p-Synephrine exhibits anti-adipogenic activity by activating the Akt/GSK3β signaling pathway in 3T3-L1 adipocytes.

This work aimed to investigate the effects of p-synephrine on the differentiation of adipocyte and explore the underlying mechanism. We found that p-synephrine suppressed the 3T3-L1 cell adipogenesis by reducing the expression level of CCAAT/enhancer-binding protein α (C/EBPα) and peroxisome proliferator-activated receptor γ (PPARγ), which subsequently led to a reduction in the fatty acid-binding protein 4 (aP2) expression. p-Synephrine treatment markedly activated the protein kinase B (PKB/Akt) pathway and sequentially inhibited glycogen synthase kinase 3β (GSK3β) activity.

Paeonol ameliorates monosodium urate-induced arthritis in rats through inhibiting nuclear factor-κB-mediated proinflammatory cytokine production.

Moutan Cortex has been widely used to treat various types of arthritis in traditional Chinese medicine. Paeonol is isolated as an active ingredient from Moutan Cortex. However, the effect and potential mechanism of paeonol on gouty arthritis have not been evaluated.

Study on preparation method of Zanthoxylum bungeanum seeds kernel oil with zero trans-fatty acids.

The seed of Zanthoxylum bungeanum (Z. bungeanum) is a by-product of pepper production and rich in unsaturated fatty acid, cellulose, and protein. The seed oil obtained from traditional producing process by squeezing or extracting would be bad quality and could not be used as edible oil.

[Spectral calibration of hyperspectral imager based on spectral absorption target].

Retrieval of center wavelength and bandwidth is a key step for quantitative analysis of hyperspectral data. The present paper proposes a spectral calibration method of hyperspectral imager, whose spectrum covers visible and near-infrared band, using spectral absorption target. Ground calibration experiment was designed for a hyperspectral imager with a bandwidth of 6 nm.

[Activating effect of citrus flavonoids on neuromedin U2 receptor and analysis on siRNA interference].

Objective: To screen out active substances on Neuromedin U2 receptor (NMU2R) by using stable NMU2R cell lines and negative cell lines and analyzing siRNA interference.

Method: NMU2R cells were used to observe the activating effect of nine nine citrus flavonoids on NMU2R cell. Afterwards, false-positive interference of citrus flavonoids that showed higher activating effect was eliminated by using negative cells and analyzing the efficiency of siRNA interference.

[In-flight absolute radiometric calibration of UAV hyperspectral camera and its validation analysis].

With the data in Urad Front Banner, Inner Mongolia on November 14th, 2010, hyper-spectral camera on UAV was calibrated adopting reflectance-based method. During the in-flight absolute radiometric calibration, 6 hyper-spectral radiometric gray-scale targets were arranged in the validation field. These targets' reflectances are 4.
