5β-hydroxycostic acid from Laggera alata ameliorates sepsis-associated acute kidney injury through its anti-inflammatory and anti-ferroptosis effects via NF-κB and MAPK pathways.

Ethnopharmacological Relevance: The whole plant of Laggera alata is frequently utilize to remedy inflammatory diseases including nephritis as a traditional Chinese medicine. However, its active ingredients and mechanism of action against sepsis-associated acute kidney injury (SA-AKI) are unknown.

Aim Of The Study: This study aimed to identify active compounds from L.

Photocatalytic Hydroxylation and Oxidative Coupling Reactions Mediated by Multinuclear Au(I) Supramolecular Clusters.

Polynuclear Au(I) cluster photocatalysts, known for their high activity and stability, hold substantial potential in organic synthetic chemistry. This study synthesized two Au(I) supramolecular cluster catalysts with different nuclearities: a tetranuclear cluster, C1 ([(dppmAu)L] • PF ), and a hexadecanuclear cluster, C2 [(dppmAu)(Au)(L)] • 4PF , through a multicomponent stepwise self-assembly approach. Both cluster structures feature aurophilicity interaction motifs that endow them with exceptional photocatalytic performance, exhibiting optical band gaps of 2.

The Corrosion Behavior of X100 Pipeline Steel in a Sodium Chloride Solution Containing Magnesium and Calcium.

The influences of Mg and Ca on the short-term (1800 s) corrosion behavior of X100 pipeline steel were investigated in a sodium chloride (NaCl) solution saturated with CO. Either Ca or Mg in the solution inhibited the short-term corrosion of X100 pipeline steel, with the corrosion current density decreasing from 262.4 μA cm to 163.

Tuning the Dielectric and Microwaves Absorption Properties of N-Doped Carbon Nanotubes by Boron Insertion.

It is of great significance to regulate the dielectric parameters and microstructure of carbon materials by elemental doping in pursuing microwave absorption (MA) materials of high performance. In this work, the surface electronic structure of N-doped CNTs was tuned by boron doping, in which the MA performance of CNTs was improved under the synergistic action of B and N atoms. The B,N-doped carbon nanotubes (B,N-CNTs) exhibited excellent MA performance, where the value of minimum reflection loss was -40.
