Gastric Cancer: Epidemiology, Risk Factors, Pathogenesis, Clinical Features, Diagnosis, and Management

open access: yesMedComm, Volume 7, Issue 11, November 2026.
This comprehensive review summarizes gastric cancer epidemiology, multifactorial risk factors (like infectious, dietary, genetic), pathogenesis such as precancerous evolution, molecular alterations, and a focus on the bidirectional interactions between gastric cancer cells and macrophages in the tumor microenvironment.

Continuous Imaging of the Cardiac Cycle Metabolism With Hyperpolarized [1‐13C]Pyruvate

open access: yesNMR in Biomedicine, Volume 39, Issue 11, November 2026.
We present a continuous hyperpolarized 13C MRI framework for phase‐resolved imaging of myocardial metabolism throughout the entire cardiac cycle. By combining spectral‐spatial bicarbonate excitation with frequency‐shifted reconstruction of residual pyruvate signal, both metabolites are obtained from a single acquisition.

Tuning the Triazolotriazine Scaffold Toward Selective A3 Adenosine Receptor Antagonists: From Molecular Recognition to Neuroprotection

open access: yesChemMedChem, Volume 21, Issue 20, 28 October 2026.
Structure‐based optimization of the triazolo‐triazine scaffold afforded highly potent and selective adenosine A3 receptor antagonists. Replacement of the classical 2‐furyl group with phenyl‐based substituents markedly improved A3 receptor affinity and selectivity.
