Role of salvianolic acid B in the treatment of acute ischemic stroke: a systematic review and meta-analysis of animal models.

Background: Salvianolic acid B (Sal B) is potentially the most valuable water-soluble active component in Salvia miltiorrhiza. Its chemical formula contains multiple phenolic hydroxyl groups, so it has a strong antioxidant capacity.

Objective: We aim to investigate the efficacy and the potential mechanism of Sal B in the treatment of acute ischemic stroke injury.

ARGET-ATRP-Mediated Grafting of Bifunctional Polymers onto Silica Nanoparticles Fillers for Boosting the Performance of High-Capacity All-Solid-State Lithium-Sulfur Batteries with Polymer Solid Electrolytes.

The shuttle effect in lithium-sulfur batteries, which leads to rapid capacity decay, can be effectively suppressed by solid polymer electrolytes. However, the lithium-ion conductivity of polyethylene oxide-based solid electrolytes is relatively low, resulting in low reversible capacity and poor cycling stability of the batteries. In this study, we employed the activator generated through electron transfer atom transfer radical polymerization to graft modify the surface of silica nanoparticles with a bifunctional monomer, 2-acrylamide-2-methylpropanesulfonate, which possesses sulfonic acid groups with low dissociation energy for facilitating Li migration and transfer, as well as amide groups capable of forming hydrogen bonds with polyethylene oxide chains.

Efficacy and safety of roxadustat for the treatment of anemia in non-dialysis chronic kidney disease patients: A systematic review and meta-analysis of randomized double-blind controlled clinical trials.

Objective: To evaluate the efficacy and safety of roxadustat in the treatment of anemia in non-dialysis-dependent chronic kidney disease (NDD-CKD) patients.

Materials And Methods: For this systematic review and meta-analysis, we searched for randomized controlled trials (RCTs) of anemia in NDD-CKD patients to assess the efficacy and safety of roxadustat. The primary efficacy endpoint was the proportion of patients who achieved a hemoglobin (Hb) response.

How does new environmental law affect public environmental protection activities in China? Evidence from structural equation model analysis on legal cognition.

To investigate the validity of Chinese law enforcement from the public's perspective, this research applies the theory of planned behavior, and introduces law as a moderator variable to explore the determinants of public's environmental behaviors. Results from an empirical study of China indicate that perceived behavioral control, subjective norms, inward attitude, and outward attitude all have positive impacts on environmental intentions and indirectly affect the citizens' environmental behavior and activists' environmental behavior. Meanwhile, legal cognition positively moderates the relationship between environmental intentions and behaviors.
