The progress in our understanding of early events in the development of colonic neoplasia
is the result of 2 advances:(1) improved characterization of lesions detected at endoscopy …

Many clinical studies on narrow‐band imaging (NBI) magnifying endoscopy classifications
advocated so far in Japan (Sano, Hiroshima, Showa, and Jikei classifications) have reported …

… , human leukemic T-cell lines, and rat lymphocytes. Stimulation of T-lymphocytes with …
argues that ACh synthesized and released from T-lymphocytes acts as an autocrine and/or …

Background Pembrolizumab is active in head and neck squamous cell carcinoma (HNSCC),
with programmed cell death ligand 1 (PD-L1) expression associated with improved …

Roughened surfaces of light-emitting diodes (LEDs) provide substantial improvement in light
extraction efficiency. By using the laser-lift-off technique followed by an anisotropic etching …

We report on a systematic analysis of x-ray photoelectron spectroscopy (XPS) core-and
valence-level spectra of clean and well-characterized iron oxide films, ie, α− Fe 2 O 3, γ− Fe 2 O …

Background Flat and depressed colorectal tumours were originally thought to be unique to
the Japanese population. Recently there have been reports of flat and depressed lesions in …

We have characterized the vertical transport properties of epitaxial layered structures
composed of Pr 0.7 Ca 0.3 Mn O 3 (PCMO) sandwiched between Sr Ru O 3 (SRO) bottom …

… Some engrafted MSCs were positive for the cardiac markers desmin, cardiac troponin T,
and connexin-43, whereas others formed vascular structures and were positive for von …

Studies of field-effect control of the high mobility electrons in MBE-grown selectively doped
GaAs/n-Al x Ga 1-x As heterojunctions are described. Successful fabrication of a new field-…
