Four polydiphenylacetylenes (PDPAs: C3, C6, C9, C12) containing different size of trialkylsilyl groups (C3: trimethyl; C6: triethyl; C9: trin-propyl; C12: trin-butyl) were prepared and their thermodynamic and hydrodynamic fluorescence (FL) emission b

Three different tetraphenylethylene derivatives (TPE18, TPE8, TPE1) with different-length alkyl chains (octadecyl, octyl, methyl) were prepared, and their viscosity (η) sensitivities were examined for hydrocarbons and silicone oils. Both TPE18 and T

Polydiphenylacetylene derivatives with different alkyl side chains (methyl, ethyl, and n-propyl groups) via a silylene linkage (PDPA-C1, PDPA-C2, PDPA-C3) were prepared. The polymer films were examined as a solid-state sensor for measuring the viscos

The gastrointestinal stromal tumor (GIST) is a mesenchymal tumor of the digestive tract showing differentiation along the line of interstitial cell of Cajal. The most GISTs in the stomach generally show the appearance of submucosal tumors. It is rare

Jejunal diverticula is a rare disease and an unusual cause of obscure gastrointestinal hemorrhage. Obscure gasterointestinal bleeding is difficult to treat because the bleeding site cannot be identified by routine endoscopy and contrast studies. A wi
