Objective: NvZhen ErXian HeJi (NZEXHJ) is used to treat perimenopausal syndrome (PS), but its effect on perimenopausal coronary heart disease is unclear. Furthermore, the aim of this research is to study the effect of NZEXHJ on perimenopausal coronary heart disease (PMCHD) in a rat model based on a network pharmacology approach.
Materials And Methods: Based on network pharmacological analysis combined with molecular docking, we predicted the potential therapeutic target and pharmacological mechanism of NZEXHJ in the treatment of PMCHD. We used an ovariectomized rat (OVR) model to understand the effect of NZEXHJ on myocardial injury and further verified the target of NZEXHJ in the intervention of PMCHD.
Results: We selected 52 active components of NZEXHJ against PMCHD and an intersection of their targets on network pharmacology, to which SCN5A, SER1, AR, and PGR were significantly correlated. The protein- protein interaction network revealed CASP3, CXCL8, IL6, MAPK1, TNF, TP53, and VEGFA in the treatment of PMCHD with NZEXHJ. Kaempferol, luteolin, and mistletoe presented good affinity towards the aforementioned targets by Molecular docking NZEXHJ exerted protecting cardiomyocytes for OVR. The mechanism was related to a reduction in the expression levels of the CXCL8, TNF, and regulating PI3K-Akt signaling pathways.
Conclusion: This study reveals the potential multi-component, multi-target, and multi-pathway pharmacological effects of NZEXHJ and predicts its protection against myocardial infarction in ovariectomized rats through the PI3K Akt pathway, providing a theoretical basis for the treatment of PMCHD.

Limited treatment options are available for bladder cancer (BCa) resulting in extremely high mortality rates. Cyclovirobuxine D (CVB-D), a naturally alkaloid, reportedly exhibits notable antitumor activity against diverse tumor types. However, its impact on CVB-D on BCa and its precise molecular targets remain unexplored.

Phenomic selection based on parental spectra can be used to predict GCA and SCA in a sparse factorial design. Prediction approaches such as genomic selection can be game changers in hybrid breeding. They allow predicting the genetic values of hybrids without the need for their physical production.

As a special kind of supramolecular compound with many favorable properties, pillar[]arene-based supramolecular polymer networks (SPNs) show potential application in many fields. Although we have come a long way using pillar[]arene to prepare SPNs and construct a series of smart materials, it remains a challenge to enhance the mechanical strength of pillar[]arene-based SPNs. To address this issue, a new supramolecular regulation strategy was developed, which could precisely control the preparation of pillar[]arene-based SPN materials with excellent mechanical properties by adjusting the polymer network structures.

ConspectusWater-in-salt electrolytes (WiSEs) are promising electrolytes for next-generation lithium-ion batteries (LIBs), offering critical advantages like nonflammability and improved safety. These electrolytes have extremely high salt concentrations and exhibit unique solvation structures and transport mechanisms dominated by the formation of ion networks and aggregates. These ion networks are central to the performance of WiSEs, govern the transport properties and stability of the electrolyte, deviating from conventional dilute aqueous or organic electrolytes.
