Objective: Cognitive impairment (CI) is highly prevalent in subarachnoid hemorrhage (SAH) patients. The phosphatidylinositol 3-kinase (PI3K)/AKT pathway plays a critical role in neuronal survival in a variety of central nervous system injuries. This study aimed to determine whether electroacupuncture (EA) at and LI20 ameliorates SAH-CI in a rat model and to examine whether it modulates the PI3K/AKT pathway by administering a PI3K inhibitor (LY294002) versus dimethyl sulfoxide (DMSO) vehicle.

Background: A primary factor in the pathogenesis of aging is oxidative stress, with cardiac inflammation and fibrosis being contributed to by increased oxidative stress as organisms age. Oxidative stress enhances the cardiac fibrotic signaling pathway, with reactive oxygen species inducing cardiac fibrosis through increased expression of the profibrotic factor transforming growth factor-beta 1 (TGF-β1). Furthermore, Wnt/β-catenin signaling pathway is implicated in interstitial fibrosis, which is associated with TGF-β.

A cost-effective, eco-friendly, and highly efficient one-pot electrochemical process has been described for the synthesis of 4-1,3-benzoxazine and 4,5-dihydro-1,3-benzoxazepine derivatives by employing 2-aminobenzyl alcohols, 2-(2-aminophenyl)ethan-1-ol, isothiocyanate derivatives, and TBAPF as an electrolyte. The developed method is accomplished at 25 °C with a constant current of 20 mA. Utilizing a graphite anode and a platinum cathode in a dimethyl sulfoxide solvent, the devised metal-free electrochemical approach minimizes the production of waste and eliminates the need for external oxidizing agents.

However, CBD susceptibility to oxidation and resulting toxicity dissolved in two common solvents, ethanol (EtOH) and dimethyl sulfoxide (DMSO), is seldom discussed. Furthermore, CBD products contain a wide range of concentrations, making it challenging to link general health risks associated with CBD cytotoxicity.

This study aimed to investigate, in vitro, the toxicity of WTA on ovarian follicles. Initially, a cytotoxicity assay was conducted using tumor and non-tumor cell lines to determine the ICof the WTA and validate its antitumor activity. Mouse ovaries were cultured in vitro (IVC) for 6 days in the presence of 1% dimethyl sulfoxide (DMSO), doxorubicin at 0.
