Article Synopsis
  • Synchronous gastric tumors featuring both gastrointestinal stromal tumors (GIST) and adenocarcinoma are uncommon; this study analyzed six such cases.
  • All GIST cells in these tumors showed specific markers (CD117, CD34, and Dog1) through immunohistochemical analysis.
  • Genetic sequencing revealed that exon 11 c-kit mutations were present in some tumors, with a higher mutation rate found in GIST alone compared to those paired with adenocarcinoma.

A new caffeic acid tetramer compound, named (+) methyl rabdosiin (4), together with seven known caffeic acid multimers (1-3, 5-8) and one caffeic acid monomer (9), were isolated from the aerial parts of Dracocephalum moldavica L. The structures of these compounds were assigned on the basis of 1D and 2D NMR spectroscopic and mass spectrometry analyses. The protective effects of compounds 2-4 against hydrogen peroxide (HO)-induced apoptosis were evaluated in primary cardiomyocytes of SD neonatal rats in vitro by the MTT method.
