Promotion of HepG2 cell apoptosis by Sedum emarginatum Migo and the mechanism of action.

Background: Sedum emarginatum Migo(S. emarginatum) has anti-tumor and anti-oxidant effects. This study aimed to screen the extractions of S.

The effect of 8-OH-DPAT and dapoxetine on gene expression in the brain of male rats during ejaculation.

The 5-HT receptor agonist 8-hydroxy-2-[di--propylamino] tetralin (8-OH-DPAT) promotes ejaculation of male rats, whereas dapoxetine delays this process. However, the gene expression profile of the brain at ejaculation following administrationof these two compounds has not been fully elucidated. In the present study, a transcriptomic BodyMap was generated by conducting mRNA-Seq on brain samples of male Sprague-Dawley rats.

Profiles of brain central nervous system gene expression associated with ejaculation behavior in male rats.

The male rat has been used extensively as a model for evaluating the neurophysiology of sexual behavior. However, gene expression in the brain throughout the process of sexual intercourse has yet to be elucidated. In the present study, we created a transcriptomic BodyMap by performing mRNA-Seq on brain samples from pre-copulatory control (CK), fourth intromission (CR4), ejaculation (EJ) and post-ejaculatory interval 1-min (PEI1) Sprague Dawley rats (n=40, all male, each 10).

Liquid chromatography with tandem mass spectrometry method for the simultaneous determination of multiple sweet mogrosides in the fruits of Siraitia grosvenorii and its marketed sweeteners.

A high-performance liquid chromatography with electrospray ionization tandem mass spectrometry method has been developed and validated for the simultaneous quantification of eight major sweet mogrosides in different batches of the fruits of Siraitia grosvenorii and its marketed sweeteners. The sample preparation procedure and chromatographic and mass spectrographic conditions were optimized. Chromatographic separation was achieved on a reversed-phase Poroshell 120 SB C column in 10.
