Irisin attenuates vascular remodeling in hypertensive mice induced by Ang II by suppressing Ca-dependent endoplasmic reticulum stress in VSMCs.

Vascular remodeling plays a vital role in hypertensive diseases and is an important target for hypertension treatment. Irisin, a newly discovered myokine and adipokine, has been found to have beneficial effects on various cardiovascular diseases. However, the pharmacological effect of irisin in antagonizing hypertension-induced vascular remodeling is not well understood.

New and known phenylpropanoid glycosides from mountain cultivated ginseng.

Two new phenylpropanoid glycosides elucidated as 2,6-dimethoxyphenyl-4-propylene-1---D-apiofuranosyl-(1-6)--D-glucopyranoside () and 2-methoxyphenyl-4-propylene-1--D-apiofuranosyl-(1-6)-D-glucopyranoside (), along with three known phenylpropanoid glycosides (-) were isolated from Mountain Cultivated Ginseng. The structures of compounds - were elucidated on the basis of comprehensive spectroscopic data including 1D, 2D NMR spectra, and MS. In addition, in vitro cytotoxicity of all the isolated compounds was evaluated against HELA cell.

Early detection of tumor response by FLT/microPET Imaging in a C26 murine colon carcinoma solid tumor animal model.

Fluorine-18 fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) imaging demonstrated the change of glucose consumption of tumor cells, but problems with specificity and difficulties in early detection of tumor response to chemotherapy have led to the development of new PET tracers. Fluorine-18-fluorothymidine ((18)F-FLT) images cellular proliferation by entering the salvage pathway of DNA synthesis. In this study, we evaluate the early response of colon carcinoma to the chemotherapeutic drug, lipo-Dox, in C26 murine colorectal carcinoma-bearing mice by (18)F-FDG and (18)F-FLT.
