The processed Euphorbia lathyris L. alleviates the inflammatory injury via regulating LXRα/ABCA1 expression and TLR4 positioning to lipid rafts.

Euphorbia lathyris L. (EL) is a traditional poisonous herbal medicine used to treat dropsy, ascites, amenorrhea, anuria and constipation. Processing to reduce toxicity of EL is essential for its safe and effective application.

Composition and distribution of bacterial communities and potential radiation-resistant bacteria at different elevations in the eastern Pamirs.

Altitude and ultraviolet (UV) radiation may affect the community composition and distribution of microorganisms in soil ecosystems. In this study, 49 soil samples from 10 locations were collected from different elevations on the eastern Pamir Plateau and analyzed for soil microbial community structure and function using high-throughput sequencing. The results showed that soil samples from different elevations of the eastern Pamir Plateau contained 6834 OTUs in 26 phyla and 399 genera.

The Composition and Diversity of the Rhizosphere Bacterial Community of Ammodendron bifolium Growing in the Takeermohuer Desert Are Different from Those in the Nonrhizosphere.

Soil microorganisms play important roles in vegetation establishment and soil biogeochemical cycling. Ammodendron bifolium is a dominant sand-fixing (i.e.

sp. nov., isolated from rhizosphere soil of .

A Gram-negative, aerobic, gliding motile, rod-shaped bacterium, designated XAAS-72, was isolated from the rhizosphere soil of sampled in the Xinjiang Uyghur Autonomous Region, PR China. Cells grew at 4-45 °C, pH 5.0-8.

[Application research of entropy weight-based grey systematic theory in quality evaluation of Angelicae Sinensis Radix slices].

In order to discuss the "entropy weight method" for weighting various indicators in the comprehensive evaluation of Angelicae Sinensis Radix slices(ASR), the quality of ASR was comprehensively evaluated by entropy weight-based gray systematic theory and cluster analysis. In this study, the contents of ferulic acid, volatile oil, polysaccharide, alcohol extract, water extract, moisture, total ash and acid-insoluble ash in 44 batches of ASR from different sources were determined. The entropy weight method was used for objective weighting.

[Estimation of tissue's blood oxygen parameters from visible absorption spectrum of tissues by artificial neural network].

Total hemoglobin concentration (THC) and hemoglobin oxygen saturation (SO2) are essential parameters to doctors who wonder patients' hematogenous conditions and oxygen supplies and consumptions. Instruments presently used for measuring these parameters have big size of detecting probes that limit their applications to inner bodies. An optical probe involving two fibers with source-detector separations of one hundred micrometers was developed in the present study for purpose of minimally invasive inner detecting, which uses steady-state, broadband (300-1 000 nm) light source.

[Comparison of antitumor efficacy between arsacetyl and arsenic trioxide in vitro].

Background & Objective: Recently, it was reported that some organic arsenics was stronger than inorganic arsenics in inducing carcinoma cell apoptosis. This study was designed to compare arsacetyl (ASAC), a kind of organic arsenics, with As2O3 in the effect of inhibiting proliferation and inducing apoptosis in carcinoma cells.

Methods: MTT (Methythiazolyl tetrazolium) assay and analysis of apoptosis were used to evaluate the effects of arsacetyl and As2O3 on the proliferation of SMMC-7721 and their mechanisms.
