An extendable all-in-one injection twin derivatization LC-MS/MS strategy for the absolute quantification of multiple chemical-group-based submetabolomes.

Huang Y, Jiao Y, Gao Y, Zhang P, Huang W, Liu Y, Huang Y, Tian Y, Wan JB, Zhang Z, Hao K, Xu F.
Analytica chimica acta. 2019 Jul;1063()99-109.
The ability of LC-MS/MS for high coverage metabolite analysis lags behind the requirements of global metabolomics. The introduction of chemical derivatizations could significantly extend the ability of LC-MS/MS with enhanced MS response and improved LC separation, which has been serving as a promisi

Instrument-free argentometric determination of chloride via trapezoidal distance-based microfluidic paper devices.

Rahbar M, Paull B, Macka M.
Analytica chimica acta. 2019 Jul;1063()1-8.
Chloride (Cl) is an inorganic anion present in a broad range of samples (e.g. biological, environmental, food, water, etc.), the determination of which is of widespread significance. In this work, we translate the well-established traditional argentometric method (Mohr's precipitation titration) int

Troxerutin attenuates myocardial cell apoptosis following myocardial ischemia-reperfusion injury through inhibition of miR-146a-5p expression.

Shu L, Zhang W, Huang G, Huang C, Zhu X, Su G, Xu J.
Journal of cellular physiology. 2019 Jun;234(6)9274-9282.
The aim of the current study was to investigate the effects and the underlying mechanisms of troxerutin on myocardial cell apoptosis during ischemia-reperfusion (I/R) injury. Hypoxia/reoxygenation (H/R) model in neonatal rat cardiomyocytes, and I/R model in rats, were established following troxeruti
