A sample obtained by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) revealed the histopathological proliferation of spindle-shaped bundles of atypical cells, and immunohistochemical(More)
Helicobacter pylori(H. pylori) are an organism that can be confidently recognized by histology. Using histological specimens, we can both identify infection and assess pathological condition associated with H. pylori. For the precise diagnosis, biopsies should be taken from suitable sites(greater curvature of antrum and corpus) and the valuable requirements(More)
We report asymmetric allylic alkylation of allylic chloride with β-diketones as the prochiral carbon nucleophiles using a planar-chiral Cp'Ru catalyst. The reaction proceeds under mild conditions; the resulting chiral products containing vicinal tertiary stereocenters are obtained with high regio-, diastereo-, and enantioselectivities. These chiral products(More)
