A Combination of Magnoflorine and Spinosin Improves the Antidepressant effects on CUMS Mouse Model.

Background: Depression is a common neuropsychiatric disease. As a famous traditional Chinese medicine with significant anti-depressive and sleep-promoting effects, Semen (ZSS) has attracted the attention of many researchers. Although it is well known that Magnoflorine (MAG) and Spinosin (SPI) were the main active components isolated from ZSS, there is a lack of research on the combined treatment of depression with these two ingredients.

Transcriptome and metabolome reveal the effects of three canopy types on the flavonoids and phenolic acids in 'Merlot' (Vitis vinifera L.) berry pericarp.

The flavonoids and phenolic acids in grape berries greatly influence the quality of wine. Various methods are used to shape and prune grapevines, but their effects on the flavonoids and phenolic acids remain unclear. The flavonoids and phenolic acids in the berry pericarps from grapevines pruned using three types of leaf canopy, namely, V-shaped, T-shaped, and vertical shoot-positioned (VSP) canopies, were compared in this study.

[DOM Characteristics Analysis of Surface Sediment-overlying Water in Suzhou Landscape River Course].

In order to understand the characteristics and interrelationship of dissolved organic matter (DOM) in interstitial water and overlying water of a landscape river in Suzhou, the characteristics of DOM in interstitial water and overlying water of landscape river sediments in the urban area of Suzhou from July to September after the 2020 flood season were analyzed using the UV-Vis absorption spectrum, high-performance liquid chromatography(HPLC), and fluorescence spectrum combined with the fluorescence region integration method. The results showed that the relative molecular weight of DOM in both the interstitial water and the overlying water was about 1000, and the relative molecular weight tended to increase in the same way over time. Both interstitial water and overlying water had the highest DOM of protein-like content, with a mass fraction that reached 68%-79%.

Untargeted metabolomics analysis of the anti-diabetic effect of Red ginseng extract in Type 2 diabetes Mellitus rats based on UHPLC-MS/MS.

Red ginseng is a traditional Chinese herbal medicine that has long been used to treat diabetes, and its blood sugar-lowering activity has been confirmed. However, the mechanism of action of red ginseng on type 2 diabetes mellitus (T2DM) at the metabolic level is still unclear. The purpose of this study is to investigate the effect of red ginseng extract in the treatment of T2DM rats based on untargeted metabolomics.

Plasma metabolomics-based reveals the treatment mechanism of ShenGui capsule for application to coronary heart disease in a rat model.

Shen Gui capsule (SGC) has been demonstrated to have a significant treatment effect for coronary heart disease (CHD). Nevertheless, the holistic therapeutic mechanism of SGC in vivo remain poorly interpreted. We aimed to systematically explore the preventive effect and mechanism of SGC on CHD rats using plasma metabolomics strategy.

[Spectral Characteristics and Sources of Dissolved Organic Matter from Landscape River During Flood Season in Suzhou Based on EEMs and UV-vis].

Based on excitation emission matrix spectroscopy (EEMs) technology combined with the parallel factor analysis (PARAFAC) and UV-vis spectra, the spectral characteristics and sources of dissolved organic matter (DOM) from a landscape river were analyzed during different periods of the flood season in Suzou. Four fluorescent components were identified using the PARAFAC model, including two humus-like components (C1, C4) and two protein-like components (C2, C3), with a significant correlation coefficient (<0.01) in C2 and C3/C4 and C3 and C4, respectively.

Use of magnoflorine-phospholipid complex to permeate blood-brain barrier and treat depression in the CUMS animal model.

To improve the liposolubility and blood-brain barrier permeability of magnoflorine, a new formulation of magnoflorine-phospholipid complex was prepared, characterized, and pharmacologically evaluated in the chronic unpredictable mild stress animal model. In this paper, the magnoflorine-phospholipid complex was synthesized and its characterization was determined. The antidepressant-like and antioxidant activity of magnoflorine-phospholipid complex was investigated by behavioral tests and western blotting analysis.

Nonlinear diffusion, bonding, and mechanics of the interface between austenitic steel and iron.

We investigate the atomic diffusivity and mechanics of the interface between bulk austenitic steel (fcc structure) and bcc iron at various temperatures and strain rates using molecular dynamics simulations. We adopt the system of FeCrNi corresponding to 316L steel as a representative model of austenitic steels, denoted as FeCrNi. We find that the compressive strength of the FeCrNi/Fe system decreases by 44.

Noninvasive delayed limb ischemic preconditioning in rats increases antioxidant activities in cerebral tissue during severe ischemia-reperfusion injury.

Background: To study the protection offered by noninvasive delayed limb ischemic preconditioning (NDLIP) against cerebral ischemia reperfusion (I/R) injury in rats.

Materials And Methods: Healthy male Wistar rats were randomly divided into four groups. The delayed protection offered by NDLIP was estimated in light of changes in the neural behavior marker and cerebral tissue antioxidative ability.

Non-invasive limb ischemic pre-conditioning reduces oxidative stress and attenuates myocardium ischemia-reperfusion injury in diabetic rats.

This study was to explore whether repeated non-invasive limb ischemic pre-conditioning (NLIP) can confer an equivalent cardioprotection against myocardial ischemia-reperfusion (I/R) injury in acute diabetic rats to the extent of conventional myocardial ischemic pre-conditioning (MIP) and whether or not the delayed protection of NLIP is mediated by reducing myocardial oxidative stress after ischemia-reperfusion. Streptozotocin-induced diabetic rats were randomized to four groups: Sham group, the I/R group, the MIP group and the NLIP group. Compared with the I/R group, both the NLIP and MIP groups showed an amelioration of ventricular arrhythmia, reduced myocardial infarct size, increased activities of total superoxide dismutase (SOD), manganese-SOD and glutathione peroxidase, increased expression of manganese-SOD mRNA and decreased xanthine oxidase activity and malondialdehyde concentration (All p < 0.

Limited sampling strategy in rats to predict the inhibited activities of hepatic CYP3A.

The present study was undertaken in order to evaluate feasibility of a limited sampling strategy (LSS) to predict the systemic clearance of midazolam (MDZ), which is a hepatic CYP3A activity phenotyping probe. Groups of rats pretreated with or without serial doses of ketoconazole, which is a selective inhibitor on CYP3A, were used as training set. Linear regression analysis and a Jack-knife validation procedure were performed based on plasma MDZ concentrations at specific time points after sublingual vein injection of MDZ to establish the most informative LSS equations for accurately estimating the clearance of MDZ.
