Effects of transcutaneous electrical acupoint stimulation on upper-limb impairment after stroke: A randomized, controlled, single-blind trial.

Objective: To evaluate the effects of transcutaneous electrical acupoint stimulation (TEAS) on upper limb motor recovery during post-stroke rehabilitation.

Design: Single-blind, randomized controlled trial.

Setting: Four inpatient rehabilitation facilities.

Copper(II)-β-cyclodextrin and CuO functionalized graphene oxide composite for fast removal of thiophenic sulfides with high efficiency.

A novel copper(II)-β-cyclodextrin and CuO functionalized graphene oxide composite (CD-CuO/NH-GO) was successfully synthesized by reacting mono-6-O-toluenesulfonyl-copper(II)-β-cyclodextrin with amino and CuO functionalized graphene oxide. The characterization results showed that the CD-CuO/NH-GO was well-characterized and has a BET surface area of 746.5 m g and good thermal stability, and CD and CuO were uniformly dispersed.

New determination method for sulfonation degree of phthalic anhydride by RP-HPLC.

A novel method was developed to monitor the reaction process and evaluate the sulfonation level in the sulfonation of phthalic anhydride by reversed-phase high-performance liquid chromatography (RP-HPLC). The product peak was identified in chromatograms through product analysis and by comparing its retention time with that of standard compounds. By comparing the hydrolysis and alcoholysis methods, optimized pretreatment of the sample was found for RP-HPLC.

Solid base for hydrogen sulfide removal in light oil.

Three solid bases, with three kinds of activated carbon as supporters and alkaline materials as active components, were tested for hydrogen sulfide removal in light oil. The solid bases have high intensity and greater adsorption capacity for hydrogen sulfide removal and are more easily regenerated.
