Two new monoterpene glycosides from the endophytic fungus and their cytotoxic effects.

Two new monoterpene glycosides, diaporthosides A () and B (), were purified from an endophytic fungus isolated from the medicinal plant . Their structures were determined by comprehensive spectroscopic analysis. The absolute configuration of compound was assigned by comparing its experimental ECD spectrum with the calculated spectrum using quantum-chemical ECD calculations.

Removal of high concentrations of zinc, cadmium, and nickel heavy metals by Bacillus and Comamonas through microbially induced carbonate precipitation.

Heavy metal pollution in urban freshwater, driven by anthropogenic activities, poses significant risks to aquatic ecosystems and human health due to its toxicity and persistence. Recently, urease-producing bacteria have gained attention for their ability to remove heavy metals through microbial-induced carbonate precipitation (MICP). In this study, eight urease-producing bacteria were exposed to individual solutions of zinc (Zn), cadmium (Cd), and nickel (Ni) at concentrations ranging from 0 to 6 mM to assess their resistance.

gene expression as a prognostic marker for clinical outcomes in lung adenocarcinoma.

Background: Lung adenocarcinoma (LUAD) is the predominant histological subtype of lung cancer. In the past decade, various targeted drugs have prolonged the survival of LUAD patients. Unfortunately, not all LUAD patients can benefit from the current target agents.

Synergistic biocementation: harnessing Comamonas and Bacillus ureolytic bacteria for enhanced sand stabilization.

Biocementation, driven by ureolytic bacteria and their biochemical activities, has evolved as a powerful technology for soil stabilization, crack repair, and bioremediation. Ureolytic bacteria play a crucial role in calcium carbonate precipitation through their enzymatic activity, hydrolyzing urea to produce carbonate ions and elevate pH, thus creating favorable conditions for the precipitation of calcium carbonate. While extensive research has explored the ability of ureolytic bacteria isolated from natural environments or culture conditions, bacterial synergy is often unexplored or under-reported.

Tigliane-and daphnane-type diterpenoids from the buds of with their cytotoxic activities.

Two new tigliane- and daphnane-type diterpenoids, given the trivial names daphnegens A-B - were isolated from the buds of . Their structures were assigned on the basis of extensive spectroscopic. The absolute configurations of both compounds were determined by comparison of their calculated and experimental CD curves.
