To solve the low accuracy and poor stability problems of traditional existing infusion pumps at microflow rates, a new conceptual design based on a giant magnetostrictive actuator (GMA) is proposed. The conceptual structure and working principle of the new infusion pump are introduced. A GMA for the core device was tested experimentally.

A novel high stability pH-sensitive smart film (GGPS-R-FA) was prepared by using gellan gum (GG) and potato starch (PS) as the film-forming material, red cabbage anthocyanins extract (RCAE) as the indicator, and ferulic acid (FA) as the co-pigmentation agent. The enhancement effect of co-pigmentation on the stability of RCAE, as well as the performance and application of smart film were investigated. The RCAE co-pigmented with FA showed higher absorbance and greater thermal stability, as evidenced by the retention of anthocyanin content and thermodynamic parameters.

This research was aimed at developing a novel pH-responsive smart film made of chitosan, zein and red radish anthocyanin (RRA). The morphology, interaction, crystallization, thermal stability, physiochemical properties and pH sensitivity of films were analyzed. The smart film was applied to monitor the freshness of mushroom (Agaricus bisporus).

In this paper, A. bisporus at different storage times was sequenced by Illumina Novaseq 6000 platform.

The paper focused on the role of ethanol on rheological properties of zein/chitosan film-forming solutions, thermo-mechanical and structural characterization of films. The steady rheological results indicated that the film-forming solutions showed non-Newtonian behavior, and ZC-3 solution (zein treated with 90% ethanol and chitosan dissolved with acetic acid) had higher flow index (0.882±0.

To explore new noninvasive treatment options for depression, this study investigated the effects of electric acupuncture (EA) for depression rat models. Depression in rats was induced by unpredictable chronic mild stress (UCMS) combined with isolation for 21 days. Eighteen male Sprague-Dawley rats were randomly assigned into three groups: control, model, and EA groups.

Methods: Twenty-four SD rats were randomly divided into a control group, a model group and an EA group, 8 cases in each one. Rats in the control group were treated with normal diet for 21 days without any treatment.
