SATB1 mediated tumor colonization and β-catenin nuclear localization are associated with colorectal cancer progression.

Colorectal cancer (CRC) is a malignancy with high incidence and poor prognosis. It is urgent to identify valuable biomarkers for early diagnosis and potent therapeutic targets. It has been reported that SATB1 is associated with the malignant progression in CRC.

FTIR study on the CO interactions of benzeneacetamide in solution.

The main attention of present work is to study how benzeneacetamide interacts with other molecules in organic solvents. The frequencies of CO groups in 18 solvents were obtained by using infrared spectroscopy. The empirical parameters of the solvents as the acceptor number (AN), the van der Waals interaction parameters (S) and the linear solvation energy relationships (LSER) were correlated with the frequencies of carbonyl stretching vibration (ν(CO)) of benzeneacetamide to estimate the contributions in intermolecular interactions.

[Effects of aridity on carbon, nitrogen, and phosphorus contents in soils and plants of mountain swamps, Zhejiang, China].

Mountain swamps in Zhejiang Province have been suffered from severe drouhgt threats because of climate change and artificial interruption. bogs and swamps were gradually degraded into arid swamps. However, the effects of arid processes on the C, N, P contents of soils and their stoichiometry in mountain swamps are still unclear.

Preparative separation and purification of Cyclosporin D from fungus Hypoxylon Spp. by improved closed-loop recycling counter-current chromatography.

Improved closed-loop recycling counter-current chromatography (CLR CCC) with a two-phase solvent system composed of n-hexane-acetonitrile (1:1, v/v) was developed for separation, purification and preparation of cyclosporin D from the crude extract of fungus Hypoxylon Spp. (sj18). 28 mg cyclosporin D was successfully purified from 300 mg crude extract sample.

Preparative isolation and purification of antioxidative stilbene oligomers from Vitis chunganeniss using high-speed counter-current chromatography in stepwise elution mode.

Preparative high-speed counter-current chromatography (HSCCC) was successfully applied to the isolation and purification of three stilbene oligomers from Vitis chunganeniss using stepwise elution with a pair of two-phase solvent systems composed of n-hexane-ethyl acetate-methanol-water at (2:5:2:5, v/v) and (1:2:1:2, v/v). The preparative HSCCC separation was performed on 800 mg of crude sample yielding hopeaphenol (21.1 mg), amurensin G (37.

Infrared study of 6-methylcoumarin in binary solvent mixtures.

The infrared absorption spectra of the carbonyl stretching vibrations of 6-methylcoumarin (6MC) have been investigated in CCl4/ROH mixtures (CCl4/C2H5OH, CCl4/n-C3H7OH, CCl4/i-C3H7OH, and CCl4/t-C5H11OH). Two types of carbonyl stretching vibration bands for 6MC are found with the change of the mole fraction of the aprotic solvent CCl4(X CCl4 in binary solvent mixtures. The dependencies of the frequencies of carbonyl stretching vibrations upsilon(C=O) on X CCl4 allow a distinction and assignment of all species resulting from the solvent-solute interactions.
