Quadruple therapy with immunotherapy and chemotherapy as first-line conversion treatment for unresectable advanced gastric adenocarcinoma: A case report.

Background: The treatment of gastric cancer remains highly challenging, particularly in cases of unresectable locally advanced or metastatic disease. Although chemotherapy and immunotherapy have shown some efficacy in such patients, significant limitations persist in extending survival and enhancing safety. To address these challenges, we designed an innovative first-line quadruple conversion therapy regimen that integrates a programmed cell death protein 1 (PD-1) inhibitor with chemotherapy, and we successfully implemented this therapy regimen in the treatment of a patient with unresectable locally advanced gastric adenocarcinoma.

Exogenous Glycinebetaine Promotes Soil Cadmium Uptake by Edible Amaranth Grown during Subtropical Hot Season.

Exogenous glycinebetaine treatment is an effective measure for preventing crops from being exposed to drought and high temperature; however, the effects of this approach on the soil Cd uptake and accumulation by crops remain unclear. Pot experiments were conducted in this study to analyze the effect of glycinebetaine on the soil Cd uptake and accumulation by edible amaranth cultivated in Cd-contaminated soil. Results revealed that after exogenous glycinebetaine treatment on amaranth leaves during the vigorous growth period, the plant biomass, the Cd concentrations in the roots and shoots, and the Cd translocation factor (TF) were significantly higher than those of the control group.
