLS-DA) to rapidly find the potential characteristic components of LPG and LPQ, and the identities of detected peaks including the potential characteristic components were elucidated. Totally, 86 components were identified from these 2 kinds of leaf samples, in which 9 ginsenosides could be regarded as the characteristic chemical markers for the discrimination of LPG from LPQ.
